About
Built from inside the work.
NPDESTracker is MS4 compliance software for municipal stormwater programs — small MS4s, larger agencies, and co-permittee programs. It was built around firsthand municipal stormwater compliance workflows at the local level, then turned into a product because the spreadsheets and binders kept getting in the way of the actual job. Phase I and co-permittee reporting structures are scoped during setup using the applicable permit and state agency materials.
Origin
The product started with a stormwater coordinator's problem.
NPDESTracker began as a working answer to a real frustration. MS4 programs spend most of the year doing the work and most of March reconstructing it from spreadsheets, photo folders, email threads, and binders. The annual report is built from memory and copy-paste, and the records that should support it live in five places. None of that is the program's fault. It is what happens when general-purpose tools are asked to do permit-aligned work.
The workflow was designed from firsthand Phase II municipal inspection experience — source control inspections, private stormwater inspections, IDDE field work, FOG (fats, oils, and grease) inspections, GIS and data work, site contacts and follow-up tracking, annual-report evidence support, contractor coordination, and the cross-department conversations that hold an MS4 program together. NPDESTracker is shaped by all of that, not by a marketing exercise.
Specific design choices followed. Inspections capture quickly on a phone, with photos and GPS pinned to the record. IDDE complaints live on a single thread from intake to closure. Annual report counts come from the records logged through the year, not from a fresh blank cell each March. The outline of what NPDESTracker is today came out of writing those workflows down and refusing to let them drift.
The product is focused and serious on purpose. It is built around what MS4 coordinators actually do. The pages on this site describe currently supported workflows. For deeper module walkthroughs or configuration questions, email admin@npdestracker.com.
Operator
Wood Technologies LLC dba NPDESTracker.
NPDESTracker is independently built and operated by Wood Technologies LLC, a small founder-led software shop focused on municipal stormwater compliance. The team does not run a sales queue, support call center, or outsourced helpdesk. Email is the canonical channel; replies come from the NPDESTracker team.
Support is coordinated through admin@npdestracker.com. Procurement, security questionnaires, evaluation workspace inquiries, and configuration questions are all welcome through that channel. Guided kickoff is included on the Guided Evaluation Workspace and on quoted plans where the order form names it.
How we build
The principles the product is built on.
Built from inside the work, not from outside it.
Every workflow in NPDESTracker reflects how the work actually happens at a small or mid-sized Phase II MS4 program. The inspections module is shaped by inspections that happen in the field, not by what an inspection theoretically should look like.
Counts come from records, not invented scores.
Annual report numbers come from the actual records logged through the year. There is no manufactured compliance percentage, no traffic-light theatre, and no fields auto-populated to make a dashboard look complete.
Audit-defensible by default.
Every create, edit, and override leaves a timestamped, user-attributed entry. The product is built on the assumption that a state-agency reviewer will eventually read the audit log, and that everything in it should hold up.
Honest scope.
The site avoids overstating capabilities. Product pages describe supported workflows, and the security page states the current trust posture plainly. Smart Draft is described as assistive and never as a replacement for staff review.
Product, plainly
What NPDESTracker is, in one paragraph.
NPDESTracker is a browser-based compliance documentation tool for municipal MS4 programs. It tracks sites, outfalls, BMPs, drainage structures, inspections, IDDE incidents, complaints, activities, training, and enforcement actions across the six Minimum Control Measures, then assembles the annual report from those records with full audit trails. The first complete annual reporting template wired in is the Western Washington Phase II 2024-2029 template, with adjacent state programs covered in the permit pages.
See the platform overview for what is in the product, the security page for how access and tenancy work, the Smart Draft and AI page for how the optional AI feature is scoped, and pricing for evaluation and annual-platform pricing.
