36 CFR § 9.121 - What monitoring and reporting is required for all operators?
(b) The Regional Director may determine that third-party monitors are required when necessary to protect federally owned or administered lands, waters, or resources of System units, visitor uses or experiences, or visitor or employee health and safety.
(1) The Regional Director's determination will be based on the scope and complexity of the proposed operation and whether the park has the staff and technical ability to ensure compliance with the operations permit and any provision of this subpart.
(2) A third-party monitor will report directly to the NPS at intervals determined by the Superintendent, and you will be responsible for the cost of the third party monitor. We will make the information reported available to you upon your request.
(3) Third party monitors must disclose to the NPS any potential conflicts of interest that could preclude objectivity in monitoring an operator's compliance with the operations permit and any provision of this subpart.
(c) You must notify the Superintendent of any accidents involving serious personal injury or death and of any fires or spills on the site as soon as feasible, but no later than 24 hours after the accident occurs. You must submit a full written report on the accident to the Superintendent within 90 days after the accident occurs.
(d) You must notify the Superintendent as soon as feasible, but no later than 24 hours after the discovery of any cultural or scientific resource you encounter that might be altered or destroyed by your operation. You must cease operations if necessary and leave the discovered resource intact until the Superintendent provides you with instructions. The Superintendent will determine, within 10 working days after notification what action will be taken with respect to the discovery.
(e) Upon the Superintendent's request, you must submit reports or other information necessary to verify compliance with your permit or with any provision of this subpart. To fulfill this request, you may submit to the NPS reports that you have submitted to the State under State regulations, or that you have submitted to any other Federal agency.
