Best Management Practices (BMP) Summary
Locked Storm Water Outfall Gates - only specific trained personnel are allowed to open the outfall gates after
following the draining procedure which involves evaluating the storm water and completing a storm water drain
clearance form.
Locked Secondary Containment Areas - the three secondary containment areas that can be drained to the storm
water outfall drainage area are locked closed. Only specific trained personnel are allowed to open the secondary
containment areas after following the draining procedure which involves evaluating the storm water and
completing a storm water drain clearance form.
Spill Response Kits - several spill kits are located throughout the facility.
Limit Exposure - chemicals are not stored in the storm water outfall drainage area unless there is secondary
containment. Also there is a truck station in the storm water drainage area with secondary containment that
drains to a sump that flows to waste water treatment system in order to capture any potential drips during the
connecting/disconnecting of the trailers.
Methanol Truck Unloading Station Design - the unloading station has secondary containment that drains into a
sump. The sump is only drained after trained personnel follow the draining procedure which involves evaluating
the water and completing a storm water drain clearance form.
Sediment and Erosion Control - currently there are no operations that routinely occur that warrant erosion and
sedimentation controls. A determination of the need for erosion and sedimentation control measures will be
made when any activity at the facility disturbs the existing ground surface.
