(a) You need a deviation approved under 501.4 to omit any required provision or clause.
(b) You also need an approved deviation to modify the language of a provision or clause mandated by statute (e.g., GSAR 552.203-5, Covenant Against Contingent Fees, FAR 52.215-2, Audit and Records-Negotiation). The authorizing statute must allow for a waiver.
(c) Certain clauses required by non-GSA regulations require approval of the issuing agency before you can delete or modify them. For example, 52.222-26, Equal Opportunity; 52.222-35, Affirmative Action for Disabled Veterans and Veterans of the Vietnam Era; and 52.222-36, Affirmative Action for Workers with Disabilities, require the approval of the Department of Labor’s Office of Federal Contract Compliance Programs before they can be deleted from or modified in the SFO or lease.
