Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 80 - Solid Waste Management › Chapter 2 - General Provisions › Section 10 CSR 80-2.015 - Preliminary Site Investigation, Detailed Site Investigation Work-plan, and Detailed Site Investigation and Characterization Report

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This rule describes the steps required to
				  characterize the geologic and hydrologic conditions at a proposed solid waste
				  disposal area prior to submittal of a construction permit application in
				  compliance with section
				  260.205,
				  RSMo (Cum. Supp. 1996).
(1)
				On and after January 1, 1996, no applicant may apply for, or obtain, a permit
				to construct a solid waste disposal area unless the person has obtained
				geologic and hydro-logic site approval from the department. Geologic and
				hydrologic approval indicates that the site has been found to be suitable for
				development of a solid waste disposal area, provided the required plans and
				engineering reports detailing the construction and operation of the site are
				prepared and approved by the department. In order to obtain geologic and
				hydrologic site approval from the department, the following procedures must be
				followed:
(A) The potential disposal area
				construction permit applicant must obtain preliminary site approval from the
				department. The applicant shall provide the department a map that delineates
				the approximate horizontal boundaries of the proposed solid waste disposal area
				and provide the approximate elevation of the base of the proposed solid waste
				disposal area. The applicant may provide the department any other information
				pertinent to the site that may assist in the preliminary site investigation.
				The Division of Geology and
Land Survey (DGLS) Geologic Survey Program (GSP) will conduct
				  a preliminary site investigation and approve or disapprove the site for further
				  investigation within sixty (60) days of receipt of a request. Preliminary site
				  approval is provisional, as required additional investigations may reveal
				  conditions that may lead to site disapproval. Disapproval may be reviewed by
				  the DGLS division director. Preliminary site investigation requests shall be
				  submitted to the GSP on the form included in Appendix 1 which is included
				  herein. After performing a preliminary site investigation, the GSP shall make
				  one (1) of the following determinations:
1. The geologic and hydrologic conditions of
				the site are not suitable for the development of a solid waste disposal area.
A. Sites proposed for sanitary or demolition
				waste landfills known to have one (1) or more of the following geologic or
				hydrologic conditions within its boundaries are considered unsuitable for the
				development of a solid waste disposal area:
(I) Groundwater that must be pumped in order
				to keep the wastes within the proposed solid waste disposal area isolated above
				the water table;
(II) Permeable
				geologic media, including soil or bedrock with karst terrane features, faults,
				joints, fractures, or voids, that provide a pathway for the rapid migration of
				fluids from the site into the uppermost regional aquifer or the rapid migration
				of groundwater from the site to a surface water body outside of the
				site;
(III) Permeable geologic
				media, including soil or bedrock with karst terrane features, faults, joints,
				fractures, or voids, that provide a pathway for the migration of
				landfill-derived gases outside of the site;
(IV) A fault that has experienced movement
				during the Holocene epoch that is located within the boundaries of the proposed
				solid waste disposal area;
(V)
				Groundwater that cannot effectively be monitored on-site due to karst terrane
				conditions; or
(VI) The presence of
				subsurface voids or conditions that present a significant potential for
				catastrophic collapse.
