3	The format of Table 1 has been revised to distinguish between recommended threshold quantities proposed for regulation and other emergency hazards for information only.
3	For Petroleum (Petroleum crude oil) (CAS # 8002-05-9) and Crude oil (oil sand) (Synthetic crude oil) (CAS # 128683-25-0), the vapour cloud explosion emergency hazard has been rounded to 10,600 tonnes in Table 1.
3	For Naphtha (petroleum), sweetened (CAS # 64741-87-3), the threshold quantity when the boiling point is ≥ 35°C has been rounded to 80.00 tonnes in Table 1.
3	For Naphtha (petroleum), full-range alkylate butane-containing (CAS # 68527-27-5), the recommended threshold quantity has been rounded to 80.00 tonnes in Table 1.
9	The paragraph under “Findings” in subsection 2.6 has been changed to: In accordance with the lower-tier threshold from SEVESO and supported by modeling data for pool fires, the quantity threshold of 2,500 tonnes is recommended for all substances in Table 1, except for the following: Naphtha (petroleum), sweetened (CAS No. 64741-87-3), which has the potential to cause vapour cloud explosions, has a recommended threshold quantity of 4.5 tonnes when the boiling point is less than 35°C and 80 tonnes when the boiling point is equal to or greater than 35°C; Naphtha (petroleum), full-range alkylate butane-containing (CAS No. 68527-27-5) has a threshold quantity of 80 tonnes due to its potential to cause vapour cloud explosions; and, For the natural gas condensates, the thresholds are 340, 4.5, and 45 tonnes for 64741-47-5, 64741-48-6 and 68919-39-1, respectively, due to their potential to cause vapour cloud explosions.
