ACKNOWLEDGMENTS This work was completed under ADOT Contract T08-49-AK001, Task Assignment TPD 21-08, PO No. PG-TD0115. Beverly Chenausky at ADOT served as the project manager and provided invaluable help and technical advice during the study. Dustin Berry at Bison Construction Company, the ADOT contractor responsible for completing the road work, provided STI with access to construction equipment, assisted STI with GPS unit installation, and facilitated the transfer of various data to STI either directly or via ADOT staff. Bill Harmon and Tony Hanna with the ADOT Safford District Office assisted with data collection (e.g., daily fuel use) and kept STI apprised of construction schedules and local conditions that might have an impact on monitored activity and air quality. Joonwon Joo at ADOT helped provide construction diaries. Jackie Watkins of Benson Construction provided STI with site-specific information. Chris Moore of Parsons Brinckerhoff provided STI with construction planning documents that aided in the selection of monitoring locations. Staff from Sulfur Springs Valley Electric Cooperative, the Yaqui Electric Company, and Arizona Land Specialists assisted in providing electrical power to the monitoring trailers. Karole George, a resident in the area near the construction work, allowed STI to place monitoring trailers on his property during the course of the study. Joey Landreneau of STI assisted with the installation of the air monitoring equipment. Alison Ray of STI performed audits of the air monitoring equipment, assisted with the removal of the air monitoring equipment, and performed some of the data validation. Jon Kaiser, Jeff Prouty, Siana Alcorn, and Eric Gray assisted with the setup of the air monitoring database and website. Terry Graham, sometimes assisted by Kathy Graham, performed routine checks of the air monitoring equipment, provided local technical support for the study, and assisted with the removal of the air monitoring equipment. Jennifer DeWinter, Theresa O’Brien, and Joshua Shiffrin performed data validation of portions of the air monitoring data. Dr. H. Christopher Frey, professor in the Department of Civil, Construction, and Environmental Engineering at North Carolina State University, Dr. Deb Niemeier of the University of California, Davis, and Mr. Guido G. Schattanek of Parsons Brinckerhoff each graciously assisted the study team in answering technical questions and obtaining related technical information. Finally, appreciation goes to the STI support staff who assisted with the preparation and delivery of our project work products and generally supported field operations: Chelsea Jennings, Dennis O’Reilly, Jana Schwartz, Mary Jo Teplitz, and Mary Anne Slocum. iii TABLE OF CONTENTS Section Page LIST OF FIGURES ..................................................................................................................... viii LIST OF TABLES....................................................................................................................... xiii EXECUTIVE SUMMARY .......................................................................................................ES-1 1.
