Current through Register Vol. 41, No. 4, October 8, 2024
Section 9VAC5-40-930 - Standard for sulfur dioxideA. No owner or other person shall cause or permit to be discharged into the atmosphere from any fuel burning equipment installation any sulfur dioxide emissions in excess of the following limits: 1. S = 2.64K (AQCR 1 through 6).2. S = 1.06K (for liquid or gaseous fuels - AQCR 7).3. S = 1.52K (for solid fuels - AQCR 7). where:
S = allowable emission of sulfur dioxide expressed in pounds per hour.
K = heat input at total capacity expressed in Btu X 106 per hour.
B. Where there is one or more units in a fuel burning equipment installation and where the installation can be shown, to the satisfaction of the board, to be in compliance when the installation is operating at total capacity, the installation will be deemed to still be in compliance when the installation is operated at reduced load or one or more units are shut down for maintenance or repair, provided that the same type of fuel with the same sulfur content, or an equivalent, is continued in use.C. For installations in AQCR 7 at which different fossil fuels are burned simultaneously, whether in the same or different units, the allowable emissions shall be determined by proration using the following formula: View Image
where
PS = prorated allowable emissions of sulfur dioxide expressed in pounds per hour.
X = percentage of heat input at total capacity derived from liquid or gaseous fuel.
Y = percentage of heat input at total capacity derived from solid fuels.
K = heat input at total capacity expressed in Btu x 106 per hour.
