"Process unit" means any step in a manufacturing or process operation which results in the emission of pollutants to the atmosphere."Process weight" means total weight of all materials introduced into any process unit which may cause any emission of pollutants. Process weight includes solid fuels charged, but does not include liquid and gaseous fuels charged or combustion air for all fuels. "Process weight rate" means a rate established as follows: a. For continuous or long

- run steady

- state process operations the total process weight for the entire period of continuous operation or for a typical portion of it, divided by the number of hours of such period or portion of it. b. For cycli cal or batch process operations, the total weight for a period that covers a complete operation or an integral number of cycles, divided by the hours of actual process operation during such a period.

No owner or other person shall cause or permit any material to be produced, handled, stockpiled or transported witho ut 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 airb orne 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, discharg e points and loading points shall be equipped with collectors, sprays or other means when necessary to minimize the escape of dust.TABLE 4
