Human error causes a partial shutdown of Texas nuclear plant

South Texas Project

Human error appears to have caused a partial shutdown last Friday at the South Texas Project, one of the state’s two nuclear plants.

Last week, prices spiked in the wholesale electricity market. On Monday the 16th, wholesale electricity, which had been selling for less than $30 per megawatt-hour spiked to more than $2,000. That’s an increase of more than 7,000 percent. Prices also spiked several times to the $1,000 level. A price spike of $2,200 is especially startling, given that the regulatory cap is set at $2,250. That is, the wholesale prices legally could not have gone much higher. At the same time, according to the Electric Reliabiilty Council of Texas (ERCOT), who manages the Texas electricity grid, a new record for statewide power use was set.

Then, to top off the week, Unit 1 of the South Texas Project apparently tripped off (also known in the industry as a SCRAM – an acronym for safety control rod axe man but which is essentially an emergency shutdown of a nuclear reactor).

The event, first reported in a trade journal SNL Power Daily, was apparently caused by human error. “The NRC said in its Aug. 23 event report that the unit experienced an automatic reactor trip that was caused by an inadvertent turbine signal initiated during testing,” reported SNL’s Jay Hodgkins, citing the U.S. Nuclear Regulatory Commission. The publication reported that power was restored by Monday. It’s unclear whether the outage contributed to the price spikes, although that seems likely.

I guess I’ll take a contribution to a price spike over a meltdown any day, but still kind of scarey!

TCEQ POSTS INTERACTIVE BARNETT SHALE MAP

Live downwind from the Barnett Shale ?

The Texas Commission on Environmental Quality posted an interactive map of the Barnett Shale on its website that allows you to see the latest data from the various air quality monitoring sites near natural gas drilling and pipeline facilities.

Be forwarned however that the information contained on this website is not for the faint of heart or the casual internet surfer. Those who venture through the maze that is the TCEQ website, without much beyond a basic familiarity of the terms associated with measuring the sundry compounds that can escape from gas operation facilities, might find themselves challenged to understand what the map offers.

TCEQ has been under pressure from North Texas lawmakers and from various interest groups to provide the public with as much information as possible about how gas operations in the urbanized Barnett Shale might be affecting air quality. And the introduction of the map comes just four days after the chairmen of the House and Senate committees that oversee environmental regulations prompted the agency to more than double the number of air monitoring sites in the Barnett Shale.

TCEQ also announced today that it plans to hold an open house in the Barnett Shale area in October that will feature interactive displays and presentations where residents can learn about specific regulatory activities in the area. Details about when and where the open house will take place are not yet available but we will let you know as soon as we know.

TCEQ has said that the U.S. Environmental Protection Agency evaluated its monitoring operations in the tiny town of Dish and found no reason to doubt the validity of the test results.

Report Shows Dangers of Coal Ash Waste Sites Throughout the US

In Winter of 2008 a coal ash slurry pond in Tennessee broke its damn, contaminating miles of downstream waterways and people’s homes with deadly carcinogens and other toxic substances. At the time it was called the worst environmental disaster since the Exxon Valdez and brought a wake up call to the EPA that this waste product was entirely under-regulated. EPA now stands poised to set new regulations on coal ash waste, but the coal industry is lobbying strenuously against it, advocating for a much weaker standard that will do little to change the status quo.

The Environmental Integrity Project (EIP) has just released a report called In Harm’s Way which takes a look at groundwater contamination surrounding coal ash waste sites throughout the country. The report showed that contaminants at 39 coal-waste sites across 21 states have leached into the groundwater. Many coal ash sites did not have enough data available to show any meaningful results, particularly here in Texas, but the Fayette coal plant (which Austin is a partial owner in) showed considerable contamination beneath their site. Adam Engelman, Environmental Analyst with EIP, stated that:

At every one of the coal ash dump sites equipped with groundwater monitoring wells — concentrations of heavy metals such as arsenic or lead exceed federal health-based standards for drinking water, with concentrations at LCRA’s Fayette Power Project reaching as high as 4 times the state standard for selenium and twice the state standard for arsenic.

The report shows that coal ash itself is a disaster simply by existing, regardless of catastrophic events like what happened in Tennessee almost two years ago. EPA must not give into industry lobbyists and pass weak regulations that will fail public health and the environment. Visit Sierra Club’s Coal Ash website for information on an EPA hearing near you, and to sign up to speak at the hearings. If you cannot make the hearings you can also submit online comments here – be sure to ask EPA to adopt the strictest regulations possible.

In order to make a profit, coal companies rely on making the public pay for the damage they cause. We should no longer have to bear the cost of their mistakes and irresponsibility.
