The following fact sheet was prepared by the ECAR Center staff. Once prepared, each ECAR Center fact sheet undergoes a review process with the applicable state environmental agency(ies). You can check on the status of the review process here. Please read the disclaimer on the status page. While we have tried to present a summary of the essential information on this topic, you should be aware that other items, such as local regulations, may apply to you.

What You Need to Know

The Clean Water Act requires virtually every automotive salvage or recycling operator to obtain a stormwater permit. The exceptions to this rule are few, and they are explained further in the detailed information provided below. Therefore, if you own or operate a salvage or recycling operation and you do not currently have a stormwater permit, you most likely are out of compliance. The purpose of this fact sheet is to help you either to get into compliance or to assist you to develop a more efficient and effective compliance strategy.

Rain or snow falling on your property can pick up contaminants as it runs off, and can carry the contaminants through drainage systems directly into streams, rivers, and lakes. The term "stormwater" refers to this type of runoff.

In 1987, Congress mandated that "industrial" sites obtain stormwater permits. In 1990, EPA defined "industrial" to include, among many other types of sites, "salvage yards and automotive [recyclers]." [Title 40 CFR 122.26(b)(14)(vi)]. These mandates apply across the country, regardless of your state. Congress and EPA took this action because stormwater that comes in contact with metals, oil and grease, used batteries and tires, and other materials common at automotive recycling facilities may cause localized pollution that can affect the local community’s ability to swim and fish in lakes, rivers, and streams.

For example, the mercury that still may be found in old automotive switches or even some new parts is toxic to humans and to the fish they may catch and eat. By obtaining a stormwater permit, and more importantly, by taking some common sense actions under the permit to prevent stormwater contamination, you can provide your community with environmental benefits to compliment the value of recycling end-of-life vehicles.

Although Congress and EPA created the national rules that provide the basic framework for stormwater regulations, the rules are implemented by the individual state environmental agencies. EPA may help certain states develop programs and it provides guidance to all states, but for the most part, you obtain a stormwater permit from your state environmental agency. Information about your state permit, compliance requirements, contact information, and other helpful hints are provided in the following pages of this site. The most important part of the compliance program is developing a stormwater pollution prevention plan, and this site will help you to develop such a plan. The key for you is to make sure that you implement the plan and adhere to your legal obligations.

Regulations

How to Get Permit Coverage. Start by downloading and carefully reading the Notice of Intent (NOI) form and General Permit (TNR050000) found below under "Links to the Regulations and Forms".

To apply for coverage under the general permit, you must:

1. Prepare and implement a stormwater pollution prevention plan (SWPPP) in accordance with part IV of the general permit.

2. Complete and submit a notice of intent (NOI) form (which can be found in Addendum B of the general permit) along with the (SWPPP) that has been prepared and implemented to:

3. If your auto recycling operation discharges stormwater to a municipal stormwater sewer system, you must make a copy of the SWPPP available to your municipality upon request.

Unless the Tennessee Division of Water Pollution Control (TDWPC) notifies you to the contrary, you are covered under the general permit 5 days after the date that the NOI is postmarked.

The general permit (TNR050000) expires on December 31, 2006.

How to Comply with the Permit Requirements. To maintain coverage under the general permit, you must comply with all the terms of the permit (see parts IV through VII of Permit TNR050000). Below is a summary of key requirements.

1. Prior to submitting a NOI, develop and implement a stormwater pollution prevention plan (SWPPP). The requirements of the plan are described in the permit. The SWPPP must be retained on-site and made available to the authorities upon request. SWPPPs should be submitted to the appropriate Division’s Environmental Assistance Center (EAC) (listed by geographical region on page 15 of the general permit).

2. Update the SWPPP as necessary whenever there is a change in your operations that has a significant affect on stormwater, and submit the updated SWPPP to the appropriate EAC.

3. Visual inspections as described in Part IV.F of the general permit must be performed at a minimum frequency of once per month.

4. Quarterly inspections (described in Section M of the general permit) must be conducted. Reports summarizing the quarterly inspections must be prepared and retained on-site as part of the SWPPP.

5. Comprehensive site compliance evaluations must be conducted at least once a year in order to confirm the accuracy and effectiveness of the plan. A report summarizing the scope of the evaluation and the subsequent actions that were taken must be prepared and retained as part of the SWPPP for at least 3 years after the date of the evaluation.

6. Automotive recycling operations must collect and analyze samples of their stormwater at least one time each calendar year. The instructions for monitoring are contained in part V of the permit.

7. Automotive recycling operations that are required to monitor, as described above, must submit monitoring results for each outfall associated with industrial activity on TMSP storm water monitoring report form(s). These report forms must be postmarked no later than the March 31^st of the following calendar year and sent to:

Enforcement and Compliance Section
Tennessee Division of Water Pollution Control
6^th Floor L & C Annex
401 Church Street
Nashville, TN 37143-1534

Your SWPPP must include a description of potential sources of stormwater pollution and measures and controls, including best management practices (BMPs) that will be implemented at your facility to prevent or minimize stormwater contamination. When developing the SWPPP you must consider the use of certain BMPs that EPA and TDWPC consider applicable to specific areas such as vehicle dismantling/storage areas and fluids storage areas. For more specific information on developing a Pollution Prevention Plan, visit the ECAR SWPPP fact sheet.

Self-Audit Checklist

When an inspector comes to your facility, there are certain things he or she checks to see if you are in compliance with environmental regulations. It makes good sense for you to perform a "self-audit" and catch and correct problems before they result in penalties. Also, there are some compliance incentives associated with self-audits (see Audit Policy Page).

Use the following list to audit your stormwater permit.

1. Is your facility covered under a general permit or does your facility have an individual stormwater permit? Verify that your facility is either covered under the general permit (TNR050000) or has an individual stormwater permit issued by TDWPC.
2. Has your facility developed and implemented a stormwater pollution prevention plan? Verify that a SWPPP has been prepared and implemented and is available onsite for inspection. Review the plan and verify that BMPs have been implemented. Update the plan when operational changes occur that impact stormwater.
3. Has your facility conducted stormwater sampling and visual inspections? Review your records to verify that annual sampling and quarterly inspections have been performed. Proof of these activities must be incorporated into your SWPPP.
4. Has your facility maintained monitoring results and records? Verify that all monitoring and inspection records are maintained for at least three years from the date of sample collection or for the term of the permit, whichever is greater.

Best Management Practices (BMPs)

The following is a list of BMPs for auto salvage facilities identified by EPA when the stormwater regulations were published:

Dismantling and vehicle maintenance:

• Drain all fluids from vehicles upon arrival at the site. Segregate the fluids and properly store or dispose of them.
• Maintain an organized inventory of materials used in the maintenance shop.
• Keep waste streams separate (i.e. waste oil and solvents). Non-hazardous substances that are contaminated with hazardous substances are considered a hazardous waste.
• Recycle antifreeze, gasoline, used oil, mineral spirits and solvents.
• Dispose of greasy rags, oil filters, air filters, batteries, spent coolants and degreasers properly.
• Label and track the recycling of waste material.
• Drain oil filters before disposal or recycling.
• Store cracked batteries in a nonleaking secondary container.
• Promptly transfer used fluids to the proper container.
• Do not pour liquid waste down floor drains, sinks or outdoor storm drains.
• Plug floor drains that are connected to the storm or sanitary sewer. If necessary, install a sump that is pumped regularly.
• Inspect the maintenance area regularly for proper implementation of control measures.
• Filter stormwater discharges with devices such as oil-water separators.
• Train employees on proper waste control and disposal procedures.

Outdoor vehicle, equipment and parts storage:

• Use drip pans under all vehicles and equipment waiting for maintenance and during maintenance.
• Store batteries on impervious surfaces. Curb, dike or berm this area.
• Confine storage of parts, equipment and vehicles to designated areas.
• Cover all storage areas with permanent cover (roof) or temporary cover (canvas tarps).
• Inspect the storage yard for drip pans and other problems regularly.

Vehicle, equipment and parts washing areas:

• Avoid washing parts or equipment outside.
• Use phosphate-free biodegradable detergents.
• Consider using detergent-based or water-based cleaning systems in place of organic solvent degreasers.
• Designate an area for cleaning activities.
• Contain steam cleaning washwaters or discharge under an applicable NPDES permit.
• Ensure that washwaters drain well, and are not draining into a MS4 or surface water body.
• Do not discharge wastewater into a dry well.
• All discharges authorized by the general stormwater permit must fully meet all applicable water quality standards.
• Inspect cleaning area regularly.
• Install curbing, berms or dikes around cleaning areas.

Liquid storage in above ground containers:

• Maintain good integrity of all storage containers.
• Install safeguards (such as berms) against accidental releases in the storage area.
• Inspect storage tanks to detect potential leaks. Perform preventative maintenance.
• Inspect piping systems for failures or leaks.
• Train employees on proper filling and transfer procedures.

Improper connection with storm sewers:

• Plug all floor drains if it is unknown whether the connection is to storm sewer or sanitary sewer. Alternatively, install a sump that is pumped regularly.
• Update facility schematics to accurately reflect all plumbing connections.
• Install a safeguard against vehicle washwaters and parts cleaning water entering the storm sewer unless permitted.
• Maintain and inspect the integrity of all underground storage tanks; replace when necessary.
