4  Threshold quantity of more than one hazardous chemical
  If there is more than one hazardous chemical, a threshold quantity of chemicals exists where, if a number of chemicals are present, the result of the following aggregation formula exceeds 1:

where:
 (a) x, y, [....] and n are the hazardous chemicals present or likely to be present;
 (b) qx, qy, [....] and qn is the total quantity of hazardous chemicals x, y, [....] and n present or likely to be present, other than:
 (i) a hazardous chemical that is present or likely to be present in an isolated quantity less than 2% of its threshold quantity;
 (ii) hazardous chemicals that are solely the subject of intermediate temporary storage, while in transit by road or rail (unless it is reasonably foreseeable that, despite the transitory nature of the storage, hazardous chemicals are or are likely to be present frequently or in significant quantities);
 (c) Qx, Qy, [....] and Qn is the individual threshold quantity for each hazardous chemical x, y, [....] and n;
 (d) a hazardous chemical is present or likely to be present in an isolated quantity, for subparagraph (b)(i), if its location at the facility is such that it cannot, on its own, act as an initiator of a major incident.
