What is a “Conflict of Interests” - A conflict of
interests can be of two types:
Pecuniary - an interest that a person has in a matter because of a reasonable
likelihood or expectation of appreciable financial gain or loss to the person
or another person with whom the person is associated.
Non-pecuniary – a private or personal interest that a Council
official has that does not amount to a pecuniary interest as defined in the
Code of Conduct for Councillors (eg. A friendship, membership of an
association, society or trade union or involvement or interest in an activity
and may include an interest of a financial nature).
Remoteness – a person does not have a pecuniary interest in a matter
if the interest is so remote or insignificant that it could not reasonably be
regarded as likely to influence any decision the person might make in relation
to a matter or if the interest is of a kind specified in the Code of Conduct
for Councillors.
Who has a Pecuniary Interest? - a person has a pecuniary interest in a
matter if the pecuniary interest is the interest of the person, or another
person with whom the person is associated (see below).
Relatives, Partners - a person is taken to have a pecuniary
interest in a matter if:
·
The
person’s spouse or de facto partner or a relative of the person has a
pecuniary interest in the matter, or
·
The
person, or a nominee, partners or employer of the person, is a member of a
company or other body that has a pecuniary interest in the matter.
N.B. “Relative”, in relation to a person means any of the
following:
(a) the parent,
grandparent, brother, sister, uncle, aunt, nephew, niece, lineal descends or
adopted child of the person or of the person’s spouse;
(b) the spouse
or de facto partners of the person or of a person referred to in paragraph (a)
No Interest in the Matter - however, a person is not taken to have a
pecuniary interest in a matter:
·
If
the person is unaware of the relevant pecuniary interest of the spouse, de
facto partner, relative or company or other body, or
·
Just
because the person is a member of, or is employed by, the Council.
·
Just
because the person is a member of, or a delegate of the Council to, a company
or other body that has a pecuniary interest in the matter provided that the
person has no beneficial interest in any shares of the company or body.
Disclosure and participation in meetings
·
A
Councillor or a member of a Council Committee who has a pecuniary interest in
any matter with which the Council is concerned and who is present at a meeting
of the Council or Committee at which the matter is being considered must
disclose the nature of the interest to the meeting as soon as practicable.
·
The
Councillor or member must not be present at, or in sight of, the meeting of the
Council or Committee:
(a) at
any time during which the matter is being considered or discussed by the
Council or Committee, or
(b) at
any time during which the Council or Committee is voting on any question in
relation to the matter.
No Knowledge - a person does not breach this Clause if the person did
not know and could not reasonably be expected to have known that the matter
under consideration at the meeting was a matter in which he or she had a
pecuniary interest.
Non-pecuniary Interests - Must be disclosed in meetings.
There are a broad range of options available for managing conflicts &
the option chosen will depend on an assessment of the circumstances of the
matter, the nature of the interest and the significance of the issue being
dealt with. Non-pecuniary conflicts of interests must be dealt with in at
least one of the following ways:
·
It
may be appropriate that no action be taken where the potential for conflict is
minimal. However, Councillors should consider providing an explanation of
why they consider a conflict does not exist.
·
Limit
involvement if practical (eg. Participate in discussion but not in decision
making or vice-versa). Care needs to be taken when exercising this
option.
·
Remove
the source of the conflict (eg. Relinquishing or divesting the personal
interest that creates the conflict)
·
Have
no involvement by absenting yourself from and not taking part in any debate or
voting on the issue as of the provisions in the Code of Conduct (particularly
if you have a significant non-pecuniary interest)
Committee members are reminded that they should declare and manage all
conflicts of interest in respect of any matter on this Agenda, in accordance
with the Code of Conduct.
RECORDING OF VOTING ON PLANNING MATTERS
Clause 375A of the Local Government Act
1993 – Recording of voting on planning matters
(1) In this section, planning
decision means a decision made in the exercise of a function of a council
under the Environmental Planning and Assessment Act 1979:
(a) including a decision relating to a development
application, an environmental planning instrument, a development control plan

Rainfall event on the 5 Jan 2023 raised the
Turbidity in plant process between 6 and 7 Jan 2023 (Filter 1 exceeded on one
day and Filter 2 exceeded on both days, see plots below). The finished water
on both days had Turbidity of < 0.75 NTU which is within acceptable
limits, therefore no impact on supply.

Chlorine Residual at Left Bank Reservoir =
0.19mg/L
|
Free Chlorine Residual result during weekly
sample collection and testing on 11 Jan 2023 was found to be 0.19mg/L at Left
Bank Reservoir outlet.
The cause of this issue was the Reservoir
filling had been isolated since 6th Jan 2023. During this time of no fresh
water entering the Reservoir and the high ambient temperatures the chlorine
residual slowly trended lower.
|
The other Reservoir in Mullumbimby had filled
then Left Bank Reservoir inlet valve was returned to normal operations. This
happened on 15 Jan 2023. During this fill 44% of the volume was filled with
fresh filtered chlorinated water from the water treatment plant. After this
Left Bank Reservoir Free Chlorine Residual was sampled as 0.75mg/L on 18 Jan
2023
|
When Reservoirs are isolated. Check Chlorine trends
and if trending downwards dose with sodium hypo to keep level within our set
parameters.

Ammonia Exceedance ‘EPA 1’ of 5.19
mg/L
|
Council was notified of the exceedance by the
lab on 8/07/2022. The exceedance is believed to be due to lower than optimal
Suspended Solids (SS) levels within bioreactor. This SS drop was not
identified by instrumentation.
|
The suspended solids instrumentation was
cleaned and calibrated.
DO setpoint increased
Wasting reduced to increase SS within
Bioreactor which reduces the Ammonia levels.

|
Exceedance was caused by a high rainfall event
which caused high inflows to the plant. Council was notified of the
exceedance by the Lab on 27/5/2022. The exceedance is thought to be due to effluent
being pumped back from the effluent return pond.
|
The dissolved oxygen (DO) setpoints were raised
to help lower the Ammonia will monitor process.

Faecal Coliform Exceedance ‘EPA 1’
of 750 cfu /100 ml
|
Exceedance was caused by a high rainfall event
which caused inflows to the plant of approximately 8 x Average Dry Weather
Flow (ADWF). The UV disinfection (rated at 5 x ADWF) was not able to
cope with the volume and therefore bypass of the UV system occurred.

|
Faecal Coliform Exceedance ‘EPA 1’
of 3750 cfu /100 ml
|
Exceedance was caused by a high rainfall event
over 14th and 15 th February. Hi inflows resulted in bypass of the UV
system.
|
Outflow was retested until FC had dropped to an
acceptable level meeting License). This was achieved by 20/02/2023.

|
Faecal Coliform Exceedance ‘EPA 3’
of 2840 cfu /100 ml
|
On the 23/05/2022 at 1am the wetlands at Ocean
Shores STP started to bypass at the overflow weir due to extreme weather
event with high rainfall and as a result there was a treatment bypass All raw
sewage and stormwater was discharged via primary screening and UV treatment.
The estimated volume of effluent discharged over the four (4) day period was
6.6 ML. No untreated sewage was discharged into the surrounding environment.
As a result, there was a Faecal Coliform exceedance at EPA 1.
|
When flows reduced, a board was placed in the V
notch to allow bypass to be halted. Full treatment re-established.
During and after the incident, operators
monitored and adjusted treatment to correct high faecal coliform, nitrate and
ammonia levels in effluent.
• Council operators carried out
additional sampling at the effluent discharge point (EPA3) and in addition;
monitoring of water quality of the Brunswick River upstream and downstream of
the STP outfall at:
o Upstream of Ocean Shores STP at Federation
bridge Mullumbimby
o Downstream of Ocean Shores STP at Massey
Greene Boat Ramp, Ocean Shore
Bypass was reported to the EPA (Ref: EPA
13060, Reg no. 116.2022.6.1)
|
• Carried out an incident review process
in line with the Pollution Incident Response Management Plan to ensure all
procedures were adhered to and amended if required to prevent future
deviations from procedure. • Perform Inflow and Infiltration
investigation of Ocean Shores sewerage system.
• Review SOP’s associated with wet
weather events for OSSTP

EPA Reportable Events
There was one (1) EPA reportable incident during February
2023.
Reference: EPA
Licence # 13266 - Byron Shire Council self-report, planned power outage
resulting in sewage overflow near Old Brunswick Valley Sewage Treatment Plant,
Brunswick Heads
EPA Ref: 19286
The cause, time and duration of the event
Byron Shire Council (Council) Utilities section received
notification at approximately 9am Thursday 2nd March that a power outage had
occurred at a major sewage pump station (Council reference
‘SPS2000’) near 123 Tweed Street, Brunswick Heads. During this time
there was a planned power outage in the area which affected several other
sewage pump stations within Brunswick Heads as well as the Brunswick Valley
Sewage Treatment Plant. Essential Energy Reference for the power outage is #
69071-R.
Council organised a response within 30 minutes of notification
including:
- Staff contacted
vacuum pump trucks which were onsite at approximately 10:30am.
- Staff contacted
Essential Energy to advise of the issue. Essential Energy did not provide any
assistance to Council.
- Staff organised
for backup generator to be relocated from Ocean Shores STP to SPS2000.
- Staff isolated
all pump stations within Brunswick Heads on SCADA to prevent any additional
flows being pump to SPS2000.
Council’s SCADA monitoring system indicates that
SPS2000 reached high well level at approximately 10:30am. This high well level
had a duration for approximately 1 hour during which time overflows at the pump
station occurred.
By 11:30 am, pump trucks and generators had flows under
control of the site, at which time the clean-up operation begin. Sewage
overflow in proximity to the well was vacuumed up from pump station. Water
tankers were brought in to assist with washing down areas with water being
taken by vacuum trucks.
The type, volume and concentration of every pollutant
discharged as a result of the event
The estimated volume of untreated sewage discharged over the
1-hour period was 50 kL. Due to the proximity to the Simpsons Creek / Brunswick
River, testing was performed in the creek at a location upstream of SPS2000 as
well as downstream of SPS2000. Testing was performed in the open drain / swale
immediately adjacent to SPS2000. Location overview for testing sites is in
Appendix A.
During the time of the break, it was dry weather, it was
approaching low tide with the tide was running out. Untreated sewage was mainly
localised around the SPS2000 site as well as open stormwater drain shown.
Action taken by the licensee in relation to the event,
including any follow-up contact with any complainants.
• During the
incident, council staff monitored levels within the pump station and responded
to issues within a timely manner e.g., organisation of pump trucks and
generator
• Localised
overflow was removed (using vacuum excavation) and then the site was washed
down with tankered water with further vacuum excavation. Disinfectant was
applied to affected areas.
• Council
staff performed environmental sampling at two locations along Simpsons Creek
(one upstream and another downstream) as well as at the stormwater system
adjacent to the main break on 2nd March 2023.
(a) Details of any measure taken or
proposed to be taken to prevent or mitigate against a recurrence of such an
event;
• Review
internal planned outage process and update accordingly.
• Review
storage capacity at SPS2000 and determine whether emergency storage is a viable
option for this site.

Byron Wetlands Water Quality
The data below shows the assimilative and
polishing capacity of Byron Wetlands for the December 2022 to February 2023
period.
From: WaterOutlook > Reports > Special > MONTHLY
UTILITIES REPORTS > UTILITIES REPORT - Wetlands Performance
The assimilative and polishing capacity is
demonstrated by the nutrient reduction trend between EPA1 and EPA 4 for
nitrogen and phosphorus concentrations as follows:
• Total
Phosphorus - an average increase of 10% to 35% is seen between EPA1 and
EPA4, this increase is not in line with the reduction seen in the literature of
around 40-60%. It is noted however, that this result is a factor of very low
Phosphorus levels entering the Wetland, leaving very little scope for
improvement. In addition, small variations in concentrations are
amplified due to the way the target is calculated. Discharge
concentrations of 0.11-0.14 mg/L are still significantly below the EPA limit
for discharge from the STP of 1.0 mg/L.
• Total
Nitrogen - an average reduction of between 66% and 77% is seen between EPA1
and EPA4. This is significantly better than that seen in the literature
of around 40-55%
Byron Wetlands (BBIWMR) Water Quantity
The below graphs are based on monitoring data
and water-balance modelling for the BBIWMR site.
Key observations:
- The
24ha site irrigation system remains inoperative and has not been irrigated
during the reporting period. Substantial additional effluent reuse can be
obtained by reactivating this system. Investigations are undergoing to define
best way to reactivate the system.
- Rainfall
is the main driver for high flows coming out of the system, as well as
groundwater levels. See sharp spikes in both the 1st and 3rd graphs, which
coincide with high rainfall events.
Note: Groundwater level data is only
available until 1/11/2022. Improvements to groundwater monitoring infrastructure
are required to enhance data availability. 
Wetlands Operation
Monthly inspections and checklists
have been completed by AWC in the December 2022 to February 2023 period. Drain
clearing was completed and clearing around the wetland inlets was also
completed.
Shane Austin has completed the
clearing at inlets and clear access is now possible to the majority of the
wetland operational area. Another maintenance run with clearing at inlets and
minor trimming has commenced. Water levels were slightly lower through
December and January due to reduced rainfall, high evaporation and drain
clearing. Water levels were higher through February due to rainfall.
Investigations into the acidic water and sulphurous smell within the lower
section of Cell D are indicative of ASS, sampling will be undertaken to confirm
this. Cell D and E are currently offline.
The DPI research team has released
weevils into a number of locations and completed monitoring including Drone
survey in December and February. Weevil numbers were high in Cell H and as a
result there has been a significant reduction in the Salvinia cover.
Bird buddies January monitoring
identified both Lathams Snipe and a large number of black ducks likely to be
increasing due to the improved conditions in Cell H.
Reduced Salvinia cover Cell H
Recycled Water Management
Strategy
Update on project
progress:
As per resolution from
December 2022 ET meeting, investigations are being carried out to upgrade urban
effluent reuse treatment and management systems. A follow-up report will be
presented to ET in March/April 2023.
Improvements to systems,
plans and procedures for effluent management
Recycled water user
agreements register: An Authority register is being developed to improve record
keeping and management actions related to Recycled water user agreements. A
similar approach will be used to keep track of recycled water refill station
users.
Recycled water use
agreement with Open Spaces: This will be a priority in the first quarter of
2023.
Urban reuse data, monitoring
and compliance: Urban reuse monitoring data is being centralised in water
outlook, and benchmarked against the Draft Recycled Water Management System
(2016 – CM9 # E2020/53024). While this document has not received approval
from DPE, it is currently the best reference to guide best practice. Monitoring
framework and objectives will undergo changes as the system is upgraded to
satisfy dual reticulation requirements.
Main Arm Recycled Water
Scheme
MARWS has not been in use
since April 2022 as there was no demand due to high rain fall/flooding. In
January 2023 the Johnson Farm (only user in this recycled water scheme),
requested water to be supplied again. However, several issues have been found
with the supply and treatment processes at the old Mullumbimby STP site (pump,
chlorination and aerators). Repairs are being planned by the Operations team.
Estimated completion time is unclear.

PLANNED & REACTIVE
ASSET MAINTENANCE
Planned Maintenance
Overall planned maintenance
stands at 91% of tasks completed by due date in February 2023. This is
significantly up from 48% in January 2023. However, the long-term average
compliance for the last twelve months is just below target at 79% (target of
80%).
This significant increase in
compliance is primarily due to mains flushing tasks being completed across the
Shire over the last month.
It is noted that;
a. the
only team below target compliance is now Sewer Operations. This team has
significant increased compliance since last month from 62% in January to 72%
currently. This demonstrates the team’s recovery from staff
shortages is underway.

Maintenance
The reactive
maintenance tasks have been below average in January (44 tasks completed

Task Closeout
There are now 210 open and
aged reactive maintenance tasks, down from 427 in January. This reduction
is due to a concerted effort to close out aged CRMs as we move across to the
Assetic maintenance system.
Utilities are in the process
of moving to new maintenance management software (Assetic). Brightly
Maintenance Management software. The Water Reticulation team have now
been trained in the software with the ‘Go Live’ for this team
scheduled for 2 March 2023. The software will be rolled out to all teams over
the coming months.

UTILITIES SUSTAINABILITY
Solar PV Arrays Performance
Byron Shire Council currently
has 600kW of solar PV panels installed across 15 sites. Of this 350kW is
installed across the West Byron, Brunswick Valley and Bangalow STP sites. The
Sustainability Officer Utilities (SOU) is responsible for monitoring and
reporting on the performance of all of council’s solar PV arrays as well
as identifying issues and arranging repairs when necessary. Asset owners are
responsible for paying for repairs and maintenance of the solar assets for
which they are responsible.
When the SOU assumed this responsibility most of the
sites had issues with either the hardware on site and/or the configuration of
online monitoring portals. As can be seen in the screenshot above all of
council’s sites are now operational and configured properly. This has
been achieved through weekly monitoring and engaging with Asset Owners,
Contractors, and online monitoring portal technicians.
An annual report is prepared by the SOU to communicate
to ET solar system performance and technical findings. The key finding other
than the importance of regular monitoring and maintenance is that solar
installed behind the meter to reduce power import from the grid provides an ROI
several times that of power sold back into the grid under feed in tariff
arrangements.
Quarterly Utilities Assets Energy Performance
Monitoring
This table and Key Points is updated
quarterly/annually. The tables below display the Utilities sites that have had
the largest increases in electricity usage from Q2 2021/22 to Q2 2022/23. It
also applies the standard energy efficiency metric of kWh/kL which demonstrates
these sites power consumption per units of influent flow. This metric allows
sites to be identified for investigation and optimisation through CRM requests
to the Principal Engineer System Planning and the Operations Engineer. Once CRM
requests are made sites are monitored and will remain as unresolved items in
the IS monthly report until the identified anomalies have been rectified.

Key Points
• SPS3001
and SPS3002 again showed significant increases in energy usage but Inflow data
was still unavailable so a performance metric could not be applied. The missing
data will require further investigation.
• Depot
Training Room and SPS3023 saw a 61% increase. This is most likely due to more
use of the Training Room. The recent installation of VFD’s to SPS3023 has
significantly improve the power factor of this site and consequently reduced
the kVA demand charge on the monthly electricity bills for this site.
• SPS3004
experienced a 111% increase in energy usage but while derived flow was
unavailable in Water Outlook pump runtimes had doubled correlating with the
increase in energy usdage.
• SPS4000
experienced a 70% increase in energy usage and 300% increase in kWh/kL. This
site will be investigated further.
Follow Up
• SPS5003
pump 1 has been recommissioned after servicing. Energy performance metrics will
be applied to this site when the Feb 23 electricity bill/meter read is
available.
• SPS5009
is continuing to demonstrate improved energy efficie3ncy since the servicing
and recommissioning of the jockey pump.
• SPS4000
is showing increasingly inefficient energy efficiency and needs to be
investigated.
• SPS4004
experienced a 53% decrease in energy usage due to a halving of pump runtime.
CAPITAL WORKS
Byron Shire Bioenergy Facility Project
Council’s independent solicitors HWL Ebsworth
advised finally, upon its further review, that its opinion is that the
Bioenergy Facility project must apply for assessment by the NSW Office of Local
Government for a Public Private Partnership, in the event Council wishes to
accept private equity financing for the D&C and O&M of the facility.
Further to ET recommendations, Utilities shall report
on possible commercial delivery and contracting alternatives for the project,
again to the Executive Team in March 2023 and then to Councillors in April
2023.
Two additional Commonwealth grant streams are expected
in 2023 and might be potential funding sources for the BEF project; they shall
be reviewed and considered when more detailed information is available. The
grants are from the Department of Infrastructure, Transport, Regional
Development, Communications and the Arts: the new “Regional Precincts and
Partnerships Program”; and the “Growing Regions Program” (to
replace the now-cancelled BBRF Round 6 Grant Fund). These funds could be put to
offsetting the costs of a PPP delivery model.
SPS Renewals for Byron, Mullum, Ocean Shores &
Bangalow
The sewer pump station renewals programmed in 2022/23
includes 24 pump stations in total. The scope of work is summarised in the IS
Monthly Status Report – February 2023. The refurbishment of the
receival MH at SPS 3001 was added to the list in August to address urgent
repairs and has been completed. The following works have been completed in the lead
up to the replacement works:
• Hydraulics
calculations and pump selections made.
• Pumps
have been ordered.
• Switchboards
have been built and delivered
Condition Assessments – FY21/22
The condition assessment of gravity sewer mains and
maintenance holes was awarded to Willow and Sparrow (Maintenance holes) and
Subsurface Mapping Solutions (Mains). The Maintenance hole condition
assessments are complete apart from some with access difficulties. The CCTV
mains contract was awarded to Subsurface Mapping Solutions and was completed in
June 2022. The sewer catchments that fall within this scope include, 2002,
3001, 3003, and 3006.The indicative budgetary limit of $300,000 has been
exceeded as this is a combination of costs for both CCTV assessments and MH
visual assessments, largely due to the use of the heavy cleaning provisional
item due to the large number of blocked mains in these catchments. Reporting is
currently underway to establish necessary renewals scope from these catchments.
The reports are expected to be finalised before the end of March 2023.
Gravity Sewer Rectification – FY21/22
The
gravity sewer rectification scope involves the rectification of over 300 assets
throughout previously assessed catchments, 3002, 4001, and 5012. The works have
been awarded to Interflow who commenced in March 2022 but have been heavily
delayed due to the inclement weather. It is expected that the contract will
extend to April 2023 due to delays with flood and rain affected areas.
Interflow will keep BSC updated on the impact to the holistic program schedule.

• Over
the summer period, a small leak at Yamble Reservoir was identified, likely due
to the poor concrete quality and changes to the reservoir over the works period
(i.e. a long period of having the tank empty / dry, then filling of the tank
– the concrete shrinks and swells and minor movements can cause cracking,
especially with an old tank of average to poor quality). The leak was injected
with a potable-water friendly product in January and the leak has since
stopped. Ongoing monitoring of the crack injection location is being undertaken
weekly and will continue for the next few months.
