Title: Mobile Source Emission Factors: Populations, Usage and Emissions of Diesel Nonroad Equipment in EPA Region 7 (Survey)

Abstract: In response to recommendations from the National Research Council of the National Academy of Sciences, EPA is initiating 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 to conduct 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 Mining, Construction, Manufacturing and Agricultural sectors. The study area for this collection will be EPA Region 7. To estimate the prevalence of equipment ownership in the target sectors, 1,540 establishments will be requested to respond to brief interviews regarding their equipment ownership and use. The total sample size for instrumented measurement is 360 equipment pieces, with 150 and 210 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 1,900 respondents at a cost of $91,900.

The legislative basis for gathering this data is section 103(a)(1)(2)(3) of the Clean Air Act, which requires the Administrator to “conduct * * * research, investigations, experiments, demonstrations, surveys, and studies relating to the causes, effects, extent, prevention, and control of air pollution” and “conduct investigations and research and make surveys concerning any specific problem of air pollution in cooperation with any air pollution control agency * * *.”

An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information Start Printed Page 12152unless it displays a currently valid OMB control number. The OMB control numbers for EPA's regulations in 40 CFR are listed in 40 CFR part 9 and are identified on the form and/or instrument, if applicable.

Burden Statement: The annual public reporting and recordkeeping burden for this collection of information is estimated to average 0.42 to 0.75 hours per response. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information.

Respondents/Affected Entities: Commercial establishments in the Mining, Construction, Manufacturing and Agricultural Sectors (NAICS 21, 23, 31-33, and 111, respectively).

Estimated Number of Respondents: 1,900.

Frequency of Response: one-time event.

Estimated Total Annual Hour Burden: 1,060.

Estimated Total Annual Cost: $91,900, includes $0 annualized capital or O&M costs.
