PHOENIX, January 22, 2014 – The Maricopa County Air Quality Department (MCAQD) today released its draft 2011 Periodic Emissions Inventory for Ozone Precursors. The inventory includes emission estimates for volatile organic compounds (VOC), nitrogen oxides (NOx) and carbon monoxide (CO). Emissions are calculated for both Maricopa County and the eight-hour ozone nonattainment area. Annual totals as well as season-day emissions are provided for all source categories.
The emissions inventory report will now undergo a 30-day public review period. The document is available in electronic format (PDF files) on the department’s website at: http://www.maricopa.gov/aq/divisions/planning_analysis/emissions_inventory/Default.aspx
The main body of the report consists of six chapters:
Chapter 1: Introduction (overview and summary of all source categories)
Chapter 2: Point sources (large manufacturing facilities, power plants, etc.)
Chapter 3: Area sources (widespread similar sources, such as fuel combustion, fires, etc.)
Chapter 4: Nonroad mobile sources (aircraft, locomotives, lawn mowers, tractors, etc.)
Chapter 5: Onroad mobile sources (cars, trucks, other vehicles, etc.)
Chapter 6: Biogenic sources (crops, indigenous vegetation, landscaping, etc.)
