MEMORANDUM WESTERN PLACER WASTE MANAGEMENT AUTHORITY

TO: WPWMA BOARD OF DIRECTORS DATE: MARCH 14, 2019 FROM: KEN GREHM / KEITH SCHMIDT SUBJECT: SECOND AMENDMENT TO THE AGREEMENT WITH SCS

ENGINEERS FOR WATER QUALITY MONITORING AND REPORTING SERVICES

RECOMMENDED ACTION: Authorize the Chair to sign the Second Amendment to the Water Quality Monitoring and Reporting Agreement (Agreement) with SCS Engineers (SCS), extending services for an additional year and authorizing additional related services, for a total of $342,500, increasing the total not-to-exceed cost of the Agreement to $754,400. BACKGROUND: The WPWMA has historically contracted with a firm to provide regular water quality monitoring and reporting services as part of the facility’s Waste Discharge Requirements. These services include routine quarterly sampling; laboratory analysis; desktop analysis; and reporting for stormwater, compost leachate, groundwater and the water vapor entrained in the soil above the groundwater. After a competitive procurement process, your Board approved an Agreement with SCS on July 13, 2017. SCS has been responsive, competent and professional in providing services for the term of the current Agreement, and staff recommends extending the Agreement for an additional one-year term to continue these services. In addition, as noted in the February 14, 2019 WPWMA Engineer’s report to your Board, the WPWMA received a Notice of Violation (NOV) from the Central Valley Regional Water Quality Control Board (Water Board). The NOV: 1) alleges that Modules 5 may have a compromised liner system, 2) requires the WPWMA submit an updated Report of Waste Discharge (ROWD) to reopen the permitting process, 3) requires the WPWMA submit a revised Corrective Action Plan (CAP) related to groundwater impacts near the unlined area of the landfill, 4) requires repair or replacement of damaged leachate sump access pipes, and 5) requires additional monitoring and reporting. Conducting the required analysis and preparing all reports noted above requires a broad and detailed knowledge of the Western Regional Sanitary Landfill, site history, current practices, and water quality monitoring trends all of which SCS has. Staff requested a proposal from SCS to prepare the analysis, reports and design required by the NOV, and negotiated the attached Second Amendment with new tasks for these additional services. Staff will return to your Board with any design documents produced by SCS for authorization to solicit construction bids. ENVIRONMENTAL CLEARANCE: All work required under this Agreement is categorically exempt under CEQA Guidelines, Article 19, Section 15306 “Information Collection”, which allows for data collection when

7

WPWMA BOARD OF DIRECTORS SECOND AMENDMENT WITH SCS FOR WATER QUALITY MONITORING AND REPORTING SERVICES MARCH 14, 2019 PAGE 2 such activities do not result in a serious or major disturbance to an environmental resource. FISCAL IMPACT: The cost of providing the services included in the attached Scope is $342,500, $192,000 of which is for routine water quality monitoring services, $10,000 is reserved for Additional Services, and the remainder is for non-recurring studies and design related to the NOV. Amendment 2 would increase the total not-to-exceed cost of the Agreement to $754,400. Sufficient funding for these services is included in the FY 2018/19 Budget. ATTACHMENT: SECOND AMENDMENT

6. WPWMA staff reviewed each of the proposals and believes Consultant understands the scope of work, has proposed a reasonable budget, and is uniquely suited to effectively complete the work given their current performance of water quality monitoring services for the WPWMA.

7. The WPWMA and Consultant acknowledge that, by providing these extended and additional services, the total cost of the Agreement shall increase to Seven Hundred Fifty Four Thousand Four Hundred Dollars ($754,400).

8. The WPWMA and Consultant desire to amend the Agreement to reflect the revised understanding between the parties as set forth below. All references in this Second Amendment to a Section, to an Appendix, or to an Exhibit shall refer to that Section or Exhibit of the Agreement, and all terms defined in the Agreement shall have the same meaning herein.

NOW THEREFORE, THE PARTIES AGREE AS FOLLOWS: a. Exhibit A, Scope of Services, shall be amended to add the following new Task 7 which

shall read in its entirety as follows: “TASK 7 – WATER BOARD RESPONSE REPORT Consultant shall prepare a response report to the Water Board addressing proposed actions to be taken under required tasks 2 through 17 of the NOV dated January 17, 2019 (Exhibit F). Consultant shall include an outline of the steps for submitting an amended Report of Waste Discharge to the Water Board. Consultant shall submit a draft response report to the WPWMA for review by March 25, 2019. Consultant shall incorporate WPWMA comments and submit a final response report to the Water Board via GeoTracker on or before April 1, 2019.”

b. Exhibit A, Scope of Services, shall be amended to add the following new Task 8 which shall read in its entirety as follows:

“TASK 8 – ENGINEERING FEASIBILITY STUDY The WPWMA detected Volatile Organic Compounds (VOCs) in groundwater samples from several monitoring wells at the Western Regional Sanitary Landfill (WRSL) as early as 1995. Historically, the first VOC detections were in groundwater samples from monitoring well MW-9, which is located immediately west of Module 2. The source of the VOCs appeared to be landfill gas (LFG). A Corrective Action Program (CAP) and Addendum were submitted to the Water Board on May 20, 1997, and September 23, 1997, respectively. The Water Board approved the CAP and its addendum in late 1997. The abovementioned NOV received January 17, 2019, indicates Water Board staff has determined that the WPWMA’s CAP no longer satisfies the requirements of Section 20430 of Title 27. Consultant shall conduct an Engineering Feasibility Study (EFS) to identify possible corrective action alternatives, screen alternatives to eliminate those that are infeasible

10

or prohibitively expensive, select potential alternatives for additional evaluation and cost estimating, and provide recommendations for the most cost-effective alternative(s) to address detected vadose zone and groundwater impacts. Consultant shall use the EFS as the basis for development of a new CAP for the WRSL. Consultant shall review and assemble relevant data from existing documents for current and past landfill impacts to groundwater, groundwater flow conditions, geologic conditions, landfill features and configuration, and landfilling practices. Using this data review, Consultant shall prepare a Conceptual Site Model (CSM) to define the known nature and extent of vadose zone and groundwater impacts, and the possible impact sources and transport mechanism(s). Consultant shall provide the CSM to the WPWMA for review and shall incorporate WPWMA comments into the final CSM as part of the EFS report. Consultant shall complete the EFS to assess possible remediation alternatives and evaluate them in terms of the ability to reduce current impacts from the landfill to the vadose zone and groundwater. Consultant shall use the following steps to prepare the EFS:

1. Prepare a CSM to define the known nature and extent of impacts 2. Identify technologies to be considered; 3. Conduct technology screening to eliminate those technologies that are not

feasible due to the nature of the impacts, known site conditions, unreasonable costs, or other implementation factors;

4. Conduct preliminary review and assessment of remaining technologies to determine the most practical, feasible, and cost effective technologies;

5. Assess other implementation factors including ability to permit, constructability, implementation schedule, and likely time to achieve compliance;

5. Assess and compare cost estimates of the top selected technologies sufficient to provide a comparison of cost-effectiveness, ranking, and recommendation of best technologies to be implemented or modified.

Consultant shall provide the draft EFS report to the WPWMA for review and comment, including the following components:

• The final CSM evaluation; • Identification of alternatives considered; • Technology screening process and rationale for eliminated alternatives; • Comparison of retained alternatives for anticipated effectiveness, cost,

implementation factors, and estimated schedule to attain groundwater compliance;

• Recommendation of preferred alternative(s); • Identification of additional field data collection activities, pilot testing, and/or

groundwater modeling, if necessary, to confirm viability of recommended alternative(s);

• Conceptual plans and budgetary construction and operational cost estimates for the recommended alternative(s);

• Monitoring plan for determination of alternative effectiveness.

11

Consultant shall incorporate WPWMA comments into a final EFS report for submittal to the Water Board via GeoTracker. Consultant shall also provide technical support for responses to subsequent comments received from Water Board. For purposes of this scope and budget, Consultant shall address one round of WPWMA and one round of Water Board comments to the EFS. Consultant shall submit the Draft EFS to the WPWMA eight (8) weeks from notice to proceed, and shall submit the Final EFS within two (2) weeks from receipt of WPWMA comments. Consultant shall accompany WPWMA staff to one (1) meeting with Water Board staff to present and discuss the EFS. Subject to the not-to-exceed budget of this task, Consultant shall provide all information requested by the Water Board in a timely manner and provide ongoing support to the WPWMA to respond to Water Board correspondence until this issue is resolved.”

c. Exhibit A, Scope of Services, shall be amended to add the following new Task 9 which shall read in its entirety as follows:

“TASK 9 – CORRECTIVE ACTION PROGRAM AND REPORT OF WASTE DISCHARGE Following completion of the EFS in Task 8, including receipt of comments from the Water Board indicating approval of the proposed technologies, Consultant shall prepare a revised Corrective Action Program (CAP) that describes the actions to be taken to address the requirements of California Code of Regulations (CCR) Title 27 §20430. Consultant shall prepare the CAP as a stand-alone document for ease of reference and possible future modification. Consultant shall provide a draft CAP to the WPWMA for review and comment and shall incorporate WPWMA comments into a final CAP. Consultant shall revise the existing Report of Waste Discharge (ROWD) components of the Joint Technical Document (JTD) to include the new CAP. Consultant shall provide a draft WRSL JTD to the WPWMA for review and comment and shall incorporate WPWMA comments into a final JTD for submittal to the Water Board via GeoTracker. Consultant shall submit the Draft CAP and JTD update documents within six (6) weeks from receipt of response and approval from the Water Board of the technologies selected in the EFS, and the Final CAP and JTD update documents within two (2) weeks of receipt of WPWMA comments.”

d. Exhibit A, Scope of Services, shall be amended to add the following new Task 10 which shall read in its entirety as follows:

“TASK 10 – MODULE 5 DATA EVALUATION In the NOV included in Exhibit F, the Water Board alleged WRSL Module 5 may have a compromised liner system based on the presence of liquid exhibiting trace or low levels of VOCs, and variable levels of other constituents in the leak detection and lysimeter layers of the liner system.

12

Consultant shall conduct an in-depth evaluation of all available relevant historic groundwater, leachate, and LFG data, including graphical and statistical analysis, to determine the probability the liner system is compromised. For purposes of this scope and budget, Consultant and WPWMA have assumed that no additional sampling or laboratory analysis will be required. Consultant shall prepare and submit a Draft Impact Study Report summarizing their findings to the WPWMA for review within six (6) weeks of notice to proceed. Consultant shall submit a Final Impact Study Report to the WPWMA within two (2) weeks of WPWMA comments on the draft. Consultant shall accompany WPWMA staff to one (1) meeting with Water Board staff to present and discuss findings. Subject to the not-to-exceed budget of this task, Consultant shall provide all information requested by the Water Board in a timely manner and provide ongoing support to the WPWMA to respond to Water Board correspondence until this issue is resolved.”

e. Exhibit A, Scope of Services, shall be amended to add the following new Task 11 which shall read in its entirety as follows:

“TASK 11 – WATER QUALITY PROTECTION STANDARD Consultant shall review all groundwater and vadose zone monitoring data to determine if the required work stated in the Water Board letter is feasible. Consultant has assumed all historic groundwater and vadose zone monitoring data are available to Consultant in an electronic format suitable for use in statistical analyses. Consultant shall review the basis for determining background conditions in groundwater and the vadose zone, including statistical procedures used. If data are insufficient for calculation of concentration limits in groundwater and/or the vadose zone, Consultant shall make recommendations for additional monitoring to achieve the necessary data. Based on the data review, Consultant shall prepare a new Water Quality Protection Standard Report (WQPSR) to address requirements of the Water Board and applicable law. Consultant may also propose changes in the concentration limit calculation methodologies as appropriate. The WQPSR shall contain the elements defined in CCR Title 27 § 20390 including definition of the constituents of concern, concentration limits, identification of points of compliance and monitoring points, and the estimated compliance period. Consultant shall prepare the WQPSR in draft format for review and comment by WPWMA. After receiving comments from WPWMA, Consultant shall prepare a final version of the WQPSR and upload the report to the State’s GeoTracker system. Consultant shall submit the Draft WQPSR within four (4) weeks of notice to proceed, and submit the Final WQPSR within two weeks of receipt of comments from the WPWMA.”

13

f. Exhibit A, Scope of Services, shall be amended to add the following new Task 12 which shall read in its entirety as follows:

“TASK 12 – DESIGN OF LEACHATE SUMP RISER REPAIRS The Waste Discharge Requirements (WDRs) obligate the WPWMA to establish and maintain a leachate collection system to evacuate landfill leachate from the surface of the liner, and to maintain access to that system for continued operation. For reasons unknown at this time, the leachate sump access pipe for Module 2 and possibly Module 12 were damaged and at least partially impeded sampling and liquid level measurement. Also, the access pipe for Module 10 leachate sump was badly damaged in the subsurface oxidation event detected in May 2016. Repairs or replacement are required to fully comply with the WDRs. Consultant shall review the following design and construction documents:

• As-Built Design Drawings of all constructed Modules (lined and unlined). • As-Built Design of the existing Gas Collection and Control System (GCCS). • Review of field data (from former consultants) and field findings from Consultant

field review of the current GCCS system. Once Consultant has received PDF (and AutoCAD where available) electronic files from the WPWMA, Consultant shall review the sump details for each module and investigate field problems that may have occurred for each sump. Consultant shall determine which sumps need to be repaired/replaced, in addition to those that have already been identified – sumps M-2, M-10 and M-12. Consultant shall prepare a technical memorandum identifying all sumps that require repair or replacement with recommendations. Consultant shall develop conceptual drawings, based on its review and field investigation findings. For purposes of this scope and budget, Consultant shall prepare a design(s) for replacement sumps at M-2, M-10 and M-12. If repairs or replacements to other sumps are necessary, Consultant shall immediately notify the WPWMA and may be asked to submit a separate proposal. Consultant’s design shall include the following deliverables.

• Conceptual design o A comparison of design options and original sump design. o Options for connecting the sump access pipes to the nearest force-main

used for condensate and leachate disposal. o Consultant shall submit the conceptual design for WPWMA review and

approval prior to developing the design plans. • 50% design

o Includes sump (potentially multiple sumps) details and ancillary piping connections.

o 50% and Final deliverable will include, but may not be limited to, the following design Sheets: Title Sheet Existing GCCS Plan

EXHIBIT F JANUARY 17, 2019 WATER BOARD NOTICE OF VIOLATION

20

17 January 2019 Bill Zimmerman Deputy Executive Director Western Placer Waste Management Authority 11476 C Avenue Auburn, CA 95603 NOTICE OF VIOLATION, MONITORING REPORT REVIEW, AND REQUEST FOR ADDITIONAL SITE WORK AND AMENDED REPORT OF WASTE DISCHARGE, WESTERN REGIONAL SANITARY LANDFILL, PLACER COUNTY The Western Placer Waste Management Authority (hereafter Discharger) operates the Western Regional Sanitary Landfill, which is regulated by Waste Discharge Requirements (WDRs) Order R5-2007-0047. The facility consists of two waste management units (WMU), a partially closed Class III WMU, which consists of six individual modules; Modules 1, 2, 10, 11, 12, and 13, and a Class II WMU, which currently consists of four modules; Modules 5, 14, 15, and 16. Modules 1, 2, 10, and a portion of Module 11 are unlined; however, the remaining modules are lined and have an overlaying leachate collection and removal system (LCRS). Water Board staff reviewed the Discharger’s 19 December 2018, Third Quarter 2018 Water Quality Monitoring Report. Outlined below is a list of violations as well as Water Board staff concerns. There is also a discussion regarding the site’s current Corrective Action Program, and a list of site work required to come into and maintain compliance with the WDRs and Title 27. Violations: A. In 2018, one or more volatile organic compounds (VOCs) and/or inorganic constituents were

detected above their respective concentration limits in wells MW-5, CW-5S, CW-5M, CW-5D, MW-9, CW-9S, CW-9M, CW-9D, MW-10; MW-11R, MW-13, CW-7S, CW-7M, MW-18, CW-19S, CW-19M, CW-25S, CW-25M, and MW-23R.

The presence of VOCs and/or inorganic exceedances in groundwater outside any WMU’s containment structure constitutes a violation of Prohibition A.2 of the WDRs, which states in part:

“The discharge of wastes outside of a Unit or portions of a Unit specifically designed for their containment is prohibited.”

21

Bill Zimmerman 2 17 January 2019 Western Regional Sanitary Landfill

B. In 2018 multiple VOCs including 1,1-dichloroethane 1,2-dichloroethane, ethylbenzene, methyl tert-butyl ether, 1,4-dichlorobenzene, 1,2-dichloropropane, toluene, and most notably 1,300 ug/L tert-Butyl alcohol and 3.0 g/L benzene were detected in lysimeter M-16 LY South. Additionally, up to 0.38 ug/L 1,4-dichlorobenzene and 0.55 ug/L toluene were detected in lysimeter S-15, and up to 0.19 ug/L trichlorofluoromethane and up to 0.42 ug/L toluene were detected in M16 LY West. The detection of VOCs outside any WMU’s containment structure constitutes a release, in violation of Prohibition A.2 of the WDRs, as quoted in Violation A above.

C. On 13 December 2016, methane levels exceeded required regulatory limits in perimeter gas

probes GM-3M and GM-3D, and by January 2017, additional perimeter gas probes were impacted. In the fourth quarter 2017, methane levels exceeded regulatory limits in perimeter gas probe GM-18, and in 2018 methane levels exceeded regulatory limits in GM-2 and GM-14.

These methane exceedances in soil gas, which have continued since December 2016, as documented in corresponding LEA inspection reports, including the most recent 10 December 2018 inspection report, are a violation of Section 20921(a)(2) of Title 27, which state in part:

“The concentration of methane gas migrating from the disposal site must not exceed 5% by volume in air at the disposal site permitted facility boundary or an alternative boundary approved in accordance with § 20925.”

On 7 January 2019, Placer County issued an Order to the Discharger for these violations, which required them to submit a Wellfield Improvement Design plan by 1 July 2019, and to complete construction of the Wellfield Improvement Design plan by 31 October 2019.

D. Elevated concentrations of bicarbonate along with select VOCs were detected in each of the

site’s three independent leak detection sumps; M-5 LD, M-16 LD South, and M-16 LD West, during the third quarter 2018. Sump M-5 LD contained benzene, 1,1-dichloroethane, 1,2-dichloroethane, cis-1,2-dichloroethene, vinyl chloride, and toluene. Sump M-16 LD South contained benzene, 1,1-dichloroethane, 1,2-dichloroethane, cis-1,2-Dichloroethene, ethylbenzene, methyl tert-butyl ether, tert-Butyl alcohol, total xylenes, 1,4-dichlorobenzene, 1,2-dichloropropane, vinyl chloride, and toluene. Sump M-16 LD West contained benzene, 1,1-dichloroethane, 1,2-dichloroethane, cis-1,2-dichloroethene, ethylbenzene, methyl tert-butyl ether, tert-Butyl alcohol, total xylenes, 1,4-dichlorobenzene, 1,2-dichloropropane, naphthalene, vinyl chloride, and toluene.

If liquid is detected in the underlying leak detection layer of a Module, Discharge Specification B.7 of the WDRs requires the Discharger to immediately cease the discharge of sludges and other high-moisture containing wastes to that module and to propose corrective action necessary to reduce leachate production.

22


E. Concentration limit exceedances were recorded for diethyl-phthalate, arsenic, manganese and vanadium during the 9 January 2018 surface water Constituent-of-Concern (COCs) sampling event, in violation of Prohibition A.9, which state:

“The discharge of solid or liquid waste or leachate to surface waters, surface water drainage courses, or groundwater is prohibited.”

F. Unsaturated zone monitoring data was only provided for lysimeters M-5LY, S-15,

M-16 LY South, and M-16 LY West in violation of Section A.3, Section D.2, and TABLE II of Monitoring and Reporting Program (MRP) R5-2007-0047. These sections of the MRP require all unsaturated zone monitoring points to be monitored and sampled semi-annually. These unsaturated zone monitoring points include; 1) suction lysimeters BG-A/B, S10-A/B, S11-A/B, S12-A/B, S13-A/B , S14-A/B, S-15, S16-A/B, M-5 LY, S-15R, M-16 LY SR, and M-16 LY WR, and 2) pan lysimeters S-15 (M-15 LY), M-5 LY, M-16 LY South, M-16 LY West.

G. In May 2016, Leachate Sump M-10 was damaged due to an underground fire. Leachate

Sump M-2 was last monitored on 22 March 2018, due to a pinched casing, and Sump M-14 could not be sampled in the Third Quarter 2018, due to a pinched casing. Failure to repair and resume monitoring and sampling of these monitoring points is a violation of Facility Specification C.6, which states:

“The Discharger shall maintain in good working order any facility, control system, or monitoring device installed to achieve compliance with the waste discharge requirements.”

H. No monthly leachate flow rates in gallons/day, electrical conductivity readings, or pH

readings are contained in the site’s monitoring reports, as required by Section A.4, D.3 and TABLE III of the MRP.

I. Groundwater samples were not analyzed for bromobenzene, n-butylbenzene,

sec-butylbenzene, tert-butylbenzene, hexachloroethane, and 2-Nitropropane, as required by Section A.1, Section D.1, and Tables I and V of the MRP.

Additional Staff Concerns J. The Discharger has failed to complete all required GeoTracker uploads and has intermixed

mean sea level (MSL) and below ground surface (BGS) data on select groundwater elevation data uploads to GeoTracker.

K. Background wells LW-1 and MW-1 are not depicted on maps in any of the Discharger’s

monitoring reports. L. Table C3 in the Discharger’s monitoring reports only contains depth and liquid level

elevation data for select leachate sumps. This depth and liquid level elevation data is required to assess compliance with General Construction Specifications D.7 of the WDRs.

23


M. Water quality protection standard (WQPS) concentrations limits have not been established for calcium, magnesium, potassium, and sodium in groundwater, and for bicarbonate, calcium, magnesium, potassium, and sodium in the unsaturated zone. In addition to chloride and sulfate, these listed inorganic constituents are the primary inorganic indicator parameters for the detection of a release from a WMU. Concentration limits for these primary inorganic indicator parameters will be required.

N. Well completion data including; 1) elevation, 2) screen placement, 3) screen length, and

4) pump placement are not provided in the Discharger’s monitoring reports. This well construction data is essential to adquetly assess site conditions, the effectives of corrective action, and determine compliance with the site’s WDRs and Title 27.

Corrective Action Discussion Section 20430(b) of Title 27 states in part:

“The discharger shall take corrective action to achieve the following goals: to remediate releases from the Unit; to ensure that the discharger achieves compliance with the Water Standard adopted under § 20390 for that Unit.”

Section 20430(c) of Title 27 states in part:

“The discharger shall implement corrective action measures that ensure that COCs achieve their respective concentration limits at all Monitoring Points and throughout the zone affected by the release, including any portions thereof that extend beyond the facility boundary, by removing the waste constituents or treating them in place.”

VOCs were first observed in groundwater beneath the site in 1995, and the Discharger attributed the source of the VOCs to landfill gas (LFG). Subsequently, to address the release, the Discharger established a corrective action program in 1997, which consisted of installing a final cover atop Modules 1, 2, 10, and 11, and extracting LFG from the closed modules. It has been over 20 years since the Discharger began corrective action, yet VOCs and select inorganics, primarily bicarbonate, continue to persist in groundwater beneath the site and along the site boundary, even with the expansion of the site’s LFG extraction system. Furthermore, methane concentration exceedances have been recorded in soil gas outside the site’s WMUs, and VOCs have been detected in the subsurface beyond waste Module 16, which is located at the far southwestern/downgradient side of the site. Therefore, Water Board staff has determined that the Discharger’s corrective action program no longer satisfies the requirements of Section 20430 of Title 27. Subsequently, in accordance with Section 20430(j) of Title 27, the Discharger will be required to submit an amended report of waste discharge (ROWD) to make appropriate changes to the site’s corrective action program. The amended ROWD shall be adequate to address constituent impacts to both groundwater and the unsaturated zone, and to provide monitoring adequate to define the extent of the release and demonstrate the effectiveness of proposed corrective action measures, as required by Section 20430(d) of Title 27. The amended ROWD, must also contain a schedule for the implementation of the proposed corrective action measures, as well as the expected time line for the completion of corrective action in accordance with Section 20430(e).

24


Section 20430(e) of Title 27 states in part:

Corrective action measures taken pursuant to this section shall be initiated and completed by the discharger within a period of time specified by the RWQCB in the WDRs.

Required Work: To address the violation and Water Board staff concern outlined above, and ensure compliance with the WDRs and Title 27, Western Placer Waste Management Authority shall complete each of the follow tasks.

1. Submit an amended ROWD, by 1 July 2019, to make appropriate changes to the site’s corrective action program as discussed above. The proposal shall be adequate to contain and remediate constituent impacts to all impacted groundwater and unsaturated zones.

2. Submit to Water Board staff a copy of all written correspondence associated with

Placer County’s 7 January 2019 Order, including all required and subsequently issued directives, to control and reduce methane concentration in the unsaturated zone beneath and beyond the limit of the site.

3. In accordance with Discharge Specifications B.7 of the WDRs, immediately cease the

discharge of sludges and other high-moisture wastes to Modules 5 and 16, and submit by 1 July 2019, a proposal to complete corrective action necessary to reduce leachate production.

4. Analyze the next set of surface water samples for the four constituents detected during

the January 2018 5-year COC sampling event; diethyl-phthalate, arsenic, manganese and vanadium, in additional to the standard analytical suite required by the WDRs. If any of these constituents are detected, they shall be added to the standard annual analytical suite for surface water sampling; Table IV of the MRP. Additionally, if exceedances continue at any of the site’s three surface water sampling location (SW-1, SW-2 and SW-3), an updated Storm Water Pollution Prevention Plan (SWPPP), to address all detected constituents, shall be submitted to the Stormwater Multiple Application and Report Tracking System (SMARTS).

5. Complete and document in tables current and all historical unsaturated zone monitoring,

as required by Section A.3, Section D.2, and TABLE II of the MRP for all unsaturated zone monitoring points, including; suction lysimeters BG-A/B, S10-A/B, S11-A/B, S12-A/B, S13-A/B , S14-A/B, S-15, S16-A/B, M-5 LY, S-15R, M-16 LY SR, and M-16 LY WR, and pan lysimeters S-15 (M-15 LY), M-5 LY, M-16 LY South, M-16 LY West. If an attempt to sample was made, but a sample could not be collected, the attempt to sample, along with the reason a sample could not be collected, should be documented in the table. All sampling attempts must be documented to show compliance with the WDRs, even if a sample could not be collected.

25


Additionally, if the County is unable to recover a sample after two consecutive sampling events, from any of these lysimeters, the County is to submit a work plan to reinstall the device.

6. Repair leachate sumps M-2, M-10, and M-14 to ensure each sump can be accessed,

monitored, and sampled.

7. Provide tables in all future monitoring reports that document current and all historical monthly field parameter readings, as outlined in Table III of the MRP, obtained from each of the site’s 10 leachate sumps. These field parameters include; 1) total flow, 2) monthly flow in gallons/day, 3) electrical conductivity readings, and 4) pH readings.

8. Analyze each collected groundwater sample for each constituent outlined in Tables I and

Table V of the MRP, as required by Section A.1 and Section D.1 of the MRP.

9. Upload to GeoTracker a report documenting the installation of the CW wells; CW-5A/B/C, CW-7A/B/C, CW-9A/B/C, CW-19A/B/C, and CW-25A/B/C.

10. Upload to GeoTracker the boring logs for each CW well; CW-5A/B/C, CW-7A/B/C,

CW-9A/B/C, CW-19A/B/C, and CW-25A/B/C. 11. Upload to GeoTracker X, Y, and Z coordinate data for each site wells. This data, along

with all data uploaded to GeoTracker, must be completed in accordance with established GeoTracker reporting requirements.

12. Ensure consistent groundwater elevation data is uploaded to GeoTracker per

GeoTracker reporting requirements. The Discharger has uploaded some groundwater elevation data in feet above MSL and other data in feet below ground surface BGS.

13. Provide a map in all future monitoring reports that shows the location of background

wells LW-1 and MW-1. Given their location and distance from the site, they may be able to be shown on the Site Location Map, Figure 1 in the monitoring reports.

14. Calculate and propose WQPS concentration limits in groundwater beneath the site for

calcium, magnesium, potassium, and sodium.

15. Calculate and propose WQPS concentrations limits in the unsaturated zone beneath the site for bicarbonate, calcium, magnesium, potassium, and sodium.

16. Update Table C3 in all future monitoring reports, so that it contains 1) Sump Bottom

Elevations, 2) Liner Bottom Elevations, and 3) the depth at which water levels in each sump exceed the permitted amount allowed atop each modules liner.

17. Provide a table in all future monitoring reports that documents the completion details of

each site well, including: 1) the elevation of the well, 2) the total depth of the well, 3) the elevation at the top of the screened interval, 4) screen length, 5) the elevation at the bottom of the screened interval, and 6) the elevation at which each wells dedicated pump, if installed, is placed.

26

TO: WPWMA BOARD OF DIRECTORS DATE: MARCH 14, 2019 FROM: KEN GREHM / KEITH SCHMIDT SUBJECT: AGREEMENT WITH WORKSMART FOR SCADA SYSTEM SERVICES

RECOMMENDED ACTION: Authorize the Executive Director or designee, upon review and approval by WPWMA Counsel, to sign an Agreement with WorkSmart Automation, Inc. (WorkSmart) for on-call Supervisory Control and Data Acquisition (SCADA) support services related to the WPWMA’s landfill gas operations for an amount not-to-exceed $35,000. BACKGROUND: WorkSmart configured the new SCADA system installed with the LFG Blower/Flare Station project in December 2017. The SCADA system monitors flare operations and operator settings, and includes automated reporting capabilities. The automated reports reduce the time required and cost experienced by staff and the system operator in evaluating system performance and complying with multiple regulatory reporting requirements. Staff recommends entering into an agreement with WorkSmart to provide additional SCADA system support on an as-needed basis which could include efforts such as developing customized reports suitable for submittal to regulatory agencies and working with Energy 2001 to configure the data connection from their facility for enhanced troubleshooting and further automated reporting. The WPWMA will continue to rely on Placer County IT staff for routine SCADA support and maintenance. ENVIRONMENTAL CLEARANCE: All work required under this Agreement is categorically exempt under CEQA Guidelines, Article 19, Section 15306 “Information Collection”, which allows for data collection when such activities do not result in a serious or major disturbance to an environmental resource. FISCAL IMPACT: Staff anticipates that the cost of providing the proposed services will not exceed $35,000. Sufficient funding for these services is included in the FY 2018/19 Budget.

TO: WPWMA BOARD OF DIRECTORS DATE: MARCH 14, 2019 FROM: KEN GREHM /KEITH SCHMIDT SUBJECT: PROJECT 02607A – COMPOST POND LYSIMETER CONSTRUCTION:

NOTICE OF COMPLETION RECOMMENDED ACTION: Adopt Resolution 19-01 accepting Project 02607A – South Compost Pond Pan Lysimeter Construction as complete, and authorizing the Executive Director or designee to execute and file the attached Notice of Completion. BACKGROUND: On July 12, 2018, your Board authorized staff to solicit bids for the Compost Pond Lysimeter project and authorized the Executive Director or designee to execute the resulting agreement. The Deputy Executive Director executed an agreement with BWD General Engineering Contractors (BWD) in the amount of $121,500 on August 31, 2018 and staff issued a Notice to Proceed on September 10, 2018. The project consisted of construction of a pan lysimeter in the south compost pond to provide for early detection of potential releases to groundwater to comply with the Central Valley Regional Water Quality Control Board’s (Water Board) statewide general permit for composting facilities. There was no requirement for a pan lysimeter at the time the pond was originally constructed in 2012 or modified in 2014. One contract change order (CCO) totaling $76,835 was issued during the project to address conditions of approval established by the Water Board during the permitting process1, including: 1) $46,835 to install a geocomposite clay liner under the section of liner being modified and related additional materials testing, and 2) $30,000 on a time and materials basis to clean the liner so that the WPWMA could conduct an electronic leak detection survey of the entire liner system2. Approximately 12 small holes were found in the old pond liner, and BWD repaired those holes within the cost allowance noted above. A summary of the contract changes is included with the attached supplemental information sheet. Project construction began September 12, 2018 and was substantially completed on November 19, 2018. ENVIRONMENTAL CLEARANCE: Filing the Notice of Completion is not considered a “project” pursuant to California Environmental Quality Act (CEQA) Guidelines, Article 20, Section 15378 as it is an administrative activity that will not result in a physical change in the environment.

1 The WPWMA submitted design plans for the Water Board’s review on July 11, 2019, and received Water Board comments on

September 8, 2019. Given the need to complete the work by November 30, 2019 deadline previously agreed to by the Water Board, and the risk of cost overruns for constructing a liner project in the wet season, staff elected to proceed with construction activities prior to receiving final written approval from the Water Board on the final design.

2 As part of the 2012 and 2014 construction efforts, the WPWMA conducted a leak detection survey on the entire liner system.

TO: WPWMA BOARD OF DIRECTORS DATE: MARCH 14, 2019 FROM: KEN GREHM / KEITH SCHMIDT SUBJECT: SOLE-SOURCE SERVICE AGREEMENT WITH ENVIROSUITE FOR

ODOR MONITORING SYSTEM SOFTWARE & MAINTENANCE

RECOMMENDED ACTION: Authorize the Executive Director or designee, upon review and approval by WPWMA Counsel, to sign a three-year sole-source service agreement with Envirosuite Corp. for routine maintenance, support and operational upgrades of the WPWMA’s continuous odor monitoring system for an amount not to exceed $150,000. BACKGROUND: Beginning in 2011, the WPWMA has undertaken a series of efforts to address odors associated with its facility including: facility enhancements and upgrades ahead of legally required timeframes, exploring and (where appropriate) implementing changes to operations, streamlining the process for the public to report odors, establishing greater engagement with nearby residents to discuss facility operations and resulting odors, and employing systems to measure and record on-site odors. To facilitate the measurement of odors, the WPWMA installed a continuous odor monitoring system in 2014 to provide for a more accurate and quantifiable analysis of the dispersion of odors generated at the WPWMA’s facility. The system, designed by Odotech, includes four odor collection sensors, a proprietary web-based software program (OdoWatch), server, and weather station. Since the initial system installation, Odotech was acquired by Envirosuite Corp. (Envirosuite); as a result, effective July 1, 2019, Envirosuite will no longer support the OdoWatch system. In order to keep the odor monitoring system functional, WPWMA will need to transition to Envirosuite’s proprietary web-based software program before the aforementioned date. The Envirosuite software will offer the same features as OdoWatch, which includes continuous monitoring of facility conditions by providing data collected from onsite odor sensors, and the ability to analyze offsite impacts through air dispersion modeling estimates. In addition to these basic features, Envirosuite also offers several extra capabilities that WPWMA staff believes will be beneficial in further assessing odors from both WPWMA and non-WPWMA facilities in the region. The two primary additional features include a “reverse trajectory” algorithm and predictive modeling. The reverse trajectory algorithm would allow staff to trace the pathway of an odor, based on the location of a submitted odor notification and weather conditions, providing staff the opportunity to better identify the likely source responsible for the odor notification. The predictive modeling would allow staff to estimate the most favorable time to perform certain facility operations based on weather conditions, to help minimize the potential migration of odors from the WPWMA’s facility.

35

WPWMA BOARD OF DIRECTORS SERVICE AGREEMENT WITH ENVIROSUITE MARCH 14, 2019 PAGE 2

A subscription for both the basic and additional features of the Envirosuite software is available at the same cost as the previous contract with Odotech. Based on the WPWMA’s reliance of the continuous odor monitoring system for investigating reported odors, and Envirosuite’s knowledge of our equipment and system, staff recommends your Board authorize the Executive Director or designee to execute a sole-source agreement with Envirosuite for the software upgrade, maintenance, and support services. The proposed service agreement provides for labor, parts and materials necessary to maintain system performance, including: conducting regular system testing, preventative maintenance and routine software and licensing upgrades. The proposed agreement also includes funds for operational upgrades to further customize the system to the WPWMA’s needs as necessary. ENVIRONMENTAL CLEARANCE: Entering into a service agreement for the WPWMA’s odor monitoring system is categorically exempt from further environmental review pursuant to Section 15301 “Existing Facilities” of the CEQA guidelines which provides for operation, repair, maintenance and minor alteration of existing public structures. FISCAL IMPACT: The cost of providing the proposed Scope of Services for each year of the three-year Agreement is $50,000, which includes $34,000 for the planned services and $16,000 per year for system repairs or upgrades as requested by the WPWMA. Funding for this year’s $50,000 is included in the FY 2018/19 Budget. ATTACHMENT: SCOPE OF SERVICES

TO: WPWMA BOARD OF DIRECTORS DATE: MARCH 14, 2019 FROM: KEN GREHM / ERIC ODDO SUBJECT: WASTE ACTION PLAN NOTICE OF PREPARATION

RECOMMENDED ACTION: Approve the Renewable Placer: Waste Action Plan Notice of Preparation (NOP) and authorize staff to issue the NOP in accordance with California Environmental Quality Act (CEQA). BACKGROUND: Over the past two years, staff and Jacobs have engaged in a master planning process (Renewable Placer: Waste Action Plan) resulting in analysis and development of potential reconfigurations of the WPWMA’s properties to meet the long-term solid waste needs of the WPWMA and its Member Agencies. As a result of the Waste Action Plan process, two facility site layout plan (Plan) concepts were developed that staff believes best meet the WPWMA’s goals. At the December 13, 2018 meeting, your Board authorized staff to initiate environmental review of both Plan concepts as equal weight alternatives. In accordance with CEQA, the WPWMA is required to prepare and issue an NOP as the first step in the environmental impact report (EIR) development process. The NOP is intended to notify the appropriate agencies and other interested parties that the WPWMA is initiating an EIR process and afford them the opportunity to provide comments on significant environmental issues, reasonable alternatives, and possible mitigation measures that the WPWMA should address in its EIR. At a minimum, the NOP is required to include a brief description of the proposed project, the location of the proposed project with applicable maps, and the probable environmental effects of the proposed project. WPWMA and Jacobs staff developed a draft NOP which was presented to, and discussed with, the Member Agency Advisory Committee. Following input from this group, Jacobs revised the draft NOP which is provided in Attachment B for your Board’s consideration. Once approved by your Board, staff will post the NOP on a website set up by the WPWMA specifically for the Waste Action Plan EIR process (www.renewableplacer.com) and will issue the NOP to the agencies and interested parties (via certified mail) identified in Attachment A. Staff has tentatively scheduled release of the NOP for Friday March 15, 2019 (pending your Board’s approval of the NOP) for a 30-day review and comment period. Additionally, staff will be conducting a public Scoping Meeting to discuss the proposed project and EIR process on Monday April 1, 2019 at 6:00 pm at the WPWMA’s Administrative Offices.

NOTICE OF PREPARATION

DATE: March 15, 2019

TO: Agencies and Interested Parties

FROM: Western Placer Waste Management Authority

SUBJECT: Notice of Preparation of a Draft Environmental Impact Report for the Renewable Placer: Waste Action Plan

REVIEW PERIOD: March 15, 2019 to April 15, 2019

The Western Placer Waste Management Authority (WPWMA) is the lead agency and will prepare an Environmental Impact Report (EIR) for the Renewable Placer: Waste Action Plan (proposed project), which is described in detail below. In compliance with the California Environmental Quality Act (CEQA) (Public Resources Code [PRC] Section 21000 et seq.), WPWMA is distributing this Notice of Preparation (NOP) to the Office of Planning and Research, each responsible agency, interested parties, and federal agencies involved in approving the project, and to trustee agencies responsible for natural resources affected by the project.

PURPOSE OF THIS NOTICE OF PREPARATION

In accordance with the State CEQA Guidelines (14 California Code of Regulations [CCR] Section 15082), WPWMA has prepared this NOP to inform agencies and interested parties that an EIR will be prepared for the proposed project. The purpose of an NOP is to provide sufficient information about the proposed project and its potential environmental impacts to allow agencies and interested parties the opportunity to provide a meaningful response related to the scope and content of the EIR, including mitigation measures that should be considered and alternatives that should be addressed (State CEQA Guidelines 14 CCR Section 15082[b]).

PROJECT BACKGROUND

The WPWMA is a regional authority established in 1978 through a joint exercise of powers agreement between Placer County and the cities of Lincoln, Rocklin, and Roseville (Member Agencies) to own, operate and maintain a sanitary landfill and all related improvements. Member Agencies are provided with solid waste recycling, recovery, and disposal services at WPWMA facilities, which consist of the Western Regional Sanitary Landfill and a Materials Recovery Facility (MRF) that includes composting, household hazardous waste acceptance, and recycling and buyback facilities. In addition, the WPWMA leases approximately 15,000 square feet of land and delivers landfill gas to a private company to operate a landfill gas-to-energy plant for the purposes of generating electricity.

The WPWMA also provides solid waste services to the cities of Auburn and Colfax and the Town of Loomis; these entities and the Member Agencies are collectively referred to as Participating Agencies. The WPWMA’s current facility provides the majority of solid waste and recycling services to the Participating Agencies.

WPWMA’s facilities have adapted over the years to support evolving community needs, and today include Placer County’s only active landfill. Since its inception, the WPWMA has planned for the future of its Participating Agencies, including: constructing the MRF in 1995 and expanding it in 2007 to assist jurisdictions in complying with state recycling mandates; purchasing the western and eastern adjacent properties for potential future solid waste management operations and conducting early CEQA review of the western property for landfilling; expanding the composting area capacity in 2011 to accommodate increased green waste material produced in the region; providing facility access for new and emerging solid waste conversion technology pilot studies; and partnering with a local university to promote research and development opportunities.

Placer County is the second fastest growing county in California and its population is expected to nearly double in the next 30 years according to California State Department of Finance, Population Projects for California and Its Counties 2000-2050 (July 2007). In addition to projected population increases, Placer County jurisdictions are

seeking ways to respond to simultaneous restrictions in global recycling markets and increasingly stringent state-mandated limitations on materials that can be placed in California’s landfills.

In 2015, the WPWMA initiated a master planning effort identified as Renewable Placer: Waste Action Plan (Waste Action Plan). The Waste Action Plan is being developed to identify the physical and operational changes needed to WPWMA facilities and operations to ensure that the WPWMA’s facilities support future waste management and recycling needs for the rapidly growing communities it serves while complying with an increasingly complex regulatory environment. The Waste Action Plan is also being developed to maintain a stable cost structure for Participating Agencies, to improve operational efficiencies and customer safety, and to enhance compatibility between ongoing operations and current and future adjacent land uses.

PROJECT LOCATION

The proposed project is located on WPWMA’s existing properties, generally at the intersection of Fiddyment Road and Athens Avenue (Figures 1, 2 and 3), which consist of the following, totaling approximately 928 acres:

Approximately 155-acre eastern property, which is used for cattle grazing and is not currently permitted for solid waste operations;

Approximately 314-acre center property, which includes the Western Regional Sanitary Landfill (WRSL) and associated solid waste infrastructure, including a public waste and recyclables drop-off area, compost area, construction and demolition (C&D) processing area, MRF, and household hazardous waste collection area; and

Approximately 459-acre western property, a portion of which is currently leased to the City of Lincoln for discharge of reclaimed water and a portion of which is leased for model airplane operations. This property has been subject to environmental review and a Conditional Use Permit to operate a landfill has been previously granted by the Placer County Planning Commission; however, the property has not been fully permitted for waste disposal.

WPWMA’s mailing address is 3013 Fiddyment Road, Roseville, CA, 95747; the project site includes the following Assessor Parcels:

PROJECT DESCRIPTION

Two potential plan concepts were identified by the WPWMA for detailed analysis in the Waste Action Plan EIR. These two different approaches to implementing the Waste Action Plan, identified as Plan Concept 1 and Plan Concept 2, include similar elements but the locations and characteristics of the elements vary among the two plans. The description provided below identifies the common elements that are included in both plan concepts. These are divided into solid waste project elements, complementary/programmatic elements, and supporting elements. This summary of the project elements is followed by a description of the unique characteristics of each plan concept.

Solid Waste Project Elements are the project elements that are needed to continue providing solid waste management services to WPWMA’s Participating Agencies in the near and long term. These project elements include the following:

Expanded Landfill Capacity – The site’s landfill capacity is proposed to be expanded to accommodate current and future Participating Agency solid waste disposal demands;

Existing Solid Waste Excavation – Closed and pre-Subtitle D1 portions of the landfill are proposed to be excavated and relocated to a Subtitle D-compliant module.

Expanded and Redesigned Compost Operations – The compost operations are proposed to be redesigned to increase capacity to accommodate growth in the waste stream and increased organic diversion required by new compost regulations, to accept additional compostable material streams (e.g., food waste), and to improve odor control;

Expanded and Redesigned Construction and Demolition Waste Operations – The construction and demolition waste operations are proposed to be redesigned to increase capacity to accommodate growth in the waste stream and respond to increased diversion mandates; and

Expanded and Redesigned Public Area Operations – The public area operations are proposed to include a public waste tipping area, a material buy-back center, a household hazardous waste drop-off area, a reuse store, and an entrance kiosk with vehicle queuing lanes. The existing public area operations are proposed to be redesigned to increase capacity to accommodate population growth and associated facility use, support customer safety and convenience, and provide opportunities for increased material diversion (e.g., operation of a reuse store).

Complementary/Programmatic Elements are the project elements that are not specifically required to provide continued solid waste management services to Participating Agencies but that are important in achieving other project goals (e.g., create opportunities for innovation and economic growth, enhance opportunities to increase recycling and landfill waste diversion, and enhance ability to comply with regulations). These project elements include the following:

Pilot Study Area – Space would be reserved for third parties to conduct pilot studies using materials and products from the facility and processing them in new ways or producing beneficial products including renewable energy, fuels, and marketable commodities;

Compatible Manufacturing – Space would be reserved for third-party commercial or full-scale compatible technologies and manufacturing operations that would take materials and products from the facility and then produce beneficial products including renewable energy, fuels, and marketable commodities;

University Research Area – Space would be reserved for university-led research using materials and products from the facility and processing them in new ways or producing beneficial products including renewable energy and marketable commodities. This could also include more general solid waste-related research to improve facility diversion, increase efficiencies, lower environmental impacts, etc.; and

Landfill Gas (LFG) to Compressed Natural Gas (CNG) Area – Space would be reserved for a potential third party or WPWMA-led facility that would convert landfill gas to compressed natural gas that could be used to fuel vehicles operated by local governments, waste hauling companies, or other private companies, or otherwise be transferred to other end users.

Supporting Elements are the project elements that are required to support both the solid waste project and complementary/programmatic elements. These include recovered materials storage areas, stormwater ponds, road crossings, maintenance areas, administrative buildings, parking areas, continued use of the existing MRF, a Household Hazardous Waste Facility (HHWF), and redesigned site entrances.

Solid waste project elements and supporting elements include those directly under WPWMA’s control. These elements will be evaluated at a project-specific level of detail in the EIR. Complementary/programmatic elements include those that may involve third-party involvement and are not fully defined at this time. Complementary/programmatic elements will be evaluated at a program level in the EIR.

1 United States Environmental Protection Agency (EPA) Resource Recovery and Conservation Act (RCRA) Subtitle D was promulgated in 1993 and

was implemented by states to address non-hazardous solid waste disposal, including requirements for the liners of municipal solid waste landfills.

PLAN CONCEPT 1

Plan Concept 1 is illustrated in Figure 4 and includes all of the above described elements. The following describes how these elements are proposed to be located on the project site.

Expanded Landfill Capacity – The expanded landfill area would be located on the eastern property, adjacent to the existing landfill, which would allow the expanded landfill to be directly connected to and build upon the existing landfill. Doing so will allow the WPWMA to best utilize available land by achieving additional landfill capacity on the smallest footprint practicable. By expanding the landfill’s footprint to the east, the landfill’s proposed peak elevation would increase to 325 feet, or approximately 30 feet above the currently permitted peak elevation of 295 feet and 129 feet above the landfill’s existing height of 196 feet (as of aerial mapping dated Jan 2, 2019). The eastern landfill expansion, when combined with the proposed excavation of the closed portions of the existing landfill, would result in the site’s total waste disposal capacity approximately doubling.

Existing Solid Waste Excavation – The northern closed and pre-Subtitle D-lined portions of the existing landfill are proposed to be excavated and relocated to a Subtitle D-compliant lined module to provide greater groundwater protection. This relocation of waste would also provide additional landfill disposal capacity within the excavation area.

Expanded and Redesigned Compost Operations – Composting operations and other organics management would be located on the western property. The composting system operations would be sized to accommodate anticipated material growth rates. Placement on the western property provides additional space, specifically allowing for expansion of composting operations as necessitated by current and anticipated future organics regulations.

Expanded and Redesigned Construction and Demolition Waste Operations – Expanded construction and demolition waste operations and ongoing MRF operations would remain adjacent to each other on the center property.

Expanded and Redesigned Public Waste Drop-Off Area Operations – The expanded public waste drop-off area would be located on the western parcel to enhance the safety and convenience of public customers by separating them from the more active commercial waste management operations.

Complementary/Programmatic Elements – The complementary/programmatic elements include compatible manufacturing, pilot study areas, university research areas, and a landfill gas to compressed natural gas area. For the compatible manufacturing and university research uses, areas have been designated in the northern and southern portions of the western property. For potential pilot studies, they are proposed to be located in these same two areas in addition to an area directly east of the MRF operations on the center property. The final element, the landfill gas to compressed natural gas area, is proposed to be located in the southern portion of the western property. Although space has been initially reserved for these elements primarily within the western property, opportunities may arise that would support locating some of these complementary/programmatic elements in closer proximity to the solid waste project elements or within areas not yet developed with solid waste project elements. Therefore, this plan concept assumes these complementary/programmatic elements could be located throughout the project site.

Supporting Elements – The supporting elements for this plan are primarily located in the northern portion of the center property where the majority of supporting activities currently occur. These elements include recovered materials storage areas, maintenance areas, administration buildings, facility parking, the existing MRF, the HHWF, and the existing landfill gas-to-energy plant. Within this area, the existing waste delivery entrance on Athens Avenue is proposed to be realigned to better accommodate anticipated future traffic loading. In addition, a new site entrance is proposed near the southwest corner of Athens Avenue and Fiddyment Road to provide vehicle access to the western property. Further south on Fiddyment Road, a new road crossing would be installed, consisting of either a tunnel, bridge, or conveyor system, to connect the waste operations on the center property to those proposed on the western property. Stormwater ponds are proposed to be located in multiple locations to capture stormwater runoff from site operations, including at the southern end of the eastern property, at the southwestern end of the center property, and within the central area of the western property. In addition to being located within the northern area of the center property, a maintenance area would be located in the central portion of the western property to support composting and public tipping operations. A HHWF may also be located in the public waste drop-off area on the western property to reduce the need for transport of hazardous waste received at the public waste drop-off area to the HHWF located on the center property.

PLAN CONCEPT 2

Plan Concept 2 is illustrated in Figure 5 and includes all of the above described elements. The following describes how these elements are proposed to be located on the project site.

Expanded Landfill Capacity – The expanded landfill area would be located entirely on the western property, separated from the existing landfill by Fiddyment Road. Plan Concept 2 provides less landfill capacity than Plan Concept 1 due to the inability to combine the two landfill footprints. Within the center property, the landfill’s peak elevation would not exceed 295 feet, the current permitted elevation, which is 99 feet greater than the landfill’s existing height of 196 feet (as of aerial mapping dated Jan 2, 2019). The proposed height of the landfill expansion area on the western property would be 325 feet.

Existing Solid Waste Excavation – The northern closed and pre-Subtitle D-lined portions of the existing landfill are proposed to be excavated and relocated to a Subtitle D-compliant lined module to provide greater groundwater protection. The relocation would facilitate expansion of processing and recycling operations in the northern portion of the center property.

Expanded and Redesigned Compost Operations – Composting operations and other organics management would be located in the northern portion of the center property. The composting operations would be sized to accommodate anticipated material growth rates. The relocation of waste from the northern portion of the existing landfill would provide the additional space needed to accommodate these operations.

Expanded and Redesigned Construction and Demolition Waste Operations – Expanded construction and demolition waste operations would be located within the northern portion of the center property near the redesigned composting and public waste drop-off areas.

Expanded and Redesigned Public Waste Drop-Off Area Operations – The expanded public waste drop-off area would be located within the northern portion of the center property near the redesigned composting and construction and demolition waste operation areas. These operations would be designed to ensure they are

separated from the other waste management operations to ensure the safety and convenience of public customers accessing the site.

Complementary/Programmatic Elements – The complementary/programmatic elements include compatible manufacturing, pilot study areas, university research areas, and a landfill gas to compressed natural gas area. For the compatible manufacturing uses, areas have been designated in the southern portions of the western property and on the entire eastern property. The same area in the southern portion of the western property would also be designated for university research uses. Areas for pilot studies and a landfill gas to compressed natural gas facility are designated in the northeastern portion of the center property. Although space has been initially reserved for these elements primarily within the southern portions of the western property and on the eastern property, opportunities may arise that would support locating some of these complementary/programmatic elements in closer proximity to the solid waste project elements or within areas not yet developed with solid waste project elements. Therefore, this plan concept assumes these complementary/programmatic elements could be located throughout the project site.

Supporting Elements – Similar to Plan Concept 1, the supporting elements for this plan are primarily located in the northern portion of the center property where the majority of supporting activities currently occur. These elements include recovery materials storage areas, administration buildings, facility parking, the existing MRF, the HHWF, and the existing landfill gas-to-energy plant. Within this area, the existing waste delivery entrance on Athens Avenue is proposed to be realigned to better accommodate waste deliveries. In addition, a new site entrance is proposed to be installed near the southwest corner of Athens Avenue and Fiddyment Road to provide vehicle access to the western property. The new road crossing identified in Plan Concept 1 on Fiddyment Road would be installed further north near the southern end of the MRF. This new road crossing would consist of either a tunnel, bridge, or conveyor system to connect the waste operations on the center property to those proposed on the western property. Stormwater ponds are proposed to be located in two locations to capture stormwater runoff from site operations, including at the northern end of the western property and at the southwestern end of the center property. A maintenance area is proposed to be located in the northern portion of the western property, directly east of the new landfill footprint on this property to support landfill-related operations.

POTENTIAL ENVIRONMENTAL IMPACTS

The environmental issues to be addressed in the Draft EIR are anticipated to include the following:

Aesthetics Air Quality and Odors

Biological Resources Cultural and Tribal Resources

Geology, Soils, and Paleontology Greenhouse Gas Emissions and Climate Change

Hazards, Hazardous Materials, and Wildfire Hydrology and Water Quality

Land Use and Planning Noise

Public Services Transportation/Traffic

Utilities and Energy

Other CEQA Sections, including alternatives, growth-inducing impacts, and cumulative Impacts

Aesthetics

The project site is located within a relatively flat area at the base of the Sierra Nevada foothills. The existing Western Regional Sanitary Landfill is a prominent visual feature in the area and changes to the landfill and associated solid waste management operations anticipated with project implementation could alter the site’s existing visual character.

Air Quality and Odors

During construction of individual project elements, criteria air pollutant emissions would be temporarily and intermittently generated. Operation of the proposed project would result in air pollutant emissions from a variety of solid waste management operations and from vehicle trips generated by the project. Construction- and

operations-related emissions could adversely affect residences and businesses in the vicinity and contribute to regional emissions. Based on previous studies conducted by the WPWMA2, the dominant odor generating sources at the WPWMA’s facilities include composting, daily landfill disposal operations, and fugitive emissions of landfill gas. Implementation of the proposed project could alter the source potential, intensity, and frequency of site odors. Furthermore, excavation and relocation of waste from the closed area of the existing landfill has the potential to generate odors.

Biological Resources

Special-status plant or wildlife species could potentially occur on the project site. Implementation of the proposed project could result in disturbance or take of special- status species or disturbance or removal of suitable habitat for these species. Aquatic features identified in the project area include vernal pools, swales, seasonal wetlands, and ponds. The project could potentially remove, fill, or hydrologically interrupt wetlands identified on the project site and could potentially affect jurisdictional waters.

Cultural and Tribal Resources

Although no known prehistoric or historic resources have been identified on the project site, excavation activities necessary to construct individual project elements have the potential to disturb unknown archaeological or tribal cultural resources.

Geology, Soils, and Paleontology

The project site is situated in a relatively stable geologic province. However, soil disturbance activities associated with individual project elements could increase soil erosion or affect soil stability. Landfill expansion activities have the potential to affect seismic instability. Also, excavation activities have the potential to expose unknown paleontological resources.

Greenhouse Gas Emissions and Climate Change

Greenhouse gas (GHG) emissions are anticipated to be generated by individual project elements during construction and operations. Emissions would be associated with vehicle trips, on-site equipment usage, increased energy demand, and ongoing and expanded solid waste operations.

Hazards, Hazardous Materials, and Wildfire

The anticipated construction activities and expanded solid waste operations proposed at the site have the potential to increase the transport, use, and storage of hazardous materials that could represent a risk to the public. In addition, the complementary/programmatic elements could introduce new uses that could increase the exposure of the public to hazards or hazardous materials. With the proposed project’s expanded uses at the site, the potential for wildfire could also increase.

Hydrology and Water Quality

Expansion of the solid waste management operations and the introduction of complementary/programmatic elements would alter the site’s hydrology and could affect the quality of the water discharged from the site. Also, proposed waste excavation of the pre-Subtitle D landfill modules could affect site water quality related to rain events during excavation and relocation.

Land Use and Planning

The proposed project would alter land uses on the eastern and western properties that will be evaluated in the context of the policies included in the Placer County General Plan and the proposed Sunset Area Plan. The proposed Sunset Area Plan includes a variety of policies that are anticipated to contribute to long-term growth in

the region. One such policy includes reducing the 1-mile residential buffer that currently exists around the WPWMA facility.

Noise

The construction of the individual project elements, the expansion of solid waste management operations, and the introduction of complementary/programmatic elements would increase noise generation and introduce new noise sources at the site that could affect local residents and businesses.

Public Services

Project implementation, including the introduction of complementary/programmatic elements, could increase the demands on local fire protection, law enforcement, schools, recreational facilities, and road maintenance services.

Transportation/Traffic

The construction of the individual project elements, the expansion of solid waste management operations, and the introduction of complementary/programmatic elements would be expected to increase vehicle trips on local roadways associated with new passenger vehicle and truck haul trips. Also, changes in site entrances could alter traffic patterns immediately adjacent to the site.

Utilities and Energy

Construction of the individual project elements, the expansion of solid waste management operations, and the introduction of complementary/programmatic elements would increase the demand on site utilities including water supply, wastewater services, and solid waste disposal. In addition, the project’s increased energy demands would increase the use of electricity at the site.

Cumulative Impacts

Implementation of the proposed project could potentially result in significant impacts to the above resource areas. When taken together with the effects of past projects, other current projects, and probable future projects, most notably those associated with the proposed Sunset Area Plan and Placer Ranch Specific Plan, the project’s contribution to the overall cumulative effect of all these activities could be considerable.

ALTERNATIVES TO BE EVALUATED IN THE EIR

In accordance with the State CEQA Guidelines (14 CCR Section 15126.6), the EIR will describe a range of reasonable alternatives to the proposed project that are capable of meeting most of the project’s objectives, and that would avoid or substantially lessen any of the significant effects of the project. The EIR will also identify any alternatives that were considered but rejected by the lead agency as infeasible and briefly explain the reasons why. The EIR will provide an analysis of the No-Project Alternative and will also identify the environmentally superior alternative.
