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 classification has oust changed from Title V to
Small,with no reporting requirements. 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 requirements are being met. Consider this
facility as being in compliance with all NCDAO regulations.
The facility now has the following permitted equipment:

10. AVOIDANCE CONDITION FOR AREA SOURCES SUBJECT TO 40 CFR 63 Subpart JJJJJJ(6J1-In
accordance with 15A NCAC 2Q.0317,the Permittee is avoiding applicability of 40 CFR 63 Suboart
JJJJJJ(6J)"Industrial,Commercial,and Institutional Boilers Area Sources."The Permittee is permitted to
operate a natural gas/No.2 fuel oil-fired boiler(ID No.EU 1.1).Per 40 CFR 63.11195(e),this source is
exempt from this Subpart because it is defined as a gas-fired boiler in 40 CFR 63.11237.In order to
maintain this exemption,the Permittee is allowed to fire liquid fuel only during periods of gas curtailment,
gas supply interruptions,startups,or for periodic testing on liquid fuel(periodic testing not to exceed a
combined total of 48 hours during any calendar year).
a. The Permittee shall maintain records that document the time periods when liquid fuel is fired and
the reasons the liquid fuel is fired.
b. If the Permittee fires liquid fuel for reasons other than gas curtailment,gas supply interruptions,
startups,or for periodic testing on liquid fuel,the Permittee is no longer exempt from Subpart
JJJJJJ(6J).As required by 40 CFR 63.11225(g),the Pennittee must provide notice within 30 days
of the fuel switch. The notification must identify:
i. The name of the owner or operator of the affected source,the location of the source,the
boiler(s)that have switched fuels,and the date of the notice.

As required by 40 CFR 63.11210(h),the Permittee must demonstrate compliance within
180 days of the effective date of the fuel switch.
The Boiler ID No. EU 1.1 is a 500 HP Cleaver Brooks was operating during time of inspection
burning propane. This boiler runs 2417, between low fire and high firing, as needed They
usually shut this boiler down from November through Mid-March (wintertime) as there is no
paving of asphalt during this time. No liquid fuel has been burned since T19 issuance.
Zero visible emissions were observed for ALL emissions sources facility-wide. Compliance with
2D.0521 was indicated facility-wide for ALL emission sources.
Inspection Results
The facility had no asphalt processing or storage from 2009 to December 2012. With the T18 permit
revision 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.
With the last permit revision, T19, the facility classification went from a Title V facility to a Small
facility. 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 eas. The boiler was operating at the time of inspection burning
propane. The boiler is rated for 200 psi steam, but is limited to 150 psi. 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 Ioadout nor railcar loadout was occurring at the time of inspection. There was no opacity
noticed nor objectionable odors detected during the time of inspection.
Permit Recordkeepine and Revortine Requirements
Most of the facility recordkeeping and reporting requirements in T18 are now gone in T 19. The only
recordkeeping requirement now is for 6J avoidance, as follows:
AVOIDANCE CONDITION FOR AREA SOURCES SUBJECT TO 40 CFR 63 Subpart JJJJJJ W) In
accordance with 15A NCAC 2Q.0317,the Permittee is avoiding applicability of 40 CFR 63 Subpart
JJJJJJ(0)"Industrial,Commercial,and Institutional Boilers Area Sources."The Permittee is permitted to
operate a natural gas/No.2 fuel oil-fired boiler(ID No.EU 1.1).Per 40 CFR 63.11195(e),this source is
exempt from this Subpart because it is defined as a gas-fired boiler in 40 CFR 63.11237.In order to
maintain this exemption,the Permittee is allowed to five liquid fuel only during periods of gas curtailment,

gas supply interruptions,startups,or for periodic testing on liquid fuel(periodic testing not to exceed a
combined total of 48 hours during any calendar year).
a. The Permittee shall maintain records that document the time periods when liquid fuel is fired and
the reasons the liquid fuel is fired.
b. If the Permittee fires liquid fuel for reasons other than gas curtailment,gas supply interruptions,
startups,or for periodic testing on liquid fuel,the Permittee is no longer exempt from Subpart
JJJJJJ(0).As required by 40 CFR 63.11225(g),the Permittee must provide notice within 30 days
of the fuel switch. The notification must identify:
i. The name of the owner or operator of the affected source,the location of the source,the
boiler(s)that have switched fuels,and the date of the notice.
The date upon which the fuel switch occurred.
As required by 40 CFR 63.11210(h),the Permittee must demonstrate compliance within 180 days of the effective date of
the fuel switch.
The facility has had no liquid fuel burning since issuance of T19.
There are now no reporting requirements.
