Current through Register 2024 Notice Reg. No. 36, September 6, 2024

Section 93115.13 - ATCM for Stationary CI Engines - Compliance Demonstration

(a) Upon approval by the District APCO, the following sources of data may be used in whole or part to demonstrate compliance with the emissions standards or requirements of sections 93115.6 through 93115.9:

(1) off-road engine certification test data for the stationary diesel-fueled CI engine,

(2) engine manufacturer test data,

(3) emissions test data from a similar engine,

(4) emissions test data used in meeting the requirements of the Verification Procedure for the emission control strategy implemented, or

(5) An alternative compliance demonstration as described in section 93115.13(f).

(b) Emissions testing of a stationary diesel-fueled CI engine, for purposes of showing compliance with the requirements of sections 93115.6 through 93115.9, shall be done in accordance with the methods specified in section 93115.14.

(c) For purposes of emissions testing, the particulate matter (PM) emissions from a dual-fueled stationary CI engine, which uses as its fuel a mixture of diesel fuel and other fuel(s), shall be deemed to be 100% diesel PM.

(d) Emissions testing for the purposes of determining the percent change from baseline shall include baseline and emission control strategy testing subject to the following conditions:

(1) Baseline testing may be conducted with the emission control strategy in place, provided the test sample is taken upstream of the emission control strategy and the presence of the emission control strategy is shown to the District APCO's satisfaction as having no influence on the emission test results;

(2) Control strategy testing shall be performed on the stationary diesel-fueled CI engine with full implementation of the emission control strategy;

(3) The percent change from baseline shall be calculated as the baseline emissions minus control strategy emissions, with the difference being divided by the baseline emissions and the result expressed as a percentage; and

(4) The same test method shall be used for determining both baseline emissions and control strategy emissions.

(e) Emission testing for the purposes of demonstrating compliance with an emission level shall be performed on the stationary diesel-fueled CI engine with the emission control strategy fully implemented.

(f)Alternative Compliance Demonstration: The owner or operator of a new or in-use stationary diesel-fueled CI engine greater than 50 bhp may demonstrate compliance with the 0.01 g/bhp-hr PM emission standard of sections 93115.6 through 93115.9 by using one of the following:

(1) A Level 3 Verified Diesel Emission Control Strategy in combination with a certified CI engine that meets the 0.15 g/bhp-hr PM emission standard, or

(2) An 85 percent PM emission reduction control strategy in combination with a certified CI engine that meets 0.15 g/bhp-hr PM emission standard, or

(3) A certified CI engine that meets the 0.15 g/bhp-hr PM emission standard in combination with one of the emission control strategies identified in section 93115.13(f)(1) or (f)(2) and meets the requirements of section 93115.3(u), or

(4) Off-road CI equipment manufactured in compliance with the Transitional Implementation Flexibility Provisions for Equipment Manufacturers specified in title 13, CCR, section 2423(d); title 40 CFR, section 89.102(d); or title 40, CFR, section 1039.625 in combination with one of the emission control strategies identified in sections 93115.13(f)(1) or (f)(2) provided the CI engine meets the 0.15 g/bhp-hr PM emission standard, or

(5) A certified CI engine in an engine family identified by the manufacturer to participate in the averaging, banking, or trading program for that model year in compliance with the applicable subparts of title 40, CFR, section 89; title 40, CFR, section 1039; or title 13, CCR, section 2423(b)(2), provided the CI engine meets the 0.15 g/bhp-hr PM emission standard and is used in combination with one of the emission control strategies identified in sections 93115.13(f)(1) or (f)(2), or

(6) A Tier 4 certified CI engine or a new piece of equipment identified in section (f)(4) that emits no more than 0.015 g/bhp-hr PM.
