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.

Frequently Asked Questions

How much does it cost to file a Notice of Intent? expand_more
Filing fees vary by state but typically range from $100-500 for the NOI itself. However, the real cost comes from implementing required stormwater controls and ongoing compliance monitoring. Budget several thousand dollars for a typical commercial project when you include erosion control installation and maintenance.
What happens if I start construction without filing an NOI? expand_more
You'll face immediate regulatory violations that can shut down your project. EPA fines for unpermitted stormwater discharges start at $2,500 per day and can reach $25,000 daily for serious violations. State agencies add their own penalties on top of federal fines.
How long does NOI approval take? expand_more
Most states don't formally 'approve' NOIs. Instead, you're automatically covered under the general permit 14 days after filing, assuming your paperwork is complete. However, you should submit your NOI 30-45 days before construction to allow time for any required corrections or clarifications.
