WAC 480-93-18601   Leak classification and action criteria -- Grade -- Definition -- Priority of leak repair.   (1) A "Grade 1 leak" is a leak that represents an existing or probable hazard to persons or property and requiring prompt action, immediate repair, or continuous action until the conditions are no longer hazardous.

     (a) Prompt action in response to a Grade 1 leak may require one or more of the following:

     (i) Implementation of the ((operator's)) gas pipeline company's emergency plan pursuant 49 CFR § 192.615;

     (ii) Evacuating the premises;

     (iii) Blocking off an area;

     (iv) Rerouting traffic;

     (v) Eliminating sources of ignition;

     (vi) Venting the area;

     (vii) Stopping the flow of gas by closing valves or other means; or

     (viii) Notifying police and fire departments.

     (b) Examples. Grade 1 leaks requiring prompt action include, but are not limited to:

     (i) Any leak, which in the judgment of ((operating)) gas pipeline company personnel at the scene, is regarded as an immediate hazard;

     (ii) Escaping gas that has ignited unintentionally;

     (iii) Any indication of gas that has migrated into or under a building or tunnel;

     (iv) Any reading at the outside wall of a building or where the gas could potentially migrate to the outside wall of a building;

     (v) Any reading of eighty percent LEL or greater in an enclosed space;

     (vi) Any reading of eighty percent LEL, or greater in small substructures not associated with gas facilities where the gas could potentially migrate to the outside wall of a building; or

     (vii) Any leak that can be seen, heard, or felt and which is in a location that may endanger the general public or property.

     (2) A "Grade 2 leak" is a leak that is recognized as being not hazardous at the time of detection but justifies scheduled repair based on the potential for creating a future hazard.

     (a) ((Operators)) Each gas pipeline company must repair or clear Grade 2 leaks within fifteen months from the date the leak is reported. If a Grade 2 leak occurs in a segment of pipeline that is under consideration for replacement, an additional six months may be added to the fifteen months maximum time for repair provided above. In determining the repair priority, ((operators)) each gas pipeline company should consider the following criteria:

     (i) Amount and migration of gas;

     (ii) Proximity of gas to buildings and subsurface structures;

     (iii) Extent of pavement; and

     (iv) Soil type and conditions, such as frost cap, moisture and natural venting.

     (b) ((Operators)) Each gas pipeline company must reevaluate Grade 2 leaks at least once every six months until cleared. The frequency of reevaluation should be determined by the location and magnitude of the leakage condition.

     (c) Grade 2 leaks vary greatly in degree of potential hazard. Some Grade 2 leaks, when evaluated by the criteria, will require prompt scheduled repair within the next five working days. Other Grade 2 leaks may require repair within thirty days. The ((operator)) gas pipeline company must bring these situations to the attention of the individual responsible for scheduling leakage repair at the end of the working day. Many Grade 2 leaks, because of their location and magnitude, can be scheduled for repair on a normal routine basis with periodic reevaluation as necessary.

     (d) When evaluating Grade 2 leaks, ((operators)) each gas pipeline company should consider leaks requiring action ahead of ground freezing or other adverse changes in venting conditions, and any leak that could potentially migrate to the outside wall of a building, under frozen or other adverse soil conditions.

     (e) Examples. Grade 2 leaks requiring action within six months include, but are not limited to:

     (i) Any reading of forty percent LEL or greater under a sidewalk in a wall-to-wall paved area that does not qualify as a Grade 1 leak and where gas could potentially migrate to the outside wall of a building;

     (ii) Any reading of one hundred percent LEL or greater under a street in a wall-to-wall paved area that does not qualify as a Grade 1 leak and where gas could potentially migrate to the outside wall of a building;

     (iii) Any reading less than eighty percent LEL in small substructures not associated with gas facilities and where gas could potentially migrate creating a probable future hazard;

     (iv) Any reading between twenty percent LEL and eighty percent LEL in an enclosed space;

     (v) Any reading on a pipeline operating at thirty percent of the specified minimum yield strength or greater in Class 3 or 4 locations that does not qualify as a Grade 1 leak; or

     (vi) Any leak that in the judgment of ((operating)) gas pipeline company personnel at the scene is of sufficient magnitude to justify scheduled repair.

     (3) A "Grade 3 leak" is a leak that is not hazardous at the time of detection and can reasonably be expected to remain not hazardous.

     (a) ((Operators)) Each gas pipeline company should reevaluate Grade 3 leaks during the next scheduled survey, or within fifteen months of the reporting date, whichever occurs first, until the leak is regraded or no longer results in a reading.

     (b) Examples. Grade 3 leaks requiring reevaluation at periodic intervals include, but are not limited to:

     (i) Any reading of less than eighty percent LEL in small gas associated substructures, such as small meter boxes or gas valve boxes; or

     (ii) Any reading under a street in areas without wall-to-wall paving where it is unlikely the gas could migrate to the outside wall of a building.

WAC 480-93-240   Annual pipeline safety fee methodology.   (1) ((Every gas company and every interstate gas pipeline company subject to inspection or enforcement by the commission)) This rule sets forth the commission's fee methodology for the annual regulatory fee paid by a gas pipeline company as that term is defined in RCW 81.88.010. For the purposes of this section, a gas pipeline company is called "company" or "companies" and the "commission's pipeline safety program" means the pipeline safety program that includes each company.

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

     (((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 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 gas pipeline 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 fee commission's annual pipeline safety program allotment will be allocated among companies in proportion to each company's share of the 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 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 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 gas 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 80.24.010, ((the)) their 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 months ((of)) after the due date of the fee, file a petition in writing with the commission requesting a refund. The petition must 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 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.
