Securities Exchange Act of 1934
Rule 12h-3

March 29, 2011

Response of the Office of Chief Counsel
Division of Corporation Finance

Based on the facts presented, the Division will not object if Constar stops filing periodic and current reports under the Securities Exchange Act of 1934, including its annual report on Form 10-K for the year ended December 31, 2010. In reaching this position, we note that Constar has filed a post-effective amendment removing from registration unsold securities under its effective registration statement on Form S-8, and that post-effective amendment is effective. We assume that, consistent with the representations made in your letter, Constar will file a certification on Form 15 making appropriate claims under Exchange Act Rules 12g-4 and 12h-3 on or before the due date of its Form 10-K for the year ended December 31, 2010.

This position is based on the representations made to the Division in your letter. Any different facts or conditions might require the Division to reach a different conclusion. Further, this response expresses the Division’s position on enforcement action only and does not express any legal conclusion on the question presented.

Sincerely,

Michael J. Reedich
Special Counsel
