1.0 INTRODUCTION Environeering, Inc. (EI) has been contracted by Chemical Transfer Co. (Chem. Tr.)to oversee the cleanup at 1033 Stokes Avenue, Stockton, CA,resulting from a release of hydrochloric acid from a rail car on November 25, 2001. Chem. Tr. operates a bulk chemicals transfer terminal at 1033 Stokes Avenue, Stockton, CA. The company transfers materials from rail cars to truck trailers for delivery to users in the Stockton area. At approximately 5:30 AM on November 25, 2001, Mr. Jack Bishop, Environmental Manager, California Tank Lines and Chem. Tr., was notified of an accidental release of 220 baume hydrochloric acid at the Stokes Avenue terminal. Upon arrival at the terminal, Mr. Bishop determined that the release was from the dome of a rail car. After donning appropriate protective equipment,he was able to stop the release, and,with help from Nemergency personnel who arrived on the scene, initiate neutralization of the acid to mitigate its effect on the environment and the surrounding area. Mr. Bishop estimated that approximately 100 gals. of 220 baume hydrochloric acid were released from the rail tank and ran down the tracks. The acid was generally confined to the track area between the rails. Remediation efforts involved neutralizing the hydrochloric acid with lime rock. The lime rock was spread over the contaminated areas. Initially, the hydrochloric acid produced hydrogen chloride fumes, which were dispersed by the wind. The fuming stopped as the acid was neutralized by the lime rock. 2.0 WORK PLAN The contaminated area is under a rail siding, making soil removal for treatment or disposal impractical. Therefore, cleanup will be insitu neutralization of all hydrochloric acid contaminated soil to a pH above 7. Specific actions to be taken include:
