Proposed rule.

Summary

The Environmental Protection Agency (EPA) is proposing to formally accept a plan that the Maricopa County Air Quality Department (MCAQD) submitted to control gases released from existing municipal solid‑waste landfills in Arizona. The plan sets limits and monitoring requirements for landfill gas—such as methane and other pollutants—to help keep air quality in line with the Clean Air Act’s standards for public health and the environment. The rule is issued by the EPA and applies to the state of Arizona, specifically to the owners and operators of municipal solid‑waste landfills within Maricopa County. By approving the county’s plan, the EPA would recognize it as meeting federal expectations, allowing the county to enforce the outlined controls instead of the agency imposing its own nationwide requirements. The proposal was published on November 5, 2026, and the public may submit comments until December 7, 2026. After the comment period closes, the EPA will review the feedback and decide whether to finalize the approval. If approved, the county’s landfill‑gas controls will become the enforceable standards for the affected facilities.
