This study will collect nationwide data on nutrient pollutant removal from publicly owned treatment works (POTWs) with conventional secondary treatment. The data will help set realistic and achievable nutrient reduction targets; help POTW operators understand the range of opportunities to optimize nutrient removals based on data from their peers; and encourage improved nutrient removal performance at POTWs with less expense. The full study is designed with multiple phases over the course of four to five years. The first phase of the study is a screener questionnaire, to collect basic information and characterize the full population of POTWs. This information will help establish a baseline of nutrient performance at the national level for all POTWs.
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.
