(a) The city, through its employees, is authorized to inspect the facilities of any user to ascertain whether the purpose of this chapter is being met and all requirements are being complied with. Persons or occupants of premises where wastewater is created or discharged shall allow the city or its representative ready access at all reasonable times to all parts of the premises for the purposes of inspection, sampling, records examination, records copying, or in the performance of their duties. The city, WWF, state DEP, and EPA shall have the right to set up on the user's property those devices as are necessary to conduct sampling inspection, compliance monitoring, or metering operations. Where a user has security measures in force which would require proper identification and clearance before entry into their premises, the user shall make necessary arrangements with their security guards so that upon presentation of suitable identification, personnel from the city, WWF, DEP, and EPA will be permitted to enter, without delay, for the purposes of performing their specific responsibilities (also see Section 26-168). Penalty, see Sec. 26-177.
(b) 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 requirements of 40 CFR Part 136, Chapter 62-160, F.A.C, and Rule 62-625.600(6)(d) and (e), unless otherwise specified in an applicable categorical pretreatment standard. If 40 CFR Part 136 does not contain appropriate sampling or analytical techniques for the pollutant in question, the laboratory, with approval of the industrial user, the City and FDEP, shall identify and propose a method for use in accordance with Rules 62-160.300 and 62-160330, F.A.C
(c) Sample Collection. Except as indicated in subsection (1) below, the user must collect wastewater samples using 24-hour flow proportional composite collection techniques. In the event flow proportional sampling is not feasible, the Director may authorize, in writing, the use of time proportional sampling or a minimum of four (4) 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. The City shall require the number of grab samples necessary to assess and assure compliance by industrial users with the applicable pretreatment standards and requirements. Sample collection shall meet the requirements of Rule 62-625.600(6)(c)-(f), F.A.C.
(1) Samples for oil and grease, temperature, pH, cyanide, phenols, sulfides, and volatile organic compounds must be obtained using grab sample techniques.
(2) All samples shall be representative of daily operations. Both daily maximum and average concentration (or mass, where required) shall be reported. In cases where the pretreatment standard requires compliance with a best management practice or pollution prevention alternative, the industrial user shall submit documentation as required by the City or the applicable standards to determine compliance with the standard.
(3) Samples shall be taken immediately downstream from pretreatment facilities, if such exist, or immediately downstream from the regulated process if no pretreatment exists. If other wastewaters are mixed with the regulated wastewater prior to pretreatment, the industrial user shall measure flows and concentrations necessary to allow use of the combined waste stream formula of Rule 62-625.410(6), F.A.C., in order to evaluate compliance with the pretreatment standards. Where an alternate concentration or mass limit has been calculated in accordance with Rule 62-625.410(6), F.A.C., this adjusted limit, along with supporting data, shall be submitted to the City.
