ARM 17.24.640. DISCHARGE STRUCTURES

(1) Discharge from sedimentation ponds, impoundments, and diversions must be controlled by vegetation, energy dissipators, riprap channels, and other measures, where necessary, to reduce erosion, to prevent deepening or enlargement of stream channels, and to minimize disturbance of the hydrologic balance. Discharge structures must be designed according to standard engineering-design procedures and be certified by a qualified, registered, professional engineer as meeting the performance standards of this subchapter and any design criteria specified by the department.
