This may be the beginning of a bright new future for uranium mining in New Mexico. Uranium Resources, Inc., announced that the Mining and Minerals Division of the New Mexico Energy, Minerals and Natural Resources Department granted the company a permit to conduct exploratory drilling in the Ambrosia Lake area, where the company has approximately 2.4 million pounds of mineralized uranium material combined on several sections. The permit allows URI to drill 10 uranium exploratory holes about six miles west of the village of San Mateo.

A geologist with the New Brunswick Mines Branch in Bathurst has taken exception to media articles concerning unsafe levels of radon and uranium in the Harvey area ("Radon dangers aren't that dire," Telegraph-Journal, May 26). He dismisses any suggestion that well water potentially contaminated with radon or uranium poses a health threat, yet provides no evidence to support his assertion. He also suggests that mortality rates in the Harvey area aren't any different that any other place in the province, but doesn't provide any data to support this claim.

I understand Natural Resources Minister Donald Arseneault to say health risks would occur after exposure of "500 hours," a mere 21 days, of being within five feet of a drill sample with just one per cent of uranium.

Ukraine's Cabinet of Ministers has approved a draft agreement with the Russian Federation and Kazakhstan about the joint participation in the International uranium enrichment center in Angarsk, Irkutsk region, Russia.

The U.S. Energy Department on Thursday will discuss how to best move 16 million tons of uranium mill tailings off the banks of the Colorado River in Moab, Utah. The Energy Department's contractor on the job, Energy Solutions, will move the tailings pile to a disposal site near Crescent Junction.

About 350 people attended a meeting on a proposed $2 billion uranium enrichment plant planned by French-owned Areva SA to make fuel for commercial nuclear power reactors. The meeting was held by the federal Nuclear Regulatory Commission to outline its licensing process for the plant, slated to be operating by 2014. In a community that's been home to the Idaho National Laboratory since 1949, many at Wednesday's event said they were eager for the Nuclear Regulatory Commission to allow construction of the proposed plant to be located about 20 miles from Idaho Falls.

The sludge was a mixture of water and fly ash, a residue that is captured in the chimneys of coal-fired power plants. Fly ash is distinguished from bottom ash, which is removed from the bottom of the furnace. Fly ash is mostly made of fine, hollow, glassy particles of silica, the most abundant mineral in the earth's crust, as well as aluminum oxide, iron oxide, and lime, a white crystalline solid that humans have used for thousands of years. When airborne, some of types of silica particles have been found to be potentially harmful to people's lungs. But more worrisome are the trace concentrations of toxic metals - including arsenic, lead, barium, and chromium - that scientists think may damage the liver and nervous system and cause cancer. The ash also contains uranium and thorium, both radioactive elements. Ounce for ounce, fly ash delivers more radiation into the environment than shielded nuclear waste.

# The United States purchases more oil, natural gas, uranium and electricity from Canada than any other country. # Canada's proven oil reserves total 179 billion barrels, of which 173 billion barrels are in oil sands reserves, making Canada second only to Saudi Arabia in global oil reserves. # 99% of Canada's crude oil exports are to U.S. markets. # Energy flows in both directions between the United States and Canada. Our pipeline and transmission systems are highly integrated and our cross-border trade operates nearly seamlessly.

I was going to write about Tom Paine. The upcoming 200th anniversary of his death on June 9 certainly needs to be acknowledged, but if the people of Cumberland County can pull together to prevent the despoiling of their God-given land, they will do more to honor Tom's memory than my feeble words, so I'll defer for now. When coal burns, most of it turns into gas (carbon dioxide), but heavier minerals are left behind in the ash. Therefore, coal ash contains concentrated amounts of toxic metals such as mercury, lead, arsenic and heavy radioactive elements. As I said in an earlier column, Wake Forest University found Emory River arsenic measurements hundreds of time higher than allowable levels after the TVA ash spill. Radioactivity in the ash is over 50 percent above allowable levels in uranium mining waste.

In the world of renewables, most of the attention is on the wind and the sun. Geothermal power just hasn't gotten the same respect. That could be changing, as both the Obama Administration and Silicon Valley are considering the heat under the ground as a potentially huge source of clean, domestic U.S. energy, but recent setbacks are calling into question how much geothermal can contribute. Given the potential benefits, we should be doubling our efforts to make geothermal a viable power source for the U.S. Some background: All thermal power plants use the same basic process. A heat source (burning coal or gas, uranium, concentrated solar energy) is used to turn water into steam, and the energy released turns a turbine that produces electricity. What sets geothermal apart is that the steam comes directly from the ground. Water percolates down through cracks in the ground and is heated to the boiling point by hot rocks underground (in some cases coming back up as a geyser - think Old Faithful), and the resulting steam is drawn up via a well to a turbine.

For years, residents of the tiny lakeside community near Kingston, Tennessee, watched as the local power plant mixed tons of leftover coal ash with water and pumped the heavy mud into a massive pond just up the road. "We never gave it a second thought," says resident Diane Anderson.

But on December 22 the pond collapsed, triggering a billion-gallon mudslide that knocked houses off foundations and roiled into the Emory River. State officials and the Tennessee Valley Authority, the federally funded utility responsible for the spill, scrambled to allay fears, saying that the ash wasn't toxic and that the drinking water was safe. But residents also heard about the litany of harmful substances in the ash, like arsenic and lead, and about studies linking it to cancer.

All presidents indulge in end-of-the-term environmental rule-making, partly to tie up bureaucratic loose ends but mainly to lock in policies that their successor will be hard pressed to reverse. President Bill Clinton's midnight regulations were mostly good, including a rule protecting 60 million acres of national forests from road-building and most commercial development. Not surprisingly, most of President Bush's proposals are not.

This is 4th in a continuing series of articles by Professor Charles Hall of the SUNY College of Environmental Science and Forestry and his students, describing the energy statistic, "EROI" for various fuels.
