### Bruce - I have been contacting the CA Air Districts about their adoption of the 2007 SCM -

can you let me know if your considering adopting this year. Also and could you please add

me to your AIM stakeholder list. Finally, the coatings industry is under constant pressure to

reformulate products to lower and lower VOC content. As a result there is a critical and

urgent need for safe, effective and affordable exempt solvents and coating formulators need

all available tools to formulate both lower VOC and reactivity coatings. The American

Coatings Association requests that TBAC, Dimethyl Carbonate (DMC) and Propylene

Carbonate be added to the list of exempt compounds in your District. These compounds

were exempted by the US EPA based on their negligible contribution to tropospheric ozone

formation.

### Bruce - it was a pleasure speaking with you at the works hop - here are the two additional comments I promised:

1. Early compliance option - several of the new niche categories are ne eded now - so we were able to convince

the other Air Districts to allow the sa le of products prior to the compliance date as long as the products met the

new limits - here is the language from the San Joaquin rule:

5.8 Prior to January 1, 2011, any coating that meets a defi nition in Section 3.0 for a co ating category listed in

the Table of Standards 2 and complie s with the applicable VOC limit in the Table of Standards 2 and with

Sections 5.2 and 6.1 (including those provision of Secti on 6.1 otherwise effective on January 1, 2011) shall be

considered in compliance with this rule.

2. Specialty Primer labelin g transition language - since the Specialty primer labeling requirements change -

we were able to convince the other Ai r Districts to include tr ansitional language in the rules - here is language

from San Joaquin:

6.1.8 Specialty Primers, Sealers and Undercoaters: Eff ective until December 31, 2010, the labels of all specialty

primers, sealers and undercoaters shall prominently display one or more of the descriptions listed in

Section 6.1.8.1 through 6.1.8.5. Effective on and after Janua ry 1, 2011, the labels of all specialty primers,

sealers, and undercoaters shall prominently display one or more of the descriptions listed in Sections

6.1.8.1 through 6.1.8.3. On and after January 1, 2011, Sections 6.1.8.4 and 6.1.8.5 will b e no longe r

effective.

6.1.8.1 For fire-damaged substrates.2 

### 6.1.8.2 For smoke-damaged substrates.

6.1.8.3 For water-damaged substrates.

6.1.8.4 For excessively chalky substrates.

6.1.8.5 For blocking stains

Please let me know if you have any questions,

Coating

Bruce - I did receive the following minor comments, I am waiting for another member - I hope to hear

back tomorrow

1. Transitional paragraph after the table of standards (for clarity):

Effective July 1, 2011, the following coating categories in the Table of Standards 1 are

eliminated, and these coatings will be subject to the VOC limit for the applicable

category in the Table of Standards 2, except as provided in Sections 302 and 303:

2. Also, it seems that Rust Preventative Coatings and Specialty Primers are unregulated from July 1,

2011 to January 1, 2012 -- no limit is given in the Table 2 column effective July 1, just the final limit in

the column effective January 1. The limit in the previous Table 1 would no longer apply, since that

table is labeled "Effective until July 1, 2011." This can be corrected by inserting the current limits into

the Table 2 column effective July 1, 2011.

3. Section 303 -- Sell-through of Coatings -- should be revised to delete the parenthetic reference to

Table of Standards 1 (because "standards in effect at the time the coating was manufactured" may be

found either in Table 1 or in Table 2).

Bruce - just checking in on the AIM rule - last time we communicated your were going to set the compliance dateat 7/1/11 for all categories except Primer, Sealer, Undercoaters (PSUs) and Rust Preventatives - which were going

to be 1/1/2012 - is this still the case? Is the Board package available for review?

### Bruce - I sent this out to my group - I asked them to get back to me by Wednesday of next

week - so far the only comment that came back was that the Rust Preventative and SPSU

limits kick in on July 1, 2011, 6 months before Jan 1, 2012 of the other Air District rules -

Bay Area, San Joaquin, Kern, Ventura and Imperial - I should have realized this at the

meeting. Could I please ask that the rust Preventative and SPSU categories limits be pushed

to 1/1/2012 to be consistent with the other Air Districts? This could be accomplished by

adding another column to Table of Standards 2 - I am sorry for any confusion
