What must establishments do to contribute to public welfare and environmental protection under the CAA?

Under the Clean Air Act (CAA), establishments have a responsibility to establish plans that include emissions limitations to effectively contribute to public welfare and environmental protection. This is essential because the CAA is designed to regulate air emissions from stationary and mobile sources to ensure that air quality standards are met, thereby safeguarding human health and the environment. By creating a detailed plan that outlines how emissions will be limited, organizations not only adhere to legal requirements but also actively participate in reducing air pollution.

Emissions limitations are crucial as they set specific targets for the amount of pollutants that can be released into the air. This structured approach helps to create accountability for facilities and drives continuous improvement in their operational practices concerning air quality. Furthermore, having these limitations established creates a framework for monitoring, reporting, and compliance, ensuring that the organizations remain aligned with governmental air quality standards.

While the other options may touch on aspects related to environmental responsibility, they do not directly capture the core requirement set forth by the CAA regarding emissions. Following federal environmental laws is typically a given for compliance, reducing costs can be a beneficial but indirect goal, and encouraging public participation, while important for transparency and accountability, does not directly impact the establishment of emission limitations. Thus, formulating a plan with emissions limitations stands out
