Keep a weekly metal-district air diary from public sidewalks in Paramount (2026-07-18)

Paramount's neighborhoods border a cluster of metal-processing businesses whose emissions drew state and air-district enforcement after hexavalent chromium was measured in residential air. A steady weekly diary from fixed public points — odor, metallic dust on surfaces, visible plumes, public sensor readings — keeps community documentation alive between agency visits. Standard: South Coast AQMD Paramount air toxics monitoring history (AB 617 community); SDG 3 (Good Health and Well-being). Proof: Weekly diary sheet with fixed-point photos Method (South Coast AQMD Paramount air toxics monitoring history (AB 617 community); SDG 3 (Good Health and Well-being).): 1. Observe from the same two public sidewalk points at the fence-adjacent block edges at the same hour weekly. 2. Note odor character, any visible emissions or dust films on parked cars, wind direction, and the nearest public sensor reading. 3. Log everything on one diary sheet per visit and file an AQMD complaint for strong events. 4. Track week-over-week changes in the running file. 5. Photograph the view from each point and the sheet with date and GPS. Done when: Weekly diary sheet with fixed-point 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.
