RULE NO.:RULE TITLE:

40D-8.624Guidance and Minimum Levels for Lakes

PURPOSE AND EFFECT: The purpose of this rulemaking is to adopt revised minimum and guidance levels for Dosson Lake and Sunshine Lake located in Hillsborough County. The effect of the rule is to support the District’s water supply planning, water use permitting, and environmental resource permitting programs.

SUMMARY: Section 373.042, F.S., requires the District to establish minimum flows and levels for lakes, wetlands, rivers and aquifers within the District’s boundaries. Section 373.0421(3), F.S., further requires the District to periodically reevaluate and revise adopted minimum flows and levels. This rulemaking is necessary to adopt new guidance and minimum levels for Dosson Lake and Sunshine Lake located in Hillsborough County. The establishment and periodic evaluation of minimum levels is required by statute to ensure that the minimum hydrologic requirements of the water resources and ecology of these lakes are maintained. The revised minimum and guidance levels for Dosson Lake and Sunshine Lake are being developed using previously peer-reviewed, Governing Board adopted methods.

SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS AND LEGISLATIVE RATIFICATION:

The Agency has determined that this will not have an adverse impact on small business or likely increase directly or indirectly regulatory costs in excess of $200,000 in the aggregate within one year after the implementation of the rule. A SERC has not been prepared by the Agency.

The Agency has determined that the proposed rule is not expected to require legislative ratification based on the statement of estimated regulatory costs or if no SERC is required, the information expressly relied upon and described herein: The District conducted an economic review of the revisions to the rule and determined that the impact or regulatory cost, if any, of the revisions will not exceed any one of the economic analysis criteria in a SERC as set forth in Section 120.541(2)(a), F.S. The revised minimum levels for this lake is unlikely to constitute an additional significant regulatory constraint on groundwater or surface water withdrawals in the area due to existing resource conditions and regulatory constraints in the basin.

Any person who wishes to provide information regarding a statement of estimated regulatory costs, or provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice.
