Inspection Report:

1) Location: Vulcan Construction Materials, LLC -North 321 Quarry is located at
3540 Blowing Rock Blvd in Lenoir, NC, Caldwell County.
Directions: From Lenoir,travel north on Hwy 321 for about 4 miles towards
Patterson and continue north for another 3 to 4 miles past the Patterson turn-off(Hwy
268). The facility is located on the right.
2) Facility Overview: Vulcan Construction Materials, LLC -North 321 Quarry is a rock
quarry producing crushed stone for the construction industry. This facility is
permitted under Air Permit No. 08589R06, effective from November 8, 2019, until
December 31, 2025. Last compliance inspection conducted on January 29, 2019 by
Richard Morris.
Safety: Hard Hat, safety shoes, hearing protection
Current throughputs: Employees, Hours of operation, production numbers
Not operating
Pre-inspection Conference: On August 8, 2020, Richard Morris called and spoke
with facility contact Jason Hutchens. We discussed the following:
a) I informed Mr. Hutchins that because of COVID-19 pandemic,NCDAQ is not
physically inspecting facilities. We are conducting Partial Compliance
Evaluations remotely to fulfill our compliance commitments. I requested he
answer some questions about production and record keeping which he was
glad to answer.
b) This facility is closed and currently not operating with no plans to operate in
the foreseeable future. No equipment is located at this site.
Process Description: (from AP-42)
Rock and crushed stone products generally are loosened by drilling and blasting,then are
loaded by power shovel or front-end loader into large haul trucks that transport the
material to the processing operations. Techniques used for extraction vary with the
nature and location of the deposit. Processing operations may include crushing,
screening, size classification, material handling, and storage operations. All of these
processes can be significant sources of PM and PM-10 emissions if uncontrolled.
Quarried stone normally is delivered to the processing plant by truck and is dumped into
a hoppered feeder, usually a vibrating grizzly type, or onto screens. The feeder or screens
separate large boulders from finer rocks that do not require primary crushing,thus
reducing the load to the primary crusher. Jaw, impactor, or gyrator crushers are usually
used for initial reduction. The crusher product, normally 7.5 to 30 centimeters (3 to 12
inches) in diameter, and the grizzly throughs (undersize material) are discharged onto a
belt conveyor and usually are conveyed to a surge pile for temporary storage, or are sold
as coarse aggregates. The stone from the surge pile is conveyed to a vibrating inclined

screen called the scalping screen. This unit separates oversized rock from the smaller
stone. The undersize material from the scalping screen is considered to be a product
stream and is transported to a storage pile and sold as base material. The stone that is too
large to pass through the top deck of the scalping screen is processed in the secondary
crusher. Cone crushers are commonly used for secondary crushing (although impact
crushers are sometimes used), which typically reduces material to about 2.5 to 10
centimeters (1 to 4 inches). The material (throughs) from the second level of the screen
bypasses the secondary crusher because it is sufficiently small for the last crushing step.
The output from the secondary crusher and the throughs from the secondary screen are
transported by conveyor to the tertiary circuit, which includes a sizing screen and a
tertiary crusher. Tertiary crushing is usually performed using cone crushers or other
types of impactor crushers. Oversize material from the top deck of the sizing screen is
fed to the tertiary crusher. The tertiary crusher output, which is typically about 0.50 to
2.5 centimeters (3/16th to 1 inch), is returned to the sizing screen. Various product
streams with different size gradations are separated in the screening operation. The
products are conveyed or trucked directly to finished product bins, open area stockpiles,
or to other processing systems such as washing, air separators, and screens and classifiers
(for the production of manufactured sand).
Inspection: No site visit was conducted in associated with this Partial Compliance Evaluation
(PCE) due to the COVID-19 pandemic. The following observations are referenced from the
most recent site visit (conducted on January 29, 2019).

Stipulation Review:
A.3 PARTICULATE CONTROL REQUIREMENT - As required by 15A NCAC 2D
.0510 'Particulates from Sand, Gravel, or Crushed Stone Operations," the
following requirements apply:

a. The Permittee of a sand, gravel, recycled asphalt pavement(RAP), or crushed
stone operation shall not cause, allow, or permit any material to be produced,
handled,transported, or stockpiled without taking measures to reduce to a
minimum any particulate matter from becoming airborne to prevent exceeding the
ambient air quality standards beyond the property line for particulate matter, both
PM10 and total suspended particulates.
b. Fugitive dust emissions from sand, gravel,RAP, or crushed stone operations shall
be controlled by 15A NCAC 2D .0540 'Particulates from Fugitive Dust Emission
Sources."
c. The Permittee of any sand, gravel, RAP, or crushed stone operation shall control
process-generated emissions:
i. From crushers with wet suppression(excluding RAP crushers); and
ii. From conveyors, screens, and transfer points
such that the applicable opacity standards in 15A NCAC 2D .0521 Control
of Visible Emissions," or 15A NCAC 2D .0524 "New Source Performance
standards"are not exceeded.
Not observed. Not operating (in compliance).
A.4 2D.521 —Visible Emissions 20%. Not observed. Shut down.
A.5 2D.521 —Visible Emissions 40%. Not observed. Shut down.
A.6 2D.524—NSPS. In compliance. For the nonmetallic mineral processing
equipment (wet material processing operations, as defined in 60.671, are not
subject to this Subpart) including Conveying Operations (ID No. ES-Convey),
Crushing Operations (ID No. ES-Crush) and Screening Operations (ID No. ES-
Screen), the Permittee shall comply with all applicable provisions, including the
notification,testing, reporting, recordkeeping, and monitoring requirements
contained in Environmental Management Commission Standard 15A NCAC 2D
.0524 "New Source Performance Standards" (NSPS) as promulgated in 40 CFR
