Understanding Prevention of Significant Deterioration (PSD) in Environmental Law
Definition & Meaning
The Prevention of Significant Deterioration (PSD) is a program established by the Environmental Protection Agency (EPA) aimed at maintaining air quality in areas where it currently meets or exceeds national standards. This program requires state or federal permits for new or modified industrial sources to limit their emissions of air pollutants. The PSD program is designed to ensure that air quality remains healthy and that any new developments do not degrade the existing air quality.

Legal Use & context
The PSD program is primarily used in environmental law and regulatory compliance. It is relevant for industries that are planning to construct or modify facilities that may emit air pollutants. Businesses must navigate the permitting process to ensure compliance with the PSD requirements. Users can manage some aspects of this process themselves by utilizing legal templates from US Legal Forms, which can provide guidance on the necessary documentation and procedures.
Key legal elements
Real-world examples
Here are a couple of examples of abatement:
Example 1: A manufacturing company plans to expand its facility and install new machinery that will increase emissions. Before proceeding, the company must apply for a PSD permit to evaluate the potential impact on local air quality.
Example 2: A power plant intends to upgrade its operations to improve efficiency. It must undergo the PSD permitting process to ensure that the upgrades do not result in significant deterioration of air quality. (hypothetical example)
Relevant laws & statutes
Key statutes related to the PSD program include:
The Clean Air Act (CAA), which establishes the framework for regulating air emissions.
EPA regulations found in Title 40 of the Code of Federal Regulations (CFR), particularly Part 52, which details the PSD requirements.
