Sec. 91.107  Application for certification.

    (a) For each engine family, the engine manufacturer must submit to 
the Administrator a completed application for a certificate of 
conformity, except that with respect to an existing technology OB/PWC 
engine a manufacturer may, in lieu of providing such application, submit 
to the Administrator summary testing and other information as determined 
by the Administrator.
    (b) The application must be approved and signed by the authorized 
representative of the manufacturer.
    (c) The application must be updated and corrected by amendment as 
provided in Sec. 91.122 to accurately reflect the manufacturer's 
production.
    (d) Required content. Each application must include the following 
information:
    (1) A description of the basic engine design including, but not 
limited to, the engine family specifications;
    (2) An explanation of how the emission control system operates, 
including a detailed description of all emission control system 
components (detailed component calibrations are not required to be 
included, however they must be provided if requested), each auxiliary 
emission control device (AECD), and all fuel system components to be 
installed on any production or test engine(s);
    (3) Proposed test fleet selection and the rationale for the test 
fleet selection;
    (4) Special or alternative test procedures, if applicable;
    (5) The description of the operating cycle and the service 
accumulation period necessary to break in the test engine(s) and 
stabilize emission levels and any maintenance scheduled;
    (6) A description of all adjustable operating parameters, including 
the following:
    (i) The nominal or recommended setting and the associated production 
tolerances;
    (ii) The intended physically adjustable range;
    (iii) The limits or stops used to establish adjustable ranges;

[[Page 303]]

    (iv) Production tolerances of the limits or stops used to establish 
each physically adjustable range; and
    (v) Information relating to why the physical limits or stops used to 
establish the physically adjustable range of each parameter, or any 
other means used to inhibit adjustment, are effective in preventing 
adjustment of parameters to settings outside the manufacturer's intended 
physically adjustable ranges on in-use engines;
    (7) Regarding the averaging, banking, and trading provisions, the 
information specified in Sec. 91.208;
    (8) The proposed maintenance and use instructions the manufacturer 
will furnish to the ultimate purchaser of each new engine and the 
proposed emission control label;
    (9) All test data, for HC, CO and NOX, obtained by the 
manufacturer on each test engine;
    (10) A statement that the test engine(s), as described in the 
manufacturer's application for certification, has been tested in 
accordance with the applicable test procedures, utilizing the fuels and 
equipment described in the application, and that on the basis of such 
tests the engine(s) conforms to the requirements of this part; and
    (11) An unconditional statement certifying that all engines in the 
engine family comply with all requirements of this part and the Clean 
Air Act.
    (e) At the Administrator's request, the manufacturer must supply 
such additional information as may be required to evaluate the 
application including, but not limited to, projected marine SI engine 
production.
    (f) (1) The Administrator may modify the information submission 
requirements of paragraph (d) of this section, provided the information 
specified therein is maintained by the engine manufacturer as required 
by Sec. 91.121, and amended, updated, or corrected as necessary.
    (2) For the purposes of this paragraph, Sec. 91.121(a)(1) includes 
all information specified in paragraph (d) of this section whether or 
not such information is actually submitted to the Administrator for any 
particular model year.
    (3) The Administrator may review an engine manufacturer's records at 
any time.
