542.11The Department shall issue the approved copies of the soil erosion and sediment control plan after the applicant has submitted proof that each applicable fee for Department services has been paid.

 

542.12Following approval of the plan, the applicant shall request the Department’s approval at each of the following stages of construction:

 

(a) Installation of perimeter erosion and sediment controls, but before proceeding with any other earth disturbance or grading; and

 

(b) Final stabilization of the site before the removal of erosion and sediment controls. Final stabilization means that all land-disturbing activities at the site have been completed and either of the following two (2) criteria are met:

 

(1) A uniform (for example, evenly distributed, without large bare areas) perennial vegetative cover with a density of seventy percent (70%) of the native background vegetative cover for the area has been established on all unpaved areas and areas not covered by permanent structures, or
