Necessary costs

Necessary costs means necessary response costs as required by section 111(2) of CERCLA for Fund reimbursement of a preauthorized response action. Necessary response costs are costs determined to be:
(1) Required (based upon the site-specific circumstances);
(2) Reasonable (nature and amount do not exceed that estimated or which would be incurred by a prudent person);
(3) Allocable (incurred specifically for the site at issue); and
(4) Otherwise allowable (consistent with the limitations and exclusions under the appropriate Federal cost principles). See OMB Circular A–122 (non-profit organizations); OMB Circular A–87 (States and political subdivisions); and 48 CFR part 31, subparts 31.1 and 31.2 (profit-making organizations).
