32 Ill. Adm. Code 351.150
Agreement with Well Owner or Operator
Section 351.150 Agreement with Well Owner or Operator
a) A
licensee may perform well logging with a sealed source only after the licensee
has a written agreement with the employing well owner or operator. This written
agreement shall identify who will meet the following requirements:
1) If a
sealed source becomes lodged in the well, a reasonable effort will be made to
recover it.
2) A
person may not attempt to recover a sealed source in a manner which, in the
licensee's opinion, could result in its rupture.
3) Radiation monitoring
required in Section 351.690(a).
4) If the
environment, any equipment, or personnel are contaminated with licensed
material, they must be decontaminated before release from the site or release
for unrestricted use.
5) If the
sealed source is classified as irretrievable after reasonable efforts at
recovery have been expended, the following requirements shall be implemented
within 30 days:
A)
Each irretrievable well logging source shall be immobilized and sealed
in place with a cement plug;
B)
A means to prevent inadvertent intrusion on the source shall be
established unless the source is not accessible to any subsequent drilling
operations; and
C)
A permanent identification plaque, constructed of long-lasting material
such as stainless steel, brass, bronze, or monel, shall be mounted at the
surface of the well unless the mounting of the plaque is not practical. The
size of the plaque must be at least 17 cm (7 inches) square and 3 mm (⅛ inch)
thick. The plaque shall contain:
i) The word "CAUTION";
ii) The
radiation symbol (the color requirement in 32 Ill. Adm. Code 340.910(a) need
not be met);
iii) The date the source was
abandoned;
iv) The
name of the well owner or well operator, as appropriate;
v) The
well name and well identification number or other designation;
vi) An
identification of the sealed source by radionuclide and quantity;
vii) The
depth of the source and depth to the top of the plug; and
viii) An
appropriate warning, such as, "DO NOT RE-ENTER THIS WELL."
b) The
licensee shall retain a copy of the written agreement for 3 years after the
completion of the well logging operation.
c) A
licensee may request Agency approval, on a case-by-case basis, of proposed
procedures to abandon an irretrievable well logging source in a manner not
otherwise authorized in subsection (a)(5).
d) A
written agreement between the licensee and the well owner or operator is not
required if the licensee and the well owner or operator are part of the same
corporate structure or otherwise similarly affiliated. However, the licensee
shall still meet the requirements in subsections (a)(1) through (a)(5).
