Burn ban stage 1 continues until further notice for Yakima County

Effective: 12:00 p.m. PDT today, Monday, August 5, 2012:

The Pollution Control Officer for the Yakima Regional Clean Air Agency declared a Stage 1 Burn Ban for both the Upper and Lower Yakima County areas last week, due to residual smoke originating from wildfires.

Air quality has improved over the weekend. However, the lower valley still experiencing higher concentration of fine particulates than normal (Moderate).

Because any outdoor burning in the Upper County area can adversely impact the Lower County area, the Stage 1 Burn Ban will continue until further notice in both areas. However, if conditions continue as expected, watch for us to lift the burn ban by Wednesday August 7, 2013.

·       PM2.5 Air Quality levels are into the Moderate (Yellow) level in the Lower County area, and

·       PM2.5 Air Quality levels are into the Good (Green) level for the Upper County area.

·       Agricultural Burn allocation are 0  piles per request for Upper and 0 for the Lower Today.

·       Dispersion for our jurisdiction is Poor to Poor.

·       Ventilation for our jurisdiction is Poor to Poor.

·       Wind speed  ~ North to Northwest at 6 mph, increasing to 10 mph at night.
