HOLMAN ENVIRONMENTAL QUALITY Director August 23, 2016 Mr.Howard P.Brown,Jr. Executive Vice President&COO Triangle Brick Company-Wadesboro 6523 NC Highway 55 Durham,North Carolina 27713-9436 Subject: Triangle Brick Company-Wadesboro,Facility ID 0400043,Tracking No. 2016-213ST Wadesboro,Anson County,North Carolina,Air Permit No. 08179T08 Protocol for Emissions Testing of Brick Tunnel Kiln(ID No.K-2) Filterable Particulate(PM),Hydrogen Chloride(HCl)and Hydrogen Fluoride(HF) Test To Be Performed by Environmental Resources Management(ERM) Test Date: Week of September 12,2016 Dear Mr.Brown: The North Carolina Division of Air Quality(DAQ)has reviewed the subject protocol submittal for emissions testing of brick tunnel kiln K-2. The proposed testing is acceptable to demonstrate compliance with the applicable emissions standards. The source to be tested is a natural gas/No. 2 fuel oil/No. 6 fuel oil-fired Brick Tunnel Kiln(29.0 tons per hour material output rate,42.8 million Btu per hour heat input rate). Brick tunnel kiln K-2 is controlled by dry limestone adsorber(DLA)CD-K2. Testing will be performed at the CD-K2 exhaust stack during normal production. The standard that applies to K-2 is 15A NCAC 2D .1109112(J) Case-by-Case MACT for Brick Manufacturers. Permit Condition 2.1.A.4.b lists the Case-by-Case MACT limits for Filterable PM and HCl-equivalent. K-2 is also subject to 15A NCAC 2D .1100 Toxic Air Pollutant Emission Limitation and Requirements in permit section 2.2(A)(2). The table below lists the pollutants and proposed test methods. Brick Tunnel Kiln K-2—Pollutants and Test Methods EPA Target Method Run Time Standard Emissions Limit ■ Volumetric Flow Rate 1 2 3A 3 runs,60 minutes each ■ Molecular Weight and 4 Concurrent with Methods --- --- Moisture Content 5/26A ■ Filterable Particulate(PM) See permit condition ■Hydrogen Chloride(HCl) 15A NCAC 2D .1109 2.1.A.4.b ■Hydrogen Fluoride(HF) 5/26A 3 runs,60 minutes each 112(J) Filterable PM 0.17 lb/ton ■Reported as Hydrogen HCl-equivalent 9.455 lb/hr Chloride-equivalent 15A NCAC 2D .1100 Toxic air pollutants (HCl equivalent) See Section 2.2(A)(2) Note: The tester must verify the absence of cyclonic flow as described in Section 11.4 of U.S.EPA Method 1.

Brown, Jr. - Executive Vice President&COO August 23, 2016 Page 2 (Triangle Brick Company-Wadesboro, Kiln K-2 -HCl and HF Emissions Testing) ERM proposes using a combined EPA Method 5/26A sampling train for PM, HCI, and HF. The proposed combined method is acceptable provided the EPA Method 26A Teflon filter support is used(the alternative Teflon probe liner, cyclone, and filter holder are not acceptable). Also the probe and filter temperature requirements of both EPA Method 5 and Method 26A must be met. Please note that the detection limits for some of the proposed methods are based on actual source parameters. No estimated detection limits are listed in the protocol. Therefore,the responsibility will remain with Triangle Brick and the tester to ensure that the minimum method detection limits will be low enough to demonstrate compliance with the applicable emissions limits. The result cannot be reported as zero. The result must be reported as less than the method detection limit determined from the test. Note that audit sample analysis is required for EPA Method 26A. ERM has submitted an audit sample order request. The sample must be present for inspection on request during the test period. For additional information please see this EPA web page httpJ/www.epa.gov/ttn/eme/email.html#audit. The target process rate for testing is 29 tons per hour. Please note representative testing is considered to be 90%or above maximum production rate. Additional testing or an adjustment to the permitted maximum production rate may be required if the test period process rate is less than the 90%. The test period process rate information must be included in the report with the applicable control system operation parameters(i.e. source and grade of limestone,pressure drop and limestone feed rate). Approval of the proposed testing methods does not exempt the tester,in any way, from the minimum requirements of the applicable test methods. Any deviations from the applicable methodologies not specifically addressed in this letter remain subject to the approval of the Division of Air Quality. If there are questions concerning this matter,please contact me at(919)707-8415 or greg .og nealkncdenr.gov. Sincerely, Thomas G.
