Environment Report - Santos

Executive Summary
appropriate mitigation and management
measures, impacts to air quality are unlikely
to occur as a result of the construction
or operation of the Casino Gas Field
Development.
Greenhouse Gas
Greenhouse gas emissions will vary over
the life of the Casino Gas Field Development.
The project will generate minor
greenhouse gas emissions during the
construction and installation stages, primarily
from vehicle exhaust emissions,
however, these emissions are short-term
and not significant contributors to Victoria’s
or Australia’s total emissions. Emissions
during operation of the pipeline will
be minimal comprising potential fugitive
emissions and minor quantities of vehicle
emissions. As a signatory to the
APPEA Greenhouse Challenge, Santos
will continue to address reduction management
of greenhouse gas emissions.
Traffic
The roads within the project area are
multi-user roads. The potential impacts
associated with construction traffic include
road safety and potential interruption
to traffic movements. A construction
traffic management plan will be developed
in consultation with relevant regulatory
authorities and implemented as
appropriate. It is expected that impacts
resulting from construction traffic can be
mitigated with the implementation of this
plan.
Condensate will be transported from the
TXU WUGS facility to a refinery by single
road tankers, resulting in 2 to 3 trucks
per week. The volume of condensate
and therefore trucks is expected to decline
to about one per week after the first
two years of field production. Based on
this low and declining volume of condensate
transport road traffic, and the application
of the existing road safety
management requirements for current
traffic from the TXU WUGS facility, this
minor increase in volume is not expected
to significantly impact local traffic conditions.
Hazard and Risk
The Pipelines Act 1967 requires that a
detailed risk assessment be undertaken
in accordance with the requirements of
the Australian standard for high-pressure
gas pipelines, AS2885.1. Consequently,
the Casino Gas Field Development is
designed and operated to achieve hazard
and risk levels that are as low as
reasonably possible. Prior to the granting
of the Pipeline Licence Santos will
undertake such a risk assessment the
results of which will be incorporated into
final project planning and design as required.
5. Environmental
Management
Santos has developed an environment,
health and safety management system
(EHSMS) which consists of two sets of
standards: management standards and
hazard standards. A project-specific environment
plan (EP), for offshore components,
and environmental
management plan (EMP), for onshore
components, will be prepared for the
Casino Gas Field Development within
the framework of the EHSMS.
Pipeline alignment is the most effective
mitigation measure for minimising impacts.
Residual impacts are then mitigated
and managed through the
implementation of appropriate measures
and procedures. Table 1 summarises the
impacts associated with the project, together
with the mitigation and management
measures, additional to pipeline
alignment that will form the basis of the
EP and EMP.
