**NOTE THIS IS FOR A SUPPLEMENTAL ENVIRONMENTAL ASSESSMENT (SEA)

SECTIONS/TASKS WILL BE ADDRESSED AS REQUIRED**

1.0 PURPOSE

The Department of the Air Force (DAF) is proposing to update the 2016 supplemental environmental assessment (SEA) incorporating any changes made since the document was signed. The Proposed Action is to continue implementation of the Falcon Hill EUL, as described in the 2008 WSD EUL SEA, and the 2016 SEA which is to lease approximately 550 acres of Air Force-owned property to a private developer. In accordance with the Air Force Civil Engineer Center EUL program, Hill AFB land would be leased to and redeveloped by a private company.

The overall goal of this task/delivery order is to prepare an Supplemental Environmental Assessment (SEA) that is technically and legally sufficient pursuant to provisions of the National Environmental Policy Act of 1969 [(NEPA), Title 42 United States Code (USC) Section 4321 et seq.], and 32 CFR 989, Environmental Impact Analysis Process (EIAP).

The Contractor shall provide services resulting in a project SEA with either a Finding of No Significant Impact (FONSI), a mitigated FONSI, or a determination that an Environmental Impact Statement is required. If analysis indicates the potential for significant environmental or socio-economic impacts the Contractor shall recommend to the DAF Government project lead one of the following:

· Mitigation measures to minimize impacts to less than significant (incorporated as part of the SEA document).

· Implementation of the No Action Alternative.

· Withdrawal of the SEA and the preparation of an Environmental Impact Statement (EIS).

75 Civil Engineer Group, Hill AFB will retain responsibility as the project proponent.

NOTE: Tasks and deliverables listed in this Statement of Work may not be required if data/records from previous documents are still applicable.

2.0 BACKGROUND

The SEA shall provide sufficient, documented information to analyze potential environmental effects associated with the Proposed Action described and shown in SOW Attachment A. The Proposed Action is to continue implementation of the Falcon Hill EUL, as described in the 2008 WSD EUL SEA and the 2016 SEA, which is to lease approximately 550 acres of Air Force-owned property to a private developer. In accordance with the Air Force Civil Engineer Center EUL program, Hill AFB land would be leased to and redeveloped by a private company. The Air Force would retain land ownership, but the developer would act as the property manager of the private sector leased assets. The Air Force would use funding from the EUL to construct new Air Force facilities to replace substandard facilities. The Proposed Action is the preferred alternative.

3.0 SCOPE OF WORK

7.0 INSTRUCTIONS FOR SEA RESOURCE ARSEA-SPECIFIC ANALYSIS

This section provides instruction for how the Contractor will conduct the analyses for the resource areas.

Section 7.1 – Air Quality Hill AFB is currently designated as an nonattainment, for one or more criteria air pollutants] and require assessment of effects to ensure compliance with National Ambient Air Quality Standards (NAAQSs). The Contractor shall confirm with 75 CEG/CEIE Air Quality Subject Matter Expert the attainment status of the location of the Proposed Action. For Air Quality analysis, the Contractor shall perform Air Quality EIAP assessments in accordance with AFMAN 32-7002, Environmental Compliance, and the most current versions of AF Air Quality EIAP Guide Volumes I and II and the AF Air Emissions Guides for Stationary, Mobile, and Transitory Sources. Additionally, the Air Quality EIAP assessments must include quantification and comparison (net change analysis) of all criteria pollutants and Greenhouse Gases (GHGs) for the proposed action (preferred and all alternatives).

The Contractor shall perform an air quality EIAP screening assessment at the lowest level possible (typically Level I, Exempt Action Screening, or Level II, Air Quality Quantitative Assessment) using the USAF’s Air Conformity Applicability Model (ACAM); NOTE: ACAM is for all assessments regardless of attainment status. For proposals that do not involve aircraft operations or basing/new weapons system bed downs, no further air quality analysis is required if results indicate that emissions of the proposal will not exceed air quality insignificance indicators/thresholds. For help with ACAM screening analysis, the ACAM Help Desk provides assistance in acquiring the ACAM software and technical support (the ACAM Help Desk can be reached at ACAM@SolutioEnv.com). Generally, use of any other air emissions analysis model is not acceptable. To deviate from utilizing ACAM, the contractor shall receive approval from the 75 CEG/CEIE Air Quality Subject Matter Expert.

All air quality assessments must be based on the reasonably foreseeable annual (Calendar Year) “net” (the total change or delta) direct and indirect emissions for each criteria pollutant associated with the action. Note that “net” means all emission sources that are removed and added associated with the action must be accounted for in the assessment. A net change analysis is an inventory of effects or impacts which ONLY includes emission sources/activities that will add to or reduce direct or indirect emissions. The Contractor shall only complete a net change assessment in ACAM (or other AFCEC/CZTQ approved tool); refer to the AF Air Quality EIAP Guide. If any annual net change emissions exceed the DAF insignificance indicators (attainment areas) or General Conformity Thresholds (nonattainment/maintenance areas), the contractor shall consult with 75 CEG NEPA Program Manager and the 75 CEG Air Quality Subject Matter Expert.

General Conformity Statement: For all Actions that will occur within a CAA designated nonattainment or maintenance area for one or more Criteria Pollutant(s), a General Conformity Analysis is required per 40 CFR 93 Subpart B. The Result of the Applicability Analysis must be specifically discussed within the Formal NEPA Document. If the annual net change in emissions exceed any of the General Conformity de minimis rates/thresholds [40 CFR 93.153 (b) and (c)] a General Conformity Determination will be required and will be contracted separately.

For air quality impact assessments, the contractor shall use the definition of the Region(s) Of Influence (ROI) in the AF AQ EIAP Guide Volume I, and that is currently approved by the 75 CEG Air Quality SME. There may be more than one ROI due to the physical spatial distribution of the emissions sources associated with the proposed action. Each non-contiguous area must be considered as a separate ROI. Each ROI requires a separate air quality EIAP assessment which must have a conclusion of air quality effects for the ROI. Additionally, for ROIs within areas that are classified as nonattainment or maintenance for any National Ambient Air Quality Standard (NAAQS), a separate General Conformity assessment for each nonattainment or maintenance area must be performed in tandem with the ROI’s overall air quality EIAP assessment (this is generally automated in ACAM if the nonattainment and maintenance areas are selected).

Construction Statement:

All proposed new exterior construction and demolition associated with the proposed action (preferred and alternatives) must be included in the air quality EIAP assessment. Generally, interior renovations/remodeling are NOT included in the air quality EIAP assessment. Emissions associated with the proposed construction and demolition activities must be estimated with ACAM and all assumptions for inputs and any deviations from ACAM defaults must be recorded (usually inserted in the ACAM text boxes for the construction/demolition sub-activities). Additionally, any proposed new or removed boilers (heating or industrial), generators, and/or tanks associated with the proposed new construction and demolition must be included in the ACAM analysis and air quality EIAP assessment.

Greenhouse Gas:

The Contractor shall ensure that the analysis includes an assessment of GHG emissions. The Contractor shall quantify GHG emission using ACAM. ACAM automates a relative comparison of GHG emission associated with each alternative as described in the Air Force Air Quality EIAP Guide Volume 1 of 2 available at www.aqhelp.com. Additionally, the contractor may use the procedures for a climate change qualitative assessment outlined in Chapter 6 of the Air Force Air Quality EIAP Guide Volume 1 of 2.

Potential air quality effects of proposed actions (preferred and alternate actions) must be appropriately documented. All preferred and alternate actions with air emissions must be included in a discussion on air quality and potential effects to air quality associated with the proposed action/alternatives in chapters associated with Affected Environment and Environmental Consequences. The following are a list of minimum requirements (more documentation may be needed depend on the specifics of the action):

· An overview of relevant laws and regulations relating to air quality must be present and must include a brief discussion of the Clean Air Act (CAA) and National Ambient Air Quality Standards (NAAQS - refer to 40 CFR Part 50).

· A description and discussion of each ROI with a brief description of the criteria pollutants and their current attainment status must also be present.

· A discussion of how the air assessments are conducted (e.g., net change analysis with ACAM), followed by a discussion of all attainment, maintenance and nonattainment areas.

· When an air quality assessment is conducted (i.e., Level I or II Air Quality EIAP Assessments) the total annual emissions results (for each criteria pollutant, and GHGs) and corresponding threshold/indicator must be tabulated by calendar year for the preferred action and each alternative. Additionally, the ACAM Summary report and GHG Report must be included in the document’s appendices for documentation of the air quality impact analysis. All Detail reports may be incorporated by reference and are not required to be in the appendices. However, if the Detail reports are incorporated by reference, the contractor shall ensure they are readily accessible for review by requesting parties.

· When General Conformity applies (40 CFR 93 subpart B), provide an overview of each applicable State Implementation Plan (SIP), and the purpose and requirements of General Conformity.

· A discussion regarding insignificance indicators vs. conformity thresholds should also be present in the body of the document and why thresholds or indicators are relevant for the proposed action (refer to 40 CFR 93.153 and the most recent Air Force Air Quality Environmental Impact Analysis Process (EIAP) Guide available at AQhelp.com. \

· A discussion of GHGs and Climate Change as presented in the ACAM GHG Report and outlined in the AF Air Quality EIAP Guide.

· A conclusion on the potential impact to air quality and the significance of the air quality impact for proposed actions (preferred and alternative actions). Additionally, for actions occurring within nonattainment/maintenance areas, a General Conformity Timeline Sensitivity Analysis discussion for the preferred action must be included.

For DAF EIAP, it is critical that the environmental impact methodologies for both Noise and Air Quality effects presented in the SEA are consistent to ensure technical sufficiency and reduce legal vulnerability for those actions evaluated changes in DAF operational activities. Analysis should utilize and present effects that are derived from the same site-specific operational data. Both analyses of Noise and Air Quality factor in the number and type of operations, location specific landing and take-off patterns, aircraft power settings, and other relevant details of the affected environment, the Proposed Action(s), and alternatives necessary to produce a consistent determination of environmental consequences and anticipated mitigations. The Air Quality effects analysis at the locations evaluated in the SEA must consistently assess weighted times in each mode (TIMs) of flight operations, that occur at or below the applicable mixing layer, based on the site-specific flight profiles developed for the Noise impacts analysis, the projected frequency of use of each flight profile, and the percent thrust for the various modes of operation documented in the flight profiles. See SOW Section 7.2 for Noise analysis instructions.

Section 7.2 – Noise For noise analysis, the Contractor shall adhere to the following requirements and guidance: 32 CFR 989; DoDI's 3030.2, 3030.3, 4165.57, 4715.13; AFI 32-1015; and AFH 32-7084. In general, this includes assessment of airspace and airfield activity and engine run-ups modeled in Noisemap (a suite of software including BaseOps, Noisemap, Rotorcraft Noise Model (RNM), Military Operating Area and Range Noise Model (MR_NMAP), and the Air Gunnery Model (AGM)), or the Advanced Acoustic Model (AAM) as directed in the Department of Defense (DoD) memorandum Adopting the Advanced Acoustic Model for Assessing Community Exposure to Fixed-wing Aircraft Noise (November 2022). PCBOOM and/or BOOMAP should be used to assess sonic boom exposure, if applicable. The DAF has adopted Army Regulation AR 200-1 for noise assessment of small arms and large caliber weapons, which stipulates use of Small Arms Range Noise Assessment Model (SARNAM) and Blast Noise Impact Assessment (BNOISE2), respectively.

The Day-Night Level (DNL or Ldn) is the approved noise metric for AF policy determinations, significance criteria and land-use planning. Community Noise Equivalent Level (CNEL) may also be referenced, as appropriate. Noise contours should be depicted for DNL 65, 70, 75, 80 and 85 (DoDI 4165.57 and AFI 32-1015). Some analysis may require evaluation of noise exposure below DNL 65. Guidance for use of supplemental noise metrics is provided in the 2009 DNWG Technical Bulletin "Using Supplemental Noise Metrics and Analysis Tools."

The AF-approved noise models for fixed-wing aircraft and rotorcraft are Noisemap, RNM and AAM, respectively. Contractors conducting analysis utilizing distribution-limited software and datasets should demonstrate competency and provide evidence from approving release authority for use of the respective software and/or dataset(s).

The Contractor shall use government furnished information to develop baseline noise levels, and interview appropriate Installation Personnel to collect operational data required for input into NOISEMAP and other applicable noise modelling programs. The contractor will outline the plan for noise-modelling of the proposal and ensure Government concurrence at the kick-off meeting. Operational data shall be used to develop noise contours for the airspaces and ranges of interest. The Government will arrange interview times for Installation Personnel if required. The Contractor shall collect all necessary aircraft flight and operations data needed to produce noise contours and supersonic operations analysis. The Contractor shall use a breakdown of percent time in mode/power setting for all altitude blocks for each AFB-based aircraft in the noise analysis, based on information gathered from interviews with AF pilots. The Contractor shall ensure the data utilized for the air quality analysis and noise analysis remains consistent.

For DAF EIAP, it is critical that the environmental impact methodologies for both Noise and Air Quality effects presented in the SEA are consistent to ensure technical sufficiency and reduce legal vulnerability for those actions evaluated changes in DAF operational activities. Analysis should utilize and present effects that are derived from the same site-specific operational data. Both analyses of Noise and Air Quality factor in the number and type of operations, location specific landing and take-off patterns, aircraft power settings, and other relevant details of the affected environment, the Proposed Action(s), and alternatives necessary to produce a consistent determination of environmental consequences and anticipated mitigations. The Air Quality effects analysis at the locations evaluated in the SEA must consistently assess weighted times in each mode (TIMs) of flight operations, that occur at or below the applicable mixing layer, based on the site-specific flight profiles developed for the Noise impacts analysis, the projected frequency of use of each flight profile, and the percent thrust for the various modes of operation documented in the flight profiles. See SOW Section 7.1 for Air Quality analysis instructions.

Task 8 – Noise Analysis & Deliverables At a minimum, the Contractor shall provide analyses of noise associated with the following scenarios at Hill AFB that may be affected by the Proposed Action or Alternatives at each installation:

· No Action Alternative

· Proposed Action Alternative

The above-mentioned scenarios should be analyzed in compliance with 32 CFR 989 and AFI 32-1015, Integrated Installation Planning.

For Deliverables repeated in SOW Sections 7.2.1, 7.2.2, 7.2.3, etc. below, such as the Post Data Collection & Data Validation Package and Noise Contours & Modeling Files, the Contractor shall provide a single Deliverable for each project containing information for each type of noise analysis.

Section 7.2.1 – Construction Noise Analysis Existing Conditions & Noise Analysis of No Action Alternative An analysis shall be conducted to describe the existing conditions in the study area at and around the proposed construction site. The analysis shall include both the background (ambient) noise and noise from identifiable noise sources, if any. At a minimum, the analysis shall provide average noise levels for particular groups (or clusters) of similar noise-sensitive receptors with approximately uniform noise, as well as a range of the measured noise levels for each cluster. Identifiable noise sources affecting existing noise levels in the study area shall be specified and described.

The Contractor shall conduct a noise analysis for the No Action Alternative. Under the No Action Alternative, construction of the proposed project would not occur, and no related construction noise would be generated at the site. In general, analysis of the No Action Alternative for construction projects is limited to the evaluation of other major contributors to ambient noise in the study area. The Contractor shall collect pertinent information about major contributors to noise in the study area (aircraft operations, traffic, etc.) and their potential future development, and evaluate their effect on noise levels in the study area for the design year (of the Proposed Action).

Construction Noise Impact Criteria The Contractor shall define and/or develop criteria for assessing construction noise impacts for the project. No standardized criteria have been developed at a Federal or State level for that purpose. Consequently, criteria shall be developed on a project-specific basis when local ordinances are not found to apply. Local noise ordinances typically relate to nuisance and hours of allowed activities but may not be practical for assessing the impact of a major construction project. Project construction noise criteria should consider the existing noise environment, the absolute noise levels during construction activities, the duration of the construction, and the adjacent land use. An acceptable impact threshold value for construction noise may be considered as a noise level when construction activities would be audible over the ambient noise but may be tolerable considering temporary nature of the disturbance. Industry guidelines (FHWA, FTA, HUD, etc.) may be consulted and evaluated regarding applicability of recommended impact thresholds to the project-specific land uses, time of day (day/night), and length of construction activities.

Construction Noise Analysis of Proposed Action & Alternatives The Contractor shall conduct analysis to assess potential noise impact resulting from the construction activities under the Proposed Action and Alternatives. Per AFI 32-7070 Section 3.2.10, in cases where construction noise is analyzed, the 2006 Federal Highway Administration (FHWA) Construction Noise Handbook should be used as a guide. For each construction phase, the Contractor shall obtain information related to construction equipment to be utilized, its distribution over the proposed construction site, schedule, and time (daytime or nighttime) of operation. Noise emission levels generated by individual pieces of construction equipment shall be obtained from reference literature sources and/or manufacturers. An appropriate methodology for the noise analysis shall be selected and described. A worst-case noise emission scenario for the loudest piece of equipment or several pieces of equipment concentrated within a small area may be assessed based on the distance between the noise sources located near the construction site boundary and the nearest off-site noise sensitive receptors. For more complex scenarios of equipment distribution over the construction site, noise modeling shall be conducted in accordance with the FHWA’s Roadway Construction Noise Model (RCNM). As a minimum, the modeling shall be conducted for the nearest noise sensitive receptors, where noise impacts would be the greatest. Other noise sensitive receptors in the study area shall be analyzed as necessary to represent areas of various degrees of noise impact, or potential areas of special concern. The predicted construction noise levels at the receptors shall be compared with the acceptable impact threshold levels specified per the paragraph above. The contractor shall provide recommendations for mitigation or measures to be implemented to minimize noise impacts associated with construction of the Proposed Action, as necessary.

Section 7.3 – Cultural Resources The Contractor shall comply with DAFMAN 32-7003 Environmental Conservation. For Section 106 of the National Historic Preservation Act of 1966, the Contractor shall consider the effects of the Proposed Action on historic properties as well as provide the Advisory Council on Historic Preservation the opportunity to comment on the proposed “undertaking” and its effects on historic properties.
