Wisconsin Administrative Code › Department of Natural Resources › NR 500-599 - Environmental Protection - Solid Waste Management › Chapter NR 516 - Landfill Construction Documentation › Section NR 516.04 - General requirements

Current through June 24, 2024
(1) REPORT PREPARATION. A report documenting
				all aspects of construction shall be prepared for the initial construction of
				the landfill; the construction of all subsequent phases or portions thereof;
				the construction of any storm water, groundwater, leachate or gas control
				structures; the implementation of remedial actions; and the closure of each
				major disposal area. Approval of a report which documents the construction of
				any portion of the base of a landfill shall be obtained from the department
				prior to initiating disposal operations in the newly established area, unless
				the department does not issue a determination within 60 days after receiving a
				complete submittal, along with the appropriate review and construction
				inspection fees specified in ch. NR 520.
(2) QUALITY ASSURANCE. Construction and
				closure of all landfills shall comply with the following:
(a) A registered professional engineer or
				qualified technician who is directly supervised by a professional engineer
				shall be continuously on-site and performing assigned quality assurance duties
				throughout the following: placement and testing of the clay component of the
				liner and cover systems, installation and testing of the geosynthetic
				components of liner and cover systems, all aspects of sump and sideslope riser
				construction or penetrations of the sidewall liner, manhole and tank
				installation, and placement of the drainage layer or cover soil above the
				geosynthetic liner. These personnel shall also be on-site to inspect the
				following activities after their completion: temporary and permanent erosion
				control measures such as ditches, fencing and sedimentation basins; subbase and
				leachate collection line undercut excavation and grading; clay liner surface
				preparation and grading, leachate, lysimeter and gas piping prior to their
				being covered with soil; piping with tanks, manholes or vaults and installation
				of instrumentation and controls; and gas extraction well heads. The department
				may require by written approval that a registered professional engineer be
				present during other critical construction activities.
(b) With respect to par. (a), substitution of
				personnel shall only occur due to substandard performance, vacations or
				uncontrollable circumstances such as injury, illness, employee termination or
				resignation. However, if necessary in order to provide experienced personnel,
				geomembrane installation quality assurance may be performed by a different
				registered professional engineer or qualified technician directly supervised by
				that registered professional engineer. In no case, however, may the personnel
				performing quality assurance for geomembrane installation be employed by the
				geomembrane manufacturer, fabricator or installer. Also, where justified by the
				size of the construction project, multiple registered professional engineers or
				qualified technicians may perform quality assurance work concurrently.
