"Particulates from Miscellaneous Industrial Processes," particulate matter emissions from
Hot Oil-heated Textile Finishing Oven(ID No. ES-2) 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<3 0 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

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).
7. CONTROL AND PROHIBITION OF ODOROUS EMISSIONS - As required by 15A
NCAC 2D .1806 "Control and Prohibition of Odorous Emissions" the Permittee shall not
