63. The operator of an engineered landfill must, at the frequency indicated below, take or have a sample taken of the leachate or water collected by each collection system in the landfill and in resurgent water within the groundwater monitoring perimeter established under section 65, and have the samples analyzed(1) at least once a year, for the purpose of measuring the parameters or substances referred to in sections 53, 57 and 66;
(2) at least 3 times a year, in the spring, summer and fall, if the leachate or water is not conveyed to a treatment system, for the purpose of measuring the parameters or substances listed in section 53; or
(3) at least once a month, if the leachate or water is conveyed to a treatment facility established and operated pursuant to an authorization issued under the Environment Quality Act (chapter Q-2), for the purpose of measuring the parameters or substances referred to in section 53, except fecal coliforms.
The leachate and water to be sampled pursuant to the first paragraph must be sampled before being discharged into the environment or, if applicable, before being treated or discharged towards a treatment facility. For the purposes of this section, there is a discharge of surface water into the environment if the water flows out of a buffer zone established under section 18.
If the surface water does not comply with the limit values listed in section 53 before flowing into the buffer zone established under section 18, the water must also be sampled and analyzed as provided in subparagraph 2 of the first paragraph before entering the buffer zone.
The operator must also take or have a weekly sample taken of the discharges into the environment from every leachate or water treatment system in the landfill, other than surface water sediment basins, and have the samples analyzed to measure the parameters or substances listed in section 53.
Each of the samples must be a single sample (grab sample). In the case of resurgent water, the sampling must be carried out at the resurgence point.
The flow of the leachate collected by the collection systems prescribed by sections 25 and 26 and the flow of the discharges from the treatment system in the landfill must be separately and continuously measured and the results recorded.
