Municipal solid waste incinerators must meet emissions limits from the EPA's January 2024 proposed amendments to new source performance standards for large municipal waste combustion units, with carbon monoxide limits enforced hourly during operation.

Incinerator owners must submit plans to deploy continuous emissions monitoring or automated sampling systems for 21 air contaminants including carbon dioxide, dioxin/furan, mercury, PFAS, lead, and particulate matter.

Facilities must implement automated, transparent data-sharing systems that report emissions in concentrations and pounds per day/year, compare against limits, list violations, and automatically notify regulators and the public of exceedances.

Existing resource recovery facilities subject to renewable energy standards are capped at processing no more than 274,000 tons of mixed municipal solid waste annually beginning in 2026.

The commissioner must adopt implementing rules, and within one year of data-sharing implementation, must determine whether monitoring data is sufficiently accurate for enforcement purposes.
