City of Pleasanton’s Recycled Water Project Inadvertent Discovery Plan

INADVERTENT DISCOVERY PLAN

A Plan and Procedure for Dealing with the Inadvertent

Discovery of Cultural Resources

City of Pleasanton#s Recycled Water Project

1.0 INTRODUCTION

The State Water Resources Control Board (State Board) is responsible for administering the

State Revolving Fund (SRF) Loan Program and may provide funds on behalf of the U.S.

Environmental Protection Agency (EPA) for the construction of the City of Pleasanton’s (City)

proposed Recycled Water Project (Proposed Project/Action). EPA has delegated authority to the

State Board for examining cultural resources and communicating with the parties concerning such

examinations. This document supplements the previous reports conducted for the City of Pleasanton’s

Recycled Water Project including but not limited to the following documents prepared for the City by

SMB Environmental, Inc. (SMB):

• June 2014 Public Draft Initial Study/Mitigated Negative Declaration (IS/MND) and

Environmental Assessment/Finding of No Significant Impact (EA/FONSI);

FEDERAL NEXUS

Due to the potential funding under the SRF Loan Program, this project is considered a Federal

undertaking and, therefore, is subject to Section 106 of the National Historic Preservation Act of 1966,

and its associated regulations at 36 CFR Part 800.

Federal law stipulates that in the case of an undertaking that utilizes federal money, a project will adhereto provisions of the National Historic Preservation Act of 1966 (as amended). As the lead agency, the

State Board is responsible for all aspects of 36 CFR 800 in dealing with the treatment of cultural

resources and the consultation of concerned parties. As previously mentioned, EPA has delegated

authority to the State Board for examining cultural resources and communicating with the parties

concerning such examinations. Potentially concerned parties include: the City of Pleasanton, the Ohlone

Indian Tribe, the Trina Marine Ruano Famity, the Coastanoan Rumsen Carmel Tribe, the Amah

Mutsun Tribal Band of Mission San Juan Bautista, the Indian Canyon Mutsun Band of Coastanoan, the

Muwekma Ohlone Indian Tribe of the San Francisco Bay Area, and the Office of Historic Preservation

(OHP).

Any staff members of State Board and/or the City, their contractors, or subcontractors are required to

halt construction if they observe or identify any cultural materials and will provide a professionalarchaeologist adequate time to assess, record, and potentially analyze any resources that might be

uncovered. The OHP will be notified of any discoveries that occur during construction.

This document serves as the plan for dealing with any discoveries of human skeletal remains, artifacts,

sites, or any other cultural resources eligible for listing in the National Register of Historic Places

(NRHP). This plan is intended to provide guidance to City personnel so they can:

• Comply with applicable Federal and State laws and regulations, particularly 36CFR 800 (asamended January 11, 2001) of the regulations that implements Section 106 of the NationalHistoric Preservation Act of 1966;

• Describe to regulatory and review agencies the procedures that City of Pleasanton will follow to prepare for and deal with inadvertent discoveries; and

• Provide direction and guidance to project personnel on the proper procedures to be followed

should an inadvertent discovery occur.

2.0 INADVERTENT DISCOVERY OF HUMAN SKELETAL REMAINS ON NON-FEDERAL

AND NON-TRIBAL LAND IN THE STATE OF CALIFORNIA

If ground-disturbing activities encounter human skeletal remains during the course of construction, then

all activity must cease that may cause further disturbance to those remains and the area of the find must

be secured and protected from further disturbance. In addition, the finding of human skeletal remains

must be reported to the Alameda County Coroner and local law enforcement in the most expeditiousmanner possible. The remains should not be touched, moved, or further disturbed.

The Alameda County Coroner will assume jurisdiction over the human skeletal remains and make a

determination of whether those remains are forensic or non-forensic. If the county coroner determines

the remains are non-forensic, then they will report that finding to the OHP who will then take

jurisdiction over the remains and report them to the appropriate cemeteries and affected tribes. If human

remains are discovered, work will be halted and the Alameda County Coroner will be contacted. The

Alameda County Coroner will make a determination of whether the remains are Native American or


144/150

%


non-Native American and report that finding to any appropriate cemeteries and affected tribes. If either

the Alameda County Coroner, the On-site Archaeologist and/or the Native American Monitor believes

the remains to be Native American and not under the Alameda County Coroner’s jurisdiction, then the

Alameda County Coroner has 24 hours to notify the native American Heritage Commission (NAHC).

The NAHC then will designate the Most Likely Descendent (MLD), who has 48 hours to make

recommendations to the property owner or authorized representative. Work will be suspended in the

area of the human remains until the MLD’s recommendations are implemented. The City will ensurethat any identified human remains will be secured while they are left in place while treatment decisions

are in progress.

ADDITIONAL RESPONSIBILITIES AND INFORMATION

A. The area of work stoppage will be adequate to provide for the security, protection, and

integrity of the skeletal remains, in accordance with California State law. The City’s

Project/Action Engineer will be responsible for taking appropriate steps to protect the

discovery. At a minimum, the immediate area will be secured to a distance of a hundred

(100) feet from the discovery. Vehicles, equipment, and unauthorized personnel will not be

permitted to traverse the discovery site.

B. The State Board and the City acknowledges that any find of human skeletal remains may be a

burial of Native American ancestry. It is further acknowledged that the concerned native

American Tribes are extremely sensitive about ancestral burials, and that the find must be

treated confidentially.

C. Nothing in this agreement is intended or shall be construed to diminish or affect in any way the

right of the Tribes to take any lawful action to protect Native American graves from

disturbance or desecration, or to protect the Tribes’ rights under cemetery and Native

American graves protection laws, or other applicable laws.

D. This information is covered by the Section 304 of the National Historic Preservation Act;

Section 9(a) of the Archaeological Resources Protection Act; Executive Order 13007;

California Health and Safety Code 7050.5; California Public Resources Code 5097.9 through

5097.99 as amended per Assembly Bill 2641; and Section 6254.10 of the California State

Government Code and specific components of the records are exempt from disclosure (RCW

42.17.310(1)(k)) to avoid the looting or depredation of such sites.

PROCEDURES FOR THE DISCOVERY OF ARCHAEOLOGICAL RESOURCES

A. If any staff members of State Board and/or the City, their contractors, or subcontractors,

including archaeological monitors, believe that he or she has encountered cultural or

archaeological remains of any kind, all work at and adjacent to the discovery shall

immediately cease. He or she will inform the Project’s Resident Engineer and the State Board.

Attachment A provides a contact list of individuals that should be contacted if cultural resources

are encountered. The area of work stoppage will be adequate to provide for the security, protection, and integrity of the archaeological discovery. A cultural resource discovery could

be prehistoric-period or historic-period in age and consist of (but not limited to):

• Areas of charcoal or charcoal-stained soil and stones;

• Stone, tools, or waste flakes (i.e., an arrowhead or stone chips);

• Bone, burned rock, or mollusk shell, whether or not seen in association with stone tools or


145/150

&


chips;

• clusters of tin cans, ceramics, flat glass, or bottles, concentrations of brick, or logging,mining, or agricultural equipment.

B. The State Board’s Projects Manager will consult with the On-site Project

Archaeologist/Monitor to

determine if the remains are archaeological and greater than 50years old. If the On-Site Project Archaeologist/Monitor believes that the discovery is a

cultural resource, he or she and the State Board’s Projects Manager will discuss with the

City’s Resident Engineer and steps will be taken to protect the discovery site. At a minimum,

subsurface disturbances will stop and the area adjacent to the discovery will be secured.

Vehicles, equipment, and unauthorized personnel will not be permitted to traverse the

discovery site. Any newly discovered archaeological resource would be considered eligible

to the NRHP until determined otherwise by the OHP. Work in the immediate area will not

resume until treatment of the discovery has been completed following the provisions for

treating archaeological/cultural material as set forth in Appendix B.

C. The State Board Project Manager and the On-site Project Archeologist/Monitor will contact the

OHP to assist in the significance evaluation of all inadvertent discoveries of cultural

resources. Any discovery deemed eligible for listing in the NRHP will be assessed and treated

according to the provisions set forth in Appendix A of this document.

D. The State Board will immediately contact the OHP (Attachment A) for consultation regarding

National Register eligibility of any new discovery. If the federal and state agency

representatives determine that the discovery is an eligible cultural resource, they and concerned

Native American Tribe(s), as appropriate, will consult to determine appropriate treatment to be

presented and agreed upon in a Memorandum of Agreement (MOA) or other appropriate

documentation. Mitigation measures will be developed in consultation with the State Board

and the OHP, and the affected tribes (where appropriate), which could include avoidance

through redesign, conducting data recovery and/or relocating materials or remains. Agreed

upon treatment measures performed by the City include protecting the resources in place, or

data recovery such as mapping, photography, limited probing, and sample collection, or other

measures.

E. This information is covered by the Section 304 of the National Historic Preservation Act;

Section 9(a) of the Archaeological Resources Protection Act; Executive Order 13007;

California Health and Safety Code 7050.5; California Public Resources Code 5097.9 through

5097.99 as amended per Assembly Bill 2641; and Section 6254.10 of the California State

Government Code and specific components of the records are exempt from disclosure (RCW

42.17.310(1)(k)) to avoid the looting or depredation of such sites.

Secretary of Interior’s standards shall directly observe the excavation process during

construction within the vicinity of the Native American archeological resources: P-01-

000066 (CA-ALA-46) and P-01-000139 (CA-ALA-413)! In the event that any prehistoric or

historic subsurface cultural resources are discovered during ground disturbing activities, allwork within 100 feet of the resources shall be halted. The On-site Archeologist Monitor

will contact the State Board Project Manager who will then contact the OHP to immediately

report all discoveries of cultural resources that are potentially eligible for listing in the

NRHP. Construction will be immediately halted within the immediate area of the discovery

and the scene will be protected until the State Board has arranged for the discovery to be

identified by the On-site Professional Archaeologist and the OHP. If the discovery is

determined to be a significant historic or archaeological site, or consists of Native

American human remains, the OHP, the State Board, and the Tribe(s) will be consulted as

appropriate to determine the course of action.

2. On May 5, 2014, ten (10) Native American groups and individuals were contacted to help

provide information regarding the potential to find Native American Resources in the

Project’s Area of Potential Effect. To date, no responses have been received. Specifically,

no requests of having a Native American monitor to be present during ground-disturbing

activities and/or to be contacted in the case of inadvertent discovery of human remains. As

a result, at the time of this Plan, a specific Native American Monitor has not been chosen

for the construction of ground-disturbing activities. However, if the On-site Archeological

Monitor shall discover any Native American resources or human remains during

construction, the Native American Tribes in Attachment A will be contacted immediately.

3. Prior to the initiation of ground-disturbing activities, the On-Site Archeological Monitor

will conduct a short awareness training session for all construction workers and supervisory

personnel. The course will explain the importance of, and legal basis for, the protection of

significant archeological resources. Each worker will also learn the proper procedures to

follow in the event that cultural resources and/or human remains/burials are uncovered

during construction activities, including work curtailment or redirection and to immediately

contact their supervisor and the On-site Archeological Monitor. It is recommended that this

worker education session include visuals of artifacts (prehistoric and historic) that might be

encountered in the project vicinity, and that it take place on the construction site

immediately prior to the start of construction. The approximately 30-45 minute training

session may be conducted on-site by video, Powerpoint presentation, and or other related

material.

4. The On-site Archeological Monitor will inspect, from a safe distance during excavation

activities, mechanical trenching, backdirt piles, or associated ground disturbance for


148/150

evidence of prehistoric, historic, and/or other culturally sensitive materials.

5. The On-site Archeological Monitor shall complete a daily log for each day of the

monitoring or other cultural resource activities conducted during the monitoring period.

The logs will track the cultural resources monitoring program, where monitoring was

occurring, detail of any discoveries, describe any actions taken, and describe any non-

compliance incidents. If warranted by the his/her observations, the On-Site ArcheologicalMonitor may halt or redirect construction activities to examine soils or the interior of a

trench, and to allow for sufficient time to evaluate and potentially remove a find.

6. As part of the construction team, the On-site Archeologist Monitor will ensure proper

documentation and assessment of any discovered cultural resources. Non-intrusive field

documentation of all human remains will be undertaken immediately. All prehistoric and

historic cultural material discovered during project construction will be recorded by the On-

Site Professional Archaeologist/Monitor on standard cultural resource site forms, or on

isolate forms using standard techniques. Site overviews, features, and artifacts will be

photographed; stratigraphic profiles and soil/sediment descriptions will be prepared for

subsurface exposure. Discovery locations will be documented on scaled site plans and site

location maps.

7. Sites discovered during construction will be assumed eligible pending evaluation by an

archeologist meeting the Secretary of Interiors Standards under Criterion D for inclusion in the

National Register of Historic Places (NRHP) for the purposes of Section 106 compliance, in

accordance with 36 CFR 800.13(c).

8. Where complex or extensive cultural remains are encountered, the State Board and the OHP

will jointly determine the appropriate level of documentation and treatment of the resources

after consultation with the concerned tribal representatives.

9. The State Board and the OHP will decide when construction may continue at the discovery

location. Where cultural resources are encountered during construction, but additional project effects to the resources are not anticipated, project construction may continue while

documentation and assessment of the cultural resources proceed. If continued construction

is likely to cause additional impacts to such resources, project activities within a radius of

100 feet of the discovery will cease until the Professional Archaeologist has documented the

site, evaluated its significance, and assessed potential effects to the site.

10. Cultural features, horizons, and artifacts detected in buried sediments may require further

evaluation using hand-dug test units to clarify aspects of integrity, stratigraphic context, or

feature function. Units may be dug in controlled fashion to expose features, collect

radiocarbon or animal/plant macrofossil samples from undisturbed contexts, or interpret

complex stratigraphy. A test excavation unit or small trench might also be used to cross-

section a feature to determine if an intact occupation surface is present. Test units will be used only when necessary to gather information on the nature, extent, and integrity of

subsurface cultural deposits to evaluate the site’s potential to address significant research

domains. Excavations will be conducted using state-of-the-art techniques for controlling

provenience of recovered remains.

11. Sediments excavated for purposes of cultural resources investigations will be screened

through 1/8-inch or !-inch mesh depending on the soil types encountered. Spatial

information, depth of excavation levels, natural and cultural stratigraphy, presence or


149/150

absence of cultural material and depth of sterile soil, regolith, or bedrock will be recorded

for each probe on a standard form. Test excavation units will be recorded on unit-level

forms, which include plan maps for each excavated level, and material type, number and

vertical provenience (depth below surface and stratum association where applicable) for all

artifacts recovered from the level. Radiocarbon and macrofossil samples will be taken from

intact subsurface features exposed by shovel/auger probes or test units. A stratigraphic

profile will be drawn for at least one wall of each test excavation unit.

12. All prehistoric and historic artifacts collected from the surface and from probes and

excavation units will be analyzed, catalogued, and temporarily curated at a facility meeting

the Secretary of Interior’s standards for curation. Ultimate disposition of cultural materials

will be determined in consultation with the State Board, OHP, and concerned tribes.

13. Within 90 days of conclusion of fieldwork, a management summary describing any and all

monitoring activities and resultant archaeological excavations will be provided to State

Board by the on-site professional archeologist and the City’s Project Engineer/Construction

Manager. The State Board Project Manager will forward the report to the OHP and

concerned tribes.

14. If construction activity exposes human remains (burials, or isolated teeth or bones),

construction in the immediate vicinity of the find will be halted. State Board will follow

procedures outlined under section 2.0 of the Inadvertent Discovery Plan.

15. Treatment of Native American Remains: If either the Alameda County Coroner, the On-site

Archaeologist and/or the Native American Monitor believes the remains to be Native

American and not under the Alameda County Coroner’s jurisdiction, then the Alameda

County Coroner has 24 hours to notify the native American Heritage Commission

(NAHC). The NAHC then will designate the Most Likely Descendent (MLD), who has 48

hours to make recommendations to the property owner or authorized representative. Work

will be suspended in the area of the human remains until the MLD’s recommendations are

implemented. The City will ensure that any identified human remains will be securedwhile they are left in place while treatment decisions are in progress.

16. Treatment of Non-Native American Historic Remains: If the cultural remains are determined

to be historic non-Native American remains, treatment will be determined by the On-Site

Archeologist/Monitor in consultation with the State Board and OHP.

17. Curation: The State Board will ensure that eligible artifacts are curated appropriately.

Collected artifacts and samples that are determined historically significant would be

curated for future use for research, interpretation, preservation, and cultural resource

management activities using Department of the Interior federal guidelines for curation (36

CFR 79). Artifacts and associated documents resulting from data recovery, including maps,

photographs, field notes, bone, shell, soil samples, wood and other botanical samples, andfire-modified rock, would be curated following analysis. Artifacts, samples, and records

would be prepared for curation. A sample of selected artifact categories and sediments

would be retained for curation. For cultural resources that are determined “significant” State

Board will, in consultation with the OHP and affected tribes, identify appropriate facilities,

provide and pay for long-term curation of prehistoric, ethnohistoric, and historic artifacts,

data samples, and records resulting from the project investigations. The State Board will

consult with affected federally and non- federally recognized Tribes to reach agreement

about permanent storage of some of the materials.
