An operator that is subject to the requirements below shall also comply with all the applicab le requirements of Sections 5.0, 6.0, and 7.0. Only en gines subject to Sect ion 5.2 are eligible for inclusion in an

AECP.

8.1 During any seven (7) cons ecutive calendar day period, the operator shall operate all engines in the AECP to achieve an actual aggregate NOx emission level that is not greater than 90 percent of the NOx emissions that woul d be obtained by controlling the engines to comp ly individually with the NOx limits in Section 5.2. The operator shall operate engines in the AECP such that

AE Actual ≤ 0.90 (AE Limit )SJVUAPCD 4702 - 37 8/18/11 and shall notify the APCO wi thin 24 hours of any viol ation of this section.

8.1.1 The actual aggreg ate NOx emissions (AE Actual ) is the sum of the actual NOX emissions, over a seven (7) consecutive cal endar day period, from all engines in the AECP which were actually operated during that period.

AE Actual shall be calculated as follows:



## ) )( ( ) ( i i

where:

i identifies each engine in the AECP.

EF i is the NOx emission factor of the engine es tablished pursuant to Section 8.2 and appr oved by the APCO.

F i

is the actual total fuel used by the engine during the seven (7) consecutive calendar day period.

k i

is a constant used to convert an engine’s fuel us e and NOx emission

factor to the amount of NOx emitted. k i is dependent on the engine and the pollutant emitte d. Calculation of k i shall be accomplished using 40 CFR Part 60, Appendix A, Method 19, or an equivalent method approved by EP A, ARB and the APCO.

8.1.2 The estimated aggregate NOx emissions limit (AE Limit ) is the sum of the NOx emissions, over a seven (7) consecutive calendar day period, for the same engines in the AECP which we re actually operate d during the same period as considered in Section 8.1.1, calculated with the NOx limits of Section 5.2 and the actual fuel usage during that seven (7) consecutive calendar day period. AE Limit shall be calcula ted as follows:

AE Limit and AE Actual

.

8.2 The operator shall establish a NOx em ission factor limit fo r each engine. The

established NOx emission fact or of an engine shall be no less than the NOx

emission factor of th e engine from the most recent source test conducted pursuant to Section 6.3 and approve d by the APCO. The operator shall not operate an AECP engine in such a manner that NOx emissions exceed the established NOx

emission factor of the engine.

8.3 The operator shall submit the AECP to the APCO at leas t 18 months before compliance with the emission limits in Sect ion 5.2 is required. The AECP shall:

the NOx emission limits of this rule and any lower actual NOx emissions

will not be used to increase emission s from the same or another source.

8.3.7 Demonstrate that the engines subject to the requirements of Section 5.2 are in compliance with or on an approved schedule for compliance with all applicable District rules.

8.4 The operator shall submit an updated or modified AECP fo r approval by the APCO prior to any of the following:

8.4.1 Modification of the engine(s) which would re quire an Authority-toConstruct;

8.4.2 When new or amended rules are adopted which regulate the emissions from the engines; or

8.4.3 When the NOx emission factor established by the engine operator for an engine pursuant to Section 8.2 is modified.

8.5 In addition to the records kept pursuant to Section 6.2, the operator shall maintain records, on a daily basis, of the paramete rs needed to demonstrate compliance with the applicable NOx emission limits when operating under the AECP. These

records shall be retained for at least five years, shall be readily available, and be
