When Clarence Valley Council tries to ignore the elephant in the room and local media with the best of intentions doesn't even see that enormous pachyderm


For reasons best known to itself, Clarence Valley Council administration has not publicly dotted the "i"s and crossed the "t"s for elected councillors and the Clarence Valley resident population when it comes to root causes of increased water turbidity and poor quality drinking water.


It's all about dirt. The deep soils and topsoils which cover and strengthen the rocks which hold Clarence River Basin mountains, hills and slopes in place; soils which are building blocks for both vegetation & biodiversity growth; soils which allow arable farming on valley floors big and small - including on the identified Clarence River floodplain.


The connection between clear-felled land, disturbed soils caused by mining, state-owned & private forestry, land laid bare by largescale wildfires, sloping land eroded by rain bombs, river banks scoured by record flooding, waterways thick with suspended soil particles and, a decline in water quality, is there for all to see. 


As is the poor stewardship of the NSW Government - which is supposed to ensure healthy waterways - but whose actions in allowing inappropriate levels of native vegetation removal, poorly monitoring mining exploration activity and its own continuous native timber forestry in sensitive catchments & sub-catchments is contributing to turbidity issues in north-east New South Wales.


It appear that absolutely no-one in the Perrottet Coalition Government is looking to address the root cause of water turbidity and erratic urban water quality. 


There appears to be a political blindness in 2023 to the following:


(i) the 2019-20 megafires started a process of exposing soils over wide areas of what had been closed and open forests in the Northern Rivers region;


 (ii) the further clearing of some of those fire grounds for retrievable native timber exacerbated this process; 


(iii) in 2022-23 the sensitivity and environmental risk associated with these forests is recognised as a continuing issue by the NSW Environmental Protection Agency - especially in areas where commercial native timber forestry is still occurring;


(iv) the 2022 extreme flooding increased the rate at which destabilised and/or degraded soils, particularly the exposed dispersive soils which create high levels of turbidity, made their way into streams, creeks, rivers and major waterways; and


(v) riverine landscapes do not have an infinite ability to withstand population pressure coupled with an increase in the frequency of natural or climate-induced disasters. The resilience Clarence River Basin waterways have demonstrated in the past does not guarantee their future capacity to experience recurrent disturbances while retaining essential function, structures and feedbacks.


A filtration plant may be advisable for urban water supplies, but it won't keep Clarence Valley waterways healthy, alive with biodiverse aquatic ecosystems and productive.


Ecotourism, water-based activity tourism and freshwater recreational fishing tourism, as well as the lucrative local wild-caught prawn industry, depend on healthy rivers. Rivers that are not just healthy but that can be seen to be healthy.

Clarence Valley Independent, 1 March 2023:


Future filtration for Valley water


Filtration of the Clarence Valley’s drinking water supply is again back on the agenda following this months Level Four severe water restrictions which lasted 11 days.


The Rushforth Road Water Treatment Plant RRWTP masterplan, which aims to replace the existing reservoir without impacting future construction of a filtration plant, is on the agenda at the February 28 Clarence Valley Council CVC meeting.


Prepared for council by consultant Beca H2O, the masterplan includes the replacement of the existing 32 megalitre reservoir, which is included in CVC’s 2022/2023 Operational Plan, and for future construction of filtration.


It is recommended that Council progress the Masterplan by commencing the planning approval process for a future filtration plant at Rushforth Road Water Treatment Plant,” council papers state.


Council staff recommend councillors note the masterplan and commence the planning approval process for future construction of a filtration plant by calling open tenders to undertake an Environmental Impact Statement.


CVC first adopted a Drinking Water Management System DWMS at its August 19, 2014 meeting and an updated DWMS was adopted at the May 2020 meeting.


Up until the 1990s, drinking water was extracted regardless of turbidity, then in the early 1990s selective extraction was introduced to improve water quality when turbidity was below 10 Nephelometric Turbidity Units (NTU).


Councils 2014 DWMS saw the turbidity level drop to 5 NTU, then the May 2020 DWMS further dropped the turbidity level to 3.5 NTU.


Currently, CVC water supplies are disinfected at Rushforth Road “by chloramination (adding ammonia to chlorine) as this provides the most stable disinfectant in lengthy pipeline systems because chloramines decay at a lower rate than free chlorine,” council papers state.


Tenders have been called for stage one of the masterplan which will see a 1.5 ML Chlorine Contact Tank and a 16ML Treated Water Storage Tank installed at the RRWTP, estimated to cost $14.7 million in October 2021.


The provision of a Chlorine Contact Tank will allow the primary disinfection at Rushforth Road by free chlorination while, by adding ammonia after the contact tank, continue to provide for a chloramine residual in the lengthy pipeline network,” council papers state.


Stage two of the masterplan is the conceptual design for filtration to be constructed at the RRWTP and is estimated to cost $63.8 million, with an annual operating cost of $2.1 million.


The Masterplan has confirmed that gravity flow through the plant is feasible, and all elements of the plant have been conceptually located so that the current plant (with the addition of the chlorine contact tank) can continue to operate during construction,” council papers state.


Due to its construction cost the filtration plant is classified as State Significant Development, and therefore needs planning approval via an Environmental Impact Statement (EIS).


It is recommended that Council commence the approval process for a future filtration plant by calling tenders to undertake an EIS.”


The last time council considered filtration at its April 15, 2014 meeting it was estimated the construction and operation of a filtration plant would add $275 annually to the typical residential bill.


The drinking water risk is not assessed by the State Government as being high enough for funding assistance under the current Safe and Secure Water Program,” council papers state.


The Rushforth Road water treatment has been allocated a risk score of “4”, while the program funding is currently only sufficient to provide assistance for projects with a risk score of “5”.”


Due to this situation, it is likely that CVC will require loans to fund the water filtration project.

RBA Governor Lowe set to meet with Suicide Prevention Australia after indications there is a surge in people reporting elevated distress over cost-of-living pressures

 


The 10th consecutive cash rate rise announced by the Reserve Bank of Australia has low income and middle income Australia reeling.


Post, a daily newsletter from The Saturday Paper, from the pen of the Emails Editor, 8 March 2023, excerpt:


RBA governor Philip Lowe has announced a record 10th consecutive interest rate rise, but signalled the run may be coming to an end amid concerns the hikes are hurting wellbeing.


What we know:


  • The RBA increased rates by 25 basis points at the board's March meeting, to 3.6% — the highest interest rate since May 2012 (Nine);


  • Mortgage holders with a balance of $750,000 will pay an extra $121 a month — and are now likely paying about $18,900 more in repayments annually since May (realestate.com.au);


  • Lowe’s language softened on the prospect of future rate rises however, with economists suggesting there might only be one or two left (AFR $);


  • He is set to meet representatives of Suicide Prevention Australia, the peak body that has raised the alarm about a surge in people reporting elevated distress over cost-of-living pressures (The Age);


  • Research by Suicide Prevention Australia, given to Lowe late last week, shows 46% of people are reporting high levels of cost-of-living distress;


  • There has also been a lift in the number of people reporting serious thoughts of suicide, which reached 16%, with sharp increases in NSW and Victoria;


  • Lowe will give further clues as to the RBA’s plans in a speech about inflation and recent economic data to a business conference today (Canberra Times);


  • The RBA governor has previously warned of a wage-price spiral driving inflation, though wage growth has been slowing, while corporate profits are surging (The Saturday Paper).

Media Release

Statement by Philip Lowe, Governor: Monetary Policy Decision


Number 2023-07

Date 7 March 2023


At its meeting today, the Board decided to increase the cash rate target by 25 basis points to 3.60 per cent. It also increased the interest rate on Exchange Settlement balances by 25 basis points to 3.50 per cent.


Global inflation remains very high. In headline terms it is moderating, although services price inflation remains elevated in many economies. It will be some time before inflation is back to target rates. The outlook for the global economy remains subdued, with below average growth expected this year and next.


The monthly CPI indicator suggests that inflation has peaked in Australia. Goods price inflation is expected to moderate over the months ahead due to both global developments and softer demand in Australia. Services price inflation remains high, with strong demand for some services over the summer. Rents are increasing at the fastest rate in some years, with vacancy rates low in many parts of the country. The central forecast is for inflation to decline this year and next, to be around 3 per cent in mid-2025. Medium-term inflation expectations remain well anchored, and it is important that this remains the case.


Growth in the Australian economy has slowed, with GDP increasing by 0.5 per cent in the December quarter and 2.7 per cent over the year. Growth over the next couple of years is expected to be below trend. Household consumption growth has slowed due to the tighter financial conditions and the outlook for housing construction has softened. In contrast, the outlook for business investment remains positive, with many businesses operating at a very high level of capacity utilisation.


The labour market remains very tight, although conditions have eased a little. The unemployment rate remains at close to a 50-year low. Employment fell in January, but this partly reflects changing seasonal patterns in labour hiring. Many firms continue to experience difficulty hiring workers, although some report a recent easing in labour shortages. As economic growth slows, unemployment is expected to increase.


Wages growth is continuing to pick up in response to the tight labour market and higher inflation. At the aggregate level, wages growth is still consistent with the inflation target and recent data suggest a lower risk of a cycle in which prices and wages chase one another. The Board, however, remains alert to the risk of a prices-wages spiral, given the limited spare capacity in the economy and the historically low rate of unemployment. Accordingly, it will continue to pay close attention to both the evolution of labour costs and the price-setting behaviour of firms.


The Board recognises that monetary policy operates with a lag and that the full effect of the cumulative increase in interest rates is yet to be felt in mortgage payments. There is uncertainty around the timing and extent of the slowdown in household spending. Some households have substantial savings buffers, but others are experiencing a painful squeeze on their budgets due to higher interest rates and the increase in the cost of living. Household balance sheets are also being affected by the decline in housing prices. Another source of uncertainty is how the global economy responds to the large and rapid increase in interest rates around the world. These uncertainties mean that there are a range of potential scenarios for the Australian economy.


The Board’s priority is to return inflation to target. High inflation makes life difficult for people and damages the functioning of the economy. And if high inflation were to become entrenched in people’s expectations, it would be very costly to reduce later, involving even higher interest rates and a larger rise in unemployment. The Board is seeking to return inflation to the 2–3 per cent target range while keeping the economy on an even keel, but the path to achieving a soft landing remains a narrow one.


The Board expects that further tightening of monetary policy will be needed to ensure that inflation returns to target and that this period of high inflation is only temporary. In assessing when and how much further interest rates need to increase, the Board will be paying close attention to developments in the global economy, trends in household spending and the outlook for inflation and the labour market. The Board remains resolute in its determination to return inflation to target and will do what is necessary to achieve that.

At 5 am - 6 am, 8 March 2023 (AEDT) this morning both Lismore and Grafton air quality monitoring stations were not reporting data – along with three other regions.

 


The NSW Government monitors air quality across the state.


In the Northern River region this monitoring in theory encompasses the northern part of the North Coast planning region from the NSW-Qld border region down to the Clarence Valley.


Air quality in Northern NSW is generally considered to be good.


However there are only two permanent official air quality monitoring stations in the Northern Rivers region, at Grafton and Lismore.


These stations principally monitor fine particles in the air on an hourly basis and publish the hourly average at

Lismore: https://www.airquality.nsw.gov.au/northern-rivers/lismore

and

Grafton: https://www.airquality.nsw.gov.au/northern-rivers/grafton.


Principally the monitoring is of:


PM2.5 are fine particles in air with a diameter of 2.5 micrometres or less. PM itself is short for 'particulate matter', another term for particles. They are generated by combustion processes from sources such as vegetation fires, motor vehicles and industrial activities. PM2.5 is reported in unit of microgram per cubic meter (µg/m3).


These small particles can get deep into the lungs and be absorbed into the blood stream. Short term impacts include difficulty in breathing and worsening of asthma or chronic bronchitis symptoms. They can also cause irritation of eyes, nose and throat.


PM2.5 Ratings


PM10 are particles in air with a diameter of 10 micrometres or less. PM itself is short for 'particulate matter', another term for particles. They can include dust or sea salt, as well as smaller particles generated from combustion processes such as vegetation fires, motor vehicles and industrial sources. PM10 is reported in unit of microgram per cubic meter (µg/m3).


These particles can pass into the lungs. Short term impacts include difficulty in breathing and worsening of asthma or chronic bronchitis symptoms. They can also cause irritation of eyes, nose and throat.


PM10 Ratings

However, it is somewhat disconcerting to notice that in 2023 the Lismore station in particular is experiencing gaps in the hourly record due to “Station not reporting data”.


Given warnings concerning the possible risk of grassfires across the state from September-October 2023 onwards, I'm sure it would be appreciated by many in Northern NSW if any technical/performance problems are corrected before the next fire season.

COVID-19 NSW State Of Play 2023: Counting Dead People - Part 4


IMAGE: www1.racgp.org.au



According to the World Health Organisation (WHO) Omicron variants of SARS-CoV-2 remain the currently circulating variants of concern.


By the end of February 2023 the SARS-CoV-2 sequences by variant pool found in Australia were estimated at 24.46% Omicron (BA 2.75), 1.09% Omicron (BA.5),13.59% Omicron (BQ.1), 3.26% Omicron (XBB), 26.63Omicron (XBB1.5) and 30.98% recombinant variants. NOTE: Only a fraction of all cases are sequenced and Recently-discovered or actively-monitored variants may be overrepresented, as suspected cases of these variants are likely to be sequenced preferentially or faster than other cases [Our World Of Data, 5 March 2023].


In the 7 days up to 25 February 2023 in NSW South Wales a total of 48 people were recorded as having died from COVID-19.


Of these 26 were adult men and 22 were adult women.


Two of the dead were in the 40-49 year age group and the other 46 deceased individuals were aged between 70 years of age & 90+ years.


Three of the dead were from the Northern Rivers region, which in that 7 day period had seen 223 local residents recorded as newly infected with COVID-19.


In the 7 days up to 2 March 2023 an est. 213 Northern Rivers residents were recorded as newly infected with COVID-19. 


NOTE: NSW COVID-19 data is held at multiple points on the NSW Government’s online public access health data site/s. For reasons best known to itself these sites rarely use identical time periods for their published summaries. This means there is a 2 day overlap in the two 7 day periods for the Northern Rivers which renders the infection number for 2 March an estimate. As yet no deaths have been published for local health district for these particular 7 days.


Over the 12 days from 19 February to 2 March 2023 multiple confirmed cases of COVID-19 were reported in the following Northern Rivers local government areas:

  • Tweed Shire – postcodes 2484, 2485, 2486, 2487, 2488, 2489;

  • Kyogle Shire – postcodes 2474;

  • Ballina Shire – postcodes 2477, 2478;

  • Byron Shire – postcodes 2479, 2480, 2481, 2482, 2483;

  • Lismore City – postcodes 2472, 2480;

  • Richmond Valley – postcodes 2469, 2470, 2471, 2473, ; and

  • Clarence Valley – postcodes 2460, 2462, 2463, 2464, 2465, 2466.


State-wide in NSW in the 7 days up to 2 March 2023 a total of 7,163 new cases of COVID-19 infection were recorded With 800 infected people hospitalised and a total of 29 deaths recorded.


At that point in time (2 March 2023) the total number of COVID-19 cases recorded in NSW since the pandemic began in January-February 2020 had reached est. 3,907,940 people infected, of which 6,493 have been recorded as dying as a result of contracting the viral infection.


By 3 March 2023 the cumulative total of COVID-19 deaths Australia-wide had reached est. 19,459 men, women and children.


The recorded cumulative number of people infected with the virus, as well as those dying as a result of infection, continues to rise in what is now the fourth year of uncontrolled viral infection spread in the general populace.
