48 C.F.R. § 3401.303
(a) The EDAR is issued as chapter 34 of title 48 of the CFR.
(3) Supplementary material for which there is no counterpart in the FAR will be codified with a suffix beginning with “70” or, in cases of successive sections and subsections, will be numbered in the 70 series (i.e., 71-79). These supplementing sections and subsections will appear to the closest corresponding FAR citation; e.g., FAR subpart 16.4 may be augmented in the EDAR by citing EDAR 3416.470 and FAR 16.403 may be augmented in the EDAR by citing EDAR 3416.403-70. (Note: These citations are for illustrative purposes only and may not actually appear in the published EDAR). For example:
| FAR | Is implemented as | Is augmented as |
|---|---|---|
| 15 | 3415 | 3415.70 |
| 15.1 | 3415.1 | 3415.170 |
| 15.101 | 3415.101 | 3415.101-70 |
| 15.101-1 | 3415.101-1 | 3415.101-170 |
