15A NCAC 02D .0511      PARTICULATES FROM LIGHTWEIGHT AGGREGATE PROCESSES

(a)  The owner or operator of a lightweight aggregate process shall not cause, allow, or permit any material to be produced, handled, transported or stockpiled without taking measures, such as wet suppression, to reduce to a minimum any particulate matter from becoming airborne to prevent the ambient air quality standards for particulate matter, both PM10 and total suspended particulates, from being exceeded beyond the property line.

(b)  Fugitive non-process dust emissions from lightweight aggregate processes subject to this Rule shall meet the requirement of 15A NCAC 02D .0540.

(c)  The owner or operator of any lightweight aggregate process shall control process-generated emissions:

(1)           from crushers with wet suppression; and

(2)           from conveyors, screens, and transfer points,

such that the applicable opacity standards in 15A NCAC 02D .0521 or .0524 are not exceeded.

(d)  Particulate matter from any stack serving any lightweight aggregate kiln or lightweight aggregate dryer shall be reduced by at least 95 percent by weight before being discharged to the atmosphere.
