Summary
Polk County's Stormwater Quality Management Ordinance bars discharges that impair the county's storm sewer system or pollute receiving waters, and requires anyone responsible for an impairing discharge to fix it on a county-approved schedule. It covers unincorporated Polk County and every municipality's storm sewer system within the county.
(a)The discharge of stormwater to an MS4 shall be controlled to the extent that such discharge will not impair the operation of the MS4 or contribute to the failure of the MS4 to meet any state or federal requirements. Discharges to waters of the United States shall be controlled to the extent that the discharge will not adversely impact the quality or beneficial uses of the receiving water.(b)Any person responsible for stormwater discharges determined by the municipality to be contributing to the impairment of waters of the U.S., either directly or through an MS4, shall provide corrective measures in accordance with a schedule approved by the municipality.

Full Breakdown
Polk County Code Sec. 26 require local legal authority to control MS4 discharges under the NPDES program. Sec. 12-149 applies the article to all unincorporated areas and to the corporate limits of every Polk County municipality, though a municipality's own conflicting ordinance takes precedence within its limits. The core operative rule, Sec. waters, directly or through an MS4, must provide corrective measures on a schedule approved by the municipality. Sec. 12-153 extends the same no-impairment standard to discharges passed between interconnected MS4 systems, making the owner of each segment responsible for the quality leaving that segment and requiring coordination with downstream owners before modifying the system.
Sec. waters unless it falls under the Sec. water quality standards, NPDES-permitted discharges, and properly labeled fertilizer, pesticide or herbicide use. Sec. 12-157 and 12-158 give municipal personnel inspection access to facilities discharging to an MS4 and require structural BMPs to be maintained to their original design performance.
Violations & Fines
Sec. 12-161 lets the county issue a citation under the Polk County Citation Ordinance (No. 92-32) or prosecute violators before the county or municipal code enforcement board, with each day of noncompliance a separate violation. A person may also be prosecuted under Section 125.69, Florida Statutes, with each day of violation punishable by up to a $500 fine, up to 60 days in the county jail, or both. Violators are additionally liable for all sampling and analytical costs, any state or federal fines triggered by the discharge, and the full cost of restoring the receiving waters, and the county attorney can seek a circuit court injunction plus court-ordered restoration and mitigation.
