(A) Any IU subject to a categorical pretreatment standard, after the compliance date of that pretreatment standard or, in the case of a new source, after commencement of the discharge into the WWF, shall submit to the director during the months of June and December, unless required more frequently in the pretreatment standard or by the director, a report indicating the nature and concentration of pollutants in the discharge which are limited by such categorical pretreatment standards, and a reasonable measure of the IU's long-term production rate. If an IU is subject to categorical standards with only production-based limits, actual average production rate data for the reporting period must be given. In addition, this report shall include a record of measures or estimated average and maximum daily flows for the reporting period for the discharge reported in § 54.101(B)(4) except that the director may require more detailed reporting of flows. At the discretion of the director and in consideration of such factors as the local high or low flow rates, holidays, budget cycles, etc., the director may agree to alter the months during which the above reports are to be submitted. In cases where the pretreatment standard requires compliance with a Best Management Practice (BMP) or pollution prevention alternative, the IU must submit documentation required by the director or the pretreatment standard necessary to determine the compliance status of the IU.
(B) All wastewater samples must be representative of the IU'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 an IU to keep its monitoring facility in good working order shall not be grounds for the IU to claim that sample results are unrepresentative of its discharge.
(C) If an IU subject to the reporting requirement in this section monitors any pollutant more frequently than required by the director using the procedures prescribed in § 54.113, the results of this monitoring shall be included in the report.
(D) Periodic compliance 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. The director shall require that frequency of monitoring necessary to assess and assure compliance by IUs with applicable pretreatment standards and requirements.
(E) All periodic compliance reports must be signed and certified in accordance with § 54.114.
(F) The city may authorize the IU subject to a categorical pretreatment standard to waive sampling of a pollutant regulated by a categorical pretreatment standard if the IU demonstrates the following through sampling and other technical factors:
(1) The pollutant is neither present nor expected to be present in the discharge, or the pollutant is present only at background levels from intake water and without any increase in the pollutant due to activities of the IU; and
(2) The 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.
(G) This authorization of the monitoring waiver is subject to the following conditions and does not supersede certification processes and requirements established in categorical pretreatment standards, except as specified in the categorical pretreatment standard:
(1) The monitoring waiver is valid only for the duration of the effective period of the IU permit, and in no case longer than five years. The IU must submit a new request for the waiver before the waiver can be granted for each subsequent control mechanism.
(2) In making a demonstration that a pollutant is not present, the IU must 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 FDEP-approved method from 62-4.246, F.A.C, with the lowest method detection limit for that pollutant was used in the analysis.
(3) The request for a monitoring waiver must be signed in accordance with § 54.114 below including the certification statement.
(4) The authorization will be included as a condition in the IU's permit. The reasons supporting the waiver and any information submitted by the IU in its request for the waiver will be maintained by the control authority for three years after expiration of the waiver.
(5) Upon approval of the monitoring waiver and revision of the IU's permit by the control authority, the IU must certify each report with the following statement: "Based on my inquiry of the person or persons directly responsible for managing compliance with the pretreatment standard for 40 CFR [specify applicable national pretreatment standard part(s)], I certify that, to the best of my knowledge and belief, there has been no increase in the level of [list pollutant(s)] in the wastewaters due to the activities at the facility since filing of the last periodic report under § 54.104(A), of City of Mexico Beach Code of Ordinances."
(6) 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 IU's operations, the IU must immediately notify the control authority and comply with the monitoring requirements of § 54.104(A) - (E) or other more frequent monitoring requirements imposed by the county.
