Tennessee rules behind the local programs

State rules set the minimum; the utilities above add their own deadlines and tester registration.

Tennessee's rule (0400-45-01-.17(6)) sets no test interval. TDEC's Cross-Connection Control Manual, which is guidance, says assemblies should be tested at least every 12 months, and each water system enforces its own program.
TDEC Division of Water Supply criteria in the manual tell water purveyors to see that assemblies are tested after installation and at least annually.
The TDEC manual states it is guidance only and does not create legal rights or obligations; binding force comes from the rule plus each system's approved ordinance.
