noise monitoring locations as well as
compliance checks in accordance with the MOAs and associated
attachments, exhibits, traffic closure
notifications, and traffic management plans. At the conclusion
of each work shift, daily monitoring reports
were prepared by the ICM. Any violations for that date were also

construction activities. Daily monitoring reports
and photographs of construction activities are provided as
Attachment A. Daily noise monitoring data are
