RDKit-checked fuel, aqueous, emissions, nutrient, and PFAS markers tied to compliance evidence packages
Docker-Generated Compliance Gates
Compliance Gate Lab
A 3D regulatory-readiness workspace for keeping fuel specifications, air/water/solids permits, PFAS and pathogen methods, and annual GHG reporting synchronized before commercialization claims.
specification, permit, analytical, and reporting gates ranked for real deployment readiness
top current gate because separate approvals fail when assumptions are not packaged as one permit-ready dossier
selected gates spanning fuel release, air, water, solids, PFAS, and annual reporting closure
integrated permit package
Integrated permit package and regulator pre-application gate
Unify fuel, air, water, solids, PFAS, and reporting evidence into a staged regulator-facing packet.
Run joint permit-readiness review with assumptions, measurement plans, and fallback conditions made explicit.

Pyomo-formulated compliance selector with deterministic enumeration across fuel specifications, air/water/solids permits, PFAS or biosecurity methods, MRV reporting, and integrated permit package coverage. Current package covers 7 categories and 18 compliance markers.
Markers tied to this gate
n-Dodecane; Pyridine; PFOA; Methane; Nitrate; Phosphoric acid
The marker set keeps fuel-release analytes, aqueous discharge loads, PFAS indicators, and reporting-relevant gases visible in one reviewer-facing surface.

- NPDES load and toxicity closure campaign; Integrated regulator pre-application review; Title V source-boundary and monitoring architecture run
Selected gates keep product specification, air/water/solids permits, PFAS methods, and annual reporting coupled so no single pass metric can hide a compliance failure.
Current compliance decision
Conversion proof is not commercialization permission
The project can show conversion and upgrading progress while still being non-deployable. Compliance readiness requires linked evidence: fuel specifications, permit boundaries, residual and PFAS methods, biological controls, and annual GHG reporting controls that stand up under audit and regulator review.
7 compliance categories are covered by the selected package.
PFAS persistence remains visible so release and residual narratives cannot skip matrix-qualified method evidence.
Fuel-release quality checks are strong only when matched with permit and reporting controls.
Carbon and emissions claims require annual ledger closure discipline, not one-time campaign results.
