SCHEDULE 2 See Explanation 2 (c) after Rule 61-UP, Rule 61-UB (1) (b), 61-UC, 61-UD (1) (c) and (d) (a) The threshold quantities set out below relate to each installation or group of installations belonging to the same occupier where the distance between installations is not sufficient to avoid, in foreseeable circumstances, any aggravation of major accident hazards. These threshold quantities apply in any case to each group of installations belonging to the same occupier where the distance between the installations in less than 500 meters. (b) For the purpose 0£ determining the threshold quantity of hazardous chemical at an isolated storage, account shall also be taken of any hazardous Chemical which is :- (i) In that part of any pipeline under the control of the occupier having control of the site, which is within 500 meters of that site and connected to it; (ii) At any other site under the control of the same occupier any part of the boundary of which is within 500 meters of the said site; and (iii) In any vehicle, vessel, aircraft or hovercraft under the control of the same occupier which is used for storage purpose either at the site or within 500 meters of it. But no account shall be taken of any hazardous chemical which is in a vehicle, vessel, aircraft or hovercraft used for transporting it. Sl.
