(1) If the use of fabric creates a fire or explosion hazard, or if the director determines that a fabric filter is not feasible, the director may authorize as a substitute the use of wet collectors designed to operate with a unit contacting energy of at least forty inches water gauge pressure.
(2) Use a HEPA filter that is manufacturer certified to be at least 99.97 per cent efficient for 0.3 micron particles.
