3            Measures to avoid, minimise or mitigate
             potential impacts
This section provides information related to measures designed to avoid and reduce potential impacts. This
section includes measures to reduce impact to the environment generally (refer Section 3.2.1 and 3.2.2) and
specific measures to reduce impact to the identified MNES (refer Section 3.2.2).


3.1          Avoidance/minimise of impacts
The proposed action was designed to firstly avoid impacts to flora and fauna and their habitat. Where
avoidance was not possible, the design and construction footprint has been minimised to the greatest extent
possible, particularly in the following areas:
   Six Mile Creek Conservation Park (National Park)
   Council Environmental Reserve
   Six Mile Creek channel
The bridge was also designed to span the creek to avoid the low flow channel.
The approach roads have been built as close to the existing alignment as possible to minimise impact on the
environment. The geometric design was considered in regards to environmental impact (refer Section 1.3).
Further, the existing bridge will be used as a side track during construction eliminating the need for
temporary works.


3.2          Mitigation measures of impacts

3.2.1        General measures to reduce environmental impacts
Mitigation measures presented within this section are designed to reduce impacts upon the environment,
including animals, plants and animal breeding places. The mitigation measures presented within this section
will also reduce impacts to the identified MNES but are not designed to specifically target these values.
Measures presented in the sections below include State-based legislative approval requirements,
compliance with State-based policies/guidelines as well as general best-practice techniques.


3.2.1.1      Compliance with State-based approval processes
Compliance with Queensland legislative requirements must occur for the proposed action to proceed (refer
Table 1.1). This includes the preparation of specific documentation, supported by field-based site
investigations where triggered by State-based environmental mapping. Approval to undertake works within
or adjacent to these areas is required. State-based legislative instruments applicable to the proposed action
that are relevant to MNES are outlined in Table 1.1. Compliance with these legislative instruments will
ensure that the environmental impacts are minimised to acceptable levels. Assessment of State-based
matters associated with the area proposed action, in accordance with the Queensland Environmental Offsets
Policy Significant Residual Impact Guideline (Nature Conservation Act 1992, Environmental Protection Act
1994, Marine Parks Act 2004) (State of Queensland 2014), is provided in Appendix A (Section 6.2).
