Correction to 5/25/21 Statement: On 5/25/21 Daniel Meyer stated PCCD will attempt to open the slide
gate prior to the Notice to Proceed if it is operational. However, PCCD has decided NOT to open theslide gate unless needed to fulfill its normal maintenance obligations to NRCS as the Primary Local

under orders of the Texas Commission on Environmental Quality with respect to Dam Safety under Texas
Laws. The Contractor will be responsible for all operations necessary as specified in Construction
Specification 11, Removal of Water. As a reminder, no work may be performed at the construction site
until receipt of a Notice to Proceed from the Contracting Officer.
