A. 
General prohibitions. No user shall contribute or cause to be contributed into the POTW any pollutant or wastewater which causes pass through or interference with the operation or performance of the POTW. These general prohibitions apply to all users of the POTW, whether or not they are subject to National Categorical Pretreatment Standards or any other national, state, or local pretreatment standards or requirements.
B. 
Specific prohibitions. No user may contribute or cause to be contributed the following substances into the 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 a fire or explosion hazard or be injurious in any other way to the POTW or to the operation of the POTW, including, but not limited to, waste streams with a closed-cup flashpoint of less than 140° F. (60° C.) using the test methods specified in 40 CFR 261.21. At no time shall two successive readings on any explosion hazard meter at the point of discharge into the system (or at any point in the system) be more than 5% nor any single reading be over 10% of the lower explosive limit (LEL) of the meter.
(a) 
Prohibited materials include but are not limited to gasoline, fuel oil, kerosene, naphtha, benzene, toluene, xylene, paint products, ethers, alcohols, ketones, aldehydes, peroxides, acids or bases, chlorates, perchlorates, bromates, carbides, hydrides and sulfides and any other substances which the Borough, the state or EPA has notified the user is a fire hazard or a hazard to the system.
(2) 
Having a pH, stabilized, lower than 6.0 or higher than 9.0 or having any other corrosive or scale forming a property capable of causing damage to structures, equipment, bacterial action or personnel of the POTW.
(3) 
Solid or viscous substances in amounts which will cause obstruction of the flow in the POTW resulting in interference but in no case solids greater than 1/2 inch or 1.27 centimeter(s) in any dimension.
(a) 
Prohibited materials include, but are not limited to garbage, offal, ashes, cinders, spent lime, stone dust, sand, mud, straw, shavings, metals, glass, straw, shavings, rags, grass clippings, feathers, tar, plastics, wood, whole blood, paunch manure, bentonite, lye, building materials, rubber, asphalt residues, hair, bones, leather, porcelain, china, ceramic wastes, polishing wastes, glass grinding, residues from refining or processing of fuel or lubricating oil, or other solid or viscous substances capable of causing obstruction or other interference with the operation of the POTW.
(4) 
Pollutants, including oxygen-demanding pollutants (BOD5, etc.), released in a discharge at a flow rate and/or pollutant concentration which, either singly or by interaction with other pollutants, will cause interference with the POTW.
(a) 
In no case shall a wasteload have a flow rate or contain concentrations or qualities of pollutants that exceed for any time period longer than 15 minutes, more than five times the average twenty-four-hour concentration, quantities, or flow during normal operation, unless otherwise authorized in writing by the Pretreatment Officer.
(5) 
Any wastewater having a temperature which will inhibit biological activity in the Borough's treatment plant resulting in interference, but in no case wastewater which causes the temperature at the introduction into the POTW to exceed 104° F. (40° C.) or is less than 32° F. (00° C.).
(6) 
Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through.
(7) 
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, included but not limited to human life or public nuisance.
(8) 
Trucked or hauled pollutants, except at discharge points designated by the Borough of Hanover in accordance with § 290-16 of this part.
(9) 
Any noxious or malodorous liquids, gases, solids, or other wastewater which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or a hazard to life, or to prevent entry into the sewers for maintenance or repair.
(10) 
Any wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the treatment plant's effluent, thereby violating the Borough's NPDES permit.
(11) 
Color (in combination with turbidity) shall not cause the treatment plant effluent to reduce the depth of the compensation point for photosynthetic activity by more than 10% from the seasonably established norm for aquatic life.
(12) 
Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration except in compliance with applicable state or federal regulations.
(13) 
Stormwater, surface water, groundwater, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, noncontact cooling water, and unpolluted industrial or nonresidential process water, unless specifically authorized in writing by the Pretreatment Officer.
(a) 
The discharge of cooling water from air conditioning units with cooling towers or recirculating systems is prohibited. The sanitary sewers are not designed to handle the cooling water volumes produced by air conditioning units. Cooling water, free from bacteria and harmful chemicals, should be drained into storm sewers in accordance with state and federal requirements. Should discharge not be approved by state and federal authorities written approval from the Pretreatment Officer must be obtained for discharge to POTW.
(14) 
Any residue, including biosolids, chemical sludges or screenings from the pretreatment of industrial wastes.
(15) 
Any medical wastes, except as specifically authorized by the Pretreatment Officer in a wastewater discharge permit, general permit or written authorization.
(16) 
Any wastewater containing pollutants in sufficient quantity which, either singly or by interaction with other pollutants may create a toxic effect in the receiving waters of the POTW, cause the plant effluent to fail a toxicity test, or exceeds the limitations set forth in a National Categorical Pretreatment Standard. A toxic pollutant shall include, but not limited to, any pollutant identified pursuant to Section 307(a) of the Act.
(17) 
Any detergents, surface-active agents, or other substances in sufficient quantities which causes excessive foaming in the POTW;
(18) 
Any substance which may cause the POTW's effluent or any other product of the POTW, such as residues, sludges, or scums, to be unsuitable for reclamation or reuse, or to interfere with the reclamation process. 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; or any criteria, guidelines, or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substance Control Act, or state criteria applicable to the sludge management method being used.
(19) 
Fats, oils, or greases of animal or vegetable origin in concentrations greater than 60 mg/l;
(20) 
Containing BOD or suspended solids concentration of such character and quantity that unusual attention or expense is required to handle such materials in the POTW. Discharges in excess of 300 mg/l shall be subject to surcharge as provided for in the Borough of Hanover Sewer Use Ordinance.[1] Discharges in excess of 1,000 mg/l shall be subject to a penalty surcharge as provided for in the Borough's Sewer Use Ordinance. Discharge limitations, for nondomestic users, for BOD and total suspended solids shall be developed and issued into an industrial wastewater discharge permit, on a case by a case basis.
[1]
Editor's Note: See Ch. 286, Sewers and Sewage Disposal.
(21) 
Containing total solids greater than 2,000 mg/l or of such character and quantity that unusual attention or expense is required to handle such materials at the POTW.
(22) 
Having a chlorine demand in excess of 12 mg/l at a detention time of 20 minutes.
(23) 
Any substance and/or discharge not listed above which will cause the POTW to violate its NPDES and/or state permit or the receiving water quality standards.
(24) 
Any substance prohibited by any permit issued by, but not limited to, the Commonwealth of Pennsylvania or the Environmental Protection Agency.
C. 
Pollutants, substances, or wastewater prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the POTW.
D. 
All floor drains located in process or materials storage areas must discharge to the industrial user's pretreatment facility before connecting to the POTW.
E. 
If such amounts of any waters or wastes are discharged to the sewer system, which waters contain the substance or possess the characteristics enumerated in this section or which in the judgement of the Borough may have a deleterious effect upon the sewer system or receiving waters, the Borough may, upon giving notice to the discharger:
(1) 
Reject the waste.
(2) 
Require pretreatment to reduce characteristics to maximum limits permitted by this part or any other applicable rules or law.
(3) 
Require control over the quantities and rates of discharge.
(4) 
Require immediate discontinuance of the waste discharge until such time as it meets the requirements of this section.
F. 
The use of mechanical garbage grinders producing a finely divided mass, properly divided mass, properly flushed with an ample amount of water, shall be permitted upon the condition that no such mechanical garbage grinder to serve premises used for commercial purposes shall be installed until permission for such installation shall have been obtained from the Borough.
G. 
Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense, and shall be accessible to the Borough for inspection and testing.
The National Categorical Pretreatment Standards found at 40 CFR Chapter 1, Subchapter N, § 405 to 471 are hereby incorporated into this part. Upon promulgation of a National Categorical Pretreatment Standard under Section 307 of the Clean Air Act for a particular industrial subcategory, the pretreatment standard, if more stringent than limitations imposed under this part for sources in that subcategory, shall supersede the limitations imposed by the Borough. All affected significant industrial users must comply with the applicable reporting requirements under 40 CFR § 403.12(b).
A. 
EPA regulations at 40 CFR § 403.13 authorize a CIU to obtain a variance from a categorical pretreatment standard if the CIU can prove, pursuant to the procedural and substantive provisions in 40 CFR § 403.13, that factors relating to its discharge are fundamentally different from the factors considered by EPA when developing the categorical pretreatment standard. The POTW will recognize revised standards if the CIU has obtained an FDF variance from EPA on the bases of 40 CFR § 403.13.
B. 
When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the Borough may impose an alternate limit using the combined waste stream formula in 40 CFR § 403.6(e).
State requirements and limitations on discharges apply in any case where they are more stringent than national pretreatment standards or requirements, or those in this part.
A. 
The Borough is authorized to establish local limits pursuant to 40 CFR 403.5(c) and, but not limited to, the POTW NPDES permit. The local limits will follow the procedure as outlined in 40 CFR 403.5(c)(3) and made part of this part. Specific limitations will require acceptance by EPA. Local limits may be detailed in a user's wastewater discharge Permit, issued pursuant to § 290-19 of this part.
B. 
The following pollutant limits are established to protect against pass through and interference.
(1) 
No person shall discharge wastewater containing in excess of the following daily maximum limit.

C. 
The Borough may develop best management practices (BMPs), by ordinance or in a wastewater discharge permit, to implement the conditions of this part. Such BMPs shall be considered local limits and pretreatment standards for the purposes of the Act.
The Borough reserves the right to establish through a wastewater discharge permit more stringent limitations or requirements on discharges to the POTW if deemed necessary and appropriate to comply with the objectives presented in this part.
No user shall ever increase the use of process water, or in any way attempt to dilute a discharge, as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the National Categorical Pretreatment Standards, or with any other pretreatment standard or requirement.
No user shall knowingly make any false statements, representations, or certifications in any application, record, report, plan, or other document filed or required to be maintained pursuant to this part or to a wastewater discharge permit, or falsify, tamper with, or knowingly render inaccurate any monitoring device or method required under this part.
