Commentary: U.S. House of Representatives Passes Bill To Weaken EPA Clean Air Rules
October 19, 2011 01:55 PM - Dominick DalSanto, Baghouse.com

Two bills are currently working they way through the U.S. Congress in an attempt to stay activation of new air pollution regulations propagated by the U.S. Environmental Protection Agency, namely additions to the NESHAP, Cement MACT, and Boiler MACT standards scheduled to take effect in the next few months. The new regulations will require most facilities to install updated dust collection systems to meet more stringent emissions levels. The pair of bills, the Cement Sector Regulatory Relief Act of 2011 and the EPA Regulatory Relief Act of 2011, are part of a larger effort by conservatives to curtail the so-called "aggressive" agenda of the EPA. Several different EPA rule sets are covered by the bill, but the main three are the National Emission Standards for Hazardous Air Pollutants (NESHAPs), Boiler MACTs (Maximum Available Control Technology), and Cement MACTs which covers emissions from the manufacture of cement. The standards are either new, or updates to existing EPA regulations. The EPA NESHAPs cover the six basic air pollutants the EPA regulates, carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter e.g. dusts smaller than 2.5 microns (PM2.5), lead, and ozone. These rules were recently revised to include stricter limits.

Can piranhas eat a human being alive?
October 12, 2011 01:53 PM - the Deadly 60 Team, BBC Earth

Seeking out the truth behind the myth, Steve and his Deadly team take to the water to find out exactly why the piranha has developed such a fearsome reputation. Legend has it that piranhas gather in predatory shoals and can strip human beings to the bone and eat them alive. The yellow-bellied piranha has a horrific appearance, with a mouth packed full of 4mm long canines, which, like sharks, are constantly replaced when lost or worn down. They can also detect a drop of blood in 200 litres of water and shoals can clean off meat from a carcass with alarming effectiveness. When Steve travelled to the Amazon river he went in search of this notorious killer fish. Getting in the water to lure them in with a piece of steak had frightening results.

Global CO2 Emissions Reach All-Time High, Rising More Than 5% in 2010 to Close Out Past 20 Years
September 28, 2011 04:14 PM - Andrew Burger

Global carbon dioxide (CO2) emissions reached an all-time high in 2010, rising 45% in the past 20 years. Rising rapidly between 1990 and 2010, global atmospheric CO2 levels totaled 33 billion metric tons last year, according to a report published by the European Commission’s Joint Research Center and PBL Netherlands Environmental Assessment Agency. Global CO2 emissions fell 1% in 2009, during the Great Recession, but rose at an unprecedented 5% rate in 2010. That was similar to the drop and greater emissions growth in 1975 and 1976, when the global economy suffered through the first oil crisis, a subsequent stock market crash and began a recovery in 1976, the report authors note.

How to run with wolves
September 21, 2011 04:59 PM - Deadly 60 team, BBC Earth

Traveling to the frozen north, Steve and his Deadly 60 team met an animal whose ability to survive in sub-zero temperatures, has made it one of many Norwegian success stories. But how close could they really get to this hardened predator? Well, sorry, you can't. No matter what the Twilight movie says! Wild wolves are extremely hard to get close to, and it's not sensible to try! They are top predators, the largest of the wild dog family living in complex social groups, in remote inhospitable places. They are incredibly hard to see and track in the wild, travelling over huge distances and running at speeds of over 30mph in pursuit of prey. They are ferocious hunters tackling prey many times their own size like elk, bison and musk ox. Wild wolves are not to be messed with.
