5.0 SITE CONTROL PLANSOHM will implement <strong>site</strong> control <strong>plan</strong>s to prevent negatively impacting the surroundingenvironment while per<strong>for</strong>ming <strong>remediation</strong> activities. Three specific <strong>plan</strong>s that are discussed inthe following section are the following:lllErosion <strong>and</strong> Sedimentation PlanSpill Prevention <strong>and</strong> Control PlanS tormwater Management PlanPortions of these <strong>plan</strong>s will be implemented immediately once OHM mobilizes to the <strong>site</strong>,while other activities will be implemented as necessary. The following sections describe theactivities <strong>for</strong> each of these <strong>plan</strong>s.5.1 EROSION AND SEDIMENTATION CONTROL PLANThe Erosion <strong>and</strong> Sedimentation Control Plan (ESCP) has been prepared to provide measuresto protect nearby surface waters that could be negatively impacted by construction activities ifproper sediment <strong>and</strong> erosion protection measures are not taken within this area having easilyerodible s<strong>and</strong>y surface <strong>soil</strong>s. To protect against damage, storm water surface run-off leavingthe <strong>site</strong> will be controlled by temporary erosion/sediment control techniques such as berms, siltfencing <strong>and</strong> grading as shown in Figures 4 <strong>and</strong> 5. Open excavations or stockpiled <strong>soil</strong>vulnerable to creating erosion problems during construction activities will be held to aminimum.Silt fencing will be constructed around all high activity construction areas or excavation areaswhere off-<strong>site</strong> migration of <strong>soil</strong> may occur. Locations that will be protected downgradientinclude monitoring well locations, the two drainage ditches <strong>and</strong> B&son Creek.Mulch will be placed over <strong>and</strong> around natural <strong>and</strong> wooded areas that are disturbed duringexcavation activities. Areas which are not expected to be reclaimed by natural vegetation willbe seeded <strong>and</strong> mulched, sodded, <strong>and</strong>/or covered with seeded, biodegradable erosion controlmatting.Upon completion of backfilling <strong>and</strong> compaction activities, permanent seeding will beper<strong>for</strong>med over the affected areas, <strong>and</strong> any other areas where natural revegetation will notoccur or will not occur quickly.5.1.1 Construction Specifications1..
