A hazardous material is any biological, chemical, or physical material with properties that make it dangerous or potentially harmful to human health or the environment. Hazardous materials can be released to the environment in a variety of ways. | A hazardous material is any biological, chemical, or physical material with properties that make it dangerous or potentially harmful to human health or the environment.

Minimizing or eliminating contact of hazardous materials with stormwater can significantly reduce pollution of downstream waters. Proper hazardous material handling and storage also contributes to employee health, an organized work place, and efficient operation. | Minimizing or eliminating contact of hazardous materials with stormwater can significantly reduce pollution of downstream waters.

+ | [https://stormwater.pca.state.mn.us/index.php?title=Potential_stormwater_hotspots Hotspot facilities] are facilities that produce higher levels of stormwater pollutants and/or present a higher potential risk for spills, leaks or illicit discharges. Hazardous material storage and handling is of particular concern in these areas. Common [[Glossary#M|Municipal Separate Storm Sewer System]] (MS4) owned or managed hotspot facilities are those that handle solid waste, wastewater, road and vehicle maintenance, and yard waste, such as | ||

− | + | Spill prevention plans are created for prevention as opposed to after-the-fact reactive measures. Specifically, SPCC Plans are required by the EPA for oil spill prevention at facilities that meet the following three criteria: | |
− | + | *non-transportation-related | |
− | + | *having an aggregate aboveground storage capacity greater than 1,320 gallons or a complete buried storage capacity greater than 42,000 gallons, and | |
− | + | *have a reasonable expectation of a discharge into or upon navigable waters of the United States. | |
− | + | Remember that a spill of only one gallon of oil can contaminate a million gallons of water. Even if an SPCC is not required at your facility, spill prevention plans for any and all hazardous materials can be an effective preventive measure and training tool (see Employee Training below), and SPCC Plans provide a good framework for any type of spill prevention plan. For details on what to include in spill prevention plans see the EPA (see [https://www.epa.gov/oil-spills-prevention-and-preparedness-regulations] and [https://www.epa.gov/sites/production/files/documents/spccbluebroch.pdf]) and [https://www.pca.state.mn.us/sites/default/files/c-er1-02.pdf MPCA] guidance documents. | |

Municipalities and other regulated MS4s can greatly reduce potential water quality impacts by creating chemical application programs and training all full time and seasonal employees that are responsible for handling hazardous wastes. Consider registering city staff into existing training programs or providing in-house training. In-house training could include the development of guidance documents for trainees to keep with them on the job site. | Municipalities and other regulated MS4s can greatly reduce potential water quality impacts by creating chemical application programs and training all full time and seasonal employees that are responsible for handling hazardous wastes.

However, providing cover over hazardous materials stored outdoors can be equivalent to the cost of a pole building ($5 to $12 per square foot) and a concrete slab ($3 to $6 per square foot). If waste reduction measures are taken, an accurate inventory is maintained, and regular waste disposal is implemented, MS4s can minimize the amount of materials stored onsite, decreasing costs. | ||
