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 methods used in other media such as 

SW846 for solid waste are not automatically approved for air pollution 

applications. Submittal of test methods 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 rule 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 approved 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, attainment, RFP, or other relevant EPA 

requirements. This includes, for example, 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 development of the rule or rule changes. 

This information should explain the basis for all limits and thresholds 

contained in the rule.

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

The major affect of the amendment was to set new and lower 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 cleaning methods, particularly with vapor degreasers. (Other 

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

 Sections 305, 306, 307 and 308 listing allowable cleaning 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 standards 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 County 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 Public Hearing, thereby adopting Rule 216, Organic 

Solvent Cleaning and Degreasing Operations. 

Background:

 The proposed rule is included as a Volatile Organic Compound (VOC) control measure 

in the Sacramento Area Regional Ozone Attainment Plan, which was adopted by the 

Board on December 20, 1994. VOC emissions and 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 Ozone 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 amended 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 Rule 216 was last amended on June 8, 1995, and 

does not contain these newer proven control measures and standards. Adoption of this 

amendment will establish uniformity in the Region 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 Section 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 grams 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 operations were added, and language was revised 

for consistency. 

Section 300, Standards: 

 The rule allows for a twelve-month time period 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-month period require lower VOC content in 

solvents and are more specific in describing various categories of allowable 

equipment and cleaning methods, particularly with vapor degreasers. (Other Districts 

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

 Sections 305, 306 307 and 308 listing allowable 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 compliance standards when Emission Control 

Systems are used. 

 Section 400, Administrative Requirements: 

 All calculation formulas have been 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.

Fiscal Impacts:

 As discussed in more detail in the Staff Report, converting to aqueous degreasing 

equipment may be cost effective. The lower solvent cost will often offset the capital 

costs for the new equipment. 

California Environmental Quality Act:

 The District staff has determined that the adoption of this rule is categorically exempt 

from the California Environmental Quality Act (CEQA) requirements per the CEQA 

Guidelines, Section 15307, Actions by Regulatory 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. Notification 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 November 3, 2003 and the Roseville Tribune on 

November 5, 2003. Staff also directly contacted Safety Kleen who is the primary vendor 

for vapor degreasers in the Region. As of December 1, 2003, no comments, 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 additional businesses to be permitted, a major public 

outreach effort will be required to advise businesses of the 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 Resolution #03-19, thereby adopting amended Rule 

216, Organic Solvent Cleaning and Degreasing Operations.

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 freeboard 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 maintenance and repair of buses, aircraft, and trucks; 

cleaning of tools, machinery, equipment, 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 solvent 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 federal 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 November 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 percent per year (averaged over each consecutive 3-

year period beginning November 1993). Section 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 Reasonable Available Control Technology for major 

stationary sources.

Rule 216 

4/16/08, Page 3

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

however has a SIP commitment to reduce VOC emissions 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 the 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.” Districts 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 grams 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 similar 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 Available 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 concentrations in downwind areas. The District is an 

identified transporter of air pollutants. The regulations 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 basins or subregions that contribute to violation of 

the ambient air quality standard for ozone. The state board has identified the District as a 

transporter of air pollutants to the Upper Sacramento Valley and Broader Sacramento Area. 

Section 40910 of the California Health and Safety Code requires districts to consider full 

spectrum of emission sources and focus particular attention on reducing the emissions for 

transportation and areawide emission sources.

SUMMARY OF PROPOSED RULE REQUIREMENTS 

Proposed amendments to Rule 216 require non-vapor degreasers to use solvents with a VOC 

content of 50 grams per liter or less. The rule allows the use of solvents with VOC content higher 

than 50 grams per liter for degreasing of electronic components and other components which 

require higher VOC solvents if the solvents comply 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 consistent with the standard 

adopted by the following districts. The effective dates of the 50 grams per liter VOC limit are 

also listed in the table below:

pollution control equipment. 

RULE IMPACT ANALYSIS

Type of Sources Affected: The amended Rule 216 will affect stationary 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 operations. Staff estimates that the proposed rule 

will impact the automotive service industry the most. . Staff does not know the number of 

operations to which this rule will apply. However, 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 automotive repair and paint operations, graphic arts 

operations, and architectural paint operations that would be affected by Rule 216. Once 

this information is received, the District will 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 spent solvent for disposal. Affected sources will be required to 

replace these degreasers with new units that are designed to be used with aqueous cleaners since 

almost all of the low VOC cleaners are aqueous. Aqueous cleaners are generally made of 

concentrated alkaline detergents. They require heat 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 aqueous parts cleaner as well as cleaning 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 (Based 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 cleaners 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 concluded 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 Associates for Rule 4663, Organic Solvent, Cleaning, Storage, and 

Disposal amendments also concluded a modest impact for regional economy of the San Joaquin 

Valley. The impact on the SJVUAPCD economy was 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 contained 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 Maintenance" (publication number EPA-909-E-99-002). The 

costs comparison below is based on a case study for a typical full service automotive repair shop 

with six technicians and 14 bays. The shop purchased an aqueous spray cabinet and also an 

aqueous microbial sink-top unit. The spray cabinet 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 the 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

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 with 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.) Staff also evaluated the cost effectiveness of the 

rule and compared it with similar rules adopted 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. However, 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 reactive hydrocarbon emissions inventory for 

permitted stationary sources. Because this is such a large emission source category, it would 

be difficult or impossible to meet these requirements 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 amended rule are already in affect in many 

areas in California. The proposed lower VOC solvents limits effective on December 11, 

2004, are proven control measures that set feasible 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 subject to the provisions of the California 

Environmental Quality Act (CEQA). Staff evaluated the proposed requirements to see if 

there are any significant adverse effects on the environment. 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 Metropolitan 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. inspections) work associated with these revisions will 

be met with existing resources and planned for staff increases. 

TABLE OF FINDINGS

(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. (CHSC Section 40727(b)(1)) 

Clarity: The District must find that the rule 

is written or displayed so that its 

meaning can be easily understood 

by the persons directly affected by 

it. 

Staff has reviewed the proposed rule amendments and 

determined that they can be easily understood by 

the affected industry. In addition, the record 

contains no evidence that the persons directly 

affected by the rule can not understand it. (CHSC 

Section 40727(b)(3))

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

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 Available Control Technology (BACT) and Lowest Achievable Emission 

Rate (LEAR) that apply to solvent cleaning operations. There are also National Emission Standards for 

regulating the emissions of Hazardous air pollutants from solvent 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 requirements. The rule consistency 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 Board’s (CARB) satisfaction that it has included every 

feasible emission control measure in its plan and has an expeditious rule adoption 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 Identification of Achievable Performance Standards and 

Emerging Technologies for Stationary 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.
