Section 288.412 - Liner system and leachate control plan

Universal Citation: 25 PA Code § 288.412

Current through Register Vol. 54, No. 52, December 28, 2024

(a) The application shall contain plans, drawings, cross sections and specifications for a liner system to demonstrate compliance with §§ 288.431-288.440 (relating to additional operating requirements-liner system), including the following:

(1) The design of the liner system, including thickness and characteristics of the subbase, the thickness and characteristics of the leachate detection zone, the design for the leachate monitoring system in the leachate detection zone, the nature and thickness of the liner material, the thickness and characteristics of the protective cover and leachate collection zone, and the design for the leachate collection system in the collection zone.

(2) A plan for installing the liner system.

(b) The application shall include a quality assurance and quality control plan for the construction and installation of the liner system. The plan shall include the following:

(1) A description of the testing procedures and construction methods proposed to be implemented during construction of the liner system.

(2) A description of the manner in which the protective cover and liner system will be maintained and protected in unfilled portions of the disposal area prior to and during placement of the initial lift of solid waste.

(3) A description of the manner in which the protective cover and liner system will be protected from weather prior to and during placement of the initial lift of solid waste.

(4) A description of the qualifications of the quality assurance and quality control personnel, presented in terms of experience and training necessary to implement the plan.

(5) A sampling plan for every component of the liner system, including sample size, methods for determining sample locations, sampling frequency, acceptance and rejection criteria, and methods for ensuring that corrective measures are implemented as soon as possible.

(6) A plan for documenting compliance with the quality assurance and quality control plan.

(c) The application shall demonstrate that leachate will not adversely affect the physical or chemical characteristics of the proposed liner system, or inhibit the liner's ability to restrict the flow of solid waste, solid waste constituents or leachate, based on EPA or ASTM guidelines approved by the Department.

(d) The application shall include a complete description of the physical, chemical, mechanical and thermal properties for the proposed primary and secondary liners, based on ASTM methods when appropriate. Except to the extent that the Department waives in writing one or more of the following for nonsynthetic secondary liners, these properties include:

(1) Thickness.

(2) Tensile strength at yield.

(3) Elongation at yield.

(4) Elongation at break.

(5) Density.

(6) Tear resistance.

(7) Carbon black content.

(8) Puncture resistance.

(9) Seam strength-% of liner strength.

(10) Ultraviolet light resistance.

(11) Carbon black dispersion.

(12) Permeability.

(13) Liner friction.

(14) Stress crack resistance.

(15) Oxidative induction time.

(16) Chemical compatibility.

(17) Percent recycled materials.
