§ 22-135. Prohibitive discharge standards.

(a)

No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of the POTW, or pass through the POTW. The following general prohibitions shall apply to all users of the city POTW whether or not a user is subject to National Categorical Pretreatment Standards or any other national, state or local pretreatment standards or requirements. A user may not contribute the following substances to the city POTW.

(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 or hazardous in any other way to the POTW or to the operation of the POTW. At no time, shall two (2) successive readings on a meter capable of reading L.E.L. (lower explosive limit) at a point at the nearest accessible point to the POTW in a sanitary sewer, at the point of discharge into the POTW, or at any point in the POTW be more than five (5) percent nor any single reading greater than ten (10) percent. Materials in this subsection include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketone, aldehydes, peroxides, chlorates, perchlorates, bromates, polychlorinated biphenyls, polybrominated biphenyls, carbides, hydrides, stoddard solvents, and sulfides.

(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, 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, plastics, tar, asphalt residues from refining or processing of fuel or lubricating oil, mud or glass grinding or polishing wastes, or tumbling and de-burring stones.

(3)

Any wastewater which will cause corrosive structural damage to the POTW, but in no case wastewater having pH less than 5.0, unless more strictly limited elsewhere in this article.

(4)

Any wastewater containing incompatible 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 incompatible effect in the receiving water of the POTW, exceed the limitation set forth in a National Categorical Pretreatment Standard (when effective), or in section 22-136 of this article or create a public nuisance. An incompatible pollutant shall include, but not be limited to, any pollutant identified pursuant to Section 307(a) of the Act.

(5)

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

(6)

In no case shall a substance discharged to the POTW cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act; any criteria guidelines or regulations affecting sludge use or disposal developed pursuant to the RCRA, SWDA, the Clean Water Act, the Toxic Substances Control Act, or state criteria applicable to the sludge management method being used.

(7)

Any substance which will cause the POTW to violate its NPDES permit or the receiving water quality standards.

(8)

Any wastewater having a temperature at the point of discharge to the POTW which will inhibit biological activity in the POTW treatment plant resulting in interference; in no case shall wastewater be introduced to the POTW which exceeds 65°C (149°F) or which exceeds 40°C (104°F) at the POTW treatment plant.

(9)

Any pollutants, including compatible pollutants released at a flow or pollutant concentration which a user knows or has reason to know will cause interference to the POTW or will pass through the POTW. In no case shall a slug measured at the point of discharge to the POTW have a flow rate or contain concentrations of pollutants that exceed, more that five (5) times the average twenty-four-hour concentrations, or twenty-four-hour flow during normal operation; provided, however, that a user subject to National Categorical Pretreatment Standards shall comply with such standards in addition to this subsection (a)(9).

(10)

Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by state or federal regulations.

(11)

Any wastewater which may contain more than one hundred (100) mg/l concentration of fat, oil, grease (FOG) or freon extractable material.

(12)

Any wastewater containing BOD, total solids, or suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant; provided, however, that a user may be permitted by specific, written agreement with the city, which agreement to discharge such BOD or TSS may provide special charges, payments or provisions for treating and testing equipment.

(13)

Ammonia nitrogen in amounts that would cause the city to fail to comply with regulations of IEPA.

(14)

Mercury in amounts that would exceed the requirements of Section 304.126 of Title 35: Environmental Pollution, Subtitle C, Water Pollution, Chapter 1, Pollution Control Board, as amended.

(b)

No person shall discharge or cause to be discharged any waste without being in compliance with the provisions of the Pollution Discharge Control Ordinance of the City of Effingham, Ordinance No. 94-2004.
