15. Measurement of other contaminants: The person responsible for a petroleum refinery must also measure the aggregate amount of oil and grease, phenols, sulfide, ammonia nitrogen and suspended matter contained in the liquid effluents and storm water deposited in the environment by the refinery.
The contaminants contemplated in the first paragraph shall be measured on 3 non-consecutive days per week. The 3 days selected for the measurement of contaminants must always be the same, as stated in the declaration previously submitted to the Minister to that effect pursuant to section 16. The data thus obtained must be kept in a register for a period of 2 years. The register must also indicate the number of barrels of crude oil processed in the petroleum refinery on each day that the contaminants are measured.
Lastly, the person responsible for an existing petroleum refinery must, each week, for 3 non-consecutive days, measure the concentration of oil and grease present in the once-through cooling water deposited in the environment by such refinery.
