PART 2Transitional and Temporary Authorizations to Deposit (continued)

Temporary Authorization to Deposit Un-ionized Ammonia (continued)

Scope of Temporary Authorization and Revocation

Marginal note:Period and content

 A temporary authorization, and any extension of it, to deposit effluent that contains un-ionized ammonia must be in the form set out in Schedule 5 and contain the following information:

  • (a) the information referred to in paragraphs 35(a) and (c);

  • (b) the latitude and longitude of the final discharge point;

  • (c) the date of issuance of the temporary authorization and of any extension of it;

  • (d) the period of authorization; and

  • (e) a statement that the concentration of un-ionized ammonia in the water must be less than or equal to 0.016 mg/L, expressed as nitrogen (N), determined in accordance with subsection 34(3), at all points that are 100 m downstream from the point of entry where effluent is deposited in that water via the final discharge point.

Marginal note:Extension

  •  (1) A temporary authorization may, on application, be extended for successive periods of three years. If that application is based on a determination of the acute lethality of effluent referred to in paragraph 34(1)(a), it must contain the information referred to in subparagraph 35(e)(i).

  • Marginal note:Issuance

    (2) The authorization officer must — based on the information contained in the application for the extension, the monitoring reports sent under subsection 19(1) and the original application for the temporary authorization referred to in section 35 — extend the authorization if it is established that, when the application for an extension was made,

    • (a) the effluent was acutely lethal because of the concentration of un-ionized ammonia in it; and

    • (b) the concentration of un-ionized ammonia in the water, determined in accordance with subsection 34(3), at any point that is 100 m downstream from the point of entry where effluent was deposited in that water via the final discharge point was less than or equal to 0.016 mg/L, expressed as nitrogen (N).

Marginal note:Correction of information

  •  (1) If the owner or operator becomes aware that the information provided in an application for a temporary authorization, or for an extension of a temporary authorization, contains errors, they must, without delay, send a notice to the authorization officer, which indicates the reason for the errors and provides corrections, and make the certification under paragraph 35(g) with respect to the corrected application.

  • Marginal note:Corrected temporary authorization

    (2) On receipt of a notice that provides corrections that, if provided with the application, would have affected the scope of the information referred to in section 39, the authorization officer must issue a corrected temporary authorization or corrected extension of a temporary authorization, as the case may be, as if the corrections together with the remaining information originally provided in the application were an application under section 35 or 40.

Marginal note:Revocation

  •  (1) The authorization officer may revoke a temporary authorization, or an extended temporary authorization, to deposit effluent that contains un-ionized ammonia if

    • (a) the information contained in, as the case may be, the application for the temporary authorization referred to in section 35 or the application for the extended temporary authorization referred to in 40 is false or misleading in a material respect;

    • (b) the holder has, during the period of authorization, failed to comply with paragraph 37(a) or (b), any section referred to in paragraph 38(a), or paragraph 38(b) or (c); or

    • (c) new information indicates that a deposit under the temporary authorization or the extended temporary authorization has had or is likely to have an effect on fish, fish habitat or the use by man of fish that is more adverse than the worst of those effects that were anticipated when that authorization was issued.

  • Marginal note:Considerations

    (2) When determining whether to revoke a temporary authorization or an extended temporary authorization, the authorization officer must consider, as applicable, whether the holder

    • (a) has a history of non-compliance with any provision referred to in paragraph (1)(b); or

    • (b) has carried out, or signed an undertaking to carry out, specified corrective measures to ensure compliance with any provision referred to in paragraph (1)(b) or to prevent or mitigate a more adverse effect referred to in paragraph (1)(c).

  • Marginal note:Representations

    (3) The authorization officer is not permitted to revoke a temporary authorization or an extended temporary authorization unless they have provided the holder with

    • (a) written reasons for the proposed revocation; and

    • (b) an opportunity to be heard, by written representation, in respect of the proposed revocation.
