Question

Quizplus · Accepted Answer

The operations of Commercial Concrete, Inc., are major sources of air pollution, which means they need to use the maximum achievable control technology (MACT) to minimize their emissions. MACT is the technology-based regulatory approach that enforces the largest achievable emission reductions using control technologies that are already in use in practice. It is the most stringent control strategy required by the Clean Air Act (CAA) and is designed to reduce pollution to the level that is achievable without significantly impeding economic growth or imposing undue costs. A and B are not sufficient to provide the required level of control, and D emphasizes affordability over effectiveness.
