Idaho Phase II

MS4 compliance software for Idaho Phase II permittees.

NPDESTracker is browser-based MS4 software aligned to the six Minimum Control Measures that Phase II permittees in Idaho operate under through the IPDES program. Annual reports that roll up from records, mobile inspections for the field, and a GIS-aware workspace that fits alongside your existing ArcGIS or QGIS deployment.

01 · Aligned to the permit framework

Built around the six Minimum Control Measures.

Idaho's Phase II MS4 permittees operate under the IPDES (Idaho Pollutant Discharge Elimination System) program administered by the Idaho Department of Environmental Quality. The product's data structures and workflows align to the six federal Minimum Control Measures that frame the IPDES Phase II MS4 General Permit, with the annual report template structured the way DEQ expects program-year submissions to read.

MCM 1

Public Education and Outreach

Documented education events, audiences reached, and materials distributed across the reporting year.

MCM 2

Public Involvement and Participation

Public meetings, comment periods, and volunteer programs with attendance and minutes.

MCM 3

Illicit Discharge Detection and Elimination

Complaint intake, dry-weather screening, source tracing, and enforcement on a single thread per outfall.

MCM 4

Construction Site Runoff Control

Active-disturbance inspections, deficiency follow-up, and enforcement records aligned to your construction inspection cadence.

MCM 5

Post-Construction Stormwater Management

Live BMP inventory, annual inspections, and maintenance records for structural BMPs.

MCM 6

Pollution Prevention and Good Housekeeping

Municipal facility inspections, spill response, fleet operations, and staff training tied to MS4 obligations.

02 · Annual reporting

Reporting that holds up under DEQ review.

Every number in your annual MS4 report links back to its underlying record. Counts come from inspections, IDDE incidents, BMP records, and enforcement actions logged through the year, not from free-text fields you reconcile in a spreadsheet at the end of the reporting period.

Manual overrides leave a one-line audit-log entry: user, timestamp, original value, new value, reason. When DEQ reviewers ask "what changed and why," the answer is on screen.

See how reporting works, or read the guide to making an MS4 program audit-ready.

03 · Inspections

Inspections that fit the field, not the office.

Mobile-first inspection workflow built for the inspector in the truck, on phone, tablet, or browser. Photo and GPS attached to each record. Site context one tap away. Cadence-aware so overdue and due-soon items are flagged before they become audit findings.

04 · GIS-aware throughout

Designed to coexist with your existing ArcGIS or QGIS deployment.

Most Idaho Phase II permittees already maintain their authoritative spatial data in ArcGIS Online, ArcGIS Enterprise, or QGIS. NPDESTracker is built to live alongside that, not replace it. Sites, outfalls, BMPs, and incidents live on a map, color-coded by status, with the same coordinates your GIS team already maintains.

Imports standard GIS file formats (GeoJSON, shapefile). CSV exports cover supported operational records, with broader spatial-format export support available during onboarding and support requests. The full interop story is on the GIS workspace page, and there is more on why most programs end up running both in the MS4 software vs ArcGIS post.

05 · How this maps to Idaho programs

The Phase II framework runs the same in Idaho.

NPDESTracker gives municipal stormwater teams a connected workspace for inspections, sites, tasks, enforcement drafts, GIS context, and annual-report evidence. The data model is built around the six federal Minimum Control Measures — the same framework Idaho DEQ uses for the IPDES Phase II MS4 General Permit.

Idaho-specific permit terminology (IPDES naming, reporting cycle, dropdowns, forms) is configured during setup so the workspace reads the way DEQ-issued programs run. Records export as CSV and, where applicable, GeoJSON on every tier — useful when handing evidence to DEQ or to a consulting engineer.

Browser-based MS4 software on phones, tablets, and desktops. Idaho-specific terminology is configured during setup so the workspace matches how IPDES-issued programs are run.
