1. (1) The rules in this chapter apply to any company that is subject to the jurisdiction of the commission as to rates or services under the provisions of RCW 80.01.040 and chapters 80.04 and 80.36 RCW.
2. (2) Tariffs filed by companies must conform to these rules. If the commission accepts a tariff that conflicts with these rules, the acceptance is not a waiver of these rules unless the commission specifically approves the variation consistent with WAC 480-120-015 (Exemptions from rules in chapter 480-120 WAC). Tariffs that conflict with these rules without approval are superseded by these rules.
3. (3) Any affected person may ask the commission to review the interpretation of these rules by a company 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—General).
4. (4) No deviation from these rules is permitted without written authorization by the commission. Violations will be subject to penalties as provided by law.
