(a) A new well is needed to replace an existing small production well in order to: (1) Regain lost well capacity and meet the source capacity requirements established in Env-Dw 405; or(2) Meet current water quality requirements established in Env-Dw 702 through 706; and(b) The supplier of water submits information that demonstrates: (1) The replacement well is needed because:a. The yield from the existing small production well has declined below that needed to meet the water supply source capacity requirements of existing customers; orb. Treatment to meet current drinking water standards is either not possible or not cost-effective;(2) The replacement well will not be used to expand the CWS or to supply water above the approved or established capacity of the well to be replaced;(3) The replacement well will be installed in the same aquifer as that of the well being replaced;(4) The replacement well will meet all setback requirements specified in Env-Dw 305.09; and(5) There is no contamination in the vicinity of the replacement well that is likely to reach the wellhead as a result of the change in the location of the well.N.H.
