WAC 480-75-200   Application of rules -- Responsibility for contractors.   (1) The rules in this chapter apply to hazardous liquid pipeline companies that are subject to the jurisdiction of the commission under chapter 81.88 RCW. The purpose of ((the)) these rules is to provide minimum safety standards and reporting requirements for the transportation of hazardous liquids by pipeline, and to set forth a regulatory fee methodology that applies to all pipeline companies subject to inspection by the commission.

(2) While the commission's hazardous liquid pipeline safety statutes and rules impose obligations on pipeline companies, a pipeline company may contract with a person to do tasks that are subject to these rules, such as excavation, construction, and maintenance. If the pipeline company's contractor (or any of its subcontractors) engages in conduct that violates commission rules applicable to the pipeline company, the pipeline company is subject to penalties and all other applicable remedies, as if the pipeline company itself engaged in that conduct, including intentional noncompliance or other intentional violations of these rules by the contractor (or any of its subcontractors). The pipeline company is responsible for maintaining measures designed to detect intentional violations of these rules by a contractor and any of its subcontractors.

[Statutory Authority: RCW 80.01.040 and 80.04.160. 02-18-032 (Docket No. TO-000712, General Order No. R-500), 480-75-200, filed 8/26/02, effective 9/26/02.]


AMENDATORY SECTION(Amending Docket No. TO-000712, General Order No. R-500, filed 8/26/02, effective 9/26/02)

WAC 480-75-210   Additional requirements.   (1) These rules do not relieve any pipeline company from any of its duties and obligations under the laws of the state of Washington.

(2) The commission retains the authority to impose additional or different requirements on any company in appropriate circumstances, consistent with the requirements of law.

[Statutory Authority: RCW 80.01.040 and 80.04.160. 02-18-032 (Docket No. TO-000712, General Order No. R-500), 480-75-210, filed 8/26/02, effective 9/26/02.]


AMENDATORY SECTION(Amending Docket No. P-041344, General Order No. R-523, filed 8/4/05, effective 7/1/06)

WAC 480-75-240   Annual pipeline safety fee methodology.   (1) ((Every hazardous liquid pipeline company subject to inspection or enforcement by the commission)) This rule sets forth the commission's regulatory fee methodology for hazardous liquid pipelines as that term is defined in RCW 81.88.010, and gas pipelines, as that term is defined in RCW 81.88.010. For purposes of this section, these pipelines are called "company" or "companies" and the "commission's pipeline safety program" means the pipeline safety program that includes each program.

(2) Each company will pay an annual pipeline safety fee as established in the methodology set forth in ((section (2) below)) subsection (3) of this section.

(((2))) (3) The fee will be set by general order of the commission entered before ((July)) September 1 of each year and will be collected in four equal installments payable on the first day of each ((calendar)) quarter as listed below:

1st quarter fee installment due September 1;

2nd quarter fee installment due December 1;

3rd quarter fee installment due March 1;

4th quarter fee installment due June 1.

(a) The total of pipeline safety fees will be calculated to recover no more than the costs of the legislatively authorized workload represented by current appropriations for the commission's pipeline safety program, less the amount received in total base grants through the Federal Department of Transportation and less any amount received from penalties collected under RCW 19.122.050. Federal grants, other than the federal base grant, received by the commission for additional activities not included or anticipated in the legislatively directed workload will not be credited against pipeline company ((pipeline)) safety fees, nor will the work supported by ((such)) grants be considered a cost for purposes of calculating ((such)) fees. To the extent that the actual base grant proceeds are different than the amount credited, the difference will be applied in the following year.

(b) Total pipeline safety fees as determined in (a) of this subsection will be calculated in two parts:

(i) The commission's annual overhead charge to the pipeline safety program will be allocated among companies according to each company's share of the total of all pipeline miles within Washington as reported by ((the)) companies in their annual reports to the commission.

(ii) After deducting the commission's annual overhead charge, the remainder of the total pipeline safety fees will be allocated among companies in proportion to each company's share of the commission pipeline safety program staff hours that are directly attributable to particular companies. The commission will determine each company's share by dividing the total hours directly attributable to ((the)) each company during the two preceding calendar years (as reflected in the program's timekeeping system) by the total of directly attributable hours for all companies over the same period.

(iii) For fee-setting purposes, any program hours related to a ((staff)) commission investigation of an incident found to be attributed to third-party damage ((resulting)) that results in penalties collected under RCW 19.122.055 will not be directly attributed to the ((operator)) owner of the damaged pipeline ((for fee-setting purposes)).

(c) The commission general order setting fees pursuant to this rule will detail the specific calculation of each company's pipeline safety fee including the allocations set forth in (b) of this subsection.

(((3))) (4) By ((June)) August 1 of each year the commission ((staff)) will mail an invoice to each company ((an invoice)).

(((4))) (5) All funds received by the commission for the pipeline safety program will be deposited to the pipeline safety account. For ((those companies)) each gas pipeline company subject to RCW 81.24.010 ((the)), its portion of the company's total regulatory fee applicable to pipeline safety will be transferred from the public service revolving fund to the pipeline safety account.

(((5))) (6) Any company wishing to contest the amount of the fee imposed under this section must pay the fee when due and, within ((6)) six months ((of)) after the due date of the fee, file a written petition ((in writing)) with the commission requesting a refund. The petition shall state the name of the petitioner; the date and the amount paid, including a copy of any receipt, if available; the amount of the fee that is contested; ((and any)) all reasons why the commission ((may)) should not impose the fee in that amount; and a calculation and explanation of the fee amount the petitioner contends is appropriate, if any. The commission may grant the petition administratively or may set the petition for adjudication ((or for brief adjudication)).

WAC 480-75-250   Civil penalty for violation of chapter 81.88 RCW.   (((1))) Any pipeline company that violates any ((public)) pipeline safety provision of any commission order or any rule in this chapter including those rules adopted by reference, or chapter 81.88 RCW ((or regulation issued thereunder, required for compliance with the Federal Pipeline Safety Law, 49 U.S.C. Section 60101,)) is subject to a civil penalty not to exceed ((twenty-five)) one hundred thousand dollars for each violation for each day that the violation persists. The maximum civil penalty under this subsection for a related series of violations is ((five hundred thousand)) one million dollars.

(2) To request a rule exemption, a person must file with the commission a written request identifying the rule for which an exemption is sought, giving a full explanation of the reason for the exemption.

(3) The commission will assign the request a docket number, if it does not arise in an existing docket, and will schedule the request for consideration at one of its regularly scheduled open meetings or, if appropriate under chapter 34.05 RCW, in an adjudication. The commission will notify the person requesting the exemption, and other interested persons, of the date of the hearing or open meeting when the commission will consider the request.

(4) In determining whether to grant the request, the commission may consider whether application of the rule would impose undue hardship on the petitioner, of a degree or a kind different from hardship imposed on other similarly situated persons, and whether the effect of applying the rule would be contrary to the purpose of the rule.

(5) The commission will enter an order granting or denying the request, or setting it for hearing pursuant to chapter 480-07 WAC)) pursuant to WAC 480-07-110. Please refer to that rule for applicable procedures.
