Technical Basis
A review of available sources identified AEGL-2 and AEGL-3 exposure limits for this chemical. The AEGLs were selected as the TEELs due to their priority among the emergency exposure limits (Section 1). An AEGL-1 is not recommended for this chemical and therefore the TEEL-1 was derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values inconsistent with Rev. 29A. The Rev. 29A and current TEELs report the same sources, AEGLs; therefore, it is unclear why the Rev. 29A values differ from those reported by the EPA/NAS.
