The application-results summary now distinguishes the physical condensate-tank pressure-control vent from the applicant’s modelling choice to group that stream at the HP flare. The distinction is explicit in application PDF60 and its footnote. No source rates or Explorer calculations have changed.
The simulator page now includes a comparison of current and historical source cases under five fixed weather settings, across ten community reference points. The new comparison report and downloads retain the source rates, event durations, geometry and calculation code. Values are source-only air-layer means: PM₂.₅ uses a 24-hour mean, while the gases use the largest of 24 one-hour means. No background, flare plume rise or health-risk calculation has been added. The underlying simulator is unchanged.
The simulator is now the public homepage. The past open-house question guide and question sheet are no longer presented on the website; the former sheet URL redirects to the simulator. Existing research links remain available. This navigation update does not change the model, source inputs or dated research archives.
The Explorer now offers seven cases from the signed 23 October environmental protection notice (application 455458), linked to current physical source geometry in the October application. It adds SO₂ and the unburned venting constituents H₂S and total reduced sulphur. Continuous cases show a 24-hour analysis window; venting shows only the first 24 hours of a selected release up to the documented 48-hour event maximum. Source audit, modelling choices and update package.
These are proposed maximum/design inputs, not approved limits or measured releases. The Explorer holds each selected rate constant. Its assumed winds and passive transport engine are unchanged; physical tip height is not a plume-rise calculation. The historical cases and September review archive remain separately labelled. The current source update does not validate community exposure predictions.
A new exact-solution benchmark measures artificial spreading in the unchanged browser engine. The coarse grid substantially lowers the test cloud’s peak; finer spacing reduces the error. The report preserves all eight failed moment checks and explains the larger-domain controls. These findings do not provide a correction factor for local exposure. Findings and reproducible experiment.
5 September 2026 · First public hearing companion
This independent community resource was assembled with AI-assisted research, data processing and writing. It has not received qualified independent scientific review and is not affiliated with Woodfibre LNG, BCER, the District, any Nation or the researchers discussed in linked sources.
Correction, 29 September 2026: the organizer’s 15 September notice reschedules the open house from 17 September to 1 October 2026, 4:30–7:30 p.m., Executive Suites, Squamish. The former question sheet recorded this event; it is now kept outside the public site. The home page now opens the simulator. This is an open house, not described here as a statutory public hearing.
Earlier “independent” checks and reviews within this project refer to separate automated implementations or AI-agent reviews unless a named external source establishes otherwise. They are not independent human scientific peer review. No completed external scientific evaluation or institutional endorsement is claimed. Researcher review guide and runnable package.
The June 2015 startup duration is a historical preliminary-design estimate. The November update recovers current proposed source rates and physical geometry. Event time histories, consistent heat inputs and local vertical weather remain important gaps. Absence from our search is not proof that a document does not exist or was never submitted.
The browser plume solver is illustrative and has not demonstrated grid convergence. Dated monitoring samples are not live data. Forecast-versus-observation tests do not drive the browser plume. Historical flat-ground screening uses explicit 1.5 m receptors and synthetic weather; it is not a neighbourhood exposure prediction. Community overlap colours do not establish health risk, a permit breach or a safe distance.
The current B.C. objectives were checked against the province’s pollutant pages. Their statistical rules and applicable averaging periods accompany the values. SO₂ source scenarios are available in the November update. No individual benzene source scenario is available; total VOC is not benzene.
The Explorer now compares all ten existing community reference points for the selected pollutant, with a common full-day or hourly-block averaging period, benchmark percentages and explicit missing comparisons. The page adds concise health context and keeps detailed methods in expandable notes. Model physics, emission rates and saved wind fields are unchanged. The public tool supports conditional scenario exploration; benchmark flags are not illness predictions or safe-distance findings.
Two unchanged wind replays record the temperature and convective-history calculation directly. The new comparison separates preparation, override, denominator and vertical-stencil effects and retains the near-ground coverage limits. A separate archive recovery provides higher-precision temperature, pressure and humidity for one previously selected tile. Thermal study · Archive recovery. These research additions do not change the Explorer’s plume or adopt a new wind field.
New research traces the selected vertical-motion discrepancy to terrain-tangent redirection and compares the height-independent stability proxy with archived vertical profiles. Full-area support counts and printing envelopes accompany the comparison. The reports distinguish the native-AGL temperature preparation from common-absolute-height sampling, and update the profile and observation priorities. Stage trace · Stability study.
The public plume and saved-wind data are unchanged; these diagnostics do not select a new wind configuration or produce new concentration estimates. The open-house question guide remains separate.
The Explorer now includes the 14-hour LPCF tank-shutdown reconstruction, alongside the 30-minute WWGF and CDGF cases. Time controls extend to 24 hours; source captions distinguish scheduled mass from emitted mass and identify custom durations. Rates use full-precision reconstruction from the same 2014 inventory. The source comparison switches between rates and full historical event totals. Its controls display loading feedback until ready.
The transport engine and worker are unchanged. The plume still uses illustrative fixed scenario winds and a prescribed injection height; it does not use CALMET. New vertical-resolution, native-wind comparison and thermal-path reports do not support adopting new wind forcing. The saved-wind viewer remains unchanged. Inputs, timing and verification.
For any proposed correction, identify the affected question or report, provide the source document and page, its date and revision, and describe what changes. A new number should retain units, averaging period, source status and uncertainty. There is no public submission form on this edition; no comments or personal details are collected by the companion.
The research plan identifies exact acquisition routes. The record-request drafts are unsent. Nothing on this site sends a records request or hearing submission.
Research reports were converted from the working deliverables to readable web pages. Local report links were replaced by public links. Frozen archive bytes were preserved. The November source update changes the source catalogue, controls and worker source placement while retaining the passive calculation engine and existing embedded weather/geography data. Its public interface includes responsive spacing, loading and recovery feedback, keyboard navigation and automatic sizing. The publication manifest records the original file sizes and hashes; a report’s original Markdown hash is not the hash of its rendered HTML.
The public site now leads with simulations, with observations, methods and supporting research below. The past open-house question guide is retained locally. This is a static public site hosted on Fly.io. It has no account system, advertising, analytics scripts or collection form. Hosting providers may process standard connection logs. The explorer loads plotting and positioning libraries from jsDelivr and unpkg; those services receive the associated web requests. Copying a question uses the browser clipboard only when its button is pressed. Links to outside sites follow those sites’ own practices.
The map credits OpenStreetMap contributors and NRCan elevation within the explorer. Source documents retain their own authorship and terms; inclusion of a source does not imply endorsement. Research archives include unmodified official reference materials and original public data for reproducibility.
