NEPA Decarbonization Technology Analysis: Deliverable 1
Why NEPA Was Triggered — Classifying the Federal Nexus
Executive Summary
- Funding is the dominant NEPA trigger, accounting for 9,210 projects (44.4%). DOE’s grant and loan guarantee portfolio is the single largest source of decarbonization NEPA reviews.
- Land is the second-largest class, at 3,801 projects (18.3%). These are BLM and Forest Service right-of-way and special use permits for utility-scale renewables on public land.
- PMA/TVA is third, at 3,535 projects (17.1%). The federal power marketing administrations (BPA, WAPA, SEPA, SWPA) and the Tennessee Valley Authority act as project proponent for transmission and power infrastructure.
- Direct Action is fourth, at 3,181 projects (15.3%). It is driven overwhelmingly by DOE building, operating, and modifying its own facilities, including national laboratories and site operations.
- Review process profiles differ by trigger class. Categorical Exclusions are dominated by Funding (DOE’s CE authority for grants), Environmental Impact Statements skew toward Land and PMA/TVA, and Environmental Assessments show the most balanced trigger mix.
- Trigger class predicts regulatory intensity. Funding projects are overwhelmingly CEs, while Land and Permit generate proportionally more EAs and EISs, reflecting the heavier review burden that land disturbance and regulatory licensing carry relative to financial assistance.
- Technology patterns reflect nexus logic. Transmission has the highest PMA/TVA share (BPA and WAPA build and maintain federal lines); Solar and Wind split between Land (BLM right-of-way) and Funding (DOE grants); and CCS and Energy Storage skew toward Funding via DOE emerging-technology programs.

Reasons why NEPA was triggered (e.g., federal land, federal funding) for different types of projects.
Methodology
Trigger Definitions
NEPA applies whenever a federal nexus exists—but the nature of that nexus varies. We classify each project into one of eight mutually exclusive primary trigger classes using a strict priority ordering (highest to lowest). When evidence points to multiple classes, the higher-priority class wins as the primary; lower-priority matches are retained as secondary triggers.
| Trigger | Federal Nexus |
|---|---|
| Program | A programmatic EIS, land-use plan, or rulemaking umbrella covers the action — the NEPA review is at the policy or program level |
| Direct Action | The federal agency is the proposer — building, operating, or managing the project (e.g., agency construction, national laboratory operations, military facilities) |
| PMA/TVA | A federal power marketing administration (BPA, WAPA, SEPA, SWPA) or the Tennessee Valley Authority is the acting agency — building, upgrading, or maintaining federal power and transmission infrastructure |
| Property Transaction | A land exchange, disposal, or conveyance of federal property is the triggering event |
| Land | A private or state actor seeks a right-of-way, special use permit, or lease on federal land (BLM, National Forest) |
| Permit | A federal license or permit issued by a regulatory body (FERC license, FAA authorization, Section 404 dredge-and-fill) is the primary nexus |
| Funding | Federal grant, loan guarantee, or financial assistance is the trigger (DOE loan program, IRA grant, Rural Energy for America Program) |
| Unknown | NEPA is confirmed but the trigger cannot be reliably identified from available text or metadata |
All five classification tiers obey this priority ordering. Tiers 0–4 enforce it mechanically (each rule detects a single class, and the ladder settles conflicts). Tier 5—the LLM fallback—proposes both the classes and its own ranking; the pipeline reconciles that ranking to the fixed hierarchy at ingest, so every published primary follows the ordering above. The LLM’s raw verdicts are preserved verbatim in a committed adjudication record (tier5_adjudication_record.csv), and the published Tier 5 classifications can be reproduced exactly—without any LLM call—by running 03_rerun_tier5.py --from-record against that record.
Secondary triggers are stored separately in the nepa_trigger_secondary field; 1,559 projects (7.5%) have more than one trigger class detected. The overlap is dominated by a single structural pattern: 1,317 of these pair PMA/TVA with federal land—BPA and WAPA transmission and power infrastructure that also crosses BLM or National Forest land, so both the power-authority-proponent nexus and the federal-land nexus apply. The remaining 240 multi-class projects form a longer tail—most often federal land paired with a federal permit, or direct action paired with federal land—surfaced largely by the Tier 5 pass, which records a secondary trigger whenever its adjudication of a previously-uncertain project identifies a second nexus.
Workflow
The approach spends effort where it is needed. Cheap deterministic rules classify everything they can; machine-learning models take the bulk that rules cannot reach; and a carefully audited LLM pass handles only the hardest residue. Every automated judgment is gated, logged, and reproducible.
Classification Pipeline
Trigger classification runs in five tiers plus a manual-label seed. Each tier feeds into the next; a project is finalized the moment it clears a tier’s acceptance gate and is never re-processed by later tiers. This preserves precision at each level while reserving compute- intensive methods for the genuinely ambiguous cases.

Trigger Distribution Overview
Figure 2 shows the total number of decarbonization projects in each primary trigger class. Funding is by far the largest class: DOE’s grant and loan guarantee portfolio generates more NEPA reviews than any other federal nexus. Land is second, reflecting utility-scale renewables sited on BLM and National Forest lands under right-of-way or special use permits. PMA/TVA is third, as the federal power marketing administrations (BPA, WAPA) and TVA build and operate transmission and generation infrastructure directly. Direct Action is fourth, driven almost entirely by DOE actions at its own facilities, including national laboratories and site operations.
Permit, Program, and Property Transaction together account for 915 projects (4.4%)— these are real but narrow categories of federal nexus.
Trigger Type by Review Process
How triggers distribute across CE, EA, and EIS
Figure 3 shows what share of each review process is driven by each trigger class. The three processes reveal distinct trigger profiles:
- Categorical Exclusions are dominated by Funding—DOE’s clean energy grant and loan programs generate a high volume of low-complexity actions that qualify for CE-level review.
- Environmental Assessments show a more balanced mix: Land (BLM/USFS right-of-way grants for solar and wind) and PMA/TVA (federal transmission projects) each contribute meaningfully alongside Funding.
- Environmental Impact Statements skew heavily toward Land, PMA/TVA, and Permit—larger, more complex projects requiring full EIS review tend to be sited on public lands, be federally constructed transmission, or carry FERC licensing.
- Unknowns are now a small residual across all three processes (0.4% of the portfolio overall). The Tier 5 LLM pass resolved most of the previously-large EA and EIS uncertain pools; the unknowns that remain—still modestly more common in EAs and EISs than in CEs—are the long-document cases where neither Tier 4 nor the LLM found decisive trigger evidence.
Typical review pathway by trigger class
Figure 4 inverts the view: for each trigger class, it shows the share of projects that went through CE, EA, or EIS review. This reveals the typical regulatory pathway associated with each nexus type.
- Funding is overwhelmingly resolved at the CE level—consistent with DOE’s categorical exclusion authority for grants and financial assistance that don’t individually require significant analysis.
- Direct Action, Property Transaction, and PMA/TVA are likewise overwhelmingly CE-level reviews, owing to the routine, transactional nature of these actions—facility maintenance, conveyances, and line upgrades that require less rigorous review.
- Land, Program, and Permit produce substantially more EAs and EISs per project than Funding, Direct Action, and Property Transaction, reflecting the environmental scrutiny attached to land disturbance, programming, and regulatory licensing.
Multi-Label Structure: Secondary Triggers
Every project receives one primary trigger — the highest-priority federal nexus the hierarchy resolves — but 1,559 projects (7.5%) carry at least one secondary trigger, a second nexus the pipeline detected but ranked below the primary. These secondary labels are stored in nepa_trigger_secondary; this section cross-tabulates them to show which nexuses co-occur and where multi-label projects concentrate.
Which trigger classes co-occur
Figure 5 pairs each multi-label project’s primary trigger (rows) against its secondary trigger(s) (columns). The structure is overwhelmingly dominated by a single pattern.
1,310 of the 1,559 multi-label projects (84.0%) share the same combination — PMA/TVA + Land: BPA and WAPA transmission and power infrastructure that also crosses BLM or National Forest land, so the power-authority-proponent nexus and the federal-land nexus both apply. Every other combination is a long tail; the next-largest, Land + Permit (111 projects), is roughly a twelfth the size.
| Trigger Combination | Projects | Share of Multi-Label | Share of Portfolio |
|---|---|---|---|
| PMA/TVA + Land | 1,310 | 84.0% | 6.3% |
| Land + Permit | 111 | 7.1% | 0.5% |
| Direct Action + Land | 34 | 2.2% | 0.2% |
| Permit + Funding | 21 | 1.3% | 0.1% |
| Direct Action + Permit | 16 | 1.0% | 0.1% |
| Direct Action + Funding | 10 | 0.6% | 0.0% |
| Land + Funding | 8 | 0.5% | 0.0% |
| PMA/TVA + Land + Permit | 7 | 0.4% | 0.0% |
Where multi-label projects concentrate
Multi-label projects are not spread evenly. Figure 6 shows the share carrying a secondary trigger by review process and by energy technology.
- Multi-label rates rise with review depth. EISs carry a secondary trigger 18.2% of the time (EIS), against 7.0% for CEs — the larger, more complex projects that warrant a full EIS are precisely the ones likely to implicate more than one federal nexus.
- Transmission dominates. 21.1% of transmission projects are multi-label — more than double any other technology — reflecting the PMA/TVA-plus-federal-land pattern that drives the entire overlap. Offshore wind and hydropower follow at roughly 10%, both siting-heavy technologies that routinely touch a second nexus.
Trigger Class × Review Status
The natural next question is how trigger class interacts with the kind of NEPA review a project received. The review-type axis — CE vs. EA vs. EIS — is covered in Trigger Type by Review Process above. This section addresses the programmatic vs. tiered dimension: whether a review stands alone or tiers from an umbrella programmatic document.
A portfolio-wide programmatic/tiered classifier does not exist in Phase 2. D2’s outputs (significance determinations, regulatory regimes) do not carry a programmatic/tiered flag. The only committed programmatic/tiered signal is D6’s FONSI-enrichment is_tiered / tiers_from field, which is populated for the FONSI-enriched subset. The cross-tab below uses that source and is scoped accordingly; a full-portfolio tiering classifier remains deferred (see Coverage & Limitations).
Programmatic tiering by trigger class
Among the 452 FONSI-enriched decarbonization projects, D6 makes an explicit tiering determination for 75; 52 of those tier from a programmatic document. Figure 7 shows how those determinations split across trigger classes.
| Trigger Class | Tiered | Standalone | Undetermined | Tiered Share (of determined) |
|---|---|---|---|---|
| Land | 23 | 13 | 117 | 64% |
| PMA/TVA | 9 | 5 | 93 | 64% |
| Funding | 7 | 3 | 92 | 70% |
| Program | 7 | 0 | 16 | 100% |
| Direct Action | 3 | 0 | 28 | 100% |
| Unknown | 2 | 1 | 17 | 67% |
| Permit | 1 | 1 | 12 | 50% |
| Property Transaction | 0 | 0 | 2 | — |
Land-nexus reviews are the ones that tier. Land is both the most common determined class (36 FONSIs) and the most frequently tiered — 23 of its 36 determined reviews tier from a programmatic document, overwhelmingly BLM’s vegetation-treatment and herbicide PEISs. PMA/TVA and Funding follow. The pattern is intuitive: tiering is a public-lands management device, so it concentrates in exactly the trigger classes tied to BLM and Forest Service land. This is a FONSI-subset signal, not a portfolio rate, and should be read as directional.
Regulatory review regime by trigger class
For portfolio-scale context, D2’s project_regime output assigns each EA/EIS project a regulatory regime keyed to the CEQ rule in force at its decision date. The table below cross-tabulates trigger class against that regime for the 1,326 EA/EIS projects with a regime assignment. This is a regulatory-vintage axis, distinct from the programmatic/tiered question above.
| Trigger Class | EA/EIS Projects | Pre-2020 CEQ | 2020–2025 CEQ Rules | Undated | FRA Overlay |
|---|---|---|---|---|---|
| Land | 528 | 258 | 82 | 188 | 31 |
| PMA/TVA | 262 | 111 | 32 | 119 | 11 |
| Permit | 147 | 32 | 8 | 107 | 7 |
| Funding | 138 | 88 | 19 | 31 | 16 |
| Direct Action | 94 | 48 | 11 | 35 | 3 |
| Program | 92 | 43 | 5 | 44 | 2 |
| Unknown | 54 | 26 | 5 | 23 | 5 |
| Property Transaction | 11 | 7 | 0 | 4 | 0 |
Land and PMA/TVA supply the largest EA/EIS caseloads, and both skew toward the pre-2020 CEQ regime — the bulk of these public-lands and transmission reviews predate the 2020–2025 rule churn. Roughly two in five of the regime universe is undated (no reliable decision date recovered), so these counts are lower bounds on each vintage.
Trigger Distribution by Federal Department
Figure 8 shows trigger class distribution across federal departments—the parent cabinet agencies that house the lead agency for each project. Using department rather than individual agency names collapses the ~18+ distinct agencies into a legible set of ~8 entities.
The heatmap reads row by row: each row sums to 100%, showing how a given department’s projects are distributed across trigger classes. For example:
- Department of Energy projects are largely Funding—DOE’s primary mechanism for decarbonization investment is grant and loan programs—with sizable PMA/TVA and Direct Action shares from the power marketing administrations housed within DOE and from DOE’s own facility and laboratory actions.
- Department of the Interior (primarily BLM) projects skew toward Land, as expected given BLM’s public land jurisdiction.
- Department of Agriculture (Forest Service) mirrors Interior but at smaller scale— National Forest special use permits for biomass, wind, and transmission lines.
Trigger Distribution by Energy Technology
Figure 9 shows trigger mix across primary clean energy technology types, filtered to technologies with at least 50 projects. Technology assignment uses the first matching clean-energy NEPATEC tag per project (e.g., a project tagged Solar + Utilities is assigned to Solar).
- Solar and Wind (Onshore) projects are driven mainly by Land and Funding—utility-scale renewables either sit on BLM land or receive DOE financial assistance.
- Transmission shows the highest PMA/TVA share, consistent with the Power Marketing Administrations (BPA, WAPA) building and maintaining federal transmission infrastructure.
- Nuclear Technology shows the highest Direct Action share—DOE national laboratory and site actions dominate this category.
- Hydropower shows a distinctive mix of PMA/TVA (federal hydropower and transmission operations) and Permit (FERC licensing for non-federal hydro) alongside Funding.
- Carbon Capture & Storage and Energy Storage skew toward Funding, reflecting DOE’s active grant program for emerging technologies.
Federal Funding Deep Dive
The 9,210 Funding-primary projects (44.4% of the portfolio) warrant closer examination of how federal money flows and how much each mechanism typically awards. The figures below use a funding details sidecar produced by the funding mechanism extractor.
Funding Mechanism Types
Figure 10 breaks down Funding-primary projects by the type of federal financial instrument: grant, loan guarantee, cooperative agreement, cost-share, etc. This reveals the dominant instruments DOE and other agencies use to trigger NEPA review.
Funding Program Labels
Figure 11 shows which named federal programs and legislative authorities appear most frequently across Funding-primary projects. Program labels are multi-label — a single project may be linked to multiple programs (e.g., an IRA grant administered under the DOE LPO). Percentages are denominated by all Funding-primary projects.
Dollar Amount Coverage and Distribution
Figure 12 shows what share of Funding-primary projects have each dollar-amount field successfully extracted. Coverage varies by field type: the federal award amount is most frequently present; recipient cost share and funding percentage require more detailed document language.
Figure 13 complements the coverage view with the actual dollar distribution per mechanism type. A note on coverage: dollar amounts are extracted only when the document text contains an explicit award figure — most NEPA documents do not. As a result, only a fraction of the 9,210 Funding-primary projects have an extracted amount; the caption reports the exact count. Despite the limited coverage, the distributions are informative about typical award sizes within each mechanism type. Figure 13 focuses on common grant-scale mechanisms, excludes classes with fewer than 10 extracted amounts, and top-codes large grant-scale awards at $5 million so the main distribution remains legible. The larger loan guarantee and cooperative agreement records are shown separately in Table 5.

Geographic Distribution
State-Level Dominant Trigger
Figure 14 shows the dominant trigger class in each state — the trigger type with the most projects in that state. The map captures broad regional patterns:
- Funding dominates most states, consistent with DOE’s nationwide grant footprint.
- Land dominates in the intermountain West (Nevada, Utah, Wyoming, Montana, Arizona, and New Mexico)—states with high proportions of BLM land and active solar and wind development.
- PMA/TVA dominates states with significant federal power authority infrastructure— Washington and Oregon (BPA) and Colorado and Nebraska (WAPA).
- Direct Action dominates Idaho, West Virginia, and South Carolina—states anchored by DOE national laboratories and site operations (INL, NETL, Savannah River).
Note that dominant trigger is determined by project count, not by area or capacity. A state where a single large BLM wind project is the only decarbonization project will appear as Land even if a dozen smaller DOE-funded projects are present.
County-Level Dominant Trigger
Figure 15 disaggregates the state-level map to the county level, revealing more fine-grained geographic patterns in trigger type. Counties are colored by the dominant trigger class among all decarbonization projects located in that county.
- The Funding / Land boundary maps closely onto federal land ownership: counties spanning BLM or National Forest land (interior West) show Land as dominant; counties without substantial federal land show Funding.
- PMA/TVA clusters in counties with federal power authority infrastructure—Pacific Northwest corridors (BPA transmission), parts of the Midwest, and Southwest transmission hubs.
- Many rural counties host only one or two projects and are therefore colored by a single project’s trigger type; interpret sparse interior counties with caution.

Reproducibility
Every number and figure in this report is regenerated by committed code, run from the repository root. The one billable step — the Tier 5 LLM fallback — never needs to be repeated: its raw verdicts are frozen in a committed adjudication record, and the record replay reproduces the published classifications exactly, with no API call.
# 1. Full trigger classification, tiers 0–4 (deterministic*, no API key)
conda run -n nepa python phase2/code/deliverable01/01_extract_nepa_trigger.py
# 2. Tier 5 — EXACT replication of the published classifications from the
# committed record (deterministic, no API key, no cost)
conda run -n nepa python phase2/code/deliverable01/03_rerun_tier5.py \
--from-record phase2/code/deliverable01/tier5_adjudication_record.csv
# (alternative: statistical replication by re-running the LLM live —
# ~$2 at claude-haiku-4-5 pricing; results equivalent in aggregate
# but not guaranteed row-for-row)

# 5. This report
quarto render phase2/reports/deliverable01.qmd* Tiers 0–3 are exactly deterministic. Tiers 3b/4 run neural inference on Apple MPS without a pinned seed and can drift by a few borderline projects between machines or runs (measured: 1 project between the May and July 2026 runs); any such project enters the Tier 5 queue, where the committed record pins its published classification. See the Coverage & Limitations page and the architecture doc for the full reproducibility discussion.
