The direct measurement and monitoring method should be documented
in an on-board monitoring manual based on these Guidelines. The manual
should be submitted to the Administration for approval. The approval
reference of that manual should be entered under section 3 of the
Supplement to the EIAPP Certificate. The Administration may issue
a new EIAPP Certificate, with the details in section 3 of the Supplement
duly amended, if the method is approved after the issue of the first
EIAPP Certificate, i.e. following the pre-certification survey.
