The Environmental Protection Agency is developing an alternative approach to demolishing <br />structures that contain asbestos. The current standard, outlined in the EPA's National <br />Emission Standard for Hazardous Air Pollutants, requires that buildings be sealed in plastic <br />and that specially trained crews in protective suits remove most of the asbestos-contaminated <br />materials by hand before the building is demolished. <br />The alternative <br />The EPA's proposed Alternative Asbestos Control Method would allow crews to leave the <br />asbestos-contaminated materials in the building during demolition. They would have to wet the <br />inside of the structure with a foaming material before, during and after demolition and to <br />remove as much as 3 inches of soil that may have been saturated with foam that contains <br />asbestos. Crews would have to wear respirators and protective gear during the procedure. The <br />alternative is similar to the controversial "Fort Worth method" abandoned by the EPA two <br />years ago. Instead of foam, that method called for wetting the structure with water. <br />The concern <br />Leaving asbestos-laden material in the building during demolition creates the possibility of <br />asbestos fibers wafting into the air and, depending on wind direction and speed, traveling <br />far from the site. That could expose many people to asbestos a fibrous mineral that can <br />scar the lungs and cause cancer. <br />Why it's important <br />If the test in Fort Worth works, it could have national implications. The EPA says it could <br />amend federal regulations governing the demolition of asbestos-contaminated structures to <br />include the alternative procedure. That is why public health officials, asbestos experts and <br />environmentalists nationwide are watching the case closely. <br />Previous tests <br />The EPA has tested the proposed alternative method twice before. The first test, in April <br />2006, was deemed inconclusive by experts appointed by the agency. They strongly questioned <br />some of the report's statements. In particular, the experts said the conclusions that the <br />amount of asbestos measured in the air was not a health concern hinted at "a research bias or <br />hidden agenda." A second test, conducted in ]uly at Fort Chaffee, is also being reviewed, <br />with a report expected early next year. <br />The site <br />The Oak Hollow apartment complex will be the first test of the alternative method in a <br />residential area. Only a 2,200-square-foot apartment management office building will be <br />demolished using the alternative method. The city will later demolish the rest of the complex <br />using the currently approved federal method. <br />What's next <br />The EPA plans to begin the experiment next week. It's scheduled to wet down the office <br />building with the foam Tuesday, then demolish the building Dec. 12. The federal agency will <br />analy2e dozens of air, soil, dust and pavement samples and issue a report by May. The agency <br />will then appoint a panel to peer-review the report and release a final report by the end of <br />2008. <br />Source: Environmental Protection Agency <br />3 <br />5~ ~ C-) <br />
