Elevation Site MCCORMICK & BAXTER CREOSOTING (Continued) Activity: REMOVAL ACTION Activity Status: ANNUAL WORKPLAN - ACTIVE SITE Activity: USE, IORSE, FFA, FFSRA, VCA, EA Activity Status: ANNUAL WORKPLAN - ACTIVE SITE Activity: DISCOVERY Activity Status: ANNUAL WORKPLAN - ACTIVE SITE Background: McCormick and Baxter (Mc&B) is located adjacent to Old Mormon Slough at the Port of Stockton area of Stockton. Mc&B is a wood treatment company. Poles were impregnated with pentachlorophenol (PCP), creosote or metals for preservation. Drippage, spillage and past waste management practices have contaminated the entire site (both soils and groundwater). In July 1984, Mc&B stipulated to a Director's Order with DHS for oversight of its investigation and mitigation efforts. Mc&B filed for Chapter 11 Bankruptcy in November 1988. A Reorganiza- tion Plan was approved by the Court in November 1990. Mc&B has conducted six years of RI work. PCP and creosote contamination has migrated into groundwater and has moved at least one-half mile offsite. Several industrial wells on the edges of the plume have been impacted. Fugitive dust from the site has been sampled and may be a public health threat. The site has been fenced to prevent tres- passing and bermed to prevent storm water runoff. A public health assessment and a feasibility study were con- ducted. A Phase I RAP was prepared which identified activities that stabilized the site. However, the Reorganization Plan, which allocated some funding for site remediation, was not suffi- cient to implement all these actions at once. The RAP document will serve as a conceptual plan for remediation. Since assuming the lead at the site, EPA has completed exten- sive work at the site. This work has included surface and sub- surface soil sampling on-site and off-site, sediment sampling from Old Mormon Slough, New Mormon Slough, and areas around the Port of Stockton, sampling of 43 on-siteand off-site groundwater monitoring wells, demolition of on-site structures, and the auctioning of machinery and on-site supplies.
