Effective Date of Rule: Thirty-one days after filing.

     Purpose: This rule revision addresses recent federal rule changes pertaining to transportation of radioactive materials. The rule improves public health by revising transportation procedures that pose the highest risk of exposure to workers and the general public, and structures the regulations to be more risk-informed and performance-based.

     Citation of Existing Rules Affected by this Order: Repealing WAC 246-231-070; amending WAC 246-231-001, 246-231-005, 246-231-010, 246-231-030, 246-231-040, 246-231-060, 246-231-080, 246-231-090, 246-231-100, 246-231-110, 246-231-120, 246-231-140, and 246-231-200.

     Statutory Authority for Adoption: RCW 70.98.050.

      Adopted under notice filed as WSR 08-03-067 on January 14, 2008.

     Changes Other than Editing from Proposed to Adopted Version: Two changes were made from the proposed to the final rule. The first change corrected a cross reference in WAC 246-231-136 from WAC 246-231-133 to WAC 246-231-040(4). The second change was to underline Table 2 in WAC 246-231-200. The code reviser's office published a note with the CR-102 filing in the Washington state register to address this error. There are no other changes.

[]

2	While the term "licensee" is used in these criteria, the requirements are applicable to whatever design, fabrication, assembly, and testing of the package is accomplished with respect to a package before the time a package approval is issued.

     (2) The quality assurance functions are:

     (a) Assuring that an appropriate quality assurance program is established and effectively executed; and

     (b) Verifying, by procedures such as checking, auditing, and inspection, that activities affecting the functions that are important to safety have been correctly performed.

     (3) The persons and organizations performing quality assurance functions must have sufficient authority and organizational freedom to:

     (a) Identify quality problems;

     (b) Initiate, recommend, or provide solutions; and

     (c) Verify implementation of solutions.

     (4) The persons and organizations performing quality assurance functions shall report to a management level that assures that the required authority and organizational freedom, including sufficient independence from cost and schedule, when opposed to safety considerations, are provided.

     (5) Because of the many variables involved, such as the number of personnel, the type of activity being performed, and the location or locations where activities are performed, the organizational structure for executing the quality assurance program may take various forms, provided that the persons and organizations assigned the quality assurance functions have the required authority and organizational freedom.

     (6) Irrespective of the organizational structure, the individual(s) assigned the responsibility for assuring effective execution of any portion of the quality assurance program, at any location where activities subject to this chapter are being performed, must have direct access to the levels of management necessary to perform this function.

     (2) The licensee, certificate holder, and applicant for a CoC, through its quality assurance program, shall provide control over activities affecting the quality of the identified materials and components to an extent consistent with their importance to safety, and as necessary to assure conformance to the approved design of each individual package used for the shipment of radioactive material. The licensee, certificate holder, and applicant for a CoC shall assure that activities affecting quality are accomplished under suitably controlled conditions. Controlled conditions include the use of appropriate equipment; suitable environmental conditions for accomplishing the activity, such as adequate cleanliness; and assurance that all prerequisites for the given activity have been satisfied. The licensee, certificate holder, and applicant for a CoC shall take into account the need for special controls, processes, test equipment, tools, and skills to attain the required quality, and the need for verification of quality by inspection and test.

     (3) The licensee, certificate holder, and applicant for a CoC shall base the requirements and procedures of its quality assurance program on the following considerations concerning the complexity and proposed use of the package and its components:

     (a) The impact of malfunction or failure of the item to safety;

     (b) The design and fabrication complexity or uniqueness of the item;

     (c) The need for special controls and surveillance over processes and equipment;

     (d) The degree to which functional compliance can be demonstrated by inspection or test; and

     (e) The quality history and degree of standardization of the item.

     (3) In the calculations of A1 and A2 for a radionuclide not in this section, Table A-1, a single radioactive decay chain, in which radionuclides are present in their naturally occurring proportions, and in which no daughter ((nuclide)) radionuclide has a half-life either longer than ten days, or longer than that of the parent ((nuclide)) radionuclide, shall be considered as a single radionuclide, and the activity to be taken into account, and the A1 or A2 value to be applied shall be those corresponding to the parent ((nuclide)) radionuclide of that chain. In the case of radioactive decay chains in which any daughter ((nuclide)) radionuclide has a half-life either longer than ten days, or greater than that of the parent ((nuclide)) radionuclide, the parent and those daughter ((nuclides)) radionuclides shall be considered as mixtures of different ((nuclides)) radionuclides.

     ((IV.)) (4) For mixtures of radionuclides whose identities and respective activities are known, the following conditions apply:

     (a) For special form radioactive material, the maximum quantity transported in a Type A package:

Where B(i) is the activity of radionuclide I, and A1(i) is the A1 value for radionuclide I.

     (b) For normal form radioactive material, the maximum quantity transported in a Type A package:

Where B(i) is the activity of radionuclide I and ((A1(i) and)) A2(i) ((are)) is the ((A1 and)) A2 value((s)) for radionuclide I((, respectively)).

     (c) Alternatively, ((an)) the A1 value for mixtures of special form material may be determined as follows:

Where f(i) is the fraction of activity ((of nuclide)) for radionuclide I in the mixture and A1(i) is the appropriate A1 value for ((nuclide)) radionuclide I.

     ((An)) (d) Alternatively, the A2 value for mixtures of normal form material may be determined as follows:

Where f(i) is the fraction of activity ((of nuclide)) for radionuclide I in the mixture and A2(i) is the appropriate A2 value for ((nuclide)) radionuclide I.

     ((V.)) (e) The exempt activity concentration for mixtures of nuclides may be determined as follows:

Where f(i) is the fraction of activity concentration of radionuclide I in the mixture, and A is the activity concentration f material containing radionuclide I.

     (f) The activity limit for an exempt consignment for mixtures of radionuclides may be determined as follows:

Where f(i) is the fraction of activity of radionuclide I in the mixture, and A is the activity limit for exempt consignments for radionuclide I.

     (5) When the identity of each radionuclide is known, but the individual activities of some of the radionuclides are not known, the radionuclides may be grouped and the lowest A1 or A2 value, as appropriate, for the radionuclides in each group may be used in applying the formulas in ((paragraph IV)) subsection (4) of this section. Groups may be based on the total alpha activity and the total beta/gamma activity when these are known, using the lowest A1 or A2 values for the alpha emitters and beta/gamma emitters.
