(A) Baseline monitoring reports.
(1) Within 180 days after the effective date of a categorical pretreatment standard, or the final administrative decision on a category determination under 40 C.F.R. 403.6(a)(4), whichever is later, existing categorical users currently discharging to or scheduled to discharge to the wastewater treatment plant shall submit to the wastewater treatment plant superintendent a report which contains the information listed in division (A)(2) below. Noncategorical industries at the request of the wastewater treatment plant superintendent shall also submit a baseline report within 180 days of commencement of discharge. New sources and existing sources that become industrial users subsequent to promulgation of categorical standards are required to submit baseline monitoring reports at least 90 days prior to commencement of discharge.
(2) Users described above shall submit the information set forth below.
(a) Identifying information. The name and address of the facility, including the name of the operator and owner.
(b) Environmental permits. A list of any environmental control permits held by or for the facility.
(c) Description of operations. A brief description of the nature, average rate of production, and standard industrial classifications of the operations(s) carried out at the facility. This description should include a schematic process diagram which indicates points of discharge to the wastewater treatment plant from the regulated process.
(d) Flow measurement. The user shall submit information showing the measured average daily and maximum daily flow to the wastewater treatment plant from regulated process streams and other streams necessary in determining compliance with applicable regulations.
(e) Measurement of pollutants. The user shall identify the pretreatment standards applicable to each regulated process. In addition, the user shall submit the results of sampling and analysis identifying the nature and concentration of regulated pollutants. The samples shall be representative of daily operations. A minimum of four grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide and volatile organics. For all other pollutants, 24-hour composite samples must be obtained through flow proportioned composite sampling techniques where feasible.
(f) Certification. A statement reviewed by an authorized representative and certified 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 to meet the pretreatment standards and requirements.
(g) Additional pretreatment and/or operation and maintenance activities.
1. Where additional pretreatment and/or operation and maintenance activities will be required to comply with this section, the industry shall provide a declaration of the shortest schedule by which the discharger will provide such additional pretreatment and/or implementation of additional pretreatment and/or implementation of additional operational and maintenance activities. The schedule shall contain milestone dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the discharger to comply with the requirements of this chapter including, but not limited to dates relating to hiring an engineer, hiring other appropriate personnel, completing preliminary plans, completing final plans, executing contract for major components, commencing construction, completing construction, and all other acts necessary to achieve compliance with this chapter. Under no circumstances shall the time increment for any single step directed toward compliance exceed nine months.
2. Not later than 14 days following each milestone date in the schedule and final date for compliance, the industry shall submit a progress report to the wastewater treatment plant superintendent, including no less than a statement as to whether or not it complied with the increment of progress represented by that milestone date and if not, the date of which it expects to comply with this increment of progress, the reason for delay, and the steps being taken by the industry to return the construction to the approved schedule. In no event shall more than nine months elapse between such progress reports to the wastewater treatment plant superintendent.
(h) Notification. All industrial users are required to promptly notify the wastewater treatment plant in advance of the potential for a slug discharge, discharge of a hazardous waste, or substantial changes in volume or character of discharges.
(B) Industries regulated by applicable federal standards shall comply with the following items.
(1) Report on compliance with categorical pretreatment standard deadline. 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 wastewater treatment plant, any industrial user subject to pretreatment standards and requirements shall submit to the wastewater treatment plant superintendent a report containing the information described in division (A) above. For industrial users subject to equivalent mass or concentration limits established by the wastewater treatment plant 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.
(2) Periodic report on continued compliance.
(a) Any discharger subject to a categorical pretreatment standard set forth in this chapter after the compliance date of such pretreatment standard, or, in the case of a new discharger, after commencement of the discharge to the authority, or significant non-categorical discharger shall submit to the wastewater treatment plant superintendent during the months of June and December, unless required more frequently by the wastewater treatment plant superintendent, a report indicating the nature and concentration of pollutants in the discharge which are limited by pretreatment standards and the measured or estimated average and maximum daily flows for the reporting period. All periodic compliance reports must be signed and certified in accordance with division (A)(2)(f) of this section.
(b) All wastewater samples must be representative of the user’s discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
(c) If a user subject to the reporting requirement in this section monitors any pollutant more frequently than required by the wastewater treatment plant superintendent, using the procedures prescribed in § 50.21 of this chapter, the results of this monitoring shall be included in the report.
(3) Reports of changed conditions. Each user must notify the wastewater treatment plant superintendent of any planned significant changes to the user’s operations or system which might alter the nature, quality, or volume of its wastewater at least 30 days before the change.
(4) Reports of potential problems.
(a) In the case of any discharge, including, but not limited to, accidental discharges, discharges of a non-routine, episodic nature, a non-customary batch discharge, or a slug load, that may cause potential problems for the wastewater treatment plant, the user shall immediately telephone and notify the wastewater treatment plant superintendent of the incident. This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective action taken by the user.
(b) This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective action taken by the user.
(5) Notice of violation/repeat sampling and reporting. If sampling performed by a user indicates a violation, the user must notify the wastewater treatment plant superintendent within 24 hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the wastewater treatment plant superintendent within 30 days after becoming aware of the violation. The user is not required to resample if the wastewater treatment plant superintendent monitors at the user’s facility at least once a month, or if the wastewater treatment plant superintendent samples between the users initial sampling and when the user receives the results of this sampling.
(6) Analytical requirements. All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report shall be performed in accordance with the techniques prescribed in 40 C.F.R. pt. 136, unless otherwise specified in an applicable categorical pretreatment standard. If 40 C.F.R. pt. 136 does not contain sampling or analytical techniques for the pollutant in question, sampling and analyses must be performed in accordance with procedures approved by EPA.
(7) Sample collection.
(a) Except as indicated in division (B)(2)(7)(b) below, the user must collect wastewater samples using flow proportional composite collection techniques. In the event flow proportional sampling is infeasible, the wastewater treatment plant superintendent may authorize the use of time proportional sampling or a minimum of four grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged. In addition, grab samples may be required to show compliance with instantaneous discharge limits.
(b) Samples for oil and grease, temperature, pH, cyanide, phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques.
(8) Timing. Written reports will be deemed to have been submitted on the date postmarked. For reports which are not mailed, postage prepaid, into a mail facility serviced by the United States Postal Service, the date of receipt of the report shall govern.
(10) Record keeping. Users subject to the reporting requirements of this chapter shall retain, and make available for inspection and copying, all records of information obtained pursuant to any monitoring activities required by this chapter and any additional records of information obtained pursuant to monitoring activities undertaken by the user independent of such requirements and documentation associated with Best Management Practices. Records shall include the date, exact place, method, and time of sampling, and the name of the person(s) taking the samples; the dates analyses were performed; who performed the analyses; the analytical techniques or methods used; and the results of such analyses. These records shall remain available for a period of at least three years. This period shall be automatically extended for the duration of any litigation concerning the user or the city, or when the user has been specifically notified of a longer retention period by the wastewater treatment plant superintendent.
(11) Certification statement. All permit applications, user reports and waivers are required to include and sign the following:
“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 fine and imprisonment for knowing violations.”
(C) Publication of users in significant noncompliance.
The Board of Public Utilities shall publish annually, in the largest daily newspaper published in the city where the wastewater treatment plant is located, a list of the users which during the previous 12 months, were in significant noncompliance with applicable pretreatment standards and requirements.
(D) Protection from accidental discharge.
(1) Each industrial user shall provide protection from accidental discharge of prohibited materials or other wastes regulated by this chapter. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner or operators own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the city engineer for review, and shall be approved by him or her before construction of the facility. Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify his or her facility as necessary to the requirements of this chapter.
(2) If, for any reason, a facility does not comply with or will be unable to comply with any prohibition or limitations in this chapter, the facility responsible for such discharge shall immediately notify the wastewater treatment plant superintendent so that corrective action may be taken to protect the treatment system. In addition, a written report addressed to the wastewater treatment plant detailing the date, time and cause of the accidental discharge, the quantity and characteristics of the discharge, shall be filed by the responsible industrial facility within five days of the occurrence of the noncomplying discharge.
