On October 8, 2009, EPA promulgated amendments to the New Source Performance Standard (NSPS) for Coal Preparation and Processing Plants, 40 CFR Part 60 Subpart Y. Subpart Y regulates affected facilities located at coal preparation and processing plants which process more than 200 tons of coal per day. This final rule is effective on October 8, 2009, and the final amendments include:
- Revision to the definition of thermal dryers for units constructed, reconstructed, or modified after May 27, 2009, to include both direct and indirect dryers drying all coal ranks (i.e., bituminous, subbituminous, lignite, and anthracite coals) and coal refuse.
- Revision to the definition of pneumatic coal cleaning equipment for units constructed after May 27, 2009, to include pneumatic coal-cleaning equipment cleaning all coal ranks.
- Revision to the definition of coal to include coal refuse.
- Revisions to the emission limits for particulate matter and opacity standards for thermal dryers, pneumatic coal cleaning equipment, and coal handling equipment constructed, modified, or reconstructed after April 28, 2008.
- Establishment of a sulfur dioxide (SO2) emission limit and a combined nitrogen oxide (NOX) and carbon monoxide (CO) emissions limit for thermal dryers constructed, modified, or reconstructed after May 27, 2009, located at coal preparation and processing plants.
- Establishment of work practice standards to control fugitive coal dust emissions from open storage piles constructed, modified, or reconstructed after May 27, 2009, located at coal preparation and processing plants.
- Minor revisions to the emissions testing, monitoring, recordkeeping and reporting requirements.
Preparation and submittal of a fugitive coal dust emissions control plan is required for affected open storage piles, which, by definition, include the equipment used in the loading, unloading, and conveying operations of the affected facility. In the fugitive coal dust emissions control plan, an owner or operator is required to specify the control measures that will be utilized and explain how the selected measures are appropriate for the site conditions. Examples of control measures include locating the sources inside a partial enclosure, installing and operating a water spray or fogging system, and applying chemical dust suppressants, among others. The fugitive coal dust emissions control plan must be submitted to the Administrator or delegated authority prior to the startup date for the affected facility or 30 days after the effective date of this rule (i.e., by November 7, 2009), whichever is later.
The details of the amendments and the final rule can be obtained from Federal Register Volume 74, No. 194, located at: http://www.epa.gov/EPA-AIR/2009/October/Day-08/a23783.htm. If you have any immediate questions on this topic don't hesitate to call your local Trinity office.
