### SIP COMPLETENESS CHECKLIST (Electronic Format)

*** TO BE COMPLETED BY DI STRICT AND RETURNED TO ARB ***

All rules submitted to the EPA as State Implementation Plan (SIP) revisions must be suppor ted by certain information and documentation for the rule packages to be deemed complete for review by the EPA. Rules will not be evaluated for approvability by the EPA unless the submittal packages are comple te. To assist you in determining that all necessary materials are included in rules packages sent to the ARB fo r submittal to the EPA, please fill out the following form and include it with the rule package you send ARB. See the ARB's Guidelines on the Impl ementation of the 40 CFR 51, Appendix V , for a more detailed explanation than is provi ded here. Adopted rules and rule amendments should be checked against U.S. EPA's Guidance Document for Correcting Common VOC & Other Rule Deficiencies (Little Blue Book, August 21, 2001) to ensure that they contain no elements which will result in disapproval by EPA.

District: Sacramento Metropolit an Air Quality Management District

Rule No: 456

Rule Title: Aerospace Assembly and Component Coating Operations

Date Adopted or Amended: Amended on July 23, 1998 and October 23, 2008

ADMINISTRATIVE MATERIALS

Note: All documents should be in electronic format. Items that have signatures, initials, or stamps may be scanned.

Not Attached Attached N/A

COMPLETE COPY OF THE RULE: Provide an unmarked copy of the entire rule as adopted or amended by your District Board.

UNDERLINE AND STRIKEOUT COPY OF THE RULE : If an amended rule,

provide a complete copy of the ru le indicating in underline and strikeout format all language which has been added, deleted, or changed since the rule was last adopted or amended.

COMPLETE COPY OF THE REFERENCED RULE(S): For any rule which

includes language specifically referencing another rule, a copy of that other rule must also be submitted, unless it has already been submitted to EPA as part of a previous SIP submittal.

PUBLIC NOTICE EVIDENCE: Include a copy of the local newspaper clipping

certification(s), stating t he date of publication, whic h must be at least 30 days before the hearing. As an alternative, include a copy of the actual published notice of the public hearing as it appeared in the local newspaper(s). In this case, however, enough of the newspaper page must be included to show the date of publication. The notice must s pecifically identify by title and number each rule adopted or amended.

RESOLUTION/MINUTE ORDER: Provide the Board Clerk certified resolution

or minute order. This document must include certification that the hearing was held in accordance with the informati on in the public notice. It must also list the rules that were adopted or am ended, the date of the public hearing, and a statement of compliance with California Health and Safety Code Sections 40725-40728 (Administr ative Procedures Act).

PUBLIC COMMENTS AND RESPONSES: Submit copies of written public

comments made during the notice period and at the public hearing. Also submit any written responses prepared by the District staff or presented to the District Board at the public hearing.

TECHNICAL MATERIALS

Not Attached Attached N/A

RULE EVALUATION FORM: See instructions for completing the Rule Evaluation Form and the accompanying sample form.

NON-EPA TEST METHODS: Attach all test methods that are referenced in

your rule that do not appear in 40 CFR 51, 60, 61, 63, or have not been previously submitted to EPA. EPA me thods used in other media such as SW846 for solid waste are not autom atically approved for air pollution applications. Submittal of test me thods that are not EPA-approved should include the information and follow the procedure described in Region 9’s “Test Method Review & Evaluation Process.”

MODELING SUPPORT: Provide if appropriate. In general, modeling support

is not required for VOC and NOx rules to determine their impacts on ozone levels. Modeling is required where a ru le is a relaxation that affects large sources (> 100 TPY) in an attainment area for SO2, directly emitted PM10, CO, or NOx (for NO2 purposes). In cases where EPA is concerned with the impact on air quality of rule revisions which relax limits or cause a shift in emission patterns in a nonattainment area, a reference back to the approved SIP will be sufficient provided the appr oved SIP accounts for the relaxation and provided the approved SIP used the current EPA modeling guidelines. If current EPA modeling guidelines were not used, then new modeling may be required.

ECONOMIC AND TECHNICAL JUSTIFICATION FOR DEVIATIONS FROM

EPA POLICIES : The District staff report or other information included with the submittal should discuss all potential relaxations or deviations from RACT, RACM, BACT, BACM, enforceability, atta inment, RFP, or other relevant EPA requirements. This includes, for exampl e, demonstrating that exemptions or emission limits less stringent than the presumptive RACT (e.g., a CTG) meet EPA’s 5 percent policy, and demonstrating that all source categories exempted from a RACM/BACM rule are de minimus according to EPA’s RACM/BACM policy.

ADDITIONAL MATERIALS : Provide District staff reports and any other

supporting information concerning developm ent of the rule or rule changes. This information should explain the basis for all limits and thresholds contained in the rule.CALIFORNIA AIR RESOURCES BOARD

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

The amendments lowered the solvent VOC limits for cleani ng of spray guns used in coating operations from 200 g/l to 25 g/l. The amendments also added a sunset date fo r the option of using an enclosed gun cleaner in lieu of complying with the VOC limit for the cleaning of spra y guns used in any coating operations except for the application equipment used in the rocket motor lining proce ss. Application equipment used in the rocket motor lining process are allowed to be cleaned in an enclosed gun cl eaner or with a solvent that complies with the 25 g/l VOC limit. The amendments also revised the low usage exem ption to allow the use of up to 200 gallons per year

of rocket motor adhesive that does not m eet the VOC limits specified in this rule, provided that the VOC content of the rocket motor adhesives does not exceed 890 g/l. Th is exemption also limits the usage of all materials, excluding rocket motor adhesives, that do not meet the VOC lim its specified in this rule to a total 55 gallons per year and limit the usage of all materials, including ro cket motor adhesives, that do not meet the VOC limits sepcified in this rule to a total of 200 gallons per year.

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 showi ng how the emission information provided below was determined

.

Net Effect on Emissions: Increase Decrease N/A

Emission Reduction Commitment in SIP for this Source Ca tegory: The 1994 SIP included a commitment to reduce VOC emissions from surface preparation and cleanup solvents by 2.9 tpd from the Sacramento district. Surface preparation and cleanup solvents are included in multiple rules. Prior to amendment of this rule, the district had reduced emissions from this category by 2.5 tpd. This rule amendment reduc es emissions from this category by 0.01 tons per year (0.00002 tpd). Together with the 2008 am endments to eight other prohibitory rules with surface preparation and cleanup requirements, the total emission reducti on from this category is now 3 tpd, which satisfies

the SIP commitment.
