Page 5 February 5, 1997 unreasonable as determined by the MPCA. Dust pollutives shall be utilized to the extent necessary on cover material such as stockpiles to reduce wind erosion as well as on other exposed surfaces as appropriate. Cover compaction and revegetation activities shall be undertaken promptly on the completion of various fill areas and vegetative cover capable of quick growth shall be utilized. Planting of bushes and trees shall be installed if needed to buffer the Site and minimize wind erosion. An all-weather haul road shall be provided to the unloading area and watered on a regular basis. The Landfill shall pave the access roads from T.H. 169 to the scale and from T.H. 169 to the shop building by June 30, 1997 to reduce dust generation. All equipment and vehicles utilized at the Landfill Site shall be periodically inspected and maintained to minimize noise. Vegetative barriers along the boundaries of the Landfill Site shall be utilized to minimize off-site noise impacts. Applicable state standards for noise pollution shall not be exceeded by the Landfill operation, equipment, vehicles or machinery. The Permittee shall take reasonable actions to control odors from the Site. Part Ill.7. - Heavy Metal Contaminant Monitorina and Assessment (new item). Heavy metal contaminants for surface water and groundwater must be addressed in addition to VOC contaminants. Based on the need for additional monitoring to confirm exceedances and identify trends, the Landfill shall conduct monitoring and prepare an evaluation report which shall be submitted with the Phase IV Water Quality Monitoring Report. Part III. C. - Corrective Action. If heavy metal concentrations in groundwater and surface water exceed regulatory standards, the Permittee will be required to conduct a Feasibility Study and submit it to MPCA within six months of completing the Phase IV Water Quality Monitoring Report. Part IV.C.2. - Leak Detection Lvsimeters Leachate monitoring of the lysimeters should identify an acceptable leakage rate in consideration of the liner design and an allowable efficiency of 95 %. Leakage rates above this level should trigger sampling and subsequent remedial action. The requirement for 100% efficiency of the liner system is not consistent with other MPCA requirements. Part VI.A. - Closure The draft permit should include the requirement of a post-closure road for maintenance of the final cover. The road should extent to the highest elevation of the fill area. Overall, MPCA has developed a draft permit which incorporates many of the concerns that the City of Elk River has previously expressed. The inclusion of the above language in the draft permit will cover a broader perspective of the Landfill design and operation and may reduce the City's need for regulatory oversight in the future.
