Question

Quizplus · Accepted Answer

The NAAQS (National Ambient Air Quality Standards) represent a set of standards for certain pollutants that have two levels: primary (which protects public health) and secondary (which protects public welfare, such as crops and buildings). The pollutants covered by the NAAQS are divided into six groups, not five, and the standards apply to both stationary and mobile sources of pollution. The NAAQS are administered by the EPA (Environmental Protection Agency), which is a federal agency, but state and local governments also have responsibilities for implementing and enforcing the standards.
