days when air quality is forecast to be unhealthy. Limi ted exmeptions are provided for sole source of heat,

financial hardship, cooking, religious activities and gaseous fueled devices.

The rule amendments set lower thresholds for PM2. 5 concentrations used to declare No Burn days.

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

III. SOURCES/ATTAINMENT STATUS

District is: Attainment Nonattainment Split

Approximate Total Number of Small (<100 TPY) Source s Affected by this Amendment: 276,000 wood burning appliances

Percent in Nonattainment Area: 100%

Number of Large (> 100 TPY) Sources Controlled: Percent in Nonattainment Area: %

Name(s) and Location(s) (city and county) of Large (> 100 TPY) Sources Controlled by Rule (Attach additional sheets as

necessary) :

IV. EMISSION REDUCTION TECHNOLOGY

Does the Rule Include Emission Limits that are Continuous? Yes No

If Yes, Those Limits are in Section(s) of the Rule.

Other Methods in the Rule for Achieving Emission Reductions are: Section 301 of the rule prohibits burning of wood on

days where the Air Pollution Control Officer has determined that ambient PM2.5 concentra tions may exceed specified

thresholds. There is also a lower threshold at which the Ai r Pollution Control Oficer may declare a voluntary curtailment

of wood burning.

V. OTHER REQUIREMENTS

The Rule Contains:

Emission Limits in Section(s): 301 Wo rk Practice Standards in Section(s): N/A

Recordkeeping Requirements in Section(s): N/A Reporting Requirements in Section(s): 401-403CALIFORNIA AIR RESOURCES BOARD

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: Impacts attainment by r educing the emissions of particulate ma tter on days that have a high probability of

exceeding ambient air quality standards.
