(a) Tier 1 standards apply as summarized in the following table:
Table 1 to Appendix I-Tier 1 Emission Standards

| kW [GREATER THAN] 560 | 2006 | 6.4 | 3.5 | 0.20 |
(c) Tier 3 standards apply as summarized in the following table:
Table 3 to Appendix I-Tier 3 Emission Standards
[g/kW-hr]
| Rated power (kW) | Starting model year | NOX+NMHC | CO | PM |
| 37 [LESS THAN EQUAL TO] kW [LESS THAN] 75 | 2008 | 4.7 | 5.0 | 0.40 |
| 75 [LESS THAN EQUAL TO] kW [LESS THAN] 130 | 2007 | 4.0 | 5.0 | 0.30 |
| 130 [LESS THAN EQUAL TO] kW [LESS THAN EQUAL TO] 560 | 2006 | 4.0 | 3.5 | 0.20 |
(d) Tier 1 through Tier 3 standards applied only for discrete-mode steady-state testing. There were no not-to-exceed standards or transient testing.
