Title 23 › Chapter 1— FEDERAL-AID HIGHWAYS › § 169
A State or metropolitan planning organization can create one or more programmatic mitigation plans during statewide or metro transportation planning to deal with possible environmental impacts from future transportation projects. The plans can be regional, ecosystem, watershed, or statewide. They can cover many kinds of resources or focus on one (like waterways, parks, or wildlife). A plan can apply to all projects in an area or to one type of project. The State or MPO sets the plan’s scope after talking with the agencies that manage the affected resources. A plan can include an assessment of resource condition and threats; ideas for improving resources through strategic mitigation; standard ways to reduce certain impacts; rules for choosing mitigation (for example ratios or site criteria); monitoring and adjusting measures over time; and a note of any legal requirements. Before adopting a plan, the State or MPO must consult the resource agencies, publish a draft for agency and public review, consider comments, and address them in the final plan. Plans can be combined with other plans (watershed, ecosystem, species recovery, growth management, or land use). Federal agencies doing environmental reviews, permits, or approvals must give substantial weight to the plan’s recommendations when acting under the National Environmental Policy Act of 1969 or other federal environmental laws, and the law does not limit using programmatic approaches under NEPA.
