(3) Introductions- Larijai Francis- City Project Manager for Water Resources
(4) Discussed and possible action regarding City Project E16265 (Corpus
Christi Aquifer Storage and Recovery Feasibility Project) Kick-off Meeting.
Project Manager Larijai Francis presented Kristy Shaw and Troy St. Tour with
HDR Engineering to the Board Members. HDR suggested three areas with ASR
potential.
• O.N. Stevens WTP
Airport towards Ship Channel
Greenwood WWTP
A successful ASR project would be one that provides needed water during times
when demand exceeds supply at a lesser cost than other options. Success should not

be tied to recovery efficiencies. Mark V. V. suggested replacing the Greenwood WWTP
term to the future North WWTP.
Discussion was had outlining the primary goals and objectives for the ASR pilot
program. The City and District would like to consider ASR to meet seasonal peak
demands as well as storage of excess water when available to use for back-up supply
during drought intervals.
A drilling program preference was agreed upon which would help maintain
flexibility in the drilling program and avoid costly expenditures and collection of detailed
information at sites that may be unsuitable for ASR. The City and District prefer to
conduct preliminary tests with smaller boreholes to collect lithology and geophysical
data, and if conditions are favorable, proceeding forward with collecting samples for
laboratory analysis and aquifer testing.
In terms of, the RFI/RFQ process to procure a driller for the ASR program, the
City will issue the standard Request for Competitively Sealed Bids to procure the driller.
The City and District is interested in seeking water supplies up to 20,000 —
30,000 ac-fUyr (or 18 to 26 mgd). Providing geology is favorable, the City would like to
consider diverting water from reservoir system storage for pre-treatment and ASR
storage rather than subjecting it ti evaporative losses.
Summer peaking and and/or long term for water banking. Both types of
operations are possible and will need to be considered as part of the study.
The anticipated end use of water stored in the ASR system could be used by
local industries or potable water customers, keeping in mind that ASR stored water may
need additional treatment after recovery to treat to potable standards for drinking water
distribution.
The City and District would like the study to consider treated effluent from a North
WWTP (potential) and/or water from the potable, distribution system as the source
water for ASR. Water quality data from Greenwood WWTP will serve as a proxy for
treated effluent.
Kristi informed the District that her consultation with TCEQ staff reported no
TCEQ permission or authorization is required for an exploratory well program if water is
not being injected into the aquifer. HDR will set up a meeting with TCEQ staff to
determine how rules will be interpreted, and if it requires that a City have a controlling
interest in all land above ASR storage zone, or just where wells exist.
HDR consultant described the five major work tasks associated with the study:
program formulation, exploratory test drilling program, geochemical analysis/modeling,
field scale groundwater model, ASR operating procedures, and meetings/reports. Key
factors affecting the successful implementation of an ASR project include regulatory,
infrastructure, and hydrogeologic compatibilities. This project focuses on the
hydrogeologic component, but will also consider regulatory issues associated with water
quality standards. HDR will seek to identify ASR opportunities that are compatible with
new infrastructure or other ongoing projects.

An updated schedule was presented in response to contracting set-backs and
kick-off meeting scheduling. A draft report is due to the TWDB by March 29, 2019; and
final report is due by July 29, 2019. Interim technical memorandums will be provided to
City Staff and the District upon completion of each of the major tasks, and prior to status
update meetings with the TWDB. The schedule estimates 45-60 days to review drillers
bid proposals, with notice to proceed by the City/District by June 13, 2017.
(5) Public Comment: There was no public comment.
(6) Date for next meeting and identify items to be placed on Agenda: The next
meeting will be February 2, at 10:00 p.m.

member Tom Tagliabue and seconded by Board member Fred Segundo.
