AGENCY:
Environmental Protection Agency (EPA).
ACTION:
Correcting amendments.
SUMMARY:
On January 9, 2017, the Environmental Protection Agency published a final rule which added subsurface intrusion component to the Superfund Hazard Ranking System. That document inadvertently failed to update the Table of Contents and contained a few other typographical errors. This document corrects the final regulation.
DATES:
This correction is effective August 3, 2018.

SUPPLEMENTARY INFORMATION:
This is EPA's erratum to the final rule titled Addition of a Subsurface Intrusion Component to the Hazard Ranking System, published January 9, 2017 (82 FR 2760). This is the second set of corrections. The first set of corrections was published in the Federal Register on January 31, 2018 (83 FR 4430). This document augments those corrections.
Section 553 of the Administrative Procedure Act (APA), 5 U.S.C. 553(b)(3)(B), provides that, when an agency for good cause finds that notice and public procedure are impracticable, unnecessary, or contrary to the public interest, the agency may issue a rule without providing notice and an opportunity for public comment. See Utility Solid Waste Activities Group v. EPA, 236 F.3d 749, 752 (D.C. Cir. 2001). We have determined that there is good cause for making these correcting amendments final without prior proposal and opportunity for public comment. Notice and comment is unnecessary because these administrative or clerical corrections govern the methodology of how EPA, rather than the public or industry, evaluates contaminated sites under the Hazard Ranking System. Similarly, notice and comment is impracticable and contrary to the public interest because the correcting amendments will more quickly ensure that EPA is following the proper procedures to evaluate potential threats to public health from releases of hazardous substances, pollutants, or contaminants. Thus, good cause exists to proceed without notice and public comment.
These correcting amendments are effective immediately upon publication. Section 553(d) of the APA, 5 U.S.C. 553(d), provides that final rules shall not become effective until 30 days after publication in the Federal Register, “except . . . as otherwise provided by the agency for good cause,” among other exceptions. The purpose of this provision is to “give affected parties a reasonable time to adjust their behavior before the final rule takes effect.” Omnipoint Corp. v. FCC, 78 F.3d 620, 630 (D.C. Cir. 1996); see also United States v. Gavrilovic, 551 F.2d 1099, 1104 (8th Cir. 1977) (quoting legislative history). Thus, in determining whether good cause exists to waive the 30-day delay, an agency should “balance the necessity for immediate implementation against principles of fundamental fairness which require that all affected persons be afforded a reasonable amount of time to prepare for the effective date of its ruling.” Gavrilovic, 551 F.2d at 1105. EPA has determined that there is good cause for making these correcting amendments effective immediately because, as stated above, the corrections govern how EPA, rather than the public or industry, applies the Hazard Ranking System to evaluate potential threats to public health from releases of hazardous substances, pollutants, or contaminants. Accordingly, EPA finds that good cause exists under section 553(d)(3) to make this rule effective immediately upon publication.
