310 CMR, § 30.645
The provisions of 310 CMR 30.645 apply only to liners installed after October 15, 1983. Submitted with the license application shall be a demonstration that the waste(s) and leachate that may be in contact with the liners will be compatible with the liner materials to be used. The license applicant shall persuade the Department that the wastes will not have any detrimental effect (e.g., cause cracks, swelling, decrease in mechanical strength, change in chemical properties or increase in permeability) on the liner materials used to prevent leakage into or out of the space between the liners. This demonstration shall be made by conducting field tests or laboratory tests which shall be acceptable to the Department. All such testing shall be fully documented and submitted with the license application.
