Terms and Conditions for a Discharge from a Water Treatment Plant Owned and Operated by

a Municipality, or by a Water District Created by a Special or General Act of the Massachusetts Legislature A Sewer Use Discharge Permit for a water treatment plant owned and operated by a municipality, or by a water district created by a special or general act of the Massachusetts Legislature, may authorize the discharge of Sludge and filter backwash directly or indirectly into the Authority Sewerage System. Prior to issuing such Permit, the Authority may require the Person requesting to make such discharge to submit a detailed hydraulic analysis of the Sewers involved to ensure that adequate capacities are available. If Combined Sewers are involved, or if a separate Sewer that is involved does not have adequate capacity to transport existing peak dry or wet weather flows, the analysis shall propose facilities the Person will use to prevent its Discharge from having an adverse impact on a Municipal Sewer or the Authority Sewerage System, including how the Person will control its Discharge so that its Discharge does not cause, contribute to, or prolong a combined sewer overflow event or a sewer surcharge. Such Permit may contain the following conditions, in addition to the conditions listed in 360 CMR 10.053: (1) That the Person implement measures required by the Authority to prevent any adverse impact on a Municipal Sewer or the Authority Sewerage System, based upon the detailed hydraulic analysis of the Sewers involved, the facilities the Person proposed to use to control its discharge, and other information available to the Authority; (2) That the Person recycle or reuse its filter backwash to the maximum extent practicable without degrading water quality or causing health or safety problems; and (3) Any other requirement the Authority believes is necessary to ensure that the discharge complies with 360 CMR 10.000.
