“The 3 Ounce Rule”

As you may be aware, there is a new 3 ounce rule from the EPA Office of Air Quality.

Rule:  Spray-applied coating operations containing HAPS, HEAVY METALS, or PAINT STRIPPER using a hand-held device that creates an atomized mist of coating and deposits the coating on a substrate outside an operating spray booth, mix room, or prep-station cannot have a cup size greater than 3 ounces. 

This rule applies to: Auto-body refinishing operations that encompass a motor vehicle, and mobile equipment spray-applied surface coating operations. Or any spraying of heavy metals or paint stripper containing; methylene-chloride, chromium, lead, manganese, nickel, or cadmium.

To facilitate the 3 ounce cup requirement a 3 ounce gravity cup is available from AOM – ASTURO, or disposable liners & lids from 3M, GERSON, and/or SATA.

Additional information related to the “3 ounce rule” can be found at 40 CFR Part 63, Subpart HHHHHH (6H).
