Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

The rule amendments implement 2012 AQMP control measures BCM-01 [Further Reductions from Residential Wood-Burning Devices] and BCM-02 [Further Reductions from Open Burning]. Amendments to Rule 445 – Wood Burning Devices lower the threshold for a wintertime wood burning curtailment, establish criteria for a basin-wide curtailment, and set standards for solid-fuel labeling for wood and wood-based products by commercial firewood sellers. Amendments to Rule 444 – Open Burning incorporate the winter season burn restrictions consistent with

amended Rule 445.

Complete this section ONLY for rules that, when implemented, w ill result in quantifiable changes in emissions. Attach referenc e(s) for emission factor(s)

and other information. Attach calculation sheet showing how the emission information provided below was determined

Net Effect on Emissions: Increase* Decrease** N/A

Emission Reduction Commitment in SIP for this Source Category: Amendments to Rule 445 represent a State Implementation Plan (SIP) commitment to reduce PM emission s from wood burning devices by up to seven tons per episodic winter day by the year 2014. Amendments to Rule 444 could poten tially reduce Basin 2.5 emissions on episodic no-burn days by about 4.6 tons per winter day, however, since the open burning would likely be shifted to other days the total annual emissions would remain the same.

Baseline Inventory in the SIP for the Control Measure: 2008

Emissions Reduction Commitment in the SIP for the Cont rol Measure: Amendments to Rule 445 represent a State Implementation Plan (SIP) commitment to reduce PM emission s from wood burning devices by up to seven tons per episodic winter day by the year 2014. Amendments to Rule 444 could potentially reduce Basin 2.5 emissions on episodic no-burn days by about 4.6 tons per winter day, however, sinc e the open burning would likely be shifted to other days the

total annual emissions would remain the same.

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: SCAQMD staff has estimated that the changes to the Rule 445 mandatory burning curtailment program could potentially reduce Basin ambient PM2.5 em issions on episodic no-burn days by about 7.1 tons per winter day (presuming 75% rule effectiveness). Aligning the Rule 444 open burning restrictions with Rule 445 prov isions could potentially reduce Basin PM2.5 emissions on episodic no-burn days by about 4. 6 tons per winter day; however, since the burning would likely be shifted to other days, the total annual emissions w ould remain the same. Accordingly, no annual emissions reductions are anticipated under Rule 444 provisions for tradi tional open burning sources (agriculture/prescribed burns), but emissions reductions would be expect ed to be achieved on individual days where high PM2.5 levels are forecast, thus reducing public health impacts.
