on and mn-Off controls. The drainage and erosion plans sha[t be submitted to the Planning D~partment with review by the Director of Public Works. The operator may proceed with proposed construction within ten (10) calendar days of the Planning Department'~s receipt of written submittal unless otherwise notified by the Planning Department. The plans should incorporate the following measures: (a) The proposed landfill shall be constructed against existing ridges such that all rainfhll on areas adjacent to the footprint shall drain away from the landfill. (b) Sedimentation basins shall be incorporated into the project design in places where peak discharges would increase substantially. (c) Drainage facilities shall be constructed to accommodate the 1,000 year, 24- hour storm, or current design storm as required by state or federal law. 47. 48. In the eventi that springs or heavy seeps are encountered during site excavation for the landfill, add!tional subgrade drainage measures shall be taken to ensure that there is no seepage into the landfill and that groundwater/waste separation is maintained. Such measures m~ty include additional geotextile drains, the extension of gravel chimney drains up th¢ slope from the gravel drain on the floor of the landfill, and hydroaugers. Other meashres also may be recommended by the project engineering geologist in response to the local hydrogeological conditions. The operato~ shall design the final grading and drainage of the Proposed Class II Landfill Expansion tO minimize cover erosion. Design features shall include deck area slopes to promote sheet drainage, a series of drainage benches, inlets, and down drains, debris/ retention basins, and outlet structures. PUBLIC HEALTH ? SAFETY 49. The operatok shall continue the application of the existing WMAC/ALRRF Special Waste Program (a process of identifying and characterizing each customer waste stream) to new designated wastes to be received by ALRRF. Designated wastes shall be accepted only from pre-approved generators. To be pre-approved, a generator shall submit information that may include analytical data to the operator demonstrating that its waste stream is nbn-hazardous prior to sending any waste to the landfill. Wastes with ambiguous analytical data (indicating that it could be hazardous) shall not be accepted by the operatorlfor disposal at the landfill until the waste is proven to be non-hazardous by supplemental testing. This measure would allow the landfill to employ inexpensive screening te~ts that could flag wastes that are potentially hazardous without rejecting them outrigt~t, while allowing definitely nonhazardous wastes to pass. Waste proven to be hazardous either by the screening tests or by supplemental tests shall be taken elsewhere. 50. In accordange with State codes, any truck which disposes of municipal solid waste (MSW) at the ALRRF may be inspected and approved or rejected by the LEA. In 17-B Final Altamont Settlement - Exhibit B
