To amend the Coastal Zone Management Act of 1972 to establish a conclusive presumption that a State concurs to certain activities, and for other purposes.

HR 1874 amends the Coastal Zone Management Act to create a "conclusive presumption" that coastal states automatically approve certain federal projects in their coastal zones. This applies to national security activities, critical infrastructure projects (like energy or transportation systems), disaster recovery efforts, and projects in areas with high unemployment or low income. States can no longer delay these projects through objections, though the federal Secretary of Commerce may override the presumption within 30 days if the project doesn’t qualify. The bill streamlines approvals for these specific activities while maintaining federal oversight.
