Technical Basis
Analysts used DOE recommended methods, using accepted multiplying factors listed in Table 3.5: Dose basis =10 ppm
TEEL-1 = TLV-TWA (10 ppm)*3
TEEL-2 = TEEL-1*11
TEEL-3 = TEEL-2*6
TEELs were rounded to two significant figures and converted from referenced units to either ppm or mg/m3, providing both values.
The review did not result in a change from the values in Rev. 29A
