© KMEA Based on our review of the RFP, It is our understanding that the City wishes to procure the services of a qualified environmental consulting firm to conduct Phase II ESA tasks that Include but not limited to: • Collection of soil and water samples from the project site, • Drilling soil borings. • Performing geophysical testing for buried/underground storage tanks and drums. • Installing groundwater monitoring wells and analyze the presence of contamination. Depending on the sample results, additional site investigation and potential remedial actions maybe required. • Preparing Phase II ESA report detailing the compilation and analysis of the data collected including interpretation of the findings and recommendations for any follow-on work required. • Coordinating with local govemment officials and/or contractor to conduct the necessary sample collection, submitting the required forms/reports and obtaining the complete case closure certification. Our approach to conducting Phase II ESAs is In general accordance with the ASTM Standard E1527 and the currently acceptable standard practices in Southern California. Our general approach consists of the following steps: • Attend a kick-off meeting with the client point of contact (City) to discuss the nature and scope of desired survey. • Review previous Investigation results to assess the nature and extent of site contamination identified from soil, groundwater, soil vapor and other media sampling and analyses conducted, where applicable. • Review site history in relation to operational site use and potential for migration of identified contaminants of concern on and offsite. • Determine if the site has been assigned a regulatory case due to past or current release(s) of contaminants. • Upon approval by the City, review the regulatory case files on the State Geotracker database, If the site is under regulatory review, and consult with the agency to gain a thorough understanding of the status of the case In the regulatory process. • Design a scope of Phase II ESA based on the results of historical document review and review of regulatory case history, where available. • Consult with the City and obtain approval of the scope. If the case Is under regulatory oversight, upon approval from the City and with participation of the City Project Manager, attend a meeting with the regulatory agency to discuss the planned approach. • Prepare a work plan and sampling analysis plan in accordance with the KMEA's project quality assurance plan and other applicable quality control standards and to summarize the key elements and approach for the Intended Phase II ESA. • Prepare a site safety plan and community health and safety plan in compliance with the applicable California Occupational Safety and Health Administration (CaIOSHA) rules and regulations to detail the hazards and avoidance and mitigating measures associated with the planned investigations. • Upon approval of the planning documents by the City and regulatory agency, as applicable, start the permit process for any intrusive work that may require agency permits, i.e., exploratory boring, groundwater monitoring well installation or destruction permits, etc. • Obtain scaled site drawings and underground and above -ground utility maps and other Infrastructure maps with details for accurate location of such utilities. • Call the Underground Dig Alert of Southern California to establish a ticket number and clearly mark underground and any above -ground utilities for the proposed investigation locations. • Retain the services of an Independent geophysical contractor to locate and visibly mark -out underground utilities locating and mark out services company to locate and clearly mark out utilities In the areas of the proposed investigation. • Procure qualified and properly licensed subcontractors for drilling, excavation, sampling, analytical laboratory evaluations, waste management and disposal services, based on the elements of work in the approved Investigation work plan. • Perform the on-site evaluations under applicable agency -approved permits and under supervision by a Callfomia-licensed engineer or geologist and a Certified Industrial Hygienist (CIH) Safety professional from KMEA. • Review the analytical data and summarize and tabulate the results and prepare a site investigation location map to share and consult with the City. • Prepare the Phase II ESA report to include a description of field activities, survey and sampling results, conclusions and City of Santa Ana Page 8 June 5, 2018 Various Environmental Services RFP NO,: 18-043 25F-95
