Code of Massachusetts Regulations › 310 CMR - DEPARTMENT OF ENVIRONMENTAL PROTECTION › Title 310 CMR 71.00 - Industrial Wastewater Regulations For Photo Processors And Printers › Section 71.06 - Supplemental Requirements for Photo Processors and Printers

Current through Register 1525, July 5, 2024
(1) Photo processors and printers shall not
			 discharge industrial wastewater to the ground without a groundwater permit
			 pursuant to
			 314 CMR 5.00:
Ground
			 Water Discharge Permit Program
, and shall not discharge industrial
			 wastewater to surface water without a permit pursuant to
			 314 CMR 3.00:
Surface
			 Water Discharge Permit Program
. Discharge of industrial wastewater to
			 a septic or on site disposal system is prohibited.
(2) Photo processors and printers subject to
			 310 CMR 71.00 that use silver
			 recovery systems with cartridges or non-cartridges shall comply with the
			 general and specific prohibitions listed in 310 CMR 71.06(2)(a) and (b):
(a)
General
			 Prohibitions
. No person shall discharge or cause to be discharged
			 to a POTW any substances, materials or wastewaters that can harm the sewers,
			 wastewater treatment process, or equipment; have an adverse impact on the
			 receiving waters or can otherwise endanger life, limb, public property or
			 constitute a nuisance. In addition, no person shall discharge hazardous waste
			 or allow the discharge of hazardous waste through any sewer connection.
In determining the acceptability of these wastewaters,
				consideration shall be given to such factors as the quantities of such
				wastewaters in relation to flows and velocities in the sewers, materials or
				construction of sewers, nature of the wastewater treatment process, capacity of
				the wastewater treatment process, degree of treatability of such wastewaters in
				the wastewater treatment plant, and other pertinent factors. Pollutants
				introduced into POTWs by a non-domestic source shall not pass through the POTW
				or interfere with the operation or performance of the works. These general
				prohibitions and the specific prohibitions listed in 310 CMR 71.06(2)(b) apply
				to all non-domestic sources introducing pollutants into a POTW whether or not
				the source is subject to other pretreatment standards or any other Federal,
				State or local pretreatment requirements.
(b)
Specific
			 Prohibitions
. In addition, the following pollutants shall not be
			 introduced into a POTW:
1. Pollutants which
			 create a fire or explosion hazard in the POTW;
2. Pollutants which cause corrosive
			 structural damage to the POTW, but in no case discharges with pH lower than 5.5
			 or more than 10.0, unless the works is specifically designed to accommodate
			 such discharges;
3. Solid or
			 viscous pollutants in amounts which will cause obstruction to the flow in the
			 POTW resulting in interference;
4.
			 Any pollutant, including oxygen demanding pollutants discharged in a flow rate
			 and/or pollutant concentration which will cause interference with the
			 POTW;
5. Heat in amounts which will
			 inhibit biological activity in the POTW resulting in interference, but in no
			 case heat in such quantities that the temperature at the POTW treatment plant
			 exceeds 40 E C (104 E F) unless the Division, upon request of the POTW,
			 approves alternate temperature limits.
