On July 9, 1970, Nixon proposed an executive reorganization that consolidated many environmental responsibilities of the federal government under one agency, a new Environmental Protection Agency.[21] This proposal included merging antipollution programs from a number of departments, such as the combination of pesticide programs from the United States Department of Agriculture, Department of Interior, and U.S. Department of Interior.[22] After conducting hearings during that summer, the House and Senate approved the proposal. The EPA was created 90 days before it had to operate,[23] and officially opened its doors on December 2, 1970. The agencys first Administrator, William Ruckelshaus, took the oath of office on December 4, 1970.[11] In its first year, the EPA had a budget of $1.4 billion and 5,800 employees.[22] At its start, the EPA was primarily a technical assistance agency that set goals and standards. Soon, new acts and amendments passed by Congress gave the agency its regulatory ...

118. Entergys argument concerning the permitting process presents a closer question, but it is ultimately not persuasive and does not undermine our conclusion that section 316(b), on its face, applies to existing facilities. The textual basis for the EPA to regulate cooling water intake structures during the periodic permitting process applicable to the discharge of pollutants is not immediately apparent. Section 402 conditions the issuance of a permit on the circumstance that a discharge will meet . . . all applicable requirements under sections 1311..[and] 1316. CWA § 402(a)(1), 33 U.S.C. § 1342(a)(1) (emphasis added). While the Phase II requirements are requirements under sections 301 and 306, they do not apply to the discharge of pollutants, and section 402 says nothing about conditioning a permit on compliance with other requirements of sections 301 and 306, i.e., requirements not relating to the discharge of pollutants. Despite this textual hiccup, the EPAs decision to use the ...

In order to assess the seasonal variations, potential sources, and health risks of heavy metals in fine particulate matter (PM2.5), PM2.5 samples (n = 96) were collected between March 2015 and February 2016 in Ningbo, China. Twelve heavy metals (Sb, As, Cd, Cr, Pb, Mn, Ni, Se, Tl, Al, Be, and Hg) found in the PM2.5 were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). We used enrichment factors and principal component analysis/absolute principal component scores (PCA/APCS) to determine the sources of these heavy metals, and models from the United States Environmental Protection Agency (EPA) to assess both the carcinogenic and non-carcinogenic risks to adults and children. Results showed that the average annual mass concentration of the PM2.5 was 62.7 µg m-3, which exceeded the limit specified in the Chinese National Ambient Air Quality Standards (NAAQS). The average annual concentrations of the Pb, Cd, and As were 57.2 ng m-3, 1.5 ng m-3, and 4.7 ng m-3, respectively, which were below

The Cross-State Air Pollution Rule (CSAPR) is a ruling by the United States Environmental Protection Agency (EPA) that requires member states of the United States to reduce power plant emissions that contribute to ozone and/or fine particle pollution in other states. The EPA describes this rule as one that protects the health of millions of Americans by helping states reduce air pollution and attain clean air standards. The CSAPR requires 23 United States states to reduce their annual emissions of sulfur dioxide (SO2) and nitrous oxides (NOx) to help downwind states attain the 24-hour National Ambient Air Quality Standards, and 25 states to reduce ozone season nitrous oxide emissions to help downwind states attain the 8-hour NAAQS. The states that are required to reduce sulfur dioxide emissions are divided into two groups, both of which must reduce their emissions in 2012. Group 1 is required to make additional emissions reductions by 2014. The CSAPR has been defended by environmental groups ...

The United States Environmental Protection Agency (EPA) published a May 13th Federal Register Notice stating that it is proposing to amend the…

The United States Government realized long ago the importance of protecting lakes, streams and rivers from pollutants. In 1948 Congress passed the Federal Water Pollution Control Act. They amended it in 1972 and again in 1977, renaming it the Clean Water Act. The Clean Water Act enables the United States Environmental Protection Agency to enforce water quality and pollution control standards. Responsibility for enforcing these standards was then passed onto each individual state.. In Illinois, legislation was created to specifically state that water supply officials are responsible for protecting their water mains from connections that have the potential to allow the backflow of contaminants into their respective distribution systems. The City of Evanston is required by state law to enforce Illinois Environmental Protection Agency (IEPA) and the Illinois Department of Public Health (IDPH) rules and regulations governing this legislation, along with our own local code.. ...

Toledo, OH - The Environmental Law & Policy Center (ELPC) today filed a new related lawsuit in the United States District Court for the Northern District of Ohio challenging the United States Environmental Protection Agencys approval of an Ohio EPA July 2018 report as legally inadequate. The Ohio EPAs 2018 report provided no effective plan for reducing phosphorus pollution into western Lake Erie which is now designated as impaired waters under the Clean Water Act.. ELPC and co-plaintiff Advocates for a Clean Lake Erie (ACLE) are seeking a judicial remedy providing a compliance plan to require progress on a specific timeline to reduce phosphorus pollution in western Lake Erie by 2025, and provide for public accountability. Phosphorus in manure and fertilizer runoff from agricultural sources is the principal cause of harmful algal blooms that have plagued Lake Erie for many years.. The Clean Water Act provides a specific legal pathway to reduce phosphorus pollution causing harmful algae ...

The scope of the Clean Water Act is yet again in flux. In January 2020, the Trump Administration meaningfully restricted what bodies of water are protected under the Clean Water Act by narrowing the Acts definition of waters of the United States (WOTUS). In doing so, the Trump administrations rule removed federal protections for about 25% of waters that would otherwise be afforded protection.1. It comes as no surprise that the Biden Administration aims to revoke this Trump-era regulation. In fact, the United States Environmental Protection Agency (EPA) and Army Corps of Engineers commenced a formal rulemaking process to revoke and replace the Trump-era rule on June 9, 2021.2. But change came sooner than expected. On August 30, 2021, Judge Rosemary Marquez of the District of Arizona struck down the Trump-era WOTUS rule.3 Judge Marquez vacated and remanded the Trump Administrations WOTUS rule because it conflicts with established science … and weakens protection of the nations waters in ...

When is Earth Day and what exactly is it all about? Earth Day is officially April 22nd and is a day to celebrate Mother Earth and draw attention to environmental issues. The first Earth Day was the brainstorm of Senator Gaylord Nelson, a U.S. Senator from Wisconsin, which began as an idea after witnessing the Cuyahoga River going up in flames in 1968 for the second time. The first Earth Day received support from both political parties - Republicans and Democrats, as well as rich and poor, tycoons and labor workers. It led to the formation of the United States Environmental Protection Agency (EPA) that same year, as well as the passage of the Clean Water Act, Clean Air Act, and the Endangered Species Act. Earth Day has been celebrated every year since 1970 and in 1990, the event went global. Earth Days purpose of encouraging social and political action by drawing attention to the environmental cause remains unchanged.. ...

Glyphosate has a United States Environmental Protection Agency‎ Toxicity Class of III in 1993,[34] . It has been rated as class I (Severe) for eye irritation. Glyphosate is being evaluated for effects to unborn fetuses and their development. It is currently on the USEPA Endocrine Disrupter Screening list, published in 2007.[36][37]. Outside its intended use, glyphosate can be lethal. For example, with intentional poisonings there is approximately a 10% mortality for those ingesting glyphosate, compared to 70% for those ingesting paraquat.[38]. Laboratory toxicology studies suggest that other ingredients combined with glyphosate may have greater toxicity than glyphosate alone. For example, a study comparing glyphosate and Roundup found that Roundup had a greater effect on aromatase than glyphosate alone.[9]. Statistics from the California Environmental Protection Agencys Pesticide Illness Surveillance Program indicate that glyphosate-related incidents are one of the highest reported of all ...

One component of the United States Environmental Protection Agencys (EPA) study of the potential impacts of hydraulic fracturing on drinking water resources is prospective case studies, which are being conducted to more fully understand and assess if and how site specific hydraulic fracturing practices may impact drinking water resources.1 The retrospective case studies, addressed in a separate EPA presentation for this workshop, focus on investigating and assessing reported instances of drinking water contamination in areas where hydraulic fracturing activities have already occurred. The prospective case studies will be forward looking and will allow for the collaborative design and development of a research program that will include sampling and characterization of the site before, during and after drilling, injection of the fracturing fluid, flowback and production.. ...

Methods to collect water samples and analyze them for Cryptosporidium and Giardia have improved dramatically since 1992. Currently, we use the United States Environmental Protection Agency (EPA) approved Method 1623.1 to analyze samples. Prior to switching to new and improved methods, we conduct validation studies to demonstrate that new methods recommended by the EPA provide more accurate and consistent results. Since recoveries from one method to the next have improved, results from the different methods may not be comparable. For reference, our method history includes ASTM D-19 P229 from 1992 to 1998, EPA ICR method from 1999 to 2000, and EPA 1623 from October 2001 to 2015. Our current method, EPA Method 1623.1, was implemented in April 2015. This method provides significantly better recovery and identification of Giardia and Cryptosporidium. Our Pathogen Laboratory is approved by the State of New Hampshire to perform Method 1623.1 under the Laboratory Quality Assurance Evaluation Program for ...

The United States Environmental Protection Agency (US EPA) has been in the process of conducting a reassessment of the health damaging effects of dioxin exposure for the past decade. In 2000, the agency published a draft risk characterization that attributed a 1 in 1000 upper-bound excess cancer risk to average background levels of dioxin exposure.. Several federal government agencies, including: the US Department of Agriculture, the US Food and Drug Administration, the US Department of Health and Human Services, and the EPA, are represented on the Interagency Working Group on Dioxin. These parties have developed a paper entitled Questions and Answers About Dioxins that provides basic information for the public on the matter of exposure and adverse health effects..

The critical message of this report is that current levels of dioxins and dioxin-like ...

Recently, the United States Environmental Protection Agency decided to regulate perchlorate under the Safe Drinking Water Act. Recent research has shown perchlorate to have potential endocrine disrupting effects in humans, with possible effects on the thyroid. Given perchlorate levels in water, the EPA has determined that there is an opportunity for health risk due to perchlorate levels.

Ultrafine particulate matter (UFP) refers to particles with diameters less than 0.1 microns. They have known adverse health effects. Currently they are not regulated by the United States Environmental Protection Agency. Thus air districts are not required to monitor UFP. The Bay Area Air Quality Management District recognizes that monitoring UFP levels in the Bay Area, identifying their emission sources and assessing their health impacts are important. In 2011, the Air District established a comprehensive program to study UFP. As part of this program, the Air District began making measurements at four air monitoring stations - Santa Rosa (now Sebastopol), San Pablo, Livermore, and Redwood City. The number of measurement sites has since increased to include Oakland (Laney College) and San Jose, with Berkeley expected to be online soon. These newer locations are part of a near-roadway measurement effort. At each station, the number of particles in a specified volume of air is counted every ...

If one was really interested in determining the body burden of mercury they would perform the urinary porphyrin profile analysis (UPPA). Porphyrins are precursors to heme, the oxygen carrying component of blood. Mercury inhibits the conversion of specific porphyrins to heme. This test is backed by decades of published research. Recently it was shown in two published, peer-reviewed studies, that mercury inhibited porphyrins were significantly higher in autistic patients when compared to age matched controls (1)(2). The other way to test for mercury in the body is by using a provoking agent and measuring mercury in the urine. ...... Dr. Fombonne refers to the amount of mercury in vaccines as trace. Again, if he were a toxicologist or chemist, he would realize that the concentration of mercury in a multi-dose vaccine vial is 250 times higher than what the United States Environmental Protection Agency (EPA) classifies as hazardous waste..

The United States Environmental Protection Agency (EPA) finally broke their silence on the Flint tragedy two weeks ago, when it quietly released a memo answering the simple question: Was MDEQ wrong, when it tried to leave Flints children completely unprotected from lead in water hazards for close to two years?. As demonstrated by e-mails from a FLINTWATERSTUDY.org Freedom of Information Act (FOIA) request, MDEQ did not want to be bothered with installing corrosion control in Flint before the new Karegnondi Water Authority pipeline came online in 2016. Even after MDEQ realized Flint children were being lead poisoned from the tap water in early 2015 and were told by EPA their plans were illegal, they worked doggedly to do nothing at all. A month ago MDEQ admitted it had made mistakes. But the EPA Office of Water memo now bails out MDEQ on their actions in Flint. According to EPA, MDEQ cannot really be blamed because ….there are differing possible interpretations of the LCR…which may have ...

Toxicogenomics is a field of science that deals with the collection, interpretation, and storage of information about gene and protein activity within particular cell or tissue of an organism in response to toxic substances. Toxicogenomics combines toxicology with genomics or other high throughput molecular profiling technologies such as transcriptomics, proteomics and metabolomics[1][2]. Toxicogenomics endeavors to elucidate molecular mechanisms evolved in the expression of toxicity, and to derive molecular expression patterns (i.e., molecular biomarkers) that predict toxicity or the genetic susceptibility to it.. This broad definition is supported by the United States Environmental Protection Agency stating that the term genomics encompasses a broader scope of scientific inquiry and associated technologies than when genomics was initially considered. A genome is the sum total of all an individual organisms genes. Thus, genomics is the study of all the genes of a cell, or tissue, at the DNA ...

IDEM began blue-green algae sampling the week of May 15 and will end the week of August 28. IDEM samples for blue-green algae and analyzes those samples for the type and quantity of blue-green algae present and for the following toxins which may be produced by certain types of blue-green algae: microcystin, cylindrospermopsin (only done if species that produce it are present) and anatoxin-a. For protection of human health from exposure to the algae and any of the toxins, cyanobacteria will be compared to the World Health Organization (WHO) and United States Environmental Protection Agency (EPA) guidelines. WHO guidelines recommend using an action level of 100,000 cells/ml of cyanobacteria to post recreational advisory signs. New USEPA guidelines for microcystins recommend posting recreational advisories at 4 μg/l and DNR will issue an additional advisory at 4μg/l. Swimming will be prohibited at 20 μg/l, consistent with WHO guidelines. DNR will use the USEPA recommended cylindrospermopsin ...

In assessing exposure to indoor air contaminants, the understanding of population water-use behavior for indoor water-use activities as a function of demographic characteristics is vital to obtaining realistic exposure estimates. In response to the need for more specific and usable population based water-use data for exposure modeling, new data sources have been analyzed. Frequencies, durations, volumes and flowrates of showers, baths, clothes washers, dishwashers, toilets and faucets are presented, derived from analyses of the National Human Activities Pattern Survey (NHAPS) database, the Residential End Uses of Water Study (REUWS) database, the Residential Energy Consumption Survey (RECS) as well as from current literature and manufacturer information. Distribution parameters for water use behaviors are identified for use as inputs for modeling exposure to water borne contaminants.

Less] For 20 years, many articles report the presence of new compounds, called emerging compounds, . . . [More] For 20 years, many articles report the presence of new compounds, called emerging compounds, in wastewater and aquatic environments. The US EPA (United States - Environmental Protection Agency) defines emerging pollutants as new chemicals without regulatory status and which impact on environment and human health are poorly understood. The objective of this work was to identify data on emerging pollutants concentrations in wastewater, in influent and effluent from wastewater treatment plants (WWTPs) and to determine the performance of sewage disposal. We collected 44 publications in our database. We sought especially for data on phthalates, Bisphenol A and pharmaceuticals (including drugs for human health and disinfectants). We gathered concentration data and chose 50 pharmaceutical molecules, six phthalates and Bisphenol A. The concentrations measured in the influent ranged from ...

The intertidal zone-a transitional boundary between terrestrial and marine environments-has important ecological functions, and receives polycyclic aromatic hydrocarbons (PAHs) from human activities, but how and to what extent anthropogenic factors influence the distribution of PAHs in this important niche remain largely unknown. Here we measured the distribution of United States Environmental Protection Agency priority PAHs in samples of intertidal sediments from across more than 4,500 km of Chinas coastline. The total PAH concentrations ranged from 2.3 to 1,031.7 ng g−1 sediment (dry weight) and all PAHs showed positive correlations with total organic carbon (TOC). TOC-normalized high-molecular-weight (HMW) PAH concentrations, but not TOC-normalized low-molecular-weight (LMW) PAHs, were positively correlated with TOC. Moreover, population size and economic development influenced TOC-normalized HMW PAH concentrations, whereas urbanization had a major influence on TOC-normalized LMW PAHs. Human

Recent research has emphasized the importance of using physical, chemical, and biological indicators of stream health for diagnosing impaired watersheds and their receiving water bodies. A multidisciplinary team at the University of Minnesota is carrying out research to develop a stream classification system for Total Maximum Daily Load (TMDL) assessment. Funding for this research is provided by the United States Environmental Protection Agency and the Minnesota Pollution Control Agency. One objective of the research study involves investigating the relationships between indicators of stream health and localized stream characteristics. Measured data from Minnesota streams collected by various government and non-government agencies and research institutions have been obtained for the research study. Innovative Geographic Information Systems tools developed by the Environmental Science Research Institute and the University of Texas are being utilized to combine and organize the data.

Effective and affordable arsenic removal from drinking water has become a significant issue recently. The United States Environmental Protection Agency (EPA) has promulgated a new maximum contaminant level (MCL) for arsenic in drinking water which will take effect in January 2004. The current arsenic MCL of 50 micrograms per liter (ugll) was set by the United sates Public Health Service in 1943 and has not been reduced in nearly 60 years. Arsenic has been linked to various types of cancers, prompting EPA to change the standard. Due to the fact many water systems, especially small water utilities serving less than 10,000 people, will be impacted by a reduced standard much research is currently being done to fmd treatment technologies affordable enough for small water systems to implement and maintain. Many small water utilities lack the financial and technical resources required to construct and maintain centrally located water treatment facilities capable of removing arsenic. For this reason, many small

Hundreds of studies have already demonstrated the severely deleterious health effects of living near radio and microwave broadcast towers. Also, review the information on irrelevance of present SAR standards. The United States Environmental Protection Agency (EPA) itself acknowledges that current Federal Communications Commission (FCC) radiation protection standards are inadequate and do not account for all possible harmful effects of RFR, in particular the non-thermal effects that are of particular relevance to the radiation utilized by WiFi. In a July 16, 2002 letter from Norbert Hankin of the EPAs Center for Science and Risk Assessment, Radiation Protection Division to Janet Newton, President of The EMR Network, Mr. Hankin writes: The FCCs current exposure guidelines, as well as those of the Institute of Electrical and Electronics Engineers (IEEE) and the International Commission on Non-Ionizing Radiation Protection, are thermally based, and do not apply to chronic, non-thermal exposure ...

Monday, November 15th, 2010 A growing number of governments, organizations, and authorities are recognizing multiple chemical sensitivity (MCS) as an illness induced by toxic substances.. MCS is an acquired illness that begins with a chemical poisoning event, either from an acute exposure or long-term chronic exposure to a toxic substance. Once the initial poisoning occurs, the condition is triggered by low-level exposure to airborne agents and other toxic substances such as perfumes, fragranced products, cleansers, pesticides, mold, solvents, and new building materials.. The United States Environmental Protection Agency defines MCS as a diagnostic label for people who suffer multi-system illnesses as a result of contact with, or proximity to, a variety of airborne agents and other substances.. MCS often becomes disabling because the triggering chemicals are pervasive in the everyday environment. Various governments, organizations, and authorities have recognized the serious nature of MCS and ...

Phthalates are endocrine disruptors frequently occurring in general and industrial environment and in may industrial products. Moreover, they are also suspected of being carcinogenic, teratogenic, and mutagenic and they show diverse toxicity profiles depending on their structures. The European Union and United States Environmental Protection Agency (US EPA) have included many phthalates into the list of priority substances with potentially endocrine disrupting action. Namely they are: dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), butylbenzyl phthalate (BBP), diethylhexyl phthalate (DEHP), di-iso-nonyl phthalates (DINP), di-iso-decyl phthalate (DIDP), di-n-decyl phthalate (DNDP), and dioctyl phthalate (DOP). There is an ever increasing demand for new analytical methods suitable for monitoring of different phthalates in various environmental, biological and other matrices. Separation and spectrometric methods are most frequently used. However, modern electroanalytical ...

The United States Environmental Protection Agency (EPA) has the authority to regulate the public water systems. The EPA does not have the jurisdiction to regulate private drinking water wells. This leaves approximately fifteen percent of the nations population without any regulation being held in place to protect their source of drinking water. With that fifteen percent of the US population having private wells for drinking water, it makes the number of people whose drinking water is unprotected by regulation at a little over 15 million US households. This concern is even more acute in areas with groundwater that is close to the surface. Delaware residents live in a region with low elevation which is very close to the coast with low elevation and the shallow groundwater makes us concern about contaminated well water even more intense. As one of the Water Resources Program partners, we have offered free Drinking Water Quality Clinics to local well owners over the past 4 years in Delaware State

In its assessment of chloramine toxicity to marine invertebrates, Environment Canada (the Canadian equivalent of the United States Environmental Protection Agency, EPA) determined the Estimated No-Effects Value (ENEV) based on this type of data to be 0.002 ppm-Cl for marine and estuarine environments.. How much chloramine should one allow into an aquarium? That, of course, depends on what is in the aquarium. In the absence of knowing the toxicity of chloramine to every inhabitant of the aquarium (or of even knowing the identity of every inhabitant), it seems prudent to have chloramine levels far below those where the most sensitive organisms are killed, and that chloramine concentration is somewhere well below 0.005 ppm-Cl. The value suggested by Environment Canada seems like a reasonable maximum. There is, however, substantial uncertainty in deciding exactly which levels are acceptable and which are not, since there is so little data available. Perhaps the acceptable levels for daily exposures ...

TY - JOUR. T1 - Bed bugs and possible transmission of human pathogens. T2 - a systematic review. AU - Lai, Olivia. AU - Ho, Derek. AU - Glick, Sharon. AU - Jagdeo, Jared. PY - 2016/10/1. Y1 - 2016/10/1. N2 - The global population of bed bugs (Cimex lectularius and Cimex hemipterus, family Cimicidae) has undergone a significant resurgence since the late 1990s. This is likely due to an increase in global travel, trade, and the number of insecticide-resistant bed bugs. The global bed bug population is estimated to be increasing by 100-500 % annually. The worldwide spread of bed bugs is concerning, because they are a significant socioeconomic burden and a major concern to public health. According to the United States Environmental Protection Agency, bed bugs are a pest of significant health importance. Additionally, 68 % of U.S. pest professionals reported that bed bugs are the most challenging pest to treat. Upwards of 45 disease pathogens have been reported in bed bugs. Recent studies report ...

AU - Dennehy, T. J.. AU - Liu, Y. B.. AU - Miller, E.. AU - Staten, R. T.. PY - 1999/1/1. Y1 - 1999/1/1. N2 - To delay evolution of pest resistance to transgenic cotton that produces Bacillus thuringiensis toxin Cry1Ac (Bt cotton), refuges composed of cotton that does not produce Cry1Ac (non-Bt cotton) are mandated by the United States Environmental Protection Agency. One critical assumption of this strategy is that susceptible adults emerging from non-Bt cotton refuges mate with resistant adults emerging from Bt cotton, which requires movement of adults between Bt cotton and non-Bt cotton. To better understand movements of pink bollworm, the key lepidopteran pest of cotton in Arizona, we analyzed the distribution of wild males and dispersal of sterile males during 1997 on a 259-ha block of a commercial farm ...

WASHINGTON (April 28, 2020) - Today, the U.S. Environmental Protection Agency (EPA) and State of Indiana announced that recent air monitoring data show the city of Indianapolis, and the areas of Muncie, Lake and Porter counties are meeting federal air quality standards.. EPA and the Indiana Department of Environmental Management (IDEM) are formally redesignating the Indianapolis area to attainment of the 2010 sulfur dioxide air quality standard, the Muncie area to attainment of the 2008 lead standard, and proposing to redesignate Lake and Porter counties to attainment for the 2008 ground-level ozone standard. Three years of air monitoring data show these areas now meet these National Ambient Air Quality Standards (NAAQS) set to protect public health. Under President Trumps leadership we are working hard to bring areas into attainment with our air quality standards, said EPA Administrator Andrew Wheeler. Todays action recognizes the fact that people in these counties in Indiana are now ...

The Environmental Protection Agency (EPA) implemented the 1-hour National Ambient Air Quality Standards (NAAQS) for ozone in 1990. Under this standard, the ozone threshold value was 125 parts per billion (ppb), measured as one-hour average concentration. An area met this ozone NAAQS if there were no more than three exceedances at any one monitor in the region in a three-year period.. Four counties in the North Central Texas (NCT) region were designated as nonattainment for the 1-hour ozone NAAQS in 1991. Those counties were Collin, Dallas, Denton, and Tarrant. On June 15, 2005, the 1-hour ozone NAAQS was revoked and replaced by the 8-hour ozone NAAQS. (see 1997 Ozone NAAQS).. On October 31, 2006, the region demonstrated attainment of the 1-hour ozone NAAQS , although it continues to be monitored due to EPAs anti-backsliding requirements. On October 16, 2008, the EPA issued a determination of attainment for the four one-hour nonattainment counties in NCT. ...

The core of the Administrators rationale for tightening the ozone National Ambient Air Quality Standards (NAAQS) that is articulated in the US Environmental Protection Agency (EPA) Proposed Rule (79 Fed. Reg. 75234), is based on clinical studies of lung function responses to various levels of ozone. The specific measurement of lung function discussed is forced expiratory volume in one second (FEV1), and FEV1 changes are the lung function impact for which the Health Risk and Exposure Assessment (HREA) document provides quantitative risk estimates under alternative ozone NAAQS levels.. Analysis by Dr. Anne E. Smith and Dr. Garrett Glasgow finds that there is a large degree of both statistical and model uncertainty in the lung function decrements reported in the HREA, and that uncertainty undercuts the confidence in the projected reductions in lung function impacts that are described in the Proposed Rule.. ...

The city of Shreveport, La., has agreed to make significant upgrades to reduce overflows from its sanitary sewer system and pay a $650,000 civil penalty to resolve Clean Water Act (CWA) violations stemming from illegal discharges of raw sewage, the Department of Justice and the U.S. Environmental Protection Agency (EPA) announced today. The state of Louisiana, a co-plaintiff in this case, will receive half of the civil penalty. When wastewater systems overflow, they can release raw sewage and other pollutants, threatening water quality and potentially contributing to disease outbreaks. To come into compliance with the CWA, the city estimates it will spend approximately $342 million over the next 12 years in order to improve the sewer systems condition. While the city upgrades the system, it will also implement a program for capacity management, operation, and maintenance to help reduce sanitary sewer overflows. The key provisions of this settlement will eliminate overflows of raw sewage in ...

On Wednesday, the US Environmental Protection Agency and the US Army Corps of Engineers issued the final Clean Water Rule defining waters of the United States subject to regulation under the Clean Water Act. The final rule comes more than a year after the agencies published a proposed rule, which resulted in approximately 400 public hearings and generated more than 1 million comments. After Supreme Court decisions in 2001 and 2006 created significant uncertainty regarding the scope of waters regulated under the Clean Water Act, the goal of the agencies rulemaking efforts was to clarify which waterbodies fall within the Clean Water Acts regulatory scheme.. According to EPA, the Clean Water Rule:. ...

The U.S. Environmental Protection Agency (EPA) is announcing a 60-day public comment period for the External Review Draft of ``Microbial Risk Assessment Guideline: Pathogenic Microorganisms with Focus on Food and in Water. EPA developed the Guideline in collaboration with the U.S. Department of Agriculture, Food Safety Inspection Service (USDA/FSIS) and with scientists from other Federal agencies. This draft document is being released solely for the purpose of seeking public comment prior to peer review. The document will undergo independent peer review during an expert peer review meeting, which will be convened, organized, and conducted by an EPA contractor in 2011. The date of the external peer review meeting will be announced in a subsequent Federal Register notice. All comments received by the docket closing date September 26, 2011 will be shared with the external peer review panel for their consideration. Comments received after the close of the comment period may be considered by the ...

The Environmental Protection Agency has proposed rules to strengthen the National Ambient Air Quality Standards for two primary pollutants under the Clean Air Act: sulfur dioxide and ozone pollution (smog).

The Environmental Protection Agency extends comment periods for proposed rules: Formaldehyde Emissions Standards for Composite Wood Products for 30 days, and Third Party Certification Framework for the Formaldehyde Standards for Composite Wood Products for 30 days. Public comments are now due October 9, 2013 and September 25, 2013, respectively. On June 10, 2013, EPA issued proposed rules in the Federal Register concerning formaldehyde emissions standards for composite wood products. Todays Federal Register notices extend the comment periods from September 9, 2013 to October 9, 2013 for the Formaldehyde Emissions standards for Composite Wood Products proposed rule, and from August 26th, 2013 to September 25, 2013 for the Third-Party Certification Framework for the Formaldehyde Standards for Composite Wood Products proposed rule. EPA had received numerous requests for an extension.. The proposed rule will implement the statutory formaldehyde emission standards for hardwood plywood, ...

SACRAMENTO - California Attorney General Xavier Becerra and the California Air Resources Board (CARB), leading a multistate coalition, filed comments demanding that the U.S. Environmental Protection Agency (EPA) withdraw its proposed rule delaying by four years implementation of a critical regulation that would reduce emissions from landfills. Landfills are the third-largest source of methane emissions - a pollutant with a global warming potential that is 84 times more potent than carbon dioxide over a 20-year timeframe.

A Virginia Tech graduate student has received a U.S. Environmental Protection Agencys Science to Achieve Results or STAR program fellowship for outstanding environmental research.. Laura Schoenle of Buffalo, New York, a Ph.D. student in biological sciences in the College of Science, received the award for studying stress hormones and disease in red-winged blackbirds. Schoenle is also a fellow in the new Interfaces of Global Change interdisciplinary graduate education program funded by the Graduate School with support from the Fralin Life Science Institute.. Human-induced factors including climate change, habitat degradation, and pollution can affect the health of birds. Schoenle is interested in how mercury contamination affects the levels of a stress hormone called glucocorticoid in birds. High levels of this stress hormone tells you that a bird is under resource demand, and therefore might be more susceptible to disease, said Schoenle, who is also an Institute for Critical Technology and ...

The Environmental Protection Agency said Aug. 23 that it will delay finalizing its air quality standards for ozone until October so it can continue to analyze information it received during the public comment period. Issuing of the final national ambient air quality standards for ozone had been expected in August. EPA remains committed to protecting public health from the dangers of ground-level ozone, a key component of smog, EPA said in its statement. We are continuing to carefully consider the proposed options and the information we received during the public comment period on the January 2010 proposal. There will be a slight delay in finalizing our decision on any new ozone standards. We expect to finalize the standards towards the end of October 2010. We have spoken with the litigants and have updated the court on our status. EPA agreed to voluntarily reconsider the ozone air standards, set in 2008, after several states and environmental groups filed lawsuits in the U.S. Court of ...

Air quality models are increasingly used to develop estimates of dry and wet deposition of sulfate and nitrate in watersheds (because of lack of measurements) in an effort to determine the acidifying deposition load into the aquatic systems. These models need to be rigorously evaluated to ensure that one can rely on the modeled quantities instead of the measured quantities. In the United State (U.S.), these models have been proposed for use in establishing national standards based on modeled quantities. The U.S. Environmental Protection Agency (EPA) is considering aquatic acidification as the main ecological endpoint of concern in determining the secondary national ambient air quality standards for nitrogen oxides and sulfur oxides. Acidification is tied to depositions of sulfur and nitrogen, which are linked to ambient concentrations of the elements. As EPA proposes to use a chemical transport model in linking deposition to ambient concentration, it is important to investigate how the currently used

Although it has been known for more than half a century that plants release a plethora of non-methane hydrocarbons (NMHCs), it was not until the mid-1980s that scientists firmly established the links between ozone formation/destruction and ambient NMHCs. Owing to their high reactivity, it is now well known that NMHCs can augment ozone formation in environments rich in nitrogen oxides. In jurisdictions such as the northeastern part of North America, this is a serious environmental issue as summer-time ozone levels frequently exceed the National Ambient Air Quality Standard set by the U.S. Environmental Protection Agency. I have conducted research to separate the contribution of biogenic precursors to ozone formation. My most active research area concerns field and theoretical investigations involving turbulent transport theory and chemical processing of biogenic NMHCs inside and above forests. My early work on this topic involved the development of measurement protocols to investigate the ...

Conservation groups rally together to voice support for fish and wildlife habitat, wetlands, and headwater streams. Conservation groups are opposing the Administrations rollback of the 2015 Clean Water Rule, which was finalized today. The Administrations action will leave roughly 50 percent of wetlands and 60 percent of stream miles across the country vulnerable to pollution and destruction. The 2015 Clean Water Rule had clarified longstanding Clean Water Act protections for millions of acres of wetlands and many headwater streams that protect communities from flooding, contribute to the drinking water supplies of one in three Americans, and provide essential fish and wildlife habitat that supports a robust outdoor recreation economy worth $887 billion.. Sportsmen and women are outside every day experiencing the benefits of clean water, says Whit Fosburgh, president and CEO of the Theodore Roosevelt Conservation Partnership. Rolling back these protections for wetlands and headwater streams ...

A. Bryan Endres and Jonathan Coppess • conservation and other • A previous series of articles discussed water quality and environmental issues relevant, or potentially of concern, to agriculture. In a return to the topic, recent developments on matters of water quality will be discussed in two articles. On February 14, 2019, the Environmental Protection Agency and the Army Corps of Engineers published a proposed rule for defining the waters of the United States for purposes of the Clean Water Act; the proposed rule is open for public comment until April 15, 2019. Additionally, a recent decision by the Ninth Circuit Court of Appeals on a case out of Hawaii will soon be heard by the Supreme Court regarding permitting under the Clean Water Act. This article reviews the lawsuit under the Clean Water Act that will soon be heard by the Supreme Court.

The average PM2.5 level in 78 restaurants before the implementation of the SFA law was 126 μg/m3. The level was five times higher than the WHO guideline level for 24 h exposure of 25 μg/m3 (WHO, 2006). The level was also 3.6 times higher than the health-based 24 h National Ambient Air Quality Standard (NAAQS) for outdoor air average of 35 μg/m3 set by the US EPA on 14 December 2012.17. Indoor air quality in 77 restaurants was significantly improved and PM2.5 average level was reduced by 90.6% after the implementation of the Michigan SFA law. The average postlaw indoor PM2.5 level of 11.8 μg/m3 was below both WHO guideline and the NAAQS. Compliance with SFA law is critical to achieving the goal of eliminating exposure to SHS. All restaurants measured in this study complied with the SFA law. The findings in this study indicate that a state-wide law to eliminate smoking in enclosed workplaces and public places substantially reduced PM2.5 levels in all monitored Michigan restaurants, changing ...

Today we review a nation-wide assessment of the impact of fireworks on local air quality in the USA. Results indicate tht the particulates emitted during these displays increased particulate pollution by 42% on average, although individual cities had increases of 400% temporarily and other venues such as the International Fireworks Competition in Montreal and New Years Eve in Germany showed increases of 40 to 50 times more. As the particulate emissions from these eruptions last only for a few hours, the higher pollution levels are not counted in either the national air quality regulations (such as National Ambient Air Quality Standards for PM2.5 in the USA or European Union PM10 air quality standard). Clearly short term air quality forecasts could be improved using the results from this study. In addition, spectators would be well advised to stay upwind from the fireworks to avoid polluted air and the health impacts that may result from breathing it ...

Nitrogen dioxide (NO2) is one of a group of highly reactive gasses known as oxides of nitrogen, or nitrogen oxides (NOx). Other nitrogen oxides include nitrous acid and nitric acid. While EPAs National Ambient Air Quality Standard covers this entire group of NOx, NO2 is the component of greatest interest and the indicator for the larger group of nitrogen oxides. NO2 forms quickly from emissions from cars, trucks and buses, power plants, and off-road equipment. In addition to contributing to the formation of ground-level ozone, and fine particle pollution, NO2 is linked with a number of adverse effects on the respiratory system.. EPA first set standards for NO2 in 1971, setting both a primary standard (to protect health) and a secondary standard (to protect the public welfare) at 0.053 parts per million (53 ppb), averaged annually. The Agency has reviewed the standards twice since that time, but chose not to revise the annual standards at the conclusion of each review. In January 2010, EPA ...

In this research, we investigated the public health risks associated with atmospheric exposure to PM2.5 for different subpopulations (black, white, Hispanic, youth, adults, and elderly) in the Washington, DC area. Washington, DC has long been considered a non-healthy place to live according to the American Lung Association due to its poor air quality. This recognition clearly includes the negative PM-related human health effects within the region. Specifically, DC fine particulate matter (PM2.5) [or particulate matter with an aerodynamic diameter less than 2.5 μm] poses notable health risks to subpopulations having an annual mean value of 16.70 μg/m3 during the years 1999-2004, exceeding the EPA National Ambient Air Quality Standard (NAAQS) of 15 μg/m3. Incessant exposure to significant levels of PM has previously been linked to deleterious health effects, such as heart and lung diseases. The environmental quality and public health statistics of Washington, DC indicate the need for higher-resolution

On October 23-24, 2007, subject matter experts on particulate matter (PM) gathered at Allerton Park in Monticello to exchange ideas and experiences in project level hotspot analysis of PM, including monitoring and compliance. The attendees included staff from five Midwestern state Departments of Transportation (DOTs), metropolitan planning organizations, the U.S. EPA, the Illinois EPA, University faculty, and the FHWA. Particulate matter is a generic term for a broad class of chemically and physically diverse substances that exist as discrete particles (liquid droplets or solids) over a wide range of sizes. It is emitted into the air through combustion exhausts or mechanical wear-and-tear from cars and trucks, power plants and factories, and construction sites. A hot-spot analysis is an estimation of likely future localized pollutant concentrations and a comparison of those concentrations to the National Ambient Air Quality Standards (NAAQS) set by the U.S. EPA. In general, the peer exchange ...

To investigate trace element pollution of PM10 in urban Chengdu, a Southwest megacity of China, as well as to assess the human health risks caused by exposure to PM10, we analyzed ambient PM10 samples collected at an urban site in Chengdu from November, 2014 to October, 2015. The annual mean concentration of PM10 in the sampling period was 173.6 ± 77.9 µg m-3, which is 2.5 times higher than the national recommended standard of 70 µg m-3. The mean metals content in PM10 was in the following order: iron (Fe) > zinc (Zn) > titanium (Ti) > copper (Cu) > manganese (Mn) > lead (Pb) > barium (Ba) > chromium (Cr) > strontium (Si) > nickel (Ni) > arsenic (As) > vanadium (V) > antimony (Sb) > cobalt (Co) > cadmium (Cd) > bismuth (Bi). The concentration of As in PM10 was observed to be 2.9 times higher than the secondary level recommended by the China National Ambient Air Quality Standard (GB3095-2012), whereas the concentrations of other metals were within the limit

On April 1, 2009, the U.S. Supreme Court ruled in a series of cases -- Entergy v. EPA (07-588), PSEG Fossil LLC v. Riverkeeper Inc. (07-589) and Utility Water Act Group v. Riverkeeper Inc. (07-597) -- that the EPA may rely on cost-benefit analysis in setting the national performance standards, when applying the CWA to power plant cooling systems. [4] The CWA requires power plants that use at least 50 million gallons of water a day to generate steam for electricity to use the best technology available for minimizing adverse environmental impact cooling water intake structures. Justice Antonin Scalia wrote in the majority opinion that the CWA wording best technology available, even with the added specification for minimizing adverse environmental impact, does not unambiguously preclude cost-benefit analysis. [5] Legal Times called the ruling a pro-business decision, [6] but environmental groups pointed out that the ruling allowed, but did not mandate, that the EPA include a ...

It showed that both the taxi driver and the athlete suffered levels of exposure higher than the national standard ...

Air pollution in the capital Kathmandu and Terai area is particularly worrying. In the case of Kathmandu, major sources of air pollution are brick kilns, fume-spewing vehicles (vehicle registration in Bagmati Zone, which includes Kathmandu Valley, doubled in the past fiscal year according to the Department of Transport Management), street dust and burning of waste at home. These factors coupled with the Valleys bowl-like topography which traps heavy polluted air, means that for most days of the year, except for the rainy seasons, the air quality of Kathmandu Valley hits dangerous level - up to five times worse than the upper limit of the National Ambient Air Quality Standards guidelines according to Nepal Health Research Council (NHRC ...
