INFORMATION ON RECYCLED ASPHALT PAVEMENT (RAP)
Gary Hague, Environmental Health Manager, from Clear Creek County met with the town staff to discuss the recycled asphalt millings (RAP). Gary informed the staff that OSHA does not classify RAP as dangerous, and there are no uses that are advised against. He explained that we do not live in an area that has an acid rain concerns and therefore, the runoff levels from the millings are not a threat. He said that it would take approximately the amount of 94 bathtubs full, in a confined space, for long periods of time, before causing any potential health concerns. Gary provided the town staff with a study completed by the EPA which stated that the RAP must have extended exposure to a strong heat source to create toxic levels. However, the exposure to sunlight does not generate enough heat to create these levels. According to the EPA report, if anything is leached from the asphalt millings, it would be below limit values for drinking water and pose a limited risk. He stated that everything has a level of toxicity including water, however, the EPA and the county look at the acceptable levels, and therefore are not concerned with RAP use or long-term storage.
According to the U.S Department of Transportation Federal Highway Administration, environmental stewardship is designated as a major focus area of the United States Department of Transportation (DOT) strategic plan. According to the Environmental Protection Agency (EPA), environmental stewardship is the responsibility for environmental quality shared by all those whose actions affect the environment. The Federal Highway Administration (FHWA) supports and promotes the use of recycled highway materials in pavement construction in an effort to preserve the natural environment, reduce waste, and provide a cost-effective material for constructing highways. In fact, the primary objective is to encourage the use of recycled materials in the construction of highways to the maximum economical and practical extent possible with equal or improved performance. As part of the FHWA recycled materials policy, the FHWA actively promotes asphalt pavement recycling and technology.
