Introduction Background The San José-Santa Clara Regional Wastewater Facility (legally and officially named the San Jose/Santa Clara Water Pollution Control Plant) is jointly owned by the Cities of the San José and Santa Clara and was first constructed in 1956 with a capacity of 36 million gallons per day (MGD).

The San José-Santa Clara Regional Wastewater Facility (Wastewater Facility) serves a population of approximately 1.5 million residents and has a service area of over 300 square miles, covering most of the metropolitan areas of Santa Clara Valley. Within this service area are the Cities of San José (the City), Santa Clara, Milpitas, Cupertino, Campbell, Los Gatos, Monte Sereno, Saratoga, and adjacent unincorporated areas. The tributary agencies, listed above, discharge to the Wastewater Facility under several interagency agreements, including: Sewage Treatment Plant Agreement of 1959, Master Agreement of 1983, and four amendments to the Master Agreement dated 1985, 1995, 2006, and 2009 respectively.

The Wastewater Facility is the largest advanced wastewater treatment facility in California and provides tertiary treatment, which includes nitrification, filtration, and disinfection. Expansion of the Wastewater Facility capacity from 143 MGD to 167 MGD was completed in August 1986. On December 18, 1986, the San Francisco Regional Water Quality Control Regional Board (Regional Board) certified the Wastewater Facility Average Dry Weather Influent Flow (ADWIF) design capacity at 167 MGD. With a replacement value of approximately $2 billion, this state-of-the-art, computer controlled facility is one of the community's most valuable assets. The City of San Jose’s Environmental Services Department is responsible for operating and maintaining the Wastewater Facility and the administration of the Pretreatment Program, as well as many of the pollution prevention programs included in the 2018 Annual Pollution Prevention Report. The Wastewater Facility has had a pretreatment program since 1964. This program was originally submitted to the Environmental Protection Agency (EPA) on December 2, 1980, and approved on January 21, 1983.

Wastewater Discharge Requirements The 2018 Average Dry Weather Effluent Flow (ADWEF) was 79.4 million gallons per day (MGD), well below the 120 MGD flow trigger for the nineteenth consecutive year.

The Regional Board adopted the Wastewater Facility's current National Pollutant Discharge Elimination System (NPDES) operating permit on September 10, 2014, and the Wastewater Facility has successfully maintained compliance with this permit’s discharge limits.

The last Pretreatment Compliance Inspection (PCI) was conducted on June 27-29, 2016 by a contractor, Tetra Tech, Inc. representing the EPA. The City responded to all findings in a report sent to the Regional Board and EPA on June 4, 2018 and in the 2018 First Semi-Annual Industrial User Pretreatment Report.

2018 Influent, Effluent, and Biosolids Monitoring Results

Summary of 2018 Monitoring Results A description of sampling procedures can be found in the Influent, Effluent, and Biosolids Monitoring Results section of the 2018 Second Semi-Annual Report. Appendix I presents the 2018 pretreatment program monitoring results in tabular form for the past five years (2014-2018). Appendix II contains graphical representations of the influent and effluent data.

Discussion of 2018 Influent Monitoring Results The following analyses for priority pollutants were performed on the Wastewater Facility’s influent during 2018:

Base Neutral Acids (BNA)

Di-n-octyl phthalate is used as a plasticizer for synthetic resins such as poly vinyl chloride (PVC) and elastomers such as medical tubing. Di-n-octyl phthalate is predominantly released to the atmosphere by the plastic product manufacturing industry and the transportation machinery manufacturing industry. Phenol is frequently found in industrial wastewater from its use in the manufacture of resins, plastics, adhesives and other commercial processes. Phenol is also found in cigarette smoke and auto exhaust as well as disinfectants and medicinal products. Diethyl phthalate is ubiquitous in the environment based on its many applications as a plasticizer as well as a solvent for cosmetics, personal care products and insecticides. It may enter the environment in air emissions, aqueous effluent, and solid waste products from manufacturing and processing plants. Para Cresol (4-Cresol) can be found in petroleum products, artificially produced from auto and diesel emissions, coal production wastewater, disinfectants, metal refining, and chemical manufacturing. P-cresol is not a listed CTR compound. Butyl benzyl phthalate (BBP) is a plasticizer used primarily in the production of vinyl flooring materials with minor amounts in household products. Other possible sources of BBP release to the environment are from its manufacture, distribution and from PVC blending operations.

Volatile Organic Compounds (VOCs)

Chloroform may enter the environment through its use as an industrial solvent, extracting reagent, cleaning agent and as a by-product from the chlorination of water, wastewater, and cooling water. Artificial or indirect sources of chloroform primarily originate as a chlorination by-product in water treatment, paper mills, and combustion of leaded gasoline. Toluene is used as a general purpose solvent, fuel additive, and chemical manufacturing constituent. Considerable amounts are discharged during the emissions, volatilization, storage, transport, and disposal of fuels and oils. Ethylbenzene enters the atmosphere primarily from emissions and exhaust connected with its use in gasoline. Releases to the environment include emissions, wastewater, leaks, and spills connected with its production and use in the manufacture of styrene and use as a solvent. Other emission sources of ethylbenzene include emissions from petroleum refining, vaporization losses and spills of gasoline and diesel fuel during storage, delivery and transit, auto emissions and cigarette smoke. Methylene chloride has a long list of industrial/commercial uses, including as a solvent in paint strippers and removers; as a process solvent in the manufacture of drugs, pharmaceuticals and film coatings; as a metal cleaning and finishing solvent in electronics manufacturing; and as an agent in urethane foam blowing. The manufacturing, processing, distribution, conditions of use and disposal of methylene chloride can result in releases to the environment.

Discussion of 2018 Biosolids Monitoring Results

The collection and subsequent analyses of this Wastewater Facility’s biosolids sampling was on August 2, 2018 with the detection of the following priority pollutants:

Base Neutral Acids (BNA)

Bis(2-ethylhexyl) phthalate (mg/Kg) Sample Date

DNQ3.4 August 2, 2018

Bis(2-ethylhexyl) phthalate is used as a plasticizer for polyvinyl chloride and other polymers and is likely to be released to air and water during production and waste disposal of these plastic products. Bis(2- ethylhexyl) phthalate is carried long distances when released to air and has a strong tendency to absorb to soil and sediments. All other BNA compounds measured during this period for the Wastewater Facility’s biosolids sample were reported as non-detect at the method detection limit.

Volatile Organic Compounds (VOCs)

All volatile organic compounds measured during this period for the Wastewater Facility’s biosolids sampling were reported as non-detect at the method detection limit.

Polychlorinated Biphenyls-Aroclors

All PCB Aroclors measured during this period were all reported as non-detect at the method detection limit for the Wastewater Facility’s biosolids sample.

Organochlorine Pesticides

4,4’-DDE (mg/Kg) Sample Date

0.033 August 2, 2018

4,4’-DDE (Dichlorodiphenyldichloroethylene) is a degradation byproduct of DDT (Dichlorodiphenyltrichloroethane), formed by dehydrohalogenation or loss of hydrogen chloride. DDT is a pesticide commonly used for insect control in the United States until it was banned by the Environmental Protection Agency (EPA) in 1972. The concentration of this substance measured in the Wastewater Facility’s biosolids sample was well below the Total Threshold Limit Concentration for 4,4’-DDE of 1.0 mg/Kg.

5 of 6

All other analytical results for organochlorine pesticides were reported as non-detect at the method detection limit.

Priority Pollutant Metals

Priority pollutant metals for this period were measured at concentrations characteristic of typical biosolids production at this Wastewater Facility. No priority pollutant metals were detected in amounts that would adversely affect Class B biosolids disposal options.

Discussion of Five Year Influent and Effluent Trends (2014-2018) Influent • Arsenic concentrations remained consistent with a mean of 2.22μg/L, median of 2.18μg/L, and a

standard deviation of 0.36μg/L.

• Cadmium concentrations were typically reported as DNQ values with an RL of 0.40μg/L. Cadmium’s calculated mean concentration was 0.19μg/L, median of 0.17μg/L, and standard deviation of 0.07μg/L.

Inspection, Sampling, and Enforcement Programs

This section of the annual report provides summaries of the frequencies and procedures for the City of San Jose’s (City’s) inspection and sampling program. Included are the following:

• Inspection and Sampling Frequency Criteria,

• Inspection Format Procedures, and

• Chain of Custody Procedures.

Inspection and Sampling Frequency Criteria This section summarizes the normal condition sampling and frequency criteria for different types of industrial users.

Inspection Format Procedures This section summarizes key elements required to perform different types of inspections.

Chain of Custody Procedures This section summarizes the chain of custody procedure to ensure the integrity of samples collected and analyzed by City inspection and laboratory personnel.

Enforcement Procedures This section details the enforcement procedures used by the City to ensure violations are enforced consistently.

2 of 7

Inspection and Sampling Frequency Criteria

To collect samples that are representative of an SIU’s variable discharge practices, the dischargers are designated into three groups which are based on discharge type: Consistent, Variable, and Extremely Variable. A consistent discharger would continue to sample with a frequency of semiannually. An SIU would be considered a Variable discharger if the following are all true.

• Discharge is more than 5000 GPD.

• Processes produce discharge that changes over time or days.

• Treatment of wastewaters does not include ion exchange, membrane or ultra filtration, or batch discharge.

• Discharger may treat concentrated baths.

A discharger that fits these criteria would be considered a Variable discharger, and sampled quarterly. Dischargers that are 40 CFR 437 facilities, which have large variability in their discharge, would be considered “Extremely Variable” and sample monthly.

The annual inspection and sampling frequency established for the three groups is summarized in the following table, entitled “Inspection and Sampling Frequency.”

Inspection Format Procedures

Permit Inspection A permit inspection is conducted as part of the permitting process. There are three parts to a permit inspection.

1. The first part involves reviewing the following:

a. Permit application, b. Previous permit, fact sheets, and permit applications, c. Information in the Environmental Enforcement Database Management System

(EEDMS), d. Industrial User (IU) compliance history with all applicable limits, and e. Other file information such as sample results, IU, and City correspondence, etc.

2. The second part involves discussing the permit application and pertinent documents with the IU during a scheduled inspection. IU interviews include the following elements, as applicable:

a. Reviewing the permit application with the IU and resolving any discrepancies, b. Verifying the correct name of the company, c. Identifying responsible contacts and their roles, particularly the executive officer, the

waste treatment operator, and sampling contacts, d. Reviewing hours of operation, shifts, number of employees, and future expansion

plans, e. Determining time periods used for data submittals, f. Reviewing flow data, both influent and effluent, g. Verifying flow and disposal data for mass and flow balances, h. Determining location and types of water sources, i. Determining location of all wastewater discharge points, j. Reviewing sanitary sewer connections and storm sewer routing, k. Reviewing sewer treatment plant fee status, l. Reviewing compliance status, m. Reviewing the processes listed for any production or treatment equipment changes

since the last permit was issued, n. Evaluating the treatment system, o. Reviewing the site plan and process equipment layout to identify sample points and

documentation of flow meter types and locations, p. Reviewing in-house monitoring practices, q. Reviewing hazardous materials plan and chemical inventory list, r. Reviewing Slug Plan, Spill Prevention Plan, and Containment Plan, where

applicable, s. Reviewing waste manifests, t. Reviewing pollution prevention strategies, and

4 of 7

u. Reviewing water efficiency strategies and applicability of the Water Efficient Technologies Program.

3. The third part involves the physical inspection of the IU facility. Permit inspections include the following elements, as applicable:

a. Inspecting products and wastewater generating processes and activities, b. Verifying compliance with previous permit conditions, c. Verifying that the layout of the facility, processes, and treatment equipment

correspond to the application, d. Reviewing pollution prevention and water efficiency measures, e. Verifying plumbing layout corresponds to application, f. Verifying that all connections to the sewer and storm drain correspond to application, g. Verifying that the sample points are in the correct location and meet the permit

requirements, h. Reviewing in house self monitoring records, i. Reviewing that the location of flow meters corresponds to application, j. Identifying flow meter primary and secondary device types, k. Reviewing all in house flow meter records, l. Inspecting chemical storage areas and waste storage areas for any chemicals not

listed on the application, m. Inspecting site for general housekeeping, and n. Inspecting site for stormwater issues.

Compliance Inspection A routine inspection to determine compliance status and to identify practices which may lead to noncompliance. Compliance inspections are normally not scheduled and are not as in depth as a permit or an annual inspection. Compliance inspections include the following elements, as applicable:

1. Interviewing the IU’s contact,

2. Reviewing the IU facilities for system and process improvements or change,

3. Reviewing with IU the facility’s compliance history and self monitoring reports,

4. Discussing programs on scheduled improvements of wastewater treatment systems and improved practices furthering compliance,

5. Reviewing records of wastes not discharged to the sanitary sewer,

6. Inspecting wastewater producing areas, noting and discussing practices that might lead to noncompliance and faulty equipment,

7. Inspecting wastewater monitoring equipment, noting and discussing any faulty equipment,

8. Reviewing all wastewater monitoring logs, noting and discussing any discrepancies,

9. Inspecting chemical and waste storage areas, noting and discussing any careless practices or spills,

5 of 7

10. Reviewing facility’s in-house self monitoring records, noting and discussing any discrepancies,

11. Inspecting sampling point and monitoring station and equipment, noting and discussing any bypassing or other compliance issues,

12. Reviewing IU’s industrial waste discharge permit and verifying that all permit conditions are being met,

13. Reviewing and signing off pH chart recorder, and

14. Collecting a sample if determined to be needed during the inspection. Ongoing compliance sampling is conducted by Assistant Environmental Inspectors and discussed in the Sampling Inspection Section

Annual Inspection These inspections are similar to the compliance inspections and include all the items above; however, they are more detailed and require more time to conduct. Often these inspections are scheduled in advance to allow the IU the ability to have all required materials and records prepared in advance to facilitate the inspection. In addition to the elements described for compliance inspections, annual inspections include the following elements, as applicable:

1. Reviewing in depth all of the IU’s files and the database prior to the inspection including the layout of the facility, the processes, the permit application, the permit, and fact sheet, the compliance history and the IU's Self Monitoring Reporting schedule,

2. Reviewing and verifying contact information,

3. Reviewing with IU hours of operation and number of shifts,

4. Discussing with IU any future expansion plans,

5. Reviewing all waste and storage records,

6. Reviewing with IU the facility flow diagram and facility layout for new processes or new equipment,

7. Inspecting facility processes for any bypasses, dilution streams, process and equipment changes, and documenting any changes not discussed previously,

8. Inspecting facility processes for dilution streams,

9. Inspecting wastewater treatment system and documenting any changes,

10. Inspecting and reviewing calibration of flow, pH monitoring, and other monitoring equipment,

11. Review pH chart recorder as applicable, noting and discussing any discrepancies and potential violations, and

12. Reviewing requirements for slug discharge plan by completing slug plan evaluation checklist or reviewing updates to existing slug discharge plan.

6 of 7

Enforcement Inspection An enforcement inspection is the same as a compliance inspection, but is targeted on determining the causes of violations discovered according to the Source Control Enforcement Response Plan. The purpose of these types of inspections is also to verify the responses to the violation including how the IU will prevent future violations.

Special Investigation Inspection A special investigation inspection is an inspection used to verify that adequate measures are being implemented to prevent violations of local, state, or federal regulations governing discharge due in response to a spill to the storm or sanitary sewer, emergency or other special matter, or in response to a complaint. This inspection is performed in response to a notification of a spill to the storm or sanitary sewer.

Sampling Inspection These inspections are performed by the Assistant Environmental Inspectors during routine sampling events conducted by the City. Sampling inspections include the following elements, as applicable:

1. Collecting compliance and revenue samples as required,

2. Checking samples for pH using pH meter and recording the results,

3. Recording pH from final pH meter and comparing to pH meter readings of sample collected,

4. Recording flow readings from flow meters and verifying last calibration date,

5. Recording results of last in-house testing with time and date,

6. Recording any observations of sample point and sampling equipment,

7. Recording any abnormalities observed in effluent conditions, and

8. Recording any abnormalities observed in treatment system.

Closure Inspection These inspections are performed when a discharger is in the process of closing. Several inspections may be required to review the company’s progress toward closure. These inspections may include the following elements, as applicable:

1. Verifying removal of all process equipment from the facility,

2. Verifying removal of all process chemistries from the facility,

3. Reviewing waste manifests for verifications that all waste has been hauled from the facility,

4. Verifying and recording the date of last discharge to sanitary sewer,

5. Recording any influent water meter readings, and

6. Verifying that IU has filed a closure plan with the fire department.

7 of 7

Chain of Custody Procedures

All sampling performed by City personnel involves the use of a chain of custody record. The chain of custody record is part of the Laboratory Analysis Request form. This form indicates who took the sample, who witnessed the taking of the sample, and to whom the sample was released. It is intended to document every person that has had access to the sample. Samples are always in the secure custody of the sampling person until released to the laboratory. Once in the laboratory, samples are held in a locked area, accessible only to the last person signing for the samples.

Enforcement Procedures

The Pretreatment Program’s Enforcement Response Plan (ERP) was prepared in accordance with EPA’s Guidance for Developing Control Authority ERPs. The latest revision of the ERP was included with the 2009 Annual Report. The Pretreatment Program continues to follow the guidelines of this ERP.

Updated List of Regulated Significant Industrial Users

This section consists of three tables summarizing the changes made to the list of Significant Industrial User (SIU) facilities that discharge to the Wastewater Facility. For the purpose of this report, Non-Significant Categorical Industrial Users (NSCIU) and Zero Discharge Categorical Users (ZDC) are being reported with SIUs. As of December 31, 2018 there were 134 SIUs discharging to the Wastewater Facility. These facilities were classified as SIUs because they are either classified as having a categorical industrial user (CIU) process, categorized as such by our program, or have a discharge that is over 25,000 gallons per day. The following describes each table:

• Updated List of Regulated SIUs – 2018 contains a complete listing of all SIUs as of December 31, 2018. Each SIU is listed in alphabetical order by facility name. The table also includes the discharger’s permit number, address, and reason why each discharger is classified as an SIU.

• Deleted SIUs – 2018 lists all SIUs that are no longer permitted, or are no longer an SIU. Each SIU listed shows the permit number, the discharger’s address, the federal category under 40 CFR for the discharger where applicable, and a reason that the discharger was deleted or is no longer an SIU.

• Newly Permitted SIUs – 2018 lists all SIUs that received a new permit in 2018, the new permit number, the discharger’s address, and the federal category under 40 CFR for each SIU where applicable.

The Combined Wastestream Formula (CWF): Ct = (ΣCiFi) x (Ft-Fd) (ΣFi) (Ft)

Where, Ct = Alternative concentration limit for the combined wastestream for TTOs Ci = Categorical pretreatment standard concentration limit under 40 CFR 469: 1.37 mg/l for TTOs Fi = Regulated Semiconductor flowstream, average daily flow: 124,000 – 7,500 = 116500 gpd Fd = Dilution stream: 7,500 gpd Ft = Average total flow through sample point: 124,000gpd

Ct = (1.37 mg/l) (116,500) x (124,000 gpd – 7,500 gpd)

(116,500 gpd) 124,000 gpd

Ct = 1.37 x 0.9395

Ct = 1.287 mg/l ~ 1.29 mg/l

Therefore, new modified TTO limit at sample point 01 = 1.29 mg/l

Combined Wastestream Formula Calculations for Coherent Federal TTO Limit

Federal TTO Limit for Semiconductor Manufacturing (40 CFR 469.12(a) = 1.37 mg/l

Semiconductor Manufacturing Flow Rate = 2,769 gallons per day

Laser Manufacturing Dilution Flow Rate = 7,555 gallons per day

Total Flow = 7,555 + 2,769 = 10,324 gallons per day

Coherent Federal TTO Limit = (Federal TTO Limit for Semiconductor Manufacturing * Semiconductor Manufacturing Flow) / Total Flow

Coherent Federal TTO Limit = (1.37 mg/l x 2,769 gal per day) / 10,324 gal = 0.36 mg/l

INTA Technologies, LLC

Permit No. SC-307B

- Combined Wastestream Formula (CWF) -

The Combined Wastestream Formula (CWF): Ct = (ΣCiFi) x (Ft-Fd) (ΣFi) (Ft)

Where, Ct = Modified concentration limit for the combined wastestream for CN Ci = Categorical pretreatment standard concentration limit for parameter (i) Fi= (i) wastewater flow Ft=Total wastewater flow Fd=Dilution wastewater flow

Applying the CWF to one regulated parameter with the same limit in two waste streams:

Ct1 = [(ΣC1F1)/(ΣF1)] x [(Ft-Fd)/(Ft)] = [(C1ΣF1)/ (ΣF1)] x [(Ft-Fd)/(Ft)] = C1 x [(Ft-Fd)/(Ft)]

- CWF Limit Calculation for Dmax -

Under 40 CFR 433.17(a): the daily concentration limit is Ci = 1.2 mg/l for CN Fd = Dilution = noncyanide average daily flow regulated 40 CFR 433.17(a) = 95 gpd Ft = Average total process flow through both the sample points: 123.5 gpd

For the metal finishing metal and cyanide limits the semiconductor manufacturing wastewater is considered an unregulated stream since those pollutants are not regulated by a categorical standard from that category. The unregulated semiconductor manufacturing discharge is assigned the same limits as metal finishing discharges for use in the combined wastestream formula for metals and cyanide. For the TTO limit, the limits from each category are combined into the final limit based on the standard categorical limits and the discharge flows.

Executive Summary

This report presents the City of San José’s (City) technical evaluation of the City’s existing local limits to determine if modifications to these limits are needed to maintain compliance with regulatory requirements applicable to the San José-Santa Clara Regional Wastewater Facility (Facility), to protect worker health and safety, and to safeguard Facility and collection system infrastructure. Additional factors that were considered in the assessment of the City’s existing local limits included special National Pollutant Discharge Elimination System (NPDES). The evaluation process was based on the maximum allowable headworks loading (MAHL) method described in the July 2004 United States Environmental Protection Agency (EPA) Local Limits Development Guidance Manual (Guidance Manual).

The consulting firm EEC Environmental, located in Orange, California, participated in the review for adequacy of the local limits by providing technical assistance and reviewing drafts of this report.

The conclusion of this evaluation was that no updates to the City’s local limits are required at this time.

Local Limits Process

The local limits evaluation process prescribed in the Guidance Manual is a mass-based approach. First, potential pollutants of concern (POCs) are established based on regulatory and operational requirements. Next, POC allowable headworks loadings (AHL) that achieve regulatory and operational objectives are calculated based on Facility performance data. The smallest AHL for each POC is the POC’s MAHL. Finally, for each POC, the ratio of MAHL to the Facility’s actual influent loading is compared with Guidance Manual criteria to determine whether new local limits should be promulgated for POCs that are not currently regulated, and whether existing local limits should be modified.

If the evaluation determines that any local limit needs to be updated, then for each POC requiring a new or revised local limit, the maximum allowable industrial loading (MAIL) is determined by subtracting Facility residential and commercial loadings from the MAHL. The MAIL for each POC is then allocated among regulated industrial users to establish the POC’s local limit. The traditional approach to allocate the MAIL among regulated industrial users is to divide the MAIL by the average industrial flow to derive a uniform concentration limit. Since this evaluation determined no updates to local limits were required at this time, MAILs were not calculated.

Selecting POCs

The Guidance Manual lists 15 mandatory POCs and recommends reviewing the NPDES Permit and existing local limits for other potential POCs. The following regulatory standards were reviewed for this evaluation:

• Facility’s NPDES Permit No. CA0037842, Order No. R2-2014-0034 • California Toxics Rule (CTR) water quality criteria (WQC) (2000), • National Toxics Rule (NTR) WQC (1999), • Federal Sewage Biosolids Standards (1995), • Threshold Inhibition Values for Activated Sludge, Nitrification, and Anaerobic Digestion

(1987), and • California State Hazardous Waste Threshold Values (2004).

Collecting Influent, Effluent, and Biosolids Data

Evaluating the performance of current local limits and developing MAHLs for POCs requires various types of pollutant information. Most of the concentration data required were readily available from

2018l San José-Santa Clara Regional Wastewater Facility Industrial Wastewater Local Limits Update

EXECUTIVE SUMMARY

samples collected by the Facility for regulatory compliance monitoring. The data assembled for this evaluation included:

• Influent, effluent, and biosolids concentration data for 2013 through June 2017, • Facility influent, effluent and South Bay Water Recycling flow data for 2013- 2017,

Summarizing the Results

Information on current influent and effluent concentration and loading for the POCs was compared to regulatory limitations and MAHLs to determine if any local limits required modification or addition. The Facility was in compliance with all NPDES requirements during the previous five-year period used for the evaluation. The MAHLs calculated during the evaluation were under the threshold levels for a more rigorous local limit review as identified in the Guidance Manual. The existing local limits remain protective of Facility operations, the Facility and collection system infrastructure, the health of Facility and collection system workers, and the public. No changes to the existing local limits are recommended.

The Facility is undergoing a large, multi-year capital improvement program to upgrade and modernize the equipment and operations, which may result in changes to the treatment results. A more detailed reevaluation of the local limits will be performed when the operational changes are complete.

Table E-1 summarizes the existing local limits and the recommendation to leave them unchanged.

1.0 Introduction This report presents the City of San José’s (City) technical evaluation of the City’s existing local limits to determine if modifications to these limits are needed to maintain compliance with regulatory requirements applicable to the San José-Santa Clara Regional Wastewater Facility (Facility), to protect worker health and safety, and to safeguard Facility and collection system infrastructure. Additional factors that were considered in the assessment of the City’s existing local limits included special National Pollutant Discharge Elimination System (NPDES). The evaluation process was based on the maximum allowable headworks loading (MAHL) method described in the July 2004 United States Environmental Protection Agency (EPA) Local Limits Development Guidance Manual (Guidance Manual).

The local limits evaluation process prescribed in the Guidance Manual is a mass-based approach. First, potential pollutants of concern (POCs) are established based on regulatory and operational requirements. Next, POC allowable headworks loadings (AHL) that achieve regulatory and operational requirements are calculated based on Facility performance data. The smallest AHL for each POC is the POC’s MAHL. Finally, for each POC, the ratio of MAHL to the Facility’s actual influent loading is compared with Guidance Manual criteria to determine whether new local limits should be promulgated for POCs that are not currently regulated and whether existing local limits should be modified. Note that the “anti-backsliding” concept associated with NPDES permits does not apply to local limits. Local limits may be modified to be more or less stringent or eliminated entirely based on the results of the evaluation.

For each POC requiring a new or revised local limit, the maximum allowable industrial loading (MAIL) is determined by subtracting Facility residential and commercial loadings from the MAHL. The MAIL for each POC is then allocated among regulated industrial users to establish the POC’s local limit. The traditional approach to allocate the MAIL among regulated industrial users is to divide the MAIL by the average industrial flow to derive a uniform concentration limit.

The consulting firm EEC Environmental, located at 1 City Boulevard West in Orange, California, participated in the development of the local limits by providing technical assistance and reviewing a draft of this report. 1.1 Previous Local Limits Evaluation The City routinely assesses the effectiveness of its source control program through evaluations of influent, effluent, and biosolids-loading data as described in its annual Industrial User Pretreatment Compliance Reports. In addition, the City must evaluate local limits during the term of each Facility NPDES Permit to ensure that pretreatment and source control activities continue to protect the San Francisco Estuary, the Facility operations, and the wastewater collection system, as well as comply with state and federal environmental regulations.

The City conducted the last comprehensive technical evaluation of industrial local limits using data from 2008 to 2012 that was summarized in a report titled 2013 San Jose/Santa Clara Water Pollution Control Plant Industrial Wastewater Discharge Local Limits Update. This study concluded that there were no pollutants of concern above the MAHL thresholds, and therefore no modifications to local limits were required. The last changes to the local limits were made in 2007 based on recommendations from a technical evaluation of local limits as summarized in a report titled, 2006 Industrial Waste Discharge Local Limits Update. The local limits for xylene and manganese were removed and the local limit for selenium was decreased to match the California hazardous waste STLC limitation for consistency. The City also simplified copper and nickel local limits by replacing the existing Group 1, 2, and 3 discharger types of limits and implementing a simpler two limit system for copper and nickel based on the discharge volume. IUs discharging less than 1,000 gpd are classified as “Low Flow Dischargers” and those discharging 1,000 gpd or more are classified as “Standard Dischargers.”

2.0 The San José-Santa Clara Regional Wastewater Facility The Facility is in the early stages of a multi-year capital improvement program. Much of the work is replacing older equipment with new more reliable and efficient units. Some of the processes may be changed significantly when the upgrades are complete, such as biosolids handling. Another technical evaluation of the City’s local limits may be necessary after the changes are complete to ensure the local limits remain protective. The current Facility wastewater treatment process is comprised of the following steps: preliminary treatment, primary treatment, secondary treatment, filtration, disinfection, and disinfectant removal, as shown in “Figure 1: Process Schematic”. The Facility treats its primary and secondary sludge prior to disposal through sludge dewatering, anaerobic digestion, and lagoon storage. The Facility also has offline flow equalization basins with a total storage volume of 16-million gallons to store wastewater during peak flow periods. Below is a short description of these treatment processes and facilities. 2.1 Preliminary Treatment Preliminary treatment consists of four climber bar screens to remove large debris from the raw sewage and two grit removal chambers. Effluent from the grit removal process flows into a raw sewage wet well for pumping into the primary sedimentation tanks.

Raw sewage enters the Facility from San José through a 103-inch pipe, from Santa Clara through a 78- inch pipe, and from Milpitas through a 36-inch force main. These lines tie in at the inlet control structure located just south of the headworks structure. Four influent sluice gates regulate Facility influent to the four climber bar screens.

The mechanically cleaned bar screens remove large objects (e.g., rags, sticks, paper items, etc.) from the influent. Debris removed from screens is lifted onto a dual-direction conveyor belt. During normal operation, screened items are conveyed to a hopper then lifted to a dewatering press via a screw conveyor. The screenings are dewatered to approximately 50 percent solids, and then discharged into a dump bin. Periodically, this bin is dumped into a larger bin for landfill disposal.

The raw sewage then flows to the aerated grit chambers, which uses compressed air to create a rolling motion within the flow, allowing heavy inorganic material and some organic material (e.g., sand, rocks, coffee grounds, eggshells, etc.) to settle out of the wastewater. The settled material is then screw-conveyed to a cyclone separator that uses the properties of a vortex to remove grit from the raw sewage.

From the aerated grit chambers, the sewage flows to the detritors, which also remove grit by gravity settling under low velocity. The baffle obstructions in the tank reduce flow short-circuiting, thereby eliminating localized higher flow velocities. The settled grit is directed to a sump using mechanical arms fitted with sweepers. The grit in the sump is pumped by one of two pumps to one of two cyclone separators. Effluent from the preliminary treatment system is pumped to the primary settling tanks. 2.2 Primary Treatment Following preliminary treatment, wastewater is pumped into primary clarifiers. The Facility has 24 primary clarifiers with a total surface area of 140,600 square-feet (ft2) and a design peak overflow rate of 1,930 gallons per square foot per day (gal/ft2/d). The primary clarifiers remove floatable material and settled material. The primary treatment process includes pumping of the floatable and settled solids to scum treatment and solids processing areas, respectively. The diurnal flow of primary influent dictates the surface loading rates on the primary settling tanks.

In any sedimentation tank, those materials that have a higher specific gravity than the sewage will

2.0 SAN JOSE-SANTA CLARA REGIONAL WASTEWATER FACILITY

tend to settle, and floating material and grease with a lower specific gravity will tend to rise. As the sludge collectors rotate through the bottom of the sedimentation tanks, the collectors push settled solids or sludge to the tank hopper where it is removed by raw sludge pumps for sludge treatment. As the chain and flight collectors rotate over the surface of the tank, floating material is pushed toward the skimming mechanism (scum pipe drive and scum trough). This material is removed by the automatic skimming device and conveyed to a scum well, where it is discharged to a scum pit.

The preliminary and primary treatment processes remove approximately 98 percent of all settleable solids, 40 to 60 percent of all suspended solids, and 20 to 50 percent of all biochemical oxygen demand (BOD). The remaining BOD and colloidal and non-settleable solids are conveyed to the Secondary Treatment Process for biological nutrient removal (BNR). 2.3 Secondary Treatment In 1996, the Facility’s secondary treatment was converted from separate activated sludge and nitrification processes to a BNR process. The BNR process involves the removal of ammonia (NH3) and BOD in the same aeration basins. A two-stage step feed aeration process achieves BNR by routing primary effluent through the former secondary and nitrification systems in parallel (now all considered secondary activated sludge systems). The secondary activated sludge system has 16 aeration basins divided into two batteries (A and B); each battery consists of eight aeration basins. These eight rectangular aeration basins are further divided by baffles into four equal-sized compartments (quads).

The first quad is anaerobic for fermentation to increase volatile fatty acids for improved phosphorous removal. The second quad is aerobic for ammonia nitrification, which is the sequential biological oxidation of ammonia to nitrite (NO2), and then to nitrate (NO3). The third quad is anoxic and receives 40% of the primary treated wastewater to promote denitrification, which is the biological reduction of nitrate to nitrogen gas (N2), and reduction of soluble BOD. The final quad is aerobic and promotes oxidation of BOD and ammonia from the 40% portion of the primary effluent that enters quad 3 and maintains sufficient dissolved oxygen in the mixed liquor

The effluent from the aeration basins flows to clarifiers for solids removal via settling. The Facility has 26 secondary clarifiers, with a total surface area of 227,500 ft2and a design peak overflow rate of 880 gal/ft2/d. The majority of settled solids are returned to the aeration basins, and a fraction is wasted to the dissolved air flotation tanks for solids processing. Secondary effluent from each clarifier is collected in the effluent conduit and transported by gravity to the filter influent pump station from which it is pumped to the dual-media filters. 2.4 Filtration Each dual-media filter bed consists of a tile under drain system installed on the filter floor. The dual- media filter has layers of silica gravel, silica sand, and one layer of anthracite coal—all supported by the under drain system. Total filter surface area is 22,080 ft2, and the single filter surface area is 1,380 ft2. The average designed filter flow rate is 158 million gallons per day (mgd). Backwash water loaded with debris from filter cleaning is routed to a basin for flow equalization before alum addition, flocculation, and settling. The chemically conditioned and settled backwash water is then pumped to the chlorine contact tanks for disinfection and discharge with the final effluent. 2.5 Disinfection Effluent from the dual media filters is disinfected using chloramination by adding sodium hypochlorite and ammonia into the chlorine contact chamber. Disinfection is followed by dechlorination using sodium bisulfite solution. When required, caustic soda is added following dechlorination for pH adjustment. The effluent discharges to the Artesian Slough and to the South San Francisco Bay, “Figure 2: Facility Effluent” shows a photo of the discharge to the slough.

2.6 Solids Processing The dissolved air floatation system receives sludge from the primary sedimentation basins and wasted activated sludge from the secondary clarifiers. Dissolved air flotation further thickens the sludge before it enters the anaerobic digesters. Supernatant from dissolved air floatation returns to headworks.

Digested sludge from the anaerobic digesters is pumped to 28 active sludge lagoons. The lagoons are grouped in four blocks, with each block containing from six to eight lagoons. It normally takes one year to fill a lagoon block. While one block is being filled, one block is emptied, and the other two blocks are stabilizing the sludge to Class A quality. After two to three years of stabilization, dredged sludge is pumped to drying beds where it takes about three to four months to dry. Once dried, the sludge is stockpiled for transportation by outside contractors to a beneficial reuse site.2

The sludge is currently used as cover for a nearby landfill.

2.7 Operational Issues and Compliance Between 2013 and 2017 there were no operational issues at the Facility due to influent toxicity. The Facility has been in compliance with its regulatory requirements for conventional pollutants and toxic substances since its most recent reissuance of NPDES Permit Number CA-0037842, Water Board Order R2-2014-0034 in 2014.

Grease blockages have occasionally occurred in the collection system. These blockages are assumed to have been caused by residential and restaurant grease. The City has a restaurant inspection program to educate restaurant and other food facility operators about proper grease disposal and to enforce maintenance requirements. All new restaurants and food service facilities are required to

complete a plan check to ensure the proper installation of grease removal devices.

Hydrogen sulfide odor is also a potential issue for the collection system. Most sulfide production results from long flat sewer lines in residential areas entering drop manholes, causing release of sulfide gas into the atmosphere. The City has installed two biofilters to control hydrogen sulfide emissions and continually treats one of the main trunk lines with ferrous chloride to precipitate the sulfide from solution.

“Table 2: Annual 2013 to 2017 Facility Influent, Final Effluent, and South Bay Recycled Water Flow Rates” summarizes the flow rate data used for this evaluation. This local limit evaluation used the 2013-2017 annual average Facility influent flow rates to calculate the applicable allowable headworks loadings and daily pollutant loading.

3.0 MAHL Analysis Process for Evaluating Local Limits The present evaluation of industrial local limits was based on criteria described in the Guidance Manual. The steps of this evaluation process included:

• Developing POCs criteria, • Selecting POCs, • Collecting influent, effluent, and biosolids data, • Calculating removal rates for POCs, • Calculating AHLs for each POC, • Determining the MAHL for each POC, • Identifying POCs requiring new or revised local limits, if any.

The following sections describe each of these steps in more detail. 3.1 Developing POCs Criteria The primary objective of this evaluation was to develop local limits that protect the collection system, the wastewater treatment facility, the health and safety of personnel, and the environment. The following regulatory standards were reviewed for this evaluation:

• Facility’s NPDES Permit No. CA0037842, R2- Order No. R2-2014-0034 • California Toxics Rule (CTR) water quality criteria (WQC) (2000), • National Toxics Rule (NTR) WQC (1999), • Federal Sewage Biosolids Standards (1995), • Threshold Inhibition Values for Activated Sludge, Nitrification and Anaerobic Digestion (1987), and • California State Hazardous Waste Total Limit Concentrations (TTLC) and Soluble Threshold Limit Concentration (STLC) Values (2004).

3.2 Selecting POCs The following sections describe how toxic and conventional pollutants were evaluated for inclusion on the final list of POCs to be examined through the MAHL process. A POC is any pollutant that might reasonably be expected to be discharged to the Facility in sufficient amounts to cause pass through or interference, compromise biosolids quality, cause problems in its collection system, or jeopardize worker safety. Pollutants contributing to or known to cause operational problems are also considered POCs even if the pollutants are not currently causing NPDES permit violations. The methods used to determine POCs should account for daily fluctuations in the Facility’s pollutant loadings and data availability.

The POCs were examined by evaluating current influent and effluent concentration information for regulatory compliance. If concentration data were below the minimum detection level for both influent and effluent, then the local limits evaluation process could not be followed directly for these contaminants. EPA recommends that a POTW conduct a screening analysis for any pollutants determined to be potential POCs. Although a contaminant may initially be considered a potential POC, a POTW may determine, based on the pollutant’s concentration and on other data from IUs and commercial dischargers, that the pollutant need not be selected as a POC for the full headworks analysis. 3.2.1 EPA-Recommended POCs EPA has identified 15 pollutants often found in POTW sludge and effluent that it considers potential POCs. EPA recommends that each POTW, at a minimum, screen for the presence of these 15

2-2

3.0 MAHL ANALSISI PROCESS FOR EVALUATING LOCAL LIMITS

pollutants using data on industrial user (IU) discharges and collected from samples of POTW influent, effluent, and sludge. These “National” POCs are: • Arsenic, • Cadmium, • Chromium, • Copper, • Cyanide, • Lead, • Mercury, • Molybdenum, • Nickel, • Selenium, • Silver, • Zinc, • 5-day Biochemical Oxygen Demand, • Total Suspended Solids, • Ammonia. Cadmium, chromium, copper, lead, nickel, and zinc are recommended for evaluation because of their widespread occurrence in POTW influents and effluents at concentrations that may warrant concern. Arsenic, cyanide, and silver are not as widespread in POTW influents, but these constituents have particularly low biological process inhibition and/or aquatic toxicity values. Cyanide is also a concern due to its potential to develop toxic sewer gases. Molybdenum and selenium are of potential concern because they are regulated through the federal biosolids regulations. Selenium is also of special interested in the San Francisco Bay Area due to its predominance for bioaccumulation. The EPA recommends including the conventional pollutants BOD, ammonia, and TSS because many POTWs nationwide have issues with these pollutants. The Guidance Manual considers ammonia as a “conditional” POC for POTWs that accept non-domestic sources of ammonia. 3.2.2 Reasonable Potential POCs The Guidance Manual recommends that any contaminant that has a “reasonable potential” to be discharged in amounts that could exceed water quality criteria should be considered a POC and evaluated accordingly. However, a POTW does not have to develop a local limit for every pollutant for which there is a water quality standard or criterion. A reasonable potential analysis (RPA) completed in 2013 as part of the NPDES Permit reissuance process found that the following constituents had a “reasonable potential” to cause or contribute to a water quality exceedance:

• Copper, • Nickel, • Cyanide, • Dioxin TEQ, and • Indeno(1,2,3-cd)Pyrene • Copper Nickel, and Cyanide are already included in the POC analysis. Mercury and PCBs are

regulated by NPDES Permit CA0038849, which implements a TMDL for Mercury and PCBs in San Francisco Bay. Mercury is included in the POC analysis. The following discusses the reasonable potential and the appropriateness of local limit control for Dioxin TEQ, Indeno(1,2,3-cd)Pyrene, and PCBs.

3.2.2.1 Dioxins-Toxicity Equivalent and PCBs Dioxins are a family of 75 chemically related compounds commonly known as chlorinated dioxins. One of these compounds is 2,3,7,8-TCDD (tetrachlorodibenzo-p-dioxin) and it is the most toxic form

2018 San José-Santa Clara Regional Wastewater Facility Industrial Wastewater Local Limits Update

2-3

3.0 MAHL ANALSISI PROCESS FOR EVALUATING LOCAL LIMITS

of dioxin and the most studied. TCDDs are not intentionally manufactured by industry except for research purposes. TCDDs (mainly 2,3,7,8-TCDD) may be formed during the chlorine bleaching process at pulp and paper mills. TCDDs are also formed during chlorination by waste and drinking water facilities. By far, the greatest unintentional production of TCDDs occurs via various combustion and incineration processes, including all forms of waste incineration (municipal, industrial, and medical); many types of metal production (iron, steel, magnesium, nickel, lead, and aluminum); and fossil fuel and wood combustion.1

Although 2,3,7,8-TCDD has never been detected in Facility effluent, other dioxin congeners have been detected using research-based low-level monitoring techniques. Each of the cogeners has a toxicity equivalency factor (TEF) that is multiplied by that cogener’s result to derive a toxicity concentration “equivalent” to 2,3,7,8-TCDD . The total of these adjusted cogener concentration is referred to as the “dioxin TEQ” value, and is compared with the 6.3 X 10-5 μg/L interim monthly average limit for dioxin –TEQ specified in order R2-2009-0038. In 2010, the 2009 Permit limit was amended by Order R2-2010-0054 (new “Attachment G”) to incorporate cogener bioaccumulation equivalency factors (BEFs) in addition to the TEFs. For each cogener, the analytical result is multiplied by both the TEF and BEF, and the sum of these adjusted concentrations determines the dioxin-TEQ value. The TEQ values reviewed for this local limit update were well below the Permit’s dioxin TEQ limit.

In accordance with the Mercury and PCBs Watershed Permit, Permit # CA0038849, reissued as Order No. R2-2012-0096, PCBs are measured semi-annually as total aroclors using EPA method 608 for regulatory compliance. PCBs were not detected using this method.

In addition, a 2000 City report entitled Selected Organics Source Investigation – Program Report described an evaluation of industrial processes that could generate and discharge organochlorine pesticides, PCBs, or dioxin to the Facility. These processes include pesticide manufacturing, incineration with fume scrubbers, and paper production. The report concluded that no known industrial facilities that could generate organochlorine pesticides, PCBs, or dioxin were located in the Facility service area.2 This analysis remains applicable today since the composition of the industrial community has not changed appreciably from that in 2000. Appendix A lists the industrial users in the service area as of July 31, 2018. 3.2.2.2 Indeno(1,2,3-cd)Pyrene The most stringent applicable Indeno(1,2,3-cd)Pyrene water quality criterion is the 0.049 ug/L CTR criterion for protection of human health. The 2014 Order found reasonable potential and thus established effluent limitations for Indeno(1,2,3-cd)Pyrene because the ambient background concentration (0.078 μg/L) exceeds this CTR criterion. The maximum Facility effluent data was (0.009 ug/L), well below the most stringent water quality criteria. In addition, it would not reasonably be expected that Indeno(1,2,3-cd)Pyrene would lead to interference, biosolids contamination, collection system problems, or increased worker jeopardy. Therefore, Indeno(1,2,3-cd)Pyrene is not included for further analysis. 3.2.3 NPDES Permit Limit POCs Conventional pollutants with limitations in the NPDES Permit should be considered when evaluating local limits. The following conventional pollutants from the 2014 NPDES Permit have already been identified above as POCs: BOD, Ammonia and Totals Suspended Solids. The following presents a discussion of the remaining conventional pollutants for a determination of their inclusion as a POC: 1 Toxicological Profile for Chlorinated Dibenzo-p-dioxins (CDDs), U.S. Department of Health and Human Services, Public Health Service, Agency for Toxic Substances and Disease Registry (ATSDR), http://www.atsdr.cdc.gov/toxprofiles/tp104- c4.pdf, page 369, December 1998 2 “Selected Organics Source Investigation – Program Report”, July 2000 CBS Report

3.0 MAHL ANALSISI PROCESS FOR EVALUATING LOCAL LIMITS

3.2.3.1 Oil and Grease The NPDES permit limits for oil and grease are 10 mg/L as a daily maximum and 5 mg/L as a monthly average. The influent is rarely analyzed for oil and grease concentration as this parameter has not been considered a POC in the past, and all effluent data were found to be well below the minimum reporting level of 5 mg/L between 2013 and 2017. The current 150 mg/L oil and grease industrial limit functions to protect the collection system from flow obstructions. The City’s current local limit is deemed satisfactory since it has protected the collection system from unfavorable effects due to oil and grease contamination. Therefore, further review of oil and grease for evaluation as an industrial local limit is not warranted at this time. In addition, oil and grease would not reasonably be expected to result in pass through, interference, biosolids contamination, or increased worker jeopardy. 3.2.3.2 Turbidity The NPDES permit limit for turbidity is 10 NTUs as an instantaneous maximum. The Facility effluent has exhibited turbidity values significantly below this limitation between 2013 and 2017 with effluent concentrations characterized by a mean value of 1.1 NTU and a maximum value of 3.6 NTU. In addition, the City has a narrative “colored matter” sewer use ordinance limitation that has proven protective of the collection system and treatment Facility. Section 15.14.620 of the San José Municipal Code reads:

No person shall discharge, cause, allow, or permit to be discharged into the sanitary sewer system or any part thereof, any wastewater with objectionable color not removed in the treatment process such as, but not limited to, dye wastes and vegetable tanning solutions.

Therefore, further review of turbidity for evaluation as an industrial local limit is not warranted at this time. In addition, turbidity would not reasonably be expected to result in interference, biosolids contamination, collection system problems, or increased worker jeopardy. 3.2.4 Local Limits POCs Local limits are developed to reflect specific needs and capabilities at individual POTWs and are designed to protect the ambient receiving waters. Regulations in 40 CFR 403.8(f)(4) state that POTW Pretreatment Programs must develop local limits or demonstrate that they are unnecessary; 40 CFR 403.5(c) states that local limits are needed when pollutants are received that could result in pass through or interference at the POTW. Essentially, local limits translate the general prohibited discharge standards of 40 CFR 403.5 to site-specific needs.

Toxic substances with local limits already regulated by the sewer use ordinance should be evaluated to determine if a constituent should remain a POC. The pollutants with industrial local limits not already assessed above include: antimony, beryllium, manganese, phenol and its derivatives (total phenol). 3.2.4.1 Phenols and Derivatives There are criteria for individual phenol compounds, but not one for the sum. Phenol had effluent sample results above the detection limit, while all other results for phenolic compounds monitored were below the detection limit. Therefore, this evaluation used phenol water quality criteria to derive the MAHL. The recommendation is that future local limits analyses consider removing this limit from the local limits after the Facility undergoes the significant modifications that will occur after implementation of the Facility’s Master Plan. Additionally, samples collected for compliance with this limit at the Industrial Users are analyzed using EPA Method 420.1, which reports the results as Total Recoverable Phenolics. The name for this POC in the Local Limits will be updated to Phenols, Total, to better represent the test results.

3.2.4.2 Other Organics Prior to the 2006 Local Limits Evaluation, there was a local limit for total toxic organics. The evaluation included screening 2013 to 2017 data to determine if any of these pollutants would pose a reasonable potential. This screening did not identify any new POC with reasonable potential. Appendix C summarizes the screening for organics data.

3.3 Collecting Facility Influent, Effluent, and Biosolids Data Evaluating the performance of current local limits and developing MAHLs for POCs requires various types of pollutant information. Most of the concentration data required was readily available from data collected by the Facility for regulatory compliance. The data assembled for this evaluation included:

• Facility Influent, effluent, and biosolids concentration data for 2013 to 2017, • Facility influent, effluent and South Bay Water Recycling flow data for 2013- 2017, and • Biosolids characteristics and generation rate.

The Guidance Manual recommends using a minimum of 3 years of data. This evaluation used five years of data from January 2013 through December 2017. Data from 2013 onwards were included to incorporate data from the last permit reasonable pollutant analysis. The expanded data range provides a conservative bias to the MAHL process.

3.3.1 Non-detectable Data Laboratory analytical methods may provide different minimum detection limits (MDLs) and minimum reporting levels (MLs). For this report, the MDL is the lowest concentration level the laboratory can detect as defined in 40 CFR Part 136, whereas MLs represents the lowest calibration standard used for a specific analytical procedure. The Facility’s 2014 NPDES permit includes criteria for the MLs for pollutant effluent limits, and includes other requirements related to MLs. For this evaluation, EPA-approved test methods were initially selected to provide a numerical value above the minimum detection level. However, there is a point for each contaminant at which the concentration becomes too low to be accurately detected by the most sensitive standard methods presently available.

Although numerical values above the minimum detection level and below the minimum reporting level can be determined, these values are not accurate enough to be considered quantifiable for comparison with regulatory limits. Therefore, these values are considered “detected but not quantified (DNQ).”

For this local limits evaluation, the DNQ values were used for developing the pollutant removal rates and evaluating the influent and effluent loading, where available. Any results below the minimum detection limits were replaced with one half minimum detection limits. 3.3.2 Influent Data Outliers The Guidance Manual states that influent spikes from spills should not be used as a basis for decreasing local limits. In addition, with such a large number of analytical results, unrepresentative “outlier” values may occur, as a result of sampling or analysis process variance. Therefore, consistent with recommendations in the Guidance Manual, the data sets for metals and conventional pollutants were evaluated to identify outliers for potential exclusion from the ensuing MAHL calculations. Since organic contaminants had much smaller data sets than that for metals and conventional parameters, organics were not evaluated for outliers.

3.3.2.1 Outlier Determination The Guidance Manual includes two tests to determine outliers. 1. If the data follow a normal distribution, data points more than two standard deviations from

the mean are considered outliers. a. Calculate the mean of each data set b. Calculate the standard deviation of each data set c. Calculate the threshold for outliers by adding two times the standard deviation to the mean

for each data set d. Designate any value above this concentration threshold an outlier 2. If the data do not follow a normal distribution, data points more than one and a half times the

difference between the third and first quartile values above the third quartile value are considered outliers.

a. Determine the first and third quartile values for each data set b. Calculate the difference between the first and third quartile values for each data set c. Calculate the threshold for outliers by adding one and one-half times the difference between

the first and third quartile values to the third quartile value for each data set d. Designate any value above this concentration threshold an outlier. With a large set of data and using the third decile method for calculating the removal rates, the exclusion of a few data points makes very little difference in the calculated removal rates. Therefore, none of the data was excluded from the removal rate calculations. Most of the average MAHL values are based on other criteria than overall Facility pollutant removal. The comparison of MAHL values to average headworks loadings are well under the thresholds for further evaluation described in the Guidance Manual and the conclusions are not affected by the inclusion of any potential outliers. However, the use of outliers for daily maximum limit-based MAHLs is more problematic. For example, a single influent copper concentration was four times the next highest value. This outlier was removed from the comparison of the Facility loading to the MAHL for maximum daily copper. Although this influent copper value if used would be above the MAHL daily maximum value, the corresponding effluent copper concentration was not elevated, indicating the effluent concentrations may not be primarily influenced by the influent values. Similarly, a single influent outlier value was removed from the data set for lead. The data sets for other sampling results, especially biosolids, are small and all the available sample results are used in the AHL calculations 3.3.3 2018 POC for MAHL Analysis “Table 3: Maximum and Average Influent and Effluent Selected POC Concentrations from 2013 through 2017” lists the POCs that have been selected for further local limits analysis, along with concentration and loading data for the period January 2013 –December 2017. The sources of each POC is listed in “Table 4: Sources of POC Criteria for Calculation of Each AHL”. Sources include the NTR, the CTR with values from Reasonable Potential Analysis from the NPDES Permit Orders (CTR-RPA to account for hardness), NPDES Permit Orders daily maximum and monthly averages (Permit MA and Permit DM, respectively), Guideline Manual Appendix Tables Minimum and Average Values for inhibition criteria (Table Min and Table Avg, respectively), and TTLC criteria. The concentration and loading values will be used for comparison with the MAHL developed in the next section.

3.4 Calculating Removal Rates Removal rate is the amount of a pollutant removed from the wastewater during the wastewater treatment process expressed as a percentage of the influent quantity. Removal rates for each POC are fundamental inputs to the MAHL calculations. The Guidance Manual recommends using one of three methods to calculate a removal rate for the entire data set, depending on the amount of data available. Removal rates can be calculated for the entire treatment process or for part of the treatment process. This report utilizes two types of removal rates based on the specific AHL calculation performed: Primary effluent removal rates and final effluent removal rates. 3.4.1 Primary Effluent Removal Rates The Guidance Manual recommends using primary effluent removal rates for activated sludge and secondary removal rates for nitrification inhibition calculations based on a traditional activated sludge/nitrification process where primary effluent enters the activated sludge followed by the nitrification treatment system, However, since the Facility‘s BNR treatment process combines the activated sludge and nitrification treatment into one process, primary effluent enters the BNR process and the “activated sludge” and “nitrification” quads at the same time . Therefore, the “primary removal rate” would be used instead of the “secondary removal rate” in the nitrification inhibition AHL.

The primary removal rate is the percentage of influent potential POC loading that is removed from the wastewater through the Facility’s primary processes. These processes included the bar screen, grit removal, and primary sedimentation systems. Most of the POCs do not have site-specific removal rate data and would require using either literature values from the Guideline Manual Appendix “R” or an assumed “worst-case scenario” of zero percent removal. Inhibition-based AHLs were not calculated based on screening criteria as described in Section 3.5.2.1 and the primary effluent removal rates were not used. 3.4.2 Final Effluent Removal Rates There are three methods for calculating effluent removal rates, third decile removal efficiency (TDRE) method, the average daily removal efficiency (ADRE) method, and the mean removal efficiency (MRE) method. The following describes the removal methods and evaluates the applicability of the removal rates selections. 3.4.2.1 TDRE Removal Rates The Guidance Manual describes the TDRE method for calculating effluent removal rates used in water quality AHL equations as one that provides a more comprehensive view of the removal rates, because it takes into consideration the frequency distribution of the data. It also allows for explicit incorporation of daily removal efficiency and is generally more conservative with respect to pass- through AHL calculations.

The effluent removal rate is the percentage of influent POC loading that is removed from the wastewater through all of the Facility processes. The effluent concentration value used to calculate the final effluent removal efficiency is the POC concentration value taken at the NPDES final effluent sample point

3-10

The TDRE is calculated as follows:

EREi Where:

= (Ii - Ei)

Ii

EREi = Effluent removal efficiency for each daily influent and effluent pair (%). Ii = The ith individual influent concentration sample result (mg/l) Ei = The ith individual effluent concentration sample result (mg/l) N = The total number of paired influent and effluent sample results

After calculating removal efficiencies for each daily influent and effluent pair, the removal efficiency values are ranked from lowest to highest. Next, the TDRE value is determined based upon the number of samples (N) multiplied by 30%. The TDRE removal rate is the EREi at this 30% rank, as determined by using linear regression based on the sample rank and corresponding removal efficiencies. This calculated ranked value is the removal rate. Calculations and illustration of the ranking method for all the TDRE Removal Rates for each POC are presented in Appendix B.

3.4.2.2 Average Daily Efficiency Method Similar to the TDRE method, the average daily effluent removal rate requires calculation of removal efficiencies based on paired influent and effluent data. However, this method calculates the removal rate by averaging the resulting removal efficiencies.

Calculations of the ranking method for all the ADRE Removal Rates for each POC are presented in Appendix B.

3.4.2.3 Mean Efficiency Effluent Removal Rate Some POCs did not have enough paired data to calculate a statistically robust final effluent removal rate based on individual removal efficiencies. This mean efficiency effluent removal rate method requires first averaging all influent sample results and all the effluent sample results before calculating the removal rate of these averaged values.

Calculations of the ranking method for all the MRE Removal Rates for each POC are presented in Appendix B.

3.4.2.4 Comparison of Final Effluent Removal Rate Calculation Methodologies “Table 5: Final Effluent Removal Efficiency Rates Using Various Methods” summarizes the 2013 to 2017 calculated effluent removal rates using the various methods. The removal rates for each of the methods are within a few percentage points of the others, with the TDRE removal rate having the lowest value. Cyanide has a negative removal rate due to the production of a small amount of cyanide from the Facility’s chloramination disinfection process. The variability in the data used for the cyanide TDRE calculations indicates that there may be little correlation between the generation of cyanide from chloramination disinfection and the incoming cyanide.

The activated sludge inhibition and nitrification inhibition criteria used primary effluent rates and the anaerobic digestion criteria used MRE removal rates. “Table 6: Selected Removal Rates for POCs per Application” summarizes the various removal rates used for each POC. The evaluation used the Guidance Manual literature final removal rate for cyanide for anaerobic digestion inhibition criteria, since the Facility’s chloramination process produces cyanide, and the disinfection process generates no sludge.

3.5 Calculating AHL The AHL is calculated from the POC concentration criteria with the corresponding removal rates and safety factors. An AHL is the estimated maximum loading of a pollutant that can be received at a POTW's headworks that should not cause a POTW to violate a particular treatment Facility limit or environmental criterion. An AHL is calculated for each applicable criterion: pass through, biosolids contamination, air quality standards, and the various forms of interference (biological treatment inhibition, sludge digestion inhibition). The AHLs for each POC are calculated based on the various suitable environmental criteria, Facility flow rates, and Facility removal efficiency. After calculating a series of AHLs for each POC, the lowest AHL is chosen as the MAHL.

3.5.1 WQC AHL WQC AHLs were calculated for each POC. WQC were obtained from either the Facility’s NPDES permit value, the CTR, or NTR. Beryllium and molybdenum have no WQC for discharge to the South San Francisco Bay, at this time.

WQAHL = 8.34 × Cwqc × Qavg (1 − FERR)

Where: WQAHL = AHL based on WQC (ppd) for each POC 8.34 = Unit conversion factor Cwqc = Monthly average POC WQC (mg/l) or daily maximum, as applicable Qavg = Influent average annual flow (mgd) FERR = Final effluent removal rate for each POC

For POC with both daily maximum and monthly average limits contained in the NPDES Permit Order, the evaluation used the Daily Maximum WQC to compute a Daily Maximum AHL and the monthly average WQC to compute a monthly average AHL. These POC include Copper, Cyanide, Nickel, Ammonia, BOD, and TSS. All other WQC based AHL are daily maximum values only. These criteria and calculated Daily Maximum AHL are listed in “Table 10: Daily Maximum MAHL for Toxic Pollutants for comparison with 80% Screening. These Daily Maximum AHLs, after being multiplied by 80% are used in this evaluation as local limit recalculation threshold limits for comparing maximum effluent data for these POCs, as is consistent with the Guidance Manual. The monthly average MAHLs, after being multiplied by 60% are used in the evaluation as local limit threshold limits also. 3.5.2 Facility Inhibition Pollutant levels in wastewater or biosolids may cause operational problems for biological treatment processes involving secondary and tertiary treatment. Disruption of a POTW’s biological processes is referred to as inhibition and can interfere with a POTW’s ability to remove BOD and other pollutants. A POTW should assess any past or present operational problems related to inhibition through the local limits review process. 3.5.2.1 Facility Inhibition Criteria The Guidance Manual states POTWs may not need to calculate AHLs to protect against inhibition if current loadings are acceptable to the treatment works’s biological processes. However, a POTW may still choose to calculate AHLs based on biological process inhibition criteria to prevent future loadings that may cause inhibition. The Guidance Manual provides literature-based inhibition criteria for activated sludge, nitrification, and anaerobic digestion. However, the Facility’s treatment processes combine activated sludge and nitrification into one step in the BNR process. Since the combined system contains some of the same biomass, such as nitrifying bacteria, as traditional activated sludge treatment followed by nitrification processes—this evaluation used the lowest applicable Guidance Manual criteria given for either the activated sludge or nitrification process as the initial basis for selecting inhibition criteria. Since the Facility processes also include anaerobic digestion, these inhibition values were also included in the analysis. Inhibition was not observed in the operations of the Facility during the evaluation period. Site specific inhibition values are not available for the Facility and the applicability of the literature values is unknown. Therefore, a screening was performed to compare the maximum influent concentrations of the POC to the literature inhibition criteria to determine if further evaluation might be necessary. The maximum influent measured during the five-year evaluation period is well below the inhibition criteria for all POCs except copper and zinc (See Table 7: Inhibition Screening for Further Evaluation). Using the influent value disregards any removal occurring during the treatment process prior to the biological processes. Previous research indicates a

3-14

removal rate for copper of 43% and literature values indicate a removal rate for zinc of 27% during primary treatment. A similar removal at the Facility would reduce the concentration of copper and zinc below any literature inhibition values. Inhibition does not appear to be a likely basis for the establishment of any local limits and inhibition criteria will not be evaluated further as part of the MAHL calculations.

Phenols 1 - - - 3.5.3 Biosolids-Based AHL In February 1993, EPA issued the Part 503 Biosolids regulations governing the use or disposal of sewage sludge. Pollutant levels were established for three disposal alternatives: land application to condition the soil or fertilize crops grown in the soil, surface disposal for final disposal, and incineration. The pollutant levels, however, are different for each alternative. In addition to the Federal standards, California may apply state hazardous criteria depending upon the ultimate biosolids application. Regardless of how a POTW disposes of biosolids, POTWs may wish to consider using land application “clean sludge” values from 40 CFR 503.13 in their calculation of AHL. Use of these criteria can improve a POTW’s beneficial use options for disposal of biosolids. The further achievement of these standards is consistent with the objectives of the National Pretreatment Program, which are listed at 40 CFR 403.2. The Facility seeks to maximize the opportunities for beneficial use to the maximum extent practicable, which may include application to agricultural land, forest, public contact site, reclamation site, lawn or garden, and landfill. The Facility currently disposes of its biosolids as cover at a nearby landfill. According the Guidance Manual, the biosolids criteria to be used for these applications are:

• “Clean Sludge” Pollutant Concentration Limits contained in Table 1 (Ceiling Concentrations) in 40 CFR 503.13 (1995),

3.0 MAHL ANALSISI PROCESS FOR EVALUATING LOCAL LIMITS

2018 San José-Santa Clara Regional Wastewater Facility Industrial Wastewater Local Limits Update

3-15

• “Clean Sludge” Pollutant Concentration Limits contained in Table 3 (Monthly Average Pollutant Concentrations) in 40 CFR 503.13 (1995),

• Surface disposal limits for 0 to 25 feet from the boundary of an active surface disposal site contained in Table 1 and 2 in 40 CFR 503.23 (1995),

• California Hazardous Waste Total Threshold Limit Concentration, contained in tables in Title 22, Division 4.5, Chapter 11, Article 3, §66261.24

All of the biosolids criteria were converted to dry weight for use in AHL calculations and to compare with dry weight sludge samples. The equation below was used to calculate the biosolids-based AHLs:

BBAHL = 8.34 × CH × QH × CBSQC CBSM

Where:

• BBAHL = Biosolids Based AHL based on biosolids criteria (ppd) for each POC CH = Facility influent concentration for each POC in mg/l QH = Facility influent flow in million gallons per day 8.34 = Conversion factor CBSQC = Biosolids Quality Criteria Concentration for each POC in mg/kg CBSM = Biosolids Measured Concentration for each POC in mg/kg 3.5.4 OSHA Health and Safety AHL None of the POCs evaluated have OSHA Health and Safety Criteria.

3.6 Selecting MAHLs Protecting water quality, biosolids quality, and air quality requires selection of the lowest AHL value for each potential POC for use as the maximum allowable headworks loading. “Table 8: Summary of the POC AHLs” lists the AHLs calculated using water quality and biosolids criteria.

The Guidance Manual recommends comparing the calculated MAHLs to the influent loadings to determine if the existing local limits remain protective. The MAHLs were calculated using average values, such as the removal rates for five years of influent and effluent concentrations and biosolids samples results. Some of the POCs also have Daily Maximum limits. An MAHL for each POC based on maximum limits is shown in “Table 9: Daily Maximum MAHL for Toxic Pollutants for comparison with 80% Screening.”

3.7 Identifying POCs Requiring New or Revised Local Limits The Guidance Manual states that once a POTW has calculated MAHLs for all of its POCs, it can determine for which pollutants it will require local limits. In making this pollutant-by-pollutant evaluation, the POTW will also want to consider historical issues and the degree to which current influent loadings approach calculated MAHLs. For example, the concentration of some pollutants in the POTW influent may be far below the calculated MAHLs. These pollutants are unlikely to cause problems for the POTW, so the treatment works may conclude that local limits for them are unnecessary. EPA recommends that the POTW document such decisions and discuss them with its Approval Authority, as needed.

Identifying those POCs requiring new or revised local limits is performed by comparing the Facility’s influent loading for each POC to its corresponding MAHL. If the influent loading comparison to the MAHL does not meet the screening criteria, then the local limit may need to be revised. 3.7.1 Comparing Threshold Limits to POCs The Guidance Manual recommends that local limits are needed when the following thresholds are satisfied:

• Average influent loading of a toxic pollutant exceeds 60 percent of the MAHL, or • Maximum daily influent loading of a toxic pollutant exceeds 80 percent of the MAHL any time in

the 12-month period preceding the analysis, or • Monthly average influent loading exceeds 80 percent of average design capacity for BOD, TSS,

and ammonia during any one month in the 12-month period preceding the analysis.

The Guidance Manual offers the following guidance on this comparison between MAHLs and headworks loading where local limits have not been established:

• If the current POC headworks loading exceeds the MAHL, EPA recommends that the POTW establish a local limit for the pollutant to investigate the cause of elevated loading, increase its

industrial users monitoring, identify any non-complying industries, and consider undertaking pollution prevention efforts.

• If the current POC headworks loading exceeds the threshold values for the first time (i.e., the loading was below the threshold value during the year before), EPA recommends that the POTW increase monitoring for the POC or establish a local limit for it.

• If the current POC headworks loading exceeds the threshold value for the second time, EPA recommends establishing a local limit and increasing POC monitoring.

• If the current headworks loading is below the threshold, EPA recommends that the POTW review the pollutant’s loading as part of its preparation of next year’s annual report.

Similarly, EPA recommends the following guidance for POCs with established local limits:

• If the current POC headworks loading exceeds the MAHL, EPA recommends revising the local limits (unless an investigation reveals that the elevated loading is due to an unusual, one-time event), investigating the cause of the high loading, identifying any industries in non-compliance, increasing monitoring of industrial users, and considering adopting pollution prevention efforts.

• If the current POC headworks loading has increased significantly from the previous year (e.g., from 55 percent to 75 percent of the MAHL), EPA recommends that the POTW investigate the cause of the increased loading, increase the monitoring for the POC, or revise the local limit.

• If the current headworks loading is below the threshold, EPA recommends that the POTW review the pollutant’s loading as part of its preparation of next year’s annual report.”

“Table 10: Daily Maximum MAHL Compared to Maximum Influent Loading” and “Table 11: Comparison of MAHLs to Local Limit Threshold Screening Results” present a comparison of MAHLs, threshold screening values, and influent loading to determine whether there is a need to revise or implement new local limits for each POC. If the respective influent loading was above the corresponding screening value, then a new or revised local limit may be required. If the respective influent loading was below the corresponding screening value, then the existing local limit is considered protective.

“Table 12: MAHL Threshold Screening Results” summarizes the results of the threshold-screening analysis for all of the POCs. None of these screening values was exceeded, indicating that new or lowered local limits are not warranted at this time. Moreover, data for many of the POCs indicate there is ample headworks loading capacity for these contaminants, and their corresponding industrial local limits may be decidedly conservative.

3.7.2 Screening Analysis for “National” POCs The conventional contaminants ammonia, biochemical oxygen demand, and total suspended solids warrant further technical analysis to determine their appropriateness as POCs. The following presents a discussion of these conventional pollutants as POCs.

3.7.1.1 Ammonia The NPDES permit limits for ammonia are 8 mg/l as a daily maximum and 3 mg/l as a monthly average. Ammonia has not been considered a POC in the past because the Facility was designed for high-strength seasonal cannery wastes, the canneries are now closed, and all effluent data were found to be well below the applicable NPDES permit limits between 2013 and 2017. Facility effluent ammonia data for the period 2013 – 2017 are characterized by a mean of 0.6 mg/l and a maximum of 3.2 mg/l. In addition, the City has a narrative “interfering substances” sewer use ordinance limitation that has proven protective of the collection system and treatment Facility with respect to ammonia. Section 15.14.585 Part B of the San José Municipal Code reads:

No person shall discharge, cause, allow, or permit to be discharged into the sanitary sewer system or any part thereof, any toxic or poisonous substances or any other pollutant, including biochemical oxygen demand, in sufficient quantity to injure or cause an interference with the sewage treatment process, or in sufficient quantity to constitute a hazard to humans or animals, or in sufficient quantity to create a hazard for humans, or aquatic life in any waters receiving effluent from the sanitary sewer system, or which may create a hazard in the use or disposal of sewage sludge.

The City encourages minimization of the discharge of ammonia on its largest industrial dischargers, those discharging greater than 25,000 gallons of wastewater daily, through a “revenue program” whereby the industrial facility is charged according to the ammonia loading discharged to the collection system.

3-22

Based on these factors, the City finds that further review of ammonia for evaluation as an industrial local limit is not warranted at this time. In addition, ammonia would not reasonably be expected, with pretreatment regulations and wastewater treatment currently in effect, to result in pass through, interference, biosolids contamination, collection system problems, or increased worker jeopardy. However, this evaluation does include the calculation of an MAHL for Ammonia to conform to the Guidance Manual standard.

3.7.1.2 Biochemical Oxygen Demand (BOD) The NPDES permit limits for BOD are 20 mg/l as a daily maximum and 10 mg/l as a monthly average. BOD has not been considered a POC in the past because the Facility was designed for high-strength seasonal cannery wastes, the canneries are now closed, and all effluent data were found to be well below the applicable NPDES permit limits between 2013 and 2017. Facility effluent BOD data for the period 2013 – 2017 are characterized by a mean of 2.7 mg/l and a maximum of 7 mg/l. The narrative “interfering substances” sewer use ordinance referenced above has proven protective of the collection system and treatment Facility with respect to BOD.

The City encourages minimization of the discharge of BOD on its largest industrial dischargers, those discharging greater than 25,000 gallons of wastewater daily, through a “revenue program” whereby the industrial facility is charged according to the BOD loading discharged to the collection system.

Therefore, further review of BOD for evaluation as an industrial local limit is not warranted at this time. In addition, BOD would not reasonably be expected, with pretreatment regulations currently in effect, to result in pass through, interference, biosolids contamination, collection system problems, or increased worker jeopardy. However, this evaluation does include the calculation of an MAHL for BOD to conform to the Guidance Manual standard.

3.7.1.3 Total Suspended Solids (TSS) The NPDES permit limits for TSS are 20 mg/l as a daily maximum and 10 mg/l as a monthly average. TSS has also not been considered a POC in the past because the Facility was designed for high-strength seasonal cannery wastes, the canneries are now closed, and all effluent data were found to be well below the applicable NPDES permit limits between 2013 and 2017. Facility effluent TSS data for the period 2013 – 2017 are characterized by a mean of 1.5 mg/l of and a maximum of 1.6 mg/l. In addition, the City has a narrative “suspended solids/dissolved matter” sewer use ordinance limitation that has proven protective of the collection system and treatment Facility with respect to TSS. Section 15.14.595 of the San José Municipal Code reads:

No person shall discharge, cause, allow or permit to be discharged into the sanitary sewer system or any part thereof, any liquid containing suspended solids or dissolved matter of such character and quantity that unusual attention or expense is required to handle, process or treat such matter at the Facility.

The City encourages minimization of the discharge of TSS on its largest industrial dischargers, those discharging greater than 25,000 gallons of wastewater daily, through a “revenue program’ whereby the industrial facility is charged according to the TSS loading discharged to the collection system. In addition, TSS would not reasonably be expected, with pretreatment regulations currently in effect, to result in pass through, interference, biosolids contamination, collection system problems, or increased worker jeopardy. Therefore, further review of TSS for evaluation as an industrial local limit is not warranted at this time. However, this evaluation does include the calculation of an MAHL for TSS to conform to the Guidance Manual standard.

4.0 Additional Protections for Collection System The Guidance Manual states that POTWs may need to develop local limits to address concerns about their collection systems and meet the requirements found at 40 CFR 403.5(b), which include protecting the health and safety of workers at the POTW. The guidance specifically describes the following collection system concerns:

• Fires and explosions, • Corrosion, • Flow obstructions, • Temperature, and • Toxic gases, vapors and fumes.

As part of the local limits evaluation process, the City also conducted a review of the sewer ordinance to ensure that these protections were already in place. 4.1 Fires and Explosions The General Pretreatment Regulations prohibit discharge of pollutants that will create a fire or an explosion in the collection system or the treatment facility. To protect from fires and explosions, the City’s sewer use ordinances contain a prohibition on substances having a closed-cup flashpoint of less than 140oF or 60oC. 4.2 Corrosion To protect the sewer system and treatment facility from corrosive discharges, the General Pretreatment Regulations prohibit discharges that will cause corrosive damage to the collection system and POTWs. The City’s sewer use ordinance prohibits discharges with a pH less than 6 or greater than or equal to 12.5 or having other corrosive properties capable of causing damage or hazard to the sanitary sewer system or any personnel operating or maintaining the sanitary sewer systems. 4.3 Flow Obstructions The discharge of solid or viscous pollutants in amounts that will obstruct the flows to the treatment Facility or interfere with the proper operation or maintenance of the sanitary sewer system is prohibited by the General Pretreatment Regulations. The greatest threat of obstruction at POTWs comes from polar fats, oils and greases of animal and vegetable origin. The City has an Oil & Grease local limit of 150 mg/l and sewer use ordinance language prohibiting the discharge of obstructing or injurious substances. City staff reviews food facility plans and specifications to require the appropriate sizing of grease removal devices. In addition, the City has implemented an inspection program for its 3000+ restaurants and food facilities. This inspection program verifies the installation and maintenance of grease removal devices, and the following of other BMPs regarding grease removal. 4.4 Temperature The General Pretreatment Regulations prohibit discharges that will inhibit the biological activity in the POTW and result in interference. In no case can discharges increase the temperature of the headworks above 104oF unless the Approval Authority, upon request of the POTW, approves alternative limits. The City’s sewer use ordinance already prohibits the discharge of any liquid,’ solid, vapor, or gas discharges with a temperature of 150 oF or more or that causes the temperature of the Facility to exceed 104oF.

4.5 Toxic Gases and Fumes The General Pretreatment Regulations prohibit the discharge of pollutants that lead to the accumulation of toxic gases, vapors, or fumes in the POTW in sufficient quantity to cause acute worker health and safety problems. The City’s sewer use ordinance already includes a prohibition against the discharge of substances which results in the presence of toxic gases, vapors or fumes within the sanitary sewer system.

6.0 Approval Process for Local Limits Review

Section 101(e) of the CWA establishes public participation as one of the goals in the development, revision, and enforcement of any regulation, standard, effluent limitation, plan, or program established by EPA or any State. The General Pretreatment Regulations encourage public participation by requiring public notices or hearings for program approval, removal credits, program modifications, local limits development and modifications, and IUs in significant non-compliance.

Before there is a significant change in the operation of a POTW pretreatment program, a program modification must be initiated. For a substantial program modification, such as the development of new or less stringent local limits, the POTW is required to notify the Approval Authority of the desire to modify its program and the basis for the change. Approval Authorities (or POTWs) also are required to issue public notice of the request for a modification but are not required to issue public notice of the decision if no comments are received and the request is approved without changes. These changes become effective upon approval by the Approval Authority.

Since no modifications of the local limits or pretreatment program are recommended or proposed as a result of this review, no notification and approval process is required. The final report will be submitted to the Water Board and EPA as part of the annual pretreatment report in February 2019. If the City does not receive any comments from the Water Board or EPA within 90 days from submittal, the final report will be considered complete.

Pretreatment Program Expenses For Fiscal Year 2017-2018

The total number of staff devoted to the pretreatment program including staff in Source Control, the Laboratory, and Engineering is 37.45 full-time employees. Personal service expenses, including fringe benefits, and non-personal expenses were $4.95 million. The table entitled, “Pretreatment Program-Actual Expenditures,” is a breakdown of these expenses. The table entitled “Pretreatment Program Personnel Report” is a breakdown of the FTE positions for the program.

Non-personnel expenses include supplies, training, printing reports, dues, and subscriptions. The table includes line items for outreach materials and contract work.

The Laboratory personnel distribution was based on sample work load, type of analysis (wet chemistry or using advanced instruments), level of training or experience of the staff, and requested turn-around times.

The source of the funding is the Treatment Plant Operating Fund (Fund 513), comprised of funding from the tributary agencies. Revenue for this fund is generated through the collection of sewer use fees on the customer’s property tax bill in San José and payments from the other tributary agencies.

EPA's sewage sludge regulations require certain publicly owned treatment works (POTWs) and Class I sewage sludge management facilities to submit to a Sewage Sludge (Biosolids) Annual Report (see 40 CFR 503.18(https://www.ecfr.gov/cgi-bin/text-idx?node=pt40.32.503&rgn=div5#se40.32.503_118), 503.28 (https://www.ecfr.gov/cgi-bin/text-idx?node=pt40.32.503&rgn=div5#se40.32.503_128), 503.48 (https://www.ecfr.gov/cgi-bin/text-idx?node=pt40.32.503&rgn=div5#se40.32.503_148)). Facilities that must submit a Sewage Sludge (Biosolids) Annual Report include POTWs with a design f low rate equal to or greater than one million gallons perday, POTWs that serve 10,000 people or more, Class I Sludge Management Facilities (as def ined by 40 CFR 503.9 (https://www.ecfr.gov/cgi-bin/text-idx?node=pt40.32.503&rgn=div5#se40.32.503_19)), and facilitiesotherwise required to f ile this report (e.g., permit condition, enforcement action, state law). This is the electronic form for Sewage Sludge (Biosolids) Annual Report f ilers to use if they are located in one of the states,tribes, or territories (https://www.epa.gov/npdes/npdes-state-program-information) where EPA administers the Federal biosolids program.

For the purposes of this form, the term 'sewage sludge (https://www.ecfr.gov/cgi-bin/text-idx?node=pt40.32.503&rgn=div5#se40.32.503_19)' also refers to the material that is commonly referred to as 'biosolids'. EPAdoes not have a regulatory def inition for biosolids but this material is commonly referred to as sewage sludge that is placed on, or applied to the land to use the benef icial properties of the material as a soil amendment,conditioner, or fertilizer. EPA's use of the term 'biosolids' in this form is to conf irm that information about benef icially used sewage sludge (a.k.a. biosolids) should be reported on this form.

Please note that EPA may contact you after you submit this report for more information regarding your sewage sludge management program.

and analytical batch 440-492732 failed below acceptance limits. Per the EPA method, this analyte is subject to oxidative loss during sample preparation.

Method(s) 8270C: The following sample was diluted due to the abundance of non-target analytes: LE26854 (440-217336-22). Elevated reporting limits (RLs) are provided.

Method(s) 8270C: The matrix spike / matrix spike duplicate / sample duplicate (MS/MSD/DUP) precision for preparation batch 440-492340 and analytical batch 440-492732 was outside control limits. Sample matrix interference and/or non-homogeneity are suspected.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

GC Semi VOA Method(s) 8015B: The 8015-DRO method blank for preparation batch 440-492650 and analytical batch 440-493099 contained C18-C40 above the method detection limit. This target analyte concentration was less than the reporting limit (RL); therefore, re-extraction and/or

re-analysis of samples was not performed.

Method(s) 8015B: The 8015-DRO method blank for preparation batch 440-492650 and analytical batch 440-493099 contained C10-C22 and C10-C28 above the reporting limit (RL). Associated sample(s) were not re-extracted and/or re-analyzed because all associated

sample results in this extraction batch were greater than 10X the value found in the method blank. LE26860 (440-217336-28) and (MB 440-492650/1-A)

Method(s) 8081A: The matrix spike recoveries for preparation batch 440-492633 and analytical batch 440-492728 were outside control

limits. Sample matrix interference is suspected because the associated laboratory control sample (LCS) recovery was within acceptance

limits.

Method(s) 8081A: The matrix spike / matrix spike duplicate (MS/MSD) precision for preparation batch 440-492633 and analytical batch

440-492728 was outside control limits. Sample matrix interference and sample non-homogeneity are suspected.

Method(s) 8081A: The following samples required a copper clean-up to reduce matrix interferences caused by sulfur: LE26856 (440-217336-24), (LCS 440-492633/2-A), (MB 440-492633/1-A), (440-217336-A-24-A MS) and (440-217336-A-24-B MSD).

Method(s) 8082: Surrogate recovery for the following samples was outside control limits: LE26855 (440-217336-23). Evidence of matrix interference is present; therefore, re-extraction and/or re-analysis was not performed.

Method(s) 8082: : (440-217643-B-1-C). The following sample contained more than one Aroclor with insufficient separation. Results

biased high due to shared peaks: (440-217643-B-1-C).

Other Subjects in 2018

Surveillance Activities

In 2018, the City performed surveillance monitoring at four permitted Industrial Users

(IUs): Hammon Plating, Applied Anodize, Inc., TTM Technologies, Santa Clara Plating

Company, and Du All Anodizing Company. This monitoring was conducted in accordance

with the City’s 2018 Surveillance Monitoring Annual Work Plan. A total of 51 composite

samples were collected. Anomalies in excess of local discharge limits were identified in

samples collected at Hammon Plating and TTM Technologies. Enforcement will be issued

in 2019 pending an investigation. Surveillance monitoring of additional IUs will continue

in 2019.

Discharger Identification Program

The Industrial User Identification and Inventory Program, also known as Industrial

Surveys, includes several methods for identifying potential IUs. Methods include

reviewing new business licenses, conducting internet searches, following-up on

information collected during routine inspections and plan checks for new industries, and

investigating referrals from other agencies. The program also includes more frequent

inspections of de-permitted or closed IUs, improved documentation of IU assessment and

inspection activities, additional identification and characterization training for inspection

staff, and improved interaction with member agencies and other regulatory agencies.

Additionally, the City has continued to update guidance documents and SOPs for the

Industrial User Identification and Inventory Program.

In 2018, 37 potential IUs were identified and investigated. Of the 37 IUs investigated, two

were permitted, and 35 did not require a permit. Of the 35 that did not require a permit, 32

were notified in person and three were issued “No Permit Required” letters. Additionally,

one was placed on a re-inspection schedule.

will be performed for the remaining dental facility permit applications in 2019.

Partnerships

Pretreatment staff continue to participate in regional collaborative efforts with other public

agencies in 2018. These collaborative efforts ultimately resulted in improved protection for

the environment. Brief descriptions are provided below:

• The City’s Pretreatment Program management staff attend and actively participate

in quarterly Bay Area Clean Water Agencies (BACWA) Pretreatment regional

agency meetings. Agency members participate in development of regional Best

Management Practices (BMPs), discussions on various pretreatment program

compliance topics, and adoption of updated EPA rules and regulations.

Industrial User Academy

Industrial Users sent participants to the City’s annual Industrial User Academy on April

18, 2018. The Industrial User Academy is an interactive workshop that assists participants

in understanding their Discharge Permit requirements and methods for maintaining

compliance. Often, IUs send new employees or those responsible for the IU’s

Environmental Health and Safety issues to the training. At the Academy, City inspectors

presented hands-on modules that included review of user’s current permit in small groups.

Inspectors reviewed Self-Monitoring Reports (SMRs) and ways to avoid common errors.

Inspectors described their field methodology for sampling, Chain of Custody and testing

IU samples at the City’s lab. In 2018, a total of 34 participants attended from different

permitted facilities.

Other Presentations

On June 20, 2018, Jaime Gutierrez, Assistant Environmental Inspector, and Jarred

Klosinski, Environmental Inspector, performed a water quality testing demonstration for

Elementary School teachers as part of a Wastewater Treatment STEM training hosted by

the City.

Septic Hauler Monitoring Program

The City’s Septic Hauler Program accepts only domestic wastes originating from sanitary

uses, specifically septic tanks and portable toilets from homes and businesses. The

Pretreatment Program continues to issue three-year term permits to septic haulers. In 2018

a total of 15 haulers were permitted within the City’s jurisdiction for discharge at the

Wastewater Facility. To protect the Wastewater Facility, septic samples are collected from

every load of septage delivered to the Wastewater Facility. In 2018, the City collected

3,428 samples from Septic Haulers of which 1,194 or 35 percent were randomly selected,

analyzed, and screened for abnormal results. Abnormalities included samples with

unusually high metal concentrations and samples collected outside the tributary area. The

City issued two Notices of Violation, two Administrative Citations, and one Warning

Notice to Septic Haulers for violations of the City of San José Municipal Code.

Temporary Discharge Permit Program

Temporary Discharge Permits are issued primarily for the discharge of contaminated

groundwater or construction water associated with environmental remediation or

dewatering of construction projects. Applicants must submit flow documentation, along

with an analysis of water to be discharged. A total of 20 Temporary Discharge Permits

were issued in 2018.

Plan Check Program

Under the City’s Plan Check Program, new businesses, are required have plans reviewed

and stamped by the City’s Environmental Services Department. This program has been

implemented to protect the collection system, and ultimately the Wastewater Facility, from

pollutants. Typically, a Plan Check includes the sizing of pretreatment equipment and the

implementation of best management practices. In 2018, 36 plan checks were performed.

Of these plan checks, four were dental facilities, 18 were industrial dischargers including

potential permitted facilities, seven were automotive, and seven were other types of

facilities.

Dental Amalgam Program

Identified as a controllable source of mercury entering the collection system, wastewater

from dental practices continues to be monitored through the City’s Dental Amalgam

permitting and inspection program. Implementation of a dental program to issue Dental

Wastewater Discharge Permits began in 2009 and continued during 2018. The new Federal

Dental Amalgam Rule was published in June 2017 and updates to the Sewer Use Ordinance

are planned to ensure consistency with the new rule. The new rule went into effect July 14,

2017 for new dental dischargers and will go into effect July 14, 2020 for existing dentists.

The Dental Amalgam Program is working with dentists to help them comply with new

requirements.

5 of 5

Dental permits are issued on a five-year cycle and the program continues to reissue permits

to dental practices in compliance with program requirements whose five-year permits were

to expire. The Dental Amalgam Program issued 32 new permits and 61 renewals in 2018

to dentists in the Tributary area, bringing the total number of permitted dental practices in

the program to 856. The program has an extensive discharger identification program, which

includes several methods for identifying new dental practices.

Requirements of the Dental Amalgam Program include certification of implementation of

dental amalgam best management practices and installation of an amalgam separator.

Amalgam Separator Installation and BMP Certifications have been received from 96% of

dental practices. Dental Amalgam Program BMP and amalgam separator certifications are

available for download on the City’s website at: http://www.sanjoseca.gov/dental

Permit holders are inspected for compliance a minimum of once during the five-year permit

cycle. Inspections in 2018 confirmed that amalgam separators were installed at over 99%

of these practices, verifying the accuracy of their previously submitted self-certification

statements. The remaining 1% represents newly identified dental facilities. Inspections of

dental practices will continue in 2019. The Dental Amalgam Program identified 46

violations from dental practices in 2018. The majority of these were amalgam separator

maintenance related. All violations were enforced and resolved.

Other Pollutant Reduction Activities

The San José-Santa Clara Regional Wastewater Facility implements programs to reduce

pollutants from nondomestic users that are not classified as SIUs. Information for this

section can be found in the 2018 Annual Pollution Prevention Report on the City’s website:

SAN JOSE-SANTA CLARA REGINONAL WASTWATER FACILITY 2018 SECOND SEMIANNUAL INDUSTRIAL USER VIOLATION REPORT

I. SAMPLING PROCEDURES

A. SAMPLE LOCATIONS 1. Influent - Influent samples are collected from the raw sewage wet well by automatic sampler

and grab sampling. This location corresponds to Station INF-001 as set forth in the Wastewater Facility’s NPDES Permit, CA-0037842.

2. Effluent - Effluent samples are collected from the effluent wet well by automatic sampler and grab sampling. This location corresponds to Station EFF-001 as set forth in the Wastewater Facility’s NPDES Permit, CA-0037842.

3. Biosolids – Biosolids samples are collected from the Sludge Management Facility drying beds for this monitoring period.

B. COLLECTION TIMES

1. Automatic Sampling - Automated sampling is performed using flow-proportioned, compo-site samplers that operate from midnight to midnight on consecutive days. Influent and ef-fluent samples are taken during the same 24-hour period.

2. Grab Sampling - Grab samples are collected at a time corresponding to the Wastewater Facility’s maximum peak flow at 12:30 hours.

3. Biosolids Sampling - Biosolids samples are collected if available, in February and August and within the same twenty-four hour period as when influent and effluent samples are col-lected.

C. COLLECTION METHOD

1. Direct Collection - Wastewater samples for volatile organic compounds, semi-volatile or-ganics, pesticides & PCBs, mercury and cyanide analyses are collected as grab samples dur-ing Facility’s projected peak flow. Samples for the analysis of volatile organic compounds (VOCs) are collected in 40-mL glass vials with Teflon®-lined septum and screw caps. The vials are filled to overflowing before being capped to avoid any headspace. Semi-volatile organic samples (BNA-base, neutral, acids) are collected in 1-liter amber glass bottles with Teflon®-lined screw caps. Pesticide/PCB samples are collected in 1-liter amber glass bottles with Teflon®-lined screw caps. Mercury samples are collected utilizing clean hands techniques in 1-liter acid-rinsed amber glass bottles with Teflon®-lined screw caps. Cyanide samples are collected in 2-liter amber plastic containers.

2. Automatic Collection - Wastewater samples for metals analyses (excluding mercury) are collected using automated composite samplers. Samples are collected over a 24-hour period based on flow into plastic carboys within refrigerated samplers. Aliquots taken from the car-boys for metals analysis are poured into 1-liter certified clean plastic bottles.

3. Biosolids Collection – Biosolid samples are collected from the Facility’s drying beds by employing a grid pattern map for sample locations. Biosolid samples are collected directly into 250-ml borosilicate glass jars.

2

D. STORAGE, PRESERVATION, AND HOLDING TIMES 1. EPA Method 624 - Samples for volatile organic compound analysis are tested for residual

chlorine and treated with sodium thiosulfate if present, stored at zero to six degrees Celsius and analyzed within three days of collection.

2. EPA Method 625 - Samples for semi-volatile organic compound analysis are tested for re-sidual chlorine and treated with sodium thiosulfate if present, stored at zero to six degrees Celsius, extracted within seven days of collection and analyzed within forty days of extrac-tion.

3. EPA Method 608 - Samples for pesticide/PCB analysis are tested for residual chlorine and treated with sodium thiosulfate if present, adjusted to a pH range of 5.0 to 9.0 with sodium hydroxide solution or sulfuric acid as needed, stored at zero to six degrees Celsius, extracted within seven days of collection and analyzed within forty days of extraction.

4. Mercury – Samples for total mercury analysis are preserved with 5 ml/L of BrCl solution and analyzed within 90 days of collection.

5. Metals – Samples for metals analysis (excluding mercury) are preserved with nitric acid to pH <2 at least 24 hours prior to analysis and analyzed within six months of collection.

6. Cyanide – Samples for cyanide analysis are checked for and, if present, treated for oxidizers and sulfides prior to preservation to pH>10 with sodium hydroxide, stored at zero to six degrees Celsius and analyzed within 14 days of collection.

7. Biosolids – Samples are stored at zero to six degrees Celsius; hold times vary with the ana-lytical method application. Mercury samples are analyzed within 28 days of collection; for all other metals, samples are analyzed within six months of collection. Samples for cyanide and for all organic analyses including organochlorine pesticides, PCBs, semi-volatile organ-ics, and volatile organics, are analyzed within fourteen days of collection.

II. METHOD OF SAMPLE DECHLORINATION

A. EFFLUENT SAMPLES Dechlorination of effluent samples is not required since the samples are collected downstream of the Facility’s dechlorination process. The Facility uses sodium bisulfite injection for dechlorina-tion.

B. INFLUENT SAMPLES Influent may be pre-chlorinated at various times as an odor control measure. Sodium thiosulfate is used as a dechlorinating agent when necessary.

III. SAMPLE COMPOSITING

A. INFLUENT AND EFFLUENT SAMPLES Priority Pollutant Metals - Samples for priority pollutant metals analysis, except mercury, are composited by automatic samplers based on the Facility’s flow rates. Volatile organics, semi-volatile organics, organochlorine pesticides/PCBs, mercury, and cyanide samples are collected by grab sampling during the Facility’s projected peak flow period.

B. BIOSOLIDS Twenty grab samples are collected and then composited, using equal parts by weight, into a single sample; the composited sample is divided into appropriate portions for the individual analyses required.

A. DRY-WEATHER SEASON SAMPLING – AUGUST, 2018 See Appendix I - Data Tables.

VI. DISCUSSION OF RESULTS

A. INFLUENT DISCUSSION

Base Neutral Acids (BNA) EPA625 Phenol is used as a precursor in a number of industrial synthesis applications to produce resins, plastics, surfactants, detergents, emulsifiers, insecticides, and medical antiseptics. Other uses of phenol include anesthetic applications in ointments, ear and nose drops and cold sore lotions; and as a slimicide for bacteria and fungi growth. Phenol was detected and reported at 12.1 µg/L. Para Cresol (P-Cresol) can be found in petroleum products, artificially produced from auto and diesel emissions, coal production wastewater, disinfectants, metal refining, and chemical manu-facturing. P-cresol was detected and reported at 39 µg/L. P-cresol is not a listed CTR com-pound.

Diethyl phthalate is ubiquitous in the environment based on its many applications. It is used as a plasticizer in many products and as a solvent for cosmetics, personal care products, and insec-ticides. The degradation of this compound in an aqueous matrix is dependent on aerobic or an-aerobic conditions for its breakdown in water. Diethyl phthalate was reported as DNQ (De-tected, Not Quantified) at 2.6 μg/L. Volatile Organic Compounds (VOCs) EPA624 Chloroform may enter the environment through its use as an industrial solvent, extracting rea-gent, cleaning agent and as a by-product from the chlorination of water, wastewater, and cooling water. Chloroform is typically detected in this Wastewater Facility’s influent. Artificial or indi-rect sources of chloroform are primarily as a chlorinated by-product in water treatments, paper mills, and combustion of leaded gasoline. Chloroform was detected and reported at 2.8 µg/L. Toluene is used as a general-purpose solvent, fuel additive, and chemical manufacturing constit-uent. Considerable amounts are discharged during the emissions, volatilization, storage, transport, and disposal of fuels and oils. Toluene was detected and reported at 4.3 µg/L. Ethylbenzene is a colorless organic liquid with a sweet, gasoline-like odor. The greatest use of ethylbenzene is to make styrene, another organic liquid used as a building block for many plas-tics. It is also used as a solvent for coatings, and in making rubber and plastic wrap. Ethylben-zene is released to the air primarily from its use in gasoline. Ethylbenzene was reported as a DNQ value at 0.73 μg/L Polychlorinated Biphenyls and Pesticides EPA608 There were no detectable amounts of Aroclors (PCBs) or organochlorine pesticides for this monitoring period in the Wastewater Facility’s influent. Cyanide All influent cyanide results were reported either as DNQ values with a reporting limit of 3.0 µg/L or non-detect (ND) at the method detection limit. Priority Pollutant Metals All priority pollutant metals measured during this period were at concentrations characteristic of influent typically received by this Facility.

B. EFFLUENT DISCUSSION

Priority Pollutants for Base Neutral Acids (BNA) EPA625; Volatile Organic Compounds (VOCs) EPA624; Polychlorinated Biphenyls and Pesticides EPA608: The Priority Pollutant Organics monitoring requirement defined in Attachment E, Section VII of the Wastewater Facility’s NPDES Permit for Pretreatment and Biosolids Monitoring (Table E-5) was replaced by:

5

The Order, effective April 2016, reduced the frequency of the Wastewater Facility’s final effluent monitoring for priority pollutant organics to once per NPDES permit cycle. Therefore, no final effluent samples for priority pollutant organics were collected or analyzed for this period. Cyanide All effluent cyanide results were reported either as DNQ values with a reporting limit of 3.0 µg/L or non-detect at the method detection limit. Priority Pollutant Metals All priority pollutant metals were measured at concentrations characteristic of the effluent dis-charged by this Facility for this monitoring period. Priority pollutant metals detected and reported in the effluent were below NPDES permit limitations. All detectable concentrations are below applicable Water Quality Criteria or Objectives.

C. BIOSOLIDS DISCUSSION

The concurrent collection of the Wastewater Facility’s Biosolids with influent and effluent sam-pling occurred on August 2, 2018. Twenty sample aliquots were collected, composited and sub-sequently analyzed for priority pollutant contaminants by contract laboratory services. Semi-volatile Organic Compounds (EPA8270) Bis(2-ethylhexyl) phthalate is used as a plasticizer for polyvinyl chloride and other polymers and is likely to be released to air and water during production and waste disposal of these plas-tic products. Bis(2-ethylhexyl) phthalate is carried long distances when released to air and has a strong tendency to absorb to soil and sediments. Bis(2-ethylhexyl) phthalate was reported as a DNQ value at 3.4 mg/Kg. All other analytical results for semi-volatile organics were re-ported as non-detect at the method detection limit. Volatile Organic Compounds (EPA8260) All analytical results for volatile organics were reported as non-detect at the method detection limit. Polychlorinated Biphenyls-Aroclors (EPA8082) Analytical results of PCB Aroclors (EPA Method 8082) were all reported as non-detect at the method detection limit. Organochlorine Pesticides (EPA8081) Organochlorine pesticides analysis of the Wastewater Facility’s biosolids resulted in one detected compound. 4,4’-DDE (Dichlorodiphenyldichloroethylene) is a degradation byproduct of DDT (Dichlorodiphenyltrichloroethane), formed by dehydrohalogenation or loss of hydrogen chloride. DDT is a pesticide commonly used for insect control in the United States until it was banned by the Environmental Protection Agency (EPA) in 1972. 4,4’-DDE was detected and reported at 0.033 mg/Kg, well below the Total Threshold Limit Concentration of 1.0 mg/Kg. All other ana-lytical results for organochlorine pesticides were reported as non-detect at the method detection limit. Priority Pollutant Metals Metals analysis of the biosolids resulted in additional Soluble Threshold Limit Concentration (STLC) testing for chromium and copper. The subsequent STLC values were determined to be below any actionable levels. No priority pollutant metals were detected in concentrations that would adversely affect Class B biosolids disposal options.

NV The violations were for prohibition on use of diluting waters, failing to provide adequate pretreatment, failing to screen industrial waste, discharge of solid or viscous matter, and for failing to provide an adequate monitoring point. The IU responded to the violations by plumbing the diluting waters downstream of the sample point and adding treatment, as verified by an inspection on 12/17/2018. See 8/8/2018 Compliance Meeting for additional details.

CM At a Compliance Meeting on 8/8/2018, the violations and Compliance Agreement were discussed. The IU responded to the violations by adding treatment and replumbing diluting waters. In addition to these requirements, the IU was required to conduct an engineering evaluation for treatment system and monitoring equipment improvements, write SOPs for the new equipment, and train employees. An inspection on 12/17/2018 verified the additional treatment, replumbing of diluting waters, and repairs to the monitoring equipment.

NV The violations were for failing to meet the federal and local pH limits, as noted on the IU’s pH chart recorder, failing to notify of violations, and failing to comply with a permit condition - failure to maintain a continuous pH monitoring equipment. A total of 21 pH violations with durations of one minute to 33 hours were identified during inspections on 12/6/2018 and 12/18/2018. The IU failed to report the pH violations within 24 hours. The causes of the violation were determined to be an insufficient treatment system flow diversion setup, a malfunctioning electronic pH alarm notification system, failure to follow notification procedures, and inadequate procedures for maintaining a continuous pH record. The IU responded to the violations by repairing the pH alarm notification system and retraining staff. In addition, the IU will be adding a pH probe in a new location to actuate the emergency diversion valve in the first quarter of 2019. A Compliance Meeting is scheduled for 2/20/2019.

NV The violations were for failing to meet the federal and local pH limits, as noted on the IU’s pH chart recorder, failing to notify of violations, and failing to comply with a permit condition - failure to maintain a continuous pH monitoring equipment. A total of 21 pH violations with durations of one minute to 33 hours were identified during inspections on 12/6/2018 and 12/18/2018. The IU failed to report the pH violations within 24 hours. The causes of the violation were determined to be an insufficient treatment system flow diversion setup, a malfunctioning electronic pH alarm notification system, failure to follow notification procedures, and inadequate procedures for maintaining a continuous pH record. The IU responded to the violations by repairing the pH alarm notification system and retraining staff. In addition, the IU will be adding a pH probe in a new location to actuate the emergency diversion valve in the first quarter of 2019. A Compliance Meeting is scheduled for 2/20/2019.
