Iowa Significant Incident and Mileage Overview

The report below provides details and incident history for the pipeline systems in the state of Iowa.

The incidents reported below are limited to Significant Incidents (A) over the period 1998 to 2007 only. Each year and selected column totals provide links to focused reports showing the causes of the corresponding incidents.

The data sources for this report are the PHMSA Filtered Incident Files (1) (2) (3) and several pipeline mileage data sources as described below.

All mileages are for the year 2006 and are approximate as some data sources may not contain a complete record of state pipeline mileage for the year 2006.

See State Significant Incident Details for more information about each Significant Incident in Iowa

Where appropriate, the table columns can be sorted by clicking the corresponding column header.

Notes

  1. Significant Incidents are those incidents reported by pipeline operators with any of the following conditions are met: 1) fatality or injury requiring in-patient hospitalization. 2) $50,000 or more in total costs, measured in 1984 dollars. 3) highly volatile liquid releases of 5 barrels or more or other liquid releases of 50 barrels or more. 4) liquid releases resulting in an unintentional fire or explosion
  2. Gas distribution service lines (the connection between the distribution line and the end user) are not included in the Gas distribution mileage. The total number of such services is provided.
  3. The costs shown in the tables are in 2007 dollars. Cost of Gas lost is indexed via the Energy Information Administration, Natural Gas City Gate Prices. All other costs are adjusted via the Bureau of Economic Analysis, Government Printing Office inflation values.
  4. For years 2002 and later, property damage is estimated as the sum of all public and private costs reported in the 30-day incident report, adjusted to 2006 dollars. For years prior to 2002, accident report forms did not include a breakdown of public and private costs so property damage for these years is the reported total property damage field in the report, adjusted to 2006 dollars.
