Only the regulations concerning certified verification agents (CVAs) are included. REQUIREMENTS FOR CVAs IN BOEMRE OIL AND GAS REGULATIONS Below are excerpts from 30 CFR Part 250, “Oil and Gas and Sulphur Operations in the Outer Continental Shelf.” § 250.916 What are the CVA’s primary duties during the design phase? a. The CVA must use good engineering judgment and practices in con- ducting an independent assessment of the design of the platform, major modification, or repair. The CVA must ensure that the platform, major modification, or repair is designed to withstand the environmental and functional load conditions appropriate for the intended service life at the proposed location. b. Primary duties of the CVA during the design phase include the fol- lowing: [Table 1]. c. The CVA must submit interim reports and a final report to the Regional Supervisor, and to you, during the design phase in accordance with the approved schedule required by §250.911(d). In each interim and final report the CVA must 1. Provide a summary of the material reviewed and the CVA’s findings; 2. In the final CVA report, make a recommendation that the Regional Supervisor either accept, request modifications, or reject the pro- posed design unless such a recommendation has been previously made in an interim report; 148
