         6.2.1.1                          Engines need not comply with the oxides of nitrogen and particulate limits specified in 86.007-11 (a)(1), paragraphs (i)(A) and (iv)(A), respectively, provided the emissions of oxides of nitrogen and particulates from the engine do not exceed the limits specified for the transient test under either Option 1 or Option 2 in Table 1 when tested in accordance with the transient test cycle specified in Subpart N 86.1333-2007.

         6.2.1.2                          Engines need not comply with the weighted average emission limits specified in 86.007-11 (a)(3)SET(i), provided the emissions of oxides of nitrogen and particulates from the engine do not exceed the limits specified for the steady state test under either Option 1 or Option 2 in Table 1 when tested to the supplemental emissions test specified in Subpart N 86.1360-2007.
