Director of Public Works City of Ukiah (City) 300 Seminary Avenue Ukiah, CA 95482-5400 RE: PROPOSAL FOR PAST AND FUTURE FINAL CLOSURE PROFESSIONAL ENGINEERING SERVICES CITY OF UKIAH LANDFILL MENDOCINO COUNTY, CALIFORNIA Dear Mr. Eriksen: EBA Engineering (EBA) has prepared this Proposal to address past and future professional engineering services associated with final closure of the City of Ukiah Landfill (Landfill). As you are aware, closure of the Landfill has been in a state of transition for an extended period of time. The transition has been the result of several changes in the final cover design as a means of reducing overall construction costs, coupled most recently with the regulatory agencies' decision to require a minimum foundation layer thickness of two feet as opposed to the previously approved one foot thickness. At this point in time, it appears that the City and the regulatory agencies have come to a mutual understanding on the final cover design, thereby providing a definitive pathway for moving forward with the project. Due to the proposed transition to the ClosureTurfTM final cover design in the fall of 2015, most of EBA services since that transition has been related to updating construction and permitting documents (i.e., design technical specifications and drawings, revised Design Plans for landfill gas [LFG] collection and control system, revised Final Closure and Postclosure Maintenance Plans [FCPMPs], etc.) to reflect the new design, as well as technical support services for the City's dealings with regulatory agencies on matters related to the thickness of the ClosureTurfTM's geomembrane component and the foundation layer, storm water discharge modifications, and California Environmental Quality Act (CEQA) issues. Many of these tasks were time sensitive to maintain compliance with the Landfill's Notice and Order. Further complicating the project was the City's decision to proceed with the preparation of an Environmental Impact Report (EIR) in defense of a potential law suit by Vichy Springs. In light of the fluid nature of 825 Sonoma Avenue, Suite C • Santa Rosa, California 95404 (707)544-0784 • FAX (707)544-0866 • www.ebagroup.com these developments, EBA has not until now had a well-defined work scope to generate a reliable cost proposal to complete the final closure design services. Based on this circumstance and with the exception of a partial billing on December 31, 2015 (i.e., billed remaining portion of budget from May 13, 2015 Amendment #5), EBA has not invoiced the City for services rendered since July 25, 2015. Thus, as part of this Proposal, EBA is seeking reimbursement for services rendered since July 25, 2015, as well as for future design, agency permitting, interim project management (due to postponement of construction until 2021), and bid assistance services from this point forward. In regards to services already rendered, EBA has reviewed the work performed and compared it to prior tasks of a similar nature to ensure that there was no duplication of effort. For example, there have been several changes in design since 2002 that have entailed the preparation of construction drawings, technical specifications, construction quality assurance (CQA) plans, and engineer's estimates. These changes, which were implemented to either reduce construction costs or requested by the regulatory agencies, have included transitioning from a compacted clay liner to a geosynthetic clay liner (GCL) final cover system, incorporation of drainage and gas relief layers into the GCL final cover design, and most recently the transition to the ClosureTurfTM final cover system. In this regard, only those services associated with the ClosureTurfTM transition are being considered for reimbursement. Table 1 (attached) provides a summary of the services that have not been invoiced to date. The costs are itemized according to the specific tasks for which the services were performed. The following provides a breakdown of the various services and milestones completed over the period in question: • Prepared Addendum #2 to the Joint Technical Document (JTD), including revising the FCPMP to present the transition to the ClosureTurfTM final cover system (August 2015). • Prepared Authority to Construct (ATC) Permit application for submittal to the Mendocino County Air Quality Management District (MCAQMD) (September 2015). • Prepared revised ATC Permit application at MCAQMD's request to use an alternate application form and to update the LFG Design Plan to account for the transition to the ClosureTurfTM final cover system (October 2015). • Prepared Initial Study and Mitigated Negative Declaration (November 2015). • Prepared revised Mitigated Negative Declaration to incorporate City comments (January 2016). • Prepared revised FCPMP at the request of CalRecycle to incorporate the changes presented in JTD Addendum #2 into a single document (March 2016). Final Closure Design Proposal 11.13.19 2 EBA ENGINEERING • Prepared and submitted the required 401, 404, and 1602 permits (March 2016). • Prepared response to regulatory comments to March 2016 FCPMP. In addition, revised the FCPMP to incorporate the regulatory comments as requested by CalRecycle (May 2016). • Prepared response to comments to May 2016 FCPMP (May 2017). • Prepared isopach map of soil cover thickness as requested by CalRecycle (July 2017). • Coordinated survey of power lines extending over the Landfill with Pacific Gas and Electric Company (September 2017 through April 2018). • Attended meeting with City at the California Regional Water Quality Control Board (RWQCB) to negotiate liner and foundation layer thicknesses (October 2018). • Prepared Naturally Occurring Asbestos Geologic Evaluation Report as requested by the MCAQMD (January 2019). • Prepared revised FCPMP, including technical specifications, design plans, CQA Plan, updated LFG Design Plan, and engineers cost estimate to account for design changes resulting from 2 -foot foundation layer requirement (April 2019). • Provided technical support during preparation of the draft EIR as requested by the EIR consultant (July through September. 2019). • Coordinated resubmittal of 401, 404, and 1602 permits, as well as preparation of Incidental Take Permit for change in classification of foothill yellow -legged frogs (April 2019 to Present). • Provided various project management duties throughout the period in question that included attendance at meetings, participating in conference calls. responding to regulatory inquiries. and consultation and other services requested by the City. In regards to future services. there are several primary tasks that require completion prior to commencement of the construction project. These tasks include: redesigning the final grades (landfill and borrow area) to compensate for changes in existing grades as determined by new surveys performed by Munselle Civil Engineering and Land Surveying following the April 2019 submittal; wrapping up final punch list items associated with the construction drawings, technical specifications and CQA plan; completion of the 401, 404. 1602. and Incidental Take Permit resubmittals; interim project management through December 2020; and bid assistance. The cost for these services are summarized in Table 2 (attached).
