They are both hot heating oil tank closures. Soil was removed following the tank removal and a monitoring well installed at the 95-4647 site. Soil and water came back clean and the case closed. The other site included tank removal along with 15 tons of soil. There was a potable well approximately 65 feet up-gradient of that tank basin which was sampled and yielded no petroleum constituents. Please keep in mind that sample analysis was not as precise as it is now but in this situation with the distance between the former basins and your proposed well location there should not be a risk of impact from these releases. The good news is that in the 1990s the standard operating procedure was to pull the tank, remove lots of soil, sample. This eliminated most contamination from that period of time. I would tell you that specifying a minimum casing isn’t necessary but I would rather recommend as you mentioned installing the casing into bedrock and grouting. That just makes good sense in case there is an unknown tank in the vicinity. I have included copies of the closure reports for your review. If you have any additional questions just let me know. Have a good one. David From: Kirtley, Joshua (VDH) Sent: Wednesday, September 04, 2013 9:31 AM To: Fitt, David (DEQ) Subject: New Hope Community Church Well Permit Good morning, David. Hope that you’re doing well. I am evaluating a proposed well site here in Albemarle for the New Hope Community Church and I wanted to get your feedback on the proximity to a couple of known release sites. I have attached a PDF showing the approximate well site in relation to the known releases in the area. Please review and let me know if you have any questions or concerns. As far as the well construction is concerned, I am open to any suggestions that you may have. At this point, I have no problem with requiring a minimum of 50’ of casing and grout even though 20’ would suffice by the Regulations. I also think that it would be a good idea to case and grout to bedrock. Would you do anything different given your knowledge of the known releases in the area? I appreciate your time in advance. Let me know if you need anything further.
