Greenhouse operations, GNF or test solution
 60. (1) A controller of a greenhouse operation shall, if an event set out in Column 1 of the Table to this section occurs in respect of the operation, ensure that sampling and analysis is carried out to make the determinations set out opposite the event in Column 2 of the Table by applying the method set out opposite the event in Column 3 of the Table. O. Reg. 300/14, s. 60 (1); O. Reg. 234/15, s. 25 (1). (2) Subsection (1) applies in respect of an event described in Column 1 of Item 4 only if the greenhouse operation is subject to a GNF strategy and no determinations are made in the calendar year in respect of an event described in Column 1 of Item 2 or 3 at the greenhouse operation. Table   Sampling and Analysis for greenhouse operations  Item   Column 1 Event   Column 2 Determinations   Column 3 Method 

  1.   Preparation of GNF strategy for the greenhouse operation at a time other than at time of registration.   Concentration of each Category 1 parameter in the GNF generated at the operation.   1. Determine the average of the results from a minimum of three samples and all available samples of the GNF taken during the 12 months before the submission of the GNF strategy. 2. If none of the GNF is available during the 12 months before the submission of the GNF strategy, determine the average of the results from a minimum of three samples and all available samples of test solution taken during the 12 months before the submission of the GNF strategy. 

  2.   The first occurrence of one of the following events following the registration of the greenhouse operation: 1. GNF generated at the greenhouse operation is applied to land within the farm unit of the operation. 2. GNF generated at the greenhouse operation is transported from the farm unit of the operation to an agricultural operation on a different farm unit.   Concentration of each Category 1 parameter in the GNF generated at the operation.   1. Determine the average of the results from a minimum of three samples and all available samples of the GNF taken during the two months before the event date. 2. If none of the GNF is available during the two months before the event date, determine the average of the results from a minimum of three samples and all available samples of test solution taken during the two months before the event date. 

  3.   Renewal of registration of the greenhouse operation.   Concentration of each Category 1 parameter in the GNF generated at the operation.   1. If , in the year in which the renewal is required, there is a date on which GNF is applied to land within the farm unit of the operation or transported from the farm unit of the operation to an agricultural operation on a different farm unit, determine the average of the results from,   i. a minimum of three samples and all available samples of the GNF taken during the year, at least three of which must be taken and analyzed within two months before the first of those dates, or   ii. if none of the GNF is available during the two months before the first of those dates, a minimum of three samples and all available samples of test solution taken during the year, at least three of which must be taken and analyzed within two months before the first of those dates. 2. If, in the year in which the renewal is required, no GNF generated at the operation is applied to land within the farm unit of the operation or transported from the farm unit of the operation to an agricultural operation on a different farm unit, paragraph 1 applies, except for the requirement that samples be taken and analyzed within the specified two-month period. 

  4.   Subject to subsection (2), the first occurrence of one of the following events in a calendar year: 1. GNF generated at the greenhouse operation is applied to land within the farm unit of the operation. 2. GNF generated at the greenhouse operation is transported from the farm unit of the operation to an agricultural operation on a different farm unit.   Concentration of each Category 2 parameter in the GNF generated at the operation.   1. Determine the average of the results from a minimum of one sample and all available samples of the GNF taken during the two months before the event. 2. If none of the GNF is available during the two months before the event, determine the average of the results from a minimum of one sample and all available samples of test solution taken during the two months before the event.
