# Reduction Strategies Currently Underway • Klamath County revised their Clean Air Ordinance (August 2007):

– Revised woodstove curtailment levels – Required removal of uncertified woodstove upon sale of home – Open burn – 2 periods,15 day windows - AQZ – Tightened enforcement 

# • DEQ and Klamath C ounty formed a science and technical advisory committee (January 2008)

# 8 Air Quality Program 

# Advisory Committee Report • Should: – identify the existing situation in 2008 – identify and quantify existing strategies – identify and quantify new strategies – Identify strategies that should be implemented should Klamath Falls not meet the Dec 2014 deadline



# Air Quality Program 

# Timeline – What has occurred, what is expected, deadlines

EPA revises PM2.5 standard EPA formally designates Klamath Falls as nonattainment (and establishes boundary) Attainment plan due to EPA Klamath Falls must show compliance with standard KAQSTAC – technical committee

Monitoring data to determine compliance 

### Advisory committee

Advisory committee report finalized DEQ plan development and public hearings
