RULE ANALYSIS

Purpose of the rule or reason for the change:

The Nuclear Regulatory Commission (NRC) has revised Title 10 Code of Federal Regulations (10 CFR). NRC notified the Utah Division of Radiation Control (DRC) that the revised regulations need to be adopted by Agreement States no later than 11/14/2014. All Agreement States are required to maintain rules compatible with NRC regulations. The NRC revised the definitions of "Commencement of Construction" and "Construction". The Board proposes to revise the existing rules by incorporating the federal definitions found in 10 CFR Parts 30, 36, 40, 70, and 150.

Summary of the rule or change:

The rule will be amended by adding two definitions to Section R313-12-3. They will be listed in alphabetical order with the other definitions in that section.

State statutory or constitutional authorization for this rule:

• Section 19-3-104

Anticipated cost or savings to:

the state budget:

The NRC performed a regulatory analysis of this amendment and determined that the rule change does not impose any new burden or reporting requirements on a licensee, the NRC, or an Agreement State. See 76 FR 56961.

local governments:

The NRC performed a regulatory analysis of this amendment and determined that the rule change does not impose any new burden or reporting requirements on the licensee including a local government that may have a radioactive material license. See 76 FR 56961.

small businesses:

The NRC performed a regulatory analysis of this amendment and determined that the rule change does not impose any new burden or reporting requirements on a licensee that may also be a "small business". See 76 FR 56961.

persons other than small businesses, businesses, or local governmental entities:

The NRC performed a regulatory analysis of this amendment and determined that the rule change does not impose any new burden or reporting requirements on a licensee. See 76 FR 56961.

Compliance costs for affected persons:

The NRC performed a regulatory analysis of this amendment and determined that the rule change does not impose any new compliance burdens on licensees. See 76 FR 56961.

Comments by the department head on the fiscal impact the rule may have on businesses:

Businesses with a radioactive material license will not see a fiscal impact due to the proposed changes to Rule R313-12-3. The proposed changes do not add or remove significant requirements that affect the Radiation Control Program or the Utah Radiation Control Board.

"Working level" (WL), means any combination of short-lived radon daughters in one liter of air that will result in the ultimate emission of 1.3 x 10⁵ MeV of potential alpha particle energy. The short-lived radon daughters are, for radon-222: polonium-218, lead-214, bismuth-214, and polonium-214; and for radon 220: polonium-216, lead-212, bismuth-212, and polonium-212.
