INSURANCE REQUIREMENTS L: \projeet\385 \Ukiah.agr DATE: NOV 1/, /99Z SCOPE OF WORK CITY OF UKIAH LANDFILL TASK I - ARTICLE 5 MONITORING PROPOSAL The City of Ukiah is seeking assistance in preparing the Water Quality Monitoring Program and Assurance of Financial Responsibility for the City of Ukiah landfill in compliance with revised Title 23, Chapter 15, Article 5 of the California Code of Regulations (revised Article 5). On June 1, 1991, the State of California promulgated a revision to Article 5, which requires operators of Class II and Class III Waste Management Units (WMUs) to (1) submit a technical supplement to the existing Report of Waste Discharge (RWD) that meets new environmental monitoring performance standards (i.e. the development of a more comprehensive water quality monitoring program), and (2) to establish and maintain assurances of financial responsibility for potential corrective action for "all known or reasonably foreseeable releases" of waste constituents. Fundamental to the development of a Water Quality Monitoring Program and an Assurance of Financial Responsibility, a clear understanding of the geology, hydrogeology, and geo- chemistry of the landfill sites is required. We understand that a significant amount of geo- logic and hydrogeologic work has been completed at the City of Ukiah Landfill site, includ- ing extensive chemical analysis. Based on this understanding, EBA has developed a scope of work for: o Developing a revised Water Quality Monitoring Program for the landfill in accordance with Section 2550.0 (a) of revised Article 5. o Developing a cost estimate associated with implementing corrective action for a reasonably foreseeable release from the landfill site in accordance with Sec- tion 2550.0 (b) of revised Article 5. EBA has divided the Article 5 work into two principal subtasks corresponding with these requirements. The scope of work takes into account the geologic, hydrogeologic, and geo- chemical work completed to date at the landfill. I.A - DEVELOP MONITORING PROGRAM Three types of water quality monitoring programs and associated performance standards are described in §2550.0 through §2550.12 of revised Article 5. These are: o detection monitoring [ §2550.7] o evaluation monitoring [ §2550.9] o corrective action [ §2550.10] L: \project \385\Ukiah.agr These monitoring and response programs apply to the three media (groundwater, surface water, and the unsaturated zone) for which monitoring is required under revised Article 5. Detection monitoring must be conducted during the active life of the WMU, throughout closure, and well into the post- closure maintenance period. The purpose of a Detection Monitoring Program is to "provide the best assurance of the earliest possible detection of a release from the waste management unit" [ §2550.7(b)(1)(B), (c)(2)(B), and (d)(2)(B)]. The water quality protection standard (WQPS) [ §2550.2] is the basis of the Detection Monitoring Program. The WQPS is the site - specific process used to identify a release from the WMU. Evaluation monitoring (formerly called verification monitoring) must be implemented when- ever there is either statistically significant evidence of a release (determined during detection monitoring), or there is significant physical evidence of a release. The purpose of evaluation monitoring is to assess the nature and extent of the release from the WMU [ §2550.9(b)], to implement a monitoring program that will detect changes in the release [ §2550.7(b)(1)(C), (c)(2)(C), and (d)(2)(C), and §2550.9(e)], to propose and substantiate a revised WQPS for corrective action [ §2550.2 and §2550.4(a)(3) -(h)], and to develop a corrective action program to bring the WMU into compliance with the revised WQPS [ §2550.9(d)]. A corrective action program is implemented at the completion of the evaluation monitoring phase. The purpose of the corrective action program is to implement measures to clean up the release and bring the WMU back into compliance with the revised WQPS [ §2550.10(b- ),(c) and (e)], to implement source control measures [ §2550.10(c)], and to monitor the speed at which the corrective action measures will bring the WMU back into compliance with the WQPS [ §2550.7(b)(1)(D), (c)(2)(D), (d)(2)(D), and §2550.10(d),(e),(i),(j)] EBA's proposed strategy for the City of Ukiah Landfill is to develop a Water Quality Moni- toring Program (i.e., detection monitoring program) consistent with the requirements of revised Article 5. Once an approved Water Quality Monitoring Program is in place, and appropriate data have been collected and evaluated statistically, the site can then be evaluated with respect to the evaluation monitoring and corrective action requirements of revised Arti- cle 5. EBA will evaluate the existing Water Quality Monitoring Program developed for the landfill, and prepare an updated Water Quality Monitoring Program consistent with the requirements and performance standards of revised Article 5, §2550.0 through §2550.12. The following specific subtasks will be necessary to prepare the updated Water Quality Monitoring Pro- gram: Subtask 1 - Subtask 2 - L: \project\385 \Ukiah. agr Evaluate the Develop and on: Current Monitoring System Propose Water Quality Protection Standard Based o constituents of concern o concentration limits o point of compliance o monitoring points o compliance period Subtask 3 - Subtask 4 - Subtask 5 - Subtask 6 - Determine Background Values Evaluate and Propose Statistical Methods and Statistical Retest (Verification) Procedures Develop and Propose Sampling Frequency Develop and Propose Sampling and Analysis Methods /Procedures Subtask 7 - Prepare Proposed Monitoring and Response Program Each of these subtasks are described in detail below. Subtask 1 - Evaluation of Existing Water Quality Monitoring Systems EBA will evaluate the existing monitoring system with regard to compliance with revised Article 5. Particular emphasis will be placed on understanding site hydrogeology and using this information to evaluate whether the existing monitoring system (e.g. number, depth, and location of monitoring wells) will meet the performance standards of revised Article 5. In addition to requirements for groundwater monitoring, revised Article 5 specifies monitor- ing requirements for surface water and the unsaturated (vadose) zone. Although vadose zone monitoring is required by §2550.7(d) of revised Article 5, it is extremely difficult to install vadose zone monitoring devices after construction and placement of refuse. Installation of vadose zone monitoring devices would typically require the removal and rebuilding of the landfill. The RWQCB has the authority to eliminate all or part of the vadose zone monitor- ing requirements at existing landfills provided the discharger can demonstrate that the instal- lation of the system is not feasible and would require unreasonable moving (or dismantling) of the landfill. EBA will evaluate the feasibility of installing vadose zone monitoring systems, in accordance with revised Article 5 requirements, at the Ukiah Landfill. Subtask 2 - Develop and Propose Water Quality Protection Standard Under the requirements of revised Article 5, a water quality protection standard must be proposed for the landfill. This differs significantly from the repealed Article 5 where a water quality protection standard was assigned to each "indicator parameter" of a water quality monitoring program. This new water quality protection standard is based on the following five (5) components [ §2550.2]: o constituents of concern o concentration limits o point of compliance o monitoring points o compliance period Constituents of concern are defined as "the waste constituents, reaction products, and hazard- ous constituents that are reasonably expected to be in or derived from waste" ( §2550.3). A concentration limit is the "threshold" concentration of a constituent of concern that, when exceeded in a statistically significant manner, indicates possible leakage of the landfill. The water quality protection standard applies at the point of compliance, which is defined as the "vertical surface at the downgradient limit of the waste management area." Monitoring points include groundwater monitoring wells and surface water sampling locations at the point of compliance. The compliance period is defined as the active life of the facility and the closure period. However, the compliance period can be extended if a release is detected from a landfill site. EBA will identify constituents of concern for landfill on the basis of historical waste disposal data and monitoring data collected to date. A concentration limit will then be proposed for each constituent of concern, based on background values developed in Subtask 3. In accor- dance with revised Article 5, EBA will select a "short list" of monitoring parameters to be used for routine detection monitoring purposes. The "short list" is a subset of the constitu- ents of concern and is comprised of those chemicals whose characteristics are such that they will be effective indicators of leakage from the landfill. Use of the "short list" for routine monitoring purposes will reduce monitoring costs and the number of false positive readings (Type I error), while maintaining the performance standards of revised Article 5. Monitor- ing points will be proposed based on the evaluation performed in Subtask 1. The compliance period will be calculated based on the predicted closure and post - closure monitoring dates developed for the landfill. Subtask 3 - Determine Background Values Revised Article 5 requires the establishment of background values for each constituent of concern (which includes each monitoring parameter on the "short list "). Determination of a background concentration specific to each constituent of concern will be based on existing background monitoring data using statistical methods. However, if it is determined that the existing data are insufficient for determination of background, then EBA will propose a sampling and analysis program designed to collect sufficient data for the determination of background values. Background can be either a fixed numerical value or a statistical formula. The latter may be used in cases where an intra -well monitoring approach is used, or in cases where variables such as seasonality must be accounted for. Once background values have been established, EBA will propose specific concentration limits for the constituents of concern. Background values must be determined, and concentration limits specified, for each monitored medium (i.e., groundwater, surface water, and the unsaturated zone) applicable to the landfill. Subtask 4 - Evaluate and Propose Statistical Methods and Statistical Retest (Verification) Procedures Revised Article 5 places great emphasis on the use of statistical methods of data evaluation to determine whether "statistically significant evidence of a release" has occurred. All water L:\project\i85 \Uldah.agr quality monitoring programs must propose and substantiate one of the statistical methods of evaluation given in §2550.8(e)(8) for each constituent of concern (which includes each moni- toring parameter on the "short list ") such that the performance standards of §2550.7(e)(9) are met. The choice of statistical methods includes: o a parametric analysis of variance (ANOVA) o a nonparametric ANOVA o a tolerance or prediction interval procedure o a control chart o any other statistical method, proposed by the discharger, that meets the perfor- mance standards of Article 5, subject to approval by the RWQCB The above statistical methods are similar to those now required for landfills governed by the recently issued RCRA Subtitle D requirements (40 CFR 257 and 258). However, Article 5 contains an additional provision for statistical retests (verification procedures) [ §2550.7 (e)(8- )(E)] that, when used with the "short list" of monitoring parameters, provides a means of controlling potentially costly "false positive" readings (i.e., Type I error). EBA will propose and substantiate one of the designated statistical methods of analysis for each constituent of concern for each monitored medium. The establishment of background values in Subtask 3 will be necessary and will serve as the basis for the selection of appropriate statistical methods of analysis. EBA will also propose a statistical retest procedure that will meet the special performance standards of §2550.7 (e)(8)(E). Subtask 5 - Develop and Propose Sampling Frequency Revised Article 5 calls for a minimum sampling frequency of quarterly (one sample from each monitoring point) or semiannually (four samples from each monitoring point, twice per year), depending on the statistical methods selected to evaluate the monitoring data [§2550.7 - (e)(12)(A), (B)]. EBA will evaluate the sampling frequencies with respect to the proposed statistical methods, and will consider both cost and practicality when developing the proposed sampling frequency for the detection monitoring programs. Subtask 6 - Propose Sampling and Analysis Methods /Procedures The sampling and analysis procedures proposed by EBA will serve as the basis for obtaining representative samples from each monitored medium, and for obtaining accurate and reproducible data. Specific sampling methodologies, field and laboratory analytical methods, and Quality Assurance /Quality Control (QA /QC) procedures will be consistent with the following guidance documents: o Procedures Manual for Groundwater Monitoring at Solid Waste Disposal Facilities, U.S. Environmental Protection Agency (EPA), EPA - 530 /SW -611, August 1977 o Test Methods for Evaluating Solid Waste: Physical /chemical Methods, EPA, EPA L:\project\385 \Udah.agr SW -846, Third Edition, November 1986 o Methods for Organic Chemical Analysis of Municipal and Industrial Wastewater, EPA, EPA - 600/4- 82/057, July, 1982 o RCRA Groundwater Monitoring Technical Enforcement Guidance Document, OSWER 9950.1, September 1986 Subtask 7 - Prepare Proposed Monitoring and Response Programs Subtask 1 through Subtask 6 above will serve as the basis for the preparation of a comprehensive and site - specific Water Quality Monitoring Program, consistent with the requirements of revised Article 5. EBA will prepare a draft and final Proposed Water Quality Monitoring Program for submittal to the City of Ukiah. The reports will include all maps, profiles, equations, tables, etc., that are necessary to help clarify the work. I.B - DEVELOP FINANCIAL ASSURANCE COST ESTIMATES New financial assurance regulations promulgated in revised Article 5 mandate the establishment of a financial assurance mechanism sufficient to fund the clean-up of "all known or reasonably foreseeable releases" from the Waste Management Units at the site. The amount of the financial assurance mechanism is subjectively based on the dependability of the landfill containment systems, and the reliability of the detection monitoring system. Evaluating the potential for environmental impairment and developing a realistic cost projection must be based on site - specific data, including containment systems and operational procedures at the landfill site, geologic and hydrogeologic features, the amount and types of wastes received at the site, estimates of the volume of leachate and landfill gas generation, and the Water Quality Monitoring Program developed for the site. For the City of Ukiah Landfill, EBA will review and evaluate the pertinent site - specific information and develop a realistic cost projection for clean-up efforts of a reasonably foreseeable release of waste constituents from landfill site. Data to be evaluated includes (1) estimates of leachate generation volumes, (2) estimates of the nature and extent of a release, and the physical and chemical mechanisms likely controlling the transport of waste constituents, and (3) estimates of the volume of groundwater that could be potentially impacted and that could require treatment. EBA will prepare draft and final Financial Assurance Cost Estimates for the landfill. The cost estimates will include all maps, tables, and any plans or details generated as part of Subtask I.B Financial Assurances Mechanisms Article 3.5 of Title 14 includes financial mechanism forms and regulations that may be used to satisfy Article 5 of Chapter 15. Applicable mechanisms may include Letter of Credit, Pledge of Revenue (for only public agencies), Financial Means Test (for private companies), and, possibly, an enterprise fund which accumulates over a relatively short period of time. L:\project\385 \Uloah.agr Under Title 14, Pledge of Revenue and Financial Means Test are accepted only for postclosure maintenance. However, these two mechanisms may warrant serious consideration for Article 5 of Chapter 15 because they are relatively inexpensive to implement. Periodic updates for inflation and review of the financial means test and revenue source for a pledge of revenue would be essential should they be accepted. Accumulation of funds over a long period of time (e.g. an enterprise fund) would not be appropriate because corrective actions may have to be performed at any time during the active, closure, and postclosure periods. Other mechanisms such as surety bonds, government securities, and certificates of deposit are complex, expensive, and seldom used. TASK II - CHARACTERIZE GROUNDWATER CONTAMINATION IL - PREPARE WORK PLAN Prior to beginning field activities, we anticipate that it will be necessary to submit a detailed a work plan to the North Coast Regional Water Quality Control Board (RWQCB) for review and approval. This work plan would present an investigative strategy designed to address issues of concern regarding water quality at the landfill site, as expressed in the letter from David Evans (RWQCB) dated October 5, 1992. We understand that there are three areas of concern regarding the water quality at this site: (1) the contaminants detected in groundwater monitoring wells 90 -4, 90 -5, and 87 -1; (2) the background water quality at the site; and (3) the water quality in the vicinity of the leachate containment pond. In general, the work plan shall adequately summarize previous environmental and hydrogeologic data generated at this site, identify the purpose of additional investigation, and propose a method of exploration capable of achieving the desired results (a brief discussion of the methodology is provided below). The work plan will also describe the proposed drilling methods, our rationale for the placement of additional monitoring wells, well construction and development details, quality control and quality assurance (QA /QC) measures, and the project time schedule. II.B - PLUME CHARACTERIZATION One of the primary purposes of this investigation is to determine the extent of contaminants discovered in the vicinity of monitoring wells 90 -4 and 90 -5, which are located near the northerly edge of the landfill, and in the vicinity of monitoring well 87 -1, which is located near the westerly property boundary. Based on recent discussions with Dave Evans, we anticipate that it will be necessary to install two additional wells just north of monitoring wells 90 -4 and 90 -5 to determine the extent of contaminant migration in this area. We anticipate that these wells will be extended to a total depth of approximately 50 feet, in order to ensure penetration of the saturated zone throughout the year. It should be noted, however, that the total depth of the wells may vary, depending on the elevation of the drilling sites and local hydrogeology. The wells will be designed in accordance with specifications outlined in Bulletin 74 -90, Monitoring Well Standards: State of California, prepared by the State Department of Water Resources in cooperation with the State Water Resources Control Board. They will be constructed of clean, two inch diameter, flush - threaded PVC casing, and secured within locking above - ground monuments. Approximately ten to fifteen feet of perforated well screen will be installed from just above the highest seasonal groundwater level to the bottom of the well, and surrounded by a filter pack of washed Monterey sand. To ensure that the well casing is properly centered in the boreholes, it will be installed within the string of hollow -stem augers, or by using stainless steel centralizers, depending on the drilling method. The annular materials (filter pack, bentonite, etc.) will be placed within the hollow -stem as the augers are withdrawn, or through a tremie pipe. The monitoring wells will be developed by gently surging the wellbore with a teflon surge block, followed by continued purging using a bailer, a Brainard -Kilman 1.7 inch hand pump, and /or a GEOGARD air -lift pump driven by L: \projux\385 \Uidah. agr an oil -less compressor. At regular intervals (approximately after each well volume of water is removed) the pH, conductivity, temperature and clarity of the water will be tested to verify the effectiveness of the development process. We understand that contaminants have been detected in monitoring well 87 -1, which has been completed in the Quaternary alluvium. However, leachate contaminants were not detected in a nearby well (90 -2) that penetrates water bearing zones in the underlying continental deposits. Accordingly, we believe that wells 87 -1 and 90 -2 may be hydraulically independent, and that if leachate impacted groundwater is present in this area, it may limited to the younger alluvial deposits. It should be noted, however, that leachate contaminants were not detected in monitoring well 90 -1, which was also completed in the Quaternary alluvium further down - gradient of 87 -1. Based on these results, it is our understanding that the RWQCB would like further clarification of the distribution contaminants in the Quaternary alluvium. To assess the extent of contaminant migration in this area, we recommend that groundwater samples be collected using temporary well points, or a HydroPunch', as opposed to the installation of permanent wells. The boreholes for the well points would be advanced with steam - cleaned, hollow -stem augers to a depth of approximately 3 to 5 feet above the first water - bearing layer. We anticipate that the depth to this layer will be on the order of 15 to 20 feet below grade in the Quaternary alluvium. Therefore, we anticipate that the total depth of each HydroPunch'''°` borehole will be approximately 10 to 15 feet below the surface. The HydroPunch"` sampling tip would then be driven through the center of the augers, down to the saturated zone. Groundwater samples would be collected from the test boring and sent the laboratory for testing. It should be noted that to drill in these areas some grading will be necessary to provide access roads and drilling pads. We understand that access roads and drilling pads will be provided by the City of Ukiah. II.0 - BACKGROUND WATER QUALITY AND GRADIENT EVALUATION The purpose of Subtask II.0 is to provide additional data regarding the background water quality in the area of the landfill. The primary reasons for establishing the background water quality in this area to provide baseline water quality parameters which can be used to assess the impact of the landfill on groundwater in other areas at the site, and to assess the hydrogeologic relationship between the refuse site and adjacent sites (such as the Vichy Springs Resort). To address these concerns, we propose to install one groundwater monitoring well directly between the landfill site and Vichy Springs. We anticipate that the total depth of a monitoring well in this area will be approximately 100 feet. Again, the final depth of this well will depend on the elevation of the drilling site and the hydrogeology. The well would be constructed of clean, two inch diameter, flush - threaded PVC casing, and secured within locking above - ground monuments, as discussed above. II.D - LEACHATE POND EVALUATION We understand that the RWQCB has requested that a groundwater monitoring well be established near the northeast corner of the leachate containment pond to assess the possible impact of the pond on water quality in this area. We anticipate that the monitoring well will extend to a total depth of between 35 and 50 feet, based on data from nearby wells. However, the total depth of the well may vary, depending on the elevation of the drilling area and the hydrogeologic conditions encountered in the vicinity of the leachate containment pond. As discussed above, the well would be designed in accordance with specifications outlined in Bulletin 74 -90, Monitoring Well Standards: State of California, and constructed of clean, two inch diameter, flush - threaded PVC casing. The monitoring well will be developed by gently surging the wellbore followed by continued purged of the well using a bailer, a Brainard -Kilman 1.7 inch hand pump, and /or a GEOGARD air -lift pump driven by an oil -less compressor as discussed above. II.F - LEACHATE MOUNDING EVALUATION An investigation of conditions within the landfill is required by the RWQCB to identify areas of possible leachate accumulation (leachate mounding) and potential migration processes which could be acting as the source of contaminants found in groundwater down gradient of the landfill. A field seismic refraction survey will be conducted at the site to analyze general landfill subsurface conditions including: o Thickness of refuse and cover soil o Zones of saturation within the refuse o Depth to landfill subgrade and subsurface variability o Potential leachate mounding areas Seismic Refraction Seismic refraction methods consist of measuring travel times of compressional waves through the subsurface. Seismic wave energy is transmitted into the ground where it is refracted along velocity interfaces and then back to the ground surface. By measuring the travel time of seismic waves from source (shotpoint) to detectors at known distances on the surface, the seismic velocities and thickness of the respective velocity layers can be determined. The geophysical field crew will be headed by an experienced registered geophysicist. Seismic data will be recorded on a Geometrics ES- 1200F, 12- channel engineering seismograph and 10 -Hertz geophones. This system has enhanced seismic data capabilities as well as filtering. The seismic survey will consist of five profiles across the landfill. Each profile will consist of 2 - 3 seismic spreads approximately 300 feet long. Each spread is a collinear array of 12 geophones spaced 25 to 50 feet apart. Shot points will be located approximately 25 feet beyond the first geophone at each end of the spread. It is anticipated that a total of approximately 3,480 feet of seismic refraction line in 12 seismic spreads will provide the minimum necessary coverage required to adequately characterize the subsurface conditions at the landfill. A Geophysical Survey Report will be submitted at the conclusion of the work which describes the methodology for both data acquisition and data analyses, discusses the results, and provides our interpretation regarding the general subsurface landfill conditions. Electrical Resistivity (Optionall Depending on the results of the seismic refraction survey, an optional electrical resistivity survey could be conducted at specific locations on the landfill to further characterize zones of saturation within the refuse and areas of potential leachate accumulation. An optional cost is included in the cost proposal should the city choose to the perform the electrical resistivity survey. Electrical resistivity methods consist of electrical measurements taken at the ground surface. Typically, a co -liner array of four electrodes are placed in the ground at specific separations. Electrical current is input to the ground through two of the electrodes in the array. The voltage drop produced be the resulting electrical field is measured across the remaining electrodes. The voltage drop is dependent on the electrical properties of the subsurface. Variations in subsurface resistivity can provide information regarding extent of saturated zones within the refuse, depth to leachate, and relative leachate quality. L:\project\385\Ukizh.agr TASK III - REVISE REPORT OF WASTE DISCHARGE (RWD) A RWD was prepared for the City of Ukiah Solid Waste Disposal Site by EBA and submitted to the Regional Water Quality Control Board (RWQCB) in May 1991. This report was prepared in conjunction with a Facility Permit revision for the landfill and for issuance of revised Waste Discharge Requirements in compliance with Title 23, CCR, Division 3, Chapter 15. Comments on the May 1991 RWD, dated October 5, 1992 have been received from the RWQCB. Additionally, groundwater monitoring regulations for landfill disposal have been revised in the recently adopted revised Article 5 of Chapter 15. In order to comply the RWQCB review comments and meet current regulations the RWD will require the following revisions and additions: • Include a comprehensive water quality monitoring program that meets new environmental monitoring performance standards in accordance with revised Article 5 of Chapter 15. The scope of work for this program was discussed in Task I above. This monitoring program along with the required financial assurance cost estimates for corrective action will be prepared as a stand alone document as described and included into the RWD as an appendix. • The site capacity /waste volume calculations will need to be revised to reflect the current and projected conditions for waste volumes, waste reduction measures and diversion rates. Calculations should be done both for current waste rates with anticipated population increases and waste diversion and for a scenario using the average waste volumes specified in the proposed permit application. • In various sections in the current RWD reference is made to a possible landfill expansion to the north canyon area. It is our understanding that this is not an option that the City wants to include or discuss in the RWD at this time and reference to it should be taken out. • A household hazardous waste plan will need to be included in the RWD that at minimum consists of a load checking program, a program to provide residents with means for disposing of household hazardous waste, hazardous material storage facilities and disposal alternatives for hazardous waste. It is our understanding that these programs have already been implemented by the City and will need to be described in detail in the RWD. • A closure and postclosure maintenance plan in accordance with the provisions of Article 8 and Article 9, Sections 2597 of Chapter 15 shall be included. The final closure drawing will need to be revised to include filling in an area along the southerly boundary as previously discussed. The following additional descriptions and discussions will also need to be included: Projected schedule for partial and final closure. Description of proposed final treatment procedures. Final closure configuration. L:\project\385 \Uldah.agr Description of all postclosure waste containment features. Description of precipitation and drainage control features. Description of leachate control features and procedures. Map and discussion of groundwater and unsaturated zone monitoring. Evaluation of anticipated settlement. Description and nature of the final cover. Postclosure land use. Cost estimates anticipated for closure and postclosure. Many of these items are already discussed elsewhere in the RWD, however, some will require additional discussion, such as an evaluation of anticipated settlement, description of the final cover system and cost estimates for closure and postclosure maintenance. All available information from the groundwater contamination evaluation described in Task II, depending upon scheduling, will be incorporated into the appropriate sections of the RWD. Copies of the revised RWD will be provided as follows: • 2 Draft copies for City review. • 5 Final copies revised per City comments for City use and submittal to the RWQCB. L: \project 385 \Uliah.agr TASK IV - REVISE REPORT OF DISPOSAL SITE INFORMATION (RDSI) The RDSI and Engineer's Report prepared by EBA and submitted to the California Integrated Waste Management Board (CIWMB) will also require revisions to support the City's application for revision of the Solid Waste Facility Permit. The 1991 RDSI was prepared in accordance with Title 14, Sections 17601 - 17751 and Section 18222, and EBA would propose to utilize the same format when updating the report. However, the CIWMB has developed a new standard format for RDSI's as outlined in CIWMB Permit Desk Manual, dated June 1992. The format is different from previous accepted formats and would require substantial changes to conform. Although the information required is basically the same, much more discussion and analysis is expected. We have not been able to determine if the CIWMB would require conformance to their new format, so for the purpose of this proposal we have assumed the format of the current RDSI will be acceptable. An optional cost is included in the cost proposal for conformance to the Permit Desk Manual (June 1992) should that be required. Revisions to the RDSI will be similar to those discussed in Task 3, as applicable. In addition all review comments from the LEA made in letter dated March 9, 1992 will also be Incorporated. EBA will coordinate with the City and the LEA throughout the RDSI process. Copies of the revised RDSI and Engineer's Report will be provided as follows: • 2 Draft copies for City review. • 5 Final Draft copies revised per City comments for LEA review. • 5 Final copies revised per the LEA's comments for submittal to the CIWMB. TASK V - GENERAL INDUSTRIAL ACTIVITY STORM WATER PERMIT A large number of facilities recently defined by the U.S. Environmental Protection Agency regulations under 40 CFR Section 12226(b)(14) as having storm water discharges must obtain coverage under an NPDES permit. The State Water Resources Control Board adopted a General Industrial Storm Water Permit for facilities seeking coverage. The General Permit, fact sheet, and application forms are included in a document package prepared by the State Water Board and dated 18 December 1991. Modifications to the monitoring program and reporting requirements were proposed dated August 17, 1992. Among the facilities covered, municipal solid waste landfills and transfer stations are generally included except: (a) Facilities in Santa Clara County which drain to San Francisco Bay must seek coverage under a separate General Permit issued by the San Francisco Bay Regional Board; (b) Facilities with an existing NPDES individual permit are required to have an individual NPDES permit; and (c) Facilities on Indian Lands. Furthermore, facilities that discharge all storm water to municipal sanitary sewer systems or facilities which capture and contain all storm water are not required to obtain a permit. Under the new Storm Water Discharge requirements virtually all solid waste handling and disposal facilities need to obtain a Permit. Since the State of California has opted to issue a single statewide general discharge permit we propose the following to comply with the regulations: Task V.A - Notice of Intent The submittal of a Notice of Intent (NOT) letter to the State to request to be included under the statewide permit. No fee is required of landfills where fees are currently paid to the RWQCB for annual monitoring. For purposes of this proposal the NOI if not already submitted by the City will be submitted by EBA on behalf of the City. Submittal of the NOI may be on forms prepared by the State. The key issues on the application include: • Operator identification • Facility information • Receiving water information • Site map • Certification by the owner /operator Task V.B - Storm Water Pollution Prevention Plan The preparation of a Storm Water Pollution Prevention Plan (SWPPP). Key items to be included are: • Certification by owner /operator • Introduction /Location Map /Site Map • Narrative description of the facility • List of Reasonable Potential Pollutants • Size of facility /Impervious areas • Significant spills or leaks to storm water since November 19, 1988 • Summary of existing storm water sampling data • Storm water management controls • Preventative maintenance and good housekeeping • Spill prevention and response • Storm water management practices • Sediment and erosion practices • Non -storm water discharges • Employee training • Inspection Prior to preparation of the SWPPP a site visit will be made to verify field conditions and to identify issues which should be addressed in the SWPPP. Particular attention will be paid to access, tipping areas, peripheral drainage, onsite surface drainage and sedimentation controls, area indicating erosion potential, cover material stockpiles and likely discharge points for onsite drainage. Notice will also be made of current pollution prevention activities. A draft SWPPP will be prepared for the site for review by the City. The draft plan will identify specific activities which, implemented, would assist in attainment of the objectives of the regulations and the elimination of preventable contamination due to the use of the site for landfill purposes. Where appropriate, text describing the recommended activities will be supplemented by maps or engineering drawings to further define the recommendations. After review by the City, revisions will be addressed and a Final Plan submitted for the City to place on file. The Storm Water Pollution Prevention Plan is to be retained onsite and made available to representatives of the Regional Board upon request. It is a public document and should also be on file in the main office. The North Coast Regional Board has also requested that the SWPPP be submitted to their Santa Rosa office. Task V.0 - Storm Water Monitoring Program The preparation of a Storm Water Monitoring Program and its implementation by January 1, 1993. The monitoring plan should include: • Rationale for selection of the monitoring methods • Analytical test methods to be employed L: \project\385 \Uldah.agr • Description of the sampling methods, sample locations and frequency of monitoring • QA /QC program • Description of the procedures to evaluate the effectiveness of the program • A list of chemicals or pollutants to be sampled for The first monitoring report is due July 1, 1993, and is to be submitted to the Executive Officer of the Regional Board. The monitoring program shall document the elimination or reduction of specific pollutants, resulting from the implementation of the SWPPP outlined in Task VB. Under the August 17, 1992 revisions exemptions from sampling and analysis are allowed. To obtain an exemption the discharger must either self - certify that areas of industrial activity are not exposed to storm water or the local agency which has jurisdiction over the water course which receives storm water discharge must certify that the discharger has developed and implemented an effective SWPPP and should not be required to collect and analyze storm water samples for pollutants. Prior to preparation of a monitoring program, EBA will investigate the possibility of obtaining an exemption by either self - certification or local agency certification. If an exemption can be granted the monitoring program will not be necessary. As an additional task EBA can either train City personnel who are most likely going to be the parties responsible for sampling in the proper techniques of sampling or arrange to provide the sampling and analysis. We can evaluate the test results, compile the necessary reports and submit them to the RWQCB. Based upon the test results, EBA will identify any issues of possible concern and provide recommendation to the City. L:\proje t\385Wldah.agr ESTIMATED COSTS The following Table presents EBA Wastechnologies' cost estimate for performing the tasks described in this proposal. These costs reflect EBA's best judgment, but may vary depending on subsurface conditions, speed of drilling, and ease of access. EBA will not exceed the cost estimate without written authorization from the City of Ukiah. Actual costs will be billed on a time - and - expense basis in accordance with the Standard Schedule of Fees and Rates attached. We have made the following cost saving assumptions in developing the cost estimate: • The City of Ukiah will provide access to drilling sites. • Surveying of the monitoring well -head elevations will be conducted by City of Ukiah personnel. These cost estimates also assume that drill cuttings and water generated from monitoring well installation and sampling events is not hazardous, and can be discharged at the disposal site. Wastes that are determined to be hazardous must be disposed of properly. All transportation and waste disposal, if it is necessary, must be arranged and obtained by the City of Ukiah and manifested by the City of Ukiah; however, EBA will be available to assist in coordinating these activities. EBA will not assume any liability as an arranger or generator for hazardous waste disposal purposes. These cost estimates do not include removal and disposal of Hazardous: • drill cuttings • monitoring well development water • sampling purge water TABLE 1 UKIAH LANDFILL ADDITIONAL ENGINEERING SERVICES COST ESTIMATE TASK EBA DIRECT LABOR HALLEN- BECK COSTS OUTSIDE SERVICES MISC.
