3
Background
  • July 19, 1999 Urban Air Toxics Strategy
    • 30 “Urban HAPs” listed
    • EPA must regulate area sources categories accounting for 90 percent of the emissions of 30 listed urban HAPs
    •  70 area source categories listed, including autobody refinishing operations and plastic parts and products surface coating (including SIC codes for metal products)
4
Background
  • NESHAP: Paint Stripping and Miscellaneous Surface Coating Operations at Area Sources published 1/9/08 (73 FR 1738)
  • Area Sources - federal HAP emissions less than 10 tons per year (TPY) of any one, and less than 25 TPY of all combined



5
Three Affected Source Categories
  • Paint stripping operations
    •  using Methylene Chloride (MeCl) to remove dried paint from wood, plastic, metal or other
  • Motor vehicle and mobile equipment spray-applied surface coating operations
  • Miscellaneous surface coating
    • spray application of coatings containing Cr, Pb, Mn, Ni, or Cd (target HAPs) to any metal or plastic parts or products that are not motor vehicles or mobile equipment
6
Sources NOT affected
  • Surface coating or paint stripping by Armed Forces, NASA, or National Nuclear Security Administration operations
  • Surface coating or paint stripping of military munitions or equipment for use by Armed Forces
  • Surface coating or paint stripping by individuals on personal vehicles, possessions, or property as a hobby or maintenance, or done by individuals for others without compensation.
    • But, rule covers surface coating by individuals of more than 2 vehicles or mobile equipment in a year, whether or not compensated
7
Sources NOT affected
  • research and laboratory activities

10
New Sources
  • A source is new if
    • Source commenced construction after September 17, 2007 by installing new equipment; and
    • the new equipment is used at a source not actively engaged in paint stripping and/or surface coating prior to September 17, 2007
      • construction of new paint booths, enclosed spray gun cleaners, paint stripping equipment to reduce MeCl emissions, or spray guns to comply with the rule does not make an existing source new

General Requirements
Paint Stripping
  • minimize emissions of MeCl using the following management practices
    • evaluate each application for need to remove paint (e.g. can part be re-coated)
    • evaluate each application for alternative to MeCl
    • reduce exposure of MeCl strippers to air
    • optimize conditions when using MeCl to reduce evaporation (e.g., if heating, use lowest possible temperature)
    • use proper storage and disposal techniques
13
General Requirements
Paint Stripping
  • if operation uses more than one ton of MeCl in a year
    • develop and implement a written MeCl minimization plan
    • post the plan in areas where activity occurs
  • if operation uses one ton of MeCl or less
    • no written plan is required, but must comply with minimization management practices
14
General Requirements
