37. (1) Each discharger shall keep records, in an electronic format acceptable to the Director, of all analytical results obtained under sections 19 to 23, 25, 32, 33 and 33.1, all calculations performed under sections 12 to 15, and all determinations and calculations made or performed under sections 34 and 35.  O. Reg. 64/95, s. 37 (1); O. Reg. 523/95, s. 9 (1). (2) Each discharger shall keep records of all sampling and analytical procedures used in meeting the requirements of section 7, including, for each sample, the date, the time of pick-up, the sampling procedures used and any incidents likely to affect the analytical results. (3) Each discharger shall keep records of the results of all monitoring performed under sections 24, 26, 27 and 31. (4) Each discharger shall keep records of all maintenance and calibration procedures performed under section 34. (5) Each discharger shall keep records of all problems or malfunctions, including those related to sampling, analysis, acute lethality testing, chronic toxicity testing or flow measurement, that result or are likely to result in a failure to comply with a requirement of this Regulation, stating the date, duration and cause of each malfunction and including a description of any remedial action taken. (6) Each discharger shall keep records of any incident in which effluent that would ordinarily flow past a sampling point established under this Regulation is discharged from the discharger’s plant without flowing past that sampling point, stating the date, duration, cause and nature of each incident. (7) Each discharger shall keep records of all process changes and redirections of or changes in the character of effluent streams that affect the quality of effluent at any sampling point established under this Regulation at the discharger’s plant. (8) Beginning on March 1, 1995, each discharger shall calculate and keep records of the reference daily rate of production, in tonnes, for each material listed in the Table for the discharger’s plant in Schedule 10.  O. Reg. 64/95, s. 37 (2-8); O. Reg. 311/17, s. 12. (9) Beginning on March 1, 1995, each discharger shall calculate and keep records of monthly average daily production, in tonnes, of each material listed in Schedule 11 for the discharger’s plant, for each month.

(10) For the purposes of subsection (9), the monthly average daily production of a material for a month at the discharger’s plant is the amount of the material, calculated in tonnes, that is produced at the discharger’s plant during the month, divided by the number of days in the month. (11) For the purposes of subsection (8), the reference daily rate of production for a material at the discharger’s plant is the arithmetic mean of the amounts calculated under subsection (9) for the material for the first 12 months for which the discharger is required to keep a record for the material under subsection (9). (12) Subject to subsection (13), each discharger shall make each record required by this section as soon as reasonably possible and shall keep each such record for a period of three years.
