3. PARTICULATE CONTROL REQUIREMENT -As required by 15A NCAC 2D .0515
"Particulates from Miscellaneous Industrial Processes," particulate matter emissions from
the emission sources shall not exceed allowable emission rates. The allowable emission rates
are, as defined in 15A NCAC 2D .0515, a function of the process weight rate and shall be
determined by the following equation(s), where P is the process throughput rate in tons per
hour (tons/hr) and E is the allowable emission rate in pounds per hour (lbs/hr).
