The Environmental Protection Agency’s proposed ozone rule–reducing acceptable ground-level ozone from 75 ppb to between 65 and 70–has drawn criticism from 22 medically trained members of Congress (E&E Greenwire, behind paywall:
In a letter to EPA Administrator Gina McCarthy, the 22 Republican members of the House and Senate raised questions about the analysis underlying EPA’s conclusions about the public health benefits of a lower ozone limit.
EPA in November proposed to tighten the national ambient air quality standard for ozone from 75 parts per billion — last set in 2008 during the George W. Bush administration — to between 65 and 70 ppb after finding that the 75 ppb limit was no longer adequate to protect public health.
“As healthcare professionals, we rely upon the most accurate health data,” the group of lawmakers wrote. “From this vantage, we believe that the proposal’s harms outweigh its claimed benefits and are concerned it could ultimately undermine our constituents’ health.”
Of the lawmakers signing the letter, 13 have doctor of medicine degrees. Some of the other signatories have been trained as dentists or eye doctors. Two are registered nurses. Sen. Bill Cassidy (R-La.), who has a doctor of medicine degree, led the effort.
From the letter to McCarthy:
Studies show that income is a key factor in public health, a link confirmed by our first-hand experience as medical professionals caring for patients, including the low income and uninsured. As well, stakeholders have noted serious questions regarding the health benefits EPA claims to support the proposal, and we are concerned that the uncertain benefits asserted by EPA in its ozone proposal will be overshadowed by its harm to the economy and human health. In light of the long-term continuing trend towards cleaner air, as well as ongoing work by states toward further improvements under existing regulations, we encourage EPA to protect American jobs, the economy, and public health by maintaining the existing ozone NAAQS [National Ambient Air Quality Standards].
The letter, citing a study from the National Association of Manufacturers, points out that at a 65 ppb threshold for ozone, rural areas like Yellowstone and the Grand Canyon National Parks would fall into “non-attainment” of the new standard, and as much as over half the entire nation. This would lead, naturally, to job loss and economic turmoil, “making the proposal the most expensive regulation in U.S. history.”
Oil and gas development a boon to one Colorado community, whether or not the company’s investment pans out:
DE BEQUE — A natural gas project by Black Hills Exploration & Production in the De Beque area is involving some upfront investment risks by the company, but with the potential of large rewards for not only Black Hills but the region’s economy and tax base.
Whatever happens, the investment already is paying off for local farmers and ranchers, thanks to a pipeline and water pump station project that officials celebrated the completion of Friday. Black Hills paid for the $8 million project to help supply water for its hydraulic fracturing of wells, but most of the water will be used for irrigation, including by the town, which will reduce De Beque’s need to exercise its senior water rights at the expense of area ranchers.
The water project is an upfront investment that won’t fully pay off for Black Hills unless its De Beque drilling project proceeds to the development phase. But John Benton, vice president and general manager of Black Hills E&P, likes the fact that the company has built something of such value to the De Beque area no matter how its drilling project pans out.
“Regardless of whether we go forward or not with our program, it’s created something that will benefit the community for years to come,” he said.
If the project proceeds, Mesa County could see not only more jobs but an increased tax base.
Not all Colorado communities are filled with activists seeking to ban or otherwise hinder oil and gas development in their back yard:
A few years after a series of anti-oil-and-gas ordinances and ballot initiatives cascaded through several towns in Colorado, some local governments are speaking up in favor of the state’s multibillion-dollar energy industry.
In the last few months, trustees in the tiny town of Platteville in Weld County and commissioners from counties near Denver have signed letters and passed resolutions that speak in favor of the industry and its high-paying jobs.
“If there’s someone who comes in and wants to ban fracking, at that time we’ll vote on it,” Bonnie Dunston, Platteville’s mayor, told the Denver Business Journal.
“But we’re not going to ban fracking. Oil and gas does a lot for us, for our town, our community, and we’re just saying that we’re going to keep oil and gas going here in Platteville,” she said.
Douglas, Arapahoe, and Jefferson county officials have all recently either affirmed support for responsible development within the oil and gas industry or indicated their opposition to bans of any kind, according to DBJ. The officials noted that, while the counties did not see as much direct involvement within their borders compared to places like Weld County, many of their residents worked within the industry.

Earlier this week Todd Shepherd of Complete Colorado reported that before thin-filmed cadmium-telluride solar panel manufacturer Abound Solar declared bankruptcy it was the subject of a Colorado Department of Public Health and Environment (CDPHE) investigation after an anonymous tip raised concerns about cadmium contamination.
Shepherd provided documents showing that the now abandoned Weld County plant produced monthly 630 pounds of highly toxic cadmium waste that was shipped to Deer Trail in Arapahoe County for storage.
Because of the recent interest in cadmium, below is a primer on the rare earth element used in so many products besides solar panels.
Cadmium, one of the 17 rare earth elements (REE), is a soft silver-grey metal, commonly found in ores containing zinc. Products that use significant cadmium include rechargeable batteries, solar cells and protective steel coatings. Recently cadmium has been priced about a dollar per pound.
Cadmium is a byproduct when zinc is refined from zinc ore, or recycled from nickel-cadmium rechargeable batteries. The largest producers of cadmium are China, South Korea, Japan and North America. The concentration of cadmium in the earth’s crust is between 0.1 and 0.5 parts per million (ppm). This is about one hundred times more common than gold.
Cadmium is very useful in rechargeable batteries and solar cells. In the U.S., about 27 percent of cadmium-nickel batteries are recycled, which requires batteries to be taken apart.
However, cadmium is also very poisonous. Exposure is most dangerous when breathing in dust or vapors containing cadmium. Other methods of exposure are also dangerous, as cadmium can be absorbed through the skin or by ingestion.
People can absorb cadmium through inhalation, absorption or by eating it. The cadmium is transported through the body by blood cells and plasma. Cadmium goes into the kidneys, resulting in kidney failure. Before toxic levels are reached, kidney function will start to deteriorate. Generally a third to half of the cadmium that is in a body will be found in the kidneys. Cadmium will also move to the liver and muscles. In the liver, the half-life of the cadmium is 5-15 years, in the muscles-30 years and in the kidneys 10-30 years.
During ore smelting processes, cadmium is released into the air. It may also be released into the atmosphere by burning cadmium-containing garbage. Cadmium exposure can cause throat and lung irritation. Lower levels of exposure also cause shortness of breath, and with prolonged exposure resulting in bronchiolitis and emphysema with lung damage, bloody coughing, and accumulation of fluids in the body. One highly concentrated exposure can cause lifetime damage to lungs. 
Metal fume fever can be caused by inhaling cadmium during the welding and metal heating processes of older silver solder. Metal fume fever can cause flu like symptoms with fainting, sore throats, coughs, and headaches. Working with cadmium requires extremely well ventilated areas, respirators, and extreme care. Regular blood and urine checks are required to monitor the amount of cadmium that can get into the body. 
Phosphate fertilizers, sewage sludge and contaminated water can deposit cadmium into food sources. Growing rice and wheat can absorb Cadmium. Large ocean fish can also take up a lot of cadmium. Smokers also intake cadmium into their bodies and have about double the cadmium levels that non-smokers have. Cadmium is associated with breast cancer, lung cancer, prostate cancer, heart disease, and kidney dysfunction. 
As a result of the increased awareness of the danger of cadmium to humans, the EPA released a new report December 3, 2012, expanding the regulations and proposing new regulations regarding cadmium.
This final rule requires manufacturers (including importers) of cadmium or cadmium compounds, including as part of an article, that have been, or are reasonably likely to be, incorporated into consumer products to report certain unpublished health and safety studies to EPA. 
Occupational Safety Health Association (OSHA) also highly regulates workers contact with cadmium stating,
Cadmium and its compounds are highly toxic and exposure to this metal is known to cause cancer and targets the body’s cardiovascular, renal, gastrointestinal, neurological, reproductive, and respiratory systems.
Requirements to protect workers from cadmium exposure are addressed in specific OSHA cadmium standards covering general industry (1910.1027), shipyards (1915.1027), construction (1926.1127) and agriculture (1928.1027).
In conclusion, Cadmium is critical to the solar cell and rechargeable battery industry but extreme care must be taken to prevent cadmium from getting into the air, water or plant life. Cancer, lung damage and kidney failure are real risks for cadmium exposure.
