Arkansas requires the NetDMR electronic format.  Click here for more information on setting up the NetDMR in WIMS.

From https://www.adeq.state.ar.us/water/enforcement/compliance/netdmr.aspx:
Beginning December 21, 2016, Arkansas NPDES permittees are required to submit discharge monitoring reports (DMRs) electronically using the web-based tool NetDMR.

See Arkansas-dmr-manual.pdf for instructions on DMR reporting and calculations for Arkansas, from March 23,2009.

Prior to the NetDMR Arkansas utilized the NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) DMR Report format.  Click here for the NPDES report templates.
