§ 118-14. Protection of Freshwater Lenses.

(a)

No new water supply wells, including but not limited to domestic water supply wells (for drinking, bathing, eating, cooking or sanitation) and irrigation wells, shall be installed in areas that have a discernible groundwater freshwater lens.

(b)

Existing water supply wells, including but not limited to domestic water supply wells and irrigation wells that are within a discernible groundwater freshwater lens shall be properly abandoned by pressure-grouting from bottom to top with neat cement grout in accordance with plugging requirements described in FDEP Chapter 62-532.500(4), F.A.C. Abandonment must be completed prior to issuance of any building permits or modifications for the property.

(c)

Chemicals that have a groundwater cleanup target level in Chapter 62-777, F.A.C., shall be protected from entering a groundwater freshwater lens by the following restrictions on lands overlying a discernible groundwater freshwater lens:

(1)

Production of these chemicals is prohibited.

(2)

Storage, handling, and use of these chemicals shall be solely for the onsite maintenance or operation of the business or residence. Commercial storage, commercial handling, or commercial use of these chemicals to serve offsite facilities is prohibited.

(3)

These chemicals shall be stored, handled, and used only in accordance with the manufacturer's instructions.

(4)

These chemicals shall be stored solely in original consumer packages in which they are typically distributed for consumer or commercial use, or in other suitable containers properly labeled so as to indicate their contents.

(5)

Liquids that contain these chemicals shall be stored with secondary containment. Secondary containment shall be an impermeable coating, membrane, surface, or structure in which tanks or containers are placed. For tanks or containers larger than 110 gallons, the secondary containment shall hold at least 110% of the volume of the largest tank or container. For tanks or containers of one (1) to 110 gallons, the secondary containment shall hold at least twenty percent (20%) of the combined volume of all the tanks or containers within the secondary containment, but no less than the volume of the single largest tank or container. A double-walled tank is considered secondary containment. All materials in a secondary containment shall be stored in a manner which, in the event of a release, prevents contact of the chemicals with soil, groundwater, or surface water.

(6)

Buildings that contain these chemicals shall have no floor drains or outlets, except those plumbed to a sanitary sewer system.

(7)

Release of these chemicals in any quantity on soils, in groundwater, or in surface waters is prohibited except when used according to the manufacturer's instructions, including but not limited to, the quantity and frequency of application.

(8)

Untreated water that contains these chemicals in concentrations above groundwater cleanup target levels shall not be released to the soil, groundwater, or surface water.

(9)

All waste products and containers containing these chemicals shall be properly disposed of in accordance with federal, state, and county requirements.
