meeting statutory 
requirements and 
acceptable standards. 
  Dust is currently restricted to 
localised, short-term events caused 
by the movement of cattle, and 
vehicle movements on unsealed 
roads. 
  Large scale episodic dust events 
caused by general dust lift during 
windy conditions occur occasionally 
and may lead to exceedances of 
NEPM levels.  
  Within freehold areas, dust is also 
generated from erosion processes 
due to agricultural activities such as 
ploughing prior to seeding and the 
summer grazing of stock.

emissions include: 
o Exposed 
surfaces 
o Construction 
earthworks 

Blasting and crushing of rock  

Vehicle movements and ore 
transport 
  The construction face will be constantly 
moving, meaning that construction impacts 
will generally be short-term in nature. 
  Best practice dust controls to ensure that dust 
emissions are minimised and avoided. 
  Perform visual dust monitoring of construction 
and operations areas to ensure that fugitive 
emissions meet required standards.

  Dust emissions will 
increase during both 
construction and 
operational phases but will 
be managed under an Air 
Quality Management Plan 
that will detail 
management actions for 
both phases.  Impacts are 
not expected to be 
significant following

  The application of 
individual landholder 
consultation and 
management controls 
through the land access 
negotiations for 
biosecurity, drainage 
management, and 
integration with farm 
planning is expected to 
result in impacts being 
acceptable. 
  No significant impacts are 
anticipated arising from 
disturbance of ASS as only 
1.3% of the 16% of

environment by causing contamination, 
increasing the risk of disease and 
encouraging feral animals. 
  Up to 6 Wastewater Treatment Plants 
(WWTPs) required for a peak workforce of up 
to 3000. 
  Liquid hydrocarbon wastes will be generated 
during both construction and operational 
phases. 
  Inert and putrescible solid wastes will be 
generated during both phases of the 
Proposal.  These will largely be associated 
with the accommodation requirements of the 
construction workforce. 
Hazardous Materials 
  Hazardous materials such as fuel, oils, 
lubricants, chemicals and explosives will be 
required for the construction (and some for 
operation) and may be stored inappropriately 
or spilt potentially casing contamination of soil 
or water, and exposing native animals and 
livestock to hazards. 
  Fuels oils are flammable and could lead to an 
increased risk of fire. 
  Transport of hazardous materials along major 
traffic routes is not expected to be significant 
and the potential for vehicle/rail interaction 
has been eliminated by the selection of a 
grade separation bridges where the rail 
crosses the North West Coastal Highway 
(NWCH) and the Chapman Valley Road.

  Prepare and implement a Waste Management 
Plan based on the hierarchy of waste 
minimisation. 
  Treated wastewater from Construction and 
Operations Camps will be discharged at 
designated spray irrigation areas to be 
established near the camps, or the wastewater 
will be treated to a standard that is suitable for 
use for dust suppression (subject to DoH 
requirements).   
  WWTPs will be subject to licensing under Part 
V of the EP Act.

(in accordance with WQPN – Irrigation with 
Nutrient Rich Wastewater). 
  Hazardous wastes will be stored and 
transported in accordance with relevant 
legislation to ensure that there is no discharge 
to the environment. 
  Hydrocarbons will be transported, stored and 
used in accordance with industry best practice 
to reduce the risk of spillage to the 
environment. 
  Hydrocarbon spills will be reported as 
incidents and responded to immediately.  Spill 
kits will be kept in designated positions to 
allow swift response.  Any contaminated soil or 
used clean up equipment will be taken to a 
licensed facility.   
  Hazardous material handling, storage and spill 
response will occur in accordance with 
Dangerous Goods Licences issued under the 
Dangerous Goods Safety Act 2004 and 
Australian Standards. 
  Prepare and implement a Hazardous Materials 
and Contamination Management Plan to 
document in detail how chemicals, 
hydrocarbons and hazardous goods or waste 
will be managed.  This plan will ensure 
compliance with the Contaminated Sites Act 
2003
managed by many other 
remote operations in WA.  
The quantities of waste 
expected to be generated 
are not significant. 
  Application of industry best 
practice preventative 
controls such as risk 
assessment and the 
application of storage and 
handling standards, 
incident reporting and 
remedial capacity are 
expected to reduce 
contamination risks to the 
environment to a level that 
is insignificant.   
  Current legislative controls 
are expected to ensure 
that waste and hazardous 
materials are managed to 
avoid significant impacts to 
the environment.

  Reporting under the NGER 
Act will be required. 
  OPR is expected to 
participate in the proposed 
Carbon Pollution 
Reduction Scheme. 
 SOCIAL SURROUNDS 
Heritage To 
ensure 
that 
changes to the 
biophysical 
environment do not 
adversely affect 
historical and cultural 
associations and 
comply with relevant 
heritage legislation. 
  Indigenous heritage sites are known 
at a number of locations in the Study 
Area. 
  The Proposal is within the external 
boundaries of the Naaguja, Amangu, 
Widi Mob, Mullewa Wadjari and 
Wajarri Yamatji Native Title claims. 
  DIA registered Aboriginal sites within 
the Proposal Area include Weld 
Range and Jack Hills, which are 
known to have mythological 
associations to local Indigenous 
people. 
Potential impacts relate primarily to direct 
disturbance and include: 
 
Disturbance of sites during construction 
 
Landscape level changes  
 
Collection and/or defacing of 
artefacts/artworks 
 
Accidental damage of artefacts by off-
road vehicle use 
 
Indirect disturbance to sites from 
changes in water flows, spillages, dust, 
or other indirect impacts. 
  Sites associated with watercourses within the 
Proposal Area are the most likely to be 
impacted as the sites tend to be concentrated 
around water courses and the Proposal must 
cross a number of water courses.   
  OPR will avoid Aboriginal sites wherever 
practicable.  Where it is not practicable to do 
so, OPR will consult with each of the native 
title claim groups in relation to the mitigation 
and salvage of any affected Aboriginal sites 
and seek the consent of the Minister for 
Indigenous Affairs pursuant to Section 18 of 
the AH Act. 
  OPR has agreed processes in place with each 
of the Native Title claim groups affected by the 
Proposal to facilitate the identification of 
unregistered Aboriginal sites and Aboriginal 
heritage surveys will be progressively 
conducted over the Proposal Area prior to 
commencement of construction. 
  OPR has in place Heritage Protocols with 
Native Title groups. The implementation of 
these protocols will be via an Aboriginal 
Heritage Management Plan which includes: 
 
Protection of sites in situ. 
 
Consultation and Section 18 
processes, if required, for those sites 
that cannot be avoided. 
 
Earthworks management – including 
the use of monitors. 
 
Salvage and storage management. 
  OPR will also implement procedures (as 
identified in the Heritage Protocol) for the 
identification and management of any 
additional sites located during the construction 
phase of the Proposal. 
  OPR intends to negotiate Comprehensive 
Agreements with each of the registered Native 
Title Claimant Groups.  Such agreements 
would outline opportunities for Indigenous 
involvement e.g. employment, training and 
contracting arrangements. 
  The Proposal will have an 
unavoidable impact on a 
number of Aboriginal 
heritage sites.  Where 
practicable, significant 
heritage sites will be 
avoided.  Ongoing 
consultation and 
indigenous participation in 
heritage survey work will 
assist OPR to ensure that 
impacts are acceptable. 
  With the implementation of 
management measures, 
the risk of inadvertent 
disturbance of sites is 
minimised and any 
unavoidable disturbance is 
authorised under the AH 
Act.

to reduce visual 
  Study Area includes areas of gentle 
undulation in the freehold area, with 
largely cleared farming land and 
relatively low population 
concentrations.   
  The Proposal will be a long linear feature with 
potential impacts to viewscapes from public 
and private locations at the western end.   
  Viewscapes are more significant in the 
western part of the Proposal Area as the route 
  Route selection and engineering constraints 
related to grade and earthmoving mean that 
impacts on visual amenity are limited. 
  Prepare and implement a Visual Amenity 
Management Plan (VAMP) that will include 
No viewscape impacts on 
major settlements, townships 
or communities.

currently generates income largely 
from farming, mining and fishing. 
  The Study Area does not contain or 
pass in close proximity to any major 
population centres.  The land use is 
rural, and the Proposal Area 
contains numerous track and minor 
road crossings. 
  Due to the rural land use of the 
Study Area recreational activities are 
limited; however several landholders 
located within or near the Study Area 
offer accommodation to tourists.

on acceptable access, activities and 
behaviours relating to construction areas 
through all freehold and pastoral properties. 
  Consultation with individual landholders 
completed as part of land access negotiations 
to include integration of farm plan aspects into 
construction management.  This will include 
drainage management, biosecurity, vehicle 
hygiene, stock and cropping management 
during construction and operation. 
  The public will be excluded from all 
construction areas, therefore these areas are 
not expected to provide a public risk. 
  In accordance with access agreements and 
leases negotiated with the State, signage will 
be erected and maintained to alert members of
