SOLID WASTE PROCESSING AND DISPOSAL
Rule 1200-01-07-.04, continued)
deemed by the Commissioner to be necessary to provide a complete and accurate description of relevant subsurface conditions.
The report must include, but not necessarily be limited to, the following information:
A description of the soil sampling and analytical procedures used including, but not necessarily limited to, a characterization of the soils underlying the site providing, at a minimum:
Unified soil classifications;
The saturated hydraulic conductivities of undisturbed samples of soils underlying the site which are to be used in meeting soil buffer requirements;
The saturated hydraulic conductivity of remolded samples of soils taken from the site which are to be used in meeting liner and cover requirements; and
A description of the soil sampling and analytical procedures used;
A tabulation of water table elevations (if encountered within the limits of drillings) measured at the time borings were performed and at least two additional measurements over a period of at least one week so as to allow water elevations to stabilize. If an estimation of the seasonal high water table cannot be made utilizing this data and other existing information, then the Commissioner may require water table elevations to be collected over a period up to one year.
A boundary plat locating soil borings with accurate horizontal and vertical controls which are tied to a permanent on-site bench-mark (reference elevation may be site specific). The plat must include the boundary of the proposed fill areas;
A potentiometric map of the uppermost aquifer (if such can be determined by information obtained within the limits of drilling) based on stabilized water elevations;
A description of local ground water recharge and discharge features in the vicinity of the proposed landfill site and, if the Commissioner deems appropriate, a description of the regional ground water regime;
The locations of any springs and existing and abandoned wells within a one mile radius;
The locations of public water supply system intakes within a two mile radius; and
A narrative summary and analysis of geological and hydrological evaluations performed as they relate to the suitability of the site for a disposal facility, and addressing in particular compliance with appropriate standards of this rule.
