Illicit Discharge Prevention Consulting
Industrial facilities operate under some of the most stringent environmental regulations in the country β and for good reason. When non-stormwater pollutants like process wastewater, equipment wash water, oils, and chemicals enter a storm drain, they flow directly into Florida's rivers, lakes, and coastal waters with no treatment. That is what makes illicit discharge one of the most serious β and most preventable β compliance risks an industrial facility faces. Florida's FDEP, authorized by the EPA under the NPDES program, actively monitors and enforces illicit discharge violations, and non-compliance can result in significant fines and legal consequences. This training program provides your team with the practical knowledge to identify discharge risks on the ground, implement the right prevention controls, meet Florida's Discharge Monitoring Report requirements, and keep your facility inspection-ready at all times. Because when it comes to illicit discharge, what your team doesn't know can cost you far more than training ever will.
Illicit
Discharge
Prevention
Practical instruction focused on identifying risks, preventing non-compliant discharges, and maintaining alignment with current Florida water quality standards. An illicit discharge is any non-stormwater discharge into a storm sewer system β and it is prohibited under Florida's NPDES program. This training equips your team to recognize, prevent, and report it.
What Is an Illicit Discharge β and Why Is It a Problem?
Federal regulations define an illicit discharge as any discharge to a storm sewer system that is not composed entirely of stormwater. Industrial facilities are among the highest-risk sources β and Florida's FDEP enforces violations aggressively.
Direct water quality harm
Illicit discharges introduce industrial pollutants β oils, chemicals, heavy metals, wash waters β directly into storm drains and waterways that receive no treatment before reaching rivers, lakes, and coastal waters.
NPDES permit violation
Any discharge in violation of an NPDES permit constitutes an illicit discharge. FDEP was authorized by the EPA in 2000 to enforce these requirements across Florida β with real penalties for non-compliance.
Dry weather discharges
Illicit discharges are most easily identified during dry weather β when any measurable flow at a stormwater outfall is a red flag. Regular dry weather screening is a core requirement of Florida's IDDE program.
Industrial facilities are priority targets
Commercial and industrial areas are identified by IDDE programs as having the highest number of illicit connections and greatest potential to impact water quality β making them inspection priorities.
Common Sources of Illicit Discharge at Industrial Facilities
Your team must be able to recognize these discharge sources before they reach a storm drain. Awareness is the first line of defense.
Process wastewater
Industrial process water discharged to storm drains instead of sanitary systems or permitted outfalls
Equipment wash water
Vehicle and equipment cleaning operations draining to uncontained areas connected to storm sewer
Spills & leaks
Uncontrolled releases of oils, fuels, chemicals, or solvents that reach storm drain inlets
Illegal dumping
Unauthorized disposal of liquids or waste into storm drains, ditches, or drainage channels
Sanitary wastewater
Cross-connections or overflows from sanitary systems entering the storm sewer network
Coolant & hydraulic fluid
Machinery fluids routed or leaked into drainage areas without adequate secondary containment
Paint & solvent washout
Washout from painting operations, cleaning solvents, or chemical mixing areas draining improperly
Contaminated stormwater
Runoff from uncovered material storage, loading docks, or processing areas carrying pollutants offsite

6 Steps to NPDES Industrial Discharge Compliance in Florida
Per FDEP's NPDES program for industrial stormwater discharges, every covered facility must follow these steps to remain compliant with Florida water quality standards.
Obtain the right NPDES permit
Secure permit coverage specific to your industrial sector under Florida's MSGP or obtain an individual permit under Rule 62-620 F.A.C. if ineligible for the generic permit.
Monitor discharge quality & quantity
Conduct regular monitoring of stormwater discharges including quarterly visual monitoring and benchmark analytical sampling as required by your permit sector.
Maintain accurate records
Keep complete documentation of all monitoring data, inspection reports, corrective actions, and DMRs on-site and accessible to authorized inspectors for a minimum of three years.
Implement BMPs
Deploy and maintain best management practices that minimize pollutant exposure to stormwater β covering storage, handling, containment, housekeeping, and spill prevention across all facility operations.
Submit DMRs on time
File required Discharge Monitoring Reports to FDEP on schedule as specified in your permit. Late or missing submissions are compliance violations even when discharge quality meets standards.
Stay current on regulations
Monitor updates from FDEP and EPA on changes to NPDES requirements, water quality standards, and permit conditions. Rule 62-621.300 F.A.C. was updated as recently as December 2024.

- Reputational damage and loss of business contracts
Illicit Discharge Detection and Elimination is one of the six Minimum Control Measures required under EPA's NPDES Phase II program β and Florida's FDEP actively enforces it. Non-compliance can result in significant fines and serious legal consequences. Knowing violations can also result in criminal prosecution.
