Annual Site Environmental Report
ETTP discharges to the waters of the state of Tennessee under two individual NPDES permits: NPDES
Permit No. TN0002950 which regulates storm water discharges and NPDES Permit No. TN0074225
which regulates industrial discharges from CNF.
In 2009, compliance with the ETTP NPDES storm water permit was determined by approximately
835 laboratory analyses and field measurements. The NPDES permit compliance rate for all discharge
points for 2009 was nearly 100% with only one measurement exceeding numeric NPDES storm water
permit limits. The noncompliance occurred on January 6, 2009 at storm water outfall 340 where a
measured value of 9.1 Standard Units (SU) exceeded the maximum pH limit of 9.0 SU. No harm to
aquatic species was seen during investigation of the incident. The exceedance did not result in any
discernable ecological impact. Section 3.5 contains detailed information on the activities and programs
carried out at 2009 by ETTP in support of the CWA.
In 2009, compliance with the ETTP NPDES permit for industrial wastewater from CNF was
determined by more than 2000 laboratory analyses and field measurements. The CNF NPDES permit
compliance rate for 2009 was 100% with no occurrences of noncompliances.
3.3.7 Safe Drinking Water Act Compliance Status
ETTP’s water distribution system is designated as a Non-Transient, Non-Community water system by
TDEC’s Division of Water Supply. The Tennessee Regulations for Public Water Systems and Drinking
Water Quality, Chap. 1200-5-1, sets limits for biological contaminants and for chemical activities and
chemical contaminants. TDEC requires sampling for the following constituents for compliance with state
and federal regulations:
• chlorine residual levels,
• bacteriological (total coliform),
• lead and copper, and
• disinfectant by-products (trihalomethanes and haloacetic acids).
The city of Oak Ridge supplies potable water to the ETTP water distribution system and meets all
regulatory requirements for drinking water. The water treatment plant, located on the ORR, southwest of
the ETTP, is owned and operated by the city of Oak Ridge.
In 2009, sampling results for ETTP‘s water system chlorine residual levels, bacterial constituents,
disinfectant by-products, lead and copper were all within acceptable limits.
3.3.8 Resource Conservation and Recovery Act Compliance Status
ETTP is regulated as a large-quantity generator of hazardous waste because the facility generates
more than 1,000 kg of hazardous waste per month. This amount includes hazardous waste that is
generated under permitted activities (including repackaging or treatment residuals). At the end of 2009,
ETTP had approximately nine generator accumulation areas for hazardous or mixed waste.
ETTP is also regulated as a handler of universal waste (e.g., fluorescent lamps, batteries, and other
items regulated under 40 CFR 273). Mercury-containing equipment at ETTP is managed as universal
waste.
Additionally, some batteries are managed according to 40 CFR Part 266.80. This applies to the
management of spent lead-acid batteries that are being reclaimed.
ETTP is registered as a large-quantity generator under EPA ID No. TN 0890090004 and is permitted
to transport hazardous wastes and to operate RCRA-permitted hazardous waste treatment and storage
units. During 2009, 20 units operated as permitted units.
ETTP’s RCRA storage and treatment facilities (or units) operate under three permits: TNHW-117,
TNHW-133, and TNHW-015. The permits are modified when necessary. One permit modification was
approved by TDEC in 2009.
