closure of each phase of the Landfill. This Permit does not obligate the Licensee <br /> to apply for or City to approve of a particular end use plan. <br /> 9.) Specific Additional Requirements. <br /> (01) Leachate and LFG Condensate Transmission Pipes. Leachate and LFG <br /> condensate transmission pipes shall be designed to ensure that double <br /> containment and adequate leak detection exists as approved by the MPGA, <br /> County and City. Licensee shall verify to the City every four (4)years that the <br /> existing leachate transmission pipes do not leak. <br /> (02) Backup Leachate Pumps. Licensee shall maintain backup pumps for use in <br /> the event of pump failure at the leachate sump, wet well and/or leachate storage <br /> tank on-site. As an alternative, the licensee shall maintain provisions for restoring <br /> temporary leachate pumping within a 24-hour period and adhere to the current <br /> "Leachate Management Plan" as approved by MPGA. <br /> (03) Leachate Holding Tank. Licensee shall ensure that the leachate holding <br /> tank is pumped out on a regular schedule. It is a violation of this License to allow <br /> leachate to collect on the liner to a depth exceeding one foot due to the leachate <br /> holding tank being full. <br /> (04) Leachate Recirculation. The Licensee may conduct Leachate <br /> Recirculation pursuant to MPGA, County and City regulations. In the event that <br /> operational problems occur from the leachate recirculation, the Licensee shall <br /> immediately cease leachate recirculation and revert to prior method of leachate <br /> management unless and until another remedy for the problem is approved by the <br /> City. Leachate recirculation will greatly increase the amount of landfill gas that <br /> will be generated from the landfill. The primary concerns relate to landfill gas <br /> collection and the prevention of fugitive gas emissions and odors. <br /> (a) Temporary final cover is proposed as an element of the March <br /> 2012 "Leachate Recirculation Plan. ERL will provide a summary <br /> of related activities in the annual operating report. <br /> (b) ERL has proposed that the leachate cleanout risers will be <br /> perforated along a portion of the sideslope. ERL has committed to <br /> conduct active extraction from cleanout risers. <br /> (c) There have been a number of leachate seeps which have occurred <br /> in recent years. Documentation on the precise location of seeps <br /> has not been developed. This information is critical in potential <br /> problem resolution during later stages of landfill operation. The <br /> documentation of the seeps must include an approximate <br /> coordinate position with an elevation. This would also enable a <br /> 7 <br />
