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

### This submittal addresses the December 3, 2010 amend ment as well as the amendments of June 4, 2010 and July 9, 2010.
The December 3, 2010 amendment has four key element s; (1) exempting artist solvents and thinners that are properly labeled and sold in containers that are on e liter or less from applicable VOC limits; (2) def ining artist solvents and thinners; (3) making changes to the ru le to clarify that all exempt products shall be sub ject to recordkeeping and reporting requirements; and (4) m aking changes to the rule to clarify that the sell- through provisions for the final VOC limit do not apply to products that do not meet the interim VOC limit. T he purpose
for the artist solvents and thinners is due to the artist industry not having current low-VOC products available. In addition, AQMD staff crafted the artist exemptio n and definition to be as consistent as possible wi th the Artist’s Solvent/Thinner language in CARB’s Consume r Products Regulation. This amendment will forego 114 pounds of VOC emissions per day, which is 0.6% of t he original composite VOC reduction that was claime d for the March 6, 2009 adoption date, when the rule is fully implemented on January 1, 2012.

The June 4, 2010 amendment rescinded the final limi t of 25 g/L VOC to comply with a court order. The July 9, 2010 amendment addressed the court order by incorpo rating additional labeling, education and outreach efforts to increase awareness of potential flammabi lity issues associated with reformulated solvents a nd thinners. The July 9, 2010 amendment also included administrative corrections to improve rule clarity and also added a provision to allow for the products ma nufactured prior to July 9, 2010 and labeled for mo re than one use including industrial maintenance coating th inning to be sold, used, supplied or offered for sa le up to April 1, 2011.

Future Year Control Profile Estimate (Provide information on as many years as possible) : 

### This rule is expected to reduce VOC emissions by 95 % by 2012. The interim limit of 300 g/L VOC is cur rently in effect; it became effective on January 1, 2010 a nd is expected to result in a reduction of 5.94 tpd of VOC emissions. The final limit of 25 g/L VOC in Rule 1 143 was rescinded on June 4, 2010 to comply with a court order. The final limit was to be implemented on Ja nuary 1, 2011 and was to result in 3.81 tpd of VOC emissions reduction by January 1, 2012. The final limit of 25 g/L VOC was re-adopted on July 9, 2010 thus restoring the 3.81 tons per day VOC emissions foreg one. The final limit of 25 g/L VOC will become eff ective on January 1, 2011, and is expected to yield 3.81 t pd of VOC reductions by January 1, 2012. However, the artist exemption was adopted on December 3, 2010 an d will result in 0.057 tpd of VOC emissions foregon e. The 0.057 tpd of VOC emissions foregone from Artist Solvents/Thinners combined with the 3.81 tpd VOC

emission reductions for the final limit will result in a revised final limit reduction of 3.75 tpd of VOC emissions. The composite VOC emissions reduction for this rule , when fully implemented on January 1, 2012, will b e 9.69 tpd.

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment – 

### emissions foregone

Discussion:

The proposed amendment will result in 114 pounds per day (0.057 tons per day) of VOC emissions foregone, which equates to approximately 18.5 gallons per day. The total VOC emission reduc tions applied to Rule 1143 amount to a reduction of 9.75 tons per day by January 1, 2012. Because the curre nt proposal will result in foregoing 0.057 tons per da y of VOC emissions, the total VOC emission reductio ns applied to Rule 1143 will be revised to 9.69 tons p er day. The VOC emissions foregone represent 0.6% of the total existing VOC emission reductions applied to R ule 1143.

VII. SUPPLEMENTAL CALCULATIONS

March 6, 2009 adoption of Rule 1143 – Consumer Pain t Thinners & Multi-Purpose Solvents.

• Interim VOC limit-effective January 1, 2010 will yi eld a reduction of 5.94 tpd of VOC emissions by Jan uary 1, 2011.

• Final VOC limit-effective January 1, 2011 will yiel d a reduction of 3.81 tpd of VOC emissions by Janua ry 1, 2012.

June 4, 2010 amendment to Rule 1143 - the final 25 g/L VOC limit rescinded.

• Interim VOC limit-in effect and will yield a reduct ion of 5.94 tpd of VOC emissions by January 1, 2011

.

• Final VOC limit-rescinded on June 4, 2010 and will result in 3.81 tpd of VOC emissions foregone.

July 9, 2010 amendment to Rule 1143 - readoption of the final 25 g/L VOC limit.

• Interim VOC limit-in effect and will yield a reduct ion of 5.94 tpd of VOC emissions by January 1, 2011

.

• Final VOC limit-readopted on July 9, 2010 and will result in a reduction of 3.81 tpd of VOC emissions by January

1, 2012.

December 3, 2010 amendment to Rule 1143 - adopting the Artist Solvents and Thinners exemption

• CARB 2006 Consumer and Commercial Products Survey s tatistics revealed the VOC emissions contribution f or
artist solvents and thinners to be 252.7 pounds per day for the state of California.

• SCAQMD determines VOC emissions to be 45% of the st atewide emissions inventory; thus

252.7 lbs/day * 0.45 = 113.7 lbs/day; and

113.7 * 1 ton /2000 lbs = 0.057 tons per day (tpd) of emissions foregone

• Rule 1143 Interim limit (300 g/L) will result in a VOC emissions reduction of 5.94 tpd by January 1, 2 011.

• Rule 1143 final limit will (25 g/L) will result in a VOC emissions reduction of 3.81 tpd by January 1, 2012.

• Composite VOC emissions reduction will be 9.75 tpd by January 1, 2012.- 4 - 12/03/10 CALIFORNIA AIR RESOURCES BOARD

Factoring in the emissions foregone for the Artist Solvents and Thinners exemption:

• Emissions foregone for this amendment will be 0.057 tpd

• The revised composite VOC emissions reduction appli ed to Rule 1143 is determined by subtracting the 0. 057 tpd

of emissions foregone for this amendment from the i nitial composite VOC emissions reduction of 9.75 tp d. The

difference is a revised composite VOC emissions red uction of 9.69 tpd by January 1, 2012.

• The amendments to Rule 1143 will result in an incre ase of 0.62% of VOC emissions foregone; hence

(9.75 tpd – 9.69 tpd)/9.75 tpd = 0.0062*100% = 0.6 2% increase in VOC emissions.
