Culvert <br />pFecement and grade, outlet protection, and adequate compaction of fill materials will be closely <br />monitored. Particular attention will be paid to perimeter erosion control and sediment <br />structures. <br />Road drainage features will be monitored on a monthly basis during the operational phase of <br />the project. Inspections will pay close attention to the relative stability of concentrated flow <br />structures, drains and outlets. The stability of drainage structures ar critical junctions, such as <br />the transitions betwcen disturbed and undisturbed areas, will be given special attention. During <br />all phases road maintenance items will be prioritized and timely performed. <br />4.7.3 Soil Management <br />In the development and reclamation phases, soil monitoring will focus on proper placement of <br />diversions and runoff controls to protect the soil resourcx and avoid needless losses to erosion. <br />Inspections will be perfomred weekly or more frequently during salvage and reconstruction <br />operations to ensure that erosion and sediment control structures and practices are functional <br />and adequate. The selective handling, storage and replacement of topsoil materials will also be <br />monitored. Special attention will be paid to soil stockpile areas to ensure that erosion control <br />and protection measures are adequate. During the operational phase, stockpile erosion and <br />sediment control monitoring will be performed in the spring and fall and after significant <br />precipitation events. Corrective measures and maintenance items will be prioritized and timely <br />performed based on these inspections. <br />4.7.4 Grading <br />Inspections will be performed periodically during all phases of the project to ensure that <br />earthmoving activities remain within ffie perimeter of the controlled disturbance area. During <br />reclamation phases, inspections will focus on the creation of positive drainage in the <br />postmining topography and on proper construction and placement of permanent drainage <br />structures to provide stability. <br />' 4.7.5 Interim Vegetation Monitoring <br />Two interrelated but distinctly different types of monitoring will be performed on revegetated <br />' areas. Interim monitoring will be conducted to qualitatively evaluate the germination, <br />establishment and growth of temporary and permanent vegetation on soil stockpiles, within <br />drainage structures, on road cuts and fills, on erosion and sediment control structures, and <br />' within recently seeded pemranently revegetated areas. Revegetation success monitoring will be <br />performed after revegetated areas have established themselves and a restored area is ready for <br />final release from reclamation performance liabilities. Interim revegetation inspections are <br />described in this subsection. <br />' During or towards the end of the first full growing season following temporary, interim or <br />permanent revegetation operations, reseeded areas will be monitored for adequate germination <br />' and establishment, and to identify problem areas. Stand gemmnation and establishment may <br />take several growing seasons before full expression of the seed mixture is realized. <br />Inspections will focus on surface hydrologic stability and on the adequacy of vegetation <br />1 Moaicm Soda.
