(1) The rules in this chapter apply to any electric utility that is subject to the jurisdiction of the commission under RCW 80.04.010 and chapter 80.28 RCW. These rules also include various requirements of the utility's customers and applicants.

Tariffs that conflict with these rules without approval are superseded by these rules.

(3) Any affected person may ask the commission to review the interpretation of these rules by a utility or customer by posing an informal complaint under WAC 480-07-910, Informal complaints, or by filing a formal complaint under WAC 480-07-370, Pleading and briefs—Application for authority—Protests.
