General Facility Summary
The facility can be reached by taking Hwy. 70 through Morehead City. Before taking the bridge to
Beaufort, veer right into the State Ports. The plant is on the right; the office is by the parking lot.
An escort is now required to drive onto the port. In addition to standard safety gear, long sleeves are
required here. The facility used to have a permitted roofing operation in another building. That
process shutdown around 1996. The facility has been repairing and rebuilding since being
bought from the previous owners in 2010, and only began asphalt storage and distribution in
January 2013. Now, they are only being used as an asphalt distribution terminal with no
processing. On March 10, 2014, they switched their primary fuel from ultra-low sulfur No. 2
fuel oil to LP (propane) gas. Zero visible emissions were observed for all emission sources, and
all required recordkeeping and reporting requirements are being met. Consider this facility as
being in compliance with all NCDAQ regulations.
Comments for each Permit Specific Condition are written in Bold Italics. See Inspection Results
beginning on page 17.

e. The Permittee shall submit a summary report,acceptable to the Regional Air Quality Supervisor,of
monitoring and recordkeeping activities postmarked on or before January 30 of each calendar year for the
preceding six-month period between July and December and July 30 of each calendar year for the

i. The monthly sulfur dioxide emissions for the previous 17 months. The emissions must be calculated
for each of the 12-month periods over the previous 17 months;
ii. The monthly quantities of natural gas,No.2 fuel oil,No.4 fuel oil,cutter stock,No. 5 fuel oil,and No.
6 fuel oil consumed,and amount of oxidized asphalt produced for the previous 17 months;

determined by multiplying the total amount of each type of HAP-containing material consumed during the
month by the HAP content of the material. Calculations and the total amount of HAP emissions and
individual HAP emissions shall be recorded monthly in a logbook(written or electronic format). The
Permittee shall be deemed in noncompliance with 15A NCAC 2D.1111 if the amounts of HAP containing
materials or the HAP emissions are not monitored and recorded. The Permittee shall also be deemed in
noncompliance with 15A NCAC 2D.1111 if the HAP emissions exceed the above limits.
Because the facility is not processing any asphalt, but is only storing and distributing asphalt and
using propane in the boiler, very low HAP emissions are occurring. The facility continues to
monitor, record and report their HAP emissions as required. Compliance is indicated.

Inspection Results
I was escorted during the inspection by Mr. Callahan, Plant Manager. The plant has not performed
oxidation since August of 2007.
The facility had no asphalt processing or storage from 2009 to December 2012. With the most recent
permit revision (T18) on 6/26/14, the preheaters, converters, and thermal oxidizer have all been removed
from the permit. Up until then, they had the equipment to process (oxidize the asphalt by bubbling
heated air through it, however, that the facility has done no oxidization since 2007; this process occurred
in the converters. Beginning January 2013, the facility started as an asphalt storage and distribution
terminally only. The facility now receives asphalt by barge, about 1 to 2 times per year(about 8 million
gallons total). They heat the asphalt with the 500 hp Cleaver Brooks boiler only from about March
through October(about 280-300 F). The facility converted from No. 2 ultra low sulfur fuel oil to LP
gas on 3/10/14, and now burns primarily LP gas. The boiler was operating at the time of inspection.
The boiler is rated for 200 psi steam, but is limited to 150 psi, and generally runs around 70 psi. The
boiler was observed operating at 135 psi, and 0%VE. In the winter months, the asphalt is not heated, yet
the temp still maintains about 70-90F. The asphalt is then trucked out only, no railcar loading since
2007.
The facility has the following current tank storage: Asphalt in tanks 1, 2, 3, 4, 18, 19, 20, 21, 22 and
23. The facility stores ultra-low sulfur No. 2 fuel oil in Tank 25. All other tanks are empty.
No truck loadout nor railcar loadout was occurring at the time of inspection. There was no opacity
noticed nor objectionable odors detected during the time of inspection.
The parts washer is a Safety Kleen,using"Safety Kleen Premium Solvent", which is primarily
naphtha or mineral spirits. No uncovered containers, solvent cleaning rags, solvent odors etc. were
observed, indicating compliance with 2D .0958. The monthly work practice observation log is being
kept.
Permit Recordkeeping and Reporting Requirements
Records for the monthly VE observations of the boiler, tanks, and the loading racks were complete
for the period since the last inspection. All required records are being kept including the amount of
propane and No. 2 fuel oil and the % sulfur content.
The facility submitted the required semi-annual reports for 2014 (1/25/14 and 7/23/14); 2015
(1/27/15 and 7/15/15); 2016 (1/27/16 and 7/18/16); and 2017 (1/17/17). These reports indicated
compliance with all reporting requirements —no permit deviations.
Compliance History
The facility(SemMaterials, a previous owner)was assessed a civil penalty of$2,000.00 on 07/28/08
for failing to submit their emissions inventory by 06/30/08.

Slurry Pavers Compliance Inspection
3/29/17
Page 18 of 19
The facility(Owens Corning, a previous owner) was assessed a civil penalty of$1,000.00 on
07/20/06 for failing to submit their emissions inventory by 06/30/06. A request for remission was
denied on 10/13/06.
Note that the current owners, Slurry Pavers, have had no NOVs or NODS.
Facility Emissions
The facility did not perform any asphalt processing or storage from 2009 through December 2012.
IBEAM "Fees—Yearly pollutant data" shows zero emissions for the last 3 years (2010-2012)—this is
correct.
Conclusions, Comments, and Recommendations
With revision T12, Owens Corning (a previous owner)was permitted to remove Preheater 1 and
replace it with Preheater 4. The new heater has a 1.53 mmBtu/hr higher rating of 9.9 mmBtu/hr.
They also were permitted to add a third converter. Another change was the ability to burn natural
gas/propane and cutter stock. Cutter stock is a by-product of processing and has similar properties to
No. 5 fuel oil. Preheater 4 has not been installed. Although Preheater 1 was removed from the
permit, they may continue to use it and follow the old permit conditions for it until Preheater 4 is
installed. They will not operate Preheater 1 once No. 4 is installed.
With revision T13, SemMaterials became the new facility owner.
The five year renewal was revision T14.
With revision T15, SemMaterials Energy Partners became the new facility owner.
With revision T16, the facility name was changed to B1ueKnight Energy Partners (BKEP).
Slurry Pavers bought this facility from B1ueKnight Energy Partners. This ownership change is reflected
in permit revision T17. With revision T18, the facility made major changes by removing many emission
sources, as listed in the table below, that would allow them to become a Synthetic Minor facility if they
so desired:

*Note: The Permittee was subject to the New Source Performance Standards for Asphalt Processing and

No. 3 convertor (ID No. EU 4.3) was removed as part of the 6/26/14 renewal so the facility is no longer
subject to NSPS Subpart UU. As described in the Permit Application Summary,NSPS Subpart UU is only
applicable to saturators or mineral handling and storage facilities constructed/modified after November 18,
1980 and asphalt storage tanks or blowing stills constructed/modified after May 26, 1981. The boiler(ID
No.EU 1.1,20.9 million Btu/hour maximum heat input)predates NSPS Dc,as it was manufactured in 1968
(per the 2006 compliance inspection report).
The facility appeared to be in compliance with their air permit at the time of the
inspection.
