Monitoring the environment
The Ichthys LNG Project is undertaking a world-class environmental monitoring program throughout its construction phase.
Reports are made available to the community and to various external agencies and authorities including:
- Northern Territory Environment Protection Authority
- Ichthys Project Dredging Expert Panel (IPDEP) http://www.ichthys-panel.com.au/
- Commonwealth Department of the Environment.
Environmental monitoring will occur through the Project’s operations phase and will continue to be reported to the public.
Onshore Environmental Monitoring Program
An Onshore Environmental Impact Monitoring Program has been developed by the lead onshore construction contractor, JKC, to monitor potential effects on the terrestrial and nearshore environment associated with onshore construction activities at Bladin Point, Northern Territory. The Program includes surface water and groundwater, mangrove community health, sediments and bio-indicators, air quality (dust) and airborne noise monitoring.
Surface water monitoring
Surface water monitoring is carried out monthly to detect potential upstream and downstream impacts from discharges associated with basins, spills and leaks from construction activities in the nearshore environment around Bladin Point.
Groundwater monitoring is carried out monthly to monitor for changes in groundwater chemistry and elevation and to detect potential impacts on the receiving environment associated with construction activities.
Mangrove community health, sediments and bio-indicators monitoring
Mangrove community health monitoring surveys are carried out quarterly and incorporate monitoring of mangrove canopy density and biodiversity, benthic community health, sediment deposition, sediment quality and bio-indicators, to detect potential impacts to the receiving environment around the Project area.
Air quality (dust) monitoring
Air quality sampling is carried out continuously with monthly interpretation, so to identify and minimise potential impacts from dust on the environment and nearby sensitive receptors.
Airborne noise monitoring
Airborne noise monitoring is carried out continuously throughout construction to assess impacts on the nearby residential receptor.

Nearshore Environmental Monitoring Program
The Nearshore Environmental Monitoring Program was developed to monitor potential effects of dredging and spoil disposal activities on the marine environment in Darwin Harbour, Northern Territory. The Nearshore Environmental Monitoring Plan was developed as a requirement of the Commonwealth and Northern Territory approval conditions.

Turbidity and sedimentation in Darwin Harbour is naturally high due to the nature of the local environment and has been monitored closely to any potential impact on water quality from dredging.
The Water Quality and Subtidal Sedimentation Monitoring Program monitors turbidity, light, temperature and sedimentation (accumulation of sediment) levels in Darwin Harbour and was used as an early warning system to predict, detect and manage the possibility of dredging-related impacts on habitats, such as coral or seagrass, before they could occur.

Sediments on the sea floor disturbed and dispersed during dredging can settle on intertidal areas where mangroves grow and have potential to affect mangrove community health.
The Intertidal Sedimentation and Mangrove Community Health Monitoring Program has been designed to monitor sedimentation and detect changes in mangrove health in Darwin Harbour using a variety of field sampling techniques and satellite imagery.

An increase in the number of vessels entering Darwin Harbour for the Ichthys LNG Project dredging activities posed a potential risk through the introduction of marine pests.
To enable early detection, a Marine Pest Monitoring Program was implemented in Darwin Harbour to assess and monitor presence/absence of target marine pest species.
The monitoring program involved visual inspections, sediment and water sampling.

A Recreational Fishing and Fish Health Monitoring Program has been undertaken to gather information on the health of fish and crab species in and around Darwin Harbour. While dredging was not anticipated to have an impact on fish health, the program continually monitors species abundance, distribution and health to check that there is no change above what is considered to be natural.

The Indo-Pacific Bottlenose, Indo-Pacific Humpback and Australian Snubfin dolphins were monitored in Darwin Harbour to detect potential changes in the local population associated with Ichthys LNG Project dredging activities.
The world-class Coastal Dolphin Monitoring Program monitors dolphins using vessel-based surveys in and around Darwin Harbour, Bynoe Harbour and Shoal Bay with the help of indigenous rangers.
The program is considered to be one of the most comprehensive coastal dolphin monitoring programs in Australia, engaging government, commercial and industry partners.

The Intertidal Benthos Monitoring Program was designed to monitor organisms that live in the mud on the intertidal flats in Darwin Harbour to detect potential dredging impacts. The program includes collecting and sieving sediment samples from the mudflats to extract the animals, which are then identified by experts.

Subtidal benthos consists of two types of communities of organisms - those that live within the sediment and animals that live on the surface of the seabed.
The Subtidal Benthos Monitoring Program used underwater video cameras to take photos as well as sample sediment of the sea floor to monitor for potential dredging impacts to these communities.

Primary production is the process by which plants, such as algae and mangroves, convert sunlight into energy and carbon. The Primary Productivity Monitoring Program aimed to investigate potential impacts on primary productivity of certain species of mangroves and algae in Darwin Harbour. The monitoring program incorporated field surveys, sampling and satellite imagery.

The Underwater Noise Monitoring Program was developed to monitor the underwater noise generated by Ichthys LNG Project activities in the marine environment of the Darwin Harbour to ensure noise levels remain within approved acceptable limits as described in the draft EIS and construction Noise Monitoring Plan. Underwater noise monitoring included the use of sea noise loggers and vessel based surveys using hydrophones.
