corrective actions to eliminate the cause of the alarm

. ( F ) The operator shall maintain filters and operate the baghouse such
that the BLDS alarm activation is minimized and the cumulative
number of hours of alarm activation within any continuous six

month rolling period do not exceed more than five percent of the total operating hours in that period after following the procedur es of subparagraph (e)(3)(G), in cluding

, but not limted to

, shut down
of the equipment as specified

. ( G ) Each time the alarm activates, t he operator shall count the alarm
time as the actual length of time of the elevated emissions that
caused the alarm and record it

. If the inspection of the baghouse, pursuant to subparagraph (e)( 3 )( E ), demonstrates that no visible emissions are occuring in conjunction with the alarm and that no corrective actions are necessary to the baghouse equipment , no alarm time will be counted. If cumulative alarm time exceed s five
percent of the total operating hours based on any continuous six

month rolling period

, the operator shall shut down the equipment that vents into the baghouse until necessary actions are taken to
elim inate the elevated emissions. (4) Notwithstanding the provisions of paragraph (e)(1) and subparagraph (e)(3) (A) applicable to Tier 3 units , the operator of hot mix asphalt production equipment may conduct daily visible emissions monitoring , as described in paragraph (e)(1), in lieu of BLDS installation
