Slow-moving 'earthquake' under Olympic Peninsula monitored by University of Washington, will help understand devastating quakes
August 18, 2010 08:04 AM - Roger Greenway, ENN

New research published by University of Washington seismologists reports the results of monitoring they have been recording of a slow-moving and unfelt seismic event under the Olympic Peninsula. It promises to be the best-documented such event in the eight years since the regularly occurring phenomena were first discovered. "It appears to be right on time," Steve Malone, a UW Earth and space sciences professor, said of the most recent of what are termed episodic tremor-and-slip, or slow-slip, events. "The first signals were mostly fairly weak, but they were easily detected." The first ground motion associated with the event was recorded very early Sunday morning in an area north of Olympia and west of Tacoma. By Monday afternoon the signals were substantially stronger. If the event behaves like past occurrences, the source of the rumbling will move north through the Olympic Peninsula during the next week before crossing the Strait of Juan de Fuca to Canada's Vancouver Island

Oregon Dead Zone
August 17, 2010 10:26 AM - Andy Soos, ENN

Dead zones are hypoxic (low-oxygen) areas in the world's oceans, the observed incidences of which have been increasing since oceanographers began noting them in the 1970s. These occur near inhabited coastlines, where aquatic life is most concentrated. Every summer for the past nine years, water with lethally low concentrations of oxygen has appeared off the Oregon coast. The cause is not clear and it does not fit the pattern of several other dead zones associated with man made run off issues. Some other causes have been recently implicated in a research study by Oregon State University.

Social Media, Technology, and Change Conference, New York City November 1st.
August 16, 2010 03:51 PM - Roger Greenway, ENN, Justmeans

ENN is proud to be a media sponsor of this important event hosted by our Affiliate, Justmeans. The rapid adoption of social media and the shift within corporations to measure and manage social and environmental impact is fundamentally changing the way companies engage with their stakeholders. Companies will need to work much more closely with stakeholders in order to navigate these two trends. Despite the complexities of this new landscape, a wide variety of best practices are emerging to aid organizations. A select group of corporate executives, social entrepreneurs, and digital gurus will meet to discuss emerging best practices in using social media to create positive social change at the 2010 Social Media, Technology, and Change conference, to be held on November 1st, in New York City. Topics to be discussed include:

Icebergs
August 16, 2010 10:36 AM - Andy Soos, ENN

An iceberg is a large piece of ice formed from freshwater that has broken off from a glacier or ice shelf and is floating in open water. It may subsequently become frozen into pack ice. Alternatively, it may come to rest on the seabed in shallower water, causing ice gouging in the land underneath or becoming an ice island. Because the density of pure ice is less than sea water an iceberg will float in sea water with about one-ninth of the volume of an iceberg above water. The shape of the underwater portion can be difficult to judge by looking at the portion above the surface. This has led to the expression "tip of the iceberg", for a problem or difficulty that is only a small manifestation of a larger problem.

The New Breeds of Cars
August 13, 2010 02:31 PM - Andy Soos, ENN

Decades ago the only type of car was the internal combustion (gasoline)type. Other varieties have arrived such as Hybrid and electric. With the new choices are other decisions such as which one reduces most the carbon footprint (or is the most green)and which one is the most cost effective. No more is "the miles per gallon" a standard that can be applied across the board as a specification.

EPA Proposes Permitting Rules for Greenhouse Gas Emissions — Texas Dissents
August 12, 2010 04:53 PM - Roger Greenway, ENN

Following the Greenhouse Gas Tailoring Rule, the US EPA issued a proposed two new rules to address the permitting issues which the tailoring rule created. The GHG Tailoring Rule, specifies that beginning in 2011, facilities that increase GHG emissions substantially will require an air permit. The EPA proposed two rules to ensure that businesses planning to build new, large facilities or make major expansions to existing ones will be able to obtain Clean Air Act permits that address their greenhouse gas (GHG) emissions. The Tailoring Rule covers large industrial facilities like power plants and oil refineries that are responsible for 70 percent of the GHGs from stationary sources. The new EPA proposals are a critical component for implementing the Tailoring Rule and would ensure that GHG emissions from these large facilities are minimized. The Clean Air Act requires states to develop EPA-approved implementation plans that include requirements for issuing air permits. When federal permitting requirements change, as they did after EPA finalized the GHG Tailoring Rule, states likely need to modify these plans.

How to Make the Most of Solar Power
August 12, 2010 03:31 PM - Andy Soos, ENN

A solar panel (photovoltaic module or photovoltaic panel) is a packaged interconnected assembly of solar cells, also known as photovoltaic cells. The solar panel is used as a component in a larger photovoltaic system to offer electricity for commercial and residential applications. There are many methods available to try to increase their output. There is now a new entrant to the realm of solar panel accessories that is said to increase panel performance while decreasing costs. Joining solar trackers and microinverters is a new polymer film called FUSION by Genie Lens Technologies.

Cleanup of Superfund Site Completed in Morris County, New Jersey
August 12, 2010 12:47 PM - David A Gabel, ENN

The US Environmental Protection Agency (EPA) has successfully completed the cleanup of a superfund site in Long Hill Township and Harding Township, Morris County, NJ. The site, at the edge of a National Wildlife Refuge, had formerly served as an asbestos dump. It has now been removed from the National Priorities List of hazardous waste sites.

EPA Sets Limits on Mercury and Other Air Emissions from Cement Kilns
August 11, 2010 04:44 PM - Roger Greenway, ENN

Cement plants emit mercury from the kilns used in the cement manufacturing process. Cement kilns operate at high temperatures, and are, in fact used to destroy many types of toxic substances. The rule, proposed on August 9, 2010 also applies to total hydrocarbons (THC), and particulate matter (PM) from new and existing kilns located at major and area sources, and for hydrochloric acid (HCl) from new and existing kilns located at major sources. The standards for new kilns apply to facilities that commence construction, modification, or reconstruction after May 6, 2009 The U.S. Environmental Protection Agency (EPA) issued final rules to cut emissions of mercury, particle pollution and other harmful pollutants from Portland cement manufacturing, the third-largest source of mercury air emissions in the United States. EPA calculates that the rules will yield $7 to $19 in public health benefits for every dollar in costs.

The Fish May Now Return
August 11, 2010 02:36 PM - Andy Soos, ENN

The Gulf of Mexico has been a problem for fishing and other marine life even since the BP oil spill earlier this year. Things are looking up finally. The National Oceanic and Atmospheric Administration (NOAA) has just reopened 5,144 square miles of Gulf waters to commercial and recreational finfish fishing. Since July 3, NOAA data have shown no oil in the newly reopened area, and United States Coast Guard observers flying over the area in the last 30 days have also not observed any visible oil. Even more importantly, fish caught in the area and tested by NOAA experts have shown no signs of contamination.
