This training focuses on DMR reporting violations on the quarterly National Pollutant Discharge Elimination System (NPDES) Noncompliance Report (NNCR), which provides a comprehensive list of Clean Water Act violations and their resolutions to the public. It will provide an overview of when DMR reporting violations are generated, criteria for assigning Category I versus II noncompliance, resolution of DMR reporting violations, and a demonstration of searching and filtering DMR reporting violations on the quarterly NNCR. This is an advanced training and assumes you have attended or watched a recording of the quarterly NNCR training before attending.
