establish procedures to ensure that authorized and properly identified representatives of the Secretary will inspect at least once annually each lease site producing or expected to produce significant quantities of oil or gas in any year or which has a history of noncompliance with applicable provisions of law or regulations; and

establish and maintain adequate programs providing for the training of all such authorized representatives in methods and techniques of inspection and accounting that will be used in the implementation of this chapter.

The Secretary shall audit and reconcile, to the extent practicable, all current and past lease accounts for leases of oil or gas and take appropriate actions to make additional collections or refunds as warranted. The Secretary shall conduct audits and reconciliations of lease accounts in conformity with the business practices and recordkeeping systems which were required of the lessee by the Secretary for the period covered by the audit. The Secretary shall give priority to auditing those lease accounts identified by a State or Indian tribe as having significant potential for underpayment. The Secretary may also audit accounts and records of selected lessees and operators.

The Secretary may enter into contracts or other appropriate arrangements with independent certified public accountants to undertake audits of accounts and records of any lessee or operator relating to the lease of oil or gas. Selection of such independent certified public accountants shall be by competitive bidding in accordance with chapters 1 to 11 of title 40 and division C (except sections 3302, 3307(e), 3501(b), 3509, 3906, 4710, and 4711) of subtitle I of title 41, except that the Secretary may not enter into a contract or other arrangement with any independent certified public accountant to audit any lessee or operator where such lessee or operator is a primary audit client of such certified public accountant.

All books, accounts, financial records, reports, files, and other papers of the Secretary, or used by the Secretary, which are reasonably necessary to facilitate the audits required under this section shall be made available to any person or governmental entity conducting audits under this chapter.
