GEOTECHNICAL ENGINEERING • ENVIRONMENTAL ENGINEERING CONSTRUCTION TESTING & INSPECTION July 22, 2013 Project No. 014-13157 Mr. Johnny Yoakum San Joaquin County Environmental Health Department 1868 East Hazelton Avenue Stockton, California 95205-6232 tz RE: Workplan for Soil Assessment Wilson Way Property (APNs 132-020-08 and -10) 3931-4001 North Wilson Way Stockton, California 95205 Dear Mr. Yoakum: m1_ 2 4 2013 ENV; ENTAI.HLLTH The following is a workplan to conduct a site assessment at the above-referenced site (subject site). On July 4, 2013, Krazan was requested to conduct a Phase II Limited Site Assessment (LSA) for the subject site. The proposed work is based strictly upon the conclusions presented in Krazan's February 28, 2013 Phase I Environmental Site Assessment (ESA) report for the referenced subject site prepared for Capital Access Group, Inc. The proposed work is being conducted in conjunction with a real estate transaction and not by the request of a regulatory agency. BACKGROUND During the course of Krazan's referenced Phase I Environmental Site Assessment (ESA) no evidence of recognized environmental concerns (RECs) was revealed in connection with the subject site. However, the following potential areas of concern (PAOCs) were identified in connection with the subject site: PAOCs Krazan's historical research indicates that the septic system associated with the 4001 N. Wilson Way subject site building has been located on site since this building was reportedly originally constructed in 1991, and that this building appears to have been occupied by a California Department of Fish & Game (Fish & Game) facility since originally constructed. In addition to office and warehouse space, the Fish & Game facility includes several biological laboratories and a shop which, according to records on file with the local regulatory agency, has been used in the past for servicing Fish & Game boats and related equipment. Additionally, information obtained during Krazan's February 20, 2013 site reconnaissance indicates that: 1) ethanol and a 10% formalin solution are utilized in conjunction with specimen preservation operations conducted in the Fish & Game labs; 2) the formalin solutions are currently treated with "Neutralex" to neutralize the formalin waste prior to disposal; 3) the effluent from lab sinks is routed to a sump located adjacent to the south of the 4001 N. Wilson Way building and is subsequently pumped to a plastic aboveground storage tank (AST) located to the west of the building; and 4) the neutralized lab sink waste is pumped from the plastic AST and transported off-site for proper disposal by a contractor. Although no effluent from the Fish & Game labs is currently routed to the on-site septic system, it is unknown exactly how long the labs have been operated on site relative to the existing formalin neutralization system.
