Current through June 17, 2024
005.01 All Class V well designs shall be
  submitted to the Department for approval prior to their construction. Minimum
  setback distances outlined in this Section are for guidance; the Department
  will review each Class V well siting on a case-by-case basis.
005.02 Designs for domestic wastewater
  disposal wells as defined in Chapter 2,
005.17C
shall
  be submitted by a professional engineer and designed, sited and constructed
  according to Title 124 -
Rules and Regulations for the Design,
  Operation, and Maintenance of On-Site Wastewater Treatment
  Systems
. Minimum setback distances are outlined in Table 17.1
  below; a more detailed table of setback distances can be found in Title 124,
  Chapter 5, Table 5.1.

005.03 All
  Class V wells, with the exception of those specified in
005.02
of this Chapter, that are constructed above and
  do not inject into the uppermost aquifer shall be designed, sited and
  constructed using the following criteria:
005.03A Wells must be cased with a material
  that will have the integrity to keep the formation from collapsing for the life
  of the well and be compatible with the fluid to be injected;
005.03B Wells that have the potential to
  accept fluids from areas that may generate waste from vehicles (i.e. parking
  lots) must be equipped with an integral oil/water separator.
005.03C The casing may be open at the bottom
  or perforated to allow for the injected fluids to be released;
005.03D The surface completion must
  incorporate a grate or perforated cover to prevent endangerment to persons
  and/or livestock. The examples illustrated below are only a few variations,
  other designs may be acceptable;

005.03E The surface completion must be
  designed to accept only the fluids for which the well is authorized or
  permitted to accept;
005.03F The
  total depth of the well must not exceed 20 feet and maintain a minimum
  separation distance of four (4) feet between the bottom of the casing and the
  static water level, the seasonal high ground water and/or any confining bed.
  This four (4) feet separation distance may need to be increased based on the
  characteristics of the injection fluids;
005.03G All Class V wells that are
  constructed above and do not inject into the uppermost aquifer with exception
  of those specified in
005.02
of this Chapter must be
  sited using the minimum setback distances outlined in Table 17.2 below:
