Five rulemakings are being proposed by the Maricopa County Air Quality Department (MCAQD) for the calendar year 2015 to address the requirements of the State Implementation Plan (SIP) for “moderate” nonattainment for the 2008 eight-hour ozone National Ambient Air Quality Standards (NAAQS) according to a June 25, 2015 Trinity Consultants report.

Three of the rulemakings are being proposed to address Reasonably Available Control Technology (RACT) for nitrogen oxides (NOx) which are precursors to ozone.

• Rule 322 (Power Plant Operations) limits the discharge of NOx, sulfur oxides, particulate matter, and carbon monoxide emissions into the atmosphere from stationary fossil-fuel-fired equipment at existing power plants and existing cogeneration plants.
• Rule 323 (Fuel Burning Equipment From Industrial I Commercial I Institutional (ICI) Sources) limits the discharge of NOx, sulfur oxides, particulate matter, and carbon monoxide emissions into the atmosphere from fuel burning combustion equipment at industrial, commercial, and institutional (ICI) sources.
• Rule 324 (Stationary Internal Combustion (IC) Engines) limits the discharge of carbon monoxide, NOx, sulfur oxides, VOCs, and particulate matter emissions from stationary internal combustion (IC) engines.

What this means to you
Maricopa County (Phoenix, AZ) is proposing rules for calendar year 2015 to address state plan requirements for moderate non-attainment of the eight-hour ozone national ambient air quality standard (NAAQS) for ozone. Rule 324 targets stationary IC engines for NOx, sulfur oxides, VOC’s and particulate matter.
