Technical Basis
A review of available sources identified exposure limits (ERPGs, TWAs, STELs, IDLH) and various acute toxicity data. The ERPGs were selected due to their priority among Protective Action Criteria (Section 1).
• PAC-1 = ERPG-1
• PAC-2 = ERPG-2
• PAC-3 = ERPG-3
This review generated PAC values consistent with Rev. 29A*.
• PAC-1 = ERPG-1
• PAC-2 = ERPG-2
• PAC-3 = ERPG-3
This review generated PAC values consistent with Rev. 29A*.
