Section 43.51 - Specific Guidance for the Application of Particular Conditions(1)General. 310 CMR 43.51 provides guidance on the application of particular conditions as part of the preparation of the Report Identifying Possible Locations.(2)Potential Productive Aquifer- 310 CMR 43.20(1)(c) The Board shall not consider for siting locations within the Zone II or Zone III, as applicable, of future community water systems which have received Department approval as a new source or have submitted the appropriate documentation to the Department for a new source approval in accordance with Department guidelines.(3)Depth to Water Table- 310 CMR 43.20(1)(g). Depth to the water table may be inferred by considering, but not limited to, any of the following: frequency and distribution of wetlands, location of surface water bodies, elevation and topography, soil types and relevant well drillers logs so long as:(a) the rationale for the method of inference is developed by responsible professionals experienced in the hydrogeology and geology of Massachusetts; and(b) the rationale is explained in the report.(4)Distance from Surface Water Supplies- 310 CMR 43.21(1)(a) and (b). Upgradient and down-gradient directions for groundwater flow may be inferred from surface topography in the absence of readily available subsurface data.(5)Site Size- 310 CMR 43.25. In applying this condition, consideration should be taken of the substantial variability in natural environments and geologic conditions. The possible locations identified in the subject report must be large enough to allow the evaluation of a range of candidate sites during the subsequent phase of site investigation, including the preparation of the Candidate Site Identification Report. Consideration should also be given to the minimum land area determined by the Board to be required for suitable facilities.
