§ 91.35. Wastewater impoundments.

 (a)  Except as otherwise provided under subsections (c) and (d), a person may not operate, maintain or use or permit the operation, maintenance or use of a wastewater impoundment for the production, processing, storage, treatment or disposal of pollutants unless the wastewater impoundment is structurally sound, impermeable, protected from unauthorized acts of third parties, and is maintained so that a freeboard of at least 2 feet remains at all times. The person owning, operating or possessing a wastewater impoundment has the burden of satisfying the Department that the wastewater impoundment complies with these requirements.

 (b)  A person owning, operating or in possession of an existing wastewater impoundment containing pollutants, or intending to construct or use a wastewater impoundment, shall promptly submit to the Department a report or plan setting forth the location, size, construction and contents of the wastewater impoundment and other information as the Department may require.

 (c)  Except when a wastewater impoundment is already approved under an existing permit from the Department, a permit from the Department is required approving the location, construction, use, operation and maintenance of a wastewater impoundment subject to subsection (a) in the following cases:

   (1)  If a variance is requested from the requirements in subsection (a).

   (2)  If the capacity of one wastewater impoundment or of two or more interconnected wastewater impoundments exceeds 250,000 gallons.

   (3)  If the total capacity of polluting substances contained in wastewater impoundments on one tract or related tracts of land exceeds 500,000 gallons.

   (4)  If the Department determines that a permit is necessary for effective regulation to insure that pollution will not result from the use, operation or maintenance of the wastewater impoundment.

 (d)  This section does not apply to:

   (1)  Manure storage facilities at agricultural operations, which are governed by §  91.36 (relating to pollution control and prevention at agricultural operations).

   (2)  Residual waste processing, disposal, treatment, collection, storage or transportation.
