Proposed EPA Rule Leads to Quadrupling Group 3 Ozone Season CSAPR NOx Prices | Emissions Watch Blog

Published June 7, 2022 | Tom Bausemer | Blog Postemissions-watch

The EPA issued a proposed rule in February 2022 that, if finalized, will implement significant programmatic changes, and establish lower emissions limits to the existing Group 3 Ozone Season Cross-State Air Pollution Rule (CSAPR) beginning in the 2023 ozone season. Following the issuance of this proposed rule, Group 3 CSAPR NOx allowance prices have quadrupled from approximately $6,500/ton in February to $28,500/ton (June 6).

The table below highlights the most significant proposed changes to the rule, many of which are driving this recent increase in allowance prices.
