Per these Permit Amendment applications, the SBMWD requested to operate EPA Well 1 08S and to treat water produced by this well through the existing 19th Street North Granular Activated Carbon (GAC) treatment plant prior to delivering to the distribution system.

Newmark Groundwater Contamination Superfund Site

Groundwater supply of the SBMWD is extracted from the Bunker Hill Groundwater basin. The western portion of the Basin has been contaminated with volatile organics mainly with trichloroethylene (TCE) and tetrachloroethylene (PCE). Other contaminants may be present in addition to TCE and PCE. All constituents of concern (COGs) are listed in Table 2. COGs are constituents, which have been either detected in the upgradient monitoring wells of the Newmark!Muscoy plume or may be a concern associated with PCE, TCE, or 1,1, 1-TCA contamination.

The groundwater plume started from the North end of San Bernardino and moved southward. When the plume reached the Shandin Hills, it divided into two arms: the Newmark plume on the east side and the Muscoy plume on the west side. The Newmark/Muscoy plume has impacted over one-third of the SBMWD's groundwater supply. The contamination was discovered in the early 1980s. Groundwater contamination in the Muscoy OU area is present in the shallow aquifer and in the intermediate zone. The contaminant distribution in the Muscoy OU area contrasts with the Newmark OU area, where more contamination is present lower in the deep aquifer.

In the late 1980's the State provided money for the construction four ground water treatment sites, which are Waterman PTA, Newmark PTA, 1ih Street GAC and 191h GAC, to remediate the problem. Studies have shown that drilling wells outside of the plume boundaries would spread the contamination. To address these problems, the SBMWD entered into agreement with the United State Environmental Protection Agency (US EPA) to construct facilities to manage the identified contamination. The Newmark Project is an US EPA Superfund Remedial Action project that manages the cleanup of eight square miles of contaminated groundwater.

The Newmark Project utilizes a large "pump and treat" system to extract contaminated water from three barriers within the contaminated basin and treats this water using GAC and Packed Tower Aeration (PTA) technologies to remove the contaminants. The treated water is then delivered to the SBMWD for domestic water use. The EPA administers the Newmark Project (or the Newmark Groundwater Contamination Superfund Site) under the Comprehensive Environmental Response, Compensation & Liability Act (CERCLA). The EPA Newmark Project consists of three Operable Units (OU), which are the Newmark OU, the Muscoy OU, and the Source OU. The SBMWD with the assistance of the DTSC has entered into a Cooperative Agreement with the USEPA to construct and operate the Newmark OU and the Muscoy OU. The Newmark OU has been in operation since October 1998. The Muscoy OU has been in operation since November 2004. The Source OU is being investigated by the USEPA.

The selected remedy for the Muscoy OU includes groundwater extraction wells and a treatment plant to remove VOCs from the extracted groundwater, which will then be served as portable water by the SBMWD. The Muscoy o·u includes five EPA extraction wells, which are EPA Well Nos. 108, 109, 110, 111, and 112. These wells were drilled in the leading edge of the contaminated aquifer in order to halt further down gradient migration to the southeast. These wells extract contaminated groundwater from the

aquifer, remove the contar:ninants through the 19th Street GAC treatment facility prior to delivering portable water to the SBMWD distribution system. These wells are screened through the intervals of contamination. The Muscoy OU also includes five monitoring wells, which are MW 135-139. These monitoring wells are located down-gradient of the Muscoy plume front extraction well network (MV 135-139 are located approximately 1,500 feet down gradient of these five EPA extraction wells). Contaminant performance for the Muscoy OU is based on evaluating reported VOC concentrations for groundwater samples collected from these monitoring wells. VOCs and COCs have been tested every quarter for each EPA extraction well. TCE, PCE, Freon 12, and c-1 ,2 DCE have been detected. The results of detected COCs at Muscoy plume extraction wells are summarized in Table 3. The results of detected COCs at Newmark plume extraction wells are summarized in Table 4. Freon 11 has been detected sometimes and the highest level detected was 1.1 ~g/L. Other COCs have not been detected in EPA extraction wells.

In addition to COCs, the SBMWD has been tested 1 ,4-dioxane and butene every quarter since April 2000 for EPA Wells 1-7 and since April2005 ior EPA Wells 108-112. In according to SBMWD's letter dated May 30, 2001, butene has been monitored


because it was detected in the past in up-gradient monitoring wells WMW01 H-01 C, WMW011-01 C, and WMW01J-01 Cat levels below the detection limit (DLR). 1 ,4-dioxane has been monitored as recommended in the permit No. 03-13-99P-002 issued in 1999. Butene and 1 ,4-dioxane have not been detected at any EPA extraction wells. SBMWD informed that EPA collected 1 ,4-dioxane samples from Muscoy OU (up-gradient and down-gradient of Muscoy OU extraction wells) and Source OU during multiple sampling ·events in 2006 and 1 ,4-dioxane was not detected above the reported sample quantitation limit or detection limit, which is 20 j..Jg/L. SBMWD informed that EPA has never required SBMWD for butene or 1 ,4-dioxane monitoring at EPA extraction wells.

Levels of PCE and TCE detected show decreasing trends in EPA Wells 109-112 and increasing trends in EPA Well 108. EPA Wells 109-112 captured a portion of the plume. But EPA Well 108 pumps groundwater from the deeper aquifer, at depths below 510 feet below ground surface, and it consequently has little or no effect on capture in the shallow aquifer. According to Muscoy OU Semiannual Data Evaluation Summary Report dated April 2007 for a period from February 2006 through July 2006, the increasing PCE trends in EPA Well 108 may indicate that the shallow contamination at EPA Well 108 is being drawn into the deeper aquifer because of the absence of pumping in the shallow aquifer at this location. Conversely, it may indicate that EPA Well 108 may simply be drawing in deeper contamination (from the Newmark OU plume) that the other Muscoy OU wells do not capture. A new well, which is EPA Well 1 08S, was recently installed to establish pumping capacity in the shallow interval at the EPA Well 108 site. The EPA Well 1 08S is located approximately 20 feet from the existing EPA Well 108. The screen intervals for EPA Wells in the Muscoy plume are listed in Table 5.

Well Structure:

EPA Well 1088 was drilled as a domestic water supply and also for extraction purpose. The drilling stared in December 2006 and finished in March 2007. The well was drilled in the leading edge of the contaminated aquifer in order to halt further down gradient

City of San Bernardino Municipal Water Department Engineering Report-Permit Amendment 05-13-07PA-013 Page 6 May 14, 2007

migration. The well .extracts contaminated groundwater from the aquifer, remove the VOC contaminants, and deliver portable water to the SBMWD distribution system. The USEPA is responsible for construction costs, which are administrated through URS Corp. and SBMWD. The SBMWD is responsible for constructing the well, developing the well site, and assisting in the oversight of the treatment plant and pipelines.

EPA Well 1 08S is a vertical well located approximately 20 feet from the existing EPA Well 108 in the City of San Bernardino. According to Mike Farrell with San Bernardino County Environmental Health, a Well Drilling Permit is not required because this well is a part of the Newmark Groundwater Contamination Superfund Site, which EPA administers under CERCLA. The well was drilled to a depth of 501 feet. The well was constructed with a 16.625-inch diameter steel casing to a depth of 490 feet (total depth of completed well is 490 feet). The borehole contains a 235-foot cement sanitary seal. The well casing was provided with a total length of screened interval of 145 feet. The well is equipped with a 1 05-horse power (HP) electric submersible pump rated at 650 gallons per minute (gpm).

A flow meter is provided at the discharge pipe. Other surface construction features (casing vent, air release vacuum relief (ARVR) valve, sampling tap, check valve, production meter, etc.) comply with the California Water Work Standards (CWWS). The well is located 14.5 feet from a residential home, which does not meet a minimum distance of 25 feet. The well site is fenced. Well discharge pipe of Well 1 08S connects with the discharge pipe of EPA Well 108 prior to connect to the influent pipe to the 19th Street GAC treatment facility-North Plant.

Water Quality:

Samples for Title 22 monitoring were collected for the well on February 27, 2007. Results are summarized below:

• Total coliform: Total coliform was present, but E. Coli bacteria was absent.

• Inorganic chemicals, general mineral, and general physical: Nitrate was detected at 24 mg/L as N03, which is below the nitrate MCL. Results of other constituents were non-detect or very low compared to their respective MCLs.

• Volatile Organic Chemicals (VOCs) and Synthetic Organic Chemicals (SOCs): SOCs have not been detected. VOCs have not been detected except the constituents listed in Table 3 above.

• State unregulated chemicals: This is the first round of the state unregulated chemical monitoring and the results were non-detect except for vanadium and


dichl"orodifluoromethane (Freon 12)). Vanadium was detected at 3.2 !Jg/L, which are compared to its notification level of 50 !Jg/L. Freon 12 was detected at 3.4 IJg/L, which is below its notification level of 1 ,000 !Jg/L.

• Radionuclides: Gross alpha and radium 228 have not been detected for the well. Uranium was detected at 2.1 pCi/L. ·

Compliance with National Environmental Policy Act (NEPA):

The Department received a letter dated September 7, 2004, from the USEPA, which clarifies that the EPA is not required to comply with the NEPA when administering the CERCLA, 42 U.S.C. § 9601 et. seq., commonly known as Superfund. EPA Well 1 08S is part of the Newmark Groundwater Contamination Superfund Site, which EPA administers under CERCLA. Therefore, they were not required to comply with NEPA.

Drinking Water Source Assessment

The DWSAP was completed by the SBMWD for the EPA Well 108S in March 2007. The well is considered most vulnerable to Newmark!Muscoy Plume, automobile-gas stations, chemical/petroleum processing/storage, dry cleaners, and landfills/dumps.

Detection of TCE, PCE, 1 ,2-DCE , and Freon 12 is believed to be associated with the Newmark/Muscoy Plume. Treatment for these VOC constituents is provided at the North 19th Street GAC treatment facility.

19th Street North GAC Treatment Facility

The 191h Street GAC treatment facility includes the North Plant and the South Plant. The North and South Plants have a total capacity of 22.5 MGD. Details of GAC vessels at these plants are listed in Table 6.

The South Plant consists of four pairs of 20,000-pound GAC vessels (8 vessels). Each pair consists of two GAC vessels in lead-lag configuration. Each pair is capable of treating up to 750 gpm. The South Plant has a capacity of 3,000 gpm (or 4.32 MGD). Water produced by 19th Street Well Nos. 1 and 2 is treated at the South Plant. Water produced by Mt. Vernon Well is allowed to be treated at this plant, but it is also allowed bypassing the plant when there is no detection of PCE and TCE. Currently, Mt. Vernon Well currently bypasses this treatment plant when the well is in operation.

The North Plant consists of 12 pairs of 30,000-pound GAC vessels (24 vessels). Each pair is capable of treating up to 1,050 gpm. The North Plant has a capacity of 12,600 gpm (or 18.14 MGD). Water produced by the EPA Well Nos. 001, 108, 109, 110, 111,


112, and 1 08S is treated at the north plant. Currently, these EPA wells have a total capacity of 11 ,417 gpm, which is capable to be treated at the North Plant.

The effluent of the North Plant merges with the effluent of the South Plant to meet the nitrate blending target of 36 mg/L. Nitrate on-line analyzer is provided at the combined effluent of the north and south facilities. The combined effluent of the north and south facilities are chlorinated and then discharged to the 1416 Zone (lower zone) and 258,000-gallon 19th Street reservoir, and boosted to the 1249 Zone (upper zone) for domestic use.

The Operations Plan for the 19th Street GAC treatment facility was revised in March 2007, but it does not include the nitrate blending operation, which was prepared separately in March 2005. The Operations Plan needs to be revised to reflect the minimum monitoring frequencies required, to incorporate the nitrate blending operation, and to ensure the effluent from the 19th Street GAC treatment facility as well as other GAC and PTA facilities, which are operating by the SBMWD, contains PCE and TCE levels below 0.5 ~g/L as required per the permits issued on December 30, 1999, and the permit amendment issued on November 4, 2004, to the SBMWD.

GAC Change Out:

Carbon change-out is performed by Carbon Activated Corp. When carbon change out occurs, the following procedures will be followed: toxic contaminant leaching profile (TCLP)/8240 tests, iodine test and food chemical codex for all virgin or makeup carbon.

Carbon will be changed out when TCE or PCE level confirms breakthrough has occurred and it will take up to a maximum of 14 calendar days to schedule and start the carbon change-out due to purchasing policies and carbon company delivery schedule. To ensure compliance with non-detect TCE and PCE in the treated water (for all GAC plants operating by the SBMWD), after a detection of TCE or PCE level at or above 0.5 ~g/L in the plant effluent, a confirmation sample shall be collected within three days from the time the SBMWD becomes aware of the detectable result. If detectable TCE or PCE is confirmed, the SBMWD must start scheduling for carbon change-out at all lead vessels at that plant. With considerations of time consume for the change-out, the level of TCE and/or PCE shall not last more than four calendar weeks in the effluent.

City of San Bernardino Municipal Water Department Engineering Report-Permit Amendment 05-13-0?PA-013 Page 10 May 14,2007

Chlorination:

Gas chlorine is injected into the combined effluent of the north and south facilities to maintain a 0.5 - 1.0 mg/L chlorine residual in the effluent prior to entering the 1416 Zone (lower zone) and 258,000-gallon 19th Street reservoir, and boosted to the 1249 Zone (upper zone) for domestic use. The chlorine feed system automatically adjusts the chlorine feed to match the flow rate in the treatment process. A vacuum system is utilized and auto-switchover assures a constant supply of chlorine.

Treatment staff and operating times:

The SBMWD maintains operator staff on duty 20-hour each day using two shifts with operator staff on stand-by during off hours. All EPA Wells run 24 hours a day and 365 days per year. Other SBMWD's wells run as needed. The treatment plant is scheduled to operate 24 hours per day, 365 days per year. Continuous SCADA monitoring of all systems is sent to a central SCADA control center with remote shutdown capability.

Monitoring Schedule:

Title 22 monitoring requirements for 19th Street Well Nos. 1 and 2, Mt Vernon Well, and EPA Wells 1 08S, and 108-112 are in according to the most recent Vulnerability Assessment and Minimum Monitoring Frequency Guidelines for Vulnerable Groundwater Sources prepared by the Department. In addition, special monitoring frequencies for several chemicals or group of chemicals are required for these wells and they are listed in Table 9.

Minimum monitoring frequencies required for the 19th Street Treatment Facility are listed in Table 9.

EPA Well 1 08S is constructed according to California Water Well Standards and meet the minimum horizontal distances from sanitary hazards except the residential home located at 14.5 feet from the well. However, the well is provided with a concrete wall between the house and the well. The well site is fenced and locked. This well is located at the leading edge of the contaminated aquifer in order to halt further down gradient migration of the Muscoy plume to the southeast where TCE and PCE are major concerns. Water produced by the well is treated at the 191

h GAC treatment facility to meet the drinking water standards prior to delivering to the SBMWD's distribution system for domestic purpose.

Description of System and Source

County San Bernardino System No.---'3,_,6'""'"1-"-00=3=9 ___ _

PS Code:---------

Date March, 2007

The San Bernardino Municipal Water Department (SBMWD) water system is located in San Bernardino County and serves the City of San Bernardino and portions of surrounding communities. The San Bernardino system and source wells deliver water to more then 43,000 service connections through 635 miles of water mains. Source Well EPA 1 08-S, the subject of this assessment, was constructed in 2007. It is 500 feet deep and produces approximately 650 gallons per minute. General land use in the vicinity of the source well and within its designated protection zones includes predominantly residential, commercial, industrial, and transportation activities.

The principal source and recharge area for the SBMWD water system is the Bunker Hill Groundwater Basin. The Bunker Hill basin is located at the northern end of the Santa Ana River Watershed and receives all the surface water runoff from the headwaters of the Santa Ana River, Mill Creek, and a portion of that from the Lytle Creek area. It is part of the inland valley referred to as the San Bernardino Valley located in San Bernardino County, California. The Bunker Hill basin is

roximately 11 0-square miles and encompasses approximately 89,600 acres. The basin is ~,.. ,.jhded on the northwest by the San Gabriel Mountains, on the northwest by the San Bernardino Mountains, on the south by the Crafton Hills and Badlands, and on the southwest by a low east-facing escarpment produced by the San Jacinto fault. Broad alluvial fans, which extend from the base of the mountains and hills, come together to form a broad southwest sloping alluvial plain in the central part of the valley. Aquifer(s) within the Bunker Hill area are primarily recharged from runoff from the San Bernardino Mountains, surface water discharges from the Santa Ana River and Mill Creek and groundwater underflows from the Santa Ana Canyons and Lytle Creek subbasins.

The (DWSAP) Program assumes two primary types of aquifers for groundwater sources: porous media and fractured rock. The groundwater reservoir in the Bunker Hill area is of the porous media variety and consists of alluvial deposits of sand, gravel, and boulders interspersed with lens shaped deposits of silt and clay. Generally, the Bunker Hill aquifer is considered an unconfined aquifer, however, in the southwestern part of the valley, adjacent to the San Jacinto fault, the unconsolidated deposits contain numerous clay layers that create confined and semiconfined conditions. This area is referred to as the artesian pressure zone. Dutcher and Garret (1963) determined that the separate sand and clay unites could be correlated for only short distances, but did recognize three distinct aquifers, each separated by 50 to 300 feet of clay and silt. Previous studies have determined that EPA Well 1 08-S lies above the boundary of the upper confined layer in the pressure zone.

Assessment Procedures

· assessment and vulnerability evaluation of the source well was conducted by the San Bernardino .. ..licipal Water Department (SBMWD). The following sources of information were used in the assessment: SBMWD files, State of California Department of Health Services (DHS) files, and previous studies.

DELINEATION OF GROUNDWATER PROTECTION ZONES

The SBMWD utilized the basic or default groundwater delineation model known as the Calculated Fixed Radius (CFR) method for delineating the. groundwater protection zones around the source well. The calculated fixed radius method involves drawing a circle around a well to estimate the Zone of Contribution (ZOC) for a specified time-of-travel criterion. A radius is calculated using Equation 1 shown below that is based on the theoretical volume of water that will be drawn to a well in the

~ified travel time. The input data required by the equation includes the pumping capacity of the ,, the total screened interval of the well, and the effective porosity of the aquifer. The time-of-travel

periods used are 2, 5, and 10 years. The protection zones determined by the calculated fixed radius are circles centered upon the source well.

INVENTORY OF POSSIBLE CONTAMINATING ACTIVITIES (PCA's)

The purpose of the inventory of Possible Contaminating Activities (PCA's) is to identify the existence proximity of the activities that may be a potential threat to the source water supply. PCA's

u.~luded activities that use, store, transport, produce, or dispose of chemicals that have the potential to contaminate groundwater. It is important to identify historic activities as well as those currently taking place.

The PCA inventory was conducted by obtaining and compiling available information from various local and state agencies and through onsite field work. A Geographic Information System (GIS) was created for the DWSAP project in order to compile and map the PCA inventory data.

The PCA's can be classified as point PCA's, such as gas stations and junkyards, and non-point PCA's, such as sewer collection systems and transportation corridors. The location and types of most of the point PCA"s were recorded by means of field visits.

The PCA inventory, potential risk ranking and delineation of protections zones for this source well are presented in the attached source assessment forms and accompanying assessment map.

Discussion of Vulnerability

~the initial inventory of Possible Contaminating Activities (PCA's) has been completed, a Vt..(lerability analysis is conducted to determine the types of PCA's to which the drinking water source is most vulnerable to by prioritizing the list of activities identified in the inventory. The vulnerability analysis incorporates the types of PCA's identified in the inventory, their respective Risk Rankings, the Zone(s), and the Physical Barrier Effectiveness determination. These factors are used to develop a listing of types of PCA's and to determine the types of PCA's to which the drinking water source is most vulnerable. The results of the vulnerability summary for this source are listed above. Other possible contaminating activities can be found listed in the prioritized vulnerabilities list further in this report.

To prevent contamination of the drinking water supply, it is recommended to develop and implement a drinking water source protection program for the area. The recommended management measures by DHS, outlined in section 5, of the DHS DESAP Program Document, could be used for development of the protection program.

The prioritized list from the vulnerability analysis may be used in developing protection measures to address activities that are most significant to the water supply. However a detailed review of specific characteristics of each PCA is necessary to develop appropriate mitigation measures. Several mitigation measures have previously been adopted and implemented for this water system's wells. These measures include the following:

Sanitary seals have been constructed to prevent chemicals and degraded surface and groundwater from moving through the well borings and coming in contact with the groundwater source. Large concrete slabs constructed around the wellheads. The ground surface had been clopped to drain away from the wells. Large control zones have been established around the wells.

Completed by San Bernardino Municipal Water Deaprtment Date March 2007

Use the DHS Well Data Sheet (separate document) to complete the following form.

Directions:

1. Read through the form and collect the information needed to complete the form. (Hydrogeology, Soils, Presence of abandoned or improperly destroyed wells, Well construction and operation.)

2. Determine Parameter A, Type of Aquifer. • If the aquifer is confined, use the right-hand column, and evaluate only the parameters

indicated for confined aquifers. • If the aquifer is unconfined, semi-confined, or the degree of confinement is unknown, or if

the aquifer is fractured rock, use the left-hand column and evaluate only the parameters for unconfined aquifers.

3. For each parameter appropriate for the source, place a check in the box for the answer that most closely applies to that source. If more than one answer is possible, select the more conservative (i.e. lower points) answer. [For example, if the depth to static water (Parameter D) has varied between 45 and 55 feet, choose answer 2 (20 to 50 feet).] ·

4. Add the points in the column appropriate for the source and interpret the score as shown on the bottom of the last page.

Determine whether the source has a High, Moderate or Low Physical Barrier Effectiveness. Use this in the Vulnerability analysis. The higher the points, generally the more effective the source and site are to retarding the movement of contaminants to the water supply.

NOTE: If the source is located in fractured rock the source is considered to have a Low Physical Barrier Effectiveness, regardless of the point total. So, if Parameter B, Aquifer Material is 3, the remainder of the form does not need to be completed.

Rc: Newmark Groundwater Contamination Superfund Site -~ Muscoy Operable Unit.

Dear Ms. Tran:

·At the request of Dr. Kim Hoang, Remedial Project Manager for the Newmark Groundwater con.tatni.n.a.tion Superfund Site, lam writi.ng to clari.:ty tl:lat the Environm;ntal Protection Agency (HEPA") is not required to comply with the National Environmenta~ PoHcy Act ~"~PA'') whc:n. adm.inistoring the Comprehensive Environmental Rcspo112c, Compe112ation & Ltablltty Act ('~CERCLA"), 42 U.S.C. §§ 9601 et. ~commonly known as Supe~d. Specifically, EPA '~as not required to comply with NEP A in selecting a. remedy and is~uing a Record of Decision ("ROD") for the Muscoy Operable Unit groundwater contarninatior.

\ i

The Muscoy Operable Unit is part of the Newmark Groundwater Contaminatiof1 Superfund Site, which EPA administers under CERCLA. The selected remedy for the !Muscoy Operable Unit includes groundwater extraction wells and a treatment plant to remove contaminants from the extracted groundwater; which will then be served as potable water by the City of San Bernardino. The final Muscoy Operable Unit treatment system includes five extraction wells (EWIOS-112)~ five monitoring wells (MW135-139)~ a raw water pipe~ine connecting the extraction wells to the treatment plant on l91

h Street, expansion of the e~isting 19th Street plant to accommodate the new volume of water to be treated> and a booster ~ta.tion at 9th Street to connect the City of San Domardino Water Department di~Stribution system :to the distribution system of the San Bernardino Municipal Valley Water District.

, EPA follows CERCLA when selecting remedies at Superfund sites. CERCLA iaims to benefit the environment by providing for the cleanup of hazardous waste sites, and es~blishes

specific procedures and requirements that EPA must follow in selecting remedies for s*ch sites. By contrast, NEPA is a gem.etallaw thnt requires federal ugencica to cn.suro that thoy co;nsidcr the environmental implications of federal projects. (As you know, the California Environ.rhental Qn~lity A~t ("CEQA'') is the California state law counterpart to NEPA.)

1

It is well-established that a federaJ agency is not required to comply with. NEP A!. when the agency is engaged primarily in environmental matters, and its own legislation mandatd a process for considering the environmental implications of its actions. In that case, the agency'~ own· legislation is deemed to provide the "functional equivalent" to compliance with NEPAJ ~ Alabama v. EPA, 911 F.2d 499> 504 (11th Cir. 1990). CERCLA provides the function~] equivalent to NI::W A; it is focused primarily on environmental issues and mandates a pri;.cess for considering environmental implications .as part of the remedy.selection process. Becau!se , CERCLA provides the functional equivalent to NEP A, EPA was not required to follo~ NEP A in selecting the remedy for the Muscoy Operable Unit groundwater contamination.

I hope this has clarified any question regarding EPA compliance with NEPA at ~he· Newmark Groundwater Contamination Superfund Sito. If there are any questions, plealse do not hesitate to contact Ms. Hoang at ( 415) 972-3147.

19th Street (EPA Muscoy OU Plant) 4.3 MGD Expanded to 22.5 Liquid Phase Granular Activated Carbon

Treatment Plant Operations Plan

Background to the Original 19th Street T~eatment Plant:

The original 19th Street treatment plant and reservoir site is located on a one-half acre site at 1820 W. 19th Street, San Bernardino, California, 92411. The plant treats 4.32 MGD of low level (under 25 ug/L) PCE/TCE contaminated groundwater. It can be delivered to the 25 8,000 gallon 19th Street booster clear well, delivered directly to the Lower Zone (1249 Elevation) or boosted directly to the Upper Zone (1416 Elevation) for domestic use. The 19th Street plant consists offour (4) pairs (eight (8) vessels) of granular activated carbon (GAC) vessels. The 19th Street plant was permitted in 1995 by the California Department of Health Services (DHS), and is currently treating water from two existing San Bernardino Municipal Water Department (SBMWD) contaminated wells. The plant vessels will operate in series (dual pass) to ensure maximum treatment reliability and full carbon utilization.

Background to the Expanded 19th Street Treatment Plant:

Under the Muscoy OU Groundwater Contamination Superfund Project in 2004, SBMWD completed five (5) wells (EPA 108, 109, 110, 111 and 112) in the leading edge ofthe contaminated aquifer in order to halt further down gradient migration and expanded the 19th St GAC Plant to 22.5 MGD to clean up contamination in the Muscoy OU groundwater plume adding another 3.5 acres to the original plant. The United States Environmental Protection Agency (EPA) Record of Decision (ROD) states that the well discharge of the treated water will meet drinking water standards (maximum contaminant level or MCL) utilizing the existing and expanded 19th Street GAC plant as potable water. The five new wells along with EPA Well 1 (currently part of the Waterman GAC Site) will be utilized to accomplish the clean-up. EPA Well 1 treatment will be shifted to 19th St GAC to unload the current Waterman Plant which is operating at maximum capacity. The existing SBMWD wells (19th Street No.1 & 2) will also be treated through the original GAC Vessels.

Remedial action as outlined by the ROD began in 1998 with a provisional permit and then DHS permitted (Water Permit No. 03-13-99P-002) the use of Newmark OU for domestic use after treatment. In November 2004, DHS permitted (Water Permit No. 03-13-99P-002 amendment #4) the use of the EPA Wells 1, 1 08, 1 09, 110, 111 and 112 for domestic use after treatment through the 19th St GAC treatment plant. In April 2005, 19th St GAC treatment plant along with above mentioned wells began operation on a 24-hour, 365 day per year basis.

During the pumping of the Muscoy OU, it was discovered that the shallow aquifer at EPA 108 site was contaminated with PCE/TCE and was migrating downstream of the barrier wells. In January

1

2007, a new well EPA 1 08-S was installed to establish pumping capability in the shallow interval at the EPA 108 site location. The well is 16" in diameter and 490' deep with 0.060" slot screen between screened intervals from 265' to 285', 305' to 350' and 370' to 450' by design. It was designed to pump between 525GPM and 625 GPM.

The following Treatment Operations Plan has been developed to include the EPA Wells 1, 108, 108-S, 109, 110, 111, 112, 19th Wells 1 & 2, but limits the flow not to exceed the GAC Design.

See (Attachment 1 Operator List)

2. Raw Water Monitoring Schedule:

All water wells will be sampled as follows:

a. Monthly - Bacteriological b. Quarterly - PCE/TCE c. Quarterly- Nitrate (If levels are at or above 22.5 mg/L as N03) d. Semiannually- Full VOA e. Annually nitrate (N03) f. Every three years for full Title 22 including inorganic, organic, general mineral, general

physical, MTBE, perclorate, and VOCs g. Every three (3, 6, 9) years- Gross Alpha (dependant on gross alpha level data) h. Every four (4) years- Unregulated VOCs,(dependent on DHS waiver) 1. Every six (6) years- SOCs (dependent on DHS waiver)

All testing results are submitted to the DHS electronically and a paper copy is kept in date order by plant at the SBMWD facility located at 195 North "D" Street and is available for review upon request. They are also kept in the Groundwater Data Manager (GWDM) database in an electronic format.

3. Water Quality in Treatment Plant:

The following is a list of tests conducted on combined raw water and on combined treated water for sample monitoring:

a. Daily - Chlorine residual test two times each day. b. Monthly- Bacteriological; at combined effluent before chlorination. c. Monthly- Bacteriological; at lead vessel effluent before chlorination. d. Monthly - PCE/TCE; at lead vessel effluent before chlorination. e. Bimonthly- PCE/TCE at 50% of MCL; at lead vessel effluent before chlorination. f. Weekly- PCE/TCE at 75% of MCL; at lead vessel effluent before chlorination.

2

g. Quarterly- PCE/TCE; combined raw water at plant site and treated water before chlorination. h. Semiannually - full VOA; at combined effluent before chlorination.

See (Attachment 2 Full VOA)

All testing results are submitted to the DHS electronically and a paper copy is kept in date order by plant at the SBMWD facility located at 195 North "D" Street and is available for review upon request. They are also kept in the Groundwater Data Manager (GWDM) database in an electronic format.

1. Alarms and Shutdown Capabilities:

All GAC vessels operate in a dual pass mode with interim sampling between vessels for protection against breakthrough. Each vessel has a high pressure rupture disk to avoid over pressurization. The GAC system has a differential pressure gauge between the influent and effluent that notifies operators of changes in vessel pressure.

The SBMWD maintains operator staff on duty 20-hours each day using two shifts with operator staff on stand-by during off hours. Each treatment site is visited at least once each shift where chemical feeds, flow rates, chlorine residual, and security checks are done. On-site plant shutdown and emergency chlorination procedures are posted and all operators are trained for an on-site plant shutdown. All sites containing chlorine comply with the Cal/ ARP accident prevention plan. Continuous SCAD A monitoring of all systems is sent to a central SCAD A control center, located at 195 North "D" Street, with remote shutdown capability. The following forms for monitoring have been placed in the Attached Forms section of this plan:

Chemical Dosage Monitoring:

All treatment sites utilize a dual tank auto-switch-overflow-paced gas chlorinator to maintain a 0.5-1.0 mg/1 chlorine residual in the treated effluent. These systems use four on-site 150 pound chlorine cylinders on scales with a manual_set flow paced dosage control set between 0.5 - 1.0 mg/1. The chlorine feed system automatically adjusts the chlorine feed to match the flow rate in the treatment process. The chlorine residual is also checked two times each day, adjustments are made if required and demand changes are noted and records are kept. A vacuum system is utilized and autoswitchover assures a constant supply of chlorine.

Chlorine feed concentration is calculated as follows:

lbs CL2 = (MGD x 8.34 x mg/1)/(% Strength)

Other checks to make sure the chemical feed system is working include:

a. Scales for chlorine to check quantity in the cylinders. b. Quantity of chemicals used in pounds is calculated each day to make sure the use rate is in an

acceptable range.

z. Procedures for Adjusting Chemical Feeds:

Four ( 4) on-site 150 pound chlorine cylinders on scales with a manual set flow paced dosage control set between 0.5- 1.0 mg/1. The chlorine feed system automatically adjusts the chlorine feed to match the -flow rate in the treatment process. The chlorine residual is also checked two times each day, adjustments are made if required and demand changes are noted and records are kept. A vacuum system is utilized and auto-switchover assures a constant supply of chlorine.

8. Points of Application of All Chemicals:

At the 19th Street GAC plant, the chlorine is injected into the treated effluent stream prior to entering the 258,000 gallon booster clear-well, being boosted or delivered downstream. (Attachment 15-19th St Process Flow Diagram)

2_. Additional Chemical Feed Capability:

a. The SBMWD maintains a mobile flow-paced chemical feed gas chlorinator for emergency chlorination with a capacity of200 pounds per day.

b. The SBMWD maintains in stock barrels ofHTH 70% strength calcium hypochlorite which can be placed directly into the booster wet well and blended with the feed water.

c. The SBMWD maintains in stock a supply of 12% strength sodium hypochlorite solution with injection equipment for emergency use at plant sites.

10. Start-Up and Shutdown Procedures:

GAC Operating Manuals are maintained by the SBMWD. These manuals are consulted prior to any start-up or shutdown of the treatment plant. An understanding of the Critical Alarms Section of this Plan is also necessary to perform a start-up or shutdown. In general, the following procedures apply to initial start-up and shutdown.

11. Well Disinfection (Attachment 16 Well Chlorination):

a. The well shall be flushed prior to disinfection (full flow rate for minimum of20 minutes to waste).

b. Chlorine in the form of 12% strength liquid chlorine or 70% strength HTH will be poured down the pump discharge air vacuum valve and the well casing sounding tube with a flow of potable water to achieve a calculated 1 00 PPM chlorine concentration in the submerged portion of the well column and well casing.

c. Surge well without discharge to waste to mix chlorine and contact the nonsubmerged portion ofthe pump column.

d. Take a Cl2 residual after surging with a minimal discharge to waste. e. Rechlorinate well and/or increase residual as required to achieve desired dosage. f. Allow well to sit at least 24 hours. g. Surge well to collect sample of residual chlorine. If no chlorine residual (less than 0.5 mg/L)

is present, flush, sample, and rechlorinate as outlined above. h. If there is no chlorine residual present than redo all of the above steps. 1. Ifthere is chlorine residual of5.0 mg/1 or greater, then flush well until there is less than 0.2

mg/1 chlorine residual and collect a bacteria sample. J. Upon confirmation of no bacteriological contamination present, the well can be placed in

service.

12. Plant Start-Up:

13.

14.

a. See Carbon Change out Checklist- (Attachment 17 Carbon change out checklist) b. Set valves to drain from GAC vessel effluent. c. Start wells to plant and waste to drain. d. Collect-appropriate GAC vessel effluent samples and shut down or continue to treat to waste

until laboratory confirmation of no bacteriological contamination present. e. Switch GAC vessel valve from waste to the water treatment system. f. Check effluent stream for water quality, (i.e., color and turbidity).

a. b. c. d.

Plant Shutdown:

Plants are designed for system cycling and can be down for short durations (24-72 hours). Switch valve so vessel effluent goes to drain. Shut off supply flow to the vessels. Shut valves to drain leaving vessels full of water.

Carbon Change-out:

State Health Permit for the City of San Bernardino Municipal Water system (Water Permit No. 03-13-99P-002 dated December 1999) states "The effluent from all GAC and PTA treatment sites shall not exceed applicable MCL's or Action Levels for all constituents of concern, except Tetrachloroethylene (PCE) and Trichloroethylene (TCE), which shall be nondetect. However, during the breakthrough period some contaminate level has to occur in the effluent to assure breakthrough and not waste carbon. In December 2006, after 6 years of operation SBMWD made a request to DHS to eliminate the nondetect rule and allow a combined effluent contaminate level between 0.8 and 1. 0 ug/L at which time complete breakthrough will be declared and initiate a carbon change-out. The list of constituents of concern shall be updated and promptly reported to the Department

whenever concentrations of known contaminants increase or new constituents are found in the aquifer contaminants. The list of constituents of concern shall be included in all GAC and PTA operations plans.

PCE/TCE will be Sampled Monthly on all Lead Vessel Effluent until it reaches 50% of the MCL (2.5 ug/L) at which time bimonthly sampling will be required. When levels reach 75% of the MCL (3.75 ug/L) weekly sampling is required. (Note: State Health Policy memo 97-007 Granular Activated Carbon (GAC), Monitoring Procedures for GAC Filters states to "have the lab reports from the previous week's results to you before you collect the subsequent weekly sample") this has not been feasible, however preliminary data is furnished for review.

Plant Breakthrough: Breakthrough will be declared when either chemical constituent PCE or TCE level of the Plant's combined effluent is confirmed by the lab as equal to or greater than .8 to 1.0 ug/L.

6

Carbon will be changed out when PCE/TCE levels confirm breakthrough has occurred as described above. It may take up to a maximum 14 calendar days to schedule and start the carbon change-out due to the purchasing policies and carbon company delivery schedules. Once breakthrough has been declared combined effluent sampling will continue on a weekly basis to ensure compliance with the State Health Permit during the 14 calendar day carbon procurement period. This combined effluent contaminate level is 20% of the MCL and past data shows that carbon has been replaced before reaching 25% of the MCL. ·

Operators will attempt to maximize loading, by shifting flow from vessels above 2.5 ug/L to vessels lower than 2.5 ug/L to maximize carbon usage without exceeding the vessel design rates. These efforts will help to maximize carbon usage ..

15. Flow Variations and Loading Rates:

The 19th Street GAC plant is designed to treat 22.5 MGD up to 250 ug/L PCE/TCE to a level of nondetect. There is four (4) pair of vessels each operating in series at 750 GPM and 12 pair of vessels operating in series at 1050 GPM with the EPA wells added to the combined influent stream for the GAC vessels. The EPA wells have variable speed drives and can each operate in the range of 1.44 to 4.32 MGD depending on the well (see capacity below) but the combined flow will not exceed the treatment system design of 22.5 MGD. 19th St Well No.1 & 2 will be utilized on an as needed basis.

The following well production table applies to the 19th Street GAC plant:

Name Capacity Range (GPM)* Capacity (MGD) Run Time (hrs/day)

EPA 1 1300- 1800 1.87-2.59 24 EPA 108 1300- 1400 1.87- 2.01 24 EPA 108-S 525-625 0.76-0.90 24 EPA 109 1300- 1400 1.87- 2.01 24 EPA 110 2500-3000 3.50-4.32 24 EPA 111 2500- 3000 3.50-4.32 24 EPA 112 1300- 1400 1.87- 2.01 24 .19th St No. 1 1000- 1500 1.44-2.16 as needed 19th St No.2 1000- 1500 1.44-2.16 as needed

Total 12725- 15625 17.57-21.60

The 19th Street GAC plant has the ability to treat 15,625 GPM and will normally be operated at 81% of that capacity. The 19th Street GAC plant has the ability to treat a maximum of 15,625 GPM but will normally operate at approximately 12,725 GPM or less

20,000 pound contactors - 19th Street GAC plant carbon loading is as follows:

2340 GPM I 4 pairs of vessels = 585 GPM.

7

3000 GPM I 4 pairs of vessels= 750 GPM.

Normal flow; 2340 GPM I 4 pairs of vessels= 585 GPM or 3.37 MGD total plant output. Maximum flow; 3000 GPM I 4 pairs of vessels= 750 GPM or 4.32 MGD total plant output.

Carbon area per vessel= 3.14 X 12' X 12' I 4 = 113 square feet of surface area per vessel.

Normal hydraulic loading rate per vessel = 585 GPM I 113 square feet = 5.17 gal. per square foot. Maximum hydraulic loading rate per vessel = 7 50 GPM I 113 square feet = 6.63 gal. per square foot.

Contact time range:

Pounds carbon per vessel= 20,000 lbs. - 27 lbs. per cubic foot.

Volume of carbon per pair= 2 X 20,000 lbs. I 27 lbs. per cubic foot = 1481 cubic feet.

Normal flow contact time= 1481 cubic feet X 7.48 gal. per cubic foot I 585 GPM = 18.93 minutes contact time. High flow contact time= 1481 cubic feet X 7.48 gal. per cubic foot I 750 GPM = 14.77 minutes contact time. There are 8 GAC vessels operating in series (four pair).

30,000 pound contactors -19th Street GAC plant carbon loading is as follows:

Normal flow; 10353 GPM I 12 pairs of vessels= 863 GPM Maximum flow; 12600 GPM I 12 pairs ofvessels = 1050 GPM

Carbon area per vessel= 3.14 X 12' X 12' I 4 = 113 square feet of surface area per vessel.

Normal hydraulic loading rate per vessel= 863 GPM I 113 square feet= 7.64 gal. per square foot. Maximum hydraulic loading rate per vessel= 1050 GPM I 113 square feet= 9.29 gal. per square foot.

Contact time range:

Pounds carbon per vessel = 30,000 lbs. - 27 lbs. per cubic foot.

Volume of carbon per pair= 2 X 30,000 lbs. I 27 lbs. per cubic foot= 2222 cubic feet.

Normal flow contact time= 2222 cubic feet X 7.48 gal. per cubic foot I 863 GPM = 19.25 minutes contact time.

High flow contact time= 2222 cubic feet X 7.48 gal. per cubic foot I 1050 GPM = 15.82 minutes contact time.

8

There are 24 GAC vessels operating in series (twelve pair).

The design maximum contaminant level treatable to nondetect is 250 ug/L combined PCE/TCE.

Average influent contaminate level is 8.0 ug/L combined PCE/TCE.

The maximum combined PCE/TCE contaminates measured in the leading edge well field is 8.3 ug/L measured at EPA Well No. 110.

When full breakthrough occurs on the lead vessel, the carbon will be changed out and the lag vessel will be switched to lead.

16. Backwash or Fluffing Procedures:

A backwash is conducted when the differential head loss across the lead vessels reaches 15 psi. This usually occurs between the fourth and sixth month of continuous operation. Primary purpose is to decompress the bed to reduce head loss through vessels or to slurry out the contaminated carbon. This recovers flow and keeps energy cost at a minimum. Carbon vessels are used with groundwater so little or no sludge is removed.

Backwash rate is 1.0-1.5 times loading rate= 700-1 i 00 GPM.

Backwash should expand filter bed by 35%.

Backwash run time is I 0 to 20 minutes.

Backwash effluent is discharged to the storm drain and requires a NPDES Permit.

Note: There are specific valve sequences in the manual that must be consulted to perform a backwash.

In general, the lead vessel usually requires backwashing because of bed compression or change-out and it is conducted as follows (all aboveground valves are locked for security reasons):

The lead vessel is removed from series operation by isolation ofboth influent and effluent valves and the flow is redirected to the lag vessel by valving the raw water supply to the influent of the lag vessel.

a. Shut down influent valve. b. Shut down effluent valve. c. Valve the raw water supply to the lag vessel d. Open backwash waste valve to the lead vessel. e. Open backwash supply valve slowly and regulate flow (metered to control flow rate of700-

9

1100 GPM). f. Backwash water is directed from bottom of vessel to the top of the vessels discharging to

storm drain. g. After bed expands check discharge for water clarity and slowly reduce flow. h. Shut off backwash supply. 1. Shut off backwash discharge. J. Pressurize with treated domestic water. k. Open vessel effluent to drain. 1. Turn on untreated supply to carbon vessel and discharge to waste (sample at 25%, 50% 7 5%,

and 100% through media for turbidity and clarity). m. Return to service if only required for bed decompression. n. Collect treated water bacteriological if new carbon installed. o. Upon confirmation of no bacteriological contamination present, slowly switch valve to

reservoir (opening reservoir valve while closing drain valve)

17. Frequency and Procedures for GAC Media Inspection:

The vessels are sampled as follows:

a. PCE/TCE: Monthly sampling of the lead vessels for contaminate loading at lead vessel effluent sample point, until it reaches 2.5 ug/L and then bimonthly, until it reaches 3. 75 ug/L then weekly until breakthrough.

b. PCE/TCE: Weekly sampling at combined effluent. c. COC's (constituents of concern): Quarterly for those constituents detected in up-gradient

monitoring wells will be sampled at treatment plant combined effluent. d. All VOC's (volatile organic compounds): Semiannually e. Nitrates: Sampled quarterly at treatment plant effluent. f. Chlorine Residual: 2 times per day.

A grab sample is taken annually of the carbon for a TCLP (toxic contaminant leaching profile) analyzes.

When carbon change out occurs the following procedures must be followed:

a. Meets TCLP/8240 tests. b. Iodine test. c. Food chemical codex for all virgin or make-up carbon.

The interior of all vessels are visually inspected and disinfected during carbon change out which occurs, based upon expected levels ofVOC's occurs within an 18- 24 month period.

These records are all maintained at 195 North "D" Street San Bernardino and are available for review upon request.

In addition to the daily, weekly, and monthly log sheets, the SCADA system keeps track of flow, pressure, and functional elements ofthe system. These records are kept at 195 North "D" Street San Bernardino in accordance with our records retention policy.

Log book is maintained at treatment site to log operational changes and observances.

Summary reports of production, influent VOC and bacteriological test results, and quantity of contaminate removed are reported to the DHS, the EPA, and the State Department of Toxic Substances Control (DTSC). See (Attachment 18 -Monthly Treatment Summary)

Records on water flow in and out of the plant are maintained. (Attachment 3 SBMWD Daily . Operator Run Sheets)

Any and all the SBMWD public records are available for review upon request.

19. Operating Times:

The 19th Street GAC treatment plant is scheduled to operate 24-hours per day, 365 days per year. With 16 pairs of vessels operated in series, the SBMWD expects to keep the plant on line at all times.

20. Preventative Maintenance Program:

The following preventative maintenance program has been developed for the 19th Street Treatment Plant:

Daily:

Reads taken:

Well production in 100 CF.

Plant production in 100 CF ..

11

Hour meters wells.

Plant production in GPM.

GAC Vessel production in GPM.

GAC Vessel differential pressure.

Depth-to-water levels for EPA Wells 1, 108, 108-S, 109, 110, 111, and 112 are recorded electronically. 19th St Wells 1 & 2 are recorded manually.

CL2 residuals are recorded and adjusted to minimum 0.5 mg/L. Chlorine is delivered to accommodate plant production for a minimum 3 day supply which is kept on hand at site.

Any unusual noise or sounds coming from any equipment is noted and reported to Facilities Maintenance.

Monthly:

Depth-to-water levels from running supply wells are checked and recorded. Packing on water lubricated pumps and boosters are to be checked ~nd adjusted as required.

Automatic control valves are to be checked andY-strainers cleaned.

Biannually:

Electrical panels shall be inspected for cleanliness and cleaned as needed. All indicator lights shall be inspected and replaced as required. Reservoir indicator level transducer and actual level (SCADA system) shall be compared and adjusted accordingly.

Sumps and pits shall be inspected and cleaned if needed.

Annually:

All wells are to be pump tested for efficiency. Facilities Maintenance shall be notified of any significant change in efficiency.

All plant valves are to be exercised and condition noted repair as necessary.

All electrical connections shall be inspected and tightened accordingly. Large

12

connections shall be checked for heat with IR meter.

All motors shall be volt and amps checked for imbalance and recorded. Motor condition should be noted and recommendation given to Facilities Maintenance when motor may need additional work such as bearings, alignments, or cleaned-dippedbaked to prevent motor failure.

All flow meters and instrumentation shall be calibrated annually.

SCADA system radio shall be aligned and all connections inspected and repaired as necessary.

All vaults shall be checked for structure defects, cleanliness, pumped if necessary, and reviewed for confine space classification and entry procedures.

Every 2 Years:

All boosters are to be pump tested for efficiency, if they are in an active status.

Reservoirs with a capacity below 2 million gallon are to be drained, cleaned and inspected for structural changes, inlet outlet piping, and floor joints.

Every 5 Years:

Reservoirs with a capacity above 2 million gallon are to be drained, cleaned and inspected for structural changes, inlet outlet piping, and floor joints.

As-Needed Notes:

Anytime a GAC vessel is taken out of service for repairs, maintenance, or offline for an extended period oftime, it will be inspected, disinfected (treated with caustic soda solution if required), flushed, and tested for bacteriological contamination. Wells and pipelines going to the vessels will be disinfected and bacteriological testing conducted and verified prior to being brought into service.

Note: Following the above procedure, SBMWD staff is responsible to ensure completion of the task by noting the task in the treatment plant shutdown and/or start-up form(s).

23. Methods of Determining PCE/TCE Removed:

The SBMWD tests PCE/TCE concentration in treated effluent weekly and PCE/TCE concentration in combined influent quarterly. The SBMWD assumes an average concentration ofPCE/TCE in the combined influent over the quarter.

The pounds of PCE/TCE removed each quarter will be calculated as follows:

lbs PCE/TCE =Mil Gal x 8.34 x ug/L)/1000)

A sample of a pounds removed spread sheet with calculations is in (Attachment 18 - Monthly Treatment Summary)
