UNITED STATES CHAMBER OF COMMERCE
As Congress gears up to debate reauthorization of surface transportation programs, this report is intended to call attention to a significant emerging threat to addressing the aforementioned transportation challenges: the Environmental Protection Agency’s (EPA) forthcoming ozone national ambient air quality standards (NAAQS). This report analyzes the impact of these regulations on transportation projects, with a focus on the Washington, D.C. metropolitan area.

U.S. EPA: Working to Safeguard our Drinking Water

Nick Dugan is an environmental engineer working in EPA’s Cincinnati laboratory. He is currently focused on bench-scale trials evaluating the impact of common drinking water treatment oxidants on intact, toxin-producing cyanobacterial cells over a range of water quality conditions.

Northeast & Mid-Atlantic: Economic Impacts of a Greenhouse Gas Initiative

Figure ES-1 Actual CO2 Emissions in the RGGI States, Relative to the Emissions Caps in Different Periods

ANALYSIS GROUP
This Report analyzes the economic impacts of RGGI’s most recent three years, covering the years 2012 through 2014. This analysis follows on our prior November 2011 Report (hereafter “AG 2011 Report”) that assessed the economic impacts of RGGI’s first three years (2009-2011). Since the time of our last economic review, the electric industry has experienced changes in power plant economics, emission-control requirements, and wholesale market structures in the RGGI region. In addition, the RGGI states completed a comprehensive program review during 2012, and modified elements of the program including, most importantly, adopting a significantly lower overall cap on CO2 emissions in the RGGI region.

Climate Change in the United States: Benefits of Global Action

GHG Mitigation: Estimated Benefits to the U.S. in 2100

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY
Actions can be taken now to reduce GHG emissions and avoid many of the adverse impacts of climate change. Quantifying the benefits of reducing GHG emissions (i.e., how GHG mitigation reduces or avoids impacts) requires comparing projections of climate change impacts and damages in a future with policy actions and a future without policy actions. Looking across a large number of sectors, this report communicates estimates of these benefits to the U.S. associated with global action on climate change.

U.S. EPA: New England is Using Green Infrastructure to “Soak Up The Rain”

U.S. EPA: New England is Using Green Infrastructure to “Soak Up The Rain”

Polluted stormwater runoff is one of the greatest threats to clean water in the nation. EPA-New England launched its “Soak up the Rain” outreach program to raise public awareness about these threats, and help communities understand how green infrastructure (GI) strategies can help mitigate runoff damage. GI uses natural processes (vegetation and soil infiltration) to absorb and treat runoff at its source while offering additional benefits that can include flood mitigation, economic protection, habitat preservation and quality of life improvements. This video shows citizens from several communities using GI to mitigate their stormwater problems; people including school principals, municipal DPW officials, residential property owners and landscape professionals. The video also illustrates how Soak up the Rain actively promotes community efforts to reduce runoff and showcases specific GI projects.

Drinking Water & Fracking: Risk Assessment

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY
From our assessment, we conclude there are above and below ground mechanisms by which hydraulic fracturing activities have the potential to impact drinking water resources. These mechanisms include water withdrawals in times of, or in areas with, low water availability; spills of hydraulic fracturing fluids and produced water; fracturing directly into underground drinking water resources; below ground migration of liquids and gases; and inadequate treatment and discharge of wastewater.

Lawrence, MA: Old Rails to Green Trails

With the help of EPA’s $200,000 Brownfields Area-wide planning grant, this video shows Lawrence Mayor Dan Rivera and Congresswoman Niki Tsongas explain the catalytic impact of EPA funding to jumpstart improvements and community outcomes for citizens in underserved communities, such as Lawrence, MA. By planning for, and envisioning, new walking paths to replace a blighted old railway that cuts through the City, residents will someday be able to link to adjacent recreational trails. This video shows the “before” of a key community project that will change the future face of Lawrence and make a real difference to its citizens.

EPA’s Clean Power Plan and Reliability

Figure 1 Application of BSER for 2030 CO2 Emissions Rate Standards by State

THE BRATTLE GROUP
The United States (“U.S.”) power system is undergoing a fundamental transformation, largely driven by advances in technology and low natural gas prices. This transformation is putting significant pressure on existing coal-fired and even nuclear generation, increasingly leads to renewable energy resources being cost-competitive with fossil-fired generation, and results in myriad choices for consumers that promise to permanently alter the role of demand in the power system. As a consequence, the fuel mix and associated emissions of the U.S. power system are changing rapidly, as are the actions taken by system operators to manage the quickly evolving electric system.

EPA: Technology Promotes Environmental Protection

EPA’s National Enforcement Investigations Center is an environmental forensic center. NEIC scientists work with a variety of technologies to monitor, collect data and analyze pollutants in the environment to better understand the threat to human health and ecosystems. Advanced technologies provide tools for scientists to measure, sometimes in near real-time, pollutants emitted from both large and small sources that can adversely affect entire communities.
