Discharge MonitoringReport(eD ) internet applicatvon.
�� \ 2L as
Monitoring results obtained duffing the previous month(s) shall be summarized for each month and
submitted electro c`allyai sing eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submi�DMRs�electronically using the internet. Until such time that the state's
eDMR applicat on is compliant witl%EPA's Cross-Media Electronic Reporting Regulation
(CROMERR), p rcmittees will be required to submit all discharge monitoring data to the state
