(A) The owner or operator who uses air cleaning, as specified in this chapter shall do the following:
(1) Use fabric filter collection devices,
except as noted in paragraph (B) of this rule, as follows:
(a) Ensure that the airflow permeability, as
determined by ASTM D737, does not exceed thirty cubic feet per minute per
square foot for woven fabrics or thirty-five cubic feet per minute per square
foot for felted fabrics, except that forty cubic feet per minute per square
foot for woven and forty-five cubic feet per minute per square foot for felted
fabrics is allowed for filtering air from asbestos ore dryers.
(b) Ensure that felted fabric weighs at least
fourteen ounces per square yard and is at least one-sixteenth inch thick
throughout.
(c) Avoid the use of
synthetic fabrics that contain fill yarn other than that which is
spun.
(2) Properly
install, use, operate, and maintain all air-cleaning equipment authorized by
this rule. Bypass devices may be used only during upset or emergency conditions
and then only for so long as it takes to shut down the operation generating the
particulate asbestos material.
(3)
For fabric filter collection devices installed after January 10, 1989, provide
for easy inspection for faulty bags.
(B) There are the following exceptions to paragraph (A)(1) of this rule:
(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.
(3) The director may
authorize the use of filtering equipment other than described in paragraphs
(A)(1), (B)(1), and (B)(2) of this rule if the
owner or operator demonstrates to the director's satisfaction that
the filtering
equipment is equivalent to the described equipment in filtering
particulate asbestos material.
