Wherever heavy equipment is hard at work, sooty exhaust smoke is sure to follow. According to a story on Post-Gazette.com, a typical 175-horsepower bulldozer puts out the same amount of air pollution as 500 cars.
The grimy image of heavy equipment is soon to change with new 2007 emission standards for diesel equipment and trucks. Equipment owners and users are adapting their machines to comply with the new rules that take effect next year.
To fight harmful particles from diesel soot, heavy equipment can be retrofitted with special filters called scrubbers. These scrubbers can reduce emissions by 90%, but they do not come cheap. Installing scrubbers on one piece of equipment can cost up to $15,000. Replacing engines on heavy equipment costs even more.
The expense of upgrading and adapting to the new 2007 emission standards does have a benefit. Because heavy equipment is cleaner, developers and builders finding more public support for large construction projects. Cleaner heavy equipment will soon be at work at New York’s Ground Zero, when construction begins on the new Freedom Tower.
