Section 35.151(b)(3) Alterations to historic facilities

The final rule renumbers the requirements for alterations to historic facilities enumerated in current Sec. 35.151(d)(1) and (2) as Sec. 35.151(b)(3)(i) and (ii). Currently, the regulation provides that alterations to historic facilities shall comply to the maximum extent feasible with section 4.1.7 of UFAS or section 4.1.7 of the 1991 Standards. See 28 CFR 35.151(d)(1). Section 35.151(b)(3)(i) of the final rule eliminates the option of using UFAS for alterations that commence on or after March 15, 2012. The substantive requirement in current Sec. 35.151(d)(2)--that alternative methods of access shall be provided pursuant to the requirements of Sec. 35.150 if it is not feasible to provide physical access to an historic property in a manner that will not threaten or destroy the historic significance of the building or facility--is contained in Sec. 35.151(b)(3)(ii).
