What does eDMR stand for?

• A. Electronic data management system
• B. Electronic discharge monitoring system
• C. Electronic document monitoring regulation
• D. Environmental discharge monitoring resource

Answer: (B)

The key idea is the meaning of the acronym eDMR in the Clean Water Act context. eDMR stands for Electronic Discharge Monitoring Report—the electronic version of the discharge monitoring report used to document and submit effluent monitoring data required by NPDES permits. This electronic submission streamlines data accuracy, timeliness, and recordkeeping for regulatory agencies and permittees. The other options don’t fit how the term is used in practice: they either describe generic data management, a nonstandard regulation name, or an unrelated resource, rather than the specific report that communicates monitoring results.
