The department shall take the following actions with regard to the tracking of indirect oversight costs:
(a) Ensure that pro rata costs are allocated appropriately to all departmental activities, so that the department’s program will only bear these pro rata costs in proportion to the benefits received by potentially responsible parties.
(b) Routinely include operating expenses in the indirect oversight costs and allocate those expenses using processes that ensure that the department’s program only bears indirect oversight costs in proportion to the benefits received by potentially responsible parties.
(c) Exclude, from indirect oversight costs, the costs of grant development and administration, fee administration, contract development and administration, and public and governmental inquiries.
