Keep a weekly truck-corridor air diary from public sidewalks along Atlantic Avenue in Bell (2026-07-18)

Bell's residential blocks sit between the 710 freeway and the Atlantic Avenue truck route that feeds Vernon's industrial district, and residents breathe the diesel from both. A consistent weekly diary — timed truck counts, idle observations, dust and odor notes, nearest public sensor readings — from fixed public vantage points builds the record this small city can take to the air district. Standard: South Coast AQMD AB 617 community air protection practice; SDG 3 (Good Health and Well-being). Proof: Weekly two-point diary with corridor photos Method (South Coast AQMD AB 617 community air protection practice; SDG 3 (Good Health and Well-being).): 1. Observe from the same two public sidewalk points on Atlantic Ave at the same hour each week. 2. Count trucks for ten timed minutes at each point, noting idling trucks separately. 3. Record dust, visible exhaust, odor, wind, and the nearest public air-sensor reading for that hour. 4. Fill one diary sheet per visit and keep the running weekly file. 5. Photograph the corridor and the completed sheet at each point with date and GPS. Done when: Weekly two-point diary with corridor photos

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.
