FUTURE WORK PROGRAM 6D has two new work items on their work plan at this time. -2-

3 Annex- I see attached. This annex provides the Requirements for Extended Hydrostatic Shell Test duration and Records Retention for Valves in Jurisdictional Pipeline Systems. This is an informative Annex and can be requested by the pipeline owner or operator to be performed in additional to the standard API 6D pressure testing activities. The 6D ballot was closed ballot was closed in November Negative votes. A TG meeting was held January 19 th, members of the 6DTG along (2) of voter who cast negative ballot. After lengthy discussion and contact the negative commenter s the entire 6D TG member it was agreed to draw the negative vote and re-ballot the annex-i as modified. Ballot # 2243 has been issue for a 6 week ballot. Annex J This annex provides for Quality Specification Level (QSL) for pipeline valves. The three (3) QSL address extended hydrostatic/pneumatic testing, NDE on selected components and required documentation to be provided. As special TG was formed from members of the 6D TG to work on this issue. 1 st meeting was held June 2010 to develop the 1 st draft and the final meeting was held January 20 th, 2011 to finalize the Annex. The 6D TG has recommended that the attached DRAFT Annex J be issued for formal ballot. 6. FUTURE MEETINGS DATES Next meeting planned for 6D TG will be in early April 2011 to review API RP6DR and API 6FA. Additionally we will hold a 6DTG meeting during the Summer Standards conference in San Francisco, Ca. June 29 th, RESOURCE NEEDS No resource needs at this time. -3-
