As part of the Army National Guard NPDES Multi-Sector General Permit for various sectors, CEI was contracted to complete quarterly site inspections, visual monitoring, and annual reviews of each facility maintaining this type of NPDES permit. CEI provided a review of each drainage sub-basin and associated daily activities taking place within each area pertaining to hazardous materials and potential stormwater impacts. Additionally, where applicable, CEI completed stormwater sampling of running discharges for visual examination that included documentation of odor, clarity, color, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution. CEI provided site inspections for multiple DOD facilities and bases on a regular basis. As part of this, CEI completed site interviews regarding daily use and provided recommendations to help each facility maintain compliance with NPDES Federal permits.
