   3. (3) The project does not involve the construction of gravel roads or impervious cover of more than 10,000 square feet.
2. (b) For excavation or mining of earth materials projects, the applicant shall submit an excavation, grading, and reclamation plan, as specified in Env-Wq 1504.03.
3. (c) The applicant shall submit a steep slope erosion and sediment control plan, as specified in Env-Wq 1504.04, for any project that requires an AOT permit based solely on meeting the criteria specified in Env-Wq 1502.58(c).

7. (g) For any project that includes privately owned roads or parking lots that might result in a discharge of stormwater to a surface water of the state impaired for chloride, the applicant shall:
