Recent Recommendation Status Updates
Each recommendation the CSB issues is monitored by CSB staff from the time it is issued to closing. CSB staff evaluate recipient responses, and the Board votes to assign status designations to recommendations based on staff evaluation. This page highlights recommendations for which the Board has recently voted to change the status of the recommendation. For more information on how the CSB defines its recommendation statuses, please visit the Recommendations Frequently Asked Questions page.

Revise API RP 939-C: Guidelines for Avoiding Sulfidation (Sulfidic) Corrosion Failures in Oil Refineries to establish minimum requirements for preventing catastrophic rupture of low-silicon carbon steel piping. At a minimum:
a. Require users to identify carbon steel piping circuits susceptible to sulfidation corrosion that may contain low-silicon components. These circuits have the potential to contain carbon steel components that were not manufactured to the American Society for Testing and Materials (ASTM) A106 specification and may contain less than 0.10 weight percent silicon content.
b. For piping circuits identified to meet the specifications detailed in 2012-03-I-CA-R26(a), require users to either (1) enact a program to inspect every component within the piping circuit once, known as 100 percent component inspection (per the requirements established pursuant to recommendation 2012-03-I-CA-R28(c)), or (2) replace the identified at-risk carbon steel piping with a steel alloy that is more resistant to sulfidation corrosion.
c. If low-silicon components or components with accelerated corrosion are identified in a carbon steel piping circuit meeting the specifications detailed in 2012-03-I-CA-R26(a), require designation of these components as permanent Condition Monitoring Locations (CMLs) until the piping components are replaced.

Final Report Released On: October 21, 2015
2010-02-I-PR-9
Develop a single publication or resource describing all API standards and other relevant codes, standards, guidance, and information for filling operations of aboveground storage tanks in petroleum facilities that describes:
a. The required design and management practices for control of filling operations;
b. The minimum set of independent overfill prevention safeguards if the control fails; and
c. Operational challenges (e.g., monitoring/calculating flow rates, ability to maintain constant line pressures, and influences of valve cracking) related to loading multiple tanks concurrently from a single product source.
