This ICR has
been withdrawn at the request of EPA. The June 2000 approval of the
existing collection for light-duty vehicles remains in effect until
June 2003. EPA intends to submit two ICRs that would request
approval to conduct pilot studies of non-road and heavy-duty
highway engine usage. Following successful completion of the pilot
studies, EPA may submit separate ICRs to OMB to seek approval for
full-scale surveys. Because EPA has already published two Federal
Register notices requesting public comment on these studies, in the
case of the ICRs seeking approval for the two pilot studies, OMB
will waive the requirement that EPA publish a new Federal Register
notice at least sixty days before resubmission to OMB as otherwise
required by 5 CFR 1320.8(d). OMB believes that collection of
reliable data about emissions from these types of equipment in use
is an important and worthwhile objective, and hopes that
appropriate pilot studies can be developed and initiated
expeditiously. To this end, OMB is available to work with EPA
before submission of the pilot study ICRs to assure that the
surveys meet high standards of reliability and statistical quality
without imposing unnecessary burden on respondents. Successful
pilot studies will address the issues described below. EPA should
address these issues before submitting ICRs for the pilot studies
to OMB for approval. >>>Nonroad Pilot Study EPA needs to
conduct pilot studies to examine the feasibility of collecting data
on the populations of nonroad vehicles, the activity of nonroad
equipment, and the average power output and emissions rates for
nonroad vehicles. As part of this effort, methodological research
needs to be conducted to determine the appropriate methods for
gathering this kind of data. More specifically, pilot
investigations need to focus on: --development of appropriate
sample frame(s) for establishments that have nonroad vehicles. In
developing the frames, the agency should keep in mind the
likelihood of potential coverage errors and the precision of the
estimates that it wants to obtain. --evaluation of assumptions
about the likelihood of establishments owning nonroad equipment
--evaluation of all questionnaires using appropriate cognitive
methodology on potential respondents. --design of a separate frame
and appropriate questionnaire for household respondents
--implementation and execution of a screening survey with
acceptable response rates The goal of these pilot tests and
research investigations is NOT to provide estimates for any
population parameters or models, but is to evaluate the feasibility
of the methods and procedures that can be used to obtain this kind
of information. Therefore, the data gathered as part of these pilot
studies will not be appropriate for estimating central tendency,
relations among the characteristics of the equipment and emissions,
or for inclusion into NONROAD models. >>>Mobile Pilot
Study EPA needs to conduct pilot studies to examine the feasibility
of collecting data on the emissions rates for on-highway heavy-duty
vehicles. As part of this effort, methodological research needs to
be conducted to determine the appropriate methods for gathering
this kind of data. More specifically, pilot investigations need to
focus on: --development of appropriate sample frame(s). In
developing the frames, the agency should keep in mind the
likelihood of potential coverage errors and the precision of the
estimates that it wants to obtain. --design of a separate frame and
appropriate questionnaire for household respondents. The goal of
these pilot tests and research investigations is NOT to provide
estimates for any population parameters or models, but is to
evaluate the feasibility of the methods and procedures that can be
used to obtain this kind of information. The data gathered as part
of these pilot studies will not be appropriate for estimating
central tendency, relations among the characteristics of the
equipment and emissions, or for inclusion into MOBILE models.

The goal of this collection effort is
to develop sound, defensible mobile source inventories that
characterize the operation of on-highway vehicles and nonroad
equipment under real world conditions. Information collected
provides a basis for developing State Implementation Plans,
Reasonable Further Progress reports, and attainment status
assessments for the National Ambient Air Quality Standards. The
respondents include the general public that own motor vehicles and
owners/operators of nonroad equipment and heavy-duty on-highway
vehicles.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).
The following is a summary of the topics, regarding
the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a
benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control
number;
If you are unable to certify compliance with any of
these provisions, identify the item by leaving the box unchecked
and explain the reason in the Supporting Statement.
