The meeting, which was held for the purpose of discussing the report from consultants on the
TMDL/Wastewater Study and Recommendations,was called to order at 5:00 p.m. by Mayor
Meserve. He then explained the process for discussion at Workshops.
Gordon Grimes and John Collins representing HDR Consultants of the TMDL Compliance Study
gave a presentation,which is attached and made part of this official record as Attachment A.
Subjects included how to meet the new(TMDL) standards limiting the discharge of nitrogen into
the St. Johns River from City wastewater plants and the storm water system. The possibility of
treating the wastewater and distributing it to several possible customers for irrigation(called reuse)
was one option. Possible upgrades of both of the city's wastewater plants were considered. The
elimination of the Buccaneer wastewater treatment plant(WWTP#2)either through sending the
wastewater to JEA for treatment or re-piping to the city's main wastewater plant(WWTP#1)was
also considered. The recommendations were to upgrade WWTP#1 to meet the new wastewater
standards,eliminate WWTP #2 by re-piping the wastewater to WWTP #1,and to plan for an
expansion in capacity from 3.0 millions of gallons per day(MGD)to 5.0 MGD for WWTP#1. The
timetable and phasing for the expansion would be further considered after the results are available
of an ongoing study about the possibility of taking wastewater from the City of Neptune Beach for
treatment at Atlantic Beach's WWTP#1. The results of that work are expected in late winter or
spring of 2009.
After review and discussion, it was the consensus of the commission to support the
recommendations of the consultants and request that an amendment to the engineering contract
with HDR be prepared for commission approval at a regular meeting that would continue their
work by designing the upgrade of WWTP#1,eliminate WWTP#2 and make preliminary plans to
expand WWTP#1 to a capacity of 5.0 MGD.
There being no further discussion by the City Commission, the Mayor declared the meeting
adjourned at 6:53 p.m.
