to 5 U.S.C. 552a(k)(6): 5 U.S.C. 

552a(c)(3), 5 U.S.C. 552a(d)(1), (2), (3), 

and (4), 5 U.S.C. 552a(e)(1), 5 U.S.C.

552a(f). 

(n) Reasons for exemptions under 5 

U.S.C. 552a(k)(6). The reason for 

exempting the system of records is that 

disclosure of the material in the system 

would compromise the objectivity or 

fairness of the examination process. 

(o) Exempt information included in 

another system. Any information from a 

system of records for which an 

exemption is claimed under 5 U.S.C. 

552a(j) or (k) which is also included in 

another system of records retains the 

same exempt status such information 

has in the system for which such 

exemption is claimed.

amending Mailing Standards of the

SUPPLEMENTARY INFORMATION: On 

November 6, 2023, the Postal Service 

published a notice of proposed 

rulemaking (88 FR 76162–76163) to 

further amend subsections 602.1.5.4 and 

609.4.3 to clarify the procedures 

applicable to undeliverable domestic 

mailpieces bearing a foreign return 

address. The Postal Service did not 

receive any formal comments. 

The Postal Service is revising DMM 

subsections 602.1.5.4, and 609.4.3, to 

clarify that undeliverable domestic 

mailpieces with a foreign return address 

will be handled in accordance with the 

Postal Service’s dead mail procedures. 

In a separate rule, the Postal Service 

will also revise a few related sections of 

the International Mail Manual (IMM) 

including subsection 762.2, 

Undeliverable Domestic Mail Bearing 

U.S. Postage and a Foreign Return 

Address. 

We believe these revisions will 

provide customers with a more efficient 

mailing experience. The Postal Service 

adopts the described changes to Mailing 

Standards of the United States Postal 

Service, Domestic Mail Manual (DMM), 

incorporated by reference in the Code of 

Federal Regulations. 

We will publish an appropriate 

amendment to 39 CFR part 111 to reflect 

these changes.

AGENCY: Environmental Protection

ACTION: Interim final rule and request 

for comments. 

SUMMARY: The U.S. Environmental 

Protection Agency is amending a 

provision of the recently finalized 

Technology Transitions Program under 

the American Innovation and 

Manufacturing Act (AIM Act). This 

action allows one additional year, until 

January 1, 2026, solely for the 

installation of new residential and light 

commercial air conditioning and heat 

pump systems using components 

manufactured or imported prior to 

January 1, 2025. The existing January 1, 

2025, compliance date for the 

installation of certain residential and 

light commercial air conditioning and 

heat pump systems may result in 

significant stranded inventory that was 

intended for new residential 

construction. EPA is promulgating this 

action to mitigate the potential for 

significant stranded inventory in this 

subsector. In addition, EPA is clarifying
