MITIGATION MEASURES PROPOSED TO MINIMIZE POTENTIAL SIGNIFICANT EFFECTS TOPOGRAPHY Measures Proposed by Applicant • The proposed final surface elevations of the site will not exceed 10 feet above the existing Harney Lane elevation. Other Possible Measures • Revise the proposed final elevation to not exceed some level which is less than 10 feet above the existing Harney Lane elevation and which takes into account the probable amount of settling which will occur as the refuse decomposes. However, this would reduce the useful life of the landfill operation. • Locate tree plantings about the periphery of the site, as appropriate, to obscure the visual impact of this unnatural topographicaly feature. SOILS Measures Proposed by Applicant • Since mounds of daily cover material must be stockpiled for daily use throughout the year, some erosion of this material cannot reasonably be avoided. Due to this, all runoff from the site would be collected in ditches and channeled o a common, temporary sediment basin near the north end of the site. The sediment basin would be designed to retain particules 0.02 mm in diameter and larger. Periodic cleaning out of the sediment basin would be necessary to maintain its effective- ness. • Although revegetation of closed disposal trenches is proposed, specific details about the type and procedure are not available at this time. Other Possible Measures • Prior to excavation for the construction of a disposal trench or a portion of a trench, the top 18 inches of soil should be skimmed from the area to be affected and stockpiled and protected from erosion. This is to prevent loss of topso _ r later use as the top layer of the final cover. Top- soil shoul be be wasted for daily cover material. .Lj-
