During a recent meeting held on February 14, 2024, Palm Beach County officials discussed significant changes proposed by the U.S. Environmental Protection Agency (EPA) regarding air emission standards for waste energy facilities. This discussion is particularly relevant as it impacts the county's Renewable Energy Facilities (REF) 1 and 2, which are crucial components of the region's waste management and energy production strategies.

The EPA's proposed revisions to the maximum achievable control technology standards aim to lower air emission limits for existing waste energy plants that combust more than 250 tons of waste per day. This change is driven by a lawsuit from environmental organizations, prompting the EPA to fulfill its obligation to review these standards every five years. The last update occurred in 2006, making the current proposal a long-overdue response to regulatory requirements.

Palm Beach County's REF 1, operational since 1989 and recognized as the cleanest waste energy plant globally, faces potential challenges under the new regulations. The facility's contract is set to expire in 2029, raising questions about the financial viability of retrofitting its air pollution control systems to comply with the stricter standards. Officials expressed concerns about the costs involved in upgrading REF 1, especially if the facility is only expected to operate for an additional five years.

A key point of contention in the proposed regulations is the elimination of exclusions for emissions during startup, shutdown, and malfunction periods. This change could lead to increased violations, particularly for carbon monoxide emissions, which are difficult to control during these phases. The current regulations allow for some flexibility, but the proposed limits could result in exceedances that have not been an issue under existing standards.

Additionally, the meeting highlighted concerns regarding continuous emissions monitoring systems. The EPA's assumption that these systems can operate without interruption is unrealistic, as they can malfunction and require maintenance. If outages are classified as violations, facilities could face frequent compliance issues, complicating their operational integrity.

In conclusion, the discussions at the Palm Beach County meeting underscore the potential implications of the EPA's proposed air emission standards on local waste energy facilities. As the comment period for the proposed regulations approaches its end on March 25, 2024, stakeholders are urged to consider the balance between environmental protection and the operational realities of waste energy management. The county's next steps will involve assessing the financial and operational impacts of these regulations while advocating for a more consultative approach in the regulatory process.
