§ 89.24. Sedimentation ponds.
(a) Sedimentation ponds, when required, shall be constructed in accordance with this section and Subchapter D (relating to structural requirements for impoundments) before disturbing the contributory drainage area. The ponds shall be located as near as possible to the area to be disturbed and out of perennial and intermittent stream channels, unless approved by the Department.
(b) A nonclogging dewatering device shall be installed to remove storm water. This device shall have a discharge rate to achieve and maintain the required detention time.
(c) Sedimentation ponds shall be operated and maintained until the disturbed area has been stabilized and revegetated and removal is approved by the Department. The ponds may not be removed sooner than 2 years after the last augmented seeding unless the Department finds that the disturbed area has been sufficiently revegetated and stabilized.
