This report presents methodologies that use considerably less than a full year of data for estimating the two critical annual statistics of the carbon monoxide levels at a proposed highway site--the annual second maximum 8-hour average and the annual second maximum 1-hour average. Therefore, it is of substantial interest to highway professionals responsible for preparation of environmental impact statements. Among such professionals are engineers, meteorologists, and statisticians. They will find step-by-step procedures for applying the methodologies, for various conditions of data availability, to determine magnitudes of CO concentrations and their confidence limits. An example application is provided. /Author/
