Conn. Agencies Regs. § 19-24-14 - Disposal into ground, water or air

(a) Any person may apply to the department for approval of proposed procedures to dispose radioactive materials into the ground, water and air environment in a manner not otherwise authorized in sections 19-24-1 to 19-24-14, inclusive. Each application should include a description of the radioactive material or materials involved, including the quantities and kinds of such material and the levels of radioactivity involved and the proposed manner and conditions of disposal. The application should also include an analysis and evaluation of pertinent information as to the nature of the environment, including topographical, geological, meteorological and hydrological characteristics; usage of ground and surface waters in the general area, the nature and location of other potentially affected facilities and procedures to be observed to minimize the risk of unexpected or hazardous exposures.

(b)

(1) No owner of an installation or mobile source shall possess, use or transfer radioactive material in such a manner as to release into the air or bodies of water outside an installation any concentration of radioactive material in excess of the limits specified in Appendix B, Table II, 10 CFR 20. For the purposes of this subdivision, concentrations may be averaged over periods not greater than one year.

(2) Determinations as to the concentrations of radioactive material shall be made with respect to the point where such material leaves the control of the owner. Where the radioactive material is discharged through a stack, tube, pipe or similar conduit, the determinations may be made with respect to the point where the material leaves such conduit.

(c) No owner of an installation or mobile source shall discharge radioactive materials into a sanitary sewage system unless:

(1) It is readily soluble or dispersible in water;

(2) The quantity of radioactive material released into the system by the owner in any one day does not exceed the larger of the quantities specified in subparagraphs (A) and (B) as follows:

(A) The quantity which if diluted by the average daily quantity of sewage released into the sewer from the installation or mobile source, will result in an average concentration equal to the limits specified in Appendix B, Table 1, Column 2, 10 CFR 20.

(B) Ten times the quantity of such material specified in Appendix C 10 CFR 20.

(3) The quantity of any radioactive material released by the owner of an installation or mobile source in any one month if diluted by the average monthly quantity of water released will not result in an average concentration exceeding the limits specified in Appendix B, Table 1, Column 2, 10 CFR 20.

(4) The gross quantity of radioactive material released into the sewerage system does not exceed one curie per year or other limits as may be specified in 10 CFR 20. Discharge of excreta from individuals undergoing medical diagnosis or therapy with radioactive material shall be exempt from the limitations contained in this subsection.

(d) No owner of an installation or mobile source shall dispose of radioactive material by dumping or by burial unless:

(1) The total quantity of radioactive material or materials buried in any one location does not exceed at the time of burial one thousand times the amounts specified in Appendix C, 10 CFR 20.

(2) Burial is at a minimum depth of four feet.

(3) Successive burials are separated by distances of at least six feet and not more than twelve burials are made in any year, and

(4) The area is approved by the department for burial of radioactive materials.

(e) No owner of any installation or mobile source shall treat or dispose of radioactive material by incineration except in accordance with plans and procedures specifically approved by the department.

(f) Each owner of an installation or mobile source shall maintain records of disposal of waste radioactive material. Such records shall be available for review by the department's representatives upon request.
