EBA has performed portions of these services for the City since 2002 under a variety of contract amendments and work authorizations. These services include the monitoring and reporting requirements outlined in the current Waste Discharge Requirements (WDR) Order No. R1-2002-0061, landfill gas (LFG) monitoring and reporting as required by Title 27 of the California Code of Regulations (27CCR) Section 20921, additional LFG monitoring and reporting as required by the Fifth Amendment of Notice and Order 2013-01 issued by the Mendocino County Public Health Department – Department of Environmental Health (i.e., Local Enforcement Agency [LEA]), and surface emissions monitoring and reporting as required by the current Landfill Methane Regulation (LMR) as described in Title 17 of the California Code of Regulations (17CCR) Section 95460. The current WDR and the current LMR are subject to anticipated revisions by the regulatory agencies during the contract period (fiscal year 2026-2027). These revisions will result in a change to the scope of work described herein. The timing and nature of the revisions to the WDR and the LMR are not fully understood at this point. For cost estimation purposes, this cost estimate proposal assumes continuation of the current monitoring and reporting program and all work will be billed on a time and materials basis. While the timing and nature of future revisions to the WDR and LMR are yet to be determined, the following estimated costs are considered a conservative estimate of the future level of effort based on recent discussions with the regulatory agencies and the information that is currently available. That being said, additional costs could be required due to the uncertainty of proposed changes to regulatory requirements. EXPLANATION OF PROPOSAL REVISION It should be noted that a cost estimate proposal was previously submitted on April 30,2026. As discussed in email correspondence dated June 2, 2026 and a subsequent telephone conversation with the City on June 3, 2026, EBA mobilized to the Landfill on June 2, 2026 to perform the Second Quarter 2026 Surface Emissions Monitoring (SEM) under Professional Service Agreement 2526-164. However, multiple wild hogs were observed roaming through the high grass which made for unsafe conditions for our field staff. As such, the SEM event was ATTACHMENT A postponed. The SEM involves 2-3 days of walking the surface of the Landfill at distances far from the safety of a vehicle to retreat to. As such, an unexpected wild hog encounter would be potentially dangerous. The steep slopes and other safety concerns noted in the last Alternative Compliance Option (ACO) submitted to the applicable regulatory agencies are compounded by the presence of the wild hogs. Based on these conditions, EBA requested partial mowing of the Landfill. Being able to see the hogs approaching would decrease the associated risk and allow for more time to respond. Mowing efforts are currently underway. EBA appreciates the City’s efforts to address this issue. Additionally, EBA plans to make the following changes to the field work process going forward to address the health and safety issues posed by the wild hogs: 1.) Equipping our field staff with wildlife deterrent spray (bear spray) and providing appropriate training for its use. 2.) Implementing a “buddy system” for field work at the Landfill which occurs at a far enough distance from a vehicle where safe retreat is not an option. Going forward, the completion of SEM will require two field technicians. Implementation of the buddy system will not have an effect on other landfill monitoring activities since they either occur at close proximity to a vehicle and/or already have two field technicians assigned due to the nature of the scope of work. Due to the increased labor associated with implementing the buddy system to address the health and safety issues at the Landfill posed by the presence of wild hogs, the April 30, 2026 proposal is revised herein. The associated increased costs are $4,590.00 per quarter, or $18,360 per year. If the additional labor costs to have a second EBA field technician present for SEM is cost prohibitive, alternate options previously discussed with the City include: a.) quarterly SEM and associated verification testing to be performed by City personnel (training would be provided by EBA) or b.) submitting a new ACO to the regulatory agencies proposing the use of drone equipment for SEM. A copy of the previously provided January 14, 2026 quote from Sniffer Robotics for drone SEM is also attached to this Proposal for your consideration. Lastly, EBA understands that the City is currently applying for a depredation permit with the California Department of Fish and Wildlife to allow for mitigation of the wild hogs which will be especially important during and following the upcoming closure of the Landfill. If hog removal becomes viable and the wild hogs are mitigated, then the additional costs for SEM would not be necessary since the scope of work would no longer require employing the buddy system that is currently required by the wild hog situation. As discussed in more detail herein, all work would be performed on a time-and-materials basis not to exceed the estimated costs. SCOPE OF WORK Task 1: Project Management and Project Coordination Task 1 includes project management and project coordination associated with implementing the environmental compliance monitoring and reporting services described as Tasks 2 through 8 below. For cost estimation purposes it is assumed that approximately 1.5 hours will be required per week. Task 2: Environmental Sampling Events Task 2 includes the performance of environmental sampling events for groundwater, surface water, and leachate as required by the current WDR (Order No,. R1-2002-0061). These events during the contract period will include: the Third Quarter 2026 sampling event (Task 2a), the Fourth Quarter 2026 sampling event (Task 2b), the First Quarter 2027 sampling event (Task 2c), the Second Quarter 2027 sampling event (Task 2d), and as-needed verification testing (Task 2e). Assumptions: Since the anticipated timeframe and scope of future revisions to the WDR and associated Monitoring and Reporting Program (M&RP) are unknown at this time, the estimated costs for Task 2 are based on the current WDR and M&RP. Analytical testing costs are not included since it is assumed that all analytical testing services will be performed by the City’s contract laboratory (K Prime, Inc.). Additionally, it is assumed that the City will continue to perform routine inspections for the standard observations required by the current WDR. Task 2e (As-Needed Verification Testing) assumes that one verification sampling event will apply during the contract period. However, the need for verification testing is contingent on the future analytical results, so it is possible that additional verification events may be required which would have additional costs. Task 3: Detection Monitoring Reports Task 3 includes the preparation of quarterly detection monitoring reports documenting groundwater, surface water and leachate sampling results as required by the current WDR (Order No. R1-2002-0061). Detection monitoring reports will be prepared for Third Quarter 2026 (Task 3a), Fourth Quarter 2026 (Task 3b), First Quarter 2027 (Task 3c), and Second Quarter 2027 (Task 3d) for submittal to the North Coast Regional Water Quality Control Board (NCRWQCB). Assumptions: Similar to Task 2, the estimated costs for Task 3 are based on the current WDR and M&RP. Additional costs may apply if the WDR and M&RP are revised during the contract period. Task 4: Quarterly Landfill Gas Monitoring and Reporting Task 4 includes the performance of quarterly perimeter LFG monitoring and preparation of quarterly reports as required by 27CCR Section 20921. Monitoring and reporting during the contract period includes Third Quarter 2026 (Task 4a), Fourth Quarter 2026 (Task 4b), First Quarter 2027 (Task 4c), and Second Quarter 2027 (Task 4d). Reports will be submitted to the LEA and the California Department of Resources Recycling and Recovery (CalRecycle). Assumptions: Task 4 does not include monthly LFG monitoring and reporting which is required by the LEA as part of the closure construction process. Monthly LFG monitoring is described below as Task 8. Task 5: State GeoTracker Update Task 5 includes the preparation and upload of applicable electronic data format (EDF) files to the State Water Resources Control Board’s GeoTracker internet database for data generated during the contract period (i.e., Third Quarter 2026 [Task 5a], Fourth Quarter 2026 [Task 5b], First Quarter 2027 [Task 5c], and Second Quarter 2027 [Task 5d]). Task 6: Surface Emissions Monitoring Task 6 includes the performance of surface emissions monitoring during the contract period as required by the current LMR. Surface emissions monitoring during the contract period includes Third Quarter 2026 (Task 6a), Fourth Quarter 2026 (Task 6b), First Quarter 2027 (Task 6c), and Second Quarter 2027 (Task 6d). The need for verification testing, which is required 10 days following a documented methane surface exceedance and the subsequent implementation of mitigation measures by the City, is currently unknown since it is contingent on the future monitoring results. The estimated cost for verification testing (Task 6e) assumes that one verification testing event will be required per quarter (a total of four verification re-testing events are included). Assumptions: The scope of work is based on the current LMR. Additional costs may apply based on the timing for adoption of the revised LMR, as well as whether an Alternative Compliance Option (ACO) is approved. The use of drone monitoring equipment may be required which would involve additional costs. Task 7: Surface Emissions Reporting Task 7 includes the preparation of the annual Heat Input Capacity Report (Task 7b) and the Annual Report (Task 7c) documenting surface emissions monitoring for submittal to the California Air Resources Board (CARB) and the Mendocino County Air Quality Management District (MCAQMD). Task 7a includes regulatory coordination, meetings, and research related to the proposed revision to the LMR. It should be noted that Task 7 does not include preparation of quarterly reports for surface emissions which are not required by the current regulations but have been prepared during the last year as a means of documenting the City’s efforts to regain compliance with the LMR regulations. The quarterly reports were removed as a cost savings measure as they are technically not required at this point. Task 8: Monthly Landfill Gas Monitoring and Reporting Task 8 includes the performance of monthly LFG monitoring and reporting as required by the LEA (Notice and Order 2013-01). The costs for quarterly LFG monitoring in July 2026, October 2026, January 2027, and April 2027, as required by CCR27, are already included under Tasks 4a, 4b, 4c, and 4d. As such, Task 8 includes the monthly LFG monitoring and reporting for the remaining eight months of the contract period (Tasks 8a through 8h). COST ESTIMATE SUMMARY Per the City’s request, these services will be performed on a time-and-materials basis not to exceed the following amounts without prior approval by the City.
