Pennant Hills Rd traffic set to get thousands more trucks to build a tunnel to take trucks off the road

THE Roads and Maritime Service has said 70 trucks an hour carting concrete from the Mount Kuring-Gai industrial area to the NorthConnex tunnels via Pennant Hills Rd next year will “not add to traffic congestion”.
The slow rumble of 70,000 transit mixer truck will start to build around Hornsby later this month and reach a maximum hourly rate of 35 trucks going each way to and from the plant to the various project sites along Pennant Hills Rd.
A commercial concrete batching plant has been built at the Hornsby Council waste management depot on Beaumont Rd, to provide fresh concrete for the 9km twin tunnel motorway project.
NorthConnex will use about 160,000 cubic metres of concrete for structural elements and 200,000 cubic metres of concrete to line the tunnel.
A recent traffic study “indicated no additional queuing or delays” are expected at traffic lights along the concrete haul route as a result of the project, an RMS spokeswoman said.

“Deliveries will be made using approved routes including the M1 Motorway and Pennant Hills Rd during standard work hours,” she said. “No local residential roads will be used.”
The average number of trucks headed west on Pennant Hills Rd (east of Beecroft Rd) each hour is about 250, RMS data shows.
Concrete delivery is scheduled to start at the end of October and will peak in late 2017 with up to 70 truck movements per hour (in and out).
There are about 70,000 to 75,000 truck movements expected with the plant operating 24/7 until the end of the project in 2019.
Trucks hauling spoil to fill Hornsby Quarry will also use the M1 Pacific Motorway but George St and Bridge Rd will be used during off peak hours to minimise congestion, the RMS spokeswoman said. During peak hours the “preferred route” for Quarry trucks will be Bridge Rd, Jersey St North and Windybanks Rd.
Hornsby Mayor Steve Russell acknowledges it may inconvenience people.
“It’s a legitimate concern and I understand that but we have to go through some disruption for the massive gain of NorthConnex,” Mr Russell said.
Hornsby Council leased their land for the plant to NorthConnex for $187,500 per year, for three years, plus a three per cent annual increase.
“It’s income for the ratepayers of Hornsby,” Mr Russell said. “We’ve done a pretty good deal there, that land was just sitting there.”
The site will be remediated and become a waste facility once the project is finished, he said.
The site is close to sand and gravel sources at Peats Ridge and that reduces traffic haulage and the delivery of raw materials through Sydney, a NorthConnex notice said.
“Once tunnel breakthrough occurs, some concrete trucks will be able to access the tunnel through the Northern Interchange,” the note said.
The site will house the concrete plant, office facilities, material storage, wash down area, storage silos and concrete testing facilities.
The plant was approved by the Department of Planning and Environment.

Sion residents say pollution from concrete batching plant is making them ill

Residents of three societies from Sion have complained that a ready-mix-concrete (RMC) plant located near their complexes is causing air and noise pollution, leading to several of them falling ill.
An RMC plant is a factory or cement mixing plant where cement mix is made in large quantities, mostly used for construction.
An official from the private RMC plant said the operator had spent nearly Rs70 lakh to meet the Maharashtra Pollution Control Board’s (MPCB) norms. “We put up tin sheds that are more than 10-feet tall and barricaded the periphery of the plant. We installed dust suppression systems. We created a two-level tyre washing technique to reduce dust. Senior MPCB officials visited our plant and gave us consent to operate,” said the official.

Residents of Everard Nagar, Lokmanya Pan Bazaar and Harshad housing societies in Sion have filed repeated complaints with the MPCB over the past two years, demanding that the plant be shut down and relocated. However, no action has been taken against the plant operators.
“Trucks exiting the plant leave behind cement on the roads in front of our buildings. This has led to dust pollution, which has been causing eye irritation, breathing troubles, cough and cold for a lot of residents,” said Saraswathi Sundareswaran, resident of Everard Nagar. “Either the plant should be shut or the trucks need to use an alternative route,” she said, adding 500 residents began a signature campaign to shut the plant but the authorities did not act.
A resident of Lokmanya Pan Bazaar housing society said the process of cement batching and constant movement of trucks had led to high noise levels. “The plant has caused sleepless nights for our children as each time a truck passes through the narrow roads, our walls start to vibrate,” said BS Farale, secretary of the society.
An official from the concrete batching plant manufacturers said the residents had a problem with the trucks using the service road in front of the societies. “The road is also marked on the city’s development plan and can be used by trucks,” he added.
According to MPCB guidelines, RMC plants must create a 100-m buffer zone from residential areas and arterial roads. Most plants do not follow this.
MPCB officials said similar complaints were filed last year by residents and the plant had been given a notice. “After we intervened, the plant was shut down for a few months this year. It installed dust separator, collection systems and complied with all our guidelines,” said the sub-regional officer of the area, MPCB. “The plant has taken the consent of various departments of the civic body and is functioning without causing pollution,” he added.
The land owners, Somaiya Trust, which has a cancer hospital in the same vicinity as the plant also refuted the residents’ allegations. “The RMC plant only uses wet slurry. There is no question of dust emanating from there. It has not caused any issues for any of our patients either,” said V Ranganathan, representative, Somaiya Trust.
What is an RMC plant?
An RMC plant is a factory or horizontal concrete batching plant where cement mix is made in large quantities. From here, the mix is delivered to construction sites in trucks with mixers that keep rotating to prevent it from getting dry. Such a plant can produce 80 to 100 metric cubes of concrete daily.
A 2010-’11 study by the National Environmental Engineering Research Institute (NEERI) on the sources of pollution in Mumbai found that construction activities alone were responsible for a whopping 8% of the city’s pollution.
