25 Pa. Code § 88.99 - Hydrologic balance: discharge structures
Discharge from dams, ponds, embankments, impoundments and diversions shall be controlled by energy dissipators, riprap channels or other devices, where necessary, to reduce erosion, to prevent deepening or enlargement of streamchannels and to minimize disturbance of the hydrologic balance. Discharge structures shall be designed according to standard engineering-design procedures.
