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

.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 15A NCAC 2D .0524 "New Source
Performance Standards" or .1110 "National Emission Standards for Hazardous Air
Pollutants" must comply with applicable visible emissions requirements contained therein.

Permit No. 09413R03
Page 3
a. Notify the Director or his designee of any such occurrence by 9:00 a.m. Eastern time
of the Division's next business day of becoming aware of the occurrence and
describe:
i. the name and location of the facility,
ii. the nature and cause of the malfunction or breakdown,
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 or excessive fugitive
dust emissions from the facility are observed beyond the property boundaries for six 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(0.
"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).
7. FABRIC FILTER REQUIREMENTS includingcartridge artridge filters, baghouses, and other dry
filter particulate collection devices - As required by 15A NCAC 2D .0611, particulate matter

manufacturer's recommendations or from those given in this permit (when
applicable) shall be investigated with corrections made and dates of actions recorded
in a logbook. Records of all maintenance activities shall be recorded in the logbook.

9. CONCRETE TRUCK LOADOUT CONTROL REQUIREMENT - As required by 15A
NCAC 2D .0611, emissions shall be controlled as described in the permitted equipment list.
Water spray systems controlling emissions at the concrete truck loadout area are considered
to be equivalent to the fabric filter control system used during the Carolinas Ready Mixed
Concrete Association's emission factor testing, if all applicable requirements listed in this
stipulation are implemented. However, if later determinations are made that indicate that
this system is not equivalent, the facility will be informed in writing and given up to one
year to properly modify the control system.
a. Operational Restrictions -In order for each water spray system to be considered
equivalent to the fabric filter control system,the following conditions must be met:
i. Each water spray system shall meet the Division of Water Quality's
stormwater and/or wastewater run-off provisions.

square or circular ring at the truck loading point.
iii. The nozzles shall be easily accessible for inspection, cleaning, and
replacement.
iv. The total water flow rate of each system must be a minimum of 1.5 gallons
per minute(typical range is 1.5 to 5 gallons per minute)when truck loading is
occurring.
V. The water droplet size shall be a minimum of 200 microns and a maximum of
1/4 inch in diameter. Fog or humidification nozzles that produce most of
their droplets in the 10 micron range are unacceptable.
vi. Only fresh water shall be used as a water supply to the nozzles.
vii. Each water spray.system shall be interlocked to the truck loadout operation
such that loadout cannot occur without simultaneous operation of the spray
bar system, regardless of the weather conditions.
viii. It is unacceptable to load trucks when the system is plugged, frozen, or
otherwise incapacitated. Additionally, adequate freeze protection must be
included.
b. Inspection and Maintenance Requirements - To comply with the provisions of this.
permit and ensure that emissions do not exceed the regulatory limits,the Permittee

Permit No. 09413R03

manufacturer. In addition,the Permittee shall perform, at a minimum, a weekly
inspection and/or cleaning of each water spray system,including nozzles.
c. Recordkeeping Requirements - The results of all inspections and any variance from
the manufacturer's recommendations or from those given in this permit(when
applicable) shall be investigated'with corrections made and dates of actions recorded
in a logbook. Records of all maintenance and cleaning activities shall be recorded in
the logbook. The logbook(in written or electronic format)shall be kept on-site and
made available to DAQ personnel upon request.

listed TAPS from the facility, including fugitive emissions, will not exceed TPERs listed in
15A NCAC 2Q .0711.
a. A permit to emit any of the below listed TAPS shall be required for this facility if
actual emissions from all sources will become greater than the corresponding
TPERs.
b. PRIOR to exceeding any of these listed TPERs, the Permittee shall be responsible
for obtaining a permit to emit TAPs and for demonstrating compliance with the
requirements of 15A NCAC 2D .1100 "Control of Toxic Air Pollutants".
c. In accordance with the approved application,the Permittee shall maintain records of
operational information demonstrating that the TAP emissions do not exceed the
TPERs as listed below:
