Technical Basis
A review of limited sources identified a Level of Concern (LOC). The TEEL-2 continues to be based on the EPA’s LOC. TEEL-3 and TEEL-1 values were calculated according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = LOC (9 mg/m3)
• TEEL-3 = TEEL-2 x 6
This review generated values in this review are consistent with those published in Rev. 29A.
