31 CFR § 370.0 - What does this part cover?
(a) Scope. This part applies to the transfer of funds by the Automated Clearing House method as used by us in connection with United States securities. This part also provides regulations for the electronic submission of transaction requests through us, except as varied by agreement or as otherwise provided. This part does not apply to transactions for the sale of United States Savings Bonds accomplished through savings bond issuing agents generally, except and to the extent we direct otherwise.
(b) Operating Rules of the National Automated Clearing House Association and Regulations of the Financial Management Service. The Operating Rules of the National Automated Clearing House Association generally apply to these transactions. However, the Operating Rules do not apply to the extent that the Operating Rules are preempted entirely and excluded specifically by application of Financial Management Service regulations in part 210 of this chapter. In the event of any inconsistencies between this part 370 and either the Operating Rules or part 210, this part 370 applies.
(c) Regulations of the Board of Governors of the Federal Reserve. To the extent that Regulation E (12 CFR part 205) and Regulation Z (12 CFR part 226) of the Board of Governors of the Federal Reserve System apply to transactions authorized by this part, those Federal laws are unaffected by this part 370.
(d) Variance by agreement. The terms of this part may be varied by agreement.
