With regard to postspill reviews, the spill office should determine whether the postspill reviews are an effective means for identifying areas for plan improvement and then take steps to either ensure the reviews are submitted or eliminate them from its regulations.
The requirement for a "post spill review" has routinely run into legal challenges; the responsible party (RP) is reluctant to admit fault or deficiencies in their plan due to liability issues. The investigations conducted by OSPR and/or the US Coast Guard as the cause of the spill is a better source for this information, which can then be addressed in the RP's contingency plan, if appropriate. Therefore, rulemaking was promulgated that removed the requirement for a "post spill review." These changes went into effect on June 2, 2011. (See 2011-041 p. 143)
Agency responses received after June 2013 are posted verbatim.
