O.C. 797-2019, s. 2.
2.10. Where the reception of contaminated soils is covered by a declaration of compliance or exempted from the application of section 22 of the Environment Quality Act (chapter Q-2), the owner of the land where the soils are received, or the owner’s representative, must, before receiving the soils, verify their acceptability.
To that end, the owner or representative must, upon arrival of the soils, enter in a logbook the following information:
(1)  the address of the soils’ land of origin;
(2)  the contact information of the carrier of soils;
(3)  the date on which the soils are received;
(4)  their quantity, expressed in m3;
(5)  the nature and concentration of the contaminants they contain, established on the basis of the analysis reports referred to in the third paragraph.
The owner or representative must also attach to the logbook the analysis reports that were used to perform the characterization study of the soils that their owner must give to them.
Where the reception of the owner’s soils is covered by a declaration of compliance, the owner of the land or representative must also, when receiving the soils,
(1)  for each batch of soils accepted less than or equal to 100 m3, collect a sample and have it analyzed;
(2)  for each batch of soils accepted greater than 100 m3, collect an additional sample and have it analyzed for each additional fraction of soils less than or equal to 200 m3.

O.C. 216-2003, s. 3; O.C. 797-2019, s. 3.
CHAPTER VI
MONITORING OF GROUNDWATER QUALITY
O.C. 797-2019, s. 4.
4. The carrying on on land of an industrial or commercial activity in a category listed in Schedule IV is subject to the monitoring of groundwater quality, in accordance with the following provisions, if a withdrawal facility for surface or groundwater intended for human consumption is situated less than 1 km downstream from the land.
Where the withdrawal facility referred to in the first paragraph is built after the industrial or commercial activity has begun, the groundwater monitoring requirement applies only after the expiry of the sixth month following the date on which the person carrying on the activity is informed of the existence of the installation.
The groundwater monitoring requirement prescribed by this section does not apply if it is shown that the industrial or commercial activity carried on on the land is not likely to alter the quality of the water referred to in the first paragraph by substances listed in Schedule V. If that demonstration is based in whole or in part on the land’s prevailing hydrogeological conditions, it must be signed by an engineer or a geologist who is a member of an order governed by the Professional Code (chapter C-26).
O.C. 216-2003, s. 4; I.N. 2019-12-01.
5. The purpose of the monitoring of groundwater quality prescribed in section 4 must be to
(1)  determine the land’s prevailing hydrogeological conditions;
(2)  identify the substances listed in Schedule V that are likely to be emitted on or in the land as a consequence of the carrying on on the land of certain industrial or commercial activities referred to in the first paragraph of section 4, and locate on the land the points of emission of the substances; and
(3)  verify the presence of the substances in the groundwater where the water reaches the boundaries of the land and, where applicable, their concentration.
O.C. 216-2003, s. 5.
6. In order to monitor groundwater quality as required by sections 4 and 5, a monitoring well system must be installed on the land concerned.
The number and location of the monitoring wells in such a system, as well as the number of sampling points that each well must have depends on the area of the land, the prevailing hydrogeological conditions and the number and location of the points of emission of the substances referred to in paragraph 2 of section 5.
O.C. 216-2003, s. 6.
7. At least 3 times a year, in the spring, summer and fall, the groundwater must be sampled at each sampling point of the monitoring wells established for the purposes of section 6 in order to perform the verification referred to in paragraph 3 of section 5.
During sampling, the piezometric level of groundwater must also be measured.
After a monitoring period of at least 5 years, if the analysis of the groundwater samples collected during that period has not revealed the presence of any substance referred to in paragraph 2 of section 5, the sampling frequency may be reduced to 1 sampling per year. The reduction in the sampling frequency applies as long as the analysis of groundwater samples shows that the conditions for the reduction are satisfied.
O.C. 216-2003, s. 7.
8. The analysis of groundwater samples collected pursuant to section 7 must be made by a laboratory accredited by the Minister under section 118.6 of the Environment Quality Act (chapter Q-2).
If the analysis of a sample shows that a limit value in Schedule V has been exceeded, mention to that effect must be made in the analysis report and the Minister must be informed of the excess as soon as possible.
The analysis reports produced by the laboratories must be kept for at least 5 years after the date on which they were produced.
O.C. 216-2003, s. 8.
9. The analysis reports made pursuant to section 8 in the course of a year must be transmitted to the Minister at the latest on 1 February of the following year.
An attestation stating that the samples were collected in accordance with generally accepted standards and practices and the requirements of this Regulation must also be transmitted to the Minister with the reports.

O.C. 216-2003, s. 10; I.N. 2019-12-01; O.C. 871-2020, s. 6.
11. In the case provided for in the second paragraph of section 4, the person carrying on the industrial or commercial activity must transmit to the Minister, before the expiry of the sixth month referred to in that section, a groundwater monitoring program and the opinion of a professional in conformity with the provisions of section 21 of the Regulation respecting the regulatory scheme applying to activities on the basis of their environmental impact (chapter Q-2, r. 17.1), unless, during that period, the person shows to the Minister that the groundwater monitoring requirements under the third paragraph of section 4 have been satisfied.

12. (Obsolete).
O.C. 216-2003, s. 12.
13. Any groundwater monitoring program transmitted for the purposes of section 22 of the Regulation respecting the regulatory scheme applying to activities on the basis of their environmental impact (chapter Q-2, r. 17.1) must be reviewed and updated every 5 years, in particular to take into account changes authorized by the third paragraph of section 7 or that may have occurred with regard to the land’s hydrogeological conditions, the substances referred to in paragraph 2 of section 5, the points of emission of those substances or the monitoring well system.
The reviewed and updated program must be sent to the Minister not later than 30 days after the expiry of each 5-year period.
O.C. 216-2003, s. 13; O.C. 871-2020, s. 8.
