PART 1048_CONTROL OF EMISSIONS FROM NEW, LARGE NONROAD 
SPARK-IGNITION ENGINES--Table of Contents
 
                    Subpart E_Testing In-use Engines
 
Sec.  1048.415  What happens if in-use engines do not meet requirements?

    (a) Determine the reason each in-use engine exceeds the emission 
standards.
    (b) If the average emission levels calculated in Sec.  1048.410(h) 
exceed any of the emission standards that apply, notify us within 
fifteen days of completing testing on this family. Otherwise follow the 
reporting instructions in Sec.  1048.420.
    (c) We will consider failure rates, average emission levels, and any 
defects--among other things--to decide on taking remedial action under 
this subpart (see 40 CFR 1068.505). We may consider the results from any 
voluntary additional testing you conduct. We may also consider 
information related to testing from other engine families showing that 
you designed them to exceed the minimum requirements for controlling 
emissions. We may order a recall before or after you complete testing of 
an engine family if we determine a substantial number of engines do not 
conform to section 213 of the Act or to this part.
    (d) If in-use testing reveals a design or manufacturing defect that 
prevents

engines from meeting the requirements of this part, you must correct the 
defect as soon as possible for any future production for engines in 
every family affected by the defect.
    (e) You may voluntarily recall an engine family for emission 
failures, as described in 40 CFR 1068.535, unless we have ordered a 
recall for that family under 40 CFR 1068.505.
    (f) You have the right to a hearing before we order you to recall 
your engines or implement an alternative remedy (see Sec.  1048.820).
