(a) General Pollutant Prohibitions. No user shall discharge or cause to be discharged into the POTW, directly or indirectly, any pollutant or wastewater which will cause interference or pass through. These general discharge prohibitions shall apply to all users of the POTW whether or not the user is subject to national categorical pretreatment standards or to any other Federal, State, or local pretreatment standards or requirements. In addition, it shall be unlawful for a user to discharge into the POTW:
(1) Any liquid, solid or gas, which by reason of its nature or quantity, is sufficient either alone or by interaction with other substances to create a fire or explosion hazard or to be injurious in any other way to persons, to the POTW, or to the operations of the POTW. Pollutants, which create a fire or explosion hazard in a POTW, include, but are not limited to, wastestreams with a closed cup flash point of less than 140°F or 60°C using the test methods specified in 40 C.F.R. § 261.21; or
(2) Any solid or viscous substance in concentrations or quantities, which are sufficient to cause obstruction to the flow in a sewer or other encumbrances to the operation of the POTW, including, but not limited to, grease, animal guts or tissues, bones, hair, hides or fleshing, entrails, whole blood, feathers, ashes, cinders, sand, cement, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, strings, fibers, spent grains, spent hops, wastepaper, wood, plastic, tar, asphalt residues, residues from refining or processing of fuel or lubrication oil, mud or glass grinding or polishing wastes, or tumbling and deburring stones; or
(3) Any wastewater having a pH of less than 5.0 units or greater than 11.5 units; or
(4) Any wastewater containing petroleum oil, non-biodegradable cutting oil, products of mineral oil origin, or toxic pollutants in sufficient concentration or quantity either singly or by interaction with other pollutants to cause interference, or pass through, or constitute a hazard to humans or animals; or
(5) Any liquid, gas, solid or form of energy, which either singly or by interaction with other waste is sufficient to create toxic gas, vapor, or fume within the POTW in quantities that may cause acute worker health and safety problems, or may cause a public nuisance or hazard to life, or are sufficient to prevent entry into the sewers for their maintenance and repair; or
(6) Any substance which is sufficient to cause the POTW’s effluent or any other product of the POTW, such as residue, sludge, or scum to be unsuitable for reclamation processing where the POTW is pursuing a reuse and reclamation program. 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 33 U.S.C. § 1345, with any criteria, guidelines, or developed and promulgated regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Federal Clean Air Act, the Federal Toxic Substances Control Act, or with State criteria applicable to the sludge management method being used; or
(7) Any substance which will cause the POTW to violate either the consent judgment in U.S. EPA v. City of Detroit et al., Federal District Court for the Eastern District of Michigan Case No. 77-1100, or the City of Detroit’s National Pollutant Discharge Elimination System permit; or
(8) Any discharge having a color uncharacteristic of the wastewater being discharged; or
(9) Any wastewater having a temperature which will inhibit biological activity in the POTW treatment plant resulting in interference, but in no case wastewater with a temperature at the introduction into a public sewer which exceeds 150°F or which will cause the influent at the wastewater treatment plant to rise above 104°F (40°C); or
(10) Any pollutant discharge which constitutes a slug; or
(11) Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established in compliance with applicable Federal or State regulations; or
(12) Any floating fats, oil or grease which are sufficient to cause interference with or pass through the POTW; or
(13) Any solid materials having a specific gravity greater than 1.2 or a cross section dimension of ½ inch or greater which are sufficient to cause interference with the POTW.
(b) Specific Pollutant Prohibitions. No user shall discharge wastewater containing in excess of the following limitations:
(1) Compatible pollutants. See Appendix C.
(2) Non-compatible pollutants. No user shall discharge wastewater containing in excess of:
Arsenic (As) | 1.0 mg/l |
Cadmium (Cd) | See Appendix C |
Chromium (Cr) | 25.0 |
Copper (Cu) | 2.5 |
Cyanide (CN) (Available) | 1.0 |
Iron (Fe) | 1,000.0 |
Lead (Pb) | 1.0 |
Nickel (Ni) | 5.0 |
Silver (Ag) | 1.0 |
Zinc (Zn) | 7.3 |
Total Phenolic Compounds: | 1.0 |
or See Appendix B | |
All limitations are based on samples collected over an operating period representative of an industrial user’s discharge, and in accordance with 40 C.F.R. Part 136.
A. The limitation for total PCB is non-detect. Total PCB shall not be discharged at detectable levels, based upon U.S. EPA Method 608, and the quantification level shall not exceed 0.2 ugm/l, unless a higher level is appropriate because of demonstrated sample matrix interference. Where one or more samples indicate detectable levels of total PCB, the user shall be required to demonstrate compliance. For purposes of this section, this demonstration may be made using analytical data showing that the total PCB concentration is below the detection level, or submission of a BMP in accordance with Section 1042.13.
B. The limitation of mercury (Hg) is non-detect. Mercury (Hg) shall not be discharged at detectable levels, based upon U.S. EPA Method 245.1, and the quantification level shall not exceed 0.2 ugm/l, unless a higher level is appropriate because of demonstrated sample matrix interference. Where one or more samples indicate detectable levels of mercury, the user shall be required to demonstrate compliance. For the purposes of this section, this demonstration may be made using analytical data showing that the mercury concentration is below the detection level, or submission of a BMP in accordance with Section 1042.13(d).
All limitations are based on samples collected over an operating period representative of an industrial user’s discharge, and in accordance 40 C.F.R. Part 136.
(3) Compliance period. Within 30 days of the effective date of this ordinance, the Department shall notify all industrial users operating under an effective wastewater discharge permit of the requirement to submit a compliance report within 180 days after the effective date of this section. The compliance report shall demonstrate the user’s compliance or non-compliance with these limitations, and, in the event of non-compliance, include the submission of a plan and schedule for achieving compliance with the stated limitation. In no event shall a compliance schedule exceed 18 months from the effective date of this section. An industrial user who does not demonstrate compliance may petition the Department for a second extension as part of an administrative consent order. The Department shall include appropriate monitoring, reporting, and penalties into an administrative consent order that relates to a second extension, and shall enter into such an agreement only upon a good-faith showing by the industrial user of the actions taken to achieve compliance with this provision.
(c) National Categorical Pretreatment Standards. All users shall comply with the applicable national categorical pretreatment standards and requirements promulgated pursuant to the Act as set forth in 40 C.F.R. Subchapter N, Effluent Guidelines and Standards, which are hereby incorporated by reference, and with all other applicable standards and requirements, provided, that where a more stringent standard or requirement is applicable pursuant to State law or regulation, or to this chapter, then the more stringent standard or requirement shall be controlling. Affected dischargers shall comply with applicable reporting requirements under 40 C.F.R. Part 403 and as established by the Department. The national categorical pretreatment standards which have been promulgated as of the effective date of this section are delineated in Appendix A.
(1) Intake water adjustment. Industrial users seeking adjustment of national categorical pretreatment standards to reflect the presence of pollutants in their intake water must comply with the requirements of 40 C.F.R. § 403.15. Upon notification of approval by the Department, the adjustment shall be applied by modifying the permit accordingly. Intake water adjustments are not effective until incorporated into an industrial user’s permit.
(2) Modification of national categorical pretreatment standards. The Department may apply to the U.S. Environmental Protection Agency, or to the Michigan Department of Environmental Quality, whichever is appropriate, for authorization to grant removal credits in accordance with the requirements and procedures in 40 C.F.R. § 403.7. Such authorization may be granted only when the POTW treatment plant can achieve consistent removal for each pollutant for which a removal credit is being sought, provided, that any limitation of such pollutant(s) in the NPDES permit neither are being exceeded nor pose the prospect of being exceeded as a result of the removal credit being granted. Where such authorization is given to the Department, any industrial user desiring to obtain such credit shall make an application to the Department, consistent with the provisions of 40 C.F.R. § 403.7 and of this chapter. Any credits which may be granted under this section may be subject to modification or revocation as specified in 40 C.F.R. § 403.7, or as determined by the Department. A requisite to the granting of any removal credit may be that the industrial user pay a surcharge based upon the amounts of such pollutants removed by the POTW, such surcharge being based upon fees or rates which the Board may establish and, when appropriate, revise from time to time. Permits shall reflect, or be modified to reflect, any credit granted pursuant to this section.
(3) New sources. Industrial users who meet the new sources criteria shall install, maintain in operating condition, and “start-up” all pollution control equipment required to meet applicable pretreatment standards before beginning to discharge. Within the shortest feasible time and not to exceed 90 days, new sources must meet all applicable pretreatment standards.
(4) Concentration and mass limits. When limits in a categorical pretreatment standard are expressed only in terms of mass of pollutant per unit of production, the Department may convert the limits to equivalent limitations expressed either as mass of pollutant discharged per day or effluent concentration for purposes of calculating effluent limitations applicable to individual industrial users. Equivalent limitations shall be calculated in accordance with 40 C.F.R. § 403.6(c)(3) and/or 40 C.F.R. § 403.6(c)(4) and shall be deemed pretreatment standards for the purposes of 33 U.S.C. § 1317(d) and of this chapter. Industrial users will be required to comply with the equivalent limitations in lieu of the promulgated categorical standards from which the equivalent limitations were derived.
(5) Reporting requirements for industrial users upon effective date of categorical pretreatment standards-baseline report. Within 180 days after the effective date of a categorical pretreatment standard, or 180 days after the final administrative decision made upon a category determination submission under 40 C.F.R. § 403.6(a)(4), whichever is later, existing industrial users subject to such categorical pretreatment standards and currently discharging into or scheduled to discharge into the Detroit POTW shall submit to the Department a report containing the information listed in 40 C.F.R. § 403.12(b)(1)–(7). Where reports containing this information have already been submitted to the Director or Regional Administrator in compliance with the requirement of 40 C.F.R. § 128.140(b), the industrial user will not be required to resubmit this information. At least 90 days before commencement of any discharge, each new source and any existing sources that become industrial users after the promulgation of an applicable categorical pretreatment standard shall submit to the Department a report which contains the information listed in 40 C.F.R. § 403.12(b)(1)–(5). In such report, new sources shall include information concerning the method of pretreatment the source intends to use to meet applicable pretreatment standards. New sources shall provide estimates of the information requested in 40 C.F.R. § 403.12(b)(4) and (5).
(d) Dilution Prohibited. Except where expressly authorized to do so by an applicable pretreatment standard or requirement, no user shall increase the use of process water, or in any way dilute or 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 in any other pollutant specific limitation or requirement imposed by the City of Wayne, the City of Detroit or by the State of Michigan.
(e) Hauled in Wastewater. Any waste material or wastewater which is hauled into or within the service region for discharge to the POTW is subject to the requirements of this chapter including, but not limited to, permits, inspection, monitoring and enforcement. Unloading liquid or solid waste from hauling vehicles, directly or indirectly, into the POTW, with or without the benefit of pretreatment, is prohibited unless the person proposing to unload such waste has applied for and received a permit from the Department for unloading such waste in accordance with the Board’s rules pertaining thereto. The discharger shall be subject to applicable terms and conditions, surcharges, fees or rates as established by the Board. Hauled in wastewater shall only be discharged at points designated by the POTW after authorization or approval issued pursuant to the general permit requirements specified in Section 1042.08 of this Code. The Department may establish specific limitations for sludge from Municipally owned or operated POTW treatment plants which are different than the specific limitations in this chapter.
(f) Centralized Waste Treatment. It is unlawful for a centralized waste treatment (CWT) facility to discharge any industrial waste or wastewater into the POTW without a wastewater discharge permit from the Department. Any authorization granted, or permit issued, by the Department to a centralized waste treatment (CWT) facility shall specify the type of wastewater for which treatment is provided, and discharge approval is sought, from the POTW. Unless such industrial waste or wastewater is determined by the Department to require further authorization, a centralized waste treatment (CWT) facility that has submitted an application to, and received previous approval from, the Department to discharge wastewater is not required to obtain further authorization from the Department before discharging such wastewater. An industrial user, that provides centralized waste treatment services and files an application for the treatment and discharge of such types of wastewater to the POTW, shall provide the following minimum information in support thereof:
(1) The general nature, source and process(es) generating the type of wastewater. Any wastewater, which is generated from those processes and is subject to national categorical pretreatment standards as delineated in Appendix A, shall be so designated;
(2) The identity of the toxic pollutants known or suspected to be present in the wastewater;
(3) At least one sample report showing the results of an analysis for the EPA priority pollutants for each type of wastewater for which application is made in subsection (f)(1) of this section;
(4) A statement, that is certified by a professional engineer, which addresses the treatability and compatibility of the wastewater, received or collected by the facility’s treatment process(es);
(5) The identity of the materials and/or pollutants whose transport or treatment are regulated by the EPA, by the State, or by any other governmental agency. Upon request, the centralized waste treatment (CWT) facility shall provide a copy of its permit and/or license to the Department; and
(6) Other information requested by the Department including, but not limited to, information required by Section 1042.08(c)(1) through (18) of this Code, or by rules adopted by the Board. The discharge from a centralized waste treatment (CWT) facility will be deemed approved for those specific types of wastewater delineated in a permit and, upon issuance of such permit in accordance with the procedures contained in Section 1042.08 of this Code, will be deemed approved for discharge into the POTW. The centralized waste treatment (CWT) facility shall comply with all applicable provisions contained in Section 1042.08 of this Code regarding permits. In furtherance of its obligations as control authority, the Department may include in the permit a requirement to report at selected intervals the information mandated in subsections (1) through (6) of this section. All users granted a permit under this section shall maintain records which, at a minimum, identify the source, volume, character, and constituents of the wastewater accepted for treatment and disposal. These records may be reviewed at any time by the Department.
(g) Groundwater Discharges. Unless authorization has been granted by the Department, the discharge of any groundwater into the POTW is prohibited. The Department may authorize the discharge of groundwater resulting from maintenance and related activities of gas, steam, or electrical utilities through the use of general permits. Subject to appropriate reporting requirements, the general permit shall authorize discharge in accordance with the terms of the permit. Utilities shall comply with this provision within 180 days after its enactment. If a person, who proposes to discharge groundwater resulting from purge, response activity, or UST projects, has applied for and received a permit from the Department, the Department may authorize the discharge of such wastewater. Permits shall be issued in accordance with the procedures contained in Section 1042.08 of this Code, or in accordance with any rules adopted by the Board.
(h) City of Wayne Right of Revision. The City of Detroit and the City of Wayne reserve the right to establish rules or regulations adopted by the Board, additional or more stringent limitations or requirements on discharges to the POTW. These rules and regulations shall be adopted in accordance with the rule-making procedures section 2-111 of the 1997 Detroit City Charter, 90 days after adoption by the Board, industrial users shall comply with such rules and regulations.
(i) Accidental Discharges.
(1) Each industrial user, which does not currently have an approved spill prevention plan or slug control plan, shall provide protection from accidental discharge of prohibited materials or other substances regulated by this chapter, and all significant industrial users shall submit to the Department detailed plans which show facilities and operating procedures to be implemented to provide protection against such accidental discharges. Facilities and measures to prevent and abate accidental discharges shall be implemented, provided, and maintained at the owner’s or industrial user’s cost or expense. Unless the significant industrial user has an approved spill prevention or slug control plan, all existing significant industrial users shall complete and submit such a plan within 60 days of the original effective date of this chapter [November 19, 1986]. New significant industrial users shall submit such a plan prior to the time they commence discharging.
For purposes of this section, the information provided shall include the approximate average and maximum quantities of such prohibited materials or substances kept on the premises in the form of raw materials, chemicals and/or waste therefrom and the containment capacity for each. Only substances that are in a form which could readily be carried into the POTW and constitute a concentration of five percent or greater in the raw material, chemical solution or waste material, are required to be reported. Volumes of less than 55 gallons, or the equivalent thereof, need not be reported unless lesser quantities could cause pass through or cause interference with the POTW. The industrial user shall promptly notify the Department of any significant changes or modifications to the plan including, but not limited to, a change in the contact person, or substance inventory.
(2) At least once every two years, the Department shall evaluate whether a significant industrial user needs a plan to control slug discharges, as defined by 40 C.F.R. § 403.8(f)(2)(v). Unless otherwise provided, all significant users shall complete, implement, and submit such a plan within 30 days of notification by the Department.
(j) Notification Requirements. Unless a different notice is provided by this chapter or applicable law, within one hour of becoming aware of a discharge into the POTW which exceeds or does not conform with Federal, State or City of Wayne laws, rules, regulations or permit requirements, or which could cause problems to the POTW, or which has the potential to cause the industrial user to implement its plan prepared in accordance with subsection (1) of this section, the industrial user shall telephone the Department at its control center and notify the Department of the discharge. The notification shall include the name of the caller, the location and time of discharge, the type of wastewater, the estimated concentration of excessive or prohibited pollutants and estimated volume, and the measures taken, or being taken, to abate the discharge into the POTW. Within five calendar days after the discharge, the industrial user shall submit a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences and when required by the Department, the industrial user’s wastewater discharge permit may be modified to include additional measures to prevent such future occurrences. Such notification shall not relieve the industrial user of any expense, cost of treatment, loss, damages or other liability which may be incurred as a result of damage to the POTW, fish kills, or any other environmental impairment or any other damage to person or property.
(k) Notice to Employees. A notice shall be permanently posted on the industrial user’s bulletin board, or other prominent place, advising employees whom to contact in the Department in the event of an actual or excessive or prohibited discharge.
(l) Recovery of Costs. Any user discharging in violation of any of the provisions of this chapter, which produces a deposit or obstruction, or causes damage to or impairs the Department’s POTW, or causes the Department to violate its NPDES permit, shall be liable to the Department for any expense, loss, damage, penalty or fine incurred by the Department because of said violation or discharge. Prior to assessing such costs, the Department shall notify the user of its determination that the user’s discharge was the proximate cause of such damage, obstruction, impairment, or violation of the City’s NPDES permit and the Department’s intent to assess such costs to the user. Any such notice shall include written documentation which substantiates the determination of proximate cause and a breakdown of cost estimates. Failure to pay the assessed costs shall constitute a violation of this chapter. Such charge shall be in addition to, and not in lieu of, any penalties or remedies provided under this chapter, or this Code, or other statutes and regulations, or at law or in equity.
(m) Hazardous Waste Notification. All industrial users, who discharge into the City of Wayne Collection System, shall notify the Department in writing of any discharge of a substance which, if otherwise disposed of, would be a hazardous waste as set forth in 40 C.F.R. Part 261. Such notification must comply with the requirements of 40 C.F.R. § 403.12(p).
(1) The authorization is made in writing by the individual defined in Section 1042.03(a)(2)A. or B.;
(2) The authorization specifies either an individual or a position having responsibility for the overall operation of the facility where the industrial discharge originates, such as the position of plant manager, operator of a well or well field superintendent, or a position of equivalent responsibility, or having overall responsibility for environmental matters for the company; and
(3) The written authorization is submitted to the Department.
(o) Pollution Prevention. The Department shall encourage and support industrial users to develop and implement pollution prevention programs that are designed to eliminate or reduce pollutant contributions beyond the levels required by this chapter. The Department may require an industrial user to implement pollution prevention initiatives or BMP, as part of an enforcement response, or as necessary to comply with its NPDES permit.
