Silva <br /> Director of Public Works <br /> City of Tracy <br /> 325 E. 10th Street <br /> Tracy, CA 95376 <br /> DELINQUENT REPORTS, 8ORRA,, GLLIIW C:A bfITS SAN JOAQUIN COUNTY <br /> As we discussed on 11 November 1986, the City of Tracy has been delinquent in,' <br /> responding to the following Regional Board requests: <br /> 1. Ground Water Monitoring Proposal <br /> On 3 April 1985 we first requested that the City submit a report describing <br /> the measures necessary to bring Corral Hollow' s monitoring program into <br /> compliance with California Administrative Code, Title 23, Chapter 3, Sub- <br /> chapter 15 . Your proposal to monitor the vadose zone instead of ground <br /> water is acceptable. However, we need to review the details of your vadose <br /> zone proposal prior to the placement of any monitoring holes or equipment. <br /> This proposal can also be used to satisfy your Solid Waste Assessment Test <br /> (SWAT) requirements under the new California legislation. Corral Hollow is a <br /> Rank 2 site, making its SWAT proposal due by 1 April 1987. <br /> 2. Closure Plan Proposal <br /> Provisions B.3. of the Corral Hollow Landfill Waste Discharge Requirements <br /> (WDRs) requires the sub�a�ittal of a written report after the site reaches 75% <br /> of the reported capacity. This report must comply with Subchapter 15. Items <br /> to be adressed include: final cover, post-closure maintenance, ground water <br /> monitoring and financial assurances. <br /> 3. Sludge Handling <br /> I received the sludge handling plan from Darrell Scott. Since January 1986, <br /> our concern has been that sludge disposal is not permitted under the current <br /> WDRs and that the disposal methodology is not in compliance with Subchapter <br /> 15. Subchapter 15 requires: <br /> a. A leachate collection and removal system, (gravel blanket or dendritic <br /> system) . <br />
