(1) No dry cleaner shall discharge industrial
wastewater to the ground, septic system, or other on-site disposal system
without a groundwater discharge permit pursuant to
314 CMR 5.00, or to surface
water without a permit pursuant to
314 CMR 3.00.
(2) Each dry cleaner with a POTW permit shall
comply with the terms and conditions of that permit.
(3) Each dry cleaner shall comply with the
general and specific prohibitions listed below:
(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 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 the 310 CMR 72.04(3)(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 9.5, 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°C (104°F) unless the Division, upon request of the POTW,
approves alternate temperature limits.
6. Wastewater containing perchloroethylene,
except that separator water may be discharged.
(4) Each dry cleaner that treats industrial
wastewater shall comply with
314 CMR
12.03(3) and
12.04(2).
(5) Dry cleaners using tanks or containers to
store industrial wastewater shall:
(a) use
tanks which:
1. have a containment structure
with 110% capacity of the total volume of all above-ground tanks;
2. have a bell and light alarm in a
conspicuous location if they are remotely/ automatically filled tanks. The
alarm must activate when the level of wastewater reaches 75% capacity of the
tank and the alarm signal must be transmitted to a staffed location. Manually
filled tanks must be provided with visual or sight glass type of level
measurement;
3. are located to
provide year round access for emptying;
4. have odor control as necessary;
5. are made of, or lined with, materials
which will not react with, and otherwise be compatible with the, industrial
wastewater to be stored; and,
6.
are located in a secured storage area which is free of cracks and gaps that is
sufficiently impervious to contain leaks and spills.
(b) use containers which:
1. satisfy requirements set by the Department
of Transportation for transportation of waste off-site, and
2. are located in a secured storage area
which is free of cracks and gaps that is sufficiently impervious to contain
leaks and spills.
(c)
maintain records sufficient to demonstrate that all industrial wastewater is
shipped off-site to the POTW, including, but not limited to, transporter name
and address, dates of shipment, amount shipped, and destination. These records
shall be kept on-site for at least three years.
(d) implement the following operating
procedures and work practices:
1. spill
control measures when filling, emptying or transporting containers
2. report to the local Board of Health within
24 hours any occurrence of spills released to the environment
(6) Wastewater
containing perchloroethylene shall not be evaporated, except that separator
water may be evaporated.
