PART 3. ADDITIONAL MINIMUM SAFETY STANDARDS

R 460.20308 Customer meters and regulators; location.

Rule 308. The requirements contained in 49 CFR 192.353, which is adopted by reference in

R 460.20606, are superseded by all of the following provisions:

(a) An operator shall install a customer’s meter and regulator outside the building, unless any

of the following apply:

(i) The distribution system operates at 10 psig or less and an outside meter set assembly is

not practical.

(ii) The building is a commercial building, industrial building, or apartment building and an

outside meter set assembly is not practical.

(iii) The building is a row-type house or house where the proximity of adjoining buildings

makes outside meter set assemblies impractical.

(b) A service line excluded under subdivision (a) of this rule must include an outside above

grade riser, if practical.

(c) If an outside meter set assembly or an outside above grade riser is installed, then the

above grade piping must be designed to prevent an external force applied to the service line

from being transferred to and damaging the inside piping.

(d) An operator shall install a meter and service regulator, whether inside or outside of a

building, in a readily accessible location and shall protect the meter and regulator from

corrosion and other damage, including but not limited to, vehicular damage if installed outside

a building. An operator shall not install a meter in a bedroom, closet, bathroom, under a

combustible stairway, or in an unventilated or inaccessible place.

(e) An operator shall ensure that a service regulator installed inside a building is located as

near as practical to the point of service line entrance.

(f) An operator shall ensure that a meter installed inside a building is located in a ventilated

place not less than 3 feet from a source of ignition or heat that might damage the meter.

(g) An operator shall ensure that the upstream regulator in a series is located outside of a

building unless it is located in a separate metering or regulating building.

R 460.20311 Test Requirements for pipelines operating below 100 psig.

Rule 311. The requirements contained in 49 CFR 192.509(b), which is adopted by reference

times the proposed maximum allowable operating pressure, whichever is greater.

(b) An operator shall ensure that the test pressure is maintained at or above the test pressure

requirement for the pipeline being tested for not less than 1 hour. However, the operator shall

test a relatively short segment for not less than 30 minutes.

R 460.20322 Maximum allowable operating pressure of pipeline containing cast-iron pipe.

Rule 322. The requirement contained in 49 CFR 192.621(a)(3), which is adopted by

reference in R 460.20606, is superseded by the requirement that a person shall not operate any

segment of a pipeline containing cast-iron pipe that has unreinforced bell and spigot joints at a

R 460.20408 Qualification of welding procedures.

Rule 408. In addition to the requirements 49 CFR 192.225, which is adopted by reference in

3

R 460.20606, an operator of pipeline facilities used in the transportation of sour gas shall use

welding procedures that conform to the welding provisions of the National Association of

Corrosion Engineers international standard NACE MR0175/ISO 15156, which is adopted by

reference in R 460.20605.

PART 5. RECORDS AND REPORTS

R 460.20501 Records.

Rule 501. (1) An operator shall maintain the information generated by any recordkeeping

requirement in these rules within the state at the operating headquarters office of each service

area and shall make the information available to the commission and its staff for inspection and

copying upon request.

(2) An operator shall maintain all of the following additional records:

(a) Maps and records showing the locations of pipelines and service lines, including lines that

have been abandoned but not removed.

(b) An up-to-date schematic drawing of station piping, which must be available at each

aboveground pressure-regulating station containing buried station components.

(3) In addition to the requirements contained in 49 CFR 192.603(b), which is adopted by

reference in R 460.20606, an operator shall establish and maintain records, make reports, and

record such information as may be reasonably required to demonstrate that the operator has

acted or is acting in compliance with these rules and 49 CFR part 192. The operator shall

maintain these records and reports for the time periods prescribed in 49 CFR Part 192; for a

minimum of 2 inspection cycles, if applicable; or for a minimum of 5 years, whichever is

longer.

R 460.20503 Reports of incidents; telephonic notice to the commission staff.

Rule 503. (1) At the earliest practicable moment following discovery, an operator shall notify

the commission staff of any of the following situations:

(a) An incident that is reportable pursuant to 49 CFR 191.5, which is adopted by reference in R

460.20606.

(b) An event resulting in estimated property damage of $10,000.00 or more including loss to

the operator and others, or both, but excluding the cost of gas lost. As used in this subdivision,

an “event” means on or relating to an operator’s facilities that may or may not involve a release

of gas.

(c) An event resulting in the loss of service to more than 100 customers.

(d) An event involving a customer's gas facility that results in a fatality or an explosion causing

structural damage.

(e) An event resulting in an unintentional release of gas estimated by the operator to be 1

million cubic feet or more or an unintentional activation of an emergency shutdown system of

any portion of a compressor station involving a release of gas.

(f) An event that causes the pressure of any portion of a pipeline system to rise above its

maximum allowable operating pressure plus the build-up allowed for operation of pressure

limiting or control devices.

(g) An event that receives or is likely to receive extensive news coverage or is significant in the

judgment of the operator, even though it did not meet the criteria of subdivision (a), (b), (c), (d),

(e) or (f) of this subrule. This subdivision is not subject to the penalty provisions of section 11 of

1969 PA 165, MCL 483.161.

(2) If additional information is received by the operator after the initial report that indicates a

different cause, more serious injury, or more serious property damage than was initially reported,

then the operator shall make a supplemental telephone report to the commission staff as soon as

practicable.

(3) When requested by the commission staff, an operator shall supplement a report made in

accordance with subrule (1) of this rule within a reasonable time, with a written report giving full

details, such as the cause of the incident or occurrence, the extent of injuries or damage, and the

steps taken, if any, to prevent a recurrence of the incident or occurrence.

R 460.20504 Reports.

Rule 504. (1) An operator shall concurrently submit a written report that is required to be filed

with any federal agency by 49 CFR part 191, which is adopted by reference in R 460.20606, to

the commission at P.O. Box 30221, Lansing, Michigan 48909-0221 or as directed by the

commission staff.

(2) An operator required to submit an annual report in accordance with 49 CFR 191.11 and 49

CFR 191.17, which are adopted by reference in R 460.20606 of these rules, shall also submit a

supplemental report to the commission staff. In the supplemental report, the operator shall

subdivide the information in the reports required under 49 CFR 191.11 and 49 CFR 191.17 into

specific regions identified by the commission staff. The staff shall identify and communicate

these regions to the operator by the end of the calendar year for which the reports are being

submitted. As used in this rule, “regions” means geographical, operational, or functional areas of

the operator’s system. These supplemental reports are to be submitted no later than the dates

required in 49 CFR 191.11 and 49 CFR 191.17 and in a similar format.
