SUBJECT Oil/Water Separator Tees Not Installed Per Plan, Bank of Washington, SW Comer of
5th Avenue South, Edmonds, JRR #06-67A
REF: Permit #: 2006-0558
Dear Ms. McConnell:
JRR Engineering, Inc, (JRR) understands the inlet and outlet tees were not installed in the oillwater
separator per the approved plans for the above subject project. Since the baffles were installed and
only 9.4 feet was needed for length of flow path (over 12 feet should exist within the detention vault)
it is our opinion the control tee within the vault Is adequate And the tees witbin the separator may be
omitted.
Please advise if you have any questions or concerns regarding this matter.
Sincerely,
JRR Engineering, Inc.
