Intent:
Promote clean air and mitigate climate change by minimizing emissions of net CO2e, Criteria Air Pollutants and Hazardous Air Pollutants from thermal conversion processes.
Requirements:
- Demonstrate net CO2e emissions below 850 lbs CO2e/MWH (1)
- Demonstrate that Criteria Air Pollutant(2) emissions meet the levels in the table below:
- Demonstrate total VOC + Hazardous Air Pollutant + Hydrogen Sulfide (H2S) + Ammonia (NH3) (3) levels below 0.1 lbs/MWh
Criteria Air Pollutant limit Table (lbs/MWh)
NOx: <1 lb/MWh
SO2: <1 lb/MWh
PM 2.5-10: (4)
Daily Basis 10 mg m-3
Half-hour basis: 30 mg m-3
Emissions should be continuously measured and verified by the local air quality management regulator.
Strategies:
- Install flue gas continuing monitoring equipment
- Install best available control technologies
- Utilize biogas or landfill methane for co-firing
- Remove potentially hazardous materials from the waste stream before combustion
Notes
“Thermal conversion processes” include various forms of incineration, gasification and pyrolysis technologies
- 2013 Clean Power Plan emissions requirements for combined cycle natural gas = 890 lbs CO2 – MWH (403 g/kWh)
- Criteria Air Pollutants are: NOx, SO2, O3, PM 2.5-10
- HAPs include benzene, naphthalene, 1,3-butadiene, Polycyclic aromatic hydrocarbons (PAH); Hydrogen Fluoride (HF) and Hydrogen Cyanide (HCN); Mercury, Lead, Chromium, and other heavy metals.
(Based on (Directive 2010/75/EU)
Consider making this Credit #2 to put it next to Credit #1 that also addresses thermal conversion.
