Lots of SOx and NOx

On March 26, 2007 the U.S. House of Representatives passed the Maritime Pollution Prevention Act of 2007, giving authority to the US Coast Guard and the EPA to establish and enforce emission limits on domestic and foreign ships entering U.S. waters. Passing 359 to 48, the bill would bring the US into compliance with regulations already used by other countries and adopted by the International Maritime Organization in 1997 to limit emissions of sulfur dioxide (a main component of SOx) and nitrogen oxide (NOx).

Pollutants such as SOx and NOx deplete the environment’s ozone layer, contribute to global warming, effect climate change and have a serious impact on health.

According to a report issued by The International Council on Clean Transportation entitled, “Air Pollution and Greenhouse Gas Emissions from Ocean-going Ships: Impacts, Mitigation Options and Opportunities for Managing Growth,” marine fuel contains a much higher sulfur content than highway diesel fuel. (Recent regulations have forced a substantial decrease in sulfur content for diesel fuel available throughout the United States, resulting in the use of Ultra-Low Sulfur Diesel for on- and off-highway vehicles, thereby lowing SOx emissions.) The report states that ocean-going ships produce more sulfur dioxide than all of the cars, trucks and buses in the world combine.

The latest major action on the bill was on March 28th as it was referred to the Senate Committee on Commerce, Science, and Transportation.

Legal Action Filed to Halt 'Fast-Tracking' of Texas Coal-Fired Power Plants

Major New Challenge to Governor's Attempt to Short-Circuit Full Public Review of Health, Environmental, and Pollution Control Issues in the Permitting Process

AUSTIN, Texas, Dec. 27 -- The Sierra Club, represented by the Austin office of Environmental Integrity Project (EIP), took legal action today to stop the "unprecedented, unreasonable, and ...illegal" plan by Governor Rick Perry to "fast track" administrative hearings for construction of up to 18 dirty coal-fired power plants in the state. Most of the plants in question are being proposed by the Dallas-based utility giant TXU.

EIP Austin Office Counsel Ilan Levin filed the petition on behalf of the Sierra Club to intervene in a state district lawsuit originally brought by Environmental Defense over the processing of coal plant permits. Today's legal action by Sierra Club stems from a recent state agency decision to consolidate six proposed TXU coal plant permits into one hearing, and to set those permits for a speedy decision. The lawsuit seeks to halt Perry's controversial executive order of October 27, 2005, directing the Texas Commission on Environmental Quality (TCEQ) to accelerate consideration of permit applications and the Texas State Office of Administrative Hearings (SOAH) to issue unusually fast decisions on air pollution permits for new electric power plants.

EIP Austin Office Counsel Ilan Levin said: "Today, Sierra Club is asking a judge to overturn a Governor's executive order that imposes unfair burdens on regular people simply trying to avail themselves of the common-sense environmental protections built into state and federal laws. We're saying that speeding up the required decision process for major new sources of smog and other air pollution is illegal and unfair, especially to citizens trying to participate."

Rita Beving, Conservation Co-Chair for the Dallas Sierra Club Group, whose area's air quality would be impacted by coal plant emissions, said: "This legal action is a critical step in the fight by Texas citizens to assert their rights to protect their health and environment from an ill-considered rush to permit these polluting coal-fired power plants, whether we need them or not. The tragedy is that we could meet our energy needs through greater efficiency and renewable energy, without subjecting our cities to further air pollution from coal plants."

The lawsuit notes: "The executive order imposes an unreasonable schedule to thoroughly develop the required technical and legal issues for one major air permit of the type being considered, let alone six of them ... The Governor's Executive Order RP 49 infringes on the rights of Texas citizens to participate meaningfully in the environmental permitting arena.

The right of any affected party to participate in agency permitting decisions is rooted in the constitutional right to due process. The Governor lacks authority to unilaterally alter this system. Further, the Governor lacks the authority to dictate to an administrative law judge exactly how much time is allowed for a judicial administrative decision, and to do so violates the doctrine of separation of powers."

The Perry fast-tracking scheme has huge consequences. The Sierra Club petition notes: "To put the magnitude of the six TXU permits in context, it is worth noting the additional greenhouse gases associated with these new coal plants. While not addressed in the permits, the new units will emit an additional estimated 51 million tons of carbon dioxide per year into Texas skies. In 2005, all existing Texas power plants emitted 255.4 million tons of carbon dioxide."

The Sierra Club contends that a full and deliberate hearing process on each of the power plant applications is crucial due to the serious health and environmental consequences associated with coal-fired power plants, such as increased sulfur dioxide, nitrogen oxides and mercury pollution.

For example, the legal filing points out: "Sulfur dioxide ... interacts with nitrogen oxides to form nitric and sulfuric acids, commonly known as acid rain, which damages forests and acidifies soil and waterways. Harvard School of Public Health studies have shown that SO2 emissions from power plants significantly harm the cardiovascular and respiratory health of people who live near the plants. According to U.S. EPA studies, fine particle pollution from power plants causes more than 20,000 premature deaths a year."

On the topic of mercury pollution, the EIP/Sierra Club petition notes: "Coal-fired power plants are the single largest source of mercury air pollution, accounting for roughly 40 percent of all mercury emissions nationwide. Mercury is a highly toxic metal that, once released into the atmosphere, settles in lakes and rivers, where it moves up the food chain to humans. The Centers for Disease Control has found that roughly 10 percent of American women carry mercury concentrations at levels considered to put a fetus at risk of neurological damage."

Another major pollutant -- nitrogen oxide -- is a major contributor to ozone smog-forming pollution, which has been a major problem for ambient air quality in the Dallas/Fort Worth and Austin areas.

Usually each power plant application would be considered separately with a full review of the risks associated with its additional pollution impact. The new plants also would be examined to verify that that are using the best available technology in order to not degrade air quality.

ABOUT THE GROUPS
Sierra Club is one of the oldest and largest grassroots environmental organizations in the country. The Club has more than 700,000 members nationwide, and roughly 23,000 Texas members. The Sierra Club is dedicated to preserving and enhancing the natural environment and protecting public health, among other goals. The Sierra Club has the specific goal of improving outdoor air quality. The Sierra Club is a party in administrative proceedings that are at issue in this litigation.

With offices in Washington, D.C. and Austin, Texas, the Environmental Integrity Project (http://www.environmentalintegrity.org/) is a nonpartisan, nonprofit organization established in March of 2002 to advocate for more effective enforcement of environmental laws. EIP was founded by Eric Schaeffer, who was director of the U.S. Environmental Protection Agency's Office of Regulatory Enforcement. He resigned in 2002 after publicly expressing his frustration with efforts of the Bush Administration to weaken enforcement of the Clean Air Act and other laws.

From the report executive summary: The Acid Rain Program was created to implement Title IV of the 1990 Clean Air Act Amendments. The purpose of Title IV is to reduce the adverse effects of acid deposition through reductions in annual emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) by 10 million tons and by 2 million tons below projected levels, respectively.

Sulfur dioxide (SO2) and nitrogen oxides (NOx) are the key pollutants in the formation of acid rain. These pollutants also contribute to the formation of fine particles (sulfates and nitrates) that are associated with significant human health effects and regional haze. Additionally, NOx combines with volatile organic compounds (VOCs) to form ground-level ozone (smog) and nitrates that are transported and deposited at environmentally detrimental levels in parts of the country. These pollutants, in their various forms, lead to the acidification of lakes and streams rendering some of them incapable of supporting aquatic life. In addition, they impair visibility in our national parks, create respiratory and other health problems in people, weaken forests, and degrade monuments and buildings.

In the United States, the electric power industry accounts for approximately 67 percent of total annual SO2 emissions and slightly more than 20 percent of total annual NOx emissions.

Since the start of the Acid Rain Program in 1995, the lower SO2 and NOx emission levels from the power sector have contributed to significant air quality and environmental and human health improvements.

Since its inception, the Acid Rain Program has:

- Reduced SO2 emissions by over 5.5 million tons from 1990 levels, or about 35 percent of total emissions from the power sector. Compared to 1980 levels, SO2 emissions from power plants have dropped by more than 7 million tons, or about 41 percent.
- Cut NOx emissions by about 3 million tons from 1990 levels, so that emissions in 2005 were less than half the level anticipated without the program. Other efforts, such as the NOx Budget - Trading Program in the eastern United States, also contributed significantly to this reduction.
Led to significant cuts in acid deposition, including reductions in sulfate deposition of about 36 percent in some regions of the United States and improvements in environmental indicators, such as fewer acidic lakes.
- Provided the most complete and accurate emission data ever developed under a federal air pollution control program and made that data available and accessible by using comprehensive electronic data reporting and Web-based tools for agencies, researchers, affected sources, and the public.
- Served as a leader in delivering e-government, automating administrative processes, reducing paper use, and providing online systems for doing business with EPA.
- Resulted in nearly 100 percent compliance through rigorous emissions monitoring, allowance tracking, and an automatic, easily understood penalty system for noncompliance. Flexibility in compliance strategies reduced implementation costs.

A 2005 study (PDF 532 KB; 15 pp) estimates that in 2010, the Acid Rain Program's annual benefits will be approximately $122 billion (2000$), at an annual cost of about $3 billion - a 40-to-1 benefit-to-cost ratio.

The Acid Rain Program 2005 Progress Report includes special sections on fuel switching and compliance options, EPA's framework for accountability, program costs and benefits, surface water quality monitoring, impact assessment, environmental justice, and the Clean Air Rules. Building on the Acid Rain Program model, EPA promulgated the Clean Air Interstate Rule (CAIR), to address transport of fine particles and ozone in the eastern United States, the Clean Air Mercury Rule (CAMR) to reduce nationwide mercury emissions from power plants, and the Clean Air Visibility Rule (CAVR) to improve visibility in national parks and wilderness areas.
