Book Description
Pipeline Safety - Expanding the Use of Excess Flow Valves in Gas Distribution Systems to Applications Other Than Single-Family Residences (US Pipeline and Hazardous Materials Safety Administration Regulation) (PHMSA) (2018 Edition) The Law Library presents the complete text of the Pipeline Safety - Expanding the Use of Excess Flow Valves in Gas Distribution Systems to Applications Other Than Single-Family Residences (US Pipeline and Hazardous Materials Safety Administration Regulation) (PHMSA) (2018 Edition). Updated as of May 29, 2018 Excess flow valves (EFV), which are safety devices installed on natural gas distribution pipelines to reduce the risk of accidents, are currently required for new or replaced gas service lines servicing single-family residences (SFR), as that phrase is defined in 49 CFR 192.383(a). This final rule makes changes to part 192 to expand this requirement to include new or replaced branched service lines servicing SFRs, multifamily residences, and small commercial entities consuming gas volumes not exceeding 1,000 Standard Cubic Feet per Hour (SCFH). PHMSA is also amending part 192 to require the use of either manual service line shut-off valves (e.g., curb valves) or EFVs, if appropriate, for new or replaced service lines with meter capacities exceeding 1,000 SCFH. Lastly, this final rule requires operators to notify customers of their right to request installation of an EFV on service lines that are not being newly installed or replaced. PHMSA has left the question of who bears the cost of installing EFVs on service lines not being newly installed or replaced to the operator's rate-setter.

Book Description
Pipeline Safety - Integrity Management Program for Gas Distribution Pipelines (US Pipeline and Hazardous Materials Safety Administration Regulation) (PHMSA) (2018 Edition) The Law Library presents the complete text of the Pipeline Safety - Integrity Management Program for Gas Distribution Pipelines (US Pipeline and Hazardous Materials Safety Administration Regulation) (PHMSA) (2018 Edition). Updated as of May 29, 2018 PHMSA proposes to amend the Federal Pipeline Safety Regulations to require operators of gas distribution pipelines to develop and implement integrity management (IM) programs. The purpose of these programs is to enhance safety by identifying and reducing pipeline integrity risks. The IM programs required by the proposed rule would be similar to those currently required for gas transmission pipelines, but tailored to reflect the differences in and among distribution systems. In accordance with Federal law, the proposed rule would require operators to install excess flow valves on certain new and replaced residential service lines, subject to feasibility criteria outlined in the rule. Based on the required risk assessments and enhanced controls, the proposed rule also would establish procedures and standards permitting risk-based adjustment of prescribed intervals for leak detection surveys and other fixed-interval requirements in the agency's existing regulations for gas distribution pipelines. To further minimize regulatory burdens, the proposed rule would establish simpler requirements for master meter and liquefied petroleum gas (LPG) operators, reflecting the relatively lower risk of these small pipeline systems.

Book Description
The U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA) is responsible for ensuring the safe, reliable, and environmentally sound operation of the nation's natural gas and hazardous liquid pipelines. Regulations adopted by PHMSA for gas pipelines are provided in 49 CFR 192, and spacing requirements for valves in gas transmission pipelines are presented in 49 CFR 192.179. The present report describes the findings of a scoping study conducted by Oak Ridge National Laboratory (ORNL) to assist PHMSA in assessing the safety impact of system valve spacing. Calculations of the pressures, temperatures, and flow velocities during a set of representative pipe depressurization transients were carried out using a one-dimensional numerical model with either ideal gas or real gas properties for the fluid. With both ideal gas and real gas properties, the high-consequence area radius for any resulting fire as defined by Stevens in GRI-00/0189 was evaluated as one measure of the pipeline safety. In the real gas case, a model for convective heat transfer from the pipe wall is included to assess the potential for shut-off valve failures due to excessively low temperatures resulting from depressurization cooling of the pipe. A discussion is also provided of some additional factors by which system valve spacing could affect overall pipeline safety. The following conclusions can be drawn from this work: (1) Using an adaptation of the Stephens hazard radius criteria, valve spacing has a negligible influence on natural gas pipeline safety for the pipeline diameter, pressure range, and valve spacings considered in this study. (2) Over the first 30 s of the transient, pipeline pressure has a far greater effect on the hazard radius calculated with the Stephens criteria than any variations in the transient flow decay profile and the average discharge rate. (3) Other factors besides the Stephens criteria, such as the longer burn time for an accidental fire, greater period of danger to emergency personnel, increased unavoidable loss of gas, and possible depressurization cooling of the shut-off valves may also be important when deciding whether a change in the required valve spacing would be beneficial from a safety standpoint. (4) The average normalized discharge rate of [lambda]{sub avg} = 0.33 assumed by Stephens in developing his safety criteria is an excellent conservative value for natural gas discharge at the pressures, valve spacings, and pipe diameter used in this study. This conclusion remains valid even when real rather than ideal gas properties are considered in the analysis. (5) Significant pipe wall cooling effects (T{sub w}

Pipeline Safety - Updates to Pipeline and Liquefied Natural Gas Reporting Requirements (US Pipeline and Hazardous Materials Safety Administration Regulation) (PHMSA) (2018 Edition) The Law Library presents the complete text of the Pipeline Safety - Updates to Pipeline and Liquefied Natural Gas Reporting Requirements (US Pipeline and Hazardous Materials Safety Administration Regulation) (PHMSA) (2018 Edition). Updated as of May 29, 2018 This Notice of Proposed Rulemaking seeks to revise the Pipeline Safety Regulations to improve the reliability and utility of data collections from operators of natural gas pipelines, hazardous liquid pipelines, and liquefied natural gas (LNG) facilities. These revisions will enhance PHMSA's ability to: understand, measure, and assess the performance of individual operators and industry as a whole; integrate pipeline safety data to allow a more thorough, rigorous, and comprehensive understanding and assessment of risk; and expand and simplify existing electronic reporting by operators. These revisions will improve both the data and the analyses PHMSA relies on to make critical, safety-related decisions, and will facilitate PHMSA's allocation of inspection and other resources based on a more accurate accounting of risk.

Book Description
" Pipelines are a relatively safe mode of transportation for hazardous liquid and natural gas and are regulated by the Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) and state entities. Included in the nation's pipeline network are an estimated 200,000 or more miles of onshore "gathering" pipelines, which transport products to processing facilities and larger pipelines. (See figure.) Many of these pipelines have not been subject to federal regulation based on their generally rural location and low operating pressures. While incidents involving gathering pipelines regulated by PHMSA have resulted in millions of dollars in property damage in recent years, comparable statistics for federally unregulated gathering pipelines are unknown. This report identifies (1) the safety risks that exist, if any, with onshore hazardous liquid and natural gas gathering pipelines that are not currently under PHMSA regulation and (2) the practices states use to help ensure the safety of these pipelines. GAO surveyed state pipeline safety agencies in all 50 states and the District of Columbia; interviewed officials at PHMSA, state pipeline safety agencies, pipeline companies, and industry associations; and analyzed data and regulations.
