Chapter 3745-36 | Permit Program Regulating Discharge of Nondomestic Wastewater into a POTW

 
 
 
Rule
Rule 3745-36-01 | Purpose and applicability.
 

(A) The purpose of this chapter is to establish, as a part of a state pretreatment program under Chapter 6111. of the Revised Code, both of the following:

(1) A permit program regulating the discharge of nondomestic wastewater into a POTW to assure compliance with pretreatment standards in this chapter.

(2) Enforceable state requirements and standards regulating the introduction of pollutants into POTWs by industrial users.

(B) This chapter has the following objectives:

(1) To prevent the introduction of pollutants that will interfere with the operation of a treatment works into a POTW, including interference with the use or disposal of the POTW's sewage sludge.

(2) To prevent the introduction of pollutants into a POTW that will pass through the treatment works or otherwise be incompatible with such works.

(3) To improve opportunities to recycle and reclaim municipal and industrial wastewaters and sludges.

(C) In accordance with section 6111.032 of the Revised Code, nothing in this chapter is intended to supersede the primacy of the POTW in the regulation of the POTW's collection system and treatment works. All local laws, regulations, and ordinances shall apply as long as these requirements are as stringent as, or more stringent than, any set forth in the pretreatment rules under Chapter 3745-3 of the Administrative Code and indirect discharge permit rules under this chapter.

(D) The provisions in this chapter apply to both of the following:

(1) Pollutants from nondomestic sources covered by pretreatment standards that are indirectly discharged into, or transported by truck or rail or otherwise introduced into a POTW that is not administering an approved pretreatment program, as defined in this chapter. Pretreatment standards do not apply to sources connected to a sewer that is neither connected to a POTW nor discharging directly into a POTW.

(2) As defined in rule 3745-36-02 of the Administrative Code, industrial users that discharge nondomestic wastewater to a POTW that is not administering an approved pretreatment program. Industrial users which discharge nondomestic wastewater to a POTW that is administering an approved pretreatment program are subject to the pretreatment rules in Chapter 3745-3 of the Administrative Code.

(B) The requirement to obtain an individual indirect discharge permit in accordance with this rule or coverage under an indirect discharge permit-by-rule as specified in rule 3745-36-06 of the Administrative Code shall not apply to any industrial user that is under the regulatory jurisdiction of a POTW that has an approved pretreatment program in accordance with the provisions of Chapter 3745-3 of the Administrative Code, except in the context of an enforcement action.

(C) Where a POTW's pretreatment program approval has been withdrawn or revoked, all significant industrial users and non-significant categorical industrial users of the POTW shall be required to apply for an indirect discharge permit in accordance with this chapter no later than ninety days from the date on which the industrial user was notified of the withdrawal or revocation of the pretreatment program approval.

(D) New individual indirect discharge permits. Industrial users required to obtain an individual indirect discharge permit for the first time shall submit the application required in paragraph (H) of this rule. In addition, the application shall include an authorization to discharge by the POTW, as described in paragraph (I) of this rule. A complete application shall be submitted in accordance with the corresponding time frame, as follows:

(1) At least one hundred eighty days prior to commencement of discharge for new sources, as defined in rule 3745-36-02 of the Administrative Code.

(2) Within the timeframe specified by Ohio EPA upon notifying the industrial user of the user's requirement to apply for and obtain an individual indirect discharge permit.

(E) Renewal of individual indirect discharge permits.

(1) Any permittee who wishes to continue to discharge after the expiration of the permittee's individual indirect discharge permit shall submit a complete application for renewal of the permit at least one hundred eighty days prior to the expiration of the permit. The application shall contain the information required in paragraph (H) of this rule. If the industrial user wishes to request less stringent permit conditions, new pollutants, or increases in pollutant concentrations or loadings, the industrial user's application shall include the authorization to discharge by the POTW, as described in paragraph (I) of this rule.

(2) Individual indirect discharge permits shall be renewed in accordance with the provisions for issuance of permits under this chapter.

(3) In renewing a permit, the director shall consider the compliance history of the permit holder and may deny the renewal if the director determines that the permit holder has not complied with the terms and conditions of the existing permit. If a permit renewal application is submitted at least one hundred eighty days prior to the expiration date of the existing permit, and the director proposes to deny the renewal of the permit in accordance with rule 3745-49-05 of the Administrative Code, the expired permit shall continue to be in effect in accordance with section 119.06 of the Revised Code until such time as the director issues a final action.

(iv) Change facility name when no change of ownership has occurred.

(4) Submittals requesting a modification of the individual indirect discharge permit.

(a) Except for minor modifications, applications for modifications of individual indirect discharge permits at the request of the permittee shall include the information required in paragraphs (H) and (I) of this rule and a description of the proposed change. This information shall be submitted on current forms prepared by and obtained from Ohio EPA and shall contain such information as Ohio EPA deems necessary.

(b) For minor modification requests, as described in paragraph (F)(3) of this rule, the industrial user shall describe the requested change and any other information required by the Ohio EPA.

(5) A modification application for an individual indirect discharge permit submitted by the permittee shall be signed using the same signatory requirements required for a permit application pursuant to paragraph (H)(3) of this rule.

(G) Transfer of individual indirect discharge permits. An individual indirect discharge permit may be transferred by the permittee to a new owner or operator only through a minor permit modification, in accordance with paragraph (F)(3) of this rule, to identify the new permittee and to incorporate such other requirements as deemed necessary by the director to effect the transfer.

(H) Applications for individual indirect discharge permits.

(1) Applications for individual indirect discharge permits shall be submitted on current forms prepared by and obtained from Ohio EPA, and shall contain such information as Ohio EPA deems necessary. The director may require as a permit condition or otherwise, electronic submittal of an application using information systems compatible with those of Ohio EPA.

(a) A report indicating the nature and concentration of pollutants in the discharge that are limited by pretreatment standards.

(b) A record of measured or estimated average and maximum daily flows for the reporting period for the discharge to the POTW, reporting the measured average daily and maximum daily flow, in gallons per day, to the POTW. Ohio EPA may allow for verifiable estimates of these flows where justified by cost or feasibility considerations. The reported flow information shall include all of the following information:

(i) Regulated process streams.

(ii) Other streams as necessary to allow use of the combined wastestream formula in 40 C.F.R. 403.6.

(iii) Any other more specific or detailed flow rate information requested by Ohio EPA.

(c) Where Ohio EPA has imposed mass limitations on industrial users, the mass of pollutants in the discharge from the industrial user relevant to such mass limitations.

(d) For categorical industrial users subject to equivalent mass or concentration limits established by Ohio EPA, a reasonable measure of the user's long- term production rate.

(e) For industrial users subject to categorical pretreatment standards expressed only in terms of allowable pollutant discharge per unit of production (or other measure of operation), the user's actual average production rate for the reporting period.

(3) In cases where the pretreatment standard requires compliance with a BMP or a pollution prevention alternative, the report shall include documentation required by Ohio EPA or the pretreatment standard necessary to determine the compliance status of the user.

(4) For mid-tier categorical industrial users as authorized in accordance with rule 3745-36-09 of the Administrative Code, Ohio EPA may reduce the frequency of the reporting specified in paragraph (A)(2)(a) of this rule to no less than once per year, unless required more frequently in the pretreatment standard.

(5) For categorical industrial users subject to categorical standards for electroplating (40 C.F.R. Part 413), metal finishing (40 C.F.R. Part 433), and electrical and electronic component manufacturing (40 C.F.R. Part 469), in lieu of requiring monitoring for total toxic organics (TTOs), Ohio EPA may allow for implementation of a certified total toxic organics management plan (TOMP), as described in rule 3745-36-10 of the Administrative Code.

(B) Sampling and analysis performed in preparation of any report required by this chapter shall be conducted in accordance with all of the following:

(1) The individual indirect discharge permit application, initial compliance report, and periodic compliance report required in this chapter, shall be based upon data obtained through appropriate sampling and analysis performed during the period covered by the report, in which data is representative of conditions occurring during the reporting period.

(2) The Ohio EPA shall require that frequency of monitoring necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements.

(3) Grab samples shall be used for pH, hexavalent chromium, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds.

(4) For all other pollutants, twenty-four-hour composite samples shall be obtained through flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by Ohio EPA.

(5) Where time-proportional composite sampling or grab sampling is authorized by the director, the samples shall be representative of the discharge and the decision to allow the alternative sampling shall be documented by the industrial user.

(6) Using protocols (including appropriate preservation) specified in 40 C.F.R. 136 and appropriate U.S. EPA guidance, multiple grab samples collected during a twenty-four-hour period may be composited prior to the analysis as follows:

(a) For hexavalent chromium, cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field.

(b) For volatile organics and oil and grease the samples may be composited in the laboratory.

(c) Composite samples for other parameters unaffected by the compositing procedures as documented in approved U.S. EPA methodologies may be authorized by the director, as appropriate.

(7) For the individual indirect discharge permit application and the initial compliance report required in rules 3745-36-03 and 3745-36-09 of the Administrative Code:

(a) A minimum of four grab samples shall be used for pH, hexavalent chromium, cyanide, total phenols, oil and grease, sulfide, and volatile organics for facilities for which historical sampling data do not exist.

(b) For facilities for which historical sampling data are available, the director may authorize a requirement of fewer grab samples.

(c) For all other pollutants, twenty-four-hour composite samples shall be obtained through flow- proportional composite sampling techniques, unless flow-proportional sampling is waived by the director.

(d) In such cases, samples may be obtained through time-proportional composite sampling techniques or through a minimum of four grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged.

(8) For the periodic compliance report required by paragraph (A) of this rule, the Ohio EPA shall require the number of grab samples necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements. The required number of grab samples shall only apply for pollutants listed in paragraph (B)(3) of this rule, or where grab sampling is authorized by the director in accordance with paragraph (B)(5) of this rule.

(9) Samples shall be taken immediately downstream from pretreatment facilities, if such exist, or immediately downstream from the regulated process if no pretreatment exists. If the wastewaters regulated by categorical standards mix with other wastestreams prior to pretreatment, the user shall measure the flows and concentrations necessary to allow use of the combined wastestream formula under paragraph (H) of rule 3745-36-10 of the Administrative Code in order to evaluate compliance with the categorical pretreatment standards.

(10) Except as otherwise provided in this rule, sampling and analysis shall be performed in accordance with the techniques prescribed in 40 C.F.R. 136. Where 40 C.F.R. 136 does not contain sampling or analytical techniques for the pollutant in question, or where the director determines that the 40 C.F.R. 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analysis shall be performed by using analytical methods or other applicable sampling and analytical procedures approved by the director.

(11) Except in the case of non-significant categorical industrial users, the Ohio EPA may perform the sampling and analysis required in this chapter in lieu of the industrial user. Where Ohio EPA performs the required sampling and analysis in lieu of the industrial user, both of the following apply:

(a) The industrial user will not be required to submit the compliance certification statement required in paragraph (C) of this rule.

(b) The industrial user will not be required to submit the report if Ohio EPA collects all the information required for the report.

(12) Resampling of a violation. Unless paragraph (B)(12)(c) of this rule applies, repeat sampling and analysis shall be performed within thirty days after the industrial user or Ohio EPA becomes aware of the violation. The responsible party for resampling is determined by the following:

(a) If sampling performed by an industrial user indicates a violation, the user shall notify Ohio EPA within twenty-four 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 Ohio EPA within thirty days after becoming aware of the violation.

(b) If sampling and analysis performed by Ohio EPA under paragraph (B)(11) of this rule indicates a violation, Ohio EPA shall perform the repeat sampling and analysis unless Ohio EPA notifies the user of the violation and requires the user to perform the repeat analysis.

(c) Resampling is not required if either of the following apply:

(i) Ohio EPA performs sampling at the industrial user at a frequency of at least once per month.

(ii) Ohio EPA performs sampling at the user between the time when initial sampling was conducted and the time when the results of the initial sampling are received.

(13) If an industrial user subject to the reporting requirement in paragraph (A) of this rule monitors any regulated pollutant at the permitted sampling location more frequently than required by Ohio EPA, using the procedures described in paragraph (B)(10) of this rule, the results of this monitoring shall be included in the report.

(14) Ohio EPA may require an industrial user to install flow monitoring facilities, instruments, and recording devices to enable accurate measurement of flows as determined to be necessary.

(C) The reports and certifications required by this rule shall include the following certification statement and shall be signed by an authorized representative of the industrial user:

(1) "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.

(B) Initial compliance report. Within ninety days following the date for final compliance with applicable categorical pretreatment standards or, in the case of a new source, within ninety days following commencement of the introduction of wastewater into the POTW, any industrial user subject to categorical pretreatment standards shall submit to Ohio EPA a report containing all of the following information:

(1) Information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from each of the following:

(a) Regulated process streams.

(b) Other streams as necessary to allow use of the combined wastestream formula of 40 C.F.R. 403.6. The director may allow for verifiable estimates of these flows where justified by cost or feasibility considerations.

(2) Measurement of pollutants.

(a) The user shall identify the pretreatment standards applicable to each regulated process.

(b) Sampling and analysis shall be performed in accordance with paragraph (B) of rule 3745-36-08 of the Administrative Code.

(c) The user shall submit the results of sampling and analysis identifying the nature and concentration (or mass, where required by the standard or control authority) of regulated pollutants in the discharge from each regulated process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations. If the standard requires compliance with a BMP or a pollution prevention alternative, the industrial user shall submit documentation as required by Ohio EPA or the applicable standards to determine compliance with the standard.

(d) The user shall take a minimum of one representative sample from each sampling location, as approved by Ohio EPA, to comply with the requirements of this paragraph.

(e) Ohio EPA may allow the submission of a report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures.

(f) The report shall indicate the time, date and place, of sampling, and methods of analysis.

(3) For industrial users subject to equivalent mass or concentration limits established by Ohio EPA in accordance with the procedures in rule 3745-36-10 of the Administrative Code, this report shall contain a reasonable measure of the user's long-term production rate.

[Comment: A reasonable measure is a projection or estimation of the facility's production rate for the life of the individual indirect discharge permit. The industrial user shall derive these production rates to the best of the user's knowledge, and considering any available information representative of the facility.]

(4) For all 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.

(5) A statement, reviewed, signed, and certified by an authorized representative of the industrial user, as defined in paragraph (C) of rule 3745-36-08 of the Administrative Code, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance (O and M) or additional pretreatment is required for the industrial user to meet the pretreatment standards and requirements.

(C) Categorical industrial users shall comply with the limits under rule 3745-36-04 of the Administrative Code, and with any more stringent pretreatment standards, including local limits.

(D) Existing sources that become industrial users subsequent to promulgation of an applicable categorical pretreatment standard shall be considered existing industrial users except where such sources meet the definition of a new source as defined in rule 3745-36-02 of the Administrative Code.

(E) New sources shall comply with the pretreatment standard for new sources (PSNS) that is specified in the applicable subcategory of the categorical pretreatment standard.

(F) Except where expressly authorized to do so by an applicable categorical pretreatment standard or requirement, no industrial user shall ever increase the use of process water or, in any other way, attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with a pretreatment standard or requirement. The director may impose mass limitations on industrial users that are using, or attempt to use, dilution to meet applicable pretreatment standards or requirements, or in such other cases where the imposition of mass limitations is appropriate.

(G) Pollutant discharge limits in categorical pretreatment standards are expressed either as concentration or mass limits or both. When equivalent mass limits are provided, the Ohio EPA may use either concentration or mass limits for enforcement purposes. Limits in categorical pretreatment standards shall apply to the effluent of the process regulated by the standard, or as otherwise specified by the standard.

(H) Unless otherwise provided in an applicable categorical pretreatment standard, compliance with such standards shall be measured in accordance with the methods of analyses and sampling procedures specified under rule 3745-36-08 of the Administrative Code.

(I) In all cases in which a determination is sought by an industrial user concerning the applicability of a particular subcategory under the categorical pretreatment standards, the final determination issued under 40 C.F.R. 403.6 shall control the application of the appropriate subcategory. There shall be no right or procedure implied under this chapter for industrial users to seek such categorical determinations from the director other than through the procedures and within the requirements of 40 C.F.R. 403.6.

[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules and federal statutory provisions referenced in this rule, see rule 3745-36-02 of the Administrative Code.]

(A) Categorical industrial users shall comply with the requirements in rules 3745-36-08 and 3745-36-09 of the Administrative Code, and any alternative condition described in this rule that has been approved by Ohio EPA and incorporated into the categorical industrial user's indirect discharge permit or the director's written approval.

(B) Categorical industrial users may apply for reduced reporting or monitoring requirements, or alternative limits as follows:

(1) The categorical industrial user shall first submit the initial compliance report as described in paragraph (A) of rule 3745-36-09 of the Administrative Code, or a periodic compliance report as described in paragraph (B) of rule 3745-36-08 of the Administrative Code.

(2) The categorical industrial user shall submit a formal request to Ohio EPA for the approval of an alternative condition initially and prior to each subsequent renewal of such condition. The request shall include the information described in paragraphs (D) to (H) of this rule, as applicable, and the certification statement in paragraph (C)(1) of rule 3745-36-08 of the Administrative Code, and shall be signed by an authorized representative, as defined in paragraph (C)(2) of rule 3745-36-08 of the Administrative Code.

(3) Alternative conditions described in paragraphs (D) to (H) of this rule may only be implemented and enforced through the following methods, as applicable:

(a) Renewal of modification of an individual indirect discharge permit that includes alternative conditions described in paragraphs (D), (E), (F), and (H) of this rule.

(b) Renewal or modification of an individual indirect discharge permit or the director's written approval for the alternative condition described in paragraph (G) of this rule.

(4) Conditions described in this rule may only be authorized by Ohio EPA for the duration of the indirect discharge permit, but in no case longer than five years.

(5) Industrial users implementing any of the alternative conditions described in paragraphs (D) to (H) of this rule shall maintain compliance with the records retention requirements described in paragraphs (F) to (I) of rule 3745-36-08 of the Administrative Code. In addition, the industrial user shall maintain both of the following for a minimum of three years after the date on which they become ineffective:

(a) Documentation of all requests to implement an alternative condition described in paragraphs (D) to (H) of this rule, regardless of whether Ohio EPA approved the request.

(b) Any records which demonstrate compliance with the applicable alternative conditions described in paragraphs (D) to (H) of this rule.

(6) Industrial users implementing any of the alternative conditions described in paragraphs (D) to (H) of this rule shall maintain compliance with the notification requirements described in rule 3745-36-05 of the Administrative Code.

(C) Removal, revocation, or modification of alternative conditions:

(1) At any time, the director may remove, revoke, or modify alternative conditions described in paragraphs (D) to (H) of this rule through the following actions, as applicable:

(a) Remove, revoke, or modify an alternative condition described in paragraph (D), (E), (F) or (H) of this rule from an individual indirect discharge permit.

(b) Revoke the director's written approval of the TTO monitoring alternative described in paragraph (G) of this rule, or remove, revoke, or modify the TTO monitoring alternative from an individual indirect discharge permit.

(2) The director's decision to remove, revoke, or modify an alternative condition in accordance with paragraph (C)(1) of this rule may be based on:

(a) Noncompliance by the permittee with any terms or conditions of this rule or the individual indirect discharge permit.

(b) The industrial user's failure to disclose information in any application, or the industrial user's misrepresentation of facts.

(c) A categorical industrial user undergoes changes that result in the user no longer being classified as a categorical industrial user.

(d) Ohio EPA finds that the industrial user's discharge no longer meets the requirements for the applicable alternative conditions.

(D) Monitoring waivers. Ohio EPA may authorize an industrial user subject to at least one categorical pretreatment standard, except for centralized waste treatment facilities regulated by and defined in 40 C.F.R. 437, to forgo sampling of a pollutant regulated by a categorical pretreatment standard. This reduction in sampling may only be authorized by Ohio EPA if the industrial user has demonstrated through sampling and other technical factors that the pollutant is neither present nor expected to be present in the discharge, or is present only at background levels from intake water and without any increase in the pollutant due to activities of the industrial user. This authorization is subject to all of the following:

(1) Ohio EPA may authorize a waiver where a pollutant is determined to be present solely due to sanitary wastewater discharged from the facility, provided that the sanitary wastewater is not regulated by an applicable categorical standard and otherwise includes no process wastewater.

(2) In making a demonstration that a pollutant is not present, the industrial user shall provide data from at least one sampling of the facility's process wastewater prior to any treatment present at the facility that is representative of all wastewater from all processes. Non-detectable sample results may only be used as a demonstration that a pollutant is not present if the U.S. EPA approved analytical method from 40 C.F.R. 136 with the lowest method detection limit for that pollutant was used.

(3) Upon Ohio EPA's approval of the monitoring waiver and implementation of the industrial user's individual indirect discharge permit, the industrial user shall certify on each periodic compliance monitoring report required by paragraph (A) of rule 3745-36-08 of the Administrative Code with the following statement:

"Based on my inquiry of the person or persons directly responsible for managing compliance with the pretreatment standards under 40 C.F.R. [specify applicable national pretreatment standard part or parts], I certify that, to the best of my knowledge and belief, there has been no increase in the level of [list pollutant or pollutants] in the wastewaters due to the activities at the facility since submittal of the last periodic report under paragraph (A) of rule 3745-36-08 of the Administrative Code."

(4) In the event that a waived pollutant is found to be present or is expected to be present based on changes that occur in the industrial user's operations, the user shall immediately meet both of the following:

(a) Notify Ohio EPA in writing.

(b) Comply with the monitoring requirements specified in the categorical pretreatment standards and the provisions of the individual indirect discharge permit.

(5) The provision for a monitoring waiver does not relieve the industrial user of any other certification processes and requirements established by Ohio EPA or in categorical pretreatment standards, except as otherwise specified in the categorical pretreatment standard.

(E) Mid-tier categorical industrial user. For a mid-tier categorical industrial user as defined in rule 3745-36-02 of the Administrative Code, Ohio EPA may reduce the frequency for the periodic compliance reports described in paragraph (A) of rule 3745-36-08 of the Administrative Code to no less than once per year, unless required more frequently in the pretreatment standard or by the director.

(1) The industrial user shall submit a request to Ohio EPA for a determination of the user's status as a mid-tier categorical industrial user which shall include documentation that the industrial user meets all of the criteria of a mid-tier categorical industrial user. This request shall be signed in accordance with paragraph (C) of rule 3745-36-08 of the Administrative Code, and include the certification statement in paragraph (C)(1) of rule 3745-36-08 of the Administrative Code.

(2) The industrial user shall notify Ohio EPA immediately of any changes at the facility causing the user to no longer meet the definition of a mid-tier categorical industrial user in rule 3745-36-02 of the Administrative Code. Upon notification, the industrial user shall immediately begin complying with the minimum reporting requirement specified in paragraph (A) of rule 3745-36-08 of the Administrative Code.

(3) In accordance with paragraphs (F) to (I) of rule 3745-36-08 of the Administrative Code, the industrial user shall retain documentation to support its compliance with the definition of a mid-tier categorical industrial user in rule 3745-36-02 of the Administrative Code. The industrial user shall maintain these records for a period of three years after the expiration of the individual indirect discharge permit.

(F) Non-significant categorical industrial users. For a non-significant categorical industrial user as defined in rule 3745-36-02 of the Administrative Code, Ohio EPA may reduce or remove sampling requirements from the indirect discharge permit.

(1) The industrial user shall submit a request to Ohio EPA for a determination of the user's status as a non-significant categorical industrial user which shall include documentation that the industrial user meets all of the criteria of a non-significant categorical industrial user, as defined in rule 3745-36-02 of the Administrative Code. This request shall be signed in accordance with paragraph (C) of rule 3745-36-08 of the Administrative Code, and include the certification statement in paragraph (C)(1) of rule 3745-36-08 of the Administrative Code.

(2) The industrial user shall notify Ohio EPA immediately in writing of any changes at the facility causing the user to no longer meet the definition of a non-significant categorical industrial user in rule 3745-36-02 of the Administrative Code. The director's determination of a significant industrial user may be made for any of the reasons described in paragraph (C) of this rule.

(3) Facilities determined by Ohio EPA to be a non-significant categorical industrial user shall annually submit the following certification statement, signed by an authorized representative, as defined in paragraph (C) of rule 3745-36-08 of the Administrative Code. Except for the periodic compliance report described in paragraph (A) of rule 3745-36-08 of the Administrative Code, this certification shall be accompanied by any additional reports required by Ohio EPA, if any:

"Based on my inquiry of the person or persons directly responsible for managing compliance with the categorical pretreatment standards under 40 C.F.R. [specify applicable national pretreatment standard part or parts], I certify that, to the best of my knowledge and belief, during the period from [specify month, day and year] to [specify month, day and year]:

(a) The facility described as [insert facility name] met the definition of a non-significant categorical industrial user as defined in rule 3745-36-02 of the Administrative Code.

(b) The facility complied with all applicable pretreatment standards and requirements during this reporting period.

(c) The facility never discharged more than one hundred gallons of total categorical wastewater on any given day during this reporting period. This compliance certification is based upon the following information: [specify information]."

(G) Total toxic organic monitoring. The Ohio EPA may allow the implementation of a certified total organics management plan (TOMP) in lieu of requiring monitoring for total toxic organics (TTOs). The implementation of a certified TOMP is only applicable to categorical industrial users subject to categorical standards for electroplating (40 C.F.R. Part 413), metal finishing (40 C.F.R. Part 433), and electrical and electronic component manufacturing (40 C.F.R. Part 469).

(ii) A description of the procedure that will provide routine and detailed visual inspections to ensure the absence of leaking storage containers. Visual inspections shall be conducted at least once per week.

(iii) A description of how all employees are trained in the proper use, collection, and storage of all chemicals they work with.

(iv) A simple but complete floor plan showing the storage location of toxic organics prior to use, in use and toxic organic waste awaiting disposal. This plan shall include all floor drains, dikes, and containment areas in the storage facility.

(f) A spill or leak notification plan and containment procedures. If a spill or leak containing a TTO enters the process wastewaters and discharges to a POTW or surface waters, the POTW and Ohio EPA shall be promptly notified by the industrial user within twenty-four hours of discovery. Information regarding the facility, chemicals spilled and remedial actions shall be provided in the notification. The spill or leak notification plan shall also include, at a minimum:

(i) The name of the individual responsible for implementing the TOMP.

(ii) The name of the facilitys emergency response coordinator.

(iii) A list of agencies to be contacted during an emergency and their telephone numbers shall also be posted where organics are used and stored.

(iv) A description of practices to be followed in the event of a spill or leak.

(v) A description of equipment and supplies on site to contain and clean up spills and leaks.

(2) Initial sampling. The facility's effluent shall be sampled and analyzed for all toxic organic compounds, as indicated on the list included in the appropriate categorical standard.

(a) Samples shall be collected and analyzed in accordance with 40 C.F.R. 136, with appropriate detection levels.

(b) The reporting form from the laboratory analyzing the samples shall be included in the TOMP.

(c) The steps in the regulated process in which toxic organics are used shall be described.

(d) The source where toxic organics could be introduced into the wastestream besides those referenced in paragraph (G)(2)(c) of this rule shall be described.

(3) Certification eligibility. In order to qualify for the alternative in paragraph (G) of this rule, the following criteria shall be met:

(a) The baseline analysis shall show compliance with the appropriate TTO standards.

(b) An acceptable TOMP shall be submitted to Ohio EPA.

(c) The certification statement in paragraph (C)(1) of rule 3745-36-08 of the Administrative Code, signed by an authorized representative of the industrial user, as defined in paragraph (C)(2) of rule 3745-36-08 of the Administrative Code.

(d) The following certification statement shall be signed by an authorized representative of the industrial user, as defined in paragraph (C)(2) of rule 3745-36-08 of the Administrative Code and submitted with the TOMP and each subsequent periodic compliance report:

"Based on my inquiry of the person or persons directly responsible for managing compliance with the standard for total toxic organics (TTO), I certify that, to the best of my knowledge and belief, no discharge or dumping of concentrated toxic organics into the wastewaters has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the toxic organic management plan submitted to Ohio EPA."

(4) Ohio EPA and the POTW shall be notified if any production process is modified or if conditions change that affect the use or storage of toxic organics. Ohio EPA may require that additional sampling be performed.

(5) Certification re-evaluation. To continue implementation of the alternate TTO monitoring, the industrial user shall update the TOMP at least every permit cycle and at intervals no longer than five years. In addition, within twelve months of requesting re-evaluation, the industrial user shall conduct the initial sampling requirements described in paragraph (G)(2) of this rule. The industrial user shall submit the sampling results and updated TOMP to Ohio EPA for review and approval. A copy of this submittal shall also be sent to the POTW.

(6) Revocation of certification eligibility. The certification eligibility may be revoked if independent sampling reveals violations or results inconsistent with the values reported by the entity or for any of the reasons described in paragraph (C) of this rule.

(7) TTO monitoring shall resume upon the end or revocation of certification.

(H) Enforceable alternative limits.

(1) Categorical pretreatment standards shall apply to an industrial user unless an enforceable alternative limit to the standard is applicable to the industrial user under any of the following regulations:

(b) 40 C.F.R. 403.6(e) (combined wastestream formulas) to reflect a situation where process effluent is mixed prior to treatment with wastewater other than that generated by the regulated process.

(c) 40 C.F.R. 403.13 (fundamentally different factor variance) to reflect the existence of data and information that was not considered or available when the categorical pretreatment standard was promulgated.

(d) 40 C.F.R. 403.15 (net/gross calculation) to reflect the presence of pollutants in the intake water of an industrial user.

(e) 40 C.F.R. 403.6(c)(1) to reflect the conversion of mass-based limits into equivalent limits expressed either as mass of pollutant discharged per day or effluent concentration.

(f) 40 C.F.R. 403.6(c)(5) to reflect the conversion of concentration-based limits into equivalent mass-based limits.

(g) 40 C.F.R. 403.6(c)(6) to reflect the conversion of mass-based limits of the categorical pretreatment standards in 40 C.F.R. 414, 40 C.F.R. 419, and 40 C.F.R. 455 to concentration-based limits.

(2) In order for the alternative limit referenced in paragraph (H)(1) of this rule to be considered enforceable, compliance with the alternative limit shall be required by the individual indirect discharge permit issued to the industrial user by the director under section 6111.03 of the Revised Code.

(3) There shall be no right or procedure implied under this chapter for an industrial user, or any other person to seek an alternative limit to a categorical pretreatment standard other than through the procedures and within the requirements set forth in paragraphs (H)(1) and (H)(2) of this rule.

(4) Categorical industrial users shall comply with the limits under rule 3745-36-04 of the Administrative Code, and with any more stringent pretreatment standards, including local limits.
