Bernalillo County has a MSA population over 250,000 and is thus included in EPA thus included in EPA’ ’s Urban Air Toxics Strategy goals to s Urban Air Toxics Strategy goals to reduce cancer incidences by 75%, and substantially reduce reduce cancer incidences by 75%, and substantially reduce public health risks especially among highly exposed public health risks especially among highly exposed population groups. Mobile sources are targeted as well. population groups. Mobile sources are targeted as well.

• The Clean Air Act required EPA to identify a list of at least 30

The Clean Air Act required EPA to identify a list of at least 30 air toxics that pose the greatest potential health threat in air toxics that pose the greatest potential health threat in urban areas and create a list of stationary source categories urban areas and create a list of stationary source categories contributing 90% of the listed air toxics contributing 90% of the listed air toxics

• As a result, EPA identified a list of 33 air toxics of the 188

As a result, EPA identified a list of 33 air toxics of the 188 toxic air pollutants and identified 70 source categories. To toxic air pollutants and identified 70 source categories. To date, EPA has created standards for 14 of the 70 sources. date, EPA has created standards for 14 of the 70 sources.

The National Emission Standards for The National Emission Standards for Hazardous Air Pollutants Hazardous Air Pollutants

• The actual standards are codified under 40 CFR 61

The actual standards are codified under 40 CFR 61– – “ “National Emission Standards for Hazardous Air National Emission Standards for Hazardous Air Pollutants Pollutants” ” and 40 CFR 63 and 40 CFR 63 – – “ “National Emission National Emission Standards for Hazardous Air Pollutants for Source Standards for Hazardous Air Pollutants for Source Categories Categories” ”
