EPA Proposal May Limit Public Engagement in Air Permit Processes

Concerns Rise Over EPA's Proposed Changes to Air Permit Procedures

The Environmental Protection Agency (EPA) has initiated a proposal that could significantly change how public input is managed in the processing of air permits, especially those pertaining to "minor sources." This move has prompted criticism from environmental groups focused on potential implications for community involvement and oversight.

At the core of the proposal is the intent to eliminate the federally mandated 30-day public notice period for minor source air permits, which are essential for various operations, including those utilized by data centers for backup diesel generators and small gas turbines. The new framework would leave it up to state and local air agencies to decide how much public commentary would be solicited.

Sandy Bahr, director of the Sierra Club's Grand Canyon Chapter, expressed her concerns, stating that the changes seem to favor the data center industry at the cost of public involvement. Bahr commented, “The trend by the government is to, in the name of efficiency, cut the public out. It is a disturbing trend because it means less transparency, less opportunity to raise issues that can be addressed early in the process.”

She pointed out a particular challenge for Arizona, where state law does not allow local agencies to impose stricter air quality regulations than those set by the EPA. “So when the EPA weakens something, as they are with minor source permitting, the Arizona Department of Environmental Quality has no choice but to follow the EPA,” Bahr further explained.

In response to the proposal, the Arizona Department of Environmental Quality (ADEQ) indicated that it is currently reviewing the implications of the EPA's changes. ADEQ assured that their existing processes for minor source permits, which offer considerable opportunities for public notification and commentary, remain intact. They stated, “We will carefully review the federal proposal during the comment period to ensure we continue serving the best interest of Arizona communities.”
