(Dallas, Texas – August 14, 2008) Chat owners and buyers can learn more about buying, selling and using chat from the Tar Creek area at a workshop scheduled for August 19, from 5-8 p.m. at the Miami Convention Center, in Miami, Oklahoma.

The intent of the workshop is to ensure chat sales from the Tar Creek Superfund site continue and comply with the federal Chat Rule.

Officials from the Environmental Protection Agency, as well as representatives from the Oklahoma Department of Environmental Quality, Bureau of Indian Affairs, U.S. Department of the Interior and the Quapaw Tribe will present information at the workshop. EPA has established that chat from the Tar Creek area can be used safely as an aggregate in asphalt and cement road surfaces. Chat also has beneficial uses in non-transportation, non-residential concrete and cement projects, such as commercial foundations, side walks, and parking areas.

Chat sales are a significant part of EPA cleanup plans for Tar Creek. Ottawa County, Oklahoma, contains more than 50 million tons of chat.
