Almennilegt – sektað vegn rykmyndunar við byggingarframkvæmdir / Good – builder fined for violating dust control measures > $100k

Frétt sem segir frá verktaka í Arizona sem var sektaður um yfir 100 þúsund dollara vegna þess að hann gætti ekki að sér varðandi rykmengun við framkvæmdirnar !

Meðal þess sem verktakar eiga að sinna, en þessi gerði ekki, er:

  • setja upp hreinsitæki fyrir farartæki/vinnuvélar;
  • hreinsa strax öll óhreinindi sem berast meira en 50 fet frá vinnusvæðinu;
  • hafa vatnsúðara í gangi þegar jarðefni er flutt;

Hvernig væri að koma svona reglum í gagnið hérlendis !

Arizona Builder Fined More than $100K for Violating Dust Control Measures

EPA has fined Summit Builders Construction Co., based in Maricopa County, Arizona, $105,610 for allegedly failing to comply with Clean Air Act regulations. In addition to the monetary fine, Summit also is required to take steps to minimize the generation of dust at its construction sites.

“Air pollution from particulate matter directly impacts the health of the community. It’s an especially serious issue in Maricopa County, where air quality does not meet the federal standard,” said Jared Blumenfeld, EPA’s regional administrator for the Pacific Southwest region. “EPA will not tolerate companies who fail to comply with dust control regulations. We are working closely with local air quality agencies to enforce rules to protect the community from airborne dust.”

U.S. Attorney Dennis K. Burke for the District of Arizona added, "Air quality is a concern for many who live in and travel through Maricopa County. The resolution of this case provides for positive measures which will help improve air quality in the future."

In 2006 and 2007, the Maricopa County Air Quality Department (MCAD) inspected five commercial construction projects in Maricopa County and uncovered eight violations for failing to perform various measures required to reduce particulate matter emissions. These included failure to install a trackout control device to remove particulate matter from vehicles; failure to immediately clean up dirt that is tracked more than 50 feet beyond the site; failure to operate a water application system during earthmoving operations; and failure to comply with the dust control plan.

In addition to the penalty, Summit is required to train employees in basic dust control, document that training, and employ qualified dust controls at larger work sites for two years.

Maricopa County exceeds the national health standard for particulate matter, PM-10 (one-seventh the width of a human hair), and has been classified by the EPA as a serious non-attainment area. In May 2010, EPA denied Arizona’s claim that dust storms caused the high pollution readings in Phoenix. Because of this, Arizona must submit an adequate plan to EPA on how the state plans to come into attainment for PM-10. Failure to do so will result in a freeze to the state’s federal transportation funds.

EPA notes that particulate matter affects the respiratory system. Particle pollution is a complex mixture of extremely small particles and liquid droplets in the air. When breathed in, these particles can reach the deepest regions of the lungs, and is linked to a variety of significant health problems, ranging from aggravated asthma to premature death in people with heart and lung disease. The elderly, children, and people with chronic lung disease, influenza, or asthma are especially sensitive to high levels of particulate matter, the agency said.

Snæfellsjökull að hverfa ? / Snæfellsjökull dissapearing ?

Í nýlegu viðtali á RÚV (http://www.ruv.is/frett/snaefellsjokull-ad-hverfa) talaði Helgi Björnsson um hversu hratt Snæfellsjökull hefur minnkað og hvernig árið í ár sé honum ekki hliðhollt.

In a recent interview (http://www.ruv.is/frett/snaefellsjokull-ad-hverfa) Helgi Björnsson discussed how Snæfellsjökull is retreating rapidly and how this year will not be good for the “health” of the glacier.

Erfitt að sjá mun á þessum stutta tíma og í þessari upplausn.

Difficult to see any difference over such a short time span and low resolution.

Heat wave in early July 2010 / Hitabylgjan í byrjun júlí 2010

Víða í BNA og Evrópu var óvenju heitt í byrjun júlí. Kortið hér að neðan sýnir hitastigs-frávik fyrir vikuna 4 – 11 júlí 2010, samanborið við sömu dagsetningar árin 2000 – 2008.

Nýleg rannsókn vísindamanna við Stanford háskóla bendir til þess að í BNA verði hitabylgjur algengar og langvarandi innan 30 ára (http://www.eurekalert.org/pub_releases/2010-07/su-hwc070810.php).

In parts of USA and Europe early July was unusually hot. The map below shows the temperature anomaly for the week of 4 – 11 July 2010, compared to the same dates in 2000 – 20008.

Recent studies by scientists at Stanford suggest that long heat waves will be common within the next 30 years (http://www.eurekalert.org/pub_releases/2010-07/su-hwc070810.php).

Flott skýjamunstur / Nice pattern in the clouds

Flott mynstur sést í skýjunum yfir austfjörðum á þessari gervitunglamynd frá því kl. 13:31 þann 16. júlí 2010. Væntanlega einhversskonar standandi bylgja (e. standing wave).

Satellite image from 13:31 on 16 July 2010 shows nice pattern in the clouds over the eastern fjords of Iceland. Likely some kind of standing wave pattern.

Myndir frá Everest sýna að mikið af ís hefur tapast / Everest photos 'confirm ice loss'

Mikið af ís hefur tapast á Everest, en það sýna myndir teknar nýlega og árið 1921 - sjá hlekk og myndir að neðan.

Everest photos 'confirm ice loss': "Photos taken by a mountaineer on Everest from the same spot where similar pictures were taken in 1921 reveal an 'alarming' ice loss."

The 1921 photo (left) and the photo taken from the same position in 2010
Experts say comparing the 1921 photo (left) with the photo of 2010 proves that the ice mass is disappearing

Ísjakar brotna hratt af íshellunni við NA-Grænland / Icebergs brake off quickly, NE-Greenland

Ísjakar brotna hratt af íshellunni við norðaustur Grænland.
Icebergs brake off quickly off the iceshelf in NE-Greenland.

Myndirnar tvær fyrir neðan eru frá 13 og 14. júlí 2010. Fyrri daginn er íshellan nánast alveg heil, en daginn eftir má sjá að stór ísjaki hefur brotnað af.
The two images below are from 13 and 14 of July 2010. The first day shows a relatively whole iceshelf, while on the latter day a large chunk has broken off.

Á annað hundrað hafa látið lífið og mörg þúsund orðið heimilislausir vegna ofsaveðurs og flóða í austur Asíu síðasta sólarhring. Í Kína þurfti að sprengja stíflu til að bjarga hundrað þúsund manna borg.

Í morgun þótti hætta á að flóðvarnargarðar myndu bresta með þeim afleiðingum að borgin Tongcheng þurrkaðist út en þar búa hundrað þúsund manns.
