Good Neighbor Plan for 2015 Ozone NAAQS

States Covered Under the Power Plants and Other Industries Portions of the Final Good Neighbor Plan
Power Plant Ozone Season Emissions Reductions in 2027 Relative to 2021 Under the Final Good Neighbor Plan
The estimated emissions reductions reflect the difference between the rule’s preset 2027 budgets for EGUs (this may vary based on the dynamic budget level) and adjusted current 2021 emissions for those EGUs (2021 reported emissions are adjusted to account for known or planned changes such as: retirement, planned retirement, coal-to-gas conversion, etc.). Because these estimated reductions reflect the overall change from current emissions, they are higher, on average, than the values reflected in the regulatory impact analysis (emissions reductions relative to projected future baseline emissions) and other communications materials.
Industrial Source Ozone Season Emissions Reductions in 2026 Relative to 2019 Under the Final Good Neighbor Plan
The estimated percent reductions are calculated using total 2019 non-EGU emissions, including non-EGU point source emissions, oil and gas point source emissions, and the MWC portion of EGU emissions.Interstate Pollution Linkages Under the Good Neighbor Plan

January 31, 2023 – Final Disapproval of 2015 Good Neighbor SIP Submissions
To protect air quality in communities affected by harmful ground-level ozone (or “smog”) pollution, EPA finds that certain states failed to meet their obligations under the Clean Air Act to protect communities in other states from unhealthy levels of ozone pollution. EPA has disapproved 19 state implementation plan (SIP) submissions and partially approved and partially disapproved 2 SIP submissions addressing the good neighbor provision for the 2015 ozone NAAQS.
August 19, 2022 - Good Neighbor Plan Allowance Recordation Rule
The Environmental Protection Agency is taking final action to revise certain administrative deadlines under seven allowance trading programs for nitrogen oxides and sulfur dioxide, including all Cross-State Air Pollution Rule (CSAPR) trading programs and the Texas SO2 Trading Program. EPA proposed to revise these deadlines as part of the proposed Good Neighbor Plan published April 2022.
