DEPARTMENT OF THE TREASURY 

31 CFR Part 1 

RIN 1505–AC80 

Privacy Act Regulations; Correction 

AGENCY: Department of the Treasury. 

ACTION: Final rule; correcting 

amendment. 

SUMMARY: The Department of the 

Treasury is correcting a final rule that 

appeared in the Federal Register on 

October 20, 2022. The final rule 

modified the master list of System of 

Records Notices (SORN) in the Privacy 

Act Regulations. Several revisions that 

were inadvertently omitted from the 

table are corrected in this document. 

DATES: Effective December 26, 2023. 

FOR FURTHER INFORMATION CONTACT: 

Ryan Law, Deputy Assistant Secretary 

for Privacy, Transparency, and Records 

telephone: (202) 622–5710. 

SUPPLEMENTARY INFORMATION: The 

Department of the Treasury is correcting 

a final rule published in the Federal 

Register on October 20, 2022, at 87 FR 

63904. The Department has recently 

discovered that certain information was 

inadvertently omitted from the final 

rule.

List of Subjects in 31 CFR Part 1 

Privacy. 

Accordingly, the Department of the 

Treasury amends 31 CFR part 1 by 

making the following correcting 

amendment: 

PART 1—DISCLOSURE OF RECORDS 

■ 1. The authority citation for part 1 

continues to read as follows: 

Authority: 5 U.S.C. 301, 552, 552a, 553; 

31 U.S.C. 301, 321; 31 U.S.C. 3717. 

■ 2. Revise § 1.36 to read as follows: 

§ 1.36 Systems exempt in whole or in part 

from provisions of the Privacy Act and this 

part. 

(a) In general. In accordance with 5 

U.S.C. 552a(j) and (k) and § 1.23(c), 

Treasury hereby exempts the systems of 

records identified in paragraphs (c) 

through (o) of this section from the 

following provisions of the Privacy Act 

for the reasons indicated. 

(b) Authority. The rules in this section 

are promulgated pursuant to the 

authority vested in the Secretary of the 

Treasury by 5 U.S.C. 552a(j) and (k) and 

pursuant to the authority of § 1.23(c). 

(c) General exemptions under 5 U.S.C. 

552a(j)(2). (1) Under 5 U.S.C. 552a(j)(2), 

the head of any agency may promulgate 

rules to exempt any system of records 

within the agency from certain 

provisions of the Privacy Act if the 

agency or component thereof that 

maintains the system performs as its 

principal function any activities 

pertaining to the enforcement of 

criminal laws. Certain Treasury 

components have as their principal 

function activities pertaining to the 

enforcement of criminal laws. This 

paragraph (c) applies to the following 

systems of records maintained by 

Treasury: 

(i) Treasury-wide.

(2) The Department hereby exempts 

the systems of records listed in 

paragraphs (c)(1)(i) through (vi) of this 

section from the following provisions of 

the Privacy Act, pursuant to 5 U.S.C. 

552a(j)(2): 5 U.S.C. 552a(c)(3) and (4), 5 

U.S.C. 552a(d)(1), (2), (3), (4), 5 U.S.C. 

552a(e)(1), (2) and (3), 5 U.S.C. 

552a(e)(4)(G), (H), and (I), 5 U.S.C. 

552a(e)(5) and (8), 5 U.S.C. 552a(f), and 

5 U.S.C. 552a(g). 

(d) Reasons for exemptions under 5 

U.S.C. 552a(j)(2). (1) 5 U.S.C. 

552a(e)(4)(G) and (f)(l) enable 

individuals to inquire whether a system 

of records contains records pertaining to 

them. Application of these provisions to 

the systems of records would give 

individuals an opportunity to learn 

whether they have been identified as 

suspects or subjects of investigation. As 

further described in the paragraphs 

(d)(2) through (12) of this section, access 

to such knowledge would impair the 

Department’s ability to carry out its 

mission, since individuals could: 

(i) Take steps to avoid detection; 

(ii) Inform associates that an 

investigation is in progress; 

(iii) Learn the nature of the 

investigation; 

(iv) Learn whether they are only 

suspects or identified as law violators; 

(v) Begin, continue, or resume illegal 

conduct upon learning that they are not 

identified in the system of records; or 

(vi) Destroy evidence needed to prove 

the violation. 

(2) 5 U.S.C. 552a(d)(1), (e)(4)(H) and 

(f)(2), (3) and (5) grant individuals 

access to records pertaining to them. 

The application of these provisions to 

the systems of records would 

compromise the Department’s ability to 

provide useful tactical and strategic 

information to law enforcement 

agencies. 

(i) Permitting access to records 

contained in the systems of records 

would provide individuals with 

information concerning the nature of 

any current investigations and would 

enable them to avoid detection or 

apprehension by: 

(A) Discovering the facts that would 

form the basis for their arrest; 

(B) Enabling them to destroy or alter 

evidence of criminal conduct that 

would form the basis for their arrest; 

and 

(C) Using knowledge that criminal 

investigators had reason to believe that 

a crime was about to be committed, to 

delay the commission of the crime or 

commit it at a location that might not be 

under surveillance. 

(ii) Permitting access to either ongoing or closed investigative files would 

also reveal investigative techniques and 

procedures, the knowledge of which 

could enable individuals planning 

crimes to structure their operations to 

avoid detection or apprehension. 

(iii) Permitting access to investigative 

files and records could, moreover, 

disclose the identity of confidential 

sources and informants and the nature 

of the information supplied and thereby 

endanger the physical safety of those 

sources by exposing them to possible 

reprisals for having provided the 

information. Confidential sources and 

informants might refuse to provide 

criminal investigators with valuable 

information unless they believe that 

their identities will not be revealed 

through disclosure of their names or the 

nature of the information they supplied. 

Loss of access to such sources would 

seriously impair the Department’s 

ability to carry out its mandate. 

(iv) Furthermore, providing access to 

records contained in the systems of 

records could reveal the identities of 

undercover law enforcement officers 

who compiled information regarding the 

individual’s criminal activities and 

thereby endanger the physical safety of 

those undercover officers or their 

families by exposing them to possible 

reprisals. 

(v) By compromising the law 

enforcement value of the systems of 

records for the reasons outlined in 

paragraphs (d)(2)(i) through (iv) of this 

section, permitting access in keeping 

with these provisions would discourage 

other law enforcement and regulatory 

agencies, foreign and domestic, from 

freely sharing information with the 

Department and thus would restrict the 

Department’s access to information 

necessary to accomplish its mission 

most effectively. 

(vi) Finally, the dissemination of 

certain information that the Department 

maintains in the systems of records is 

restricted by law. 

(3) 5 U.S.C. 552a(d)(2), (3) and (4), 

(e)(4)(H), and (f)(4) permit an individual 

to request amendment of a record 

pertaining to him or her and require the 

agency either to amend the record, or to 

note the disputed portion of the record 

and to provide a copy of the 

individual’s statement of disagreement 

with the agency’s refusal to amend a 

record to persons or other agencies to 

whom the record is thereafter disclosed. 

Since these provisions depend on the 

individual having access to his or her 

records, and since these rules exempt 

the systems of records from the 

provisions of the Privacy Act relating to 

access to records, for the reasons set out 

in paragraph (d)(2) of this section, these 

provisions should not apply to the 

systems of records. 

(4) 5 U.S.C. 552a(c)(3) requires an 

agency to make accountings of 

disclosures of a record available to the 

individual named in the record upon 

his or her request. The accountings must 

state the date, nature, and purpose of 

each disclosure of the record and the 

name and address of the recipient. 

(i) The application of this provision 

would impair the ability of law 

enforcement agencies outside the 

Department of the Treasury to make 

effective use of information provided by 

the Department. Making accountings of 

disclosures available to the subjects of 

an investigation would alert them to the 

fact that another agency is conducting 

an investigation into their criminal 

activities and could reveal the 

geographic location of the other 

agency’s investigation, the nature and 

purpose of that investigation, and the 

dates on which that investigation was 

active. Individuals possessing such 

knowledge would be able to take 

measures to avoid detection or 

apprehension by altering their 

operations, by transferring their 

criminal activities to other geographical 

areas, or by destroying or concealing 


khammond on DSKJM1Z7X2PROD with RULES
88818 Federal Register / Vol. 88, No. 246 / Tuesday, December 26, 2023 / Rules and Regulations 

evidence that would form the basis for 

arrest. In the case of a delinquent 

account, such release might enable the 

subject of the investigation to dissipate 

assets before levy. 

(ii) Moreover, providing accountings 

to the subjects of investigations would 

alert them to the fact that the 

Department has information regarding 

their criminal activities and could 

inform them of the general nature of that 

information. Access to such information 

could reveal the operation of the 

Department’s information-gathering and 

analysis systems and permit individuals 

to take steps to avoid detection or 

apprehension. 

(5) 5 U.S.C. 552(c)(4) requires an 

agency to inform any person or other 

agency about any correction or notation 

of dispute that the agency made in 

accordance with 5 U.S.C. 552a(d) to any 

record that the agency disclosed to the 

person or agency if an accounting of the 

disclosure was made. Since this 

provision depends on an individual’s 

having access to and an opportunity to 

request amendment of records 

pertaining to him or her, and since these 

rules exempt the systems of records 

from the provisions of the Privacy Act 

relating to access to and amendment of 

records, for the reasons set out in 

paragraph (f)(3) of this section, this 

provision should not apply to the 

systems of records. 

(6) 5 U.S.C. 552a(e)(4)(I) requires an 

agency to publish a general notice 

listing the categories of sources for 

information contained in a system of 

records. The application of this 

provision to the systems of records 

could compromise the Department’s 

ability to provide useful information to 

law enforcement agencies, since 

revealing sources for the information 

could: 

(i) Disclose investigative techniques 

and procedures; 

(ii) Result in threats or reprisals 

against informants by the subjects of 

investigations; and 

(iii) Cause informants to refuse to give 

full information to criminal 

investigators for fear of having their 

identities as sources disclosed. 

(7) 5 U.S.C. 552a(e)(1) requires an 

agency to maintain in its records only 

such information about an individual as 

is relevant and necessary to accomplish 

a purpose of the agency required to be 

accomplished by statute or Executive 

order. The term maintain, as defined in 

5 U.S.C. 552a(a)(3), includes collect and 

disseminate. The application of this 

provision to the systems of records 

could impair the Department’s ability to 

collect and disseminate valuable law 

enforcement information. 

(i) In many cases, especially in the 

early stages of investigation, it may be 

impossible to immediately determine 

whether information collected is 

relevant and necessary, and information 

that initially appears irrelevant and 

unnecessary often may, upon further 

evaluation or upon collation with 

information developed subsequently, 

prove particularly relevant to a law 

enforcement program. 

(ii) Not all violations of law 

discovered by the Department fall 

within the investigative jurisdiction of 

the Department of the Treasury. To 

promote effective law enforcement, the 

Department will have to disclose such 

violations to other law enforcement 

agencies, including State, local, and 

foreign agencies, that have jurisdiction 

over the offenses to which the 

information relates. Otherwise, the 

Department might be placed in the 

position of having to ignore information 

relating to violations of law not within 

the jurisdiction of the Department of the 

Treasury when that information comes 

to the Department’s attention during the 

collation and analysis of information in 

its records. 

(8) 5 U.S.C. 552a(e)(2) requires an 

agency to collect information to the 

greatest extent practicable directly from 

the subject individual when the 

information may result in adverse 

determinations about an individual’s 

rights, benefits, and privileges under 

Federal programs. The application of 

this provision to the systems of records 

would impair the Department’s ability 

to collate, analyze, and disseminate 

investigative, intelligence, and 

enforcement information. 

(i) Most information collected about 

an individual under criminal 

investigation is obtained from third 

parties, such as witnesses and 

informants. It is usually not feasible to 

rely upon the subject of the 

investigation as a source for information 

regarding his criminal activities. 

(ii) An attempt to obtain information 

from the subject of a criminal 

investigation will often alert that 

individual to the existence of an 

investigation, thereby affording the 

individual an opportunity to attempt to 

conceal his criminal activities so as to 

avoid apprehension. 

(iii) In certain instances, the subject of 

a criminal investigation may assert his/ 

her constitutional right to remain silent 

and refuse to supply information to 

criminal investigators upon request. 

(iv) During criminal investigations it 

is often a matter of sound investigative 

procedure to obtain information from a 

variety of sources to verify information 

already obtained from the subject of a 

criminal investigation or other sources. 

(9) 5 U.S.C. 552a(e)(3) requires an 

agency to inform each individual whom 

it asks to supply information, on the 

form that it uses to collect the 

information or on a separate form that 

the individual can retain, of the 

agency’s authority for soliciting the 

information; whether disclosure of 

information is voluntary or mandatory; 

the principal purposes for which the 

agency will use the information; the 

routine uses that may be made of the 

information; and the effects on the 

individual of not providing all or part of 

the information. The systems of records 

should be exempted from this provision 

to avoid impairing the Department’s 

ability to collect and collate 

investigative, intelligence, and 

enforcement data. 

(i) Confidential sources or undercover 

law enforcement officers often obtain 

information under circumstances in 

which it is necessary to keep the true 

purpose of their actions secret so as not 

to let the subject of the investigation or 

his or her associates know that a 

criminal investigation is in progress. 

(ii) If it became known that the 

undercover officer was assisting in a 

criminal investigation, that officer’s 

physical safety could be endangered 

through reprisal, and that officer may 

not be able to continue working on the 

investigation. 

(iii) Individuals often feel inhibited in 

talking to a person representing a 

criminal law enforcement agency but 

are willing to talk to a confidential 

source or undercover officer whom they 

believe are not involved in law 

enforcement activities. 

(iv) Providing a confidential source of 

information with written evidence that 

he or she was a source, as required by 

this provision, could increase the 

likelihood that the source of information 

would be subject to retaliation by the 

subject of the investigation. 

(v) Individuals may be contacted 

during preliminary information 

gathering, surveys, or compliance 

projects concerning the administration 

of the internal revenue laws before any 

individual is identified as the subject of 

an investigation. Informing the 

individual of the matters required by 

this provision would impede or 

compromise subsequent investigations. 

(10) 5 U.S.C. 552a(e)(5) requires an 

agency to maintain all records it uses in 

making any determination about any 

individual with such accuracy, 

relevance, timeliness, and completeness 

as is reasonably necessary to assure 

fairness to the individual in the 

determination. 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 88, No. 246 / Tuesday, December 26, 2023 / Rules and Regulations 88819 

(i) Since 5 U.S.C. 552a(a)(3) defines 

maintain to include collect and 

disseminate, application of this 

provision to the systems of records 

would hinder the initial collection of 

any information that could not, at the 

moment of collection, be determined to 

be accurate, relevant, timely, and 

complete. Similarly, application of this 

provision would seriously restrict the 

Department’s ability to disseminate 

information pertaining to a possible 

violation of law-to-law enforcement and 

regulatory agencies. In collecting 

information during a criminal 

investigation, it is often impossible or 

unfeasible to determine accuracy, 

relevance, timeliness, or completeness 

prior to collection of the information. In 

disseminating information to law 

enforcement and regulatory agencies, it 

is often impossible to determine 

accuracy, relevance, timeliness, or 

completeness prior to dissemination 

because the Department may not have 

the expertise with which to make such 

determinations. 

(ii) Information that may initially 

appear inaccurate, irrelevant, untimely, 

or incomplete may, when collated and 

analyzed with other available 

information, become more pertinent as 

an investigation progresses. In addition, 

application of this provision could 

seriously impede criminal investigators 

and intelligence analysts in the exercise 

of their judgment in reporting results 

obtained during criminal investigations. 

(11) 5 U.S.C. 552a(e)(8) requires an 

agency to make reasonable efforts to 

serve notice on an individual when the 

agency makes any record on the 

individual available to any person 

under compulsory legal process, when 

such process becomes a matter of public 

record. The systems of records should 

be exempted from this provision to 

avoid revealing investigative techniques 

and procedures outlined in those 

records and to prevent revelation of the 

existence of an ongoing investigation 

where there is need to keep the 

existence of the investigation secret. 

(12) 5 U.S.C. 552a(g) provides for civil 

remedies to an individual when an 

agency wrongfully refuses to amend a 

record or to review a request for 

amendment, when an agency 

wrongfully refuses to grant access to a 

record, when an agency fails to maintain 

accurate, relevant, timely, and complete 

records which are used to make a 

determination adverse to the individual, 

and when an agency fails to comply 

with any other provision of the Privacy 

Act so as to adversely affect the 

individual. The systems of records 

should be exempted from this provision 

to the extent that the civil remedies may 

relate to provisions of the Privacy Act 

from which these rules exempt the 

systems of records, since there should 

be no civil remedies for failure to 

comply with provisions from which the 

Department is exempted. Exemption 

from this provision will also protect the 

Department from baseless civil court 

actions that might hamper its ability to 

collate, analyze, and disseminate 

investigative, intelligence, and law 

enforcement data. 

(e) Specific exemptions under 5 

U.S.C. 552a(k)(1). (1) Under 5 U.S.C. 

552a(k)(1), the head of any agency may 

promulgate rules to exempt any system 

of records within the agency from 

certain provisions of the Privacy Act to 

the extent that the system contains 

information subject to the provisions of 

5 U.S.C. 552(b)(1). This paragraph (e) 

applies to the following systems of 

records maintained by the Department 

of the Treasury: 

(i) Treasury-wide.

(2) The Department hereby exempts 

the systems of records listed in 

paragraphs (g)(1)(i) through (ix) of this 

section from the following provisions of 

the Privacy Act, pursuant to 5 U.S.C. 

552a(k)(2): 5 U.S.C. 552a(c)(3), 5 U.S.C. 

552a(d)(1), (2), (3), (4), 5 U.S.C. 

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

and (I), and 5 U.S.C. 552a(f). 

(h) Reasons for exemptions under 5 

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

requires an agency to make accountings 

of disclosures of a record available to 

the individual named in the record 

upon his or her request. The 

accountings must state the date, nature, 

and purpose of each disclosure of the 

record and the name and address of the 

recipient. 

(i) The application of this provision 

would impair the ability of the 

Department of the Treasury and of law 

enforcement agencies outside the 

Department to make effective use of 

information maintained by the 

Department. Making accountings of 

disclosures available to the subjects of 

an investigation would alert them to the 

fact that an agency is conducting an 

investigation into their illegal activities 

and could reveal the geographic location 

of the investigation, the nature and 

purpose of that investigation, and the 

dates on which that investigation was 

active. Individuals possessing such 

knowledge would be able to take 

measures to avoid detection or 

apprehension by altering their 

operations, by transferring their illegal 

activities to other geographical areas, or 

by destroying or concealing evidence 

that would form the basis for detection 

or apprehension. In the case of a 

delinquent account, such release might 

enable the subject of the investigation to 

dissipate assets before levy. 

(ii) Providing accountings to the 

subjects of investigations would alert 

them to the fact that the Department has 

information regarding their illegal 

activities and could inform them of the 

general nature of that information. 

(2) 5 U.S.C. 552a(d)(1), (e)(4)(H) and 

(f)(2), (3), and (5) grant individuals 

access to records pertaining to them. 

The application of these provisions to 

the systems of records would 

compromise the Department’s ability to 

utilize and provide useful tactical and 

strategic information to law enforcement 

agencies. 

(i) Permitting access to records 

contained in the systems of records 

would provide individuals with 

information concerning the nature of 

any current investigations and would 

enable them to avoid detection or 

apprehension by: 

(A) Discovering the facts that would 

form the basis for their detection or 

apprehension; 

(B) Enabling them to destroy or alter 

evidence of illegal conduct that would 

form the basis for their detection or 

apprehension; and 

(C) Using knowledge that 

investigators had reason to believe that 

a violation of law was about to be 

committed, to delay the commission of 

the violation or commit it at a location 

that might not be under surveillance. 

(ii) Permitting access to either ongoing or closed investigative files would 

also reveal investigative techniques and 

procedures, the knowledge of which 

could enable individuals planning noncriminal acts to structure their 

operations so as to avoid detection or 

apprehension. 

(iii) Permitting access to investigative 

files and records could, moreover, 

disclose the identity of confidential 

sources and informants and the nature 

of the information supplied and thereby 

endanger the physical safety of those 

sources by exposing them to possible 

reprisals for having provided the 

information. Confidential sources and 

informants might refuse to provide 

investigators with valuable information 

unless they believed that their identities 

would not be revealed through 

disclosure of their names or the nature 

of the information they supplied. Loss 

of access to such sources would 

seriously impair the Department’s 

ability to carry out its mandate. 

(iv) Furthermore, providing access to 

records contained in the systems of 

records could reveal the identities of 

undercover law enforcement officers or 

other persons who compiled 

information regarding the individual’s 

illegal activities and thereby endanger 

the physical safety of those undercover 

officers, persons, or their families by 

exposing them to possible reprisals. 

(v) By compromising the law 

enforcement value of the systems of 

records for the reasons outlined in 

paragraphs (h)(2)(i) through (iv) of this 

section, permitting access in keeping 

with these provisions would discourage 

other law enforcement and regulatory 

agencies, foreign and domestic, from 

freely sharing information with the 

Department and thus would restrict the 

Department’s access to information 

necessary to accomplish its mission 

most effectively. 

(vi) Finally, the dissemination of 

certain information that the Department 

may maintain in the systems of records 

is restricted by law. 

(3) 5 U.S.C. 552a(d)(2), (3), and (4), 

(e)(4)(H), and (f)(4) permit an individual 

to request amendment of a record 

pertaining to him or her and require the 

agency either to amend the record, or to 

note the disputed portion of the record 

and to provide a copy of the 

individual’s statement of disagreement 

with the agency’s refusal to amend a 

record to persons or other agencies to 

whom the record is thereafter disclosed. 

Since these provisions depend on the 

individual having access to his or her 

records, and since these rules exempt 

the systems of records from the 

provisions of the Privacy Act relating to 

access to records, these provisions 

should not apply to the systems of 

records for the reasons set out in 

paragraph (h)(2) of this section. 

(4) 5 U.S.C. 552a(e)(1) requires an 

agency to maintain in its records only 

such information about an individual as 

is relevant and necessary to accomplish 

a purpose of the agency required by 

statute or Executive order. The term 

maintain, as defined in 5 U.S.C. 

552a(a)(3), includes collect and 

disseminate. The application of this 

provision to the system of records could 

impair the Department’s ability to 

collect, utilize and disseminate valuable 

law enforcement information. 

(i) In many cases, especially in the 

early stages of investigation, it may be 

impossible immediately to determine 

whether information collected is 

relevant and necessary, and information 

that initially appears irrelevant and 

unnecessary often may, upon further 

evaluation or upon collation with 

information developed subsequently, 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 88, No. 246 / Tuesday, December 26, 2023 / Rules and Regulations 88823 

prove particularly relevant to a law 

enforcement program. 

(ii) Not all violations of law 

discovered by the Department analysts 

fall within the investigative jurisdiction 

of the Department of the Treasury. To 

promote effective law enforcement, the 

Department will have to disclose such 

violations to other law enforcement 

agencies, including State, local, and 

foreign agencies that have jurisdiction 

over the offenses to which the 

information relates. Otherwise, the 

Department might be placed in the 

position of having to ignore information 

relating to violations of law not within 

the jurisdiction of the Department of the 

Treasury when that information comes 

to the Department’s attention during the 

collation and analysis of information in 

its records. 

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

enable individuals to inquire whether a 

system of records contains records 

pertaining to them. Application of these 

provisions to the systems of records 

would allow individuals to learn 

whether they have been identified as 

suspects or subjects of investigation. As 

further described in paragraphs (h)(5)(i) 

through (vi) of this section, access to 

such knowledge would impair the 

Department’s ability to carry out its 

mission, since individuals could: 

(i) Take steps to avoid detection; 

(ii) Inform associates that an 

investigation is in progress; 

(iii) Learn the nature of the 

investigation; 

(iv) Learn whether they are only 

suspects or identified as law violators; 

(v) Begin, continue, or resume illegal 

conduct upon learning that they are not 

identified in the system of records; or 

(vi) Destroy evidence needed to prove 

the violation. 

(6) 5 U.S.C. 552a(e)(4)(I) requires an 

agency to publish a general notice 

listing the categories of sources for 

information contained in a system of 

records. The application of this 

provision to the systems of records 

could compromise the Department’s 

ability to complete or continue 

investigations or to provide useful 

information to law enforcement 

agencies, since revealing sources for the 

information could: 

(i) Disclose investigative techniques 

and procedures; 

(ii) Result in threats or reprisals 

against informants by the subjects of 

investigations; and 

(iii) Cause informants to refuse to give 

full information to investigators for fear 

of having their identities as sources 

disclosed. 

(i) Specific exemptions under 5 U.S.C. 

552a(k)(4). (1) Under 5 U.S.C. 

552a(k)(4), the head of any agency may 

promulgate rules to exempt any system 

of records within the agency from 

certain provisions of the Privacy Act if 

the system is required by statute to be 

maintained and used solely as statistical 

records. This paragraph (i) applies to the 

following system of records maintained 

by the Department, for which exemption 

is claimed under 5 U.S.C. 552a(k)(4). 

(i) Treasury-wide.

(2) The Department hereby exempts 

the system of records listed in paragraph 

(i)(1) of this section from the following 

provisions of the Privacy Act, pursuant 

to 5 U.S.C. 552a(k)(4): 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(e)(4)(G), (H), and (I), and 5 U.S.C. 

552a(f). 

(3) The system of records is 

maintained under 26 U.S.C. 6108, 

which requires that the Secretary or his 

delegate prepare and publish annually 

statistics reasonably available with 

respect to the operation of the income 

tax laws, including classifications of 

taxpayers and of income, the amounts 

allowed as deductions, exemptions, and 

credits, and any other facts deemed 

pertinent and valuable. 

(j) Reasons for exemptions under 5 

U.S.C. 552a(k)(4). The reason for 

exempting the system of records is that 

disclosure of statistical records 

(including release of accounting for 

disclosures) would in most instances be 

of no benefit to a particular individual 

since the records do not have a direct 

effect on a given individual. 

(k) Specific exemptions under 5 

U.S.C. 552a(k)(5). (1) Under 5 U.S.C. 

552a(k)(5), the head of any agency may 

promulgate rules to exempt any system 

of records within the agency from 

certain provisions of the Privacy Act if 

the system is investigatory material 

compiled solely for the purpose of 

determining suitability, eligibility, and 

qualifications for Federal civilian 

employment or access to classified 

information, but only to the extent that 

the disclosure of such material would 

reveal the identity of a source who 

furnished information to the 

Government under an express promise 

that the identity of the source would be 

held in confidence, or, prior to 

September 27, 1975, under an implied 

promise that the identity of the source 

would be held in confidence. Thus, to 

the extent that the records in this system 

can be disclosed without revealing the 

identity of a confidential source, they 

are not within the scope of this 

exemption and are subject to all the 

requirements of the Privacy Act. This 

paragraph (j) applies to the following 

systems of records maintained by the 

Department or one of its bureaus: 

(i) Treasury-wide.

(2) The Department hereby exempts 

the systems of records listed in 

paragraphs (k)(1)(i) and (ii) of this 

section from the following provisions of 

the Privacy Act, pursuant to 5 U.S.C. 

552a(k)(5): 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(e)(4)(G), (H), 

and (I), and 5 U.S.C. 552a(f). 

(l) Reasons for exemptions under 5 

U.S.C. 552a(k)(5). (1) The sections of 5 

U.S.C. 552a from which the systems of 

records are exempt include in general 

those providing for individuals’ access 

to or amendment of records. When such 

access or amendment would cause the 

identity of a confidential source to be 

revealed, it would impair the future 

ability of the Department to compile 

investigatory material for the purpose of 

determining suitability, eligibility, or 

qualifications for Federal civilian 

employment, Federal contracts, or 

access to classified information. In 

addition, the systems shall be exempt 

from 5 U.S.C. 552a(e)(1) which requires 

that an agency maintain in its records 

only such information about an 

individual as is relevant and necessary 

to accomplish a purpose of the agency 

required to be accomplished by statute 

or executive order. The Department 

believes that to fulfill the requirements 

of 5 U.S.C. 552a(e)(1) would unduly 

restrict the agency in its information 

gathering inasmuch as it is often not 

until well after the investigation that it 

is possible to determine the relevance 

and necessity of particular information. 

(2) If any investigatory material 

contained in the above-named systems 

becomes involved in criminal or civil 

matters, exemptions of such material 

under 5 U.S.C. 552a(j)(2) or (k)(2) is 

hereby claimed. 

(m) Exemption under 5 U.S.C. 

552a(k)(6). (1) Under 5 U.S.C. 

552a(k)(6), the head of any agency may 

promulgate rules to exempt any system 

of records that is testing, or examination 

material used solely to determine 

individual qualifications for 

appointment or promotion in the 

Federal service the disclosure of which 

would compromise the objectivity or 

fairness of the testing or examination 

process. This paragraph (m) applies to 

the following system of records 

maintained by the Department, for 

which exemption is claimed under 5 

U.S.C. 552a(k)(6). 

(i) Treasury-wide.

(ii) [Reserved] (2) The Department hereby exempts 

the system of records listed in paragraph 

(m)(1) of this section from the following 

provisions of the Privacy Act, pursuant 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 88, No. 246 / Tuesday, December 26, 2023 / Rules and Regulations 88825 

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(e)(4)(G), (H), and (I), and 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.

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.

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
