Texas Natural Resource Conservation Commission Austin Texas Interoffice From: Jerry Demo To: Jim Myers, P.E. Date: August 28, 1979 Subject: Applicability of NSPS Subpart Y - Standards of Performance for Coal Preparation Plants Subpart Y is applicable to any of the following affected facilities in coal preparation plants which process more than 200 tons per day: Thermal dryers, pneumatic coal cleaning equipment (air tables), coal processing and conveying equipment, coal storage systems and coal transfer and loading systems. Definitions. "Coal preparation plant" means any facility (excluding underground mining operations) which prepares coal by one or more of the following processes: breaking, crushing, screening, wet or dry cleaning and thermal drying. "Coal" means all solid fossil fuels classified as anthracite, bituminous, subbituminous or lignite. "Coal storage system" means any facility used to store coal except for open storage piles. "Coal processing and conveying equipment" means any machinery used to reduce the size of coal or to separate coal from refuse and the equipment used to convey coal to or remove coal and refuse from the machinery. This includes, but is not limited to breakers, crushers, screens and conveyor belts. Since facilities such as power plants, cement kilns and lime kilns have some sort of breakers, crushers or screens in their coal handling, Subpart Y of 40 CFR 60 does apply if these coal preparation plants can process more than 200 tons per day. cc: James Draper, Source Evaluation Regional Supervisors
