Section 9VAC5-40-910 - Emission allocation system

A. This section applies only to fuel burning equipment installations consisting of multiple fuel burning equipment units which do not burn liquid or gaseous fuels, or both, exclusively.

B. The maximum allowable particulate emissions for a fuel burning equipment installation shall be the product of the total capacity and the emission ratio (determined in accordance with 9VAC5-40-900 A).

C. The allowable particulate emissions for a fuel burning equipment installation when operating at less than total capacity, shall be the product of the percent load, emission allocation and efficiency factor for the collection equipment. The percent load shall be the quotient of the actual load and the rated capacity. The efficiency factor for the collection equipment of each unit shall be determined using procedures set forth in 9VAC5-40-920. The emission allocation shall be determined using procedures set forth in subsection D of this section.

D. The emission allocation for each of the fuel burning equipment units of the fuel burning equipment installation shall be its designated portion of the maximum allowable particulate emissions from the fuel burning equipment installation when operating at total capacity. The portions shall be proposed by the owner initially and determined in a manner mutually acceptable to the board and the owner. Once accepted by the board, the portions may not be changed without the consent of the board.
