WASHINGTON - Today the Department of the Interior, Department of Energy and the Environmental Protection Agency released a joint statement that lays out the agencies’ shared goals for Navajo Generating Station (NGS) and energy production in the region served by NGS.

In the statement, the three agencies agree they will work together to support Arizona and tribal stakeholders in finding ways to produce “clean, affordable and reliable power, affordable and sustainable water supplies, and sustainable economic development, while minimizing negative impacts on those who currently obtain significant benefits from NGS, including tribal nations.”

In addition to identifying shared goals, the statement announces specific activities the agencies intend to take jointly to help achieve those goals. These actions include: 1) creating a long-term DOI-EPA-DOE NGS working group; 2) working with stakeholders to develop an NGS roadmap; 3) committing to complete the second phase of the National Renewable Energy Laboratory’s report on clean, affordable, and sustainable energy options for NGS; and 4) supporting near-term investments that align with long-term clean energy goals.

A copy of the Joint Statement is available at http://epa.gov/air/tribal/pdfs/130103_statement_ngs.pdf.

NGS is a coal-fired power plant located on the Navajo Indian reservation approximately 15 miles from the Grand Canyon and owned partially by the Interior’s Bureau of Reclamation (Reclamation). Power from the facility is distributed to customers in Arizona, California, and Nevada. Reclamation’s share of the power is used to move water to tribal, agricultural, and municipal water users in central Arizona.

The Department of the Interior, the Department of Energy, and the Environmental Protection Agency oversee other federal responsibilities or interests that relate to NGS. These include tribal trust responsibilities, protection of national parks and wilderness areas, visibility and public health protection, and clean energy development.

WASHINGTON – EPA today released for public comment draft risk assessments, for particular uses, on five chemicals found in common household products. The draft risk assessments were developed as part of the agency’s Toxic Substances Control Act (TSCA) Work Plan, which identified common chemicals for review over the coming years to assess any impacts on people’s health and the environment. Following public comment, the agency will seek an independent, scientific peer review of the assessments before beginning to finalize them in the fall of 2013.

“The draft risk assessments released today for public review and comment highlight the agency’s ongoing commitment to ensure the safety of chemicals we encounter in our daily lives,” said James J. Jones, acting assistant administrator of EPA’s Office of Chemical Safety and Pollution Prevention. “The public and scientific peer review will ensure use of the best science to evaluate any impacts of these substances on people’s health and the environment.”

The five assessments address the following chemical uses: methylene chloride or dichloromethane (DCM) and      n-methylpyrrolidone (NMP) in paint stripper products; trichloroethylene (TCE) as a degreaser and a spray-on protective coating; antimony trioxide (ATO) as a synergist in halogenated flame retardants; and 1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8,-hexamethylcyclopenta-[?]-2-benzopyran (HHCB) as a fragrance ingredient in commercial and consumer products. The draft assessments focus either on human health or ecological hazards for specific uses which are subject to regulation under TSCA. Three of the draft risk assessments— DCM, NMP, and TCE— indicate a potential concern for human health under specific exposure scenarios for particular uses. The preliminary assessments for ATO and HHCB indicate a low concern for ecological health.

EPA recommends the public follow product label directions and take precautions that can reduce exposures, such as using the product outside or in an extremely well ventilated area and wearing protective equipment to reduce exposure. If EPA concludes in finalizing the risk assessments that there is a potential for concern, the agency will take action as appropriate to address possible risks.

The draft assessments were undertaken as part of EPA’s efforts to identify chemicals for review under the TSCA Work Plan, which EPA released in March 2012. At that time, EPA identified 83 chemicals as candidates for review over the coming years and outlined the data sources and other information the agency would use in the reviews. This initiative is part of EPA’s comprehensive approach to enhance the current chemicals management program within the limits of existing TSCA authorities. EPA continues to support updating TSCA to strengthen and modernize the law.

WASHINGTON (Coal Geology)- The U.S. Environmental Protection Agency (EPA) today provided an update on its ongoing national study currently underway to better understand any potential impacts of hydraulic fracturing on drinking water resources. Results of the study, which Congress requested EPA to complete, are expected to be released in a draft for public and peer review in 2014. The update provided today outlines work currently underway, including the status of research projects that will inform the final study. It is important to note that while this progress report outlines the framework for the final study, it does not draw conclusions about the potential impacts of hydraulic fracturing on drinking water resources, which will be made in the final study.

As the administration and EPA has made clear, natural gas has a central role to play in our energy future, and this important domestic fuel source has extensive economic, energy security, and environmental benefits. The study EPA is currently undertaking is part of EPA’s focus to ensure that as the Administration continues to work to expand production of this important domestic resource safely and responsibly.

Among the information released today are updates on 18 research projects and details on the agency’s research approach as well as next steps for these ongoing projects and analyses. Today’s update follows the public release, in November 2011, of the agency’s final study plan, which underwent scientific peer review and public comment.

EPA has engaged stakeholders, including industry, to ensure that the study reflects current practices in hydraulic fracturing. EPA continues to request data and information from the public and stakeholders and has put out a formal request for information which can be accessed through the federal register at: https://www.federalregister.gov/articles/2012/11/09/2012-27452/request-for-information-to-inform-hydraulic-fracturing-research-related-to-drinking-water-resources

EPA also expects to release a draft report of results from the study in late 2014. The study has been designated a Highly Influential Scientific Assessment, meaning it will receive the highest level of peer review in accordance with EPA’s peer review handbook before it is finalized. The 2014 draft report will synthesize the results from the ongoing projects together with the scientific literature to answer the study’s main research questions.

EPA’s Science Advisory Board (SAB) is forming a panel of independent experts which will review and provide their individual input on the ongoing study to EPA. The SAB will provide an opportunity for the public to offer comments for consideration by the individual panel members.

Updated rules provide extensive public health protections, cut costs of compliance

WASHINGTON (Coal Geology)– Today, the U.S. Environmental Protection Agency (EPA) finalized changes to Clean Air Act standards for boilers and certain incinerators that will achieve extensive public health protections by slashing toxic air pollution, including mercury and particle pollution, while at the same addressing feedback provided by industry and labor groups, increasing the rule’s flexibility and dramatically reducing costs.  As a result, 99 percent of the approximately 1.5 million boilers in the U.S. are not covered or can meet the new standards by conducting periodic maintenance or regular tune-ups. 

 

The final adjustments to the standards are based on an extensive analysis of data and input from states, environmental groups, industry, lawmakers and the public.  As a result of information gathered through this review, including significant dialogue and meetings with public health groups, industry, and the public, the final rule dramatically cuts the cost of implementation by individual boilers that EPA proposed in 2010. At the same time, these rules will continue to deliver significant public health benefits.  EPA estimates that for every dollar spent to reduce these pollutants, the public will see $13 to $29 in health benefits, including fewer instances of asthma, heart attacks, as well as premature deaths.

 

Today’s rules set numerical emission limits for less than one percent of boilers – those that emit the majority of pollution from this sector.  For these high emitting boilers and incinerators, typically operating at refineries, chemical plants and other industrial facilities, EPA is establishing more targeted emissions limits that protect public health and provide industry with practical, cost-effective options to meet the standards.

 

EPA has also finalized revisions to the Non-Hazardous Secondary Materials Rule to provide clarity on what types of secondary materials are considered non-waste fuels and provide greater flexibility in rule implementation. This final rule classifies a number of secondary materials as categorical non-wastes when used as a fuel and allows for operators to request that EPA identify specific materials through rulemaking as a categorical non-waste fuel.

Particle pollution and other harmful pollutants released by boilers and incinerators can lead to adverse health effects including cancer, heart disease, aggravated asthma and premature death.  In addition, toxic pollutants such as mercury and lead that will be reduced by this rule are linked to developmental disabilities in children. These standards will avoid up to 8,100 premature deaths, prevent 5,100 heart attacks and avert 52,000 asthma attacks per year in 2015.

In a separate EPA action today, to meet a court deadline, the agency issued final amendments to the 2010 clean air standards for the cement manufacturing industry.  The final amendments maintain the significant emission reductions from the 2010 standards, while providing industry additional time to implement the revised rules.  More information:http://www.epa.gov/airquality/cement
