NOI (Notice of Intent)
A Notice of Intent (NOI) is a legal document that must be filed with environmental agencies before beginning construction activities that disturb one or more acres of land. It's your permit application to discharge stormwater runoff under the National Pollutant Discharge Elimination System (NPDES) program.
What a Notice of Intent Actually Means
When you see NOI in a compliance report, it means someone needs to file paperwork before breaking ground. The Notice of Intent tells the EPA and state agencies that you’re planning construction work that could affect stormwater runoff. Think of it as giving officials a heads up before you start moving dirt around.
In South Carolina, Georgia, Florida, and North Carolina, you’ll typically file your NOI with the state environmental agency. They want to know what you’re building, how much land you’ll disturb, and what steps you’ll take to keep soil and pollutants out of nearby waterways.
Why Property Managers Need to Know This
If you’re overseeing any construction project larger than an acre, someone on your team needs to handle NOI filing. That includes parking lot expansions, building additions, market overhauls, or infrastructure improvements. Miss this step and you’re looking at serious fines.
The NOI isn’t just paperwork either. Filing it means you’re committing to follow a Stormwater Pollution Prevention Plan (SWPPP). You’ll need proper erosion control measures in place before work begins, and you’ll need to maintain them throughout construction.
Common Problems We See
Many property managers don’t realize their project needs an NOI until it’s too late. Others file the paperwork but don’t follow through with the required stormwater management practices. Both mistakes can shut down your project.
Another issue is timing. You need to file your NOI at least 14 days before construction starts in most states. File it too early, and you might need updates. File it too late, and you’re in violation before you begin.
State-Specific Requirements
South Carolina requires NOI filing through DHEC for the state’s NPDES program. Georgia handles theirs through EPD. Florida splits authority between DEP and local water management districts, depending on your location. North Carolina uses DEMLR for most NOI submissions.
Each state has slightly different forms and requirements, but they all want the same basic information: project details, site maps, contact information, and proof that you’ve developed a stormwater pollution prevention plan.
When to Call for Help
Don’t try to handle NOI requirements alone if you’re not familiar with environmental regulations. The paperwork might look straightforward, but the compliance requirements that follow are complex. Missing inspections, inadequate erosion controls, or improper storm drainage can trigger violations that cost far more than professional help.
We help property managers file NOIs correctly and maintain compliance throughout their projects. That means proper erosion controls, regular inspections, and documentation that keeps regulators happy.
Related Terms
Construction General Permit
A Construction General Permit (CGP) is a federal permit required for construction sites that disturb one acre or more of soil. It's issued under the Clean Water Act to prevent sediment and pollutants from construction activities from entering waterways during building projects.
National Pollutant Discharge Elimination System
NPDES (National Pollutant Discharge Elimination System) is a federal permit program that regulates what can be discharged into waterways. If your property has stormwater runoff, construction activities, or wastewater systems, you likely need NPDES permits and must follow specific water quality requirements.
Stormwater Pollution Prevention Plan
A Stormwater Pollution Prevention Plan (SWPPP) is a written document that identifies potential sources of pollution on your property and outlines specific steps to prevent contaminated stormwater from entering waterways during construction or industrial activities.
