The following words and terms, when used in this subchapter, shall
have the following meanings, unless the context clearly indicates otherwise.
(1) Cross-connection--A physical connection between a public
water system and either another supply of unknown or questionable quality,
any source which may contain contaminating or polluting substances, or any
source of water treated to a lesser degree in the treatment process.
(2) Customer service inspection--An examination of the private
water distribution facility for the purpose of providing or denying water
service. The inspection is limited to the identification and prevention of

to believe that cross-connections or other potential contaminant hazards exist,
or after any material improvement, correction, or addition to private water
distribution facilities (see §290.46(j) of this title (relating to Minimum
Acceptable Operating Practices for Public Drinking Water Systems)).
(3) Customer service inspector--The person who is licensed
by the executive director to perform customer service inspections.
