for Rad NESHAPs compliance. An estimated 0.0081 Ci (0.7 kg) of uranium was released into the
atmosphere in 2009 as a result of Y-12 activities (Figs. 4.18 and 4.19).

Quality assurance activities for the Rad NESHAP program are documented in Y-12 National Security
Complex Quality Assurance Project Plan for National Emission Standards for Hazardous Air Pollutants
(NESHAPs) for Radionuclide Emission Measurements (Y-12 2005). The plan satisfies the quality
assurance (QA) requirements in 40 CFR Part 61, Method 114 (CFR 2007), for ensuring that the
radionuclide air emission measurements from the Y-12 Complex are representative to known levels of
precision and accuracy and that administrative controls are in place to ensure prompt response when
emission measurements indicate an increase over normal radionuclide emissions. The requirements are
also referenced in TDEC regulation 1200-3-11-.08. The plan ensures the quality of the Y-12 radionuclide
emission measurements data from the continuous samplers, breakthrough monitors, and minor
radionuclide release points. It specifies the procedures for the management of the activities affecting the
quality of the data. The QA objectives for completeness, sensitivity, accuracy, and precision are
discussed. Major programmatic elements addressed in the QA plan are the sampling and monitoring
program, emission characterization, the analytical program, and minor source emission estimates.
4.4.1.4 Source-Specific Criteria Pollutants
Proper maintenance and operation of a number of control devices (e.g., HEPA filters, baghouses, and
scrubbers) are key to controlling emissions of criteria pollutants. The primary source of criteria pollutants
at the Y-12 Complex is the steam plant, where coal and natural gas are burned. Information regarding
actual vs. allowable emissions from the steam plant is provided in Table 4.7. The Y-12 Title V operating
