13.28.080 Cross-Connection Hazard Assessments
-191-
In accordance with the CCCPH, the following events require a Cross-Connection Control Specialist complete a hazard assessment and submit to the Hillsborough’s Cross-Connection Control Coordinator for approval:
a) if a user premises changes account holder, excluding single-family residences; b) if a user premises is newly or re-connected to the Town’s potable water system; c) if evidence exists of changes in the activities or materials on a user’s premises; d) if backflow from a user’s premises occurs;
e) periodically, as identified in the Hillsborough’s Cross-Connection Control Plan required pursuant to CCCPH section 3.1.4
f) if the State Water Board requests a hazard assessment of a user’s premises; and g) if the Town concludes an existing hazard assessment may no longer accurately represent the degree of hazard.
Hillsborough’s cross-connection control specialist must review or conduct each initial and follow-up hazard assessment pursuant to this section and make a written finding that, in the specialist’s judgment based on crossconnection control principles, the hazard assessment properly identified all hazards at the time of the assessment, the appropriate degree of hazards, and the corresponding backflow protection.
13.28.090 Interpretation of this Chapter.
In interpreting the intent or requirements associated with this Chapter, the Town of Hillsborough’s Cross Control Prevention Plan shall be used to provide guidance, as reasonably determined by the Town.
