23 CFR 710.305 - Environmental analysis.
The National Environmental Policy Act (NEPA) process, as described in FHWA's NEPA regulations in 23 CFR part 771, normally must be conducted and concluded with a record of decision (ROD) or equivalent before Federal funds can be placed under agreement for acquisition of right-of-way. Where applicable, a State also must complete Clean Air Act (42 U.S.C. 7401 et seq.) project level conformity analysis. In areas in which the Clean Air Act conformity determination has lapsed, acquiring agencies must coordinate with Federal Highway Administration for special instructions prior to initiating new projects or continuing activity on existing projects. At the time of processing an environmental document, a State may request reimbursement of costs incurred for early acquisition, provided conditions prescribed in 23 U.S.C. 108(c) and 23 23 CFR 710.501, are satisfied.
