Subject: Installation of Emergency Gas Scrubbers
Dear Mr. Weaver:
This letter is to reiterate and clarify our conversation earlier today. The City of Burlington will be
installing emergency gas scrubbers to contain and mitigate any releases of chlorine or sulfur dioxide gases
at the South Burlington Wastewater Treatment Plant (WWTP) and East Burlington WW1P. The
scrubbers will be connected to the existing chlorine/sulfur dioxide buildings through a duct leading to the
scrubber.
This project does not affect the treatment process in any way, and is being done solely as a safety
measure. Based on our conversation, it was detcnnined that an Authorization to Construct permit will not
be required for installation of the scrubbers.
Sincerely,
ALLEY, WILLIAMS, CARMEN & KING, INC.
