The Maricopa County Air Quality Department's (MCAQD) Emissions Inventory (EI) Section collects, reviews, stores and manages stationary source air pollution emissions data for sources in Maricopa County. The EI Section also collects emission fees from Title V sources and provides data to county, state and federal agencies.
A point source emissions inventory shows annual air pollutant emissions for one specific business location. An emissions inventory may be requested by MCAQD of any facility with an air quality permit in Maricopa County. In January 2009, the EI Section distributed reporting forms and instructions to those businesses that were requested to submit an emissions report for calendar year 2008.
Annual emissions inventories serve a number of purposes:
-
They help determine a source's compliance with its air quality permit conditions as well as Maricopa County rules and regulations.
-
They help identify pollutant sources that may need new or additional controls, and thus provide a basis for improved air pollution control strategies.
-
They also provide a means of assessing progress in achieving reductions from existing controls.
-
They provide the basis for determining annual emission fees from Title V sources.
-
Inventory data are used as input for air quality modeling to demonstrate attainment of national ambient air quality standards (NAAQS).
