The base or bottom of the impoundment shall be at least two feet above the seasonal high water table. Adequate freeboard shall be provided and maintained to accommodate any anticipated variability in design flow and the accumulated precipitation from a 10 year, 24 hour storm.
At its discretion, the Department may require more stringent liner requirements when deemed necessary to protect human health and the environment. In addition, the owner or operator of a surface impoundment may be required to develop and maintain a groundwater monitoring program to evaluate the facility's impact upon groundwater.
