|
- 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
|
|
11
|
- New sources must comply by January 9, 2008 or start-up of operations
- Existing sources must comply by January 9, 2011
|
|
12
|
- 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
|
- 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
|
- 1: painters must be
certified as completing training in proper spray application of surface
coatings, setup and maintenance of spray equipment
- except students of accredited surface coating training program who are
under the direct supervision of an instructor who is certified
|
|
15
|
- 2: spray-applied coatings
must be applied in spray booth, preparation station, or mobile enclosure
that meets a and b, or c, and d:
- a: fitted with filter
system demonstrated to have 98% collection efficiency, using vendor
provided filter efficiency data, or using waterwash spray booths
operated to manufacturer’s specs
- b: booths and prep stations
for complete motor vehicles or mobile equipment must
- have full roof and four walls or side curtains, and operate and
negative pressure; OR
- use downdraft booth operated at up to, but no more than, 0.05 inches
w.g. positive pressure
|
|
16
|
- 2: spray booths, prep stations, or mobile enclosures
