§ 285.123. Impoundments—general.

 A person or municipality storing municipal waste in a surface impoundment shall:

   (1)  Comply with Chapter 105 (relating to dam safety and waterway management).

   (2)  Design and maintain the impoundment to prevent the dispersal of municipal waste by wind and water erosion, and to prevent odors.

   (3)  Design and maintain sufficient freeboard to prevent overtopping. There shall be at least 2 feet of freeboard unless otherwise approved by the Department, in writing.

   (4)  Construct and maintain a protective cover sufficient to minimize wind and water erosion and preserve structural integrity, including, but not limited to, suitable vegetation, rock riprap or nonerodible material.

   (5)  Design and maintain sufficient structural integrity to prevent failure.

   (6)  Design and maintain dikes or berms so that the outside slope does not exceed 33% unless otherwise approved by the Department, in writing.

   (7)  Design and maintain structures around impoundments sufficient to prevent surface runoff from entering the impoundment, based on the maximum surface runoff from a 25-year, 24-hour precipitation event.

   (8)  Design and maintain dikes or berms to be free of burrowing mammals and plants with root systems capable of displacing earthen materials upon which the structural integrity of the dikes or berms is dependent.

   (9)  For leachate storage:

     (i)   Install and maintain a liner that meets the requirements of Chapter 273 (relating to municipal waste landfills).

     (ii)   Design, install and operate a groundwater monitoring system that meets the requirements of Chapter 273.

   (10)  For sewage sludge storage impoundments constructed after January 25, 1997:

     (i)   Install and maintain a liner system that meets the requirements of § §  273.253—273.257, unless otherwise approved by the Department in a permit.

     (ii)   Install and operate a groundwater monitoring system that meets the requirements in § §  273.281—273.288 (relating to water quality monitoring), unless otherwise approved by the Department in a permit.
