1) Location
B.V. Hedrick Gravel and Sand is located at 403 B.V. Hedrick Gravel Plant Road, off Hwy 74 East near
Lilesville,NC, in Anson County.
Directions
From FRO,take Hwy 401 South to Wagram. Turn right at Old Wire Road(Hwy144)and go— 11 '/2 miles
to Laurel Hill. Turn right at Hwy 74, and go west—30 miles toward Lilesville; you'll pass Rockingham and
then the Pee Dee River entering Anson County. Look for Gravel Plant Road on the left about 5 I/2 miles
after crossing the river.There will be a B.V. Hedrick Gravel and Sand Company sign at entrance of road.
Turn left, follow gravel drive, and after crossing the railroad tracks,the scale house will be to the right at
entrance to plant. Check in at scale house and ask for the superintendent, Tim Jones.
Safety considerations: Standard DAQ safety equipment,plus safety vest.Be aware of any blasting that might
occur,as well as all of the large mobile equipment(haul trucks,water trucks,and loaders)on the property.
Avoid walking underneath conveyors that are carrying production materials.
2) Facility and Process Descriptions
B.V. Hedrick Gravel and Sand Company is a mining facility that primarily produces sand for commercial
use and is permitted for crushing gravel.Two of the commercial uses include aquarium and golf course sand.
This particular operation employs—3 employees and production hours vary, depending on demand for the
product. The facility is synthetic minor for NO,,emissions from their diesel electrical generator equipment.
BV Hedrick Gavel and Sand has requested a limitation of no more than 100 tons/yr of NOx emissions to
avoid Title V requirements.They also have requested limiting operation to 12 hours operation per day, 365
days per year(4,3 80 hours)to avoid Title V requirements.
This facility is a quarry which extracts mainly granite from the earth. The granite and crushed stone products
are loosened by drilling and blasting, and then are loaded by power shovel or front-end loader into large haul
trucks that transport the material to the processing operations. Primary operations include a jaw, which is used
for initial crusher reduction, and a series of conveyors.This crusher product is next fed through a grizzly
feeder for undersize material, and then is discharged onto a conveyor, where it goes through more screening

processes,until it is conveyed to a surge pile for temporary storage or sold as coarse aggregate.The facility
uses wet suppression throughout all the processes. The finest product is sold to customers, who then bag and
sell the "sand",which is used mainly in small aquariums.
3) Permitted Emission Sources
At the time of the source test, BV Hedrick Gravel and Sand Company was operating under Air Permit
No. 09572R03,which became effective on 12 October 2010, expires 30 September 2015, and includes
the following emission sources and control devices:

This Method 9 source test will be used to show compliance with 15A NCAC 2D .0524 NSPS, Subpart 000
(specifically,VE< 10%opacity from conveyor belts, screening operations, and other affected facilities and
<15%VE from crushers).
The sources being tested are the drop-off points from 2 conveyors,which are transfer points for the facility's
C50 portable crushing plant,which started up operation on site on 14 June 2011. The latest submitted
equipment diagram is in the facility's file folder. The ID#s for these pieces of equipment are as follows:
J1: 50"x 26"jaw
C3: 42" discharge conveyor
C4: 26" side conveyor
2 other equipment pieces associated with this portable plant but not subject to NSPS are:
F2: 46 '/2"x 169"grizzly feeder
G4: 350 Cat C9 engine
4) Source Test Observations Summary
On 28 September 2011,I (Cindy Grimes, of FRO DAQ)observed a Method 9 source test at BV Hedrick
Gravel and Sand Company,near Lilesville,NC in Anson County. As previously mentioned,the purpose of this
test was to demonstrate compliance with 15A NCAC 2D .0524 NSPS, Subpart 000, of emission sources J 1,
C3, and C4. Jason Conner,Environmental Director at Hedrick Industries was also present and concurrently
performed the test; he is VE current-certified through ETA(#395892, exp. 12/8/2011)
After meeting Mr.Conner at the scale house, we drove to the location of the portable plant where the sources
were to be tested. This site was— 1.3 miles SE into the quarry from the scale house. The facility's permitted
maximum production rate is 12,000 tons/day, and the target process rate for this test was 300 tons/hour.Mr.
Conner verbally confirmed that this was the rate the plant was operating. The weather conditions were partly
cloudy skies and—78T at the initiation of the testing,with partly cloudy skies and—80OF at the end of the
test. This Method 9 test was comprised of one 30-minute test period for each source, with compliance being
based on the average of 5 six-minute averages. Since there was multiple-point testing, up to three points
could be read at the same time, as long as none of the three readings exceeded applicable opacity standards
(per NSPS Subpart 000).

The 30-minute run began at 10:30AM, ended at 11:00AM, and consisted of emissions from"jaw"J1,as well as
the drop points off conveyors C3 and C4.A front loader frequently dumped material into the grizzly feeder(172)
for processing, with the 350 Cat C9 engine(G4)being the energy,source. Mr. Conner told me that the short C4
conveyor is normally not operated and is just used as an"emergency" if C3 gets overloaded. There are wet
suppression points at the base of C4 and at the drop off point of C3.
I performed a 30-minute Visible Emissions Evaluation(VEE) on drop off points for C3 and C4; all readings
were 0% opacity. I also performed a concurrent VEE on J1; all of the readings were either 0% or 5% opacity.
The VE observation forms are attached to this report.
5) Current applicable specific permit conditions and limitations include:
The facility is required to comply with all NSPS requirements, including reporting, emissions limitations,
monitoring, recordkeeping,performance testing and like-for-like replacement.
a) A.8 NSPS Performance Testing-As required by 15A NCAC 2D .0524,the following performance test

VISIBLE EMISSION OBSERVATION FORM
This form is designed to be used in conjunction with EPA Method 9, "Visual Determination of the Opacity of Emissions from Stationary
Sources." Temporal changes in emission color, plume water droplet content, background color, sky conditions, observer position, etc.
should be noted in the additional information section. Any information not dealt with elsewhere on the form should also
be noted under additional information. Following are brief descriptions of the type of information that needs to be entered on the
form; for a more detailed discussion of each part of the form, refer to "Instructions for Use of Visible Emission Observation Form."
*Company Name - full company name, parent company or division or *Wind Speed - record wind speed; can use Beaufort wind scale or
subsidiary information, if necessary. hand-held anemometer to estimate.
