To amend the Endangered Species Act of 1973 to expand the exemption process under section 7 of that Act with respect to national security and significant adverse national or regional economic impacts.

H.R. 3845 would broaden how the Endangered Species Act (ESA) Section 7 exemption process operates when a federal action needed for national security or for significant adverse national or regional economic impacts might otherwise jeopardize listed species or habitat. The bill creates a pathway for exemptions when a modification or a reasonable and prudent alternative (RPA) necessary to comply with Section 7 would impair national security or cause significant economic harm. It expands interagency involvement by requiring consultation with the National Security Council and the Director of the National Economic Council, and it adds new reporting requirements to accompany any exemption request. The Secretary would review an exemption application first, and a dedicated committee would issue a final determination after the required interagency report is completed. The bill also tightens certain procedural and informational requirements that must accompany an exemption application, including assessments of whether irreversible commitments to resources would be made and how the proposed action would interact with national security and economic considerations. In short, the bill elevates the role of national security and economic-impact considerations in ESA Section 7 exemptions, mandating interagency input and structured reporting before a final exemption decision can be issued.
