1.2.  Particulate Matter Emissions

a.  Particulate matter emissions from the Wellons boiler must not exceed 0.1 grains per standard cubic foot, corrected to 12% CO₂ or 50% excess air.

b.  Particulate matter emissions from any air contaminant source other than the boiler and fugitive emission sources must not exceed 0.1 grains per standard cubic foot.

1.3.  Fugitive Emissions

The permittee must take reasonable precautions to prevent fugitive dust emissions by:

c.  Storing collected materials from air pollution control equipment in a covered container or other method equally effective in preventing the material from becoming airborne during storage and transfer.

1.4.  Particulate Matter Fallout

The permittee must not cause or permit the emission of any particulate matter larger than 250 microns in size at sufficient duration or quantity, as to create an observable deposition upon the real property of another person. The Department will verify that the deposition exists and will notify the permittee that the deposition must be controlled.
