---------------------------------------------------------------------------

    \1\ On December 22, 2021, EPA proposed to withdraw and 
reconsider the October 1, 2020, SAFETEA approval. See https://www.epa.gov/ok/proposed-withdrawal-and-reconsideration-and-supporting-information. EPA is engaging in further consultation with 
tribal governments and expects to have discussions with the State of 
Oklahoma as part of this reconsideration. EPA also notes that the 
October 1, 2020, approval is the subject of a pending challenge in 
federal court. Pawnee Nation of Oklahoma v Regan, No. 20-9635 (10th 
Cir.). EPA may make further changes to the approval of Oklahoma's 
program to reflect the outcome of the proposed withdrawal and 
reconsideration of the October 1, 2020, SAFETEA approval. Pending 
completion of EPA's review, EPA is proceeding with notice of this 
proposed permit in accordance with the October 1, 2020, approval. 
EPA's final action on this permit will address the scope of coverage 
of this permit with respect to Indian country which may require 
appropriate adjustments, based on the status of our review of the 
SAFETEA approval. If EPA issues a final permit before our review of 
the SAFETEA approval is complete, EPA may reopen this the permit to 
make further changes to the scope of coverage to reflect the outcome 
of the SAFETEA review.

B. What action is the EPA taking?

    The EPA is providing notice of the final NPDES Permit Issuance for 
discharges from Hydrostatic Testing of New and Existing Vessels in New 
Mexico (NMG270000), Oklahoma (OKG27F000), and Indian Country within the 
States of Texas, Oklahoma, New Mexico, and Louisiana (TXG27I000, 
OKG27I000, NMG27I000, & LAG27I000).

C. What is the EPA's authority for taking this action?

    Section 301 (a) of the Clean Water Act (CWA or the Act), 33 U.S.C. 
1311 (a), prohibits the discharge of pollutants to waters of the United 
States in the absence of authorizing permits. CWA section 402, 33 
U.S.C. 1342, authorizes EPA to issue National Pollutant Discharge 
Elimination System (NPDES) permits allowing discharges on condition 
they will meet certain requirements, including CWA sections 301, 304, 
306, 401 (33 U.S.C. 1331, 1314, and 1341) and 403. Those statutory 
provisions state that NPDES permits must include effluent limitations 
requiring authorized discharges to: (1) meet standards reflecting 
levels of technological capability, (2) comply with EPA-approved state 
water quality standards, and (3) comply with other state requirements 
adopted under authority retained by states under CWA 510, 33 U.S.C. 
1370.
    Two types of technology-based effluent limitations must be included 
in the permit proposed here. With regard to conventional pollutants 
(i.e., pH, biochemical oxygen demand (BOD), oil and grease, TSS, and 
fecal coliform), CWA section 301(b)(2)(E) requires effluent limitations 
based on ``best conventional pollution control technology'' (BCT). With 
regard to non-conventional and toxic pollutants, CWA section 
301(b)(2)(A), (C), and (D) require effluent limitations based on ``best 
available pollution control technology economically achievable'' (BAT), 
a standard which generally represents the best performing existing 
technology in an industrial category or subcategory. BAT and BCT 
effluent limitations may never be less stringent than corresponding 
effluent limitations based on best practicable control technology 
(BPT), a standard applicable to similar discharges prior to March 31, 
1989, under CWA 301(b)(1)(A).
    Frequently, EPA adopts nationally applicable guidelines identifying 
the BPT, BCT, and BAT standards to which specific industrial categories 
and subcategories are subject. There are no national guidelines for the 
activities authorized in the final permit. National Guidelines 
establishing BPT, BCT, and BAT standards have not been promulgated for 
discharges from the

[[Page 14165]]

hydrostatic testing of vessels. The BCT and BAT requirements for these 
discharges have, therefore, been established using BPJ, as required by 
CWA section 402(a)(1). Until such guidelines are published, CWA section 
402(a)(1) requires that EPA determine appropriate BCT and BAT effluent 
limitations in its NPDES permitting actions on the basis of its best 
professional judgment (BPJ).
    Department of Transportation regulations 49 CFR Subchapter D, Part 
192, prescribe minimum safety requirements for pipeline facilities and 
the transportation of gas. Part 192, Subpart J, prescribes minimum 
leak-test and strength test requirements for pipelines where the test 
medium must be liquid, air, natural gas, or inert gas. Part 192.515(b) 
states that the operator shall insure that the test medium is disposed 
of in a manner that will minimize damage to the environment. 49 CFR 
part 195 prescribes the transportation of hazardous liquids by 
pipeline.
    The Agency may issue ``general permits'' applicable to a class of 
similar discharges within a discreet geographical area. See NRDC v. 
Costle, 568 F.2d 1369 (D.C. Cir. 1977) and 40 CFR 122.28. Issuance of 
such permits is not controlled by the procedural rules EPA uses for 
individual permits but is instead subject to section 4 of the 
Administrative Procedure Act (APA), 5 U.S.C. 553, as supplemented by 
EPA regulations. EPA must, however, comply with the substantive 
requirements of the CWA without regard to whether it is issuing an 
individual or general NPDES permit.

II. Public Notification Information

A. Public Notice of the Hydrostatic Test General Permit

    On April 27, 2022, the EPA, Region 6, commenced the public comment 
period for the (NPDES) general permit authorizing discharges resulting 
from the hydrostatic testing of new and existing vessels (e.g., 
pipelines, storage tanks, etc.) in New Mexico (NMG270000) and Oklahoma 
(OKG27F000). This authorization also covers Indian Country within the 
States of Texas, Oklahoma, New Mexico, and Louisiana (TXG27I000, 
OKG27I000, NMG27I000, & LAG27I000) [EPA-R06-OW-2022-0371; FRL-9257-01-
R6].
    The notice was also published at https://www.epa.gov/publicnotices.

B. Public Process

    The EPA Region 6 opened a 60-day public comment period on April 27, 
2022, that ended on June 27, 2022 (11:59 p.m. CST).
    EPA held a virtual information Tribal Consultation session via 
TEAMS on May 18, 2022, with tribal environmental staff at which EPA 
explained the basis for the general permit and answered any question 
that the tribe had.
    All comments received by the EPA were considered and responded by 
the EPA with the final general permit. Information about the Factsheet 
and draft permit are available at www.regulations.gov, Docket ID. No 
EPA-R06-OW-2022-0371.

III. Summary of Responses to Comments and Clean Water Act Section 401 
Certifications

    The EPA received 15 written comments from the New Mexico 
Environment Department. These comments are mostly specific to the New 
Mexico Water Quality Standards. One major comment was on the request to 
include operational information in the hydrostatic test monitoring 
records. The requested monitoring records are:

a. Start/stop time of testing
b. Duration of discharge
c. Volume of discharge
d. Source water of hydrostatic test water
e. Disposition location

    After due consideration, EPA included the above requested operation 
information in Part I, Section E of the final permit.
    EPA also received Conditions of Certifications from the New Mexico 
Environment Department, Oklahoma Department of Environmental Quality, 
all the Region 6 Tribes with CWA Certification Authority except the 
Pueblo of Laguna and the Pueblo of Acoma. The final permit excluded 
discharges on the Pueblo of Laguna and the Pueblo of Acoma from this 
general permit because these two Pueblos denied CWA certification.
    Changes from the draft permit to implement e-reporting and e-filing 
of NOIs have been made to the final permit under the Minor Modification 
procedures at 40 CFR 122.63(f).
    Additional details of the comments received, and responses are 
available at www.regulations.gov or at https://www.epa.gov/publicnotices.
Authority
    This action is taken under the authority of section 402 of the 
Clean Water Act as amended, 33 U.S.C. 1342. I hereby provide public 
notice of the EPA's final action authorizing the NPDES General Permit 
for Discharges from Hydrostatic Testing of New and Existing Vessels in 
New Mexico (NMG270000), Oklahoma (OKG27F000), and Indian Country within 
the States of Texas, Oklahoma, New Mexico, and Louisiana (TXG27I000, 
OKG27I000, NMG27I000, & LAG27I000).
