EPA’s National Study of Nutrient Removal & Secondary Technologies is designed to establish a nationwide baseline for nutrient removal at publicly owned treatment works (POTWs) and to characterize low-cost options such as operation and management practices that result in improved nutrient control.  EPA recently published a Federal Register notice (September 19, 2016) on the proposed initial phase of the study which will collect basic information from all POTWs nationwide through a mandatory questionnaire.  Last week, EPA announced two webinars intended to provide background on the study and the agency will specifically focus on demonstrating the content and electronic format of the draft questionnaire on November 2, 2016 and November 10, 2016 (link).
