We hope that you have enjoyed the benefit of our initiative to provide a single inspector capable of
handling multiple areas of environmental compliance at your facility. The results of each applicable
inspection area and any associated response actions or necessary corrective measures are detailed in the
Division specific areas of the attached report. If there are no notes or comments under each Division
header, you may assume compliance with that particular Division's rules and regulations at the time of
inspection. Should violations be noted in the attached report, you may receive separate enforcement related

Inspection Summary.
The facility has two outfalls that are not labeled correctly and one Is not shown in the correct location an the site map,
these Issues should corrected and the analytical results should note the sample point ID. The SP3 plan should Include a
site specific BMP summery that summarizes In words the the BMP's on the site. The plan also needs to Include a spifl
prevention and resporlce plan within the SP3 plan that dearly outlines the measures used to prevent spills and the process
for dealing with spills if they occur. The site map Included In the plan needs more detail and should include flow patterns ,
permit and property boundaries, SMPs such as the banns sediment pits and the location of all on site equipement. Lastly
the fructose tank on site requires secondary contalnmenLif that can't be accomplished the lank should be removed from this
property

(II) FACILITY DESCRIPTION: S.T. Wooten Corporation — Pittsboro Plant (Plant #211) is a Hot Mix Asphalt (LIMA) rotary
double barrel drum plant. The facility has 3 full-time employees on site and operates 8-10 hours/day, 5 days/week year
round. Occasionally when demand is high the plant may operate on a Saturday.
(Iip INSPECTION SUMMARY: On May 31, 2016, I Thad Valentine with DLR along with Gary Perlmutter DAQ Chang
Zhang DWR and Eric Swope DWM as of a Multi Media inspection visited S.T. Wooten Plant #211 for an air permit
compliance inspection. Upon arrival the facility was in full operation with several trucks receiving loads. I met with Mr.
James Washburn in the parking lot and we reviewed the facility permit stipulations. Mr. Washburn showed me the facility
permit and -all required records, -which appeared complete and up to date with the most recent I&M logbook entries made on
March 24, 2016. Mr. Washburn informed me that the plant runs solely on natural gas, and had stopped receiving recycled
asphalt shingles this season. Overall the facility appeared to be operating properly from an Air Quality standpoint per the
details below.
(IV) Safety note: required personal protective equipment includes hard hat, safety glasses, hearing protection and steel -toed shoes
and safety vest. Be aware of vehicles entering and leaving the facility

fugitive emissions, will not exceed TPERs listed in 15A NCAC 2Q .0711. See permit for list.
Appeared to be in compliance - the facility appeared well run and maintained from an air quality standpoint.
(VII) GENERAL PERMIT CONDITIONS:
B.5 REPORTING REQUIREMENT - Any changes that would result in previously unpermitted, new, or increased emissions
must be reported to DAQ.
Appeared to be in compliance - Mr. Washburn indicated that no such changes have been made; only the removal of recycled

Of the air permit at the site.
Appeared to be in compliance - Mr. Washburn presented a copy of Air Permit No. 018871120 during my inspection.
B.15 CLEAN AIR ACT SECTION 112(r) REQUIREMENTS - Pursuant to 40 CFR Part 68 "Accidental Release Prevention
Requirements: Risk Management Programs Under the Clean Air Act, Section 112(r)," if the Permittee is required to develop
and register a risk management plan pursuant to Section 112(r) of the Federal Clean Air Act, then the Permittee is required to
register this plan with the USEPA.

All sources were verified and observed in operation during the inspection with the following exception: one of
the two fuel oil storage tanks had been emptied as the facility no longer uses recycled fuel oil. While looking
through the exempt source records it was discovered that one of the asphalt tanks had a 30,000 gallon
capacity instead of the 20,000 gallon shown on previous records. This should be corrected in the next permit
revision.
