PURPOSE AND EFFECT: The purpose and effect of the proposed rule amendment will be to create a new definition in 40C-8.021 and adopt a minimum water level for Lochloosa Lake in Alachua County in 40C-8.031.

SUMMARY: The proposed rules would define “P50” and establish a minimum water level for Lochloosa Lake pursuant to the mandate of Section 373.042, Florida Statutes. The terms herein are already defined in Chapter 40C-8, F.A.C. As with all minimum water level established by the District, if adopted, the minimum water level in this rule amendment would be used as a basis for imposing limitations on withdrawals of groundwater and surface water in the consumptive use permit regulatory process and for reviewing proposed surface water management systems in the environmental resource permit regulatory process.

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 has completed for the Governor’s Office of Fiscal Accountability and Regulatory Reform (OFARR) the “Is a SERC Required?” form and prepared a summary of the proposed rule amendments, which are both available upon request. Based on the completed “Is a SERC Required?” form and summary and the analysis performed by the District in preparing and completing those documents, the proposed rule amendments are not expected to require legislative ratification pursuant to subsection 120.541(3), F.S.

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.

The minimum P50 level for Lochloosa Lake is a long-term median lake level based on the MFLs condition lake level time series (1957 – 2015), effective {effective date}, which is incorporated by reference and available at {insert URL} and upon request from the St. Johns River Water Management District, 4049 Reid Street, Palatka, FL 32177-2529.

 

MFL status of Lochloosa Lake will be assessed by comparing the minimum P50 to the current P50. The current P50 for Lochloosa Lake is calculated by updating the simulated historical lake level time series (1957 – 2015) with post-2015 observed data at SJRWMD gage 71481615. The simulated historical lake level time series is incorporated by reference and available at {insert URL} and upon request from the St. Johns River Water Management District, 4049 Reid Street, Palatka, FL 32177-2529.
