ECAR
Fact Sheet for Massachusetts Regulations BACK to VIRTUAL TOUR 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 Wastewater is often generated by operations such as the rinsing of parts, and the washing down of engines or dirty tools. If water becomes mixed with oil, antifreeze, solvents, or other liquids, it is important that it be properly treated and contained prior to discharge. If your wastewater is currently just going down an unregulated drain, you've got a problem. Even if your activities have gone unnoticed for years, there is an increasing chance that you will be inspected. The federal EPA and the states are starting to look much more carefully at sources of water pollution that have so far remained unidentified, and they have (rightly or wrongly) decided that auto recyclers are a significant problem area. You will almost certainly need separate permits both for stormwater runoff (see the ECAR Stormwater fact sheet) and for any industrial wastewater that you generate. This page will give you an overview of how to handle your industrial wastewater. Industrial wastewater is regulated differently than sanitary wastewater. If you combine sanitary and industrial wastewater, then the mixed wastewater is regulated like industrial wastewater. All industrial wastewater discharges are regulated by federal and state regulations and in most cases, also by local regulations. Industrial Wastewater. If a facility generates industrial wastewater, there may be requirements it must meet in order to ensure that the wastewater is properly managed. There are two situations in which a facility might be required to obtain a permit for wastewater generated by the facility, depending upon how the wastewater is ultimately disposed. These two situations are discharges to waters of Massachusetts and discharges to a publicly owned treatment works (POTW). Discharges to waters of Massachusetts. If your facility discharges industrial wastewater via a “point source” (such as a pipe, etc.) directly to waters of Massachusetts, you will be required to obtain a National Pollutant Discharge Elimination System (NPDES) permit from DEP and from EPA Region 1. Waters of Massachusetts include (but are not limited to) ground water, storm drains, rivers, streams, lakes and ditches. NPDES permits can be either general or individual permits. A general permit is a “one size fits all” type of permit and is issued for specific types of discharges such as storm water runoff, non-contact cooling water or stone quarry discharges. An individual permit is site-specific and unique to a facility. Stormwater permits are considered NPDES general permits. Permits contain limits on the quantity, discharge rate and concentrations of pollutants in the water that are discharged from a point source into waters of the state. There are permit fees associated with the state permit, but not the EPA permit. Since Massachusetts is one of the few states that does not have authority to implement the federal NPDES permit program, EPA and DEP issue joint permits. Applications for NPDES permits must be submitted to and approved by EPA Region 1 and the Massachusetts DEP. For Massachusetts NPDES permits, facility owners or operators must also mail an identical copy of the EPA application forms to DEP. Discharges to a POTW. If your facility discharges industrial wastewater into a municipal sewer connected to a POTW, you may need to obtain a pretreatment permit. To meet the standards of your local sewer authority, you may need to install treatment equipment such as an oil/water separator to prevent oil and sludge from being discharged to the sewer. This is referred to as "pretreatment.” Sludge collected by pretreatment equipment will have to be periodically removed and disposed of, possibly as a hazardous waste (you must make a hazardous waste determination). In most instances, wastewater will require some form of pretreatment prior to discharge into the sewer system. If your facility disposes of its wastewater in a manner other than sending it to a POTW, it will need to determine whether it is a hazardous waste. If your wastewater is a hazardous waste, you will need to ensure that the tank storing this wastewater meets the requirements contained in the hazardous waste rules. In addition, you must ensure that it properly manages its wastewater upon removing it from the tank. See the ECAR Hazardous Waste Fact Sheet for more information. Links to the Regulations and Forms.

Massachusetts Clean Water Act – Located Under Water Pollution Control Water Permit Application Information Federal Safe Drinking Water Act Requirements 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 wastewater management activities.
Best Management Practices (BMPs) Most regulations tell you what you have to do to be in compliance, but they don’t explain how to do it. That’s where "best management practices" come into play. BMPs are proven methods that help you to get into compliance and stay there. The following BMPs are recommended for wastewater management.
