Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The primary purpose of the supplemental CR-102 is to clarify the intent of the proposed effective dates in WAC 480-93-100(5) and 480-93-188(3) and to change the definition of "business district." Comments received from stakeholders after the proposed rules were published on June 30, 2004, indicate that language concerning the effective dates of these two rules was not clear. In addition, the supplemental CR-102 provides minor clarifying changes to various rules in chapter 480-93 WAC. A more detailed description of the substantive changes to the proposed rules is set forth below.

NOTE: This summarizes, by rule, the substantive changes now being proposed to the proposed rules in chapter 480-93 WAC that were published at WSR 04-15-141:

WAC 480-93-005: The supplemental proposal would modify the proposed rule by changing the definition of the term "business district" and changes the term "building of public assembly" to "high occupancy structure or area."

WAC 480-93-015: Clarifies the language pertaining to calibration of instruments used for leak surveying.

WAC 480-93-020: Subsections (1)(a)(ii) and (b)(ii) are redrafted to reflect the change in definition from "building of public assembly" to "high occupancy structure or area" and rewritten for clarity.

WAC 480-93-080: Subsection (2)(c) is redrafted to clarify the tracking of production fuses.

WAC 480-93-100: Subsection (5) is modified to clarify the intent to require compliance with the rule after a one-year phase-in period.

WAC 480-93-110: Subsection (1) of the original proposal is duplicative of requirements in C.F.R. 49 Part 192, and has been deleted. The commission has determined that the provisions of subsection (7) of the original proposal are no longer necessary and the section has also been deleted.

WAC 480-93-160: Clarifies that certain reports must be filed with the commission.

WAC 480-93-188: Subsection (7) is modified to clarify the intent to require compliance with the rule after a two-year phase-in period.

Reasons Supporting Proposal: The proposed rules are necessary and reasonable to ensure the safety of gas pipeline operations and to promote safety for the citizens of Washington state from the hazards of gas pipeline operations. In addition, a review of the existing rules and the commission's experience in inspecting pipeline facilities in the state has shown a need for clarification of rules, consistency in practices among companies, and definition of terms used in federal and state rules. Some of the proposed rules apply more stringent requirements than existing federal rules to address concerns the commission has identified in its experience in inspecting pipeline facilities.

Statutory Authority for Adoption: RCW 80.01.040, 80.04.160, and 80.28.210.

Statute Being Implemented: Not applicable.

Rule is not necessitated by federal law, federal or state court decision.

Name of Proponent: Washington Utilities and Transportation Commission, governmental.

Name of Agency Personnel Responsible for Drafting: Sondra Walsh, Senior Policy Strategist, 1300 South Evergreen Park Drive S.W., Olympia, WA 98504, (360) 664-1286; Implementation and Enforcement: Carole J. Washburn, Executive Secretary, 1300 South Evergreen Park Drive S.W., Olympia, WA 98504, (360) 664-1174.

A small business economic impact statement has been prepared under chapter 19.85 RCW.

Small Business Economic Impact Statement

A copy of the small business economic impact statement (SBEIS) was shown in the CR-102 filed as WSR 04-15-141. No changes contained in the proposal in this supplemental CR-102 would alter the result of the earlier SBEIS.

AMENDATORY SECTION(Amending Order R-103, filed 5/18/77)

WAC 480-93-186   Leakage classification and action criteria.   (((1) Gas leak classification and repair.

(a) General. Each gas company shall establish a procedure by which leakage indications of flammable gas will be graded and controlled. When evaluating any leak indication a preliminary step is to determine the perimeter of the leak area. When this perimeter extends to a building wall the investigation shall extend inside the building.

(b) Leak grades. Based on an evaluation of the location and/or magnitude of a leak, one of the following leak grades shall be assigned, thereby establishing the leak repair priority. A gas company may utilize an alphabetical grade classification, i.e. Grade A for Grade 1, Grade B for Grade 2, and Grade C for Grade 3 if it has historically utilized such a grading designation.

Grade 1 - Grade 1 means a leak that represents an existing or probable hazard to persons or property and requiring immediate repair or continuous action until conditions are no longer hazardous.

Grade 2 - Grade 2 means a leak recognized as being nonhazardous at the time of detection but requiring scheduled repair based on probable future hazard.

Grade 3 - Grade 3 means a leak that is nonhazardous at the time of detection and can reasonably be expected to remain nonhazardous.

Leakage classification and control requirements are provided in Table 1. The examples of leakage provided in the table are guidelines and are not exclusive. The judgment of the gas company personnel at the scene is of primary importance in determining the grade assigned to a leak.

(c) Follow-up inspections. The adequacy of leak repairs shall be checked by acceptable methods while the excavation is open. The perimeter of the leak area shall be checked with a CGI. In the case of repair of a Grade 1 leak, where there is residual gas in the ground, a follow-up inspection shall be made as soon as practical but in no case later than one month following the repair. In the case of Grade 2 or Grade 3 leaks which have been repaired, the need for a follow-up inspection shall be determined by qualified personnel employed or retained by the gas company.

(2) Regrading of leaks. Leaks are to be reinspected using the same criteria used to grade leaks when they are first detected and graded.)) (1) Based on an evaluation of the location and/or magnitude of a leak, the operator must assign one of the leak grades in subsection (3) of this section, thereby establishing the leak repair priority. An operator may use an alphabetical grade classification, i.e., Grade A for Grade 1, Grade B for Grade 2, and Grade C for Grade 3 if it has historically used such a grading designation. Operators must apply the same criteria used for initial leak grading to reinspected leaks.

(2) Gas leak classification and repair. Each operator must establish a procedure for evaluating the concentration and extent of gas leakage. When evaluating any leak, the operator must determine and document the perimeter of the leak area. If the perimeter of the leak extends to a building wall, the operator must extend the investigation inside the building. Where the reading is in an unvented, confined space, the operator must consider the rate of dissipation when the space is ventilated and the rate of accumulation when the space is resealed.

(3) Follow-up inspections. The operator must check the perimeter of the leak area with a combustible gas indicator. The operator must reinspect all leaks with residual gas remaining in the ground as soon as practical, but not later than thirty days following the repair.

(4) Leak grades.

(a) Grade 1 means a leak that represents an existing or probable hazard to persons or property, and requires immediate repair or continuous action until conditions are no longer hazardous.

(b) Grade 2 means a leak recognized as not being hazardous at the time of detection but requiring scheduled repair based on potential future hazard.

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

(d) Grade 1 and 2 leaks can only be downgraded once to a Grade 3 leak without a physical repair. After a leak has been downgraded once, the maximum repair time for that leak is twenty-one months.

(5) Leakage classification and control requirements are provided in WAC 480-93-18601.

WAC 480-93-18601   ((Table 1 -- ))Leak classification and action criteria -- Grade -- Definition -- Priority of leak repair(( -- Examples)).  



((TABLE 1 -- LEAK CLASSIFICATION

AND ACTION CRITERIA


GRADE 1

DEFINITION



A leak that represents an existing or probable hazard to persons or property and requires immediate repair or continuous action until the conditions are no longer hazardous.


((PRIORITY OF LEAK REPAIR EXAMPLES
Requires prompt action*to protect life and property and continuous action until the conditions are no longer hazardous. Leaks requiring prompt action:
1. Any leak which, in the judgment of operating personnel at the scene, is regarded as an immediate hazard.
*The prompt action in some instances may require one or more of the following:
a. Implementation of company emergency plan (192.615). 2. Escaping gas that has ignited unintentionally.
b. Evacuating premises. 3. Any indication of gas which has migrated into or under a building or tunnel.
c. Blocking off an area.
d. Rerouting traffic. 4. Any reading at the outside wall of a building or where the gas would likely migrate to the outside wall of a building.
e. Eliminating sources of ignition.
f. Venting the area, or 5. Any reading of 80% LEL or greater in a confined space.
g. Stopping the flow of gas by closing valves or other means. 6. Any reading of 80% LEL, or greater in small substructures not associated with gas likely migrate to the outside wall of a building.
h. Notifying police and fire departments.
7. Any leak that can be seen, heard, or felt and which is in a location that may endanger the general public or property.


GRADE 2

DEFINITION



A leak that is recognized as being nonhazardous at the time of detection but justifies scheduled repair based on probable future hazard.


PRIORITY OF LEAK REPAIRS EXAMPLES
Leaks should be repaired or cleared in one year but shall not exceed fifteen months from the date reported. If a Grade 2 leak occurs in a segment of pipeline which is under consideration for replacement, an additional 6 months may be added to the 15 months maximum time for repair noted above. In determining the repair priority, criteria such as the following should be considered: A. Leaks requiring action ahead of ground freezing or other adverse changes in venting conditions:
1. Any leak, which under frozen or other adverse soil conditions, would likely migrate to the outside of a building.
a. Amount and migration of gas, B. Leaks requiring action within six months:
1. Any reading of 40% 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 is likely to migrate to the outside wall of a building.
b. Proximity of gas to buildings and subsurface structures,
c. Extent of pavement, and
d. Soil type and conditions, such as frost cap, moisture and natural venting.
2. Any reading of 100% LEL or greater under a street in a wall-to-wall paved area that does not qualify as a Grade 1 leak and where the gas is likely to migrate to the outside wall of a building.
Grade 2 leaks shall be re-evaluated at least once every six months until cleared. The frequency of reevaluation should be determined by the location and magnitude of the leakage condition.
3. Any reading less than 80% LEL in small substructures not associated with gas facilities where gas would likely migrate creating a probable future hazard.
It should be recognized that Grade 2 leaks will vary greatly in degree of potential hazard. There will be some Grade 2 leaks, which when evaluated by the above criteria, will justify scheduled repair within the next 5 working days. Others will justify repair within 30 days. These situations shall be brought to the attention of the individual responsible for scheduling leakage repair at the end of the working day.
4. Any reading between 20% LEL and 80% LEL in a confined space.
5. Any reading on a pipeline operating at 30% SMYS or greater in Class 3 or 4 locations that does not qualify as a Grade 1 leak.
On the other hand, there will be many Grade 2 leaks, which because of their location and magnitude, can be scheduled for repair on a normal routine basis with periodic reinspection as necessary. 6. Any leak which in the judgment of operating personnel at the scene is of sufficient magnitude to justify scheduled repair.


GRADE 3

DEFINITION



A leak that is nonhazardous at the time of detection and can reasonably be expected to remain nonhazardous.


PRIORITY OF LEAK REPAIRS EXAMPLES
Grade 3 leaks should be re-evaluated during the next scheduled survey, or within 15 months of the reporting date, whichever occurs first, until the leak is regraded or no longer results in a reading. Leaks requiring reevaluation at periodic intervals:
1. Any reading of less than 80% LEL in small gas associated substructures such as small meter boxes or gas valve boxes.
2. 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.
3. Any reading of less than 20% LEL in a confined space.))

(1) Grade 1 leak. 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.

(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. Others in (a) of this subsection require repair within thirty days. The operator 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 reinspection as necessary.

(d) When evaluating Grade 2 leaks, operators 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 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 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 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 where gas could potentially migrate creating a probable future hazard;

(iv) Any reading between twenty percent LEL and eighty percent LEL in a confined space;

(v) Any reading on a pipeline operating at thirty percent 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 which in the judgment of operating personnel at the scene is of sufficient magnitude to justify scheduled repair.

(3) Grade 3 leak. 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 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.
