Box 388 <br /> Stockton, California 95201-0388 l <br /> RE: Shell Service. Station <br /> 431.5 Waterloo Road <br /> Stockton, California <br /> WIC 4204-7524-2804 <br /> Dear Mr:Sasson: <br /> Pursuant to our telephone conversation, this letter is provided to explain Shell's current ' <br /> plans for this site. <br /> In your letter dated July 10, 4996, which was issued in response to our Soil-Boring. `; <br /> Installation Report dated May 21 1996,you indicated that.Shell could.request closure of <br /> the site in accordance with the format provided in Appendix B of the.Central Valley _. <br /> Regional Water Quality Control Board's (CVRWQCB) guidelines. , <br /> - <br /> While we agree that closure of the site is appropriate, it has been our experience that <br /> CVRWQCBhas resisted closing sites with residual petroleum hydrocarbons-in soils. <br /> While the <br /> St <br /> Resource Control Board has endorsed evaluation of these sites using <br /> risk based methods, numerous issues remain to be resolved in.terms of implementation of <br />.r this approach. As this location is,a viable operating service_station, Shell prefers to wait , <br /> until clearer agency policy on closure issues is,available prior to investing resources in <br /> pursuing closure of this site. <br /> In the interim, reports will continue to be submitted on 90 day intervals in accordance with <br /> reporting requirements of the California Administrative Code Title 23 Waters, Chapter 3, <br /> Subchapter 16, Article 5, Section 2652.d. <br /> h <br /> If you have any questions; please call. t' r <br /> �OQ�OFESS/oygl <br /> Sincerely, L , <br /> U,vw <br /> Enviro , Inca a .o f <br /> NO: C46725 <br /> CIV <br /> Diane M.
