Project Description Summary of the Effects of 

New Rule 323.1, Architectural Coatings 
Santa Barbara County APCD Rule 323.1 Project 1 May 15, 2014

PROJECT DESCRIPTION SUMMARY OF THE EFFECTS OF

NEW RULE 323.1, ARCHITECTURAL COATINGS

Project Overview:

The intent of new Rule 323.1 is to reduce volatile organic compound (VOC) emissions from

coatings used in the painting of buildings and other structures. 

The Santa Barbara County Air Pollution Control District (District) expects Rule 323.1 will

reduce VOC emissions by about 98 tons per year (TPY) in planning year 2020, thereby cleaning 

the air and allowing progress toward meeting state health standard for ozone. The estimated 98

TPY emission reduction is in addition to the emission reduction already achieved by the existing 

Rule 323.

Current Rule 323 established limits on the VOC content of architectural coatings supplied, sold, 

offered for sale, applied, solicited for application, or manufactured for use within the District.

We propose to update the architectural coatings rule requirements in a new Rule 323.11and 

ultimately phase out Rule 323. With this approach, stores can sell existing Rule 323-compliant 

coatings up to three years after Rule 323.1 becomes effective. 

Staff proposes to lower architectural coating VOC content limits for consistency with the 

California Air Resources Board Suggested Control Measure (SCM) for Architectural Coatings

(adopted October 26, 2007), which other air districts have adopted and implemented. 

Objectives:

Adoption of Rule 323.1 will fulfill emission reduction commitments the District made in the 

2010 Clean Air Plan. Once adopted, staff will submit Rule 323.1 to the California Air Resources 

Board (CARB) for inclusion into the State Implementation Plan (SIP) and to EPA for an update 

to the federal Outer Continental Shelf Air Regulations.

Introduction and Background:

CARB has designated the Santa Barbara County Air Pollution District as a moderate 

nonattainment area for the state 8-hour ozone standard. Architectural coatings are a large source 

of volatile organic compound emissions in Santa Barbara County, accounting for about 500 tons 

in 2012 (Ref. 1). Volatile organic compound emissions cause the formation of ozone and 

particulate matter less than ten microns in size, two of the pollutants of concern in Santa Barbara 

County. Rule 323.1 uses the term volatile organic compound in lieu of reactive organic 

compound for consistency with the 2007 ARB SCM. For all intents and purposes both terms 

have the same meaning.

The District originally adopted Rule 323 on October 18, 1971, to regulate volatile organic 

compound emissions from the use of architectural coatings. Since 1971, the District has amended 

 

1 Proposed new Rule 323.1 is provided as Attachment A.
Santa Barbara County APCD Rule 323.1 Project 2 May 15, 2014

the rule eight times: February 24, 1975; August 22, 1977; June 11, 1979; March 11, 1985;

February 20, 1990; March 16, 1995; July 18, 1996; and November 15, 2001. 

The amendments in 1975 through 1985 revised effective dates of technology-forcing limits and 

clarified language. The amendments in February 1990 revised the rule to be consistent with the 

1989 California Air Resources Board Suggested Control Measure. The 1995 and 1996 

amendments dealt with general rule cleanup issues and expanded the list of compounds exempt 

from the definition of volatile organic compound. The 2001 amendment incorporated the June 

2000 California Air Resources Board Suggested Control Measure VOC content limits.

Implications to the Regulated Community:

WHO IS AFFECTED?

Any person who:

1. Supplies, sells, or offers for sale any architectural coating for use within the District; or

2. Manufacturers, blends, or repackages any architectural coating for use within the District; 

or

3. Applies or solicits the application of any architectural coating within the District.

WHAT ARE THE PROPOSED RULE CHANGES?

In general, the definitions and VOC content limits are being amended to be consistent with the 

2007 ARB SCM. Attachment A shows the proposed Rule 323.1, Attachment B shows the 

differences between Rule 323 and Rule 323.1, Attachment C shows the differences between the 

2007 ARB SCM and Rule 323.1, and Attachment D is a table that summarizes the reasons for 

deviations from the 2007 ARB SCM. 

Comparisons to Adjacent Local Air Pollution Control Districts:

Air districts adjacent to the Santa Barbara County Air Pollution Control District include the San 

Joaquin Unified Valley Air Pollution Control District, the Ventura County Air Pollution Control 

District, and the San Luis Obispo County Air Pollution Control District.

The San Joaquin Unified Valley APCD and the Ventura County APCD incorporated the 2007 

ARB SCM limits into their architectural coating rules in 2009 and 2010, respectively. The San 

Luis Obispo County APCD has not amended their architectural coating rule to include the 2007 

ARB SCM provisions.
Santa Barbara County APCD Rule 323.1 Project 3 May 15, 2014

Fiscal Impacts to the Regulated Industry due to New Rule 323.1:

According to the 2007 ARB SCM, assuming manufacturers passed their cost increases for 

compliance with the SCM coating VOC limits on to consumers, the average potential increase is 

about $1.21 per gallon ($1.36/gal in 2013 dollars). Further, based on the average cost per gallon 

for consumers of $19.20 ($21.56/gal in 2013 dollars), the average increase in the cost per gallon 

would be about six percent. 1

ARB estimated that the total annualized cost of the SCM to be $12.3 million ($13.8 million/year 

in 2013 dollars). Apportioning this figure to Santa Barbara County, the total annualized cost of 

the SCM is about $250,000 ($280,000/year in 2013 dollars).

Emission Reductions, Cost Effectiveness, and Incremental Cost-Effectiveness:

WHAT ARE THE EMISSION REDUCTIONS FROM RULE 323.1?

The planning year 2020 VOC emission reduction due to the Rule 323.1 is nearly 98 TPY (about 

0.25 tons per day). This VOC emission reduction is solely from reducing the coating VOC 

content limits. This VOC emission reduction is significantly greater than the 32.4 tons per year

predicted in the 2010 Clean Air Plan for planning year 2020. 

The following table shows the projected emission reductions for this rulemaking activity. It 

should be noted that the projected future emissions also take growth into consideration.

WHAT IS THE RULE 323.1 COST EFFECTIVENESS?

The cost effectiveness of Rule 323.1 is $3,017 per ton of VOC reduced. This cost effectiveness 

figure compares favorably with the cost-effectiveness of similar regulations.

Santa Barbara County APCD Rule 323.1 Project 4 May 15, 2014

WHAT IS THE RULE 323.1 INCREMENTAL COST EFFECTIVENESS?

Incremental cost effectiveness is intended to measure the change in costs (in dollars per year)

and emissions reductions (in tons reduced per year) between two progressively more effective 

control options or technologies. For this rule project, an incremental cost effectiveness analysis 

does not apply because this rule only has one control technique: reducing VOC coating limits. 

This rule does not include another control option (e.g., use of add on control equipment). Hence, 

there is no progressively more effective control option to compare the reduced VOC limits to and 

it is not possible to perform an incremental cost effectiveness analysis.

Implications to the District Work Load and Budget:

The District anticipates the current staffing levels will be sufficient for inspections and industry 

outreach programs to implement the new rule provisions.

Public Review:

WHAT PUBLIC REVIEW PROCESS DID THE 2007 ARB SCM UNDERGO?

The California Air Resource Board commenced the public review process for the 2007 SCM 

with the formation of an industry working group in October 2006. ARB staff held three public 

workshops and meetings on December 12, 2006; March 13, 2007; and June 6, 2007. The first 

workshop focused on general discussions regarding the SCM update, the project timeline, and 

the technical approach. At the second workshop, ARB staff presented draft VOC limits and

revised definitions for several major coating categories. At the third workshop, ARB staff 

presented draft regulatory language for the entire SCM (Ref. 2).

WHAT PUBLIC REVIEW PROCESS DID THE PROPOSED NEW RULE 323.1 UNDERGO?

The District conducted a workshop on March 11, 2014. Staff met with representatives of the 

Sherwin-Williams company on March 18, 2014.

We received extensive feedback on the March 7, 2014 draft rule. The primary concerns raised 

had to do with various solvent cleaning provisions incorporated into the draft rule. Considerable 

feedback was received that these provisions deviated from the SCM and created complexities 

and hardships for compliance. After careful consideration of all input received, we removed the 

solvent cleaning provisions from the rule. 

Further rationale for this change is provided below:

1. for Rule 323, the 2010 CAP estimated about 32 TPY reductions for planning year 2020 in 

total (e.g., from both solvent cleaning and coating control techniques). The architectural 

coatings limits technique alone achieves about 98 tons/year for planning year 2020, far 

more than projected in the CAP.
Santa Barbara County APCD Rule 323.1 Project 5 May 15, 2014

2. Incorporating the CAP- identified solvent cleaning limits would present conflicts with the 

ARB Consumer Products Regulation (amended September 24, 2009). The ARB 

regulation established VOC content limits for solvents used for thinning, paint clean-up, 

and surface preparation for painting with architectural coatings.

3. As ARB is claiming reductions under their Consumer Product Regulation, the District

can no longer claim emission reductions from reducing the VOC contents in solvents 

associated with the application of architectural coatings. 

4. Eliminating solvent cleaning requirements in Rule 323.1 avoids the need to add 

numerous exemptions, solvent recordkeeping, and solvent cleaning enforcement 

procedures, which were not part of the State Suggested Control Measure. It also avoids 

hardships on small painting businesses.

Staff provided draft proposed Rule 323.1 to the Community Advisory Council (CAC) on April 

30, 2014. After hearing a staff briefing on the project on May 14, 2014, the CAC passed a 

motion to recommend that the Board approve proposed Rule 323.1.

Santa Barbara County APCD Rule 323.1 323.1 - 22 [date of rule adoption]November 15, 2001

a. With the exception of low solids coatings, determine the VOC content in grams of VOC 

per liter of coating thinned to the manufacturer’s maximum recommendation, excluding 

the volume of any water and exempt compounds. Determine the VOC content using 

equation 1 as follows:

 (Ws ̶ Ww ̶ Wec)

VOC Content = (1)

(Vm ̶ Vw ̶ Vec)

Where:

VOC Content = grams of VOC per liter of coating

Ws = weight of volatiles, in grams

Ww = weight of water, in grams

Wec = weight of exempt compounds, in grams

Vm = volume of coating, in liters

Vw = volume of water, in liters

b. For low solids coatings, determine the VOC content in units of grams of VOC per liter of 

coating thinned to the manufacturer’s maximum recommendation, including the volume 

of any water and exempt compounds. Determine the VOC content using equation 2 as 

follows:

 (Ws ̶ Ww ̶ Wec)

VOC Content

 ls = (2)

 Vm

 

Where:

VOC Contentls = the VOC content of a low solids coating in grams of VOC per liter of 

 coating

Ws = weight of volatiles, in grams

Ww = weight of water, in grams

Wec = weight of exempt compounds, in grams

Vm = volume of coating, in liters.

2. VOC Content of Coatings: To determine the physical properties of a coating in order to perform 

the calculations in G.1.a and G.1.b, the the Section C definition for VOC Actual for low solids 

coatings or the Section C definition for VOC Regulatory for all other architectural coatings, the 

reference method for VOC contentContent is United Statesthe Environmental Protection Agency 

Method 24, incorporated by reference in Section G.5.kh, except as provided in Sections G.3 and 

G.4. An alternative method to determine the VOC contentContent of coatings is South Coast Air 

Quality Management District Method 304-91 (revised February Revised 1996)), “Determination 

of Volatile Organic Compounds (VOC) in Various Materials,” incorporated by reference in 

Section G.5.k. i. The exempt compounds content shall be determined by South Coast Air Quality 

Management District Method 303-91 (Revised August 1996),1996), “Determination of Exempt 

Compounds,” or the Bay Area Air Quality Management District Method 43 (Revised 2005), 

“Determination of Volatile Methylsiloxanes in Solvent-Based Coatings, Inks, and Related 

Materials,” or the Bay Area Air Quality Management District Method 41 (Revised 2005), 

“Materials Containing Parachlorobenzotrifluoride,” as applicable, incorporated by reference in 

SectionSections G.5.j. g, G.5.e, and G.5.f, respectively. To determine the VOC contentContent of 

a coating, the manufacturer may use United Statesthe Environmental Protection Agency Method 

24, or an alternative method as provided in Section G.3, formulation data, or any other reasonable 

means for predicting that the coating has been formulated as intended (e.g., quality assurance 

checks, recordkeeping). However, if there are any inconsistencies between the results of a Method 

24 test and any other means for determining VOC contentContent, the Method 24 test results will 

govern, except when an alternative method is approved as specified in Section G.3. The Control 

Officer may require the manufacturer to conduct a Method 24 Analysisanalysis.

allowable emissions for a single compliance period that the Program will be in effect. In 

addition, the demonstration shall include VOC content information for each coating that 

is below the compliance limit in Table 1. The demonstration shall use the equation 

specified in subsection A.1 of this Appendix for projecting the actual emissions and 

allowable emissions during each compliance period. The demonstration shall also 

include all VOC content levels and projected volume sold within the State for each 

coating listed in the Program during each compliance period. The requested data can be 

summarized in a matrix form.

A.3.4 A specification of the compliance period(s) and applicable reporting dates. The length of 

the compliance period shall not be more than one year or less than six months.

A.3.5 An identification and description of all records to be made available to the Executive 

Officer upon request, if different than those identified under subsection A.3.6.

A.3.6 An identification and description of specific records to be used in calculating emissions 

for the Program and subsequent reporting, and a detailed explanation as to how those 

records will be used by the manufacturer to verify compliance with the averaging 

requirements.

A.3.7 A statement signed by a responsible party for the manufacturer, that all information 

submitted is true and correct, and that records will be made available to the Executive 

Officer upon request.

A.4 REPORTING REQUIREMENTS

A.4.1 For every single compliance period, the manufacturer shall submit a mid-term report 

listing all coatings subject to averaging during the first half of the compliance period, 

detailed analysis of the actual and allowable emissions at the end of the mid-term, and an 

explanation as to how the manufacturer intends to achieve compliance by the end of the 

compliance period. The report shall be signed by the responsible party for the 

manufacturer, attesting that all information submitted is true and correct. The mid-term 

report shall be submitted within 45 days after the midway date of the compliance period. 

A manufacturer may request, in writing, an extension of up to 14 days for submittal of the 

mid-term report.

A.4.2 Within 60 days after the end of the compliance period or upon termination of the 

Program, whichever is sooner, the manufacturer shall submit to the Executive Officer a 

report listing all coatings subject to averaging during the compliance period, providing a 

detailed demonstration of the balance between the actual and allowable emissions for the 

compliance period, any identification and description of specific records used by the 

manufacturer to verify compliance with the averaging requirement, and any other 

information requested by the Executive Officer to determine whether the manufacturer 

complied with the averaging requirements over the specified compliance period. The

report shall be signed by the responsible party for the manufacturer, attesting that all 

information submitted is true and correct, and that records will be made available to the 

Executive Officer upon request. A manufacturer may request, in writing, an extension of 

up to 30 days for submittal of the final report.

A.5 RENEWAL OF A PROGRAM

A Program automatically expires at the end of the compliance period. The manufacturer may 

request a renewal of the Program by submitting a renewal request that shall include an updated 

Program, meeting all applicable Program requirements. The renewal request will be considered 

conditionally approved until the Executive Officer makes a final decision to deny or approve the 

renewal request based on a determination of whether the manufacturer is likely to comply with the 

averaging requirements. The Executive Officer shall base such determination on all available 

information, including but not limited to, the mid-term and the final reports of the preceding 

compliance period. The Executive Officer shall make a decision to deny or approve a renewal 
[Draft of May 15, 2014]

Santa Barbara County APCD Rule 323 323 -20 November 15, 2001

request no later than 45 days from the date of the final report submittal, unless the manufacturer 

and the Executive Officer agree to an extension of time for the Executive Officer to take action on 

the renewal request.

A.6 MODIFICATION OF A PROGRAM

A Manufacturer may request a modification of the Program at any time prior to the end of the 

compliance period. The Executive Officer shall take action to approve or disapprove the 

modification request no longer than 45 days from the date of its submittal. No modification of the 

compliance period shall be allowed. A Program need not be modified to specify additional 

coatings to be averaged that are below the applicable VOC limits.

A.7 TERMINATION OF A PROGRAM

A.7.1 A manufacturer may terminate its Program at any time by filing a written notification to 

the Executive Officer. The filing date shall be considered the effective date of the 

termination, and all other provisions of this rule including the VOC limits shall 

immediately thereafter apply. The manufacturer shall also submit a final report 60 days 

after the termination date. Any exceedance of the actual emissions over the allowable 

emissions over the period that the Program was in effect shall constitute a separate 

violation for each day of the entire compliance period.

A.7.2 The Executive Officer may terminate a Program if any of the following circumstances 

occur:

A.7.2.1 The manufacturer violates the requirements of the approved Program, and at 

the end of the compliance period, the actual emissions exceed the allowable 

emissions.

A.7.2.2 The manufacturer demonstrates a recurring pattern of violations and has 

consistently failed to take the necessary steps to correct those violations.

A.8 CHANGE IN VOC LIMITS

If the VOC limits of a coating listed in the Program are amended such that its effective date is less 

than one year from the date of adoption, the affected manufacturer may base its averaging on the 

prior limits of that coating until the end of the compliance period immediately following the date 

of adoption.

A.9 LABELING

Each container of any coating that is included in Averaging Program, and that exceeds the 

applicable VOC limit in Table 1 shall display the following statement: “This product is subject to 

architectural coatings averaging provision in California.” A symbol specified by the Executive 

Officer may be used as a substitute.

A.10 VIOLATIONS

The exceedance of the allowable emissions for any compliance period shall constitute a separate 

violation of each day of the compliance period. However, any violation of the requirements of the 

Averaging Provision of this rule, which the violator can demonstrate, to the Executive Officer, did 

not cause or allow the emission of an air contaminant and was not the result of negligent or 

knowing activity may be considered a minor violation.

ATTACHMENT D - SUMMARY OF REASONS FOR SIGNIFICANT DIFFERENCES BETWEEN THE 2007 ARB SCM AND RULE 323.1

Page 1, May 15, 2014

2007 ARB SCM (Rule 323.1

Section)

Deleted 2007 ARB SCM Text (Shown with Strikethroughs) and 

Added Text (Shown with Underlines)

Reason for a Deviation from the 2007 ARB SCM 

Provision

1. APPLICABILITY

(A. Applicability)

2. Rule 323.1 shall be effective on January 1, 2015. The 2007 Air Resources Board Suggested Control 

Measure for Architectural Coatings (2007 ARB SCM) 

does not include a rule effective date.

Staff added the January 1, 2015 effective date at the 

request of a stakeholder. If the District adopts Rule 

323.1 before July, manufacturers assured us that they 

will have enough lead-time for complying with the new 

requirements. 

1. APPLICABILITY

(A. Applicability)

3. Rule 323, Architectural Coatings, shall remain in effect in its 

entirety until January 1, 2015. A coating manufactured prior to 

January 1, 2015 may be sold, supplied, or offered for sale for up 

to three years after January 1, 2015, provided that the coating 

complied, at the time of manufacture, with all applicable 

provisions in Rule 323 as revised November 15, 2001. Such 

coating may also be applied at any time, both before and after 

January 1, 2015. This Section does not apply to any coating that 

does not display the date or date code required by Section E.1.a 

of this rule.

The District copied the D.3 sell-through of coatings

provision into A.1 at the request of stakeholder.

For ease of reference, we will maintain an archived 

version of Rule 323 on our web site after it has been 

superseded.

2. SEVERABILITY 2.1 Each provision of this rule shall be deemed severable, and in the

event that any provision of this rule is held to be invalid, the

remainder of this rule shall continue in full force and effect.

A “Severability” provision in Rule 323.1 is not 

necessary because the rulebook includes Rule 103, 

“Severability,” which indicates: 

If any Rule or any portion of a Rule is, for any reason, 

held to be invalid or unconstitutional, such finding shall 

have no effect on the enforceability of the remaining 

Rules and/or portions of Rules, which shall continue to 

be in full force and effect.

3. EXEMPTIONS

(B. Exemptions)

3.2. With the exception of section 7Section F, this rule doesshall not 

apply to any architectural coating that is sold in a container with 

a volume of one liter (1.057 quartquarts) or less. provided:

a. The coating containers are not bundled together to be sold 

as a unit that exceeds one liter (1.057 quarts), excluding 

containers packed together for shipping to a retail outlet, 

warehouse, or a military distribution or redistribution 

facility.

The ARB suggested that the District model this revised 

one liter exemption on the SCAQMD Rule 1113, §(f)(1) 

bundling provisions. Based on stakeholder feedback, 

staff deleted Section B.2.b text from the March 7 draft, 

which had prohibited suggesting the combination of 

multiple containers on labels and product data.

Reason for a Deviation from the 2007 ARB SCM 

Provision

3. EXEMPTIONS

(B. Exemptions)

3. Any architectural coating operation that is not conducted as part 

of a business is exempt from the requirements of Section D.4 of 

this rule.

This was added to make the applicability of painting 

practices consistent with those found in other District 

rules.

3. EXEMPTIONS

(B. Exemptions)

4. Early Rule 323.1 compliance provision: 

Prior to January 1, 2015, any coating that meets the definition in 

Section C for a coating category listed in Table 323.1-1 and 

complies with the corresponding VOC limit in Table 323.1-1 

and with the Most Restrictive VOC limit in Section D.2 and the 

corresponding Labeling Requirement in Section E, if applicable, 

shall be considered in compliance with this rule and exempt 

from Rule 323.

At least three coatings have higher VOC content limits 

in Rule 323.1: Reactive Penetrating Sealers, Stone 

Consolidants, and Tub and Tile Refinish Coatings. By 

adding an early compliance provision, manufacturers 

will gain the advantage of being able to immediately 

market higher VOC content products consistent with the 

2007 ARB SCM.

3. EXEMPTIONS

(B. Exemptions)

5. With the exception of Sections E and F, this rule shall not apply 

to any coating that contains less than 20 grams of VOC per liter 

(0.17 pounds of VOC per gallon) of coating, less water and less 

exempt compounds, as applied.

Added at the request of stakeholders. Coating Rules 330 

and 337 have a similar exemption.

4. DEFINITIONS

(C. Definitions)

“Ablative Coating” means any coating that chars when exposed 

to open flame or extreme temperatures, as would occur during a 

rocket launch. The ablative char surface serves as an insulative 

barrier, protecting underlying coatings or surfaces from the heat 

or open flame.

A stakeholder requested we add this definition, the term 

to Table 323.1-1 as a specialty coating, and a 250 

grams/liter VOC Content limit for it. The Industrial 

Maintenance Coating category has a similar limit. 

Hence, the District agreed to this request.

4. DEFINITIONS

(C. Definitions)

4.17 Exempt Compound: A “Exempt Compound” means any 

compound identified as exempt under the definition of “Volatile 

Organic Compound (VOC), subsection 4.63.” Tertiary-butyl 

acetate, also known as t-butyl acetate or tBAc, shall be considered 

exempt as a VOC only for purposes of VOC emissions limitations 

or VOC Content requirements and shall be considered a VOC for 

purposes of all recordkeeping, emissions reporting, photochemical 

dispersion modeling, and inventory requirements which apply to 

VOCs. Exempt compounds content of a coating shall be 

determined by U.S. EPA Environmental Protection Agency 

Method 24 or South Coast Air Quality Management District 

(SCAQMD) Method 303-91 (Revised 19936), “Determination of 

Exempt Compounds,” [. . .]

The District drafted this text to be similar to the Rule 

102 definition of “Exempt Compound” (sans the text on 

how exempt compounds content is determined). The 

text on tBAc is needed to address requirements in 40 

CFR 51.100(s)(5) and EPA concerns.

Provision

4. DEFINITIONS

(C. Definitions)

4.20 Fire-Retardant Coating: A coating labeled and formulated to 

retard ignition and flame spread, that has been fire tested and 

rated by a testing agency approved by building code officials for 

use in bringing building and construction materials into 

compliance with federal, state and local building code 

requirements. The fire-retardant coating and the testing agency 

must be approved by building code officials. The fire-retardant 

coating shall be tested in accordance with ASTM Designation E 

84-07, incorporated by reference in subsection 8.5.1.

Effective January 1, 2010, the Fire Retardant coating 

category is eliminated and coatings with fire retardant 

properties will be subject to the VOC limit of their primary 

category (e.g., Flat, Nonflat, etc.).

The SCM indicates the category is eliminated effective 

01/01/2012. Since we are well past this deadline, staff 

decided to eliminate the term now.

4. DEFINITIONS

(C. Definitions)

4.24 Gonioapparent: A change in appearance with a change in the 

angle of illumination or the angle of view, as defined according to 

ASTM E-284-06b, incorporated by reference in subsection 8.5.13.

Should delete per ARB (old term no longer necessary).

4. DEFINITIONS

(C. Definitions)

“Manufacturer” means any person, company, firm, or 

establishment who imports, blends, assembles, produces, 

packages, repackages, or re-labels any architectural coating, not 

including retail outlets where labels or stickers may be affixed to 

architectural coating containers or where colorant is added at the 

point of sale.

This definition (modeled on the SC Rule 1113 

definition) is needed to avoid creating a loop hole on the 

labeling requirements in Section F for blenders and 

repackagers.

4. DEFINITIONS

(C. Definitions)

4.33 Metallic: Similar to the appearance of a gonioapparent 

material, as defined herein, containing metal flakes.

Should delete per ARB (old term, no longer needed).

4. DEFINITIONS

(C. Definitions)

“Multicomponent Coating” means any coating requiring the 

addition of a separate reactive resin, commonly known as a 

catalyst or hardener, before application to form an acceptable dry 

film

Staff added a definition of multicomponent coating for 

clarity. We used the SC 1113 definition as a model.

(C. Definitions)

4.54 Specialty Primer, Sealer, and Undercoater: A coating that is 

formulated for application to a substrate to block water-soluble 

stains resulting from: fire damage; smoke damage; or water 

damage.

Specialty Primers, Sealers, and Undercoaters must be labeled 

in accordance with subsection 6.1.7.

For all intents and purposes, the SCM could have 

indicated that this category was being deleted effective 

01/01/2012. According to the SCM, on 01/01/2012:

1. The Table 1 VOC limit for “Specialty Primers, 

Sealers, and Undercoaters” becomes 100 g/l; which is 

the same limit as “Primers, Sealers, and Undercoaters;” 

and

2. The labeling requirements in §6.1.7 for “Specialty 

Primers, Sealers, and Undercoaters” end on 01/01/2012.

Since we are well past the 01/01/2012 deadline, staff 

have chosen to delete the category now. Once Rule 

323.1 becomes effective, a three year sell through 

period will begin for these products. The SCM 

“Specialty Primer, Sealer, and Undercoater” provision 

on blocking stains caused by fire, smoke, or water 

damage will be covered by the item “f” of the “Primer, 

Sealer, and Undercoater” provision: To block materials 

from penetrating into or leaching out of a substrate.

4. DEFINITIONS

(C. Definitions)

4.63 Volatile Organic Compound (VOC): Any volatile “Volatile 

Organic Compound (VOC)” means any compound containing [. 

. .]

The revised definition is essentially the same as the 

Rule 102 definition of “Reactive Organic Compound.” 

The definition includes text on tBAc to address 

requirements in 40 CFR 51.100(s)(5) and EPA 

concerns.

5. STANDARDS

to tint bases.

Staff deleted the text on thinning and excluding colorant 

because it is redundant to Table 323.1-1 lead-in text.

5.33. Sell-Through of Coatings: 

A coating manufactured prior to the effective date specified for

that coating in Table 1January 1, 2015 may be sold, supplied, or

provided that the coating complied, at the specified effective date.

In addition, atime of manufacture, with all applicable provisions 

in Rule 323 as revised November 15, 2001. Such coating 

manufactured before the effective date specified for that coating 

in Table 1 maymay also be applied at any time, both before and 

after the specified effective date, so long as the coating complied

with the standards in effect at the time the coating was

manufactured.January 1, 2015. This subsection 5.3 Section does 

not apply to any coating that does not display the date or datecode required by subsection 6.1.1Section E.1.a of this rule.

The deviation from the SCM is needed because the 

District is transitioning from the existing Rule 323 

limits through the new and separate Rule 323.1. We 

propose that Rule 323.1 will become effective January 

1, 2015. The three year sell through provision will 

commence from the rule’s effective date.
