Section 250-RICR-120-05-43.9 - Compliance Demonstration

43.9.1Emissions Certification

A. An owner or operator may seek to certify that its generators meet the emission standards of this rule by providing one of the following certifications:

1. Certification by the California Air Resources Board pursuant to 17 CCR §§ 94200 through 94214, incorporated in § 43.4(B) of this Part. The certification shall be documented by providing a valid and effective Executive Order issued by the executive officer of the California Air Resources Board certifying compliance; or

2. Certification by the generator supplier stating the subject make and model of generator meets the required emission standards as supplied. This certification shall include emission test results conducted on the subject make and model of generator, including all appurtenances and equipment representative of the proposed installation, demonstrating that emissions of nitrogen oxides, particulate matter and carbon monoxide from the generator meet the emission standards in units of pounds of emissions per megawatt hour (lb/MWh) at full load design (ISO) conditions or at the load conditions specified by the applicable testing methods as follows. With respect to nitrogen oxides and carbon monoxide, test results from EPA Reference Methods, California Air Resources Board methods, or equivalent testing may be used to verify this certification. Equivalent test methods must be approved by the Office of Air Resources prior to the performance of any emission tests. When testing the output of particulate matter from liquid-fuel reciprocating engines, ISO Method 8178 shall be used, incorporated in § 43.4(C) of this Part.

B. If the design of a certified generator is modified after installation, the generator must be re-certified or be issued a minor source permit pursuant to the applicable provisions of Part 9 of this Subchapter.

C. Any engine that has been certified to meet the currently applicable US EPA non-road emissions standards set out in § 43.8.1 of this Part shall be deemed to be certified for use as an emergency generator.

D. An owner or operator shall provide calculations to demonstrate that its emergency generator or distributed generator meets the emissions standards for carbon dioxide of this rule. The calculations shall be specific to the subject make and model of generator and fuel type.

43.9.2On-site Testing

A. An owner of a generator that is not certified under the terms of § 43.9.1 of this Part will need to demonstrate compliance with the emission standards through on-site testing.

B. On-site emissions testing shall be conducted for nitrogen oxides, carbon monoxide, carbon dioxide and particulate matter no later than one hundred eighty (180) days after commencing operation.

C. An emission testing protocol shall be submitted to the Office of Air Resources for review and approval prior to the performance of any emissions tests.

D. All test procedures used for emissions testing shall be conducted in accordance with EPA Reference Methods, California Air Resources Board methods or another method approved by the Office of Air Resources prior to the performance of any emissions tests.

E. The owner/operator shall install any and all test ports or platforms necessary to conduct the required testing, provide safe access to any platforms, and provide the necessary utilities for sampling and testing equipment.

F. All testing shall be conducted under operating conditions deemed acceptable and representative for the purpose of assessing compliance with the applicable emission standards.

G. The owner/operator shall notify the Office of Air Resources at least sixty (60) days before the tests are scheduled.

H. All emissions testing must be observed by the Office of Air Resources or its authorized representatives to be considered acceptable, unless the Office of Air Resources provides authorization to the owner/operator to conduct the emission testing without an observer present.

I. A final report of the results of any on-site testing shall be submitted to the Office of Air Resources no later than sixty (60) days following completion of testing.
