Security Violation 17658 - Site Security: The onsite equipment and building are listed as being in violation of this section and removal of the equipment and repair of the building are the stated actions that will remedy the violation. Section 17658 states: The site shall have a perimeter barrier or topographic constraints designed to discourage unauthorized entry by persons or vehicles. Areas within the site where open storage or pending of hazardous materials occurs shall be separately fenced and properly identified to create an adequate level of security, unless the daily deposition of wastes is conducted under adequate supervision during the site operating hours and provided said waste are covered by the end of the daily site operations. The onsite equipment is from an earlier metals recycling operation. It is presently stored onsite for ultimate use as scrap metal. The building is currently unoccupied and unused. We are not aware of a definition in Title 14 that designates either buildings or scrap steel as a hazardous material. Consequently, we do not see how this particular section applies to either the equipment or the building. Relative to security, the site is fully fenced and the entry gate is locked. In our opinion, this satisfies the security requirements of Section 17658 and no violation appears to exist. SSI pes/Cuts/Grading Violations 17678 - Slopes and Cuts: Since the inspection, the intermediate grading plan has been implemented at the site. Exposed waste has been covered with a one foot soil cap and waste slopes have been cut back to 2:1 (approximately 27). The inspection report notes that the steep soil wall at the northern side of the site is in violation because the maximum grade (30) specified in 17678. The 30° grade requirement is a reasonable maximum for slopes upon which waste is compacted but is not reasonable as a blanket restriction for sideslopes of excavations. The stability of a steep side slope is dependent upon the strength and types of soils in the side slope. With the right combination of conditions and soils, even a vertical soil wall can be stable for an extended period of time. The soil wall in question has been standing for probably 15 to 20 years. Eventhough this is a good indication of stability, Cove Contractors authorized Kleinfelder in December of 1993 to conduct a geotechnical investigation of the steep soil wall on the north side of the site. Cove Contractors is attempting to obtain permission from the adjacent landowner to allow Kleinfelder access to their property for the purpose of advancing a geotechnical boring directly behind the soil wall. Once this permission is obtained, the work will begin immediately. Results of the investigation will be transmitted the San Joaquin County Environmental Health. Thus, no violation appears to exist. 17710 - Grading of Fill Surfaces: As stated earlier, the intermediate grading work has been completed at the landfill and the one foot thick soil intermediate cover has been installed. This work corrects past grading and drainage problems. Thus, no violation appears to exist. 24-215600-H00/CL4-13 (1994) Page 2 of 6 April 29, 1994 KLEINFELDER 2240 Northpoint Parkway, Santa Rosa, CA 95407 (707) 571-1883
