IDEM Creates New Rule 6 Storm Water Report Form & Establishes eDMR System


By Andy Bowman, Attorney, Bingham Greenebaum Doll LLP

The Office of Water Quality has posted a new state form on its website which must be used by holders of industrial storm water general permits to meet initial and annual monitoring requirements under the industrial storm water rules at 327 IAC 15-6.

The Storm Water Discharge Monitoring Report form must be submitted within one year of filing an initial or renewal Notice of Intent (NOI) letter and 365 days thereafter during the subsequent years two through five. The analytical results of a grab sample collected from each of the outfalls identified in the NOI are entered on the report form along with field information. If the facility monitors its stormwater discharge more frequently than annually or analyses samples for parameters beyond the required parameters, the additional sampling information must be included with the report. The laboratory report and chain of custody form must be attached to the report form. The new report form is available at

The new system, called “eDMR”, is optional and does not require payment of a fee. To use eDMR, the permit holder’s data entry person, authorized representative and certified operator must each register to use the system on forms available at
