On August 11, the National Resource Defense Council announced that more than 2,000 “Code Orange” alerts, which mean air is unhealthy for “people with lung disease, older adults, and children were issued this year in around 250 communities nationwide. The environmental group used the same air quality index as EPA, which includes green, yellow, orange, red, purple, and maroon designations for air quality. NRDC argues that this is further proof that EPA should rush to finalize ozone standards.
