efforts to obtain it, then that approved method shall be installed on the ship no later than the
                   next annual survey of that ship that falls after the approved method is commercially available.

7.3     With regard to a marine diesel engine with a power output of more than 5,000 kW
                   and a per cylinder displacement at or above 90 litres installed on a ship constructed on or after
                   1  January  1990,  but  prior  to  1  January  2000,  the  International  Air  Pollution  Prevention
                   Certificate shall, for a marine diesel engine to which paragraph 7.1 of this regulation applies,
                   indicate one of the following:

.1        an approved method has been applied pursuant to paragraph 7.1.1 of this
                                     regulation;

.2   the engine has been certified pursuant to paragraph 7.1.2 of this regulation;

.3        an  approved  method  is not  yet  commercially  available as described  in
                                     paragraph 7.2 of this regulation; or

.4   an approved method is not applicable.

7.4     Subject  to  regulation  3  of  this  Annex,  the  operation  of  a  marine  diesel  engine
                   described  in  paragraph  7.1  of  this  regulation  is  prohibited,  except  when  the  emission  of
                   nitrogen oxides (calculated as the total weighted emission of NO2) from the engine is within
                   the following limits, where n = rated engine speed (crankshaft revolutions per minute):

.1      17.0 g/kWh when n is less than 130 rpm;

.2      45 · n (–0.2)  g/kWh when n is 130 or more but less than 2,000 rpm; and

.3      9.8 g/kWh when n is 2,000 rpm or more.

7.5     Certification of an approved method shall be in accordance with chapter 7 of the
                   revised NOx Technical Code 2008 and shall include verification:

.1      by the designer of the base marine diesel engine to which the approved
                                   method applies that the calculated effect of the approved method will not
                                   decrease engine rating by more than 1.0%, increase fuel consumption by
                                   more than 2.0% as measured according to the appropriate test cycle set
                                   forth in the revised NOx Technical Code 2008, or adversely affect engine
                                   durability or reliability; and

.2      that the cost of the approved method is not excessive, which is determined
                                   by a comparison of the amount of NOx reduced by the approved method to
                                   achieve the standard set forth in paragraph 7.4 of this regulation and the
                                   cost of purchasing and installing such approved method.

Certification

8       The revised NOx Technical Code 2008 shall be applied in the certification, testing and
                   measurement procedures for the standards set forth in this regulation.

9       The procedures for determining NOx emissions set out in the revised NOx Technical
                   Code 2008 are intended to be representative of the normal operation of the engine. Defeat
                   devices and irrational emission control strategies undermine this intention and shall not be
                   allowed. This regulation shall not prevent the use of auxiliary control devices that are used to
