This includes the issuance of a Notice of Exemption by the CIWMBIfor this project under the California Environmental Quality Act. 1 In 1994,.BKK submitted to the California Integrated Waste Management Board (CIWMB) a Closure and Postclosure Plan.for the Class III Disposal Area. In early 1995, City staff, the Waste Management and Environmental Quality Commission and the public completed a review of these Plans. We formulated comments and transmitted them to the CIWMB. On December 20, 1995, the CIWMB issued of a Notice of Exemption under the California Environmental Quality Act and approved the Preliminary and Partial Final Closure Plan and Postclosure Maintenance Plan for the Class III Disposal Area at the BKK Landfill Attached are the CIWMB documents that are related to this project. These documents are: A Notice of Exem that relies onIa Class l Exemptio Exemption relate protection ofpu tion under the California Environmental Quality Act Class 1 and Class 8 Categorical Exemption.

The Class 8 to a project that provides for the enhanced lic health and safety. • An approval of'the Preliminary and Partial Final Closure Plan and Postclosure Maintenance Plan for the Class III Disposal Area at the BKK Landfi,ll.. IThis includes the revisions that CIWMB requested BKK • make to the Plans. To date, the City has not received a copy of the revised plans referred to by the CIWMB. • A copy of the CIWMB response to comments on the Preliminary and Partial Final Closure Plan and Postclosure Maintenance Plan for the Class III Disposal Area at the BKK Landfill. This contains the comments from the City, Commission and the public and the CIWMB responses. Under the regulations of the California Environmental Quality Act, any responsible agency or person may file a challenge to the Notice of Exemption within 35 days of its issuance. This challenge must be filed in Superior Court. There will be no public hearing or further public review of the matter unless the Court determines such is needed or required. This is probably the first time!the public has had an opportunity to see the responses from the CIWMB. Apparently there is no requirement that the CIWMB provide a copy of the responses to those people or agencies who made comments on the plans. There is.no specific action the staff suggests be taken on this matter. Any possible legal action is something for City Council to consider. The public may want to communicate their thoughts on this matter to the CIWMB. Recommendation Is recommended that this report;be received and filed. e - Michael L.

Gar-,-,--,- Avenue South I;Vest Covina, California 91793 RE: Preliminary- and Partial Final Closure and Postclosure Maintenance Plans, BILK Landfill, Class III Disposal Area, Facility No. 19-AF-0001 Dear Steve: The following provides} a response to your October 5 and 26, 1995 letters concerning Preliminary and Partial Final Closure and Postclosure Maintenance Plans (Preliminary and Partial Final Plans or -Plans) for the BKK Landfill. CIWVIB staff appreciate your comments and assistance on BKKf closure/postclosure issues. -Your letter raises two main issues regarding the Plans, compliance with the California Environmental Quality Act (CEQA), and ------ --- ---approval of the Plans by the LEA. Your letter questions GIWMB staff s determination that approval of the Plans is exempt from CEQA pursuant to Section 15301 of Title. 14, California Code of Regulations (14 CCR) (Class 1 Exemption). Class 1 exemptions apply to operation and maintenance of existing private facilities involving negligible or. no expansion of use beyond that previously existing. CIWMB staff contend that the Class 1 categorical exemption would apply to approval of the Partial Final Plans because they. address operation and maintenance activities that involve no - expansion of use beyond that previously existing. The BKK Partial Final Plans specifically address placement of final cover as the site progressively reaches final grades. BKK has been implementing this activity since 1992 as prescribed'in the Solid Waste Facilities Permit, Unclassified Use Permit No. 71 Revision 5 Amendment (Items 4.E., I LF., and 25), and Waste Discharge Requirements (WDRs) Order No. 87-39 (Finding 22). Specifically, your lettei states that in the LEA's review of both statutory and categorical exemptions from CEQA, a categorical exemption from CEQA is not found that is applicable to approval of closure land postclosure plans. Furthermore, your letter states that the regulatory mandate under 14 CCR 18270 of 14 CCR, Division 7, Chapter 5, Article 3.4 is in direct conflict with the notion of -a CEQA exemption. Prinwd on Rerydrd Paper -- Final Draft Working Cope November ?. 1995 (Revision 3) T'.. r:..al c-_-- -....t of Reasons for 14 CCR r..=.:! os (Jure 199 i c'o` idts a cco-c':'_=i`%e basis that such an e .Y'�t:Cri VVo iii not re in conflict %v;r,l 14 CCR Section. 132.The Final Statement of 'R.aScns states: "because land.iill closure is a project requiring diSc-;!, ovary government approval subsection 18370(aj requires th. board and (subsection: (c 4 requires the LEA] to ensure that an environmental document has been prepared for the project that is adequate and appropriate for the project and reflects full compliance with CEQA". Clearly, the intent is that compliance with CEQA be ensured because landfill closure is a project requiring discretionary approval. The type of documentation to ensure compliance with CEQA is not specified, nor could it be without conducting a preliminary review or initial study for each specific project. The Final Statement of Reasons also confirms CIw'MB's determination that the preferred method of closure for protection of public health and safety and the environment is partial closure as the site is filled (paragraph 3 ,of page V 3.4 - 9). This method is being implemented by BKK. The Partial Final Plans ensure that the final cover is placed in a manner that meets the standards of 14 CCR and provides a high level of short and long term containment for protection of public health and safety and the environment. If final cover is not placed as the site reaches final grades in accordance with the Solid Waste Facilities Permit and WDRs, CIW-TMB staff are concerned that maintenance of existing site containment may be jeopardized. Concerns have also been expressed regarding the Partial Final and Preliminary Plans authorizing or sanctioning site operations, grading, and closure dates which are under dispute. These concerns are unfounded. Preliminary Plans solely address conformity with 14 CCR closure/postclosure regulations and cannot be implemented. The Partial Final Plans do not sanction site configurations which are not authorized and only address implementation of individual closure activities that invalye no expansion of use beyond that previously existing. The Plans must be amended or revis, d as necessary to reflect resolution of ongoing disputes and any permit changes, until final closure/postclosure plans for complete site closure are submitted. This would be required . pursuant to 14 CCR 18272 and 18276. To confirm CIWMB staff s determination on CEQA, a Notice of Exemption (NOE) pursuant to 14 CCR 15374 will be filed upon approval of the Plans. Although approval of the Plans is exempt from CEQA, extensive environmental review and consideration of comments from the public and public agencies has been incorporated in the closure/postclosure plan review, process (see following section and Attachment). In addition, any permit action would be subject to a separate CEQA review as appropriate. %1r.

Minimum and safety and the environment that apply to the ipter 3) also apply to the partial final closure project. Approximately 0.85 million cubic yards of compacted soil from the existing onsite low permeability material borrow sources will be used for the final cover. The final cover will ultimately be constructed over the�entire Class III waste fill area (approximately 1.79 acres). Final cover. placement for 24 of the total 179 acres has been already completed since Page 1 CE � Preliminary Review and Initial StuuChecklist BKK Landfill Partial Final Closure and Postclosure Maintenance Plans 1992. Thickness of the proposed Final cover is a minimum of five feet, as compared with a required daily cover minimum thickness of one foot. The Partial Final Postclosure %faintenance Plan is required to ensure that the final cover and environmental monitoring and control systems are maintained to protect public health and safety and the environment throughout the postclosure maintenance period. The postclosure maintenance period will continue as long as the site poses a threat to public health and safety and the environment and spans a minimum of 30-years from the date of final closure (14 CCR, Division 7, Chapter 3, Article 7.8). Phased closure as specified in the Partial Final Closure Plans will be constructed as annual increments. The final closure date is currently the subject of a legal dispute between. the City of West Covina and BKK. If the final closure date or grading plans change, the Preliminary and Partial Final Closure Plans will require revision or amendment pursuant r•. CCR 18272 and 18276. The Partial Final Closure and Postclosure Maintenance Plans do not address complete site closure. Separate Final Closure and Postclosure Maintenance Plans for complete site closure are required pursuant to 14 CCR 18255(a). The placement of final cover as portions of the site reach final grade is an ongoing activity as prescribed in the Unclassified Use Permit No. 71 Revision 5 Amendment (Items 4.E., 11.F., and_25) issued by the City of West Covina. Approximately 24 acres of final cover has been constructed since 1992, consistent with the Preliminary and Partial Final Closure and Postclosure Maintenance Plans. The proposed project has been approved by the Los Angeles County Regional Water Quality Control Board (LARWQCB) on March 29, 1995, and is consistent with current Solid Waste Facilities Permit 19-AF-0001 issued by the City of West Covina Solid Waste Local Enforcement Agency (LEA) in 1979. Landfill gas monitoring and control is also required pursuant to permits issued and enforced by.. the South Coast Air Quality Management District. The facility is also subject to a Stipulated Permanel' '` Injunction (SPI), a court action primarily addressing landfill gas monitoring and control. The SPI was initiated in 1984 and is currently in effect. The site also contains a f� mer hazardous waste landfill which is subject to various regulatory orders issued by the U.S. Environmental Protection Agency (US EPA) and the Department of Toxic Substances Control (DTSC). H. Project Environmental Setting The project site is.an active Class III municipal solid waste landfill located within the city limits of West Covina, Los Angeles County. The site comprises 583 total acres of which - approximately 350 acres have been used for waste disposal. An additional 24 acres (North Area) is planned for waste disposal. Landfill operations started in 1963. Surrounding land use is predominantly residential and commercial. The closest homes are within 200 feet from the limits of waste disposal of the former Class I/III landfill.

Page 3 CEQAfreliminary Review and Initial Stu}Checklist BKK Landfill Partial Final Closure and Postclosure Maintenance Plans IV. Significant Effects, Mitigation Measures, and Alternatives to the Project Based on preliminary analysis. CI%�-%M has determined that the proposed project is exempt from the California Environmental Quality Act (CEQA) in accordance with 14 CCR Section 15301 (Class 1 Exemption). The basis for this determination is that the project consists of activities which involve negligible or no expansion of use beyond that previously existing. In addition, because approval of the proposed project by CIWMB consists of an action taken by a regulatory agency under it's authority to assure the maintenance, restoration, enhancement, or protection of the environment where the regulatory process involves procedures for protection of the environment, the proposed project is also exempt from CEQA in accordance with 14 CCR Section 15308 (Class 8 Exemption). Preliminary Closure and Postclosure Maintenance Plans solely address conformity with 14 CCR c losure/po stc 16 sure requirements and therefore do not constitute a project under CEQA. The purpose of this review and attached Initial Study Checklist is to determine if an exemption is consistent with the provisions of 14 CCR 15300.2 in order to confirm if the proposed project is exempt from CEQA. Based on the attached Initial Study Checklist, CIW1VIB has determined.that the project will not have a significant effect on the environment as that term is defined in the Public Resources Code Section 21068, and is exempt from CEQA in accordance with the Class 1 and Class 8 categorical exemptions. The proposed project will be conducted under the oversight of CIWMB and the LEA utilizing all applicable minimum standards as required under 14 CCR, Division_7, Chapter 3. The only alternative to the proposed project identified is to delay all closure activities until complete site closure. This alternative would significantly delay attainment of higher standards for environmental control and would be in conflict with protection of public health and safety and the environment. Page 4 Attachment 1 Initial Study Checklist for BKK Sanitary Landfill Class III Disposal Area Partial Final Closure and Postclosure Maintenance Plans The purpose of this checklist is to identify ,any reasonable possibility of "significant effect on the environment" as that term is used in Section 21068 of the Public Resources Code and to determine if the exceptions pursuant to 14 CCR Section'' 15300.2 apply, thereby negating categorical exemption of the project.

Explanation: I Yes n n 0 Mavbe No The proposed project is not anticipated to result in significant air quality impacts. Placement of final cover as proposed in the project provides an effective mitigation of existing potential landfill gas impacts by reducing air and water contact with the waste (Bonaparte 1995; US EPA 1993; and US EPA 1991). Air and water contact with waste can create adverse environmental impacts by facilitating the release of landfill leachate and gas. Landfill gas releases can cause explosion hazards, odors, and human contact with potentially toxic trace gases. Additional landfill. gas control is included in the proposed project by incorporation of the site's existing landfill gas control system within the final cover. No significant additional vehicular or equipment air emissions over what is currently in place for the ongoing active landfill operations is anticipated because only onsite borrow sources for final cover soil are used and no significant additional equipment will be used beyond what is normally osec' the active landfill operations.

The proposed project consists of placement of soils from onsite cover borrow sources over incremental phases of waste fill areas that have been brought to final grades. Drainage and erosion control required for the operating landfill pursuant to 14 CCR 17708_ would apply to the proposed project. Surface drainage and erosion" control measures for final cover phases and borrow areas are incorporated into the drainage control system for the ongoing landfill operation and specified in the Partial Final Closure and Postclosure Maintenance Plan. Drainage and erosion control standards for final cover are more stringent than for an operating landfill without final cover. Therefore, the proposed project would enhance protection of surface waters. Construction of final cover reduces potential percolation of rainfall through the existing waste fill. Percolation through the waste fill can produce leachate which can potentially contaminate ground water. Therefore, the proposed project would be beneficial in protection of ground water quality. Based on ground water conditions in the area, the proposed project would not alter ground water beneficial (uses or result in significant changes to ground water flow. No significant impacts on surface or ground water are anticipated. Substantial or potentially substantial adverse change: Yes Mavbe No 1V. Plant Life Will the project will result in: a. Change in the diversity of species, or number of any species of plant (inch 1 g trees, shrubs, grass, crops, and aquatic plants)? ❑ b: Reduction of the numbers of any unique, rare, or endangered species of plants? c. Introduction of new species of plants into an area, or in a barrier to the normal replenishment of existing species? d. Reduction in acreage of any agricultural crop? e. Deterior habitat? of existing plant n U 0 co 0 Page 4 Attachment 1- Initial Sfudv Checklist BKK Landfill Partial Final Closure and Postelosure Maintenance Plans Explanation: The proposed project consists of placement of soils from onsite cover borrow sources over incremental phases of waste fill areas that have been brought to final grades. Onsite borrow sources used for final cover are the same as used for daily cover which is part of the ongoing landfill operations. Landfill gas extraction and control systems are then constructed within the final cover phases and incorporated into the existing landfill gas extraction and control system which.is required for ongoing operations. Shallow rooted vegetation is then established by hydroseed and maintained to provide erosion control and prevent penetration and damage of the final cover. Vegetation specifications are provided in the Partial Final Closure and Postclosure iNIaintenance Plans and are similar to those used for final closure of the Class 1/III area which was completed in 1989. No significant impacts on plant life are anticipated because the site has previously been excavated, filled, compacted, and graded as part of the ongoing active landfill operations and no new areas will be disturbed for the proposed project. In addition, the site is not utilized or zoned for agricultural land. . Substantial or potentially substantial adverse change: Yes Mavbe No V. Animal Life Will the project will result in: a. Change in the diversity of species, or number of any species of animals (birds, land animals including reptiles, fish and shellfish, benthic organisms or insects)? ❑ ❑ b. Reduction of the numbers of any unique, rare, endangered species of animals? ❑ ❑ C. Introduction of new species of animals into an area, or result in a barrier to the migration or movement of animals? ❑ ❑ d. Deterioration of existing fish or wildlife habitat? ❑ ❑ Explanation: No significant impacts on animal life are anticipated because the site has been previously excavated, filled, compacted, and graded as part of the active ongoing landfill operations and no new areas will be disturbed for the proposed partial final closure project.

Possible interference with an emergency response plan or an emergency evacuation plan? ❑ ❑ Explanation: The proposed project does not involve any use of potentially hazardous substances other than oils and fuels which are used for construction equipment operation. No significant additional equipment will be used for the proposed project beyond what is used for the active ongoing landfill operations. Emergency response required for the active ongoing landfill operations pursuant to 14 CCR 17638 and 17696 would apply to the proposed project. The proposed project would be covered by the existing Emergency Contingency Plan which is contained in the Partial Final Postclosure Maintenance Plan and Report of Disposal Site Information. Therefore, -no significant impacts in these areas are anticipated. Substantial or totentially_substantial adverse chanee: I Yes Mavbe No Transportation/Circulation Will the project involve: a.

Site security for the active landfill required pursuant to 14 CCR 17658 would apply to the proposed project. Site security measures in place to prevent uncontrolled access include a chain link periimeter fence and 24-hour surveillance by security guards and/or landfill operations and maintenance staff. No additional vehicular traffic over what is currently in place for the active landfill operations is anticipated because only onsite borrow sources for final cover soil are used and no significant additional equipment 'will be used for the proposed project beyond what is used for the active landfill operations. Traffic control for active landfill operations required pursuant to 14 CCR 17659, 17660, and 17714 would apply to the proposed project. Specific traffic control measures are included in the Report of Disposal Site Information. Therefore, no significant impacts to transportation/circulation are anticipated.

Exposure of people to severe ❑ O noise levels? Explanation: The proposed project includes no significant additional use of construction equipment beyond what is used for the active ongoing landfill operations. Noise abatement mufflers have been installed on ally heavy equipment used at the facility and hearing protection is provided to the equipment operators and other site personnel to further mitigate the potential for occupational noise related hazards. Noise control for the active landfill required pursuant to 14 CCR 17712 would apply to the specific project. Specific noise control measures are specified in . the Report of Disposal Site Information. Therefore, the proposed project will result in no increase in existing noise levels or exposure of people to severe noise levels. Substantial or potentially substantial adverse change: XIV., Public Healtti & Safety Will the project involve: a. Creation of any health hazard or potential health hazard (excluding mental) health)? b. Exposure of people to potential health Explanations Yes Mavbe No ❑ ❑ IN The proposed project will not result in creation of a health hazard or exposure of people to . a potential health hazard. The proposed project is within an active landfill facility. The facility is restricted to public access and site security measures are in place to prevent uncontrolled access. Placement of, final cover as proposed in the project provides short and long term beneficial effects on environmental conditions at a landfill by reducing potential air and water contact with the waste (Bonaparte 1995; US EPA 1993; US EPA 1991; and CIWMB 1990).. Air and water contact with waste can create adverse environmental impacts by facilitating release of landfill leachate and gas. Leachate releases can contaminate surface and ground water which can then adversely affect public health and safety. Landfill gas releases can cause explosion hazards and human contact with potentially toxic trace gases.

Aesthetics a. Will the project result in the'i obstruction of any scenic vista or view open to the public, or will the proposal result in the creation of an aesthetically offensive site open to the public view? Will the proposal produce new light',or glare? ❑ ❑ Explanation: The proposed project is not anticipated to result in significant impacts in the area of aesthetics. The projected final grades in the Partial Final Closure and Postclosure Maintenance include -an approximately 58 acre top deck area constructed with a minimum slope of 3% and maximum elevation of 1050 feet above mean sea level (MSL). The existing maximum height of the. closed Class I/III area is also 1050 feet MSL. Postclosure settlement is expected to reduce the maximum',height of the waste fill. The current maximum elevation (December 1995) of the ongoing active landfill operation is approximately 1000_ feet MSL. No new light or glare is anticipated because the final cover will be composed of earthen materials. Substantial or potentially substantial adverse change: Yes Mavbe No XVI.

Yes No Summary of Fit explained herein, 11 Based on study findings as ion is made for the following conclusions: a. Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below Iself sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant Page 12 Attachment 1- Initial Study Checklist BKK Landfill Partial Final Closure and Postclosure Maintenance Plans or animal or eliminate important examples of the major periods of California history or prehistory? o b. Does the project have the potential to achieve short-term, to the disadvantage of long-term environmental goals? 4 o C. Does .the project have impacts %vhich are individually limited, but cumulatively considerable? o d. Does the project have environmental effects which will cause substantial';adverse effects on human beings, either directly or indirectly? o e. Do the activities of this J ro'ect have an influence P on recreation, aesthetics, noise, cultural resources, or any other environmental issues which have not been included in this checklist? Determination of Significant Effect On the Basis of This Initial. Evaluation (check one): I find that the proposed project COULD NOT have a significant effect on the environment or significant cumulati� a effect on the environment. The exceptions pursuant to 14 CCR Section 15300.2 do not apply and .. therefore do not negate categorical exemption of the project. i` I find that the proposed project COULD NOT have a significant effect on the environment and a NEGATIVE DECLARATION will be prepared. I find that, although the proposed project could have a significant effect(s) on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A NEGATIVE. DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, ENVIRONMENTAL IMPACT REPORT is required.

Landfill, Class III Disposal Area. The LEA's comments included by reference comments provided by the public and City of West Covina. Response is provided for all comments compiled during the review process. The purpose of this response is to facilitate approval of the Plans and resolution of closure and postclosure issues at the BKK Landfill. A separate request will be transmitted to BKK based on this response for revisions to the Plans necessary _ for the LEA's approval. The LEA has indicated that BKK has not revised Preliminary and Partial Final Plans to reflect the LEA's comments. + Denial of closure and postclosure plan approval by the LEA requires a written record of the specific detailed circumstances for denial pursuant to Section 18271(a) and (b) of Title 14, California. Code of Regulations (14 CCR),, Division 7, Chapter 5. BKK submitted a general response on September 27, 1995 to the LEA's comments. BKK indicated in their response that they had reviewed and considered the. LEA's comments and had responded fully to all concerns of the CIWMB. BKK further indicated that the majority of LEA comments were not relevant to final review and approval of the Plans. I The Los Angeles Regional Water Quality Control Board (RWQCB) approved the Preliminary and Partial Final Plans on March 29, 1995. By letter dated September 29, 1995, CIWMB staff indicated they were prepared to.proceed with final approval and that the LEA's forthcoming approval was anticipated.

BKK has clearly mentioned that this plan does not address the ultimate development, therefore a determination needs to be made on the validity of this document per the intent of the regulations. If local land uses issues on the ultimate development of the site are still unresolved, what planning purposes does this serve? 4-1 Section 4.1- Refer to comments above Page 1-1 1.1 Page 4-2 Section 4.1- The CIWMB did not request BKK to submit a Partial Final Closure Plan. BKK proposed this plan as part of an agreement with the LEA to comply with the Solid Waste Facilities Permit Revision Notice and Order. i Page 4-4 Section 4.1- How accurate and valid is this document without 'the final grading plans established for the entire landfill? CIWNM Response: Submittal of Final Plans for complete site closure is premature at this (1) time until resolution of the litigation regarding the .final closure date. In addition, postclosure land use development and local landscaping and grading plan issues will also need to be resolved. However, closure and PO stclosure maintenance plans are required to be in the operating record to meet the requirements of 14 CCR 17258.65.� Submittal of Partial Final Plans for the ongoing final cover placement as portions of the site reach final grade and Preliminary Plans for complete site closure meets this requirement and provides'a basis for future resolution of issues I the permitting process and final site closure. Concerns have been expressed regarding the Partial Final and Preliminary Plans authorizing or sanctioning site operations, grading, and closure dates which are under dispute. This concern is unfounded. Preliminary closure/postclosure plans solely address conformity with 14 CCR closure/postclosure regulations and cannot be implemented. The Partial Final Plans specifically address placement of final cover as the site progressively reaches final grades, pursuant to 14 CCR Section 17764(b)(1).

LEA Comment: Page 6-5 Section 6.2.3- BKK should demonstrate why they assume leachate extraction to be complete in 21 years. CIWMB Response: This comment refers to primarily a water quality aspect which is under (11) the purview of the Los Angeles Regional Water Quality Control Board (RWQCB). The RWQCB approved the Preliminary and Partial Final Plans on March 29, 1995. However, it is reasonable to assume for the purposes of Preliminary Plans that leachate production would significantly decline several years after complete site closure. Furthermore, Attachment 1 of the Partial Final Plans includes a water balance analysis which supports this projection. No further response or changes to address this comment are necessary at this time. x LEA Comments- Partial Final Closure Plan LEA Comment: Page 1-1 Section 1.1- The closure date on the lifespan of the site has not been determined. Closure plans and cost estimates are based on closure dates. How accurate are the cost estimates if there is no certainty on a closure date? There should be.some determination by the agencies' review as to what elements in this plan are directly related and impacted on a definite closure date for planning purposes and. then how these issues should be handled Page 1-2 Section 1.2.- It is my understanding that there are no final closure and postclosure maintenance plans submitted because of no date of certainty for closure of the facility.

LEA Comment: Page 3-1 Partial Final Closure Plans are to be submitted to agencies for their approval prior to the implementation of closure activities. BKK has stated here; that they have implemented closure improvements in 1992, 1993, and I994 on area A drawings 1 and 2. They are late in submitting partial final closure plans for our rey:ew when all the work has already been completed. Why weren't the agencies notified of this? It appears that BKK: has circumvented the regulations here. 1 question now the credibility, of their work without agency oversight. An independent third party should be hired by the CIWMB and financed by BKK to review and validate all work completed to date prior to any approvals. It makes it awfully Jiff cult to incorporate any additional requirements when BKK has completed everything. What happens if the final cover design has more stringent requirements such as additional clay and vegetative layers?

(ls) Cv ti4.?e:eQ t :-i o. •ems rr �areas �.. CQ'• S':S� s duce in �rtu .ajerc,, revie'.v of 2'� 's iverk is after the fact. The comment questions the appropriateness of accepting final co-,-er work that was completed prior to submittal of the Partial Final Plans. While approval of Partial Final Plans prior to completing the work is preferred, the approach presented in the Partial Final Plans is reasonable given the site specific situation. The BKK Partial Final Plans specifically address placement of final cover as the site. progressively reaches final grades. The BKK Landfill has been implementing these activities since 1992 as prescribed in the Solid Waste Facilities Permit, Unclassified Use Permit No. 71 Revision 5 Amendment (Items 4.E., I I.F., and 25), and Waste Discharge Requirements (WDRs) Order No. 87-39 (Finding 22). Final cover placement as the landfill reaches final grades is clearly of environmental benefit given that the minimum standard for intermediate cover provides substantially less containment. Intermediate cover could be placed equivalent to final cover standards without violating 14 CCR minimum standards. However, sanctioning as final cover through the Partial Closure Plan review and approval- process ensures that the cover is constructed to the highest possible standards promptly as the site is filled and does not require reconstruction upon complete site closure. Note that CIWMB staff have reviewed construction quality assurance I ;(,CQA) test data prepared by BKK's CQA contractor and have determined this information is sufficient to address compliance,":Mth 14 CCR Sections 17773 and 17774'.' Reconstruction of work completed so far is not required. An independent third party hired by the CIWMB to �eview and validate all work completed to date is therefore not necessary. In addition, BKK's final cover design substantially exceeds the containment afforded by the minimum prescriptive standard (3' minimum monolithic barrier/vegetative layer with permeability _<1 x 10,6 cm/sec as compared. with the minimum prescriptive standard of 1' vegetative layer permeability unspecified overlying 1' barrier layer with permeability 51 x 10,6 cm/sec). A more stringent design is not necessary at this time but may be incorporated for complete site closure depending on the final postclosure land use. o further address the LEA's comments, CIWMB staff will request that • • Final Workin' Draft- November 2, 1995 Page -12 Responses to City of West Covina LEA/Plarning and Building Department Comments BKK Landfill Preliminary and Partial Final Closure /Postclosure Plans the following sentence', be added to paragraph 2 of Section 3 : LEA Comment: Page.4-1 Section 4.1.2- No reference should be made to another document to address security.

BKK admits that the full cost estimates have not been provided for the entire landfill. Therefore the cost estimates should be deemed inadequate and unacceptable.

Response: Closure/postclosure cost estimates for the entire landfill are contained in (25) the Preliminary Plans ;and are not necessary for the Partial Final Plans. The cost estimates meet 14 CCR Article 3.4 requirements. Cost estimates for LEA inspections and monitoring are not required per 14 CCR Article 3.4 and are addressed for the Partial Final Plans as per active site inspections; Reimbursement of LEA's costs should be negotiated separate from the closure/postclosure plan review and approval process between the LEA and operator upon final site closure.

CIVIMB Response: The Emergency Response Plan is adequate for approval of Partial Final (37) Plans but should be updated as necessary and incorporated as a revision or amendment to the Preliminary and Partial Final Plans, and incorporated in Final Plans for complete site closure. It may be helpful to solicit input from local fire, police and OES on the Emergency Reponse Plan but-specific approval by these agencies is not required.

What is the "Ancillary Storage Area" on the west sided of the site and the southerly ridge line used for? The water reservoir shown at the northeast corner of the site requires approval of a revision to the MDP; The location of the reservoir will need to be screened from views with berming and/or landscaping.

This is not shown nor are the effects of such grading or the maintenance of this slope addressed in these documents. The finaUultimate cut slopes on the west and north side of the landfill exceed the maximum 2:1 slope limit in the UUP. Plan 6- The North Area step out shown on the plan violates the UUP and the MDP. Plan 12- The plan fails to show the slope created along the north ridge line and drainage that would occur from its creation. Plan 16 Section 2125 show that the ultimate cut slope to the west of the landfill will exceed thIe maximum slope provision in the UUP of 2:1. Public Works The discussion of pages 4-12 through 4-17 does not mention that the Comments: grading and drainage will comply with City and County requirements. The final grading plan must be submitted for City checking and approval. The final drainage plan (storm drains) must be submitted for City and County checking. and approvals. The site hydrology must be submitted for City and County checking and verification ,'Ian No. 4 is lacking in significant details and is, at best, a "conceptual" plan. Even at that, it does not comply with the City's Grading Ordinance. I The discussion in 4.7 does not conform to the City's Grading Ordinance. CIW'NS Response: The Preliminary Plans acknowledge that the MDP is subject to (50) resolution of ongoing issues of dispute between the City of West Covina and BKK. These issues mainly include final closure date, postclosure land use, local landscaping, and grading but also includes the North Step out Area. The Preliminary and Partial Final -Plans must be amended or revised to reflect resolution of these .issues until Final Plans for complete site close I are submitted. This would be required pursuant to 14 CCR 18272 andl 18276.

Planning Comment: Page 2-5 Section 2.2.2 - The completed excavation slopes cannot exceed amaximum of 2:1. CIWMB Response: The issue of'maximum slopes for excavations has been brought up in (54) several Planning and Public Works Department comments. The UUP (Amendment) indicates ultimate slopes to be constructed in accordance with the City Grading Ordinance to a maximum slope of 2:1 (horizontal:vertical) (Sections 4. EA and 24.D.). All waste fill slopes meet the maximum criteria of 2:1. However, the Partial Final Plans • • Final Working Draft- November 2, 1995 I Page -28 Responses to City of West Covina LEA/Planning and Building Department Comments BKK Landfill Preliminary and Partial Final Closure/Postclosure Plans conf= (page 2-5 section 2.2.2 and Plan 3) that existing excavations in certain borrow areas have slopes up to 1.5:1. Based on review of City Drainage and Grading Ordinance (Article 1, Ord. No. 1938, § 2 adopted June 7, 1994), CIV;NB staff see no explicit preclusion of cut slopes steeper than 2:1. The City Drainage and Grading Ordinance incorporates by reference portions of the Uniform Building Code (UBC)I which can provide more detailed information to clarify appropriate cut slope requirements. The 1994 UBC states the following under Section 3312- Cuts: Section 3312.2 Slope. "The slope of cut surfaces shall be no steeper than is safe for the intended use and shall be no steeper than 1 unit vertical to 2 units horizontal (50% slope) unless the permittee furriishes a soils engineering ' or an engineering geology report, ' or both, stating that the site has been investigated and given an opinion that a cut at a steeper slope will be stable and not create a hazard to public or private property." _ Although provisions issue should be adds Final Plans as part c issue sh,, :.ld be incc requesed, CIWMB and City on BKK L Preliminary and Par )r cut slopes steeper than 2:1 are allowed for, the ,sed separate from the Preliminary and Partial, ongoing landfill operations.

Instead the documents present what may be in the future. This preliminary plan was to address "what is" and let "what may be" to the final closure plan. Much of what is presented is done by BKK to confuse the public on the issues at the Landfill. Even the first version of the Class I Closure Plan for the BKK*Landfill was better. At that time, we were all entering new territory with the Class I Closure Plan. I Page N. Includes the North Area Expansion Proposal that does not comply with the City's Unclassified Use Permit (UUP) and violates the approved Master Development Plan (MDP) for the Landfill. This ezpansion must have City approval as an amendment to the UUP and MDP. BKK has failed to file an application as requested. City is considering enforcement actions to gain compliance. oughout documents BKK refers to Class VClass III Landfill, Class Landfill, and Class I Landfill.. The discussion in text bounces back 1 forth between these three options. Needs to be reviewed and ised to be made very clear. The solid Waste Facilities Permit is for whole site, although not all of the site can be used for waste posal. This is the same case for the Interim Status Document for zardous Waste disposal, the Waste Discharge -Requirements and the v's Land Use Permit. Iso, the discussion in text is incomplete if the document is to discuss to full landfill site, not just the Class III unit. Several examples will allow in the detailed comments below. This needs to be accurate or the ublic will be confused and the CIWMB will be approving a document iat is ripe for a variety of interpretations as it suits the interpreter. Page 1-3, Paragraph S: Grading plan covers the Class III unit. Nearest homes are the townhouse in Montera Point, north of the Class III Landfill Disposal Unit. The proposed townhouses could be 300 feet from fill. 11 • Final Working Draft- November 2, 1995 Response to Public and City of West Covina BKK Landfill Prelirzinary and Partial Final C Comments ;losure./Postclosure Plans Page -30 Page 1-3, 1.2.3: Class III unit includes North Area Expansion that has not been approved by the City.

Paragraph 3:. 1993 kDP proposed by BKK' was reflected by the City in July, 1993 as being 'inconsistent with other BKK plans and other agencies' requirements. Thus their 1993 submittal has no credence here and elsewhere in this 'document. No mention of San Gabriel Valley Corporate Center anywhere in this document. i Table 4.1 should be rye -computed to exclude North Area Expansion. CIWMB Response: These comments have been addressed in above CIWMB Responses #38, (56) #39, #40, #49, #50, and #51. Regarding the terms Class I, Class MI, and Class III Landfills, CIV MB will request that BKK revise Section 1.1 to clarify the description and use of these terms and revise all references to the terms as necessary to improve consistency. Based on discussion with RWQCB staff, the Class MII landfill includes separate Class I and Class III areas that were overall subject to closure as a discrete Class I waste management unit. City Comment: Pages 1-5, to 1-8: Chronology is incomplete and inaccurate. BKK knows the. chronology, or should know it as well as anyone. They do not have anyone on staff that goes back to the '70s', however they have the ability to examine the Class I Closure Plan to improve the chronology. Even the chronology used by the City for public information (attached) is more complete. This chronology was reviewed by BKK when it was first produced. It has been reported that BKK records are in a less than desirable condition to provide a historical perspective. More than once over the years, BKK has come to the Cityfor records they should alreadv have in their files.

Since these !plans may serve to fulfill this statutory requirement, preparation of a separate document, for this purpose, may not be necessary. It is our opinion that based on what these plans contain a full CEQA review is required BKK has elected to include in these plans: 1. The North Expansion. 2 The 1993 MDP they submitted to the City. 3. The removal of the west and south ridge lines in violation of the approved AdDP for the site. 4.

As stated ear"er, the Clos�a6 ar:d bostclosure plans are to address "what is, " not "what will be. " As Iona, as BKK insists these plans address "what will be, " this constitutes a new project under CEOA. Therefore, a full environmental review must be conducted. If BKK removes all of these items from the closure and postclosure plans and only addresses "what is" then there may not be a need for a CEOA review. CIPKVfB should require BKK to only include in their plans those items that have the approval of all agencies to do on the site.' This includes the City of West Covina. CIWMB Response:. Concerns have been expressed regarding the Partial Final and (77) Preliminary Plans authorizing or sanctioning site operations, grading, and closure dates which are under dispute. This concern is unfounded. Preliminary closure/postclosure plans solely address conformity with 14 CCR closure/postclosure regulations and cannot be implemented. The Partial Final Plans specifically address placement of final cover as the site progressively reaches final grades, pursuant to 14 CCR Section 17764(b)(1). BKK has been implementing these activities since 1992 as prescribed in the Solid Waste Facilities Permit, Unclassified Use Permit No. 71 Revision 5 Amendment (Items 4.E., 11.F., and 25), and Waste Discharge Requirements (WDRs) Order No. 87-39 (Finding 22). Final cover placement conducted so far has been in compliance with State Minimum Standards for protection of public health and safety and the environment. The Partial Final .Plans do not sanction or authorize. site configurations which will not be authorized and only address implementation of individual closure activities that involve negligible or no expansion of use beyond that previously existing. In addition, the Preliminary and Partial Final Plans must be amended or revised as necessary to reflect resolution of ongoing disputes and any permit changes, until final closure/postclosure plans for complete site closure are submitted. This would be required pursuant to 14 CCR 18272 and 18276. Because they address activities which involve negligible or no expansion of use beyond that previously existing, approval of the Partial Final Final Working Draft- November 2, 1995 Response to Public and City of West Covina Comments BKK Landfill Preliminary and Partial Final Closure/postclosure Plans City Comment: CIWMB Response: r'(/! pO) Page -50 Plans by CIV;N[B and the LEA would be exempt from CEQA pursuant to 14 CCR Section 15301 (Class I Exemption). Although approval would be exempt from CEQA, extensive environmental review and consideration of comments from the public and public agencies has been incorporated in the closure/postclosure plan review process. In addition, any permit action would be subject to a separate CEQA review as appropriate. The Notice of Public Comment indicates the other agencies that have been notified to provide comment. Notable by their absence from this list is the US Environmental Protection Agency. The full 583-acre site is under a USEPA enforcement order. The same site is under an Interim Status Document for Hazardous Waste Disposal. The USEPA is certainly a responsible party when it comes to theregulation of this site. Prior to the CIWMB taking any actions, preliminary or final, on the Closure and Postclosure Plans, the USEPA must be given ample time to review and comment on the documents. Of particular concern is the relationship between the Class III and Class I disposal units. CIWMB has notified and consulted extensively with agencies during the Preliminary and Partial Final Plan review process.

CI`VNIB Response: Section 1.3.1 (Facility History) is being requested to be deleted from the (80) Preliminary Plans. Public Comment: Page 1-10, Paragraph 5: Daily disposal cell unit described here could receive more than 13, 000 tons per day if one uses: the described size of the daily disposal cell the compaction rate of trash used by BKK the weight of trash per cubic yard. Provide a realistic description of a daily disposal cell based on 12,000 tons per day and reasonable assumptions. Describe the assumptions. Page 1-11: Other special wastes are not listed. Should be a complete list of these wastes and locations of disposal if appropriate. It would be ;appropriate for asbestos. ;Page 2-10, 2.2.4, Paragraph 1: Define the word "near"as used.in this section. There were homes southwest of Amar and Azusa before the landfill started operation. These homes were within 1, 800 feet of the Landfill property. Other homes were -within 2, 000 feet northwest. of the site. This needs to be clarified and reflected in the text and maps of this document. CIWMB Response: j Section 1.4 is not intended to be a detailed description of landfill (81) operations and is sufficiently detailed for acceptance as part of Preliminary Plans. Sections 2.2.4 is not intended to be a detailed description of surrounding land use before the landfill started operation j and is sufficiently detailed for acceptance. Public Comment Page 2-25: There is groundwater contamination off -site in several areas adjacent to the Landfill. This needs to be described in this document. Final Working Draft- November 2, 1995 Page -52 Response to Public and City of West Covina Comments . BKK Landfill Preliminary and Partial Final Closure/Postclosure Plans Page 2-26: There are plumnes of contaminated groundwater abutting and from the Landfill. CIWMB Response: These comments refer to water quality aspects which are under the (82) purview of the Los Angeles Regional Water Quality Control Board (RWQCB). The RWQCB approved the Preliminary and Partial Final Plans on March 29, 1995 and is providing State oversight on the ongoing ground water and leachate monitoring and control for both the Class III and Class I Landfills which will continue during postclosure. Public Comment: Page 3-9: Any mention of the methanol production plant is premature. CIWMB Response: The Preliminary Plans adequately reflect that the potential future (83) methanol production plant has not been approved. , Public Comment: Page 340, 3.3.5, Paragraph 2: Questioned BKK's retention of records for three years. What is the requirements and what records are retained? OWNS Response: Monitoring reports are required to be submitted to regulatory agencies. t (84) The agencies will retain reports in their public files. CIWMB staff are not aware of any specific requirement for time periods of on -site retention of the landfill gas collection system monitoring report records. Public Comment: Page 3-13: What is the surface emissions monitoring frequency? CIWMB Response: Surface emissions monitoring is conducted on at least a quarterly basis. (85) Public Comment: Page 4-1: BKK's approved MDP allows more disposal capacity, but it does not reflect the changes and occurrences since 1974. For example, the 1974 MDP did: not have a separate Class I disposal unit from the Class III disposal unit.- CIWMB Response: The MDP is part of ongoing disputes between the City of West Covina (86) and BKK. Upon resolution of the disputes, the Preliminary and Partial Final Plans must be amended or revised in accordance %krith 14 CCR 18272 and 18276, and final plans for complete site closure developed. • F ,nal �;� or'.cin_ 1 r a..- No : e: ccr _. ; y�i � Pa=e -51 R�sonse to P.'-iic a.^^.c'_ C;-!; c �,�'_st Cc�ina Cct~ents B:K Lan', •' °:e!;;-,'r�^ nd P :.-tial Final C'csu:�'Postclost:re Plans .u:li1 . ,:i .

Minor revisions will, be requested to reflect comments from the City of West Covina LEA and Planning Departments. They will require updating as necessary for incorporation in final plans for complete site closure. Public Comment: CIWMB Response: (88) The MDP is- a major part of the ongoing disputes between the, City of West Covina and BKK. Upon resolution of the disputes, the Preliminary and Partial Final Plans must be amended or. revised in accordance with 14 CCR 18272 and 18276, and final plans for complete site closure developed. There is off -site groundwater contamination north, south, southeast and west of and from the Landfill. These comments refer to water quality aspects which are under the purview of the Los Angeles Regional Water Quality Control Board (RWQCB). The RWQCB approved the Preliminary and Partial Final Plans on March 29, 1995 and is providing State oversight on the ongoing ground water and leachate monitoring and control for both the Class III and Class I Landfills which will continue during postclosure. Final Working Draft- November 2, 1995 Page -54- Response to Public and City of West Covina Comments BKK Landfill Preliminary and Partial Final Closure/Postclosure Plans Composite Comments from the Commission Commission What is the real capacity of the Landfill in tons, cubic yards and years Comment: without any expansion to the north, west, or waste disposal in the 'wedge'. Page 4-11: There is concern that the only cover for the landfill is from all.of the ridge lines The removal of the ridges to the west and south and north of the Class I disposal unit is in violation of the approved 1974 MDP for Landfill site. CIWMB Response: Upon resolution of ongoing issues dispute between the City of West (89) Covina and BKK, revision or amendment of the Preliminary and Partial Final Plans is required and must be incorporated in final plans for complete site closure. Among these issues are grading and site closure date which will trigger revision of capacity calculations. Commission Page 3-9: Need to estimate the landfill gas to be produced in the Class Comment: III disposal unit and place it in the context of the gas produced from the Class I disposal unit. According to the SCAQMD flare variance the t amount of gas produced from the Class I is 17-18, 000 CFM. Project the amount to be produced from the Class III. Evaluate the adequacy of the flares, turbines and electrical generating facilities to use this volume of gas. Page 4-7: According the BKK's plans, the flares and electrical generators will use all of the collected gas at the Landfill. There needs "to be documentation on the -gas pr.o.Iuced (Class 1, Class III and total) and the amount of -gas used by flares, turbines and electrical generators.. We remember BKK's application to the Cityfor a third flare station. CIWMB Response: CI YNINM staff have reviewed gas collection and control information (90) provided in the Preliminary and Partial Final Plans and have determined that this information meets regulatory requirements and is sufficient for approval. Gas production capabilities presented are sufficient at this time to address closure and postclosure maintenance. Revised calculations would be warranted to support proposals for expansion of production capabilities. e r r1^a; �.� art - ^�^�' �. 1 1�1a� pa"' and' C:L, o %VSt Coy: ;::a C.):� --Zs B.L:K L=d:-. and Par•iat Fira' C!c:urt;Postclosure Plans a.

The comment just restates the regulation of 14 CCR 17773. Page 4-9? Insurance that is listed in the documents is not adequate for a 30 year maintenance. It does not comply with the underlying land use permit requirement for maintenance in perpetuity. CIWMB needs to have any insurance policy comply with that requirement. The financial assurance is not an insurance. policy. It does not appear to be. an adequate amount. It has not been approved by CIWMB. In accordance with 14 CCR 17788, the postclosure maintenance period is a minimum of 30-years and will continue as long as the site poses a threat to public health and safety or the environment. The financial assurances mechanism for closure and postclosure maintenance meets 14 CCR requirements and has been approved by CIWMB. If the financial mechanism is not maintained as approved, the operator would be in violation of 14 CCR 18282 and 18283 and would therefore be subject to enforcement action by OWNS and the LEA.

Irrigation will be needed for several of the listed plant species a ter the five years specified in the Plans. Several of the plants will not "naturalize" in. the five years or any time thereafter. Some of the plants need extensive irrigation. Other -plants have a very expansive root system that kills other plants and offspring for the parent plant within the lateral radius of the parent. Other plants appear to, be drought tolerant. This could mean their roots go deep and could penetrate the landfill cover.

OF WEST COVINA FOR FURTHER INFORMATION CONTACT: Steven W. Wylie, Assistant City Manager (818) 814-8401 FOR IMMEDIATE RELEASE CITY OF WEST COVINA AND BKK CORPORATION ANNOUNCE SETTLEMENT OF LITIGATION-- BKK LANDFILL TO CLOSE NO LATER THAN SEPTEMBER 15,1996 Officials of 'the City of West Covina and the BKK Corporation on Wednesday, January 17, consented to a judgement in the lengthy litigation between the parties over the closure date of the BKK Landfill. The judgement establishes September 15, 1996, as a firm and binding closure date for the BKK Landfill in West Covina, although officials from both parties are optimistic that the facility could cease the receipt of waste as early as June 30. 1 "This is a momentous day for West Covina," announced Mayor Steve Herfert. "It marks the .beginning oft I e end of a most difficult time for the City, its residents, and the BKK Corporation. With the settlement of this litigation, we are on the road to a firm closure date, one that wi 1 11 keep this landfill closed forever. In addition, a separate letter agreement paves the way for a responsible closure, which will enable BKK to develop its periphery with ap ropriate uses while requiring the landfill slopes to be landscaped much more extensively than would otherwise have happened." The judgement pertains only to the litigation over the enforceability of the 1985 Memorandum of Understanding (the MOU) between the City and BKK, which established a closure date of November 1995. The parties had argued over the enforceability of that document. Several attempts to settle the litigation proved futile, and 1444 W. Garvey Avenue, Post Office Box 1440, Wcst Covina,. California 91790 the trial resumed agreement during 'News ele'ase CITY OF WEST COVINA January 16 before Judge William Drake. The parties reached negotiations that lasted into the following day. I' Still to be resolved are several separate .pieces of litigation between the City and BKK over such things as disputed business license taxes and a suit brought by BKK against the City alleging violation of the corporation's civil rights. The judgement in the MOU case requires the BKK Corporation or any successor to "permanently cease accepting any waste for handling, transfer, recycling, disposal, landfilling, or any other related activities at the BKK landfill by no later than September 15, 1996." It permits BKK to continue to mitigate landfill gas and leachate connected with past operations of the landfill, to use reclaimed or recycled water on the site, and to receive non -contaminated soil from off -site sources to be used for final landfill cover. In addition, the judgement decrees that the City's Unclassified Use Permit will be revised and/or amended t10 reflect the closure date and other limitations contained in the judgement. Lastly; the judgement will be recorded and run with the land, preventing the site from reopening for waste disposal activities by BKK or any other party at any time in the future. Along with the judgement in the MOU litigation, the parties have approved a separate letter agreement providing viding a framework for the ultimate closure of the 583 acre site. The agreement gives BKK the right to grade certain slopes adjacent to Azusa Avenue to create developable{pads for future commercial use as well as the creation of sufficient soil for daily and final i over until the closure date. 1444 W. Garvey Avenue, Post Office B x 1440, West Covina, California 91790 CITY OF WEST COVINA The right to grade in this agreement is conditioned upon the provision of satisfactory proof that sufficient soil.exists not only for daily and final cover, but also to provide a much deeper layer for enhanced landscaping to occur on the existing landfill slopes. This landscaping is designed to replace the grass cover currently seen on these slopes and will more closely resemble the landscaping at other sites such as Puente Hills. BKK is required to submit the landscaping plan by April 1, 1996, and the landscaping must be commenced in phases as the landfill itself closes.
