APPENDIX C: PALEONTOLOGICAL MONITORING AND PROTECTION PLAN

CLEVELAND-LLOYD DINOSAUR QUARRY BUILDING REPLACEMENT

All paleontological field work including excavation of and monitoring for paleontological resources would be conducted or supervised by paleontologists that meet the qualifications as described in 43 CFR §49.110, and any non-BLM paleontologists would provide application details as described in 43 CFR § 49.115 and be authorized by the BLM prior to excavation and monitoring activities.

Part 1: Pre-Construction

Prior to building demolition and construction, a contracted, BLM-permitted paleontologist will perform excavation and collection or stabilization of the paleontological resources, by completing the following steps:

Providing a work plan and schedule to the BLM for review and approval before initiating excavation or monitoring activities, Stabilizing the site to the extent required for subsequent construction including capping exposed, to be left in situ fossils with plaster jackets, covering the bonebed, and returning sediments into the excavation area, Documenting fossils in place using the original mapping strategy before covering or removal, Removing fossils depending on proximity to defined construction activity type, Delivering the excavated material to a BLM-approved repository for preparation and curation, and Providing a report (contents listed below in Part 3: Reporting).

The bonebed boundary and other sensitive areas will be identified and flagged by a BLM paleontologist before arrival by the construction contractor and staff and before any construction activity is initiated.

Prior to construction activity, a BLM paleontologist will determine how in place paleontological resources encased within plaster jackets would be best protected from construction activities (e.g., using stall mats) and clearly mark resources for avoidance by construction crews.

Equipment and materials staging locations would be identified and flagged by a BLM-approved paleontologist before any construction activity is initiated to ensure avoidance or protection of known paleontological resources.

Part 2: Construction

Before any construction activity, a BLM paleontologist would brief BLM-approved paleontologists (i.e., paleontological monitors), construction contractor supervisor, and construction staff on the following:

Examples of bone in situ for recognition during construction, Appendix C Page 2

Practices for minimizing impact to paleontological resources while working by following this protection plan, and Maps that illustrate sensitive, avoidance, and staging areas.

A paleontological monitor would be present on-site for the following demolition and construction activities and would document the following activities using photos and field notes (to be provided to the Authorized Officer at conclusion of the project):

Removal of existing surface and subsurface structures including footers, Ground disturbing activity (i.e., any disturbance other than walking or driving in the area), and Addition of new structures within or within 3 feet of the flagged sensitive areas.

The paleontological monitors and construction staff would agree upon the following procedures:

Construction staff would notify paleontological monitors before each of the demolition and construction activities listed above and Paleontological monitors would visually and verbally signal the need for a work stoppage in the case of a potential paleontological resource discovery or impact and need for closer examination.

In the case that the construction activities listed above are being completed in more than one area, there would be a monitor per location or if only one monitor is present, only one such activity would proceed at any given time.

In the absence of a paleontological monitor, the construction contractor and staff would only complete work outside of the flagged sensitive areas that does not contact the surface or subsurface (e.g., removal of non-surface and subsurface materials, window installs, roofing, etc.).

If previously unknown paleontological resources are discovered or previously documented paleontological resources are exposed to risk (e.g., machinery in close proximity, crushing, drainage issues, etc.) during the construction process, construction would pause immediately, and the BLM Authorized Officer would be notified to facilitate resource documentation, evaluation, and excavation or stabilization by a BLM-permitted paleontologist. Collections would be delivered immediately to the BLM-approved repository or stored in the Visitor Center until they could be delivered to the BLM-approved repository.

Construction contractors would provide a work plan and schedule no later than two weeks prior to arrival. The construction contractor along with the paleontological monitors would update the BLM Authorized Officer weekly with upcoming general construction activities or when general construction activities or plans are altered. Daily updates may be needed early in the process or during specific portions of the project with higher potential to impact paleontological resources. The paleontological monitor(s) would submit a final report as described in the following section.

Part 3: Final Reporting

Appendix C Page 3

A report will be submitted by each BLM-permitted paleontologist (e.g., monitors and excavators) for the tasks they completed within 30 days of completion of their tasks unless otherwise approved by the BLM. Where applicable the report will include:

A description of excavated areas and an estimate of fossils collected (e.g., bones, bags, jackets), Recommendations as applicable for the project and an updated timeline for processing data and fossils, and Maps (created using grid-mapping based on the original CLDQ mapping strategy) and field notes of the excavated areas.
