This survey is approved as a limited pilot program, not to exceed the scope described in the supporting statement and burden estimates. However, the researcher may engage in additional contacts to convert nonresponses and investigate effective conversion techniques. In future submissions, the agency should separate the component information collections of this survey into separate ICs for the screening survey and for the data collection.

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. The total sample size for instrumented measurement is 100 equipment pieces, with 50 pieces targeted for emissions and usage measurement, respectively.
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). The usage instrument will measure engine on/off over a period of approximately three months.
Data will be collected during normal operation at the respondents'facilities or work sites. Following quality-assurance and analysis, the data will be stored in OTAQ's Mobile Source Observation Database. The information collection will involve 517 respondents per year, requiring 99 hours per year to complete at an annual total cost to those respondents of $6,716. For the agency, the collection will require 4,455 hours per year at an annual total cost to the agency of $322,415.
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.
