Create File with EPA (and other agency) PM Guidelines

[john-waczak]

We need a file including all relevant standards for PM & other criterion pollutants which we can use for our analyses.

Here are the latest values for the National Ambient Air Quality Standards (NAAQS) as of 2024:

1. Ozone (O₃):

   • Primary and Secondary Standard: 0.070 parts per million (ppm) over an 8-hour average.

2. Particulate Matter (PM):

   • PM₂.₅ (fine particles):

     • Primary Annual Standard: 9.0 micrograms per cubic meter (µg/m³) (annual mean, averaged over 3 years).

     • 24-hour Standard: 35 µg/m³ (98th percentile, averaged over 3 years).

   • PM₁₀ (coarse particles):

     • Primary and Secondary Standard: 150 µg/m³ (24-hour average, not to be exceeded more than once per year on average over 3 years).

3. Carbon Monoxide (CO):

   • Primary Standard: 9 ppm over an 8-hour average and 35 ppm over a 1-hour average.

4. Sulfur Dioxide (SO₂):

   • Primary Standard: 75 parts per billion (ppb) over a 1-hour average.

   • Secondary Standard: 0.5 ppm over a 3-hour average.

5. Nitrogen Dioxide (NO₂):

   • Primary Standard: 53 ppb annual mean.

   • 1-hour Standard: 100 ppb (98th percentile of 1-hour daily maximum concentrations, averaged over 3 years).

6. Lead (Pb):

   • Primary and Secondary Standard: 0.15 µg/m³ (rolling 3-month average, not to be exceeded).

These standards are designed to protect public health and the environment from harmful air pollutants oai_citation:1,www.epa.gov oai_citation:2,Final Reconsideration of the National Ambient Air Quality Standards for Particulate Matter (PM) | US EPA oai_citation:3,National Ambient Air Quality Standards (NAAQS) for PM | US EPA oai_citation:4,EPA finalizes stronger standards for harmful soot pollution, significantly increasing health and clean air protections for families, workers, and communities | US EPA.
