On-Site Asphalt Batch Plant Releases Steam Throughout Day

Neighbors may notice steam from the Chimney Hollow Reservoir site, which is from our on-site asphalt batch plant. Steam is released when asphalt is made throughout the day and also at the end of the day when the asphalt batch plant is cleaned. The steam may look like smoke or dust but is instead the steam produced from the asphalt plant. 

On Saturday, Oct. 15, crews placed the first section of the asphalt core. The asphalt will be placed in 10-inch lifts until it reaches the top of the dam (approximately 350 feet). Rockfill is occurring concurrently to stabilize the asphalt core. This process will continue for approximately two-and-a-half years and will total over 500 lifts of asphalt.

Once completed, Chimney Hollow Reservoir will be one of about 200 asphalt-core dams worldwide, only the second built in the United States, and by far the tallest asphalt-core dam in the country.
