STORMWATER MANAGEMENT AND BMP SUMMARY
2.3 Secondary Containment
Concrete block secondary containment walls are provided around the West Tank Farm,
Production Pad Area, Utility Area (tanks) and South tank Farm. Each of the four
containment areas on these pads are equipped with a sump pit and pump. The Railside
Tank Farm does have concrete block containment but without the sump pump system.
Procedures for releasing stormwater accumulating in these areas will be described in the
Spill Prevention and Response section below.
2.4 Best Management Practices (BMPs)
A Stormwater Management system has been designed, permitted and constructed.
Stormwater will be conveyed through swales to a wet detention pond. After drawdown,
runoff will be conveyed by outlet spreader through a vegetated filter strip.
There is a stormwater pond that is currently in use on site. The pond is designed to catch
runnoff from the ground's natural slope.
Stormwater collected from ADI's tank areas and sampled to determine if it is to be
released or must be treated. The following chart shows the requirements for water to be
discharged.

If sampled stormwater that does not meet the standards listed in their stormwater permit,
then it is pumped to Tank 50 where it is enters a cleaning process. The stormwater is air
stripped to remove volatiles, then it is run through a sand filter. At this point it is ready to
be retested and sent to POTW if below the discharge limits.

Stormwater that meets the stated discharge limits is discharged through a swale that runs
into the Cartwheel Branch Creek.
Inspection of Stormwater Conveyances
The following procedure will be used to limit or prevent erosion associated with
stormwater systems.
A) 1. Periodic inspections (semi-annual minimum) will be performed on the entire
stormwater system in conjunction with log sheets
2. A Log sheet will contain:
Date and time
Signature of inspector
Work order number for any required repairs
Work required under remarks
Work completed date
3. These records will be kept in the main control room for a period of five years.
B) All tanks and equipment will be inspected during the 6 A.M. daily inventory for any
signs of leakage. Any leaks detected will be reported as outlined in the spill
prevention/response program in this manual.
C) A preventative maintenance program is outlined in the American Distillation, Inc.
Process Safety Management (PSM) manual for process equipment reliability.
