  • 1(1) Existing manufacturing, commercial, mining, and silvicultural wastewater facilities or activities that discharge into surface waters shall notify the Department as soon as they know or have reason to believe:

    31(a) That any activity has occurred or will occur which would result in the discharge, on a routine or frequent basis, of any toxic pollutant which is not limited in the permit, if that discharge will exceed the highest of the following levels

    741. One hundred micrograms per liter,

    802. Two hundred micrograms per liter for acrolein and acrylonitrile; five hundred micrograms per liter for 2, 4-dinitrophenol and for 2-methyl-4, 6-dinitrophenol; and one milligram per liter for antimony,

The level established in the permit shall not exceed the technology-based treatment requirements appropriate to the permittee established in Chapter 62-660, F.A.C.

    287(2) All domestic wastewater facilities shall provide notice to the Department of the following:

    301(a) Any new introduction of pollutants into the facility from an industrial discharger which would be subject to Chapter 403, F.S., and the requirements of this chapter if it were directly discharging those pollutants; and

    336(b) Any substantial change in the volume or character of pollutants being introduced into that facility by a source which was identified in the permit application and known to be discharging at the time the permit was issued.

    374(3) The notice required by subsection (2) above shall include information on the quality and quantity of effluent introduced into the facility and any anticipated impact of the change on the quantity or quality of effluent to be discharged from the facility.

    416(4) Reuse systems permitted under Chapter 62-610, Part III, F.A.C., also must meet the requirements of subsections (2) and (3) of this section.

    439(5) Use of the parameter CBOD5 in lieu of BOD5 in effluent limitations for domestic wastewater facilities shall be in accordance with 46140 CFR 133.102(a)(4), 464unless a water quality based limitation for CBOD5 has been established for the discharge.

    478(6) Pursuant to Section 482403.0882, F.S., 484the Florida Legislature has determined that it is in the public interest to promote alternative water supplies and brackish water demineralization as an alternative to withdrawals of groundwater and surface water. Within subsection 51762-620.625(6), 518F.A.C., the terms “demineralization concentrate” and “concentrate” are used synonymously.

    528(a) The following provisions apply to all facilities that discharge demineralization concentrate, as defined in subsection 54462-620.200(11), 545F.A.C.:

    5461. During preliminary siting considerations, it is recommended that water supply utilities or entities that propose to operate demineralization facilities evaluate concentrate disposal options potentially available in the project area.

    5762. Discharge of demineralization concentrate shall not commence until an individual wastewater treatment facility or activity permit or permit revision authorizing the discharge has been issued by the Department in accordance with the requirements of this chapter.

    6133. Direct discharge of concentrate to waters shall require an individual wastewater facility permit under this Chapter using DEP Application Form 2DC Permit to Discharge Demineralization Concentrate, as referenced in subsection 64462-620.910(18), 645F.A.C.

    6464. Blending of concentrate with wastewater from a Department permitted wastewater facility for purposes of treatment or disposal shall require a separate permit for the concentrate discharge unless the receiving wastewater facility permit is revised in accordance with the requirements of subsection 68862-620.200(25) 689or (50), F.A.C., to incorporate all aspects of concentrate treatment or disposal and provide reasonable assurance that the discharge will meet applicable water quality standards.

    7145. Demineralization concentrate and reclaimed water may be blended, provided that the requirements in Rule 72962-610.865, 730F.A.C., Blending of Demineralization Concentrate with Reclaimed Water, are met. Requirements for permitting, monitoring, operation, and other activities associated with the concentrate, reclaimed water, and blending of demineralization concentrate with reclaimed water that impact water quality shall be in accordance with Rule 77262-610.865, 773F.A.C. If a single municipality or utility owns and operates both the water treatment facility that generates the concentrate and the domestic wastewater facility that produces the reclaimed water, a separate discharge permit is not required for the concentrate discharge facility, in accordance with paragraph 81862-610.865(7)(b), 819F.A.C. In this case, however, the domestic wastewater permit must be revised to incorporate all aspects of demineralization concentrate blending, in accordance with the requirements of Rule 84662-610.865, 847F.A.C.

    8486. A facility that discharges demineralization concentrate to ground water solely using underground injection wells for disposal shall not be required to obtain a permit under Chapter 62-620, F.A.C.

Requirements for toxicity monitoring shall be in accordance with paragraph 108762-620.625(6)(c), 1088F.A.C.

    10899.

    120711. If the result of a gross alpha particle activity analysis in demineralization concentrate effluent, or at a groundwater monitoring well, is less than 5 Picocuries/liter, analysis for radium 226 and 228 shall not be required for that sample.

    124612. Except as provided for small water utility businesses in paragraph 125762-620.625(6)(b), 1258F.A.C., demineralization concentrate discharges shall be monitored at the following frequencies:
