Two Houston Companies Will Pay $1 Million for Natural Gas Pipeline Spills

Mid-America Pipeline Company, LLC (MAPCO), and Enterprise Products Operating LLC (Enterprise), of Houston, have agreed to pay a civil penalty of more than $1 million to the United States to settle violations of the federal Clean Water Act related to three natural gasoline pipeline spills in Iowa, Kansas and Nebraska.

As part of a consent decree lodged today in U.S. District Court in Omaha, Neb., and in addition to paying the $1,042,000 civil penalty, the companies have agreed to undertake various measures aimed at reducing external threats to their pipeline, enhance their reporting of spills, and spend at least $200,000 to identify and prevent external threats to the pipeline involved in the spills.

MAPCO owns and Enterprise operates the 2,769-mile West Red Pipeline, which transports mixed natural gasoline products between Conway, Kan., and Pine Bend, Minn. The settlement resolves Clean Water Act violations related to three spills that occurred along the pipeline:

A March 29, 2007, rupture near Yutan, Neb., which caused the discharge of approximately 1,669 barrels of natural gasoline directly into an unnamed ditch and Otoe Creek.
An April 23, 2010, rupture near Niles, Kan., which caused the discharge of approximately 1,760 barrels of natural gasoline directly into an unnamed ditch, Cole Creek, Buckeye Creek and the Solomon River.

An August 13, 2011, rupture near Onawa, Iowa, which caused the discharge of approximately 818 barrels of natural gasoline directly into the Missouri River.

“More than 20,000 miles of pipeline, carrying oil and petroleum products, cross the states of Iowa, Kansas, Missouri and Nebraska in EPA’s Region 7,” EPA Regional Administrator Karl Brooks said. “A frequent cause of pipeline breaks is the action of third parties during farming and excavation. This settlement requires the defendants to honor a schedule of pipeline inspections on the ground and from the air, and reach out to local agencies, contractors and excavators to make sure they are more fully aware of pipeline locations and depths.”

“This settlement requires proactive vigilance to ensure that our soil and waterways are protected from contaminants,” said Deborah R. Gilg, U.S. Attorney for the District of Nebraska. “The agreement will result in safer pipeline operations and that will be good for Nebraska’s environment.”

In addition to the proactive inspections and outreach efforts, the settlement also requires MAPCO and Enterprise to spend $200,000 to relocate, cover, lower or replace pipeline segments; install new remote shutoff valves; install new physical protections such as fences or concrete barriers; and install other new equipment, structures or systems to prevent spills from reaching navigable waters.

The consent decree is subject to a 30-day public comment period and court approval.

Wikipedia: Natural gasoline is a natural gas liquid with a vapor pressure intermediate between natural gas condensate and liquefied petroleum gas and has a boiling point within the range of gasoline. The typical gravity of natural gasoline is around 80 API. This hydrocarbon mixture is liquid at ambient pressure and temperature. It is volatile and unstable but can be blended with other hydrocarbons to produce commercial gasoline. The natural gas hydrocarbons mixture is mostly pentanes and heavier (smaller amounts of C6 and C6+), extracted from natural gas, that meets vapor pressure, end-point, and other specifications for natural gasoline set by the Gas Processors Association[1]. Includes isopentane which is a saturated branch-chain hydrocarbon, (C5H12), obtained by fractionation of natural gasoline or isomerization of normal pentane.[2] Natural gasoline is often used to denature ethanol produced for E85 "flexible fuel". Natural gasoline has a lower octane content than conventional commercial distilled gasoline, so it cannot normally be used by itself for fuel for modern automobiles. However, when mixed with high concentrations of ethanol such as mid-level blends, like E50 or E85, the octane content is raised high enough to be used easily in flex-fuel vehicles. It may be sourced from production of natural gas wells (See "drip gas") or may be produced by extraction processes [3] in the field, as opposed to refinery cracking of conventional gasoline.

That is really poor. Just what are the qualifications of people writing these articles and even worse, who is doing the editing?

Good point. It should say gasoline. I will go in and correct it.

What is natural gasoline. I have never heard of such a product. Is this article about natural gas (a gas not a liquid) or gasoline which is a liquid. A natural gas pipeline would not spill liquid product.
