1.0 lnuoducuon ____________________________ ~~-------
This report presents groundwater data collected from the Market Place Landfill (Site). The data were collected during Solid Waste Assessment Test (SWAT) sampling conducted in 1988 and 1989, as well as the two rounds of semiannual sampling conducted in December 1994 and September 1995. The SWAT groundwater data and the recent semiannual groundwater data are combined to simplify comparison of water quality and chemistry from the recent past to the present.

1. 1 Project Background
The Los Angeles Regional Water Quality Control Board (RWQCB) reviewed the site SWAT addendum report (IT, 1991) and prepared a review letter dated September 19, 1994 (RWQCB, 1994). The review letter indicated that the SWAT monitoring network, although capable of detecting waste constituents in the groundwater, has not adequately demonstrated that the subject disposal site is not the source of certain compounds detected in groundwater monitoring wells downgradient of the disposal site.

On behalf of Bixby Ranch Company, IT responded to the review letter and recommended that the site groundwater monitoring wells be sampled twice over the next 12 month period and that the samples be tested for dissolved lead and nickel in accordance with EPA Method 6010, for pesticides in accordance with EPA Method 608, .and for leachate indicators. The RWQCB [l agreed that semiannual sampling would be adequate but that the samples must be tested during the first round for the following analytes:

• General groundwater chemistry
• Selected metals
• Purgeable organic halocarbons and aromatics
• Pesticides and polychlorinated biphenyls (PCBs).

Following review of analytical data from the first semiannual sampling, an agreement was reached with the RWQCB on August 29, 1995 to limit the analytical testing for the second semiannual sampling and only include purgeable organic halocarbons and aromatics, pesticides and polychlorinated biphenyls (PCBs), and general groundwater chemistry in the analytical IR\1-96\BIXBY\021 h2 1

program.

The following sections discuss the site health and safety program, field activities, groundwater monitoring results, the results of analytical testing, and conclusions.

2. 0 Site Health and Safety Plan ____________ _
IT is committed to provide a safe and healthful work environment for all its employees. In accordance with the Code of Federal Regulations, Title 29, Section 1910.120 and the California Code of Regulations, Section 5192, a site-specific health and safety plan was prepared for all field activities. The plan addresses known and potential site hazards, protective measures to minimize worker exposure, emergency routes, and other considerations related to the safety of personnel on site. The health and safety plan was reviewed and signed by all appropriate site personnel, and was enforced by the IT-qualified site safety officer.

3.0 Field Activities __________________ _

3. 1 Groundwater Sampling
[] On September 7, 1995, IT personnel purged and sampled the five groundwater monitoring wells at the site. Details of the sampling event are discussed in the following sections. u
u
r I
l_ j

3.1.1 Groundwater Level Monitoring
Prior to purging and sampling the wells, the depth from the top of casing to water in the monitoring wells was measured using a electronic water level meter. Water level data and well casing elevation survey data were used to calculate groundwater elevations relative to mean sea level. Water level measurements and well elevation survey data are summarized in Table 1.

3. 1. 2 Groundwater Purging and Sampling
The monitoring wells were purged of approximately three casing volumes of water using a Grundfos Ready-Flow II, 2-inch submersible pump connected to 0.5-inch diameter high density polyethylene (HDPE) tubing. Groundwater purged from the wells was temporarily IR\1-96\BIXBY\0211 r2 2

stored on-site in 55-gallon steel drums pending analytical results. The drums were subsequently sent to a waste disposal recycling facility. Field measurements of pH, electrical conductivity, and temperature were recorded for each casing volume of water removed. Well purging continued until three casing volumes had been purged and the aforementioned parameters stabilized.

Following purging, the water levels in each well were allowed to recover to approximately 80 percent of the pre-purge level. At this time, the submersible pump was reactivated and the pump controller adjusted to allow a low but continuous flow of water. Groundwater samples were collected directly from the pump discharge tubing into appropriate containers. New tubing was used for each well to prevent the risk of cross-contamination between wells.

4.0 Analytical Program _______________ _
\ Groundwater samples were analyzed in accordance with the following Environmental Protection Agency (EPA) Methods, per agreement with the RWQCB:

IR\1-96\BIXBY\0211r2
•
•
Volatile purgeable halocarbons and aromatics - Method 8240 Pesticides/PCBs - Method 8080
• Biochemical oxygen demand (BOD)- Method 405.1

5.0 Results---------------------

5.1 Groundwater Levels and Flow Direction
Groundwater levels were observed to be approximately 0.95-feet higher in most wells compared to those measured during the December 1994 semiannual monitoring (Table 1). The groundwater flow direction for the September 1995 monitoring is toward the north-northeast and consistent with the flow directions observed during previous monitoring events (Figures 3 through 8).

5. 2 Laboratory Analyses
The analytical results for this monitoring are summarized in Tables 2 through 5. The laboratory report, analyses request and chain-of-custody record are provided in Appendix A.

6.0Discussion ______________________ __
Groundwater elevation data from six quarters of measurements at the Market Place Landfill have consistently indicated that the groundwater flow is to the east and northeast. With detected concentrations ofbenzene at 84 micrograms per liter (ug/1) in MP-3 and 8.9 ug/1 at MP-1, we feel that the data indicate that the source of the benzene contamination is from the direction of higher concentration upgradient ofwell MP-3.

Upgradient of well MP-3, approximately 150 feet across Pacific Coast Highway is the location of a former Chevron Seal Beach Gas Plant property which operated from 1929 to the mid-1970's. A gas compression booster plant continued in operation there untill985. Soil with BTEX and TPH contamination was excavated at the property, bioremediated, and replaced in the excavation pits, thereby eliminating the source of the contaminant. The total volume of soil excavated included 56,730 cubic yards, ofwhich 23,420 cu yds was selected for bioremediation. The groundwater, however was left untreated since it was considered nonpotable due to its saline and brine content.

A closure report (by Levine-Fricke, dated June 21, 1994) for the former Chevron Seal Beach Gas Plant property, indicates benzene was detected at 414 and 770 micrograms per liter in groundwater taken from a groundwater monitoring well along Pacific Coast Highway (upgradient IR\l-96\BIXBY\021lr2 4

of the Market Place property). In a study by Harding Lawson Associates (1987) of the former gas plant property, data indicated a benzene concentration of 621 ug/1 was detected in groundwater from an on-site monitoring well, and soil sample data indicated a BTEX concentration of2,500 micrograms per kilogram (ug/kg) benzene, 9,500 ug/1 toluene, 108,000 ug/1 ethylbenzene, and 162,000 ug/kg oftotal xylenes. Hydraulic gradient data from the central portion of the former gas plant property, where the benzene-contaminated well was located, was calculated to be to be north to northeast at 0.0027 :ft/:ft supporting the findings of this study.

Analytical results from the 1994 Levine-Fricke closure report for the former gas plant property indicate that, of the four wells sampled and analyzed, the sample with elevated benzene concentrations (414 and 770 micrograms per liter) also had significantly higher (nearly 100 percent higher) chloride concentrations (71,000 milligrams per liter) and Total Dissolved Solids (120,000 milligrams per liter) than other samples from the study. This suggests the groundwater from that well did not mix with fresh water, was fairly stagnant, and had a seawater source supporting a directional flow toward the Market Place Landfill.

7.0 Conclusions ___________________ _
Analytical results contained in this report indicate that pesticides were not detected in groundwater from any of the monitoring wells during the two rounds of semiannual sampling.

Groundwater from up gradient well MP-3 did however show a concentration of dissolved benzene at 84 micrograms per liter (ug/1), an increase from the 14 ug/1 detected during the first semiannual sampling round. However, the benzene concentration from this well has generally decreased from a high of 800 ug/1 detected in October of 1988 to its current level of 84 ug/1 detected in September 1995. which we believe is consistent with the elimination of the source of contamination at its off-site origin which is upgradient.

Groundwater samples from downgradient well MP-1 showed detections of several purgeable \. halocarbons and aromatics. The concentrations were higher than what was detected during the first round of semiannual sampling. However, it should be noted that all of the concentrations I ' were below Maximum Contaminant Levels (MCL's) for drinking water, with exception of ! benzene and vinyl chloride. The compounds detected included: benzene, 1,2-, 1,3-, and 1,4- Dichlorobenzene, trans-1,2-Dichloroethene, and vinyl chloride. Chlorobenzene was detected IR\l-96\BIXBY\021lr2 5

at 1.2 ug/1 during the first semiannual sampling, as well as ethylbenzene and total xylenes at

2.0 and 1.7 ug/1, respectively. The concentrations of these compounds in .the samples from MP-1 were below the MCL's for drinking water. None of these compounds were detected in the well during the initial four quarters of SWAT monitorings. Since the groundwater beneath the site is saline and nonpotable, the maximum allowable contaminant levels for the above contaminants is likely to be higher than that established for drinking water.

Following a review of sites with previous or current environmental problems in proximity with the Market Place Landfill, and the nature of the dissolved contaminants found in the upgradient and downgradient wells, IT believes that the contamination is from an off-site source upgradient from the Market Place Landfill. The potential upgradient source, located approximately 150 feet across Pacific Coast Highway, is the location of a former Chevron Seal Beach Gas Plant property which operated from 1929 to the mid-1970's. A gas compression booster plant continued in operation there until 1985. Soil with BTEX and TPH contamination was excavated at the property, bioremediated, and replaced in the excavation pits thus eliminating the source of the contaminant. As groundwater with dissolved contaminants migrates from the suspected upgradient site across the Market Place Landfill and mixes with waters beneath the landfill, the landfill materials breakdown and release organic compounds (i.e. petroleum hydrocarbons) which could explain the dissolved contaminants which were detected in downgradient well MP-1. In addition, the fact that concentrations of benzene are diminishing the further away from the source one goes would also point toward the former gas plant property as the origin of the contaminant. The former gas plant received closure by the RWQCB on September 22, 1994 without any request for groundwater remediation based upon the nonpotability of the groundwater. Based. on all the data collected at the Market Place Landfill and the nonpotability of the underlying groundwater we believe no further activities are required at this site and invoke your concurrence on this matter.

SWAT REPORT APPROVAL - MARKET PLACE SANITARY LANDFILL (CITY DUMP SALVAGE NO. 2), LONG BEACH (FILE NO. 60-89)
Reference is made to our letter dated April 20, 1994, which transmitted our findings and our conditional approval of your June 1989 Preliminary SWAT Report and January 1991 Addendum Report. Approval was given contingent upon two additional semi-annual ground water sampling events being performed and analyzed for volatile organic compounds (VOCs}, base/neutral/acidextractable compounds (BNAs}. pesticides, heavy metals, and general minerals. Additional monitoring was required because existing data had not adequately demonstrated that the landfill is not a source of the lead, nickel, and pesticides detected in downgradient monitoring wells.

Results of the additional ground water sampling events performed in December 1994 and September 1995 are as follows:

GENERAL WASTE DISCHARGE REQUIREMENTS FOR POSTCLOSURE MAINTENANCE - MARKET PLACE LANDFILL, LONG BEACH (FILE NO. 60-089, Cl-2767, GEOTRACKER GLOBAL ID. T10000004438)
Dear Mr. Zak:

The California Regional Water Quality Control Board, Los Angeles Region (Regional Board), is in receipt of a Report of Waste Discharge (ROWD, Form 200), dated October 10, 2015, submitted by Lyon Housing (Pumpkin Patch) XLV, LLC (Discharger). The ROWD applies for regulatory supervision from the Regional Board for the environmental investigtion associated with the proposed development of a property at 7001 East Pacific Coast Highway, Long Beach, California (Figure 1 ), that includes the inactive Market Place Landfill, also known as the City Dump Salvage No. 2 Landfill (Landfill).

Background
In 1960, the City Dump and Salvage, Inc. (Operator) leased the property from the Bixby Ranch Company to develop a municipal waste landfill. The County of Los Angeles, Industrial Waste Division, permitted waste acceptance on the eastern half of the property that complied with the following criteria:

Non-water soluble, non-decomposable inert solids;
Ordinary household and commercial refuse, including decomposable organic refuse and scrap metal;
Garbage and market refuse.

The disposal of liquids, semi-liquids, and hazardous classified waste was not permitted. The Landfill was operated to its permitted capacity from mid-1960 to early 1961 .

Currently, there is an active oil field pumping unit and surface and subsurface pipelines for oil delivery on the eastern portion of the property. A conceptual plan for proposed redevelopment of the property that will expand oil field operations, including well heads, storage tanks, and office space is shown on Figure 2. The Discharger proposes to develop the referenced 7.08- acre property that consists of three parcels (Figure 3) identified as Assessor's Parcel Numbers (APNs) 7237-020-043 [Parcel4], APN 7237-020-044 [Parcel 5], and APN 7237-020-045 [Parcel 6]. Currently, the westernmost parcel of the subject property, Parcel 4 (4.34 acres), consists of open space that is used for seasonal pumpkin and Christmas tree sales. Active oil field Chi\·-:tt:l..\ s HIN(it:h CHAIR I SAMUEL UNGER EXECU TIVE OFFICER 3?0 Wrr.t 4th St , Su1te 200, Lo:o; Anqnto~. CA 90013 I www watorboards.crt gov/lostlngeiPs Mr. Peter D. Zak - 2 - November 25, 2015
Lyon Housing (Pumpkin Patch) XLV, LLC
operations are conducted on the eastern parcels, Parcel 5 (1.36 acres) and Parcel 6 (1.38 acres).

The Discharger completed a Phase I Environmental Site Assessment (ESA) in May 2011 , and a follow-up Phase II ESA soil and groundwater assessment in 2012. Results of the ESAs recognized the potential for soil and groundwater contamination associated with the historic landfilling on the property. In July 2015, the Discharger updated the ESA investigations and concluded that determining the vertical and horizontal extent of hydrocarbons, volatile organic compounds (VOCs), polynuclear aromatic hydrocarbons (PNAs), mercury, and polychlorinated biphenyl (PCBs) associated with the former Landfill was warranted to support the proposed redevelopment project. The Discharger proposes characterization of site conditions that includes:
• Advancing five soil borings with a hollow-stem auger drill rig to identify the upper contamination limits as well the vertical and lateral extent of chemicals of potential concern (COPCs) associated with the Landfill;
• Collecting soil samples to analyze for COPCs;
• Constructing five groundwater monitoring wells in the area of the Landfill; • Conducting a groundwater monitoring program, for a minimum of one year, to establish potential COPCs contamination trends at the subject property.

Applicability for Postclosure Maintenance General WDRs
This Regional Board adopted Order No. R4-2002-022 (Order) on January 24, 2002, that includes general WDRs for the postclosure maintenance of closed, abandoned, or inactive (CAl) landfills as defined in section 20164 of title 27 of the California Code of Regulations (27 CCR).

The Order is specifically targeted towards CAl landfills undergoing redevelopment or modifications in end use. The Landfill is classified as a CAl unit because it ceased operations prior to the November 27, 1984, effective date of 27 CCR regulations. The Landfill meets enrollment criteria of the Order because of the potential release of pollutants to the environment during and after the proposed development.

Regional Board staff has completed review of the ROWD and determined that the Landfill is appropriate to be regulated under the Order. Individual WDRs for the proposed project are therefore not required. Pursuant to Requirement A of the Order, Monitoring and Reporting Program (MRP) No. Cl-8372 referenced in the Order is hereby replaced with MRP No. Cl-2767 that is specifically prescribed for the Landfill. Enclosed are WDRs for the Landfill, comprising:

1. General Waste Discharge Requirements (Order No. R4-2002-022);

2. Monitoring and Reporting Program (CI-2767);
3 Standard Provisions.

Conditions and Amendments
As provided under Requirement A.2.b (Page 7) of the Order, the following conditions and amendments are applied to the coverage of the Landfill under the general WDRs:

Mr. Peter D. Zak - 3 - November 25, 2015
Lyon Housing (Pumpkin Patch) XLV, LLC

1. The characterization of existing Landfill conditions is deemed to meet the requirements of the general WDRs. The Soil and Groundwate·r Assessment Work Plan, dated July 2015, is hereby approved. Any modification of assessment work plan must be reported to Regional Board staff. Substantial changes, as determined by Regional Board staff, must be approved by the Regional Board Executive Officer before being implemented;

2. The postclosure groundwater monitoring program proposed in the Plan is deemed to update of the Solid Waste Assessment Test (SWAT), required in Section C of the Order, which was completed for the Landfill in January 30, 1996. The submittal of a separate SWAT proposal for the Landfill is therefore not required;

3. The proposed postclosure groundwater monitoring network, which includes groundwater monitoring wells MW-1 through MW-6 (Figure 2), shall be installed within 90 days following enrollment under the general Order ;

4. Groundwater monitoring pursuant to MRP Cl-8372 shall start immediately following the installation of groundwater monitoring wells and shall be continued until the Regional Board Executive Office determines that such monitoring may be discontinued;

5. The Discharger must comply with any gas migration control or monitoring requirements prescribed by the County of Los Angeles Environmental Health Division; and

6. Enrollment of the project under the general Order does not relieve the Discharger from requirements of other oversight agency(ies) for land use or oil field development, operations, or remediation, including the City of Long Beach, the California Division of Oil, Gas, and Geothermal Resources, and the California Coastal Commission.

If you have· any questions regarding this matter, please contact Dr: Enrique Casas, Project Manager, at (213) 620-2299.

requests for implementing groundwater monito1ing and post-closure maintenance requirements for these closed, abandoned, or inactive l<mdfills.

4. Many of the closed, abandoned and inactive landfills in the Los Angeles Region contain a variety of nonhazardous materials, including municipal, agricultural, and/or petroleum wastes. However, these facilities also received waste dudng a time period when recordkeeping and other environmental requirements were not as stringent. The facilities sometimes received a variety of waste materials commingled with more conunon, inert and or nonhazardous wastes. As a result, the groundwater monitming requirements specified by this Order and its attaclunents are intended to screen and sample for a wide vruiety of wastes (including pesticides and solvents) that may have been disposed in the facilities subject to this Order.

5. Pursuant to Title 27 section 20080(g), persons responsible for discharges at landfills that are closed, abandoned, or inactive may be required to develop and implement a monitoring program. If water quality impairment is found, such persons may be required to develop and implement a corrective action program based on the provisions of Chapter J, Subchapter 3, Article 1 (Water Quality Monitoring and Respo11st: Pro!:,•ntms for Solid Waste fvlanagement Units), of Title 27 section 20380 et seq.

6. The Regional Board may require formal closure of a landfill in accordance with Title '27 Chapter 3, Subchapter 5, Articles 1 (conunenci ng with section 20950) and 4 (commencing with section 21430) under the following conditions listed below, consistem •vith Title 27 section 22190:
a. when there is a proposed site development or land use change that jeopardizes the integrity of the existing cover;
b. when water quality impairment is found, as part of a groundwater monitoring program; or
c. when nuisance conditions exist that wanant such activity.

7. Pursuant to Ca lifornia Water Code (CWC), section 13263, this Regional Board issues WDRs for post-closure maintemmce of inactive landfills. In accordance with CWC section : 3263( d) the Regional Board may presclibe requirements alrhough no RepO!i of Waste Discharge (ROWD) has been filed.

8. The State Board has developed a fee rating system (Title 23, section 2200) for WDRs that considers a discharge's threat to water quality and complexity. The two-dimensional 2 C t' \TERAL \\ .\.STli DlSCIJ \ RGE REQUlREl\JE. TS

rating system requ ires the Regional Board to assign each discharge a category of threat to water qnality bet\:>.'een "1" (most threateni ng) and ''3" (least threatening) based on certain factors. S-imilarly, the:! Regional Board must assign each discharge a complexity rating between ·'A" (most complex) and "C" (least complex). As discussed bdow, thl' Order coYers 1\\ u classes of discharge!: those with a fcc rating of 1-13 or 3-C. ~1 . C\VC st:clion 132"''3 requires thl! State Board to de\·elop a ranked list of all kJlO\\ n landiil:s throughou :he state on the basis of the threat to water quality Sc:...tion 1·11- 3 requires the operator of each solid \\'as:e disposal site on the ranked hst ~o conduc.t a:1d submit to the appropnatc Regional Board the results of a Solid Waste Assessment Tes1 (SWAT) report to determine if the site is leaking hazardous waste. llJ. S \\' A"l r~.:po rt s indicated that lnnd (ills which contain decomposable waste ha,·c llaked hazardous waste to gToundwater. Volatile org<mie constituents in groundwater near tbc:
inactive landfills may have occurred thJOugh landfill gas migration. These impacts to groundwater adversdy affect beneficial uses and could cause a long-t,..nn loss of a designated beneficial use.
l l. Because of the potential impact to groundwawr quality, from leaking inncuve landtills, the Regional Board considers such landfills as a category "1" threat to \\'ater qualit). ;n accordance with [itlc 23, secuun 2200. As fo1mer C'lass II or C'Ltss m \\aqe management facilities, the in.tcuve lar.dfills subject to tlu s Order arc ass1gr.ec.. a complexity ranking of categor) '"B".

12. Landfills t.hat do not contain decomposable waste such as those that were operated by open burning of refuse may also impact water quality. The residual waste material may contain soluble constlluents which are leachable to \.\'Uters of the state under actthc conditions. Potenti.1l water quahty impacts from these land[i]ls could result n·om eroswn during the rainy season, if \.\'aslc is exposed and is not contained onsiLL:. Surface wtttt:r quali ty objectives may be excet:dcd in cases of extreme eroswu of these land rill surfat:L'S.

For pu rp o~es of this Order, the R~.:gional Board considers landtllls a categor) ·•J" tlu·cat to water quality \vhen potential discharges could degrade water quali;:! wi thout ,·iolat ng water quality objectives or cause a minor impairment of designated beneficwl uses. "I he '·complexity" rating is a category "C" for discharges that must comply with be:,t manugemcnt practices such as erosion control measures.
! 3. The rssuance o-:" tillS Order est.tbhshing general WDRs is consistent\\ irh this Re~·ion.tl Board· s goal to plO\ tdc wale:· resources protection, enhancement. and restoratton. whik balancing econom:~.- and enYironmcn•al impacts as stated :n the Srratt!g1c Plcm or ·be.

Water Resources Control Board rmd the Regional Boards, and in conformance vvi th the Porter-Cologne Water Quality Control Act (CWC, section 13000, ct seq.). 14 . The issuance of this Order may supersede existing site-specific orders that were issued by this Regional Board to landfills that are in post-closure maintenance.

15. The adoption of general WDRs for inactive landfills for post-closure maintenance would assist in:
a. Protecting the groundwaters and smface waters of the state from pollution or contamination;
b. Simplifying and expediting the application process for WDRs by dischargers; and c. Reducing time expended by Regional Board staff on preparing and considering individua l WDRs for each project.

I G. The Regional Board has determined that the issuance of general V.,TDRs for post-closure maintenance of inactive, nonhazardous waste landfills is appropriate. The classes of facilities are similar in nature, present similar thl'eats to water resources, can be snnilarl y managed, and lend themselves to general requirements for tbe entire class of facilities covered by this Order.

17. The Regional Board adopted a revised Water Quality Control P lan for the Los Angeles Region (Basin Plan) on June 13, 1994. The Basin Plan contains beneficial uses (municipal and domestic supply, agricultural supply, industrial process supply, indusnial service supply, groundwater recharge, and freshwater replenishment) aJld water quality objectives for groundwater in the Los Angeles Region. The requirements in this Order, as they arc met, will be in confo rmance with the goals of the Basin Plan.

18. Inactive landfills are existing facilities and as such are exempt from the provisions of the Califomia Environmental Quality Act in accordance with Title 14, California Code of Regul ations, section 15301.

19. Tbe Regional Board, in establishing the requirements contained herem, considers factors tdcn~ified in ewe section l3263(a) inducting, but not limited to the following:

4. The SWAT Program shall focus on groundwater monitoring. However, in cases where there was an apparent threat to smface water quality, surface water monit01ing points shall also be established, and when approved by the Executive Offtcer, shall be monitored by the discharger in conformance with an approved monitoring plan.

5. Vadose zone monitming shall be implemented during the SWAT program.

However, the Ret,rional Board's Executive Officer may waive this requirement ror sites where the waste is very close to or present in groundwater; that is, where little or no vadose zone exists, and where it was assumed that the groundvvater analysis will show any leakage.

6. In cases where a site is already being addressed through another program or action by the Regional Board, the Regional Board's Executive Officer may consider reports submitted for the other program or action to be equivalent to a SWAT report. Examples include submittals of Hydrogeological Assessment Reports (HARs) fo r compliance with the Toxic Pit Cleru1Up Act, reports prepared in response to a Cleanup and Abatement Order, or monitoring under the core regulatory waste discharge requirement program for waste discharges to land (Land Disposal).

Groundwater Monitoring Program

7. The discharger shall use the constituents listed in Monitoting and Reporting Program No. CI-8372 and revisions thereto, as "monitoring parameters" These monitoring parameters are a short lisL of constituents and parameters used shall be used for the majority of monitoring activity and are subj eel to the most appropriate statistical or non-statistical tests under the attached Monitoring and Reporting Program No. CI-8372 and any revised monitori ng and reporting program approved by the Regional Boru·d's Executive Officer.

8. The discharger shall implement the attached Monitming and Reporting Program No. Cl-8372 and revisions thereto in order to detect, at the earliest opportunity, any unauthorized discha1ge of waste constituents from the landfill or any umeasonable impairment of beneficial uses associated with (caused by) discharges of waste to the landfill.

Re: First Semiannual Groundwater Monitoring Report
October 2015 to March 2016
Pumpkin Patch – Inactive Landfill Post-Closure Maintenance Monitoring and Reporting Program No. CI-2767 (File No. 60-089) Long Beach, California
Dear Dr. Casas:

Advanced Environmental Concepts, Inc. (AEC) is pleased to present this First Semiannual Groundwater Monitoring Report for the Pumpkin Patch property also known as the Market Place Landfill and City Dump and Salvage No. 2 Landfill in Long Beach, California (Figure 1). This report has been prepared in accordance with the General Order No. R4-2002-022 for post closure maintenance of closed, inactive, or abandoned landfills.

AEC submitted a Soil and Groundwater Assessment Work Plan dated July 2015 to Dr. Enrique Casas, Los Angeles Regional Water Quality Control Board (LARWQCB) for the installation of groundwater monitoring wells at the site. The Work Plan was approved by the LARWQCB on November 25, 2015.

QUARTERLY SITE INSPECTIONS
An inspection of the site was performed on March 29, 2016 by Mr. Jonathan Buck, Principal Geologist of AEC.

The subject property consists of three Parcels (Parcel 4, Parcel 5 and Parcel 6), legally identified by Assessor’s Parcel Numbers (APNs) 7237-020-043, -044, and -045 and is within a portion of the Northwest Quarter of Section 11; Township 5 South, Range 12 West, of the San Bernardino Base & Meridian System.

Currently, the western two-thirds of the subject property, identified as Parcel 4 (approximately 4.34 gross acres), consists of perimeter-fenced level graded open ground that is used for seasonal pumpkin and Christmas tree sales during the fall and winter months. Access is from Studebaker Road through a swing gate attached to the chain link fence. Studebaker Road and an asphalt-paved parking lot associated with The Market Place commercial development form the north boundary, the San Gabriel River forms the south boundary, Pacific Coast Highway forms the west boundary, and the Seal Beach Oil Field forms the east boundary. Along the east boundary of the Pumpkin Patch portion of the site is an area secured with temporary fencing where trailers, storage containers and various equipment is stored; these items are used for the seasonal pumpkin and Christmas tree sales. AEC additionally identified a groundwater monitoring well at the southwest corner of the subject property (MW-1) that was a part of a prior onsite investigation; AEC also observed several offsite monitoring wells along the south property boundary that are installed in the asphaltpaved bike path adjacent to the San Gabriel River channel. A shallow drainage swale was also observed along the south boundary adjacent to the San Gabriel River channel that drains seasonal precipitation from the central portion of the site.

The eastern one-third of the subject property consists of Parcel 5 (1.36 gross acres) and Parcel 6 (1.38 gross acres). These two parcels are bisected by a hill slope approximately 15-feet in elevation that trends northsouth. The eastern half of Parcels 5 and 6 are improved with an active oil field “horse-head” type pumping unit and surface and subsurface pipelines for oil delivery. The oil field infrastructure is on a lease basis with the property owners.

1.0 INTRODUCTION
Mr. Peter Zak, representative for Beach Oil Minerals Partners, has authorized Advanced Environmental Concepts, Inc. (AEC) to prepare this soil and groundwater assessment report which describes and evaluates the vertical and lateral extent of Total Petroleum Hydrocarbons (TPH), Volatile Organic Compounds (VOCs), Poly-Nuclear Aromatics (PNAs), Mercury, and Polychlorinated Biphenyls (PCBs) associated with the former landfill at the Pumpkin Patch Property, 7001 East Pacific Coast Highway, Long Beach, California (Figure 1). The subject site is currently undeveloped, with the exception of oil field infrastructure within the eastern one-third portion of the property and this eastern portion of the property has never been associated with the former landfill operation. The western two-thirds portion of the site extends from Pacific Coast Highway to the oil field related property; is relatively level-graded; and has been consistently used for seasonal sales of pumpkins and Christmas trees. Historical aerial photographs and prior reports indicate that the central-eastern portion of the western two-thirds of the subject property was used as a municipal landfill during 1960-1961 identified as the City Dump & Salvage Landfill #2. The waste accepted at the facility was reportedly composed of the following: non-water soluble and non-decomposable inert solids; ordinary household and commercial refuse, decomposable organic refuse, scrap metal, as well as garbage and market refuse (IT, 1987). The disposal of liquids, semi-liquids, and hazardous-classified waste was not permitted. The subject property is in planning stages for development as a land-based platform for a directional oil well drilling operation (Figure 2a and 2b). The regulatory contact for this project is Dr. Enrique Casas of the Los Angeles Regional Water Quality Control Board (RWQCB).

1.1 Purpose and Rationale
The soil and groundwater assessment program described in the RWQCB-approved work plan has the following objective:
• Evaluate the vertical and horizontal extent of TPH, VOCs, PNAs, Mercury, and PCBs associated with the former City Dump & Salvage Landfill #2 that operated at the Pumpkin Patch Property during 1960-1961. Five permanent groundwater monitoring wells have been installed to assess groundwater quality within and proximal to the former landfill trench and the wells were sampled approximately 24 hours following installation and will be sampled on a quarterly basis for a minimum 1 year period to establish potential contamination trends at the subject property.

1.2 Scope of Work
AEC performed the following scope of work for the installation of the five groundwater monitoring wells:

1. Locating underground utilities using Client records and Underground Service Alert (USA);

2. Advanced five soil borings with a hollow-stem auger drill rig to identify the upper contamination limits as well the vertical and lateral extent of Chemicals of Potential Concern (COPCs) including TPH, VOCs, PNAs, Mercury, and PCBs associated with the former landfill;

3. Collected soil samples using a split-spoon sampler lined with stainless steel sleeves at intervals of 5-feet; soil samples were analyzed for Total Petroleum Hydrocarbons as carbon chain (TPH-cc), Volatile Organic Compounds (VOCs), Poly-nuclear Aromatics (PNAs), Polychlorinated Biphenyls (PCBs), and Title 22 Metals;

4. Installed five permanent groundwater monitoring wells to approximately 34-feet below ground surface (bgs). The wells were completed using 2-inch diameter Schedule 40 PVC blank connected to 20-feet of 0.010-inch screen with a filter pack of #2/12 Monterey sand to one foot above the screened interval. An approximate 3-5 foot hydrated bentonite seal was placed above the sand pack followed by a cement-bentonite slurry to grade. The top of the well casing is protected by traffic-rated flush-mounted well boxes;

5. Following completion of the well installation the wells were developed using a submersible pump 1 day following well completion. The water obtained during development was placed in 55-gallon drums pending offsite disposal on an asneeded basis;

6. Following well purging the groundwater wells were sampled. Groundwater samples were analyzed for Total Petroleum Hydrocarbons as carbon chain (TPH-cc), Volatile Organic Compounds (VOCs), Poly-Nuclear Aromatics (PNAs), Polychlorinated Biphenyls (PCBs), and Title 22 Metals. In addition, the water was analyzed for chloride, sulfate and Total Dissolved Solids (TDS);

7. Prepare a final report detailing the results of the soil and groundwater investigation which will include drilling and sampling methods, analytical results, conclusions, and recommendations.

2.0 BACKGROUND
The subject property consists of three Parcels (Parcel 4, Parcel 5 and Parcel 6), legally identified as Assessor’s Parcel Numbers (APNs) 7237-020-043, -044, and -045 and is within a portion of the Northwest Quarter of Section 11; Township 5 South, Range 12 West, of the San Bernardino Base & Meridian System.

Currently, the western two-thirds of the subject property, identified as Parcel 4, consists of perimeterfenced level graded open ground that is used for seasonal pumpkin and Christmas tree sales during the fall and winter months. Access is from Studebaker Road through a swing gate attached to the chain link fence. Studebaker Road and an asphalt-paved parking lot associated with The Market Place commercial development form the north boundary, the San Gabriel River forms the south boundary, Pacific Coast Highway forms the west boundary, and the Seal Beach Oil Field forms the east boundary. Wood, paper and glass landfill debris is visible at the surface along the south boundary of the site. Also, along the east boundary of the Pumpkin Patch portion of the site is a fenced compound where trailers, storage containers and various equipment is stored that are used for the seasonal pumpkin and Christmas tree sales. AEC additionally identified a groundwater monitoring well at the southwest corner of the subject property.

The eastern one-third of the subject property consists of Parcel 5 and Parcel 6. These two parcels are bisected by a hill slope approximately 15-feet in elevation that trends north-south. The eastern half of Parcels 5 and 6 are improved with an active oil field “horse-head” type pumping unit and surface and subsurface pipelines for oil delivery. The oil field infrastructure is on a lease basis with the property owners.

The subject property was leased from the Bixby Ranch Company in 1960 by City Dump and Salvage, Inc. of Long Beach, California for the creation of the City Dump and Salvage Landfill #2. AEC has reviewed a “Final Report, Assessment of the Bixby Ranch Company Sanitary Landfill for the Presence of Hazardous Substances”, IT Corporation, June 30, 1987 and obtained the historical information regarding the landfill.

During September 1960, City Dump and Salvage received a permit from the County of Los Angeles, Industrial Waste Division, to accept wastes in the eastern half of the site at a minimum of 300-feet from Pacific Coast Highway.

Soil and Groundwater Assessment Advanced Environmental Concepts, Inc. 3 • ENVIRONMENTAL CONCEPTS WITH DESIGN IN MIND •
220 E. TRUXTUN AVENUE BAKERSFIELD, CA 93305 661/395-1646 FAX 661/395-1616 City Dump and Salvage commenced waste acceptance operations at the site in mid-1960 (prior to receiving an approved permit) and ceased operations in early 1961 after filling the landfill to its permitted capacity. Clients of the City Dump and Salvage landfill included the City of Long Beach, J & S Disposal Company (City of Lakewood), and the Veteran’s Administration Hospital.

The disposal permit allowed for the excavation and subsequent filling with refuse a trench that was excavated below the groundwater table in the eastern half of Parcel 4. Final cover of the landfill was completed by May 16, 1961. During March and April 1987, the IT Corporation (IT) drilled and sampled soil borings at the site to identify the varying depths of the refuse burial and to evaluate if there were hazardous concentrations of chemicals impacting soil and/or groundwater. The results of their sampling indicated that the landfill is typically rectangular-shaped, encompasses the eastern half of the property, and that the refuse in the central portion of the burial area extends to a depth of 30-feet below ground surface (bgs). The refuse in the landfill consists of newspaper, plastic, metal, wood, glass, plant debris, rubber tubes and tires, and green waste. IT also installed two groundwater monitoring wells at the site (MW-1 and MW-2A), and determined that groundwater is typically identified at 15-feet bgs, is primarily derived from sea water intrusion, and does not constitute a source of drinking water.

Soil samples collected from the borings were submitted for analysis as both composite and discrete. The results indicated total lead concentrations ranging between 3.3 mg/kg to 386 mg/kg. The current California Human Health Screening Level (CHHSL) for lead in residential-use soil is 80 mg/kg and in commercial/industrial-use soil is 320 mg/kg. In addition, there was a detection of Arochlor 1248 (PCB with 48% chlorine by weight) of 4.2 mg/kg and the residential-use CHHSL is 0.089 mg/kg and the commercial/industrial use is 0.3 mg/kg.

The analytical results for lead and PCBs obtained during the 1987 IT investigation did not exceed recommended action levels for that period. However, during the past 24 years, the acceptable concentrations for lead and PCB Arochlors have decreased dramatically. Therefore, it was previously recommended by AEC, that an updated subsurface soil and groundwater investigation be conducted within, and surrounding the landfill. It was recommended that selected soil and groundwater samples be analyzed for Total Petroleum Hydrocarbons as carbon chain (TPH-cc); Title 22 Metals, PCBs, Volatile and Semi-volatile Organic Compounds (VOCs and SVOCs), organo-phosphate pesticides and herbicides, and chlorinated pesticides and herbicides.

During 2012, AEC was contracted by Lyon Communities to investigate the current subsurface soil and groundwater conditions within the former landfill trench as well as outside the confines of the former landfill. Three cone-penetrometer (CPT) borings and four hollow-stem auger borings were performed onsite. AEC collected soil samples for laboratory analysis and also obtained “grab” groundwater samples from first encountered groundwater. Selected soil samples were analyzed for TPH-carbon chain (TPHcc), Volatile Organic Compounds (VOCs), Poly-nuclear Aromatics (PNAs), Polychlorinated Biphenyls (PCBs), and Title 22 Metals or Lead. The results of the soil analyses indicates that the area of environmental impact exceeding regulatory-derived “actionable” concentrations occurs within the confines of the former landfill trench and confirmed with the soil samples obtained from B-1. The analytes that commonly exceeded regulatory-driven “actionable” concentrations were the Poly-Nuclear Aromatics (PNAs) of which Naphthalene was the most common detection. Naphthalene is a common naturally occurring by-product of oil field production and is also a precursor to the anthropogenic formulation of other chemicals; therefore, would be expected to be identified within the confines of a former landfill from 1960 that is within the boundaries of an oil field that has been producing since the 1920s.

AEC subsequently performed an updated ESA for the subject property during July 2015 and recommended that permanent groundwater monitoring wells be installed at the subject property within and proximal to the former landfill and quarterly groundwater monitoring be implemented for a minimum 1 year period to define the upper contamination limits as well as vertical and horizontal extent of impacted groundwater at the subject property.

3.0 HYDROGEOLOGY

3.1 Topography
The site lies within the Coastal Plain of Los Angeles County. The Coastal Plain is primarily a featureless plain that slopes gently to the south and west, towards the Pacific Ocean. The Coastal Plain is bounded to the northwest by the Santa Monica Mountains; to the north and northeast by the Elysian, Repetto, Puente, Merced, and Coyote Hills; to the east by the Los Angeles – Orange County border; and to the south and west by the Pacific Ocean. Local topographic highs are dispersed throughout the Coastal Plain and are the surface expressions of subsurface deformation.

The most notable topographic highs in the area have evolved in response to interaction of the Los Angeles, Rio Hondo and San Gabriel Rivers with the Newport-Inglewood uplift. The surface expression of the Newport-Inglewood uplift is a northwest trending suite of low hills that separate the central portion of the Coastal Plain from the portion that flanks the Pacific Ocean. The Newport-Inglewood uplift is defined by the Beverly, Baldwin, Rosecrans, Dominguez, Signal, and Bixby Ranch Hills.

The subject site lies at an elevation of approximately 18 feet above mean sea level on a gently southwest sloping portion of the Coastal Plain. The San Gabriel River is located immediately southwest of the site, and flows into the adjacent Alamitos Bay and the Pacific Ocean.

3.2 Geology
This portion of South Long Beach/Seal Beach is on a coastal plain underlain by relatively recent sediments ranging in age from Quaternary deposits of the Pleistocene epoch (11,000 to 1,600,000 years) through the Holocene epoch (less than 11,000 years). The older sediments typically are shallow marine terrace deposits that have been uplifted by ongoing seismic movement and eroded to form the Bolsa Chica and Huntington Beach mesas. The mesas are bordered by younger (unconsolidated) alluvial soils that fill the gaps near Seal Beach, Bolsa Chica, and the Santa Ana River. The alluvial sediments are many hundreds of feet thick throughout the Seal Beach area. The Newport-Inglewood Fault Zone is visible on the ground surface as a series of northwest-trending elongated hills, including Signal Hill and the Dominguez Hills, extending from Newport Beach to Beverly Hills and is adjacent to the subject property.

This area of Long Beach is seismically active. The region is crossed by a network of major regional faults and minor local faults. This faulting and seismicity is dominated by the San Andreas Fault System, which separates two of the major tectonic plates that represent part of Earth’s continental and oceanic crust: the Pacific plate is west of the San Andreas Fault System; the North American plate is to the east. There are numerous faults in the general area that are categorized as active, potentially active, and inactive by the California Geological Survey. A fault is classified as active if it has either moved during the Holocene epoch (during the last 11,000 years) or is included in an Alquist-Priolo Earthquake Fault Zone. The Newport-Inglewood Fault Zone is an active right-lateral fault system consisting of a series of fault segments located mostly parallel to the coastline throughout the City of Long Beach. The Seal Beach fault trace is also active in the area of the subject property.

The shallow native soil beneath the subject property consists of silty sand to medium grained sand to approximately 25-feet below ground surface (bgs). The western two-thirds of the subject property has an average elevated of 18-feet above mean sea level (msl) and the eastern onethird has an average elevation of 5-feet msl. Groundwater associated with sea water intrusion has been identified between 15 to 20-feet bgs across the western portion of the subject property and is nearer to 10-feet bgs in the eastern portion. The depth to groundwater varies with tidal fluctuation. The east-central portion of the western two-thirds of the subject property has been Soil and Groundwater Assessment Advanced Environmental Concepts, Inc. 5 • ENVIRONMENTAL CONCEPTS WITH DESIGN IN MIND •
220 E. TRUXTUN AVENUE BAKERSFIELD, CA 93305 661/395-1646 FAX 661/395-1616 previously excavated into the water-bearing zone to an approximate depth of 32-feet bgs during 1960 and backfilled with layers of refuse and import fill associated with its use as a municipal landfill.

4.0 DRILLING AND SAMPLING
Advanced Environmental Concepts, Inc. proposed to advance five soil borings and install dedicated groundwater monitoring wells. The drilling and sampling of the five exploratory soil borings was accomplished using J & H Drilling.

4.1 Soil Sampling
The borings were advanced using a truck mounted CME-75 hollow-stem auger drill rig. Prior to and after drilling, the augers were steam cleaned to minimize any chance of affecting a potentially "clean" location.

Soil sampling was conducted during the installation of the groundwater monitoring wells using the hollow-stem auger drill rig by driving a California split-spoon sampler fitted with clean stainless steel sleeves into undisturbed soil. The sleeves were removed from the sample barrel and the bottom sleeve was sealed, placed in an ice chest, and recorded on a chain-of-custody for shipment to TestAmerica Laboratories for analysis. The soil in the middle sleeve was used for lithologic description and also for obtaining photoionization detector (PID) readings. Soil lithology described from the cuttings was recorded on the attached boring logs in accordance with the Unified Soils Classification System (USCS). Soil samples were able to be retrieved at intervals of 5-feet from all borings with the exception of AEC-1 which was advanced through the central portion of a former landfill trench. The trench was so full of debris and lacking in cohesive soil, therefore, a representative soil sample could not be obtained at 10’, 15’ and 20’ bgs.

4.2 Soil Sample Results
AEC collected soil samples and analyzed the soil for Chemicals of Potential Concern (COPCs) including TPH, VOCs, PNAs, Metals, and PCBs. The analytical results identified numerous detections of TPH as gasoline, diesel and oil along with VOCs in borings AEC-1 and AEC-2 which is to be expected since these two locations are within the former City Dump & Salvage #2 waste acceptance trench. Also, shallow soil collected from AEC-3 indicated 1,700 mg/kg of oilrange hydrocarbon and the soil sample exhibited a crude oil odor leading AEC to believe that the boring was in, or near the former oil well sump associated with oil well “Bixby A” 11. AEC-2-20’ was the only soil sample to exceed an Industrial ESL comparative standard and the analyte was diesel at 2,000 mg/kg (ESL of 1,100 mg/kg).

4.3 Well Installation
The five groundwater monitoring wells were installed to an approximate depth of 34-feet bgs and existing well (EW-1) had been drilled during April 1987 to a depth of 31.5-feet bgs. The five new wells consisted of 2-inch diameter, flush-threaded, Schedule 40 PVC with an end cap. The wells were installed through 8-inch diameter hollow-stem auger and the bottom 20-feet of casing consisted of 0.010-inch factory slotted liner. The sand pack was placed while removing the auger and the filter pack consisted of Number 2/12 Monterey sand which was methodically poured down the annulus. The filter pack was generally placed one foot above the screened interval and bentonite chips were poured on top of the sand and hydrated to form a seal. A neat cement/bentonite slurry was used to fill the annular space to grade level. Traffic rated flushmount protective boxes were installed and cemented. EW-1 consists of 4-inch diameter casing and the screened interval was placed between 31.5-feet to 6.5-feet bgs. The well locations were Soil and Groundwater Assessment Advanced Environmental Concepts, Inc. 6 • ENVIRONMENTAL CONCEPTS WITH DESIGN IN MIND •
220 E. TRUXTUN AVENUE BAKERSFIELD, CA 93305 661/395-1646 FAX 661/395-1616 surveyed to a known benchmark by Chris Nelson & Associates in accordance with GeoTracker requirements. The groundwater flow direction has been calculated at South 550 East with a gradient of 0.12’/foot. However, it is the opinion of AEC that the groundwater elevations are tidally influenced; therefore, AEC will return to the site and collect depth to water readings during a consecutive “high” and “low” tide event.

Following completion of the well installations, the wells were developed using a submersible pump. Approximately 3-5 casing volumes were removed from each well to achieve adequate development. Well development commenced approximately one day following well completion.

The water obtained during development was placed in 55-gallon drums which are currently stored at the Pumpkin Patch site.

4.4 Groundwater Sample Results
Following well development, the groundwater wells were sampled. The collected groundwater was transferred to 1 Liter Amber jars and 40 milliliter VOAs and analyzed for Total Petroleum Hydrocarbons as carbon chain (TPH-cc) by EPA Method 8015M; Volatile Organic Compounds (VOCs), including the full suite of oxygenates, by EPA Method 8260B; Title 22 Metals by EPA Methods 7471A/6010B; Polynuclear Aromatic Hydrocarbons (PAHs); PCBs by EPA Method 8081A; and water quality parameters of chloride, sulfate and Total Dissolved Solids (TDS). The analytical testing was conducted by Test America, a California-Certified Laboratory. The groundwater well samples that exhibited the most detections of the requested analytes were from wells AEC-1 and AEC-2; again, not a surprise since these two wells were completed within a former waste acceptance trench. The groundwater from well AEC-1 exhibited concentrations exceeding the comparative Industrial ESL standard for the VOCs 1,4-Dichlorobenzene, Benzene, Ethyl Benzene, Naphthalene, and TBA. AEC-1 also exhibited gasoline and diesel concentrations exceeding their respective ESLs. In addition, Aroclor-1242 and 1258 (PCB compounds) exceeded their respective ESL standard. Groundwater well AEC-5 and EW-1 did not exhibit any TPH, VOC, SVOC, and/or PCB detections; well EW-1-W has been an “existing well” onsite since April 1987. Analytical results from AEC-3 and AEC-4 exhibited trace to non-detectable concentrations of TPH and VOCs; non-detectable concentrations of SVOCs; and no detections of PCBs. The Chloride, Sulfate and Total Dissolved Solids concentrations from all six groundwater wells exceed their respective Secondary MCLs of 250 mg/L; 250 mg/L and 500 mg/L, respectively.

5.0 CONCLUSIONS
The analytical results for both soil and groundwater indicate the highest concentrations and greatest volume of detectable analytes are identified in groundwater wells AEC-1 and AEC-2. These two wells are positioned within the former boundary of the City Dump & Salvage #2 waste acceptance trench. AEC was unable to obtain representative soil samples from 10’, 15’ and 20’ bgs in AEC-1 because of the large volume of refuse and void space at the boring location. The cuttings from this boring included newspaper, wood, wire, metal fragments and glass. The soil and water from both AEC-1 and AEC-2 exhibited consistent black staining and discoloration and a strong hydrogen sulfide odor most likely caused from the decomposition of construction waste. Also, groundwater from AEC-1 and AEC-2 exhibited detectable concentrations of PCBs (Aroclor 1242 and 1248) which most likely resulted from the decomposition of fluorescent light ballasts or automotive switches that may have been disposed in the landfill trench. In addition, the Chloride, Sulfate and Total Dissolved Solids concentrations from all six groundwater wells exceed their respective Secondary MCLs.

The groundwater flow direction has been calculated at South 550 East with a gradient of 0.12’/foot.

However, it is the opinion of AEC that the groundwater elevations are tidally influenced; therefore, AEC will return to the site and collect depth to water readings during a consecutive “high” and “low” tide event.
