Staff will meet with you to identify any areas needing further work. The easiest way to expedite issuance of your Part 70 permit is to ensure that the application is administratively and technically complete. The following tables show estimated emissions from a typical foundry operation. Steelmaking Process Emissions Process Pollutant Emission Factor Process Rate Capture Eff. TPY Coating Processes Emissions Process Pollutant Emission Factor Process Rate Control Eff.
Some items become apparent as soon as the calculations are made.
Thus a Part 70 permit would be required specifically because of PM emissions. Thus, a synthetic minor permit could be obtained that limits the PTE to less than Title V thresholds for particulate matter by including a limit in the permit for particulate matter. That permit condition must limit what solvents may be present in the paint, the maximum solvent content, and the maximum annual volume to be used. The hypothetical example shows 52.56 TPY VOC from painting. Permitting based on exceeding 10 TPY of any one HAP and exceeding 25 TPY total of all HAPs.
