GAS DISTRIBUTION SYSTEM
“Other” means a pipe of any material not specifically designated on the form. If you check “other
pipe,” describe it in Part I.
“Number of service” is the number of service lines, not the number of customers served.
Provide miles of main and numbers of services by decade installed in Part B, section 4.
If you do not know the decade of installation of the pipe because there are no records containing such
information, enter an estimate in the UNKNOWN column. The sum total of mileage and numbers of
services reported for Part B, section 4 should match total mileage and numbers of services reported in
sections 1, 2, and 3 in Part B.
PART C – TOTAL LEAKS AND HAZARDOUS LEAKS ELIMINATED/REPAIRED DURING
YEAR
In the appropriate column, include the total number of leaks and the number of hazardous leaks
eliminated by repair, replacement or other action during the reporting year. The number of “hazardous
leaks” eliminated or repaired during the year is reported as a performance measure for integrity
management per 192.1007(g). When reporting leaks or hazardous leaks eliminated by replacing or
abandoning a segment of pipe, count the leaks that existed in the pipe segment before it was replaced
or abandoned. Also include leaks and hazardous leaks reported on form PHMSA 7100.1, “Incident
Report Gas Distribution Systems.” A reportable incident is one described in §191.3. Do not include
leaks that occurred during testing.
A “leak” is defined as an unintentional escape of gas from the pipeline. A non-hazardous release that
can be eliminated by lubrication, adjustment, or tightening, is not a leak.
A “hazardous leak” means a leak that represents an existing or probable hazard to persons or property
and requires immediate repair or continuous action until the conditions are no longer hazardous. A
“hazardous leak” which occurs aboveground or belowground is a leak and must be reported.
Operators who do not grade leaks for hazard, but rather repair all leaks when found, need not grade
repaired leaks solely for the purpose of this report. Such operators treat all leaks as if hazardous.
Operators who do not grade leaks should report the same values for both total and hazardous leaks for
each cause.
The “number of known system leaks at the end of the year scheduled for repair” is the total number
pipeline system leaks being monitored and scheduled for repair at the end of the calendar year.
Monitored leaks also include those leaks which have been temporarily repaired until a permanent
repair can be performed. These leaks are non-hazardous unless reclassified following the operator’s
operation and maintenance procedures.
Leak causes are classified as:
CORROSION: leak resulting from a hole in the pipe or other component that was caused by galvanic,
bacterial, chemical, stray current, or other corrosive action.
5

INSTRUCTIONS FOR COMPLETING FORM PHMSA F 7100.1-1 (Rev. 09/10)
ANNUAL REPORT FOR CALENDAR YEAR 2010
GAS DISTRIBUTION SYSTEM

NATURAL FORCES: leak resulting from earth movements, earthquakes, landslides, subsidence,
lightning, heavy rains/floods, washouts, flotation, mudslide, scouring, temperature, frost heave, frozen
components, high winds, or similar natural causes.
EXCAVATION DAMAGE: leak resulting from damage caused by earth moving or other equipment,
tools, or vehicles. Include leaks from damage by operator's personnel or contractor or people not
associated with the operator.
OTHER OUTSIDE FORCE DAMAGE: Include leaks caused by fire or explosion and deliberate or
willful acts, such as vandalism.
MATERIAL OR WELDS: leak resulting from failure of original sound material from force applied
during construction that caused a dent, gouge, excessive stress, or other defect that eventually resulted
in a leak. This includes leaks due to faulty wrinkle bends, faulty field welds, and damage sustained in
transportation to the construction or fabrication site. Also include leak resulting from a defect in the
pipe material, component, or the longitudinal weld or seam due to faulty manufacturing procedures.
Leaks from material deterioration, other than corrosion, after exceeding the reasonable service life, are
reported under Other.
EQUIPMENT: leak resulting from malfunction of control/relief equipment including valves,
regulators, or other instrumentation; stripped threads or broken pipe couplings on nipples, valves, or
mechanical couplings; or seal failures on gaskets, O-rings, seal/pump packing, or similar leaks.
INCORRECT OPERATIONS: leaks resulting from inadequate procedures or safety practices, or
failure to follow correct procedures, or other operator error.
OTHER: leak resulting from any other cause, such as exceeding the service life, not attributable to the
above causes.
PART D – EXCAVATION DAMAGE
Excavation damages are reported as a measure of the effectiveness of integrity management programs
(192.1007(g)).
Report the “Number of Excavation Damages” experienced during the calendar year. For this purpose,
“Excavation Damage” means any impact that results in the need to repair or replace an underground
facility due to a weakening, or the partial or complete destruction, of the facility, including, but not
limited to, the protective coating, lateral support, cathodic protection or the housing for the line device
or facility.
Report also the “Number of Excavation Tickets” received during the year, (i.e., receipt of information
by the operator from the notification center).
PART E – EXCESS FLOW VALVE (EFV) DATA
6

INSTRUCTIONS FOR COMPLETING FORM PHMSA F 7100.1-1 (Rev. 09/10)
ANNUAL REPORT FOR CALENDAR YEAR 2010
GAS DISTRIBUTION SYSTEM
Report the number of EFVs installed on single-family residential services during the calendar year.
Report the estimated total number of EFVs in the system at the end of the calendar year. (The
“Estimated Total number of EFVs in the system” should include the “Number of EFVs installed on
single-family residential services during the calendar year”.)
PART F – TOTAL NUMBER OF LEAKS ON FEDERAL LAND REPAIRED/ELIMINATED
OR SCHEDULED FOR REPAIR
Federal Lands: As defined in 30 U.S.C. §185, federal lands means “all lands owned by the United
States except lands in the National Park System, lands held in trust for an Indian or Indian tribe, and
lands on the Outer Continental Shelf.” Indicate only those leaks repaired, eliminated, or scheduled for
repair during the reporting year, including those incidents reported on Form PHMSA F 7100.1.
PART G – PERCENT OF UNACCOUNTED FOR GAS
“Unaccounted for gas” is gas lost; that is, gas that the operator cannot account for as usage or through
appropriate adjustment. Adjustments are appropriately made for such factors as variations in
temperature, pressure, meter-reading cycles, or heat content; calculable losses from construction,
purging, line breaks, etc., where specific data are available to allow reasonable calculation or estimate;
or other similar factors.
State the amount of unaccounted for gas as a percent of total input for the 12 months ending June 30 of
the reporting year.
[(Purchased gas + produced gas) minus (customer use + company use + appropriate adjustments)]
divided by (purchased gas + produced gas) equals percent unaccounted for.
Do not report “gained” gas. If a net gain of gas is indicated by the calculations, report “0%” here.
(Decimal or fractional percentages may be entered.)
PART H – ADDITIONAL INFORMATION
Include any additional information which will assist in clarifying or classifying the reported data.
PART I - PREPARER AND AUTHORIZED SIGNATURE
PREPARER is the name of the person most knowledgeable about the report or the person to be
contacted for more information. Please include the direct phone number and email address as
applicable (e-mail address is desired but not required). It should be noted that PHMSA will use your
e-mail address to issue correspondence that is normally sent via mass mailings. “Correspondence”
includes notifications such as the annual reminder letter for Annual Report filings.
