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.
