No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which will cause pass-through or interference with the operation or performance of the POTW. These general prohibitions apply to all such users of a POTW whether or not the user is subject to categorical pretreatment standards or any other national, state, or local pretreatment standards or requirements. A user shall not contribute the following substances to the POTW:
A. 
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 in any other way to the POTW or to the operation of the POTW. At no time shall two successive readings on an 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 over 10% of the lower explosive limit (LEL) of the meter. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromides, carbides, hydrides, and sulfides. Waste streams with a closed-cup flash point of less than 140° F. or 60° C. using the test methods specified in 40 CFR 261.21 are also prohibited.
B. 
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 1/2 inch in any dimension, animal guts, animal tissues or wastes, 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, residues from glass grinding or polishing wastes.
C. 
Any wastewater having a pH less than 5.5 s.u. or more than 9.0 s.u. or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment, and/or personnel of the POTW.
D. 
Any wastewater:
(1) 
Containing toxic 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, pass-through the POTW and degrade the receiving stream; or
(2) 
Containing substances in amounts that exceed any limitations set forth in a categorical pretreatment standard or any limitation in Article II of this chapter.
E. 
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 hazard to life or are sufficient to prevent entry into the sewers for maintenance and repair.
F. 
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 and 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; any criteria, guidelines, or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act, or state criteria applicable to the sludge management method being used.
G. 
Any substance which will cause the POTW to violate its NPDES and/or Pennsylvania DEP Stream Discharge Permit or cause a violation of the water quality standards of the receiving stream.
H. 
Any wastewater with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions.
I. 
Any wastewater as it enters the Authority's sewer with a temperature greater than 50° C. (122° F.); or, when in combination with other wastewaters, will increase the temperature of the influent to the POTW treatment plant above 40° C. (104° F.); or which heat will inhibit biological activity in the POTW resulting in interference.
J. 
Any pollutants, including oxygen-demanding pollutants (BOD etc.) released at a flow rate and/or pollutant concentration which will cause interference to the POTW. In no case shall a slug load have a flow rate five times the average operating flow rate nor contain concentrations or quantities of pollutants that exceed at any moment in time four times the average operating values.
K. 
Any wastewater containing any radioactive wastes or isotopes.
L. 
Any wastewater which causes a hazard to human life or creates a public nuisance.

P. 
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.
A. 
Clean water discharges into the POTW unnecessarily consume sewer and treatment plant capacities as well as reduce the effectiveness of the wastewater treatment processes and, therefore, the discharge of clean water is unacceptable to the Authority.
B. 
Specifically, no person shall discharge or cause to be discharged any unpolluted waters such as water from sump pumps, floor drains, stormwater, groundwater, roof runoff, subsurface drainage, foundation drainage, or cooling water into the POTW. Stormwater and all other unpolluted drainage shall be discharged to such sewers that are specifically designed as storm sewer or to a natural outlet. Industrial cooling water or unpolluted process waters may be discharged to a storm sewer or natural outlet upon the issuance of a permit to do so from the U.S. EPA or the Pennsylvania Department of Environmental Protection.
A. 
Upon the promulgation of the categorical pretreatment standards for a particular industrial subcategory, the national standard (located in 40 CPR Chapter 1, Sub-chapter N, Parts 405-471), if more stringent than limitations imposed under this chapter for sources in the subcategory, shall immediately supersede the limitations imposed under this chapter and shall be incorporated herein by reference. The Authority Manager shall notify all affected users of the applicable reporting requirements under 40 CFR, Section 403.12.
B. 
The Authority may also require, if deemed necessary by the Authority Manager, that the pollutants discharged by the user be segregated from sanitary sewage. This will require the installation of a separate drainage system sewer line exclusively for such pollutants and that system shall remain segregated until passage through a sampling and/or monitoring facility, at which time it may join the building's sanitary drain for continuation and connection to the Authority's sewer lateral.
A. 
The following limits of concentration are given for guidance to all existing and proposed users to the POTW. The tabulation represents the maximum permissible concentration of each specific parameter acceptable in a discharge when averaged over any twenty-four-hour operating period. The acceptable peak concentration of any substance at any given moment shall not exceed the concentration limits listed herein. Lower concentrations may be required of a pollutant if, in the judgment of the Authority, it is necessary to do so in order to protect the POTW processes, its sludge quality, and its effluent quality.
B. 
The Authority may take, at its sole discretion, materials that are generally considered compatible with the sewage treatment plant and its processes; that is, materials that are commonly associated with domestic waste, at concentrations greater than those listed under the daily maximum limit. However, a surcharge will be applied for the treatment and/or handling of the unusually strong pollutants in accordance with the formula and rate schedule on file at the Administration Office of the Warminster Township Municipal Authority. Pollutants having all characteristics at or below the twenty-four-hour limits will not be subject to a surcharge.
C. 
Pollutants having any characteristic beyond any limit value, as shown in the following table, shall be rejected.
D. 
Extra strong pollutants, with surcharge, shall be applicable to BOD, COD, total dissolved solids, total suspended solids, phosphates, chlorides, sulfates, ammonia nitrogen, nitrate nitrogen, organic nitrogen, iron, aluminum, and oil and grease. Additional and more specific limitations may be contained within the user's wastewater discharge permit, which shall be binding control values.
E. 
The following list is subject to additions and modifications as required of the Authority by regulatory agencies or as technical revelations may dictate to the Authority that it is prudent to revise the values tabulated. As tens of thousands of various pollutants exist, the list is not a tabulation of all substances that are or may be restricted by the Authority.

State requirements and limitations on discharges shall apply in any case where they are more stringent than federal requirements and limitations or those in this chapter.
The Township reserves the right to establish by ordinance more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives presented in § 105-1 of this chapter.
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 waste treatment or waste control to achieve compliance with the limitations contained in this chapter or in any categorical pretreatment standard, or in any other pollutant-specific limitation developed by the Township or state.
A. 
The user shall provide protection from accidental discharge to the sewer of prohibited or controlled materials or other substances regulated by this chapter. In the application for a wastewater discharge permit, the applicant shall provide a narrative detailing what facilities and/or operating procedures are, or shall be, employed to preclude an accidental discharge. The issuance of a wastewater discharge permit shall be contingent upon the submission of an acceptable spill control plan.
B. 
In case of an accidental discharge, the user shall immediately telephone and notify the Authority of the incident. During normal working hours, the user shall notify the Authority Manager, or his assistant at 215-675-3301 and during non-office hours notify the Chief Operator at the sewage treatment plant, telephone number 215-675-6113.
C. 
When requested by the Authority, a user shall develop a slug control plan which outlines discharge practices (including non-routine batch discharges), describes stored chemicals and which contains procedures both to notify the POTW immediately of slug discharges or if any changes at its facility affecting the potential for a slug discharge and to prevent, adverse impacts from accidental spills. The plan must be posted within the building in such a manner that all employees can see the plan. Furthermore, the plan must list the following information:
(1) 
Names and telephone numbers of people to be contacted within the company;
(2) 
Names and addresses of people outside the company who may need to be contacted;
(3) 
All emergency equipment on hand, the location of such emergency equipment and the names and telephone numbers of people who can handle such emergency equipment;
(4) 
Procedures to follow in case of a chemical spill; and
(5) 
The location of the material safety data sheets (SDS) which must be on site for all chemicals and products used in the company's business.
D. 
Written notice. Within five days following an accidental discharge, the user shall submit to the Authority Manager a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW, fish kills, or any other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties, or other liability which may be imposed by this article or other applicable law.
E. 
Notice to employees. A notice shall be permanently posted on the user's bulletin board or at the place of operations or other prominent place, advising employees whom to call in the event of a dangerous discharge. Employers shall ensure that all employees who are aware of or may cause such a dangerous discharge to occur are advised of the emergency notification procedures.
