B. Regulations
1. No person shall discharge, release, place or allow to be placed, any wastewater of any nature into any stream, storm sewer, waterway or any other place within the Township other than the sanitary sewers.
2. No user shall contribute, cause or allow to be discharged, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of the sewer system or the WVSA facilities. These general prohibitions apply to all users of the sewer system whether or not the user is subject to any pretreatment standards or requirements or any other federal, state or local pretreatment standards or requirements. A user shall not contribute the following substances to the sanitary sewer system or the WVSA’s facilities:
A. Any liquids, solids or gases which by reason of their nature or quantity are, or may be, sufficient either alone or by interaction with any other substance to cause fire or explosion or be injurious in any other way to the WVSA or to the operation of the WVSA’s treatment plant. Discharges prohibited under this Section shall include, but not be limited to, wastestreams with a closed cup flashpoint of less than 140°F or 60°C using the test methods specified in 40 C.F.R. § 261.21. At no time shall two successive readings on an explosion hazard meter, at the point of discharge into the system (or any point in the system) be more than five percent, nor any single reading over ten percent 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 cause or contribute to a fire hazard or a hazard to the sewer system in the quantities or concentrations discharged.
B. Any wastewater having a pH value less than 6.0 or greater than 11.5 in any grab sample, or a wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment and/or personnel.
C. 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, garbage with particles greater than one-half inch in any dimension, 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, plastic, gas, tar, asphalt residues, mud, or glass grinding or polishing wastes.
D. Any pollutants, including oxygen demanding pollutants (BOD and the like) released at a flow rate and/or pollutant concentration which a user knows or has reason to know will cause interference to the sewer system. In no case shall a discharge have a flow rate or contain a concentration of pollutants that exceed for any time period longer than 15 minutes more than five times the average 24 hour flow or concentration of pollutants during normal operation. Notwithstanding the criteria above, any slug discharge shall be prohibited.
E. Any wastewater having a temperature which will inhibit biological activity in the WVSA treatment plant resulting in interference, but in no case any wastewater with a temperature at the introduction into the WVSA facilities which exceeds 40°C (104°F).
F. Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with any wastewater treatment process, which will cause pass through or interference, or exceed the limitation set forth in a National Categorical Pretreatment standard or local limit.
G. Any discharge which may result in the presence of toxic gases, vapors or fumes within the treatment system in a quantity that may cause acute worker health and safety problems or is sufficient to create a public nuisance or hazard.
H. Petroleum oil, non-biodegradable cutting oil or products of mineral oil origin in amounts that will cause interference or pass through.
I. Any trucked or hauled pollutants, except at discharge points designated by the WVSA.
J. Any substance which may cause the WVSA treatment plant’s effluent or any other product of the WVSA such as residues, sludges or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation or disposal process. In no case shall a substance discharged to the WVSA’s facilities cause the WVSA to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under § 405 of the Act, any criteria guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, 42 U.S.C. § 6962, the Clean Air Act, 42 U.S.C. §§ 7401 et seq., the Toxic Substances Control Act, 15 U.S.C.A. §§ 2601 et seq., or state criteria applicable to the sludge management or disposal method being used.
K. Any substance which will cause or contribute to a violation of the WVSA’s NPDES permit or cause interference or pass through, as established by the local limits adopted by the WVSA.
L. Any wastewater with color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions such as would cause or contribute to pass through or interference.
M. Any wastewater containing any radioactive wastes or isotopes by such half-life or concentration as may exceed limits established by the Executive Director in compliance with applicable state or federal regulations.
N. Any substance which causes a hazard to human life or creates a public nuisance.
3. When a local limit has been developed to implement any of the above prohibited waste standards, compliance with the local limit shall be deemed compliance with the prohibited waste standard unless the user has reason to know that the discharge, notwithstanding the local limit, has a reasonable potential to cause interference or pass through.
(Ord. 2012-4, 9/13/2012, § 2.1)
Upon the promulgation of National Categorical Pretreatment Standards for a particular industrial category or subcategory, the national standards, if more stringent than limitations imposed under this Part 3 for sources in that subcategory, shall immediately supersede the limitations imposed under this Part 3. The Executive Director shall notify all affected users of the applicable reporting requirements under 40 C.F.R. § 403.12. However, failure to notify a categorical user of the applicable regulations shall not act to excuse any such user from its duty to comply with applicable law.
(Ord. 2012-4, 9/13/2012, § 2.2)
No user shall contribute or cause to be contributed any discharge which by nature shall cause an upset in the performance of the WVSA’s treatment system or pass through or interference such that the WVSA will violate or will be in danger of violating any provision of its NPDES permit or applicable state or federal regulations.
(Ord. 2012-4, 9/13/2012, § 2.3)
1. The WVSA will develop local limits as set forth in 40 C.F.R. § 403.5, and such other local limits as it deems advisable for the safe, efficient and reliable operation of the sewer system and the WVSA facilities. Local limits shall be applicable to such users as WVSA shall designate including, but not limited to, all industrial users.
2. WVSA may develop equivalent mass limits or equivalent concentration limits to implement categorical pretreatment standards when requested by a categorical industrial user, pursuant to the provisions at 40 C.F.R. §§ 403.6(c)(5) and (6).
(Ord. 2012-4, 9/13/2012, § 2.4)
No user shall ever increase the use of process water or, in any way, attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the National Categorical Pretreatment Standards, or in any pollutant-specific limitations developed by the WVSA or the Commonwealth; provided, however, that dilution may be an acceptable means of complying with certain of the prohibitions set forth in § 18-311, e.g., the pH and temperature prohibitions, if such dilution is authorized by an industrial wastewater discharge permit.
(Ord. 2012-4, 9/13/2012, § 2.7)
