Additional Background Information on Connecticut Agreement</HD> The NRC published the proposed Agreement in the <E T="04">Federal Register</E> (FR) for comment once each week for four consecutive weeks on March 19, 2025 (90 FR 12795), March 26, 2025 (90 FR 13787), April 2, 2025 (90 FR 14485), and April 9, 2025 (90 FR 15259), as required by the Act. The comment period ended on April 19, 2025. The NRC received one anonymous comment submission letter from a member of the public. The commentator opposed the proposed Agreement for several reasons. No changes in the proposed Agreement or the staff's conclusions in the draft staff assessment of the State's program were made in response to the comment. The staff analysis of the comment can be found at ML25161A145. The NRC staff determined that the Connecticut Agreement State program is adequate to protect the public health and safety and compatible with the NRC's program. The Connecticut Agreement is consistent with Commission policy and thus meets the criteria for an Agreement with the Commission. After considering the request for an Agreement by the Governor of Connecticut, the supporting documentation submitted with the request for an Agreement, and its interactions with the staff of the Connecticut Department of Energy and Environmental Protection, the NRC staff completed an assessment of the Connecticut program. The agency made a copy of the staff assessment available in the NRC's PDR and electronically on the NRC's website. Based on the staff's assessment, the Commission determined on August 8, 2025, that the Connecticut program for control of radiation hazards is adequate to protect the public health and safety and compatible with the Commission's program. As of the effective date of the Agreement, a person in Connecticut possessing these materials is exempt from certain Commission regulations. The exemptions have been previously published in the FR and are codified in the Commission's regulations. The Agreement is published here as required by Section 274e. of the Act. This Agreement is a rule as defined in the Congressional Review Act (5 U.S.C. 801-808). The Office of Management and Budget has found that this action does not meet the criteria at 5 U.S.C. 804(2). The Office of Information and Regulatory Affairs has determined that this Agreement is not a significant regulatory action under Executive Order 12866. <HD SOURCE="HD1">II.
