Agency Review of Contaminant Transport Models
Section 813
Section 813.111 Agency
Review of Contaminant Transport Models
a) At the request of any person, consistent with any resource
limitations, the Agency may review a groundwater contaminant transport (GCT)
model for acceptance. The person shall demonstrate that the model meets the
minimum requirements of 35 Ill. Adm. Code 811.317(c)(1), (c)(2) and (c)(3).
b) The Agency may designate GCT models as acceptable for use by
the applicant for a groundwater impact assessment. Such Agency designations
shall be accompanied by limitations or conditions under which the model can or
cannot be used. The applicant shall be relieved from demonstrating compliance
with 35 Ill. Adm. Code 811.317(c)(1), (c)(2) and (c)(3) in a permit application
if a model accepted by the Agency has been used.
c) An applicant using a model accepted by the Agency shall submit
documentation in a permit application showing that the model used in the
groundwater impact assessment was the same model previously reviewed and
accepted by the Agency and shall demonstrate that the model is acceptable for
use in the site specific hydrogeology of the proposed facility.
d) The requirements of this Section shall in no way require an
applicant to utilize a model accepted by the Agency. If a model is utilized
that has not been reviewed and accepted by the Agency then the applicant shall
include in the permit application all of the documentation necessary to
demonstrate compliance with 35 Ill. Adm. Code 811.317(c)(1), (c)(2), and
(c)(3).
