IsLEA site (Naval Industrial Reserve Ordnance Plant) consists of 40 acres occupied by 10 buildings and structures containing numerous laboratories and hazardous materials/hazardous waste (HM/HW) storage locations. Phase II SI and Remedial Action at IRP Site 10, PCB Electrical Transformers, Marine Corps Air Station (MCAS) Miramar, San Diego, CA. Mr. Heironimus was the Project Manager to further investigate horizontal and vertical extent of soil contaminated by PCB releases and spills. Due to the remote location, a number of electrical transformers grouped at two separate locations had been damaged by gunfire and other vandalism. After completion of field work involving drilling and soil sampling and ultimately, remedial action, it was determined that despite low levels of PCB contamination, excavated soil and transformer pads needed to be disposed at a TSCA disposal facility because PCB levels within the originating equipment transformers exceeded 50 ppm. Preliminary AssessmentlSite Inspection (PAISI) at IRP Site 18, Naval Air Station (NAS) Lemoore, Lemoore, CA Under NAVFAC SW Contract N62473-12-D-2012, Mr. Heironimus has been the Project Manager for environmental restoration services at NAS Lemoore. The scope of services includes a PA/SI at IRP Site 18, a recently designated Navy IRP site where potential release of hazardous waste/hazardous substances are believed to have impacted soil, soil vapor, and groundwater. A PA/ is similar to a combined Phase I and Phase II ESA in that the PA includes research of all available historical information and a site visit to identify potential contaminant release sources (Phase 1), followed by the SI where media sampling is performed at areas where contamination may be present at highest concentrations (Phase 11). The PA/SI also estimates human health and ecological risks, and determines if further action is warranted or not. For IRP Site 18, the PA documented a contaminant release at the site, and a Work Plan and Sampling and Analysis Plan were developed and approved by state agencies (Central Valley Regional Water Quality Control Board [RWQCB]; Cal EPA Department of Toxic Substances Control [DTSC]). Field work consisting of drilling, installation of groundwater wells and soil vapor probes, and collection of soil, soil gas, and groundwater samples, was completed in 2017; the PA/SI has recommended further action to define the nature and extent of contamination at IRP Site 18.
