(A) Required. It shall be unlawful for users to discharge into the POTW any wastewater which will cause interference or pass through, or otherwise not comply with the discharge prohibitions of § 52.51. It shall be unlawful for a significant industrial user to discharge into the POTW without a wastewater discharge permit from the Detroit Water and Sewerage Department. Unless otherwise expressly authorized by the Department through permit, order, rule or regulation, any discharge must be in accordance with the provisions of this chapter.
(1) All significant industrial users, which are in existence on the effective date of this chapter, shall apply for a wastewater discharge permit within 30 days of the effective date of this chapter. Significant industrial users who are currently operating with a valid wastewater discharge permit are not subject to this provision. These applications are to include all information specified in division (C) below and, where applicable, any additional information which may be needed to satisfy the federal baseline monitoring report requirements of 40 C.F.R. 403.12(b).
(2) All new significant users shall apply for a wastewater discharge permit at least 90 days prior to commencement of discharge. The application must include all information specified in division (C) below and, where applicable, any additional information that may be needed to satisfy the federal BMR requirements of 40 C.F.R. 403.12(b). Until a permit is issued and finalized by the Department, no discharge shall be made into the POTW.
(3) Any user, who proposes to discharge any wastewater other than sanitary or non-contact cooling water into the POTW, shall request approval from the Department for the discharge(s) at least 30 days prior to the commencement of the discharge.
(B) Permit application or reapplication. The Department may require any user to complete a questionnaire and/or a permit application and to submit the same to the Department for determining whether the industrial user is a significant user, or to determine changes in the wastewater discharges from a user's facility. Within 30 days of being so notified, a user shall comply with the Department's request in the manner and form prescribed by the Department. Failure of the Department to so notify a user shall not relieve the user of the duty to obtain a permit as required by this chapter.

(d) 1. Reports shall contain the results of representative sampling performed during the period covered by the report and of the discharge and analysis of pollutants contained therein, and, for significant industrial users subject to production based standards, shall be cross-referenced to the related flow or production and mass as required to determine compliance with the applicable pretreatment standards. The frequency of monitoring shall be as prescribed in the applicable general pretreatment regulations, being 40 C.F.R. Part 403, or by the Department, but no less than is necessary to assess and assure compliance by the industrial user with the most stringent applicable pretreatment standards and requirements. All sampling and analysis shall be performed in accordance with applicable regulations contained in 40 C.F.R. Part 136 and amendments thereto. Where 40 C.F.R. Part 136 does not include sampling or analytical techniques for the pollutants in question, sampling and analysis shall be performed using validated analytical methods approved by the Administrator.
2. If an industrial user monitors any pollutant more frequently than required by the Department using the procedures as prescribed in this section, the results of this monitoring shall be included in such report. The report shall state whether the applicable pretreatment standards are being met on a consistent basis and, if not, what additional operation and maintenance practices and/or pretreatment system improvements or changes are necessary to bring the industrial user into compliance with the applicable pretreatment standards.
(e) This report, and those required under § 52.51(C)(5) and divisions (E)(8)(b) and (c) above, shall include 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 designed 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 a fine and/or imprisonment for knowing violations." Said certification shall be signed by the facility's authorized representative, as defined in § 52.03. 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 satisfying the requirements of the authorized representative definition must be submitted to the Department prior to, or together with, any reports to be signed by an authorized representative.
(f) If sampling performed by a permittee indicates a violation, the user shall notify the Department within 24 hours of the time said user becomes, or should have become, aware of the violation. In addition, the user shall repeat the sampling and analysis, and submit the results of the repeat analysis to the Department within 30 days after said user becomes, or should have become, aware of the violation.
(9) In the event the Director determines that an industrial user is discharging substances in quality, quantity or at locations which may cause problems to the POTW, or the receiving stream, the Department has the authority to develop and enforce effluent limits applicable to the user. To the extent the Department seeks to impose restrictions in a permit which are more restrictive than established in this chapter, the Department shall provide written documentation to explain the greater restriction for protection against pass through, interference, or violation of the NPDES permit;
(10) Requirement for pollution prevention initiatives; and
(11) Other requirements reasonably necessary to ensure compliance with this section.
(F) Permit duration. Permits shall be issued for a specified time period. Except as deemed necessary by the Department, or as otherwise provided for under this division, permits shall be issued for a specified period of not more than five years nor less than one year. The existing permit for significant industrial users, who timely submit an application for permit reissuance to the Department, shall be automatically extended until a permit is issued as final.
(G) Permit modification.
(1) The terms and conditions of the permit may be subject to modification by the Department during the term of the permit as limitations or pretreatment standards and requirements identified in § 52.51 are amended, or other just cause exists. Just cause for a permit modification includes, but shall not be limited to, the following:
(a) Material or substantial changes to an industrial user's facility or operation, or changes in the characteristics of the industrial user's effluent. It shall be the industrial user's duty to request an application form and apply for a modification of the permit within 30 calendar days of the change;
(b) Change(s) in the Department's NPDES permit;
(c) Embodiment of the provisions of a legal settlement or of a court order;
(d) Any changes necessary to fulfill the Department's role as control authority;
(e) An industrial user's noncompliance with portions of an existing permit;
(f) A change of conditions within the POTW;
(g) A finding of interference or pass through attributable to the industrial user;
(h) Amendments to, or promulgation of, national categorical pretreatment standards or requirements including 40 C.F.R. Part 403 and those delineated in § 52.60. Permittees shall request an application form and apply to the Department for a modified permit within 90 days after the promulgation of a new or revised national categorical pretreatment standard to which the industrial user shall be subject. Information submitted pursuant to this chapter shall be confined to that information related to the newly promulgated or amended national categorical pretreatment standard or requirement. However, information previously submitted need not be duplicated, insofar as the previously submitted information continues to be current and applicable. In addition, the Department may initiate this action;
(i) Changes in the monitoring location. (See § 52.54);
(j) Typographical errors or omissions in permits;
(k) The Department may modify the permit on its own initiative based on its findings or reasonable belief of the above; or
(l) The user may request a modification of the permit.
(2) When initiated by the Department, the industrial user shall be informed of any proposed change in its permit. The Department will issue a draft permit and an industrial user has 30 days to file a response to the draft modified permit. Thereafter, the Department will issue a final permit and, unless appealed in accordance with the procedures contained in § 52.59, the permit will become effective 20 days after issuance.
(H) Permit custody and transfer. Wastewater discharge permits are issued to a specific person as defined herein for a specific discharge. A wastewater discharge permit shall not be reassigned or transferred or sold to a different person, new owner, new industrial user, different premises, or a new or changed operation without notice to and written approval of the Department, and providing a copy of the existing permit to the new owner or operator. It shall be the permit holder's duty to notify the Department of any such change at least 30 days before the date of the change. Wastewater discharge permits, which do not receive the written approval of the Department prior to the change, shall be null and void regardless of reassignment, or transfer, or sale. If it has occurred, the Department may revoke a permit. If a change takes place, the Department may require the application for a new or modified permit. Any succeeding person shall comply with the terms and conditions of any existing permit which the Department allows to be retained.
(I) Permit notification requirements. All industrial users shall promptly notify the Department in advance of any substantial change in the volume or character of pollutants in their discharge, including the listed or characteristic hazardous waste for which initial notification under 40 C.F.R. 403.12(p) has been made, request a permit application form, and apply for a modification of the permit at least 30 calendar days prior to the change. Failure of the industrial user to so apply shall be considered a violation of this chapter.
