Regulatory and Technical Issues Concerning the Detection and Treatment of NDMA-Contaminated Groundwater at NASA WSTF

NASA Technical Reports Server (NTRS)

Wiebe, D. T.; Zigmond, M. J.; Tufts, C. A.

2002-01-01

The National Aeronautics and Space Administration (NASA) White Sands Test Facility (WSTF) was established in 1963 primarily to provide rocket engine testing services for several NASA programs. The groundwater underlying the site has been contaminated as a result of historical operations. Groundwater contaminants include several volatile organic compounds (VOCs) and two semi-volatile compounds: N-nitrosodimethylamine (NDMA) and N-nitrodimethylamine (DMN). This paper discusses some of the technical, analytical, regulatory, and health risk issues associated with the contaminant plume. The plume has moved approximately 2.5 miles downgradient of the facility industrial boundary, with evidence of continued migration. As a result, NASA has proposed a pump and treat system using air strippers and ultraviolet (UV) oxidation to stabilize future movement of the contaminant plume. The system has been designed to treat 1,076 gallons (4,073 liters) per minute, with provisions for future expansion. The UV oxidation process was selected to treat NDMA-contaminated groundwater based on successes at other NDMA-contaminated sites. Bench- and pilot-scale testing of WSTF groundwater confirmed the ability of UV oxidation to destroy NDMA and generated sufficient data to design the proposed full-scale treatment system. NDMA is acutely toxic and is a probable human carcinogen. EPA-recommended health risk criteria for the residential consumption of NDMA/DMN-contaminated groundwater was used to determine that a 1.0 x 10(exp -6) excess cancer risk corresponds to 1.7 parts per trillion (ppt). EPA analytical methods are unable to detect NDMA and DMN in the low ppt range. EPA's current Appendix IX analytical method used to screen for NDMA, Method 8270, can detect NDMA only at levels that are orders of magnitude greater than the recommended health risk level. Additionally, EPA Method 607, the most sensitive EPA approved method, has a detection limit of 150 ppt. This corresponds to an excess cancer risk of 9.0 x 10(exp -5), which exceeds the State of New Mexico's water quality standard of a cancer risk less than 1 x 10(exp -5). The treatment system has been engineered to treat contaminated groundwater to levels significantly below the New Mexico standard. However, the inability of EPA-approved analytical methods to detect NDMA and DMN at low ppt levels, and to provide verification of compliance with the 1 x 10(exp -5) cancer risk, introduces a notable risk to the long-term operation of the system. WSTF has been working with Southwest Research Institute to develop a non-EPA analytical method that can achieve a reporting limit of 1 ppt, which corresponds to an excess cancer risk of 7.6 x 10(exp -7). WSTF is currently developing a proposal to obtain approval from the New Mexico Environment Department (NMED) of this non-EPA method.

...EPA is issuing a supplement to its proposed approval of the State of Indiana's request to redesignate the Indianapolis area to attainment for the 1997 annual National Ambient Air Quality Standards (NAAQS or standard) for fine particulate matter (PM2.5). This supplemental proposal revises and expands the basis for proposing approval of the state's request, in light of developments since EPA issued its initial proposal on September 27, 2011. This supplemental proposal addresses four issues, including the effects of two decisions of the United States Court of Appeals for the District of Columbia (D.C. Circuit or Court): the Court's August 21, 2012 decision to vacate and remand to EPA the Cross- State Air Pollution Control Rule (CSAPR) and the Court's January 4, 2013 decision to remand to EPA two final rules implementing the 1997 PM2.5 standard. In this supplemental proposal, EPA is also proposing to approve a supplement to the emission inventories previously submitted by the state. EPA is proposing that the inventories for ammonia and Volatile Organic Compounds (VOC), in conjunction with the inventories for nitrogen oxides (NOX), direct PM2.5, and sulfur dioxide (SO2) that EPA previously proposed to approve, meet the comprehensive emissions inventory requirement of the Clean Air Act (CAA). Finally, this supplemental proposal solicits comment on the state's January 17, 2013 submission of Motor Vehicle Emissions Budgets (MVEBs) developed using EPA's Motor Vehicle Emissions Simulator (MOVES) 2010a emissions model to replace the MOBILE6.2 based MVEBs previously submitted as part of the PM2.5 maintenance plan for the Indianapolis area. EPA is seeking comment only on the issues raised in its supplemental proposal, and is not re-opening for comment other issues raised in its prior proposal.

US Department of Energy response to standards for remedial actions at inactive uranium processing sites: Proposed rule

1988-01-29

The Title I groundwater standards for inactive uranium mill tailings sites, which were promulgated on January 5, 1983, by the US Environmental Protection Agency (EPA) for the Uranium Mill Tailings Remedial Action (UMTRA) Project, were remanded to the EPA on September 3, 1985, by the US Tenth Circuit Court of Appeals. The Court instructed the EPA to compile general groundwater standards for all Title I sites. On September 24, 1987, the EPA published proposed standards (52FR36000-36008) in response to the remand. This report includes an evaluation of the potential effects of the proposed EPA groundwater standards on the UMTRA Project,more » as well as a discussion of the DOE's position on the proposed standards. The report also contains and appendix which provides supporting information and cost analyses. In order to assess the impacts of the proposed EPA standards, this report summarizes the proposed EPA standards in Section 2.0. The next three sections assess the impacts of the three parts of the EPA standards: Subpart A considers disposal sites; Subpart B is concerned with restoration at processing sites; and Subpart C addresses supplemental standards. Section 6.0 integrates previous sections into a recommendations section. Section 7.0 contains the DOE response to questions posed by the EPA in the preamble to the proposed standards. 6 refs., 5 figs., 3 tabs.« less

...EPA is proposing to approve revisions to the SIP for the State of Texas that relate to antibacksliding of Major NSR SIP Requirements for the one-hour ozone NAAQS; Major NNSR SIP requirements for the 1997 eight-hour ozone NAAQS; Major NSR Reform Program with Plantwide Applicability Limit (PAL) provisions; and non-PAL aspects of the Major NSR SIP requirements. EPA proposes to find that these changes to the Texas SIP comply with the Federal Clean Air Act (the Act or CAA) and EPA regulations and are consistent with EPA policies. Texas submitted revisions to these programs on June 10, 2005, and February 1, 2006. EPA disapproved these SIP revisions on September 15, 2010 (75 FR 56424). In response to the 2010 disapproval, Texas submitted revisions to these programs in two separate SIP submittals on March 11, 2011. These SIP submittals include resubmittal of the rules that were previously submitted June 10, 2005, and February 1, 2006, and subsequently disapproved by EPA on September 15, 2010. On February 22, 2012, Texas proposed further revisions to the NSR Reform Program to further clarify and ensure compliance with Federal requirements relating to NSR Reform. On May 3, 2012, Texas provided a letter to EPA which requested that EPA parallel process the revisions proposed February 22, 2012, and included a demonstration showing how its submitted rules are at least as stringent as the Federal NSR Reform Program. Texas has requested that EPA parallel process the revisions proposed February 22, 2012, and consider the May 3, 2012, letter in the review of the March 11, 2011, SIP submittals. Today, EPA is proposing to find that the March 11, 2011, SIP submittals; the February 22, 2012, proposed revisions; and the May 3, 2012, letter, address each of the grounds for EPA's September 15, 2010, disapproval and other issues related to the Texas NSR Reform revisions as identified later. Accordingly, EPA proposes to approve these two March 11, 2011, revisions; the February 22, 2012, proposed revisions for which Texas has requested parallel processing; and the May 3, 2012, letter as part of the Texas NSR SIP. EPA is proposing this action under section 110 and parts C and D of the Act.

...The Environmental Protection Agency (EPA or Agency) is proposing to regulate for the first time, coal combustion residuals (CCRs) under the Resource Conservation and Recovery Act (RCRA) to address the risks from the disposal of CCRs generated from the combustion of coal at electric utilities and independent power producers. However, the Agency is considering two options in this proposal and, thus, is proposing two alternative regulations. Under the first proposal, EPA would reverse its August 1993 and May 2000 Bevill Regulatory Determinations regarding coal combustion residuals (CCRs) and list these residuals as special wastes subject to regulation under subtitle C of RCRA, when they are destined for disposal in landfills or surface impoundments. Under the second proposal, EPA would leave the Bevill determination in place and regulate disposal of such materials under subtitle D of RCRA by issuing national minimum criteria. Under both alternatives EPA is proposing to establish dam safety requirements to address the structural integrity of surface impoundments to prevent catastrophic releases. EPA is not proposing to change the May 2000 Regulatory Determination for beneficially used CCRs, which are currently exempt from the hazardous waste regulations under Section 3001(b)(3)(A) of RCRA. However, EPA is clarifying this determination and seeking comment on potential refinements for certain beneficial uses. EPA is also not proposing to address the placement of CCRs in mines, or non-minefill uses of CCRs at coal mine sites in this action.

...EPA proposed on April 25, 2012 (77 FR 24794) to take action on a revision to the state implementation plan (SIP) addressing regional haze submitted by the State of New York. In that proposal, EPA proposed to address through a Federal Implementation Plan (FIP) certain requirements not addressed in New York's regional haze SIP submission or, alternatively, to approve a substantively identical SIP revision by New York, should the State timely submit such a revision. In two letters dated April 16, 2012, New York submitted additional materials relevant to our proposed action on its regional haze SIP submission, including proposed SIP revisions addressing the requirements for best available retrofit technology controls (BART) for a number of sources. EPA is providing notice of availability of these materials. The comment period on EPA's proposed action on the New York regional haze SIP closes on June 18, 2010.

...EPA is proposing to approve in part and disapprove in part state implementation plan (SIP) revisions submitted by California to provide for attainment of the 1997 annual and 24-hour fine particulate matter (PM2.5) national ambient air quality standards (NAAQS) in the San Joaquin Valley (SJV) nonattainment area. The SIP revisions are the SJV 2008 PM2.5 Plan (revised 2010) and portions of the 2007 State Strategy (revised 2009). Specifically, EPA is proposing to approve the emissions inventories as meeting the requirements of the Clean Air Act and EPA's fine particle implementing rule and to approve commitments to implement specific measures and meet specific aggregate emissions reductions by the San Joaquin Valley Air Pollution Control District and the California Air Resource Board. In addition, we are proposing to find that volatile organic compounds are a PM2.5 attainment plan precursor in the SJV for which controls should be evaluated. EPA is proposing to disapprove the attainment demonstration. EPA is also proposing to disapprove the reasonably available control measures/reasonably available control technology demonstration, the air quality modeling, the reasonable further progress (RFP) demonstration, the contingency measures, and the attainment and RFP conformity motor vehicle emissions budgets. EPA is also proposing to not grant California's request to extend to April 5, 2015 the deadline for the SJV nonattainment area to attain the 1997 PM2.5 NAAQS.

Federal Register 2010, 2011, 2012, 2013, 2014

2010-11-30

...EPA and NHTSA, on behalf of the Department of Transportation, are each proposing rules to establish a comprehensive Heavy-Duty National Program that will reduce greenhouse gas emissions and increase fuel efficiency for on-road heavy-duty vehicles, responding to the President's directive on May 21, 2010, to take coordinated steps to produce a new generation of clean vehicles. NHTSA's proposed fuel consumption standards and EPA's proposed carbon dioxide (CO2) emissions standards would be tailored to each of three regulatory categories of heavy-duty vehicles: Combination Tractors; Heavy-Duty Pickup Trucks and Vans; and Vocational Vehicles, as well as gasoline and diesel heavy-duty engines. EPA's proposed hydrofluorocarbon emissions standards would apply to air conditioning systems in tractors, pickup trucks, and vans, and EPA's proposed nitrous oxide (N2O) and methane (CH4) emissions standards would apply to all heavy-duty engines, pickup trucks, and vans. EPA is also requesting comment on possible alternative CO2-equivalent approaches for model year 2012-14 light-duty vehicles. EPA's proposed greenhouse gas emission standards under the Clean Air Act would begin with model year 2014. NHTSA's proposed fuel consumption standards under the Energy Independence and Security Act of 2007 would be voluntary in model years 2014 and 2015, becoming mandatory with model year 2016 for most regulatory categories. Commercial trailers would not be regulated in this phase of the Heavy- Duty National Program, although there is a discussion of the possibility of future action for trailers.

2010-01-29

...Under section 110(k)(6) of the Clean Air Act, EPA is proposing to correct our May 2004 final approval of revisions to the San Joaquin Valley Unified Air Pollution Control District portion of the California State Implementation Plan. EPA is also proposing to take action on three amended District rules, one of which was submitted on March 7, 2008 and the other two of which were submitted on March 17, 2009. Two of the submitted rules reflect revisions to approved District rules that provide for review of new and modified stationary sources (``new source review'' or NSR) within the District, and the third reflects revisions to an approved District rule that provides a mechanism by which existing stationary sources may be exempt from the requirement to secure a Federally-mandated operating permit. The NSR rule revisions relate to exemptions from permitting and from offsets for certain agricultural operations, to the establishment of NSR applicability and offset thresholds consistent with a classification of ``extreme'' nonattainment for the ozone standard, and to the implementation of EPA's NSR Reform Rules. With respect to the revised District NSR rules, EPA is proposing a limited approval and limited disapproval because, although the changes would strengthen the SIP, there are deficiencies in enforceability that prevent full approval. With respect to the operating permit rule, EPA is proposing a full approval. Lastly, EPA is proposing to rescind certain obsolete permitting requirements from the District portion of the California plan. If EPA were to finalize the limited approval and limited disapproval action, as proposed, then a sanctions clock, and EPA's obligation to promulgate a Federal implementation plan, would be triggered because certain revisions to the District rules that are the subject of this action are required under anti-backsliding principles established for the transition from the 1-hour to the 8-hour ozone standard.

Murphy, William J.; Flamme, Gregory A.; Meinke, Deanna K.; Sondergaard, Jacob; Finan, Donald S.; Lankford, James E.; Khan, Amir; Vernon, Julia; Stewart, Michael

2015-01-01

Objective In 2009, the U.S. Environmental Protection Agency (EPA) proposed an impulse noise reduction rating (NRR) for hearing protection devices based upon the impulse peak insertion loss (IPIL) methods in the ANSI S12.42-2010 standard. This study tests the ANSI S12.42 methods with a range of hearing protection devices measured in field conditions. Design The method utilizes an acoustic test fixture and three ranges for impulse levels: 130–134, 148–152, and 166–170 dB peak SPL. For this study, four different models of hearing protectors were tested: Bilsom 707 Impact II electronic earmuff, E·A·R Pod Express, E·A·R Combat Arms version 4, and the Etymotic Research, Inc. Electronic BlastPLG™ EB1. Study sample Five samples of each protector were fitted on the fixture or inserted in the fixture's ear canal five times for each impulse level. Impulses were generated by a 0.223 caliber rifle. Results The average IPILs increased with peak pressure and ranged between 20 and 38 dB. For some protectors, significant differences were observed across protector examples of the same model, and across insertions. Conclusions The EPA's proposed methods provide consistent and reproducible results. The proposed impulse NRR rating should utilize the minimum and maximum protection percentiles as determined by the ANSI S12.42-2010 methods. PMID:22176308

EPA issues ANPR on significant new uses of lead

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bergeson, L.L.

1994-12-01

The US Environmental Protection Agency (EPA) signed off on an Advance Notice of Proposed Rulemaking (ANPR) for significant new uses of lead. The Significant New Use Rule (SNUR) would require people to notify EPA at least 90 days before commencing the manufacture, import or processing of lead and lead compounds for new uses. Section 5(a) of the Toxic Substances Control Act (TSCA) provides EPA with authority to screen new uses of a chemical substance to determine whether these uses should be regulated. The screening function is accomplished through the SNUR process. EPA may issue a SNUR for chemical substances aftermore » considering relevant factors including: the projected volume of manufacturing and processing of a chemical substance; the extent to which a use changes the type or form of human or environmental exposure to a chemical substance; the extent to which a new use increases the magnitude and duration of a human or environmental exposure to a chemical substance; and the reasonably anticipated manner and methods of manufacturing, processing, distribution in commerce and disposal of the chemical substance.« less

...EPA is proposing to more clearly describe the active and inert ingredients permitted in products eligible for the exemption from regulation for minimum risk pesticides. EPA is proposing to reorganize these lists with a focus on clarity and transparency by adding specific chemical identifiers. The identifiers would make it clearer to manufacturers; the public; and Federal, state, and tribal inspectors which ingredients are permitted in minimum risk pesticide products. EPA is also proposing to modify the label requirements in the exemption to require the use of specific common chemical names in lists of ingredients on minimum risk pesticide product labels, and to require producer contact information on the label. Once final, these proposed changes would maintain the availability of minimum risk pesticide products while providing more consistent information for consumers, clearer regulations for producers, and easier identification by states, tribes and EPA as to whether a product is in compliance with the exemption.

...The Environmental Protection Agency (EPA) is proposing a Federal Implementation Plan (FIP) to address regional haze in the State of Montana. EPA developed this proposal in response to the State's decision in 2006 to not submit a regional haze State Implementation Plan (SIP) revision. EPA is proposing to determine that the FIP satisfies requirements of the Clean Air Act (CAA or ``the Act'') that require states, or EPA in promulgating a FIP, to assure reasonable progress towards the national goal of preventing any future and remedying any existing man-made impairment of visibility in mandatory Class I areas. In addition, EPA is also proposing to approve a revision to the Montana SIP submitted by the State of Montana through the Montana Department of Environmental Quality on February 17, 2012. The State's submittal contains revisions to the Montana Visibility Plan that includes amendments to the ``Smoke Management'' section, which adds a reference to Best Available Control Technology (BACT) as the visibility control measure for open burning as currently administered through the State's air quality permit program. This change was made to meet the requirements of the Regional Haze Rule. EPA will act on the remaining revisions in the State's submittal in a future action.

The Occurrence of 16 EPA PAHs in Food – A Review

PubMed Central

Zelinkova, Zuzana; Wenzl, Thomas

2015-01-01

Occurrence and toxicity of polycyclic aromatic hydrocarbons (PAHs) have been extensively studied in countries all over the world. PAHs generally occur in complex mixtures which may consist of hundreds of compounds. The U.S. Environmental Protection Agency (EPA) proposed in the 1970 to monitor a set of 16 PAHs which are frequently found in environmental samples. This article reviews the suitability of the 16 EPA PAHs for the assessment of potential health threats to humans stemming from the exposure to PAHs by food ingestion. It presents details on analysis methods, the occurrence of PAHs in food, regulatory aspects, and related risk management approaches. In addition, consideration is given to newer evaluations of the toxicity of PAHs and the requirements for risk assessment and management stemming from them. PMID:26681897

This revision addresses the requirements of the Clean Air Act (CAA or Act) and EPA's rules that require states to prevent any future and remedy any existing anthropogenic impairment of visibility in mandatory Class I areas (national parks and wilderness areas) caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ``regional haze program''). States are required to assure reasonable progress towards the national goal of achieving natural visibility conditions in Class I areas. EPA is proposing a limited approval of this SIP revision to implement the regional haze requirements for Alabama on the basis that the revision, as a whole, strengthens the Alabama SIP. Additionally, EPA is proposing to rescind the federal regulations previously approved into the Alabama SIP on November 24, 1987, and to rely on the provisions in Alabama's July 15, 2008, SIP submittal to meet the long-term strategy (LTS) requirements for reasonably attributable visibility impairment (RAVI). EPA has previously proposed a limited disapproval of the Alabama regional haze SIP because of deficiencies in the State's regional haze SIP submittal arising from the remand by the U.S. Court of Appeals for the District of Columbia Circuit (DC Circuit) to EPA of the Clean Air Interstate Rule (CAIR). Consequently, EPA is not proposing to take action in this rulemaking to address the State's reliance on CAIR to meet certain regional haze requirements.

Sediment quality criteria: A review with recommendations for developing criteria for the Hanford Site

DOE Office of Scientific and Technical Information (OSTI.GOV)

Driver, C.J.

1994-05-01

Criteria for determining the quality of liver sediment are necessary to ensure that concentrations of contaminants in aquatic systems are within acceptable limits for the protection of aquatic and human life. Such criteria should facilitate decision-making about remediation, handling, and disposal of contaminants. Several approaches to the development of sediment quality criteria (SQC) have been described and include both descriptive and numerical methods. However, no single method measures all impacts at all times to all organisms (U.S. EPA 1992b). The U.S. EPA`s interest is primarily in establishing chemically based, numerical SQC that are applicable nation-wide (Shea 1988). Of the approachesmore » proposed for SQC development, only three are being considered for numerical SQC on a national level. These approaches include an Equilibrium Partitioning Approach, a site-specific method using bioassays (the Apparent Effects Threshold Approach), and an approach similar to EPA`s water quality criteria (Pavlou and Weston 1984). Although national (or even regional) criteria address a number of political, litigative, and engineering needs, some researchers feel that protection of benthic communities require site-specific, biologically based criteria (Baudo et al. 1990). This is particularly true for areas where complex mixtures of contaminants are present in sediments. Other scientifically valid and accepted procedures for freshwater SQC include a background concentration approach, methods using field or spiked bioassays, a screening level concentration approach, the Apparent Effects Threshold Approach, the Sediment Quality Triad, the International Joint Commission Sediment Assessment Strategy, and the National Status and Trends Program Approach. The various sediment assessment approaches are evaluated for application to the Hanford Reach and recommendations for Hanford Site sediment quality criteria are discussed.« less

Are EPA's proposed revisions to the PM standards appropriate?

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lucinda Minton Langworthy

2006-06-15

In 1997 then-US Environmental Protection Agency (EPA) Administrator Carol Browner adopted new National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM2.5). Browner recognized that 'there is uncertainty in the characterization of health effects attributable to exposure to ambient PM.' As a result, President Clinton promised to review the scientific basis for those standards prior to their implementation. Recently, before EPA has even promulgated rules concerning implementation of those standards, the agency proposed to revise those standards to make them significantly more stringent. Are the proposed revisions to the standards appropriate? The author argues. 41 refs.

Analysis of 70 Environmental Protection Agency priority pharmaceuticals in water by EPA Method 1694.

PubMed

Ferrer, Imma; Zweigenbaum, Jerry A; Thurman, E Michael

2010-09-03

The U.S. Environmental Protection Agency (EPA) Method 1694 for the determination of pharmaceuticals in water recently brought a new challenge for treatment utilities, where pharmaceuticals have been reported in the drinking water of 41-million Americans. This proposed methodology, designed to address this important issue, consists of solid-phase extraction (SPE) followed by liquid chromatography-mass spectrometry (LC/MS-MS) using triple quadrupole. Under the guidelines of Method 1694, a multi-residue method was developed, validated, and applied to wastewater, surface water and drinking water samples for the analysis of 70 pharmaceuticals. Four distinct chromatographic gradients and LC conditions were used according to the polarity and extraction of the different pharmaceuticals. Positive and negative ion electrospray were used with two MRM transitions (a quantifier and a qualifier ion for each compound), which adds extra confirmation not included in the original Method 1694. Finally, we verify, for the first time, EPA Method 1694 on water samples collected in several locations in Colorado, where positive identifications for several pharmaceuticals were found. This study is a valuable indicator of the potential of LC/MS-MS for routine quantitative multi-residue analysis of pharmaceuticals in drinking water and wastewater samples and will make monitoring studies much easier to develop for water utilities across the US, who are currently seeking guidance on analytical methods for pharmaceuticals in their water supplies. 2010 Elsevier B.V.

Assessment of air quality in Haora River basin using fuzzy multiple-attribute decision making techniques.

PubMed

Singh, Ajit Pratap; Chakrabarti, Sumanta; Kumar, Sumit; Singh, Anjaney

2017-08-01

This paper deals with assessment of air quality in Haora River basin using two techniques. Initially, air quality indices were evaluated using a modified EPA method. The indices were also evaluated using a fuzzy comprehensive assessment (FCA) method. The results obtained from the fuzzy comprehensive assessment method were compared to that obtained from the modified EPA method. To illustrate the applicability of the methodology proposed herein, a case study has been presented. Air samples have been collected at 10 sampling sites located along Haora River. Six important air pollutants, namely, carbon monoxide, sulfur dioxide, nitrogen dioxide, suspended particulate matter (SPM), PM 10 , and lead, were monitored continuously, and air quality maps were generated on the GIS platform. Comparison of the methodologies has clearly highlighted superiority and robustness of the fuzzy comprehensive assessment method in determining air quality indices under study. It has effectively addressed the inherent uncertainties involved in the evaluation, modeling, and interpretation of sampling data, which was beyond the scope of the traditional weighted approaches employed otherwise. The FCA method is robust and prepares a credible platform of air quality evaluation and identification, in face of the uncertainties that remain eclipsed in the traditional approaches like the modified EPA method. The insights gained through the present study are believed to be of pivotal significance in guiding the development and implementation of effective environmental remedial action plans in the study area.

First, EPA is proposing to determine that the Area has attained the 1997 annual average PM2.5 National Ambient Air Quality Standard (NAAQS). This proposed determination of attainment is based upon complete, quality- assured and certified ambient air monitoring data for the 2007-2009 period showing that the Area has attained the 1997 annual PM2.5 NAAQS, and data available to date for 2010 in EPA's Air Quality System (AQS) database that show the area continues to attain. If EPA finalizes this proposed determination of attainment, the requirements for the Area to submit attainment demonstrations and associated reasonably available control measures (RACM), a reasonable further progress (RFP) plan, contingency measures, and other planning State Implementation Plan (SIP) revisions related to attainment of the standard shall be suspended for so long as the Area continues to attain the annual PM2.5 NAAQS. Second, EPA is also proposing to determine, based on quality-assured and certified monitoring data for the 2007-2009 monitoring period, that the Area has attained the 1997 annual PM2.5 NAAQS by its applicable attainment date of April 5, 2010.

Tough choices in proposed budget for Environmental Protection Agency

NASA Astrophysics Data System (ADS)

Balcerak, Ernie

2012-03-01

President Obama's proposed budget for the Environmental Protection Agency (EPA) for fiscal year (FY) 2013 is $8.34 billion, a 1.2% decrease from the agency's 2012 enacted budget. "This budget is focused on fulfilling EPA's core mission to protect health and the environment for millions of American families. It demonstrates the fiscal responsibility called for at this moment, while still supporting clean air, healthy waters, and innovative safeguards that are essential to an America built to last," said EPA administrator Lisa Jackson in a 13 February briefing announcing the budget proposal. Balancing tight funding environments with EPA's goals "has required taking a step back from programs we have worked on for years, programs were we have had great success," she said. "There are difficult choices throughout this budget, but they enable us to do what is required for our immediate priorities as well as challenges down the road."

Proposed U.S. Environmental Protection Agency Budget Shows Belt-Tightening

NASA Astrophysics Data System (ADS)

Showstack, Randy

2011-03-01

President Barack Obama's proposed fiscal year (FY) 2012 budget for the Environmental Protection Agency (EPA) is $8.97 billion, a 13% decrease from the agency's FY 2010 enacted budget of $10.3 billion. While Congress has approved a moderate continuing resolution (CR) to fund the federal government until 18 March, the House of Representatives also has passed a CR (House Resolution 1; HR 1) that would call for sharp cuts to the budget for EPA and other agencies for the current fiscal year (2011). EPA administrator Lisa Jackson acknowledged the difficult budget situation during a 14 February teleconference. The proposed budget “reflects the tough choices needed for our nation's short- and long-term fiscal health and allows EPA to maintain its fundamental mission of protecting human health and the environment,” she said. “This budget focuses our resources on the most urgent health and environmental challenges we face. Though it includes significant cuts, it provides EPA with what we need to fundamentally protect the health of the American people,” Jackson added.

This revision addresses the requirements of the Clean Air Act (CAA) and EPA's rules that require states to prevent any future and remedy any existing anthropogenic impairment of visibility in mandatory Class I areas (national parks and wilderness areas) caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ``regional haze program''). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. EPA is proposing a limited approval of this SIP revision to implement the regional haze requirements for North Carolina on the basis that the revision, as a whole, strengthens the North Carolina SIP. In a separate action, EPA has proposed a limited disapproval of the North Carolina regional haze SIP because of deficiencies in the State's regional haze SIP submittal arising from the remand by the U.S. Court of Appeals for the District of Columbia Circuit (DC Circuit) to EPA of the Clean Air Interstate Rule (CAIR). Consequently, EPA is not proposing to take action in this rulemaking to address the State's reliance on CAIR to meet certain regional haze requirements.

...On June 24, 2008, the EPA promulgated amendments to the Standards of Performance for Petroleum Refineries and new standards of performance for petroleum refinery process units constructed, reconstructed or modified after May 14, 2007. The EPA subsequently received three petitions for reconsideration of these final rules. On September 26, 2008, the EPA granted reconsideration and issued a stay for the issues raised in the petitions regarding process heaters and flares. On December 22, 2008, the EPA addressed those specific issues by proposing amendments to certain provisions for process heaters and flares and extending the stay of these provisions until further notice. The EPA also proposed technical corrections to the rules for issues that were raised in the petitions for reconsideration. In this action, the EPA is finalizing those amendments and technical corrections and is lifting the stay of all the provisions granted on September 26, 2008 and extended until further notice on December 22, 2008.

DHA/EPA-rich phosphatidylcholine (PC) was successfully synthesized by immobilized phospholipase A1 (PLA1)-catalyzed transesterification of PC and DHA/EPA-rich ethyl esters in a solvent-free system. Effects of reaction temperature, water addition and substrate mass ratio on the incorporation of DHA/EPA were evaluated using response surface methods (RSM). Water addition had most significant effect on the incorporation. Reaction temperature and substrate mass ratio, however, had no significant effect on the incorporation. The maximal incorporation was 19.09 % (24 h) under the following conditions: temperature 55.7 °C, water addition 1.1 wt % and substrate mass ratio (ethyl esters/PC) 6.8:1. Furthermore, effects of water addition (from 0 to 1.25 wt %) on DHA/EPA incorporation and the composition of products were further investigated. The immobilized PLA1 was more active when water addition was above 0.5 wt %. By monitoring the reaction processes with different water addition, a possible reaction scheme was proposed for transesterification of PC with DHA/EPA-rich ethyl esters. In summary, PC and sn2-lysophosphatidylocholine (LPC) were predominant in the mixtures at early stages of reaction, whereas sn1-LPC and glycerophosphocholine (GPC) predominant at later stages. The vacuum employed after 24 h significantly increased the incorporation of DHA/EPA and the composition of PC, and the highest incorporation (30.31 %) of DHA/EPA was obtained at 72 h and the yield of PC was 47.2 %.

2011-07-14

...EPA is proposing to approve in part and disapprove in part state implementation plan (SIP) revisions submitted by California to provide for attainment of the 1997 fine particulate matter (PM2.5) national ambient air quality standards in the Los Angeles-South Coast area (South Coast). These SIP revisions are the South Coast 2007 Air Quality Management Plan (South Coast 2007 AQMP) (revised 2011) and South Coast-related provisions of the 2007 State Strategy (revised 2009 and 2011). EPA is proposing to approve the emissions inventories; air quality modeling; reasonably available control measures/reasonably available control technology demonstration; the reasonable further progress and attainment demonstrations; and the transportation conformity motor vehicle emissions budgets. EPA is also proposing to grant California's request to extend the attainment deadline for the South Coast to April 5, 2015 and to approve commitments to measures and reductions by the South Coast Air Quality Management District and the California Air Resources Board. Finally, we are proposing to disapprove the SIP's contingency measures and to reject the assignment of 10 tpd of NOX reductions to the federal government. This proposed rule amends EPA's November 22, 2010 proposed rule (75 FR 91294) on the South Coast PM2.5 plan and 2007 State strategy.

Highly Sensitive Determination of 2,4,6-Trinitrotoluene and Related Byproducts Using a Diol Functionalized Column for High Performance Liquid Chromatography

PubMed Central

Gumuscu, Burcu; Erdogan, Zeynep; Guler, Mustafa O.; Tekinay, Turgay

2014-01-01

In this work, a new detection method for complete separation of 2,4,6-trinitrotoluene (TNT); 2,4-dinitrotoluene (2,4-DNT); 2,6-dinitrotoluene (2,6-DNT); 2-aminodinitrotoluene (2-ADNT) and 4-aminodinitrotoluene (4-ADNT) molecules in high-performance liquid-chromatography (HPLC) with UV sensor has been developed using diol column. This approach improves on cost, time, and sensitivity over the existing methods, providing a simple and effective alternative. Total analysis time was less than 13 minutes including column re-equilibration between runs, in which water and acetonitrile were used as gradient elution solvents. Under optimized conditions, the minimum resolution between 2,4-DNT and 2,6-DNT peaks was 2.06. The recovery rates for spiked environmental samples were between 95–98%. The detection limits for diol column ranged from 0.78 to 1.17 µg/L for TNT and its byproducts. While the solvent consumption was 26.4 mL/min for two-phase EPA and 30 mL/min for EPA 8330 methods, it was only 8.8 mL/min for diol column. The resolution was improved up to 49% respect to two-phase EPA and EPA 8330 methods. When compared to C-18 and phenyl-3 columns, solvent usage was reduced up to 64% using diol column and resolution was enhanced approximately two-fold. The sensitivity of diol column was afforded by the hydroxyl groups on polyol layer, joining the formation of charge-transfer complexes with nitroaromatic compounds according to acceptor-donor interactions. Having compliance with current requirements, the proposed method demonstrates sensitive and robust separation. PMID:24905826

2018-07-01

To develop entrustable professional activities (EPAs) for psychiatry and to demonstrate an innovative, validity-enhancing methodology that may be relevant to other specialties. A national task force employed a three-stage process from May 2014 to February 2017 to develop EPAs for psychiatry. In stage 1, the task force used an iterative consensus-driven process to construct proposed EPAs. Each included a title, full description, and relevant competencies. In stage 2, the task force interviewed four nonpsychiatric experts in EPAs and further revised the EPAs. In stage 3, the task force performed a Delphi study of national experts in psychiatric education and assessment. All survey participants completed a brief training program on EPAs. Quantitative and qualitative analysis led to further modifications. Essentialness was measured on a five-point scale. EPAs were included if the content validity index was at least 0.8 and the lower end of the asymmetric confidence interval was not lower than 4.0. Stages 1 and 2 yielded 24 and 14 EPAs, respectively. In stage 3, 31 of the 39 invited experts participated in both rounds of the Delphi study. Round 1 reduced the proposed EPAs to 13. Ten EPAs met the inclusion criteria in Round 2. The final EPAs provide a strong foundation for competency-based assessment in psychiatry. Methodological features such as critique by nonpsychiatry experts, a national Delphi study with frame-of-reference training, and stringent inclusion criteria strengthen the content validity of the findings and may serve as a model for future efforts in other specialties.

...EPA is proposing a limited approval and a limited disapproval of six revisions to the Virginia State Implementation Plan (SIP) submitted by the Commonwealth of Virginia, through the Department of Environmental Quality (VADEQ), that address regional haze for the first implementation period. These revisions address the requirements of the Clean Air Act (CAA or Act) and EPA's rules that require states to prevent any future and remedy any existing anthropogenic impairment of visibility in mandatory Class I areas (national parks and wilderness areas) caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ``regional haze program''). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. EPA is proposing a limited approval of these SIP revisions to implement the regional haze requirements for Virginia on the basis that the revisions, as a whole, strengthen the Virginia SIP. Also in this action, EPA is proposing a limited disapproval of these same SIP revisions because of the deficiencies in the Commonwealth's regional haze SIP submittal arising from the remand by the U.S. Court of Appeals for the District of Columbia (DC Circuit) to EPA of the Clean Air Interstate Rule (CAIR). EPA is also proposing to approve this revision as meeting the infrastructure requirements relating to visibility protection for the 1997 8-Hour Ozone National Ambient Air Quality Standard (NAAQS) and the 1997 and 2006 fine particulate matter (PM2.5) NAAQS.

The Environmental Protection Agency has released the White House-instituted hold and review on the Bush Administration's last-minute rules and proposals. Of the 32 actions, EPA administrator Carol Browner has held back only one, which proposed a fee system for discharges to water. Any changes in the future were deemed to best be considered either in the comment period for proposals or with new proposed addendums for final rules, said Browner. Although a proposal concerning standards for reformulated gasoline was approved for publication, Browner emphasizes that the EPA can modify or drop provisions for ethanol mixtures and remains committed to negotiatedmore » rulemaking procedures. The proposed rule includes measures - set out by Bush last October - to grant ethanol a waiver from gasoline vapor pressure limits, resulting in a 30% market share for northern cities in violation of ozone limits. Ethanol could take a 20% share in southern cities. Under the ethanol waiver, refiners would have to offset the increased emissions from ethanol at a cost of at least $250 million, according to the American Petroleum Institute, API, state air pollution regulators, and environmentalists say the proposal violates a regulatory negotiation. Regarding the one-week delay, API says, The lengthy rule-making process already has drastically reduced the lead time available to refiners, who must begin selling this fuel on January 1, 1995'. Also released is the ozone-depleter phase-out proposal. In addition to chlorofluorocarbons, the Bush EPA slated methyl bromide for phase-outby the year 2000.« less

Models of performance of evolutionary program induction algorithms based on indicators of problem difficulty.

PubMed

Graff, Mario; Poli, Riccardo; Flores, Juan J

2013-01-01

Modeling the behavior of algorithms is the realm of evolutionary algorithm theory. From a practitioner's point of view, theory must provide some guidelines regarding which algorithm/parameters to use in order to solve a particular problem. Unfortunately, most theoretical models of evolutionary algorithms are difficult to apply to realistic situations. However, in recent work (Graff and Poli, 2008, 2010), where we developed a method to practically estimate the performance of evolutionary program-induction algorithms (EPAs), we started addressing this issue. The method was quite general; however, it suffered from some limitations: it required the identification of a set of reference problems, it required hand picking a distance measure in each particular domain, and the resulting models were opaque, typically being linear combinations of 100 features or more. In this paper, we propose a significant improvement of this technique that overcomes the three limitations of our previous method. We achieve this through the use of a novel set of features for assessing problem difficulty for EPAs which are very general, essentially based on the notion of finite difference. To show the capabilities or our technique and to compare it with our previous performance models, we create models for the same two important classes of problems-symbolic regression on rational functions and Boolean function induction-used in our previous work. We model a variety of EPAs. The comparison showed that for the majority of the algorithms and problem classes, the new method produced much simpler and more accurate models than before. To further illustrate the practicality of the technique and its generality (beyond EPAs), we have also used it to predict the performance of both autoregressive models and EPAs on the problem of wind speed forecasting, obtaining simpler and more accurate models that outperform in all cases our previous performance models.

Setting a protective PM standard: A view from the frontline

DOE Office of Scientific and Technical Information (OSTI.GOV)

John Paul; Eddie Terrill

2006-06-15

Several aspects of the US EPA's recent proposal to revise the particulate matter (PM) standards deeply concern state and local air agencies and their representatives with the State and Territorial Air Pollution Program Administrators and the Association of Local Air Pollution Control Offices (STAPPA and ALAPCO). STAPPA and ALAPCO urge EPA to follow the recommendations of its appointed scientific experts and lower the annual average standard to 13 or 14 {mu}mg/m{sup 3} in addition to lowering the daily standard to 35 {mu}m/m{sup 3}. Unless EPA strengthens its proposal consistent with the recommendations of the Clean Air Scientific Advisory Committee (CASAC),more » STAPPA and ALAPCO are extremely concerned that we will continue to see significant increased premature mortality and adverse health effects throughout the country. For the reasons described in the article STAPPA and ALAPCO urge EPA to eliminate the exemptions for agriculture, mining and rural windblown dust. STAPPA and ALAPCO are troubled that EPA has ignored any commitment to funding the proposed coarse PM network scheduled for deployment in Fiscal Year (FY) 2008. EPA has estimated that the capital costs of this monitoring network could easily exceed US$ 14 million, with annual operating expenses of approximately US$ 13 million. State and local agencies will simply not be able to assume these significant costs. 33 refs.« less

Evaluation of a staged fuel combustor for turboprop engines

NASA Technical Reports Server (NTRS)

Verdouw, A. J.

1976-01-01

Proposed EPA emission regulations require emission reduction by 1979 for various gas turbine engine classes. Extensive combustion technology advancements are required to meet the proposed regulations. The T56 turboprop engine requires CO, UHC, and smoke reduction. A staged fuel combustor design was tested on a combustion rig to evaluate emission reduction potential in turboprop engines from fuel zoning. The can-type combustor has separately fueled-pilot and main combustion zones in series. The main zone fueling system was arranged for potential incorporation into the T56 with minor or no modifications to the basic engine. Three combustor variable geometry systems were incorporated to evaluate various airflow distributions. Emission results with fixed geometry operation met all proposed EPA regulations over the EPA LTO cycle. CO reduction was 82 percent, UHC reduction was 96 percent, and smoke reduction was 84 percent. NOx increased 14 percent over the LTO cycle. At high power, NOx reduction was 40 to 55 percent. This NOx reduction has potential application to stationary gas turbine powerplants which have different EPA regulations.

...EPA is proposing a limited approval and limited disapproval of a State Implementation Plan (``SIP'') revision submitted by the State of California on November 17, 2007, for the purpose of addressing the ``transport SIP'' provisions of Clean Air Act (``CAA'') section 110(a)(2)(D)(i) for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS or standards) and the 1997 fine particulate matter (``PM2.5'') NAAQS. Section 110(a)(2)(D)(i) of the CAA requires that each SIP contain adequate provisions to prohibit emissions that adversely affect air quality in other States through interstate transport. EPA is proposing a limited approval and limited disapproval of California's SIP revision for the 1997 8-hour ozone and 1997 PM2.5 NAAQS with respect to the requirement in CAA section 110(a)(2)(D)(i)(II) that each SIP contain adequate measures prohibiting emissions of air pollutants in amounts which will interfere with other States' measures required under title I, part C of the CAA to prevent significant deterioration of air quality. Specifically, EPA is proposing to approve California's SIP revision with respect to those Districts in California that implement SIP-approved permit programs meeting the approval criteria under CAA section 110(a)(2)(D)(i), as discussed in this proposal. EPA is simultaneously proposing to disapprove California's SIP revision with respect to those Districts in California that do not implement SIP-approved permit programs meeting these approval criteria. For any District for which we finalize a disapproval, EPA intends to simultaneously promulgate a limited Federal Implementation Plan (``FIP''), as discussed in this proposal, unless the relevant area is already subject to a FIP.

2013-06-14

...In this Notice of Proposed Rulemaking, EPA is proposing amendments to three separate sets of regulations relating to fuels. First, EPA is proposing to amend certain of the renewable fuels standard (RFS2) program regulations. We believe these proposals will facilitate the introduction of new renewable fuels as well as improve implementation of the program. This proposal includes various changes related to biogas, including changes related to the revised compressed natural gas (CNG)/liquefied natural gas (LNG) pathway and amendments to various associated registration, recordkeeping, and reporting provisions. This proposed regulation includes the addition of new pathways for renewable diesel, renewable naphtha, and renewable electricity (used in electric vehicles) produced from landfill biogas. Adding these new pathways will enhance the ability of the biofuels industry to supply advanced biofuels, including cellulosic biofuels, which greatly reduce the greenhouse gas emissions (GHG) compared to the petroleum-based fuels they replace. It also addresses ``nameplate capacity'' issues for certain production facilities that do not claim exemption from the 20% greenhouse gas (GHG) reduction threshold. In this notice, EPA addresses issues related to crop residue and corn kernel fiber and proposes an approach to determining the volume of cellulosic RINs produced from various cellulosic feedstocks. We also include a lifecycle analysis of advanced butanol and discuss the potential to allow for commingling of compliant products at the retail facility level as long as the environmental performance of the fuels would not be detrimental. Several other amendments to the RFS2 program are included. Second, EPA is also proposing various changes to the E15 misfueling mitigation regulations (E15 MMR). Among the E15 changes proposed are technical corrections and amendments to sections dealing with labeling, E15 surveys, product transfer documents, and prohibited acts. We also propose to amend the definitions in order to address a concern about the rounding of test results for ethanol content violations. Lastly, EPA is proposing changes to the survey requirements associated with the ultra-low sulfur diesel (ULSD) program.

...The EPA is proposing to amend the new source performance standards (NSPS) for stationary gas turbines and stationary combustion turbines. These amendments are primarily in response to issues raised by the regulated community. On July 6, 2006, the EPA promulgated amendments to the new source performance standards for stationary combustion turbines. On September 5, 2006, the Utility Air Regulatory Group filed a petition for reconsideration of certain aspects of the promulgated standards. The EPA is proposing to amend specific provisions in the NSPS to resolve issues and questions raised by the petition for reconsideration, and to address other technical and editorial issues. In addition, this proposed rule would amend the location and wording of existing paragraphs for clarity. The proposed amendments would increase the environmental benefits of the existing requirements because the emission standards would apply at all times. The proposed amendments would also promote efficiency by recognizing the environmental benefit of combined heat and power and the beneficial use of low energy content gases.

Analysis of Carbamate Pesticides: Validation of Semi-Volatile Analysis by HPLC-MS/MS by EPA Method MS666

DOE Office of Scientific and Technical Information (OSTI.GOV)

Owens, J; Koester, C

The Environmental Protection Agency's (EPA) Region 5 Chicago Regional Laboratory (CRL) developed a method for analysis of aldicarb, bromadiolone, carbofuran, oxamyl, and methomyl in water by high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS), titled Method EPA MS666. This draft standard operating procedure (SOP) was distributed to multiple EPA laboratories and to Lawrence Livermore National Laboratory, which was tasked to serve as a reference laboratory for EPA's Environmental Reference Laboratory Network (ERLN) and to develop and validate analytical procedures. The primary objective of this study was to validate and verify the analytical procedures described in MS666 for analysis of carbamatemore » pesticides in aqueous samples. The gathered data from this validation study will be used to: (1) demonstrate analytical method performance; (2) generate quality control acceptance criteria; and (3) revise the SOP to provide a validated method that would be available for use during a homeland security event. The data contained in this report will be compiled, by EPA CRL, with data generated by other EPA Regional laboratories so that performance metrics of Method EPA MS666 can be determined.« less

...EPA is proposing a limited approval and a limited disapproval of a revision to the West Virginia State Implementation Plan (SIP) submitted by the State of West Virginia through the West Virginia Department of Environmental Protection (WVDEP) on June 18, 2008, that addresses regional haze for the first implementation period. This revision addresses the requirements of the Clean Air Act (CAA) and EPA's rules that require states to prevent any future, and remedy any existing, anthropogenic impairment of visibility in mandatory Class I areas caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ``regional haze program''). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. EPA is proposing a limited approval of this SIP revision to implement the regional haze requirements for West Virginia on the basis that the revision, as a whole, strengthens the West Virginia SIP. Also in this action, EPA is proposing a limited disapproval of this same SIP revision because of the deficiencies in the State's June 2008 regional haze SIP submittal arising from the remand by the U.S. Court of Appeals for the District of Columbia (D.C. Circuit) to EPA of the Clean Air Interstate Rule (CAIR). EPA is also proposing to approve this revision as meeting the requirements of 110(a)(2)(D)(i)(II) and 110(a)(2)(J), relating to visibility protection for the 1997 8-Hour Ozone National Ambient Air Quality Standard (NAAQS) and the 1997 and 2006 fine particulate matter (PM2.5) NAAQS.

Characterization of background concentrations of contaminants using a mixture of normal distributions.

PubMed

Qian, Song S; Lyons, Regan E

2006-10-01

We present a Bayesian approach for characterizing background contaminant concentration distributions using data from sites that may have been contaminated. Our method, focused on estimation, resolves several technical problems of the existing methods sanctioned by the U.S. Environmental Protection Agency (USEPA) (a hypothesis testing based method), resulting in a simple and quick procedure for estimating background contaminant concentrations. The proposed Bayesian method is applied to two data sets from a federal facility regulated under the Resource Conservation and Restoration Act. The results are compared to background distributions identified using existing methods recommended by the USEPA. The two data sets represent low and moderate levels of censorship in the data. Although an unbiased estimator is elusive, we show that the proposed Bayesian estimation method will have a smaller bias than the EPA recommended method.

...The EPA published in the Federal Register on November 25, 2011, the proposed rules, ``National Emission Standards for Hazardous Air Pollutants: Mineral Wool Production and Wool Fiberglass Manufacturing.'' The EPA was asked to hold a public hearing only on the wool fiberglass manufacturing proposed rule, and on December 20, 2011, published a notice announcing the hearing and extending the comment period for only the wool fiberglass manufacturing proposed rule (76 FR 78872). The comment period for the mineral wool production proposed rule was not extended because no public hearing was requested and no requests for an extension of the comment period were received. It has come to our attention that confusion arose from the result of having two different comment periods for the two proposed rules in the same action. Therefore, the EPA is extending the public comment period for the mineral wool production proposed rule for 10 days from January 24, 2012 to February 3, 2012, so that comments on both rules in this action are due on the same date.

Introduction to benchmark dose methods and U.S. EPA's benchmark dose software (BMDS) version 2.1.1

DOE Office of Scientific and Technical Information (OSTI.GOV)

Davis, J. Allen, E-mail: davis.allen@epa.gov; Gift, Jeffrey S.; Zhao, Q. Jay

Traditionally, the No-Observed-Adverse-Effect-Level (NOAEL) approach has been used to determine the point of departure (POD) from animal toxicology data for use in human health risk assessments. However, this approach is subject to substantial limitations that have been well defined, such as strict dependence on the dose selection, dose spacing, and sample size of the study from which the critical effect has been identified. Also, the NOAEL approach fails to take into consideration the shape of the dose-response curve and other related information. The benchmark dose (BMD) method, originally proposed as an alternative to the NOAEL methodology in the 1980s, addressesmore » many of the limitations of the NOAEL method. It is less dependent on dose selection and spacing, and it takes into account the shape of the dose-response curve. In addition, the estimation of a BMD 95% lower bound confidence limit (BMDL) results in a POD that appropriately accounts for study quality (i.e., sample size). With the recent advent of user-friendly BMD software programs, including the U.S. Environmental Protection Agency's (U.S. EPA) Benchmark Dose Software (BMDS), BMD has become the method of choice for many health organizations world-wide. This paper discusses the BMD methods and corresponding software (i.e., BMDS version 2.1.1) that have been developed by the U.S. EPA, and includes a comparison with recently released European Food Safety Authority (EFSA) BMD guidance.« less

Data disclosure for chemical evaluations.

PubMed

Lutter, Randall; Barrow, Craig; Borgert, Christopher J; Conrad, James W; Edwards, Debra; Felsot, Allan

2013-02-01

Public disclosure of scientific data used by the government to make regulatory decisions for chemicals is a practical step that can enhance public confidence in the scientific basis of such decisions. We reviewed the U.S. Environmental Protection Agency's (EPA) current practices regarding disclosure of data underlying regulatory and policy decisions involving chemicals, including pesticides. We sought to identify additional opportunities for the U.S. EPA to disclose data and, more generally, to promote broad access to data it uses, regardless of origin. We recommend that when the U.S. EPA proposes a regulatory determination or other policy decision that relies on scientific research, it should provide sufficient underlying raw data and information about methods to enable reanalysis and attempts to independently reproduce the work, including the sensitivity of results to alternative analyses. This recommendation applies regardless of who conducted the work. If the U.S. EPA is unable to provide such transparency, it should state whether it had full access to all underlying data and methods. A timely version of submitted data cleared of information about confidential business matters and personal privacy should fully meet the standards of transparency described below, including public access sufficient for others to undertake an independent reanalysis. Reliable chemical evaluation is essential for protecting public health and the environment and for ensuring availability of useful chemicals under appropriate conditions. Permitting qualified researchers to endeavor to independently reproduce the analyses used in regulatory determinations of pesticides and other chemicals would increase confidence in the scientific basis of such determinations.

Final programmatic environmental impact statement for the uranium mill tailings remedial action ground water project. Volume I

DOE Office of Scientific and Technical Information (OSTI.GOV)

None

1996-10-01

This programmatic environmental impact statement (PElS) was prepared for the Uranium Mill Tailings Remedial Action (UMTRA) Ground Water Project to comply with the National Environmental Policy Act (NEPA). This PElS provides an analysis of the potential impacts of the alternatives and ground water compliance strategies as well as potential cumulative impacts. On November 8, 1978, Congress enacted the Uranium Mill Tailings Radiation Control Act (UMTRCA) of 1978, Public Law, codified at 42 USC §7901 et seq. Congress found that uranium mill tailings " ... may pose a potential and significant radiation health hazard to the public, and that every reasonablemore » effort should be made to provide for stabilization, disposal, and control in a safe, and environmentally sound manner of such tailings in order to prevent or minimize other environmental hazards from such tailings." Congress authorized the Secretary of Energy to designate inactive uranium processing sites for remedial action by the U.S. Department of Energy (DOE). Congress also directed the U.S. Environmental Protection Agency (EPA) to set the standards to be followed by the DOE for this process of stabilization, disposal, and control. On January 5, 1983, EPA published standards (40 CFR Part 192) for the disposal and cleanup of residual radioactive materials. On September 3, 1985, the U.S. Court of Appeals for the Tenth Circuit set aside and remanded to EPA the ground water provisions of the standards. The EPA proposed new standards to replace remanded sections and changed other sections of 40 CFR Part 192. These proposed standards were published in the Federal Register on September 24, 1987 (52 FR 36000). Section 108 of the UMTRCA requires that DOE comply with EPA's proposed standards in the absence of final standards. The Ground Water Project was planned under the proposed standards. On January 11, 1995, EPA published the final rule, with which the DOE must now comply. The PElS and the Ground Water Project are in accordance with the final standards. The EPA reserves the right to modify the ground water standards, if necessary, based on changes in EPA drinking water standards. Appendix A contains a copy of the 1983 EPA ground water compliance standards, the 1987 proposed changes to the standards, and the 1995 final rule. Under UMTRA, DOE is responsible for bringing the designated processing sites into compliance with the EPA ground water standards and complying with all other applicable standards and requirements. The U.S. Nuclear Regulatory Commission (NRC) must concur with DOE's actions. States are full participants in the process. The DOE also must consult with any affected Indian tribes and the Bureau of Indian Affairs. Uranium processing activities at most of the inactive mill sites resulted in the contamination of ground water beneath and, in some cases, downgradient of the sites. This contaminated ground water often has elevated levels of constituents such as but not limited to uranium and nitrates. The purpose of the UMTRA Ground Water Project is to eliminate or reduce to acceptable levels the potential health and environmental consequences of milling activities by meeting the EPA ground water standards.« less

A component modes projection and assembly model reduction methodology for articulated, multi-flexible body structures

NASA Technical Reports Server (NTRS)

Lee, Allan Y.; Tsuha, Walter S.

1993-01-01

A two-stage model reduction methodology, combining the classical Component Mode Synthesis (CMS) method and the newly developed Enhanced Projection and Assembly (EP&A) method, is proposed in this research. The first stage of this methodology, called the COmponent Modes Projection and Assembly model REduction (COMPARE) method, involves the generation of CMS mode sets, such as the MacNeal-Rubin mode sets. These mode sets are then used to reduce the order of each component model in the Rayleigh-Ritz sense. The resultant component models are then combined to generate reduced-order system models at various system configurations. A composite mode set which retains important system modes at all system configurations is then selected from these reduced-order system models. In the second stage, the EP&A model reduction method is employed to reduce further the order of the system model generated in the first stage. The effectiveness of the COMPARE methodology has been successfully demonstrated on a high-order, finite-element model of the cruise-configured Galileo spacecraft.

...EPA is proposing to partially approve and partially disapprove a Washington Regional Haze Implementation Plan (SIP) submitted by the State of Washington on December 22, 2010, that addresses regional haze for the first implementation period. This plan was submitted to meet the requirements of Clean Air Act (CAA) sections 169A and 169B that require states to prevent any future and remedy any existing man-made impairment of visibility in mandatory Class I areas. EPA is proposing to: (1) Approve portions of this SIP submittal as meeting most of the requirements of the regional haze program, (2) propose a limited approval and limited disapproval of the SO2 Best Available Retrofit Technology (BART) determination for Intalco Aluminum Corp. (Intalco) potline operation and propose a federal ``Better than BART'' alternative, and (3) propose to disapprove the NOx BART determination for five BART emission units at the Tesoro Refining and Marketing refinery (Tesoro) and propose a federal Better than BART alternative.

...EPA is proposing a limited approval and a limited disapproval of two revisions to the Kentucky State Implementation Plan (SIP) submitted by the Commonwealth of Kentucky through the Kentucky Energy and Environment Cabinet, Division of Air Quality (KYDAQ), on June 25, 2008, and May 28, 2010, that address regional haze for the first implementation period. These revisions address the requirements of the Clean Air Act (CAA or Act) and EPA's rules that require states to prevent any future and remedy any existing anthropogenic impairment of visibility in mandatory Class I areas (national parks and wilderness areas) caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ``regional haze program''). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. EPA is proposing a limited approval of these SIP revisions to implement the regional haze requirements for Kentucky on the basis that the revisions, as a whole, strengthen the Kentucky SIP. Also in this action, EPA is proposing a limited disapproval of these same SIP revisions because of the deficiencies in the Commonwealth's regional haze SIP submittal arising from the remand by the U.S. Court of Appeals for the District of Columbia Circuit (DC Circuit) to EPA of the Clean Air Interstate Rule (CAIR).

Radon-contaminated drinking water from private wells: an environmental health assessment examining a rural Colorado mountain community's exposure.

PubMed

Cappello, Michael Anthony; Ferraro, Aimee; Mendelsohn, Aaron B; Prehn, Angela Witt

2013-11-01

In the study discussed in this article, 27 private drinking water wells located in a rural Colorado mountain community were sampled for radon contamination and compared against (a) the U.S. Environmental Protection Agency's (U.S. EPA's) proposed maximum contaminant level (MCL), (b) the U.S. EPA proposed alternate maximum contaminate level (AMCL), and (c) the average radon level measured in the local municipal drinking water system. The data from the authors' study found that 100% of the wells within the study population had radon levels in excess of the U.S. EPA MCL, 37% were in excess of the U.S. EPA AMCL, and 100% of wells had radon levels greater than that found in the local municipal drinking water system. Radon contamination in one well was found to be 715 times greater than the U.S. EPA MCL, 54 times greater than the U.S. EPA AMLC, and 36,983 times greater than that found in the local municipal drinking water system. According to the research data and the reviewed literature, the results indicate that this population has a unique and elevated contamination profile and suggest that radon-contaminated drinking water from private wells can present a significant public health concern.

75 FR 31843 - Identification of Non-Hazardous Secondary Materials That Are Solid Waste

Federal Register 2010, 2011, 2012, 2013, 2014

2010-06-04

...On January 2, 2009, the Environmental Protection Agency (EPA or the Agency) issued an Advanced Notice of Proposed Rulemaking (ANPRM) to solicit comment on which non-hazardous secondary materials that are used as fuels or ingredients in combustion units are solid wastes under the Resource Conservation and Recovery Act (RCRA). The meaning of ``solid waste'' as defined under RCRA is of particular importance since it will determine whether a combustion unit is required to meet emissions standards for solid waste incineration units issued under section 129 of the Clean Air Act (CAA) or emissions standards for commercial, industrial, and institutional boilers issued under CAA section 112. CAA section 129 states that the term ``solid waste'' shall have the meaning ``established by the Administrator pursuant to [RCRA].'' EPA is proposing a definition of non-hazardous solid waste that would be used to identify whether non-hazardous secondary materials burned as fuels or used as ingredients in combustion units are solid waste. EPA is also proposing that non-hazardous secondary materials that have been discarded, and are therefore solid wastes, may be rendered products after they have been processed (altered chemically or physically) into a fuel or ingredient product. This proposed rule is necessary to identify units for the purpose of developing certain standards under sections 112 and 129 of the CAA. In addition to this proposed rule, EPA is concurrently proposing air emission requirements under CAA section 112 for industrial, commercial, and institutional boilers and process heaters, as well as air emission requirements under CAA section 129 for commercial and industrial solid waste incineration units.

2011-12-01

...EPA and NHTSA, on behalf of the Department of Transportation, are issuing this joint proposal to further reduce greenhouse gas emissions and improve fuel economy for light-duty vehicles for model years 2017-2025. This proposal extends the National Program beyond the greenhouse gas and corporate average fuel economy standards set for model years 2012-2016. On May 21, 2010, President Obama issued a Presidential Memorandum requesting that NHTSA and EPA develop through notice and comment rulemaking a coordinated National Program to reduce greenhouse gas emissions of light-duty vehicles for model years 2017- 2025. This proposal, consistent with the President's request, responds to the country's critical need to address global climate change and to reduce oil consumption. NHTSA is proposing Corporate Average Fuel Economy standards under the Energy Policy and Conservation Act, as amended by the Energy Independence and Security Act, and EPA is proposing greenhouse gas emissions standards under the Clean Air Act. These standards apply to passenger cars, light-duty trucks, and medium- duty passenger vehicles, and represent a continued harmonized and consistent National Program. Under the National Program for model years 2017-2025, automobile manufacturers would be able to continue building a single light-duty national fleet that satisfies all requirements under both programs while ensuring that consumers still have a full range of vehicle choices. EPA is also proposing a minor change to the regulations applicable to MY 2012-2016, with respect to air conditioner performance and measurement of nitrous oxides.

Pérez-López, Paula; González-García, Sara; Allewaert, Céline; Verween, Annick; Murray, Patrick; Feijoo, Gumersindo; Moreira, Ma Teresa

2014-01-01

Polyunsaturated fatty acids (PUFAs) play an important role in human health. Due to the increased market demand, the production of PUFAs from potential alternative sources such as microalgae is receiving increased interest. The aim of this study was to perform a life cycle assessment (LCA) of the biotechnological production of eicosapentaenoic acid (EPA) from the marine diatom Phaeodactylum tricornutum, followed by the identification of avenues to improve its environmental profile. The LCA tackles two production schemes of P. tricornutum PUFAs with an EPA content of 36%: lab and pilot scales. The results at lab scale show that both the electricity requirements and the production of the extraction agent (chloroform) have significant influence on the life cycle environmental performance of microalgal EPA production. An alternative method based on hexane was proposed to replace chloroform and environmental benefits were identified. Regarding the production of EPA at pilot scale, three main environmental factors were identified: the production of the nitrogen source required for microalgae growing, the transport activities and electricity requirements. Improvement alternatives were proposed and discussed concerning: a) the use of nitrogen based fertilizers, b) the valorization of the residual algal paste as soil conditioner and, c) the anaerobic digestion of the residual algal paste for bioenergy production. Encouraging environmental benefits could be achieved if sodium nitrate was substituted by urea, calcium nitrate or ammonium nitrate, regardless the category under assessment. In contrast, minor improvement was found when valorizing the residual algal paste as mineral fertilizer, due to its overall low content in N and P. Concerning the biogas production from the anaerobic digestion, the improvement on the environmental profile was also limited due to the discrepancy between the potential energy production from the algal paste and the high electricity requirements in the culturing and extraction stages. © 2013.

Feasibility of the determination of polycyclic aromatic hydrocarbons in edible oils via unfolded partial least-squares/residual bilinearization and parallel factor analysis of fluorescence excitation emission matrices.

PubMed

Alarcón, Francis; Báez, María E; Bravo, Manuel; Richter, Pablo; Escandar, Graciela M; Olivieri, Alejandro C; Fuentes, Edwar

2013-01-15

The possibility of simultaneously determining seven concerned heavy polycyclic aromatic hydrocarbons (PAHs) of the US-EPA priority pollutant list, in extra virgin olive and sunflower oils was examined using unfolded partial least-squares with residual bilinearization (U-PLS/RBL) and parallel factor analysis (PARAFAC). Both of these methods were applied to fluorescence excitation emission matrices. The compounds studied were benzo[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenz[a,h]anthracene, benzo[g,h,i]perylene and indeno[1,2,3-c,d]-pyrene. The analysis was performed using fluorescence spectroscopy after a microwave assisted liquid-liquid extraction and solid-phase extraction on silica. The U-PLS/RBL algorithm exhibited the best performance for resolving the heavy PAH mixture in the presence of both the highly complex oil matrix and other unpredicted PAHs of the US-EPA list. The obtained limit of detection for the proposed method ranged from 0.07 to 2 μg kg(-1). The predicted U-PLS/RBL concentrations were satisfactorily compared with those obtained using high-performance liquid chromatography with fluorescence detection. A simple analysis with a considerable reduction in time and solvent consumption in comparison with chromatography are the principal advantages of the proposed method. Copyright © 2012 Elsevier B.V.

Optimization of one-step in situ transesterification method for accurate quantification of EPA in Nannochloropsis gaditana

DOE PAGES

Tang, Yuting; Zhang, Yue; Rosenberg, Julian N.; ...

2016-11-08

Microalgae are a valuable source of lipid feedstocks for biodiesel and valuable omega-3 fatty acids. Nannochloropsis gaditana has emerged as a promising producer of eicosapentaenoic acid (EPA) due to its fast growth rate and high EPA content. In the present study, the fatty acid profile of Nannochloropsis gaditana was found to be naturally high in EPA and devoid of docosahexaenoic acid (DHA), thereby providing an opportunity to maximize the efficacy of EPA production. Using an optimized one-step in situ transesterification method (methanol:biomass = 90 mL/g; HCl 5% by vol.; 70 °C; 1.5 h), the maximum fatty acid methyl ester (FAME)more » yield of Nannochloropsis gaditana cultivated under rich condition was quantified as 10.04% ± 0.08% by weight with EPA-yields as high as 4.02% ± 0.17% based on dry biomass. The total FAME and EPA yields were 1.58- and 1.23-fold higher separately than that obtained using conventional two-step method (solvent system: methanol and chloroform). Furthermore, this one-step in situ method provides a fast and simple method to measure fatty acid methyl ester (FAME) yields and could serve as a promising method to generate eicosapentaenoic acid methyl ester from microalgae.« less

Evaluation of the WIPP Project`s compliance with the EPA radiation protection standards for disposal of transuranic waste

DOE Office of Scientific and Technical Information (OSTI.GOV)

Neill, R.H.; Chaturvedi, L.; Rucker, D.F.

The US Environmental Protection Agency`s (EPA) proposed rule to certify that the Waste Isolation Pilot Plant (WIPP) meets compliance with the long-term radiation protection standards for geologic repositories (40CFR191 Subparts B and C), is one of the most significant milestones to date for the WIPP project in particular, and for the nuclear waste issue in general. The Environmental Evaluation Group (EEG) has provided an independent technical oversight for the WIPP project since 1978, and is responsible for many improvements in the location, design, and testing of various aspects of the project, including participation in the development of the EPA standardsmore » since the early 1980s. The EEG reviewed the development of documentation for assessing the WIPP`s compliance by the Sandia National Laboratories following the 1985 promulgation by EPA, and provided many written and verbal comments on various aspects of this effort, culminating in the overall review of the 1992 performance assessment. For the US Department of Energy`s (DOE) compliance certification application (CCA), the EEG provided detailed comments on the draft CCA in March, 1996, and additional comments through unpublished letters in 1997 (included as Appendices 8.1 and 8.2 in this report). Since the October 30, 1997, publication of the EPA`s proposed rule to certify WIPP, the EEG gave presentations on important issues to the EPA on December 10, 1997, and sent a December 31, 1997 letter with attachments to clarify those issues (Appendix 8.3). The EEG has raised a number of questions that may have an impact on compliance. In spite of the best efforts by the EEG, the EPA reaction to reviews and suggestions has been slow and apparently driven by legal considerations. This report discusses in detail the questions that have been raised about containment requirements. Also discussed are assurance requirements, groundwater protection, individual protection, and an evaluation of EPA`s responses to EEG`s comments.« less

Data Disclosure for Chemical Evaluations

PubMed Central

Barrow, Craig; Borgert, Christopher J.; Conrad, James W.; Edwards, Debra; Felsot, Allan

2012-01-01

Background: Public disclosure of scientific data used by the government to make regulatory decisions for chemicals is a practical step that can enhance public confidence in the scientific basis of such decisions. Objectives: We reviewed the U.S. Environmental Protection Agency’s (EPA) current practices regarding disclosure of data underlying regulatory and policy decisions involving chemicals, including pesticides. We sought to identify additional opportunities for the U.S. EPA to disclose data and, more generally, to promote broad access to data it uses, regardless of origin. Discussion: We recommend that when the U.S. EPA proposes a regulatory determination or other policy decision that relies on scientific research, it should provide sufficient underlying raw data and information about methods to enable reanalysis and attempts to independently reproduce the work, including the sensitivity of results to alternative analyses. This recommendation applies regardless of who conducted the work. If the U.S. EPA is unable to provide such transparency, it should state whether it had full access to all underlying data and methods. A timely version of submitted data cleared of information about confidential business matters and personal privacy should fully meet the standards of transparency described below, including public access sufficient for others to undertake an independent reanalysis. Conclusion: Reliable chemical evaluation is essential for protecting public health and the environment and for ensuring availability of useful chemicals under appropriate conditions. Permitting qualified researchers to endeavor to independently reproduce the analyses used in regulatory determinations of pesticides and other chemicals would increase confidence in the scientific basis of such determinations.

Fish oil is a popular nutritional product consumed in Hong Kong. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are the two main bioactive components responsible for the health benefits of fish oil. Market survey in Hong Kong demonstrated that various fish oil capsules with different origins and prices are sold simultaneously. However, these capsules are labelled with same ingredient levels, namely EPA 180 mg/g and DHA 120 mg/g. This situation makes the consumers very confused. To evaluate the quality of various fish oil capsules, a comparative analysis of the contents of EPA and DHA in fish oil is crucial. A gas chromatography-mass spectrometry (GC-MS) method was developed for identification and determination of EPA and DHA in fish oil capsules. A comprehensive validation of the developed method was conducted. Ten batches of fish oil capsules samples purchased from drugstores of Hong Kong were analyzed by using the developed method. The present method presented good sensitivity, precision and accuracy. The limits of detection (LOD) for EPA and DHA were 0.08 ng and 0.21 ng, respectively. The relative standard deviation (RSD) values of EPA and DHA for repeatability tests were both less than 1.05%; and the recovery for accuracy test of EPA and DHA were 100.50% and 103.83%, respectively. In ten fish oil samples, the contents of EPA ranged from 39.52 mg/g to 509.16 mg/g, and the contents of DHA ranged from 35.14 mg/g to 645.70 mg/g. The present method is suitable for the quantitative analysis of EPA and DHA in fish oil capsules. There is a significant variation in the contents of the quantified components in fish oil samples, and there is not a linear relationship between price and contents of EPA and DHA. Strict supervision of the labelling of the fish oil capsules is urgently needed.

This revision addresses the requirements of the Clean Air Act (CAA or ``Act'') and EPA's rules that require states to prevent any future and remedy any existing anthropogenic impairment of visibility in mandatory Class I areas caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ``regional haze program''). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. EPA is proposing a limited approval of this SIP revision to implement the regional haze requirements for Missouri on the basis that the revision, as a whole, strengthens the Missouri SIP. In a separate action EPA has previously proposed a limited disapproval of the Missouri regional haze SIP because of deficiencies in the State's regional haze SIP submittal arising from the remand by the U.S. Court of Appeals for the District Court of Columbia (DC Circuit) to the EPA of the Clean Air Interstate Rule (CAIR). See 76 FR 82219. Therefore, we are not taking action in this notice to address the State's reliance on CAIR to meet certain regional haze requirements.

Exxon Company U.S.A. may be the first company ever exempted from federal restrictions that prohibit companies from disposing of untreated hazardous waste on land. EPA recently proposed to grant a [open quotes]no-migration variance[close quotes] to Exxon at the New South Land Treatment Unit of the company's Billings, Mont., refinery. Exxon seeks to continue disposing of hazardous wastes, including solids, emulsions, and wastes that contain benzene, from its refinery operations on land. Citizens and environmental groups are concerned about land farming, the method by which Exxon proposes to dispose of the waste. Land farming involves tilling waste into the upper 300more » mm (12 in.) of soil. Microbes in the soil break down the organic wastes, while inorganic wastes such as heavy metals are immobilized by way of adsorption. Exxon has installed berms and dikes around the farm to prevent runoff from reaching surface water. EPA and its state counterpart say that Exxon has shown, to a reasonable degree of certainty, that the hazardous constituents will not migrate. Groundwater analysis so far has shown no migration.« less

Antinuclear antibody (ANA) testing is indispensable for diagnosing and understanding clinical conditions of autoimmune diseases. The indirect immunofluorescence assay (IFA) is the gold standard for ANA screening, and it can detect more than 100 different antibodies, such as anti-PCNA as well as anti-cytoplasmic antibodies. However, complicated procedures of conventional IFA and visual interpretation require highly skilled laboratory staff. This study evaluates the capability, characteristics, and applicability of the recently developed ANA detection system (EUROPattern Cosmic IFA System, EPA) using HEp20-10 cells and the automated pattern recognition microscope. Findings using EPA and conventional methods were compared in 282 sera obtained from connective tissue disease patients and 250 sera from healthy individuals. The concordance of the positivity rate, antibody titer (within +/- 1 tube difference), and the accurate recognition rate of ANA patterns between the automated EPA method and the microscopic judgement of the EPA image by eye was 98.9, 97.4, and 55.3%, respectively. The EPA method showed concordance of the positivity rate as high as 93.3% and concordance of the antibody titer as high as 94.0% (within +/- 1 titer) compared with the conventional method. Regarding the four typical patterns of ANA (homogeneous, speckled, nucleolar, and centromere), large differences between the EPA and conventional methods were not observed, and the rate of concordance between the final EPA result and the conventional method was from 94.1 to 100%. The positivity rate of ANA using the EPA and conventional methods showed marked agreement among the six connective tissue diseases (SLE, MCTD, SSc, PM/DM, and SS) and healthy individuals. Although the EPA system is not considered a complete system and laboratory staff should verify the results, it is a useful system for routine ANA analysis because it contributes to ANA standardization and an efficient workflow.

...This action is another in a series of steps EPA is taking to implement the Prevention of Significant Deterioration (PSD) program for greenhouse gas (GHG)-emitting sources. EPA is finalizing its proposed rulemaking to narrow its previous approval of State Implementation Plan (SIP) PSD programs in 24 states that apply to GHG-emitting sources. Specifically, EPA is withdrawing its previous approval of those programs to the extent they apply PSD to GHG-emitting sources below the thresholds in the final Tailoring Rule, which EPA promulgated by Federal Register notice dated June 3, 2010. Having narrowed its prior approval, EPA asks that each affected state withdraw from EPA consideration the part of its SIP that is no longer approved. The states for whose SIPs EPA is narrowing approval are: Alabama, California, Colorado, Georgia, Indiana, Iowa, Louisiana, Maine, Maryland, Mississippi, Missouri, New Hampshire, New Mexico, North Carolina, Ohio, Oklahoma, Rhode Island, South Carolina, South Dakota, Tennessee, Utah, Vermont, Virginia, and Wisconsin.

TRI: Growing pains

DOE Office of Scientific and Technical Information (OSTI.GOV)

Fairley, P.

1996-06-12

The 1994 toxics release inventory (TRI), scheduled to be released this week by EPA, will be the last before an aggressive expansion mapped out by EPA Administrator Carol Browner. By August 1, facilities must report on emissions and transfers of about 280 chemicals that were added to TRI in November 1994, nearly doubling the list. The changes could greatly increase the chemical industry`s TRI numbers, and there is more to come. This summer EPA is expected to formally propose extending TRI to nonmanufacturing facilities, such as power plants and airports. President Clinton has ordered EPA to expedite consideration of phasemore » III of Browner`s expansion: chemical use reporting under TRI.« less

78 FR 9281 - Regulation of Fuels and Fuel Additives: 2013 Renewable Fuel Standards

Federal Register 2010, 2011, 2012, 2013, 2014

2013-02-07

...Under section 211(o) of the Clean Air Act, the Environmental Protection Agency is required to set the renewable fuel standards each November for the following year. In general the standards are designed to ensure that the applicable volumes of renewable fuel specified in the statute are used. However, the statute specifies that EPA is to project the volume of cellulosic biofuel production for the upcoming year and must base the cellulosic biofuel standard on that projected volume if it is less than the applicable volume set forth in the Act. EPA is today proposing a projected cellulosic biofuel volume for 2013 that is below the applicable volume specified in the Act. EPA is proposing that the applicable volumes of advanced biofuel and total renewable fuel would remain at the statutory levels for 2013. Finally, today's action also proposes annual percentage standards for cellulosic biofuel, biomass-based diesel, advanced biofuel, and renewable fuels that would apply to all gasoline and diesel produced or imported in year 2013.

2012-05-04

...EPA proposes to approve State Implementation Plan (SIP) revisions submitted by the Maryland Department of the Environment (MDE). These revisions approve specific provisions of a 2011 Consent Decree between MDE and GenOn to reduce particulate matter (PM), sulfur oxides (SOX), and nitrogen oxides (NOX) from the GenOn Chalk Point generating station (Chalk Point). These revisions also remove the 1978 and 1979 Consent Orders for the Chalk Point generating station from the Maryland SIP as those Consent Orders have been superseded by the 2011 Consent Decree. In the Final Rules section of this Federal Register, EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this action, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time.

Continuous ultrasound-assisted extraction of hexavalent chromium from soil with or without on-line preconcentration prior to photometric monitoring.

PubMed

Luque-García, J L; Luque de Castro, M D

2002-08-01

A continuous ultrasound-assisted extractor was coupled to a photometric detector in order to obtain a fully automated approach for the determination of CrVI in soil. The use of a flow injection (FI) manifold as interface between the extractor and the photometric detector allowed the monitoring of CrVI after extraction in a continuous manner. The coloured complex formed between 1,5-diphenylcarbazide (DPC) and CrVI was used as recommended in EPA method 7196A because it is one of the most sensitive and selective reactions for CrVI determination. A preconcentration minicolumn packed with a strong anion-exchange resin was placed between the extractor and the detector, providing a more sensitive method. The linear dynamic ranges were 1-10 and 0.25-7.5 mg l-1 for the methods without (method A) and with preconcentration (method B), respectively. The limits of detection were 4.52 ng for method A and 1.23 ng for method B. Both methods were applied to a natural contaminated soil and the results obtained agreed well with those obtained by the reference EPA method 3060A. The influence of different amounts of CrIII in the samples was also studied and the results showed that the proposed methods did not disturb the original species distribution.

REVIEW OF DRAFT REVISED BLUE BOOK ON ESTIMATING ...

EPA Pesticide Factsheets

In 1994, EPA published a report, referred to as the “Blue Book,” which lays out EPA’s current methodology for quantitatively estimating radiogenic cancer risks. A follow-on report made minor adjustments to the previous estimates and presented a partial analysis of the uncertainties in the numerical estimates. In 2006, the National Research Council of the National Academy of Sciences released a report on the health risks from exposure to low levels of ionizing radiation. Cosponsored by the EPA and several other Federal agencies, Health Risks from Exposure to Low Levels of Ionizing Radiation BEIR VII Phase 2 (BEIR VII) primarily addresses cancer and genetic risks from low doses of low-LET radiation. In the draft White Paper: Modifying EPA Radiation Risk Models Based on BEIR VII (White Paper), ORIA proposed changes in EPA’s methodology for estimating radiogenic cancers, based on the contents of BEIR VII and some ancillary information. For the most part, it proposed to adopt the models and methodology recommended in BEIR VII; however, certain modifications and expansions are considered to be desirable or necessary for EPA’s purposes. EPA sought advice from the Agency’s Science Advisory Board on the application of BEIR VII and on issues relating to these modifications and expansions in the Advisory on EPA’s Draft White Paper: Modifying EPA Radiation Risk Models Based on BEIR VII (record # 83044). The SAB issued its Advisory on Jan. 31, 2008 (EPA-SAB-08-

To minimize the risk of cardiovascular disease (CVD), most dietary guidelines have recommended consuming 500 mg/day of eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) or two servings of oily fish/week. The sum of percent EPA and DHA in red blood cell (RBC) total fatty acids-termed the omega-3 index-has been proposed as a biomarker for assessing the risk of death from CVD. The omega-3 indices of ≤4, >4 to <8 and ≥8 % have been proposed to be associated with high, intermediate and low CVD risks, respectively. In this study, we determined the EPA + DHA intake level and the omega-3 index of South Asian Canadians (SAC; n = 308) and white Canadians (WC; n = 341) age 20-79 years living in the National Capital Region of Canada. The mean EPA + DHA intake levels were 569 ± 571 mg/day for SAC and 684 ± 865 mg/day for WC and 46 % of SAC and 43 % of WC met the recommended EPA + DHA intake level of 500 mg/day. The mean omega-3 indices were 6.6 and 5.9 % for SAC and WC respectively. The suggested cardio-protective target level for the omega-3 index of ≥8 % was observed only in 19.8 % of SAC and in 9.4 % of WC subjects. The majority of the participants (74.4 % of SAC and 82.7 % of WC) were in the >4 to <8 % range. These results suggest that although study participants' dietary intake of EPA + DHA is adequate, this intake was not sufficient to provide an omega-3 index that is considered cardio-protective.

The purpose of this paper is to describe multiple studies of wind and solar integration that have found CO 2 reductions of approximately 30%. These studies can be viewed in several ways, including as viable paths to compliance with the EPA rule, alternative ''bookend cases'' to compare to compliance based largely on natural gas, or something in between. The studies in this paper represent a body of work that can help inform the public discussion surrounding the cost and reliability impacts of complying with the proposed EPA CPP.

Section 1 provides a general description of how the individual treatment technology and regulatory option costs were developed. In Sections 2 through 4, EPA describes the development of costs for each of the wastewater and sludge treatment technologies. In Section 5, EPA presents additional compliance costs to be incurred by facilities, which are not technology specific. These additional items are retrofit costs, monitoring costs, RCRA permit modification costs, and land costs.

A System Dynamics Model for Integrated Decision Making ...

EPA Pesticide Factsheets

EPA’s Sustainable and Healthy Communities Research Program (SHC) is conducting transdisciplinary research to inform and empower decision-makers. EPA tools and approaches are being developed to enable communities to effectively weigh and integrate human health, socioeconomic, environmental, and ecological factors into their decisions to promote community sustainability. To help achieve this goal, EPA researchers have developed systems approaches to account for the linkages among resources, assets, and outcomes managed by a community. System dynamics (SD) is a member of the family of systems approaches and provides a framework for dynamic modeling that can assist with assessing and understanding complex issues across multiple dimensions. To test the utility of such tools when applied to a real-world situation, the EPA has developed a prototype SD model for community sustainability using the proposed Durham-Orange Light Rail Project (D-O LRP) as a case study.The EPA D-O LRP SD modeling team chose the proposed D-O LRP to demonstrate that an integrated modeling approach could represent the multitude of related cross-sectoral decisions that would be made and the cascading impacts that could result from a light rail transit system connecting Durham and Chapel Hill, NC. In keeping with the SHC vision described above, the proposal for the light rail is a starting point solution for the more intractable problems of population growth, unsustainable land use, environmenta

Three representatives of the Environmental Protection Agency (EPA) testified in response to questions over the agency's apparent approval of the land disposal of toxic materials in contradiction to the ban implicit in the Hazardous and Solid Waste Amendments of 1984. In new regulations, EPA interprets the ban as applying only when migration of toxic materials exceeds its screening levels. EPA also cites its screening levels to place a cap on waste treatment. At issue was EPA's effort to avoid the mandate of the 1984 legislation and its acceptance of screening levels which may assume a lower threat than actually exists.more » EPA representatives explained the rulemaking, and defended the use of screening levels as a basis for treatment and exemption. Additional material submitted for the record by the agency and by the House committee follows the testimony.« less

The Effects of EPA, DHA, and Aspirin Ingestion on Plasma Lysophospholipids and Autotaxin

SUMMARY Lysophophatidylcholine (LPC) and lysophosphatidic acid (LPA) are potent lysolipid mediators increasingly linked with atherosclerosis and inflammation. A current model proposing that plasma LPA is produced when LPC is hydrolyzed by the enzyme autotaxin has not been rigorously investigated in human subjects. We conducted a clinical trial of eicosapentaenoic acid/docosahexaenoic acid (EPA/DHA) and aspirin ingestion in normal volunteers. Fasting blood samples were drawn at baseline and after 4-week supplementation with EPA/DHA (3.4 g/d) with and without aspirin (650 mg). Plasma LPC and LPA species and autotaxin activity were measured. EPA-LPC and DHA-LPC concentrations increased significantly with EPA/DHA supplementation whereas EPA- and DHA-LPA did not. Autotaxin activity was unaffected by any treatment, and aspirin had no effect on any endpoint. Taken together, our data demonstrate that plasma LPC, but not LPA, species can be dynamically regulated by dietary supplementation, and argue against a simple model of LPA generation via LPC hydrolysis.

Federal Register 2010, 2011, 2012, 2013, 2014

2012-04-02

...The Agency is proposing to amend the Toxic Substances Control Act (TSCA) section 5(a) Significant New Use Rule (SNUR), for certain polybrominated diphenylethers (PBDEs) by: Designating processing of six PBDEs, or any combination of these chemical substances resulting from a chemical reaction, as a significant new use; designating manufacturing, importing, and processing of a seventh PBDE, decabromodiphenyl ether (decaBDE) for any use which is not ongoing after December 31, 2013, as a significant new use; and making inapplicable the article exemption for SNURs for this action. A person who intends to import or process any of the seven PBDEs included in the proposed SNUR, as part of an article for a significant new use would be required to notify EPA at least 90 days in advance to ensure that the Agency has an opportunity to review and, if necessary, restrict or prohibit a new use before it begins. EPA is also proposing a test rule under TSCA that would require any person who manufactures or processes commercial pentabromodiphenyl ether (c-pentaBDE), commercial octabromodiphenyl ether (c-octaBDE), or commercial decaBDE (c-decaBDE), including in articles, for any use after December 31, 2013, to conduct testing on their effects on health and the environment. EPA is proposing to designate all discontinued uses of PBDEs as significant new uses. The test rule would be promulgated if EPA determines that there are persons who intend to manufacture, import, or process c-pentaBDE, c-octaBDE, or c-decaBDE, for any use, including in articles, after December 31, 2013.

Cord Wood Testing in a Non-Catalytic Wood Stove

DOE Office of Scientific and Technical Information (OSTI.GOV)

Butcher, T.; Trojanowski, R.; Wei, G.

EPA Method 28 and the current wood stove regulations have been in-place since 1988. Recently, EPA proposed an update to the existing NSPS for wood stove regulations which includes a plan to transition from the current crib wood fuel to cord wood fuel for certification testing. Cord wood is seen as generally more representative of field conditions while the crib wood is seen as more repeatable. In any change of certification test fuel, there are questions about the impact on measured results and the correlation between tests with the two different fuels. The purpose of the work reported here ismore » to provide data on the performance of a noncatalytic stove with cord wood. The stove selected has previously been certified with crib wood which provides a basis for comparison with cord wood. Overall, particulate emissions were found to be considerably higher with cord wood.« less
