A copy of our <br /> comments, addressed to Mr. Gilbert Jay, has been forwarded to your office. <br /> As you may know, the plan calls for stockpiling of the soils at the Corral <br /> Hollow Landfill for future use as a foundation material for the final cover at <br /> the landfill . The subject report references a 30 October 1985 letter to Renown <br /> Enterprises that states the City will accept the soil as final cover material at <br /> the landfill upon the Regional Board's approval of this method of disposal . <br /> It is our contention that contaminated soils of this nature properly placed, as <br /> set forth in Chapter 3, Title 23, Subchapter 15, Section 2581, do not pose a <br /> threat to the quality of ground or surface waters. We feel this offers a safe <br /> and economic alternative of disposal . <br /> In light of this, please consider this letter our official approval of the <br /> disposal of this soil at the Corral Hollow Landfill . The soils may be stock-- <br /> piled at a location where on-site surface runoff will not enter Corral Hollow <br /> Creek or leave the site and, when needed, be used as the foundation material <br /> for the final cover of the landfill , in accordance to the requirements of <br /> Subchapter 15. This approval is based on the information given in the report of <br /> the soil 's characteristics and properties. <br /> Contaminated soils similar to the soils at the Renown site may also need to be <br /> excavated from Alden Park and possibly from Beck's Development Site. If soil <br /> and water analysis at these sites indicate the soil does not pose a threat to <br /> the waters of the state by being used as foundation material , we would approve <br /> of it's disposal in the same manner as Renown's soils. <br /> If you have any questions regarding this matter, please contact David Brent at <br /> (916) 324-8891. <br /> ANTONI K.
