Recent Action Recent Action

• Based on its reconsideration of the March 2008 federal

Ozone Standards, on January 7, 2010 EPA proposed new ranges of Primary and Secondary Ozone Standards.

• EPA determined the 2008 Primary Ozone Standard was

NOT protective of Public Health and the Secondary Ozone Standard was NOT protective of vegetation and forested ecosystems.

• The proposed revised standards are consistent with the

recommendations of Clean Air Scientific Advisory Committee (CASAC).

Proposed Ozone Action Proposed Ozone Action

• EPA is considering setting a Primary Ozone

Standard in the range of .060 to .070 parts per million (ppm). This is to ensure the standard is protective of public health with an adequate safety margin.

• EPA is also considering setting a new

cumulative seasonal Secondary Ozone Standard in the range of 7 to 15 ppm-hours. (ppm) to protect ecosystems.

Preliminary Unofficial Analysis Preliminary Unofficial Analysis

• If the 2010 Primary Standard is set at 0.070 ppm

– 2ZF- Double Eagle Elementary School will be at 100% of the standard @ 0.070 ppm – 2ZV - South Valley will be at 0.066 ppm, the lowest site.

• If the 2010 Secondary Standard is set at 15 ppm-hours

– 2ZF- Double Eagle Elementary School will exceed the standard @ 16.98 ppm. – 2ZV - South Valley will be at 10.17 ppm, the lowest site.

• Our Airshed would be at 100% of the proposed Primary

Ozone Standard and exceeding the upper limit of the Proposed Secondary Ozone Standard.

Upcoming Air Quality Challenges Upcoming Air Quality Challenges

• Maintaining Compliance with the Federal Ozone

Standard as they are lowered/strengthened.

• Bernalillo County is at about 93% of the Current 2008

Federal Ozone Standard.

• Ozone-Levels in Albuquerque Have Dropped in Recent

Years, but the Federal Standards for Ozone Have Been Strengthened, or Lowered, at a Faster Rate.

• Identifying, Developing and Implementing Effective

Control Strategies for Ozone precursors.

• Working together to comply with the new standards.
