Federal Register / Vol. 86, No. 38 / Monday, March 1, 2021 / Notices West, Room 3334, 1301 Constitution Ave. NW, Washington, DC. The telephone number for the Docket Center is 2025661744. For additional information about EPAs public docket, visit http www.epa.gov/dockets.
Abstract: Regulations implementing section 301h of the Clean Water Act CWA are found at 40 CFR part 125, subpart G. This CWA section allows for a case-by-case review of treatment requirements for publicly owned treatment works POTW discharges to marine waters. Eligible POTW
applicants that met the set of environmentally stringent criteria received a modified National Pollutant Discharge Elimination System NPDES
permit waiving secondary treatment requirements. CWA section 301h only applies to the 25 POTWs that applied by December 29, 1982, that currently hold modified permits and the six states in which the POTWs are located. No new applications are accepted.
The CWA section 301h program involves collecting information from municipal wastewater treatment facilities POTWs, and the state in which the POTW is located. A POTW
holding a modified permit or reapplying for a modification provides application, monitoring, and toxic control program information. The state provides information on its determination whether the discharge under the proposed conditions of the modified permit ensures the protection of water quality, biological habitats, and beneficial uses of receiving waters and whether the discharge will result in additional treatment, pollution control, or any other requirement for any other point or nonpoint sources. The state also provides information to certify that the discharge will meet all applicable state laws and that the state accepts all permit conditions.
There are four situations where information will be required: 1 A
POTW reapplying for a CWA section 301h modified permit. As the permits with section 301h modifications reach their expiration dates, EPA must have updated information on the discharge to determine whether criteria are still being met and whether the modified permit should be reissued. 2 Once a modified permit has been granted, EPA
must continue to assess whether the discharge is meeting the CWA criteria, and that the receiving water quality, biological habitats, and beneficial uses of the receiving waters are protected. To do this, EPA needs monitoring and toxics control information furnished by the permittee. 3 Application revision information: A POTW is allowed to revise its application one time only,

following a tentative decision by EPA to deny the modified permit request. In its application revision, the POTW usually corrects deficiencies and changes proposed treatment levels as well as outfall and diffuser locations. The application revision is a voluntary submission for the applicant. 4 State determination and state certification information: The state determines whether all state laws are satisfied.
Additionally, the state must determine if the applicants discharge will result in additional treatment, pollution control, or any other requirement for any other point or nonpoint sources. This process allows the states views to be considered when EPA reviews the application and develops permit conditions.
Form numbers: None.
Respondents/affected entities:
Municipalities that currently have CWA
section 301h modifications from secondary treatment, or have applied for a renewal of a CWA section 301h modified permit, and the states within which these municipalities are located.
Respondents obligation to respond:
Required to obtain or retain a benefit.
Estimated number of respondents: 31
total.
Frequency of response: From once every five years, to varies case-by-case, depending on the category of information.
Total estimated burden: 44,985 hours per year. Burden is defined at 5 CFR
1320.3b.
Total estimated cost: $1,300,339 per year, includes $0 annualized capital or operation & maintenance costs.
Changes in the estimates: There is an increase of hours in the total estimated respondent burden compared with the ICR currently approved by OMB. This increase is due to changes in respondent universe, program status, information needs, and use of technology.
