(1)(a) Complaint may be made by the commission of its own motion or by any person or corporation, chamber of commerce, board of trade, or any commercial, mercantile, agricultural or manufacturing society, or any body politic or municipal corporation, or by the public counsel section of the office of the attorney general, or its successor, by petition or complaint in writing, setting forth any act or thing done or omitted to be done by any public service corporation in violation, or claimed to be in violation, of any provision of this title, Title
81 RCW, or of any order or rule of the commission.
(b) No complaint may be entertained by the commission except upon its own motion, as to the reasonableness of the schedule of the rates or charges of any gas company, electrical company, water company, wastewater company, or telecommunications company, unless the same be signed by the mayor, council or commission of the city or town in which the company complained of is engaged in business, or not less than twenty-five consumers or purchasers of such gas, electricity, water, wastewater company services, or telecommunications service, or at least twenty-five percent of the consumers or purchasers of the company's service.
(c) When two or more public service corporations, (meaning to exclude municipal and other public corporations) are engaged in competition in any locality or localities in the state, either may make complaint against the other or others that the rates, charges, rules, regulations or practices of such other or others with or in respect to which the complainant is in competition, are unreasonable, unremunerative, discriminatory, illegal, unfair or intending or tending to oppress the complainant, to stifle competition, or to create or encourage the creation of monopoly, and upon such complaint or upon complaint of the commission upon its own motion, the commission has power, after notice and hearing as in other cases, to, by its order, subject to appeal as in other cases, correct the abuse complained of by establishing such uniform rates, charges, rules, regulations or practices in lieu of those complained of, to be observed by all of such competing public service corporations in the locality or localities specified as is found reasonable, remunerative, nondiscriminatory, legal, and fair or tending to prevent oppression or monopoly or to encourage competition, and upon any such hearing it is proper for the commission to take into consideration the rates, charges, rules, regulations and practices of the public service corporation or corporations complained of in any other locality or localities in the state.
(2) All matters upon which complaint may be founded may be joined in one hearing, and no motion may be entertained against a complaint for misjoinder of complaints or grievances or misjoinder of parties; and in any review of the courts of orders of the commission the same rule shall apply and pertain with regard to the joinder of complaints and parties as herein provided. However, all grievances to be inquired into must be plainly set forth in the complaint. No complaint may be dismissed because of the absence of direct damage to the complainant.
(3) Upon the filing of a complaint, the commission shall cause a copy thereof to be served upon the person or corporation complained of, which must be accompanied by a notice fixing the time when and place where a hearing will be had upon such complaint. The time fixed for such hearing may not be less than ten days after the date of the service of such notice and complaint, excepting as herein provided. The commission shall enter its final order with respect to a complaint filed by any entity or person other than the commission within ten months from the date of filing of the complaint, unless the date is extended for cause. Rules of practice and procedure not otherwise provided for in this title may be prescribed by the commission. Such rules may include the requirement that a complainant use informal processes before filing a formal complaint.
(4)(a) The commission may, as appropriate, audit a nonmunicipal water system upon receipt of an administrative order from the department, or the city or county in which the water system is located, finding that the water delivered by a system does not meet state board of health standards adopted under RCW
43.20.050(2)(a) or standards adopted under chapters
70A.100 and
70A.125 RCW, and the results of the audit must be provided to the requesting department, city, or county. However, the number of nonmunicipal water systems referred to the commission in any one calendar year shall not exceed twenty percent of the water companies subject to commission regulation as defined in RCW
80.04.010.
(b) Every nonmunicipal water system referred to the commission for audit under this section shall pay to the commission an audit fee in an amount, based on the system's twelve-month audited period, equal to the fee required to be paid by regulated companies under RCW
80.24.010.
(5) Any customer or purchaser of service from a water system or company that is subject to commission regulation may file a complaint with the commission if he or she has reason to believe that the water delivered by the system to the customer does not meet state drinking water standards under chapter
43.20 or
70A.100 RCW. The commission shall investigate such a complaint, and shall request that the state department of health or local health department of the county in which the system is located test the water for compliance with state drinking water standards, and provide the results of such testing to the commission. The commission may decide not to investigate the complaint if it determines that the complaint has been filed in bad faith, or for the purpose of harassment of the water system or company, or for other reasons has no substantial merit. The water system or company shall bear the expense for the testing. After the commission has received the complaint from the customer and during the pendency of the commission investigation, the water system or company may not take any steps to terminate service to the customer or to collect any amounts alleged to be owed to the company by the customer. The commission may issue an order or take any other action to ensure that no such steps are taken by the system or company. The customer may, at the customer's option and expense, obtain a water quality test by a licensed or otherwise qualified water testing laboratory, of the water delivered to the customer by the water system or company, and provide the results of such a test to the commission. If the commission determines that the water does not meet state drinking water standards, it shall exercise its authority over the system or company as provided in this title, and may, where appropriate, order a refund to the customer on a pro rata basis for the substandard water delivered to the customer, and shall order reimbursement to the customer for the cost incurred by the customer, if any, in obtaining a water quality test.
