In response to recommendations from
the National Research Council of the National Academy of Sciences,
EPA is continuing a systematic data collection designed to improve
the methods and tools used by the Agency to estimate emissions from
nonroad equipment. Data to be collected include populations, usage
rates (activity) and "in-use" or "real-world" emission rates. The
collection is a survey, to be conducted by the Office of
Transportation and Air Quality (OTAQ) in the Office of Air and
Radiation (OAR). Development of rapid in-use instrumentation
promises to substantially reduce the cost of emissions measurement
for nonroad equipment. This study will combine rapid in-use
measurement capability with statistical survey design to improve
the representation of nonroad engine populations. The goal is to
continue a pilot survey designed to develop methods and protocols
needed to collect data on populations, activity and in-use
emissions of diesel nonroad equipment. Response to the survey is
voluntary. The target population includes nonroad equipment used by
commercial establishments in the construction and manufacturing
sectors. The study area for this collection will include areas in
EPA Regions 5 and 7. To estimate the prevalence of equipment
ownership in the target sectors, 1,500 establishments will be
requested to respond to brief interviews regarding their equipment
ownership and use. Emissions and usage will be measured using
portable on-board electronic instrumentation. Emissions
instrumentation will measure carbon dioxide (CO2) and several air
pollutants on an instantaneous basis during normal operation over a
period of one to three days. Air pollutants to be measured include
carbon monoxide (CO), total hydrocarbons (THC), oxides of nitrogen
(NOx) and particulate matter (PM).
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.
