NOTICE IS HEREBY GIVEN that on October 20, 2006, the Department of Environmental Protection has issued an order.

The final order in OGC Case No.03-0656 granted variances from or waivers of paragraphs 62-610.563(3)(d), (e) and (f), 62-610.563(6)(c), Rule 62-610.564, subsections 62-610.567(2), 62-610.568(4), paragraphs 62-610.568(5)(a) and (b), subsections 62-610.568(7), 62-610.571(1), 62-610.573(3), and 62-610.574(3), F.A.C. to Destin Water Users, Inc. The final order granted variances and waivers that are permanent and are conditioned as follows:

1.If the Sand and Gravel Aquifer were ever used as a potable water supply by DWU, any wells constructed into the Sand and Gravel Aquifer within one mile of the proposed injection system would be treated with reverse osmosis or a higher treatment level prior to discharge into the DWU potable water system. Existing or future DWU potable wells within one mile of the proposed injection system shall not be required to have additional treatment if the wells are in the deeper Floridan Aquifer.

2.DWU proposes to construct the injection wells on property owned by DWU at the water reclamation facility and the Morgan Sports Complex. The wells will be located as centrally as possible on those parcels given the existing land use constraints. Both the water reclamation facility and Morgan Sports Complex sites are already developed. The wells would be constructed within close proximity to existing reclaimed water lines and the proposed well location must not interfere with the existing land use. Separate UIC construction and operation permits and a domestic wastewater permit revision will be obtained from the Department for the proposed injection wells.

3.DWU agrees to record deed restrictions on the water reclamation facility and Morgan Sports Complex properties that would prohibit the construction of potable wells into the Sand and Gravel Aquifer on those properties.

4.Subsection 62-610.567(2), F.A.C. DWU shall provide as part of the operating protocol developed under subsection 62-610.568(7), F.A.C., a detailed operating protocol that will address how the shallow well system will be taken off line if required water quality cannot be maintained. The fail safe mechanism in the protocol will include SCADA alarms and operator actions. Operator actions will include the diversion of flow to reject storage or the management of the water through other permitted facilities.

5.Subsection 62-610.568(4), F.A.C. TOC and TOX sampling and testing shall be conducted only during periods of injection. DWU shall sample and test once per injection period or once per injection week.

6.Paragraph 62-610.568(5)(a), F.A.C. DWU shall sample and test for total coliform each day of injection. DWU’s proposed wet weather injection system will be used on an infrequent basis and daily fecal coliform sampling and testing is already in place.

7.Paragraph 62-610.568(5)(b), F.A.C. DWU shall sample and analyze seven times in the first year the parameters listed as primary drinking water standards that are imposed as reclaimed water limits.

8.Subsection 62-610.568(7), F.A.C. Due to DWU’s variance from subsection 62-610.567(2), F.A.C., the operating protocol does not require fail safe “lock out” capability.

9.Subsection 62-610.571(1), F.A.C. The 500-foot setback distance from potable water supply wells is not required for DWU’s existing potable supply wells Nos. 2 and 3.

10.Subsection 62-610.573(3), F.A.C. DWU shall provide reject volume capacity equal to one day flow at the average daily design flow of the treatment plant or the average daily permitted flow of the reuse system, whichever is less.

Destin Water Users, Inc., construction and operation of the proposed injection well project, which was the subject of these variances and waivers, shall be authorized by future revision to wastewater permit (FLA010194) and a separate Underground Injection Control (UIC) permit.
