PART 1Authorization to Deposit (continued)

Reporting (continued)

Combined Sewer Overflow Report

Marginal note:Information

 The owner or operator of a wastewater system that includes at least one combined sewer overflow point must, in accordance with subsections 19(4) and (5), send to the authorization officer a combined sewer overflow report in respect of each calendar year by February 15 of the following calendar year and the report must contain the following information:

  • (a) for each month of the calendar year during which effluent was deposited via a combined sewer overflow point, the information referred to in subparagraphs 17(b)(iii) and (iv); and

  • (b) for each month of the calendar year during which effluent was not deposited via a combined sewer overflow point, a statement indicating that no effluent was deposited via an overflow point during the month.

Record Making and Retention of Documents

Marginal note:When records made

 Records must be made without delay after the information to be recorded becomes available.

Marginal note:Retention of records

  •  (1) An owner or operator of a wastewater system must keep a report referred to in section 17, as well as a record and a copy of a report required to be sent under these Regulations — along with any supporting documents — for at least five years after the day on which the record or report, as the case may be, was made.

  • Marginal note:Place of retention

    (2) The report referred to in section 17, the record and the copy must be kept at the wastewater system or at any other place in Canada where it can be inspected. If that report, record or copy is kept at one of those other places, the owner or operator must provide the authorization officer with information specifying that other place, including its civic address, if any.

  • Marginal note:Information on monitoring equipment and identification report

    (3) Despite subsection (1), the information referred to in paragraph 17(c) must be kept for at least five years after the day on which the monitoring equipment ceased to be used, and the identification report, as it may be updated from time to time, referred to in section 18 must be kept for at least five years after the wastewater system is decommissioned.
