• Directions: Take 19123 north out of Asheville to 19 E to Burnsville. Go south on Hwy 197 for
approximately 8 miles. Quarry will he on the right.

• Facility Overview:
• Safety: Required equipment-Hard hat, Safety Shoes,Eye and Hearing Protection
• Discussion:
On August 07,2020,I, Bob Graves traveled to the facility to conduct an annual compliance
inspection. I met with Mr.Chuck McCrary, Supervisor. Mr. McCrary said their business is
very slow. I conducted a records review and toured the rock crushing plant with Mr. McCrary.
During the inspection,the crushing and wash plant was observed not in operation. The.haul
roads were wet for dust control. No dust concerns were observed. The facility is maintaining a
copy of their current air permit,equipment list and equipment flow diagram on site. The
facility operates all of equipment on electricity; except for the jaw crusher. The jaw crusher is
driven by a 280 HP diesel-fired engine. The engine was purchased in 2014. The engine is
subject to NSPS, Subpart IIII as well as NESHAP, Subpart ZZZZ. However,compliance with
the NESHAP is established through compliance with the NSPS. The facility is using good
maintenance and work practices maintaining their engine.
• Facility Contacts: No changes.
• Facility Description: This is a rock crushing plant in Burnsville.

• Permit Conditions:
2D 0510 -Particulates from Sand, Gravel, or Crushed Stone Operations -This regulation requires that all
fugitive process dust emissions from crushers,conveyors, screens and transfer points be reduced to a
minimum. (See permit for full averaging times)During the inspection, I did not observe any VE dust
concerns. Compliance is indicated.
2D 0521 - Control of Visible Emissions(VE) -the visible emissions from the facility shall not be more
than 40 percent opacity when averaged over a six-minute period for sources manufactured as of July 1,
1971. For sources manufactured after July 1, 1971,visible emissions shall not be more than 20 percent
opacity. During the inspection,the facility was not in operation. I did not observe any VE concerns.
Compliance is indicated.
NSPS Rock Quarry:
2D 0524-New Source Performance Standards, Subpart 000 -This regulation applies to equipment
manufactured after August 31, 1983 and stipulates that fugitive emissions from crushers may not exceed
15% opacity,that any transfer point on belt conveyors screening_operations or any other affected facility
must not exceed 10%opacity, and that wet processes may not exceed 0%.
All equipment in table one below is subject to NSPS, Subpart 000. Test dates are listed where
applicable. Sources that handle material that is saturated with water are exempt from testing. It appears
that all testing requirements for all NSPS subject equipment at this facility have been met. Compliance is
indicated.

Per Mr. McCrary,none of the equipment on site was constructed,modified or reconstructed after April
22, 2008; therefore,the facility is not currently required to perform monthly inspections of the wet
suppression nozzles/spray bars. During the inspection, no violations were observed. Compliance is
indicated.

ES-Engine is subject to NSPS, Subparts IIII, and NESHAP, Subpart ZZZZ(RICE MACT) as
referenced below:
a. NSPS-This facility is subject to New Source Performance Standards (NSPS), Subparts IIII.
Subpart IIII applies to the diesel-fired Compression Ignition(CI) engine that drives the jaw
crusher.
b. NESHAP -The diesel-fired engine that drives the jaw crusher at this facility is subject to
National Emission Standards for Hazardous Air Pollutants(NESHAP), Subpart ZZZZ for
stationary reciprocating internal combustion engines(RICE). For compliance see below:
ES-Engine: Note: Compliance with NESHAP, Subpart ZZZZ is established through compliance with
NSPS, Subpart IIII regulations listed below:

NSPS Subpart HU - For the following equipment,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 60, Subpart indicated below, and including
Subpart A "General Provisions."
40 CFR 60, Subpart IIII
ES-Generate(ID No. ES-Engine) "Standards of Performance for Stationary
Compression Ignition Internal Combustion Engines(CI
ICE)"
• Emission Standards: Stationary Cl ICE must be operated and maintained the stationary Cl ICE
per the manufacturer's written emission-related instructions to achieve the emission standards as
required in 40 CFR 60.4204 and 60.4205 over the entire life of the engine.
Facility appears to be operating and maintaining the stationary Cl ICE per
manufacturing standards to achieve the required emission standards. Compliance is
indicated Preventive Maintenance activities (oil changes, etc) are conducted every 250
hours of operation. Air filters are changed every 2-3 days of operation. Compliance is
indicated.
• Fuel Requirements:NSPS requires the use of fuel with 15 ppm sulfur max and a minimum cetane
index of 40 or a maximum aromatic content of 35 percent by volume.
The facility purchases Ultra low sulfur diesel fuel (15 PPAI). Compliance is indicated.
• Monitoring Requirements: If the non-emergency stationary CI ICE is equipped with a diesel
particulate filter to comply with the emissions standards listed above,the diesel particulate filter
must be installed with a backpressure monitor that notifies the Permittee when the high
backpressure limit of the engine is approached. [60.4209(b)]
This engine does not have a particulate filter on the exhaust. The engine does have a
non-resettable electronic hour meter.
