14.2 Environmental Protection, NPDES Stormwater & Asbestos / Lead
Key Takeaways
Florida's NPDES Generic Permit for Stormwater Discharge from Large and Small Construction Activities (CGP) regulates construction activities disturbing 1 or more acres of land, or smaller sites part of a larger common plan of development.
The responsible operator must develop a site-specific SWPPP and submit a complete NOI and permit fee to FDEP at least 2 calendar days before commencing soil-disturbing activities.
Qualified inspectors must conduct SWPPP inspections at least once every 7 calendar days and within 24 hours of any rainfall event measuring 0.50 inches or greater.
Under the Asbestos NESHAP and FDEP rules, contractors must submit written notification at least 10 working days prior to demolition or renovation involving regulated asbestos-containing material (RACM) meeting statutory threshold quantities.
The EPA Renovation, Repair, and Painting (RRP) Rule mandates lead-safe work practices, firm certification, and certified renovators for pre-1978 target housing and child-occupied facilities, with 3-year record retention requirements.
14.2 Environmental Protection, NPDES Stormwater & Asbestos / Lead
Exam Focus: Environmental compliance on Florida construction projects is governed by overlapping federal EPA standards and Florida Department of Environmental Protection (FDEP) rules. Key examination areas include National Pollutant Discharge Elimination System (NPDES) Construction Generic Permit rules, Stormwater Pollution Prevention Plan (SWPPP) implementation, Asbestos NESHAP notification thresholds, and EPA Lead Renovation, Repair, and Painting (RRP) mandates.
Florida NPDES Stormwater Construction Generic Permit (CGP)
Under Section 402 of the Federal Clean Water Act and F.A.C. Rule 62-621.300(4)(a), qualifying construction activity that discharges stormwater to surface waters of the state, directly or through an MS4, requires NPDES authorization.
Regulatory Disturbance Thresholds
Coverage under the Florida Generic Permit for Stormwater Discharge from Large and Small Construction Activities (CGP) is mandatory for:
- Any construction project that disturbs one (1) or more acres of total land area.
- Projects disturbing less than one acre of land if the activity is part of a "larger common plan of development or sale" that ultimately disturbs one or more cumulative acres (such as an individual half-acre commercial outparcel inside a master planned retail center).
Permitting Process and Notice of Intent (NOI)
To obtain CGP authorization, the operator—the entity with authority to control the construction activities needed for permit compliance—completes the following steps. The operator may be an owner, contractor, public organization, or other legal entity; it is not automatically the general contractor:
- Prepare SWPPP: Complete a site-specific Stormwater Pollution Prevention Plan before filing for permit coverage.
- Submit Notice of Intent (NOI): Submit FDEP Form 62-621.300(4)(b) electronically through the FDEP Business Portal along with the required statutory application fee ($250 for projects disturbing between 1 and 5 acres; $400 for projects disturbing 5 or more acres).
- Filing Timeline: The NOI and fee must be submitted at least 48 hours prior to commencing any soil-disturbing construction activity (clearing, grubbing, grading, or excavating).
- Coverage Duration: CGP permit coverage remains effective for a term of up to five (5) years.
Stormwater Pollution Prevention Plan (SWPPP) & Best Management Practices
The Stormwater Pollution Prevention Plan (SWPPP) is a living technical document that details site hydrology, potential pollutant sources, and engineering controls designed to prevent soil erosion and retain sediment on site. The SWPPP must be retained directly on the active construction jobsite at all times from initial ground disturbance until final site stabilization.
Best Management Practices (BMPs) Categories
Erosion and sediment controls implemented under an SWPPP are divided into structural and operational Best Management Practices:
| BMP Classification | Control Mechanism | Operational Function & Placement |
|---|---|---|
| Structural Controls | Silt Fences | Geotextile fabric trenched into the soil along downslope site perimeters to filter sediment out of sheet flow. |
| Structural Controls | Sediment Basins / Traps | Engineered impoundment areas designed to slow runoff velocity, allowing suspended soil particles to settle before discharge. |
| Structural Controls | Turbidity Barriers | Floating geotextile curtains deployed directly in adjacent wetlands, canals, or open water bodies to confine suspended sediment. |
| Structural Controls | Storm Drain Inlet Protection | Fabric drops, gravel bags, or block-and-gravel filters placed around curb inlets and catch basins to catch sediment. |
| Operational Controls | Stabilized Construction Entrance | Aggregate, tire wash, or another SWPPP-selected control sized and maintained for site traffic and soil conditions; the Florida CGP requires control of off-site tracking but does not prescribe a universal 50-foot-by-6-inch entrance. |
| Operational Controls | Phased Clearing & Mulching | Minimizing exposed soil by stripping ground in stages; applying temporary seed, straw mulch, or soil tackifiers within 7 days of grading cessation. |
| Operational Controls | Concrete Washout Enclosures | Impervious, lined pits or prefabricated containers for cleaning mixer chutes, preventing caustic cement wash from entering groundwater. |
SWPPP Inspection Protocols and Notice of Termination (NOT)
Routine surveillance and maintenance of erosion controls are strict legal requirements under the Florida CGP.
Mandatory Inspection Schedule
Inspections must be performed by a qualified inspector. The CGP accepts a person who completed the DEP inspector program, completed equivalent formal training, or is qualified through other training or practical experience in stormwater pollution prevention and erosion/sediment control; professional engineering licensure is not the only alternative:
- Weekly Frequency: Conducted at least once every seven (7) calendar days.
- Rainfall Event Trigger: Conducted within 24 hours of the end of any rainfall event producing 0.50 inches or greater of precipitation.
- Rain Gauge Protocol: The contractor must maintain a calibrated rain gauge on site, or record daily rainfall data from a verified local National Weather Service reporting station.
Inspection Logs and Corrective Action Timelines
Each inspection requires a written report documenting the inspection date, rainfall measurement, condition of outfalls and receiving waters, and operational status of all BMPs. If an inspector identifies failing, compromised, or damaged controls (such as a fallen silt fence or filled sediment trap):
- Corrective actions and any needed SWPPP/control revisions must be completed in a timely manner and no later than seven (7) calendar days after the inspection or identification of the issue.
- The site log contains the NOI, coverage acknowledgment, SWPPP, inspection reports, records, and DEP notifications. Records must be retained for three years from final stabilization and NOT submission.
Notice of Termination (NOT) and Final Stabilization
Permit obligations do not cease when building construction concludes. The contractor remains legally liable for stormwater discharges until formal permit termination:
- Final Stabilization Requirement: All soil-disturbing activities must be complete, and unpaved areas not covered by permanent structures must have uniform perennial vegetative cover with at least 70% density or equivalent permanent stabilization. The current Florida CGP states a 70% density standard, not “70% of native background.”
- Filing NOT: The operator must submit a Notice of Termination (NOT) using the current FDEP Notice of Termination form identified under Rule 62-621.300(6) within 14 calendar days after achieving verified 70% final stabilization.
Asbestos NESHAP Regulations & Florida DEP Rules (40 CFR Part 61 & F.A.C. 62-257)
The federal Clean Air Act regulates asbestos emissions under the National Emission Standards for Hazardous Air Pollutants (NESHAP), codified in 40 CFR Part 61, Subpart M, and enforced across Florida through FDEP and Chapter 62-257 of the Florida Administrative Code.
Mandatory Pre-Work Inspection
Prior to initiating any demolition or renovation work on a commercial structure, institutional building, or multi-family residential property with more than four dwelling units, the facility owner or contractor must have a thorough inspection conducted by an accredited Florida licensed asbestos consultant to identify all Regulated Asbestos-Containing Material (RACM), regardless of the construction date of the building.
Threshold Triggers and Mandatory Written Notification
Written notification must be submitted to FDEP or the local county environmental protection agency using FDEP Form 62-257.900(1) at least ten (10) working days (excluding weekends and legal holidays) prior to initiating:
- Any demolition project, even when no asbestos is present in the facility.
- Any renovation project disturbing RACM that equals or exceeds the statutory threshold quantities:
- 160 square feet on facility components (such as wallboard, flooring, or ceiling materials);
- 260 linear feet on pipes; or
- 35 cubic feet off facility components where the area or length could not previously be measured.
RACM includes friable asbestos material (material containing greater than 1% asbestos that can be crumbled by hand pressure) and non-friable Category I or II materials that have become pulverized or subjected to sanding, grinding, or abrasive cutting. Asbestos abatement work in Florida must be performed by a licensed Asbestos Abatement Contractor licensed under Florida Statutes Chapter 469.
EPA Renovation, Repair, and Painting (RRP) Rule (40 CFR Part 745)
The EPA Lead Renovation, Repair, and Painting (RRP) Rule protects occupants and workers from hazardous lead dust generated during construction activities.
Statutory Applicability
The RRP Rule applies to any paid contractor, painter, carpenter, or window installer performing work that disturbs painted surfaces in:
- Target Housing: Any residential dwelling constructed prior to 1978 (except zero-bedroom housing or housing designated for elderly persons where no child under age 6 resides).
- Child-Occupied Facilities: Any public or commercial building built before 1978 where children under age 6 regularly visit (such as daycares, preschools, and elementary classrooms).
Firm Certification and Certified Renovator Training
- Firm Certification: Contracting businesses performing covered renovations must apply to the EPA and obtain an official Lead-Safe Certified Firm credential.
- Certified Renovator: Each jobsite must have at least one designated Certified Renovator who has successfully completed an EPA-accredited 8-hour training course. The Certified Renovator trains workers, oversees work-area containment, and performs cleaning verification.
Prohibited Practices and Recordkeeping
The RRP Rule strictly bans dangerous work techniques that vaporize or disperse lead dust:
- Prohibited Work Methods: Open-flame burning or torching; heat guns operating at or above 1,100 degrees Fahrenheit; and operating power tools (sanders, grinders, planers) without an attached HEPA-exhaust vacuum shroud.
- Mandatory Lead-Safe Work Practices: Heavy-duty plastic sheeting must extend at least 6 feet beyond work perimeters for interior renovations and at least 10 feet for exterior renovations.
- Record Retention: Contractors must retain all signed pre-renovation education acknowledgment receipts (distributing the EPA "Renovate Right" pamphlet), certified renovator certificates, and post-work cleaning verification records for a minimum of three (3) years.
