LLM-Ready Permit Risk Detector
ECHO → RBLC → LLM
EPA ECHO 벌크 데이터, RBLC control evidence, state event records, and planned small-domain LLMs turn air-permit assumptions into an auditable pre-permit risk memo.
- ECHO facility, CAA Pipeline, FE&C, Air Emissions analysis
- Planned LLM evidence explanation, citations, and pre-permit checklist
- QLoRA-ready instruction data for 3-4B domain adaptation

What The Scores Mean
These are validation metrics for the research pipeline, not live permit approval probabilities.
EA means Enforcement Action. ROC-AUC measures how well the model ranks future enforcement-action cases above non-action cases when validation is done forward in time.
F1 balances precision and recall for extracted text labels. The split is grouped by REGISTRY_ID so records from the same facility do not leak between train and test sets.

Risk memo draft
Critical enforcement-action risk is driven by Texas petrochemical NAICS exposure, Title V/MACT/PSD/NSR program overlap, HAP/VOC pollutants, and flare/MSS terms. Check RBLC controls and TCEQ event narratives before permit assumptions are fixed.

Regulation Map
US air permit focusMajor-source operating permit
Consolidates federally enforceable air requirements, monitoring, reporting, and deviation certification for major stationary sources.
Preconstruction review
Screens new projects and modifications before construction. Major projects can require BACT or LAER, modeling, offsets, and public notice.
Hazardous air pollutant controls
Applies source-category standards for HAP emissions, including process controls, LDAR, monitoring, recordkeeping, and work-practice limits.
New source performance standards
Sets technology-based requirements for listed new, modified, or reconstructed source categories such as engines, heaters, tanks, and process units.
Control-technology precedent
EPA clearinghouse for BACT, RACT, and LAER determinations. It helps compare controls and limits used in similar permits.
Compliance and enforcement history
ECHO aggregates facilities, violations, inspections, emissions, and Clean Air Act enforcement actions used for analog risk screening.
Greenhouse-gas reporting layer
Tracks CO2e reporting and measurement, reporting, and verification assumptions. It should be handled separately from CAA criteria-pollutant risk.
Local permit and upset narratives
TCEQ, LDEQ, and other state records can reveal startup, shutdown, maintenance, flaring, and permit-revision patterns that federal data misses.

Data & API Expansion
The first model is ECHO-centered. The next research layer connects RBLC controls, EIASS bilingual alignment, GHGRP/K-ETS reporting, and permit revision sequences.
