March 15, 2000 from D. P. Van Buren, PE to Barry Young titled "New BACT for Asphalt Batch Plants". e. BACT is 12 ppmvd NOx @ 15% O2 and 265 ppmvd CO @ 15% O2 regardless of fuel. However, for special situations such as temporary operations and/or remote locations where natural gas is not available, liquefied petroleum gas or fuel oil < 0.05 wt. % sulfur may be permitted to emit at higher levels as specified below: 1). "Temporary operations" using exclusively liquefied petroleum gas shall not remain at any single plant for a period in excess of 12 consecutive months, following the date of initial operation, and may be permitted up to 38 ppmvd NOx @ 15% O2and 265 ppmvd CO @ 15% O2. [Basis: Monterey Bay Unitied APCD A/C #10287] 2). "Temporary operations" using exclusively fuel oil < 0.05 wt. % sulfur shall not remain at any single plant for a period in excess of 3 consecutive months, following the date of initial operation, and may be permitted up to 55 ppmvd NOx @ 15% O2 and 265 ppmvd CO @ 15% O2.[Basis: Reference a. above] 3). For remote locations where natural gas is not available, liquefied petroleum gas may be permitted up to 38 ppmvd NOx @ 15% O2 and 265 ppmvd CO @ 15% O2 and fuel oil < 0.05 wt. % sulfur may be permitted up to 55 ppmvd NOx @ 15% O2 and 265 ppmvd CO @ 15% O2.
