STATEMENT OF WORK

Phase I Environmental Site Assessment for Fee-to-Trust Land Acquisition

Bureau of Indian Affairs – Great Plains Region

A. GENERAL

The purpose of this Statement of Work (SOW) is to establish the requirements for conducting a Phase I Environmental Site Assessment (ESA) for property proposed for acquisition by the United States in trust for the benefit of an Indian Tribe or individual Indian.

The purpose of the Phase I ESA is to identify existing or potential environmental conditions that could affect the proposed fee-to-trust acquisition and to assist the BIA in determining whether additional environmental investigation is warranted. The Phase I ESA shall provide the BIA with sufficient information to evaluate potential environmental liabilities and determine whether additional environmental investigation or assessment may be necessary before the property is accepted into trust.

The work shall be performed in accordance with applicable federal requirements and generally accepted professional standards for Phase I Environmental Site Assessments, including the current applicable ASTM standard.

B. PROPERTY LOCATION

The Phase I ESA shall be conducted for the property identified by the BIA as the subject of the proposed fee-to-trust acquisition.

The Government will provide the contractor with available information concerning the property, including the property address, legal description, parcel information, maps, and other available documentation necessary to conduct the assessment.

C. SCOPE OF WORK

The contractor shall conduct a Phase I Environmental Site Assessment of the subject property.

The assessment shall include, at a minimum, the following activities:

1. Records Review

The contractor shall review reasonably ascertainable environmental and historical information concerning the subject property and surrounding properties.

The records review shall include, as applicable:

• Federal, state, tribal, and local environmental databases;

• Hazardous waste and solid waste records;

• Underground storage tank records;

• Leaking underground storage tank records;

• Superfund and contaminated-site records;

• CERCLA and RCRA records;

• State and tribal environmental records;

• Historical land-use information;

• Historical aerial photographs;

• Historical maps;

• Property ownership and land-use information;

• Available regulatory records; and

• Other reasonably ascertainable information relevant to environmental conditions at the property.

The contractor shall evaluate historical property uses to identify activities that may have resulted in releases or threatened releases of hazardous substances or petroleum products.

2. Site Reconnaissance

The contractor shall conduct an on-site visual inspection of the subject property and, to the extent applicable, adjoining properties.

The site reconnaissance shall evaluate visible evidence of potential environmental concerns, including:

• Aboveground storage tanks;

• Underground storage tanks or evidence of former tanks;

• Petroleum storage or dispensing areas;

• Hazardous substance storage;

• Chemical storage;

• Waste storage or disposal areas;

• Drums and containers;

• Dumping or debris areas;

• Stressed vegetation;

• Electrical equipment containing or potentially containing regulated substances;

• Floor drains, sumps, pits, or other potential pathways;

• Wells;

• Septic systems;

• Landfills;

• Evidence of spills or releases;

• Current and historical industrial or commercial activities; and

• Other conditions that may indicate potential environmental contamination.

Photographs shall be taken to document relevant site conditions and areas of potential environmental concern.

3. Interviews

The contractor shall conduct interviews, as appropriate, with knowledgeable persons identified by the Government, property owner, occupant, Tribal representative, or other available sources.

Interviews may include individuals with knowledge of:

• Current and historical property use;

• Past releases or spills;

• Waste disposal practices;

• Storage of hazardous substances or petroleum products;

• Underground or aboveground storage tanks;

• Prior environmental investigations; and

• Other environmental conditions affecting the property.

4. Environmental Condition Evaluation

The contractor shall evaluate the information obtained through records review, site reconnaissance, and interviews to identify environmental conditions associated with the property.

The assessment shall identify, as applicable:

• Recognized Environmental Conditions (RECs);

• Controlled Recognized Environmental Conditions (CRECs);

• Historical Recognized Environmental Conditions (HRECs);

• Significant data gaps; and

• Other potential environmental concerns requiring consideration by the BIA.

The contractor shall provide a clear explanation and supporting documentation for each identified environmental condition.

D. PHASE I ESA REPORT

The contractor shall prepare a written Phase I ESA Report documenting the results of the assessment.

The report shall include, at a minimum:

1. Executive Summary.

2. Property identification and legal description.

3. Site location map.

4. Property description and current use.

5. Adjoining property descriptions and uses.

6. Historical property use.

7. Records/database review.

8. Regulatory records review.

9. Site reconnaissance findings.

10. Interview documentation.

11. Photographic documentation.

12. Identification and evaluation of RECs, CRECs, and HRECs.

13. Identification of significant data gaps.

14. Conclusions and recommendations.

15. Supporting maps, figures, photographs, and documentation.

16. Environmental database search results.

17. References and sources reviewed.

18. Statement of qualifications of the Environmental Professional.

The report shall clearly state whether additional environmental investigation is recommended and explain the basis for any recommendation.

E. DELIVERABLES

The contractor shall provide:

1. One electronic draft Phase I ESA Report for BIA review.

H. PROJECT COMPLETION

The project shall be considered complete upon delivery and Government acceptance of the final Phase I Environmental Site Assessment Report and all required supporting documentation.

If the Phase I ESA identifies recognized environmental conditions or other concerns requiring additional investigation, the contractor shall clearly identify those concerns and provide recommendations for appropriate next steps. Any Phase II Environmental Site Assessment, sampling, testing, remediation, or other additional investigation shall be outside the scope of this SOW unless separately authorized by the Government.
