Current through Register Vol. 54, No. 28, July 13, 2024
(a) Impoundments or tanks for storing
						  leachate before or during treatment shall be constructed in accordance with
						  §§
													299.122,
						  299.142 and
						  299.145 (relating to storage
						  tanks; general requirements; and failure).
(b) An onsite leachate storage system shall
						  be part of each leachate treatment method used by the operator. The storage
						  system shall contain impoundments or tanks for storage of leachate. For
						  noncaptive facilities, the tanks or impoundments shall have a storage capacity
						  at least equal to the maximum expected production of leachate for a 30-day
						  period for the life of the facility estimated under §
													289.413 (relating to leachate
						  treatment plan). For captive facilities, the tank or impoundment shall have
						  sufficient storage capacity to ensure proper operation of the treatment
						  facility in accordance with the approved leachate treatment plan and shall meet
						  the performance standard in §
													289.438(a)(1)
						  (relating to leachate collection system within protective cover). No more than
						  25% of the total leachate storage capacity may be used for flow equalization on
						  a regular basis.
(c) The
						  impoundments or tanks shall be aerated as necessary to prevent and control
						  odors. Impoundments or tanks shall each have a capacity of at least 250,000
						  gallons, unless otherwise approved by the Department.
(d) The storage capacity of impoundments and
						  tanks at a site shall be increased, if additional storage is required, prior to
						  each major phase of construction and as otherwise necessary.
(e) Leachate storage capacity may not be
						  considered to include leachate that may have collected in or on the liner
						  system.
(f) Necessary collection
						  and containment systems shall be installed prior to the deposition of solid
						  waste at the site. The leachate treatment or handling system approved by the
						  Department under §
													289.413 shall be installed or
						  ready for use prior to the storage or disposal of solid waste at the
						  site.
(g) For areas permitted after
						  January 13, 2001, all underground pipes used for the transport of leachate from
						  the liner system to the leachate storage impoundments or tanks shall be
						  equipped with secondary containment or comply with the requirements in §
													245.445 (relating to methods for
						  release detection for piping). Secondary containment shall be designed,
						  constructed and installed to direct any release to an area that can be
						  inspected for leaks.
