A Flawed Process: Fast Tracking Dirty Coal Power Plant Permits
Stanley Feld M.D.,FACP,MACE
It seems as if it is very hard for the people’s voice to be heard in Texas. Contacting the Governor is harder than paying the water bill in Franz Kafka’s book “The Castle”. Even if we were listened to, we would not be heard by our governor. He still believes building the Dirty Coal Plants and polluting the state and cities in Texas is good for the growth of Texas even if the majority of the people disagree. Presently, Texas is in the top six for pollution. I bet these coal plants will propel us to “Number 1”. Governor Perry’s office called the opposition of the Dirty Coal Power Plants a liberal Democratic plot. I call it a refusal to understand the issue on the part of the governor.
The following quotes appeared in the Herald Democrat December 8, 2006
“Dozens of David’s lined up here (Bonham,Texas) Thursday (December 7,2006) to see if State Administrative Law Judge Kerry Sullivan would give them a rock to use in the battle against Goliath TXU.”
“Ranchers and those who have built wetlands and wildlife sanctuaries fear devastation of their land, ponds and trees from acid rain caused by sulfur dioxide (emission from the Dirty Coal Plant proposed in Savoy Texas.)”
In addition to sulfur, people in Fannin and Grayson County are going to be exposed to 72,480,000,000 billion micrograms of Mercury a year (160 lbs). All of this Mercury is additive each year. Mercury affects fetal and infant brain development with resultant increase in Autism, attention deficit syndrome and loss of memory in adults. Maybe the increase in Alzheimer’s disease is secondary to the increase in pollution in the country.
“TXU said the plant will emit 3,787 tons(7,574,000 lbs.) of sulfur dioxide each year, less than current coal-fired plants and within the U.S. Environmental Protection Agency’s limits.”
The lowering of these toxic levels of Sulfur and the resulting conversion to sulfuric acid when reacting to the air have be stalled by the Bush Administration. The administration does not believe in the existence of acid rain or the global warming resulting from excess production of carbon dioxide. This belief is held in spite of the abundance evidence for it effect. Nitrogen effluent will produce 1894 tons per year (3,788,000 lbs.) resulting in increased production of ozone. The particulate matter from the Savoy Texas Dirty Coal Plants will be 1515 tons( 3,030,000 lbs) per year. How many of us think this is healthy for the kids of North Central Texans in general and Grayson and Fannin County residents in particular.
However we, the people of Texas, will be stuck with the high levels for the next 50 years long after this administration is gone. I thought people were wrong when they said these groups of government officials were not compassionate. They are not compassionate and they do not listen to the will of the people.
“When the judge found there were more than 40 people who live within 10 miles of the plant at the hearing asking for status as individuals, he said, “I am required by law to hold this hearing in a way to have an organized process for the development of the evidence that will focus on issues and that can be cross examined effectively. And there is simply no way we can have this many active participants prepare for this hearing and then formally participate in it.”
“Reacting to Sullivan’s statement that there were too many parties seeking status as parties in the case, Dr. Stanley Feld said that there seemed to him to be evidence the process is moving too fast. Feld added there should be more hearings held close to the plant so local people won’t have to travel to Austin to decide a local issue.”
“With all due respect to everyone, you are working within the parameters you have to work in,” Feld said. “I can see that clearly. What has happened is there is something wrong with the system of parameters when local people didn’t know anything about it (the proposed coal plants) and haven’t been able to express their opinion. With the rules that have been set up, Texas Electric (the former name of part of TXU) has said ‘OK, let’s batch everyone together and make it quicker.’”
This was a very good move on TXU’s part. TXU would love to shut as many people up as they can. What is magical about 10 miles? What is so wrong with educating your neighbor about the risk we will permit in our neighborhood? Presently we get 70% of our electricity from Dirty Coal burning plants and right now we are the most polluted in the country with mercury.
Large area lakes in East Texas are already shut down already to fishing because of contamination with Mercury. We do not want Lake Texoma to be contaminated. TXU’s response is “Who said the contamination came from the Mercury produced by the Coal Plant.” Where does the Mercury come from?
“Sullivan reversed strategy and reconvened the hearing. He let all those interested in joining as individuals plead their cases.”
Maybe someone will get the point that the people want to be heard and we want the coal plant project stopped! Governor Perry seems not to be able to visualize that if we live in a polluted state no one will want to live here. TXU will not have a problem because they will sell the excess electricity on the national grid.
We the residents of Texas will suffer and the government will say it made a mistake. We have heard that before, haven’t we?
Dr. Feld,
TXU is using the same arguments against considering the cleaner IGCC technology that have been used by all utilities who are hell-bent on getting their conventional coal plants built before they have to face up to tightening air quality regulations that may include limits on CO2 emissions.
The main claims are that IGCC is not reliable and that it costs much more than coventional coal.
We find that the boiler manufacturers, who are enjoying a heyday these days, are providing a lot of the fodder that feeds such arguments. This is quite understandable, as IGCC would cut into their market just when the world is turning back to coal, and large coal-fired steam power plants to meet the growing need for energy.
Regarding the reliability issue, I find it a travesty that those who reject IGCC as unproven and unreliable still refuse to look beyond the US borders for their data. There are several commercial IGCC projects operating in Europe that are exhibiting plant availability levels well above the US national average for conventional coal plants.
Granted, some of these plants are using refinery wastes, such as asphalt, but the difference between using coal and these feedstocks is not that significant from a reliability standpoint. After all, proponents of PC plants will tell you that coal preparation systems are very reliable.
Also, if one looks into the data, including that from the US plants, one will see that most of the past problems with IGCC plants were due to the turbine equipment and not with the gasification system.
Both US plants (Tampa and Wabash) used early versions of the same model gas turbine that had many reliabiiity issues all over the world – not just in the two IGCC plants.
In Europe, an IGCC plant in Spain used another advanced-design gas turbine that also was the cause of most of the plant outage time.
Meanwhile, there are three or four plants in Italy, and one in the Netherlands, that used a more proven gas turbine design and were able to reach very acceptable availability levels within two or three years of operation.
A new IGCC plant in Japan has apparently gotten over its initial “teething problems” in only one year, and is operating quite satisfactorily.
With this experience behind them, there are European and Japanese suppliers, as well as ones in the US, who would supply an IGCC plant, and who would apply lessons learned from these earlier plants to make new ones even better.
In addition, the construction schedule for an IGCC plant should not be any longer than that for a modern PC plant. So it is not clear that IGCC technolgy would have a problem with meeting the real rate of load growth being experienced on the TXU system.
If an IGCC plant can enjoy the same “fast track” permiting process as being allowed for the proposed PC plants, there is no reason why the first plant couldn’t be online in 2011.
As for the other principal argument used against IGCC, that is, its higher cost, the issue today is that costs of large construction projects are escalating so steeply that it seems to be anyone’s guess what these plants will really cost. In other words, if someone claims that IGCC will cost, say, 20% more than PC plants, that is well within the uncertainty seen in current construction estimating.
Besides, we have been seeing some estimates for new PC plants coming in higher than most IGCC plant cost estimates, and they continue to climb.
In this regards, there was a study completed recently by the Electric Power Research Institute (EPRI) that was sponsored by CPS of San Antonio. That study did find IGCC plants to result in higher cost of electricity, but when one looks into its details, we found some questionable underlying design assumptions, as specified by CPS, that were the cause of most of the cost difference.
If EPRI were to do the same study over again, restating these assumptions to put IGCC on a more level playing field, we think that the results would be quite different.
Unfortunately, in the case of TXU, there was no parallel plant cost study performed in order to obtain a fair comparison of the two technologies. In the case of CPS, the study was done post facto, so quite naturally it could be expected to support the decision that was already made to go with conventional coal burning technology.
I’d fear that any similar study done by TXU, perhaps as might be ordered by the courts now looking into their plans for a new fleet of PC plants, would suffer from the same problem.
Apparently there is a third problem with IGCC that is raised by TXU, that being the claim that there are no suppliers who would guarantee an IGCC plant using low rank coals.
I’ve attended several conferences where the gasifier suppliers all say that they have the ability to use such coals in their gasification process – perhaps at some loss of efficiency and economy – as is the case of a PC plant as well. Granted that the case for IGCC is hurt somewhat with the use of poorer coals, but it is not so much for technical reasons as for economic ones.
TXU should be reminded that the demonstration plant that operated for a number of years during the late ’80s and early ’90s at the Dow Chemical facility in Plaqumemine LA operated on a wide range of coals, and mostly on sub-bituminous. The same gasification process is now operating commercially at the Wabash plant in Indiana and is being offered by ConocoPhillips (Houston) who purchased the technology a few years ago.
At the Wabash plant, the gasifier is co-firing coal with petroleum coke, which enhances the performance of the process and greatly improves the economics.
I hope that this information is helpful to you and to those who are urging the use of IGCC instead of perpetuating the use of PC technology which, as you have shown, promises to leave a long legacy of much higher impact on the air quality of central Texas, and on the health of your citizens.
