§ 288.555. Leachate collection and storage.
(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 § 288.513 (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 § 288.537(a)(2) (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. A leachate treatment or handling system approved by the Department under § 288.513 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.
