AUTHORITY: Implementing and authorized by Sections 13.6 and 27 of the Environmental
Protection Act [415 ILCS 5/13.6 and 27].
SOURCE: Adopted at 32 Ill. Reg. 7789, effective May 2, 2008.
SUBPART A: GENERAL PROVISIONS
Section 1010.100
Purpose
This Part prescribes standards for detecting and reporting unpermitted releases of radionuclides
from nuclear power plants pursuant to Section 13.6 of the Illinois Environmental Protection Act
[415 ILCS 5/13.6].
Section 1010.102
Applicability
This Part applies to licensees of nuclear power plants that are required under Section 13.6 of the
Act to report an unpermitted release of a radionuclide.

Section 1010.104
Scope
This Part sets forth the procedures licensees of nuclear power plants must follow to satisfy their
obligation under Section 13.6 of the Act to report unpermitted releases of radionuclides to the
Agency and to IEMA. This Part addresses only the reporting of unpermitted releases of
radionuclides required under Section 13.6 of the Act. The requirements of this Part are
independent of, and do not replace or supersede, any other reporting requirements in State or
federal law or regulation. This Part does not prevent or preclude licensees from reporting
releases of radionuclides that are not required to be reported under Section 13.6 of the Act.
Section 1010.106
Definitions
Except as stated in this Section, or unless a different meaning of a word or term is clear from the
context, the definition of words or terms in this Part shall be the same as that applied to the same
words or terms in the Illinois Environmental Protection Act.
“Act” means the Illinois Environmental Protection Act [415 ILCS 5].
“Agency” means the Illinois Environmental Protection Agency.
“Curie” or “Ci” means the quantity of radioactive material producing 37 billion nuclear
transformations per second.
"Groundwater" means underground water that occurs within the saturated zone and
geologic materials where the fluid pressure in the pore space is equal to or greater than
atmospheric pressure
. [415 ILCS 5/3.64]
“IEMA” means the Illinois Emergency Management Agency.
“L” means liter.
“Licensee” means the holder of a license issued for a nuclear power plant under chapter I
of title 10 of the Code of Federal Regulations.
“Licensee controlled area” means the land or property that is owned, leased, or otherwise
controlled by the licensee.
“Picocurie” or “pCi” means the quantity of radioactive material producing 2.22 nuclear
transformations per minute. One pCi is one trillionth (10
-12
) of one curie.
"Person" is any individual, partnership, co-partnership, firm, company, limited liability
company, corporation, association, joint stock company, trust, estate, political

 
subdivision, State agency, or any other legal entity, or their legal representative, agent,
or assigns.
[415 ILCS 5/3.315]
“Station generated liquids” means liquids used in, or as a part of, the power generation
process at a nuclear power plant and that contain, or potentially could contain, radionuclides.
“Surface water” means all water that is open to the atmosphere and subject to surface runoff.
“Unpermitted release of a radionuclide” means any spilling, leaking, emitting,
discharging, escaping, leaching, or disposing of a radionuclide into groundwater,
surface water, or soil that is not permitted under State or federal law or regulation.
[415
ILCS 5/13.6(c)]. “Unpermitted release of a radionuclide” does not include the discharge
of a radionuclide from a point source at a designated process water or cooling water
outfall identified in the nuclear power plant’s National Pollutant Discharge Elimination
System permit, provided the discharge is authorized in the nuclear power plant’s United
States Nuclear Regulatory Commission operating license.
1010.108
Severability
If any provision in this Part or its application to any person or under any circumstances is
adjudged invalid, such adjudication shall not affect the validity of this Part as a whole or of any
portion not adjudged invalid.
SUBPART B: REPORTING
Section 1010.200
Evaluation of Releases
Within 24 hours after an unpermitted release of a radionuclide from a nuclear power plant into
groundwater, surface water, or soil, the licensee must evaluate the release in accordance with this
Section to determine whether it must be reported. The evaluation cannot take into account
remedial actions taken in response to the release (i.e., the evaluation must be based on the
volumes of station generated liquids and concentrations or quantities of radionuclides released,
not on the volumes of station generated liquids and concentrations or quantities of radionuclides
remaining after the initiation or completion of response actions). If the release is required to be
reported, the licensee must report the release in accordance with Section 1010.202 of this Part.
a)
Licensees must report unpermitted releases of station generated liquids that result
in tritium concentrations of 200 pCi/L or more outside of the licensee controlled
area.
b)
Licensees must report unpermitted releases of station generated liquids that
contain tritium at quantities of 0.002 Curies or more.

Section 1010.202
Reporting of Releases
a)
Reports required under Section 1010.200 must be given within 24 hours after the
release to both the Agency and IEMA in accordance with the following:
1)
Reports to the Agency must be given by telephone and electronically. The
Agency’s telephone number for reporting environmental emergencies is 1-
217-782-3637.
2)
Reports to IEMA must be given by telephone and electronically. IEMA’s
telephone number for reporting emergencies is 1-800-782-7860, or, if
calling from outside Illinois, 1-217-782-7860.
3)
Electronic reports must be submitted on forms and in a format prescribed
by the Agency, and must be submitted to addresses prescribed by the
Agency and IEMA. The Agency shall consult with IEMA in developing
the forms and format for electronic reports required under this Section.
b)
Reports required under Section 1010.200 must include, at a minimum, the
following information using the best data available at the time of the report:
1)
