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.

By this Order, the Commission makes rule changes to part 1 of the Commission’s rules, and amends its Schedule of Application Fees, 47 CFR 1.1102 through 1.1109, as listed in the Rule Changes section, to adjust its fees for processing applications and other filings. Section 8(a) of the Communications Act of 1934, as amended (‘‘the Act’’), requires the Commission to ‘‘assess and collect application fees at such rates as the Commission shall establish or at such modified rates as it shall establish pursuant to’’ Section 8(b).1 Section 8(g) contains the Schedule of Charges for a broad range of application categories as well as procedures for modifying and collecting these charges.2 Section 8(b)(1) 1 47 U.S.C. 158(a). RAY BAUM’s Act of 2018 amended Section 8 of the Communications Act and provided an effective date of October 1, 2018 for such changes. Consolidated Appropriations Act, 2018, Division P—RAY BAUM’s Act of 2018, Title I, FCC Reauthorization, Public Law 115–141 (March 23, 2 The PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 requires that the Schedule of Application Fees ‘‘be reviewed by the Commission every two years after October 1, 1991, and adjusted by the Commission to reflect changes in the Consumer Price Index.’’ As required by Section 8(b)(1), this Order increases application fees to reflect the net change in the Consumer Price Index for all Urban Consumers (‘‘CPI–U’’) of 3.7 percent, an increase of 8.825 index points calculated from October 2015 (237.838) to October 2017 (246.663).3 2018). Congress envisioned a transition between fees adopted before and after the effective date of the amendments to Section 8. In particular, Congress provided that application fees in effect on the day before the effective date of the RAY BAUM’s Act shall remain in effect until such time as the Commission adjusts or amends such fee. Id. Section 8 fees are revised every even year and the Commission expects that this Order will become effective before October 1, 2018. We also note that in a separate proceeding, the Commission proposed to assess a small satellite application fee of $30,000.00 under the RAY BAUM’s Act. See Streamlining Licensing Procedures for Small Satellites, Notice of Proposed Rulemaking, IB Docket No. 18–86, FCC 18–44, para. 76 (2018). In this Order, the Commission does not address this proposal. 3 Application fees are calculated based upon the process set forth in 47 U.S.C. 158(b)(1). The increase in the CPI–U between October 2015 (the month used to calculate the last CPI–U adjustment of the Schedule of Application Fees) and October 2017 is 8.825 index points, a 3.7 percent increase. Section 8(b)(1) prescribes that increases or decreases in application fees are to be ‘‘determined by the net change in the Consumer Price Index E:\FR\FM\03AUR1.SGM Continued 03AUR1

Addition of a Subsurface Intrusion Component to the Hazard 
Ranking System; Corrections

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.

FOR FURTHER INFORMATION CONTACT: Terry Jeng, phone: (703) 603-8852, 
email: [email protected], Site Assessment and Remedy Decisions Branch, 
Assessment and Remediation Division, Office of Superfund Remediation 
and Technology Innovation (Mailcode 5204P), U.S. Environmental 
Protection Agency, 1200 Pennsylvania Avenue NW, Washington, DC 20460.

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

[[Page 38037]]

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.
