 and SO2 control technologies for Independence, Nelson 6, NISCO, and Ninemile.  Responses to the information collection requests were submitted to the respective state agencies.  Louisiana issued its draft SIP which did not propose any additional air emissions controls for the affected Entergy units in Louisiana.  Some public commenters, however, believe additional air controls are cost-effective.  In August 2024, Louisiana issued a revised SIP proposal for public comment.  The revised proposed SIP would not require any additional pollution control installations on any Entergy-owned units in Louisiana.  Comments on the revised SIP were due in September 2024 and the Louisiana Department of Environmental Quality (LDEQ) is currently reviewing comments received on the revised proposal.  The agency, like many other state agencies, did not meet the July 31, 2021 deadline to submit a SIP to the EPA for review.

Similar to the LDEQ, the Arkansas Department of Energy and Environment, Division of Environmental Quality (ADEQ) did not meet the July 31, 2021 SIP submission deadline, but subsequently submitted a final SIP to the EPA for review.  The ADEQ reviewed Entergy’s Independence plant but determined that additional air emission controls would not be cost-effective considering the facility’s commitment to cease coal-fired combustion by December 31, 2030.

The Texas Commission on Environmental Quality has completed its second-planning period SIP and submitted it to the EPA for review.  There were no Entergy sources selected for additional emission controls.  In June 2024, the EPA entered into a consent decree that sets deadlines for the EPA to take final action on 34 states’ SIP submittals.  This includes Arkansas and Texas, which are due August 2026 and May 2025, respectively.

The Mississippi Department of Environmental Quality also did not meet the July 31, 2021 SIP submission deadline.   In June 2023 Mississippi issued its proposed SIP for public notice and comment but did not propose additional pollution controls for Entergy sources.

In August 2022 the EPA issued findings of failure to submit regional haze SIPs to 15 states, including Louisiana and Mississippi.  These findings were effective September 2022, which started the two-year period for the EPA to either approve a SIP submitted by the state or issue a final federal plan.  That two-year period expired in September 2024, but
