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 major affect of the amendment was to set new and lo wer VOC limits for non-vapor degreasing of 50 grams VOC per

liter or less. Other amendments were:

Section 200, Definitions:  Numerous new control devices and operations were added, and language was revised for consistency.

 Standards effective after the twelve-month period require lower VOC content in solvents and are more specific in describing various categories of allowable equipment and cleani ng methods, particularly with vapor degreasers. (Other

Districts have found that lowe r VOC-content materials are now readily available.)

 Sections 305, 306, 307 and 308 listing allowable cleani ng materials, methods and equipment were updated for

clarification.

 Section 309 lists alternate compliance standards when Airtight/Airless Cleaning Systems are used.

 Section 310 discusses alternate compliance st andards when Emission Control Systems are used.

Section 400, Administrative Requirements:

 All calculation formulas were relocated from Section 200 to this Section. Section 403, Operation and Maintenance Plan was revised for clarity.

Section 500, Monitoring and Records:  Recordkeeping requirements were rearranged and expanded as necessary, due to the increased number and type of materials discussed in the rule. Additional test methods and protocol items were added to this
Section.

### MEMORANDUM

TO: Board of Directors, Placer C ounty Air Pollution Control District

FROM: Todd K. Nishikawa, Principal Air Pollution Control Engineer

AGENDA DATE: December 11, 2003

SUBJECT: Approval of Resolution #03-19, adopting Rule 216, Organic Solvent Cleaning and Degreasing Operations (Action/Public Hearing)

Action Requested :

Approve Resolution #03-19, in a Pub lic Hearing, thereby adopting Rule 216, Organic Solvent Cleaning and Degreasing Operations

.

Background:

The proposed rule is included as a Volati le Organic Compound (VOC) control measure in the Sacramento Area Regional Ozone Atta inment Plan, which was adopted by the Board on December 20, 1994. VOC emissions a nd Oxides of Nitrogen (NOx) emissions are precursors to the photochemical formation of Ozone. The Attainment Plan was adopted in response to the 1990 Amendments to the Federal Clean Air Act (CAA), which required areas designated “serious” for Oz one by the United States Environmental Protection Agency (USEPA), to submit a State Implementation Plan (SIP) revision. The

District met the 1994 Plan’s SIP commitment for the adoption of a surface preparation and cleanup solvent rule when an ame nded Rule 216 was adopted on June 8, 1995.

Discussion:

The main purpose of the proposed amendment to Rule 216 is to add control measures and standards now in effect in equivalent rules in other districts, such as Sacramento, San Joaquin and South Coast. The present Ru le 216 was last amende d on June 8, 1995, and does not contain these newer pr oven control measures and sta ndards. Adoption of this amendment will establish uniformity in the Re gion in the control of Volatile Organic Compound (VOC) emissions from this stationary source category.

It is estimated that an addition reduction of 0.37 tons VOC per day can be achieved from the adoption and implementation of the proposed amendments to Rule 216.Rule 216, Organic Solvent Cleaning and Degreasing Operations

PCAPCD Board of Directors Agenda Date: December 11, 2003 Page 2



### The proposed rule amendment applies to solvent cleaning operations, anywhere in Placer County, performed in non-vapor degreasers and vapor degreasers. Partial or complete exemptions are allowed in numerous cases as listed in Sect ion 104 of the rule.

The major affect of the proposed amendments is to set new and lower VOC limits for non-vapor degreasing of 50 gram s VOC per liter or less. These lower limits are consistent with the limits currently in place in Sacramento and other jurisdictions and are proven to be feasible. The lower VOC limits and other new requirements do not become

effective for 12 months. Other amendments are:

Section 200, Definitions:

 Numerous new control devices and operat ions were added, and language was revised for consistency.

Section 300, Standards:

 The rule allows for a twelve-month time pe riod after adoption to provide sources the time to implement methods and equipment to meet the more stringent and complete requirements contained in Sections 302.2, 303.2 and 304.

 Standards effective after the twelve-m onth period require lower VOC content in solvents and are more specific in desc ribing various categ ories of allowable equipment and cleaning methods , particularly with vapor de greasers. (Other Districts

have found that lower VOC-content mate rials are now readily available.)

 Sections 305, 306 307 and 308 listing allowa ble cleaning materials, methods and equipment have been updated for clarification.

 Section 309 lists alternate compliance standards when Airtight/Airless Cleaning Systems are used.

 Section 310 discusses alternate complia nce standards when Emission Control Systems are used.

Section 400, Administ rative Requirements:

 All calculation formulas have been relo cated from Section 200 to this Section. Section 403, Operation and Maintenan ce Plan was revised for clarity.

Section 500, Monitoring and Records:

 Recordkeeping requirements were rearranged and expanded as necessary, due to the increased number and type of materials discussed in the ru le. Additional test methods and protocol items were added to this Section.Rule 216, Organic Solvent Cleaning and Degreasing Operations

PCAPCD Board of Directors Agenda Date: December 11, 2003 Page 3



### Fiscal Impacts:

As discussed in more detail in the Sta ff Report, converting to aqueous degreasing equipment may be cost effective. The lowe r solvent cost will often offset the capital costs for the new equipment.

California Environmental Quality Act:

The District staff has determined that the ad option of this rule is categorically exempt from the California Environmental Quality Act (CEQA) requirements per the CEQA Guidelines, Section 15307, Actions by Regulat ory Agencies for Protection of Natural

Resources.

Public Outreach:

A public workshop was held on November 19, 2003 at the Placer County Planning

Commission Chambers in Auburn. Notifica tion for this workshop was done through direct mailing to those possibly affected by this rule and also through public notices printed in the Auburn Journal on Novemb er 3, 2003 and the Roseville Tribune on November 5, 2003. Staff also directly contac ted Safety Kleen who is the primary vendor for vapor degreasers in the Region. As of December 1, 2003, no comment s, either oral or written, have been received.

Because the requirements of Rule 216 apply to many uses that are not permitted by the District, as well as requiring some additiona l businesses to be permitted, a major public outreach effort will be require d to advise businesses of th e requirements of the amended

rule. The effective date of December 11, 2004, following adoption is an unusually long period to provide for this outreach and any operations changes necessary for compliance.

Recommendation:

District staff recommend approval of Re solution #03-19, thereby adopting amended Rule 216, Organic Solvent Cleaning and Degreasing Operations

.

## STAFF REPORT

Rule 216, Organic Solvent Cleani ng and Degreasing Operations

December 11, 2003

### Attachment A Rule Consistency Matrixes

Rule 216 4/16/08, Page 2

BACKGROUND

The District is proposing to amend Rule 216, Organic Solvent Cleaning and Degreasing Operations. This rule regulates VOC emissions from solvent degreasing operations. Rule 216 was first adopted on June 19, 1979 and last amended on June 8, 1995. Rule 216 is being amended in order to require non-vapor degreasing operations (also referred to as cold degreasing) to be preformed using cleanup material that contains no more than 50 grams per liter of VOCs. The proposed amendments also allow the use of an air pollution control device or airtight/airless cleaning system as an alternative to complying with the 50 grams per liter VOC limit. A detailed list of the proposed changes to the rule is included as Attachment C to this staff report.

There are two types of degreasing operations regulated under Rule 216; vapor and non-vapor degreasing. In vapor degreasing the solvent is heated to enhance the degreasing process. Different controls such as a refrigerated freeboa rd chiller and a carbon adsorption system are used to minimize the emissions of VOCs from vapor degreasers. Non-vapor degreasing uses solvents at room temperature. Non vapor degreasers are commonly used by manufacturing operations and the automotive service industry. The degreaser and the solvent are usually provided through a service agreement. The spent solvents are also taken by the solvent supplier and usually are recycled for reuse. The solvent recycling process is usually performed outside the District (Based on conversation with Safety Kleen.) Different methods of cleaning are discussed below.

Maintenance and Repair Cleaning: This type of cleaning is performed to keep equipment, tools, machinery, and general work area in a good condition. Examples of such cleaning include cleaning of engines and other parts during maintena nce and repair of buses, aircraft, and trucks; cleaning of tools, machinery, equipm ent, and general work areas in shops.

Manufacturing Cleaning: Manufacturing cleaning includes cleaning of manufactured parts during various stages of production processing such as cutting, machining, molding, and fabricating, and assembling of manufactured parts. The cleaning is used to remove and contaminants such as cutting oil and grease.

Solvent Flushing: Solvent flushing is generally used for cleaning of ink, coating, and adhesive application equipment. The discharged solv ent is usually collected in containers.



### LEGAL MANDATES

Federal Mandate: The Sacramento Region has been designated as a severe nonattainment area for the federal ozone standard by the EPA. There are legal mandates that directly resulted from this classification. Section 182 (c) of the fede ral Clean Air Act Amendments of 1990 (42 U.S.C. 7511a (c)) required all ozone nonattainment areas classified as “serious” and above to submit a State Implementation Plan (SIP) revision by No vember 15, 1994 which described, in part, how the area will achieve: (i) the National Ambient Air Quality Standard for ozone, and (ii) actual VOC emission reductions of at least three pe rcent per year (averaged over each consecutive 3- year period beginning November 1993). Sec tion 182(d) (42 U.S.C. 7511a (d)) requires the District to adopt the control measures proposed in the SIP. In addition, Section 172 (c)(1) (42 U.S.C. 7502) requires the District to adopt R easonable Available Control Technology for major stationary sources.

### Attachment A Rule Consistency Matrixes

Rule 216 4/16/08, Page 3

This rule is not included in the Sacramento Ar ea Regional Ozone Attainment Plant. The District,

however has a SIP commitment to reduce VOC em issions from surface preparation and cleanup. The District adopted Rule 240, Surface Preparation and Cleanup to meet this requirement, but

there is still a shortfall in VOC emission reductions from this category. Amending Rule 216 will generate additional VOC emission reductions that can be used to make up for the shortfall in VOC emission reductions from the Surface Preparation and Cleanup control category.

State Mandates: The District is designated serious nonattainment for the state ozone standard. The California Clean Air Act requires areas with this designation to adopt control measures required in Sections 40913, 40914, and 40919 of th e California Health and Safety Code (CHSC):

All Feasible Measures Requirements: Section 40914 requires each district plan to demonstrate that the plan includes “every feasible measure.” Di stricts must adopt the most effective control

measures to reduce VOC emissions from solvent cleaning and degreasing operations. Many Districts such as SCAQMD, SMAQMD, BAAQMD, and SJVUAPCD have adopted regulations that require the use of a 50 gram s per liter VOC-containing solvent for general cleaning. The SCAQMD has also revised their rule to require the use of cleanup materials with VOC content of 25 grams per liter (Effective January 1, 2003.) Staff evaluated the standards in the proposed rule against sim ilar applicable requirements adopted by these districts. The results are included as Attachment B to the Staff Report.

Best Available Retrofit Requirements: Section 40919 requires districts with serious nonattainment for ozone to adopt Best Availabl e Retrofit Control Technology (BARCT) for all existing sources. BARCT means an emission limitation that is based on the maximum degree of reduction achievable, taking into account environmental, energy, and economic impacts by each class or category of sources (CHSC Section 40406). Staff has found that the proposed VOC requirements meet the BARCT requirement and therefore the proposed rule meets the requirements of CHSC Section 40919.

Transport Mitigation Requirements: Title 17, California Code of Regulations, Section 70600 requires districts within the areas of origin of transported air pollutants, to include sufficient control measures in their attainment plans for ozone to mitigate the impact of pollution sources within their jurisdictions on ozone concentrati ons in downwind areas. The District is an identified transporter of air pollutants. The regula tions require the District's plan must contain at minimum requirements for BARCT for source categories that collectively amount to 75% of the 1987 actual VOC and NOx emissions inventory.

Section 39610 of the California Health and Safety Code requires the state board to identify air basins that transport air pollutants to other air basi ns or subregions that contribute to violation of the ambient air quality standard for ozone. Th e state board has identified the District as a transporter of air pollutants to the Upper S acramento Valley and Broader Sacramento Area.

Section 40910 of the California Health and Safe ty Code requires districts to consider full spectrum of emission sources and focus particul ar attention on reducing the emissions for transportation and areawide emission sources.

Rule 216 4/16/08, Page 4

SUMMARY OF PROPOSED RULE REQUIREMENTS

Proposed amendments to Rule 216 require non-va por degreasers to use solvents with a VOC content of 50 grams per liter or less. The rule a llows the use of solvents with VOC content higher than 50 grams per liter for degreasing of elect ronic components and other components which require higher VOC solvents if the solvents comp ly with the VOC limits in Rule 240. The amendments also include increasing the freeboard ratio for vapor degreasers from 0.75 to 1.0, adding new control requirements for vapor degreasers, and operating requirements applicable to

remote reservoir cleaners. A list of all of the proposed changes to Rule 216 is included as Attachment C to the staff report. The proposed VOC standard is consiste nt with the standard adopted by the following districts. The effec tive dates of the 50 grams per liter VOC limit are

also listed in the table below:

RULE IMPACT ANALYSIS

Type of Sources Affected : The 

### amended Rule 216 will affect statio nary sources that use non-vapor degreasers as part of their cleaning operations. Degreasers (also known as part cleaners) are widely used by automotive repair shops, manufacturing operations, small printing shops, electric and electronic components repair and manufacturing facilities, and miscellaneous repair and maintenance operation s. Staff estimates that the proposed rule will impact the automotive service industry th e most. . Staff does not know the number of operations to which this rule will apply. Ho wever, many operations will be regulated only through the rule (i.e. no permits will be issued). As a result a significant public education and outreach effort to affected operators will be necessary, and this is one reason for the

### Attachment A Rule Consistency Matrixes

Rule 216 4/16/08, Page 5

unusually long 12 months between rule adoption and the effective date of the new provisions. The District has requested but has not yet received information from the Department of Consumer Affairs on automoti ve repair and paint operations, graphic arts operations, and architectural paint operations th at would be affected by Rule 216. Once this information is received, the District w ill seek to advise and educate solvent users regarding the requirements of Rule 216 and other applicable District rules.

Impact on Regional Economy: Staff analyzed the impact of the proposed requirements on

sources in the District. Almost all of the facilities are currently using solvent type parts cleaners. These cleaners are usually leased for a monthly fee. The leasing company usually supplies the solvent and also picks up the sp ent solvent for disposal. Aff ected sources will be required to replace these degreasers with new units that are desi gned to be used with aqueous cleaners since almost all of the low VOC cleaners are aque ous. Aqueous cleaners are generally made of concentrated alkaline detergents. They require h eat in order to effectively clean the parts. The spent solvent will also have to be disposed through a certified waste recycler. There are many suppliers available that supply a queous parts cleaner as well as clea ning materials. The cost of a part cleaner varies depending on the manufacturer and the capacity of the cleaner. The disposal cost is about $275 to $350 per drum of waste (Ba sed on cost disposal information from Mr. Glen Brown, General Manager, River City Painting.) A Cost effectiveness analysis comparing the cost of solvent part cleaners and aqueous part cleaner s showed cost savings for affected business (See tables in Section Range of Probable Costs Due to Rule 216).

Socioeconomic Impact Analysis Performed by other Districts: The SCAQMD evaluated the economical impacts of their Rule 1171 using an economic policy model, the REMI (Regional Economic Modeling) model and c oncluded that their Rule 1171 would not have an adverse impact on the economy in the SCAQMD (Final Staff Report for Rule 1171, Solvent Cleaning Operations, July 1991.) The study concluded that approximately four jobs will be created annually in directly regulated sources. A more recent SJVUAPCD socioeconomic impact study prepared by Jack Faucett Associ ates for Rule 4663, Organic So lvent, Cleaning, Storage, and Disposal amendments also concluded a modest impact for regional economy of the San Joaquin Valley. The impact on the SJVUAPCD economy wa s an employment change of two jobs. Staff expects no impact from the new regulations on employment in the District.

Range of Probable Cost due to Rule 216 Amendment for Proposed 50 Grams per Liter

VOC Limit: The cost for using solvents and aqueous cleaners are summarized in the table below.

These costs are based on cost information contai ned in an EPA Region IX pollution prevention program fact sheet titled "Aqueous Part Cleanings". This fact sheet is part of a package fact

sheets entitled either "The Pollution Prevention Tool Kit, Best Environmental Practices for Auto Repair" (publication number EPA-909-E-99-001) or The Pollution Prevention Tool Kit, Best

Environmental Practices for Fleet Maintenan ce" (publication number EPA-909-E-99-002). The costs comparison below is based on a case study fo r a typical full service automotive repair shop with six technicians and 14 bays. The shop purc hased an aqueous spray cabinet and also an aqueous microbial sink-top unit. The spray cabin et solution and sludge were disposed of as separate waste streams every 6 months by a waste disposal company. The microbial unit did not require solution disposal in over 16 months of use. The majority of cost savings were in cleaning

labor.

Note: The cost analysis above is based on replacing th e two solvent units with two aqueous units (one of the aqueous units also uses microbes to aid in the cleaning Process.) The analyses show that adding microbes to the aqueous unit reduces the operating cost significantly since heating of the solution in

h i i d d

### Attachment A Rule Consistency Matrixes

Rule 216 4/16/08, Page 7

As seen the in the tables above, using aqueous cleaners resulted in cost savings for this shop.

Staff also analyzed the cost impact from raising the freeboard ratio for vapor degreasers from 0.75 to one and the new additional equipment requirements. Additional costs to affected businesses may include the cost of complying w ith the new recordkeeping requirements for solvent usage since many businesses are not required to do so at this time. This cost will vary depending on the number of part cleaners at the facility.

Availability/Cost Effectiveness of Alternatives to Rule 216: Staff evaluated all of the VOC limits adopted by other districts and chose this limit since it has been demonstrated to be technologically feasible (see Attachment B.) Sta ff also evaluated the cost effectiveness of the rule and compared it with similar rules adop ted by other Districts (see Attachment B.) One alternative to the amended rule is to adopt the solvent cleaning regulations adopted by other districts. The other alternative is not to adopt it. This would require replacement of

lost emission reductions from other sources. Ho wever, the District is required by state law (see discussion under Mandates) to adopt BARCT for source categories that collectively amount to 75 percent of the 1987 actual react ive hydrocarbon emissions inventory for permitted stationary sources. Because this is su ch a large emission source category, it would be difficult or impossible to meet these requi rements without this rule. Additionally, the District is required by federal law to adopt RACT for major stationary sources.

Emission Reduction Potential for Rule 216: The District estimates that 0.37 tons per day of

VOC emission reductions will be achieved from the proposed regulation. The VOC emission reductions were estimated based on the year 2005 planning inventory (forecasted from Central California Ozone Study (CCOS) Inventory) (See Attachment D).

Necessity of Amending Rule 216: (See discussion under Legal Mandates Section)

OTHER FACTORS:

Technological Feasibility: The VOC limits proposed for Rule 216 for cleaning materials are based on requirements adopted and implemented by BAAQMD, SCAQMD, SMAQMD, and SJVUAPCD. Therefore, the proposed VOC limits are technologically feasible.

Enforceability: Reporting requirements and testing procedures have been included in the rule to increase enforceability.

Public Acceptability: The requirements outlined in this amende d rule are already in affect in many areas in California. The proposed lower VO C solvents limits effective on December 11, 2004, are proven control measures that set feas ible VOC standards for solvent cleaning and degreasing. The adoption of limits equal to Sacramento and other areas also levels the business “playing field” within the region.

ENVIRONMENTAL REVIEW AND COMPLIANCE The proposed amendments to Rule 216 are s ubject to the provisions of the California Environmental Quality Act (CEQA). Staff eval uated the proposed requirements to see if there are any significant adverse effects on the en vironment. Staff has concluded that based on the findings of air quality impact analysis performed by the staff of Sacramento Metropolitan Air Quality Management District (Initial Study, Amendments to Rule 454, and Adoption of Rule 466, Sacramento Metr opolitan Air Quality Management District ; April 2002) that there will be no significant impact on the environment from the

amendments to this rule.



### DISTRICT IMPACTS

Additional permitting and compliance (e.g. inspecti ons) work associated with these revisions will be met with existing resources a nd planned for staff increases.

TABLE OF FINDINGS

Six Required Findings: According to Section 40727(a) of the California Health & Safety Code, prior to adopting or amending a rule or reg ulation, an air district’s board must make findings of necessity, authority, clarity, cons istency, non-duplication, and reference. The findings must be based on the following:

1. Information presented in the District’s written analysis (see Appendix A), prepared pursuant to Health and Safety Code Section 40727.2,

2. Information contained in the rulemaking records pursuant to Section 40728 of the Health and Safety Code, and

3. Relevant information presented at the Board’s hearing for the rule.

(Continued next page)

### Attachment A Rule Consistency Matrixes

Rule 216 4/16/08, Page 9

The table below sets the findings and the basis for making the finding.

FINDING FINDING DETERMINATION
Authority: The District must find that a provision of law or of a state or federal regulation permits or requires the District to adopt, amend, or repeal the rule. The District is authorized to adopt rules and regulations by California Health and Safety Code, Sections 40001, 40702, 40716, 41010 and 41013. (CHSC Section 40727(b)(2))

Necessity: The District must find that the rulemaking demonstrates that a need exists for the rule, or for its amendment or repeal. Proposed amendments to Rule 216 are necessary in order to meet the Federal Clean Air Act Reasonably Available Control Technology requirements (Sections 182(b)(2) and 172(c)(1) (42 U.S.C. 7502 of the Federal Clean Air Act Amendments of 1990),

the state’s Best Available Retrofit Control Technology requirements (CHSC Section 40919(a)(3)), and “all feasible measures” requirement (CHSC Section 40914) for reducing volatile organic compound emissions from solvent cleaning operations. (CHS C Section 40727(b)(1)) Clarity: The District must find that the rule is written or displayed so that its meaning can be ea sily understood by the persons directly affected by

it. Staff has reviewed the prop osed rule amendments and determined that they can be easily understood by the affected industry. In addition, the record

contains no evidence th at the persons directly affected by the rule can not understand it. (CHSC Section 40727(b)(3)) Consistency: The rule is in harmony with,

and not in conflict with or contradictory to, existing statutes, court decisions, or state or federal regulations. The proposed rule amendments do not conflict with and are not contradictory to, ex isting statutes, court decisions, or state or federal regulations. (CHSC Section 40727(b)(4))

Non-Duplication: The District must find that either: 1) The rule does not impose the same requirements as an existing state or federal regulation; or 2) that the duplicative requirements are necessary or proper to execute the powers and duties granted to, and imposed upon

the District. The proposed rule amendments do not duplicate any state laws or regulations, regarding the attainment and maintenance of state and federal air quality standards. (CHSC Section 40727(b)(5))

Reference: The District must refer to any statute, court decision, or other provision of law that the District implements, interprets, or makes specific by adopting, amending or repealing the rule. CHSC Sections 40913, 40914 and 40919(a)(3), 41010.

Additional Informational Requirements (CHSC Section 40727.2): In complying with

CHSC Section 40727 .2, the District must identify all federal requirements and District rules that apply to the same equipment or source type as the proposed rule or

amendments. The discussion attached (A ttachment A-1) contains a comparison of other requirements that apply to solvent cleaning operations.

Rule 216 4/16/08, Page 10

Attachment A Rule Consistency Analysis

Proposed amendments to Rule 216 will limit the VOC emissions from solvent cleaning operations. There

are EPA standards such as Best Av ailable Control Technology (BACT) and Lowest Achievable Emission Rate (LEAR) that apply to solvent cleaning operatio ns. There are also National Emission Standards for regulating the emissions of Hazardous air pollutants from solv ent cleaning operations. This regulation is 40 CFR Part 63 Subpart T – Halogenated Solvent Emissions from Solvent Cleaning. Rule 216 exempts solvent degreasing operations regulated under 40 CFR Part 63 Subpart T from their requirements. Therefore, Rule 216 does not duplicate NESHAP requi rements. The rule cons istency matrixes for Rule

216 are listed below in Attachments A-1.

IDENTIFICATION OF ACHIEVABLE PERFORMANCE STANDARDS AND EMERGING

TECHNOLOGIES FOR SOLVENT CLEANING

The California Clean Air Act requires districts unable to achieve five percent annual emission reductions

to demonstrate to the California Air Resources Boar d’s (CARB) satisfaction that it has included every feasible emission control measure in its plan and has an expeditious rule adopti on schedule. According to CARB, no district has been able to demonstrate five percent (5%) annual reduction in ozone precursors. Therefore, every district’s plan is evaluated on the basis of demonstrating adoption of “Every Feasible

Measure.”

CARB has used the definition for “feasible” from the California Environmental Quality Act (CEQA) (14 California Code of Regulations, Section 15364). CEQA defines "feasible" as: “capable of being accomplished in a successful manner within a reasonable period of time, taking into account economic, environmental, legal, social, and technological factors.” According to CARB the adoption of every feasible measure involves the adoption of regulations that have been successfully implemented elsewhere. CARB’s interpretation is explained at length in Iden tification of Achievable Performance Standards and Emerging Technologies for Sta tionary Sources, March 1998.

On the following page, the District compares the requirements in Rule 216 with other with similar rules adopted by SCAQMD, SMAQMD, and SJVUAPCD.
