What is an Attainment Area? A Guide to Air Quality Standards

Definition & Meaning

An attainment area is a geographic region that meets or exceeds the air quality standards set by the National Ambient Air Quality Standards (NAAQS) under the Clean Air Act (CAA). This means that the air quality in these areas is considered satisfactory for certain pollutants. It is important to note that an area can be classified as an attainment area for one type of pollutant while being designated as a nonattainment area for others, indicating varying levels of air quality across different pollutants.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A city that has successfully reduced its ozone levels through regulatory measures may be classified as an attainment area for ozone, while still being a nonattainment area for particulate matter due to higher levels of dust and smoke.

Example 2: A rural region may be designated as an attainment area for carbon monoxide but classified as nonattainment for sulfur dioxide due to emissions from nearby industrial activities. (hypothetical example)

State-by-state differences

State Attainment Areas Nonattainment Areas
California Some urban areas are attainment for certain pollutants. Many areas are nonattainment for ozone and particulate matter.
Texas Several regions are attainment for carbon monoxide. Houston is a nonattainment area for ozone.
New York New York City is an attainment area for most pollutants. Some upstate areas are nonattainment for particulate matter.

This is not a complete list. State laws vary and users should consult local rules for specific guidance.
