Village of Wolcott, NY Article IX Discharge Restrictions

§ 121-84 Pretreatment standards.

All users of the Village POTW will comply with all standards and requirements of the Act and standards and requirements promulgated pursuant to the Act, including but not limited to 40 CFR 406 through 471.

§ 121-85 General prohibitions.

A. No user shall contribute or cause to be contributed, in any manner or fashion, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of the POTW. These general prohibitions apply to all such users of a POTW whether or not the user is subject to National Categorical Pretreatment Standards, or any other national, state, or local pretreatment standards or requirements.

B. Without limiting the generality of the foregoing, a user may not contribute the following substances to the POTW:

(1) Any solids, liquids, 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 a fire or an explosion or be injurious, in any way, to the POTW, or to the operation of the POTW. At no time shall both of two successive readings on a flame-type explosion hazard meter, at the point of discharge into the system (or at any other point in the system) be more than 25% nor any single reading be more than 40% of the lower explosive limit (LEL) of the meter. Unless explicitly allowable by a written permit, prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, carbides, hydrides, and sulfides, and any other substance which the Village, the state, or the EPA has determined to be a fire hazard, or hazard to the POTW.

(2) Solid or viscous substances which may cause obstruction to the flow in a sewer or otherwise interfere with the operation of the wastewater treatment facilities. Unless explicitly allowable by a written permit, such substances include, but are not limited to, grease, garbage with particles greater than 1/2 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, plastics, gas, tar asphalt residues, residues from refining or processing fuel or lubricating oil, mud, or glass or stone grinding or polishing wastes.

(3) Any wastewater having a pH less than 6.5 or greater than 9.0, unless the POTW was specifically designed to manage such wastewater, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment, and/or POTW personnel.

(4) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants (including heat), 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 POTW, 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 Act.

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

(6) Oils and grease. Any commercial, institutional, or industrial wastes containing fats, waxes, grease, or oils which become visible solids when the wastes are cooled to 10° C. (50° F.); any petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin, in excess of 100 mg/l or in amounts that will cause interference or pass-through.

(7) Any wastewater which will cause interference or pass-through.

(8) Any wastewater with objectionable color which is not removed in the treatment process, such as, but not limited to, dye wastes, and vegetable tanning solutions.

(9) Any solid, liquid, vapor, or gas having a temperature higher than 65° C. (150° F.); however, such materials shall not cause the POTW treatment plant influent temperature to be greater than 40° C. (104° F.). The Superintendent reserves the right, in certain instances, to prohibit or limit the discharge of wastes whose maximum temperatures are lower than 65° C.

(10) Unusual flow rate or concentration of wastes, constituting slugs, except by industrial wastewater permit.

(11) Any wastewater containing any radioactive wastes except as approved by the Superintendent, and in compliance with applicable state and federal regulations.

(12) Any wastewater which causes a hazard to human life or which creates a public nuisance, either by itself or in combination, in any way, with other wastes.

(13) Any wastewater with a closed cup flashpoint of less than 140° F. or 60° C. using the test methods specified in 40 CFR 261.21.

(14) Any pollutants which result in the presence of toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems.

§ 121-86 Concentration-based limitations.

The Village of Wolcott has no industrial dischargers capable of discharging substances of concern at this time. This section will be modified and specific limits added before any industrial user is permitted into the sewer district.

§ 121-87 Modification of limitations.

A. Limitations on wastewater strength or mass discharge contained in this Part 1 may be supplemented with more stringent limitations when, in the opinion of the Superintendent:

(1) The limitations in this Part 1 are not sufficient to protect the POTW;

(2) The limitations in this Part 1 are not sufficient to enable the POTW treatment plant to comply with applicable water quality standards or the effluent limitations specified in the POTW's SPDES permit;

(3) The POTW sludge will be rendered unacceptable for disposal or reuse as the Village desires, as a result of discharge of wastewaters at the above prescribed concentration limitations;

(4) Municipal employees or the public will be endangered; or

(5) Air pollution and/or groundwater pollution will be caused.

B. The limitations on wastewater strength or mass discharge shall be recalculated not less frequently than once every five years. The results of these calculations shall be reported to the Village Board. This Part 1 shall then be amended appropriately. Any issued industrial wastewater discharge permits, which have limitations, based directly on any limitations, which were changed, shall be revised and amended, as appropriate.

§ 121-88 Access to user's records.

The Superintendent shall have the authority to copy any record related to wastewater discharges to the POTW.

§ 121-89 Dilution.

A. Except where expressly authorized to do so by an applicable pretreatment standard, no user shall ever increase the use of process water or, in any other way, attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with a pretreatment standard.

B. Dilution flow shall be considered to be inflow.

§ 121-90 Grease, oil, and sand interceptors.

Grease, oil, and sand interceptors shall be provided, when, in the opinion of the Superintendent, they are necessary for the proper handling of wastewater containing excessive amounts of grease, flammable substances, sand, or other harmful substances; except that such interceptors shall not be required for private living quarters or living units. All interceptors shall be of type and capacity approved by the Superintendent and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the owner, at his expense.

§ 121-91 Solid waste grinders.

Solid waste grinders at or serving commercial establishments, institutions or industries shall not discharge into the Village POTW if there is a combined sewer overflow (CSO) on the sewer lines conveying the waste to the POTW treatment plant.

§ 121-92 Rejection of wastewater.

The Village Board may reject a user's wastewater, on recommendation of the Superintendent, when it has been determined that the wastewater contains substances or possesses characteristics which have a deleterious effect on the POTW and its processes, or on the receiving water, or which constitute a public nuisance or hazard. See § 121-120.
