ContractorsScientists say pollution from heavy equipment kills
thousands
Where automobiles are concerned, California has the most
stringent air-pollution controls in the nation. Construction
equipment, however, is a different story: Pollution from the
180,000 bulldozers, excavators, and earth-movers that carve out
the state's roads and housing developments has largely escaped
notice — until now.
In December, the Union of Concerned Scientists (UCS) released a
study that blames emissions from diesel-powered construction
equipment for an estimated 1,132 premature deaths in 2005 in
California alone. The group also concluded that as many as
30,000 asthma attacks and 183,000 lost workdays during the same
year were caused by construction pollution, resulting in a
total cost to the state's economy of more than $9
billion.
"Construction pollution is taking a heavy toll on the health of
all Californians," says Don Anair, an engineer with UCS and the
author of the report. "The construction equipment being used to
build our hospitals shouldn't be responsible for filling them
up."
The problem with diesel exhaust is not so much the heavy black
soot that makes people cough and sneeze as it is microscopic
particulates that evade the body's natural defenses and burrow
deep into the lungs, causing inflammation and scarring, and
increasing the risk of cancer. The smallest particles can get
absorbed into the bloodstream and contribute to cardiovascular
illnesses.
According to scientists, an excavator
like this one generates as much pollution in an hour as a
tractor-trailer does traveling from Los Angeles to
Seattle.
Although the EPA has subjected manufacturers of diesel engines
for large trucks and buses to strict emission controls since
1988, comparable standards for off-road construction equipment
won't start being phased in until 2008. One result of the
lagging engine standards, Anair points out, is that a typical
bulldozer, backhoe, or excavator emits more pollution in a
single hour than a modern tractor-trailer does while traveling
1,000 miles.
This form of pollution may prove to be more complicated to
reduce than car and truck emissions, however. Because the
machines are built to last for decades — and are very
expensive to replace — the UCS study predicts that, by
themselves, the federal new vehicle standards won't yield
results until 2030. To speed up the cleanup, the group
recommends retiring the oldest equipment, replacing the engines
on middle-aged machines, and retrofitting newer models with
modern emission-control devices. (For owners who want to make
their construction equipment cleaner than what's currently
mandated, the California EPA provides grants through the Carl
Moyer Incentives Program. Go to www.calepa.ca.gov for more
information.)
In the meantime, the California Air Resources Board is drafting
measures that will require owners of existing off-road
construction vehicles to reduce their emissions of diesel
particulates. Those regulations may go into effect as early as
2009.

Construction Pollution in California," is available on the

Offcuts
••••November sales of new single-family
homes rose at a seasonally adjusted rate of 3.4 percent over
October's dismal figures, reports the Commerce Department. Many
industry experts caution that the change does not necessarily
indicate an upturn in the market; rather, they attribute the
increase to buyers taking advantage of generous incentives
offered by builders trying to reduce inventories of unsold
homes. As proof, they note that November's sales were 15.3
percent lower than those of a year ago.
••••After 19 years as the state with the
nation's fastest growing population, Nevada has been bumped to
No. 2 on the list. The new leader? Arizona. Numbers from the
U.S. Census Bureau indicate that between July 1, 2005, and July
1, 2006, the Grand Canyon State's population rose 3.6 percent
— compared with a paltry 3.5 percent for Nevada. In sheer
numbers, Texas — which added 579,275 people during that
period — was the winner, followed by Florida and
California, each of which gained more than 300,000 people. Not
surprisingly, Louisiana was the big loser. Nearly one year
after Hurricane Katrina, that state's population was down by
almost 220,000 people, a 4.9 percent decline from the previous
year.
••••An unemployed framer in Little Rock,
Ark., dressed himself as a border patrol agent in November to
intimidate workers he believed were in the country illegally,
reports the Arkansas Democrat-Gazette. Carl Dean Wynn Jr. is
also accused of sending threatening letters to their employer,
builder Graham Smith, who notified the police. Wynn was
arrested and charged with harassment and misdemeanor criminal
mischief. Upon his arrest, police found bullet-resistant vests,
Border Patrol T-shirts and badges, and dozens of four-pointed
spikes that Smith claims were used to flatten tires in front of
his business. Smith says that while all of his workers are
legal, he can't vouch for his subcontractors' employees.
••••Upscale garages are in and spiral
stairs are out. That's the word from real estate trend-watcher
Mark Nash, who polled 923 real estate professionals for his
survey "What's In, What's Out With Home Buyers in 2007." Nash
says today's buyers want finished garage spaces equipped with
cabinets, hvac, and a refrigerator. They also covet heated
patios, two home offices, and a "rejuvenation room," described
as a calming exercise and meditation space with a spa and
shower. Poll respondents judged spiral staircases passé
(aging boomers don't want to climb them and they're tricky for
children and pets). Ditto for bowl-shaped above-the-counter
bathroom sinks (too hard to clean) and glass-filled kitchen
cabinet doors (don't hide the clutter).
••••Concrete is not just for foundations
anymore. A recent study by NAHB and the Portland Cement
Association reveals that in 2005 nearly 18 percent of all new
single-family homes were framed using an above-grade concrete
building system. In addition to concrete masonry units and
cast-in-place concrete, popular systems include ICFs, precast
panels, and autoclaved aerated concrete.
••••A partnership composed of many of the
nation's largest banks and philanthropic institutions is
calling on the president and Congress to come up with a better
plan to revitalize America's cities. In addition to asking for
more federal dollars and longer-term commitments to fund worthy
projects, Living Cities wants the government to loosen
restrictions on how local jurisdictions can spend that money.
Funded by the Ford, Rockefeller, MacArthur, and Annie E. Casey
foundations, among others, Living Cities (www.livingcities.org)
has invested $375 million in America's cities since its
founding in 1991.
••••Apparently the world's largest
home-improvement retailer is not content to merely buy
boatloads of product from China. In an effort to establish a
sales presence in the world's most populous country, Home Depot
announced in December that it was acquiring Home Way, a Chinese
home-improvement chain with 12 stores in six cities. This
latest round of expansion comes after earlier forays into
Canada (1994) and Mexico (2001). Today the company claims to
hold the No. 1 position in both of those markets.
Paint Manufacturers Face
More Lead-Related Lawsuits
In January, the city of Los Angeles joined a number of other
California municipalities in a class-action lawsuit against 10
companies that formerly manufactured lead-based paint. The suit
alleges that Sherwin-Williams, DuPont, Glidden, and others knew
about the toxic nature of their products but deliberately
concealed this information from the public.
San Diego, Oakland, and San Francisco are also party to the
lawsuit, which seeks to force the manufacturers to contribute
to a fund that will pay for the abatement of lead hazards in
homes and buildings throughout the state.
Similar legal actions are under way in Ohio. There, six cities
— including Canton, Columbus, and Cincinnati —
rushed to file lawsuits before the end of the year following
the General Assembly's passage of a bill severely restricting
the ability to sue paint manufacturers; the new measure
requires that plaintiffs prove that manufacturers made the
specific paint in each building that poses a health
hazard.
Until now municipalities around the country have sidestepped
such formidable burdens of proof by arguing that if it can be
proved that a company sold a significant amount of lead-based
paint within the jurisdiction, it should be held accountable
for creating a public nuisance.
That's what happened in Rhode Island. Last February, in a
landmark decision, a jury there found three former
manufacturers of lead-based paint (Sherwin-Williams, NL
Industries, and Millennium Holdings) guilty of creating a
public nuisance. It's now up to a judge to determine damages;
meanwhile, the affected companies are contesting the
verdict.
And in Missouri, the city of St. Louis is using the
public-nuisance argument to hold paint manufacturers Benjamin
Moore, PPG Industries, and XBD Inc. — as well as the
three companies convicted in Rhode Island — accountable.
Although a lower-court judge initially rejected this claim, the
state Supreme Court has agreed to consider the matter. —

Georgia to License
Building Contractors
On January 1, 2008, the dwindling number of states that
allow contractors to practice without a license will be reduced
by at least one. In Georgia, from that date forward, no one
will be allowed to pull a building permit for any job costing
more than $2,500 without first presenting a valid contractor's
license.
According to the new regulations, contractors can apply to be
licensed under one of the following three
classifications:
• Residential-Basic, which allows for work on one-family
and two-family houses and townhouses;
• Residential-Light Commercial, which comprises all of the
above plus multifamily housing and light commercial
projects;
• General Contractor, which allows for unlimited types of
work — excepting specialty trades, such as plumbing and
electrical, that already require separate licensure.
The fee to apply for any of these licenses will be $200. Among
other requirements, applicants must show proof that they carry
workers' compensation plus specific levels of general liability
insurance, and achieve a score of at least 70 on a two-part
examination. And applicants for the general contractor license
must have a minimum net worth of $150,000, as well as a $50,000
line of credit. — T.O.
