Wisconsin Administrative Code › Department of Natural Resources › NR 700-799 - Environmental Protection - Investigation and Remediation of Environmental Contamination › Chapter NR 716 - Site Investigations › Section NR 716.09 - Site investigation work plan

Current through June 24, 2024
(1) GENERAL. Unless
				otherwise directed by the department, in cases where a site investigation is
				required under s.
				NR
				716.05, responsible parties shall submit a work plan
				to the department within 60 days of receiving notification that a site
				investigation is required, describing the intended scope and conduct of a field
				investigation. One paper copy and one electronic copy of the plan shall be
				submitted to the department, unless otherwise directed by the department, in
				accordance with s.
				NR
				700.11(3g).
Note:
Guidance for Electronic Submittals for
				  the GIS Registry outlines how electronic copies should be submitted in the
				  Adobe Portable Document Format (PDF) on optical disk media. This guidance can
				  be accessed at
http://dnr.wi.gov/files/PDF/pubs/rr/RR690.pdf
.
(2)CONTENTS. The work plan shall
				include all of the following information, unless otherwise directed by the
				department:
(a) Site name, address, and
				location by quarter-quarter section, township, range and county, and the
				location information specified in s.
				NR 716.15(5)
				(d).
Note:
Section
				  NR 716.15(5)
				  (d) requires submittal of Wisconsin
				  Transverse Mercator (WTM) coordinates.
(b) Name and address of the responsible party
				or parties, and name and address of all consultants or contractors involved in
				the response action.
(c) Site
				location map, consisting of the applicable portion of a 1:24,000-scale
				topographic quadrangle published by the United States geological survey with
				the name of the quadrangle indicated, and a site layout map to approximate
				scale depicting the layout of buildings, roads, discharge location and other
				relevant features of the site.
(d)
				Information gathered during scoping of the project, including the applicable
				items in s.
				NR
				716.07.
(e) Basic information on the physiographical
				and geological setting of the site necessary to choose sampling methods and
				locations, including:
1. The existing
				topography, including prominent topographic features.
2. The surface water drainage patterns and
				significant hydrologic features, such as surface waters, springs, surface water
				drainage basins, divides, wetlands and whether the site lies within a
				floodplain or floodway.
3. Texture
				and classification of surficial soils.
4. General nature and distribution of
				geologic materials, including the thickness and type of unconsolidated
				materials and the type and nature of bedrock.
5. General hydrogeologic
				information.
6. Potential hazardous
				substance migration pathways.
(f) Sampling and analysis strategy to be used
				during the field investigation, including:
1.
				A description of the investigative techniques to be used to characterize the
				site or facility.
2. Identification
				on a site layout map of the locations, both planimetric and vertical, from
				which samples of environmental media will be obtained. Where locations cannot
				be specified in advance, the work plan shall include a description of the
				strategy to be used for determining these locations in the field.
3. A description of sampling methods to be
				used, including methods for collecting, preserving and delivering samples, and
				leak detection methods.
4. An
				itemization of the parameters for which samples will be analyzed, as well as
				the analytical methods to be used and their method detection limits.
5. A description of quality control and
				quality assurance procedures to be used per sampling method, including the
				items specified in s.
				NR
				716.13.
6.
				A description of the procedures to be used to prevent cross-contamination among
				samples.
7. A description of the
				type of investigative wastes that will be generated during the site
				investigation and how they will be collected, stored, transported and treated
				or disposed of.
8. A discussion of
				how the sampling and analysis results will be related to results of any
				previous investigations at the site or facility, and how the results will be
				used to determine the degree and extent of the contamination and the selection
				of a remedial action option including, where appropriate, natural
				attenuation.
(g) A
				description of other procedures to be used for site management, including
				erosion control and repair of structural, soil, or ground
				disturbance.
(h) A schedule for
				conducting the field investigation and reporting the results to the
				department.
