Vapor Recovery Certification Procedure

CP-206

Certification Procedure for Vapor Recovery Systems

At Gasoline Dispensing Facilities Using

Aboveground Storage Tanks

A set of definitions common to all certification and test procedures are in:

D-200 Definitions for Vapor Recovery Procedures

All section references are to the Health and Safety Code unless otherwise stated.

1. GENERAL INFORMATION AND APPLICABILITY

This document describes the procedure for evaluating and certifying Aboveground 

Storage Tanks (AST), Standing Loss Control, Phase I and Phase II vapor recovery 

systems, and components, used at Gasoline Dispensing Facilities (GDF). An ARB 

Executive Order certifying the system shall be issued only after all of the applicable 

certification requirements have been successfully completed.

This Certification Procedure, CP-206, is adopted pursuant to Section 41954 of the 

California Health and Safety Code (CH&SC) and is applicable to vapor recovery 

systems installed at GDFs using an AST for controlling gasoline vapors emitted during 

diurnal venting (Standing Loss Control), the re-fueling of aboveground storage tanks 

(Phase I), and the refueling of vehicle fuel tanks (Phase II). Vapor recovery systems 

are complete systems and components that shall include all associated ASTs, 

dispensers, piping, nozzles, couplers, processing units, and any other equipment or 

components necessary for Standing Loss Control or the control of gasoline vapors 

during Phase I or Phase II refueling operations at GDFs.

Below-grade vaulted tanks shall be certified under Certification Procedure,

CP-201, as incorporated by reference in California Code of Regulations, Title 17,

section 94011. 

1.1 Requirements of Other State Agencies

As required pursuant to sections 41955 and 41957 of the CH&SC, the Executive 

Officer shall coordinate this Certification Procedure with:

1.1.1 Department of Food and Agriculture,

Division of Measurement Standards (DMS)

1.1.2 Department of Forestry and Fire Protection

Office of the State Fire Marshal (SFM) 

California Air Resources Board April 23, 2015

CP-206, page 1
1.1.3 Department of Industrial Relations, Division of Occupational Safety and 

Health (DOSH)

Prior to certification of the vapor recovery system by the Executive Officer, the 

applicant shall submit plans and specifications for the system to each of these 

agencies. Certification testing by these agencies may be conducted concurrently 

with ARB certification testing; however, the approval of the SFM, DMS, and 

DOSH shall be a precondition to certification by ARB. The applicant is 

responsible for providing documentation of these approvals to ARB.

1.2 Requirement to Comply with All Other Applicable Codes and Regulations

Certification of a system by the Executive Officer does not exempt the system 

from compliance with other applicable federal, state, and local codes and 

regulations. 

1.3 System Certification Matrix

The Certification Procedure is designed to provide system and component 

certifications and Executive Orders with options for levels of controls as specified 

in CP-206 or as requested by the applicant. The varying levels of control can be 

achieved through combinations of Standing Loss Control, Phase I and Phase II 

vapor recovery systems, certified independently or together, according to the 

matrix in Table 1-1. An applicant shall specify the certification matrix to be tested 

in the application. Compatibility between Standing Loss Control, Phase I, and/or 

Phase II vapor recovery systems shall be evaluated per Table 1-1.

CP-206, page 3
2.1 Performance Standards

A performance standard defines the minimum performance requirements for 

certification of any system, including associated components. An applicant 

may request certification to a performance standard that is more stringent 

than the minimum performance standard specified in CP-206. Ongoing 

compliance with all applicable performance standards, including any more 

stringent standards requested by the applicant, shall be demonstrated 

throughout certification testing.

2.2 Performance Specifications

A performance specification is an engineering requirement that relates to the 

proper operation of a specific system or component thereof. In addition to the 

performance specifications mandated in CP-206, an applicant may specify 

additional performance specifications for a system or component. An 

applicant may request certification to a performance specification that is more 

stringent than the minimum performance specification in CP-206. Ongoing 

compliance with all applicable performance specifications, including any more 

stringent specifications requested by the applicant, shall be demonstrated 

throughout certification testing.

2.3 Innovative System 

The innovative system concept provides flexibility in the design of vapor 

recovery systems. A vapor recovery system that fails to comply with an 

identified performance standard or specification may qualify for consideration 

as an innovative system, provided that the system meets the primary 

emission factor/efficiency, complies with all other applicable requirements of 

certification, and the Executive Officer determines that the emission benefits 

of the innovation are greater than the consequences of failing to meet the 

identified standard or specification.

2.4 Additional or Amended Performance Standards or Performance 

Specifications

Whenever these Certification Procedures are amended to include additional 

or amended performance standards, any system that is certified as of the 

effective date of additional or amended standards shall remain certified until 

the operative date. Systems installed before the operative date of additional 

or amended standards may remain in use for the remainder of their useful life 

or for up to four years after the effective date of the new standard, whichever 

is shorter, provided the requirements of Section 20 are met.

Whenever these Certification Procedures are amended to include additional 

or amended performance specifications, a system shall remain certified until 

the Executive Order expiration date. A system that was installed before the 

operative date of additional or amended performance specifications may 

remain in use subject to the requirements of Section 18. 

California Air Resources Board April 23, 2015

standards and specifications contained herein are specified in

Table 2-1.

2.4.2 The operative dates of performance standards shall be the effective 

date of adoption of amended or additional performance standards, 

except as otherwise specified in Table 2-1. Certifications shall 

terminate on the operative date of amended or additional performance 

standards unless the Executive Officer determines that the system 

meets the amended or additional performance standards or 

specifications. Upon the operative date of the amended or additional 

performance standards, only systems complying with the amended or 

additional performance standards may be installed. 

2.4.3 The operative dates of performance specifications are listed in 

Table 2-1. As of the operative date of amended or additional 

performance specifications, only systems complying with the amended 

or additional performance specifications may be installed.

2.4.4 The performance standards and specifications of this Certification 

Procedure are not required for any tank that was installed and 

operated before April 1, 2009 and is located in an area that is classified 

by the U. S. Environmental Protection Agency as being in attainment 

with the federal 8-hour ozone standard. If such tanks are equipped 

with a Phase I vapor recovery system listed in Table 2-2, such system 

shall continue to be used unless replaced by a system that meets the 

performance standards or specifications of this Certification Procedure. 

Replacement parts for systems listed in Table 2-2 shall be subject to 

the requirements of section 2.4.6. If the area where the tank is located 

is reclassified as no longer in attainment with the Federal 8-hour ozone 

standard, such tank must be brought into compliance with applicable 

performance standards and specifications within four years of the date 

of reclassification.

2.4.5 Notwithstanding any other provision in this Certification Procedure, 

tanks installed and operated before April 1, 2009 that meet any of the 

following criteria (summarized in Table 2-3) may continue using a 

Phase I vapor recovery system that has been certified by ARB under 

one of the Executive Orders listed in Table 2-2 until the end of that 

system’s useful life:

a) The tank is located in an area that is determined to be in 

Extreme nonattainment with the federal 8-hour ozone standard, 

and is in a rural air district, and has an annual gasoline 

throughput of less than 18,000 gallons per year; or

b) The tank is located in an area that is determined to be in

the coaxial hose can be cleared through natural drainage into the vehicle. In 

the case of top-mounted, side-mounted, and ground-mounted dispensers, 

natural drainage will be determined at a distance of 24 inches and a height of 

30 inches from the outside plane of the dispenser. 

5.12 Vapor Return Piping

The requirements of Sections 5.12.1 through 5.13.2 for the vapor return 

piping and, if applicable, condensate traps, from the dispenser riser to the 

aboveground storage tank, shall apply to any facility installed after 

January 1, 2009.

5.12.1 The vapor return piping from any fueling point to the aboveground 

storage tank shall be free of liquid or fixed blockage.

5.12.2 The Phase II riser shall have a minimum nominal internal diameter of 

one inch (1” ID). The connection between the Phase II riser and the 

dispenser shall be made with materials listed for use with gasoline, and 

shall have a minimum nominal 1” ID.

5.12.3 For remote dispensers, vapor return piping shall have a minimum 

nominal internal diameter of three inches (3” ID) from the point of the 

first manifold to the storage tank. Existing facilities operating prior to 

January 1, 2009, shall be required to meet the minimum three inch 

diameter standard only upon facility modifications requiring exposing at 

least 50 percent of the underground vapor return piping.

5.12.4 Wherever feasible, the recommended minimum downward slope of the 

vapor return piping, from the remote dispensers to the tank, shall be at 

least one-fourth (1/4) inch per foot of run. The minimum downward 

slope, in all cases, shall be at least one-eighth (1/8) inch per foot of 

run. 

5.12.5 The vapor return piping shall be constructed of rigid piping (any piping 

material with a bend radius that exceeds six feet; the maximum 

allowable deflection distance is 9 5/8 inches, as determined by TP201.2G, Bend Radius Determination for Underground Storage Tank 

Vapor Return Piping), or shall be contained within rigid piping, or shall 

have an equivalent method, approved by the Executive Officer, to 

ensure that proper slope is achieved and maintained. (Note: this does 

not apply to flexible connectors at potential stress points, such as 

storage tanks, dispensers, and tank vents.) Rigidity shall be 

determined in accordance with TP-201.2G.

Liquid condensate traps (also known as knockout pots and thief ports) are 

used to keep the vapor return piping from the remote dispenser to the 

aboveground storage tank clear of any liquid blockage.

5.13.1 Liquid condensate traps shall be used only when the minimum slope 

requirements of 1/8 inches per foot of run cannot be met due to the 

topography.

5.13.2 When condensate traps are installed, they shall be: 

(a) certified by ARB; 

(b) maintained vapor tight; 

(c) accessible for inspection upon request; 

(d) capable of automatic evacuation of liquid; and

(e) equipped with an alarm system in case of failure of the 

evacuation system.

5.14 Connections and Fittings

All connections, fittings, emergency vents, tank gauges, components, and 

auxiliary fittings not specifically certified with an allowable leak rate shall not 

leak. The absence of vapor leaks may be verified by the use of commercial 

liquid leak detection solution, or by bagging when the vapor containment 

space of the aboveground storage tank is subjected to a non-zero gauge 

pressure. (Note: leak detection solution will detect leaks only when positive 

gauge pressure exists.) The absence of liquid leaks may be verified by visual 

inspection for seepage and drips.

purpose of demonstrating compatibility, as required by Sections 5.5 and 5.6, as 

well as to insure that the Phase I and SLC systems are functioning properly during 

the Phase II certification test. Any Phase I or SLC components identified as not 

performing correctly shall be replaced and the Phase II system certification 

continued. However, Phase II system test data collected during any period 

associated with a Phase I or SLC system test failure shall be evaluated for validity.

During Phase II system certifications, failure of any Phase I or SLC components 

that are determined to be unrelated to the performance of the Phase II system 

shall not be cause for termination of the Phase II system certification. During 

Phase II certification tests, if any Phase I or SLC component is identified as having 

performance deficiencies, then a more thorough investigation of the Phase I or 

SLC component/system performance will be initiated by the Executive Officer.

During Phase II system certification, any Phase I or SLC system and/or component 

performance deficiencies that are determined to be related to the performance of 

the Phase II system shall be cause for termination of the Phase II system 

certification, as provided by Sections 5.5 and 5.6.

14.1 Test Site for Field Testing of Vapor Recovery Systems

The applicant shall make arrangements for the appropriate vapor recovery 

system to be installed on one or more ASTs that do not transfer gasoline for 

standing loss control certification testing, or on one or more GDFs for Phase I 

or II system certification testing. The applicant shall request, in writing, 

approval of the AST or GDF as a test site from the Executive Officer. Upon 

determining that the GDF meets all of the following criteria, the Executive 

Officer shall, in writing, designate the selected location as a test site, and 

exempt it from any state or local district prohibition against the installation of 

uncertified vapor recovery equipment. This shall not exempt it from the 

prohibition against the offer for sale, or sale, of uncertified equipment. The 

vapor recovery system shall be installed throughout the entire facility (note 

this requirement applies to the primary certification test site). The Executive 

Officer may require that the system be installed in more than one facility for 

the purpose of testing.

that location. The applicant shall be responsible for any additional 

costs, such as travel, associated with that location.

14.1.3 Continuous access to the aboveground storage tank or test site by 

ARB staff, without prior notification, shall be provided. Every effort will 

be made to minimize inconvenience to the owner/operator of the 

facility. If testing deemed necessary cannot reasonably be conducted, 

the facility shall be deemed unacceptable and the test shall be 

terminated. 

14.1.4 If test status is terminated for any reason, uncertified equipment shall 

be removed within sixty (60) days, unless the Executive Officer 

extends the time in writing. The local district with jurisdiction over the 

facility may impose a shorter time.

14.1.5 All test data collected by the applicant at the test site shall be made 

available to the Executive Officer within fifteen (15) working days. 

Continuous data, such as temperature monitoring data, shall be 

submitted in bimonthly increments within fifteen (15) days of the last 

day of the increment. Failure to provide this information may result in 

extension or termination of the test. The Executive Officer may specify 

the format in which the data is to be submitted.

14.1.6 Test site designation may be requested by the applicant, or by another 

person, for facilities other than the certification test site(s), for the 

purpose of research and development, or independent evaluation of a 

system prior to its certification. Approval of such a test site shall be at 

the discretion of the Executive Officer. The test site shall be subject to 

all of the above conditions with the exception of 14.1.1 and 14.1.2.

14.1.7 For testing conducted pursuant to Sections 19 and 20, SLC or Phase I 

certification test sites configured with fewer than three P/V valves may 

be approved by the Executive Officer

14.1.8 Phase II certification test sites will be configured with one to three P/V 

vent valves, each with an associated ball valve.

duration of the SLC system operational test is specified in section 3.2.

14.3.2 No maintenance shall be performed other than that which is specified 

in the installation, operation, and maintenance manual. Such 

maintenance as is routine and necessary shall be performed only after 

approval by the Executive Officer. Occurrences beyond the 

reasonable control of the applicant, such as vandalism or accidental 

damage by customers (e.g., drive-offs), shall not be considered cause 

for failure of the systems.

14.3.3 Except where it would cause a safety problem, maintenance shall not 

be performed until approval by the Executive Officer has been 

obtained. In those situations that require immediate action to avoid 

potential safety problems, maintenance may be performed immediately 

and the Executive Officer shall be notified as soon as practicable

thereafter and provided with a narrative of the reasons giving rise to 

the maintenance and the nature of the maintenance performed. 

14.3.4 For the purpose of SLC system certification, the temperature in the 

AST and ambient temperature shall be monitored and recorded 

continuously throughout the operational test in accordance with 

TP-206.1. 

14.3.5 Tests of the performance of the system and/or components shall be 

conducted periodically throughout the operational test period. If the 

results of such tests, when extrapolated through the end of the 

warranty period, show a change that result in the degradation of a

California Air Resources Board April 23, 2015

CP-206, page 51
allowed during the operational test only when the Executive Officer has 

determined that the testing does not affect the normal operation of the 

system.

14.4.2 Challenge Mode Testing

Testing to verify that the system meets the applicable standards under 

various GDF operating conditions may be conducted as part of 

certification testing. Challenge mode tests may be allowed during the 

operational test only when the Executive Officer has determined that 

the testing does not affect the normal operation of the system.

14.5 Efficiency and/or Emission Factor Test

Testing to determine the efficiency and/or emission factor of the vapor 

recovery system shall be conducted in accordance with the applicable test 

procedures specified in Section 3, 4, or 5 of this procedure. Additional testing 

may be required if the Executive Officer deems it necessary. The additional 

testing may include, but is not limited to the determination of the Reid Vapor 

Pressure of the fuel, the volume and/or mass in the vapor return path, fuel 

and/or tank temperature, and the uncontrolled emission factor. 

14.5.1 Standing Loss Systems. A test of the static pressure integrity of the 

Phase I system shall be conducted, in accordance with TP-206.3, no 

less than 24 hours or more than seven days prior to conducting 

TP-206.1 or TP-206.2. The static pressure integrity test shall be 

conducted not more than 48 hours after the completion of these tests 

as well. Failure of the static pressure integrity test shall invalidate the 

TP-206.1 or TP-206.2 test results unless the Executive Officer

determines that the integrity failure did not result in any significant 

unmeasured emissions.

14.5.2 Phase I Systems. A test of the static pressure integrity of the Phase I 

system shall be conducted, in accordance with TP-206.3, no less than 

24 hours or more than seven days prior to conducting TP 206.4 or 

TP-201.1A. Testing, in accordance with TP 206.4 and/or TP-201.1A, 

shall be conducted at delivery rates typical and representative of the 

facilities for which certification is requested. More than one test may 

be required to accomplish this determination. Certification may be 

limited to specified maximum loading rates. The static pressure 

integrity of the vapor recovery system shall be verified as soon as 

possible, but not more than 48 hours, after the completion of this test. 

Failure of the static pressure integrity test shall invalidate the TP 206.4

or TP-201.1A test results unless the Executive Officer determines that 

the integrity failure did not result in any significant unmeasured 

emissions.

14.5.3 Phase II Systems. A test of the static pressure integrity of the Phase II 

system shall be conducted, in accordance with TP-206.3, no more than 

seven days and no less than three days prior to conducting TP-201.2. 

California Air Resources Board April 23, 2015

CP-206, page 52
The static pressure integrity of the vapor recovery system, including all 

test equipment installed for the purpose of conducting TP-201.2, shall 

be verified as soon as possible, but not more than 48 hours, after the 

completion of this test. Failure of the static pressure integrity test shall 

invalidate the TP-201.2 test unless the Executive Officer determines 

that the integrity failure did not result in any significant unmeasured 

emissions.

14.6 Vehicle Matrix

A representative matrix of 30 non-ORVR vehicles shall be used when testing 

to determine the Phase II efficiency for the performance standard. The 

composition of the representative vehicle matrix shall be determined for each 

calendar year by the Executive Officer in accordance with TP-201.2A 

(Determination of Vehicle Matrix for Phase II Systems).

14.6.1 Vehicles will be tested as they enter the dispensing facility ("first in" 

basis) until a specific matrix block of the distribution is filled.

14.6.2 The Executive Officer may exclude any vehicle that fails to comply with 

the vehicle fill pipe specifications (“Specifications for Fill Pipes and 

Openings of Motor Vehicle Fuel Tanks” incorporated by reference in 

title 13, CCR, Section 2235).

14.6.3 The Executive Officer may exclude a vehicle prior to its dispensing 

episode only if such exclusion and its reason is documented; e.g. 

unusual facility conditions beyond the applicant's control or unusual 

modifications to the vehicle. All data required by the test procedure 

shall be taken for such vehicles for subsequent review and possible 

reversal of the exclusion decision made during the test. The only other 

reasons for excluding a vehicle from the test fleet are incomplete data 

or the factors in TP-201.2.

14.6.4 Additional vehicles may be chosen for testing at the test site by the 

Executive Officer. The vehicles shall be chosen, according to the 

Executive Officer's judgment, so that any of the first 30 non-ORVR

vehicles, which may later be found to have invalid data associated with 

them, shall have replacements from among the additional vehicles on 

a "first in" basis.

14.6.5 A matrix of fewer than 30 non-ORVR vehicles may be made by 

deleting up to a maximum of two vehicles by reducing the 

representation in any cell or combination of cells of the vehicle matrix, 

subject to the following requirements for each candidate reduced cell.

(a) No cell shall be reduced by more than one vehicle 

(b) At least one dispensing episode has already been tested in 

each cell.

California Air Resources Board April 23, 2015

CP-206, page 53
(c) None of the other dispensing episodes in the cell have yielded 

field data which, in the Executive Officer's judgment, would 

cause a failure to meet the standards specified in Section 5.1. 

(d) All tested dispensing episodes in all cells have yielded field

data that, in the Executive Officer's judgment, would yield valid 

test results after subsequent review and evaluation.

15. ALTERNATE TEST PROCEDURES AND INSPECTION PROCEDURES

Test procedures other than those specified in this Ccertification Pprocedure shall 

be used only if prior written approval is obtained from the Executive Officer. A test 

procedure is a methodology used to determine, with a high degree of accuracy, 

precision, and reproducibility, the value of a specified parameter. Once the test 

procedure is conducted, the results are compared to the applicable performance 

standard to determine the compliance status of the facility. Test procedures are 

subject to the provisions of Section 41954(h) of the H&SC.

15.1 Alternate Test Procedures for Certification Testing

The Executive Officer shall approve, as required, those procedures necessary 

to verify the proper performance of the system.

15.2 Request for Approval of Alternate Test Procedure

Any person may request approval of an alternative test procedure. The 

request shall include the proposed test procedure, including equipment 

specifications and, if appropriate, all necessary equipment for conducting the 

test. If training is required to properly conduct the test, the proposed training 

program shall be included. 

15.3 Response to Request

The Executive Officer shall respond within fifteen (15) days of receipt of a 

request for approval and indicating that a formal response will be sent within 

sixty (60) days. If the Executive Officer determines that an adequate 

evaluation cannot be completed within the allotted time, the Executive Officer 

shall explain the reason for the delay, and will include the increments of 

progress such as test protocol review and comment, testing, data review, and 

final determination. If the request is determined to be incomplete or 

unacceptable, Executive Officer shall respond with identification of any 

deficiencies. The Executive Officer shall issue a determination regarding the 

alternate procedure within sixty (60) days of receipt of an acceptable request. 

15.4 Testing of Alternate Test Procedures

All testing to determine the acceptability of the procedure shall be conducted 

by ARB staff, or by a third party responsible to and under the direction of 

ARB. Testing shall be conducted in accordance with the written procedures 

and instructions provided. The testing shall, at a minimum, consist of nine 

California Air Resources Board April 23, 2015

CP-206, page 54
sets of data pairs, pursuant to USEPA Reference Method 301, “Field 

Validation of Pollutant Measurement Methods from Various Waste Media”, 40 

CFR Part 63, Appendix A, (December 29, 1992). Criteria established in 

USEPA Reference Method 301 shall be used to determine whether 

equivalency between the two test methods exists. For situations where 

method 301 is not directly applicable, the Executive Officer shall establish 

equivalence based on the concepts of comparison with the established 

method and statistical analysis of bias and variance. Method Approval of the 

procedure shall be granted, on a case-by-case basis, only after all necessary 

testing has been conducted. Because of the evolving nature of technology 

and procedures for vapor recovery systems, such approval may or may not 

be granted in subsequent cases without a new request for approval and 

additional testing to determine equivalency. If, after approval is granted, 

subsequent information demonstrates that equivalency between the two 

methods no longer meets the USEPA Method 301 requirements, the 

Executive Officer shall revoke the alternate status of the procedure.

15.5 Documentation of Alternate Test Procedures

Any such approvals for alternate test procedures and the evaluation testing 

results shall be maintained in the Executive Officer's files and shall be made 

available upon request. Any time an alternate procedure and the reference 

procedure are both conducted and yield different results, the results 

determined by the reference procedure shall be considered the true and 

correct results.

15.6 Inspection Procedures

Inspection procedures are methodologies that are developed to determine 

compliance based on applicable performance standards or specifications. 

Inspection procedures are typically, but not necessarily, parametric in nature 

and possess a built-in factor of safety, usually at least twice the applicable 

standard or specification. Inspection procedures are not subject to Section 

41954(h) of the H&SC. 

Upon submittal of an inspection procedure to CARB, the Executive Officer 

shall respond within thirty (30) days, providing the applicant with a 

determination of the applicability of Section 41960.2(d) or Section 41960.2(e) 

of the H&SC.

16. DOCUMENTATION OF CERTIFICATION

Documentation of certification shall be in the form of an Executive Order listing the 

criteria requirements of installation and operation of a certified system. The 

Executive Officer shall issue an Executive Order of Certification only to those 

applicants or manufacturers who have demonstrated full compliance with these 

certification procedures and the ability to maintain such compliance as provided 

herein.

California Air Resources Board April 23, 2015

certification Executive Order shall specify the date on which the certification 

shall expire if it is not renewed as specified in Section 18. 

17.2 One Vapor Recovery System per AST System

No more than one certified Phase II vapor recovery system may be installed 

on each aboveground storage tank (AST) system unless the Phase II system 

has been specifically certified to be used in combination. For facilities with 

dedicated vapor piping, each aboveground storage tank and associated 

dispensing points shall be considered an AST system, and different AST 

systems may have different vapor recovery systems. For facilities with 

manifolded vapor piping connecting storage tanks, all the manifolded tanks 

and associated dispensing points are considered one AST system, and only 

one certified Phase II vapor recovery system may be installed in conjunction 

with that AST system.

17.3 Certification Not Transferable

California Air Resources Board April 23, 2015

CP-206, page 56
Upon successful completion of all the requirements, certification shall be 

issued to the company or individual requesting certification, as the Executive 

Officer deems appropriate. If the ownership, control or significant assets of 

the certification holder are changed as the result of a merger, acquisition or 

any other type of transfer, the expiration date of the certification shall remain 

unchanged. However, no person shall offer for sale, sell, or install any 

system or component covered by the certification unless the system or 

component is recertified under the new ownership, or, in the case of a 

component, is otherwise certified. Systems installed prior to the transfer shall 

be subject to the specifications contained in Section 20 of this procedure.

17.4 Financial Responsibility

The adequacy of the (1) methods of distribution, (2) replacement parts 

program, (3) financial responsibility of applicant and/or manufacturer, (4) 

trained network of service technicians available at a reasonable cost to the 

consumer and (5) other factors affecting the economic interests of the system 

purchaser shall be evaluated by the Executive Officer and determined to be 

satisfactory to protect the purchaser and respond to warranty claims. A 

determination of financial responsibility by the Executive Officer shall not be 

deemed to be a guarantee or endorsement of the manufacturer or applicant.

If no system has yet been certified that meets additional or amended 

performance standards and specifications, as provided in Section 2.4, the 

applicant is also requested to provide evidence of the commitment of financial 

investors for the commercial manufacture of the system, a projected market 

demand of the system as milestones for implementation of the plan, an

inventory of equipment ready for shipment and a list of suppliers and 

subcontractors which are part of the manufacturing plan.

17.5 Warranty

all applicable requirements. The Executive Officer may require the 

inclusion of additional procedures.

17.6.2 No changes shall be made to ARB Approved Manuals without the 

Executive Officer’s prior written approval.

17.7 Identification of System Components

17.7.1 All components for vapor recovery systems shall be permanently 

identified with the manufacturer’s name, part number, and, if 

applicable, a unique serial number. This requirement does not apply to 

replacement subparts of the primary component. Specific components 

may be exempted from this requirement if the Executive Officer 

determines, in writing, that this is not feasible or appropriate.

California Air Resources Board April 23, 2015

CP-206, page 58
17.7.2 Nozzle serial numbers shall be permanently affixed to, or stamped on, 

the nozzle body and easily accessible for inspection. The location of 

the serial number shall be evaluated and approved by the Executive 

Officer prior to certification.

17.8 Compliance Enforcement

The Executive Officer may, upon complaint or upon his or her own initiative, 

cause the review, inspection and/or testing of any component subject to 

certification under this Certification Procedure in any manner deemed 

necessary to determine ongoing compliance with Certification Procedure 

requirements and standards. Upon a determination of noncompliance based 

on sufficient data and documentation, the certification holder shall bear the 

costs incurred during component review, inspection and/or testing.

17.9 Revocation of Certifications

The certification of any system determined not to be achieving the applicable 

performance standards and specification listed in CP-206 may be revoked. 

The Executive Officer may conduct testing for the purpose of investigation of 

or verification of potential system deficiencies

Revoked systems may remain in use for the remainder of their useful life or 

for up to four years after the revocation, whichever is shorter, provided they 

comply with all of the requirements of Section 20. Systems with revoked 

certifications shall not be installed on new installations or major modifications 

of existing installations.

18. CERTIFICATION RENEWAL

At least eighteen (18) months prior to expiration of the certification period, the 

applicant may request to renew the certification. System certifications shall be 

renewed without additional testing if no data demonstrating system deficiencies is 

found or developed prior to the expiration date. During the four-year certification 

period, system deficiencies shall be identified through periodic equipment audits, 

complaint investigations, certification or compliance tests, surveys, or other 

sources of information. If deficiencies are documented, they shall be resolved to 

the satisfaction of the ARB Executive Officer or the certification shall expire. The 

ARB Executive Officer may extend certification if resolution of system deficiencies 

appears likely or if additional time is required to gather and evaluate information.

The renewal process, along with the sections of this document that describe them, 

are outlined below.

(a) Request for Renewal Section 18.1

(b) Review of the Request Section 18.2

(c) Evaluation of System Deficiencies Section 18.3

(d) Letter of Intent Section 18.4

(e) Renewal of Executive Order Section 18.5

( f) Denial of Executive Officer Approval Section 18.6

California Air Resources Board April 23, 2015

CP-206, page 59
If no request for renewal is received by the ARB within eighteen (18) months of the 

certification expiration date, the Executive Officer shall send a “Notice of Pending 

Expiration” to the holder of the Executive Order. Table18-1 provides an estimated 

timeline for the renewal process. The timeline is intended to serve as a guide to 

provide approximate target schedules for completion of steps in the renewal 

process. If the Executive Officer fails to send a Notice of Pending Expiration, the 

failure to send such notice does not serve to extend the certification expiration 

date.

Each applicant submitting a certification renewal request shall be charged fees not 

to exceed the actual cost of evaluating and/or testing the system to determine 

whether it qualifies for renewal. Refer to Section 11.1 for more information on Fee 

Payment.

shall solicit information on system or component deficiencies through 

equipment audits, complaint investigations, certification or compliance tests, 

surveys, VRED data (if applicable), and any deficiencies identified by District 

staff, or other sources of information. The Executive Officer may conduct 

testing to investigate and/or verify system or component deficiencies. Testing 

to evaluate component modifications, VRED lists (if applicable), to 

demonstrate compatibility, or for challenge mode determinations, will be 

subject to the applicable sections of CP-206. If potential deficiencies are 

noted, an evaluation will be conducted to determine if:

18.3.1 The deficiency has been or is in the process of being resolved;

18.3.2 System/component modification(s) are necessary;

18.3.3 Executive Order modifications are necessary;

18.3.4 Additional testing is required.

18.4 Letter of Intent

(1) renew the Executive Order or (2) allow the Executive Order to expire. 

Conditions for expired certifications are discussed in Section 19 of this 

Certification Procedure. The letter of intent should be issued prior to the 

Executive Order expiration date but will not be issued prior to completion of 

the evaluation process described in Sections 18.1, 18.2, and 18.3. If the 

evaluation process is not complete and the letter of intent is not issued prior 

to the expiration date then the Executive Officer may determine that 

installation of the system at new facilities or major modifications will not be 

allowed during the extension period.

The Executive Officer may allow a certification extension if:

18.4.1 Resolution is likely but renewal time is insufficient; or

18.4.2 Additional time is necessary to gather and evaluate information.

18.5 Renewal of Executive Order

Executive Orders approved for renewal shall be valid for a period of four (4) 

years.

California Air Resources Board April 23, 2015

CP-206, page 61

CP-206, page 62
(d) Letter of Intent Section 19.4

(e) Issuance of Executive Order Section 19.5

19.1 Request for Amendment

The request for amendment shall be written and signed by an authorized 

representative of the applicant, and shall include the items listed below:

19.1.1 Executive Order to be amended;

19.1.2 Description of change;

19.1.3 Changes to the Executive Order such as:

(a) System or component drawings

(b) Installation, Operations, and Maintenance Manual

(c) Fuel and System Compatibility

19.1.4 Agency approvals or determinations (to be submitted prior to approval 

of EO amendment, see Section 1.1);

19.1.5 Updates to the training program;

19.1.6 Applicable information specified in Section 12 ; and

19.1.7 Other information such as the Executive Officer may reasonably 

require.

19.2 Review of the Request

Requests for alternate or replacement components, equipment 

reconfigurations, or software changes will be subjected to an engineering 

evaluation to determine the level of testing required. The Executive Officer 

may require full operational testing of at least 180 days (30 days for Standing 

Loss Controls that attenuate temperature), allow abbreviated and/or limited 

operational testing, or determine that a component modification does not 

affect the performance of the vapor recovery system and therefore no testing 

is required. 

General criteria to be considered when determining the level of testing are as 

follows:

(a) extent of physical changes to the component;

(b) extent of material changes to the component;

(c) changes that may affect the durability of the component;

(d) whether performance specifications are the same;

(e) similarity of system designs (i.e. for component transfers); and

(f) information from previous certification testing.

California Air Resources Board April 23, 2015

CP-206, page 63
19.2.1 Modified Components

Modified components (i.e., any changes made to vapor recovery 

components certified as part of a system) may be certified if testing 

demonstrates that performance standards and specifications will 

continue to be achieved. The level and duration of operational and/or 

other testing will be determined by the Executive Officer based on an 

engineering evaluation. 

19.2.2 Transfer of Components from Another Certified System

Components certified with a system may subsequently be considered 

for use with another certified system design provided that the 

performance standards and specifications of the components, as 

specified in the application for the system, are equivalent. 

Performance standards and specifications, and compatibility, are to be 

verified by testing and/or engineering evaluation.

Abbreviated/limited operational testing may be considered since the 

component has previously undergone 180-day/full certification testing 

as part of another system. 

19.2.3 New Component(s) that have not been Previously Certified on a 

System.

Components that have not previously been certified with a system, 

whether for use as an alternate or replacement component, shall be 

required to undergo operational testing of at least 180 days. Limited 

operational testing may be considered for such components, if 

determined to be appropriate by the Executive Officer.

19.2.4 Components that do not affect the performance of the vapor recovery 

system.

Certification shall not be required for components, either new or 

modified, determined by the Executive Officer not to affect the 

performance of the vapor recovery system. An engineering evaluation 

shall be conducted to document that the change will not affect the 

performance of the vapor recovery system. The Executive Officer shall 

notify the applicant in writing of the determination. However, in some 

cases, such as when a part number changes, an amendment to the 

Executive Order may be required. 

19.2.5 Other Amendments to Executive Orders

(a) System Configurations

Alternative configurations of components of a certified system 

may be considered for certification based on limited and 

abbreviated testing. Examples of alternative system 

California Air Resources Board April 23, 2015

CP-206, page 64
configurations include dual fill or remote fill for Phase I and 

processor placement or vapor piping options for Phase II.

(b) Software Updates

Software revisions of previously certified software components 

may be considered for certification with limited and/or abbreviated 

testing. The software change may be approved with no testing if 

the Executive Officer finds that the software modifications do not 

affect the vapor recovery system or in-station diagnostic system 

performance.

19.3 Testing

System or component modifications shall be subjected to sufficient 

operational, challenge mode, and/or VRED testing to verify the performance 

and durability of the modified system relative to the certified system that was 

originally tested. 

The level of operational testing to be required is determined as outlined in 

Section 19.2. Normally, full operational testing of at least 180 days (30 days 

for Standing Loss Controls that attenuate temperature) is required. 

Abbreviated and/or limited operational tests may be allowed in some cases, 

at the discretion of the Executive Officer. If operational tests are abbreviated, 

the minimum duration (and gasoline throughput requirement) will be specified 

by the Executive Officer. The test procedure and test frequency 

requirements for limited operational tests will be specified by the Executive 

Officer.

If operational testing is required, then the applicant will choose an 

appropriate test site meeting the requirements of Section 14.1. The applicant 

shall submit sufficient information to demonstrate that the requirements of 

Section 12.8 are met. 

19.4 Letter of Intent

A letter shall be sent to the applicant stating the Executive Officer’s intent to 

either issue the amended Executive Order or deny the request.

19.5 Issuance of Executive Order

The original expiration date shall be maintained for all Executive Order 

amendments unless a renewal, as described in Section 18, is specifically 

requested and approved.

Previous versions of the Executive Order are superseded, as discussed in 

Section 20.

California Air Resources Board April 23, 2015

CP-206, page 65
20. REPLACEMENT OF COMPONENTS OR PARTS OF A SYSTEM WITH A 

TERMINATED, REVOKED, SUPERSEDED, OR EXPIRED CERTIFICATION

This section applies to systems for which the certification was terminated, revoked, 

superseded, or has expired. Systems that were installed as of the operative date 

of a new standard, or that are otherwise subject to Health and Safety Code Section

41956.1, may remain in use for the remainder of their useful life or for up to four (4)

years after the effective date of the new standard or the date of revocation, 

whichever is shorter, provided they comply with all of the specifications of this 

section. Installed systems that have superseded or expired Executive Orders, 

unless renewed in accordance with Section 18, may remain in use for up to four (4) 

years after the expiration date of the Executive Order, provided they comply with 

all the specifications of Section 20.

20.1 Component and Replacement Parts

 Components and replacement parts meeting the currently and prospectively 

operative performance standards or specifications may be approved for use 

as a replacement part with the no-longer-certified system for the remainder 

of the allowable in-use period of the system.

 When an approved, compatible component or replacement part that meets 

the operative standards or specification is determined to be commercially 

available, only that component or replacement part shall be installed except 

as permitted by section 20.2. Approval shall not require the replacement of 

already-installed equipment prior to the end of the useful life of that part or 

component. The approved replacement component shall be considered to 

be commercially available if that component can be shipped within three 

weeks of the receipt of an order by the manufacturer of the component.

20.2 Component or Replacement Part Not Meeting Specifications

A component or replacement part not meeting the currently operative 

performance standards or specifications, but which was certified for use with 

the system, may be used as a replacement only under either of the following 

circumstances:

(a) no compatible component or part that meets the new standards or 

specifications has been approved as a replacement part, or

(b) during a reasonable time period specified by the Executive Officer to 

allow for the sell-through of existing inventory of previously certified 

components or replacement parts.

20.3 Component or Part Not Certified with System and Not Meeting 

Specifications

A component or part that was not certified for use with the system, and that 

does not meet all of the currently operative standards or specifications may
