EPA Approves Wisconsin's Plan to Improve Air Quality in Three Areas
Official: Air Plan Approval; Wisconsin; Moderate Attainment Plan Elements for Wisconsin's 2015 Ozone Standard Areas
Reading: The EPA is approving Wisconsin's existing State Implementation Plan framework with motor vehicle budgets and inspection programs—extending and formalizing the state's existing attainment strategy rather than strengthening standards or creating new protections.
This approval means Wisconsin can move forward with implementing these strategies to bring air quality into compliance with federal requirements.
In clear language
The EPA has approved Wisconsin's air quality improvement plan for three regions (parts of Chicago, Milwaukee, and Sheboygan areas) that currently do not meet federal ozone standards. The plan includes measures to reduce emissions from cars and trucks, vehicle inspection programs, and rules for new industrial sources. This approval means Wisconsin can move forward with implementing these strategies to bring air quality into compliance with federal requirements.
