Assistance with Effect Determinations for the California Plant Materials Center’s Proposed Upgrades

Part I: General Information

It is the mission of the Natural Resources Conservation Service (NRCS) to provide leadership in a partnership effort to help people conserve, maintain, and improve our nation’s natural resources and environment. The NRCS Plant Materials Center (PMC), a 106-acre working facility in Lockeford, assists with this mission by conducting studies, demonstrating Agency conservation practices, and providing a centrally located training location. The PMC is federally owned and has been in operation for over 50 years

A. Introduction/Background

The NRCS is soliciting quotes from Contractors for the completion of an impact assessment for proposed upgrades to the PMC. These upgrades would in part repurpose a currently underutilized storage area into a 1000 square foot training and conference space. This work constitutes a Proposed Action under the National Environmental Policy Act (NEPA) and an Undertaking under National Historic Preservation Act (NHPA). Therefore, a review for potential impacts to historic properties per Section 106 of the NHPA (Section 106) within the area of potential effects (APE) is necessary before approval of the project.

B. Scope

Contractor will prepare a Work Plan and Cultural/Historic Resources Technical Report. The deliverables for this Task must support the NRCS’s environmental review per NEPA and finding of effect per NHPA Section 106. The Contractor will submit (a.) a brief Work Plan to the NRCS for approval outlining planned studies of the Affected Environment/APE for Alternative 1 to identify cultural resources/historic properties that could be impacted by the Proposed Action. Once approval of the Work Plan is obtained, the Contractor will (b.) carry out the studies and (c.) submit a draft cultural/historic resources technical report to the NRCS for review. The draft technical report will be reviewed by the NRCS, and the final technical report will incorporate any comments or requests for revision provided by the NRCS. The draft and final technical reports must be suitable for supporting the NRCS’s consultation with the State Historic Preservation Officer (SHPO), Tribal Historic Preservation Officers (THPO), and Native American tribes pursuant to Section 106 and will be appended to the Environmental Evaluation. The NRCS will provide appropriate information to the Contractor regarding consultation with the SHPO/ THPO and Native American tribes.

a. Work Plan:

i. Includes a thorough description of the Alternative 1 to include the anticipated the extent of ground disturbances (including borrow sites) or modifications/demolitions of buildings/structures.

ii. Describes and illustrates a recommended area of potential effects (APE) for the Affected Environment of Alternative 1, and a research design for studies to identify cultural resources/historic properties including field surveys and background research.

iii. Must be approved by the NRCS prior to scheduling or conducting any field work so that requests from tribal consulting partners can be considered and/or accommodated.

b. Field Study Effort:

i. Prior to commencing the pedestrian inventory, Contractors will complete a review of records for information for the task order regarding previous cultural resources inventories and previously recorded cultural resource sites.

ii. Contractors will complete an intensive pedestrian cultural resources inventory of the indicated APE to identify historic properties that may be adversely affected as a result of the proposed undertaking.

c. Draft and Final Technical Reports:

i. Include information contained in the Work Plan regarding the Affected Environment/

APE and the research design for field studies/background research

ii. Include results of a records search conducted at the appropriate California Historical

Resources Information Center (CHRIS) addressing the Affected Environment/APE for Alternative 1. The CHRIS results must tabulate resource descriptions, state resource numbers, and the known or recommended National Register of Historic Places (NRHP) eligibility status of each.

iii. Include appropriate background research including results of historical map research and literature review relevant to the Affected Environment/APE for Alternative 1.

iv. Include the results of surveys of the Affected Environment/APE for Alternative 1. The results must provide a recommended NRHP eligibility determination for any cultural/historic resources that could be impacted by the Proposed Action pursuant to 36 CFR § 60.4, and provide a clear and succinct analysis of how such resources could be affected pursuant to the criteria of effect at 36 CFR § 800.5. Note that appropriate expertise is required by NHPA Sections 106 and 112 to provide NRHP evaluation recommendations based on the type of resources. This would include, but is not limited to, recommendations regarding the built environment.

v. Contain appropriate documentation of identified archaeological and historical resources.
