9 Va. Admin. Code § 5-40-22 - Interpretation of emission standards based on process weight rate tables
"Manufacturing operation" means any process operation or combination of physically connected dissimilar process operations which is operated to effect physical or chemical changes, or both, in an article.
"Materials handling equipment" means any equipment used as a part of a process operation or combination of process operations which does not effect a physical or chemical change in the material or in an article, such as, but not limited to, conveyors, elevators, feeders or weighers.
"Physically connected" means any combination of process operations connected by materials handling equipment and designed for simultaneous complementary operation.
"Process operations" means any method, from, action, operation or treatment of manufacturing or processing, including any storage or handling of materials or products before, during or after manufacturing or processing.
"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:
"Production rate" means the weight of final product obtained per hour of operation. If the rate of product going to storage can vary, the production rate shall be determined by calculation from the feed rates of raw material.
|E = [EG - EL]||P - PL||+ EL|
|PG - PL|
where: E = emission rate being calculated.
EL = emission rate for PL as determined from the process weight rate table.
EG = emission rate for PG as determined from the process weight rate table.
P = process weight rate of the unit.
PL = process weight rate in the process weight rate table which is closest to but less than the process weight rate of the unit.
PG = process weight rate listed in the process weight rate table which is closest to but greater than the process weight rate of the unit.

State regulations are updated quarterly; we currently have two versions available. Below is a comparison between our most recent version and the prior quarterly release. More comparison features will be added as we have more versions to compare.
