Exploring Ozone Precursor Control Measures in the Phoenix Area

In a recent report commissioned by the Maricopa Association of Governments (MAG), Ramboll, an international engineering and consulting firm, analyzed ozone precursor control measures in the Phoenix Ozone Nonattainment Area. Below is a summary of Ramboll's report and a discussion of its implications for air quality management in the Phoenix area.



The Ramboll report, titled "Ozone Precursor Control Measures for the Maricopa County Nonattainment Area," aims to identify and evaluate potential control measures for ozone precursors – volatile organic compounds (VOCs) and nitrogen oxides (NOx). The report focuses on the Maricopa County nonattainment area, which has consistently struggled to meet federal ozone standards.


Key Findings


Ramboll's analysis identified 26 potential control measures that could help reduce ozone precursor emissions in the Maricopa County nonattainment area. These measures were grouped into five categories:

  1. Stationary Sources: Targeting emissions from industrial facilities, oil and gas production, and commercial businesses.

  2. Area Sources: Focusing on smaller sources, such as consumer products, architectural coatings, and residential fuel combustion.

  3. On-Road Mobile Sources: Addressing emissions from vehicles, including cars, trucks, and buses.

  4. Off-Road Mobile Sources: Targeting emissions from construction equipment, recreational vehicles, and other off-road sources.

  5. Transportation Control Measures (TCMs): Promoting alternatives to single-occupancy vehicle trips, including public transportation and carpooling.

The report also analyzed the cost-effectiveness of each control measure, enabling policymakers to make informed decisions about resource allocation.


Implications for Air Quality Management


The Ramboll report offers valuable insights into air quality management in Maricopa County. By identifying the most effective and cost-efficient control measures, local governments and businesses can target their efforts toward reducing ozone precursor emissions and ultimately improving air quality in the region.


For businesses operating in Maricopa County, understanding these control measures and staying ahead of potential regulatory changes is crucial. Tipple Consulting can help businesses navigate the ever-evolving landscape of air quality regulations and develop strategies to minimize emissions, comply with regulations, and reduce overall environmental impact.
