Box 129 Merry Hill,NC 27957-0129 Subject: Avoca LLC—(841 Avoca Farm Road) Merry Hill,Bettie County,North Carolina Protocol for Particulate Matter(PM),Hydrogen Chloride (HCI), Carbon Monoxide (CO), and Mercury(Hg)Emissions Testing Biomass Boilers ES-BB1 and ES-BB2 Proposed Test Date: December 13,2022, To Be Performed by Integrity Air Monitoring,Inc. Facility ID 0800044,Air Permit No. 01819T53,Tracking No. 2022-261ST Dear Mr. Conner: The North Carolina Division of Air Quality(DAQ)has reviewed the protocol submittal form(PSF)for the emissions testing of biomass boilers ES-BB 1 and ES-BB2. Integrity Air Monitoring has proposed EPA Method 5 for particulate matter(PM),EPA Method 26A for hydrogen chloride(HCl),EPA Method 10 for carbon monoxide(CO), and EPA Method 30B for mercury(Hg). The proposed testing is acceptable for demonstrating compliance with the applicable regulations. ES-BB 1 and ES-BB2 are two biomass/bio-based solids-fired boilers(24 million Btu per hour maximum permitted heat input rate each) controlled by bagfilter CD-BB 1BH. 15A NCAC 2D .0503 Particulates From Fuel Burning Indirect Heat Exchangers and 40 CFR 63 Subpart DDDDD National Emissions Standards for Hazardous Air Pollutants for Industrial, Commercial, and Institutional Boilers and Process Heaters apply to the biomass boilers. The emissions limits and regulations are shown in the table below.

Note: As proposed sampling will be performed via a combined Method 5/26A sample train. Thus,tester must meet the more restrictive method requirements of each of the two methods(i.e.,temperatures and sample volumes).

The proposed test process rate for boiler ES-BB 1 and ES-13132 is approximately 21.6 MMBtu/hr each. The applicable test period monitoring parameters should also be included in the final report. The proposed testing is acceptable for demonstrating compliance with the applicable regulations. Approval of the proposed methods does not exempt the tester from the minimum requirements of the applicable test methods. Any deviations from the applicable methods remain subject to approval by DAQ.
