When completing the following Dust Control Plan, use the Guidance For Application for Dust Control Permit - Section 3

- Instructions to help you select dust control measures and keep in mind the following:

• Categories and/or sub-categories of dust generating operations C3, C5, D1, F, and G, in the following Dust Control Plan, have primary control measures, “P”, required by Rule 310. You will need to choose a contingency measure, "C", for these dust generating operations. All sections need one P and one C.

• Where “Other” is listed without reference to opacity or surface stabilization standard(s) and is selected as a primary control measure, then the description must meet the criteria in the Guidance For Application For Dust Control Permit – Section 3 – Unlisted Dust Control Measures (See Guidance Page 12).

After your Application For Dust Control Permit has been approved, you must post your Dust

For each of the different project phases, indicate how the water is to be stored on or supplied to the project site and how the water will be applied to control dust generation throughout the project lifetime. “Water supply” means how water will be supplied to the site (e.g. (2) 3/000 gal. water towers). “Water application system” means how water will be applied to the site (e.g. 1 fire hose, (3) 1,000 gal. water trucks). Minimum water availability means water supply in conjunction with the water supply system.
