125 PROPOSED INSTALLATION REPORT

(End of Attachment A)

Retrofitting of transmission lines to allow inline inspections

Rationale:  The technology for inline inspection of pipelines is continuously advancing and CFR 49, Part 192 recognizes this advancement in technology by requiring new transmission pipelines to be "piggable" (capable of being inspected by inline inspection tools).  However, our current aging pipeline infrastructure may contain conditions which may or may not allow such inline inspection tools to be used.  The new rule aims to promote the use of inline inspection technology in natural gas transmission pipelines throughout California.

Description:  The rule will require operators of natural gas transmission lines to establish a program that will continuously evaluate and prioritize transmission pipelines that are currently considered "non-piggable" to be retrofitted to allow inline inspection tools.  The rule will require operators to make continuous upgrades throughout their transmission systems such that, in a specified period of time, all transmission lines in California can accommodate inline inspection tools.

Require operators to perform evaluations for installing automatic or remote controlled valves on transmission pipelines 

Rationale: When a transmission line fails, it is important that an operator be able to respond in a timely fashion to a failure, especially if the failure is in a High Consequence (as defined in CFR 49, Part 192, Subpart O), Class 3 or Class 4 area.  Long distances and availability of personnel can impact this response.  A delayed response can result in loss of life and property damage. 

Description: This rule would require utilities to develop criteria for installing either automatic or remotely controlled valves located in High Consequence, Class 3 or Class 4 areas.  Considerations must include the location of the valve and the estimated response times.

Require operators to strengthen emergency response procedures

Rationale: Current rules in General Order 112-E and 49 CFR, Part 192 do not have specific incident response time requirements for operators. 49 CFR §192.615 (a)(3) requires "prompt and effective response to a notice of each type of emergency". "Prompt" and "effective" response by an operator should be improved upon in light of recent events. 

Description: The new rule would require that each operator to establish a program to monitor and analyze emergency response data in order to improve incident response time and response effectiveness. 

Requirement for the gas quality monitoring

Rationale: Liquid intrusion or sulfur buildup in an operator's pipeline can result in equipment failure which can cause the pipeline system pressure to exceed its Maximum Allowable Operating Pressure (as defined in CFR 49, Part 192).  With a program in place to monitor, analyze, and prevent liquid intrusion or sulfur buildup in a pipeline system, the likelihood of additional equipment failures due to liquid intrusion or sulfur buildup would be minimized.

Description: The new rule would require that each operator have a program in place to monitor, analyze, and prevent liquid intrusion and sulfur buildup in its pipeline system. 

Test requirements for pipelines operating below 100 psig and service lines

Rationale: Current rules do not specify durations for pressure tests for both distribution mains operating below 100 psig and service lines.  Additionally, there is no specific requirement for pressure test on service lines to be operated at less than 1 psig.  Instead, 49 CFR Part 192.511(a) contains a general statement requiring service lines to be tested for leaks at the operating pressure.  The proposed rule will define minimum pressure test durations and provide consistency for pressure test requirements for both distribution mains operating below 100 psig and service lines

Description: Consistent with the pressure test requirements for mains operating below 1 psig, the proposed rule will require new service lines to be operated below 1 psi gage to be pressure tested at a minimum pressure of 10 psi gage.  The proposed rule will also require short sections of pipeline used for repairs to be pressure tested at the operating pressure, at a minimum.  The minimum pressure test durations for new installations and repairs should be explored during the rulemaking process.

Clearance between gas pipelines and other subsurface structures

Rationale: The Commission's General Order 128 provides clearance requirements for underground electric and communication systems from other underground utilities, including gas pipelines.  The proposed rule will include these clearance requirements to provide uniformity for all underground utilities operators throughout California.

Description: The new rule will maintain the current requirement for transmission lines per 49 CFR 192.325, and contain similar clearance requirements as General Order 128, Rule 31.4.  It will also address instances wherein, if the required separations cannot be obtained, the party installing facilities will be required to contact the operator of the existing gas facilities near their installation to ensure that reduced separation will not compromise the integrity of the existing gas facilities.

Incorporating One-Call Law requirements for marking underground facilities

Rationale: Currently, CFR 49, Part 192, section 192.614(a) requires operators of buried pipelines to participate in "a written program to prevent damage to that pipeline from excavation activities."  The operator can substantially meet the requirements of 192.614 by participating in a qualified one-call system, and California has such a program that operators participate in (Government Code Sections 4216-4216.9).  The One Call Law has certain requirements for both pipeline operators and excavators.  One of these requirements addresses the need to accurately mark their facilities.  Inaccurate markings are one cause of dig-ins.  While section 192.614 provides an option for a utility to participate in the one call system, it does not mandate utilities to accurately mark their facilities. 

Description: This rule would incorporate the one call law by reference it into the general order and require jurisdictional utilities to accurately mark their facilities, as well as meet all other requirements contained therein. 

Report Cathodic Protection deficiencies and provide a timetable for remedial actions

Rationale: Cathodic Protection (CP) is an integral part of the system that prevents buried underground metallic pipe from rusting.  The longer an underground piping system stays without this protection, the more the pipe will rust and compromise its integrity.  For a variety of reasons, pipeline operators can and do take extended periods of time to restore areas to proper levels (defined in Part 192, Appendix D).  Some of the causes are within the operator's control, and some are outside of the operator's control. 

Description: This rule would require operators to report to the Utilities Reliability and Safety Branch (USRB) any CP systems that remain down for a period longer than six months.  It would also require operators to provide a timetable for restoring the CP, and the reasons for the delay.  This would provide the USRB a method to proactively monitor CP deficiencies.

Cover requirements for transmission lines

Rationale:  49 CFR, Part 192, section 192.327(c) currently allows installation of transmission lines or mains with less than the minimum cover required, provided that it has additional protection to withstand anticipated external loads.  However, this requirement does not address other external threats which the pipe may be susceptible to due to reduced cover such as excavation damage.

Description:  The rule will require operators to establish a program to monitor their transmission pipelines in order to identify segments, with reduced underground cover. The program must provide additional damage prevention measures for such segments.  Additionally, the new rule will require operators to continuously monitor these transmission pipelines for any damages caused, directly or indirectly, by the reduced cover and take corrective actions.

Reporting problems associated with mechanical/compression fittings

Rationale: Gas pipeline operators use mechanical fittings for joining and pressure sealing of two pipes together. Properly installed and supported fittings and couplings successfully connect steel, cast iron, copper, and plastic pipes. Past incidents indicate that failures occur when the couplings are incorrectly installed or supported or installed with components that differ from the original manufacturer specifications, modified prior to installation, or have entirely missing parts. Pipeline and Hazardous Materials Safety Administration (PHMSA) issued an advisory bulletin on March 4, 2008 to warn gas pipeline operators using mechanical couplings about the risks involved in installing mechanical/compression fittings. 49 CFR, Part 192 does not have specific requirements applicable to mechanical/compression fitting installations and failure analysis.

Description:  In the light of PHMSA's advisory bulletin, this rule would require operators to review procedures for using mechanical couplings, including coupling design and installation, and ensure that they meet manufacturer recommendations and take action to prevent future failures and minimize risks associated with mechanical/compression fittings.

Assessment of existing Meter Set Assemblies (MSA) and other pipeline components to protect them from excessive snow and ice loading

Rationale: Recent gas pipeline incidents indicated that excessive snow and ice accumulation on pipeline facilities can cause failures due to additional stress imposed on MSAs or other pipeline components. On March 10, 2008, PHMSA issued an advisory bulletin advising owners and operators of gas pipelines of the need to take steps to prevent damage to pipeline facilities from accumulated snow or ice. Current federal regulations do not require operators to monitor the potential impact of excessive snow and ice on these facilities or to inform the public about possible hazards from snow and ice accumulation on regulators and other pipeline facilities.

Description: This rule would require all California gas pipeline operators to initiate an assessment program to evaluate the condition of MSAs which are susceptible to snow and ice accumulation, replace or recondition all existing MSAs that are not adequately supported or protected from excessive snow and ice load and install protective barriers and support for all new MSA installations.

Require operators to identify threats along their pipelines and come up with a plan to mitigate the threats, including research and development (192.919)

Rationale: Current federal rules require operators to identify potential threats to each covered pipeline segment and the information supporting the threat identification, specify the methods selected to assess the integrity of the line pipe, and provide a schedule to complete integrity assessments. However, they do not specify the requirements to provide details about mitigation techniques they would use to comply with standards.

Description:This rule would require gas pipeline operators to provide details on their threat identification, assessment of pipeline conditions, mitigative actions to correct identified anomalies, defects, and imperfections and reassessment intervals for all threats, development of an improved management and analysis processes that integrate all available integrity-related data and information and assess the risks associated with pipeline segments in HCAs, any other damage prevention programs and any other preventive activities to implement additional risk control measures such as installing computerized monitoring and leak detection systems, replacing pipe segments with pipe of heavier wall thickness, providing additional training to personnel on response procedures, conducting drills with local emergency responders and implementing additional inspection and maintenance programs.
