The Department may require modification of such rules and regulations as needed to address any violations of any applicable law, regulation or permit. Upon written request, the rules and regulations for sewer use shall be submitted to the Department. The rules and regulations shall be implemented and enforced by the sewer system authority.

If bypassing due to an emergency condition occurs, the Department shall be notified immediately in accordance with 314 CMR 12.03(8). Such notification or its acknowledgement shall not be construed as permission by the Department to discharge wastes in contravention of the Massachusetts Water Quality Standards.(8) Persons owning or operating a sewer system shall report bypasses and/or overflows as follows: (a) In the event of an anticipated bypass or sanitary sewer overflow, the owner or operator shall provide notification to the Department on a form approved by the Department, at least ten days prior to the event, if possible.(b) In the event of an unanticipated bypass or sanitary sewer overflow, as soon as the owner or operator has knowledge of the bypass or sanitary sewer overflow but in no event later than 24 hours after its first occurrence, the owner or operator shall provide notification to the Department, on a form approved by the Department, of such an event.(c) Within five days of either 314 CMR 12.03(8)(a) or (b), the owner or operator shall provide the following information to the Department, on a form approved by the Department: All the activities that led up to the event; steps taken to minimize the impact of the event on public health, safety and the environment; and, steps taken to prevent such an event from happening in the future.(9) The Department may require that all valved waste bypass lines or outfalls which discharge to the waters of the Commonwealth have a seal installed that will be broken whenever the valve is opened. Such seals shall not be replaced without the approval of the Department or its authorized representatives. A schedule for periodic testing of valves must be approved by the Department.(10) All flow regulators and other like devices in a sewer system shall be maintained in a manner preventing discharge at less than the designed overflow rate, and in no instance at less than the dry weather flow conditions if the designed overflow rate is not known.(11) Any person operating a sewer system or wastewater treatment facility constructed after January 1, 1940 shall maintain a permanent and adequate sets of plans for such facility. Any person operating sewer systems or wastewater treatment facilities constructed on or before January 1, 1940 shall maintain the permanent and adequate sets of plans which were available at the time of adoption of 314 CMR 12.00. Sewer system plans shall indicate location, size, slope and type of material comprising the pipe and any appurtenances.(12) All records referred to in 314 CMR 12.07 and all plans and descriptions of wastewater treatment facilities and related appurtenances required by 314 CMR 12.03(11) shall be made available to the Department upon request.(13) Notwithstanding any other provision of 314 CMR 12.00, a POTW may accept and process organic material as defined in 310 CMR 16.02: Definitions, in anaerobic digesters operated at its wastewater treatment facility with prior written approval of the Department.
