Ill. Admin. Code tit. 77, § 905.140 - Holding Tanks
a) General.
Holding tanks are approved for private sewage disposal only under the following
circumstances:
1) Where site conditions, such
as type of soil, water table, terrain, lack of size or other conditions, are
not suitable to achieve compliance with this Part for installing a private
sewage disposal system.
2) As a
temporary measure while awaiting the availability of a municipal sewer
extension. This temporary condition shall not exceed one year in
length.
3) As a sanitary dumping
station to receive the discharge from holding facilities on recreational
vehicles.
4) To receive the
discharge from fixtures or drains that receive waste products such as
automotive grease, oils, solvents and chemicals that are not allowed to be
discharged into a private sewage disposal system. These waste products shall be
handled according to rules for the disposal of oil, gas and grease promulgated
under the Environmental Protection Act, or according to 35 Ill. Adm. Code
Subtitle G, or shall be taken to an oil and gas reclamation center. (Also see
the Illinois Plumbing Code.) Holding tanks to be used as described in this
Section shall be Underwriters Laboratories, Inc. certified, constructed of
materials approved for gas and oil interceptors as specified in 77 Ill. Adm.
Code 890.520, and properly anchored
to prevent flotation.
b)
Approval. Approval for holding tanks shall be obtained in writing from the
Department or local authority prior to installation. Approval shall be based on
compliance with this Section.
c)
Construction and Location. Holding tanks shall be designed and constructed in
compliance with Section
905.40 (Septic Tanks), except
that the outlet shall be permanently sealed. Holding tanks shall be located to
comply with the requirements for septic tanks and aerobic treatment plants (see
Appendix A, Illustration D).
d)
Conversion to Conventional Private Sewage Disposal Systems. Holding tanks
installed under subsection (a)(2) shall be converted to a conventional private
sewage disposal system within one year after the original installation if a
municipal sewer has not been extended to serve the property.
