(1) Any liquids, solids or gases which by reason of their nature or quantity are, or may be, sufficient either alone or by interaction with other substances to cause fire or explosion or be injurious in any other way to the POTW or to the operation of the POTW. At no time, shall two successive days readings on an explosion hazard meter, at the point of discharge into the system (or at any point in the system), be more than 10 percent nor any single reading be 20 percent or more of the lower explosive limit (LEL) of the meter. Prohibited materials include, but are not limited to: gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides and any other substances which the B.S.A., city, State or EPA has notified the user is a fire hazard or a hazard to the system.

(2) Solid or viscous substances which may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater treatment facilities such as, but not limited to: grease, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, wood, plastics, gas, tar, asphalt residues, residues from refining, or processing of fuel or lubricating oil, mud, or glass grinding or polishing wastes.

(3) Any water or wastes having any corrosive property capable of causing damage or hazard to structure, equipment of the sewer system, or personnel employed in its operation.

(4) Any water or wastes containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the sewage treatment plant effluent, or to exceed the limitation set forth in a categorical pretreatment standard. A toxic pollutant shall include, but not be limited to, any pollutant identified pursuant to section 307(a) of the Clean Water Act.

(5) Any water or wastes containing any chemical or biological constituent or having physical characteristics which could cause interference with any POTW wastewater treatment process.

(6) Any noxious or malodorous liquids, gases, or solids which either singly or by interaction with other wastes are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for maintenance and repair.

(7) Any garbage containing particles greater than one-half inch in any dimension. The installation and operation of any garbage grinder equipped with a motor of three-fourths horse power (0.76 hp metric) or greater shall be subject to the review and approval of the general manager.

(8) Materials which exert or cause discolorations, such as, but not limited to, dye waters and vegetable tanning solution.

(9) In no case, shall a substance discharged to the authority's facilities cause the authority to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under section 405 of the Clean Water Act; any criteria, guidelines, or regulations affecting sludge use or disposal developed pursuant to Federal, State or local laws and regulations.

(10) Any substance which will cause the authority to violate its N.P.D.E.S./S.P.D.E.S. permit or the receiving water quality standards.

(11) Any substance or wastewater which causes a hazard to human life or creates a public nuisance.

(1) No person shall cause or contribute to an illicit discharge, either directly or indirectly, to any storm sewers. These general prohibitions also apply to all industrial users of the authority's facilities whether or not the user is subject to national pretreatment standards or any other national, State or local pretreatment requirements. The following activities are exempt from the requirements of this section:

(2) The above prohibition shall not apply to any discharge permitted under a SPDES permit, waiver, or waste discharge order issued to the user and administered under the authority of the N.Y.S.D.E.C., provided that the user is in full compliance with all requirements of the permit, waiver, or order and other applicable laws and regulations, and provided that written approval has been granted for any discharge to the MS4.

(3) Except with the approval of the general manager, or as otherwise provided in these regulations, no storm water connection from any building or yard, nor any drain from any catch basin, lake, swamp, pond, or swimming pool, nor any outlet for surface runoff, storm water or ground water of any kind shall be connected to public sanitary sewer or to any private sanitary sewer connected to any such public sanitary sewer.

(4) Within any area served by a sanitary sewer and a separate storm sewer, no storm water shall be allowed to enter waste or vent pipes from any building. Within any such area no down spout, roof leaders, gutters, other pipes, or drains such as channels which may at any time carry storm water surface drainage derived from hydraulic pressure or from well points, cooling water or lake water shall be connected with any sanitary sewer, but must be connected to said storm sewer.

(5) Upon notification to a person that he is engaged in activities that cause or contribute to violations of the B.S.A. or city's MS4 SPDES permit authorization, that person shall take all reasonable actions to correct such activities such that he no longer causes or contributes to violations of the B.S.A. or city's MS4 SPDES permit authorization.

(6) No person shall engage in any activities that cause or contribute to a violation of the authority's SPDES stormwater discharge permit or the authority being subject to the following special conditions:

(7) Upon notification to a person that he or she is engaged in activities that cause or contribute to violations of the authority's SPDES stormwater discharge permit authorization, that person shall take all reasonable actions to correct such activities such that he or she no longer causes or contributed to violations of the authority's SPDES stormwater discharge permit authorization.

(1) No person shall discharge or cause to be discharged into the public sewerage system any substance or wastes which exceed the limits established below:

(2) For facilities with multiple outfalls to the public sewer, the limits established above shall apply to each individual outfall. The exceptions to this are mass limits and total phenol. Mass discharge limits issued to any facility under the BPDES permit system shall apply to the total discharge from all outfalls at that facility. The phenol limit shall also apply to the composite of all discharges from a facility.

(1) No industrial user shall ever increase the use of process water or, in any other way, attempt to dilute a discharge as a means for obtaining compliance with any prohibited or limited discharge requirement of these regulations or any Federal or State pretreatment requirement.

(2) The authority may impose mass limitations on industrial users which are using dilution to meet any requirement of these regulations or in other cases where the imposition of mass limitations is appropriate.

(1) In the case of an accidental discharge, it is the responsibility of the user to immediately telephone and notify the B.S.A. treatment plant of the incident. (The 24-hour B.S.A. telephone No. is [716] 883-1820 or, if first number is busy, call [716] 853-2459). The notification shall include location of discharge, type of waste, concentration and volume, and corrective actions being taken. Within five days following an accidental discharge, the user shall submit to the general manager a written report describing the cause of discharge and the measures which will be taken by the user to prevent recurrence of the noncompliance.

(2) Notwithstanding other requirements of these regulations, as soon as any person responsible for a building, facility or operation, or responsible for emergency response for a building, facility or operation has information of any known or suspected release of materials which are resulting or may result in illicit discharges or pollutants discharging into the MS4, that person shall take all necessary steps to ensure the discovery, containment and cleanup of such release. In the event of such a release of hazardous materials, emergency response agencies of the occurrence via emergency dispatch services shall be notified immediately by the owner or operator. In the event of a release of non-hazardous materials, the B.S.A. shall be notified in person or by telephone or facsimile no later than the next business day by the owner or operator. Notifications in person or by telephone shall be confirmed by written notice addressed and mailed to the B.S.A. within three business days of the telephone notice. If the discharge of prohibited materials emanates from a commercial or industrial establishment, the owner or operator of such establishment shall also retain an on-site written record of the discharge and the actions taken to prevent its recurrence. Such records shall be retained for a least three years.

(3) Compliance with this section of these regulations shall not relieve the user of other liability or expense for damage to the authority's facilities or other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties, or other liability which may be imposed by this article or other applicable law.

(1) Where the general manager has identified illicit discharges or activities contaminating stormwater, the B.S.A. may require implementation of best management practices (BMPs) to control those illicit discharges and activities.

(2) The owner or operator of a commercial or industrial establishment shall provide, at their own expense, reasonable protection from accidental discharge of prohibited materials or other wastes into the MS4 through the use of structural and non-structural BMPs.

(3) Any person responsible for a property or premise, which is, or may be, the source of an illicit discharge or an activity contaminating stormwater, may be required to implement, at such person's expense, additional structural and non-structural BMPs to reduce or eliminate the source of pollutant(s) to the MS 4.

(4) Compliance with all terms and conditions of a valid SPDES permit authorizing the discharge of stormwater associated with industrial activity, to the extent practicable, shall be deemed compliance with the provisions of this section.
