148. Any increase in the annual production of phosphorous (P2O5) on a raising site, and the subsequent operation of the site, requires authorization pursuant to subparagraph 10 of the first paragraph of section 22 of the Act or, where applicable, the amendment of such authorization pursuant to subparagraph 5 of the first paragraph of section 30 of the Act,
(1) unless, following the increase, production remains below 4,200 kg and the increase is eligible for a declaration of compliance in accordance with section 150;
(2) if, following the increase, production is equal to or greater than 4,200 kg, or 4,200 kg increased by 1,000 kg or a multiple of 1,000 kg, calculated as follows: [4,200 kg + (1,000 kg x 1, 2, 3, 4, etc.)].
Despite the first paragraph, where an increase is such that more than one threshold will be reached or exceeded, only the highest threshold reached or exceeded requires authorization or an amendment of authorization. In addition, authorization for reaching or exceeding a threshold is valid until authorization or an amendment of authorization is required for an increase that is such that a higher subsequent threshold is reached or exceeded.
This section does not apply to an increase in the annual production of phosphorous (P2O5) within the limits set in an authorization issued prior to 5 August 2010.
