the Structural BMP.
Location: East of building 205 in Drainage Zone 3B
Materials: Hazardous waste, solid wastes, empty drums, boxes of
methanol, plastic totes of aqua ammonia, fuel, and
plastic totes of hydrogen peroxide
Structural BMPs: The hazardous waste storage pad has a full roof and
walls on the north, east, and south sides. There are 4
separate bays segregated by a short knee wall. This
area also has a concrete pad that has epoxy coating and
is sealed with "Waterstop". The base is sloped to 4
separate collection trenches in the rear of the storage
area. There is also a speed bump on the western side
that is open for roadway access and prevents rainwater
from running onto the pad.
Hazardous Waste Storage Pad
Procedural BMPs: Incompatible wastes/materials are segregated and not
(S-20)
placed within the same storage bay. Hazardous and
solid wastes materials are generally stored in
appropriate new containers depending on the nature of
the hazardous waste or hazardous material to ensure no
incompatible materials stored in the same bay. When
using 55-gallon drums, the drums that are sealed are
then placed four to a pallet (maximum) with all drums
touching to prevent tipping. Provisions are made to
stack drums at safe heights and adequate aisle space is
maintained between the pallets. Stormwater
accumulation in the drainage trenches at the base of the
pad is typically evaporates. Should excess stormwater
accumulate in this trench, a vac truck collects the
stormwater and transports to the WWTP for disposal.

Location: On the north side of the #2 fuel oil aboveground storage tank
(S-3) in Drainage Zone 3B
Materials: No. #2 fuel oil
Structural BMPs: Top loading/unloading operations are conducted at this truck
loading/unloading station. The station, consisting of concrete
dike walls on the east and west sides, concrete ramps on the
north and south sides (68' x 13 % and a trench drain and sump
at the low point has sufficient capacity to contain the volume of
one compartment of a 7,500 gallon tanker truck plus freeboard
for rain accumulation. An operator is present at all times during
No. 2 Fuel Oil/Caustic Unloading Area
unloading operations and any leaks or failures in the hoses, etc.
(L-9)
would be corrected immediately.
Procedural BMPs: Before unloading procedures begin, Utility operators make sure
that wheels are chocked, that the vessel is in good condition, the
vessel is vented (if it is pressurized), and that the hoses, pumps,
and lines do not have leaks in accordance with area -specific
fuel unloading procedure in the site's Oil SPCC Plan (see Table
1, S-3). Operators also monitor the levels of materials in the
tanks to prevent overflow and spill. The sump is pumped to the
stormwater ditch located west across the roadway. A lock has
been placed on the sump pumpin this area.
Location: On the eastern side of building 100 in Drainage Zone 3B
Loading/Unloading Dock at Building 100

Structural BMPs: Each of the two-loading/unloading areas has a sloped concrete
pad, berms around the concrete pad, and a sump with a total
capacity of approximately 3,500 gal. The sumps have pumps
with float switches that pump collected materials to MASL
Tank # 1. This provides enough containment for the volume of
one compartment of a tanker truck plus rainwater accumulation.
Procedural BMPs: Truck drivers are responsible for implementing procedures to
minimize the likelihood of a release from the truck loading
MASL Loading
operation. Before loading/unloading procedures begin, drivers
(L-11)
make sure that wheels are chocked, that the vessel is in good
condition, the vessel is vented (if it is pressurized), the vessel is
grounded (if it contains flammable or combustible material),
and that the hoses, pumps, and lines do not have leaks. A
metered loading system automates the loading process and
minimizes the possibility of overfill. Drivers are responsible for
checking the track valve to ensure it is secure before leaving the
site. Failure to comply will ban the driver from receiving any
future loads of MASL. Accumulated water is generally
pumped to MASL Tank # 1.
