EXECUTIVE SUMMARY

This document is a revision to the "Plan for Soil/Water Leaching Tests of Contaminated

Soils." The original plan detailed a laboratory investigation to evaluate soils from the Dover

Chemical site containing chlorobenzenes, chloroform, and carbon tetrachloride to determine

the leaching or soil/water partitioning behavior of these compounds in the unsaturated and

saturated zones. This revision outlines an extension of the laboratory investigation to

evaluate soils and sediments containing polychlorinated dibenzo-p-dioxins (PCDD) and

dibenzofurans (PCDF), hexachlorobenzene (HCB), and alpha-hexachlorocyclohexane (alpha-

BHC), as well as a modification of the investigation for the orginal parameters.

The objective of this investigation is to determine the distribution of these constituents

between the aqueous and solid phases using soil and groundwater collected from the site.

This information will be used to assess the potential impact of soils on groundwater quality

over an extended period of time and to help estimate the rate of groundwater remediation.

In addition, the information will be used to support the selection and implementation of a

remedial action alternative for soils at the Dover Chemical Plant.

Three soil samples will be collected from various areas of the plant. A site composite of

near-surface soil will be collected for leach testing of PCDD/PCDF, HCB, alpha-BHC, and

antimony. An additional sample will be collected near Building 21 for leach testing of

alpha-BHC at higher concentrations. One sample from the gravelly sands in Area H will

be collected in or near the saturated zone for leach testing of PCDD/PCDF, HCB and

alpha-BHC. In addition, a sediment sample from the inlet of the abandoned canal will be

leach tested for PCDD/PCDF, HCB, and alpha-BHC. Samples will also be analyzed for

volatile and semivolatile organic compounds, organic carbon (OC), and physical parameters.

The soil/water partitioning studies will utilize a modification of an extraction vessel and an

agitation device described in EPA's Method 1311 Toxicity Characteristic Leaching Procedure

(TCLP). In most of the tests, upgradient groundwater will be used to extract constituents

1091.wr ES-1

from the soil and sediment samples. The material in the bottle extraction vessel will be

separated into its aqueous and solid phases and both phases will be analyzed for the target

analytes. In addition, the solid phase will be analyzed for moisture.

An additional extraction will be used to evaluate the effect of chlorobenzenes in the

groundwater on the soil/water partition coefficients for the gravelly sand sample from Area

H. Groundwater collected from a well that contained the highest level of chlorinated

benzenes on-site (e.g., MW-11A or MW-11B) will be mixed with the soil sample to

determine the partition coefficient in the presence of a significant cosolvent concentration.

Where applicable, all field and laboratory QA/QC protocols in the "Sampling and Analysis

Plan to Complete the Remedial Investigation at the Dover Chemical Facility, Dover, Ohio"

(SAP) and the "Quality Assurance Project Plan for Additional Investigation Work, Dover

Chemical Facility, Dover, Ohio" (QAAP) will be followed for these soil/water partitioning

studies. In addition, the Safety Plan in the SAP and its addendum will be followed during

sampling activities, and the schedule for these studies will coincide with the overall RI/FS

work completion.

Each of the four soils from the various site areas sampled will also undergo a TCLP test

consistent with the approach discussed in the original plan. TCLP extract will be analyzed

for hazardous constituents that may render the soil hazardous and impact disposal options

if off-site disposal is required. Only hazardous constituents for which regulatory levels for

waste extract have been promulgated will be tested using the TCLP.

1091-wr ES-2

SECTION 1

BACKGROUND

Dover Chemical Corp. and Roy F. Weston, Inc. (WESTON) submitted the "Plan for

Soil/Water Leaching Tests of Contaminated Soils (Third Draft) in May 1989 to the U.S.

EPA and the Ohio EPA. The plan was approved in June 1989. Under the plan, soils

containing target chlorinated organic compounds would be evaluated in the laboratory to

determine the leaching or soil/water partitioning behavior of these compounds in the

unsaturated and saturated zones. This information was to be used to assess the impact of

soils on groundwater quality over an extended period of time and to help predict the rate

of groundwater remediation. In addition, the information was to be used to support the

selection and implementation of a successful remedial action alternative for contaminated

soils at the Dover Chemical Plant in Dover, Ohio. This included testing soil samples

according to Toxicity Characteristic Leaching Procedure (TCLP), as requested by OEPA,

to assess the applicability of landfilling/land ban requirements.

To date, soil and groundwater samples from the saturated zone have been collected from

MW-11C at the Dover Chemical Plant and analyzed for VOCs and selected SOCs. The

results of these analyses have been used to calculate preliminary soil/water partition

coefficients in a letter dated 20 July 1989. However, the unsaturated zone tests have not

been conducted.

Since the approval of the "Plan for Soil/Water Leaching Tests of Contaminated Soils,"

sampling and analysis for additional analytes were completed. These results, and the results

of follow-up testing, indicated that PCDD/PCDF, HCB, and alpha-BHC are present in site

soils. In order to meet the objectives of determining the impacts of soil concentrations on

groundwater quality, the partitioning behavior of PCDD/PCDF, HCB and alpha-BHC

should also be determined. While the original plan has provisions for analysis of additional

parameters, factors such as the sample size required make it necessary to conduct separate

tests for PCDD/PCDF, HCB, alpha-BHC, and antimony. Therefore, modifications to the

1091.W 1-1

original plan are required to include tests for these constituents. The necessary

modifications are described in this revision to the plan. Leaching tests of these soils will

also be conducted for the VOCs and selected SOCs identified in the original plan, and

TCLP tests will be conducted as well.

1091-wr

SECTION 2

OVERVIEW

As with the test procedures for volatiles (described in the original plan) the methodology

selected for the PCDD/PCDF, HCB, alpha-BHC, and antimony soil/water partitioning

studies is based on EPA's Method 1311 Toxicity Characteristic Leaching Procedure (TCLP).

However, the zero headspace apparatus used for volatiles will not provide the larger extract

volume needed for PCDD/PCDF analysis. Thus, the procedure for when volatiles are not

present (40 CFR Part 261, Appendix II, 7.2) will be used. To obtain soil/water partition

coefficients, the soil/sediment is first mixed with groundwater collected upgradient of the

site. The aqueous and solid phases are then separated and analyzed for each constituent.

A portion of the solid phase is also analyzed for moisture. The soil/water partition

coefficient (Kd) is calculated by dividing the concentration of the constituents in the solid

phase (corrected for moisture) by the concentration in the aqueous phase. The normalized

K^. value is calculated by dividing the Kd by the fraction of organic carbon in the

soil/sediment.

The effect of chlorobenzenes in the soil on the soil/water partition coefficients will also be

evaluated. In these studies, the gravelly sands from Area H (near soil boring SS-2) will be

mixed with groundwater collected from MW-11A, which contained the highest level of

chlorinated benzenes on-site during the Feasibility Study in 1986 (24.7 ppm). If groundwater

sample from MW-11A without pure phase material cannot be obtained, then a groundwater

sample from MW-11B, which contained 17.8 ppm of chlorinated benzenes, will be collected

for the study. The use of groundwater containing chlorinated benzenes is suggested because

the proposed soil samples may not contain enough chlorobenzenes themselves to affect

constituent partitioning. This information can be used to help estimate the potential

migration of PCDD/PCDF, HCB, and alpha-BHC through groundwater in the presence of

chlorobenzene concentrations.

1091.W 2-1

Since the organics will redistribute between the soil/sediment and water during the test, all

soil and sediment samples used in the soil/water partitioning studies will be analyzed for

VOCs and selected SOCs after mixing. Concentrations of chlorinated benzenes in the

mixing water also will be analyzed after all tests for correlation with the partition coefficient.

Soil/sediment from each of the four areas sampled will also undergo the TCLP test as

discussed in the original plan. TCLP extract will be analyzed for constituents that may

render the soil hazardous or impact disposal actions if off-site disposal is required. The

applicable waste types and analytes are discussed in Section 6. Site contaminants for which

regulatory levels have been established for a waste extract and which will be tested by the

TCLP are:

Chlorobenzene

Chloroform

Carbon tetrachloride

1,4-Dichlorobenzene

Hexachlorobenzene

Tetra-, penta, and hexachlorodibenzo-p-dioxins and furans will also be analyzed for potential

leaching.

Although EPA regulations as applied to the soil at the Dover site may not require analysis

of all of these constituents, the information could facilitate decision-making by potential

remediation vendors. Many of the other constituents (e.g., tri-, tetra-, and

pentachlorobenzene, benzene, and other dichlorobenzene isomers) are regulated based on

concentrations in the waste rather than the waste extract. See 40 CFR 261.24, 40 CFR

268.41, and 40 CFR 268.43 for additional information.

1091-wr 2-2

SECTION 3

SAMPLE COLLECTION

The soil sampling program in this investigation is one of the key factors to ensure that data

generated by the soil/water partitioning studies are representative of the leaching of

PCDD/PCDF, HCB, alpha-BHC, and antimony that could occur at Dover Chemical. Three

types of soil/sediments will be collected for testing:

Near-surface unsaturated zone soils (two samples)

Gravelly sand characteristic of the lower unsaturated zone and the saturated zone

Canal sediments

The location and description of each sample is given in Table 3-1 and the area for each

sample is shown on Figure 3-1. Detailed sampling and compositing procedures for all

samples are provided in the Quality Assurance Project Plan (QAAP, 1989).

3.1 UNSATURATED ZONE SOILS - NEAR SURFACE

Two types of near surface soils will be collected, as follows:

• A site-wide composite sample to test the partitioning of PCDD/PCDFs, HCB, alpha-

BHC, and antimony.

• A sample from Area G near the location of the highest alpha-BHC (soil sample G-6)

to test the partitioning of alpha-BHC.

The sitewide composite will consist of aliquots collected from eight locations across the site

as shown in Figure 3-1.

Alpha-BHC was detected in the previous site-wide composite at a much lower concentration

than in Area G and might not contain enough alpha-BHC for the partitioning tests. The

sample from Area G will be collected from a depth of 2 to 4 feet in an attempt to avoid

sampling pure alpha-BHC which is not adsorbed to soil.

Additional amounts of samples will be collected for analysis of organic carbon, physical

parameters, and TCLP testing, as described in Section 6. Two samples each are required

from Area G for the TCLP testing, since the VOC TCLP must be run using the zero

headspace procedure. A VOC TCLP test will not be conducted on the site-wide composite

because VOCs are likely to be lost during compositing, and VOC concentrations are

expected to be low to begin with. The parameters to be analyzed from the TCLP tests are

listed in Section 2. Except for the VOC samples collected for TCLP, no sampling

procedures specific for VOCs and SOCs will be necessary, since the purpose of the analysis

is to characterize the samples as they are in the experimental procedure, not in the field.

VOC and SOC levels will be determined after soil samples are subjected to leaching tests.

Concentrations of VOCs and selected SOCs are expected to be low in these samples such

that they will not influence the partitioning of the PCDD/PCDFs, HCB, or alpha-BHC.

3.2 SATURATED ZONE SOILS - GRAVELLY SAND

Area H is the only area of the site where PCDD/PCDFs have been found at significant

concentrations at depth (due to the presence of cosolvents). To characterize sorption of the

saturated zone soils and the effects of cosolvency on transport, a sample from the first-

encountered gravelly sand in a borehole in Area H will be collected (deeper gravelly sand

may not contain sufficient PCDD/PCDF concentrations to conduct a partition experiment.)

While this soil would preferably be above the water table at the time of sampling, its

characteristics are expected to be representative of the aquifer soils. The boring will be

located near soil boring SS-2, which contained the highest PCDD/PCDF concentrations at

this depth. The sample will be analyzed for the same additional parameters as the near-

surface soils. VOCs and selected SOCs were previously detected in subsurface samples from

1091.wr 3-4

Area H, and their concentrations will be measured at the end of the partitioning test.

Two additional samples will be collected for TCLP and zero headspace TCLP tests for the

parameters listed in Section 2. Sufficient sample volume will also be collected to conduct

an additional partitioning experiment to determine the effect of cosolvents such as

chlorobenzenes on the partitioning of PCDD/PCDFs, HCB, and alpha-BHC. The mixing

water for the additional partitioning test will be groundwater from the monitor well

containing the highest concentrations of chlorinated benzenes (MW-11A) (see Section 5).

Alpha-BHC concentrations in the gravelly sand may not be sufficient to calculate

partitioning coefficients, so the effect of cosolvency on alpha-BHC may not be measurable.

3J CANAL SEDIMENTS

One canal sediment sample will be collected from a depth of 0 to 6 inches near the canal

inlet (prior sample CSD-1). Based on the previous sampling an equivalent TCDD

concentration of 200 ppb is expected. HCB and alpha-BHC were detected in 1989 in canal

sediment at 190 ppm and 5.2 ppm, respectively. Since these compounds are expected to still

be present, their partitioning will also be investigated in these samples. Two additional

samples will be collected for TCLP and zero headspace TCLP tests for the parameters

identified in Section 2.

3.4 SOIL SAMPLING PROTOCOLS

Soil and sediment samples will be collected with a hand or rig-driven split-spoon sampler

(depending upon depth). After encountering the depth interval of interest, the soil sample

will be recovered from the split spoon. Samples to be composited will be mixed in stainless

steel bowls to produce a homogeneous sample. (VOC samples for zero headspace TCLP

tests will not be composited). Extra sample for matrix spike and matrix spike duplicate

analysis will be collected from the near surface soil composite for PCDD/PCDFs, HCB and

alpha-BHC after mixing.

I09i.wr 3-5

After each sample is collected, it will be properly contained, sealed, and shipped to ensure

safe transport. All sample containers will be labeled with the appropriate site designation,

sample number and location. In addition, soil sampling field personnel will follow U.S.

EPA/WESTON's standard chain-of-custody procedure. This procedure will be initiated at

the time of field sampling and followed through the sequence of shipment, laboratory

receipt, and chemical analysis. The sample containers, sample volumes, and preservation

and holding times for each analysis are given in Table 3-1 of the SAP.

Onsite sampling equipment will be decontaminated by steam cleaning and a hexane rinse

before use onsite and between each sampling location at an area set up onsite for this

purpose. The equipment will be inspected to ensure that all soil residues have been

removed. The decontamination will be performed to the satisfaction of the soil geologist

and will be documented in the field notebook. The procedure for decontaminating sampling

equipment is described in Section 4.12 of the QAPP.

The Site Health and Safety Plan in Appendix A of the SAP, and its addendum which is

included in Appendix A of this plan, will be followed during sampling activities. Both of

them will be read and understood by each of the sampling personnel prior to any activity.

Sampling personnel will sign both documents to verify their understanding of the Safety

Plan. This plan will be revised as necessary to ensure that relevant safety procedures are

incorporated. The Site Safety Officer will be responsible for enforcing all safety procedures

outlined in the Safety Plan.

3.5 GROUNDWATER COLLECTION PROTOCOLS

Approximately 10 liters of groundwater will be pumped from MW-4 (upgradient) into one-

liter glass bottles for use in the partitioning tests. The well will be first purged of a

minimum of three well volumes. A sample for total and dissolved organic carbon analysis

will be prserved with sulfuric acid. The sample for dissolved organic carbon will be filtered

prior to preservation.

1091.wr 3-6

Approximately 5 liters of groundwater from MW-11A will be collected by bailer to minimize

the loss of volatile organics. Purge water (at least three well volumes) from this well will

be collected and transported to the on-site air stripper for treatment. An oil/water interface

probe will be used to detect any pure phase material in the well. A clear bailer will also

be used to detect the presence or absence of any pure phase material in the sample from

MW-11A. If a non-aqueous phase is present, a sample will be collected from MW-11B

instead of MW-11A.

i09i.wr 3-7

SECTION 4

TEST APPARATUS

The test equipment that will be utilized in the soil/water partitioning studies are a bottle

extraction vessel and an agitation apparatus. This equipment is used in EPA's Method 1311

Toxicity Characteristic Leaching Procedure (TCLP), whic^ is included in this plan as

Appendix B.

The bottle extraction vessel is described in 40 CFR 261 Appendix II 4.2.2. Since at least

one liter of extract will be required for PCDD/PCDF analysis, a one-gallon borosilicate

glass bottle will be used. Because VOCs will be present in several of the tests, the tests will

be conducted with minimal headspace. Minimizing the loss of volatiles is most critical for

test case 2b. The zero headspace extraction apparatus (see Appendix B) will be used for

the TCLP tests on VOCs.

The filtration device for the bottle extraction vessel is discussed in 40 CFR 261 Appendix

II 4.3.2. This device will be any filter holder capable of supporting a glass fiber filter and

able to withstand the pressure needed accomplish the separation. A glass fiber filter that

meets the specifications in 40 CFR Appendix II 4.4 will be used. The filter diameter is 47

mm and the permissible effective pore size is 0.6 to 0.8 um.

The agitation apparatus is described in 40 CFR 261 Appendix II 4.1. This apparatus must

be capable of rotating the extraction vessel in an end-over-end fashion at 30 ± 2 rpm.

1091.wr 4-1

SECTION 5

PARTITIONING TEST PROCEDURE

The soil/water partitioning studies will require extractions and a post-extraction analyses of

soils/sediments and leachates. Groundwater will be mixed in the bottle extraction vessel

with each of the soil/sediment samples to achieve an equilibrium distribution of each

constituent between the water and the soil/sediment. Both the soil/sediment and leachate

will then be analyzed for each constituent of interest. The procedure for the tests will be

as follows:

1. Conduct physical testing on soil/sediment sample as specified in Section 6.

2. Carefully transfer 100 grams (minimum) of the soil/sediment sample from itscontainer to the one-gallon extraction vessel.

3. Analyze groundwater for total and dissolved organic carbon.

4. Slowly add 2 kilograms of upgradient groundwater (MW-4) to the vessel, minimizingheadspace.

5. Close the extractor bottle tightly, secure it in a rotary agitation device, and rotate at30 +. 2 rpm for 18 +_ 2 hours. It is recommended that Teflon tape be used to ensurea tight seal.

6. Maintain ambient temperature at 23 ± 2°C during the extraction period.

7. Following the 18 +. 2 hours extraction, separate the material in the extractor vesselinto its aqueous and solid phases by filtering through the glass fiber filter.

8. Analyze the aqueous and solid phases for VOCs, SOCs, PCDD/PCDF, HCB, andalpha-BHC (and antimony in Test Case la) according to methods specified in Section6 (HCB is analyzed using the SOC analytical method).

9. Carefully transfer 10 grams of solid phase into a preweighed crucible for moisturedetermination. Weigh crucible plus moist soil. Dry soil until a constant weight isachieved and record the final weight.

1091.wr 5-1

Although the TCLP procedure allows for the release of excess pressure from the reactor

vessel if necessary, this step will not be warranted for the types of soil and contaminants

found at the Dover Chemical site and will not be performed.

1091.wr 5-2

SECTION 6

PHYSICAL AND CHEMICAL ANALYSES

6.1 PHYSICAL ANALYSIS

Soil and sediment samples will by physically characterized to classify each soil type. The

methods employed will be as follows:

Physical Characterization Method

Soil Classification by the Unified ASTM D2487

Soil Classification System (USCS)

Liquid/Plastic Limit ASTM D4318-84

Particle Size Analysis ASTM D421/0422

62 CHEMICAL ANALYSIS

The soil/water partitioning studies require extensive analytical support to generate reliable

data on chemical characteristics of the soil and leachate. Therefore, standard analytical

procedures that conform to guidelines issued by the U.S. Environmental Protection Agency

and detailed in the approved SAP and QAPP will be used.

GC/MS analysis methods will be utilized for both soil/sediment and leachate analyses. For

soil and sediment analyses, EPA SW846 Method 8280 will be used to determine the

presence of tetra-, penta-, hexa-, hepta-, and octachlorinated dibenzo-p-dioxins and

dibenzofurans. This method is described in Appendix B of the QAPP. EPA SW846

Methods 8240 and 8270 will be used for VOCs and selected SOCs (1,2-dichlorobenzene, 1,3-

1091.wr 6-1

dichlorobenzene, 1,4-dichlorobenzene, 1,2,4-trichIorobenzene, and HCB), respectively. The

presence of alpha-BHC will be determined using Method 8080. Method 3050 will be used

to test for antimony in soil and water, respectively.

Total and dissolved organic carbon in the mixing water will be analyzed in accordance with

EPA Method 415.1. Organic carbon in the soil will be measured using EPA Method 9060.

VOCs will be analyzed in accordance with EPA Method 624. Moisture content will be

determined using ASTM D2216.

The total number of analyses anticipated for each parameter is presented in Table 6-1.

The proposed TCLP samples, which will be conducted on the site-wide composite, soil from

Area G, soil from Area H, and canal sediments, will each be analyzed for the parameters

listed in Section 2, using the same methods provided above. TCLP tests for the VOCs will

be run using ZHE; therefore, two separate TCLP test procedures are required on the

soil/sediment from each location except the site-wide composite, for which the ZHE will

not be conducted.

SECTION 7

DATA ANALYSIS

Data derived from the soil/water partitioning studies will be used to calculate the individual

soil/water partition coefficients for tetra-, penta-, hexa-, and octachlorinated dibenzo-p-

dioxins and dibenzofurans, as well as for HCB, alpha-BHC, and antimony, if present. These

calculations are described in Section 7 and Appendix B of the "Plan for Soil/Water

Leaching Tests of Contaminated Soils." The values of both Kd and K^ will be calculated

for use in future transport modeling to determine cleanup levels for soil and sediments that

will not produce significant leaching of chemicals to groundwater.

The TCLP tests will yield waste extract concentrations which will be compared to the TCLP

regulatory levels or to the allowable constituent concentrations in waste extract (CCWE).•

The TCLP regulatory values are presented in Table 7-1.

QUALITY ASSURANCE

A duplicate sample will be analyzed after Test Case la on both the soil and water extract.

A matrix spike analysis will be performed on a TCLP sample for bias correction.

All applicable laboratory QA/QC protocols in the SAP and QAPP will be followed for the

soil/water partitioning studies. This will ensure adequate quality assurance for the

laboratory data generated.

Laboratory analysis and decoumentation will consist of the standard QA package, except for

the analysis of PCDD/PCDFs in water samples, which uses the high resolution analysis.

Primary Routes of Entry

Hexane may exert its effects through inhalation, skin absorption, and ingestion.

Industrial Exposure: Route of Exposure/Signs and Symptoms

Inhalation: Exposure can cause dizziness, numbness of extremities, andintoxication.

Eye Contact: Liquid and high vapor concentration can be irritating.

Skin Contact: Prolonged or repeated skin contact can cause irritation anddermatitis through defatting of skin.

Ingestion: Can cause gastrointestinal tract discomfort.

Effects of Overexposure

Hexane is a mild eye and mucous membrane irritant, primary skin irritant, centralnervous system depressant and neurotoxin. Acute exposure causes irritation, narcosis,and gastrointestinal tract irritation. Chronic inhalation causes peripheral neuropathy.No systemic toxicity has been reported.

Medical Condition Aggravated bv

Preclude from exposure those individuals susceptible to dermatitis.

Emergency pjryt Aid

Inhalation: Immediately remove to Afresh air. If not breathing, administerJnouth-to-mouth rescue breathing. If there is no pulse administercardiopulmonary resuscitation (CPR). Contact physicianimmediately.

Eye Contact: Rinse with copious amounts of water for at least 15 minutes. Getemergency medical assistance.

Skin Contact: Flush thoroughly for at least 15 minutes. Wash affected skin withsoap and water. Remove contaminated clothing and shoes. Washclothing before re-use, and discard contaminated shoes. Getemergency medical assistance.

Ingestion: Call local Poison Control Center for assistance. Contact physicianimmediately. Aspiration Hazard - Do not induce vomiting.

VI. Safety Measures and Equipment.

Ventilation: Adequate ventilation is required to protect personnel from exposureto chemical vapors exceeding the PEL and to minimize fire hazards.The choice of ventilation equipment, either local or general, willdepend on the conditions of use, quantity of material, and otheroperating parameters.

Respiratory: Use approved respirator equipment. Follow NIOSH and equipmentmanufacturer's recommendations to determine appropriate equipment(air-purifying, air-supplied, or self-contained breathing apparatus).

Eyes: Safety glasses are considered minimum protection. Goggles orface shield may be necessary depending on quantity of materialand conditions of use.

Skin: Protective gloves and clothing are recommended. The choice ofmaterial must be based on chemical resistance and other userrequirements. Generally, Buna-N offers acceptable chemicalresistance. Individuals who are acutely and specifically sensitiveto hexane may require additional protective equipment.

Hexane should be protected from temperature extremes and directsunlight. Proper storage of hexane must be determined based on

Bother materials stored and their hazards and potential chemicalincompatibility. In general, hexane should be stored in an acceptablyprotected and secure flammable liquid storage room.

Other: Emergency eye wash fountains and safety showers should be availablein the vicinity of any potential exposure. Ground and bond metalcontainers to minimize static sparks.

VII. Spill and Disposal Data.

Spill Control: Protect from ignition. Wear protective clothing and use approvedrespirator equipment. Absorb spilled material in an absorbentrecommended for solvent spills and remove to a safe location fordisposal by approved methods. If released to the environment,comply with all regulatory notification requirements. •

Waste Disposal: Dispose of hexane as an EPA hazardous waste. Hazardous wastenumber: DOOKIgnitable).

Field Operating Procedure. - FldOl - NOISE

Noise is defined as unwanted sound. Noise can causa sudden traumatic hearing loss,long fprm more slowly occurring sensory-neural hearing loss which is irreversible,disruption of comnunicatian and making of warning devices and alarms, increasedstress levels and effects on the cardie-vascular and nervous systems. These lattertwo effects nay occur at levels below that which cause damage to hearing and insituations where the conditions are more or less constant and daily.

OSHA regulations generally apply to 8 hour exposures and consider 85 dBA as an actionlevel for a Hearing Conservation Program.

Where feasible, noise «*pmKm> will be controlled by engineering controls. Wherehigh noise levels are encountered and where engineering controls are infeasible oruntil engineering controls can be •rirTl<gh*ri) hearing protection devices will beused for worker protection from noise induced hearing loss.

Some of the sources of noise on t »9»rt n» materials, construction and industrialsites of a magnitude to cause hearing «**"**y> are: compressor motors, drill nengine, hammer blows (from split spoon or other) , «.««n »•••««««"• motors, compressed air,

water, and heavy equipment. The list is not all inclusive.

Any sound level surveys indicating noise levels of 85 dBA or above, or, in theabsence of sound level measuring instrumentation, any noise/sound preventing normalvocal discussion between two individuals at arms length distance will dictate theneed for hearing protection.

Hearing protection will be afforded by either disposable ear plugs or ear muffs.Administrative time control is not an acceptable method for preventing noise exposuresince extreme noise for a short duration can cause severe, permanent hearing loss.

In addition to these protocols, WESTCN's Hearing conservation Program includesphysical examination and audiometric testing during annual po i monitoring.

The selection, use, maintenance and control of hearing protection is further definedin the WESTGN Personnel Protective Eguipment Program.
