and that CC&V would submit a TR for review and approval by the Division at that time. Response 2a: The "if" condition is limited to what is stated in the second sentence of the second paragraph on the last page of TR-79. CC&V will submit a technical revision for review by DRMS to propose new injection well locations and pipeline rerouting. b. No closure disposition or reclamation/demolition cost are discussed. Please discuss whether the eight foot diameter CMP manhole and infiltration wells will be abandoned in place, sealed, heads removed, etc. and provide a cost estimate for removal of the above ground pipe and other appurtenances to be removed and/or sealed. Response 2b: Manhole reclamation and well abandonment costs CC&V used the 2016 RS Means costs for calculating the increase in reclamation cost. The RS Means estimate for "Selective demolition, manholes & catch basins, manhole top, precast, 8" thick, 4' — 6' deep", (2016 RSMeans #02 41 13.42.0400) is $170.50 each for a total of $170.50. The RS Means estimate for "Selective demolition,water wells,well screen and casing, 6" — 16"' diameter", (2016 RSMeans #02 41 13.76.1000) is $14.65 per liner foot for a total of $5,347.25. A 22% contingency was added to the RS Means demolition cost $1,213.91. The RS Means "B-20" crew was used at 4 hours labor (based off of Davis-Bacon wage rates) resulting in a total of$747.52 to complete manhole and well removal. The project in whole will increase the reclamation costs by a total of$7,479.18. Comment 3: NewFields Figure 1. The acronym "VLP" is used three times on this figure. Please define VLP. Response 3: VLP is a typographical error and should read "VLF". I believe the responses above address the concerns conveyed to us during your inspection.
