Kingston Ash Release

Dust Suppression

Since January, several actions to decrease the potential for airborne dust have been taken. Those actions include:

  • Spreading more than 85 tons of winter rye grass seed and 12-24-24 fertilizer as well as 650 tons of straw.
  • Application of a vinyl acrylic emulsion blend liquid dust suppression agent on the ash dredge cell.
  • Spreading of erosion control mulch on the ash dredge cell
  • Installation of over 268 acres of Flexterra on the ash.
  • Installation of test plots of a warm weather grass seed to test for germination and dust control.
  • Spraying the on-site haul roads, the portions of the public roads that are used by construction equipment, and the stone being unloaded from trucks with water.
  • Installation of two wheel-wash stations at strategic locations near the Kingston site, with input on the locations from TDEC and local officials.
  • Instructions to trucking contractors to drive at acceptable speeds.
  • Continuing to monitor the ash around the site and add dust control measures as necessary to keep dust from becoming airborne. 

A presentation on air monitoring and dust control was made to the Tennessee Air Pollution Board on April 6, 2009. View the presentation.
