The location of the infiltration gallery or injection well(s) must meet the setback requirements specified below unless it can be demonstrated that these requirements cannot be met, and that operation of the infiltration gallery(ies) or injection well(s) at the proposed location(s) 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) are applicable to these systems:

 

any well with the exception of an approved groundwater monitoring well                                              100

surface waters streams – intermittent and perennial, perennial waterbodies, and wetlands)                               100

any property under separate ownership                                                                                                          50

structures – above-ground (e.g. buildings, retention walls)                                                                          10

structures – subsurface (e.g. utilities, basements, swimming pools)                                                           15

any water line                                                                                                                                                       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

surface water diversions (ephemeral streams, waterways, ditches)                                                           25

subsurface groundwater lowering drainage systems                                                                                     100
