Minutes and Discussion

Welcome - Roll Call

(Reid) – Documents that were requested to be placed on the Subpart W website on the last call have been completed. The list included:

-April 26, 2007 Notice of Intent to Sue -Civil Suit filed against EPA -November 3, 2009 letter from DOJ establishi ng effective date of settlement agreement -Procedures for fabricating the Method 115 flux equipment -Quality Assurance Project Plan -EPA procedures for determining confidential business information

-Contract EP-D-05-002

The contract listed above expired on March 26, 2010, but has been repl aced by contract EP-D10-42, which became effective in March 2010. This document is the current contract between
EPA Office of Radiation and Indoor Air and S.Cohen and Associates for technical support work to EPA, and has also been placed on the website.

The contract for this period ta sks the contractor with severa l items related to Subpart W:Risk Assessment Model

. The final 1989 EIS used AIRDOS to calculate dose and risk to the public. The contractor will review the appropriate ness of using AIRDOS to calculate individual and population dose and risk, and provide a r ecommendation on the best model for use in presenting findings on individual an d populational dose and risk.

Detailed Risk Estimates

. The contractor will develop detail ed risk estimates for each source of emission from the management of uranium byproduc t materials from the processing of uranium ores. These estimates were presented on a fac ility-by-facility basis in the 1989 EIS, and they
will be conducted in the same format for this anal ysis. In addition to existing facilities, two or three representative faci lities will also be generated that wi ll be used to approximate conditions of new facilities in different geographic locatio ns. This will be done to accommodate the recognition that several new proce ssing facilities are expe cted to apply for licenses in the near

future.

Economic Impact Analysis. The contractor will contribute to analyzing the economic impacts of the Subpart W regulation, and contribute to asse ssing the distribution of costs and benefits among various segments of the population, with a particular focus on disadvantages and vulnerable groups.

Background Information Document. The contractor will also begin draf ting chapters for a background information document. Some topics th at need to be addressed in the document include; Characterization of the problem being addr essed, data and scientific analyses needed to make the decision, historical background, risk assessment.

(John Hamrick) For production of the risk assess ments, EPA should take advantage of the public health assessment produced by ATSDR at the Cotter mill.

(Travis Stills) – Settlement agreement letter and spirit contemplated a much broader and deeper set of documents on the website, similar to items that would be requested under a FOIA request. Reid explained that the website is not as comple te as a rulemaking docket, and asked what else
Travis would like to see on the webs ite. Travis stated that the Plaintiffs would like to see all non-privileged documents while preparing S ubpart W, and documents for ongoing work.

Doug Chambers (SENES): will his radon data be in cluded on the website? Reid says that we
will look at a national and international basis.

• Travis would like the presentation to be on the Subpart W website.

• Reid will put them on the Subpart W website (also publicly available NMA and NRC website). Katie Sweeney said that it’s okay.

(Reid) Public Meeting in Utah. Last meeting in CCAT/EPA Settlement Agreement 5/24/10; 6pm-8pm, White Mesa Community Center (Ute)

• EPA presentation with plenty time for discussion

• (S. Fields) Will there be an opportunity for individual/group to also present at this meeting? Reid. If one group allowed, then all groups allowed (including industry)(Reid) Options for various monitoring techniques

• Looking at whether flux rate is s till the best option for a standard?

• Compare Subpart W to Subparts B and H (10 mrem/yr). Looking at whether radon flux standard should be changed to an effec tive dose equivalent based on modeling. Of course some information would be input into model.

• (Oscar Paulson) Concerns over models a nd validation. What contact does EPA have with model review? (Reid) Realize shortcomings of CAP-88 code and we are making sure validation is good. We are aware of shor tcomings and hope to have them addressed.

• (J. Hamrick) Request that EPA consider th e amount of radon information collected by mills on a daily basis and where information exists use it as an input for the model

• Solicited information/thoughts from people on the call – contact Reid via E-mail.

• Travis – wants communications on this. Reid said there is none. S. Stahle – recognize
that deliberative information will not go on the website.

• (S. Fields) When does Subpart B plan on be ing reviewed? (Reid) No answer now. Decision would be made by ORIA management. No time set to date.

• (S. Cunningham) Are we looking at the possibilit y of radon testing at Subpart W facilities built after 1989. (Reid) Short an swer – yes. We will be l ooking at continuing with work practices or looking at flux standard?

• (O. Paulson) NRC looks at dose above background. Concerned about background affecting radon at mills from natural sources. Are we looking at background? (Reid) It is something we will look at. Preceden t for GW for 4 quarters of background.

• (O. Paulson) Data from Cameco from ISLs ? When will it go on the website? (Reid) Commits to have it on by next conference call (July 6 th ).
