[HISTORY: Adopted by the City Council of the City of Rockwood 1-21-1999 by Ord. No. 373. Amendments noted where applicable.]
This chapter sets forth uniform requirements for direct and indirect contributors into the wastewater collection and treatment system for the City and enables the City to comply with all applicable requirements of the Clean Water Act, the Michigan Natural Resources and Environmental Protection Act ("MNREPA"), the General Pretreatment Regulations (40 CFR, Part 403), and other regulations promulgated under applicable law, as amended.
The objectives of this chapter are to:
Prevent the introduction of pollutants into the municipal wastewater system, which pollutants will interfere with the operation of the system or contaminate the resulting sludge;
Prevent the introduction of pollutants into the municipal wastewater system, which pollutants will pass through the system, inadequately treated, into receiving waters or the atmosphere or otherwise be incompatible with the system;
Improve the opportunity to recycle and reclaim wastewaters and sludges from the system;
Provide for equitable distribution of the cost of the municipal wastewater system; and
Enable the City to comply with its National Pollutant Discharge Elimination System permit conditions, sludge use and disposal requirements, and any other federal or state laws to which the wastewater collection and treatment system is subject.
This chapter provides for the regulation of direct and indirect contributors to the municipal wastewater system through the issuance of permits to certain nondomestic users and through the enforcement of general requirements for the other users, authorizes monitoring and enforcement activities, requires user reporting, assumes that an existing customer's capacity will not be preempted and provides for the setting of fees for the equitable distribution of costs resulting from the program established in this chapter.

The local discharge limitation for mercury is established at the level of detection (LOD) in accordance with the following:
There shall be no detectable amounts of mercury discharged into the publicly owned treatment works (POTW). Mercury sampling procedures, preservation and handling, and analytical protocol for compliance monitoring shall be in accordance with EPA Method 245.1. The LOD, developed in accordance with the procedure specified in 40 CFR 136, shall not exceed 0.2 ug/L for mercury, unless higher levels are appropriate due to matrix interference.
The evaluation of potential matrix interference(s) shall include, at a minimum, the following:
In cases where true matrix interference(s) can be demonstrated, a discharge-specific LOD will be developed in accordance with the procedure in 40 CFR 136. Discharge-specific LODs will be incorporated into the wastewater discharge permit of the nondomestic user.
State requirements an limitations on discharges shall apply in any case where they are more stringent than federal requirements and limitations or those set forth in this chapter.
The City reserves the right to establish, by ordinance or in a wastewater discharge permit, more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives set forth in § 115-1.
No user shall 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 the state.
Additional pretreatment measures.
Whenever deemed necessary, the Superintendent may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage waste streams from industrial waste streams, and such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this chapter.
The Superintendent may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
Grease, oil and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil or sand, except that such interceptors shall not be required for residential users. All interception units shall be of a type and capacity approved by the Superintendent and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the user at his or her expense.
Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
Each user shall provide protection from an accidental discharge of prohibited materials or other substances regulated by this chapter. Facilities to prevent an accidental discharge or 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. All existing users shall complete such a plan by January 1, 1985. No user who commences contribution to the POTW after the effective date of this chapter 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 this chapter. In the case of an accidental discharge, the user shall immediately telephone and notify the POTW of the incident. The notification shall include the location of the discharge, the type of waste, the concentration and volume and corrective actions.
Within five days following an accidental discharge, the user shall submit to the Superintendent 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 any person or property, nor shall such notification relieve the user of any fine, civil penalty or other liability which may be imposed by this chapter or other applicable law.
A notice shall be permanently posted on the 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 procedures.
The City shall require an approved spill prevention program to be in place for all applicable users prior to the issuance of a sewer use permit.
The purpose of this section is to provide for the recovery of costs from users of the City's wastewater disposal system for the implementation of the program established in this chapter. The applicable charges or fees shall be set forth in the City's schedule of charges and fees.
The city's fee schedule stall include:

Requirements for maintaining and retaining plant records relating to wastewater discharge as specified by the City, and affording the City access thereto;
Requirements for notification of the City of any new introduction of wastewater constituents or any substantial change in the volume or character of the wastewater constituents being introduced into the wastewater treatment system.
At lest once every two years, the POTW may request that each significant industrial user provide a plan to control slug discharges. The results of such activities shall be available to the approval authority upon request. If the treatment plant decides that a slug control plan is needed, the plan shall contain, at a minimum, the following elements:
Description of discharge practices, including nonroutine batch discharges;
Description of stored chemicals;
Procedures for immediately notifying the treatment plant of slug discharges, including any discharge that would violate a prohibition under 40 CFR 403.5(b), with procedures for follow-up written notification within five days; and
If necessary, procedures to prevent adverse impact from accidental spills, including inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents), and/or measures and equipment for emergency response.
Other conditions as deemed appropriate by the City to ensure compliance with this chapter.
Wastewater analysis. When requested by the Superintendent, a user must submit information on the nature and characteristics of its wastewater within 10 days of the request. The Superintendent is authorized to prepare a form for this purpose and may periodically require users to update this information.
Duration. Permits shall be issued for a specified time period, not to exceed five years. A permit may be issued for a period less than a year or may be stated to expire on a specific date.
The Superintendent may modify a wastewater discharge permit for good cause, including, but not limited to, the following reasons:
To incorporate any new or revised federal, state, or local pretreatment standards of requirements;
To address significant alterations or additions to the user's operation, processes, or wastewater volume or character since the time of wastewater discharge permit issuance;
A change in the POTW that requires either a temporary or permanent reduction or elimination of the authorized discharge;
Information indicating that the permitted discharge poses a threat to the city's POTW, personnel, or the receiving waters;
Violation of any terms or conditions of the wastewater discharge permit;
Misrepresentations or failure to fully disclose all relevant facts in the wastewater discharge permit application or in any required reporting;
Revision of or a grant of variance from categorical pretreatment standards pursuant to 40 CFR 403.13;
To correct typographical or other errors in the wastewater discharge permit;
To reflect a transfer of the facility ownership or operation to a new owner or operator; or
Upon request of the permittee, provided that such request does not create a violation of any applicable requirements, standards, laws, or rules and regulations, or requirements of this chapter.
The user shall be informed of any proposed changes in his or her permit at least 30 days prior to the effective date of the charge. Any change or new condition in the permit shall include a reasonable time schedule for compliance.
Reissuance. The user shall apply for permit reissuance a minimum of 180 days prior to the expiration of the user's existing permit, or some lesser time as designated by the city. The application for reissuance shall include a written request for reissuance of the permit and a description of any circumstances that have changed since the current permit was issued or last modified, as well as any additional information requested by the city.
Permit transfer. Wastewater discharge permits may be transferred to a new owner or operator only if the permittee gives at least 30 days' advance notice to the Superintendent and the Superintendent approves the wastewater discharger permit transfer.
The notice to the Superintendent must include a written certification by the new owner or operator which:
Failure to provide advance notice of a transfer renders the wastewater discharge permit void as of the date of facility transfer.
Compliance date reports. Within 90 days following the date for final compliance with applicable categorical pretreatment standards or in the case of a new source following commencement of the introduction of wastewater into the POTW, any industrial user subject to pretreatment standards and requirements shall submit to the control authority a report containing the information described in Paragraphs (b)(4)-(6) of Section 40 CFR 403.12. For industrial users subject to equivalent mass or concentration limits established by the control authority in accordance with the procedures in 40 CFR 403.6(c), this report shall contain a reasonable measure of the user's long-term production rate. For all other industrial users subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the user's actual production during the appropriate sampling period.
Certification. A statement, reviewed by an authorized representative of the industrial user and certified to by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance and/or additional pretreatment is required for the industrial user to meet the pretreatment standards and requirements.
Reports. All wastewater discharge permit applications and user reports must be signed by an authorized representative of the user and contain the following certification statement:
|I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system design to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.|
If an authorization is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, or overall responsibility for environmental matters for the company, a new authorization must be submitted to the control authority prior to or together with any reports to be signed by an authorized representative.
Notice of change in discharge. All industrial users shall promptly notify the POTW in advance of any substantial changes in the volume or character of pollutants in their discharge, including the listed or characteristic hazardous wastes for which the industrial user has submitted initial notification under 40 CFR 403.12(p).
The City shall require to be provided and operated, at the user's own expense, monitoring facilities to allow inspection, sampling and flow measurement of the building sewer and/or internal drainage systems. The monitoring facility should normally be situated on the user's premises, but the City may, when such a location would be impractical or cause undue hardship on the user, allow the facility to be constructed in the public street or sidewalk area and located so that it will not be obstructed by landscaping or parked vehicles.
There shall be ample room in or near such sampling manhole or facility to allow accurate sampling and preparation of samples for analysis. The facility, sampling and measuring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the user.
Whether constructed on public or private property, the sampling and monitoring facilities shall be provided in accordance with the city's requirements and all applicable local construction standards and specifications. Construction shall be completed within 90 days following written notification by the city.
The City may inspect the facilities of any user to ascertain whether or not the purposes of this chapter are being met and all requirements are being complied with. Persons or occupants of premises where wastewater is created or discharged shall allow the City or its representative ready access at all reasonable times all parts of the premises for the purposes of inspection, sampling or records examination or in the performance of any of his, her or its duties. The city, the approval authority, the MDEQ and the EPA may set upon the user's property such devices as are necessary to conduct sampling, inspection, compliance monitoring and/or metering operations. Where a user has security measures in force which would require property identification and clearance before entry into its premises, the user shall make necessary arrangements with its security guards so that, upon presentation of suitable identification, the city, the approval authority, the MDEQ or the EPA will be permitted to enter, without delay, for the purposes of performing its specific responsibilities.
Users shall provide necessary wastewater treatment as required to comply with this chapter and shall achieve compliance with all federal categorical pretreatment standards within the time limitations specified by the federal pretreatment regulations. Any facilities required to pretreat wastewater to a level acceptable to the City shall be provided, operated and maintained at the user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the City for review and shall be acceptable to the City before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the City under this chapter. Any subsequent changes in the pretreatment facilities or methods of operation shall be reported to and be acceptable to the City prior to the user's initiation of the changes.
Industrial users must operate their treatment systems at all times. Bypasses are allowed only if it does not cause a violation of applicable categorical pretreatment standards or local limits and it is for "essential maintenance." Bypasses are excused if the bypass was unavoidable to prevent loss of life, personal injury or severe property damage and there were no feasible alternatives. Prior notification to the wastewater plant Superintendent shall be made if the industrial user knows, in advance, of the need for a bypass. All bypasses require oral notice to the wastewater plant within 24 hours and written notice within five days.
Existing sources which become industrial users subsequent to promulgation of an applicable categorical standard shall be considered existing industrial users except where such sources meet the definition of a new source as defined in § 115-2. New sources shall install and have in operating condition, and shall "start up" all pollution control equipment required to meet applicable pretreatment standards before beginning to discharge. Within the shortest feasible time (not to exceed 90 days), new sources must meet all applicable pretreatment standards.
All records relating to compliance with pretreatment standards shall be made available to officials of the EPA or the approval authority upon request.
Information and data on a user obtained from reports, questionnaires, permit applications, permits and monitoring programs and inspections shall be available to the public or other governmental agency without restriction unless the user specifically requests and is able to demonstrate to the satisfaction of the City that the release of such information would divulge information, processes or methods of production entitled to protection as trade secrets of the user.
When requested by the person furnishing a report, the portions of a report which might disclose trade secrets or secret processes shall not be made available for inspection by the public but shall be made available upon written request to governmental agencies for uses related to this chapter, the national pollutant discharge elimination system (NPDES) permit, the state disposal system permit and/or the pretreatment program. However, such portions of a report shall be available for use by the state or any state agency in judicial review or enforcement proceedings involving the person furnishing the report. Wastewater constituents and characteristics will not be recognized as confidential information.
Information accepted by the City as confidential shall not be transmitted to any governmental agency or to the general public by the City until and unless a ten-day notification is given to the user.
The City may suspend the wastewater treatment service and/or a wastewater discharge permit when such suspension is necessary, in the opinion of the city, in order to stop an actual or threatened discharge which presents or may present an imminent or substantial endangerment to the health or welfare of persons or the environment, which causes interference to the POTW or which causes the City to violate any condition of its NPDES permit.
Any person notified of a suspension of the wastewater treatment service and/or the wastewater discharge permit shall immediately stop or eliminate the contribution. If the person fails to comply voluntarily with the suspension order, the City shall take steps as deemed necessary, including immediate severance of the sewer connection, to prevent or minimize damage to the POTW system or endangerment to any individual. The City shall reinstate the wastewater discharge permit and/or the wastewater treatment service if, in its judgment, the noncomplying discharge has been eliminated. A detailed written statement submitted by the user describing the causes of the harmful contribution and the measures taken to prevent any future occurrence shall be submitted to the City within 15 days of the date of the occurrence.
The Superintendent may revoke a wastewater discharge permit for good cause, including, but not limited to, the following reasons:
Failure to notify the Superintendent of significant changes to the wastewater prior to the changed discharge;
Failure to provide prior notification to the Superintendent of changed conditions pursuant to § 115-13F of this chapter;
Misrepresentation or failure to fully disclose all relevant facts in the wastewater discharge permit application;
Falsifying self-monitoring reports;
Tampering with monitoring equipment;
Refusing to allow the Superintendent timely access to the facility premises and records;
Failure to meet effluent limitations;
Failure to pay fines;
Failure to pay sewer charges;
Failure to meet compliance schedules;
Failure to complete a wastewater survey or the wastewater discharge permit application;
Failure to provide advance notice of the transfer of business ownership of a permitted facility; or
Violation of any pretreatment standard or requirement, or any terms of the wastewater discharge permit or this chapter.
Wastewater discharge permits shall be voidable upon cessation of operations or transfer of business ownership. All wastewater discharge permits issued to a particular user are void upon the issuance of a new wastewater discharge permit to that user.
Notices of violation.
Whenever the City finds that any user has violated or is violating any of the provisions of this chapter, or a wastewater discharge permit or order issued hereunder, or any other prohibition, limitation or requirement contained in this chapter, the City may serve upon such person a written notice of violation. Within 15 days of the date of the notice or within such later time as the City may designate as appropriate in the notice, a plan for the satisfactory correction thereof shall be submitted to the City by the user unless there is an immediate threat to health, property or environmental quality which is treated as an emergency. Immediate response is required in such case, and the City may require the user to halt the discharge or chose to terminate service.
Submission of a plan in no way relieves the user of liability for any violation occurring before or after receipt of the notice of violation. Nothing in this section shall limit the authority of the Superintendent to take action, including emergency actions or any other enforcement action, without first issuing a notice of violation.
Consent orders. The city, at its discretion, may enter into a consent order to establish an agreement with any user responsible for any noncompliance or violation. Such consent order shall include specific action to be taken by the user to correct the noncompliance or violation within a specified time period, and may include stipulated penalties to insure compliance with the requirements of such consent order.
The City may order any user who causes or allows an unauthorized discharge to enter the POTW to show cause before the City Council why the proposed enforcement action should not be taken. A notice shall be served on the user specifying the time and place of a hearing to be held by Council regarding the violation, the reasons why the action is to be taken and the proposed enforcement action, and directing the user to show cause before Council why the proposed enforcement action should not be taken. The notice of the hearing shall be served personally or by registered or certified mail (return receipt requested) at least 10 days before the hearing. Service may be made on any agent or officer of a corporation.
Council may conduct the hearing and take the evidence or may designate any of its members or any officer or employee of the assigned department to:
Issue, in the name of Council, notices of hearings requesting the attendance and testimony of witnesses and the production of evidence relevant to any matter involved in such hearings;
Take the evidence; and
Transmit a report of the evidence and hearing, including transcripts and other evidence, together with recommendations to Council for action thereon.
At any hearing held pursuant to this chapter, testimony taken must be under oath and recorded stenographically. The transcript, so recorded, will be made available to any member of the public or to any party to the hearing upon payment of the usual charges therefor.
After Council has reviewed the evidence, it may:
Take into consideration information that, if it can be proven, the user did not violate any provision of this chapter or a permit issued under this chapter, or did not know or have reason to know, that its discharge, violated any provision of this chapter or a permit issued under this chapter;
Instruct the Superintendent to seek civil fines and relief or prosecute the user for violation of this chapter; and/or
If the violation is flagrant enough to endanger the health, safety and welfare of the inhabitants or residents to the city, issue an order to the user responsible for the discharge directing that, following a specified time period, if any, the sewer service will be discontinued unless adequate treatment facilities, devices or other related appurtenances have been installed on existing treatment facilities, directives as are necessary and appropriate may be issued.
The City shall provide annual public notification in the largest daily newspaper covering the municipality, a list of the users which, during the previous 12 months, were in significant noncompliance with applicable pretreatment standards and requirements.
Such annual publication shall be made in the first publication of the newspaper in December of each year.
Any user or any interested party may request, in writing, an interpretation or ruling by the City on any matter covered by this chapter and shall be entitled to a prompt written reply within 15 business days of the date of the request. If such inquiry is by a user and deals with matters of performance or compliance with this chapter for which enforcement activity relating to an alleged violation is the subject, receipt of a user's request shall not stay such enforcement proceedings. Appeal of any final judicial order entered pursuant to this chapter may be taken in accordance with local and state law.
Any user that experiences an upset in operations, which upset places the user in a temporary state of noncompliance with this chapter, shall inform the City thereof within 24 hours of first awareness of the commencement of the upset. Where such information is given orally, a written follow-up report thereof shall be filed by the user with the City within five days. The report shall specify:
A description of the upset, the cause thereof and the upset's impact on a user's compliance status;
The duration of noncompliance, including exact dates and times of noncompliance, and if the noncompliance continues, the time by which compliance is reasonably expected to occur; and
All steps taken or to be taken to reduce, eliminate and prevent a recurrence of such an upset or other conditions of noncompliance.
The City and each industrial user shall make and retain records of industrial discharge data pursuant to 40 CFR, Section 403.12. Such records must be maintained for three years. Any records relating to unresolved litigation must be maintained during the period of litigation and for three years following resolution of the litigation.
No user shall violate an order of Council or fail to comply with any of the provisions of this chapter or any order, rule, regulation or permit issued under this chapter.
No person shall knowingly make any false statement or representation about the pretreatment of the discharge or the discharge itself or make any false statement or representation or certification in any application, record, report, plan or other document filed or required to be maintained pursuant to this chapter or the wastewater discharge permit. No person shall knowingly falsify, tamper with or render inaccurate any monitoring device or method required by this chapter.
No person shall violate or fail to comply with any of the provisions of this chapter.
Municipal civil infractions.
Violation as municipal civil infraction. Except as provided by Subsection B of this section, a person who violates any provision of this chapter (including, but not limited to, any notice, order, permit, decision or determination promulgated under this chapter) is responsible for a municipal civil infraction, subject to payment of a civil fine of not less than $1,000 per day for each infraction and not more than $10,000 per day for each infraction, plus costs and other sanctions.
Repeat offenses; increased fines. Increased fines may be imposed for repeat offenses. As used in this section, "repeat offense" means a second (or any subsequent) municipal civil infraction violation of the same requirement or provision of this chapter committed by a person within any ninety-day period and for which the person admits responsibility or is determined to be responsible. The increased fine for a repeat offense under this chapter shall be as follows:
Amount of fines.
Municipal civil infraction citations. Subject to the minimum fine amounts specified in Subsection A(1) and (2), the following factors shall be considered by the court in determining the amount of a municipal civil infraction fine following the issuance of a municipal civil infraction citation for a violation of this chapter: the type, nature, severity, frequency, duration, preventability, potential and actual effect, and economic benefit to the violator (such as delayed or avoided costs or competitive advantage) of a violation; the violator's recalcitrance or efforts to comply; the economic impacts of the fine on the violator; and such other matters as justice may require. A violator shall bear the burden of demonstrating the presence and degree of any mitigating factors to be considered in determining the amount of a fine. However, mitigating factors shall not be considered unless it is determined that the violator has made all good faith efforts to correct and terminate all violations.
Municipal civil infraction notices; schedule of fines.
The amount of a municipal civil infraction fine due in response to the issuance of a municipal civil infraction notice for a violation under Subsection A shall be according to the following schedule:
A copy of this schedule shall be posted at the office of the Clerk in City of Rockwood.
Authorized City official. The Superintendent (and any representative designated by the Superintendent) is hereby designated as the authorized City official to issue municipal civil infraction citations and municipal civil infraction violation notices for violations of this chapter.
Criminal penalties; imprisonment. Any person who at the time of a violation knew that a pollutant or substance was discharged contrary to any provision of this chapter, or contrary to any notice, order, permit, decision or determination promulgated, issued or made under this chapter and knowingly failed to report or take appropriate action required under this chapter; or intentionally makes a false statement, representation, or certification in an application for, or form pertaining, to a permit, or in a notice, report, or record required by this chapter, or in any other correspondence or communication, written or oral, with the City regarding matters regulated by this chapter; or intentionally falsifies, tampers with, or renders inaccurate any sampling or monitoring device or record required to be maintained by this chapter; or commits any other act that is punishable under state law by imprisonment for more than 90 days shall, upon conviction, be guilty of a misdemeanor punishable by a fine of $500 per violation, per day, or imprisonment for up to 90 days, or both in the discretion of the court.
Continuing violation. Each act of violation, and each day or portion of a day that a violation of this chapter, or of any permit or order issued or entered into under this chapter constitutes a separate offense and shall be, in itself, subject to separate penalties or sanctions as a separate offense.
Injunction. In addition to any remedies available at law, the City may bring an action for an injunction or other process against a person to restrain, prevent or abate any violation of this chapter of the Code of the City of Rockwood.
