Several basin and flood studies are available for viewing at the Public Works Administration offices located at 323 N. Sinclair Ave, Tavares. Please see list of available studies on the Stormwater Study Request form.

National Pollutant Discharge Elimination System (NPDES)

The National Pollutant Discharge Elimination System (NPDES) stormwater permit program was created pursuant to the Federal Clean Water Act. The NPDES program regulates point source discharges from three potential sources: Municipal Separate Storm Sewer Systems (MS4s), construction activities and industrial activities. In 2000, the EPA delegate authority to the Florida Department of Environmental Protection to administer the NPDES program within the State.

As an operator of an MS-4, Lake County is required to obtain a NDPES permit. This permit is good for five years and requires annual reporting to the State on permit required activities intended to reduce stormwater pollution. Lake County was issued its first NPDES MS-4 permit in 2005 and is currently in the third cycle of permitting. This permit covers the un-incorporated portions of Lake County. Each Municipality within Lake County has their own NPDES permit for the stormwater system within their jurisdiction.

The Stormwater Section has completed the permit Cycle 3 Year 4 Report. This report quantifies the required activities in stormwater pollution reduction the County has completed for the reporting period. A copy of the report is available for public inspection during normal business hours at the Public Works Administration Office located at 323 N. Sinclair Ave, Tavares FL, 32778.

The Federal Environmental Protection Agency has additional NPDES program information available at their website: https://www.epa.gov/npdes.

Lake County's NPDES permit requires the implementation of an Illicit Discharge Detection and Elimination program. This program is designed to prohibit non-stormwater discharges from entering the County storm sewer system. Stormwater Section staff conduct ongoing inspections and outreach efforts to targeted industries regarding Illicit Discharge, this includes outreach to automotive service, restaurant and landscape service business.

The Illicit Discharge Detection and Elimination Manual is a resource utilized to train personnel on how to recognize an Illicit Discharge and how to report the discharge.

With the exception of a few common sense discharges, such as residential car washing, fire line flushing, irrigation water and pumped ground water, the only thing that should go down a storm drain is rain water. Lake County has implemented a storm drain awareness and marking campaign of "Only Rain Down the Storm Drain".

If you suspect and illicit discharge to the County’s stormwater system, please contact the Lake County Stormwater Section at 352-253-9080 or via email at stormwater@lakecountyfl.gov.

Basin Management Action Plans (BMAPS)

A Basin Management Action Plan (BMAP) is the "blueprint" for restoring impaired waters by reducing pollutant loadings to meet the allowable loadings established in a Total Maximum Daily Load (TMDL). It represents a comprehensive set of strategies - permit limits on wastewater facilities, urban and agricultural best management practices, conservation programs, financial assistance and revenue generating activities that are intended to implement the pollutant reductions established by the TMDL. These broad-based plans are developed with local stakeholders and are adopted by order of the Secretary of the Department of Environmental Protection.

Lake County has three (3) BMAPs within the County:
