Dust Management Plan 2019

Research Reviewed dust control plan from prior years and identified

  • pportunities for improvement.

Plan

  • Seal unused north side of coal field with sealant.
  • Utilize Water Tankers during the day and night for dust

suppression.

  • Conducted meetings with all crews to discuss our roles and

responsibilities.

  • Focus on proactive approach to dust control.

Dust Management Plan 2019

Plan

  • Integrate detailed weather forecast information which allows

us to be proactive in using our coal dust suppression tools effectively. Tools

  • Envirobind ET Sealant on Coal piles
  • Internet – Weather Forecast Website. Allows operators to be

proactive in using dust controls measures before winds pick up.

  • Water Tankers
  • Dozers and Graders
  • Sprinkler System

Dust Management Plan 2019 Sprinkler System

History

  • In 2016 we developed a sprinkler system for our coal field

with input from community stakeholders

  • Sprinkler system consisted of 3 towers. One per coal pile.

Today

  • Our 2019 sprinkler system consists of 7 towers and is

controlled via a computer system PLC which will operate automatically once set.

  • Sprinkler System is used in conjunction with our Water

Tankers for dust suppression.

  • Video of coal piles and sprinkler system.
