4. A summary of the Best Management Practices utilized at the permitted facility. Summary
should consist of a short narrative description of each BMP's in place at the facility. If
the implementation of any BMP's is planned, please include information on these BMP's.
From the NIEHS Stormwater Pollution Prevention Plan:
Structural BMPs
A. Oil -Water Separators:
Building 101 C Oil -Water Separator
Building 101F Oil -Water Separator
Building 105 Oil -Water Separator
The oil/water separators are designed to capture residual oil from any leaks that may occur in the
associated fuel oil storage tank containment basins. All containment drain valves remain closed
and locked until collected stormwater can be visually evaluated for sheen and discoloration.
Stormwater releases occur weekly or as needed with records kept in a logbook.
B. Secondary & Other Containments:
Building 101 C Fuel Oil Storage Tank
Building 101F Fuel Oil Storage Tank
Building 102 Fuel Oil Storage Tank
Building 105 Fuel Oil Storage Tanks
Building 105 Generator Day Tank
Building 105 Cooling Tower Basins
Building 108 Trench Drain
The fuel oil storage tank containments are designed to hold the entire contents of the largest tank
in the containment plus the 25-year rain event. All containments are inspected weekly by the
NVT utility contractors. All containment drain valves remain closed and locked until collected
stormwater can be evaluated for sheen and discoloration. The cooling tower basins located east
of Building 105 are designed to contain cooling water and minimize overspray. The Building
108 loading area is equipped with a trench drain for containment of spills that could occur during
chemical waste transfer between the waste truck and the loading dock. The trench drain valve
remains closed at all times except to release collected stormwater following a visual evaluation.
C. Riprap Areas:
North Parking Lot Outfall Riprap
Journal Lane Sluiceway Riprap
F-Module Outfall Rip -Rap Basin
Building 108 Outfall/Sluiceway Riprap (north side of Building 108)
Building 105 Outfall/Sluiceway Riprap (south side of Building 108)

required if the HSB determines that the runoff is potentially hazardous to the environment.
Water discharged during fire hydrant and sprinkler system flushing is also authorized. Efforts
must be made to limit the potential for erosion caused by hydrant and sprinkler system flushing.
Potable water
Discharge of uncontaminated potable or city water is authorized. This includes water that is
flushed, leaking, or otherwise discharged from the domestic or city water system. Large potable
water leaks that discharge into the NIEHS Lake must be reported to the HSB. Routine washing
of building exteriors, windows, and loading docks with potable water is authorized as long as no
detergents are used. Potable water may also be used to rinse vehicles as long as water use is
minimized to limit the volume of water discharged to the storm drain system
Air conditioning & atmospheric condensate
Discharge of uncontaminated air conditioning condensate is authorized. Uncontaminated water
discharged from atmospheric condensation and from foundation drains is also authorized.
Valve pits/utility vaults groundwater pumping
The pumping of uncontaminated groundwater from valve pits and utility vaults into storm drains
or onto the ground is authorized. Efforts must be made to limit the potential for erosion caused
by surface water runoff from groundwater pumping.
Landscape watering
The watering of plants and vegetation in the landscaped areas on the NIEHS campus is
authorized. Landscape watering should be efficiently directed in order to limit overspray and
avoid discharges into storm drains.
(ii) Unauthorized Non-stormwater Discharges:
Sanitary sewer system overflows
Sanitary sewer system overflows must be reported to the NIEHS Security office at 1-2800. It is
recommended that wastewater from the overflowing manhole be pumped to the nearest
downstream manhole to reduce the release volume. Efforts should be made to reduce
wastewater discharge from upstream sources during overflow events. Also, wastewater must not
be pumped out of the overflowing manhole onto the ground in an effort to evaluate sewer line
conditions. The Durham County Sewer Use Ordinance states that vacuuming must occur with
any jetting of the sewer lines. The sewer line is defined as the piping that receives wastewater
from the various building lines. The HSB Environmental Compliance Officer is responsible for
notifying Durham County and the NC Division of Water Quality of any changed condition or
discharge to the environment. The HSB Environmental Compliance Officer is also responsible
for submitting a press release to all. Durham County print and electronic news media if an
untreated wastewater discharge of 1000 gallons or more enters the NIEHS Lake. The HSB
and/or the ORF landscape contract project officer are responsible for disinfecting the spill site
through application of hydrated lime and removal of excess solids.

5. A short narrative describing any significant changes in industrial activities at the
permitted facility. Significant changes could include the addition or deletion of work
processes, changes in material handling practices, changes in material storage practices,
and/or changes in the raw materials used by the facility.
Industrial Activity Additions:
The NIEHS installed a 500 gallon capacity sulfuric acid (50%) storage tank inside Building 105.
The sulfuric acid is used as part of a reverse osmosis water treatment process. Deliveries occur
about twice per year and are limited to 375 gallons. Stormwater runoff from the sulfuric acid
receiving station discharges to the Building 105 outfall. The NIEHS has developed a Standard
Operating Procedure for receiving sulfuric acid. The SOP is focused on spill prevention and
personal protective equipment.
Industrial Activity Deletions:
The E85 aboveground storage tank and associated fuel dispensing station installed to provide
alternative fuel (85% ethanol / 15% gasoline) for the NIEHS fleet vehicles is no longer in use.
Tanker truck deliveries of E85 have not occurred since 2010.
There have been no other significant changes in industrial activities at the NIEHS during the
current permit term.
