STATE FORM REQUIREMENTUSC-NN
Navajo Nation does not mandate a single statewide test form. Most purveyors accept the standard USC/AWWA-style report, which BackflowGo generates — requirements live at the purveyor level.
Navajo Nation (NNEPA primacy): assemblies must be tested annually by an AWWA CA-NV/ABPA-certified tester holding a Navajo PWSSP registration number (NNPDWR §2007) — include your PWSSP number in remarks. Reports go to the system owner/operator, who files annual summaries with NNEPA PWSSP (Window Rock, 928-871-7692); no official form exists.
