                             Applicant Guidance for
                  Technical/Engineering Hardship Relief Requests
                             Under 40 CFR 1039.625
Background

TPEM provisions (40 CFR 1039.625) allow nonroad equipment manufacturers to exempt part or
all of their production from Tier 4 standards for a period of up to 7 years
    o  Use of provisions limited to those entities that have primary responsibility for designing
       and manufacturing equipment and whose manufacturing procedures include installing
       some engines in the equipment
    o  One exemption or allowance per engine power category is allocated to each
       manufacturer
           •    If manufacturer is a subsidiary of a parent company, the allowance is allocated
               to the parent and must be shared across the parent and all subsidiaries
Nonroad equipment manufacturers can apply for additional exemptions above and beyond the
standard TPEM allowance due to technical or engineering hardship (40 CFR 1039.625(m))

Technical/Engineering Hardship Relief (40 CFR 1039.625(m))

Allows EPA to approve additional exemptions if extreme and unusual circumstances that are
clearly outside of the equipment manufacturer's control and that could not have been avoided
with reasonable discretion have resulted in technical or engineering problems that prevent
them from meeting regulatory requirements
    o  Please note that a merger of two companies, or an acquisition of one company by
       another, where the previously separate companies would have been eligible for
       separate TPEM allowances, does not alone qualify as an extreme and unusual
       circumstance outside the control of the resulting parent company - such a circumstance
       would not meet the regulatory criteria for hardship relief
    o  If a company is experiencing technical or engineering circumstances creating hardship,
       those may be appropriate for the Agency to consider in determining whether to grant
       hardship relief
Request needs to be sent to the Designated Compliance Officer before a violation of TPEM
requirements occurs:

-------
       Only available to equipment manufacturers not also producing engines for their equipment
       Must use up standard TPEM allowances under 40 CFR § 1039.625(b)(l) or (2) before using any
       additional allowances
       Additional allowances must be used within the specified seven-year period of 40 CFR §
       1039.625(a)
       For manufacturers using the percent-of-production allowance under 40 CFR § 1039.625(b)(l)
           o  Additional allowances may not exceed 200 percent for each power category (this is on
              top of the 80 percent already allowed under TPEM for a combined maximum of 280
              percent)
       For manufacturers using the small volume allowance under 40 CFR § 1039.625(b)(2)
           o  Additional allowances may not exceed 2,000  units (this is on top of the  small volume
              allowance already allowed under TPEM)
           o  Alternatively, may waive annual limits specified in 40 CFR § 1039.625(b)(2) instead of or
              in addition to increasing the total number of allowances
III.     Application
       Include all of the information requested per 40 CFR § 1039.625(m)(2)(i) through (ix)

                  •    Original plan/schedule for managing redesign of equipment with standard TPEM
                      allowance under 40 CFR § 1039.625(b)(l) or (2)
                  •    Revised plan/schedule clearly identifying unusual events/circumstances outside
                      of manufacturer's control and the resulting delay on redesign of equipment1
           o  The 12-character EPA engine family name for:
                  •    The TPEM engine for which you are  requesting additional allowances
                  •    The Tier 4-compliant engine for which you  are attempting to redesign your
                      equipment
           o  Market place information, including the following:
                  •    Major competitors in market segment

                  •    Projected production volumes for the years in which hardship is anticipated
           o  Estimate of when you will exhaust your current TPEM allowance
           o  Documentation on the following:
