Is Your Power Company Fighting in Court Against Safeguards From Mercury and Toxic Air Pollution?

Last week marked the deadline for lawsuits to challenge EPA’s Mercury and Air Toxics Standards (MATS) for power plants. Senator James Inhofe (R-OK) also got in on the action and officially announced the launch of his Congressional Review Act resolution to void the MATS.

These health standards are a decade overdue, and will for the first time set national limits on toxic air pollution such as mercury, lead, and cancer-causing dioxins. The standards will reduce by 90% the mercury pollution that coal- and oil-burning power plants emit. Mercury is a dangerous neurotoxin that harms children’s developing brains and nervous systems, and power plants are the largest industrial source of mercury in the United States. Some of the more than 60 other toxic air pollutants emitted by power plants are known or suspected carcinogens, and EPA is finally taking action [pdf] to clean up this pollution.

In addition to significantly reduced neurotoxins and carcinogens, EPA projects [pdf] that starting in 2016, the Mercury and Air Toxics Standards every year will prevent: up to 11,000 premature deaths; nearly 5,000 heart attacks; 130,000 asthma attacks; 5,700 hospital and emergency room visits; and 540,000 days when people miss work and school.

Electric power companies across the country have unleashed their lawyers and lobbyists in Washington, attacking these important health standards in court and in Congress. But many of these companies don’t want to be open about their attacks on important public health safeguards. These corporations hide behind specially created, blandly titled coalitions, which frequently serve as litigious mercenaries fighting clean air safeguards. Using a front group of convenience allows individual electric utility companies to shield their names and anti-public health crusades from public awareness.

* The “Utility Air Regulatory Group,” or UARG, is a challenger in both the Cross State Air Pollution Rule and MATS litigation. As you can see, many of the companies involved in the MATS litigation are members of UARG.

If you Google UARG, there’s no link to the organization, like the other companies listed above. The first result that a Google search returns is a link to the law firm of Hunton & Williams’ air practice group. In comments filed regarding the MATS, UARG describes itself as “a voluntary, not-for-profit group of electric utilities, other electric generating companies, and national trade associations. UARG's purpose is to participate on behalf of its members collectively in EPA's rulemakings under the Clean Air Act and other proceedings that affect the interests of electric generators and in related litigation.”

In effect, UARG has long been linked with the private law firm, Hunton & Williams, with little transparency and no obvious independence from its association with the law firm. This allows power companies to advocate for more pollution and weaker clean air standards through lobbying, litigation, and administrative rulemaking processes, hiding behind UARG's name. In fact, one must wonder whether one reason for UARG's creation was to shield the names of member companies from general public awareness when UARG advocates for dirtier results on the companies' behalf. The litigious efforts of UARG have resulted in numerous lawsuits to weaken, delay or nullify environmental and public health standards affecting the electric power sector.

In a recent Clean Air Act enforcement case [pdf] in the Middle District of North Carolina, UARG and one of its members, Duke Energy, argued that all of the communications among member companies and UARG should be considered privileged attorney-client information protected from disclosure in the litigation. The court rejected the notion that it should “treat the UARG as if it were a corporation so that all communications among members” would be privileged. (p. 25) Further, the court noted that UARG’s “approximately fifty members” (15) banding together “for a common purpose of making their will known to government regulators” (49) didn’t make the information privileged, and UARG was required to disclose the documents to the court.

Even though you might want to know if your local power company has joined federal litigation opposing the first-ever national standards for mercury and other toxic air pollution, you cannot always be sure. Groups like UARG make it possible for power companies to say one thing while their lawyers do another, and customers and the public don't know about this.

However, on rare occasions, the membership of UARG has slipped out. The last time we are aware this happened was in 2006, when UARG disclosed its members when it submitted comments to EPA.

The list above is drawn from that 2006 list. If this list does not reflect UARG's current membership, I invite representatives for UARG or any power companies that are incorrectly listed here to contact me, and I will remove the company's name from this post.

Or, if a company does not support the lawsuits to void EPA’s life-saving Mercury and Air Toxics Standards, but is listed here by virtue of its membership in one of the litigating organizations, I invite those company’s representatives to publicly disavow the lawsuits.

It’s time for power companies to own up to their harmful air pollution and destructive legal tactics to prolong that pollution.

I’m going to call my local power company and ask them if they are a member of UARG. I'll ask if they are fighting in court to overturn the Mercury and Air Toxics Standards and keep poisoning my community’s air. I suggest you do so too.
