Sewer Use Rules and Regulations - September 2003

Section 6.01: General Discharge Prohibitions

No User shall introduce, cause to be introduced, or permit to be introduced, directly or indirectly, into the POTW any pollutant or wastewater which will interfere with or adversely affect the operation, maintenance or performance of the POTW, or pass through the POTW into the waters of the Commonwealth of Pennsylvania any such items which cause, alone or in conjunction with other discharges, a violation of any requirement of the Authority for the operation, maintenance or use of the Authority's POTW NPDES permit, or adversely impacts or affects the use or disposal of the POTW's water or sludge.

No User shall introduce, cause to be introduced, or permit to be introduced, directly or indirectly, any of the following substances into the POTW:

1. Ignitable Waste. A waste or substance which can create a fire hazard in the POTW which has any of but is not limited to the following properties:

a. It is a liquid with a flash point less than 60 degrees C (140 degrees F) using the test methods specified in 40 CFR 261.21.

b. It is an oxidizer as defined in 49 CFR 173.151.

2. Reactive/Explosive Waste. A waste or substance which can create an explosion hazard in the POTW which has any of but is not limited to the following properties:

a. It is normally unstable and readily undergoes violent change without detonating.

b. It reacts violently with water.

c. It forms potentially explosive mixtures with water.

d. When mixed with water, it generates toxic gases, vapors, or fumes in a quantity sufficient to present a danger to human health or the environment.

e. It is a cyanide or sulfide-bearing waste, which can generate toxic, gases, vapors, or fumes in a quantity sufficient to present a danger to human health or the environment.

f. It is capable of detonation or explosive reaction if it is subjected to a strong initiating source or if heated under confinement.

g. It is readily capable of detonation, explosive decomposition or reaction at standard temperature and pressure.

h. It is a forbidden explosive as defined in 49 CFR 173.51, or a Class A explosive defined in 49 CFR 173.53 or a Class B explosive as defined in 49 CFR 173.88.

3. Corrosive Waste. A waste or substance which has any of the following properties:

a. It is aqueous and has a pH less than or equal to 5 or greater than or equal to 10, as determined by a pH meter.

b. It is a liquid and corrodes steel (SAE 1020) at a rate greater than 6.35 mm (0.250 inch) per year at a test temperature of 55C (130F).

Hazardous Waste. All wastes that are defined as hazardous under the regulations enacted pursuant to the Resource Conservation and Recovery Act (RCRA) as specified in 40 CFR 261 or under the regulations promulgated pursuant to the Pennsylvania Solid Waste Management Act as specified in 25 PA Code 261, except as provided for in these regulations.

5. Thermal Waste. Any wastewater with a temperature greater than 60C (140OP). Also, heat in the amounts which will inhibit biological activity in the POTW resulting in interference, but in no case heat in such quantities that the temperature at the POTW treatment plant exceeds 27C (800P).

6. Radioactive Waste. Any waste which exceeds the naturally occurring background levels for either alpha, beta, or gamma radiation and/or any wastewater containing any radioactive wastes or isotopes of such half life or concentration not in compliance with applicable State or Federal regulations.

7. Solid or Viscous Substances. Any solid or viscous substances capable of causing obstruction to the flow in sewers or other interference with the proper operation of the Authority's facilities or facilities discharging into the Authority's system.

8. Malodorous/Noxious Substances. Any pollutants or noxious or malodorous liquids, gases, or solids which either singly or by interaction with other wastes:

a. result in the presence of toxic gases, vapors, or fumes in a quantity that may cause acute worker health and safety problems; or

b. are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for maintenance and repair .

9. Any pollutant, including oxygen-demanding pollutants (BOD, etc.) released in a discharge at a flow rate and/or pollutant concentration which will cause interference with the POTW .

10. Any substance which will cause the POTW's effluent or any other product of the POTW such as residues, sludge, or scum, to be unsuitable for reclamation processes, including any substance which will 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 promulgated pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act or State laws or regulations applicable to the treatment or disposal of such effluent or such product.

11. Petroleum oil, non-biodegradable cutting oil, or products of mineral oil in origin in amounts that will cause interference or pass through, notwithstanding the provisions of Section 6.04 of these regulations relating to oil and grease.

Section 6.02: National Categorical Pretreatment Standards

Certain Industrial Users are now or hereafter shall become subject to National Categorical Pretreatment Standards promulgated by the EP A specifying quantities or concentrations of pollutants or pollutant properties which may be discharged into the POTW .Each Industrial User subject to a National Categorical Pretreatment Standard shall comply with all requirements of such standard, and shall also comply with any additional or more stringent limitations contained in these regulations unless modified pursuant to these regulations. Compliance with National Categorical Pretreatment Standards for existing sources subject to such standards or for existing sources which hereafter become subject to such standards shall be within three (3) years following promulgation of such standards, unless a shorter compliance time is specified in the standard. Compliance with National Categorical Pretreatment Standards for new sources shall be upon promulgation of the standard. Compliance with National Categorical Pretreatment Standards is required whether or not the Industrial User has been issued a permit or that permit has been revised pursuant to these regulations. For the purpose of implementing and enforcing the provisions of this section, the National Categorical Standards, found in 40 CFR Chapter I, Subchapter N, parts 405-471, are hereby incorporated into these regulations and made apart hereof.

 

Section 6.03: Notice of National Categorical Pretreatment Standards and Other Requirements

 

Upon the promulgation of National Categorical Pretreatment Standards for a particular industrial subcategory, the Director shall notify all affected Users of such promulgation and of the applicable reporting requirements under 40 CFR 403.12. The Director shall also notify affected Users of any other applicable standards or requirements under sections 204(b) and 405 of the Act and subtitles C and D of the Resource Conservation and Recovery Act.

 

Section 6.04: Specific Pollutant Limits

 

No User shall discharge, cause to be introduced, or permit to be introduced, directly or indirectly, wastewater containing concentrations of pollutants in excess of those contained in the standards listed below unless (a) an exception has been granted to the User under the provisions of these regulations or (b) the wastewater permit issued to such User pursuant to these regulations provides, as a special permit condition, a higher interim concentration level in conjunction with a requirement that such User construct a pretreatment facility or institute changes in its operation and maintenance procedures to reduce the concentration of pollutants to levels not exceeding the standards set forth in the table within a fixed period of time. Interim limits shall be established in accordance with the requirements of these regulations.

The 121 specific pollutant limitations are divided into the following 5 classifications:
