No Discharge on a DMR? Learn if you're putting yourself at risk.
Having an NPDES stormwater permit means having responsibilities, such as doing your regular stormwater sample reporting, usually via a Discharge Monitoring Report (DMR), which can be a very intimidating task. Particularly, now that electronic reporting is a requirement and is being implemented almost everywhere in the US.
The entire DMR process is now confusing, complicated, poorly functioning, full of "codes" and more headaches. So what should you do if you don't get a stormwater sample? If you're tempted to enter "NODI" or "no discharge" on that DMR, you should think twice.
