No user shall achieve, or attempt to achieve, compliance with
these Regulations by diluting a discharge instead of using proper
pretreatment. The increased use of process water in place of proper
treatment shall be considered dilution and is prohibited by these
Regulations.
Each user shall provide reasonable and appropriate protection
from any discharge, including accidental discharges, in violation
these regulations.
All information and data regarding any user, whether obtained
from reports, questionnaires, permit applications, permits, monitoring
programs, or inspections, may be made available upon request to other
governmental agencies and to the public without restriction.
The Commission shall allow any person, under the supervision of Commission personnel, to inspect any public record regarding a user governed by these Regulations which is in the custody of the Commission and not exempted as described in Article
IX. The Commission may require each person requesting records to pay for copies of the records or to pay the expense of the search for the public records.
No person shall discharge or cause or allow to be discharged,
directly or indirectly, into the Wastewater Management System any
of the following:
A. Fuel oil, crude oil, lubricating oil, or any other oils or greases
of hydrocarbon or petroleum origin in excess of 15 milligrams per
liter.
B. Any liquid, solid, or gas, including, but not limited to, gasoline,
kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones,
aldehydes, peroxides and methyl ethyl ketone, which by reason of its
nature or quantity is or may be sufficient, either alone or by interaction
with other substances, to create a fire or explosion hazard or to
be otherwise injurious to the Wastewater Management System, or to
receiving waters, including:
(1) Wastewater with a closed cup flashpoint of less than 140° F.(60°
C.) using the test methods specified in 40 CFR 261.21, and measured

or marble dust, straw, shavings, grass clippings, spent grains, spent
hops, tar, asphalt residues, residues from refining or processing

to the flow in sewers, or other interference with the proper operation
of the Wastewater Management System.
D. Any noxious or malodorous liquids, gases or solids, which either
singly or by interaction with other wastes are capable of creating
a public nuisance or hazard to life, or of preventing safe entry into
sewers for purposes of inspection, maintenance or repair.

or concentrated plating solutions, whether neutralized or not.
F. Sludges or deposited solids resulting from an industrial or pretreatment
process.
G. Substances causing noticeable discoloration or turbidity.

65° C., unless an alternative temperature limit is approved, in
writing, by the Commission.
I. Any garbage containing particles larger than 1/2 inch (1.27 centimeters)
in any dimension or particles which will not be carried freely in
the Wastewater Management System.
J. Waters or wastes having a pH lower than 5.5 or higher than 10.5,
or having any other corrosive or injurious properties capable of causing
damage or hazard to structures, equipment, people or the Wastewater
Management System. Excursions from these limits are permitted for
facilities that continuously monitor pH, subject to limitations established
by the in its Sewer Use Regulations, 360 CMR 10.000.
K. Mercury, polychlorinated biphenyls (PCBs), phenanthrene or pesticides,
including, but not limited to, dieldrin, chlordane, 1,1,1-Trichloro-2,2-bis
(p-chlorophenyl)-ethane (4-4 DDT), demeton, endosulfan I, endosulfan
II, endrin, guthion, heptachlor, malathion, methoxychlor, mirex, parathion,
acrolein, aldrin, TDE, DDE, hexachlorocyclohexane, lindane, benzene-cishexachloride
and benzene-trans-hexachloride (BHC), hexachlorocyclopentadiene and
toxaphene.
L. Waters or wastes containing amounts of metal or other materials in
quantities which violate the System's groundwater discharge permit,
including but not limited to: antimony, arsenic, boron, cadmium, chromium
(VI) (hexavalent), copper, cyanide, lead, nickel, selenium, silver,
zinc, chromium, chlorinated naphthalenes, fluoranthene, hexachlorobutadiene,
pentachlorophenol, phenol, phenolic compounds (the following hydroxyl
derivatives of benzene: 2-chlorophenol; 2,4-dichlorophenol; 2,4-dimethylphenol;
4,6-dinitro-o-cresol; 2,4-dinitrophenol; 2-nitrophenol; 4-nitrophenol;
p-chloro-m-cresol; and 2,4,6-trichlorophenol), toxic organics (each
toxic organic not limited elsewhere in these Regulations): 1.0 total
toxic organics 5.0 trichloroethylene.
M. Waters or wastes containing amounts of toxic or objectionable metals
and nonmetals in excess of limits contained in federal or state regulations
or in a groundwater discharge permit.
N. Radioactive wastes or isotopes of such half-life or concentrations
as may exceed limits established by federal or state regulations.
O. Total suspended solids or dissolved solids of a type or concentration
which would inhibit flow in the Wastewater Management System.
P. Materials which exert a biochemical oxygen demand in excess of 400
milligrams per liter or a chemical oxygen demand in excess of 1,000
milligrams per liter or a chlorine demand in excess of limits established
by the Commission.
Q. Waters or wastes containing fats, wax, grease, or oils of vegetable
or animal origin in excess of 100 milligrams per liter or containing
other substances which may solidify or become viscous at temperatures
between 32° and 150° F. (0° to 65° C.). Waters or
wastes containing such substances (excluding normal household waste)
shall exclude all visible floatable oils fats and greases. The use
of chemical, biological or physical means (such as temperature variation,
solvents, enzymes, emulsifying agents, mechanical mixers) to bypass
or release fats, waxes, oils or greases into the Wastewater Management
System is prohibited. Subject to the written approval of the Commission,
a chemical or biological agent may be added to convert the fats, wax,
oil, and grease in a trap to a substance not regulated by these Regulations
if the resulting discharge from the trap will not cause or contribute
to an obstruction or blockage in the sewer or otherwise violate these
regulations. Unless so converted, the fats, wax, oil, and grease contents
of a grease trap shall not be discharged to the Wastewater Management
System. If the discharge concentration for any fats, oils or grease
exceeds 100 milligrams per liter after treatment, the Commission may,
in its discretion, increase the discharge concentration limit on a
case by case basis and apply a monetary charge for the increase.

the person using the bypass has provided the required notices to the
Commission in a timely manner.
U. Any filter backwash not specifically authorized to be discharged
by a permit issued to the discharger by the Commission, any filter
backwash that is not treated to meet the limits and prohibitions established
by the Commission, or any filter backwash which causes or contributes
to a violation of these Regulations.
V. Any trucked or hauled pollutants.
W. Any water or wastewater, not otherwise governed by these Regulations,
containing pollutants at levels which may adversely affect the Commission's
ability to process or dispose of its wastewater residuals in an environmentally
sound and economic manner in accordance with applicable state and
federal requirements.

directly or indirectly into the Wastewater Management System or into
a sanitary sewer tributary thereto any groundwater, dewatering drainage,
subsurface drainage, accumulated surface water, non-contact cooling
water, non-contact industrial process waters, uncontaminated contact
cooling water and uncontaminated industrial process water, or waters
associated with the excavation of a foundation or trench, hydrological
