Original EA Amendment

The outcome for the land is simply the monitoring of mined areas. Like all land forming part of the Mount

Morgan Mine Site which is managed under the AMLP, the areas to be used on an interim basis by

Heritage Minerals under the EA will not have a ‘post-mining’ land use. Heritage Minerals is translating

that outcome to a Non Use Management Area (NUMA) under the PRCP for all mine features.

For the purposes of this EA amendment, the land outcome for the Upper Mundic Gully TSF mine feature

is proposed as a Post Mining Land Use (PMLU) instead of a NUMA. A NUMA can only be nominated

after all PMLU options have been assessed and it is considered that the land cannot be rehabilitated to

a stable condition. Achieving a PMLU outcomes for the Upper Mundic Gully TSF, although inconsistent

with all other mining domains occurring at the site, is proposed to align to the extent practical with the

Mined Land Rehabilitation Policy whereby rehabilitating the Upper Mundc Gully TSF does not pose a

greater environmental risk that not rehabilitating.

As the existing EA does not contemplate a PMLU justification is required to be provided within this

amendment application to demonstrate the most appropriate land outcome that can be achieved for the

site, recognising the various policy and land constraints that exist. These constraints include the fact

that the state is both the landowner and operates the site through the AMLP and that most of the land

within tenure has been subject to historical contamination.

A PMLU is defined under section 112 of the EP Act as the purpose for which the land will be used after

all relevant activities for the PRC Plan carried out on the land have ended.

The determination of the most appropriate PMLU to be nominated for the Upper Mundic Gully TSF has

been based on relevant legislation, planning scheme and guidance documentation, existing

surrounding land uses plus assessment of land suitability and capability of the disturbed areas.

Land Use Suitability

Five land suitability classes are defined for use in Queensland, with land suitability decreasing

progressively from Class 1 to Class 5. Classes 1 to 3 are suitable for agricultural production. Class 1

land is highly productive, requiring only simple management practices to maintain economic production,

with minimal degradation to the land resource. Class 5 land has extreme limitations that preclude the

possibility of successful sustained use of the land in the proposed manner.

Table F2 of the current EA provides a minimum Class 4 land suitability objective outcome for most mine

features with occasional Class 5 outcome for latent tailings domains. This land suitability outcome

suggested that soils across the site are not productive to support large scale agriculture or cropping

with severe limitations assigned to the site.

Land Use Strategies and Regional Planning

Rockhampton Region Planning Scheme 2015

The site is in the Limited development (constrained land) zone and Mount Morgan mine precinct under the Rockhampton Region Planning Scheme 2015 ( Planning Scheme ).

The outcomes for this land under the Planning Scheme are as follows:
