Document winter ice-fog air conditions along South Cushman Street (2026-07-20)

Fairbanks sits in a valley that traps wood-smoke and vehicle exhaust under a temperature inversion most winters, a well-documented air quality problem for the whole city. This is a document-only observation pass, not a fix, to build a public record of conditions. Standard: EPA Clean Air Act ambient air monitoring, cold-region inversion tracking Proof: Dated photo and written log from the same public vantage point Method (EPA Clean Air Act ambient air monitoring, cold-region inversion tracking): 1. Document only, do not approach or touch any chimney, vent, or vehicle 2. Stand at a safe public sidewalk vantage point along South Cushman Street 3. Photograph the visible ice-fog and smoke density looking down the street 4. Note the time, temperature if known, and visibility conditions in a written log 5. Repeat from the same vantage point for a consistent record Done when: Dated photo and written log from the same public vantage point

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

Dated photo and written log from the same public vantage point

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 45–90 minutes. Method of record: EPA NAAQS community ambient-air screening (PM2.5)

Bring

• calibrated PM2.5 monitor
• GPS phone
• wind/weather note source
• hi-vis vest
• camera

Steps

1. 1. Choose >=3 points (near-source/roadside, mid, background); record GPS at each; stay off the roadway.
2. 2. Photograph each monitoring location.
3. 3. Log PM2.5 (ug/m3) at each point over a comparable peak period.
4. 4. Record wind direction, time, and nearby source activity (e.g., truck traffic).
5. 5. Compare readings to the NAAQS reference.
6. 6. Enter the PM2.5 logs, wind/time, source note, GPS, photos into the proof record; sign.

If it does not match the plan

• Roadside work near heavy traffic -> stay off travel lanes; hi-vis at all times.
• Near-source PM2.5 well above background and NAAQS -> flag an environmental-justice exposure concern.

What counts as done

• PM2.5 logged at >=3 points (near-source / mid / background)
• Wind direction + time recorded
• Source-activity observation recorded
• GPS waypoints + location photos

Proof is measured against these, not judged by taste.
