The location of the infiltration galleries or injection wells shall meet the setback requirements specified below unless it can be demonstrated that these requirements cannot be met and that operation of the infiltration galleries or injection wells at the proposed locations will not result in the migration of contaminants into previously uncontaminated areas and a contravention of groundwater standards beyond the compliance boundary. The following setbacks, in feet, shall be applicable to these systems:


wells with the exception of an approved groundwater monitoring well                                                    100

surface waters such as intermittent and perennial, perennial waterbodies, and wetlands                      100

property under separate ownership                                                                                                                  50

structures – above-ground, such as buildings, or retention walls                                                                10

structures – subsurface, such as utilities, basements, or swimming pools                                                15

water lines                                                                                                                                                             10

rock outcrops                                                                                                                                                       50

top of slope of embankments or cuts of two feet or more in vertical height                                             15

groundwater lowering ditches where the bottom of the ditch intersects the SHWT                               100
