    RULE NO.:RULE TITLE:

    40C-8.031Minimum Surface Water Levels and Flows and Groundwater Levels

    PURPOSE AND EFFECT: The purpose and effect of the proposed rule amendment will be to add a reference to the equivalent North American Vertical Datum of 1988 (NAVD) elevation for the minimum surface water levels listed in subsections 40C-8.031(4) and (5), F.A.C., to reference those water levels in both the existing National Geodetic Vertical Datum of 1929 (NGVD) elevation and in the new NAVD elevation.

    SUMMARY: Adding a reference to the equivalent NAVD elevation for the minimum surface water levels in subsections 40C-8.031(4) and (5), F.A.C.

    SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS: The District has determined that this rule will not have an impact on small business and will not increase regulatory costs in excess of $200,000 within one year.  A SERC has not been prepared by the agency.

    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 the statement of estimated regulatory costs, or to provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice.

    RULEMAKING AUTHORITY: 373.044, 373.113 FS.

    LAW IMPLEMENTED: 373.042, 373.0421 FS.

    (5) The following minimum levels are established for Blue Cypress Water Management Area (BCWMA):

    (a) The minimum average level, calculated as the long term mean of BCWMA water levels, is 24.0 feet NGVD (22.5 feet NAVD). Water levels shall be at or above this level at least 75% of time over the long term.

    (b) The minimum frequent low is 23.0 feet NGVD (21.5 ft NAVD). The daily BCWMA water level shall not fall to this level or below more often than once every 2.5 years over the long term.

    (c) The minimum infrequent low is 22.5 feet NGVD (21.0 feet NAVD). The BCWMA water level shall not fall to this level or below for 60 continuous days more frequently than once every 10 years over the long term.

    (6) No change.

Summary:
Adding a reference to the equivalent NAVD elevation for the minimum surface water levels in 40C-8.031(4) and (5).
Purpose:
The purpose and effect of the proposed rule amendment will be to add a reference to the equivalent North American Vertical Datum of 1988 (NAVD) elevation for the minimum surface water levels listed in 40C-8.031(4) and (5) to reference those water levels in both the existing National Geodetic Vertical Datum of 1929 (NGVD) elevation and in the new NAVD elevation.
