Approve fees for Ninyo & Moore for Environmental Remediation-9255 Imperial Hwy• r• OFFICE OF AO MOHAMMAD MOSTAHKAMI,• OF i DATE: MARCH 13, 2018 SUBJECT: ENVIRONMENTAL REMEDIATION SERVICES AT 9255 IMPERIAL HIGHWAY, CAPITAL IMPROVEMENT PROJECT NO. 17-01 — APPROVE ADDITIONAL FEES FOR ENVIRONMENTAL REMEDIATION That the City Council approve fees in the amount of $50,119.18 for Ninyo & Moore Geotechnical and Environmental Sciences Consultants (Ninyo & Moore) for additional Environmental Remediation Services and Air Quality Management District (AQMD) "Site Specific" permit at 9255 Imperial Highway In late 2005, the City acquired the property located at 9255 Imperial Highway, formerly known as the Spartan Lacquer and Paint Facility, for roadway construction purposes in conjunction with the extension of Ardis Avenue (now Caring Way) from Congressman Steve Horn Way to Imperial Highway. Upon acquisition of the property, the City demolished and cleared the buildings and removed six underground storage tanks. Upon completion of site clearance, various environmental related testing was conducted. Results of the tests indicated contamination due to elevated concentrations of contaminants in the groundwater. The City prepared a workplan for the soil remediation work and submitted it to the Los Angeles Regional Water Quality Control Board (RWQCB) for review and approval. RWQCB conditionally approved the workplan for soil remediation through the installation and operation of a vapor extraction system including vapor extraction and ground water monitoring wells. Over the years, multiple projects have been completed on the site which have proven to be successful in reducing the level of contaminants. In December 2015, the City retained the services of Stearns, Conrad and Schmidt Consulting Engineers (SCS Engineers) to provide professional environmental remediation services related to the soil remediation efforts and the final site closure with the RWQCB. Staff and SCS Engineers met with the RWQCB to discuss the final closure of the site soil remediation efforts and RWQCB stated that the groundwater sampling and soil vapor extraction (SVE) data continued to detect the presence of low contaminate concentrations of volatile organic compounds and total petroleum hydrocarbons and requested recommendations for continued soil remediation efforts. SCS Engineers reviewed the SVE and groundwater technical reports and sampling data and in March 2016, staff and SCS Engineers once again met with RWQCB to discuss the requested recommendations for continued remediation efforts and submitted an Environmental Data Review and Recommendation Report to RWQCB for review and approval. Consequently the City received a letter from RWQCB with the approval of remediation recommendations for resuming site assessment and cleanup. 0 Capital r • -nt Project No. March 13, 2018 In June 2016, staff issued a Request for Proposal for the environmental remediation services based on the RWQCB's approved recommendations and continued soil remediation efforts. In July 2016, four proposals were received from environmental remediation consulting firms. The proposals were reviewed and evaluated and Ninyo & Moore received the highest ranking based on their proposal which demonstrated a thorough understanding of the city's soil remediation needs, effective work program, relevant technical experience, ability to meet the city's schedule and cost effectiveness. In September 2016, the City retained the services of Ninyo & Moore for the environmental remediation services at subject site in the amount of $145,359.68. In December 2016, Ninyo & Moore commenced the environmental remediation services in accordance with Environmental Data Review and Recommendation Report approved by RWQCB. These environmental remediation services included project coordination and preparation of site-specific Health and Safety and Quality Control/Quality Assurance Plans, installation of new soil vapor extraction equipment, vapor sampling and analysis at eight vapor extraction wells, installation of new soil vapor probe wells, groundwater monitoring and submission of technical reports to the RWQCB among other soil remediation services. During the remediation efforts in 2017 additional services beyond the original scope of Ninyo & Moore's work were incurred resulting in additional cost of $43,782.08. The services included but not limited to; coordination of Los Angeles County Department of Health and City permit fees, disposal of material generated from drilling of vapor probe wells, replacement of the carbon material in the carbon absorption tanks, additional reporting requirements requested by the RWQCB and installation and operation of a Catalytic Oxidation soil vapor extraction equipment (see Attachments 1 and 2). On February 27, 2018, Ninyo & Moore, SCS Engineers and staff met with RWQCB to discuss soil vapor extraction and groundwater monitoring data from the latest technical report submitted to the RWQCB. RWQCB acknowledged that based on the analysis data the concentration of contaminants in the soil has been significantly reduced and contaminants concentration in the groundwater has also decreased. Although the level of contaminants is still on a downward trend they have not yet reached asymptotic levels as required. Therefore, continued soil remediation efforts will be required by the RWQCB. Staff is currently working with RWQCB, Ninyo & Moore and SCS Engineers to summarize the future soil remediation activity requirements which is anticipated to be presented to the City Council at a future date. Additionally, in anticipation of the continued soil remediation efforts, a new "Site Specific" permit will be required by the AQMD. Obtaining a new AQMD "Site Specific" permit is a lengthy process. Therefore, to avoid any further delays associated with the required continued soil remediation activities securing an AQMD "Site Specific" permit in a timely manner is necessary. The permit will be obtained through services of Ninyo and Moore at the cost of $6,337.10 (see attachment 3). q Capital I rov rj o. 17-01 Environmental Remediation Services at 9255 Imperial i y March 13, 2018 The total cost for incurred additional environmental remediation services and obtaining the required AQMD "Site Specific" permit is $50,119.18. Sufficient funds have been budgeted in the Fiscal Year 2017-18 Capital Improvement Program under Account No. 51-1-6583 to cover these services.

This service is being provided under the City's existing Purchase Order Number 33-11039 that includes continuation of groundwater monitoring and the operation of a remediation system consisting of SVE and carbon adsorption under a various locations permit, in accordance with our proposal, dated July 28, 2016. The following additional scope of work item is anticipated to be performed before the end of the contract period. SCOPE OF WORK Ninyo & Moore will perform the following environmental services for the remediation of volatile organic compounds (VOCs) -contaminated soil vapor at the site. Task 1 — Application for a Site -Specific SCAQMD Permit • Prepare and submit an application for a site specific SCAQMD Permit to operate the existing SVE and treatment system equipped with either a Catalytic Oxidizer or granular activated carbon vessels, • SCAQMD Permit Fee. ASSUMPTIONS Listed below are our assumptions for estimating the costs to complete the scope of work. , '{k 11 010, 5 W6 Pllolt't 145) 753 1070 t (941,J 753 70 1 in • • Project No. 17-01 Environmental Remediation Services at 9255 Imperial Highw March 13, 2018 1 9255 Imperial Highway February 28, 2018 Downey, California Project No. 209850001 • The site-specific permit application will be submitted to the SCAQMD without the need for expediting. It is our understanding that obtaining a site-specific permit may take anywhere from two to four months. Expediting the permit with the SCAQMD would require additional fees (an additional 50 percent of the normal fee). • The permit will not require the notification of the public. This is typically required if there is a school within 1,000 feet of the property line, or if cancer risk to nearby receptors is considered too great. Based on our preliminary research, it is our understanding that this will not be necessary. RECOMMENDATION Based on the sustained elevated influent VOC concentrations measured at the SVE system, Ninyo & Moore recommends initiating the process to obtain a site-specific SCAQMD permit for the site at the earliest possible time. It is our understanding that obtaining a site-specific permit may take anywhere from two to four months. The existing SVE system at the site is currently being operated under a various -locations permit that is valid for operation for a maximum of 12 months at a site. FEE AND SCHEDULE The cost breakdown for the additional scope item listed above are provided on the attached Table 1, Breakdown of Estimated Fee. Our proposed schedule for this project may be extended depending on the implementation of this change and the required duration for cleanup of the site.
