For a hypothetical plant with a baghouse and stack flow of 4,000 SCFM, the emission rate would be 4,000 SCFM * 0.022 gr/DSCF * 60 min/hr / 7,000 gr/lb = 0.75 lb/hr. If this plant operates up to 1,200 hours per year, annual emissions are 0.75 lb/hr * 1,200 hours/year / 2,000 lb/ton = 0.45 TPY from the stack in question.
