PDF480-75-200

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 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, 80.04.060, 81.88.040. WSR 08-12-045 (Docket PL-070974, General Order R-548), § 480-75-200, filed 5/30/08, effective 6/30/08. Statutory Authority: RCW 80.01.040 and 80.04.160. WSR 02-18-032 (Docket No. TO-000712, General Order No. R-500), § 480-75-200, filed 8/26/02, effective 9/26/02.]


PDF480-75-210

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, 80.04.060, 81.88.040. WSR 08-12-045 (Docket PL-070974, General Order R-548), § 480-75-210, filed 5/30/08, effective 6/30/08. Statutory Authority: RCW 80.01.040 and 80.04.160. WSR 02-18-032 (Docket No. TO-000712, General Order No. R-500), § 480-75-210, filed 8/26/02, effective 9/26/02.]


PDF480-75-220

Severability.

If any provision of this chapter or its application to any person or circumstance is held invalid, the remainder of the chapter or the application of the provision to other persons or circumstances is not affected.
[Statutory Authority: RCW 80.01.040 and 80.04.160. WSR 02-18-032 (Docket No. TO-000712, General Order No. R-500), § 480-75-220, filed 8/26/02, effective 9/26/02.]


PDF480-75-240

Annual pipeline safety fee methodology.

(1) 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 subsection (3) of this section.
(3) The fee will be set by general order of the commission entered before September 1 of each year and will be collected in four equal installments payable on the first day of each 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. 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 safety fees, nor will the work supported by grants be considered a cost for purposes of calculating 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 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 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 commission investigation of an incident found to be attributed to third-party damage that results in penalties collected under RCW 19.122.055 will not be directly attributed to the owner of the damaged pipeline.
(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.
(4) By August 1 of each year the commission will mail an invoice to each company.
(5) All funds received by the commission for the pipeline safety program will be deposited to the pipeline safety account. For each gas pipeline company subject to RCW 81.24.010, 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.
(6) Any company wishing to contest the amount of the fee imposed under this section must pay the fee when due and, within six months after the due date of the fee, file a written petition 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; all reasons why the commission 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.

Damage prevention.

Each pipeline company must comply with the provisions of chapter 19.122 RCW, to the extent those provisions apply to the pipeline company. A pipeline company violates this rule if the pipeline company fails to comply with chapter 19.122 RCW. Each day a violation persists is a separate violation of this rule. In determining whether a pipeline company has complied with the provisions of chapter 19.122 RCW, the definitions contained in that chapter will apply. The definitions in chapter 480-75 WAC (other than the definition of "hazardous liquid pipeline company") do not apply.

Backfill and bed requirements.

(1) When a pipeline company constructs a new pipeline or conducts maintenance on an existing pipeline, the backfill and bed must provide firm support for the pipeline such that neither the pipe nor the pipe coating is damaged by the backfill material or by subsequent surface activities.
(2) If the backfill material contains rocks or hard lumps that could damage the pipeline coating, the pipeline company must take care to protect the pipe and the pipe coating from damage, such as using mechanical shield material.
(3) A pipeline company's backfill practices must not cause distortion of the pipe cross-section that would be detrimental to the operation of the piping, or the passage of cleaning devices, internal inspection devices, or other similar devices.
(4) A pipeline company must apply backfill material in such a manner as to prevent excessive subsidence or erosion of the backfill and support material. Where a ditch is flooded, the pipeline company must assure that the pipe is not floated from the bottom of the ditch prior to completing the backfill.
(5) For open trench installations that cross paved areas subject to vehicular loading, the pipeline company must compact the backfill in layers to a minimum of ninety-five percent relative density.
(6) The bedding and backfill material a pipeline company uses must consist of clean sand or soil and it must not contain any stones larger than one-half inch. The pipeline company must place the bedding and backfill material at a minimum depth of six inches under the pipe and six inches over the top of the pipe. The remaining backfill must not contain rock larger than six inches. The pipeline company shall not use organic material or wood for bedding or backfill.

Hydrostatic test requirements.

The following minimum requirements apply to a pipeline company when it conducts a hydrostatic test of a new or existing pipeline:
(1) If a pipeline company uses a manifold for hydrostatic testing, the company must provide an isolation valve between the pressure testing manifold and the pipeline being tested. The isolation valve must be rated for the manifold test pressure when in the closed position. The pipeline company must separately pressure test the manifold used in the actual pressure test to at least 1.2 times the pipeline test pressure, but not less than the discharge pressure of the pump used for the pressure testing.
(2) If a pipeline company uses a pressure relief valve to protect the pipe, each such valve must be of adequate capacity and set to relieve at ten percent above the hydrostatic test pressure. The pipeline company must calibrate the relief valve within one month prior to the hydrostatic test.
(3) The pipeline company may use a bleed valve to protect the pipeline from overpressure. When a pipeline company uses a bleed valve, the valve must be readily accessible in case immediate depressurization is required.
(4) All equipment such as hoses, piping, and other equipment used to hydrostatically test the pipe must be rated for at least the target pressure.
(5) The pipeline company must maintain documents identifying how each hydrostatic test was conducted. Each document must be signed by a person with sufficient knowledge, certifying that the document contains accurate information about the test. The documents must contain the following information:
(a) The date of the test;
(b) A test chart or other record that shows that the pressure was maintained at the minimum test pressure throughout the entire test;
(c) Beginning and ending times of the test;
(d) Beginning and ending temperatures; and
(e) Highest and lowest pressure achieved.
(6) The pipeline company must conspicuously post precautions such as warning signs indicating that a hazardous liquid pipeline is under test conditions.
(7) The pipeline company must notify the local government and fire department with jurisdiction in the area affected by the hydrostatic test.
(8) The pipeline company shall not add any water to the pipeline after the hydrostatic test has started. Because pressure varies significantly with changing test water temperatures, each pipeline company must take into consideration temperature variations in the test water before accepting the test results.
(9) The pipeline company must comply with applicable rules of the Washington state department of ecology addressing disposal of testing water.
