Collier County, FL Environmental Rules: Stormwater Management (2026)

Sec. 3 applies to any facility, industrial, commercial, residential or construction, whose stormwater discharges enter the Collier County municipal separate storm sewer system (CCMS4), and it triggers when permit requirements aren't met or reasonable Best Management Practices (BMPs) aren't implemented. If a private stormwater management system (Private SMS) feeds into a CCMS4 segment that FDEP has declared impaired, that lies upstream of an impaired waterbody, or whose downstream waterbody carries an adopted TMDL, BMAP or SSAC, Collier County Pollution Control can require the discharger to monitor water quality at the relevant outfall and, if needed, reduce the pollutant load being discharged to the greatest extent possible.

Enforcement runs through Sec. , Monday through Friday, to check compliance with permits, consent orders and BMPs, and can obtain an inspection warrant if access is refused. Sec. 8 requires anyone responsible for a discharge to report it to Pollution Control, remediate within a reasonable timeframe, and amend BMPs to prevent recurrence; the county can also order temporary disconnection of water service where an unmitigated illicit discharge threatens public health. Sec. 9 ties any associated fees to the Land Development Code's Growth Management Department fee schedule.

This water-pollution article sits in Chapter 54, Article III, apart from the separate Stormwater Utility article (Sec. ), which only governs utility billing and enterprise-fund fees, not discharge conduct.
