Post Office Box 429 Fontana, CA 92334 REUSE OF SOIL FROM RENOWN ENTERPRISES SITE, TRACY, ON THE STOCKTON CROSS-TOWN FREEWAY, SAN JOAQUIN COUNTY Thank you for your letter of 10 June 1986 inquiring about the soil reuse proposal. The Regional Board's letter of 7 April states our concerns with the proposed project. If our information about the composition and reuse of the Renown material is incorrect, a request for an exemption from Subchapter 15 should clarify the matter. Before an exemption could be granted, the Regional Board needs the following information: 1 . A complete characterization of the material. Historical documentation and chemical analyses should be included. 2. A detailed plan for the reuse or disposal of the material. This should include on-going chemical analyses, construction plans, and a detailed description of the methods or conditions which will assure that this material will not adversely affect water quality once it is at its final destination. 3. A plan to monitor the effects of the disposal or reuse on ground water and/or surface water. In your letter, you state that the California Department of Transportation (Caltrans) will not accept the Renown material even if an exemption from Subchapter 15 is granted. Nevertheless, you request the Regional Board continue to process your request for an exemption in the hope that you will convince Caltrans to change its position. Our workload will not permit such an approach. If all proponents of the project wish to proceed with an exemption request, the information discussed in numbers 1 , 2 and 3 above must be provided. At that time, the Regional Board will proceed as expeditiously as possible. There appears to be two related, but separate issues, which must be addressed. First, there is the question of compliance with Subchapter 15 regulations. ( Title 23, California Administrative Code, Section 2510 and following) . These regulations include extensive requirements for discharges of waste to land, in order to protect water quality. A limited exemption is included for materials which are recycled or reused:
