Outfall 005 is new and serves as a bypass from a new underground detention structure installed to
help reduce polluted discharges from the site. It had not been cleaned out since construction, but
a full cleanout and inspection was completed on May 21, 2021. Please note that regular
inspection and maintenance will be done going forward. Additional response measures include
enhanced in person site -specific training for staff.
Please feel free to contact me at [phone] if _you would like to discuss this issue further.
Sincerely,
