would prompt the addition of 

manufacturers (including importers) to 

the final lists, then EPA plans to first 

notify those manufacturers (including 

importers). 

EPA expects the final lists will 

indicate whether any manufacturers 

were identified in error, any additional 

manufacturers that were identified 

through the comment period or selfidentification process, and whether any 

manufacturers have certified that they 

have already ceased manufacture 

(including import) prior to the cutoff 

date of December 18, 2023, and will not 

manufacture the subject chemical 

substance for five years. The final list 

will be published no later than 

concurrently with the final scope 

document for each risk evaluation 

initiated by EPA under TSCA section 6 

for these five High-Priority Substances.

[Docket No. FRA–2024–0033, Notice No. 3] 

RIN 2130–AC97 

Federal Railroad Administration’s 

Procedures for Waivers and SafetyRelated Proceedings; Withdrawal 

AGENCY: Federal Railroad 

Administration (FRA), U.S. Department 

of Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM); withdrawal. 

SUMMARY: FRA is withdrawing the 

October 29, 2024, NPRM that proposed 

to update FRA’s procedures for waivers 

and safety-related proceedings to define 

the two components of the statutory 

waiver and suspension standard, ‘‘in the 

public interest’’ and ‘‘consistent with 

railroad safety.’’ 

DATES: The NPRM published at 89 FR 

85895 on October 29, 2024, is 

withdrawn as of December 31, 2024. 

FOR FURTHER INFORMATION CONTACT: 

Veronica Chittim, Senior Attorney, 

Office of the Chief Counsel, at 

veronica.chittim@dot.gov, 202–480– 

3410; or Lucinda Henriksen, Senior 

Advisor, Office of Railroad Safety, at 

lucinda.henriksen@dot.gov, 202–657– 

2842. 

SUPPLEMENTARY INFORMATION: 

Background 

This action withdraws an NPRM 

published in the Federal Register on 

October 29, 2024 (89 FR 85895), that 

proposed to update FRA’s procedures 

for waivers and safety-related 

proceedings to define the two 

components of the statutory waiver and 

suspension standard, ‘‘in the public 

interest’’ and ‘‘consistent with railroad 

safety.’’ The NPRM’s comment period is 

scheduled to close on January 15, 2025. 

Reason for Withdrawal 

In light of resource constraints to 

address the numerous rail safety matters 

before the agency and because FRA has 

previously issued guidance on the 

subject matter covered by the NPRM,1

FRA has decided to withdraw the 

NPRM. FRA may pursue similar 

regulations in the future and will 

consider updating the existing guidance. 

Despite the decision not to move 

forward with the proposed rule at this 

time, FRA appreciates and takes 

seriously the thoughtful perspectives 

raised by stakeholders concerning the 

waiver process. FRA will continue 

engaging with its stakeholders on all rail 

safety matters. 

Conclusion 

The NPRM published in the Federal 

Register on October 29, 2024 (89 FR 

85895), is hereby withdrawn. 

Authority: 49 U.S.C. 20103, 20107, 

20114, 20306, 20502–20504, and 49 CFR 

1.89.

Chief Counsel.
