Pro SWPPP – America’s #1 SWPPP Service helps construction teams across New Mexico stay compliant every single day. But here’s the deal: most people starting a project have no clue if they need a SWPPP, an NOI, or both. And if you get it wrong? Fines, delays, and headaches that cost you time and money. Let’s fix that right now.
What Is a SWPPP and Why Does New Mexico Care?
A Stormwater Pollution Prevention Plan (SWPPP) is your playbook for keeping dirt, chemicals, and trash out of streams, rivers, and lakes during construction. If you disturb one acre or more of land – or if your smaller site is part of a bigger plan – federal law under the Clean Water Act says you need one.
New Mexico follows the EPA’s National Pollutant Discharge Elimination System (NPDES) rules right now. That means if you’re digging, grading, or building, you need to show the EPA (and soon the state) how you’ll control stormwater runoff. The SWPPP lists your Best Management Practices (BMPs) – things like silt fences, erosion control blankets, and sediment basins – and keeps your site legal.
Think of it this way: no SWPPP means no permit. No permit means inspectors shut you down. Simple as that.
Do You Need a SWPPP in New Mexico?
Here’s the fast answer: if your construction project disturbs one acre or more, yes. If your project is smaller but part of a larger common plan – like a housing development or shopping center – you still need one.
Let’s break it down by project size:
- One acre or more: SWPPP required. Period.
- Less than one acre but part of a bigger plan: SWPPP required if the total plan disturbs one acre or more.
- Under one acre, standalone project: Usually no SWPPP, but you still need erosion control BMPs and a site notice posted.
- Projects in low rainfall areas: You might qualify for a Low Erosivity Waiver – but you still need to prove it with the EPA calculator.
New Mexico is in the middle of taking over permitting from the EPA. The New Mexico Environment Department (NMED) will run the New Mexico Pollutant Discharge Elimination System (NMPDES) soon. But until that switch happens, you still follow EPA rules and submit your paperwork to them.

What About the Notice of Intent (NOI)?
The Notice of Intent is your official application for permit coverage. You file it with the EPA (or soon NMED) before you start moving dirt. But here’s the catch: you need your SWPPP written and ready before you file the NOI.
The SWPPP comes first. Always. You can’t file an NOI without a completed SWPPP sitting on your desk. Once the NOI is approved, you get covered under the Construction General Permit (CGP). That’s your green light to start work.
If your project is under five acres, you might not need to file an NOI – but you still need a SWPPP and a posted site notice. So even small jobs have rules.
Who Is Responsible for the SWPPP?
Great question. The operator – that’s usually the owner, developer, or general contractor – holds the permit and owns the SWPPP. If you’re the one calling the shots on site, you’re responsible.
But here’s where it gets messy: multiple operators can share responsibility. A landowner might hold the permit, but the contractor runs the day-to-day BMPs. Your SWPPP needs to spell out who does what, or everyone gets blamed when something goes wrong.
What Goes Into a New Mexico SWPPP?
Your SWPPP is a living document. That means you update it as the site changes. Every SWPPP in New Mexico needs these pieces:
- Site description: Maps, soil types, drainage patterns, and nearby water bodies.
- Pollution sources: Where dirt, chemicals, or trash could leave your site.
- BMPs: Sediment control and erosion control practices you’ll use.
- Inspection schedule: How often you’ll check your BMPs (usually every seven days and after rain).
- Maintenance plan: How you’ll fix broken silt fences, clogged inlets, or eroded slopes.
- Responsible parties: Names and contact info for everyone managing stormwater.

Common Mistakes That Cost You Time and Money
Let’s talk about what goes wrong. These mistakes happen all the time:
Waiting too long to start: Your SWPPP must be ready before you file the NOI. If you wait until the last minute, you delay the whole project.
Forgetting to update: Your site changes. Your SWPPP needs to change with it. Inspectors will bust you if your plan doesn’t match what’s on the ground.
Skipping inspections: You need inspections every seven days and within 24 hours of a storm that drops half an inch or more. Miss one and you’re out of compliance.
Ignoring state vs. federal changes: New Mexico is taking over permitting soon. If you’re not paying attention, you might submit to the wrong agency or miss new rules.

What’s Changing in 2025?
Big news: New Mexico is moving toward full state control of stormwater permits. Senate Bill 21 gives NMED the power to issue permits, collect fees, and enforce violations that used to belong to the EPA.
This shift means stronger penalties for violations and closer oversight of construction sites. It also means better coordination with tribes whose water quality is affected by upstream discharges.
The good news? Your SWPPP requirements won’t change much. New Mexico will follow the same EPA framework you already know. But you’ll need to watch for updates to forms, fees, and submission portals as NMED takes the wheel.
Pro SWPPP – America’s #1 SWPPP Service stays on top of every regulatory change in New Mexico. When rules shift, we update your SWPPP automatically. You stay compliant without lifting a finger.

Best Management Practices That Actually Work
Your SWPPP is only as good as your BMPs. Here are the most common practices New Mexico projects use:
- Silt fences: Keep sediment on your site, not in the street.
- Stabilized construction entrances: Prevent trucks from tracking mud onto public roads.
- Sediment basins: Catch and settle dirt before it leaves your property.
- Erosion control blankets: Protect slopes from washing away during storms.
- Inlet protection: Stop trash and sediment from entering storm drains.
Every BMP needs regular maintenance. A broken silt fence is worse than no fence at all because inspectors will cite you for failing to maintain it.
How to Stay Compliant Without Stress
Compliance is simple if you follow three rules:
Rule one: Write your SWPPP before you start construction. No shortcuts.
Rule two: Inspect your site every week and after every big storm. Document everything.
Rule three: Update your SWPPP when the site changes. New phases, new BMPs, new inspections.
Stick to these rules and you’ll never worry about fines or shutdowns. For more guidance on Clean Water Act compliance, check out the EPA’s stormwater construction page.
SWPPP FAQs
Do I need a SWPPP for a project under one acre?
Usually no, unless your small site is part of a larger common plan that disturbs one acre or more. Even if you don’t need a full SWPPP, you still need erosion control BMPs and a posted site notice.
How long does it take to get my NOI approved in New Mexico?
The EPA typically processes NOIs within a few days, but approval can take up to two weeks. Plan ahead and submit early so you don’t delay your start date.
Who can write my SWPPP?
Anyone with experience can write a SWPPP, but it’s smart to hire a CPESC certified professional. Pro SWPPP – America’s #1 SWPPP Service has certified experts who know New Mexico rules and write compliant plans fast.
What happens if I don’t have a SWPPP?
You can face fines up to $25,000 per day, project shutdowns, and legal action from the EPA or NMED. Non-compliance is expensive and kills your schedule.
Do I need to update my SWPPP during construction?
Yes. Your SWPPP is a living document. When your site changes – new phases, new BMPs, new risks – you update the plan. Inspectors will compare your plan to what’s on the ground.
Can I use a SWPPP template?
Templates help, but every site is different. A generic template won’t cover your specific soil, drainage, or BMPs. Custom plans are always safer and more compliant.
Stop stressing about stormwater compliance. Pro SWPPP – America’s #1 SWPPP Service takes care of everything so you can focus on building. Get your SWPPP done right the first time at Pro SWPPP.
