Fox Metro Prohibitive Discharge Standards

(Ordinance #517, Section 300.105)

The following are narrative standards, most of which are required by federal regulation, but many of which would have been required by Fox Metro anyway.

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 Fox Metro wastewater treatment system or will pass through the wastewater treatment system.

In addition, the following pollutants shall not be introduced into the Fox Metro wastewater treatment system:

(1) Pollutants which create a fire or explosion hazard in the wastewater collection system, including, but not limited to:

(i) waste streams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade using the test methods specified in 40-CFR-261.21; or

(ii) at no time shall two (2) successive Lower Explosion Limit (LEL) readings of five percent (5%) nor any single reading of ten percent (10%) occur at any point in the wastewater treatment system.

(2) Any wastewater which will cause corrosive structural damage to the wastewater treatment system, but in no case wastewater having a pH less than 5.0 units, or any wastewater having a pH greater than 12.5 units which is not in accordance with the notification requirements of Section 300.165 of this Ordinance.

(3) 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 (1/2") 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 lubrication oil, mud, glass, grinding or polishing wastes, tumbling or deburring stones, or any material which can be disposed of as trash.

(4) Any wastewater containing pollutants, released at a flow or concentration, either singly or by interaction with other sources, to injure or cause interference with any wastewater treatment process, constitute a hazard to humans or animals, cause pass through resulting in a violation of the water quality standards of the receiving waters of the Fox Metro wastewater treatment system, exceed any limitation set forth in a National Categorical Pretreatment Standard (when effective) or in Section 300.120 of this Ordinance or create a public nuisance.

(5) Any wastewater having a temperature which will inhibit biological activity in the wastewater treatment plant resulting in Interference; in no case shall wastewater be discharged which causes temperatures at the head of the Fox Metro wastewater treatment plant to exceed 104 degrees Fahrenheit or 40 degrees Centigrade.

(6) Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin in amounts that will cause Interference or Pass Through.

(7) Any pollutant(s), which either singly or by interaction with other wastewater, result in the presence of toxic gases, vapors or fumes in the Fox Metro wastewater treatment system in a quantity that may cause acute worker health and safety problems to occur.

(8) Trucked or hauled pollutants, except at discharge points designated by Fox Metro in accordance with Section 300.180 of this Ordinance.

(9) 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.

(10) In no case shall a substance be discharged into the Fox Metro wastewater collection system which causes Fox Metro 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 Air Act, or State criteria applicable to the sludge management method being used.

(11) Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the latest State or Federal Regulations including Section 10-CFR-20 and Illinois Administrative Code Title 32: Chapter II: Subchapter b: Part 340. (Amended per Ordinance 659, November 20, 2002.)

The limit as established at the time Ordinance 659 was passed per 10-CFR-20, Appendix B is given by the following equation:

where:
CRA-226 = the concentration of Radium 226 in picocuries per liter.
CRA-228 = the concentration of Radium 228 in picocuries per liter.

(12) Any wastewater containing compatible pollutants 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 Fox Metro, which agreement to discharge such compatible pollutants may provide for special charges, payments or provisions for treating or testing equipment.

(13) Any discharge exceeding the standards established in 35-Ill. Adm. Code 307.

(14) Any slug discharged into the Fox Metro wastewater treatment system.

(15) Any regulated medical waste as defined by 40-CFR-259.30(a), or residues resultant from treatment and destruction processes of said waste, except as specifically authorized by the District Manager in a Discharge Permit.

(16) Any wastewater containing detergents, surface active agents, or other substances which may cause excessive foaming in the Fox Metro wastewater treatment system.
