What does RMA handle for NPDES stormwater permitting?

We build and maintain practical, inspection-ready stormwater programs. That typically includes outfall identification, drainage and site mapping, SWPPP creation or updates, BMP selection, inspection and recordkeeping procedures, staff training, and assistance with filings like NOIs, renewals, or No Exposure Certifications when eligible.

How much does an NPDES stormwater permit project usually cost?

Pricing depends on site size, number of outfalls, drainage complexity, permit type, and your current SWPPP status. Many projects fall in the $2,000 to $10,000+ range. Smaller, straightforward sites are typically on the low end, while large or complex facilities with multiple outfalls or added requirements land higher.

How long does it take to get a SWPPP and stormwater permit paperwork completed?

Timelines vary based on complexity and how quickly we can gather site information, but most projects move quickly once we have the inputs. If you have a hard deadline due to an inspection, NOV, or internal requirement, we can often expedite scheduling as needed.

What if we already have a SWPPP and just need an update?

That’s common. If your SWPPP is in good shape, we can update maps, BMPs, inspection procedures, and documentation to match your current operations and permit requirements. If the existing plan is outdated or missing core elements, it’s often more efficient to rebuild it so it’s defensible during an inspection.

Do you only work in certain states or specific industries?

We support facilities across the U.S. and work with a wide range of industries and site types. Whether you have one location or multiple facilities, we can standardize documentation and workflows to keep your stormwater program consistent, scalable, and easier to manage.

NPDES Permitting by RMA | Our NPDES Process From Start to Finish

Your Path to NPDES Compliance: Our Process

Start the Conversation

Kickoff & Site Visit

Plan Development & Application Submission

Ongoing Compliance

The Short Version: We spend some time talking. You tell us where things stand, we help you figure out exactly what’s required, and then we lay out a clear, no-pressure path forward.

The path to NPDES & stormwater compliance always starts with a conversation. You don’t need to have all your documents ready or know every detail (that’s our job).

We’ll ask a few basic questions about your site activities, materials, and drainage to determine whether your facility needs an NPDES permit, or if you might qualify for a Non-Exposure Certification instead (if that's even an option).

We’ll also review any past permits, inspection reports, or violations to see where things stand. Some clients are just trying to get ahead of upcoming inspections, while others are responding to a regulator’s letter, a failed audit, or even worse, facing lawsuits tied to non-compliance.

Either way, we’ll give you straight answers about your situation, timelines, and what it’s realistically going to take to get you compliant with the applicable rules and regs.

Once we’ve gathered the basics, we’ll provide you with a clear scope of work, a ballpark estimate, and a straightforward service agreement. No hidden charges, no 20-page legal documents, just a plain-English outline of what we’ll do, how much it'll cost, and what you’ll get when we’re done.

The Short Version: We gather what we need to get started right away. If a site visit is required, one of our experienced consultants will come out to your facility, work efficiently, and get every detail needed to build a bulletproof NPDES compliance program for your operation.

Once we're retained, we get to work immediately. Depending on your facility and state requirements, we’ll either start remotely or schedule an on-site evaluation. During this phase, we identify your outfalls, evaluate potential pollutant sources, and review any structural or operational controls already in place.

Most site visits take just a few hours. You’ll have one of our senior environmental professionals on site (not a junior staffer or intern) to document everything accurately. We take photos, measure drainage areas, locate discharge points, and confirm whether materials, waste, or chemicals are exposed to precipitation. If there’s an easy fix that helps you reduce monitoring requirements or qualify for exemptions, we’ll tell you that too.

We work safely, efficiently, and in full coordination with your safety procedures. Whether you need us to attend a morning toolbox talk, wear PPE, or follow specific site protocols and orientations, we’ll adapt to your operation and get the job done with minimal disruption.

The Short Version: We develop your documentation, which most people call a Stormwater Pollution Prevention Plan (SWPPP) or something similar, prepare your permit paperwork, and make sure your submission gets done right.

After gathering site specific information, we draft your documentation from the ground up. Most people call it a Stormwater Pollution Prevention Plan, or SWPPP, but the name and format can vary by state. This is not a copy paste template. Each plan is written specifically for your facility, activities, drainage patterns, and state requirements, and includes a detailed facility description, drainage and flow maps, outfall locations, potential pollutant sources, Best Management Practices, and inspection forms that align with your specific permit.

We also manage the front end compliance process, including Notice of Intent or No Exposure Certification filings and any required follow up if an application is not accepted. If your state requires digital uploads, those are prepared and submitted as well. You receive a complete digital SWPPP package, with an optional hardcopy binder, organized into clearly labeled sections that explain requirements in plain language your staff can follow.

Once approved, the focus shifts to real world use and inspections. Every SWPPP we deliver is readable, defensible, and built around your permit conditions. After your plan and permit are finalized, we review the entire package with you in plain language and train your staff on implementation. A SWPPP only works if the people responsible for it understand what’s required and how to carry it out.

The Short Version: Some clients just need a permit and plan while others rely on us for the long haul. Either way, we’re here with training, audits, reporting support, and updates when you need it.

After your NPDES permit is in place, we help keep it that way. We offer ongoing support for quarterly inspections, annual training, Discharge Monitoring Reports (DMRs), and sampling coordination. If your state requires annual certification or plan updates, we’ll handle those too.

For clients that want hands-off compliance, we can manage the entire program (including reporting, recordkeeping, and even inspector correspondence). For others, we simply act as backup support when needed.

Our team keeps tabs on regulatory changes and upcoming permit renewals, so you’re never caught off guard. We can also audit your existing NPDES program to identify any gaps before an inspection happens. And if you ever receive a Notice of Violation or audit request, we’ll help you respond quickly, effectively, and professionally.

Whether you want to manage your NPDES program yourself or fully outsource it, RMA is your long-term partner in staying compliant, confident, and inspection-ready year after year.

Here’s What Comes With Your NPDES Project

Everything you need to meet NPDES & stormwater permit requirements and stay inspection-ready year-round.

An On-Site NPDES Assessment

Every NPDES permit and plan starts with an accurate understanding of your site. Our team will evaluate your drainage patterns, exposed materials, outfalls, and control measures, either through a site visit or, in some cases, via high-resolution mapping and remote assessment tools. You’ll get clear, actionable recommendations for improvements or cost-saving compliance strategies.

Permit Filing, Done Right

We handle your Notice of Intent (NOI) or No Exposure Certification (NEC) or other applicable submissions, start to finish. Whether it’s through your state’s online portal or EPA’s centralized system, we’ll ensure your registration is accepted, your permit coverage is confirmed, and your paperwork is in good standing. You’ll always know exactly where you stand, which means no guessing and no waiting for months on state replies!

A Stormwater Plan You Can Actually Use

Your Stormwater Pollution Prevention Plan (SWPPP) or whatever your state refers to it as is written specifically for your facility, not pulled from a template. We’ll include drainage and flow maps, outfall details, potential pollutant sources, and Best Management Practices (BMPs) tailored to how your site really operates. The plan is written in plain English so your team can follow it without needing a lawyer or an engineer to interpret it.

Sampling, Monitoring & Reporting Support

Stormwater permits often require quarterly sampling or benchmark reporting, and it’s easy to miss those deadlines. We’ll help you track what samples are required, interpret your lab results, and file your Discharge Monitoring Reports (DMRs) accurately and on time. If results ever exceed benchmarks, we’ll help you draft Corrective Action Reports that regulators actually accept.

Annual Stormwater Training

Annual training is required under nearly every NPDES permit in the United States, but most companies treat it like an afterthought. We don’t. RMA provides clear, flexible training options for your team (on-demand, live webinar, or on-site) so your staff knows what’s expected, what to look for, and how to properly maintain compliance throughout the year. Training is designed to be simple, useful, and built around your operations.

Ongoing Support When You Need It

Need help updating your plan next year? Want a second set of eyes on an inspection report? You’ll always have direct access to our team. Whether you need quick advice, plan revisions, or full program management, we’re here to help, and you’ll never get stuck in an endless support ticket system. We build real relationships and long-term partnerships that make compliance less stressful and more predictable.

Are We the Right Fit for Your NPDES Needs?

Our NPDES and stormwater services are built for companies that want to stop worrying about stormwater regulations and just get it done right. We're a great fit for you if:

✓ You’re unsure if you even need an NPDES permit and want clear, honest answers before spending money.

We’ve supported hundreds of facilities across the country, from single-site small businesses to national industrial operations, and helped them stay in compliance with stormwater permits under EPA, state, and municipal programs.

If your site has outdoor operations, materials, or storage, there’s a good chance you fall under NPDES stormwater regulations... and we’ve helped someone just like you get it right.

Common NPDES Service FAQs

Do I need an NPDES / industrial stormwater permit?

Most businesses that store materials outdoors or run equipment where stormwater can pick up pollutants need an NPDES permit. If rain can touch your operations and carry anything offsite, regulators usually expect you to be covered. If you're unsure, we can look at your site and tell you quickly whether you're required or not.

How much does an NPDES / stormwater permit cost?

Most NPDES permits cost anywhere from a few hundred to the low thousands of dollars depending on the permit you need and how your state’s program. If you want a consultant like us to prepare your permit application and build or update your SWPPP, expect the full package to range from around $4,000 to $15,000 on average depending on your site's complexity and details.

We always give you a ballpark number up front and a flat rate before any work begins. You may also need to budget for things like annual training, inspections, or small site improvements to meet permit requirements. As a rule of thumb, most facilities spend about 10-20% of their initial cost each year to stay compliant.

What's the difference between an NPDES permit and a stormwater permit?

A stormwater permit is actually a type of NPDES permit. NPDES is the federal program that covers all water-related discharges, and stormwater is just one category within it. If the only thing leaving your site is stormwater runoff, then you likely just need a stormwater permit under the NPDES program.

If you discharge anything beyond stormwater, like wash water or process water, you may need an individual NPDES permit with more detailed requirements. They’re both NPDES permits, the difference is simply what your facility discharges.

What's the difference between an individual and a general NPDES permit?

A general NPDES permit is a pre-written, statewide permit that thousands of facilities fall under, and if your operation fits the criteria, you can usually get coverage quickly and with far less paperwork.

An individual permit is customized specifically for your facility and is used when your operations are complex, high-risk, or don’t cleanly fit into your state’s general permit. Individual permits take much longer to review and require more technical detail, but they also give regulators and facility owners more room to address unique situations. Most facilities qualify for a general permit, but we can tell you fast which bucket you fall into.

Can I write my own SWPPP instead of hiring someone?

You can, and for very simple sites it can make sense. But most people run into trouble with mapping, flow direction, sampling requirements, and keeping the plan inspection-ready. If you want it quick and done correctly, we can build it for you.

How long does it take to get a stormwater permit or SWPPP done?

The timeline for getting an NPDES stormwater permit can vary a lot depending on your state and the type of permit you need. The application itself usually takes a few weeks to a month or two to prepare, but state review times are all over the place.

Some states turn around a general permit in about a week, while an individual permit in another state might take more than a year to be approved. It really depends on where you are and how complex your operation is. Your Stormwater Pollution Prevention Plan usually takes about a month from start to finish.

Do you have to visit our facility?

Most of the time, yes, we’ll need to visit your facility. In some cases, if you have strong maps, clear site photos, and good overhead imagery, we can handle the review virtually and prepare your application without stepping on site.

But stormwater work often comes down to details like outfalls, flow paths, slopes, and small site features that only make sense when you see them in person. Because of that, an on-site visit is usually the best way to make sure everything is accurate and defensible.

Can you help with stormwater training too?

Yes. Most permits require annual training, and we offer online, live, or on-site options. Training covers inspections, sampling requirements, good housekeeping, and what your team needs to know to stay compliant.

What if I just need an update or review of my existing SWPPP?

No problem. If your plan is decent and just needs updates to match your current permit or site changes, we can keep it quick and affordable. If your plan is outdated or missing major pieces, we'll tell you honestly and help you decide whether updating or rebuilding makes more sense.

Can one SWPPP cover multiple locations?

Each site needs its own plan because stormwater flow, materials, and risks are different at each facility. That said, we do create multi-site programs where documents share structure and inspections are standardized. This can save time and money across your whole operation.

Can our team handle the inspections and sampling ourselves?

Yes, and many of our clients do. Your permit will lay out what you need to inspect, when to inspect it, and what pollutants you'll need to sample for. We can train your team so they feel comfortable doing it on their own.

How often does my SWPPP need to be updated?

Most permits require annual reviews, plus updates whenever something meaningful changes like new materials stored outdoors, new processes, layout shifts, or new outfalls. As a rule of thumb, expect your SWPPP to need a pretty substantial rework at least every five years, even if things feel stable.

If you want, we can keep you on a yearly cycle so you’re always inspection-ready.

What about No-Exposure Certifications (NECs)?

In some cases, you might qualify for a No-Exposure Certification instead of a full NPDES stormwater permit, but the bar for this is extremely high. In our experience, about 90% of facilities don’t make the cut once we look at outdoor activities and real-world site conditions.

If you have almost anything stored outside, any outdoor operations, stockpiles, equipment, or even certain parking lot issues, you may still need a full permit. We’re happy to take a quick look and tell you which category you actually fall into so you don’t waste time guessing.

Do you only work in certain states with NPDES?

We help clients all over the country. NPDES rules change slightly state by state, but we track those differences for you. Whether you're in a strict state or a more flexible one, we'll build your program around your permit.

What do you need from us to get started?

Usually just a site map (if you have one), a quick rundown of your operations, and a short call. Photos or videos help too. If we need anything else, we'll tell you upfront. The goal is to keep your time commitment as low as possible while we handle the heavy lifting.
