Re: Request for 6-month extension of deadline
Dear Ms. Holman,
I would like to request a 6-month extension of the deadline for our project, ‘Development of a
Total Organic Fluorine (TOF) Method for the Analysis of Process Wastewater Streams and Air
from Fayetteville Works (NC)’, to December 31, 2021. This request is due to the impact of the
Covid pandemic, including the 2nd wave, which has limited our capacity in the laboratory. We
need this time for the successful completion of our TOF method. We are hoping that we can
deliver the final TOF method before December 31, 2021 if at all possible.

Sincerely,

Susan D. Richardson, Ph.D.
