Ariz. Admin. Code § R11-2-602 - Erosion Control and Topographic Contouring

A. Mining units shall be reclaimed to a stable condition for erosion and seismic activity.

B. Grading and other topographic contouring methods shall be conducted, as necessary, to establish final land forms which are:

1. Suitable for the post-mining land use objective in the approved reclamation plan.

2. Stable under static and dynamic conditions as certified by a qualified engineer considering the following:

a. Site-specific seismic conditions;

b. Safety consistent with good engineering practices; and

c. The hazard to public safety, if failure occurs.

C. Site-specific grading, revegetation, or other proposed erosion-control measures shall be conducted, as necessary, to address erosion so that permanent piles of mine development rock, overburden, and tailings shall not restrict surface drainages in a manner that contributes to excessive erosion or which compromises the stability of the reclaimed facility.
