This is one article out of thousands around the country. Green Planets Clean boost would solve all these issues in minutes if people knew about them.

Remember page 10 of this test data shows an 80 percent decrease in black soot from diesel vehicles after application.

AIR POLLUTION PINNED ON CONSTRUCTION REPORT: DIESEL FUMES JEOPARDIZE SCV RESIDENTS.

With the valley growing quickly, residential and commercial construction is a constant and black plumes of smoke over grading sites are common.

The kinds of diesel engines employed at construction sites are among the most polluting machinery in use these days, now that the trucking industry has cleaned shop.

``We have the tools to combat this situation,'' said report author Don Anair of the Union of Concerned Scientists The Union of Concerned Scientists (UCS) is a nonprofit advocacy group based in Cambridge, Massachusetts, United States. The UCS membership includes many private citizens in addition to professional scientists. . ``There's existing technology today that's currently available and can be used on (diesel) equipment.''

The Union of Concerned Scientists put Santa Clarita in the top 10 percent of ``construction risk zones'' for the local air basin, which comprises most of Los Angeles Los Angeles (lôs ăn`jələs, lŏs, ăn`jəlēz'), city (1990 pop. 3,485,398), seat of Los Angeles co., S Calif.; inc. 1850. , San Bernardino, Riverside and Orange counties.

The report, which was issued last week, estimated that construction-related equipment contributes to 1,100 premature deaths a year in the state. That includes deaths related to respiratory problems and cardiovascular conditions.

Emissions from construction equipment cause more than 700 premature deaths a year in the Southern California air basin that includes Santa Clarita, according to the report.

Mark Grey, director of environmental affairs for the Building Industry Association, disputed the report's findings -- but not having read the whole report he didn't go into detail.

``The document was clearly designed solely to grab media headlines, and it won't withstand close scrutiny and objective review,'' he said. ``They're just basically rehashing old information.''

Santa Clarita had 3,100 acres under construction last year, which was high for its population, Anair said. Those factors combined put Santa Clarita in the report's top ``construction risk zones.''

The California Air Resources Board California Air Resources Board (CARB) is the "clean air agency" of the state of California in the United States. Established originally in 1967, it is a part of the California Environmental Protection Agency, an organization which reports directly to the California is formulating new regulations that would apply to existing construction equipment instead of just newly bought equipment, which would be a first in the nation.

The agency estimates there are up to 180,000 pieces of construction equipment in the state. Construction equipment is expensive -- sometimes costing more than $1 million per piece of machinery -- and it can last for decades.

Those factors make construction companies reluctant to buy new, lower-polluting machines.

``Construction equipment is really kind of the final frontier for cleaning up diesel emissions,'' said Tudor Van Hampton, an editor with a publication called the Engineering News- Record.

``Now that the trucking industry has cleaned up their emissions so much, construction equipment is the next target,'' he said.

Particulate matter from diesel exhaust causes respiratory and cardiovascular problems by penetrating deep into the lungs and getting into the blood stream.

It also contributes to smog and elevated cancer risk.

Meanwhile, the report from the Massachusetts-based Union of Concerned Scientists pegs the loss of life and productivity associated with construction equipment to $5.9 billion for the South Coast Air Quality Management DistrictThe South Coast Air Quality Management District (SCAQMD), formed in 1976, is the air pollution agency responsible mainly for regulating stationary sources of air pollution for most of Los Angeles, San Bernardino, Riverside County, and all of Orange county.
