§ 115-1.109 Numbering in FPMR system.
(a) The numbering system used in EPPMR conforms to that of the FPMR except for the chapter number. The first three digits represent the Chapter number assigned to this Agency in title 41, Code of Federal Regulations (CFR). In FPMR the chapter number is 101 and in EPPMR the Chapter number is 115.
(b) Where EPA Chapter 115 implements Chapter 101 the material will be numbered and captioned to correspond to the FPMR part, subpart, section or subsection, e.g., 115-1.106 “Applicability of FPMR” implements 101-1.106 of FPMR.
(c) Where Chapter 115 supplements the FPMR and deals with subject matter not contained in the FPMR, the EPPMR material is numbered to follow that which is most closely related to similar material in the FPMR, Supplementing material is numbered “50” or higher.
