# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Notice.

# SUMMARY:

                        The Environmental Protection Agency (EPA) has submitted an information collection request (ICR), National Study of Nutrient Removal and Secondary Technologies: Publicly Owned Treatment Works (POTW) Screener Questionnaire (EPA ICR Number 2553.03, OMB Control Number 2040-0294) to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act. This is a proposed extension of the ICR, which is currently approved through July 31, 2021. Public comments were previously requested via the                         **Federal Register**                         on February 24, 2021 during a 60-day comment period. No comments were received. This notice allows for an additional 30 days for public comments. A fuller description of the ICR is given below, including its estimated burden and cost to the public.

*Abstract:*                     Nutrient pollution remains the single greatest challenge to our Nation's water quality and presents a growing threat to public health and local economies—contributing to toxic harmful algal blooms, contamination of drinking water sources, and costly impacts on recreation, tourism and fisheries. The National Study of Nutrient Removal and Secondary Technologies, when completed, will provide a rich database of nutrient removal performance at secondary treatment POTWs nationwide, and will help POTWs understand the range of nutrient removal performance and identify opportunities to optimize nutrient removals based on data from their peers. It will also serve as a major new resource for stakeholders to evaluate the most cost-effective approaches to nutrient reduction at the watershed scale. EPA's Office of Water is collecting data to evaluate the nutrient removals and related technology performance of POTWs with conventional secondary treatment. Due to multiple delays, most notably postponements in fielding the screener questionnaire due to circumstances associated with the coronavirus (COVID-19) pandemic, EPA is proposing to renew the ICR for the screener questionnaire.                

The screener questionnaire is a one-time data collection that solicits basic facility identification, characterization, and technical information necessary to develop the future detailed questionnaire. Questions include those necessary to identify and stratify the universe of POTWs and, within that population, the secondary treatment POTWs not designed specifically to remove nitrogen and phosphorus. EPA would prepare a separate ICR for subsequent phases of the study.

                    In this renewal EPA proposes three revisions to the currently approved screener questionnaire ICR and supporting statement. First, EPA has reduced the maximum number of respondents from 16,500 to 15,000 reflecting survey responses already received as of October 30, 2020. Second, EPA has made minor clarifying edits to the survey questions such as providing additional examples of certain technology classifications. Third, EPA is revising the respondent burden estimates. The original average burden estimate assumed it would take one hour to complete the registration process and three hours to complete the full questionnaire. EPA reviewed start and end times associated with questionnaires submitted online and found that the average time to complete the long version of the online questionnaire was 1.1 hours and the time to complete the short version was 26 minutes. EPA revised the average burden to 2.25 hours for the questionnaire and 15 minutes for registration (Questionnaire Section A) based on this information. EPA solicits comment on these proposed changes. A copy of the screener questionnaire is available at Docket ID No. EPA-HQ-                          ( print page 40563)                        OW-2016-0404 as part of this request for comments.                

*Form Numbers:*                     None.                

*Respondents/affected entities:*                     Approximately 15,000 POTWs that meet the definition under 40 CFR 403.3(q), 50 POTWs for site visits, and 100 state and/or small municipal association contacts.                

*Respondent's obligation to respond:*                     Voluntary.                

*Estimated number of respondents:*                     12,000 (total).                

*Frequency of response:*                     One-time data collection.                

*Total estimated burden:*                     8,747 hours (per year). Burden is defined at 5 CFR 1320.03(b).                

*Total estimated cost:*                     $398,120 (per year), which includes $8,800 annualized capital or operation & maintenance costs.                

*Changes in Estimates:*                     There is decrease of approximately 41,000 hours in the total estimated respondent burden compared with the ICR currently approved by OMB. This decrease is due to screener questionnaire responses already received, reduced number of total respondents, and replacement of EPA's estimated respondent burdens with the actual time respondents took to complete the screener questionnaire.
