91茄子 Comments on the PHMSA Draft Integrity Verification Process

 

Based on its interpretations, 91茄子 offers the following high-level comments on PHMSA’s IVP proposal:

  1. MAOP verification and IM should not be combined into a single process.
  2. 91茄子 fully supports extending and improving IM.
  3. A single pressure test during a pipeline’s life is an adequate basis for reconfirming an MAOP.
  4. FFS should be used as the basis for addressing previously untested pipelines and pipelines lacking adequate records.
  5. 91茄子 members will work with PHMSA to demonstrate use of ILI in lieu of hydrostatic testing.
  6. Application of FFS has the desired effect of deleting provisions of the grandfather clause that cause concern to stakeholders.
  7. PHMSA currently lacks a credible basis for establishing a cost-benefit analysis of IVP.
  8. Limit the scope of reconfirming MAOP.
