Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations. In cases where the standard requires compliance with a BMP or a pollution prevention alternative, the industrial user shall submit documentation as required by the control authority or the applicable standards to determine compliance with the standard.
(c) The user shall take a minimum of one representative sample from each sampling location, as approved by the control authority, to comply with the requirements of this paragraph.
(d) Sampling and analyses shall be performed in accordance with paragraph (G) of this rule.
(e) The baseline report shall indicate the time, date and place, of sampling, and methods of analysis.
(f) The control authority may allow the submission of a baseline report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures.
(6) A statement, reviewed, signed, and certified by an authorized representative of the industrial user, as defined in paragraph (F) of this rule, certifying that the information reported is representative of normal work cycles and expected pollutant discharges to the POTW.
(7) A statement, reviewed, signed, and certified by an authorized representative of the industrial user, as defined in paragraph (F) of this rule, indicating whether pretreatment standards are being met on a consistent basis, and if not, whether additional operation and maintenance, or additional pretreatment is required by the industrial user to meet the pretreatment standards and requirements.
(8) If additional pretreatment operation and maintenance, or both, will be required to meet the categorical pretreatment standards, the shortest schedule by which the industrial user will provide such additional measures. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard.
(9) The schedule required by paragraph (C)(8) of this rule shall contain increments of progress in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the industrial user to meet the applicable categorical pretreatment standards (e.g., hiring an engineer, completing preliminary plans, completing final plans, executive contract for major components, commencing construction, completing construction, etc). No increment shall exceed nine months.
(10) Not later than fourteen days following each date in the schedule required by paragraph (C)(8) of this rule and the date for final compliance with the applicable categorical pretreatment standard or standards, the industrial user shall submit a progress report to the control authority including, at a minimum, whether or not compliance with the increment of progress has been met on such date and, if not, the date on which compliance with this increment of progress is expected, the reason for delay, and the steps being taken by the industrial user to return the construction to the schedule established. In no event shall more than nine months elapse between such progress reports to the control authority.

(iii) The written authorization is submitted to the control authority.
(e) If an authorization under paragraph (F)(2)(d) of this rule 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 paragraph (F)(2)(d) of this rule shall be submitted to the control authority prior to or together with any reports to be signed by an authorized representative.
(G) Sampling and analysis performed in preparation of any report required by this rule shall be conducted in accordance with all of the following:
(1) For the reports required in paragraphs (B) and (D) of this rule, 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; for facilities for which historical sampling data are available, the control authority may authorize a requirement of fewer grab samples. 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 control authority. 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.
(2) Samples should 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 should measure the flows and concentrations necessary to allow use of the combined wastestream formula under paragraph (I)(1) of rule 3745-3-09 of the Administrative Code in order to evaluate compliance with the categorical pretreatment standards.
(3) 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.
(4) Except in the case of non-significant categorical industrial users, the sampling and analysis required in paragraphs (B), (D), and (E) of this rule may be performed by the control authority in lieu of the industrial user. Where the POTW performs the required sampling and analysis in lieu of the industrial user all of the following apply:
(a) The user will not be required to submit the compliance certification statement required in paragraph (C)(6) of this rule.
(b) The industrial user will not be required to submit the report if the POTW solely collects all of the information required for the report.
(c) These sampling and analysis results do not include the annual monitoring required in paragraph (C)(2)(e) of rule 3745-3-03 of the Administrative Code.
(5) Resampling of a violation. Unless paragraph (G)(5)(c) of this rule applies, repeat sampling and analysis shall be performed within thirty days after the industrial user or control authority 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 the control authority 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 the control authority within thirty days after becoming aware of the violation.
(b) If sampling and analysis performed by the control authority under paragraph (G)(4) of this rule or paragraph (C)(2)(e) of rule 3745-3-03 of the Administrative Code indicates a violation, the control authority shall perform the repeat sampling and analysis unless the control authority 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) The control authority performs sampling at the industrial user at a frequency of at least once per month.
(ii) The control authority 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.
(6) The reports required in paragraphs (B), (D), and (E) of this rule shall be conducted in accordance with all of the following:
(a) The reports shall be based upon data obtained through appropriate sampling and analysis performed during the period covered by the report, which data is representative of conditions occurring during the reporting period.
(b) The control authority shall require that frequency of monitoring necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements.
(c) Grab samples shall be used for pH, hexavalent chromium, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds.
(d) 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 the control authority.
(e) Where time-proportional composite sampling or grab sampling is authorized by the control authority, the samples shall be representative of the discharge and the decision to allow the alternative sampling shall be documented in the industrial user file for that facility or facilities.
(f) 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:
(i) For hexavalent chromium, cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field.
(ii) For volatile organics and oil and grease the samples may be composited in the laboratory.
(iii) Composite samples for other parameters unaffected by the compositing procedures as documented in approved U.S. EPA methodologies may be authorized by the control authority, as appropriate.
(7) For the reports required by paragraph (E) of this rule, the control authority shall require the number of grab samples necessary to assess and assure compliance by industrial users with applicable pretreatment standards and requirements.
(8) If an industrial user subject to the reporting requirement in paragraph (E) of this rule monitors any regulated pollutant at the permitted sampling location more frequently than required by the control authority, using the procedures described in paragraph (G)(3) of this rule, the results of this monitoring shall be included in the report.
(9) The control authority 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.
(H) All industrial users shall promptly notify the control authority and the POTW in the cases where the POTW does not have an approved pretreatment program in advance of any substantial change 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 C.F.R. 403.12(p). Industrial users shall notify the POTW immediately of any changes at the facilities affecting potential for a slug discharge.
(I) Annual certification by non-significant categorical industrial users. In addition to the certification statement in paragraph (F)(1) of this rule, a facility determined to be a non-significant categorical industrial user pursuant to paragraph (N) of rule 3745-3-01 of the Administrative Code shall annually submit the following certification statement, signed in accordance with the signatory requirements in paragraph (F) of this rule. The following certification shall accompany any report required by the POTW:
"Based on my inquiry of the person or persons directly responsible for managing compliance with the categorical pretreatment standards under 40 C.F.R.
