PART 1048_CONTROL OF EMISSIONS FROM NEW, LARGE NONROAD SPARK-IGNITION 

ENGINES--Table of Contents

 

                Subpart D_Testing Production-line Engines

 

Sec.  1048.301  When must I test my production-line engines?





    (a) If you produce engines that are subject to the requirements of 

this part, you must test them as described in this subpart.

    (b) We may suspend or revoke your certificate of conformity for 

certain engine families if your production-line engines do not meet the 

requirements of this part or you do not fulfill your obligations under 

this subpart (see Sec. Sec.  1048.325 and 1048.340).

    (c) Other requirements apply to engines that you produce. Other 

regulatory provisions authorize us to suspend, revoke, or void your 

certificate of conformity, or order recalls for engines families without 

regard to whether they have passed these production-line testing 

requirements. The requirements of this part do not affect our ability to 

do selective enforcement audits, as described in part 1068 of this 

chapter. Individual engines in families that pass these production-line 

testing requirements must also conform to all applicable regulations of 

this part and part 1068 of this chapter.

    (d) You may ask to use an alternate program for testing production-

line engines. In your request, you must show us that the alternate 

program gives equal assurance that your production-line engines meet the 

requirements of this part. If we approve your alternate program, we may 

waive some or all of this subpart's requirements.

    (e) If you certify an engine family with carryover emission data, as 

described in Sec.  1048.235(c), and these equivalent engine families 

consistently pass the production-line testing requirements over the 

preceding two-year period, you may ask for a reduced testing rate for 

further production-line testing for that family. The minimum testing 

rate is one engine per engine family. If we reduce your testing rate, we 

may limit our approval to any number of model years. In determining 

whether to approve your request, we may consider the number of engines 

that have failed the emission tests.

    (f) We may ask you to make a reasonable number of production-line 

engines available for a reasonable time so we can test or inspect them 

for compliance with the requirements of this part. See 40 CFR 1068.27.
