and Painting Activities in Public and Commercial Buildings, under TO 39, Contract EP-C-12-045

Prior to potentially entering into any arrangement with a peer reviewer, Versar has conducted a thorough evaluation to determine 

if the candidate reviewers pose a conflict of interest or an appearance of a lack of impartiality. Each candidate peer reviewer has 

provided answers to all questions of conflict of interest to date and all written information that Versar collected shall be retained 

in Versar’s files including an explanation of the suitability and rationale for including or excluding each final proposed panelist. 

In addition to the collection of written information, Versar staff have conducted Internet searches for public comments made by 

each candidate reviewer. 

With this letter, Versar concludes and certifies that all proposed peer review panelists have adequately passed the COI evaluation 

process signifying that, in Versar’s judgement, there is no significant evidence to trigger a COI finding for any of the proposed

panel members listed below. Versar shall select and enlist the services of reviewers from the list of proposed panelists below.

Through Versar’s continuing obligation to identify and report any actual or potential conflict of interest or an appearance of a 

lack of impartiality, Versar’s files will document the results of each panelist’s recertification. If any actual or potential conflict of

interest or appearance of a lack of impartiality is found, disclosure shall be made to the EPA.
