### STAFF REPORT

Rule 1168 – Adhesive and Sealant Applications

I. PURPOSE OF STAFF REPORT
A staff report serves several discrete purposes. I ts primary purpose is to provide a summary and background material to the members of the Governing Board. This allows the members of the Governing Board to be fully informed before making any required decision. It also provides the documentation necessary for the Governing Board to make any findings, which are required by law to be made prior to the approval or adoption of a docu ment. In addition, a staff report ensures that the correct procedures and proper documentation for app roval or adoption of a document have been performed. Finally, the staff report provides evid ence for defense against legal challenges regarding the propriety of the approval or adoption of the do cument.

II. EXECUTIVE SUMMARY
On July 1, 1997 the Antelope Valley Air Pollution C ontrol District (AVAPCD) was created pursuant to statute (former H&S Code §40106, A.B. 266-Knight Ch . 542, statutes of 1996) and assumed all air pollution control responsibilities from the South C oast Air Quality Management District (SCAQMD) for the area of Los Angeles County outside the Sout h Coast Air Basin (SCAB). The SCAQMD rules in effect within the jurisdiction of the AVAPCD rem ained in effect until the AVAPCD Governing Board superseded, amended, or rescinded them. On J anuary 1, 2002 the Antelope Valley Air Quality Management District (AVAQMD) was created pursuant t o statute (California Health & Safety (H&S) Code §41300 et seq.) to replace the AVAPCD. Once a gain the rules in effect at the time of the change remained in effect until the AVAQMD Governing Board superseded, amended or rescinded them. Rule 1168 was most recently amended by the AVAQMD o n January 19, 2010.

The Federal Clean Air Act (FCAA; 42 U.S.C. §§7401 e t seq.) requires areas designated nonattainment for ozone and classified moderate and above to adop t and maintain Reasonably Available Control Technology (RACT) rules for source categories emitt ing Volatile Organic Compounds (VOC) and Oxides of Nitrogen (NO x ) for which the United States Environmental Protect ion Agency (USEPA) has issued a Control Techniques Guideline (CTG) documen t. In addition, such areas are required to adopt and maintain RACT rules for all other major station ary sources of VOCs and NO x (42 U.S.C. §7511a(b)(2); FCAA §182(b)(2)). The Antelope Valle y has been designated non-attainment for the 8 hr ozone standard and classified moderate.

The January 19, 2010 amendment of Rule 1168 was pri marily designed to update and refine adhesive categories, create new sealant and sealant primer c ategories and modify exemptions and definitions to harmonize with the CTG and the latest State Impleme ntation Plan (SIP) approved SCAQMD rule. The amendment also removed dated provisions that had ex pired by their terms. However, since that time, the District received comments from both the Califo rnia Air Resources Board (CARB) and USEPA that are being addressed in this rule amendment. T his rule amendment will modify and add definitions, align the source categories to those in the CTG, de crease the VOC limits for several source categories

, increase the emission control efficiency requiremen ts, correct several typographical errors, and modif y the provisions of the sales and use section to be i nclusive of any listed chemicals. USEPA indicated2 AVAQMD Rule 1168 Final Staff Report, 12/08/11 that the emission control efficiency deficiency was significant enough to propose a partial approval/ partial disapproval. Therefore, the AVAQMD is prop osing to amend Rule 1168 to address CARB and USEPA comments and make the rule SIP approvable.

III. STAFF RECOMMENDATION
Staff recommends that the Governing Board of the AV AQMD adopt the proposed amendments to Rule 1168 – Adhesive and Sealant Operations and approve the appropriate California Environment al Quality Act Documentation. This action is necessar y to address CARB and USEPA comments and make Rule 1168 approvable into the SIP.

A. REQUIRED ELEMENTS/FINDINGS

This section discusses the State of California stat utory requirements that apply to the proposed amendment of Rule 1168. These are actions, that ne ed to be performed, and/or information, that must be provided in order to amend the rule in a procedurally correct manner.

1. State Findings Required for Adoption of Rules & Regulations:

Before adopting, amending, or repealing a rule or r egulation, the AVAQMD Governing Board is required to make findings of necessity, au thority, clarity, consistency, nonduplication, and reference based upon relevant info rmation presented at the hearing. The information below is provided to assist the AVA QMD Governing Board in making these findings.

a. Necessity:

The amendment of Rule 1168 is necessary to address substantive CARB and USEPA comments pertaining to the January 19, 2010 a mendment.

b. Authority:

AVAQMD has the authority pursuant to H&S Code §4070 2 to adopt, amend or repeal rules and regulations.

c. Clarity:

The amendments are clear in that they are written s o that the persons subject to the rule can easily understand the meaning.

d. Consistency:

The amendment of Rule 1168 is in harmony with, and not in conflict with or contradictory to, any state law or regulation, fede ral law or regulation, or court decisions because they align source categories and emission control efficiency requirements to those contained in the CTG.

e. Non-duplication:

The amendment of Rule 1168 does not impose the same requirements as an existing state or federal law or regulation because the CTG is primarily a guidance document and requires rule adoption to imp lement its provisions and this amendment will align source categories and emi ssion control efficiency requirements to those contained in the CTG.AVAQMD Rule 1168 5

Final Staff Report, 12/08/11

f. Reference:

AVAQMD has the authority pursuant to H&S Code §4070 2 to adopt, amend or repeal rules and regulations.

g. Public Notice & Comment, Public Hearing:

Notice for the public hearing for the proposed amen dment of Rule 1168 was published August 18, 2011. See Appendix “B” for a copy of the public notice. See Appendix C for copies of comments, if any, and AVAQMD responses.

2. Federal Elements (SIP Submittals, Other Federal Submittals).

Submittals to USEPA are required to include various elements depending upon the type of document submitted and the underlying federal la w which requires the submittal. The information below indicates which elements are required for the proposed amendment of Rule 1168 and how they were satisfied.

a. Satisfaction of Underlying Federal Requirements:

The FCAA requires areas designated nonattainment fo r ozone and classified moderate and above to adopt and maintain RACT rules for source categories emitting VOCs and NO x for which USEPA has issued a CTG document. In addition, such areas are required to adopt and main tain RACT rules for all other major stationary sources of VOCs and NO x (42 U.S.C. §7511a(b)(2); FCAA §182(b)(2)). Such RACT rules are required to be su bmitted into the SIP for the affected area.

USEPA has indicated that the January 19, 2010 amend ment contained deficiencies which were significant enough to propo se a partial approval/ partial disapproval. The amendment corrects these deficien cies and will be submitted for inclusion into SIP. The criteria for determini ng completeness of SIP submissions are set forth in 40 CFR Part 51 Appendi x V, 2.0. This staff report and supporting adoption documentation will satisfy the completeness requirements. See subsection (VI)(E) for the SIP h istory of this rule.

b. Public Notice and Comment:

Notice for the public hearing for the proposed amen dment of Rule 1168 was published August 18, 2011. See Appendix “B” for a copy of the public notice.

c. Availability of Document:

Copies of proposed amended Rule 1168 and the accomp anying draft staff report were made available to the public on August 8, 2011

.6 AVAQMD Rule 1168 Final Staff Report, 12/08/11 d. Notice to Specified Entities

Copies of proposed amended Rule 1168 and the accomp anying draft staff report were mailed to all affected agencies, including but not limited to CARB and USEPA on August 8, 2011.
e. Public Hearing:

A public hearing to consider the proposed amendment of Rule 1168 was held on September 20, 2011.

f. Legal Authority to Adopt and Implement:

The AVAQMD has the authority pursuant to H&S Code § 40702 to adopt, amend, or repeal rules and regulations and to do su ch acts as may be necessary or proper to execute the duties imposed upon the AV AQMD.
g. Applicable State Laws and Regulations Were Follo wed:

Public notice and hearing procedures pursuant to H& S Code §§40725-40728 have been followed. See Section (V)(A)(1) above fo r compliance with state findings required pursuant to H&S Code §40727. See Section (V)(B) below for compliance with the required analysis of existing r equirements pursuant to H&S Code §40727.2. See Section (V)(C) for compliance w ith economic analysis requirements pursuant to H&S Code §40920.6. See Se ction (V)(D) below for compliance with provisions of the California Enviro nmental Quality Act (CEQA).

B. WRITTEN ANALYSIS OF EXISTING REQUIREMENTS
H&S Code §40727.2 requires air districts to prepare a written analysis of all existing federal air pollution control requirements that apply to the sa me equipment or source type as the rule proposed for modification by the District. The ame ndments to Rule 1168 align source categories and emission control efficiency requirem ents to those contained in the CTG. The CTG is primarily a guidance document and requires r ule adoption to implement its provisions. Therefore, the preparation of a written analysis of existing pollution control requirements that apply to the same equipment or source type is not r equired.

C. ECONOMIC ANALYSIS

1. General

The amendment of Rule 1168 will align source catego ries and emission control efficiency requirements to those contained in the C TG, and which is the current state of adhesive and technology for miscellaneous industria l sources. The economic impact of the proposed amendments is expected to be minimal.AVAQMD Rule 1168 7

Final Staff Report, 12/08/11

2. Incremental Cost Effectiveness

Pursuant to H&S Code §40920.6, incremental cost eff ectiveness calculations are required for rules and regulations which are adopte d or amended to meet the California Clean Air Act requirements for Best Available Retro fit Control Technology (BARCT) or “all feasible measures” to control volatile comp ounds, oxides of nitrogen or oxides of sulfur.

The amendments to Rule 1168 are not subject to incr emental cost effectiveness calculations because this rule does not impose BARC T or “all feasible measures.”

D. ENVIRONMENTAL ANALYSIS (CEQA)
Through the process described below, it was determi ned that a Notice of Exemption would be the appropriate CEQA process for the proposed amend ment of Rule 1168.

1. The amendment of Rule 1168 meets the CEQA defini tion of “project.” They are not “ministerial” actions.

2. The amendment of Rule 1168 is exempt from CEQA r eview because it will not create any adverse impacts on the environment. The proposed requirements in the proposed amendments to Rule 1168 are more stringent than the currently existing requirements (see more detailed discussion in Rule Summary Section (D)) in that: rule applicability is expanded to include current CTG so urce categories; definitions are updated to make the rule more comprehensive, and VO C limits for several categories of adhesives and solvents have been adjusted downward to align with current limits in neighboring districts. Other air districts have ad opted similar rules and neither they nor USEPA has identified increased usage of adhesives o r sealants as a result of the new limits.

Therefore, no adverse environmental effects are for eseen from the amendment and there is not potential that the amendments might cause th e release of additional air contaminants or create any adverse environmental im pacts. Therefore, a Class 8 categorical exemption (14 Cal. Code Reg. §15308) ap plies. Copies of the documents relating to CEQA can be found in Appendix “D”.

E. SUPPLEMENTAL ENVIRONMENTAL ANALYSIS
1. Potential Environmental Impacts

No significant impacts have been identified as a re sult of the proposed amendments. This is primarily due to the fact that the proposed amendments to VOC limits primarily reflect the currently available state of technology within the source category. Products meeting the proposed VOC limits are readily availab le in commerce and are currently in use within the District. Amounts of product used a nd methods of use are not expected to change as a result of the proposed amendments. In addition, the amendments will8 AVAQMD Rule 1168 Final Staff Report, 12/08/11 result in better enforcement by the District agains t the use of non-compliant adhesives, sealants and sealant primers due to the conformance of the categories with those included in the CTG and currently used in commerce.

VI. TECHNICAL DISCUSSION

A. SOURCE DESCRIPTION

Rule 1168 - Adhesive and Sealant Applications applies to all industrial and commercial sales and applications of adhesives, sealants and sealant primers. Specifically, Rule 1168 applies to adhesives, sealants and their associated primers ap plication to general metals, plastics and plastic foams, glass, ceramics, rubber, wood, drywa ll, concrete, masonry and non-graphic arts paper products. Excluded from this rule are adhesi ves and sealants that are covered by other source specific rules such as Rule 1124 , 1104, 1130 and 1128. The list of these exclusions includes adhesives used in aerospace, flat wood ope rations, flat stock graphic arts (lithographic, flexographic, gravure, letterpress and screen-print ing), paper, fabric and film, and aerosol adhesives.

Because a disproportionate amount of adhesives and sealants are applied by trowel, cartridges, syringes or are sprayed in low volumes (less than o ne gallon per day), most emissions are exempt from any permitting and reporting requiremen ts and are accountable as non-permitted or area source emissions. It should be noted that SCAQMD had reported in their year 2000 Rule 1168 amendment staff report that the SCAQMD’s Annual Emission Reporting program, which applies to the largest facilities in the Dist rict, accounts for less than 10 percent of the annual average VOC inventory of 7.8 tons per day, a s reported in the 1997 AQMP for the adhesives universe of sources. Because of the diff erence in population and affected sources the AVAQMD would expect a lesser proportion as the Dist rict has not recognized any major facility for miscellaneous adhesive and sealant app lications.

B. EMISSIONS
In response to VOC limits for adhesives and sealant s set forth in the CTG and in SCAQMD technology driving Rule 1168, manufacturers have pr oduced products that in most cases meet or exceed the current requirements. Listed below i n Table 1 is a side by side comparison of current Rule 1168, the CTG, SCAQMD Rule 1168 and th e proposed AVAQMD amended emission limits. This table indicates which catego ries have been adjusted and which are newAVAQMD Rule 1168 9

C. CONTROL REQUIREMENTS
A person may comply with the VOC content of adhesiv es, adhesive Primers, sealants and sealant primers pursuant to subsection (C)(1) of th e rule, the transfer efficiency as pursuant to subsection (C)(5) of the rule, by using approved ai r pollution control equipment provided that the VOC emissions from such operations and/or mater ials are reduced by 85 percent overall by weight pursuant to subsection (C)(6) of the rule, o r submission of an Alternate Emission Control Plan pursuant to District Rule 108.

D. PROPOSED RULE SUMMARY
This section gives a brief overview of the proposed amendments to Rule 1168.

Section (A) was amended to reflect the proposed VOC categories.

Section (B) has had the following definitions remov ed as they are not used in the rule: Adhesive Promoter; Nonmembrane Roof Adhesive; Polyc arbonate; Polyethylene Terephalate Glycol (PETG); Polyurethane Foams; Propellant; and, Rubber Foam. The following new definitions have been added to Section (B): Archit ectural; Flexible Vinyl; Floor Covering Installation Adhesive (Indoor); Floor Covering Inst allation Adhesive (Outdoor); Marine Deck Sealant; Metal to Urethane/Rubber Molding or Castin g Adhesive; Motor Vehicle Adhesive; Motor Vehicle Glass Bonding Primer; Motor Vehicle W eatherstrip Adhesive; Plastic Foam; Plastic Solvent Welding Adhesive (ABS); Plastic Sol vent Welding Adhesive Primer; Plastic Solvent Welding Adhesive (CPVC); Plastic Solvent We lding Adhesive (PVC); Reinforced Plastic Composite; Rubber; Single-Ply Roof Membrane Adhesive Primer; Vinyl CompositionAVAQMD Rule 1168 13

Final Staff Report, 12/08/11 Tile (VCT) and Asphalt Tile Adhesive; and, Waterpro of Resorcinol Glue. The definition for HVLP has been updated to address CARB comment. Def initions have been alphabetized as needed, and several typographical errors have also been corrected.

Subsection (B)(28) and (B)(100) have been modified to reflect the federal definition of VOC and to be consistent with the District TBAC policy.

Subsection (C)(2) has been modified to align the so urce categories of the CTG for Miscellaneous Industrial Adhesives, September 2008. The source category for PVC Welding in the CTG is 500 g/L. USEPA will accept the current rule limit of 510 g/L. The limit for the Top and Trim category will be lowered to 250 g/L for co nsistency with the current SCAQMD rule. The limit for Sealant (Other) will be lowered to 42 0 g/L for consistency with the current SCAQMD rule. Other source categories have been ren amed for consistency with existing categories and definitions and for ease of use.

Subsection (C)(5)(g) has been modified to require o ther application methods as efficient as HVLP.

Subsection (C)(6) has been revised to meet the CTG control efficiency requirement.

Subsection (H)(2) has been amended so that the proh ibition of sales and use applies to products containing any of the listed chemicals in the subse ction.

Subsection (J)(8) has been modified to require spec ific products dispensed from aerosol spray cans to comply with CARB consumer product regulatio n found in Title 17 of the California Code of Regulations beginning at §94507.

Various changes have been made for consistency with in the rule that do not affect rule content.

E. SIP HISTORY
1. SIP History.

Prior to 1975 the original air district for the Ant elope Valley region was the Los Angeles County Air Pollution Control District that had a ju risdiction covering the entire county of Los Angeles. In 1975, the Southern California A PCD was created. It was a joint powers authority that had a jurisdiction covering a ll of the counties of Los Angeles, Orange, Riverside and San Bernardino. The SCAQMD c ame into existence pursuant to statute on February 1, 1976 and originally covered only the areas within the South Coast Air Basin (SCAB). The legislation was thereafter a mended to allow non SCAB areas to “opt in.” Los Angeles County exercised this option and thus the Antelope Valley became a part of SCAQMD. On July 1, 1997 the AVAPC D replaced the SCAQMD as the agency with jurisdiction over the Los Angeles C ounty portion of the Mojave Desert Air Basin (MDAB). On January 1, 2002 the AVAPCD wa s replaced by the AVAQMD. Pursuant to both statutory changes, the rule and r egulations of the predecessor district were retained until the Governing Board adopted, am ended or rescinded them. At the14 AVAQMD Rule 1168 Final Staff Report, 12/08/11 first meeting of both the AVAPCD and the AVAQMD, th e respective Governing Boards reaffirmed all the rules and regulations in effect at the time the agency changed.

The jurisdiction of the AVAPCD and the AVAQMD were specified in the statutes as the portion of the Los Angeles County contained wit hin the MDAB. The MDAB was formerly known as the Southeast Desert Air Basin (S EDAB). In 1997 the SEDAB was split into the MDAB and the Salton Sea Air Basin. Descriptions of these air basins can be found in 17 Cal. Code Regs. §§60109 and 60144. Since USEPA adopts SIP revisions in California as effective within jurisdi ctional boundaries of local air districts, when the local air district boundaries change the S IP as approved by USEPA for that area up to the date of the change remains as the SI P in that particular area. Thus, upon creation of the AVAPCD on July 1, 1997 the AVAPCD a cquired the SIP applicable to the Antelope Valley portion of the SCAQMD that was effective as of June 30, 1997. Likewise the AVAQMD acquired the SIP that was effec tive in the jurisdiction of the AVAPCD as of December 31, 2000. Therefore, the SIP history for this region is based upon the rules adopted, effective, and approved for the Antelope Valley by SCAQMD.

Rule 1168 was originally adopted by SCAQMD on April 7, 1989. It was thereafter amended by SCAQMD on February 1, 1991, July 19, 199 1, August 2, 1991, December 10, 1993, and April 11, 1997. The April 11, 1997 i s the version of the rule retained by the AVAPCD upon its creation and also retained by t he AVAQMD upon its creation. The AVAQMD could find no evidence that this version of the rule was acted upon by USEPA as a SIP submission. There is no SIP rule in shown in effect for this source category currently in the SIP within the jurisdicti on of the AVAQMD.

2. SIP Analysis.

The proposed amendments of Rule 1168 are derived fr om SCAQMD Rule 1168 as amended October 3, 2003 and January 7, 2005, and th e CTG for Miscellaneous Industrial Adhesives (September 2008). The SCAQMD version of 1168 as amended October 3, 2003 was approved into the SIP for SCAQM D on December 12, 2003 at 68 FR 69320. The proposed amendments to Rule 1168 are primarily designed to address substantive CARB and USEPA comments. This rule ame ndment will modify and add definitions, align the source categories to those i n the CTG, decrease the VOC limits for several source categories, increase the emission co ntrol efficiency requirements, correct several typographical errors, and modify the provis ions of sales and use section to be inclusive of any listed chemicals. USEPA indicated that the emission control efficiency deficiency was significant enough to propose a part ial approval/ partial disapproval. Therefore, the AVAQMD is proposing to amend Rule 11 68 to address CARB and USEPA comments and make the rule SIP approvable.AVAQMD Rule 1168 A
