SUBJECT: S.T.Wooten Pittsboro Asphalt Plant
Total Particulate Matter Testing Protocol for Pittsboro Asphalt Plant
Pittsboro,Chatham County,North Carolina
Facility ID: 1900023,Air Quality Permit No.01887R21
Proposed Test Date:April 19,2018
Tracking No.2018-082ST
Dear Mr.Washburn:
The North Carolina Division of Air Quality(DAQ)has reviewed the protocol submittal form(PSF)for the
emissions testing of the Pittsboro asphalt plant. The test methods are acceptable as proposed. TRC Environmental
proposed three 60-minute EPA Method 5/202 runs for the total particulate matter(PM)determination.
The emission source to be tested is a 250 ton per hour capacity drum type hot mix asphalt plant consisting of
aggregate dryer/mixer ID No.ES-14ES1 controlled by horizontal cyclone CD-14-HC1 in series with baghouse CD-
14-BH1.The proposed production rate for testing of 250-280 tons per hour is acceptable.
40 CFR 60 Subpart I Standards of Performance for Hot Mix Asphalt Facilities applies to ES-14ES1 at the Pittsboro
plant and limits filterable PM to 90 milligrams per dry standard cubic meter and visible emissions to 20%opacity.
15A NCAC 2D .0506 Particulates From Hot Mix Asphalt Plants also applies and limits total PM based on actual
production rate.
Any deviations from the proposed sampling program remain subject to approval by DAQ. Approval of the proposed
methods does not exempt the tester from the minimum requirements of the testing methodologies nor does it exempt
S.T.Wooten from any regulatory requirement. If you have any questions,please contact me at(919)707-8413 or
[e-mail].
