Mobile Spray Coaters

The Puget Sound Clean Air Agency has historically regulated spray coating operations with a focus on preventing nuisances to the public.  This effort has relied on the use of low emission coatings, effective work practices to minimize emissions, and emission controls that capture and control the spray coating releases.  One of the keys to that interest is to have spray coating be performed in an exhausted enclosure with paint overspray emission controls and a vertical, unobstructed discharge for the exhaust.  Spray coating outside of an exhausted enclosure requires a case specific approval has been approved on a limited basis.

Awareness of a specific industry category of mobile spray coaters working on small repairs that require touch-up painting for vehicles was growing, and approvals issued by this Agency for some businesses in this category.  That awareness and growth in this business sector led to the adoption of new regulations which provide specific requirements that apply to all businesses in this category.  The important features of the updated regulations address the business mobility requirements and size of repair which is allowable outside of an exhausted spray booth.  The information available on this website covers the regulatory details for the mobile spray coating businesses and also provides information for the consumers of their services.
