To date, the EHD has not received the directed work plan. As part of the case closure process, your consulting firm, ARCADIS U.S., Inc. (ARCADIS), notified appropriate agencies, property owners and occupants of the pending case closure and of their opportunity to submit comments or questions regarding the pending closure. The EHD received no comments from the public during the sixty-day public participation period that ended on 7 December 2013. It has been more than six months since the public participation period ended. You are now directed to submit the work plan to the EHD within 30 days of date of this letter. Submit a scope of work proposal to the EHD that details the conditions and construction of the wells and the methods and materials to be used to destroy them. To be issued a well destruction permit, the proposal must comply with the San Joaquin County Well Standards requirements, such as: • Wells that have laboratory data from the last sampling event that demonstrate the presence of any contaminants of concern remaining in groundwater are to be destroyed by removing all the contents of the well [well casing (except steel conductor casing), screen, filter pack, grout sealant]; the cleared borehole is then to be sealed with neat cement from the bottom upward to the depth of three to five feet below grade. • All wells that are obstructed, have unknown construction, or are located in an area of known or suspected contamination are to be destroyed by removing all the contents of the well [well casing (except steel conductor casing), screen, filter pack, grout sealant]; the cleared borehole is then to be sealed with neat cement from the bottom upward to the depth of three to five feet below grade.
