'fhe CAA at the Paducah Site is
administered by KDAQ. DOE has responsibility
only for air emission sources under DOE
program control; therefore, this report does not
address emissions from the PGDP sources leased
to USEC.
Airborne Effluent Monitoring Program
The two point sources of air emissions for
the Paducah Site in 1999 were the Northwest
Plume Groundwater System and the Northeast
Plume Containment System. These systems
combined removed 2,676 pounds (1.3 tons) of
TCE (a VOC) from the groundwater. These
facilities remove TCE contamination from the
groundwater by air stripping. At the Northwest
Plume Groundwater System, TCE-Iaden air
passes through carbon filtration which removes
much of the TCE. The air stream is then released
to the atmosphere where the remaining TCE
naturally breaks down.
The CAAdefines VOC emissions as
criteria pollutants. A minor source is limited to
100 tons per year of each criteria pollutant. If
greater quantities of criteria pollutants are
emitted, then the source is classified as a major
source. A minor source has less stringent permit
requirements because of the reduced potential
for health effects from the smaller amount of
emissions.
The CAA also limits the emissions from a
minor source of hazardous air pollutants (HAPs)
to 10 tons/ year for each individual pollutant and
25 tons/year for all HAPs combined. TCE is a
HAP. The greatest amount of HAP emitted in
1999 was less than the 2,676 pounds,(1.3 tons)
of TCE removed from the groundwater from the
combination of the Northwest Plume
Groundwater System and the Northeast Plume
Containment System.

Liquid Effluent Applicable Regulations
The CW A is administered for the Paducah
Site by KDOW through the KPDES Wastewater
Discharge Permitting· Program. The sitewide
KPDES permit (KY0004049) became effective
April 1, 1998, and will expire on March 31,
2003. This permit contains limits based on water
quality criteria for a zero~flow receiving stream.
KDWM specifies in landfill permits 073-
00014, 073-00015, and 073-00045 that surface
runoff be analyzed to ensure that landfill
constituents are not discharging into nearby
receiving streams.
Liquid Effluent Monitoring Program
DOE conducts nonradiological effluent
monitoring for outfalls under its jurisdiction
(Figure 4.1). Outfalls, 001, 015, 017, and 019
were monitored for KPDES permit parameters.
Title 40, Code of Federal Regulations, Part 136
(40 CFR 136), lists the specific sample
collection, preservation, and analytical methods
acceptable for the types of pollutants analyzed.
Preservation in the field is conducted per 40 CPR
136, and chain-of-custody procedures are
followed after collection and during transport to
the analytical laboratory. The samples are then
accepted by.the laboratory and analyzed per 40
CPR 136 procedures for the parameters required
by the KPDES permit.
Surface runoff from the closed C-746-S
residential landfill, the closed C-746-T inert
landfill, and the operating C-7 46-U landfill was
monitored quarterly. Grab samples were
monitored for chloride, sulfate, pH, sodium,
