No person shall discharge or cause to be discharged to any sanitary sewer any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water, unpolluted industrial process waters, or unpolluted water from hydraulically operated equipment.
A.
No polluted waters shall be discharged into the storm sewer.
B.
Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers, or to a natural outlet approved by the Director. Industrial cooling water or unpolluted process waters may be discharged, on approval of the Director, to a storm sewer or natural outlet. A discharge to a natural outlet may require a NPDES permit.
[Amended 4-17-2019 by Order No. FY 19-125]
All industries discharging into a public sewer shall perform, at no cost to the City, such monitoring of their discharges as the Director and/or other duly authorized employees of the City may reasonably require, including installation, use, and maintenance of sampling, monitoring and flow equipment, keeping records, and reporting the results of such monitoring to the Director. Such records shall be made available upon request by the Director to other agencies having jurisdiction over discharges to the receiving waters.
No user shall contribute or cause to contribute, directly or indirectly, any pollutant or wastewater which can harm the sewers, pass through the POTW, interfere with the operation or performance of the POTW, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property, or constitute a nuisance. These general prohibitions apply to all such users of the POTW, whether or not the user is subject to national categorical pretreatment standards or any other national, state, or local pretreatment standards or requirements. A user may not contribute the following substances to any 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. 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. Waste streams with a closed-cup flashpoint of less than 140° F. or 60° C. (using the test methods specified in 40 CFR 261.21) are also prohibited. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides, and sulfides.
B.
Any waters or wastes 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, create a toxic effect in the receiving waters of the POTW, or to exceed the limitation set forth in a categorical pretreatment standard. A toxic pollutant shall include but not be limited to any pollutant identified pursuant to Section 307(a) of the Act.
C.
Any waters or wastes having a pH less than 6.5 or greater than 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment, and/or personnel of the POTW.
D.
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 or tissues, paunch manure, bones, hair, hides or fleshing, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, hops and beans, wastepaper, wood, plastics, gas, tar, asphalt residues, residues from refining or processing of fuel or lubricating oil, mud, or glass grinding or polishing wastes.
E.
Any wastewater having a temperature higher than 60° F. (71° C.), or containing heat in 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 treatment plant exceeds 40° C. (104° F.).
F.
Any water or waste containing fats, wax, grease, or oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32° F. and 150° F.
G.
Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of 3/4 horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Director.
H.
Any waters or wastes containing strong acid, iron pickling wastes, or concentrated plating solutions, whether neutralized or not.
I.
Any wastes exerting an excessive chlorine demand.
J.

L.
Any wastewater containing any radioactive wastes or isotopes of such half life or concentration as may exceed limits established by the Director in compliance with applicable state or federal regulations.
M.
Materials which exert or cause:
(1)
Unusual concentrations of inert suspended solids (such as, but not limited to, fullers earth, lime slurries, and lime residues) or of dissolved solids (such as, but not limited to, sodium, chloride and sodium sulfate). TSS concentrations of discharge shall not exceed 250 lbs./day.
(2)
Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions).
(3)
Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to cause or result in inhibition, interference, or pass through at the POTW. BOD of discharge shall not exceed 250 lbs./day.

N.
Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or which will cause the POTW to violate its NPDES or the receiving water quality standards.
O.
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.
P.
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.
Q.

A.
If any waters or wastes are discharged, or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in § 355-21 of this article, and which in the judgment of the Director may have a deleterious effect upon the sewage works, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Director may:
B.
If the Director permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Director and subject to the requirements of all applicable codes, ordinances, and laws.
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.
[Amended 4-17-2019 by Order No. FY 19-125]
No statement contained in this article shall be construed as preventing any special agreement or arrangement between the City and any industrial user whereby an industrial waste of unusual strength or character may be accepted by the City for treatment, subject to payment therefor by the industrial user. No such agreement or arrangement shall violate any applicable pretreatment standards which includes categorical standards, prohibitions, and local limits. For clarity, it is noted that the TSS and BOD limits cited in Article IV, § 355-21M(1) and (3) are not defined as local limits, but operational limits.
The national categorical pretreatment standards, located in 40 CFR Chapter I, Subchapter N, Parts 405 through 471, are hereby incorporated into these regulations. Upon the promulgation of the federal categorical pretreatment standards for a particular industrial subcategory, the federal standard, if more stringent than limitations imposed under these regulations for sources in that subcategory, shall immediately supersede the limitations imposed under these regulations. All categorical industrial users are subject to the reporting requirements outlined in 40 CFR 403.12.
State requirements and limitations on discharges shall apply in any case where they are more stringent than federal requirements and limitations or those in these regulations.
[Amended 4-17-2019 by Order No. FY 19-125]
The City reserves the right to establish by regulation more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives presented in Article I of these regulations.
[Amended 4-17-2019 by Order No. FY 19-125]
No industrial 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 federal categorical pretreatment standards or in any other pollutant-specific limitation developed by the City or state.
[Amended 4-17-2019 by Order No. FY 19-125]
A.
Each industrial user shall provide protection from accidental discharge of prohibited materials or other substances regulated by these regulations. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner's or user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the City for review, and shall be approved by the City before construction of the facility. No industrial user who commences contribution to the POTW after the effective date of these regulations shall be permitted to introduce pollutants into the system until accidental discharge procedures have been approved by the City. Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify the user's facility as necessary to meet the requirements of these regulations. In the case of an accidental discharge, it is the responsibility of the user to immediately telephone and notify the Director of the incident. The notification shall include the location of the discharge, type of waste, concentration and volume, and corrective actions.
B.
Within five days following an accidental discharge, the industrial user shall submit to the Director 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 under Article IX or other applicable law.
C.
A notice shall be permanently posted on each industrial user's bulletin board or other prominent place advising employees whom to call in the event of a dangerous discharge. Employers shall ensure that all employees who may cause or suffer such a dangerous discharge to occur are advised of the emergency notification procedure.
All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this regulation shall be determined in accordance with the techniques prescribed in 40 CFR 136 and amendments, and shall be performed on processed water only unless directed otherwise by the Director. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb, and property. The particular analyses involved will determine whether a twenty-four-hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from twenty-four-hour composites of all outfalls, whereas pHs are determined from periodic grab samples.
[Amended 4-17-2019 by Order No. FY 19-125]
The discharge of hauled or trucked pollutants, except at points which the POTW designates, is prohibited. No septic tank contents shall be discharged into the public sewer system, except at the manhole at the water pollution control treatment plant so designated by the Director for such purpose. A fee set annually by the Director will be charged to all septage haulers. The fee will be based on vehicle capacity, whether full or not. In addition, any hauler disposing of septage at the plant must hold a valid "septic transport license" from the Board of Health. Only septic and grease interceptor tank contents from the City of Greenfield shall be allowed. The Director reserves the right to reject, suspend, or place a limit on the volume of material accepted at the water pollution control plant.
