EPA Coal Storage Pile Rules

Affected facilities constructed, reconstructed or modified after May 27, 2009 are required to prepare and operate in accordance with a submitted fugitive coal dust emissions plan. The plan must identify and describe the control measures the owner/operator will use to minimize fugitive coal dust emissions from each open storage pile.

The EPA identified fogging systems and wind barriers as two of the accepted control measures.  DSI DustTamer Wind Fence Systems and Dry Fog Systems can help you comply with these regulations avoiding the use of chemicals. With chemical systems the EPA requires that the user consider in their dust control plan the site-specific impacts associated with the use of chemical dust suppressants (e.g.,water runoff, water quality concerns).

EPA Announcement

EPA designates Fogging Systemsas Best Demonstrated Technology(BDT) for PRB, sub bituminous & lignite coal at Coal Preparation & Processing Plants!

On September 25, 2009 the United States Environmental Protection Agency (EPA) revised emissions control requirements for new coal preparation plants. These revisions were based on a variety of input and comments from those directly involved in the coal industry, including coal mines, power plants, consultants, engineering firms and suppliers of air pollution control systems.

The EPA findings have created new rules that they published in the Federal Registers on October 8, 2009. The new rules designate "Fogging Systems" as a Best Demonstrated Technology (BDT) for coal handing equipment used on sub bituminous and lignite coals.

BDT as identified by the EPA, is the most effective commercially available means of treating specific types of hazardous waste. Public testimony given to the EPA on fogging systems has revealed what we at DSI has been saying for many years, that Dry Fog can be the most cost effective dust control system available, yielding results as good or better than any other control measure.

Power Magazine July 2010 / Use Dry Fog to Control Coal Dust Hazards

Fogging systems have been successfully used in the material-handling industry for more than 30 years to control explosive dust at transfer points. Today, fogging systems are an EPA Best Demonstrated Technology for subbituminous coal preparation plants.

The importance of properly managing fugitive dust emissions to ensure employee safety and equipment protection can't be overstated. If you are a plant owner or operator who handles coal, then you are responsible for improving plant housekeeping, providing adequate employee training, and ensuring that the proper safety equipment is available and functional in the case of an emergency. I hear people say that safety is paramount at the plants I visit, yet many plants continue to ignore all the red flags when it comes to aggressively controlling fugitive dust, especially those plants that handle Powder River Basin (PRB) coal. There's no longer any excuse for failing to have the best dust-management systems and practices

A Brief History of Recent Coal Dust Standards

The hazards of combustible coal dust were the subject of an Investigation Report released by the U.S. Chemical Safety and Hazard Investigation Board (CSB) in November 2006. In this landmark report, the CSB reported on its investigation of dust explosions in general industry between 1980 and 2005. The CSB found that 281 combustible dust incidents killed 119 and injured 718 workers and "extensively damaged industrial facilities" in 44 states. The report concluded: "These findings illustrate the seriousness of the combustible dust hazard in U.S. workplaces, yet no comprehensive federal Occupational Safety and Health Administration (OSHA) standard exists to control the risk of dust explosions in general industry."
