9VAC5-40-1840. Standard for particulate matter

A. No owner or other person shall cause or permit any material to be produced, handled, stockpiled or transported without taking measures to reduce to a minimum any particulate matter from becoming airborne. Where it is practical to measure the emission, the emission shall not exceed the limits established by Table 4-14. All such airborne particulate matter emanating from the yards, sidings or roads of such operations shall be considered fugitive dust and shall be controlled as stipulated in 9VAC5-40-1860 . All crushers shall be fitted with liquid sprays or other appropriate systems which effectively limit the escape of airborne dust. Vibrating and shaker screens handling dry materials shall be enclosed or fitted with a collector system which will prevent the release of more than 0.05 grains per standard cubic foot. All feeders, elevators, conveyors, transfer points, discharge points and loading points shall be equipped with collectors, sprays or other means when necessary to minimize the escape of dust.
