1 Stormwater Pollution Prevention Training For Olmsted County Solid Waste Facilities Olmsted County Environmental Resources Department October 2011

2 Why? This stormwater training program was developed to ensure that licensed haulers, while delivering acceptable wastes to Olmsted County solid waste management facilities, do not contribute to stormwater pollution, and remain in compliance with all applicable Olmsted County solid waste management facility permit provisions and requirements. Activities that are intrinsic to the waste management industry have a high potential for contributing to stormwater pollution. Olmsted County strongly encourages the licensed haulers to take an active role in preventing stormwater pollution and safeguarding our precious water resources.

3 What Is Stormwater Runoff? Stormwater runoff is generated when precipitation from rain or snowmelt flows over land or impervious surfaces, such as parking lots, sidewalks, streets, and building roof tops, and does not percolate into the ground. As the runoff flows over impervious surfaces, it accumulates debris, chemicals, sediment, or other pollutants that may adversely affect water quality if the runoff is discharged untreated. Stormwater runoff is typically NOT treated at a treatment facility, instead it flows through a storm sewer system and discharges directly into the nearest lake, river, creek, or stream.

4 Common Stormwater Pollutants Common stormwater pollutants and sources include: Dust, soil, and sediment from eroding stream banks, construction sites, and agricultural lands. Oil, grease, and other petroleum derivatives from urban runoff and energy production. Industrial chemicals from industrial sites. Solid waste and litter from improperly secured loads. Bacteria and nutrients from pet wastes and livestock operations. Road salt from winter road application.

5 Effects Of Stormwater Pollution Common effects of stormwater pollution include: Creates areas that are unsafe for recreation, such as fishing, swimming, and boating. Causes detriment to aquatic organisms (e.g., algae blooms and fish kills). Causes damage to local economies (e.g., negatively impacts tourism, creates higher unemployment, and food costs may rise). Increases costs for drinking water treatment, resulting in higher utility costs. Increases healthcare costs as people seek medical treatment for stormwater pollution related ailments.

6 Stormwater Statistics Stormwater discharges are often the primary source of ocean, bay, lake, and river pollution in the United States. Estimates indicate stormwater contributing as much as 80% of the total water pollution in the United States. One quart of oil can contaminate 250,000 gallons of water. According to the United States Environmental Protection Agency, 40% of all United States waters are not fishable or swimmable.

7 Minnesota Industrial Stormwater Program The primary goal of the Minnesota Industrial Storm Water Program is to restore and maintain the chemical, physical, and biological integrity of the waters of the state through management and treatment of stormwater runoff from industrial sites. What do the State Industrial Stormwater Regulations mean in plain English? Discharged stormwater should only contain rain water! Stormwater must contain: No Oils or Chemicals No Construction Waste No Litter No Sediment No Toxins Only Rain in The Drain

8 Stormwater Permitting The Olmsted Waste-to-Energy Facility (OWEF) and Olmsted County Kalmar Landfill are required by federal (40 CFR ) and state (Minnesota Rules ) regulations to obtain coverage under a Minnesota Pollution Control Agency (MPCA) Industrial Stormwater Permit or certify No Exposure and be exempted from stormwater permitting requirements. The OWEF shelters all industrial materials and activities from stormwater and was granted the No Exposure Certification on September 20, The Kalmar Landfill obtained coverage under the MPCA Industrial Stormwater Permit on July 9, 2010, and is authorized to discharge stormwater associated with industrial activity.

9 OWEF No Exposure The MPCA has granted the OWEF a No Exposure exclusion from stormwater permitting for five years. The OWEF continually must ensure all industrial materials and activities are protected by a storm-resistant shelter to prevent exposure to stormwater. The OWEF voluntarily developed a comprehensive Stormwater Management Plan (SWMP) to ensure the facility does not contribute to stormwater pollution. County staff routinely performs bimonthly inspections of the OWEF. OWEF staff receives annual stormwater training.

10 Kalmar Landfill Industrial Stormwater Permit The Kalmar Landfill is permitted under the MPCA Industrial Stormwater Permit and is authorized to discharge stormwater associated with industrial activity. To minimize stormwater exposure, landfill staff continually evaluate site practices to determine how exposed materials and activities can be reduced or eliminated. The landfill developed a Stormwater Pollution Prevention Plan (SWPPP) to assist staff in understanding and properly managing stormwater runoff. County staff performs monthly inspections. Landfill staff receives annual stormwater training.

11 Best Management Practices (BMPs) To prevent or reduce stormwater pollution, Olmsted County solid waste management facility staff implements practices and operating procedures known as Best Management Practices (BMPs). BMPs implemented at County solid waste management facilities are one of two varieties: Preventative Measures design, operation, or management measures that minimize or prevent the generation of stormwater pollution. Control Measures structural devices that are installed with the purpose to capture storm water flows and provide pollutant removal.

12 Licensed Haulers And BMPs Waste collection activities have a high potential of adversely affecting the quality of stormwater runoff. Implementing and adhering to reasonable BMPs allow licensed haulers to likely remain in compliance with federal, state, and local regulations, avoid fines, citations, and/or delays, and protect Minnesota s precious natural resources. What follows in the next few slides are BMPs (requirements of the licensed haulers) that licensed haulers SHALL implement and adhere to when delivering waste to Olmsted County solid waste management facilities.

13 Spills And Leaks While on Olmsted County solid waste management facility grounds, licensed haulers shall: Ensure that vehicles and equipment are in good repair, are frequently inspected for leaks, and are maintained in accordance with the manufacturer s recommendations. Ensure all waste compactor drain holes are closed and all seams and cracks are sealed. Immediately notify a facility supervisor if they suspect a vehicle or equipment is leaking or otherwise malfunctioning in a manner that may contribute to stormwater pollution.

14 Spills And Leaks (cont.) Ensure that all waste collection vehicles contain comprehensive spill kits. The spill kits shall at a minimum contain: Broom Shovel Sorbent (preferably of combustible material) Five gallon bucket Any necessary personal protection equipment (PPE) Licensed haulers shall immediately clean up any spill and/or leak upon discovery, and are responsible for all costs associated with the cleanup event.

15 Spill And Leak Response In the event of a spill and/or leak of material, the following response must occur: 1. If it can be done safely, immediately stop the spill and/or leak at its source. 2. Call 911 if there is a fire, explosion, or threat to public safety. 3. Notify a facility supervisor of the incident. OWEF: or Kalmar Landfill: Contain the material. If it is likely the material will reach the stormwater conveyance system, immediately dike the area surrounding the material, locate the nearest down gradient stormwater conveyance system inlet, and dike or berm the inlet to prevent any material from entering. 5. Identify the spilled material.

16 Spill And Leak Response (cont.) 6. Obtain the necessary equipment to clean up the material. 7. If safe to do so, using a spill kit and implementing appropriate PPE, recover or clean up the material (using a dry cleanup method). 8. Never hose down a spill and/or leak area. 9. Dispose of all wastes related to the cleanup in accordance with all applicable federal, state, and local laws, rules, and regulations. 10.All petroleum spills greater than 5 gallons must be reported to the State Duty Officer by the person responsible for the spill. If in doubt, REPORT. MN State Duty Officer: or

17 Securing/Covering Your Loads While on Olmsted County solid waste management facility grounds, licensed haulers shall: Ensure all waste collection vehicle loads are covered and secured so as to prevent any solid waste from falling, leaking, dropping, or being blown out of the waste collection vehicle. No vehicle shall be driven or moved on any highway unless such vehicle is so constructed, loaded, or the load securely covered as to prevent any of its load from dropping, sifting, leaking, blowing, or otherwise escaping therefrom - Minnesota Statutes

18 Containers On OWEF Grounds All roll-off containers, compactors, and any other container placed on* OWEF grounds must be: Lidded (completely covered); Plugged (nothing can drain out of holes in the bottom or sides); and No materials are to be lost during loading and unloading operations. The container cover material (whether a lid or some other type of cover) must have sufficient durability and integrity and be anchored in a way to keep water from entering the container. * Placed in any position other than on the waste collection vehicle.
