N.H. Admin. Code § He-P 4024.08

Current through Register No. 50, December 12, 2024

Section He-P 4024.08 - Completion of Decommissioning

(a) The licensee shall complete decommissioning of the facility or site as soon as practicable but no later than 24 months following the initiation of decommissioning, unless an alternate schedule addressing the factors in He-P 4024.08(c) is requested with written justification and approved by the DHHS/RHS.

(b) When decommissioning involves the entire site, the licensee shall request license termination upon completion of decommissioning activities.

(c) For decommissioning plans calling for completion of decommissioning later than 24 months after plan approval, the plan shall include a justification for the decommissioning schedule warranted by consideration of the following:

(1) Whether it is technically feasible to complete decommissioning within the allotted 24-month period;

(2) Whether sufficient waste disposal capacity is available to allow completion of decommissioning within the allotted 24-month period;

(3) Whether a significant volume reduction in wastes requiring disposal will be achieved by allowing short-lived radionuclides to decay;

(4) Whether a significant reduction in radiation exposure to workers can be achieved by allowing short-lived radionuclides to decay; and

(5) Other site-specific factors which the DHHS/RHS considers appropriate on a case-by-case basis, including but not limited to:

a. The regulatory requirements of other government agencies, lawsuits, groundwater treatment activities, monitored natural ground-water restoration, actions that could result in more environmental harm than deferred cleanup; and

b. Other factors beyond the control of the licensee.

(d) As the final step in decommissioning, the licensee shall:

(1) Conduct a radiation survey of the premises where the licensed activities were carried out, and:

a. Submit a report of the results of this survey in (1) above, unless the licensee demonstrates that the premises are suitable for release in some other manner;

b. As appropriate:

1. Report levels of gamma radiation in units of millisieverts, or microroentgens, per hour at one meter from surfaces; and

2. Report levels of radioactivity, including alpha and beta:

(i) In units of megabecquerels, or disintegrations per minute or microcuries, per 100 square centimeters, removable and fixed, for surfaces;

(ii) In units of megabecquerels, or microcuries, per milliliter for water; and

(iii) In units of becquerels, or picocuries, per gram for solids such as soils or concrete; and

c. Specify the survey instrument(s) used and certify that each instrument is properly calibrated and tested;

(2) Certify the disposition of all licensed material including accumulated wastes, by submitting a completed Form RHP-10 containing the following:

a. Name of licensee;

b. Address of licensee;

c. Department(s) of licensee, as applicable;

d. License number of licensee;

e. Individual isotope user(s);

f. The name of the certifying official duly authorized by the licensee to certify that licensable quantities of radioactive material under the jurisdiction of the DHHS/RHS are not possessed by the licensee, and to request that the license be terminated; and

g. The dated signature of the certifying official of the licensee;

(3) Clearly indicate on the form required by (d) (2) above whether:

a. All use of radioactive materials authorized by the license has been terminated;

b. Radioactive contamination has been removed to the level outlined in He-P 4024.09 to the extent practicable;

c. No radioactive material has ever been procured or possessed by the licensee under the authorization granted by the licensee's license;

d. All radioactive material previously procured or possessed under the authorization granted by the license has been disposed of by:

1. Transfer to another licensed entity authorized to possess the material and provide the recipient entity's name, address, and the license number and radiation regulatory licensing authority;

2. Decay, survey, and disposal as non-radioactive trash; or

3. A method in compliance with the provisions of He-P 4023;

e. Radiation surveys or the equivalent as specified in He-P 4024.08(d) are attached; and

f. Additional pages containing additional information are attached;

(4) Include, as additional attached pages to the Form RHP-10, a clear and detailed description of the method of disposal of radioactive material, if the licensee disposed of radioactive material using a method other than that indicated in He-P 4024.08(d) (3) d.1. or 2. above; and

(5) Include, as additional attached pages to the form, report(s) of detailed radiation surveys required by He-P 4024.08(d) (1) .
