(7) No person responsible for the operation of treatment works shall permit wastes to bypass
the wastewater treatment facility or any portion, unit or part thereof in violation of a discharge
permit, except when approved by the Department due to design limitations. 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.

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

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

4.00: Massachusetts Surface Water Quality Standards, 5.00: Ground Water Discharge Permit
Program, 7.00: Sewer System Extension and Connection Permit Program, 12.00: Operation
and Maintenance and Pretreatment Standards for Wastewater Treatment Works and Indirect
Dischargers, or 20.00: Reclaimed Water Permit Program and Standards is occurring, or that
inadequacies in the design or capacity of a sewer system exist, or that additional extensions or
connections to, or the increased use of, a sewer system will result in violations of the provisions
of the State Act or regulations promulgated thereunder or contribute to the inadequacies in the
design or capacity of the sewer system, the Department may take action it deems necessary to
address such conditions, including but not limited to:
(a) Order the person owning or operating the sewer system to:
1. implement a program for connections to the system that requires the removal or

connections at a ratio determined in the Order;
2. prohibit further connections to or extensions of the sewer system except in
accordance with the terms of the Order;
3. undertake the necessary design, construction and repair work required to eliminate
such discharges, violations or inadequacies; and
