ll LKMEA • Secured all permits necessary for exploratory excavation, drilling and sampling from the DEH and the Base Environmental Affairs Office • Conducted geophysical surveys to detect and mark all subsurface utilities in the proposed investigation areas • Performed exploratory excavation and soil sampling/analytical laboratory testing (with labor and equipment provided by EWMI, also a KMEA teaming partner listed as part of this proposal for the City contract) to identify areas of petroleum hydrocarbon contamination • Removed 190 tons of petroleum hydrocarbon impacted soil which were shipped and disposed of under a non -hazardous waste manifest at an approved and licensed disposal facility following chemical profiling and characterization. • A combination of on -site mobile laboratory and a fixed -base laboratory was used to accelerate data acquisition, soil clean up confirmation analyses and guide the exploratory excavation crew and reduce potential delays in construction • Backfilled and compacted the excavation to 95% relative compaction due to close proximity to the airfield per the training center specifications • An air rotary drill rig was used to drill and sample from subsurface soils in select locations around the exploratory excavation and along a former above -ground fuel conveyance pipeline to supplement the characterization efforts • All investigation locations were surveyed by a licensed professional land surveyor at the completion of the field activities • All data gathered from the field investigations and report deliverables were uploaded in the State Geotracker Database Title— Lead Piping Inventory Report Location — Marine Corps Recruit Depot (MCRD), San Diego, CA POP —11 /28/17 - 9/30/18 (Est.) Client — Naval Facilities Engineering Command Southwest (NAVFAC SW) Total Value - $397,2459 Client Reference— Marlyn Vasquez, (619) 532-4710, marlyn.vasquez@navy.mil Project Description — This is a currently on -going and active Task Order designed to meet the requirements of the Amended California Senate Bill 1398, KMEA and its teaming partner are tasked to locate and identify all potable water lead pipes and submit a report of the findings. At the conclusion of activities under this project at the Marine Corps Recruite Depot (MCRD) San Diego, the project team will provide a debriefing to the environmental staff on the results of the field survey, areas affected, and reporting. A Health and Safety Plan (HASP) was prepared to adequately cover the fieldwork hazards and mitigation and avoidance measures. The KMEA and its teaming partner prepared a Work Plan describing the plan of action to perform the scope of work and included a schedule in MS Project format.The project team reviewed existing rules and regulations, and MCRD standard operating procedures including applicable Marine Corps Orders and/or Navy Instructions, and interviewed appropriate personnel required to develop the plans. The Project team also performed an assessment of the current Potable Water System and identified sections of MCRD SD that will be affected by the SB 1398, The field survey Is designed to assess compliance with all applicable requirements and collect information as necessary to complete the elements outlined in the Senate Bill 1398. The field survey includes all facilities at the installation including; the distribution systems that are located outside of the facility. The project involves survey of all potable water system locations and will provide information regarding areas identified with pipes that are suspected to contain of lead. The project team will prepare and submit assessment reports explaining the results of compliance assessment. Any maintenance/repairs necessary for compliance will be identified, and recommendations will be made for improving compliance. The project team will include the following information in the assessment report • Identify the areas that are suspected of having lead piping. • Describe methods for accomplishing the survey. • Cost of replacement. • Analyze the Senate Bill 1398 to identify potential compliance problem areas and methods to prevent violations. • Develop or update site maps to identify existing potable water system locations. • Include pertinent site maps and drawings in compatible Geographic Information System (GIS) or automated drafting City of Santa Ana Page 16 June 5, 2018 Various Environmental Services RFP NO.: 18-043
