Subject: Buncombe County Landfill II
Alexander,Buncombe County,North Carolina,Air Permit No. 10398T01
Facility ID 11-00542, Tracking No. 2017-097ST
Nitrogen Oxides, Carbon Monoxide, Volatile Organic Compounds and Formaldehyde
Emissions Testing of Landfill Gas-fired Engine/Generator Set ES-Cl (SN: 1021619)
Performed April 4,2017 by GEL Engineering,LLC
GEL Engineering performed nitrogen oxides(NO.), carbon monoxide(CO),volatile organic compounds
(VOC),and formaldehyde(CH2O)emissions testing on the Jenbacher(Model J-420 GS-1382,
manufactured 2011)landfill gas-fired spark ignition generator unit(1,466 kW, 1,966 horsepower), ES-G1.
The emissions testing results are acceptable. The formaldehyde testing was requested by NC DAQ via
letter dated August 19,2016.
40 CFR 63 Subpart ZZZZ National Emission Standards for Hazardous Air Pollutants for Reciprocating
Internal Combustion Engines(RICE)requires that the facility comply with 40 CFR 60 Subpart JJJJ
Standards of Performance for Stationary Spark Ignition Internal Combustion Engines. The facility was
operating under permit No. 10398T01 during testing.
Permit condition 2.1.B.5.a establishes State BACT(SB3),as defined in North Carolina General Statute 62-
133.8(g)Renewable Energy and Energy Efficiency Portfolio Standard(REPS). Per the current permit,the
SB3 emission limits for CO,NO,,, and VOC resulting from biomass combustion are the same as the 40
