 CHAPTER I--RESEARCH AND SPECIAL PROGRAMS ADMINISTRATION, DEPARTMENT OF 
                       TRANSPORTATION (CONTINUED)
 
PART 191--TRANSPORTATION OF NATURAL AND OTHER GAS BY PIPELINE; ANNUAL REPORTS, INCIDENT REPORTS, AND SAFETY-RELATED CONDITION REPORTS--Table of Contents
 
Sec. 191.23  Reporting safety-related conditions.

    (a) Except as provided in paragraph (b) of this section, each 
operator shall report in accordance with Sec. 191.25 the existence of 
any of the following safety-related conditions involving facilities in 
service:
    (1) In the case of a pipeline (other than an LNG facility) that 
operates at a hoop stress of 20 percent or more of its specified minimum 
yield strength, general corrosion that has reduced the wall thickness to 
less than that required for the maximum allowable operating pressure, 
and localized corrosion pitting to a degree where leakage might result.
    (2) Unintended movement or abnormal loading by environmental causes, 
such as an earthquake, landslide, or flood, that impairs the 
serviceability of a pipeline or the structural integrity or reliability 
of an LNG facility that contains, controls, or processes gas or LNG.
    (3) Any crack or other material defect that impairs the structural 
integrity or reliability of an LNG facility that contains, controls, or 
processes gas or LNG.
    (4) Any material defect or physical damage that impairs the 
serviceability of a pipeline that operates at a hoop

stress of 20 percent or more of its specified minimum yield strength.
    (5) Any malfunction or operating error that causes the pressure of a 
pipeline or LNG facility that contains or processes gas or LNG to rise 
above its maximum allowable operating pressure (or working pressure for 
LNG facilities) plus the build-up allowed for operation of pressure 
limiting or control devices.
    (6) A leak in a pipeline or LNG facility that contains or processes 
gas or LNG that constitutes an emergency.
    (7) Inner tank leakage, ineffective insulation, or frost heave that 
impairs the structural integrity of an LNG storage tank.
    (8) Any safety-related condition that could lead to an imminent 
hazard and causes (either directly or indirectly by remedial action of 
the operator), for purposes other than abandonment, a 20 percent or more 
reduction in operating pressure or shutdown of operation of a pipeline 
or an LNG facility that contains or processes gas or LNG.
    (b) A report is not required for any safety-related condition that--
    (1) Exists on a master meter system or a customer-owned service 
line;
    (2) Is an incident or results in an incident before the deadline for 
filing the safety-related condition report;
    (3) Exists on a pipeline (other than an LNG facility) that is more 
than 220 yards (200 meters) from any building intended for human 
occupancy or outdoor place of assembly, except that reports are required 
for conditions within the right-of-way of an active railroad, paved 
road, street, or highway; or
    (4) Is corrected by repair or replacement in accordance with 
applicable safety standards before the deadline for filing the safety-
related condition report, except that reports are required for 
conditions under paragraph (a)(1) of this section other than localized 
corrosion pitting on an effectively coated and cathodically protected 
pipeline.
