Overview

Discharge Monitoring Reports are periodic water pollution reports requiring submittal by regulated entity as a condition of a National Pollution Discharge Emission System (NPDES) permit.  NPDES permitted facilities collect wastewater samples, conduct chemical and/or biological tests of samples and submit reports to the state as a Discharge Monitoring Report.

In order for nVIRO to produce DMRs, NPDES monitoring requirements must be added to a permit. The ability to add monitoring requirements to a permit is configured by permit category.

nVIRO provides sophisticated DMR entry that is generated based upon effluent limits specified in an nVIRO Permit.  Depending upon the agency configuration, users may be required to enter Daily DMR report values or Summary report values. 

Violations are assessed against the permittee for late DMR reporting, or when reported values exceed permit limits.

Determining Whether a DMRs will be Created for a Permit

Foremostly, nVIRO can be configured to never produce Daily or Summary DMRs for any permit. This is controlled by Deployment Setting codes DMR.GEN_DLY and DMR.GEN_SUMM. If set to '0' (off) then Daily or Summary DMRs will never be generated. Deployment settings are managed by Windsor and are configured as part of system setup.

Secondarily, if the “Generate DMRs” checkbox is unchecked on a Limit Set, DMRs will never be produced for that limit set.

Finally, a Daily or Summary DMR will not be produced if none of the parameters in the limit set qualify for inclusion on the DMR. Individual parameters can be configured to display or not on a Daily or Summary DMR. See the following section for more information.

Determining which Parameters appear on Daily and Summary forms

In order for a parameter to appear on a Daily DMR form, The Parameter (under Admin → Lookups → Parameters) must have the “Display on Daily DMR Form” checkbox checked. Furthermore, the Statistical Base Code reference table must indicate that the monitoring requirement’s statistical base code is eligible for display on the daily form. The Statistical Base Code reference table is not manageable via the user interface. The lookup values must be administered by a database administrator

In order for a parameter to appear on a Summary DMR form, The Parameter (under Admin → Lookups → Parameters) must have the “Display on Summary DMR Form” checkbox checked. Furthermore, the Monitoring Location Type code must indicate that the monitoring requirement’s monitoring location is eligible for display on the Summary DMR form. The Monitoring Location Type reference table is not manageable via the user interface. The lookup values must be administered by a database administrator.
