We understand per your letter of April 4, 1991, improvements to the site will be designed such that disturbance of the material will not be necessary. Should disturbance or excavation of the material become necessary for any reason, it would then be considered hazardous waste and all laws and regulations concerning the handling, transportation and disposal of such waste would apply. Please provide copies of this letter to all those whom it may concern. If you or others involved in the project have further questions, please contact me at the number below. ~Chra's Burge~ Hazardous Materials Specialist IV Hazardous Materials Management Program CB:jg cc: File 2700 "M" STREET, SUITE 300 BAKERSFIELD, CALIFORNIA 93301 (805) 861-3636 FAX: (805) 861-3429 BCE Basic Compliance Engineering Directors: Malcolm H.

Dear Chris, As we discussed this morning, the owners of this property respectfully request your approval to retain the soil in place and design around it so that it is not disturbed in the installation of utilities or construction. As can be seen in Appendix A Laboratory Results,the sump bottom sample from 5'(Lab Is961) · was found to contain concentrations of barium and lead above the STLC but well below the TTLC. The sample taken from 1' below the base of the sump at a depth of 6'(Lab#962) did not contain any heavy metal constituents in concentrations above the STLC or TrLC. In fact no barium or lead were found in that sample suggesting that little or no migration of the heavy metals has taken place in the 24 years since the well was abandoned.

A Caltrans Site, four miles east of here, just north of the intersection of Rosedale Highway and Highway 99, with a groundwater level of 52.5', and a TTLC lead level of 130 mg/kg, was found by the Regional Water Quality Control Board to be "within acceptable limits" and determined that it was unnecessary to remove the 2 contaminated dirt frOm the area. They established that it had not contaminated the groundwater as we have established that there has been little or no vertical migration. Thus, we believe that retaining the soil in place and designing the development such that the material will not be disturbed will adequately mitigate any environmental hazard from this material. We respectfully request your approval of this proposal at your earliest convenience. Sincerely yours, Malcolm H. Mossman BCE Basic Compliance Engineering Directors: Yak:olin H.
