What is your curt'rnt regulatory <br /> County? . <br /> 3. What is the current regulatory protocol in surrounding counties for managing TPH-contaminated <br /> sites? <br /> 4_ What level of TP3 contarzrination would trigger an immediate cleanup at the site? <br /> 5. Do you feel that the risk assessments and technical reports performed by Dames and Moore for <br /> American Forest Products justify leaving the residual contamination(up to 10,000 mg/kg)in <br /> plane without Wn-further consideration of any type of remediation? <br /> 6. The most recent i ound of monitoring performed at the site indicates that the groundwater level <br /> has risen to appr,:,ximately 52 feet below ground surface. In light of the variability of the <br /> groundwater levi:l,what da you think is the likelihood of your agency ordering Arneriean Forest <br /> Products to remc.ve/treat/contain the residual contamination? <br /> 7. What scenario(s, would cause you to require American Forest Products to remediate the residual <br /> contamination at the site? What type/level of remediation would you prefer/recommend? What <br /> ire? Would you accept insitu bioremediation? <br /> typellevel of remediation would you requ <br /> S. What is the role.)f the California Regional Water Quality Control Board in this situation? What <br /> is their opinion cf what's going on at the site? Can they require remediation separate from what <br /> your agency wol.dd require? <br /> 9. Dames and Moc re and American Forest Products' lawyers have indicated that based on the <br /> infamous "Lawrence Livermore"report,the residual contamination should be allowed to be left <br /> in place and no lurther actions are warranted(other than monitoring). What is this report? <br /> Could you get m e a copy of it? In a nut shell,what does it entail? Do you feel the report can be <br /> used to effectively defend the course of actions being taken at the site by American Forest <br /> Products? <br /> 10.What is your W.e on the other contamination issues at the site: 1. the solvent contamination in <br /> the groundwater and 2.the pentachlorophenol contamination? <br /> I really appreciate y sur help.
