Current through Register Vol. 50, No. 6, June 20, 2024
A. As
				  used in this Part:
Abandoned
-permanently removed from
					 service.
Active Corrosion
-continuing corrosion
					 that, unless controlled, could result in a condition that is detrimental to
					 public safety.
Administrator
-the administrator, Pipeline
					 and Hazardous Materials Safety Administration or his or her delegate.
Alarm
-an audible or visible means of
					 indicating to the controller that equipment or processes are outside
					 operator-defined, safety-related parameters.
Building
-any structure in which gas can
					 accumulate.
Business
-a permanent structure occupied
					 for the express usage of wholesale or retail sales, services, the manufacture
					 or storage of products, or a public building.
Business District
-an area of two or more
					 businesses within 100 yards (300 feet) of each other and within 100 yards along
					 the linear length of any gas pipeline. The district will extend 100 feet past
					 the defined boundaries of the last business in the district.
Commissioner
-the Commissioner of
					 Conservation or any person to whom he has delegated authority in the matter
					 concerned.
Control Room
-an operations center staffed
					 by personnel charged with the responsibility for remotely monitoring and
					 controlling a pipeline facility.
Controller
-a qualified individual who
					 remotely monitors and controls the safety-related operations of a pipeline
					 facility via a SCADA system from a control room, and who has operational
					 authority and accountability for the remote operational functions of the
					 pipeline facility.
Customer Meter
-the meter that measures the
					 transfer of gas from an operator to a customer.
Composite Materials-
materials used to make
					 pipe or components manufactured with a combination of either steel and/or
					 plastic and with a reinforcing material to maintain its circumferential or
					 longitudinal strength.
Distribution Line
-a pipeline other than a
					 gathering or transmission line.
Electrical Survey
-a series of closely
					 spaced pipe-to-soil readings over pipelines which are subsequently analyzed to
					 identify locations where a corrosive current is leaving the pipeline.
Exposed Underwater Pipeline
-an underwater
					 pipeline where the top of the pipe protrudes above the underwater natural
					 bottom (as determined by recognized and generally accepted practices) in waters
					 less than 15 feet (4.6 meters) deep, as measured from mean low water.
Engineering Critical Assessment (ECA)
-a
					 documented analytical procedure based on fracture mechanics principles,
					 relevant material properties (mechanical and fracture resistance properties),
					 operating history, operational environment, in-service degradation, possible
					 failure mechanisms, initial and final defect sizes, and usage of future
					 operating and maintenance procedures to determine the maximum tolerable sizes
					 for imperfections based upon the pipeline segment maximum allowable operating
					 pressure.
Entirely Replaced Onshore Transmission Pipeline
					 Segments L-
for the purposes of
					 §1139 and
					 2734, where 2 or more miles, in the aggregate, of onshore transmission pipeline
					 have been replaced within any 5 contiguous miles of pipeline within any
					 24-month period.
Gas
-natural gas, flammable gas, or gas
					 which is toxic or corrosive.
Gathering Line
-a pipeline that transports
					 gas from a current production facility to a transmission line or main.
Gulf of Mexico
and
its
					 Inlets
-the waters from the mean high water mark of the coast of the
					 Gulf of Mexico and its inlets open to the sea (excluding rivers, tidal marshes,
					 lakes, and canals) seaward to include the territorial sea and Outer Continental
					 Shelf to a depth of 15 feet (4.6 meters), as measured from the mean low
					 water.
Hazard to Navigation
-for the purposes of
					 this Part, a pipeline where the top of the pipe is less than 12 inches (305
					 millimeters) below the underwater natural bottom (as determined by recognized
					 and generally accepted practices) in waters less than 15 feet (4.6 meters)
					 deep, as measured from the mean low water.
High Pressure Distribution System
-a
					 distribution system in which the gas pressure in the main is higher than the
					 pressure provided to the customer.
Line Section
-a continuous run of
					 transmission line between adjacent compressor stations, between a compressor
					 station and storage facilities, between a compressor station and a block valve,
					 or between adjacent block valves.
Listed Specification
-a specification
					 listed in Section I of Appendix B of this Subpart.
Low-Pressure Distribution System
-a
					 distribution system in which the gas pressure in the main is substantially the
					 same as the pressure provided to the customer.
Main
-a distribution line that serves as a
					 common source of supply for at least one service line.
Master Meter System
-a pipeline system for
					 distributing gas within, but not limited to, a definable area such as a mobile
					 home park, housing project, apartment complex or university, where the operator
					 purchases meter gas from an outside source for resale through a gas pipeline
					 system. The gas distribution pipeline system supplies the ultimate consumer who
					 either purchases the gas directly through a meter or by other means, such as
					 rents.
Maximum Actual Operating Pressure
-the
					 maximum pressure that occurs during normal operations over a period of one
					 year.
Maximum Allowable Operating Pressure
					 (MAOP)
-the maximum pressure at which a pipeline or segment of a
					 pipeline may be operated under this Subpart.
Municipality
-a city, parish, or any other
					 political subdivision of Louisiana.
Moderate Consequence Area
-
a. an onshore area that is within a potential
				  impact circle, as defined in § 3303, containing either:
i. five or more buildings intended for human
				  occupancy; or
ii. any portion of
				  the paved surface, including shoulders, of a designated interstate, other
				  freeway, or expressway, as well as any other principal arterial roadway with 4
				  or more lanes, as defined in the Federal Highway Administration's Highway
				  Functional Classification Concepts, Criteria and Procedures, Section 3.1 of the
				  2013 Edition (see:
https://www.fhwa.dot.gov/planning/processes/statewide/related/highway_functional_classifications/fcauab.pdf
),
				  and that does not meet the definition of high consequence area, as defined in
				  §3303;
