APPROVE OTHER RECOMMENDATION OF CNTY ADMINISTRATOR RECOMMENDATION OF BOARD COMMITTEE Action of Board On: 04/29/2014 APPROVED AS RECOMMENDED OTHER Clerks Notes: VOTE OF SUPERVISORS Contact: Deidra Dingman (925) 674-7203 I hereby certify that this is a true and correct copy of an action taken and entered on the minutes of the Board of Supervisors on the date shown. ATTESTED: April 29, 2014 David Twa, County Administrator and Clerk of the Board of Supervisors By: , Deputy cc: C. 68 To:Board of Supervisors From:Catherine Kutsuris, Conservation and Development Director Date:April 29, 2014 Contra Costa County Subject:Status Report for Keller Canyon Landfill Land Use Permit Review Process BACKGROUND: The Board of Supervisors considered matters related to the Keller Canyon Landfill at their meeting on February 25, 2014. At that time, Department of Conservation and Development ( DCD) staff was directed to return to the Board on April 29, 2014 to present specific information about the landfill and the associated land use permit. The Board requested that staff provide additional information to fully address any issues related to the Keller Canyon Landfill raised in correspondece to the Board that had not been included in the report dated February 25, 2014 due to time limitations. The Board also asked staff for a status report on the review process for the Keller Canyon Landfill Land Use Permit. This report provides the information requested related to both subjects which is organized in two distinct sections. Section I provides further information on the issues that were not fully addressed in the report presented to the Board on February 25th. Section II provides the requested status of the permit review, which staff expects to complete by the end of August 2014. The details staff has provided in this report and the associated Attachments is based on the information and evidence currently available. Staff has and will continue to investigate any areas of potential concern as they arise as part of the permit review process and our ongoing monitoring and enforcement responsibilities. I. RESPONSES TO OUTSTANDING ISSUES RAISED IN FEBRUARY 2014 Wilson Wendt of Miller, Starr & Regalia law office, representing Mt. Diablo Recology, submitted three letters addressed to the Board of Supervisors dated February 11, 2014, February 18, 2014 and February 25, 2014. Only one of the letters was received in time to be addressed in the February 25th Board Order, therefore staff was unable to include responses to new issues raised in the last two letters. In order to fully respond to all of the issues raised as a part of this report, staff had to provide a substantial amount of information. A summary of staff’s conclusions is provided below. However in order to limit the length of this report, the detailed information substantiating these conclusions is contained in Attachments C – F. FEBRUARY 11TH LETTER FROM MILLER, STARR AND REGALIA As directed by the Board, staff reviewed and analyzed the issues not fully addressed in the February 25th report. Staff’s conclusions regarding the four applicable issues are summarized below and further explained in the attachments. 1. Alleged Violation of Anti-Trust and Unfair Competition Laws – Other agencies have the designated enforcement authority for these state and federal laws. Therefore, it is not appropriate for the County to weigh in on allegations that anti-trust and unfair competition laws have been violated by Republic Services (Keller Canyon Landfill). (See Attachment C for further information.) 2. Alleged Violation of Land Use Permit Condition 5.1 – Republic Services’ proposed Keller Canyon Landfill disposal rate submitted to the CCCSWA is within the range of current rates being charged, therefore the proposed amount does not constitute a refusal to accept in-County waste for an appropriate rate. (See Attachment C for further information.) 3. Alleged Violations & Inquiries about multiple Land Use Permit Conditions – Explanations responsive to the requests pertaining to specified Conditions are provided, as are conclusions related to each alleged Land Use Permit violation. In summary, none of the circumstances cited adequately substantiate conclusions that the specified violations occurred. (See Attachment D for further information.) 4. Alleged Violations & Requests specific to the CCCSWA’s Franchise– The CCCSWA is responsible for enforcing their own Franchise Agreement, therefore it is not appropriate for the County to investigate compliance with the CCCSWA’s Franchise Agreement. (See Attachment C for further information.) FEBRUARY 18TH LETTER FROM MILLER, STARR AND REGALIA Wilson Wendt’s letter dated February 18, 2014 identifies concerns specific to the alleged issue involving the potential improper acceptance and use of green waste as Alternative Daily Cover (ADC). 1. ADC: Tonnage Reporting - Contra Costa County submits ADC tonnage reports to CalRecycle based upon the quarterly data provided by the active in-county landfills, including Keller Canyon Landfill. Therefore, that is the most appropriate source of data upon which to base any conclusions with respect to compliance with any applicable regulations. (See Attachment E for further information.) 2. ADC: Proper Handling & Use – Keller Canyon Landfill’s operations have been found in compliance with respect to handling and use of ADC based on the results of all but one of their unannounced inspections conducted by the two regulatory agencies responsible for enforcing the ADC requirements (County Environmental Health and CalRecycle). (See Attachment E for further information.) 3. ADC: Payment of Fees – Neither of the applicable enforcement agencies have made a determination that any of the ADC material used at Keller should be treated as disposal. In the absence of a determination that the green waste used as ADC should be reclassified as disposal, there is nothing to substantiate that the conclusion that the County has not been paid the total amount of fees (surcharge) due for this material. (See Attachment E for further information.) FEBRUARY 25TH LETTER FROM MILLER, STARR AND REGALIA Although the letter dated February 25th was submitted the day of the Board meeting, in most cases the responses are similar to those previously identified above. The majority of the letter focuses on concerns about improper acceptance and use of green waste and construction & demolition debris initially raised in the February 18th letter. 1. Fees Alleged to be Due - The information presented does not change the conclusion identified in response to this issue raised in the letter dated February 18th, therefore staff has no basis to substantiate the allegation that the County has not been paid the total amount of fees (surcharge) due for green waste classified as ADC. (See Attachment F for further information.) 2. Direct Haul Violates Solid Waste Facility Permit – The permit requirement cited in the letter only applies to “municipal solid waste” (MSW), therefore whether or not ADC or other non-MSW is direct hauled to the landfill has no bearing on the status of compliance with this requirement. (See Attachment F for further information.) 3. Reports Requested in February 11th Letter – The only report generated by or for the County which was requested in Mr. Wilson’s letter dated February 11th is the Implementation & Mitigation Monitoring Program (copy provided as Attachment G), the remaining reports cited pertain to requirements in the CCCSWA franchise and therefore beyond the County’s purview. (See Attachment F for further information.) 4. Notices of Violations Noted in Prior Letter(s) – Most violations cited were addressed in the February 25th report to the Board, with the exception of air quality enforcement actions that occurred in 2009 and 2010. There is no evidence of continued or ongoing violations that warrant further action by the County at this time. (See Attachment F for further information.) II. KELLER CANYON LANDFILL LAND USE PERMIT County Code Chapter 418-4 requires disposal facilities to obtain a permit approved by the Board of Supervisors. Keller’s Land Use Permit serves as the permit required under County Code Chapter 418-4. The Land Use Permit (LUP 2020-89) allowing the development and operation of the Keller Canyon Landfill (KCL) was approved by the Board of Supervisors on July 24, 1990 and the landfill opened in May of 1992. The Land Use Permit was subsequently amended by the Board on November 1, 1994 adding a new (replacement) Mitigation Fee condition. Additional conditions governing the construction and operation of a landfill gas power plant were added to the Land Use Permit when the second amendment was approved by the Board on June 25, 2002. The LUP conditions of approval are intended to mitigate potential on-site and off-site environmental impacts of landfill design and operations. Some of these conditions of approval were the result of impacts/mitigations contained in the Environmental Impact Report (EIR) prepared for Keller Canyon Landfill in 1990. Additionally, other conditions of approval were developed as part of Board of Supervisors special conditions of approval, County Code requirements and regulatory requirements enforced by other agencies. The LUP contains over 280 conditions of approval which are organized into 36 sections (see Attachment A). It is important to note that only a fraction of the over 280 conditions in Keller Canyon Landfill’s LUP apply to ongoing operations, which narrows the scope of the applicable regulatory agencies’ respective monitoring and enforcement responsibilities. The majority of Keller’s LUP Conditions do not require on-going monitoring by DCD. There are a wide range of reasons that DCD does not need to monitor compliance for certain LUP conditions, including but not limited to: Condition being administrative in nature Condition was satisfied prior to the landfill opening Condition is inconsistent with governing laws or court decisions Condition solely cross-references another LUP condition Condition mirrors requirements already enforced by other agencies BOARD OF SUPERVISORS INVOLVEMENT DURING THE FIRST THREE YEARS OF OPERATIONS A wide range of issues were presented, considered and/or addressed at numerous Board meetings during the first few years of its operation, including consideration of the new and modified conditions recommended for consideration in 1994. Several of the most important hearings are noted below. April 28, 1992: Keller began accepting waste in early May 1992. Roughly one week prior to the landfill’s opening, the Board received a report about Keller Canyon Landfill’s Land Use Permit to acknowledge certain Conditions had been satisfied and provide the status and plans for implementing the remaining LUP Conditions which are not pre-requisites to the opening of the landfill. September - November 1994: A number of new or modified conditions were recommended to the Board of Supervisors by staff and the County Planning Commission as a part of Amendment 1 to Keller Canyon Landfill's Land Use Permit in 1994 (see Attachment I). The Board elected not to approve the majority of the changes to the conditions at that time, with the exception of adding a new Condition 35.8 which replaced the mitigation fee requirements in Conditions 35.1 & 35.3. June 1995: In 1995, the Board provided direction about criteria to be used for Keller’s Land Use Permit Conditions (see Attachment B). According to the approved “Criteria Review”, the Board requested staff to a) refer Keller’s Land Use Permit Conditions of Approval to the County Planning Commission for review, pursuant to the Board’s review criteria, and b) prepare a staff report for consideration by the County Planning Commission. PERMIT REVIEW CONDITION At the time this Land Use Permit was being considered for approval in 1990, there were substantial concerns and uncertainty associated with the siting and operation of a landfill in the context of evolving regulatory requirements. Board actions related to the landfill project were subject to a great deal of public scrutiny and opposition. The County attempted to address as many concerns as possible when crafting the Land Use Permit Conditions of Approval. One such example is the LUP Condition requiring regular public hearings during the initial phase of landfill operations, so that the Board of Supervisors would have the opportunity to adapt requirements If needed based on actual operating conditions. Condition 11.1 states the following: “The Board of Supervisors will hold annual public hearings to review the Conditions of Approval for this Land Use Permit for three years beginning one year after the commencement of operations of the Landfill. The Board may refer proposed changes to the Land Use Permit to the County Planning Commission for processing. Thereafter, the County Planning Commission shall hold public hearings on the Land Use Permit at three-year intervals. As a result of a review and public hearing, the County Planning Commission may recommend to the Board of Supervisors new or modified conditions to improve the public health, safety, and welfare. Nothing in this condition shall preclude the Landfill owner from applying for amendments to the Land Use Permit at any time or preclude the County from addressing emergency situations or new requirements imposed by State or Federal legislation or the courts.” Unlike the permit review conditions contained in more recent LUPs, the periodic permit review hearings for the Keller Canyon Landfill are not intended to address status of LUP compliance; but rather to provide the Board of Supervisors and/or County Planning Commission the opportunity to review the LUP Conditions of Approval in order to determine if any new or modified conditions are needed to improve the public health, safety, and welfare. Any new or modified conditions identified by the Planning Commission are to be considered recommendations subject to the Board of Supervisors approval. PERMIT REVIEW CRITERIA ADOPTED BY THE BOARD IN 1995 The Permit Review Criteria approved by the Board in 1995 is divided into two parts (see Attachment B). Part 1 includes background research to be conducted by staff in advance of the hearing. Part 1 also provides context related to the permit review authority, intent/context, status of the mitigation monitoring program and other matters. Part 2 outlines the criteria for the actual permit review hearing before the County Planning Commission. Part 2 also specifies the only five circumstances which would allow the County to impose new or modified conditions, which are as follows: 1) new regulations, 2) court decisions, 3) significant health impacts, 4) significant safety impacts or 5) significant welfare impacts. STATUS OF THE CURRENT PERMIT REVIEW PROCESS Subsequent to the February 25, 2014 hearing, DCD staff has taken several steps to proceed with the Board’s request in order to ensure timely progress on the permit review. Staff has conducted several meetings, including conference calls, with Keller representatives and conferred with the Environmental Health Division. Keller Canyon Landfill has confirmed that their preliminary report of condition will be submitted shortly. County staff is confident that Permit Review will be ready to go to hearing within the 6-month period prescribed by the Board. Staff is planning to prepare a staff report for review and consideration by the County Planning Commission at a public hearing to be held no later than the end of Summer 2014. Once the County Planning Commission has had an opportunity to consider Keller’s Permit Review, any recommended changes to the conditions would be subject to final approval by the Board of Supervisors. ADDRESSING PAST & FUTURE CHANGES IN THE REGULATORY & PERMITTING FRAMEWORK Certain Land Use Permit conditions of approval were drafted to mirror requirements specified in various laws. Some of these laws have been revised, replaced or repealed in the intervening decades since the 1990 approval. Numerous of these regulatory requirements have since been incorporated into the permits enforced by County Environmental Health as well as regional and state agencies. There are also many areas of overlap with permits issued by other agencies that regulate Keller Canyon Landfill. Generally, DCD defers to other permitting or regulatory agency oversight and determinations on matters for which they have primary jurisdictional authority and responsibility, consistent with LUP Condition 11.11. The County anticipated the need to retain some flexibility to adapt Keller Canyon Landfill’s LUP to changing requirements as is evidenced in Condition 11.11. Condition 11.11 states the following: “Several of these Conditions of Approval relate, paraphrase or summarize laws and regulations which are imposed and enforced by other governmental agencies which have jurisdiction over particular aspects of this project. It is this Board's intent in adopting these Conditions of Approval to provide the applicant and the public with an overview of the scope of regulation applicable to this project and to provide this County with enforcement power if such laws and regulations enforced by other agencies are violated. Unless specifically stated in the Conditions of Approval, however, it is not this Board's intent to establish rules or regulations which are stricter than the laws or regulations which are applied to this project by the other agencies with jurisdiction over aspects of this project. If another agency primarily responsible for some aspect of this project finds that any action or inaction is in compliance with, or violates, any such law or regulation, that finding shall be conclusive. If these Conditions of Approval require some approval by any other agency and that agency declines to approve or disapprove the subject matter, such approval shall be deemed to have been given for purposes of these Conditions of Approval.” The County is not obligated to officially modify local permit conditions in response to changes in regulations enforced by other agencies. Consistent with the intent of Condition 11.11, the implementation of the LUP is adapted administratively when deemed necessary in order to respond to changing requirements imposed by State or Federal legislation as well as the courts. ONGOING MONITORING OF LUP IMPLEMENTATION AND COMPLIANCE DCD staff evaluated compliance of each condition required to be met prior to construction and operation of the Keller Canyon Landfill during the final development plan process. DCD, Environmental Health, acting as the Local Enforcement Agency, and the RWQCB have ongoing roles in reviewing and approving various aspects of the Keller facility, including but not limited to, operational matters and requests to construct the liner and underdrain system for each new waste cell proposed as individual phases. DCD and Environmental Health respond to complaints associated with the applicable landfill requirements if/when they are received. Environmental Health acts as the enforcement lead to help assure permit compliance, consistent with County Code Section 418-4.018. DCD primarily relies on County Environmental Health for operational compliance issues, a key element of monitoring landfill operations compliance involves conducting unannounced inspections which occurs on a monthly basis. DCD’s monitoring of Keller Canyon Landfill’s LUP compliance predominantly addresses requirements that are either: triggered by a one-time or periodic action or event, including requests/proposals submitted by the operator (e.g. proposed construction of the next waste cell within the permitted footprint which is being constructed in phases as provided for in the LUP conditions), or non-operational matters that primarily involve submittals/documentation, some of which relate to or supplement provisions in Keller’s Franchise Agreement (e.g. fees, reporting, etc.) DCD staff has elected to proactively monitor Keller Canyon Landfill operations on a routine basis for two specific nuisances even though it is not required to do so because the associated requirements overlap those enforced by Environmental Health or the Air District. DCD established the additional routine monitoring that is now in place in 2009, following several problematic odor and litter incidents that had occurred between 2006-2008. Specifically, DCD's Code Enforcement staff conducts routine (unannounced) site visits in the vicinity of the landfill to ensure the landfill is being operated in compliance with the LUP conditions pertaining to litter and odor. The frequency of these site visits varies based on determined need. During each site visit, the DCD inspector: confirms whether or not the facility can be smelled off-site from the facility gate (Condition 20.2) confirms whether accumulated litter is being removed within the required frequency from West Leland Road to about 500 feet south of the site (Condition 25.8) Since the routine monitoring process was put in place in 2009, DCD has not identified any odor or litter incidents warranting issuance of any additional notices of violation. DCD is also working with Keller Canyon Landfill to formalize a cost effective annual reporting process to ensure compliance status is routinely documented in the future. This annual reporting process is being designed to help institutionalize a system that fosters ongoing accountability. CONSEQUENCE OF NEGATIVE ACTION: Should the Board not accept the status report about the Keller Canyon Landfill Land Use Permit review process, Should the Board not accept the status report about the Keller Canyon Landfill Land Use Permit review process, County staff would proceed with completing the Permit Review process consistent with the Board approved Permit Review Criteria unless the Board directs otherwise.

VALIDITY PERIOD 4.1 Validity Period. The Landfill developer shall install pre-requisite improvements and open the Landfill for receiving refuse within three years of the final approval of the project's Solid Waste Facilities Permit. This validity period shall be tolled while any appeal filed by parties other than the Landfill developer is pending. The Landfill developer may request from the Director of Community Development one or more one-year extensions of the Land Use Permit. If the Land Use Permit is not implemented within the specified time, it shall become null and void. The Director of Community Page 11 Development may allow each one-year extension if the Director finds that there are changed circumstances which warrant the consideration of changes to the Conditions of Approval. 4.2 Operative Date. This Land Use Permit is valid upon approval by the Board of Supervisors. However, it shall not become operative until and unless the permittee (landfill owner, etc.) first obtains and the Board of Supervisors grants a franchise to or approves an agreement with permittee (see Section 13, Franchise Agreements). 5. SERVICE AREA 5.1 Area of Origin. The area of origin of all waste hauling vehicles admitted to the landfill, shall be Contra Costa County. The Landfill operator shall not refuse to receive eligible wastes which originate in Contra Costa County provided such wastes are delivered to the facility in accordance with these Conditions of Approval and the landfill's Solid Waste Facilities Permit, and provided that appropriate disposal fees are paid. 5.2 Out-of-County Wastes. The Landfill operator shall not receive wastes from outside Contra Costa County unless such imports of waste are specifically approved by the Board of Supervisors. This condition shall not apply to wastes which may be temporarily received under the Emergency Use provisions of Condition 6.5 or the Reciprocal Capacity Agreement of Condition 5.4. 5.3 Sub-County Service Area. If there is more than one Class II or Class III landfills operating in Contra Costa County, the Board of Supervisors may establish sub-County service areas for each on a temporary or long-term basis. If the Board has established a sub-County service area for the Landfill, the operator shall not accept waste for disposal from outside such area. 5.4 Reciprocal Capacity Agreement. The Landfill operator shall receive waste from outside Contra Costa County if in accordance with the terms and conditions of a Reciprocal Capacity Agreement entered into by Contra Costa County with another county. Waste shall be received upon reasonable notice to the Landfill operator and the Board of Supervisors and direction by the Board to the Landfill operator as to the terms and conditions under which the waste will be received. The Board may specify disposal charges which are applicable only to the waste received under the Reciprocal Capacity Agreement. 5.5 Pre-Requisite Curbside Recycling Program. The Landfill shall not admit or dispose of waste loads from communities which do not have in operation a Page 12 curbside recycling, or equivalent, program approved by the Board of Supervisors. Board of Supervisors approval may be interpreted as a consistency with a Board of Supervisors-approved Countywide Integrated Waste Management Plan.

The wastes shall originate in Contra Costa County. f) Other specialized waste transport trucks, hauling wastes originating in Contra Costa County and identified in the Landfill's Solid Waste Facilities Permit. 8.2 Service Area Restriction. See Section 5. 8.3 Emergency Exemption. See Condition 6.5. 8.4 Reciprocal Use Exemption. See Condition 5.4. 9. OPERATING PARAMETERS 9.1 Hours of Operation. The Landfill operator shall not open the landfill to receive waste loads before 7:00 a.m. or after 7:30 p.m. Refuse shall be covered by 7:30 p.m. at which time working lights shall be extinguished. Entry and security lights shall be dimmed at 7:30 p.m. Other hours of operation, within those parameters, may be specified by the County Health Services Department in the Landfill's Solid Waste Facilities Permit. Special loads may be received at other times in accordance with procedures established by the County Health Services Department. The Director of Community Development may administratively shorten or extend the hours of operations prescribed above after consultation with the Landfill operator, the County Health Services Department, and the Local Advisory Committee, after holding a public hearing to obtain the comments of other interested parties. To shorten the hours of operation, the Director of Community Development shall find that the changes are needed to mitigate substantial noise, traffic, or similar impacts arising from the operation of the Landfill which were not known when this Land Use Permit was adopted. To extend the hours of operation, the Director of Community Development shall find that longer hours will not cause traffic, noise, glare, Page 15 or similar impacts of Landfill operations to substantially increase in the vicinity of the Landfill. 9.2 Operating Days: The landfill shall remain open for operation six days a week. It shall close on Sundays. 9.3 Maximum Daily Tonnage. The landfill may accept for disposal a maximum of 3,500 tons of refuse per day through the year 2005. The Board of Supervisors shall review and revise, if necessary, the maximum allowable tonnages per day, prior to the year 2005. If the Board establishes sub- County service areas, maximum tonnages for each landfill shall be prorated to reflect their service areas. The Board may increase the maximum daily tonnages, if necessary, to reflect Reciprocal Capacity Agreements or emergency measures. 9.4 Minimum Buffer Zone. The Landfill developer shall reserve a minimum buffer of 2,000 feet from the closest place of permanent waste placement to the closest existing residence on Jacqueline Drive. 9.5 Special Buffer Area. No residential housing shall be permitted at any time in the special buffer area. See Condition 23.2. 9.6 Dedication of Special Buffer Area. At the time of the submission of the landfill's Development and Improvement Plan, pursuant to Government Code Section 7050, the landfill owner shall offer to dedicate the fee title of the land within the Special Buffer Area to the County of Contra Costa for recordation. The County may accept the fee title and complete the dedication subsequent to the opening of the landfill for the disposal of waste. In making the offer of dedication the Landfill owner may reserve the rights to carry out mitigation programs required by these Land Use Permit Conditions of Approval, and as may be further detailed in implementation plans required to be prepared by these Conditions within the Special Buffer Area. The Landfill operator may perform grading and make installations, such as drainage ditches within the Special Buffer Area related to the landfill facility, provided that the grading and installations are consistent with the approved final Development and Improvements Plan and do not impair the capability of the Area to accommodate agricultural grazing and provide habitat mitigation consistent with these Conditions of Approval. Similarly, the Landfill operator shall be allowed to carry out closure and post-closure activities related to the landfill or the Special Buffer Area provided that such activities are consistent with a County-approved closure plan and with the uses of the land allowed by these Conditions of Approval. The County may require the Landfill operator to maintain the Special Buffer Area, subsequent to dedication, at the operator's expense. Maintenance shall include security, weed control, erosion control and the provision of fire Page 16 trails. 10. WASTE MEASUREMENT AND CHARACTERIZATION 10.1 Volume Estimation. The Landfill operator shall submit topographic maps of the landfill and a report of capacity absorption and fill rates to the Community Development Department every two years on the anniversary date of the landfill's opening. The Landfill operator shall also submit an initial topographic map prior to receiving wastes. 10.2 Scales. The Landfill developer shall install certified scale(s) at the landfill to weigh incoming and outgoing trucks. A weighing program, subject to approval by the County Department of Health Services and Director of Weights and Measures, shall be implemented to monitor incoming wastes. 10.3 Waste Characterization. The Landfill operator shall participate with transfer station operators serving the landfill in a program to characterize incoming wastes by type, amount, and originating community and perform detailed load inspections on vehicles according to a program specified by the County Community Development Department and County Health Services Department. Reports shall be submitted to the County on a quarterly basis. 11. ADMINISTRATION 11.1 Permit Review. The Board of Supervisors will hold annual public hearings to review the Conditions of Approval for this Land Use Permit for three years beginning one year after the commencement of operations of the Landfill. The Board may refer proposed changes to the Land Use Permit to the County Planning Commission for processing. Thereafter, the County Planning Commission shall hold public hearings on the Land Use Permit at three-year intervals. As a result of a review and public hearing, the County Planning Commission may recommend to the Board of Supervisors new or modified conditions to improve the public health, safety, and welfare. Nothing in this condition shall preclude the Landfill owner from applying for amendments to the Land Use Permit at any time or preclude the County from addressing emergency situations or new requirements imposed by State or Federal legislation or the courts. 11.2 Local Advisory Committee. The Community Development Department shall organize, and the Landfill developer shall participate in a local advisory committee, consisting of elected representatives of local residents and neighborhood associations, to comment and advise on the development of the landfill and its operations. The Board of Supervisors may sanction the Local Advisory Committee as an official County committee. The committee Page 17 shall be established as soon as reasonably possible after the Board of Supervisors' approval of this Land Use Permit, if such approval is forthcoming. Meetings shall be initiated following the approval of a Land Use Permit and shall be held at least quarterly through the first two years of landfill operation. Subsequently, meetings may be held annually, but with the provision for meetings on call by the chair or the written request of 3 or more members. The County Health Services Department shall be notified at least 10 days in advance of all meetings. Subjects for consideration at meetings will include, but shall not be limited to safety and emergency procedures, landfill fill-related traffic problems, screening of visual impacts and problems of litter, odor, and noise control.

The Landfill operator shall provide reasonable access to the landfill arranged through the Community Development Department. A surcharge on the tipping fee may be used to fund the advisory group's operations. 11.3 Insurance and/or Bonding. The applicant shall provide the insurance and bonds specified by the units of government having approval authority over the project. Subjects will include, but not be limited to, continuity of landfill operation, non-compliance, emergency measures, construction performance, landscaping and closure. 11.4 Notification Program. The Landfill operator shall prepare and implement a program to notify potential users of the landfill of its opening and closing times, and the conditions of its use, including waste reduction and recycling requirements, site access regulations, and a detailed list of prohibited hazardous wastes and alternative disposal options. The program should be prepared in conjunction with the operator(s) of the transfer station(s) serving the landfill. It shall be approved by the County Community Development Department. 11.5 Development Coordinator. The Landfill owner shall provide a fund to support a County Landfill Development Coordinator, if the County establishes the position, through the period of construction and landfill operations. The Coordinator shall be a staff member or a consultant. The owner shall make quarterly advance payments. The Landfill developer and operator shall provide such information as the Development Coordinator may require to review plans and installations under the purview of the County, except that any requirements for additional studies shall be subject to the approval of the County's Director of Community Development. 11.6 Compliance and Mitigation Monitoring Program. The Landfill operator shall provide a fund to support County staff monitoring of compliance with Condi- Page 18 tions of Approval and mitigation monitoring programs, as designed and implemented by the County Community Development and Health Services Departments. 11.7 Pre-Annexation Notification. If the Landfill owner decides to request annexation of the Landfill to a city, the owner shall notify the Board of Supervisors at least 180 days in advance of filing any application for such annexation. The Board may require the Landfill owner to consult with it or County staff to determine how solid waste management programs specified in these Conditions of Approval would be carried out subsequent to annexation. In no case shall the annexation relieve the Landfill operator of the financial responsibilities, including payment to the County of mitigation fees, specified in these Conditions. 11.8 Fee and Surcharge Identification. The Landfill operator (permittee) shall not identify the costs of public agency (County, etc.) fees, charges, or surcharges on bills and receipts issued to landfill users without first obtaining the specific written approval of the County. 11.9 Interpretation of Conditions. The Community Development Department Director is authorized to interpret these Conditions in the event that any clarification is needed. 11.10 Conditions Requiring Franchise. Conditions of Approval Nos. 4.2 and 13.4 require a franchise or agreement to be established by this County. All of these Conditions of Approval shall be subordinate to the terms of said franchise or agreement, and the terms of said franchise or agreement shall control in the case of any conflict. There shall be no need to amend these Conditions of Approval in the event of such a conflict. 11.11 Regulations Enforced by Other Agencies. Several of these Conditions of Approval relate, paraphrase or summarize laws and regulations which are imposed and enforced by other governmental agencies which have jurisdiction over particular aspects of this project. It is this Board's intent in adopting these Conditions of Approval to provide the applicant and the public with an overview of the scope of regulation applicable to this project and to provide this County with enforcement power if such laws and regulations enforced by other agencies are violated. Unless specifically stated in the Conditions of Approval, however, it is not this Board's intent to establish rules or regulations which are stricter than the laws or regulations which are applied to this project by the other agencies with jurisdiction over aspects of this project. If another agency primarily responsible for some aspect of this project finds that any action or inaction is in compliance with, or violates, any such law or regulation, that finding shall be conclusive. If these Conditions of Approval require some approval by any other agency and that agency declines to approve or disapprove the subject matter, such Page 19 approval shall be deemed to have been given for purposes of these Conditions of Approval. 11.12 Required Expenditures. This Board does not intend, by requiring the applicant to fund various measures, to make any decision regarding whether or not, or how, any expenditures incurred may be recovered through the rate structure or otherwise by the applicant. Any such decision by this Board shall be reserved for its consideration in the franchise or agreement. No inference regarding this issue is to be drawn from this Board's use of any particular terminology in these Conditions of Approval. 11.13 Designation of Authority. In any instance where a Condition of Approval provides that this Board will decide or act upon a certain matter, this Board may delegate the initial decision making or action with respect to that matter to the Director of Community Development or such other designee as this Board determines to be appropriate, provided that there shall be a right of appeal to this Board from any decision to the Director of Community Development or other designee. 12. RATE REVIEW 12.1 Rate Approval. The Board of Supervisors shall approve all rates charged by the landfill operator at the landfill. The rates established by the Board will be not only maximum rates but also minimum rates. 12.2 Rate Review. The Board of Supervisors shall review and approve rates annually in accordance with an approved rate application procedure. More frequent review of rates may occur if requested by the landfill operator and if the Board determines that changing circumstances warrant such review. The Board may also review rates more frequently if the Board determines that it is in the public interest to do so. 12.3 Form and Content of Rate Review Application. The landfill operator shall submit its rate application in a form and content as specified by the County. Such application may require the landfill operator to submit the application on forms and/or using computer software provided by or specified by the County.

The compost shall be used for landfill landscaping, cover material or other approved uses. The purpose of the pilot project shall be to determine the feasibility of large- scale on-site composting. The composting operations shall meet the State Department of Health Services' regulations on land application, if applicable. The pilot project shall be in operation within six months of the opening of the Landfill. Its results shall be considered at the second Land Use Permit review. 31.6 Wood Chipping. The Landfill operator shall establish a program to encourage landscape services and construction/demolition material haulers to segregate wood material for chipping. The program shall be approved by the County Community Development Department and shall be placed in operation within six months of the landfill's opening. Page 52 31.7 Methane Recovery. The Landfill operator shall explore the use of methane in landfill gas collected for air pollution reduction as a fuel commodity. The operator shall report findings to the Community Development Department at the time of the landfill's periodic reviews. If there is an economic use found for recovered methane, and if the County subsequently includes the use in its Integrated Waste Management Plan, the Landfill operator shall implement a methane recovery program. 31.8 Equipment Maintenance. The Landfill operator shall maintain motorized landfill equipment to assure maximum fuel efficiency. 31.9 County Resource Recovery Management Program. When directed by the County, the Landfill operator shall impose a tonnage surcharge adequate to support a County Resource Recovery Management Program consisting of the Office of Resource Recovery Management and its program. The cost of the program to be supported by the surcharge shall not exceed $100,000 at 1987 levels. If other solid waste disposal facilities are subject to this or a similar condition, the County may pro-rate the cost of the program among them according to a formula approved by the Board of Supervisors. 31.10 Fund Recovery. The Landfill owner may recover funds provided to the County in advance of the opening of the Landfill through subsequent rate adjustments or surcharges approved by the County. The County may pro- rate the cost of the program among other waste disposal facilities it approves which are subject to similar conditions. 32. CONSTRUCTION ACTIVITIES AND CONDITIONS 32.1 Hours of Construction. The Landfill developer shall restrict outdoor construction activities to the period from 8:00 a.m. to 6:00 p.m. Monday through Saturday. 32.2 Exemption. The Landfill developer may request, in writing, and the Director of Community Development may grant, exemptions to Condition .1 for specific times for cause. An example is the placing of concrete. 32.3 Access Roads. Before commencing landfilling operations, the Landfill developer shall install and pave the site access road from Bailey Road to the Phase I excavation area (see Initial Facilities Site Plan drawing of the Initial Development and Improvements Plan, Condition 16.1). This installation shall include the new bridge over Lawlor Creek and the turnaround lane. An area which can be used by the California Highway Patrol for vehicle inspection/weighing shall also be constructed. Page 53 32.4 Phasing Plan. The Landfill developer shall design a Phasing Plan setting forth a schedule of construction activities and projects, with detailed information provided on sensitive installations such as the landfill liner and the leachate collection and gas management systems. Sensitive installation projects shall be subject to inspection by the Geotechnical Inspector (Condition 23.6). The necessary installations of the Surface Drainage System (Condition 18.2) and Soil Erosion and Control Plan (Condition 18.4) shall be in place before major excavations commence in order to ensure controlled surface water runoff. Sediment in the sedimentation pond shall be monitored to control quality of runoff. Construction activities shall be timed to coincide with the dry season and low surface water flows. 32.5 Unstable areas. Areas determined to be unstable by the Stability Analysis performed for the landfill (condition 18.4) shall be excavated or retaining walls installed under the supervision of a Certified Engineering Geologist or a Registered Geotechnical Engineer. 32.6 Dust Suppression. The developer shall sprinkle or chemically treat graded areas, borrow sites, stock piles, and temporary pavements to control dust, as determined necessary by the County Health Services Department. 33. CLOSURE AND POSTCLOSURE MAINTENANCE 33.1 Submittal of Plan. The Landfill operator shall submit to the San Francisco Regional Water Quality Control Board, the Integrated Waste Management Board, and the County Health Services Department a plan for the closure and the postclosure maintenance of the landfill as required by State law, but no later than upon application for a Solid Waste Facilities Permit. A copy of the closure and postclosure maintenance plan shall be submitted to the County Community Development Department. 33.2 Funding of Closure and Postclosure Maintenance Plan. The Landfill operator shall submit to the Board of Supervisors and California Integrated Waste Management Board evidence of financial ability to provide for the cost of closure and postclosure maintenance in an amount not less than the estimated cost of closure and 15 years of postclosure maintenance as contained in the submitted closure and postclosure maintenance plan. Evidence of financial ability shall be in the form of a trust fund approved by the Board of Supervisors in which funds will be deposited on an annual basis in amounts sufficient to meet closure and postclosure costs when needed or an equivalent financial arrangement acceptable to the Board of Supervisors and the California Integrated Waste Management Board. The Landfill operator shall maintain a trust fund balance that equals or exceeds the requirements of state law or regulation notwithstanding, however, the Page 54 trust fund balance shall be at least equal to the then current closure and postclosure cost estimate at such time the landfill has reached one-half of its permitted capacity. The Trust Fund balance requirement shall be appropriately adjusted if the landfill is closed in stages under Condition 33.4. 33.3 Revision to Plan and Cost Estimates. Should State law or regulation regarding the closure and postclosures maintenance plan or funding of the plan change at any time, the owner of the landfill shall submit any required changes to the closure and postclosure maintenance plan and/or evidence of financial ability to the Board at the same time as submittal to the applicable state or regional agency. 33.4 Staged Closure of the Landfill. The landfill owner or operator shall close the landfill in stages if compatible with the filling sequence and the overall closure plan. 33.5 Use of Landfill Following Closure. After active landfill operations have ceased, the site shall be utilized for grazing purposes. The Board may require the owner of the landfill to deed all development rights for the landfill site to the County to ensure fulfillment of this condition. 33.6 Postclosure Maintenance. The Landfill operator shall institute a postclosure maintenance program to ensure that containment and monitoring facilities retain their integrity. If damaged areas are found, the operator shall notify the County and take remedial actions to prevent odor and landfill gas problems. 34. ABANDONED VEHICLE STORAGE 34.1 Storage Requirement. The Landfill operator shall provide a minimum 10- acre area on the landfill site for the storage of abandoned vehicles awaiting salvaging, if required by the Board of Supervisors. The storage site operator shall accept only vehicles directed to the site by a law enforcement agency operating in Contra Costa County, which shall be responsible for the vehicle until its title is conveyed to a salvager. The site would provide storage only; operations of disposing, salvaging, and security of abandoned vehicles shall not be the responsibility of the operator. The site may be subject to further planning and development approvals, and would be subject to the California Environmental Quality Act. The storage of abandoned vehicles shall be subject to conditions set by the County Health Services Department, and may be subject to the approvals of regulatory agencies having jurisdiction. 34.2 Off-site Storage Option. The Landfill operator may establish the Page 55 abandoned vehicle storage area at another location, which shall be subject to the approval of the County Community Development Department. 35. SPECIAL CONDITIONS OF APPROVAL 35.1 Transportation System Impact Fee. The Landfill operator shall pay to the County of Contra Costa a Transportation Impact Fee of $2.00 per ton of waste received at the Landfill to mitigate the general impacts of the Landfill- generated traffic on the County's road system. The operator shall deposit the fee monies quarterly in a segregated account established by the County. The fee shall be considered to be a pass-through business cost for the purposes of rate setting. The fee shall be adjusted annually to reflect the current Consumer Price Index. The Board of Supervisors approved Amendment 1 to Land Use Permit 2020-89 on November 1, 1994 which stayed the operation of Conditions 35.1 and 35.2 as long as the new Condition 35.8 remains in full force and operation. 35.2 Open Space and Agricultural Preservation Fee. The Landfill operator shall pay to the County of Contra Costa an Open Space and Agricultural Preservation Fee of $2.00 per ton on solid wastes received at the Landfill to mitigate the general impacts of the Landfill on open space, existing and proposed recreational facilities, and agriculture. The operator shall deposit the fee monies quarterly in a segregated account established by the County. The fee shall be considered to be a pass-through business cost for the purposes of rate setting. The fee shall be adjusted annually to reflect the current Consumer Price Index. The Board of Supervisors approved Amendment 1 to Land Use Permit 2020-89 on November 1, 1994 which stayed the operation of Conditions 35.1 and 35.2 as long as the new Condition 35.8 remains in full force and operation. 35.3 Property Value Compensation Program. The Landfill operator shall provide funding for the preparation of a property value compensation program study when requested by the County of Contra Costa. The study will address the means of determining the extent of property value losses or reductions attributable to Landfill impacts, such as aesthetics, noise, traffic, or pollution, and the means of compensating property owners for said losses or reductions. When a compensation program is adopted by the Board of Supervisors, the Landfill developer shall fund it in the manner specified by the Board. If the Board of Supervisors determines that progress on the implementation of a compensation program is not proceeding in a timely manner, the Board may require the use of a facilitator and/or an arbitrator. The fee shall be considered to be a pass-through business cost for the purposes of rate setting. 35.4 Resource Recovery Program Fee. The Landfill developer or operator shall pay to the County of Contra Costa a resource recovery program fee of Page 56 $200,000 annually, beginning July 1, 1990. The developer or operator shall deposit the monies in a segregated account established by the County. The extent of the fee shall be subject to reconsideration when a franchise or agreement is established for the Landfill. The resource recovery program fee from its inception shall be a pass-through business cost for the purpose of rate setting. The fee shall be adjusted annually to reflect the current Consumer Price Index. 35.5 Violation of Prescribed Haul Route. Upon a determination of the County that a user of the Landfill has violated Condition of Approval Section 29 by using a prohibited access route, and upon a written direction by the County, the Landfill operator shall impose on that user the sanction that is directed by the County. Such sanction may include a surcharge on the tipping fee, prohibition against accepting waste from that user for a designated period of time, revocation of County refuse-hauling license, or other sanction directed by the County. A system for reporting alleged violation and for monitoring enforcement data shall be established by the County and Landfill operator. 35.6 Direct Property Acquisition Study. The Landfill operator shall study the appropriateness of direct acquisition of properties immediately adjacent to the project, and shall fund any acquisition program ordered by the Board of Supervisors. The study shall be consistent with the Environmental Impact Report and shall be completed prior to the issuance of a franchise agreement. 35.7 Adjoining Sites. This permit authorizes the use of the Keller Canyon Landfill site only for its specified waste disposal uses as set forth in these Conditions of Approval, and for no other uses. In particular, during the effective and operative periods of this Permit, the Keller Canyon site covered by this Permit shall not be used to provide access to, or to accommodate in any way the use of, any adjoining property for landfill purposes, unless the County has approved the use of such adjoining property for landfill purposes. 35.8 Mitigation Fee. The Landfill operator shall pay to the County of Contra Costa a fee, the amount of which may be set by the Board of Supervisors by a Board Order from time to time, which amount shall not be less than $3.00 per ton and shall not be more than $4.00 per ton, on solid waste received at the Landfill. The fee shall be used as directed by the Board in its sole discretion: 1) to mitigate general impacts of the Landfill-generated traffic on the County's road system, 2) to mitigate the general impacts of the Landfill on open space, existing and proposed recreational facilities, and agriculture, or 3) to mitigate any general impacts of the Landfill upon the surrounding community. Page 57 Conditions 35.1 and 35.2 of Land Use Permit 2020-89 are hereby stayed in their operation as long as Condition 35.8 remains in full force and operation. Should Condition 35.8 (or any portion of it) for any reason be set aside or stayed in its operation, then Conditions 35.1 and 35.2 shall be in full force and operation. Condition 35.8 was added when Amendment 1 to Land Use Permit 2020-89 was approved. The Board of Supervisors approved Amendment 1 on November 1, 1994 which stayed the operation of Conditions 35.1 and 35.2 as long as the new Condition 35.8 remains in full force and operation. 36. LANDFILL GAS POWER PLANT 36.1 Power Plant Design. The design of the Landfill Gas Power Plant project as approved is generally shown on the plans submitted to the Community Development Department on October 16, 2001. 36.2 Ultimate Responsibility. These conditions of approval identify the Landfill Gas Power Plant operator as the party primarily responsible for implementing conditions involving the design, construction, improvements, maintenance and management of the power plant. However, ultimate responsibility for compliance with these conditions lies with the owner of the landfill. 36.3 Keller Canyon Landfill Land Use Permit. The construction and operation of the Landfill Gas Power Plant is also subject to all other conditions in Land Use Permit 2020-89 for the Keller Canyon Landfill, as appropriate. 36.4 Violation/Revocation. The Landfill Gas Power Plant owner and operator shall at all times comply with the provisions and requirements of these Conditions of Approval. A repeated violation of any of these Conditions as a result of the construction or operation of the Power Plant is cause for revocation of the Land Use Permit for the power plant. 36.5 System Safety. Risk of fire (from gas, oil, or electrical sources) shall be controlled through the use of flame sensors, ultraviolet (UV) radiation and methane detectors, and fire extinguishers. These components shall be installed at a minimum, in the power modules, exhaust and cooling packages, and other locations as required by Code. 36.6 Equipment and System Monitoring. Instrumentation shall be provided for all power plant equipment and systems which provide for a fully automated monitoring and warning system. This will include an automated switch to combustion flare if necessary. Additionally, routine monitoring of the gas extraction system and power plant facility shall be performed during normal business hours by at least one on-site operator. Page 58 36.7 Engines. Power plant facilities shall use lean burn internal combustion engines to meet BAAQMD regulations for oxides of nitrogen (NOx), carbon monoxide (CO) and volatile organic compounds (VOC). 36.8 Hazardous Materials. Landfill Gas Power Plant operator shall prepare and submit a Hazardous Materials Business Plan for the Power Plant in compliance with requirements of the Hazardous Materials Division of Contra Costa County’s Health Services Department. 36.9 Emergency Response. Landfill Gas Power Plant operator shall submit a facility specific Emergency Response Plan and then implement and update as needed, said Plan. 36.10 Notification of Plant Upset or Accidental Release. Landfill Gas Power Plant operator shall notify the Community Development Department immediately of any plant upset or accidental leakage or release of landfill gas. A written report of the cause of any plant upset and the corrective measures taken by the facility operator, shall be provided to the Community Development Department within 72 hours after resolving an emergency. 36.11 Stormwater Pollution Prevention Plan (SWPPP). Landfill Gas Power Plant operator shall implement the Keller Canyon SWPPP (prepared in 1996 and as may be amended from time to time), for water resources protection measures in case of spill of coolant, oil, or other lubricant. 36.12 Facility Design. Power Plant facilities shall be painted Bronze Olive or other suitable color as approved by the Community Development Department. Power Plant operator shall install a perimeter security fence to enclose the power plant. 36.13 Power Plant Landscape Plan. A Landscape Plan for the Power Plant site shall be submitted subject to the approval of the Community Development Department. The location and types of landscaping proposed along the security fence shall be specified. 36.14 Construction. Upon completion of construction, all construction materials, including packaging materials, worker facilities, and debris will be removed from the site. Additionally during construction all excess materials shall be removed periodically, as needed. 36.15 Material Recycling. Whenever feasible, all oils, lubricants, and coolant shall be recycled rather than disposed. Prior to issuance of a building permit, the applicant shall submit a Debris Recovery Plan. Upon completion of construction, the applicant shall submit a Debris Recovery Report. Page 59 36.16 Implementation & Compliance Monitoring. The operator shall provide payment for costs associated with the Community Development Department’s monitoring of implementation and compliance with these Conditions of Approval. 36.17 Surcharge. A surcharge, if established by the County Board of Supervisors, shall be paid to the County, by the operator, related to the sale of landfill gas or the sale of electricity produced by burning said gas. History of Revisions 7/24/1990 – Original Approval 11/1/1994 – Amendment 1 (added COA 35.8) 6/25/2003 – Amendment 2 (added Section 36 “Landfill Gas Power Plant” – LP012115) 3/23/2009 – Expanded the Table of Contents and added titles for COA 11.10 – 11.14 G:\Conservation\Matthew\Keller\KCL-LUPCOA_Amd2.DOC Page C-1 Further Information in Response to February 11, 2014 Letter from Miller, Starr and Regalia The following supplemental information provides background related to the conclusions identified in the “February 11th Letter from Miller, Starr and Regalia” section of the report to the Board. ANTI-TRUST & UNFAIR COMPETITION LAWS Alleged violations of state and federal unfair competition and anti-trust laws fall outside the County’s jurisdictional authority. It is not appropriate for the County to weigh in on allegations that anti-trust and unfair competition laws have been violated by Republic Services (Keller Canyon Landfill). In general, anti-trust and unfair competition laws are enforced by the District Attorney’s Office or the California Attorney General’s Office for state crimes, and by the United States Department of Justice if the violation is a federal crime. Absent evidence of a violation that has been prosecuted by one of the applicable authorities, the County is not able to speculate whether a violation occurred nor would it be appropriate to do so. If applicable authorities deem a violation has occurred, the County could decide to issue a notice of violation pursuant to LUP Condition 3.1 but would be under no obligation to do so. Prior to determining whether or not to issue a notice of violation, the specific circumstances would be considered, including what if any options exist to remedy said violation. The County may decide it is not appropriate to issue a notice of violation elect not to do so for the reasons explained in the response under Condition 3.1 in Attachment D. RATE DIFFERENTIAL ALLEGED TO VIOLATE CONDITION 5.1 Wilson Wendt’s February 11th letter suggests that Republic Services’ proposed Keller Canyon Landfill per ton rate for disposal applicable to CCCSWA franchise competitors violates Condition 5.1 of the Land Use Permit. This condition requires that Keller accept waste generated in the County provided that “appropriate disposal fees are paid”. Staff reviewed relevant background documentation to determine whether there is evidence that adequately demonstrates a violation has occurred. As noted in the report presented to the Board of Supervisors on February 25th, further staff review, consulting assistance, and a fair amount of time would be needed if the Board elected to pursue an official inquiry into the appropriateness of the fees. The Board did not direct staff to retain a consultant to pursue this matter in February and indicated this would be revisited if needed when returning to provide the Board with a status report in late April. Although the Keller Canyon Landfill LUP does not specify what constitutes “appropriate fees”, Condition 11.9 authorizes the Director of DCD to interpret the Conditions in the event any clarification is needed. DCD staff believes the County does not have adequate cause to find that the proposed disposal rate of $69.43 per ton is not “appropriate”. Although on the high end, this per ton amount does not exceed the range of rates charged to existing customers disposing of similar wastes according to ATTACHMENT C Page C-2 Keller Canyon Landfill’s Schedule of Rates. Based on the information and facts currently available, County staff does not believe there is adequate cause to pursue any further inquiry into the appropriateness of Keller Canyon Landfill’s disposal rate identified in Republic’s bid documentation submitted to the CCCSWA. Staff has completed our review of the applicable evidence and did not identify any need to retain a consultant to research this matter any further. County staff would not recommend that the County incur the expense to retain a consultant to investigate rates at this time. Dedicating resources to such an inquiry does not seem prudent considering that the County does not have the authority to regulate rates were the inquiry to conclude that a rate was not appropriate. The evidence reviewed substantiates the conclusion that no violation has occurred as Republic Services’ proposed Keller Canyon Landfill disposal rate submitted to the CCCSWA does not constitute a refusal to accept in-County waste for an appropriate rate. DCD staff would expect to revisit this issue in the future if circumstances change or new information becomes available at which time we would evaluate the relevant facts to determine what, if any, actions or recommendations may be warranted and allowable. KELLER CANYON LANDFILL’S LAND USE PERMIT CONDITIONS OF APPROVAL Although the February 25th report addressed all of the major issues or questions raised in this February 11th letter, there was not adequate time to present detailed responses about each LUP Condition cited in Mr. Wendt’s letter. Due to the shear volume of information involved, Attachment D was created solely to present detailed information responding to issues raised about each of the LUP Conditions cited in the letter dated February 11, 2014. REPORTING AND OTHER CCCSWA FRANCHISE REQUIREMENTS The February 11th letter includes a number of requests or allegations specific to the CCCSWA’s Franchise Agreement. It appears that the letter’s author mistakenly believed that the Franchise Agreement mentioned in Keller’s Land Use Permit referred to or included the agreement administered by the CCCSWA. The Franchise Agreement referred to in the Keller Land Use Permit is the Landfill Franchise and therefore does not empower the County to enforce requirements in Franchises administered by other agencies. The County and CCCSWA have differing authorities and responsibilities. There is nothing in Keller’s Land Use Permit providing the County with any authority over matters governed by the CCCSWA’s franchise. Therefore, it is not appropriate for the County to investigate compliance with the CCCSWA’s Franchise Agreement. S:\Deidra\Keller-Telma\Board Order 4-29-2014\ATTACHMENT C for 4-29-2014.docx Page D-1 Responses about Land Use Permit Conditions of Approval identified in the February 11, 2014 Letter from Miller, Starr and Regalia Compliance with Land Use Permit (LUP) Conditions – February 11th Letter Mr. Wendt’s letter includes issues or questions relative to multiple LUP Conditions. Each specified Condition is listed below followed by a summary of the issue(s) raised in the letter and information staff is providing in response to each. Many of the issues involve potential violations which have already be corrected, however others are specific to rates for disposing at Keller Canyon Landfill which were identified in documents related to the competitive CCCSWA franchisee selection process. Condition 3.1: Compliance Objective “The Landfill developer and operator shall at all times comply with the requirements of laws and permits applicable to the facility. “ ISSUE: Letter identifies various operational and business practices which are alleged to constitute multiple different violations, including potential violations of unfair competition and anti-trust laws. The February 11th letter seems to suggest that Condition 3.1 provides for determining a Land Use Permit violation has occurred any time Keller is not operating in compliance with all other permits and laws. RESPONSE: The County DCD does not take the lead in enforcing compliance with requirements in regulations or permits governed by other agencies. When an alleged violation involves a requirement in the LUP conditions that does not overlap with any other regulations or permits, DCD acts as the enforcement lead. When a potential violation pertains to requirements in the LUP and other permits or regulations, the County must assess the relative value of enforcing as an LUP violation on a case by case basis. A determination by the applicable authorities that the operator is not in compliance with applicable laws or permits could substantiate any decision the County may make with respect to the issuance of a notice of violation pursuant to Condition 3.1. When a potential violation involves an ongoing or periodic activity the operator can be held responsible for, the County can issue a notice of violation specifying corrective action to be taken. The first step in DCDs LUP enforcement process involve providing the operator with due notice and an opportunity to remedy the violation. In which case, said notice must specify what actions are required to correct said violation as well as the timeframe in which that must occur in order to avoid having the LUP be subject to revocation. The County’s options in terms of addressing LUP violations are somewhat limited because most violations can’t be reversed or undone. If a permittee neglects to implement the specified corrective action when required, the County’s could schedule hearings to consider modifying or revoking the Land Use Permit. ATTACHMENT D Page D-2 As noted in Attachment C, the County should defer any determination related to violations of state or federal anti-trust and/or unfair competition laws to the applicable authorities. Condition 3.3: State Minimum Standards “The operation and maintenance of this facility shall at all times comply with Minimum Standards for Solid Waste Handling and Disposal (California Administrative Code, Title 14, Division 7, Chapter 3).” ISSUE: Letter requests that County verify violations identified on US EPA’s and CalRecycle’s online databases and which if any constitute infractions under the California Code of Regulations (CCR), Title 14. RESPONSE: County Environmental Health is designated as the Local Enforcement Agency responsible for working with CalRecycle to enforce State regulatory requirements applicable to transport, handling, processing and disposal of solid waste pursuant to Title 14 and 27 of the California Code of Regulations (CCR). The LEA enforces certain state minimum standards for landfills and other solid waste facilities. The permit that most comprehensively addresses operational requirements at Keller Canyon Landfill is the Solid Waste Facility Permit. A number of the conditions in Keller’s Solid Waste Facility Permit are borne from these minimum standards. The Solid Waste Facility Permit is issued by CalRecycle and enforced by Environmental Health as the Local Enforcement Agency (LEA). Pursuant to Condition 11.11 DCD staff relies upon the LEA as the agency with primary jurisdiction to make determinations about the landfill operator’s status of compliance with the specified minimum standards contained in state regulations. Staff has not found any evidence that proves that Keller is not currently in compliance with the Minimum Standards for Solid Waste Handling and Disposal. Condition 3. 6. Subchapter 15 “The Landfill operator shall at all times comply with the provisions and requirements of Subchapter 15 of Chapter 3 of Title 23 of the California Administrative Code ("Subchapter 15") for a Class II waste disposal facility.” ISSUE: Letter requests that the County evaluate the Landfill’s compliance with specified State regulations pertaining to Class II waste disposal facilities. RESPONSE: The condition actually includes an outdated regulatory citation which is no longer accurate due to changes in state law. The County does not have authority over the specified Title 23 requirements. Title 23 regulations fall within the purview of the Regional Water Quality Control Board. This agency is also responsible for enforcing compliance with each solid waste facility’s Waste Discharge Requirements (WDRs). Pursuant to Condition 11.11 County staff relies upon the agency with primary jurisdiction to make determinations about regulatory compliance or violations of the State’s requirements specific to Class II waste disposal facilities. Page D-3 Condition 5.1: Area of Origin “The area of origin of all waste hauling vehicles admitted to the landfill, shall be Contra Costa County. The Landfill operator shall not refuse to receive eligible wastes which originate in Contra Costa County provided such wastes are delivered to the facility in accordance with these Conditions of Approval and the landfill's Solid Waste Facilities Permit, and provided that appropriate disposal fees are paid.” ISSUE: Letter alleges that the Land Use Permit vests the County with the authority to set “appropriate” rates. RESPONSE: The purpose of this Condition is to establish mandatory acceptance of in- county wastes not establish requirements specific to rates which are all in Section 12 of the Land Use Permit conditions. However, the County contracted away an ongoing right or obligation to approve Keller Canyon Landfill’s rate in 1994 as discussed in more detail in the February 25th report to the Board. This issue is discussed in more detail in the “Rate Differential Alleged to Violate Condition 5.1” section of Attachment C. Condition 7.1: Eligible Vehicles and Loads “The Landfill operator shall screen loads to limit to the extent practicable the intake of ineligible waste. Prior to receiving waste, the Landfill operator shall prepare in writing a program for identifying eligible vehicles and screening loads at the Landfill entrance, random sampling and inspection for ineligible wastes, and checking loads at the Landfill disposal area. The Load Inspection program shall include inspection for hazardous wastes and procedures for their handling and off site disposal consistent with the Contra Costa County Hazardous Waste Management Plan. The program shall be subject to the approval of the County Health Services Department and the County Community Development Department.” ISSUE: Letter requests that the County investigate to verify if only eligible waste types have been received and disposed of, and asks if there have been complaints about accepting ineligible wastes. RESPONSE: Information about historical incidents of ineligible waste acceptance at Keller involving the County LEA was included in the February 25th report to the Board of Supervisors. The LEA has no record of ineligible waste acceptance being reported since 2005. In that case, a load was identified that should not have been delivered to the facility; the operator self- reported the issue and took corrective action. The only incident involving the acceptance of ineligible waste acceptance which resulted in the issuance of a notice of violation by the Department of Conservation & Development occurred in 2001. Staff concluded that certain precautionary measures were needed to avoid similar occurrences involving the disposal of ineligible waste loads as a result of procedural errors by the generator and landfill. Following the issuance of the notice of violation, the landfill operator took appropriate corrective actions in a timely manner. Page D-4 Condition 11.1: Permit Review “The Board of Supervisors will hold annual public hearings to review the Conditions of Approval for this Land Use Permit for three years beginning one year after the commencement of operations of the Landfill. The Board may refer proposed changes to the Land Use Permit to the County Planning Commission for processing. Thereafter, the County Planning Commission shall hold public hearings on the Land Use Permit at three-year intervals. As a result of a review and public hearing, the County Planning Commission may recommend to the Board of Supervisors new or modified conditions to improve the public health, safety, and welfare. Nothing in this condition shall preclude the Landfill owner from applying for amendments to the Land Use Permit at any time or preclude the County from addressing emergency situations or new requirements imposed by State or Federal legislation or the courts.” ISSUE: Letter requests that the Board consider imposing additional conditions in the interest of “fair competition”, which presumably involves changing how rates are set. RESPONSE: As explained in Attachment C, the County would rely on the applicable authorities to make any determinations about whether or not anti-trust and unfair competition laws have been violated by Republic Services (Keller Canyon Landfill). Additionally, as noted in the February 25th report to the Board, the terms of the Keller Canyon Landfill Franchise Agreement limit what control, if any, the Board can exercise over rates charged at Keller Canyon Landfill. As discussed in the April report to the Board, the County has initiated the Permit Review Process which is expected to be completed in late August as directed by the Board on February 25th. Condition 11.6: Compliance and Mitigation Monitoring Program “The Landfill operator shall provide a fund to support County staff monitoring of compliance with Conditions of Approval and mitigation monitoring programs, as designed and implemented by the County Community Development and Health Services Departments.” ISSUE: Letter requests a copy of Keller Canyon Landfill’s Compliance and Mitigation Monitoring Program. RESPONSE: A copy of Keller Canyon Landfill’s Implementation & Mitigation Monitoring Program dated March 1, 1993 is included as Attachment G. Information regarding ongoing compliance monitoring is contained in the Background section of the April 29th report to the Board of Supervisors. Departmental staff costs associated with monitoring compliance is reimbursed by the landfill operator. Condition 11.11: Regulations Enforced by Other Agencies “Several of these Conditions of Approval relate, paraphrase or summarize laws and regulations which are imposed and enforced by other governmental agencies which have jurisdiction over particular aspects of this project. It is this Board's intent in adopting these Conditions Page D-5 of Approval to provide the applicant and the public with an overview of the scope of regulation applicable to this project and to provide this County with enforcement power if such laws and regulations enforced by other agencies are violated. Unless specifically stated in the Conditions of Approval, however, it is not this Board's intent to establish rules or regulations which are stricter than the laws or regulations which are applied to this project by the other agencies with jurisdiction over aspects of this project. If another agency primarily responsible for some aspect of this project finds that any action or inaction is in compliance with, or violates, any such law or regulation, that finding shall be conclusive. If these Conditions of Approval require some approval by any other agency and that agency declines to approve or disapprove the subject matter, such approval shall be deemed to have been given for purposes of these Conditions of Approval.” ISSUE: Letter requests that County consider taking action on past violations reflected in US EPA and CalRecycle databases. RESPONSE: Letter seems to suggest that Condition 11.11 provides for and/or intends to have multiple agencies taking duplicative enforcement actions resulting in multiple penalties for a single violation. Condition 11.11 clearly states that the Land Use Permit conditions are not intended to establish rules stricter than the laws/regulations. Furthermore, it states that the agency with primary jurisdiction has final word about determining that an action or inaction complies with or violates any such law. This request about permit violations is duplicative of the request discussed under Condition 3.1 above. See discussion in “Operational Issues” section of the February 25th report to the Board of Supervisors. Most of the ongoing activities the operator is responsible for in order to remain in compliance with their LUP involve operational requirements that are also contained in permits or regulations enforced by County Environmental Health. Environmental Health conducts unannounced inspections of the landfill each month and any violations are noted in writing in their official inspection reports. Where the LUP requirement overlaps operational requirements enforced by Environmental Health, their enforcement efforts have proven to be quite effective and DCD has rarely found it necessary to initiate separate enforcement actions. If the violation involves a recurring situation that may lead to future undesirable outcomes, it may be worthwhile for the County to issue a notice of violation clearly indicating what the permittee should do or not do to prevent or avoid similar violations from that point forward. Condition 12. 2: Rate Review “The Board of Supervisors shall review and approve rates annually in accordance with an approved rate application procedure. More frequent review of rates may occur if requested by the landfill operator and if the Board determines that changing circumstances warrant such review. The Board may also review rates more frequently if the Board determines that it is in the public interest to do so.” Page D-6 ISSUE: Letter requests that the Board expeditiously establish a range of reasonable rates for Keller Canyon Landfill. RESPONSE: The County contracted away an ongoing right or obligation to approve Keller Canyon Landfill’s rate in 1994 as discussed in more detail in the February 25th report to the Board. Condition 12. 3: Form and Content of Rate Review Application “The landfill operator shall submit its rate application in a form and content as specified by the County. Such application may require the landfill operator to submit the application on forms and/or using computer software provided by or specified by the County. The County shall have the right to inspect and audit all records of the landfill operators which support its rate review application.” ISSUE: Letter requests that the Board expeditiously establish a range of reasonable rates for Keller Canyon Landfill. RESPONSE: The County contracted away an ongoing right or obligation to approve Keller Canyon Landfill’s rate in 1994 as discussed in more detail in the February 25th report to the Board.

ALTERNATIVE DAILY COVER (ADC) TONNAGE REPORTING FOR CCCSWA AREA ADC tonnage reported to CalRecycle comes from the quarterly reports required by the State’s Disposal Reporting System (DRS) regulations. All permitted landfills are obligated to submit these reports to their respective host County which the host County must then submit to CalRecycle.. The reports submitted to CalRecycle with ADC tonnage used at local operating landfills are based on data the County receives from the operators of the two in-county landfills. Each quarter, the landfill operator submits quarterly data to the County reflecting the tons disposed and used as ADC at Keller Canyon Landfill, by jurisdictions of origin. The County distributes quarterly reporting data to contacts for each of the applicable jurisdictions of origin as well as CalRecycle as required by State regulations. Keller Canyon Landfill’s quarterly reports have been submitted in compliance with the applicable regulations. Neither of the specified reports submitted to CalRecycle listing ADC tonnage received by Keller provide a means for determining the total amount of ADC that originated from within the CCCSWA boundaries. This is because both reports reflect the “jurisdiction of origin” as defined in the applicable CalRecycle reporting requirements. CalRecycle considers the CCCSWA to be one jurisdiction for reporting purposes which is comprised of the incorporated areas within the five member cities. However, CalRecycle considers the entire unincorporated area (including the portions within the CCCSWA area) to be one reporting jurisdiction. Therefore, all unincorporated area ADC tonnage is combined for CalRecycle reporting purposes consistent with applicable State law and does not include any breakdown showing about for the unincorporated CCCSWA area. PROPER HANDLING & USE OF ADC – UNPROCESSED & FOOD WASTE Keller Canyon Landfill’s operations, including the use of ADC, are subject to routine scrutiny to ensure the facility remains in compliance with the applicable state standards. The primary means of scrutinizing the landfill’s status of compliance is the unannounced monthly inspections that are conducted by the County’s Environmental Health Division, operating as the Local Enforcement Agency (LEA). As the LEA, Environmental Health is responsible for working with the State agency known as CalRecycle to enforce State regulatory requirements applicable to the transport, handling, processing and disposal of solid waste as well as Keller’s solid waste facility permit. The allegations related to the improper handling or use of green waste as ADC are based on concerns related to processing (grain size requirements) and food waste (allowable contamination). ATTACHMENT E Page E-2 The purpose for including grain size requirements in the regulations governing the use of ADC is to ensure adequate compaction potential of any materials being used for cover. Adequate compaction of cover material helps ensure it serves as an effective barrier to minimize infiltration of rainwater. Additionally, compacted cover material traps landfilled waste and associated leachate and emissions within the landfill and its associated control systems designed to manage any waste related fluid and gaseous byproducts. Up to 5% of the ADC material used at Keller can be greater than the maximum grain size requirement without triggering a violation. When combined, the items that the CalRecycle staff person noted during the joint inspection in 2007 still fell well below the 5% threshold. CalRecycle’s 2007 violation notice stated that the Alternative Daily Cover (ADC) was not properly processed off-site before being used on-site. The green waste used for ADC at Keller has not required processing as it generally comes in to the facility in usable condition directly from curbside collection. That material is spread and compacted using the bulldozers and compactors. The LEA inspector has not found any such violations nor has the other CalRecycle inspectors found any problems with the ADC since that date. With respect to food waste, ADC material observed during inspections has not contained any significant amount of food waste. Materials collected from CCCSWA customers in areas that allow food waste to be placed in green waste carts are not being comingled with materials used as ADC. in with their green wastenone of the green waste mixed with food waste collected from customers the green waste mithe LEA has informed Keller Canyon that green waste which is mixed with any appreciable amount of food waste cannot be used as ADC; inspections by the LEA have not found ADC mixed with food waste. State regulations allow up to 1% of contaminants (including food waste) to be included in ADC. For the reasons identified herein and in the “Operational Issues” section of the February 25th report, staff does not agree with the author’s conclusion that green waste has been improperly classified as ADC. FEES PAYABLE TO THE COUNTY FOR GREEN WASTE USED AS ADC It is common practice for agencies to waive or reduce per ton fees imposed on incoming material not disposed of as waste as a financial incentive to increase diversion. Contra Costa County established a disposal based fee structure applicable to waste accepted at Keller Canyon Landfill. The fees imposed by the County and CalRecycle only apply to disposal and are not assessed on the tons of material that is used as ADC or other beneficial reuse on-site. Therefore, whether or not County fees apply to any particular load being accepted at Keller Canyon Landfill depends upon whether it contains waste to be disposed of. The letter improperly concludes that large amounts of green waste were improperly used as ADC and therefore should have been subject to all of the County disposal-based fees. The letter contains unsubstantiated conclusions which may be due in part to misunderstandings related to Republic’s operations at the transfer station near Martinez and Keller Canyon Landfill. In order to substantiate the claim that additional fees are due for green waste reported as ADC, some conclusive information to that effect would need to be obtained from the applicable regulatory agency(ies). The two Page E-3 agencies with the authority to determine whether or not materials meet the applicable ADC requirements is County Environmental Health and CalRecycle. In fact only one notice of violation relative to ADC has ever been issued (this occurred in 2007). Staff has seen no evidence of on-going problems associated with ADC compliance. Both agencies have conducted multiple inspections since 2007 and no further ADC related violations have been issued by either agency. There is no information presented in the letter dated February 18th that adequately substantiates the allegation that the County has not been paid the total amount of fees (surcharge) due for green waste classified as ADC. County staff will continue monitoring relevant facts about the landfill’s operations and the manner in which fees are calculated and paid to help ensure that County fees are consistently assessed on all waste that is actually being disposed. S:\Deidra\Keller-Telma\Board Order 4-29-2014\ATTACHMENT E for 4-29-2014.docx Page F-1 Further Information in Response to February 25, 2014 Letter from Miller, Starr and Regalia The following supplemental information provides background related to the conclusions identified in the “February 25th Letter from Miller, Starr and Regalia” section of the report to the Board. FEES ALLEGED TO BE DUE FOR IMPROPER USE OF ADC & BENEFICIAL REUSE The applicable body of evidence reviewed by staff does not substantiate the allegations that green waste is being accepted or handled improperly. Therefore, no additional County fees are due for green waste material that has actually been used as ADC. Details substantiating this conclusion are contained in Attachment E. DIRECT HAUL OF GREEN WASTE AND C&D VIOLATES THE SOLID WASTE FACILITY PERMIT Direct haul of green waste used for ADC does not violate the Solid Waste Facility Permit. The requirement specified in 17(i) of the Solid Waste Facility Permit only applies to acceptance of Municipal Solid Waste (MSW). This requirement is intended to foster diversion of MSW prior to acceptance at Keller. However, Keller’s use of ADC and beneficial reuse has provided a means to increase diversion on-site for green waste and certain construction and demolition(C & D) wastes. The manner in which non- MSW is delivered and accepted at the landfill (direct haul or otherwise) has no bearing on the status of compliance with this requirement.   As noted previously, Environmental Health, acting as the LEA, responds to any complaints received and inspects the landfill on a monthly basis to enforce Solid Waste Facility Permit compliance. The LEA routinely reviews relevant facility records, makes their own personal observations of various aspects of the landfill’s operations as well as interviews landfill employees as needed during monthly inspections. To date, there has been no evidence found that would warrant issuance of a violation related to direct haul of municipal solid waste pursuant to Section 17(i) of the Solid Waste Facility Permit. REPORTS REQUESTED IN FEBRAURY 11TH LETTER With the exception of the Implementation & Mitigation Monitoring Program (Attachment G) noted in LUP Condition 11.6, the letter requests reports required by the CCCSWA Franchise Agreement. For the reasons stated in the “Reporting and Other CCCSWA Franchise Requirements” section in Attachment C, it is not appropriate for the County to become directly involved in matters related to the implementation or enforcement of requirements in the CCCSWA’s Franchise Agreement. NOTICE OF VIOLATIONS NOTED IN EARLIER LETTER(S) This letter suggests that the February 25th report does not discuss each of the violations noted in the prior letters. Although not discussed in detail, the prior report did mention a couple of violations issued in the past by the County LEA or CalRecycle. As noted previously, the County LEA conducts monthly, unannounced inspections of the site. In addition to these monthly inspections, every 18 months the LEA conducts a joint inspection of Keller Canyon Landfill with CalRecycle inspectors. The violations issued by ATTACHMENT F Page F-2 the County LEA and CalRecycle generally result from observations or information gathered during their inspections. Over the operating life of the landfill, the LEA indicated that their inspectors rarely find cause for issuing violations to Keller Canyon Landfill. As explained in the February 25th report, appropriate corrective actions have been taken in a timely manner when violations have been identified in the past. There has only been one violation issued related to the handling of green waste accepted for use as ADC. The February 25th report contains details about this violation issued by CalRecycle in 2007, which was based on a misunderstanding about what in fact CalRecycle staff observed on-site (material in a stockpile mistakenly characterized as ADC by CalRecycle staff). Putting aside any question as to the validity of this past violation, it is important to note that CalRecycle inspectors have not issued subsequent similar violations since. The fact that no additional violations have been issued by CalRecycle indicates that state staff has not observed any improper handling of ADC although they have conducted at least 4- 5 subsequent joint inspections since that time. Staff reviewed the information contained in the ECHO database relevant to the Keller Canyon Landfill. The only relevant regulatory information listed for the landfill site pertains to the Clean Air Act. According to that database, there were two “Enforcement Actions” in the past 5 years, both of which occurred in 2010. The first is labeled as a State Notice of Violation and the second is listed as a State Administrative Order. Any permitting requirements associated with the Clean Air Act applicable to Keller Canyon Landfill are contained in the Title V Permit issued by the Bay Area Air Quality Management District (BAAQMD). The Title V Permit governs the monitoring and control of gas emissions and migration and fugitive dust. The Title V Permit was issued by the BAAQMD in January 2008, which consolidated all BAAQMD operating permits and compliance plans required for the landfill site. Staff requested and received some information from Republic Services related to the violations that were noted in the EPA’s ECHO database report enclosed with Wilson Wendt’s letter to the CCCSWA dated February 14, 2014. The information provided by Republic Services is contained in Attachment H. Republic Services has indicated that a majority of the information in that database is either outdated or inaccurate. To date the company has been unsuccessful in reaching anyone responsible for entering or updating that information. When responding to alleged LUP violations, it is worthwhile to first consider what options or limitations are dictated by the County’s legal authority. The only penalty available if a land use permit violation is not corrected is to officially revoke the permit after providing due notice. To the extent that violations occur in the future, the manner in which they would be handled would vary depending upon whether or not the violation applies to requirements enforced by multiple different agencies. If the violation solely pertains to requirements unique to the LUP, no agency other than the County has the enforcement authority or responsibility. Where the circumstances involve potential violation of requirements in the LUP as well as other permits or regulations handled by different agencies, the County is best served assessing the relative value of enforcing as an LUP violation on a case by cases basis depending on the relevant context for each situation. In most cases, other agencies with primary jurisdiction over the violation have the ability to exercise more effective and appropriate enforcement options. Further Page F-3 information is provided in Attachment D related to the approach used when multi- jurisdiction enforcement is involved (see section related to Condition 11.11). S:\Deidra\Keller-Telma\Board Order 4-29-2014\ATTACHMENT F for 4-29-2014.docx  1 KELLER CANYON LANDFILL Evaluation of EPA ECHO Detailed Facility Report Background The Board Order dated February 25, 2014 includes a report from the County Administrator regarding issues raised at the February 11, 2014 meeting related to the proposed franchise agreement to be issued by the Central Contra Costa Solid Waste Authority (CCSWA). Part C of the County Administrator's report (Violation of Operational Requirements at Keller Canyon Landfill) correctly summarized that the LEA found that the Keller Canyon Landfill has operated with a high degree of compliance, and that when violations or issues have been noted, the landfill operator has been responsive in taking corrective actions. The LEA report concluded that the Keller Canyon Landfill does not have chronic violations or operational issues. Allegations of Non-Compliance Miller Starr Regalia submitted a letter dated February 14, 2014 to the Chairperson of CCSWA containing a list of questions and allegations of non-compliance by Republic Services ("Republic") with the LUP and applicable law. Specifically, page 2, Item 3 of the letter references an attached report from Loewke Planning Associates. EPA's ECHO (Enforcement and Compliance History Online) website and Detailed Facility Report for Keller Canyon Landfill (KCL) is cited as containing documentation of notices of violation with various agencies. The ECHO report indicates 12 quarters of Significant Violation. After reviewing the Miller Starr letter and allegations concerning the EPA ECHO website, Republic counsel attempted to reach ECHO personnel responsible for website content, without success. The ECHO website does not appear to be an actively managed website, and did not have a webmaster contact readily accessible when Republic counsel inquired regarding the validity of the database entries. Republic downloaded the report as of April 3, 2014 and checked the data in the ECHO database for accuracy. Republic provides the following general response: 1. Republic counsel noted that the database is quite dated, and appears to be only infrequently updated. 2. The ECHO database contains inaccurate and incomplete data related to recorded violations and corrective actions taken by Republic Services. The designation of 12 Quarters of Significant Violation is erroneous and unsupported by records. In addition, the designation of KCL as a High Priority Violator (HPV) is incorrect, inappropriate, and also not supported by the record. We anticipate that continued effort will be made to correct the database inaccuracies. 2 3. Conclusions by Loewke Planning Associates based on data currently contained in the ECHO Detailed Facility Report for KCL are therefore inaccurate and, if left uncorrected, are misleading to the County Board and CCSWA Board. Review of the ECHO Detailed Facility Report for Keller Canyon Landfill Republic Services disputes a number of data fields in the ECHO Detailed Facility Report for KCL including: 1. Page 2, under Enforcement and Compliance Summary: shows 12 quarters in Significant Violation. Republic Services disputes this data and can demonstrate that there were not 12 quarters of Significant Violation during the period specified. Republic believes this section requires updating to reflect corrective actions taken related to NOV No. A49170 in December 2008. Detailed information on this NOV is provided in the section that follows in Republic's summary of recorded violations. 2. Page 2, under Enforcement and Compliance, Compliance Monitoring History (5 years): there are no Findings presented. In addition, Republic has no record of a State PCE/On-Site inspection occurring on 12/18/2009 as shown. 3. Page 3, under Compliance Summary Data: as noted in Item 1 above, Republic disputes the "Yes" under the Current SNC/HPV pertaining to a High Priority Violator. Republic believes this Yes designation was triggered by the erroneous data indicating 12 quarters of significant violations. 4. Page 3, under Three Year Compliance Status by Quarter: as noted previously, Republic strongly disagrees and disputes the designation of KCL as a HPV for the indicated 3-year period inclusive of April 1, 2011 through March 41, 2014. 5. Page 3, under Formal Enforcement Actions (5 Years): the Penalty of $2,250 levied on 12/13/2010 is incorrect and is likely a duplicate of the Penalty of $2,250 shown at the top of page 2 under "Enforcement and Compliance Summary." While KCL has received an occasional notice of violation during the course of operating a facility within a complex and evolving regulatory structure, the record demonstrates the operator always responds to any compliance concerns in a timely and decisive manner.
