The regulations governing checks drawn on the United States and on designated depositories of the United States do not apply to fiscal agency checks, unless a statute specifically provides differently, or unless we state differently in this part. If a definition or matter pertaining to fiscal agency checks is not specifically covered in this part, we will apply the provisions of Regulations J of the Board of Governors of the Federal Reserve System, at 12 CFR part 210 . To the extent not otherwise covered by this part or by Regulation J, we will apply the provisions of the Uniform Commercial Code (U.C.C.)
