ECAR
Fact Sheet for Missouri 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 Vehicle salvage businesses generate wastewater during daily operations. Sources of wastewater include hot tank solutions and parts washers. These wastewaters may contain metals that can cause them to be hazardous or they may be corrosive hazardous wastes. They may also contain oils, greases, solvents and detergents. 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. Most communities provide sewer collection and wastewater treatment facilities. If your business is connected to a sewer and treatment plant, contact them to explain the materials you wish to dispose of in the sewer system. Pretreatment. You may need to pretreat the wastewater in some way before putting it in the sewer. For example, an oil/water separator or treatment for a particular contaminant may be required. The used oil collected during pretreatment may be eligible for recycling with your used oil. Hazardous Waste. In areas where a wastewater treatment facility is not available or cannot take your water, you must carefully manage the wastewater from your shop. If the wastewater is hazardous, you must manage it by sending it to a permitted hazardous waste facility. See the ECAR Hazardous Waste Fact Sheet. If your wastewater is not hazardous, you can haul it to an approved wastewater treatment plant if the plant is willing to accept it. Also, if the wastewater is not hazardous, you may be able to treat it yourself. This will probably require a permit from the Department to assure that the treatment process you want to use will properly treat your wastewater. Disposal. If you cannot connect your shop to a wastewater treatment plant, you may be able to discharge domestic wastewater (water from restroom or kitchen facilities) to a septic system. On-site septic systems that treat domestic wastewater are regulated by county health departments. You will still need to collect any industrial wastewater (water from parts washers, floor cleaning, etc.) and manage it as described above. *Do not put your industrial wastewater down the drain unless you are connected to a sewer and treatment plant and have permission from the plant. Discharges to waters of Missouri. If your facility discharges industrial wastewater via a “point source” (such as a pipe, etc.) directly to waters of Missouri, you will be required to obtain a National Pollutant Discharge Elimination System (NPDES) permit. The Missouri Department of Natural Resources issues these permits in Missouri where they are called Missouri State Operating Permits. Waters of state include (but are not limited to) ground water, storm drains, rivers, streams, lakes and ditches. Missouri State Operating 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. When a business stores toxic materials or large amounts of potential contaminants exposed to rainfall, needs close monitoring, or is one of only a few of its kind in the state, it may need a site-specific permit. A site-specific permit takes into account the individual characteristics of the site and the storm water runoff. In some cases, the Department may require the owner or operator of a site to apply for a site-specific permit in order to better protect water quality. Links to the Regulations and Forms. Use the following links to view the regulations and permit forms pertaining to wastewater. Department Water Quality Rules 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.
