%DEL Estimated Exposure Duration as a % of full year Estimated Annual Dose (millirem) from Effluents Generated During Remediation Less than NESHAP Standard?

Asbestos Work Area 3401 Asbestos Work Area 2590A NOTES: 1) The Action Level concentrations are set to 20% of the values published in Columns I & II of Table 2 of 10CFR 20 Appendix B. The raw Appendix B values are equivalent to the radionuclide concentrations which if inhaled or ingested continuously over the course of a year, would produce a total effective dose equivalent (TEDE) of 50 millirem (mrem) per year. The reduction to 20% of these values allows consistency with the U.S Environmental Protection Agencys (USEPA) 10 mrem/yr standard for effluent releases published in 40 CFR Part 61, Sections 92 & 102 (NESHAP).

2) The effluent air filter samples on several days during remediation activities exceeded the environmental effluent limit of 10% of the applicable Derived Effluent Limit (DEL) (1.00E-14 microcuries per cubic centimeter [uCi/cc]). Run times and count times for filters were often not adequate to achieve the MDAs less than 10% of the applicable DEL. Therefore, an assessment was performed to compare the weighted average concentration to the DEL. As a conservative approach the weighted average air concentration uses the higher of the reported result or MDA for each sample.
