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).
E=4.10 * (P) 0.67 for P <=30 tons/hr, or
E= 55 * (P) 0-"-40 for P >30 tons/hr
4. VISIBLE EMISSIONS CONTROL REQUIREMENT -As required by 15A NCAC 2D
.0521 "Control of Visible Emissions," visible emissions from the emission sources,
manufactured after July 1, 1971, shall not be more than 20 percent opacity when averaged
over a six-minute period, except that six-minute periods averaging not more than 87 percent
opacity may occur not more than once in any hour nor more than four times in any 24-hour
period. However, sources which must comply with a visible emissions standard in 15A
NCAC 2D .0524 "New Source Performance Standards" or .1110 "National Emission
Standards for Hazardous Air Pollutants" shall meet that standard instead of the 2D .0521
visible emissions standard.

iii. the time when the malfunction or breakdown is first observed,
iv. the expected duration, and
V. an estimated rate of emissions.
b. Notify the Director or his designee immediately when the corrective measures have
been accomplished.
This reporting requirement does not allow the operation of the facility in excess of
Environmental Management Commission Regulations.
6. FUGITIVE DUST CONTROL REQUIREMENT -As required by 15A NCAC 2D .0540
"Particulates from Fugitive Dust Emission Sources," the Permittee shall not cause or allow
fugitive dust emissions to cause or contribute to substantive complaints or excess visible
emissions beyond the property boundary. If substantive complaints are received or excessive

minutes in any one hour(using Reference Method 22 in 40 CFR, Appendix A), the owner or
operator may be required to submit a fugitive dust plan as described in 2D .0540(f).
"Fugitive dust emissions" means particulate matter that does not pass through a process
stack or vent and that is generated within plant property boundaries from activities such as:
unloading and loading areas,process areas stockpiles, stock pile working, plant parking lots,
and plant roads (including access roads and haul roads).

does not mean that the activity is exempted from an applicable requirement or that the owner
or operator of the source is exempted from demonstrating compliance with any applicable
requirement.
2. When applicable, emissions from stationary source activities identified above shall be
included in determining compliance with the permit requirements for toxic air pollutants
under 15A NCAC 2D .1100 "Control of Toxic Air Pollutants" or 2Q .0711 'Emission Rates
