G. Monitoring activities: 1. Groundwater Monitoring: The Corral Hollow Sanitary Landfill operates under Waste Discharge Requirements (WDR) No. 75-115 adopted by the RWQCB. These WDR were issued to the Corral Hollow Sanitary Landfill as a Class II-2 site. (According to the latest requirements of Subchapter 15, the designation for Class II-2 sites has been changed to Class III. ) The WDR for the landfill are in the process of being revised by the RWQCB. In August 1988 the San Joaquin County Department of Public Works prepared a RWD for the landfill. The City of Tracy Department of Public Works is in the process of submitting this RWD for the site to the RWQCB. This RWD, which is Appendix C of this engineering review, will be used by the RWQCB to develop new WDR for the site. In February of 1988, EMCON Associates prepared a report titled, Solid Waste Assessment Test Proposal and Groundwater Monitoring Plan, for the site. This report was submitted to the RWQCB on February 25, 1988 and the CWMB and LEA on March 8, 1988. This report is a two part report which proposed procedures for performance of the GWSWAT at the landfill, and also proposed a groundwater monitoring program to satisfy Subchapter 15. On April 5, 1988, the RWQCB approved the GWSWAT proposal and Groundwater Monitoring Plan for the site. A copy of this letter, which included minor amendments, is contained in Appendix H. The GWSWAT was performed at the site and submitted to the RWQCB on July 1, 1988. Copies of the GWSWAT for the landfill were submitted to the CWMB and LEA on September 7, 1988.
