(1) General.
    (a) The Department uses the information submitted on Discharge Monitoring Reports required by part IV of this chapter to establish facility compliance, or noncompliance, with the treatment standards of this rule. For such evaluations, the appropriate reclaimed water or effluent concentrations contained in subsection 62-600.740(2), F.A.C., shall be used for compliance determinations.
    (b) The Department may also take enforcement action based on its own sample collection activities using any of the annual, monthly, weekly, or maximum-permissible concentrations specified in subsection 62-600.740(2), F.A.C. Use of such data shall not preclude enforcement action pursuant to the provisions of this or any other chapter of the Florida Administrative Code. The use of grab or composite samples for evaluating annual, monthly or weekly compliance shall be consistent with grab or composite sampling technique (as opposed to sample scheduling) requirements of part IV of this chapter.
    (c) Nothing in this or any other rules of the Florida Administrative Code shall preclude the use, by the Department, of additional or more representative sampling data in establishing compliance status.
    (2) Reclaimed Water or Effluent Compliance Concentrations.
    (a) Compliance of a domestic wastewater facility with secondary treatment standards shall be determined in accordance with Fl. Admin. Code R. 62-600.420
    (b) In order to determine compliance of a domestic wastewater facility with treatment standards more stringent than secondary such as Advanced Waste Treatment (Florida Statutes § 403.086), WQBELs (i.e., Fl. Admin. Code R. 62-600.430), and certain reuse systems (i.e., Fl. Admin. Code Chapter 62-610), the following compliance concentrations shall be applicable.
    1. The annual average pollutant value shall not exceed the design concentration established for the reclaimed water or effluent.
    2. The monthly average pollutant value shall not exceed one and one-quarter times the design concentration for the reclaimed water or effluent.
    3. The weekly average pollutant value shall not exceed one and one-half times the design concentration specified for the reclaimed water or effluent.
    4. The maximum-permissible pollutant concentration in any single sample shall not exceed two times the design concentration specified for the reclaimed water or effluent.
    (c) In order to determine compliance of a domestic wastewater facility with the alternative secondary preapplication treatment standards specified in Part VI of Fl. Admin. Code Chapter 62-610, the design criteria specified therein shall apply as compliance concentrations at all times (i.e., the design criteria applies on an annual, monthly, weekly, and maximum-permissible concentration basis). Other compliance concentrations in this section shall be applicable upon release of the effluent from operational control in order to determine compliance with other requirements of this chapter.
    (d) In order to determine compliance of a domestic wastewater facility with disinfection criteria (other than the basic level) specified in subsection 62-600.440(4), F.A.C., for outfalls discharging to open ocean waters, the disinfection level approved by the Department shall apply as compliance concentrations at all times (i.e., the design criteria applies on an annual, monthly, weekly, and maximum-permissible concentration bases).
    (3) Biosolids compliance criteria shall be in accordance with the applicable portions of Fl. Admin. Code Chapter 62-640
