Day 1 — Kickoff
Hire third party. Schedule site access. Place canisters & sorbents across fenceline.

Day 1–14 — Waiting Window
Sampling period open. No real-time visibility.

Day 14 — Retrieval
Collect sampling devices. Prep chain-of-custody. Package and ship to lab.

Day 15–27 — Transit + Queue
Courier time. Lab intake. Backlog. Method setup. (No insight yet.)

Day 28 — Results Arrive
Lab report shows an exceedance. No timestamp clarity; no source localization.

Day 29 — Coordination Sprint
Internal huddle. Emails. Meetings. Compliance clock is ticking.

Day 30 — Second Round
Deploy more canisters to “hunt” the source. Start another 2-week wait.

Day 31–44 — More Waiting
Wind shifts. Conditions change. The exceedance window has passed.

Day 45 — Call in “Real-Time” Help
Bring in a separate contractor for active spot checks. Scope, PO, mobilize.

Day 48 — Parallel Sampling
New passive round begins while spot checks proceed. Data sets won’t align in time.

Day 50 — Suspected Source Identified
Confidence limited; conditions differ from exceedance day.

Day 51 — Repair Attempt
Fix performed. No immediate feedback that the repair solved it.

Day 52–59 — Verification Lag
Must wait for next passive cycle/lab to confirm. Operations on edge.

Day 60 — Ship Again
Another lab round. Another queue. More reconciliation later.

Day 74+ — Confirmation (Maybe)
If lab confirms, document and compile manually. If not, repeat the hunt.

Day 75+ — Reporting Crunch
Assemble PDFs, spreadsheets, field notes, and lab reports. QA/QC by hand. Prepare regulator-ready packet.

Day 90 — File
Submit reporting set. Begin next cycle—the loop repeats.
