Proposed Pa. Regulations on Industrial Cleaning Solvents

Date: January 01, 2014

Control of VOC Emissions from Industrial Cleaning Solvents:  This proposed rulemaking would regulate VOC emissions from the use of industrial cleaning solvents to remove adhesives, inks, paint, soil, oil, or grease from a production-related or maintenance-related work area or from a part, product, tool, machinery, equipment, vessel, floor, or wall.

The owner and operator of an affected facility at which the total actual VOC emissions from all cleaning operations at the facility are equal to or greater than 15 pounds per day, before consideration of controls, would be required to either use compliant cleaning materials or operate an add-on air pollution control device to reduce VOC emissions.  These owners and operators would also be required to implement specified work practice requirements for cleaning solvents, used shop towels and waste materials. 

Compliant cleaning solvents must meet either of these limits:  a vapor pressure less than 8 millimeters of mercury or a VOC content less than or equal to 50 grams of VOC per liter of cleaning solvent (0.42 pounds of VOC per gallon of cleaning solvent). 

The owners and operators of all affected facilities, including those owners and operators of affected facilities that have total actual VOC emissions below 15 pounds per day, before consideration of VOC emission controls, would be subject to certain recordkeeping and reporting requirements. 

The 15 pounds or more per day of VOC emissions is approximately equivalent to the evaporative loss from about 2 gallons of solvents per day.  

Examples of compliant lower vapor pressure solvents include but are not limited to mineral spirits and Stoddard solvents.  Solvents exempted by the EPA such as acetone, would also be subject to the proposed rulemaking requirements.

Examples of potentially affected industries include computer and electronic product manufacturing, computer storage device manufacturing, repair and maintenance of electronic and precision equipment, appliance repair and maintenance, reupholstery and furniture repair, ball and roller bearing manufacturing, construction machinery manufacturing, commercial and industrial machinery and equipment repair and maintenance, sign manufacturing, food product manufacturing, fabricated metal product manufacturing, and fiber and fabric manufacturing.
