Section 2822: Regulations
No discharger shall discharge or cause to be discharged, directly or indirectly any of the following described substances or those listed in Section 2875 of this municipality Sewer Use Ordinance into the municipalitys wastewater facilities:
Any liquids, solids or gases which by reason of their nature or quantity are, or may be, sufficient either alone or by interaction to cause fire, or explosion or be injurious in any other way to the operation of the municipal wastewater facilities.
Any solid or viscous substances, including ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch, or manure, capable of causing obstructions or other interferences with the proper operation of the sewer or wastewater facilities.
Any wastewater having a pH less than 5.0 or higher than 9.5 or having any other corrosive property capable of causing damage or hazard to structures, equipment, or personnel of the wastewater facilities.
Any wastewater containing toxic pollutants or poisonous substances, in sufficient quantity either singly or by interaction to injure or interfere with any wastewater treatment process, or which constitutes a hazard to humans or animals, or to create any hazard in waters that receive treated effluent from the municipally owned wastewater treatment facilities. Toxic wastes shall include, but are not limited to, wastes containing cyanide, chromium, cadmium, mercury, copper or nickel ions, or others listed in 40 CFR 401.15.
Any noxious or malodorous liquids, gases, or substances which either singly or by interaction are capable of creating a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for their maintenance and repair, including pollutants which result in the presence of toxic gases, vapors, or fumes.
6. Any substance which may cause the municipalitys wastewater facility to be in noncompliance with sludge use, recycle or disposal criteria pursuant to guidelines or regulations developed under Section 405 of the Federal Act, the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act, or other regulations or criteria for sludge management and disposal as required by the State of Maine.
7. Any substance which may affect the municipal wastewater facility effluent and cause violation of its NPDES Permit and/or State of Maine Waste Discharge License.
8. Any substance containing color that is not removed in the municipally owned wastewater facilities.
9. Heat in amounts which will inhibit biological activity in the municipal wastewater treatment works resulting in interference but in no case, heat in such quantities that the temperature at the influent of the municipal wastewater treatment works exceeds 40 degrees Centigrade (104 degrees Fahrenheit).
10. Any slug, which shall mean any pollutant, including oxygen demanding pollutants (BOD, etc.), released on a single extraordinary discharge episode of such volume or strength as to cause interference at the municipal wastewater facility.
11. Any unpolluted water including, but not limited to, non-contact cooling water.
12. Any wastewater containing any radioactive wastes or isotopes.
13. Any wastewater which causes a hazard to human life or creates a public nuisance.
14. Any medical or infectious waste.
Any waste containing solids of such character and quantity that special and unusual attention is required for their handling.
National Categorical Pretreatment Standards as promulgated by U.S. Environmental Protection Agency (EPA) pursuant to the Act and as codified in 40 CFR Chapter I, Subchapter N shall be met by all dischargers, as applicable. An Application for modification of the National Categorical Pretreatment Standards may be considered for submittal to the Regional Administrator by the municipality when the municipalitys wastewater treatment system achieves consistent removal of the pollutants as defined by 40 CFR 403.7.
State requirements and limitations on discharges to the municipal wastewater facilities shall be met by all dischargers that are subject to such standards in any instances in which they are more stringent than Federal requirements and limitations or those in this or any other applicable ordinance.
The municipality reserves the right to amend this Ordinance to provide for more stringent limitations or requirements on discharges to the municipal wastewater facilities where deemed necessary to comply with the objectives set forth in Section 2820, (A) of this Ordinance.
No discharger shall increase the use of potable or process water in any way, for the purpose of diluting a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the standards set forth in this Ordinance.
F. No dischargers shall discharge wastewater containing concentrations of toxic pollutants that cause the Citys treatment plant discharge to exceed State of Federal water quality limits.
The municipality reserves the right to amend this Ordinance to include concentration-based limits for toxic pollutants. The municipality may impose mass limitations on dischargers in cases where the imposition of mass limitations is deemed appropriate by the municipality.
G. Each discharger shall provide protection from accidental discharge of prohibited or regulated materials or substances established by this Ordinance. Where necessary, facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the dischargers cost and expense. Detailed Slug Control Plans showing facilities and operating procedures to provide this protection shall be submitted to the municipality for review and shall be approved by the municipality before construction of the facility. Each existing discharger shall complete its plan and submit same to the municipality by January 1, 1983. No discharger who discharges to the municipal wastewater facilities after the aforesaid date shall be permitted to introduce pollutants into the system
untilAccidental Discharge Protection Procedures have been approved by the municipality. Review and approval of such plans and operating procedures by the municipality shall not relieve the discharger from the responsibility immediately upon the occurrence of a slug or accidental discharge of substances prohibited by this Ordinance. The notification shall include location of discharge, date and time thereof, type of waste, concentration and volume, and corrective action. Any discharger who discharges slugs of prohibited materials shall be liable for any expense, loss or damage to the municipal wastewater facilities in addition to the amount of any fines imposed on the municipality on account thereof under State or Federal Law.
H. Duty to Comply: The industrial discharger must comply with all conditions of this Ordinance and their industrial discharge permit. Failure to comply may be grounds for administrative action or enforcement proceedings including civil or criminal penalties, injunctive relief, and summary abatements.
I. Bypass of Dischargers Pretreatment Facilities
Bypass is prohibited unless it is unavoidable to prevent loss of life, personal injury, or severe property damage or no feasible alternatives exist.
Upon prior notice to and the approval of the Superintendent, the discharger may allow bypass to occur which does not cause effluent limitations to be exceeded, but only if it is also for essential maintenance to assure efficient operations.
Notification of bypass:
Anticipate bypass. If the discharger knows in advance of the need for a bypass, it shall submit prior written notice, at least ten days before the date of the bypass, to the municipally owned treatment plant Superintendent.
Unanticipated bypass. The discharger shall immediately notify the municipally owned treatment plant Superintendent and submit a written notice to the City within 5 days. This report shall specify:
A description of the bypass, and its cause, including its duration;
Whether the bypass has been corrected; and
The steps being taken or to be taken to reduce, eliminate and prevent a recurrence of the bypass.
