The Environmental Protection Agency (EPA) has made available a collection of applicability determinations, alternative monitoring decisions, and regulatory interpretations related to various air quality standards and programs, such as NSPS, NESHAP, and others. These determinations help clarify whether specific facilities or equipment must follow certain EPA regulations, and they often involve evaluating requests for alternative monitoring methods or exemptions. A summary of 59 documents added to the Applicability Determination Index on October 22, 2020, includes topics like monitoring plans for emissions from industrial processes and compliance with air quality standards for specific facilities. These documents are available online for public access, and complete details can be found through the EPA's Clean Air Act Compliance Monitoring website.
Simple Explanation
The EPA has shared decisions on rules for air pollution from factories and other sources, showing which rules apply to them and if any special exceptions are allowed. These decisions are helpful for understanding how to keep the air clean, even though the details can be tricky to understand.
