of the landfill base grades from NHDES is expected 30 days after submission of all required
groundwater data. NHDES has specified that no work associated with liner system installation,
including the 6-inch Screened Till layer, can begin until they have granted approval. All other
work not associated with the liner system installation can commence after the contract has been
executed.”

“Notice to Proceed”, is anticipated to be issued in the April of 2019. Completion time for the
project will be calculated, in calendar days, from the date of the issuance of the “Notice to
Proceed”, as follows:

150 calendar days for substantial completion
