(c) Any other major equipment.

(D) Environmental and aviation compliance information. The applicant shall provide:

(1) A list and brief discussion of all permits that will be required for construction of the facility.

(2) A description, quantification and characterization of debris that will result from construction of the facility, and the plans for disposal of the debris.

(3) A discussion of the process that will be used to control storm water and minimize erosion during construction and restoration of soils, wetlands, and streams disturbed as a result of construction of the facility.

(4) A discussion of plans for disposition of contaminated soil and hazardous materials generated or encountered during construction.

(5) The height of tallest anticipated above ground structures. For construction activities within the vicinity of airports or landing strips, provide the maximum possible height of construction equipment as well as all installed above ground structures.

(6) A description of the plans for construction during excessively dusty or excessively muddy soil conditions.
