The Details

What you need

This report approval is a prerequisite for the issuance of a permit to discharge treated sanitary wastewater in excess of 10,000 gallons per day (gpd) or to discharge treated wastewaters otherwise subject to a groundwater discharge permit. This report approval serves to protect the public health, welfare, and the environment through the control of these discharges onto or into the ground. If, following this report approval, the permittee intends to apply for either an Individual or General Groundwater Discharge Permit, the approved report will be a part of the permit application submittal.

Any individual, business, or organization required to obtain a groundwater discharge permit is subject to the approval of a scope of work and hydrogeologic evaluation pursuant to MGL c. 21, s. 43 and 314 CMR 5.00 (unless exempted in 314 CMR 5.05).
