Except as otherwise provided in this Part 9, no user shall discharge or cause to be discharged to the sewerage system any sewage, wastewater, industrial wastewater or other matter or substance:

A. Having a temperature which will inhibit biological activity at the DRWPCC resulting in interference, but in no case with a temperature at the introduction into the sewerage system which exceeds 120° F. or is less than 40° F. and in no case heat in such quantities that the temperature of the influent to the DRWPCC exceed 104° F.

B. Containing petroleum oils, nonbiodegradable cutting oils or other products of mineral oil origin, animal fats, oil, wax or grease or other similar substances (collectively called "oil and grease") in amounts that will cause pass-through or interference at DRWPCC or the Township collection system.

C. Containing any liquids, solids or gases at concentrations which are, or may be sufficient, either alone or by interaction with other substances, to cause fire or explosion or be injurious in any other way to the sewerage system or to the operation of the DRWPCC. Prohibited materials include, but are not limited to, gasoline, fuel oil, kerosene, naphtha, paint products, sulfides and any substance having a closed cup flashpoint of less than 140° F. using the test methods specified in 40 CFR 261.21.

D. Containing solid or viscous substances at concentrations which will cause obstruction to the flow in a sewer, pump station or other facility, or other interference such as, but not limited to, ashes, cinders, spent lime, stone dust, sand, mud, straw, shavings, metals, glass, rags, grass clippings, feathers, tar, plastics, wood, whole blood, paunch manure, bentonite, lye, building materials, rubber, asphalt residues, hairs, bones, leather, porcelain, china, ceramic wastes, polishing wastes or glass grindings. Sample that is collected over time, formed either by continuous sampling or by mixing discrete samples collected at regular intervals not exceeding one hour, during a twenty-four-hour time span. The sample may be composited either as a time composite sample (composed of discrete sample aliquots collected in one container at constant time intervals providing representative samples irrespective of discharge flow) or as a flow proportional composite sample

E. Having a pH, stabilized, lower than 5.0 or higher than 9.0, or having any other corrosive or scale forming property capable of causing damage or hazard to structures, equipment, bacterial action or personnel of the sewerage system.

F. Containing pollutants in sufficient quantity, either singly or by interaction with other pollutants, to injure, cause a pass-through or interference in the sewerage system, constitute a hazard to humans, animals or plants, create a toxic effect in the receiving waters of the DRWPCC or to exceed any limitation set forth in a National Categorical Pretreatment Standard.

G. Containing any noxious or malodorous liquids, gases or solids which, either singly or by interaction with other wastes are sufficient to create a public nuisance or result in toxic gases, vapors or fumes in the sewerage system in a quantity that will cause worker or public health and safety problems.

H. Containing objectionable color not removed in the treatment process such as, but not limited to, dye wastes and vegetable tanning solutions.

I. Containing radioactive substances of such half-life or concentration as may exceed limits which are prohibited by applicable state or federal regulations.

J. Prohibited by any permit, statute, rule, regulation and ordinance issued or promulgated by any public agency, including the state, EPA, Township and any municipality.

K. Containing any substance which will cause the DRWPCC to violate its NPDES permit or the receiving water quality standards or cause operating difficulties in the Township collection systems.

L. Containing any substance which shall cause the DRWPCC to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act or be in noncompliance with any criteria, guidelines or regulations affecting sludge use or disposal promulgated pursuant to the Solid Waste Control Act or State Clean Air Act, the Toxic Substances Control Act or state criteria applicable to the sludge management method being used.

M. Containing nonbiodegradable complex carbon compounds.

N. Constituting a slug load.

O. Containing stormwater or groundwater from pavements, areaways, roofs, foundation drains or any other sources.

P. Containing any garbage with particles greater than 1/2 inch in size.

Q. Containing pesticides, unless upon written request, special permission is obtained from the Township and DARA.

§ 253-79 Trucked or hauled wastewater.

B. Tank truck or hauled wastes may only be discharged at the DRWPCC upon the issuance of a discharge permit by DARA.

C. Tank truck or hauled wastes authorized for discharge shall be discharged only at the location, time and at a rate fixed by the discharge permit.

D. Tank truck or hauled waste discharges shall not include any industrial wastewater.

E. Prior to and during discharge, the tank truck or hauled waste shall be subject to inspection and sampling by DARA.

F. Tank truck or hauled waste discharges shall be subject to rates and charges in accordance with a schedule established by DARA, as amended from time to time.

§ 253-80 Strength of waste surcharge.

A. Any user discharging wastewater to the sewerage system defined as extra-strength wastewater in such resolutions as DARA shall adopt, from time to time, shall pay a surcharge as set forth in those resolutions. The effective date of any change in definitions or fees shall be stated in all such resolutions.

B. No user shall discharge into the sewerage system any extra-strength wastewater without a written permit from DARA providing for sampling and the payment of a surcharge to the Township, in accordance with the formulas set forth in the current DARA resolution.

C. The surcharge computations shall be based on the wastewater sample analyses for the most recent complete calendar quarter. Surcharges shall be based on wastewater sample analyses (or, in the absence thereof, on DARAs estimates) for the calendar quarter during which they apply. The surcharge formulas are independent of each other and measure different characteristics of the same wastewater. Surcharges measured by each formula are cumulative.

D. The surcharge billings shall be in addition to any other quarterly sewer use charge paid by the user to the Township. Payment of a surcharge shall not relieve the user of its obligation to comply with the mass loading limits listed in § 253-83 of this Part 9.
