For the purpose of these regulations and subsequent amendments or any orders issued by the board, the words or terms shall have the me anings given them in subsection C of this section. B. As used in this article, all terms not defined here shall have the meanings given them in 9VAC5 Chapter 10 (9VAC5

- 10 et seq.), unless otherwise required by context. C. Terms defined. "Process oper ation" means any method, form, 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 causeany emission of pollutants. Process weight includes solid fuels charg ed, 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 p eriod 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 cyclical 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.

Except as provided in subsection C of this section, interpretation of the emission standard in subsection A of this section shall be in accordance with 9VAC5
- 40
- 22. C. For a process weight rate between any two consecutive rates in Table 4
- 19, or for rates over 50 tons per hour, the maximum allowable emission rate may be calculated by the following equation: E = 3.51 P where: E = emission rate in lb/hr. P = process weight rate in tons/hr. Statutory Authority §§ 10.1
