The emissions from the finishing application station are directed to add-on control equipment;d. The conventional air spray gun is used to apply finishing materials and the cumulative total usage of that finishing material is less than 5.0% of the total gallons of finishing material used during the applicable semi-annual reporting period;e.

Touch-up and repair activities are conducted in accordance with the provisions of Env-A 1213.06.(b) Any source intending to use conventional air spray pursuant to (a)(5)e., above, shall demonstrate technical or economic infeasibility by submitting to the department a videotape, a technical report, or other documentation that supports the affected source's claim of technical or economic feasibility, to be determined in accordance with (c), below.(c) The following criteria shall be used, either independently or in combination, to support the affected source's claim of technical or economic infeasibility pursuant to (b), above: (1) The production speed is too high or the part shape is too complex for a single operator to coat the part and the application station is not large enough to accommodate an additional operator; or(2) The excessively large vertical spray area of the part makes it difficult to avoid runs in the stain or sagging of the part.N.H.
