          (c)   the following definition is added:

          ' "emission control monitoring system" means the system that ensures correct operation of the NOx control measures implemented in the engine system according to the requirements of section 6.5 of Annex I.';

        2.   in the second indent of section 6.1.5.6 'permanent emission default modes' is replaced by 'emission default modes'.

        '6.5. Requirements to ensure correct operation of NOx control measures

6.5.1.            General

6.5.1.1.        This section is applicable to compression-ignition engine systems irrespective of the technology used to comply with the emission limit values provided in the tables in section 6.2.1.

6.5.1.2.        Application dates

The requirements of sections 6.5.3, 6.5.4 and 6.5.5 shall apply from 9 November 2006 for new type approvals and from 1 October 2007 for all registrations of new vehicles.

6.5.1.3.        Any engine system covered by this section shall be designed, constructed and installed so as to be capable of meeting these requirements over the useful life of the engine.

6.5.1.4.        Information that fully describes the functional operational characteristics of an engine system covered by this section shall be provided by the manufacturer in Annex II.

6.5.1.5.        In its application for type-approval, if the engine system requires a reagent, the manufacturer shall specify the characteristics of all reagent(s) consumed by any exhaust aftertreatment system, e.g. type and concen- trations, operational temperature conditions, reference to international standards etc.

6.5.1.6.        Subject to requirements set out in section 6.1, any engine system covered by this section shall retain its emission control function during all conditions regularly pertaining in the territory of the Community, especially at low ambient temperatures.

6.5.1.7.        For the purpose of type-approval, the manufacturer shall demonstrate to the Technical Service that for engine systems that require a reagent, any emission of ammonia does not exceed, over the applicable emissions test cycle, a mean value of 25 ppm.

6.5.1.8.        For engine systems requiring a reagent, each separate reagent tank installed on a vehicle shall include means for taking a sample of any fluid inside the tank. The sampling point shall be easily accessible without the use of any specialised tool or device.

              6.5.2.            Maintenance requirements

              6.5.2.1.
