A Plain-English Starting Point for Junkyard, Scrap Metal, and Auto Salvage Owners on NJDEP's SM2 and RVR Stormwater Permits
If you run a scrap yard, junkyard, or auto salvage business in New Jersey, someone has probably told you that you need a stormwater permit. Maybe it was an inspector, a landlord, a lender, or the guy who owned the yard before you. It can sound strange at first, since you're not discharging anything from a pipe. But the state treats rain that runs across a yard full of metal, fluids, and dismantled vehicles as a potential source of pollution, and it regulates that runoff. The short answer is that most active scrap and vehicle recycling yards are expected to have one of two specific permits, and the right one depends on what your yard does.
This article is the entry point. We'll explain why NJDEP is paying so much attention to these yards right now, what the two permits are called and how they differ, how to tell which one fits, what the permits require, and what to do first. If you'd rather talk it through with someone, you can always reach out to RMA, and we'll tell you honestly whether you need our help.

TL;DR
Most active scrap yards and auto recyclers in New Jersey are expected to hold a NJDEP stormwater permit. Yards that process scrap metal, with or without vehicles, fall under the Scrap Metal (SM2) general permit. Yards that only recycle vehicles fall under the Vehicle Recycling (RVR) general permit. Yards that don't fit either one may need a different permit or may qualify for an exclusion. NJDEP issued a 2025 advisory saying it will inspect all permitted facilities and take enforcement action against unpermitted ones, so the first step is finding out which permit you hold or should hold.
Why Does NJDEP Focus on Stormwater at Scrap Yards and Auto Recyclers?
Think about what rain meets in a typical yard. It lands on piles of scrap, stained pavement, vehicles waiting to be drained, bins of parts coated in oil, and bare ground that has soaked up years of drips. Then it runs off, picking up whatever it touched, and heads for a storm drain, a ditch, a stream, or straight into the soil. NJDEP's own language on this is plain: runoff collects trash, chemicals, oils, and dirt, and those can end up in drinking water wells, rivers, streams, lakes, and coastal waters. Oil, coolant, rust, metal fines, and sediment are exactly the kind of material scrap and salvage operations handle all day.
That's why these industries get their own permits instead of being lumped in with everyone else. It's also why the state has been paying closer attention lately. In October 2025, NJDEP issued Compliance Advisory 2025-11, a notice aimed squarely at scrap metal and vehicle recycling operations. It says the Division of Water Enforcement will inspect all permitted scrap metal and vehicle recycling facilities, and that facilities found operating without a permit they should have will face enforcement action. The Attorney General's office has also filed suits against salvage yards over stormwater problems, including a 2024 case citing improper storage of parts, contaminated soil, and a debris pile exposed to rain.
None of that means every yard is in trouble. It means this is a good time to know exactly where your yard stands before an inspector asks.
What Is a NJPDES Stormwater Permit for a Scrap Yard?
Let's start with the vocabulary, since most yard owners have never needed it. NJPDES stands for New Jersey Pollutant Discharge Elimination System. It's the state's version of the federal Clean Water Act permit program, and NJDEP runs it. When the discharge is rain running off an industrial site, the permit is called a stormwater permit.
For most industries, New Jersey doesn't write a permit for each business. It uses general permits, which are pre-written permits for a category of business. You apply to be covered, and once NJDEP authorizes you, you follow the rules in that general permit. The state has a basic industrial general permit (called 5G2) plus several industry-specific ones, and two of those industry-specific permits are built for yards like yours.
Every one of these permits revolves around a written plan for keeping pollution away from rain. In New Jersey it's officially a Stormwater Pollution Prevention Plan, which NJDEP abbreviates SPPP. You'll also hear it called an SP3 or just a stormwater plan. We call it a SWPPP, and our guide on what a SWPPP is covers the basics. For a scrap yard, the plan maps where the messy activities happen and describes how each one is kept from touching rainwater. If you want the bigger picture on how these permits work in the state, our article on NJPDES stormwater permit requirements walks through it.
SM2 vs. RVR: Which New Jersey Scrap Yard Stormwater Permit Fits?
New Jersey has two permits written specifically for this industry. The Scrap Metal general permit is called SM2, and the Vehicle Recycling general permit is called RVR. There was an earlier Scrap Metal permit simply called SM, but NJDEP lists it as expired and no longer available. If someone tells you your yard has an "SM permit," confirm what you're covered under today. Our article on the NJ SM2 scrap metal general stormwater permit goes deeper on that one.
The dividing line is what your yard does. SM2 covers facilities that recycle scrap metal, with or without vehicle recycling. RVR covers sites that only recycle vehicles. In practice, that gives you a simple way to sort yourself.

Here's how to read your own situation. If you take in scrap metal and process or sell it, SM2 is the permit to look at, even if you also handle some cars. If your yard only buys vehicles, drains the fluids, pulls parts, and sends the shells out, RVR is the one. If you do both, NJDEP has said SM2 is built for the combined operation.
What If Your Yard Doesn't Fit SM2 or RVR?
Not every yard sorts so cleanly. A metal fabricator with a scrap bin, a towing company that stores vehicles, or a body shop with a pile of damaged parts is a different conversation than a yard processing metal outdoors. Depending on the activities, those sites may fall under the basic industrial permit (the 5G2 permit), may need an individual NJPDES permit, or may qualify for what's called no exposure, which applies when nothing industrial is ever exposed to rain. The answer depends on your industry classification, what's stored outside, and where your water goes, so we'd rather not guess from a distance.
What Do the SM2 and RVR Stormwater Permits Require Day to Day?
NJDEP's 2025 advisory lists what it calls some, but not all, of the best management practices these permits require. Your own permit is the final word, but the list gives you a good feel for what inspectors look at. Storage is the first area. Fluid storage, parts with oily or coolant residue, and oily scrap need to sit on an impervious surface, contained and under cover. Processed vehicles are stored with their hoods down so rain can't run through the engine compartment.
Fluid draining and dismantling come next. That work is supposed to happen indoors or in a covered area on an impervious surface, unless the stormwater from that area is collected for proper disposal. Oil, coolant, transmission fluid, brake and power steering fluids, and wiper fluid all need to be drained and disposed of correctly. Spills are the third area: you need spill kits on hand, annual spill response training for employees, and a habit of cleaning up right away and disposing of the used absorbent properly.
Then there's the paperwork side. You need a SWPPP that you follow in practice, and a copy stays at the facility. You inspect the yard at least quarterly and keep a detailed log. If you're under SM2, you sample your stormwater quarterly and submit the results, and if the results run high, the advisory expects you to add BMPs or treatment so discharges stay within the permit's design criteria. NJDEP also expects to be told when ownership changes or the business closes.
Sampling is where we see yards struggle most. We don't take samples for our clients, and we're upfront about why: you know your site, and storm windows are short and unpredictable, so a consultant driving in from somewhere else is rarely the right person to catch one. We train your team to sample correctly instead, and we explain the reasoning in our article on why you need to take your own stormwater samples. Training for your crew is also available through our online training library.
What Happens When NJDEP Inspects a Scrap Yard or Auto Recycler?
An inspector from the Division of Water Enforcement walks your yard, looks at how materials are stored, checks whether fluid draining happens under cover, and asks to see your plan, inspection log, and training records. If something doesn't line up, the inspector may issue a Notice of Violation that includes corrective actions. According to NJDEP, serious violations or corrective actions that stay outstanding lead to formal enforcement, which can include penalties. A yard found operating without a permit it should have faces enforcement that can include corrective actions and penalties as well.
The advisory also invites unpermitted operators to contact the regional Water Enforcement office and arrange an inspection to see whether a permit is needed. That's a legitimate path, but it's worth thinking through before you pick up the phone. If you've already received a notice of violation, or you're concerned about past conditions at the yard, an environmental attorney may be the right first call. We can help with the technical side, but we're not lawyers and we don't represent clients before NJDEP.
If you haven't been inspected yet and want to be ready, the practical move is to make your yard match your paperwork. Many of the problems NJDEP has flagged in enforcement cases, such as parts stored in the open, fluids handled outside, and exposed debris, are fixable before an inspector shows up. How long permit coverage takes if you're starting from scratch is a common question, and we cover it in our article on how long it takes to get a New Jersey stormwater permit.
What Should a Scrap Yard Owner Do First About Stormwater Permitting?
Start by finding out whether you already have coverage. Look for NJDEP authorization paperwork, a plan binder, or old annual certifications, and if you bought the yard, ask whether the permit was ever transferred to you. Changes of ownership are one of the things NJDEP expects to hear about, and a permit that's still in the previous owner's name is a common surprise.
Next, write down what your yard does. Do you process scrap metal, take apart vehicles, or both? What's stored outside, what's under cover, and where do you drain fluids? Then find out where your rain goes. Some sites drain to surface water or the ground, and others send runoff to a municipal system or a sewerage authority. In some older New Jersey cities, local sewer rules can apply instead of, or alongside, an NJDEP stormwater permit, so don't assume your neighbor's answer is yours. Your local sewerage authority or municipality can confirm how your site drains.
You also don't necessarily need us for all of this. NJDEP publishes a sample SWPPP template for the vehicle recycling permit, and a small, tidy yard with an owner who's comfortable with paperwork can handle a good portion of the work. We're more useful when the yard is a mix of activities, when SM2 sampling is on the table, when an inspection is coming, or when nobody on staff has time to learn the program. Our piece on writing your own SWPPP lays out where the line usually falls. And if you recycle materials in New Jersey, a stormwater permit is only one piece. Recycling operations can carry separate state approvals, and our New Jersey recycling approvals team can walk you through that side.
How Can RMA Help With Scrap Yard Stormwater Permits in New Jersey?
We're a family-run firm based in New Jersey, and we've worked with NJDEP's stormwater programs for decades. For scrap yards and auto recyclers, we help you work out which permit your yard falls under, put together a SWPPP that matches how your yard really operates, and train your team to inspect, sample, and respond to spills. After you're permitted, we offer annual support: reminders, help reading your results, plan updates, inspection prep, and answers when questions come up. You can be as hands-on or hands-off as you want.
We're also honest about fit. We're a small firm that uses senior staff, which means we're sometimes pricier than other consultants and can't always meet very tight timelines. We don't do engineering design or build treatment systems, and if you're shopping purely on the lowest price, we probably won't be your best match. If you'd like to talk it over with no pressure and no obligation, you can call us at 888-RMA-0230, email us, or fill out the form on our website. We'll tell you what we think, including when the answer is that you don't need us.
