Understanding and Implementing the New West Pinal County, AZ Fugitive Dust Rule

Updated: Mar 27, 2023

Air quality is a critical aspect of maintaining a healthy environment for both the ecosystem and the residents of any region. The Pinal County Air Quality Control District (PCAQCD) in Arizona has recently drafted a new rule aimed at controlling fugitive dust emissions to protect the air quality and the well-being of its inhabitants. The draft rule, which can be accessed here, introduces a set of Best Available Control Measures (BACM) and Most Stringent Measures (MSM) to curb the emission of dust particles from various sources. In this blog post, we will discuss the key aspects of the new rule and how it affects different sectors of the community.




Overview of the Rule


The new rule, titled "West Pinal County BACM/MSM General Fugitive Dust," focuses on reducing particulate matter (PM-10) emissions, which consist of particles with a diameter of 10 micrometers or smaller. These particles pose a significant health risk to the public, as they can easily be inhaled and cause respiratory issues. The rule applies to a wide range of activities, such as construction sites, unpaved parking lots, and agricultural operations.


Key Aspects of the Rule


Construction and Demolition Activities

The rule mandates that construction and demolition sites must implement control measures to reduce dust emissions. Some of these measures include:
  • Applying water or chemical stabilizers to control dust.

  • Using wind barriers or windbreaks to prevent the spread of dust.

  • Limiting the speed of vehicles on unpaved surfaces to 15 miles per hour.

  • Ensuring proper maintenance of roads and equipment to minimize dust emissions.

Unpaved Roads and Parking Lots


Owners and operators of unpaved roads and parking lots must implement dust control measures to minimize emissions. These measures may include:

  • Applying gravel or other suitable materials to reduce dust generation.

  • Using water or chemical stabilizers to control dust.

  • Establishing a regular schedule for maintaining the road or parking lot surface.

Agricultural Operations

Farmers and ranchers are required to adopt dust control measures to reduce emissions from their agricultural operations. Some of the recommended practices include:

  • Implementing conservation tillage practices to minimize soil disturbance.

  • Using cover crops or mulching to protect the soil from wind erosion.

  • Applying water or other dust suppressants during land preparation and harvesting activities.

Enforcement and Penalties

The PCAQCD is responsible for enforcing the rule and ensuring compliance with its provisions. Failure to comply with the rule can result in penalties, which may include fines, orders to cease operations, and other legal actions.


Conclusion


The West Pinal County BACM/MSM General Fugitive Dust rule is an essential step towards improving air quality and protecting the health of the residents and the environment. By implementing the best practices and stringent measures outlined in the rule, businesses and individuals can contribute to a cleaner, healthier future for the region.
