1. INTRODUCTION

Geosyntec has prepared the following work plan to describe supplemental site characterization intended to provide additional data to support completion of an Engineering Evaluation/Cost Analysis (EE/CA) for the U.S. Fish and Wildlife Service (FWS) at Gunpowder Point, Chula Vista, CA. The EE/CA is being performed in general accordance with 40 CFR 300.415, and was authorized under GSA contract GS10F0106M, FWS Delivery Order No. F11PD03291. The FWS has the authority to undertake Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) response actions, under 42 United States Code (USC) 9604, 10 USC 2705, and Federal Executive Order 12580.

Geosyntec has completed a thorough review of existing data provided by FWS, conducted a preliminary screening of existing data relative to screening levels for soil and groundwater, and identified data gaps, as described herein. In addition to summarizing the results of these activities, this work plan provides the framework for conducting the supplemental site investigation.

2. SITE DESCRIPTION

The Gunpowder Point Site includes a 30-acre upland feature that juts westward into San Diego Bay from the surrounding Sweetwater Marsh area that is commonly referred to as “Gunpowder Point” (Site). The eastern portion of Gunpowder Point is occupied by the Chula Vista Nature Center, a visitor’s center, walking paths, and various bird restoration habitats. The Site location is shown on Figure 1.

Specific site location information is summarized below:

Address (address is provided for the Chula Vista Nature Center, located within the Study Area)

1000 Gunpowder Point, Chula Vista CA 91910-8222

Elevation (feet above mean sea level [msl]) 4 – 16 feet above msl

Latitude North 32.639510 / 32° 38’ 22.2”

Longitude East 117.112440 / 117° 6’ 44.8”

Township, Range, Section T:18S, R: 2W, S: 5

The Site was previously occupied by industrial facilities during the first half of the twentieth century and was used for the production of potash and acetone, followed by cotton seed-based

OU 2 001585


products, and agricultural operations. Remnants of concrete structures, concrete building pads, and other features related to former operations remain throughout the Site.

3. BACKGROUND

From 1916 through 1919 during World War I, the Hercules Powder Company (Hercules) operated a 30-acre industrial complex to produce potash and acetone from kelp that was harvested off-shore. The facility consisted of 156 above-ground, 50,000-gallon, wooden fermentation tanks, a shoreline pier with piping, and rail lines utilized for moving material from one part of the plant to another. In addition to the fermentation tanks, the plant also included nine large storage tanks (each holding 400,000 gallons), basins and a reservoir with the capacity to hold millions of gallons (apparently for storage of post-fermentation kelp liquor), fusing furnaces (to produce acetic anhydride and some potash), large crystallization tanks (to produce calcium salts of organic acids and potash), evaporators (to produce acetone), an onsite railroad system, pipelines, a laboratory, and storage buildings (Jones and Stokes, 2008). The plant was the largest of its type in the world until it was closed in 1919.

Raw sea kelp was harvested off shore by several kelp harvesting barges and delivered to the facility via a pipe running the length of a pier, where the kelp was loaded into the on-shore wooden tanks for fermentation. Following fermentation, the kelp liquor was pumped into new tanks where lime was added to kill aerobic bacteria in order to halt the fermentation process. The addition of lime caused the formation of calcium salts, which were in solution along with potash and other soluble salts (Neushul, 1992). Following the fermentation, the kelp liquor was crystallized to produce various salts. Crystallization took place in a hot and cold house, with acetone bearing salts precipitated in the hot kettles and potash salts precipitated in the cold kettles, as follows. The first product to crystallize was a mixture of calcium salts referred to as "taffy" that was later used in the production of high-grade solvents such as ethyl butyrate, ethyl propionate, methyl-ethyl-ketone, and other higher ketones. The second product to crystallize was calcium acetate along with a small percentage of potash. The remaining liquor was placed in the cold kettles, producing a whitish powder that was 95 to 98 percent pure potassium chloride (Neushul, 1992).

Following the Hercules operations, Pacific Cottonseed Products Corporation utilized the Site, including remaining structures left by Hercules from approximately 1920 to 1946 for production of cottonseed oil. The cottonseed was grown elsewhere and brought to the Site for processing. Facilities for the Pacific Cottonseed Products Corporation occupied approximately 10 acres. Structures and operations included the hull house, the mill (to extract the crude oil), cottonseed meal storage, a refinery, oil storage tanks, a machine shop, and cottonseed storage buildings. Chief constituents of cottonseed oil are glycerides of palmitic, oleic, and linoleic acids.

Areas near Gunpowder Point also were used for farming as early as the 1920s (FWS, 2008). In particular, the area east of the former Hercules operation area was repeatedly used for

OU 2 001586


agriculture. From 1946 to 1986, the eastern portion of the Site was used for agriculture, and in 1988 the FWS established the Site as a national wildlife refuge.

A detailed Site history and discussion of previous environmental studies are provided in the October 2011 Final Preliminary Assessment/Site Investigation (PA/SI) report completed by the FWS (FWS, 2011).

4. PHYSICAL SETTING

4.1 Topography

Gunpowder Point is a natural upland feature at approximately 10 feet higher elevation than the surrounding Sweetwater Marsh. The Site is gently rolling and is covered with sparse vegetation or bare soil. Localized disturbed areas (mounds and constructed berms) from the former industrial operations are approximately 10 to 15 feet high in elevation. Former building remnants and other features related to former operations remain throughout the Site, including several large depressed areas that were former settling basins and a reservoir. These former Site features are discussed in more detail below in Section 5.

4.2 Surface Water

The Site is located in San Diego Bay, which is connected to the Pacific Ocean. The Sweetwater River runs along the northern side of Gunpowder Point, and many small streams are present through the marsh surrounding the Site. The Sweetwater Flood Control Channel, constructed by the U.S. Army Corps of Engineers (USACE) in the mid-1980s, is located further north of the Site. This and previous historic revisions of the Sweetwater River significantly altered the hydrodynamics of Sweetwater Marsh. San Diego Bay receives minimal freshwater input and has a high evaporation rate, and freshwater contributions come primarily from the Otay and Sweetwater rivers, with some minor input provided by several small creeks (FWS EIS Chapter 3, 2006). Surface water flow is west towards San Diego Bay.

Tidal fluctuations within the Sweetwater Marsh range within a single cycle from a low of -2.0 feet msl to +4.0 feet msl for a total of approximately 6.0 feet of daily change (Philip Williams & Assoc., 1995).

4.3 Geology and Hydrogeology

Gunpowder Point consists of a combination of Bay Point Formation, which outcrops at Gunpowder Point, and Quaternary alluvium consisting of unconsolidated stream deposits of sandy silt, sand, and cobbles. Gunpowder Point is situated on the westerly-sloping Nestor Terrace, one of a series of well-defined wave-cut abrasion terraces created during the Pleistocene glacial episodes (Keller 1991 in FWS EIS Chapter 3). The Pliocene San Diego Formation, which underlies the Bay Point Formation, is the primary regional groundwater aquifer in the region. The San Diego Formation is slightly to moderately consolidated and characterized by a

OU 2 001587


wide range of sediments textures, including clay to gravel, and well-sorted medium to coarse sand, silty sand, and clayey sand (California Department of Water Resources, 2003).

Soil types along the coastal wetland areas of the Sweetwater Marsh Unit (MU) and Gunpowder Point are mapped as tidal flats. Soil components in upland areas at Gunpowder Point are mapped as Huerhuero Loam at 2 to 9 percent slopes (USDA, 2010).

Based on the results of drilling conducted at the Site (Geosyntec, 2010; Alisto, 2009), shallow geologic materials consisted primarily of silty clay to sandy silt from ground surface to depths of approximately 7 feet below ground surface (bgs). From approximately 7 to 16 feet bgs (the maximum depth investigated), coarser sandy silt to silty sand to poorly graded sand material was typically encountered, with some fining of materials below about 10 to 11 feet bgs in many boreholes.

Groundwater was encountered or indicated (wet core) in most Site borings at depths of about 8 to 12 feet bgs. Based on the proximity of the Site to the San Diego Bay and adjacent marshes, there is expected to be substantial hydraulic communication between the bay and marshes, with tidal influence on groundwater levels near the margins. The groundwater flow direction beneath the Site cannot be evaluated using the existing monitoring well network.

Gunpowder Point lies within the Lower Sweetwater Hydrologic Area (HA) of the Sweetwater Hydrologic Unit (HU). Beneficial use designations do not apply for groundwater in the Lower Sweetwater HA west of the Interstate Highway 5 (SDRWQCB, 2007). Therefore, no existing or potential beneficial uses are designated for groundwater beneath the Site.

5. PREVIOUS STUDIES

5.1 Areas of Concern

Features of interests were described in detail in the PA/SI; many of these features have been brought forward to the EE/CA as areas of concern (AOCs) based on former industrial uses and chemical use/production (Figure 2). Previous investigations completed by FWS evaluated many of the AOCs, in particular the vault study completed in 2008 (FWS 2007; GeoEngineers, 2007) and the 30-acre study completed in 2009 (FWS, 2009). AOCs and associated potential contaminants of concern are summarized in Table 1.

Several environmental investigations were completed from 1989 to 2006 to evaluate former surface features related to historical uses (vaults, concrete structures); however, these investigations provided limited solids (soil, sediment, groundwater) sampling and geophysical studies. Subsurface investigations were completed in 2008 through 2011 and included soil and groundwater sampling. Analytical results for soil and groundwater data were compared against preliminary human health and ecological screening criteria and are discussed in more detail in Section 6. A summary of previous studies at the Site is provided in Table 2. Previous soil and

OU 2 001588


sediment sample locations are shown on Figure 3a, and groundwater sample locations are shown on Figure 3b. Sediment samples are grouped with soil sample results in this work plan.

5.2 Soil Data Summary

In 2007 and 2008, approximately 39 soil samples were obtained by the FWS as part of a surface vault investigation from 23 soil borings advanced at locations surrounding the vault (Figure 3a). Water and sediment that had accumulated in the vault were also collected. Samples were analyzed for aliphatic hydrocarbons (alkanes), semivolatile organic compounds (SVOCs), nitroaromatics, metals, and perchlorate.

In April and November 2009, surface and subsurface soil samples were obtained from the Site that encompassed approximately 30 acres historically occupied by industrial facilities (Figure 3a). The purpose of the two soil investigations was to identify potential contamination sources through records searches and confirm the presence or absence of contaminants via sampling. Thirty borings (GPP-1 through GPP-30) were completed in April 2009 and 19 borings (GPP-31 through GPP-51; boring numbering was not consecutive) were completed in November 2009. Soil samples were obtained at surface (0-48 inches bgs) and subsurface (48-120 inches bgs) depth intervals. Soil samples were tested for a range of constituents based on historical site usage, including one or more of the following analyte groups: aliphatic hydrocarbons (alkanes), nitroaromatics, SVOCs as polycyclic aromatic hydrocarbons (PAHs), metals, perchlorate, herbicides, organochlorine pesticides, organophosphorous pesticides, and polychlorinated biphenyls (PCBs).

5.3 Soil Results Summary

Analytical results from soil testing completed during the 2007, 2008, and 2009 site investigations are summarized below and presented in Table 3.

• Aliphatic hydrocarbons were not detected in soil samples, with the exception for two compounds (n-tritriacontane and n-hentriacontane) detected at concentrations within one order of magnitude of the method reporting limits. Screening levels for these compounds were not available.

• Nitroaromatics were not detected in the soil samples tested.

• SVOCs were detected infrequently in soil samples, although dimethyl phthalate, benzo(g,h,i)perylene, and dibenz(a,h)anthracene were present at concentrations above the EPA human health risk-based screening levels. Pentachlorophenol, although analyzed as part of the herbicide method, was also analyzed as part of the SVOC method and was detected in soil samples across the Site at concentrations greater than the EPA human health risk-based screening levels.

• Metals were detected in soil samples across the Site. Concentrations of certain metals appear elevated when compared to statewide metals background concentrations

OU 2 001589


(Bradford et al, 1996); particularly arsenic, barium, boron, cadmium, copper, iron, lead, mercury, potassium, selenium, and zinc. Metals concentrations generally decreased with depth, with the exception of iron, vanadium, zinc, and to a lesser extent, copper, where metals concentrations appeared evenly distributed with depth. Concentrations of select metals with depth and sample locations are shown on charts presented in Appendix A.

• Perchlorate was detected in surface and subsurface soil samples across the Site. Perchlorate concentrations compared with depth and distribution across the Site are included in Appendix A.

• Herbicides and pesticides were detected in soil samples across the Site. Herbicide and pesticide concentrations generally decrease with depth. However, since these samples were obtained from the former agricultural area, they were determined to be consistent with historic agricultural uses of that portion of the Site and therefore, FWS does not consider the herbicides and pesticides detected in soil as indicative of a hazardous substance release (FWS, 2011). These constituents have not been carried forward as a COPC.

• One PCB Aroclor (1248) was detected at one location, GPP-01 from 0-48 inches bgs. The deeper sample at location GPP-01 was not tested for PCBs. Although the method reporting limits were greater than the most stringent screening criteria, these criteria are based on protection of groundwater as drinking water. Site groundwater will not be used for drinking water (CA RWQCB, 2007), and the method reporting limits (MRLs) do not exceed the next most stringent screening criteria (residential soil). The PCB detection at GPP-01 does not exceed the residential screening criteria for soil. PCBs were not detected in the other soil samples tested.

5.1 Groundwater Data Summary

Groundwater samples were obtained in April 2009 at seven borings (GPP-3, -4, -11, -16, -18, -21, and -22) and during the November 2009 investigation at five borings (GPP-10A, -13A, -18A, and -22A) (Figure 3b). Groundwater samples were tested for a range of constituents based on historical site usage, including nitroaromatics, SVOCs, metals, perchlorate, and VOCs. Four monitoring wells were installed in autumn 2010 to confirm perchlorate concentrations in groundwater grab samples obtained from temporary borings. Groundwater samples obtained in autumn 2010 and spring 2011 were tested for metals and perchlorate.

5.1 Groundwater Results Summary

Analytical results from groundwater testing completed during the 2009, 2010, and 2011 site investigations are summarized below and are presented in Table 4.

• Nitroaromatics were not detected in the groundwater samples tested.

OU 2 001590


• SVOCs generally were not detected in the groundwater samples, with the exception of bis(2-ethylhexyl)phthalate (BEHP) which was detected at very low concentrations in two borings near the vault.

• Metals (except mercury) were detected in groundwater, and several metals, including aluminum, arsenic, barium, beryllium, cadmium, chromium, copper, iron, lead, manganese, nickel, and vanadium, exceeded the primary EPA maximum contaminant levels (MCLs) and EPA risk-based human health screening levels.

• Perchlorate was detected in the groundwater samples at several of the borings completed in 2009 and at three of the four monitoring wells installed in 2010.

• VOCs were detected in groundwater samples and included acetone, benzene, ethylbenzene, m,p-xylenes, tetrachloroethene, and toluene. Of those VOCs, only benzene and tetrachloroethene were detected above the primary MCLs or EPA risk-based human health screening levels for the soil leaching to groundwater pathway

• Nitrates were detected in groundwater at concentrations greater than the MCL.

6. PRELIMINARY SCREENING LEVELS

Screening levels for soil and groundwater were compiled for human health and ecological exposure scenarios and presented in the 2011 FWS PA/SI report. Screening levels were compiled from the following sources, which are summarized in Tables 5a and 5b:

1. Soil:

• California Human Health Screening Levels (CHHSLs) (CAL-EPA, 2005),

• EPA Regional Screening Levels (RSLs) (EPA, 2011),

• San Francisco Bay Regional Water Quality Control Board Environmental Screening Levels (ESLs) (SFBRWQCB, 2007), and

• EPA Ecological Soil Screening Levels (ECO-SSLs) (EPA, 2005a - 2005f and 2007a - 2007h).

• California and Federal hazardous waste criteria (22CCR 2008 and 40CFR261.24).

2. Groundwater:

• EPA Regional Screening Levels (RSLs) (EPA 2011),

• California inland and marine waters (Cal Toxics Rule and Cal Ocean Plan) (EPA 2000 and California SWRCB 2001), and

OU 2 001591


• EPA MCLs and secondary drinking water standards (SDWSs) (EPA 2006), and

• California primary and secondary MCLs (22CCR 2008).

Soil, sediment, and groundwater results were screened against the most stringent screening criteria from applicable human health and ecological screening levels to evaluate potential data gaps existing at the Site. Screening levels for soil and groundwater are summarized in Tables 5a and 5b. Soil and groundwater exceedances for applicable screening levels by analyte group are shown on Figures 4a through4e and 5a through 5f, respectively.

7. SOIL AND GROUNDWATER DATA GAPS

Data gaps were identified with respect to soil depths, groundwater, and sediment sample locations based on the distribution of previous sampling locations and analytical testing. AOCs were developed in the PA/SI based on historical Site uses and features from the historical uses that remain at the Site. Data gaps were identified based on an evaluation of subsurface data collected per AOC (Table 1), the completeness of analyte testing, and sample depths.

7.1 Soil Data Gaps

Soil data gaps are as follows:

• Metals were tested at each soil and sediment sample location collected during the 2009 sampling events. Metals concentrations exceeded the most stringent screening criteria at each sample location, and arsenic, barium, boron, cadmium, copper, iron, lead, mercury, potassium, selenium, and zinc were greater than the median background soil concentration. Regional or site-specific background concentrations for these metals have not been determined.

As stated in Section 5.3, metals concentrations generally decreased with depth, with the exception of iron, vanadium, zinc, and to a lesser extent, copper. Concentrations of these metals appeared evenly distributed with depth (Appendix A).

Borings where metals concentrations did not decrease with depth, or where deeper samples were not obtained, included the following:

o Arsenic: GPP, -07, -08, -09, -10/10A, -14, -18/18A, -49, and -50

o Barium: GPP-40

o Boron: GPP-8, -10A, -18A, and -51

o Cadmium: GPP-08, -09, -22A, 38, -40, and -51

o Copper: GPP-19 and GPP-40

o Lead: GPP-40

OU 2 001592


o Mercury: GPP-21

o Selenium: GPP-40

o Zinc: GPP-07 and GPP-40

o Deeper (e.g. greater than 48 inches) samples were not obtained at all locations in AOCs 3, 4, and 5 (Vault Area), but were collected at several borings within these AOCs.

• Perchlorate concentrations in soil were widely distributed and concentrations generally decreased with depth (Appendix A).

• VOCs have not been tested in soil. However, VOCs exceed the most stringent screening criteria in groundwater at borings GPP-10, -44, -46, and -51. The source(s) of VOCs is currently unknown.

• Of the SVOCs analyzed, concentrations of PAHs (benzo(g,h,i)perylene, indendo(c,d)pyrene, and dibenz(a,h)anthracene) exceeded the most stringent screening criteria at numerous locations. PAHs were detected sporadically across the Site and at concentrations exceeding the screening criteria at borings:

o GPP-04 and GPP-06

o Vault Area boring W-3; however, PAHs were not detected in surrounding samples.

• Dioxins/furans have not been tested at the Site in soil; evaluation of these constituents may be warranted based on historic Site usage.

• Nitrates have not been tested in soil. However, concentrations exceed most stringent screening criteria in groundwater at borings GPP-13A, -44, -45, and -49. The source of nitrates in groundwater is currently unknown.

7.2 Groundwater Data Gaps

Groundwater data gaps are as follows:

• There are currently four monitoring wells at the approximately 30 acre Site. Additional groundwater monitoring wells are needed to provide adequate spatial coverage to evaluate groundwater occurrence and flow directions.

• Spatial distribution and background concentrations of metals and perchlorate in groundwater are not well defined. Groundwater analytical testing to date has been limited to metals and perchlorate at the four existing on-site monitoring wells; data gaps with respect to testing for additional parameters are discussed below. Association of metals and their potential correspondence with suspended solids should be evaluated.

OU 2 001593


• SVOCs, including PAHs, were detected in two groundwater samples from temporary borings located near a vault located in the north-central portion of the Site, in addition to a liquid sample from the inside of the vault. Other than the vault area, SVOCs were not detected in groundwater obtained from the temporary borings. However, the method reporting limits for some SVOCs, including PAHs, are greater than the groundwater screening levels. Additional testing for these constituents from site monitoring wells and potential new monitoring wells (see first bullet above) may be needed to support the human health and ecological risk assessments and/or EE/CA.

• VOCs have been detected in groundwater samples collected from temporary borings at concentrations exceeding the screening criteria. These VOC exceedances were observed at two locations in the northeastern portion of the Site and one location in the western portion of the Site. Groundwater samples from the four onsite monitoring wells have not been analyzed Site-wide for VOCs, and VOC concentrations in groundwater are a recognized data gap.

• Nitrate concentrations in groundwater samples have exceeded the most stringent criteria; however, the sources for nitrates in groundwater have not been identified to date. It is unknown whether the nitrate concentrations observed in groundwater are associated with past industrial operations at the Site or reflect naturally occurring conditions in groundwater.

8. SUPPLEMENTAL SITE INVESTIGATION

The sampling objective for this supplemental site investigation is to resolve the identified data gaps by obtaining Site-specific soil and groundwater data. In addition to the supplemental soil and groundwater sampling, surface water samples will be collected to evaluate the potential soil and groundwater to surface water pathways to mitigate for potential risks to aquatic receptors. Surface water sampling is proposed as a phased approach and will not be collected until the soil and groundwater data are evaluated. AOCs identified in the PA/SI have been preserved for discussion, as referenced in Table 6, Proposed Sample Locations and Rationale.

8.1 Data Use Objectives

The proposed sampling program is designed to meet the project objectives which include collecting sufficient data to evaluate the nature and extent of contaminants of potential concern (COPCs) in soil and groundwater, and potential pathways and risks to both human and ecological receptors. Data will also be collected to determine the background concentrations of metals and perchlorate for the Site, and to round out analytical testing suites and depths in the AOCs that were identified as data gaps. Once data gaps are resolved, the comprehensive soil, groundwater, and surface water data set for the Site will be used to determine potential human

OU 2 001594


health and ecological risk and to guide the evaluation of appropriate remediation actions, if necessary, to mitigate for any identified risk.

9. SUBSURFACE INVESTIGATION

The supplemental site investigation will collect data to evaluate potential impacts to human or ecological receptors, and to evaluate potential mitigation options. Proposed boring locations are shown on Figure 6 and the proposed sampling rationale is presented in Table 6.

Cultural resources monitoring will be required during the subsurface investigation, and will be performed by Laguna Mountain Environmental, Inc. (Laguna Mountain). Laguna Mountain, under subcontract to Geosyntec, will document the results of the monitoring program and, if necessary, record (on the appropriate California Department of Parks and Recreation forms - DPR 523 A/B) any significant or potentially significant resources encountered during the sampling program and notify the South Coastal Information Center at San Diego State University. If Laguna Mountain encounters anything of significance, work will be stopped at that location, consult with FWS about the potential finding, and the team will move to another sampling location.

9.1 Pre-Field Activities

Prior to performing the subsurface investigation at the Site, Underground Service Alert (USA) will be contacted at least 48-hours prior to initiation of sampling. Proposed intrusive sample locations at the Site will be clearly marked by Geosyntec prior to contacting the USA. A site-specific Health and Safety Plan (HASP) will be prepared for use by Geosyntec during the course of the field activities described herein (Appendix B).

9.2 Soil, Groundwater, and Surface Water Sampling

General soil, groundwater, and surface water sampling procedures are presented in the following sections, and specific sampling procedures are discussed in more detail in the Field Sampling Plan (FSP) (Appendix C). Field activities will be phased with subsequent activities contingent upon results from the first round of soil and groundwater sampling.

9.2.1 Soil

Approximately 20 soil borings will be advanced to approximately 15 feet bgs, to refusal, or groundwater, whichever is encountered first. Soil borings will be continuously sampled from the surface to the target depth for field screening, logging soil types, and to obtain samples for chemical analytical testing. Soil borings will be advanced using a truck-mounted direct-push drilling rig. Soil samples will be collected for laboratory analysis based on the results of field screening and at locations and depths summarized in Table 6. Analytical testing will be

OU 2 001595


completed as indicated in Table 6 and discussed in the Quality Assurance Project Plan (QAPP) in Appendix D.

9.2.2 Groundwater

Based on the soil boring data, up to two additional groundwater monitoring wells will be installed. The groundwater wells will be located to facilitate determination of groundwater flow direction and gradients. The four existing and the two new monitoring wells will be monitored and sampled to evaluate groundwater flow direction and gradient, and to resolve data daps identified above for groundwater. Field sampling methods for the collection of groundwater are described in the FSP. Analytical testing will be completed as shown in Table 6 and discussed in the QAPP in Appendix D.

9.2.3 Surface Water

Surface water samples will be obtained following the transducer study (Section 9.4) and upon receipt of soil and groundwater analytical results. Surface water samples will be obtained from four locations near (downgradient from) monitoring wells to evaluate the groundwater-to-surface water pathway where perchlorate, metals, and VOCs exceed the preliminary screening levels. Exact surface water sampling locations will be determined based on the analytical results, groundwater flow directions and elevations (which will indicate potential flux to surface water), and/or other features of interest.

9.3 Groundwater Monitoring Well Installation

Two additional wells will be installed to further characterize groundwater and provide data to evaluate the direction of groundwater flow. Following installation, the four existing and two newly installed wells will be surveyed by a licensed surveyor, under subcontract to Geosyntec.

Monitoring well locations will be determined following direct-push borings, and will be sited to provide adequate site coverage for determining groundwater flow directions and gradients in addition to chemical analytical data.

Monitoring well construction details are provided in the FSP (Appendix C).

9.4 Transducer Study

Pressure transducers will be placed in four of the six groundwater monitoring wells for approximately two weeks. Water level pressure transducers (Solinst™ Gold “level-loggers”) will be used along with a barometric pressure logger (“baro-logger”) placed in one well (to be determined) above the water level to monitor barometric pressure fluctuations during the study period. Groundwater elevations will be corrected for variations in atmospheric barometric pressure.

OU 2 001596


Data obtained from the transducers will be used for evaluating groundwater levels and groundwater flow directions. Data obtained from the transducers also will be compared to publically available NOAA tide information (#9410170 for San Diego, CA) and used to analyze the relationship between on-site groundwater and the surrounding surface water.

10. REPORTING

The investigation results will be reported to FWS in a technical memorandum that will be used to support the development of the EE/CA report. Using the data collected during this investigation and those collected in previous studies, Geosyntec will complete a Tier 1 Human and Ecological Risk Assessment in accordance with the Interim Final “Screening for Environmental Concerns at Sites with Contaminated Soil and Groundwater”, California Regional Water Quality Control Board, San Francisco Bay Region, November 2007 (Revised May 2008). Analytical data will be compared to screening levels for the Site to assess the need for additional site investigation (other than that proposed herein), remedial action, or a more detailed risk assessment.

The Health & Safety Inspection Checklist records should be kept on file at the project site. The requirement for periodic inspections is:

Not Applicable Applicable, and the frequency shall be:

Weekly Bi-Weekly Monthly 8. HAZARD ANALYSIS AND MITIGATORS Site specific hazards have been identified through a hazard analysis. Hazard analysis included a review of chemical, physical, and biological hazards. The analysis also identified health and safety hazard mitigators needed to protect workers, which are presented in Appendix C. 8.1 Chemical Hazards Potential exposure pathways to chemical health hazard agents include inhalation, dermal exposure, and/or ingestion. To effectively manage risk to exposure, constituents of concern (COCs) have been identified. Potential exposure to these COCs will be mitigated through engineering, administrative, and/or PPE controls. The COCs are documented and/or suspected materials present based on previous operations/activities. The identified COCs for this project are listed in Appendix D with appropriate hazard information, including signs of exposure. Hazard Mitigators, which include control measures and methods to minimize exposure, are presented in Appendix C. Also, airborne levels of COCs may be estimated or measured to evaluate levels of PPE that will be required for individual tasks. The type(s) of air monitoring to be performed are discussed in Section 9.

OU 2 001722


8.2 Physical Hazards Physical hazards due to the tasks to be performed (e.g., electrocution due to drilling, etc.) and due to the site setting and condition (e.g., slips, trips, or falls due to rocky terrain, etc.) were analyzed. Hazard mitigators for each physical hazard identified are presented in Appendix C. These hazard mitigators must be implemented for each task in which they are applicable, as summarized in the table in Appendix C. 8.3 Biological Hazards Biological hazards (e.g., allergic reactions to poisonous plants or insects indigenous to the area, etc.) associated with tasks to be performed were analyzed. Hazard mitigators for each biological hazard identified are presented in Appendix C. These hazard mitigators must be implemented for each task in which they are applicable, as summarized in the table in Appendix C. 9. AIR MONITORING APPLIES TO TASK: Not Applicable

Air monitoring will be performed to evaluate airborne exposure levels associated with the COCs on site within the breathing zone of site workers. Hazardous conditions may include concentrations that may cause acute or chronic illness, potential oxygen deficient environments, or potential explosive environments. Air monitoring may also be performed to evaluate the adequacy of engineering, administrative, and/or PPE controls. Air monitoring may be “real-time” (e.g., the instrument provides immediate results at the project), using multi-gas meters, photoionization detectors (PIDs), or colorimetric tubes. “Non-real-time” monitoring may also be performed by collecting samples and forwarding to a laboratory for analysis and quantification. The type(s) of air monitoring equipment required to evaluate COCs is outlined in Appendix E. Monitoring equipment must be calibrated based on the manufacturer’s requirements. Calibration results and air monitoring measurements must be documented. Based on the results noted and site activities or scope of work changes, the frequency of air monitoring may be adjusted on site by the SHSO with the consent of the Project Manager and communication with the EHSC.

OU 2 001723


10. PERSONAL PROTECTIVE EQUIPMENT The levels of PPE required for each task are presented in Appendix F. Required equipment and types of protective clothing materials, as well as an indication of the initial level of protection to be utilized, are listed. The level of protection may be upgraded or downgraded by the SHSO according to mitigation measures required in Appendix C or according to action guidelines provided in Appendix E. The PPE levels that are implemented must be documented in a daily field log. If respirators are worn, workers must abide by the company’s Respiratory Protection Program in accordance with 29 CFR §1910.134. Table 2 provides a record of the last fit test for each site worker that may be required to wear a respirator. Fit tests are valid for a period of one year. Persons with facial hair that may interfere with the respirator seal may not wear respirators. 11. DECONTAMINATION The SHSO and Project Manager will determine the type and level of decontamination procedures for both personnel and equipment based on evaluation of specific work activities in the controlled work zones. In an emergency, the primary concern is to prevent the loss of life or serious injury to personnel. Medical treatment will take precedence over decontamination in the event of a life threatening and/or serious injury/illness. Personnel will perform decontamination in designated and identified areas upon leaving “hot zones” where the potential exists for exposure to hazardous chemical, biological, or environmental conditions. Decontamination of personnel in Level D (modified) will consist of closure and disposal of coveralls, disposable boots, and gloves, (if applicable). Decontamination of personnel in Level C, if applicable, will consist, at a minimum, of: • Removal and cleaning/disposal of boot covers, coveralls, and outer gloves;

• Removal, cleaning, and storage of respiratory protection;

• Washing of boots or other non-disposable PPE (e.g., hard hat, safety glasses/goggles, etc.) suspected of being contaminated using a soap solution followed by a water rinse; and

• Removal and disposal of inner gloves.

OU 2 001724


Wash solutions and PPE may require disposal at a licensed waste facility. Hand tools and sampling equipment shall be decontaminated as needed by washing in decontamination basins with appropriate solutions, or, if possible, by dry decontamination. 12. EMERGENCY PREPAREDNESS AND RESPONSE A table presenting a list of contacts and telephone numbers for the applicable local off-site emergency responders is provided inside the front cover of this HASP (after figures). If the nature of the site work and COCs requires that off-site responders be notified before work begins on this project, the date that the pre-notification was made is presented in the table. The following emergency response equipment is required for this project: First Aid Kit Fire Extinguisher (Type ABC) Eyewash bottle Other: In the event of an injury to an employee, the Instructions for Injury Response, located in the front of this HASP, must be implemented immediately. ‘Tear-out’ forms are located after the Instructions for Injury Response. If professional medical attention is required, these forms must be provided to the medical provider at the time the medical attention is administered. Injury reporting is required per the procedures presented on the Instructions for Incident Reporting, also located in the front of this HASP. In the event that an emergency develops, the procedures delineated in the Emergency Response Procedures, located in the front of this HASP, are to be followed immediately. (Note that an emergency does not necessarily include an injury.) After the emergency is resolved, post-incident reporting is required per the procedures presented on the Instructions for Incident Reporting, also located in the front of this HASP. 13. CONFINED SPACE ENTRY

APPLICABLE NOT APPLICABLE The task(s) for this project involve confined-space entry. Workers must abide by the company’s Confined Space Entry Program [29 CFR §1910.120(j)].

OU 2 001725


14. SPILL CONTAINMENT

APPLICABLE NOT APPLICABLE The task(s) for this project involve handling of drums and/or containers that contain stored chemicals and/or wastes associated with sampling, excavation, transportation, etc. Workers must implement the hazard mitigating procedures for drum/container handling presented in Appendix C. 15.

General Safe Work Practices

• Minimize contact with impacted materials. Do not place equipment on the ground. Do not sit or kneel on potentially contaminated surfaces.

• Smoking, eating, or drinking after entering the work zone and before decontamination is not allowed. Employees who are suspected of being under the influence of illegal drugs or alcohol will be removed from the site. Workers taking prescribed medication that may cause drowsiness shall not operate heavy equipment and are prohibited from performing tasks where Level C or B personal protective equipment is required.

• Practice good housekeeping. Keep everything orderly and out of potentially harmful situations.

• Use of contact lenses may not be allowed under certain hazardous working conditions.

• The following conditions must be observed when operating a motor vehicle.

− Wearing of seat belts is mandatory

− The use of headlights is mandatory during periods of rain, fog, or other adverse weather conditions

− A backup warning system or use of vehicle horn is mandatory when the vehicle is engaged in a backward motion

− All posted traffic signs and directions from flagmen must be observed

− Equipment and/or samples transported in vehicles must be secured from movement

− The use of vehicles acquired by Geosyntec by non-Geosyntec personnel is prohibited

• In an unknown situation, always assume the worst reasonable conditions

• Be observant of your immediate surroundings and the surroundings of others. It is a team effort to notice and warn of dangerous situations. Withdrawal from a hazardous situation to reassess procedures is the preferred course of action.

• Conflicting situations may arise concerning safety requirements and working conditions. These must be addressed and resolved rapidly by the SHSO and PM to relieve any motivations or pressures to circumvent established safety policies.

• Unauthorized breaches of specified safety protocol must not be allowed. Workers unwilling or unable to comply with the established procedures must be discharged.

FIRE

• Know fire prevention procedures, fire-fighting techniques and essential precautions to prevent injury.

• Do not stop to get anything out of a building or area if evacuation is required. JUST GET OUT - and assemble in the predetermined evacuation assembly points.

• There are 3 elements to starting a fire: a fuel source, an oxygen source and a point of ignition.

• Know how and when to use different types of fire extinguishers.

• Keep all fire extinguishers in workable condition and accessible at all times. Access to or visibility of extinguishers shall not be obstructed.

• Control static electricity (e.g., ground equipment)

• Remove only the minimum required supply of paints, solvents, or other flammables from storage. At no time shall the quantity removed exceed one day’s working supply.

• Do not allow combustible products of rubbish, waste or other residues to accumulate. Oil soaked rags and material subject to spontaneous combustion shall only be stored in non-combustible containers with self-closing lids.

• Do not store gasoline, flammable solvents, and liquids inside a building unless the structure has been approved for flammable storage containers. Only OSHA-approved storage cabinets shall be used for all flammable liquids, paints or solvents.

• Flammable liquids shall be stored in locations that will not interfere with evacuation of the area in case of a fire.

• Do not permit smoking, striking of matches, or other sources of ignition outside of designated “SMOKING” areas.

• Discard cigarette butts, matches or other similar materials in non-combustible containers.

SKIN ABSORPTION • Be aware of chemicals of concern that can directly injure (corrode, burn, dehydrate) the

skin or that can be absorbed into the bloodstream and subsequently transported to other organs from dust, liquid or vapor sources.

• Know that skin absorption is enhanced by abrasions, cuts, heat, and moisture.

• Do not wear contact lenses in contaminated atmospheres (since they may trap chemicals against the eye surface). The eye is particularly vulnerable because airborne chemicals can dissolve in its moist surface and be carried to the rest of the body through the bloodstream (capillaries are very close to the surface of the eye).

• Keep hands away from face.

• Minimize contact with liquid and solid chemicals.

OU 2 001734



• Wear protective clothing (e.g., suits and gloves) as specified by the Site Specific Health and Safety Plan.

COLD STRESS • Work in pairs to keep an eye on each other and watch for signs of cold stress.

• Wear layers of loose fitting clothing, including insulated coveralls, head covering, gloves and boots.

• Minimize wind chill effects by wearing a wind resistant outer shell.

• Minimize lengthy periods of outdoor activity. This may require additional shifts and taking frequent breaks to warm up.

• Provide warm shelter.

• Remain hydrated. There is a tendency not to drink as many fluids when temperature is cold.

• Be aware of the symptoms of cold stress and appropriate first aid measures. Because of the considerable danger to personnel, outdoor work should be suspended if the ambient temperature drops below 0°F or if the wind chill factor drops below -29°F.

Signs and symptoms:

Mild hypothermia

Shivering, lack of coordination, stumbling, fumbling hands, slurred speech, memory loss, pale and cold skin.

Moderate hypothermia

Shivering stops, unable to walk or stand, confused and irrational.

Severe hypothermia

Severe muscle stiffness, very sleepy or unconscious, ice cold skin.

Treatment:

Mild hypothermia

Move to warm area, stay active, remove wet clothes and replace with dry clothes or blankets, cover the head, drink warm (not hot) sugary drink.

Moderate hypothermia

Call for an ambulance, cover all extremities completely, Place very warm objects, such as hot packs or water bottles on the victim's head, neck, chest and groin and follow treatments for mild hypothermia.

Severe hypothermia

Call for an ambulance, treat the victim very gently, cover all extremities completely.

OU 2 001735



DRILLING (Including Indoor) • All members of the drilling crews shall be trained in the standard operating safety

features and procedures to be utilized during operation, inspection, and maintenance of the equipment.

• Wear hard hats, steel toed boots, hearing protection and safety glasses at all times when performing drilling operations.

• Conduct a survey, prior to bringing drilling equipment to the job site, to identify overhead electrical hazards, potential subsurface hazards, and terrain hazard. Once on site, before drilling equipment is moved, the travel route shall again be visually surveyed for overhead and terrain hazards. Document possible hazards and communicate them to the drilling crew.

• Use only drilling equipment equipped with two easily-accessible emergency shutdown devices, one for the operator and one for the helper. Shutdown devices should be tested at the beginning of each day.

• When appropriate use auger guides on hard surfaces.

• Verbally alert employees and visually ensure employees are clear from dangerous parts of equipment prior to starting or engaging equipment.

• Channel the discharge of drilling fluids away from the work area to prevent the ponding of water. Containerize drilling fluids with secondary containment if necessary and possible.

• Use hoists only for their designed intent. Hoists shall not be loaded beyond their rated capacity. Steps shall be taken to prevent two-blocking of hoists (the condition when the lower load block or hook assembly comes in contact with the upper load block, or when the load block comes in contact with the boom tip). Follow the equipment manufacturer's procedures if ropes become caught in, or objects are pulled into a cathead.

• Do not run or rotate drill rods through rod slipping devices. No more than 5 feet of drill rod column shall be hoisted above the top of the drill mast. Drill rod tool joints shall not be made up, tightened, or loosened while the rod column is supported by a rod slipping device.

• Control dust using dust suppression techniques.

• Clean augers, drill casing, or drill rod only when the rotating mechanism is in neutral and the pipe is stationary is stopped.

OU 2 001736



• Cap and flag open boreholes; open excavations shall be barricaded.

• Keep all hand tools used during drilling operations clean and in good working condition.

• Check fire extinguishers and notify all onsite personnel to their whereabouts.

• Check cables for frays and hydraulic hoses for leaks daily.

• In situations where ambient water level may be above top of well screen, during well construction, ensure that well casing is vented to prevent air pressure build-up in blank casing above screen.

DRUM AND CONTAINER HANDLING • Only trained personnel should open drums containing unknown materials.

• Bulging drums or containers are an indication of pressure build-up. Open all drums or bungs extremely slowly to determine the presence of vapors or pressure inside the drum. If the possibility of fire or explosion exists, a protective shield should be used and/or remote opening devices. Employees not directly involved with opening a container shall be kept a safe distance away.

• Use only drums and containers that meet the appropriate DOT, OSHA, and EPA regulations.

• Utilize drum/container handling equipment whenever possible. The equipment should have a sufficiently rated load capacity and should be able to operate smoothly on the available surface.

• Label and identify drums and containers when moved to the staging areas to safely identify and classify their contents. Segregate incompatible drums.

• Inspect the integrity of the drum container before moving. Any drum or container lacking integrity shall be placed within an over pack container.

• Staging areas require adequate escape routes. Staging area should provide secondary containment for all moved drums.

• Employees must be warned of the potential hazards associated with the contents of containers or drums prior to moving said containers or drums.

• Organize site operation to minimize the amount of drum or container movement. Have a clear view of the available pathway when moving drums. If needed, an additional person should be available to provide guidance.

• Never stand on drums or containers.

• Use non-sparking tools and appropriate grounding and bonding equipment.

• Appropriate fire extinguishing equipment must be onsite at all times during drum handling.

• Spill control equipment shall be onsite in areas where spills ruptures or leaks may occur.

OU 2 001737



ELECTROCUTION • Install adequate warning signs and barriers (in plain sight) in all areas where hazardous

electrical facilities exist.

• Use only heavy duty electrical cords that are not subjected to excessive bending, stretching, or kicking. All cords and wires shall be frequently inspected for signs of defects. Damaged or frayed electrical wires, cords, and plugs shall be immediately replaced by a qualified electrician or other properly trained personnel.

• Equip all portable extension cords with a non-conducting plug and/or another socket shell. All electrical cords shall be equipped with three-blade grounding type plugs.

• Do not permit overloading of electrical circuits at anytime. The replacement of fuses or circuit breakers with makeshift materials or over-capacity fuses is strictly prohibited.

• A minimum clearance of 20 feet (radius) will be maintained between heavy equipment (i.e., drill rig) and any overhead power lines, regardless of voltage.

• Before subsurface work, a utilities search for underground lines will occur and will be documented (if within 3 feet of marked underground utility, hand digging is required).

• Installation and maintenance of electrical facilities or equipment must only be performed by qualified and properly authorized personnel or electrical subcontractors. Apprentice personnel permitted to work on electrical equipment shall be under the supervision of a fully qualified electrician.

• Follow the company Lock-out/Tag-out procedures when applicable. Electrical equipment and lines shall always be considered “energized” until proven “de-energized”. Before beginning work, each electrical circuit shall be inspected, tested, and where possible, isolated from the power source. Extreme care shall be exercised as wires designed to operate at ground potential may become energized by faulty or inadequate connections.

• Do not wear rings, watches or metallic objects that could act as conductors when working with electrical circuits.

• Do not use metal ladders and un-insulated tools while working with electrical circuits and equipment.

• Protect electrical wires with suitable protective conduits or devices where they are exposed to possible damage.

• Connect grounding devices to a ground before contacting any conductor of a circuit. When grounding devices are removed, they shall be disconnected from the circuit before being disconnected from ground.

• The type of circuit shall determine the type of protective equipment required. Rubber gloves, sleeves, blankets, mats, and insulated platforms shall be used as required. Questions regarding PPE should be directed to the SHSO.

OU 2 001738



• Inspect all insulated protective equipment continuously for defects or damages. Any defective equipment shall be replaced before using.

• Establish and enforce testing schedules for insulation qualities for protective equipment. All users shall verify that equipment has been satisfactorily tested prior to use.

• Electricians shall be familiar with the National Electrical Code; state and local electric codes; OSHA standards, including 29 CFR 1926, Subpart K; and applicable sections of the National Fire Protection Association Codes.

• When working on energized circuits of 440 volts or higher, at least one qualified electrician and one other employee shall be present.

• Use only NEC approved grounding equipment as a ground for electrical equipment. Metal frames on electricity-powered equipment, electrical facilities, and transmission equipment shall be connected to the grounding system. Alternative grounding systems complying with applicable electrical codes may be used for temporary portable equipment.

EYE INJURY • Wear appropriate eye protection according to the task at hand.

HAZARD TYPE OF PROTECTION

• Apply anti-fog product to lens not previously treated.

• Minimize the amount of vapor or particulate matter generated, if possible.

• Avoid touching the face and eyes.

• Flush eyes with water for at least 15 minutes if chemicals do get into the eyes. If condition persists, seek medical attention.

OU 2 001739



• If dust or foreign objects are in your eyes, do not rub your eyes.

• If an object becomes embedded in the eye, do not attempt to remove. Lightly bandage your eyes, or both eyes, if possible and immediately seek medical attention.

• Do not wear contact lenses if chemical or dust hazard is present (e.g. decontamination or preservation chemicals used during sampling).

• Provide on-site training to workers before tasks at hand.

• If visitors enter area, stop work until they are properly protected.

HAND/FOOT INJURY • Wear protective gloves as required in the Health and Safety Plan. Gloves should be

chosen to suit the work being performed (e.g., chemical resistant gloves will be worn when handling chemicals or sampling for suspected chemicals).

• Steel-toed/steel-shanked safety boots must be worn whenever working around heavy objects (or as required by the HASP). Insulated and/or waterproof boots may also be warranted depending on weather conditions. Boots should be inspected periodically for signs of wear (e.g., cracks in rubber or along soles) and replaced as required.

• Durable footwear which provides adequate ankle support should be worn when working in rugged terrain.

• Use proper lifting techniques to avoid dropping heavy loads on hands and feet (refer to lifting heavy loads hazard mitigator)

• Be aware of moving machinery and heavy equipment in the work area and tuck away any loose clothing.

HEAVY EQUIPMENT

Working around Heavy Equipment (drilling rig, fork lifts, support vehicles)

• Yield to heavy equipment.

• Listen for warning signals on heavy equipment.

• Perform a visual inspection and walk around parked heavy equipment before moving to assure that equipment is in good condition and that there are no personnel on the ground that could be injured or objects that could be damaged by vehicle movement.

• Wear hearing protection if required.

• Wear traffic vests for increased visibility.

• Maintain eye contact with the heavy equipment operator when working near equipment.

• Be aware of changes in sound of equipment which may indicate a change in direction.

Heavy Equipment Operators

• Use hand rails and footholds when mounting and dismounting equipment,

• Brakes, steering, clutches and controls shall be tested.

OU 2 001740



• Pay attention to workers on the ground who may be in the path and provide warning prior to moving the equipment.

• Permit no one to ride on, or in, heavy equipment. This includes any portion of a backhoe, bulldozer, forklift or the back of a pickup truck, except in locations specifically designed for passenger use and approved by the SHSO.

• Keep haulage vehicles under positive control at all times while operating. Vehicles shall be kept in gear when descending grades.

• Do not use heavy equipment on slopes with steepness exceeding 3H:1V unless operations are consistent with manufacturer’s recommendations (if the Owner’s Manual is not with the equipment or does not specify slope operating procedures, see the SHSO).

• Operate equipment with booms, blades, buckets, beds, etc., lowered or in a stable position while on slopes. Safety cables tethered to appropriate anchors shall be used for equipment working on steep slopes, where appropriate.

• Suspend in slings or support by hoists or jacks heavy equipment in need of repair. The equipment must also be blocked or cribbed before working underneath.

• Shut off motors, do not allow smoking, and use proper dispensing equipment when refueling gasoline-operated equipment to prevent fire hazards.

• Lower hydraulic systems (e.g., blades, etc.) to the ground, set brakes, and shut down equipment if malfunction occurs.

• Use rollover protection and seat belts.

KNIVES / BLADES • Always wear proper protective equipment. This should include:

- heavy-duty leather gloves,

- steel-toed boots with non-slip soles, and

- hardhat and eye protection.

• Check the work area and make sure that:

- the ground is free of obstacles such as rocks, stumps, holes, and wet or otherwise slippery conditions.

- you can get a firm footing on the ground.

• Route cords, hoses, and cables supplying power to portable power tools to prevent tripping hazards.

• Protect tools from corrosion damage.

• Keep tools free of accumulated dirt and unnecessary oil or grease.

• Worn, damaged or dull blades should be sharpened or replaced as necessary.

OU 2 001741



LIFTING HEAVY LOADS • Proper lifting techniques include:

− Feet - Feet should be parted, with one foot alongside the object being lifted and one behind. Feet should be comfortably spread to give greater stability. The rear foot should be in position for the upward thrust of the lift.

− Back - Use the sit-down position and keep the back straight, but remember that “straight” does not mean “vertical”. A straight back keeps the spine, back muscles, and organs of the body in correct alignment. It minimizes the compression of the abdomen that can cause a hernia.

− Arms and Elbows - The load should be drawn close to the body, and the arms and elbows should be tucked in. When the arms are held away from the body, they lose much of their strength and power. Keeping the arms tucked in also helps keep body weight centered.

− Palm - The palm grip is one of the most important elements of lifting. The fingers and the hand are extended around the object to be lifted. Use the full palm; fingers alone have very little power.

− Chin - Tuck in the chin so the neck and head continue the straight back line. Keep the spine straight and firm.

− Body Weight - Position the body so its weight is centered over the feet. This provides a more powerful line of thrust and assures better balance. Start the lift with a thrust of the rear foot. Shift hand positions so the object can be boosted after knees are bent. Straighten knees as object is lifted or shifted to the shoulders. To change direction, lift the object to a carrying position, and turn the entire body, including the feet. Do not twist your body. In repetitive work, both the person and the material should be positioned so that the worker will not have to twist his body when moving the material. If the object is too heavy to be handled by one person, get help.

• Limit continuous lifting of weights to 50 pounds or the maximum allowed by the client whichever is less. Lifts of heavier weights are permitted on an interim basis. Help shall be obtained for lifting of loads greater than 50 pounds or the maximum allowed by the client whichever is less. Mechanical equipment should be used on heavy materials when possible. If mechanical assistance is not available, adequate manpower to maintain the 50-pound limit per employee will be required.

• Do not lift more weight than can be handled comfortably, regardless of load weight. If necessary, help should be requested to lift a load so that the lifting is comfortable.

• Use drum dollies when moving drums or barrels.

• Inspect objects for grease or slippery substances before they are lifted to ensure that the object will not slip.

OU 2 001742



• Do not carry long, bulky or heavy objects without first verifying that the way is clear and that vision is unobstructed. This ensures that other persons or objects will not be struck by the load.

• Do not carry loads that cannot be seen over or around.

• Exercise caution when lifting above the chest level.

• Make sure workers are physically suited for the job before assigning jobs requiring heavy and/or frequent lifting. A person’s lifting ability is not necessarily indicated by his height or weight.

• Before lifting an object, consideration should be given to how the object will be set down without pinching or crushing hands or fingers. For example, to place an object on a bench or table, the object should be set on the edge and pushed far enough onto the support so it will not fall. The object can then be released gradually as it is set down, and pushed in place with the hands and body from in front of the object.

• When two or more people are handling the same object, one should “call the signals”. All the persons on the lift should know who this person is and should warn him if anyone in the crew is about to relax his grip.

LOUD NOISE • Wear hearing protection in areas with constant or loud noise.

• Know the effects of noise, including:

− Workers being startled, annoyed, or distracted.

− Physical damage to the ear, pain, and temporary and/or permanent hearing loss.

− Communication interference that may increase potential hazards due to the inability to warn of danger and proper safety precautions to be taken.

• Implement the company Hearing Conservation Program when noise exposures equal or exceed an 8-hour, time-weighted average (TWA) sound level of 85 decibels on the A-weighed scale (dB).

• Utilize feasible administrative or engineering controls if workers are subjected to noise exceeding an 8-hour TWA sound level of 90 dB.

SLIPS, TRIPS, AND FALLS • Wear the proper foot wear and clothing for the task at hand.

• Pay attention to the work environment and become aware of all equipment and vehicles active onsite and use caution when moving about.

• Use caution when walking on sloped areas (especially geosynthetics), particularly when moisture is present. Use caution when walking on soft or uneven surfaces; e.g., marsh areas. Watch for icy conditions in cold weather.

• Follow the established designated safe paths for travel and keep these areas free from debris. Avoid steep or slippery slopes and paths near operation vehicles and equipment.

OU 2 001743



• Follow good housekeeping procedures. Never assume that someone else will clean up a spill or put away an object.

• Remove or clearly mark objects that pose tripping hazards.

• Prevent water accumulation where practicable.

• Cables and/or wiring should be taped down, when possible. Locate cables and/or wiring out of the commonly used areas.

• Mark or repair any opening or hole in the floor.

• Carry objects in a manner that allows you to see in the area you are moving in. Do not carry objects that are too large or bulky. Do not carry more weight than you can balance and keep stable. Understand that PPE can reduce or limit your field of vision and mobility.

• Use the proper ladder for the task at hand and do not exceed the recommended height. Do not use the top two rungs of a ladder. Ensure a flat and stable footing for the placement of a ladder. Utilize the buddy system to help secure the ladder. When working over 6 ft., utilize fall prevention measures. Obey height and weight guidelines and/or rules.

• Use the handrail when using stairs. Be aware of stairway blockages.

• If conditions even slightly resemble an unsafe environment, do not make any assumptions that the integrity of a workplace is intact.

• Never jump over or into a trench or excavation.

• Walk, do not run.

• Maintain proper lighting so obstacles are clearly visible

UTILITY PROTECTION The occurrence of above and below-ground utilities should be anticipated at every site. The traditional method of using existing “as built” plans and maps (if available) and probing in the field (i.e., “hunt and hope”) is not sufficient to provide adequate assurance that utilities are not impacted during site activities. Geosyntec developed this Utility Protection Hazard Mitigator to implement prior to conducting intrusive site activities (i.e., drilling, well installation, trenching, excavation, hand auguring, etc.). The objective of the Utility Protection Hazard Mitigator is to describe the process necessary to investigate, and to the extent practical, identify utilities in work areas for the purpose of avoiding the utilities, protecting utilities and site personnel, and mitigating impacts to site operations.

Approximate location of subsurface installation means a strip of land not more than 24-inches on either side of the exterior surface of the subsurface installation.

Excavation means any operation in which earth, rock, or other material in the ground is moved, removed, or otherwise displaced by means of tools, equipment, or explosives in any of the following ways: grading, trenching, digging, ditching, drilling, auguring, tunneling, scraping, cable or pipe plowing and driving, or any other way.

High priority subsurface installation means high-pressure natural gas pipelines with normal operating pressures greater than 415 kPa gauge (60 psig) or greater than six inches nominal pipe

OU 2 001744



diameter, petroleum pipelines, pressurized sewage pipelines, high-voltage electric supply lines, conductors, or cables that have a potential to ground of greater than or equal to 60 kilovolt (kV), or hazardous materials pipelines that are potentially hazardous to workers or the public if damaged.

The Mitigator process is summarized below:

• Identify the location of the planned intrusive activities.

• Mark the planned work area with white water based marking paint. If work area is not visible from the street either because of obstruction or distance, provide distance from street to work area (i.e., 150 feet north).

• Contact DigAlert or dial 811 (nationwide) to identify utilities in your work area. http://www.digalert.org/ (811) provides a link to the local state operated “Call-Before-You-Dig” service.

• Review existing utility maps with facility personnel and determine the approximate numbers and types of utilities within the project area. This is inclusive of below-ground utilities that may be encountered during intrusive operations as well as overhead utilities that may be encountered during operations (i.e., drilling mast and overhead power lines).

• Most “Call-Before-You-Dig” services will only mark below-ground utilities leading to the site utility meter. With the exception of high priority utilities (as defined above), utilities present after passing through the site meter may be left without adequate inspection. In such cases, the use of a private utility location firm may be prudent to ensure thorough identification of utilities.

• Retain the services of a private utility locating company that can identify metallic utilities and anomalies in the vicinity of the work area. Private utility location firms use a variety of location techniques. The suspected types of utilities should be discussed with the private utility location firm to ensure that proper techniques are used. Improper techniques may result in missed or improperly identified utilities.

• DigAlert must be called at least 48 hours prior to the start of work to complete a utility inspection. (For example, if you notify DigAlert on Tuesday at 9:43 a.m. no work can begin until Thursday at 9:43 a.m.)

• Record the inspection confirmation number. Confirm that the inspection was conducted prior to the start of work. The inspection confirmation number is critical in the event that an unmarked utility is encountered, or if a utility identified during the inspection request did not mark the site for the presence or absence of the utility (no-show). If a no-show occurs with it may be possible that the utility operator sent a facsimile care of the project manager (identified during utility inspection request) indicating that there are no conflicts in the planned work area. However, if there is any question, contact DigAlert immediately and request that the missing utility please call to confirm presence or absence of utility in work area or schedule a meeting time at the site.

• After below-ground utilities are identified, the utilities should be marked. The most common marking method is paint or pin flags. The following marking colors are

OU 2 001745



generally widely accepted to demarcate specific types of utilities, but should be confirmed.

• Above-ground utilities should be visually identified. Warning signs may be placed in work areas to remind workers of the above-ground utilities. Other techniques such as shielding or utility relocation may be necessary to make the work safe. Proper set back and approach distances must be maintained at all times.

• Be observant of above-ground features at a site that may be indicative of an underground utility line. An example of this would be noticing two fire hydrants and noting that there is likely a buried water line between them, sings of trenching activities, asphalt or concrete patches, or linear depressions in the ground surface.

• Following the completion of the utility marking, the work area should be inspected by all members of the project team (client, engineer, and contractor) to inspect and discuss the finding. Adjustments to site operations, if necessary, should be discussed and agreed upon by the project team prior to initiation of site work. If possible, work areas should be re-located away from utilities.

• If conditions allow, consider using vacuum excavation.

• Depending on the proximity of utilities to the work area, low impact soil removal techniques (potholing) may be necessary to either confirm the presence of utilities or to provide protection of utilities before invasive activities. In such cases, hand excavation, hand auguring, vacuum excavation, water jet removal, or other low impact removal techniques may be necessary to a depth of 3 to 5 feet (or other depth as determined by project-specific conditions). In cases where a high priority utility is located within 10 feet of the work area, documentation from the utility owner must be obtained allowing potholing before any work can be conducted. If the utility is not found after potholing is conducted, contact DigAlert and the utility owner immediately to request additional information as to the location of the utility. It is necessary to conduct potholing activities before any work can be conducted in the vicinity (within 10 feet) of the high priority utility.

OU 2 001746



• If utility location markings are lost, damaged, or faded, a new utility location survey should be conducted to replace the missing or damaged markings. Please note that some municipalities require that all utility markings be removed after work is completed. Black spray paint may be used to cover up utility markings in the street but must be removed from sidewalks.

• In all cases, State, local, utility-specific requirements, facility-specific controls, permits, and operations should be considered and incorporated into the Utility Protection Hazard Mitigator.

• Utility protection should be addressed during each tailgate or job briefing in order to reinforce below-ground utility location and the avoidance of above-ground utilities.

DOGS • Never approach a stray dog.

• If a stray dog is at your site, stay in your vehicle.

• If a stray dog approaches, back away slowly and proceed to your vehicle or the closest secure building.

• If a vehicle or secure building is not close by when a stray dog approaches, stay calm. Do not run and do not yell. If you must say anything at all, use a calm, firm voice and avoid eye contact. Back away slowly from the dog or stand still until it turns away. Keep your hands firmly by your side.

• If a dog jumps, raise your knee to protect yourself.

• If a dog attacks, curl into a ball with your hands over your head and neck, and protect your face.

• Be aware of unusual dog behavior. Stray dogs may have rabies, which is exemplified by the following signs:

- Constant growling and barking

- Dilated pupils, disorientation

- Erratic behavior

- Facial expression showing anxiety and hyper-alertness

- Inability to swallow, leading to drooling and foaming of saliva (i.e., "foaming at the mouth")

• If bitten or scratched by a dog, seek medical attention immediately.

STINGING INSECTS / VERMIN / SNAKES • Be able to recognize stinging insects/vermin/snakes indigenous to the site location and

habitats. Learn the indigenous dangerous species (e.g., spiders, snakes, ticks) prior to entering the field and know the first aid treatments.

• Venomous snakes swim on top of the water, non-venomous snakes swim with only their heads above water.

OU 2 001747



• Advise the SHSO if you have allergies to any insects prior to engaging in any field activities.

• Include the following preventative measures as necessary: wear light-colored clothing, keep clothing buttoned, tuck pant legs into socks, keep shirt tails tucked in, boots, hoods, netting, gloves, masks, insect repellants or other personal protection.

• Snake bite kits are commercially available and should be carried by field personnel when working where venomous snakes exist. In the case of a snake bite, keep the patient calm, restrict activity and immobilize the bite area (do not elevate), and immediately obtain medical attention.

• Report any bites or stings to the SHSO and seek medical attention immediately.

• Be aware of potential hive/nest locations, which may include culverts, drainage pipes, junk piles, or dense shrubbery.

• Advise the SHSO if you are allergic to stinging insects prior to engaging in any field activities.

• Include the following controls:

− Do not agitate stinging insects or disrupt their hive/nest.

− Wear light-colored clothes.

− Avoid wearing perfumes, hair spray, or scented lotions in the wilderness.

• If attacked:

− Do not scream or wave arms.

− Cover your face with your hands.

− Run for shelter in a building or vehicle. Do not seek shelter in water.

− Remove stingers as quickly as possible to lessen the amount of venom entering the body. Remove the stinger by raking your fingernail across it. Don’t pinch or pull the stinger out. Put ice on the sting to reduce the swelling.

Report any stings to the SHSO and seek first aid or emergency medical care immediately if stung several times.

Perchlorate BMPs for Businesses Producing, Testing, or Developing Solid Rocket Motors

Businesses that process, manufacture, or store perchlorate materials, such as solid rocket motors, must contain these materi-als in a weather-resistant structure without drains and that prevent seepage into or out of the containment area.

On or before January 1, 2008 and every five years thereafter, a business usingsolid rocket motors in amounts greater than 8,000 pounds at any given time must submit to DTSC any existing environ-mental monitoring for perchlorate in the soil and/or water around the area of use.

Perchlorate BMPs for Businesses Using Fertilizer Containing Perchlorate

Businesses that manufacture, package, or distribute this fertilizer must ensure that products are properly labeled or marked with the following, “Perchlorate Material – special handling may apply.”

Businesses that simply use this fertilizer are exempt from labeling.

There are alternatives to using a label in the BMPs which include shipping docu-ments, MSDS, and training.

Businesses that handle or sell these fertil-izers need to ensure that these products are in durable and water-resistant packag-ing, containers, or are stored in weather –resistant structures.

Businesses that apply the fertilizer are ex-empt from the containment requirement, if the fertilizer is stored for less than 30 days on the site of intended application.

If the distributor from which you got it reported the fertilizer as required by the California’s Food and Agriculture annual tonnage report on fertilizer sales and dis-tribution, the business using it need not

make the one-time notification described elsewhere.

Fertilizers allowed by the U.S. Depart-ment of Food and Agriculture in keeping with the Organic Foods Production Act of 1990 and fertilizers derived from those sources are exempt from pollution pre-vention requirements.

8,000 pounds of solid rocket motors dur-ing any calendar year must submit to DTSC any existing environmental moni-toring for perchlorate in the soil or water around the area of use.

How do the perchlorate BMPs apply? Perchlorate BMPs for Households Households are subject to these regulations but have the following minimal requirements.

Households need to maintain proper packaging. The best way to do that is to keep perchlorate-containing materials in the original containers.

If you keep the materials in durable, wa-terproof packaging, you do not have to have a second or backup way to contain it.

If you use safety flares, keep the duration and number of flares to what is necessary to ensure safety.

If you use marine safety flares, do not throw them in the water or in the normal garbage. You cannot burn them as a way to dispose of them. Contact your local household hazardous waste center for di-rections on management.

Any spills of perchlorate products, spent fireworks, or spent model rockets need to be collected and may be disposed in the garbage.

Perchlorate BMPs for Businesses For all other businesses, the requirements depend on how the business uses or manages perchlorate materials and/or waste. The following highlight requirements for businesses that sell perchlorate-containing products or handle pyrotechnics, safety flares, solid rocket motors, or fertilizers:

Perchlorate BMPs for Retailers

Retailers who distribute perchlorate-containing materials for sale, resale or use in California are responsible to ensure

that products are properly labeled or marked with the following, “Perchlorate Material – special handling may apply.” There are alternatives to using a label in the BMPs which include shipping docu-ments, MSDS, and training.

Retailers need to ensure that perchlorate-containing products are in packaging or containers that are durable and water-resistant.

Perchlorate BMPs for Special Event Organizers or Amusement Parks using Fireworks

Pyrotechnics operators are responsible for collecting any “stars” and un-ignited py-rotechnic material found during the in-spection of the firing range after a public display of fireworks. The collected mate-rial must be managed as hazardous waste.

On or before January 1, 2008, a business that uses fireworks in amounts greater than 4,000 pounds of pyrotechnic compo-sition during any calendar year needs to submit to DTSC any existing environ-mental monitoring for perchlorate in the soil and/or water around the area of fire-work use.

Perchlorate BMPs for Law Enforcement, Fire Response and Other Governmental Agencies using Safety Flares

Agencies that use safety flares should limit the duration and number of flares as necessary to ensure safety.

All personnel who routinely use flares in the normal course of employment should receive instruction on the potential envi-ronmental hazards associated with the use of perchlorate materials and on the per-chlorate BMP requirements.

On or before January 1, 2008, and every five years thereafter, an agency that uses perchlorate-containing safety flares in an amount greater than 500 pounds in any month, needs to review the use of these perchlorate-containing products and de-termine for itself if a non-perchlorate- 5

OU 2 001757

One-Time Notification

Businesses managing more than 500 pounds of solid perchlorate material or 55 gallons of liquid perchlorate material at any one time must submit to DTSC a one-time notification about their perchlorate materials and related activities. Send that notification to DTSC on or before Sep-tember 1, 2007, to cover activities occur-ring between July 1, 2006 and June 30, 2007. This is in addition to the required hazardous material business plan. Certain exemptions may apply, see California Code of Regulations, title 22, section 67384.7(c).

Special Practices Use road safety flares in a way to mini-mize release of perchlorate into the envi-ronment. Businesses that use road flares should limit the duration and number of flares as necessary to ensure safety.

Road flares should be allowed to burn completely.

All personnel who routinely use road flares in the normal course of employ-ment should receive instruction on the po-tential environmental hazards associated with using perchlorate materials and on the perchlorate best management practice requirements.

Use marine safety flares in a manner that minimizes releases of perchlorate to the environment. Do not throw them into the water or into normal garbage. You cannot burn flares to dispose of them.

Collect un-ignited pyrotechnics within24 hours of a fireworks display andmanage them as hazardous waste.

Spill Response

Businesses are responsible for cleaning up any spills of perchlorate-containing mate-rials. You must first contain the spill, then clean it up to prevent the chemical from going into storm drains.

Discharge and Disposal

Businesses can only dispose of perchlo-rate-containing solid material to either a hazardous waste landfill or a composite-lined portion of a non-hazardous waste landfill.

Landfills and Publicly Owned Treatment Works (POTWs, wastewater treatment facilities owned by a state or municipal-ity) that accept non-hazardous perchlorate wastes must notify the appropriate Re-gional Water Quality Control Board of any perchlorate discharge and comply with any modifications to existing envi-ronmental monitoring programs.

Businesses that discharge non-hazardous liquid perchlorate-containing waste or wastewater must notify the overseeing regulatory agency of the discharge. Typi-cally, this is the POTW having jurisdic-tion in their area, and the business must notify the local Regional Water Quality Control Board. This allows regulatory agencies the opportunity to evaluate these discharges and determine whether the business should include perchlorate in its monitoring program.

Pollution Prevention

On or before January 1, 2008, and every five years thereafter, a business that uses perchlorate-containing fertilizers, safety flares, explosives, or blasting agents, in an amount greater than 500 pounds in any given month (the same “trigger” used in the Business plan) must review the use of these products determine for themselves if a non-perchlorate-containing alternative is available. These businesses also need to review and implement as appropriate pol-lution prevention measures to prevent re-leases of perchlorate. Certain exemptions may apply, see California Code of Regu-lations, title 22, section 67384.11(a).

On or before January 1, 2008, a business using fireworks with more than 4,000 pounds of pyrotechnic composition or 4

What are the human health effects ofperchlorate?Perchlorate exposure at certain levels can disrupt the function of the thyroid gland by interfering with the iodide uptake and thyroid hormone pro-duction. This interference may lead to develop-mental defects. Scientists consider pregnant women, children, infants, and individuals with thyroid disorders to be the populations most at risk of harm from being exposed to perchlorate. These health threats are the reason agencies set standards for perchlorate.

When do the perchlorate BMPs apply? Perchlorate materials include all forms of matter, goods, products, or waste that contain perchlo-rate. The perchlorate best management practices regulation specifically excludes hazardous waste, materials with perchlorate concentrations below6 parts per billion (ppb), food, crops, irrigation water, combustion residuals, and contaminated media.

The regulations apply to any person or business that manages perchlorate materials or waste in any manner including use, processing, genera-tion, transportation, storage, and disposal.

How can I determine the concentration of perchlorate?You may use industry or chemical knowledge, or a MSDS, to determine the perchlorate concentra-tion. You can also determine the concentration by using various analytical methods. To comply with the Safe Drinking Water Act standards, a lab must use EPA Method 314.0 - Determination of Perchlorate in Drinking Water by Ion Chroma-tography. U.S EPA and others are developing ad-ditional analytical methods. As examples, EPA’s Office of Solid Waste is working on a Method 6850 for analyzing perchlorate in various wastes; and the U.S. Food and Drug Administration pub-lished a draft analytical method for perchlorate in water, milk, and lettuce.

What are the Perchlorate Best Management Practices? DTSC established perchlorate best management practices in regulations to address various aspects of handling perchlorate-containing material to minimize the threat of release and resulting pub-lic health or environmental harm. Key require-ments of these regulations include:

Labeling

Businesses need to inform purchasers of perchlorate materials or products about the item’s perchlorate content.

Businesses that manufacture perchlorate materials, repackage perchlorate materi-als, distribute perchlorate materials for sale, receive perchlorate materials for re-sale or use in California, or who generate a perchlorate-containing waste need to ensure that these perchlorate materials are properly labeled or marked with the fol-lowing, “Perchlorate Material – special handling may apply.” There are alternatives to using a label in the BMPs which include shipping docu-ments, MSDS, and training.

Packaging

Businesses that manufacture, package and distribute perchlorate materials must en-sure they are properly contained in water-resistant packaging and labeled.

Containment

Businesses must adopt additional con-tainment procedures when materials or products are not contained in durable, wa-ter-resistant containers. For example, dur-ing manufacturing or repackaging, there may be times when perchlorate-containing material is not in a container – transferring from one container to an-other, for example - so that activity needs to be occur in weather-resistant structures on floors that do not contain drains.

OU 2 001759

attribute its presence in the environment to past waste handling practices at facilities that manu-facture or use this perchlorate and materials con-taining the chemical. It may also be present in the environment as a consequence of using perchlo-rate-containing products such as those identified below.

How is perchlorate used? Perchlorate is used primarily as an ingredient in solid rocket propellant. The Department of De-fense, the National Aeronautics and Space Ad-ministration (NASA), and the defense industry use, and have for decades used, perchlorate in manufacturing, testing, and firing rockets and missiles. On the basis of 1998 manufacturer data, U.S. EPA estimated that manufacturing demand for the military and NASA is 90 percent of the perchlorate salt produced in the United States.

Private industry has used perchlorate to manufac-ture products such as fireworks, flares, automo-bile airbags, coin-cell batteries, and commercial explosives. Perchlorate is also found as an impu-rity in manufactured chemicals and products. Perchlorate can also occur as an impurity in some natural minerals used in some fertilizers.

How do I know if I am using products that contain perchlorate? You can find perchlorate in a variety of materials. The new perchlorate regulations require that those who manufacture products, or who bring products into California for distribution, label those products to inform consumers of the per-chlorate content. The information may appear on the product itself, on the product label, in a Mate-rial Safety Data Sheet (MSDS), or on a product insert. A MSDS is a detailed informational docu-ment of a hazardous material. If the material al-ready has a perchlorate label, you can assume that the material contains perchlorate.

In what products can I expect to find perchlorate? Solid Rocket Motors: The amount of ammonium perchlorate required in a given motor varies by the type of solid rocket or missile propellant. For

example, model rockets are fueled by single-use rocket motors may contain perchlorate. These motors are professionally manufactured and available to the general public for purchase.

Flares: Both road and marine flares contain per-chlorate salts.

Fireworks: Sodium perchlorate and potassium perchlorate are often ingredients in fireworks.

Pyrotechnic Devices: Pyrotechnics, used to pro-duce light, smoke, heat, or sound effects, all con-tain an oxidizer component that is often a perchlorate material.

Explosives: Perchlorate salts have been used as detonators, initiators, and propellants in military explosives. A newer class of explosives now in-cludes ammonium perchlorate in the formulations to reduce accidental ignitions due to shock.

Blasting Agents: Some blasting agents, mostly water gels, and emulsions, can contain substantial amounts of perchlorate salts. Perchlorate-containing blasting agents are especially useful in construction and mining when conditions are wet or water-saturated.

Common Batteries: These include small button batteries which are the size and shape of coins. The battery numbers will start with “CR” and they may be found in watches, appliances, key-less entry systems, and any device that is able to retain memory after the power supply is cut off.

Air Bag Initiators: Airbag initiators are part of a car’s safety system and they may contain per-chlorate. If the air bag is deployed during an ac-cident, the perchlorate is used up in the process.

Bleach: Hypochlorite solutions may contain per-chlorate as an impurity. The concentration may increase as the product ages.

Fertilizers: Perchlorate has been found in meas-urable amounts as an impurity in some fertilizers made with natural minerals such as bloodmeal, certain nitrate, fishmeal, hanksite, kelp, and pot-ash. The fertilizer label and the MSDS should be reviewed to determine the presence of perchlorate in the fertilizer product.

OU 2 001760

INTRODUCTIONThe California Legislature passed the Perchlorate Contamination Prevention Act of 2003 requiring the Department of Toxic Substances Control (DTSC) to adopt best management practices regulations for perchlorate materials. DTSC adopted the Perchlorate Best Management Practices (BMP) regulations on December 31, 2005, and the regulations are effective July 1, 2006.

If you are in the Department of Defense, or you are in an industry centered on aero-space, fireworks, pyrotechnics, safety flares, amusement parks, automobile air bag and safety restraint, lithium perchlorate batteries, or if you are in a public safety agency, this information is of use to you. Others affected by these regulations include farmers who use perchlorate-containing fertilizer, laboratories, bleach manufacturers and users, and Publicly Owned Treatment Works (POTWs). Even households may be affected.

This fact sheet provides some background information to help understand the new regulations. This fact sheet also lists the types of perchlorate-containing products that may be subject to these requirements and describes the perchlorate best management practices.

Why regulate perchlorate? There are existing hazardous material regulations for perchlorate in its pure form be-cause it is used to enhance combustion. In recent years, environmental agencies have found more and more instances of perchlorate appearing in drinking water, ground-water, surface water and soil. In light of the risks to public health and the environ-ment posed by perchlorate releases, the California Legislature directed DTSC to establish best management practices for the prevention of perchlorate contamination. DTSC wrote regulations establishing standards for handling materials, products, and waste that contain perchlorate.

What is perchlorate? Perchlorate is a chemical that is both manufactured and naturally-occurring. Most commonly found as an ionic salt, when dissolved in water it easily moves through and travels with the flow of water on or beneath the ground. Ammonium perchlorate and sodium perchlorate are examples of manufactured salts. Environmental agencies

3. HAZARD IDENTIFICATION

EMERGENCY OVERVIEW: This product is a colorless, odorless gas. Releases of this product may produceoxygen-deficient atmospheres (especially in confined spaces or other poorly-ventilated environments);individuals in such atmospheres may be asphyxiated. Isobutylene, a component of this gas mixture, maycause drowsiness and other central nervous system effects in high concentrations; however, due to its lowconcentration in this gas mixture, this is unlikely to occur.

SYMPTOMS OF OVER-EXPOSURE BY ROUTE OFEXPOSURE: The most significant route of over-exposure for thisproduct is by inhalation.INHALATION: Due to the small size of an individual cylinder ofthis product, no unusual health effects from over-exposure to theproduct are anticipated under routine circumstances of use. Thechief health hazard associated with this gas mixture is when thisproduct contains less than 19.5% Oxygen and is released in asmall, poorly-ventilated area (i.e. an enclosed or confinedspace). Under this circumstance, an oxygen-deficientenvironment may occur. Individuals breathing such anatmosphere may experience symptoms which includeheadaches, ringing in ears, dizziness, drowsiness,unconsciousness, nausea, vomiting, and depression of all thesenses. Under some circumstances of over-exposure, deathmay occur. The effects associated with various levels of oxygenare as follows:CONCENTRATION OF OXYGEN OBSERVED EFFECT12-16% Oxygen: Breathing and pulse rate

increase, muscular coor-dination slightly disturbed.

10-14% Oxygen: Emotional upset, abnormalfatigue, disturbed respiration.

6-10% Oxygen: Nausea, vomiting, collapse, orloss of consciousness.

Below 6%: Convulsive movements, possible respiratory collapse, and death.

HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Over-exposure to this gasmixture may cause the following health effects:ACUTE: Due to the small size of the individual cylinder of this product, no unusual health effects from exposureto the product are anticipated under routine circumstances of use. The most significant hazard associated withthis gas mixture when it contains less than 19.5% oxygen is the potential for exposure to oxygen-deficientatmospheres. Symptoms of oxygen deficiency include respiratory difficulty, ringing in ears, headaches, shortnessof breath, wheezing, headache, dizziness, indigestion, nausea, unconsciousness, and death. The skin of a victimof over-exposure may have a blue color. Additionally, Isobutylene, a component of this gas mixture, may causedrowsiness or central nervous system effects in high concentrations; however, due to its low concentration in thisgas mixture, this is unlikely to occur.CHRONIC: There are currently no known adverse health effects associated with chronic exposure to this gasmixture.TARGET ORGANS: Respiratory system.

4. FIRST-AID MEASURESRESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THISPRODUCT WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing Apparatus must be worn.No unusual health effects are anticipated after exposure to this product, due to the small cylinder size. If anyadverse symptom develops after over-exposure to this product, remove victim(s) to fresh air as quickly aspossible. Only trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitationif necessary.

6. ACCIDENTAL RELEASE MEASURESLEAK RESPONSE: Due to the small size and content of the cylinder, an accidental release of this productpresents significantly less risk of an oxygen deficient environment and other safety hazards than a similarrelease from a larger cylinder. However, as with any chemical release, extreme caution must be used duringemergency response procedures. In the event of a release in which the atmosphere is unknown, and in whichother chemicals are potentially involved, evacuate immediate area. Such releases should be responded to bytrained personnel using pre-planned procedures. Proper protective equipment should be used. In case of a leak,clear the affected area, protect people, and respond with trained personnel.Allow the gas mixture to dissipate. If necessary, monitor the surrounding area (and the original area of therelease) for oxygen. Oxygen levels must be above 19.5% before non-emergency personnel are allowed to re-enter area.If leaking incidentally from the cylinder, contact your supplier.

7. HANDLING and USEWORK PRACTICES AND HYGIENE PRACTICES: Be aware of any signs of dizziness or fatigue, especially ifwork is done in a poorly-ventilated area; exposures to fatal concentrations of this product could occur without anysignificant warning symptoms, due to oxygen deficiency. Do not attempt to repair, adjust, or in any other waymodify cylinders containing this gas mixture. If there is a malfunction or another type of operational problem,contact nearest distributor immediately.STORAGE AND HANDLING PRACTICES: Cylinders should be firmly secured to prevent falling or beingknocked-over.

16. OTHER INFORMATIONINFORMATION ABOUT DOT-39 NRC (Non-Refillable Cylinder) PRODUCTS

DOT 39 cylinders ship as hazardous materials when full. Once the cylinders are relieved of pressure (empty)they are not considered hazardous material or waste. Residual gas in this type of cylinder is not an issuebecause toxic gas mixtures are prohibited. Calibration gas mixtures typically packaged in these cylinders areNonflammable n.o.s., UN 1956. A small percentage of calibration gases packaged in DOT 39 cylinders areflammable or oxidizing gas mixtures.For disposal of used DOT-39 cylinders, it is acceptable to place them in a landfill if local laws permit. Theirdisposal is no different than that employed with other DOT containers such as spray paint cans, householdaerosols, or disposable cylinders of propane (for camping, torch etc.). When feasible, we recommendedrecycling for scrap metal content. Air Liquide America will do this for any customer that wishes to returncylinders to us prepaid. All that is required is a phone call to make arrangements so we may anticipate arrival.Scrapping cylinders involves some preparation before the metal dealer may accept them. We perform thisoperation as a service to valued customers who want to participate.

MIXTURES: When two or more gases or liquefied gases are mixed, their hazardous properties may combine tocreate additional, unexpected hazards. Obtain and evaluate the safety information for each component beforeyou produce the mixture. Consult an Industrial Hygienist or other trained person when you make your safetyevaluation of the end product. Remember, gases and liquids have properties which can cause serious injury ordeath.Further information about the handling of compressed gases can be found in the following pamphlets publishedby: Compressed Gas Association Inc.

1. INTRODUCTION

This Field Sampling Plan (FSP) has been prepared has been prepared as an addendum to the Work Plan for Supplemental Site Investigation for the Gunpowder Point Engineering Evaluation/Cost Analysis (EE/CA). The U.S. Fish and Wildlife Service (FWS) has contracted with Geosyntec Consultants, Inc. (Geosyntec) to complete the EE/CA, which is being performed in accordance with 40 CFR 300.415, and was authorized under GSA contract GS10F0106M, FWS Delivery Order No. F11PD03291. The FWS has the authority to undertake Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) response actions, under 42 United States Code (USC) 9604, 10 USC 2705, and Federal Executive Order 12580.

The study area for this project includes the 30-acre upland feature “Gunpowder Point” (Site) that juts westward into San Diego Bay from the surrounding Sweetwater Marsh area. This FSP document has been prepared both for planning purposes and as guidance to field personnel to direct sampling and analysis of soil, groundwater, and surface water at the Site, as directed in the Work Plan. Analytical requirements as well as methods for completing the field activities are included in this FSP. It is intended that data collected through implementation of this FSP will meet project-specific Data Quality Objectives (DQOs) described in the QAPP.

2. DATA USE OBJECTIVES

The supplemental site investigation is being conducted to: 1) determine sources and nature and extent of contaminants of concern in soil and groundwater; 2) assess the presence of other potential contaminants, including known and potential former industrial facilities and areas affected by former industries that operated at the Site (complete delineation); 3) estimate Site-specific background concentrations for metals and perchlorate; and 4) evaluate groundwater flow regime. Soil samples will be collected for analytical testing to confirm the absence/presence of additional COCs such as dioxins/furans, VOCS, and SVOCs to evaluate potential impacts from former site uses.

OU 2 001800


GPP FSP.doc 2 1/16/2012

3. SOIL, GROUNDWATER, AND SURFACE WATER SAMPLING

3.1 General

The following sections contain standard operating procedures for soil, groundwater, and surface water sampling activities. Field personnel shall follow these procedures, unless field conditions require deviations. In those cases, field personnel shall document the alternate procedures employed and the reasons for the deviations. Soil and groundwater sample locations are discussed in the Work Plan.

3.2 Soil Sampling

Approximately 20 soil borings will be completed using a truck mounted direct-push drilling rig at locations distributed across the Site. Borings will include continuous soil cores to approximately 15 feet below ground surface (bgs), to refusal, or groundwater, whichever is encountered first. Soils will be described, field screened for volatile organic compounds (VOCs), and soil samples collected for analytical testing. Soil types will be characterized using the Universal Soil Classification System (USCS). Soil samples will be screened in the field using visual observations, odors, and a field instrument, such as a photoionization detector (PID), to evaluate the presence of contamination and identify samples which will be submitted for laboratory analysis.

Sample depths will be based on the depths where COCs previously were detected at concentrations greater than the regulatory standards, as detailed in the Work Plan.

Soil samples will be placed in two 8-ounce glass jars with Teflon lined lids provided by the laboratory. Transfer of soils should be done with a nitrile-gloved hand if possible. Gloves should be changed between each sample location. Otherwise a decontaminated stainless steel spoon or scoop may be used. This tool will need to be decontaminated between samples as specified in the QAPP. All sample containers will be labeled, and chilled to 4 ± 2° C in a cooler, and transported to the designated laboratory under chain of custody protocol.

OU 2 001801


GPP FSP.doc 3 1/16/2012

Following completion of the boring, the hole will be backfilled with hydrated bentonite and the surface patched to match the surrounding surface. The location of the boring will be recorded on the boring log using a handheld GPS.

3.3 Monitoring Well Installation

Two groundwater monitoring wells will be installed to assist in evaluation of groundwater quality and flow direction. The monitoring wells will be installed using a direct push drilling rig, and will be constructed using a pre-packed, 10-foot long, 1-inch diameter PVC well screen. The target depths for the monitoring well screens are approximately 7 to 17 feet below ground surface. Additional filter pack sand will be placed around the screen up to approximately 1 foot above the screen, then backfilled with hydrated bentonite to seal the filter pack up to the ground surface.

The new wells will be developed through pumping and surging, and then allowed to equilibrate at least 24 hours after development prior to sampling. Following installation, the new and existing wells will be surveyed by a licensed surveyor.

3.4 Groundwater Sampling

Groundwater monitoring will be conducted at the four existing and two new monitoring wells, including measuring depths to water and collection of groundwater samples for analytical testing using low-flow purging and sampling techniques. Prior to sampling, groundwater will be purged from the well casing until field parameters (oxidation-reduction potential [ORP], dissolved oxygen [DO], pH, temperature, and conductivity) stabilize. Field parameters will be measured using a flow-through cell and water parameter analyzer (e.g. YSI or Horiba). Once field parameters are stable, the flow through cell will be disconnected and groundwater samples will be collected directly into laboratory-supplied containers. Purging and sampling will be conducted using a peristaltic pump, and dedicated or disposable tubing, and documented on a groundwater sampling field log. Samples will be labeled, logged on a chain of custody, placed into a cooler with ice, and transported to the designated laboratory under chain of custody procedures.

OU 2 001802


GPP FSP.doc 4 1/16/2012

3.5 Surface Water Sampling

Surface water samples will be collected from four locations near (downgradient from) monitoring wells. Sample points will be marked with a stake at each designated location. Surface water will be collected from an area with flowing water, not stagnant or ponded water, if possible. Care needs to be taken to collect upstream from where the sampler enters the water to minimize sediment disturbance.

Surface water is collected in an unpreserved container or dedicated transfer bottle and then transferred into the laboratory-supplied sample containers. Care should be taken to ensure the samples are collected from mid-column depth in the water to avoid disturbance from the surface or sediment. Submerge the bottle with the lid secured while lowering the container. Upon reaching the desired sampling depth, unscrew the lid and allow the bottle to fill completely. When the container is full, secure the lid prior to removing it from the water. If dissolved metals are being analyzed, the water will be filtered from the transfer container into the sample container using a peristaltic pump, dedicated tubing and a disposable 0.45 micron filter. Samples bottles will be labeled, logged on the chain of custody, placed into a cooler with ice, and transported to the designated laboratory under chain of custody protocol.

3.6 Analytical Methods

The laboratory analytical methods for evaluating the soil samples collected have been chosen based on results of previous investigations and review of past site activities. Analytical methods for each media are listed below.

Soil:

• Perchlorate by EPA Method 6860;

GPP FSP.doc 6 1/16/2012

4. TRANSDUCER STUDY

Following soil and groundwater sampling and testing, pressure transducers will be placed in four of the groundwater monitoring wells for approximately two weeks. Solinst™ Gold “level-loggers or similar pressure transducers will be suspended within the well casing on a stainless steel cable. In one of the four wells well, a baro-logger will be suspended above the water level to record barometric pressure fluctuations during the study period. Groundwater elevations will be corrected for variations in atmospheric barometric pressure using proprietary software supplied by Solinst.

Data obtained from the transducers will be plotted graphically and correlated with groundwater levels measured during sampling of each of the wells and calculated groundwater flow directions. Groundwater elevation data obtained from the transducers also will be correlated graphically to publically available NOAA tide information (#9410170 for San Diego, CA). These correlations will be used to analyze the relationship between on-site groundwater and the surrounding marsh and bay.

5. INVESTIGATION-DERIVED WASTE MANAGEMENT

Investigation-derived waste (IDW) anticipated to be generated during the project includes soil cuttings, decontamination, and purge water. Soil cuttings will be placed in a Department of Transportation (DOT)-approved 55-gallon drum, labeled, and placed in an approved location on the Site. Decontamination and purge water will also be placed in a DOT-approved 55-gallon drum, labeled, and moved to an approved location on the Site. The drums will be transported off-site for disposal following receipt of analytical testing by a sub-contractor vendor. Disposable items, such as sample bags, gloves, protective overalls, and paper towels will be placed in plastic bags after use and deposited in solid waste receptacles for disposal.

OU 2 001805


GPP FSP.doc 7 1/16/2012

6. POST-SAMPLING ACTIVITIES

6.1 Sample Handling

Samples will be placed in laboratory-supplied containers, sealed, labeled, and shipped in accordance with standard sample handling and chain of custody procedures specified in Section 4 of the QAPP.

6.2 Equipment Decontamination

Decontamination of sampling equipment shall be performed to reduce the potential for cross-contamination between sampling points. Sampling equipment will be decontaminated in accordance with the QAPP.

6.3 Field Documentation

A combination of a field notebook, groundwater sample sheets, chain of custody, and field boring logs will be used to document field activities such as drilling and sample collection. Field notebook (stapled booklet with numbered pages) entries will include as much detail as possible so that persons going to the Site could reconstruct a particular situation without reliance on memory of the author. Field notebooks will be stored in the project file when not in use. The field notebooks will contain a variety of information including the date, starting and finishing time of activities, project number, documentation of safety meeting, weather, unexpected work stoppages due to change in site conditions or safety moment, documentation of generated waste that will not leave the site and names of all sampling and/or investigative personnel present. All notebook entries shall be made in indelible ink, and each page initialed and dated by the sampler. The groundwater sample sheets shall include a full description of the sample, its origin, sampling time, date, and personnel. The sample will be assigned an identification code according to site-specific sample-naming protocols as identified below.

Field boring logs will be completed for each boring and include information on the location, geologist, driller, equipment, and size of drill tooling. The log should also include the soil USCS descriptions, symbols, PID readings, core runs and recoveries, soil sample identification, sample time and number of sample containers collected.

OU 2 001806


GPP FSP.doc 8 1/16/2012

Other notes regarding difficulties or drilling characteristics should also be included on the field boring log. If available, GPS coordinates for the boring should be included on the log and/or in the field notebook.

A groundwater sample sheet will be completed for each monitoring well sample. This includes condition of the well, depth to water measurements, and recording of groundwater field parameters during low-flow purging. The sample identification, time, and containers collected are also recorded along with analytical testing requested.

A chain of custody (COC) document supplied by the laboratory is filled out whenever samples are collected. The sample identification, date and time of collection, number of containers and analytical testing requested are all recorded on the COC. Sampler’s signature and time and date of sample relinquishment to laboratory personnel are also recorded. If possible, it is recommended that each media is recorded on different COC, keeping all soils on a different COC to the surface water and groundwater. A copy of the COC is obtained from the laboratory when turning over the samples and the copy is put into the project file.

6.4 Sample Naming Protocol

Sample identification or naming protocol for groundwater, surface water and soil samples will be based on the boring location name, media being sampled and then depth at which the depth is being sampled. For instance, a groundwater sample collected from boring B-12 at 14 feet bgs would be: GP-B12-GW-14. For monitoring wells, the date will be inserted instead of the depth at the end of the sample name: MW-1: GP-MW1-DATE. A soil sample from the same boring but at a depth of 5 to 6 feet would be identified as GP-B12-SO-5-6. A surface water sample would not have a depth associated with it so it would be indicated by the location identification and a “SW”, or GP-SW1-1-DATE. Since the label will contain the date and time of sampling, this need not be included in the sample identification.

(Geosyntec) to complete the EE/CA, which is being performed in accordance with 40 CFR 300.415, and was authorized under GSA contract GS10F0106M, FWS Delivery Order No. F11PD03291. The FWS has the authority to undertake Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) response actions, under 42 United States Code (USC) 9604, 10 USC 2705, and Federal Executive Order 12580.

The study area for this project includes the 30-acre upland feature “Gunpowder Point” (Site) that juts westward into San Diego Bay from the surrounding Sweetwater Marsh area. The purpose of this QAPP is to outline specific quality assurance/quality control (QA/QC) procedures such that data collected for the project meet the Data Quality Objectives (DQOs) and is of acceptable quality to meet FWS requirements. This QAPP has been prepared in general accordance with USEPA Requirements for Quality Assurance Project Plans (USEPA 2001), and Guidance for Quality Assurance Project Plans (USEPA 2002). This QAPP provides 1) a description of the data quality objectives associated with soil, surface water, and groundwater sampling; 2) describes the procedures for sampling and analysis quality control; and 3) presents requirements for corrective actions and system and performance audits.

2. DATA USE OBJECTIVES

The supplemental site investigation is being conducted to: 1) determine sources and nature and extent of contaminants of concern in soil and groundwater; 2) assess the presence of other potential contaminants, including known and potential former industrial facilities and areas affected by former industries that operated at the Site (complete delineation); 3) estimate Site-specific background concentrations for metals and perchlorate; and 4) evaluate groundwater flow regime. Soil samples will be collected for analytical testing to confirm the absence/presence of additional COCs such

OU 2 001815



as dioxins/furans, VOCS, and SVOCs to evaluate potential impacts from former site uses.

3. DATA QUALITY OBJECTIVES

3.1 General

Data quality is measured by the ability of the collected data to meet specific quantitative and qualitative objectives. Quantitative objectives include precision, accuracy, and completeness. Qualitative objectives include representativeness and comparability. The QA/QC procedures for this project require that the data meet minimum requirements for precision, accuracy, completeness, representativeness and comparability.

3.2 Precision

Precision is the degree of agreement between independent measurements. Analytical precision measures the variability associated with repetitive analyses of the same sample. Laboratory quality control samples are used to assess precision.

For this project, laboratory quality control duplicate samples will be collected. The laboratory’s Quality Control Program requirements will set forth the allowable difference in results for duplicate samples. If the precision is not met, the data will be flagged for reporting purposes.

3.3 Accuracy

Accuracy is a measurement of the correctness of the analyses. Field and laboratory activities are subject to accuracy checks.

Laboratory accuracy can be assessed using laboratory spike samples. A spiked sample is a non-project-specific sample of known concentration that is analyzed by laboratory personnel using the same procedures and methods used for the project-specific samples. A measurement is accurate when the concentration measured during the analysis matches the known concentration of the spiked sample (i.e., the percent recovery is

OU 2 001816



sufficiently high). A California-certified analytical laboratory (Calscience) will be used to conduct all the analyses and will meet accuracy objectives established in accordance with their certification.

Field accuracy will be assessed using field and equipment blanks. Analysis of the blanks will reveal, if present, errors such as the following: field contamination; sample preservation problems; sample handling errors; or deficiencies in sampling technique. The field activities will be considered accurate if the field, trip and equipment blanks have results less than the project reporting limits for each analyte.

3.4 Completeness

Completeness describes the content of the data set once errors, if any, have been identified and flagged and the data failing to meet the DQOs have been removed from the data set. The data set will be considered complete if at least 95 percent of the data collected is usable without meaningful flags or errors.

3.5 Representativeness

Representativeness describes the degree to which the data collected are an accurate characterization of the media sampled. Careful planning of the field activities based on known conditions and historical site usage has been undertaken to promote a representative plan.

3.6 Comparability

Comparability is a measure of the confidence with which one data set can be compared to another. The data set will be considered comparable when USEPA or other standard methods have been used for analyses, the data set is representative and the field activities meet the standards and requirements set forth by the FWS, if any.

OU 2 001817



4. QUALITY CONTROL PROCEDURES

4.1 General

The Field Sampling Plan (FSP) outlines the sampling and analysis procedures that will be implemented during the field activities (Appendix c of the Work Plan). The QA/QC procedures that apply to these field sampling activities are presented in this section of the QAPP. These activities have been designed in order to comply with the data use objectives presented in Section 2.

4.2 Equipment Decontamination

Non-dedicated sampling equipment will be decontaminated before and after samples are collected. Decontamination will consist of (in the following order): potable water rinse, detergent (e.g., Alconox) solution, and potable water rinse. During soil sampling, if a stainless steel spoon or scoop is used to transfer soil from the direct push sleeve to the sample container, this tool will need to have a nitric acid rinse following the wash with Alconox. Decontamination of personal protective equipment (PPE) is addressed in the Health and Safety Plan (HASP), although disposable gloves will be used during sampling and decontamination procedures.

4.3 Materials and Supplies

Supplies and materials used either in the field or the laboratory shall be standard industry material. The supplies and materials shall be inspected prior to use, be in good working condition and within the expiration date requirements specified by the manufacturer.

4.4 Sample Handling and Shipping

Soil samples will be placed into a cooler with ice immediately after sampling. If wet ice is used, ice will be double-bagged in large plastic zip-top bags and properly sealed. Breakable or otherwise fragile sample containers will be wrapped in plastic bubble-wrap to prevent damage during shipment. All bottles will be placed in separate and appropriately sized plastic zip-top bags and sealed.

OU 2 001818



Two to four inches of packing material or several layers of bubble wrap will be placed on the bottom of the cooler, and over the top of the sample containers once placed into the cooler. Ice will be placed below and above sample containers and in sufficient quantity for shipping times. Completed Chain-of-Custody Records for the laboratory (described below) will be sealed in a plastic zip-top bag and taped to the inner side of the cooler’s lid. Packing tape will then be wrapped around the cooler two times and clear tape will be placed over custody seals.

4.5 Chain-of-Custody Requirements

Chain-of-custody records will be maintained for each sample collected to provide an accurate written record of the possession and holding of samples from the time of collection through data analysis and reporting. The following information will be specified for each sample on the chain-of-custody form:

• Sample identification;

• Sample date;

• Sample time;

• Sample location and depth, if appropriate;

• Preservative, if appropriate;

• Analyses to be performed; and

• Special instructions to the laboratory.

The sampler and any other intermediate handlers of the samples (i.e., laboratory courier) shall sign the form and record the date and time at which the samples changed possession. The completed chain-of-custody form will be sealed inside of the cooler or other sampling container. Upon receipt of samples by the laboratory, the laboratory will be responsible for maintaining internal chain of custody of the samples.

5. QUALITY ASSURANCE/QUALITY CONTROL REQUIREMENTS

5.1 General

Quality control of laboratory analysis will be ensured by (i) performing analytical methods according to prescribed protocols and (ii) analyzing laboratory QA/QC samples to measure precision and accuracy of laboratory methods and equipment, instrument calibration and preventive maintenance. These procedures are described below.

5.2 Analytical Methods

Laboratory analyses for each chemical parameter will be performed in accordance with prescribed USEPA protocols. Laboratory analyses for physical parameters will be performed in accordance with the prescribed protocols established by the methods listed in Table 1 of the FSP.

Analyses will be performed in accordance with these procedures unless project requirements necessitate the adoption of alternative methods. If an alternative method is used, it will be documented and reported.

5.3 Laboratory Quality Assurance/Quality Control

5.3.1 General

Laboratory QA/QC samples that will be analyzed during the proposed investigation include method blanks, laboratory control samples, matrix spikes, duplicates and surrogates.

5.3.2 Method Blanks

A method blank is a sample of deionized, distilled water prepared by and analyzed by the laboratory. It is used to assess potential contamination in the laboratory process (e.g., contaminated reagents, improperly cleaned, or calibrated equipment).

OU 2 001820



5.3.3 Laboratory Control Samples

A laboratory control sample is a known matrix (e.g., washed sand, lab reagent water) that has been spiked with a known concentration of specific target analytes. It is used to demonstrate the precision of the analytical process.

5.3.4 Matrix Spikes

The matrix spike is an actual sample matrix spiked with known concentrations of specific target analytes. The purpose of a matrix spike is to access the effect of a sample matrix on the recovery of target analytes (i.e., assess the accuracy of the analytical measurements on the particular matrix). One matrix spike will be analyzed per 20 soil samples.

5.3.5 Laboratory Duplicates

Duplicate samples are used to assess precision in the analytical method. An additional aliquot is extracted from the primary sample and analyzed using the identical procedures as the primary sample. Then the results are compared to assess the precision. Duplicates will be of two kinds: laboratory control sample duplicates and matrix spike duplicates. Duplicates will be analyzed each time a laboratory control sample or matrix spike sample is analyzed.

5.3.6 Surrogates

A surrogate is an analyte isomer compound spiked into each sample analyzed. Surrogates assess the precision and accuracy of each individual analysis based on the surrogate recoveries. A surrogate (typically more than one) will be analyzed for each primary sample.

5.4 Field Quality Assurance/Quality Control

5.4.1 General

OU 2 001821



Field QA/QC samples that will be collected during the proposed investigation include duplicates, field blanks, and equipment blanks. The description and purpose of these samples is discussed in this section.

5.4.2 Field Duplicates

Field duplicates will be collected to evaluate sample collection precision. Field duplicates will be obtained at a rate of one field duplicate per 20 samples for each media source sampled. Field duplicates will be submitted for the same analytical testing as the primary samples. Field duplicates will be logged on the chain of custody as “blind” samples, and logged in the field book/notes with their primary sample.

5.4.3 Trip Blanks

Trip blank samples will be included in all sample batches that include samples to be analyzed for VOCs. It will consist of a laboratory supplied 40-milliliter container filled with reagent-grade deionized water and preservative, as indicated in Table 1 of the FSP. During soil sampling, one field blank sample per day will be included in a container used to transport the soil samples. Field blanks will be submitted for VOC analysis by

EPA Method 8260, if VOCs are part of the analytical suite.

5.4.4 Equipment Blanks

Equipment blank samples are obtained by filling decontaminated sampling equipment with distilled water or pouring the distilled water over the sampling equipment, sampling this water, and submitting the sample for analysis. During soil sample collection, soil cores are collected using a dedicated acetate sleeve inside the direct push tooling and thus there will be no need for an equipment blank. During groundwater sampling, one equipment blank sample will be collected from the decontaminated pump used to purge and sample each of the six monitoring wells or the depth to water meter. The equipment blank will be analyzed to assess potential contamination from the sampling equipment.

6. EQUIPMENT MAINTENANCE AND CALIBRATION

6.1 General

Both field and laboratory equipment involved with the collection and analysis of the samples will be maintained and calibrated to the requirements specified below.

6.2 Laboratory Equipment

6.2.1 Laboratory Preventative Maintenance

The analytical laboratory will maintain an adequate supply of critical equipment and analysis items to prevent loss of data due to equipment malfunction. These include, but are not limited to, calibration standards, reagents, glassware, and analytical equipment.

6.2.2 Laboratory Instrument Calibration

Instruments will be calibrated with standard solutions appropriate for the analytical method to be performed. Laboratory personnel will calibrate equipment according to and at the frequency prescribed by the manufacturer's directions and the requirements of the prescribed analytical methods. Initial and continuing instrument calibrations will meet applicable California certification requirements.

6.3 Field Equipment

6.3.1 Field Equipment Preventative Maintenance

Sample collection equipment will be examined, tested, and decontaminated prior to use. Sampling personnel will maintain a supply of key equipment items in the field to prevent extended sampling delays associated with equipment malfunction. These include, but are not limited to, tubing, fittings, sample containers, calibration standards, tools, and cleaning equipment.

OU 2 001823



6.3.2 Field Instrument Calibration

Field instruments will be calibrated with standard solutions or gases appropriate for the analytical method to be performed. Instrument manufacturer recommendations and established analytical procedures will be utilized in formulating the guidelines for calibration frequency and the concentration of the calibration standards. Calibration data will be recorded in the daily field reports.

7. DATA MANAGEMENT

7.1 General

This section deals with the generation of both laboratory and field data and the protocol for the recording, managing, validating, and reporting this information.

7.2 Laboratory Data

Laboratory analytical data will be reported on data sheets that include laboratory and field sample designations, sample date, sample time, date of extraction (if any), date of analysis, and method of analysis. Laboratory supervisory personnel shall review each data sheet and sign and date the data package in accordance with the laboratory’s internal quality control program.

7.3 Field Data

Daily field reports or field logbooks will be completed to document data collection activities, including a description of the sample, its origin, sampling time, date, and personnel. Entries will include sufficient detail to potentially reproduce sampling activities. Field log entries shall be made in indelible ink, with each page initialed and dated by the sampler. Errors made on data forms will be lined out and initialed.

OU 2 001824



7.4 Data Validation

7.4.1 General

Data will be evaluated for accuracy, precision, completeness, representativeness, and comparability through the data validation process. The validation will comprise review of holding times, detection limits, analyses of laboratory quality control information, and data completeness as discussed below.

7.4.2 Chain of Custody

The laboratory will return an electronic copy of the chain-of-custody forms with the laboratory data sheets. The forms will be inspected by Geosyntec to verify that a proper chain of custody has been recorded for each sample and that the laboratory received the samples properly preserved and in good condition.

7.4.3 Holding Times

Each analytical method has an associated prescribed holding time, which is the maximum amount of time after collection that a sample may be held prior to extraction and/or analysis. Accuracy and sample integrity are questionable for samples extracted and/or analyzed beyond holding times due to potential physical and/or chemical changes to the sample. Analytical reports will be reviewed to verify that analytical method-specific holding times were met. If the holding times have been exceeded, the data will be flagged, may be excluded, and re-sampling may be contemplated.

7.4.4 Detection Limits

Laboratory data will be checked to verify that the detection limits are at or below the project reporting limits. In some cases, it may be necessary to elevate detection limits for target analytes if an inadequate volume of sample is collected or if dilution is necessary either to counter matrix interference or to bring target analyte concentrations to within the calibration linear range. Such deviations from the project reporting limits will be noted and the meaningfulness of the data will be evaluated. Results reported as below elevated detection limits will be noted and interpreted with care.

OU 2 001825



7.4.5 Blanks

Blank samples will be analyzed to check for potential sample contamination as a measure of accuracy. Analytical reports will be reviewed to identify whether contamination occurred in the blank. Blank samples will include method, equipment, and field blanks. If concentrations greater than the project reporting limits are detected, the data will be flagged. The cause of the contamination will be investigated, the entire data set will be reevaluated, and recommendations for re-analysis, if necessary, will be made.

7.4.6 Duplicates

Duplicate samples will be validated and the precision and accuracy of the laboratory methods assessed. Duplicate samples that vary from one another by more than 30% for soil samples will be flagged and either excluded from the data set or reported and explained with qualifiers. Duplicates will include field duplicates, laboratory control sample duplicates, and laboratory spike duplicates. As indicated above, during soil sampling, one duplicate per 20 samples will be collected.

7.4.7 Spikes, Surrogates and Control Samples

Laboratory spike samples, surrogates and control samples will be evaluated to assess laboratory accuracy. The percent recovery is specified per analyte based on the laboratory’s Quality Assurance/Quality Control program. The percent recovery will be evaluated versus the laboratory’s quality control limits. Samples outside the limits will be flagged and either excluded from the data set or reported and explained with qualifiers.

7.4.8 Data Completeness

The data set will be considered complete if at least 95 percent of the data collected is usable once errors, if any, have been identified and flagged and the data failing to meet the DQOs have been removed from the data set. If the goal is not achieved, the rationale for the incompleteness will be assessed and reported.

OU 2 001826



7.5 Reports to Management

The QA/QC results will be documented and identified issues (i.e., laboratory and field) will be reported to the Geosyntec Environmental Manager. The Geosyntec Environmental Manager will evaluate the impact of the QA/QC issues and implement solutions.

8. CORRECTIVE ACTION

Results that do not meet data quality objectives will be reviewed. Raw analytical data, laboratory notebooks, or other laboratory data may be obtained and examined as necessary. Identified problems will be corrected prior to reanalysis. If necessary, a re-sampling in the field may be performed. Corrective actions will be reviewed for certainty that resolution was achieved.
