Environment

Intrapac Properties is an award-winning land developer, with a high commitment to environmental outcomes.

On October 16, 2017 the Northern Territory’s Environment Protection Authority (EPA) issued the environmental assessment, which includes requirements to achieve environmental sustainability,

and the protection of areas of biodiversity significance. This includes 11 recommendations.

Throughout 2019, Intrapac has been completing specific environmental studies and further work to address the 14 recommendations, and to support the rezoning application.

Recommendation

Action Taken / Comments

Recommendation 1
The Proponent shall ensure that the Noonamah Ridge Estate proposal is implemented in accordance with all environmental commitments and safeguards:

  • Identified in the Environmental Impact Statement for the Noonamah Ridge Estate (draft Environmental Impact Statement, Supplement and additional information)
  • Recommended in this Assessment Report 82.

The Proponent shall ensure that the Noonamah Ridge Estate proposal is implemented in accordance with all environmental commitments and safeguards:

Incorporated into the requirements of the Specific Use Zone, to ensure that all subsequent development applications comply with the EIA
recommendations.

Recommendation 2
The Proponent shall provide written notice to the Northern Territory Environment Protection Authority and the responsible Minister if it alters the Project and/or the master plan and/or environmental commitments in such a manner that the environmental significance of the action may change, in accordance with clause 14A of the Environmental Assessment Administrative Procedures.

Noted. This would be undertaken should such a situation occur.

Recommendation 3
The areas of high conservation value, (or an area that the NT EPA agrees is adequate to protect those values, such as the agreed integrated conservation network identified at Figure 3), is to be appropriately formalised in the NT Planning Scheme.

Incorporated into the requirements of the Specific Use Zone, including the concept map. This will be further articulated through the Master Plan to be lodged with the first stage subdivision application as required by the Specific Use Zone.

Recommendation 4
The Planning Scheme Amendment shall include a requirement to develop and implement a management framework to protect the significant environmental values on the site that describes:

a) measures to protect the identified significant environmental values on the Project site, informed by Recommendation 4 (b) below

b) the systems to ensure significant environmental values are protected, including: studies, investigations, monitoring and control systems including reporting arrangements to support adaptive management of emerging risks to significant environmental values

c) the entity accountable for implementation of systems outlined in Recommendation 4 (b)

d) options for appropriate funding arrangements to achieve an agreed level of environmental management over the long term, one or a number of which need to be agreed prior to implementation of the Project. The management framework is to be prepared to the satisfaction of the NT EPA, Department of Infrastructure, Planning and Logistics, and Department of Environment and Natural Resources prior to implementation of the first Development Application.

Incorporated into the requirements of the Specific Use Zone. This will be finalised and lodged with the first stage subdivision application as required by the Specific Use Zone.

Recommendation 5
The Proponent shall define and fund an investigation to understand the predevelopment hydrology of the sandsheet heath associated with supporting C. insolata. The investigation should be designed in a manner that would inform the Development Consent Authority of the risks and potential impacts of siting a lake near the heath habitat.

Although already known to occur in the site, during fieldwork for the hydrology and toadlet studies, ecologists noted a wider prevalence and greater number of the threatened plant, Cleome insolata. In conjunction with botanists from the NT Herbarium, EcOz Environmental Consultants re-mapped the local occurrence of the species, noting a significant proportion of the local population occur in areas to be zoned Conservation. This area has been outlined in the Specific Use Zone and will be subject to further investigation before lodgement of the first subdivision application.

Recommendation 6
The objectives, scope, timing and design of the study to identify the Dry season dispersal and habitat use by the Howard River toadlet (U. daviesae) should be identified in the management framework outlined in Recommendation 4. The study should be adequate to justify the use of adjacent land so that unacceptable impacts to hydrology and U. daviesae are avoided.

To address Recommendation 6 and to inform Recommendation 7, an investigation into the movements of the threatened Howard River Toadlet (Uperoleia daviesae) was undertaken by EcOz Environmental Consultants between March and May 2018. The survey was designed in collaboration with the Flora and Fauna Division of DENR, and involved the installation and checking of pitfall traps.  More than ten people were involved in this survey during the two trapping sessions.  A large number of amphibian species were captured, many of which can only be positively identified through DNA analysis. The results of such analysis from the first round of trapping are pending; those from the second round of trapping did not detect any dispersal of the Howard River Toadlet from the sandsheet heath habitat in which it was originally recorded.

Recommendation 7
Outcomes of the study of U. daviesae Dry season habitat and hydrology requirements of seasonally inundated habitat are to inform the boundaries of the agreed integrated conservation network. Revision of the conservation network should incorporate the Dry season habitat for U. daviesae and be sufficient to maintain the surface/sub-surface hydrology of breeding habitat.

Although the DNA results from the first round of toadlet trapping undertaken to meet Recommendation 6 are yet to be ascertained, the results from the second round of trapping, as well as the hydrology study undertaken to meet Recommendation 5, indicate that the conservation network presented in the Planning Scheme Amendment incorporates the Dry season habitat for the Howard River Toadlet and is sufficient to maintain the surface/sub-surface hydrology of the breeding habitat.

Recommendation 8
In accordance with Recommendation 4, the Proponent shall design and implement a Water Quality Monitoring Plan. The Water Quality Monitoring Plan shall include provisions to monitor the performance of WSUD and stormwater basins during the first stages of the Project. The results of the monitoring shall be used to inform the design of subsequent stages to improve the management of stormwater and improve the quality of run-off from the site.

Incorporated into the requirements of the Specific Use Zone. This will be finalised and lodged with the first stage subdivision application as required by the Specific Use Zone.

Recommendation 9
The Proponent shall prepare and implement an Erosion and Sediment ControlPlan (ESCP) for each stage of the Project. Each ESCP should:

  • be prepared by a suitably qualified and experienced professional in erosion and sediment control planning; and be reviewed and approved by a Certified Professional in Erosion and Sediment Control
  • be prepared in accordance with the IECA Best Practice Erosion and
  • Sediment Control Guidelines 2008, as amended from time to time (or higher standard)
  • be the final environmental management plan to be prepared (as it relies on completion of final design) and be a stand-alone document which contains all necessary information to facilitate its implementation without requiring the user to reference other documents
  • be cross-referenced with other relevant environmental management plans to ensure consistency (e.g. plans relating to water management, stormwater management, site rehabilitation, etc.)
  • include details of both temporary and permanent erosion and sediment control methods and treatments to be implemented for all stages of the project (pre, during and post works)
  • comprise an over-arching strategic document outlining the principles, practices and methods to be implemented, as well as site-specific dimensioned plans identifying the location of works and prescribed controls; and be accompanied by relevant Standard Drawings and Construction Notes
  • include information regarding proposed timing and staging of works, site manager contact details, maintenance and monitoring requirements, and reporting procedures.

Implementation of the ESCP should be regularly monitored by a suitably qualified third party auditor, to the satisfaction of the Consent Authority.

Incorporated into the requirements of the Specific Use Zone. This will be finalised and lodged with the first stage subdivision application as required by the Specific Use Zone.

Recommendation 10
The Proponent shall include the historical aircraft wreckage within a conservation reserve with a 200m buffer around the centroid of the debris.

Incorporated into the requirements of the Specific Use Zone. This will be finalised and lodged with the first stage subdivision application as required by the Specific Use Zone.

Recommendation 11
Prior to the commencement of the first subdivision, the Proponent must undertake a full archival photographic record of the WWII aircraft wreck. The full archival photographic record must be consistent with the Queensland Government’s ‘Guideline: Archival Recording of Heritage Places’.

The full archival photographic record must be undertaken by a suitably qualified professional with experience in the preparation of archival recordings. The archival record must be submitted to the Department responsible for administering the Heritage Act within three months of commencing construction.

Incorporated into the requirements of the Specific Use Zone. This will be finalised and lodged with the first stage subdivision application as required by the Specific Use Zone.
