Keep the weekly neighborhood air log from public sidewalks in Commerce City (2026-07-18)

Commerce City's Adams Heights and neighboring blocks sit on the fenceline of a major refinery and a knot of highways, and residents have spent years documenting odors, flaring, and haze that official monitors summarize away. A disciplined weekly log — photos of visible emissions and haze from public sidewalks, timestamps, wind notes, odor descriptions — builds the community's evidence record. Standard: EPA ambient air quality community monitoring context; Colorado fenceline monitoring law context; SDG 3 and SDG 11. Proof: Photo set per vantage point + timestamped log Method (EPA ambient air quality community monitoring context; Colorado fenceline monitoring law context; SDG 3 and SDG 11.): 1. Walk the fixed route of public sidewalk vantage points on the fenceline blocks. 2. Photograph the skyline, any visible plume or haze, and reference landmarks from each point. 3. Record time, wind direction, temperature, and any odor character at each point. 4. Log any visible flaring events with timestamps. 5. File the photo set and log with date and GPS for each point. Done when: Photo set per vantage point + timestamped log

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.

Proof

Photo set per vantage point + timestamped log

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.
