Title: Highway Vehicle Activity and Emissions (Renewal).

Abstract: EPA is initiating a data collection to target two research objectives related to emissions inventory estimation for highway vehicles. The first is to examine differences in vehicle speed among differing vehicle types and road types. The second is to measure emission rates for samples of vehicles stratified by year of manufacture and regulatory class. Data to be collected include “in-use” or “real world” vehicle speed and 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 highway vehicles. This study will combine rapid in-use measurement capability with statistical survey design to contribute to the development of usage and emission rates for the EPA Motor Vehicle Emissions Simulator (MOVES) model. Response to the survey is voluntary.

The target population is highway vehicles registered in the study area. EPA shall recruit vehicles from State registration databases and from regional or state Inspection and Maintenance Programs (I/M).

Emissions and usage will be measured using portable on-board electronic instrumentation. Emissions instrumentation will measure carbon dioxide (CO2) and several air pollutants with one second resolution during normal operation over a period of one to three days. Air pollutants to be measured include, but are not limited to, carbon monoxide (CO), total hydrocarbons (THC), and oxides of nitrogen (NOX). The usage instrument will measure with one second resolution engine on/off, vehicle speed, and vehicle location over a period of approximately one month.

Data will be collected during normal operation. Following quality-assurance and analysis, the data will be stored in OTAQ's Mobile Source Observation Database. The information collection will involve 1,285 respondents, requiring 1,327 hours at a total cost to those respondents of $35,672. For the agency, the collection will require 26,327 hours at a total cost to the agency of $1,532,629.

An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless 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 1.0 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: Owners of highway vehicles.

Estimated Number of Respondents: 1,285.

Frequency of Response: One time.

Estimated Total Annual Hour Burden: 1,327.

Estimated Total Annual Cost: $35,672, which includes $0 annualized capital/startup costs, $0 annual O&M costs, and $35,672 annual labor costs.

Changes in the Estimates: There is a decrease of 322 hours in the total estimated burden currently identified in the OMB Inventory of Approved ICR Burdens. This decrease is due to installing instruments at a vehicle's “depot location” versus having owners commute to a central location. The total costs to the respondent will decline in kind based on the total hours.
