EPA Report Shows Progress in Reducing Urban Air Toxics Across the United States




WASHINGTON -
 Today, the U.S. Environmental Protection Agency (EPA) released the Second Integrated Urban Air Toxics Report to Congress - the final of two reports required under the Clean Air Act (CAA) to inform Congress of progress in reducing public health risks from urban air toxics. 

"This report gives everyone fighting for clean air a lot to be proud of because for more than 40 years we have been protecting Americans – preventing illness and improving our quality of life by cutting air pollution - all while the economy has more than tripled," said EPA Administrator Gina McCarthy. "But we know our work is not done yet. At the core of EPA's mission is the pursuit of environmental justice - striving for clean air, water and healthy land for every American; and we are committed to reducing remaining pollution, especially in low-income neighborhoods."

Using national emissions and air quality data, the Urban Air Toxics Report shows the substantial progress that has been made to reduce air toxics across the country since the Clean Air Act Amendments of 1990.

-   A 66 percent reduction in benzene;
-   A nearly 60 percent reduction in mercury from man-made sources like coal-fired power plants;
-  An 84 percent decrease of lead in outdoor air, which slows brain development in children;
-  The removal of an estimated 1.5 million tons per year of air toxics like arsenic, benzene, lead and nickel from stationary sources and another 1.5 million tons per year (about 50 percent) of air toxics from mobile sources. This is significant because air toxics (also referred to as hazardous air pollutants or HAPs) are known or suspected of causing cancer and can damage the immune, respiratory, neurological, reproductive and developmental systems;
- And, approximately 3 million tons per year of criteria pollutants, like particulate amtter and sulfur dioxide, have been reduced from cars and trucks as co-benefits of air toxics reductions.


Reducing toxics is a top priority for EPA, and even with this progress, we continue to improve our understanding of them, so we can effectively reduce remaining risks, particularly in overburdened communities. EPA's Plan EJ 2014, is making sure environmental justice is addressed in programs and policies across the agency. EPA is working closely with state, local and tribal agencies to promote area-wide and regional strategies to address air toxics and support a number of community-based programs that help communities understand, prioritize and reduce exposures to toxic pollutants in their local environment. For example, in Indianapolis, we are working with partners on the ground through an EPA grant for the "Building Lead Safe Communities" Project in the Martindale-Brightwood and Nearwest neighborhoods. We're addressing the risk of toxic lead exposure in children through outreach efforts and compiling block level soil lead data, identifying hotspots utilizing air sampling and developing synergistic local solutions.

Additionally, recent EPA actions will further address toxic pollution in communities. Since 2005, EPA has taken steps to address air emissions from stationary sources that include major reductions from boilers, power plants, and Portland cement facilities. For example, the 2011 Mercury and Air Toxics Standards will prevent about 90 percent of the mercury in coal burned in power plants from being emitted to the air. The 2007 Mobile Source Air Toxics rule is projected to reduce toxics emitted from highway vehicles and nonroad equipment, which are known or suspected to cause cancer or other serious health and environmental effects, by 330,000 tons in 2030, including 61,000 tons of benzene, and VOC emissions (precursors to ozone and PM2.5) by over one million tons. We expect reductions in air toxics from cars and trucks to grow to 80 percent by the year 2030 as we get newer, cleaner vehicles on the road. The proposed updates to emission standards for petroleum refineries would reduce emissions from the 150 petroleum refineries across the U.S., many of which are located near communities.  It would also reduce emissions of chemicals such as benzene, toluene and xylene by 5,600 tons per year.  These efforts, along with the implementation and adoption of new and existing national rules for stationary and mobile sources of pollution, will improve public health for all Americans by providing further reductions in air toxics.

Abraham Lincoln’s “Blind Memorandum”


(The following is a guest post by Michelle Krowl, a historian in the Library of Congress Manuscript Division.)

Could George B. McClellan have become the seventeenth President of the United States? It certainly appeared to be a possibility as Abraham Lincoln assessed the military and political landscape of the United States in the summer of 1864.

President Lincoln understood that his chances of reelection in November hinged on military success in a war now in its fourth year. By the summer of 1864, Gen. Ulysses S. Grant had settled in for a prolonged siege against the Confederates near Petersburg, Va., and Gen. William T. Shermanmade slow progress toward Atlanta. ConfederateGen. Jubal A. Early, meanwhile, had led his troops to the very gates of Washington, D.C. in July. The war effort seemed to have stalled for the Union, and the public blamed President Lincoln.

The political news for Lincoln was no brighter. Republican insider Thurlow Weed told Lincoln in mid-August 1864 that "his re-election was an impossibility." Republican party chairman Henry J. Raymond expressed much the same sentiment to Lincoln on Aug. 22, urging him to consider sending a commission to meet with Confederate President Jefferson Davis to offer peace terms "on the sole condition of acknowledging the supremacy of the Constitution," leaving the question of slavery to be resolved later.

"Everything is darkness and doubt and discouragement," wrote Lincoln's secretary, John G. Nicolay, in August 1864. "Our men see giants in the airy and unsubstantial shadows of the opposition, and are about to surrender without a fight."

Abraham Lincoln, text of "Blind Memorandum," August 23, 1864, Abraham Lincoln Papers, Manuscript Division, Library of Congress.

It was in this context that Abraham Lincoln wrote the following memorandum on Aug. 23, 1864:

This morning, as for some days past, it seems exceedingly probable that this Administration will not be re-elected. Then it will be my duty to so co-operate with the President elect, as to save the Union between the election and the inauguration; as he will have secured his election on such ground that he can not possibly save it afterwards.  – A. Lincoln

Lincoln folded the memorandum and pasted it closed, so that the text inside could not be read. He took it to a cabinet meeting and instructed his cabinet members to sign the outside of the memo, sight unseen, which they did. Historians now refer to this document variously as the "Blind Memo" or"Blind Memorandum" because the cabinet signed it "blind." In so doing the Lincoln administration pledged itself to accept the verdict of the people in November and to help save the Union should Lincoln not be re-elected.

As if on cue, Lincoln's fortunes began to change. As expected, the Democrats nominated George B. McClellan for president on August 30 but saddled him with a "Copperhead" peace Democrat, Representative George H. Pendleton, as a running mate. The Democratic platformdeclared the war a failure and urged that "immediate efforts be made for a cessation of hostilities," which even McClellan could not fully support. Then General Sherman scored a tremendous victory when Atlanta fell to the Union on Sept. 2.

The brighter military outlook, expert political maneuvering by Lincoln and his reinvigorated party (running in 1864 as theNational Union Party), and thenegatives associated with McClellan and the Democrats spelled victory at the polls for the Republicans. Safely re-elected, Lincoln brought the memorandum with him to the next cabinet meeting on November 11. He finally read its contents to the cabinet, reminding them it was written "when as yet we had no adversary, and seemed to have no friends."

On its 150th anniversary, the "blind memorandum" reminds us that historical outcomes we may take for granted in hindsight (like Lincoln's re-election in 1864) do not always appear so certain at the time.

How to Avoid Fumbling the Football in the Red Zone of Retirement

The 6 Documents You Need for Your Estate Plan Playbook

The start of football season may be months away, but the game's on the minds of many after the NFL draft. Minicamps are gearing up and team personnel are organizing in preparation for the 2014-15 season.

Football is a big deal in the United States – and so is the surge of retirees – 10,000 baby boomers every day for the next 18 years, says multi-certified planner Larry Roby. The last thing pre-retirees want to do at this stage of their lives is to fumble while in the red zone of their retirement date, he says.

"Only 23 percent of pre-retirees have calculated how much they'll need to save for retirement, according to New Retirement Landscape; while three-quarters say they're confident in the red zone of retirement, an equal amount of people haven't even done the math yet!" says Roby, founder and president of Senior Financial Advisors, (www.sfabridge.com), a wealth-management firm that holds ethics and education as top priorities.

"Confidence in your retirement portfolio is good – if it's justified. Otherwise, it can lull people into a false sense of security and lack of preparedness."

Having a diverse portfolio and understanding your options for life insurance, Social Security and 401(k) or other retirement accounts are staples for retirement planning. But there are also six crucial documents that are often either not in an individual's playbook or are overlooked.

Here are the six documents you need for a solid red zone estate plan:

•  Joint Ownership -- Enables you to own property jointly with another person and upon the death of the joint tenant, the surviving joint tenant automatically becomes the owner of the property.

•  Last Will and Testament – A legal document which expresses the wishes of a person concerning the disposition of their property after death and names the person who will manage the estate.

•  Durable Power of Attorney – Grants authority to another individual to act on behalf of the person who executes the instrument and are commonly used for legal and financial purposes.

•  Durable Health Care Power of Attorney- Grants authority to another individual to make health care decisions on your behalf should you be unable to make such decisions.

•  Advance Care Directive – A set of written instructions in which a person specifies what actions should be taken for their health, if they are no longer able to make decisions due to illness or incapacity.

•  Living Trust – Created during your lifetime.  Assets are transferred to the trust while you are alive.  Provides written instructions for the disbursement of the trust assets upon your death.

"These documents can play a vital role in the major plays during the fourth quarter of your life," Roby says. "Understanding how they work now can make the difference between a last-minute victory or loss."

A Promising Pilot to Help Student Borrowers

Investing in postsecondary education is among the smartest choices Americans can make. College completion opens doors and expands economic opportunity, leading to lower rates of unemployment and higher earnings over the course of a career. But tuition rates have risen significantly in recent decades, and obtaining a college degree increasingly depends on students' ability to take out loans and manage repayment after leaving school. While most borrowers are able to repay their student loans, many struggle, and some fall behind.

That's why last month the President and his Administration announced a series of executive actions to help reduce the burden faced by student loan borrowers and make postsecondary education more affordable and accessible to American families. A centerpiece of this action plan is to improve the effectiveness of communications to borrowers about flexible repayment options the U.S. Department of Education offers to help ensure they stay on track with their payments. This includes income-driven repayment plans – Income-Based Repayment, Pay As You Earn, and Income-Contingent Repayment – that link monthly payments to borrower incomes.

We know borrowers are busy and that decisions about student loan plans can be complex and challenging. That's why the Office of Federal Student Aid at the Department of Education has teamed up with the White House Social and Behavioral Sciences Team, a group of experts who focus on effective, innovative strategies for helping government programs and communications better serve citizens.

In November 2013, Federal Student Aid, in collaboration with the White House Social and Behavioral Sciences Team, launched an e-mail campaign to increase awareness of Income-Driven Repayment and help borrowers make more informed decisions about loan repayment options given their circumstances. The campaign sent emails to borrowers who had fallen behind on their payments, had higher-than-average debts, had grace periods coming to an end, had deferred or entered forbearance because of financial hardship or unemployment, or some combination of the above. In total, the campaign sent emails to over three million borrowers last year and 221,000 submitted applications.

The team embedded a rigorous, randomized-control pilot into the broader campaign, which measured the impact of e-mails designed based on insights from the behavioral sciences on action among borrowers in delinquency for 90-180 days. These e-mails indicated income-driven repayment eligibility criteria, the benefits associated with taking action and the costs associated with inaction, and the relevant web-links and servicer contact information. Behavioral science research demonstrates that timely, clear and low-cost informational messages of this kind can help citizens better understand their options, make more informed decisions, and follow through on their intentions.

Results of the pilot are promising. Sending e-mails to borrowers in delinquency for 90-180 days resulted in a statistically significant, four-fold increase in completed income-driven repayment applications. This effect translates into roughly 6,000 additional completed applications in just the first month after sending among the 841,442 borrowers in the pilot.

We are working together to use insights from this trial to inform future communications and develop even more effective ways of reaching borrowers to help them stay on track.

Face of Defense: Troops Deploy to South Korea for Exercise

By Walter Ham

20th CBRNE Command

YONGSAN GARRISON, South Korea, Aug. 21, 2014 - The U.S. Army's only command that combats chemical, biological, radiological, nuclear and explosive threats is participating in this year's Ulchi Freedom Guardian exercise held in South Korea Aug. 18-29.

The Aberdeen Proving Ground, Maryland,-based 20th CBRNE Command (Chemical, Biological, Radiological, Nuclear, Explosives) is training with other U.S. and South Korean military forces during the annual exercise.

Defensive in nature, the command post exercise is designed to keep U.S. and South Korean forces ready to maintain security and stability on the Korean Peninsula and in the region. The exercise is named after Ulchi Mundeok, a 7th century Korean military leader who repelled an invasion by China's Sui Dynasty. It is the second of two command post exercises held every year in South Korea.

This year, Ulchi Freedom Guardian involves 3,000 personnel from military bases in the U.S. and across the Pacific region. U.S. and South Korean forces are being joined by United Nations Command forces from Australia, Canada, Colombia, Denmark, France, Italy, Netherlands, New Zealand, Norway and the United Kingdom.

Soldiers and civilians with the 20th CBRNE Command are trained to counter weapons of mass destruction, eliminate CBRN and explosive ordnance threats, and defeat improvised explosive devices.

With specialized units on 19 installations in 16 states, the 20th CBRNE Command trains with joint, interagency and allied partners around the globe.

According to 20th CBRNE Command Chief of Staff Army Col. Rich Schueneman, the deployment of nearly 100 20th CBRNE soldiers to South Korea to participate in Ulchi Freedom Guardian demonstrates the command's operational flexibility.

"The 20th CBRNE Command is ready, reliable and globally responsive," said Schueneman, a Bristol, Indiana, native who previously served with the 1-72nd Tank Battalion in South Korea. "This is one of our nation's oldest and strongest alliances and we welcome the opportunity to train with our South Korean allies."

Video: U.S. Attempted Hostage Rescue in Syria


℠2014 - Pentagon Press Secretary RADM John Kirby says a U.S. attempt to rescue American hostages in Syria was unsuccessful because the hostages were not at the targeted location.

New Report: Sentencing Guidelines



Law Library Stacks

Back to Legal Topics

Sentencing guidelines in the common law countries of Australia, England and Wales, IndiaSouth Africa, and Uganda vary significantly.  England and Wales have a Sentencing Council that develops offense-specific guidelines that the courts must follow, while Uganda's Supreme Court has developed guidelines that are advisory only.  In India and Australia, no formal guidelines exist and judges retain wide discretion in sentencing, but both countries have mechanisms in place to provide general guidance—in Australia through state legislation and in India through a series of court decisions that identify relevant sentencing factors.

Full Report (PDF, 370KB)

Australia

In Australia, all jurisdictions have sentencing laws that provide general guidance on principles and factors to be taken into account in sentencing. However, judges retain significant discretion and utilize an individualized approach to justice. There has been considerable political debate about the need for and effectiveness of mandatory minimum sentencing laws, which have been enacted in a number of jurisdictions, often as a result of public concerns regarding sentencing for particular offenses or in individual cases.

During the last ten years, several states have established sentencing advisory councils in an effort to increase the amount of information and analysis available regarding sentencing matters. One of the broader goals of this approach is to improve public confidence in the justice system.

Read More

England and Wales

The English justice system considers that sentences imposed on offenders should reflect the crime committed and be proportionate to the seriousness of the offense. It has a Sentencing Council that is responsible for producing, issuing, and reviewing guidance to the courts on what factors should be considered when sentencing offenders and the range of sentences that should be awarded, among other things. The guidance should be followed, unless it is not in the interests of justice to do so. The aim of the guidance is to ensure consistency in sentencing across the country.

India

In India neither the legislature nor the judiciary has issued structured sentencing guidelines. Several governmental committees have pointed to the need to adopt such guidelines in order to minimize uncertainty in awarding sentences. The higher courts, recognizing the absence of such guidelines, have provided judicial guidance in the form of principles and factors that courts must take into account while exercising discretion in sentencing.

Read More

South Africa

In South Africa, sentencing is considered the primary prerogative of trial courts and they enjoy wide discretion to determine the type and severity of a sentence on a case-by-case basis. In doing so, they follow judge-made, broad sentencing principles known as the "triad of Zinn," which require that, when making sentencing determinations, judges consider three things: the gravity of the offense, the circumstances of the offender, and public interest.

Read More

Uganda

The Chief Justice of the Supreme Court of Uganda recently issued advisory Sentencing Guidelines aimed at bringing uniformity, consistency, and transparency to the sentencing process in the country by establishing sentencing ranges and other sentencing guides.  Although the Sentencing Guidelines cover only a limited number of offenses at present, they do provide general sentencing principles and various sentencing factors that are applicable to offenses not specifically covered.

Among the notable aspects of the Sentencing Guidelines is the emphasis on victim and community engagement in the sentencing process, restorative justice, and the promotion of noncustodial sentences.

Shock waves from battlefield explosions are invisible threats for U.S. soldiers and their top-of-the-line combat helmets, but with new studies in synthetic human physiology, researchers are learning how to lessen blast wave effects on the brain.


Exactly how, and to what degree, these waves cause brain damage is what the U.S. Army Research Laboratory scientists and engineers and a group of university partners are trying to answer as part of a multi-year, multi-disciplinary research project.
ARL researchers are taking multiple approaches at studying the impact of shock waves inside, on and outside of the skull, and they expect to discover what's needed to make Army helmets go beyond protecting the head to protecting the brain. (Photo from the Army Research Lab/Released)

In a related research project, Army researchers are investigating new material development for helmet padding systems and from this research, they expect greater insight and innovation in addressing what is likely to be the next big development in head protection: strategies for mitigating the effects of blast.
They're creating synthetic cranial bones that look and behave like the skulls of 20- and 30- year old soldiers that will be tested in laboratory experiments that mimic combat-like blast events in hopes of improving military helmet pads, shells, and other protective equipment.
Dr. Thomas Plaisted, materials engineer in the Materials and Manufacturing Science Division at the ARL, said even though synthetic bones are commercially available they're used primarily by doctors to practice surgical procedures. But, their design prevents them from "behaving like real human bones when subjected to blast tests."
"The mechanical properties of the human skull change with age and depend on the health of the individual. Donor skulls that may be available for testing would typically come from older people, and the properties of those skulls can be highly variable and may not have the same response as the average skull of the Army soldier population," said Plaisted.
He said this is among the variables that "add uncertainty when trying to evaluate head protection devices, like helmets."
"So we are developing our own synthetic bone capturing material and architecture response, specific to the human skull."
The skull simulant ARL researchers are developing is made of synthetic materials with the goal of creating a uniform response that is representative of the soldier population to use in tests to understand how to best protect the head during exposure to blast waves and blunt impact.
"The cranial bones have a highly-graded structure, from a tough outer layer, a spongy inner section, to a more brittle inner layer, which together are responsible for how it responds under impact conditions, he said.

Slice-by-slice images taken from a CT scan help researchers get the geometry and structure of the skull right. ARL composite materials combined with these images rely on 3D printing technology to produce models of bone-like surrogates that ARL researchers will use to test new helmet padding materials in simulated blast and impact conditions. The goal is to determine how the pads and helmet shell materials protect the head from injury, Plaisted said.
"We are developing new helmet padding materials to improve the impact protection afforded by the Army's helmets. The helmet can withstand impact at a certain velocity while protecting the head from accelerations that would lead to injury. In the extreme case, excessive acceleration may lead to skull fracture," he said.
"We are using computer modeling of head and helmet impacts to understand how tailoring the padding properties can reduce acceleration at various impact locations around the helmet. Then, those properties are engineered into materials and tested in the laboratory to validate what we are seeing in the computer models. The research is giving insight on optimal material structures and material combinations that achieve increased energy absorption while still being comfortable to wear."
Earlier this year, ARL evaluated the base material of the synthetic bones by hitting it a high rate, and comparing the fracture properties to human bones tested by the same technique. They've determined it to be a "close match" to human bones, he said.
"Our next step is in determining the limits of resolution we can achieve with the 3D printing, and how fine the resolution needs to be to capture the properties we are looking for."
He said he expects to start printing synthetic skulls with 3D technology by the fall.
"Part of ARL's mission is to take varying levels of risk in finding state of the art science and developing the technologies that could potentially provide the soldier with more protection, more capability, or both. What is equally important is that ARL strategically reduce the risk of these new technologies so that RDECs, such as Natick Soldier RDEC, can begin to think about how they would integrate into a larger soldier "system." Many of ARL's material, processing, and conceptual technologies were transitioned and demonstrated in NSRDEC's "HEaDS UP" program," said Dr. Shawn Walsh, who leads ARL's Agile Manufacturing Technology Team .
"[Dr. Plaisted's] efforts are unique in that he is bringing fundamental material science and modeling to the dual problem of accurately representing biological systems (for example the skull) and coupling this biological model to a materials model to provide better insight on how impulses are transmitted during an impact to the helmet and head. Such insight will lead to new and quantifiably proven methods for reducing the adverse effects of violently applied forces to the head and helmet system," Walsh said.

Research Paves Way for Development of Cyborg Moth ‘Biobots’

North Carolina State University researchers have developed methods for electronically manipulating the flight muscles of moths and for monitoring the electrical signals moths use to control those muscles. The work opens the door to the development of remotely-controlled moths, or "biobots," for use in emergency response.

"In the big picture, we want to know whether we can control the movement of moths for use in applications such as search and rescue operations," says Dr. Alper Bozkurt, an assistant professor of electrical and computer engineering at NC State and co-author of a paper on the work. "The idea would be to attach sensors to moths in order to create a flexible, aerial sensor network that can identify survivors or public health hazards in the wake of a disaster."
The paper presents a technique Bozkurt developed for attaching electrodes to a moth during its pupal stage, when the caterpillar is in a cocoon undergoing metamorphosis into its winged adult stage. This aspect of the work was done in conjunction with Dr. Amit Lal of Cornell University.
But the new findings in the paper involve methods developed by Bozkurt's research team for improving our understanding of precisely how a moth coordinates its muscles during flight.
By attaching electrodes to the muscle groups responsible for a moth's flight, Bozkurt's team is able to monitor electromyographic signals – the electric signals the moth uses during flight to tell those muscles what to do.
The moth is connected to a wireless platform that collects the electromyographic data as the moth moves its wings. To give the moth freedom to turn left and right, the entire platform levitates, suspended in mid-air by electromagnets. A short video describing the work is below.
"By watching how the moth uses its wings to steer while in flight, and matching those movements with their corresponding electromyographic signals, we're getting a much better understanding of how moths maneuver through the air," Bozkurt says.
"We're optimistic that this information will help us develop technologies to remotely control the movements of moths in flight," Bozkurt says. "That's essential to the overarching goal of creating biobots that can be part of a cyberphysical sensor network."
But Bozkurt stresses that there's a lot of work yet to be done to make moth biobots a viable tool.
"We now have a platform for collecting data about flight coordination," Bozkurt says. "Next steps include developing an automated system to explore and fine-tune parameters for controlling moth flight, further miniaturizing the technology, and testing the technology in free-flying moths."
The paper, "Early Metamorphic Insertion Technology for Insect Flight Behavior Monitoring," is published online in the Journal of Visualized Experiments(JoVE). JoVE publications have two parts, a written component and a video describing the work.
The paper was co-authored by Alexander Verderber and Michael McKnight, Ph.D. students in Bozkurt's lab at NC State. The research was supported by the National Science Foundation, under grant CNS-1239243. The researchers also used transmitters and receivers developed by Triangle Biosystems International and thank them for their contribution to the work.
