
There was no exceedance of the NEPM PM2.5 Variation Advisory Goal of 25 ug/m .
3

The monthly maximum 24hr average at Barwon Water of 4 ug/m occurred on August 28 when the wind was from the direction
of Alcoa’s operations for a minimum of 1hr on the identified date.

The monthly maximum 24 hr average at Camp Wilkin of 14 ug/m3 occurred on August 10 when the wind was from the direction
of Alcoa’s operations for a minimum of 1hr on the identified date.

Alcoa’s operations.
Monitoring notes:

The PM2.5 monitoring program is a 12 month monitoring program conducted by NATA accredited contractors.

The ambient PM2.5 data at each site is reflective of dust from all ambient sources and all wind directions, not just from Alcoa’s
operations.

The highlighted cells in the table below indicate that the wind was from the direction of Alcoa’s operations for at least 1 hour of
the day. The cells not highlighted indicate the wind was not from the direction of Alcoa’s operations, and therefore the PM10
concentrations did not come from Alcoa.

The Barwon Water Forest Road Basin site is a background/control site, located to the north of Alcoa’s operations.

The Barwon Water Wind Direction segment = 210-235 degrees, the Camp Wilkin Wind Direction segment = 275-25 degrees
and the Camp Road Wind Direction segment = 290-340 degrees.
