The Minister may allocate to a licensee:

  (a)   an HCFC quota for a quota period; or

  (b)   in exceptional circumstances, a reserve HCFC quota for a specified period (which need not be a quota period).

Under section   18, it is a condition of a controlled substances licence that:

  (a)   the licensee must not engage in a regulated HCFC activity unless the licensee has been allocated a quota; and

  (b)   the total quantity of HCFCs involved in regulated HCFC activities engaged in by the licensee is not more than the licensee's quotas.

Sections   24 and 25 limit how much quota the Minister may allocate.
