1. Facility Overview
Discussion/Introduction
On June 22,2022,I(Michael Koerschner)met with Mr. Wesley Shook,Operator,to conduct an annual compliance
inspection. The inspection was un-announced.
I arrived at the facility at—10:20 am and observed the asphalt plant in operation making—165 TPH asphalt-using
15%RAP- for State work [9.5C Surface].I observed the asphalt plant in operation until—1 1:10 am when I left the
site.
During my visit,visible emissions from the bagfilter exhaust appeared to be less than 10%opacity.Visible
emissions from the storage silo(while being loaded)were occasionally up to 15%opacity(blue haze)and visible
emissions from truck loadout appeared occasionally up to 20%opacity.
This facility is unique in that the bagfilter-collected dust is mechanically conveyed to a dump truck via an auger
system and then a belt conveyor. The material is wetted by sprays A previous inspection report states that they
generate 6-8 dump trucks of dust per 1000 tons asphalt produced. I confirmed with Mr. Shook that this was still an
accurate estimate of the dust generation.
Facility Contacts
The facility contacts appear to be up-to-date in IBEAM.
Facility Description
Harrison Construction Division of APAC-Atlantic, Inc.—Murphy Asphalt Plant is a hot mix asphalt batch plant,
subject to NSPS Subpart I,with a maximum rated capacity of 300 tons per hour. The plant started production this
season in early May and has made 10,140 tons asphalt year-to-date. Recent upgrades to this facility include new
ductwork on the ID side of the bagfilter fan, improvements to the aggregate elevator, and two new asphalt storage
silos. Both silos are nominally rated at 200 tons asphalt storage but,according to Mr. Shook,they only utilize about
170 tons/silo.
The facility is permitted for the following operations air emission sources/air cleaning devices and appurtenances
described below:

2. Emission Sources and Regulatory Review
Compliance with specific permit conditions and limitations
Specific Condition 3: Particulate Control Requirement-Hot Mix Asphalt Plants
Maximum allowable particulate emission rate from the facility are limited to 60 pounds per hour(at a process rate of
300 tons asphalt/hour); visible emissions from any stack, vent, or any fugitive emission is limited to 20%opacity;
and,the facility must be equipped with a scavenger process dust control system for the processing of the aggregate.
This facility is subject to NSPS Subpart I which is a concentration limit but is generally more stringent than 2D
.0506. The results of the 10/08/2015 stack test indicates compliance with the particulate limits for the aggregate -
dryer.
Specific Condition 4: Sulfur Dioxide Requirement
This condition applies to the combustion sources and limits sulfur dioxide emissions to 2.3 pounds per million Btu.
Compliance with this condition was established by calculation during the last permit renewal. The fuel oil
combusted(recycled No.4)at this facility is generally less than 0.5%Sulfur and permit-limited to less than 1.0%
Sulfur. I reviewed the fuel analyses for each drop received this year and the highest sulfur content was 0.22% Sulfur
by weight. Continued compliance is expected.
Specific Condition 5: New Source Performance Standards
The facility is to comply with the NSPS emission limitations of 90mg/dscm (0.04 gr/dscf)particulate and 20%
opacity. The results of the 10/08/2015 stack test indicates compliance with this condition (see Section 4 below).
Specific Condition 7: Fugitive Dust Control Requirement
This condition prohibits fugitive dust emissions from crossing the property boundary. The haul roads had been
watered and dust from the haul roads was minimal. No road-generated fugitive emissions were observed.
Compliance is indicated.
Specific Condition 8: Toxic Air Pollutant Emissions Limitation and Reporting
The facility has triggered a toxics review for benzene and formaldehyde, and has modeled compliance with the
AALs. In order to demonstrate compliance,the facility has production limitations. Hourly asphalt production shall
not exceed 300 tons and annual asphalt production shall not exceed 485,000 tons. The facility keeps records to
demonstrate compliance with this condition. Asphalt production is tracked electronically and,according to Mr.
Shook,the plant never has operated near the 300 ton-per-hour rating.
Specific Condition 9: Control and Prohibition of Odorous Emissions
This condition requires the facility to restrict objectionable odors to the property. .No objectionable odors were
observed on or off the property during the inspection.
Specific Conditions 10 and 11: Synthetic Minor Limitation and PSD Avoidance
In order to avoid Title V and PSD applicability,the facility has requested emission limitations on SOz,NOx and CO
to remain a synthetic minor source. In order to demonstrate compliance with these limits,the facility has an annual
production limitation of 485,000 tons(the same as that listed in Specific Condition 8), as well as a limitation of
1.0%sulfur content by weight of the recycled No. 4 fuel combusted in the dryer. The sulfur content of the highest
load of fuel delivered was 0.22% Sulfur by weight. In addition,the facility must perform annual inspections of the
control devices to ensure that they are operating properly to control particulate matter emissions. All records
indicate compliance with the emission limitations. The last inspection of the bagfilter system (including knock-out
box)took place on May 2,2022. I reviewed the inspection records.
Specific Condition 12: Vendor Supplied Recycled Fuel Oil Requirement
The facility is permitted to use recycled fuel oil that meets the specifications set forth in the permit. The facility
must maintain analytical records of the recycled fuel oil, as well as the amount of fuel oil combusted at the facility.
An annual report is also required summarizing the analytical testing results as well as the annual usage of recycled
fuel oil. I reviewed the fuel oil records. The facility has received 3 loads(-19,000 gallons)of recycled No.4 fuel oil

this season and included the required analyses. Sulfur contents of the loads were 0.17%, 0.18%and 0.22%. All
records and reports are up to date and indicate compliance with this condition.
Specific Condition 13: Toxic Air Pollutant Emissions Limitation Requirement
The facility has demonstrated that their emissions of various toxic air pollutants are below the level that requires a
permit to emit these toxics. As long as the facility does not go over the annual production limitation set forth in
Specific Condition 8,emissions of these pollutants will remain below the TPER.
Recordkeeping and Reporting Requirements Review
The facility is required to maintain records of asphalt production, control device I&M,and recycled fuel usage with
fuel certifications. The facility is required to report asphalt production and recycled fuel usage with fuel
certifications annually. The required records are maintained at the facility and the last annual report received on
O1/14/2022 indicated compliance. In 2021,the facility produced 32,852 tons of asphalt.
Insignificant Sources Listing
Source Notes
I-I - One No.2 fuel oil-fired asphalt tank heater(1.38 Observed in operation. Currently combusting only
million Btu per hour heat input) ;propane. No.2 fuel oil is no longer burned at this site.
There are two fuel oil storage tanks at this facility. The
I-2-fuel oil storage tanks facility no longer uses No.2 fuel oil. There are two (2)
15,000 gallon No.4 fuel oil tanks. These tanks are new.
3. Compliance History Review
The facility has had no other documented violations in the past five years.
4. Stack Test Review
The facility was required to perform Methods 5,9, and 202 stack tests for this permit cycle with the results due to
this office within 60 days of the re-start. The results of the required stack tests,performed on October 8,2015,while
producing 236 tons per hour and combusting recycled No.4 fuel, are shown in the table below:
