LAC 33:VII.801. General Facility Geology

A. The following standards regarding facility geology are applicable to all Type I, Type I-A, Type II, Type II-A, and Type III facilities. 1. The subsurface soils and groundwater conditions at facilities shall be characterized by a geologist, or a professional engineer licensed in the state of Louisiana with expertise in geotechnical engineering and hydrogeology. Both field boring logs and laboratory results shall be included as part of the permit application. 2. Except as provided in Paragraph A.3 of this Section, facilities shall have natural soils of low permeability for the area occupied by the solid waste facility, including vehicle parking and turnaround areas, that shall provide a barrier to prevent any penetration of surface spills into groundwater aquifers underlying the area or to an underlying sand or other permeable stratum that would provide a conduit to such aquifers. 3. A design for surfacing natural soils that do not meet the requirement in Paragraph A.2 of this Section shall be prepared and installed under the supervision of a professional engineer, licensed in the state of Louisiana, with expertise in geotechnical engineering and hydrogeology. Written certification by the engineer that the surface satisfies the requirements of Paragraph A.2 of this Section shall be provided.
