National Study of Nutrient Removal and Secondary Technologies: POTW Screener Questionnaire (Renewal)
OMB 2040-0294 · EPA/OW.
OMB 2040-0294
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.
The latest form for National Study of Nutrient Removal and Secondary Technologies: POTW Screener Questionnaire (Renewal) expires 2021-07-31 and is listed under ICR 201910-2040-001.
