�/ � Clayton ENVIRONMENTAL CONSULTANTS Mr. Robert Wooton Page 3 Stockton Savings Bank Clayton Project No. 70448.00 August 30, 1996 containing pipe insulation be properly repaired, removed or replaced immediately. In the interim, we recommend that access to the basement be restricted to personnel with the appropriate training and equipment to handle ACM. FOLLOW-UP ACTIONS TO THE PREVIOUS PHASE I ENVIRONMENTAL SITE ASSESSMENT As follow-up to the findings and recommendations, the following actions were performed: • According to available information, the pipe insulation in the basement containing asbestos was abated. According to a letter from Clayton to Stockton Savings Banks (Clayton Project No. 54312.00, March 11, 1994), the ACM was abated on March 9, 1994 by Marcor. Clayton performed clearance air monitoring and sampling following the ACM abatement in the basement, and it appears that the ACM abatement passed clearance. Additional abatement was apparently performed in September 1994. According to a September 17, 1994, letter from National Analytical Laboratories (NAL) to PARC Corporation, NAL analyzed clearance air samples which apparently passed clearance guidelines. • On June 6, 1996, Clayton personnel visited the subject property to determine the location of the location of the potential UST under the sidewalk onsite. The findings of this investigation are summarized in Clayton's letter to Stockton Savings dated June 13, 1996 (Clayton Project No. 69790.00). Mr. Richard Silva, a Clayton Geologist, met Mr. Peter Martin of Property Management Experts, and Mr. Odis Haskin of California Utilities Survey, at the subject site. Mr. Martin stated that current and former employees at the building indicated that the building's boiler and associated fuel tank were located in the basement of the building and that a remote fill pipe lead to the tank from the sidewalk in front of the building. According to Mr. Martin, the tank and boiler were removed approximately 15 years ago. No documentation for the removals was available. Mr. Haskin was unable to located a UST beneath the sidewalk using a magnetometer, a radio detection instrument, and an electronic sensing device. However, he was able to trace pipes associated with the boiler from the basement leading toward San Joaquin Avenue. The piping was found to terminate approximately four feet from the building wall at a junction box in the sidewalk. KAB4RXP70448\70448R00.232
