2. Introduction Australia Pacific LNG Pty Limited (Australia Pacific LNG), a 37.5:37.5; 25 joint venture between Origin Energy Resource Limited (Origin), ConocoPhillips and Sinopec proposes to develop a world scale long-term coal seam gas (CSG) to liquefied natural gas (LNG) project in Queensland. The 30 year Project has the following objectives:

• Development of the Walloons gas fields in the Surat Basin in southern central Queensland with up to 10,000 CSG wells

• Construction and operation of approximately 530km main gas transmission pipeline (‘the gas pipeline’) to connect the Walloons gas fields with the LNG facility near Laird Point

• Construction and operation of an LNG facility near Laird Point on Curtis Island near Gladstone for production and export of approximately 18Mtpa of LNG.

Within the Condabri Development Area, it is proposed that production wells will be drilled and connected to the gathering system. Authorised petroleum activities to be carried out at under the EA may include development of:

• exploration, appraisal, and production wells

• water monitoring bores

• gas and water gathering networks

• waste transfer stations and pipelines

• irrigation water pipeline

• main pipeline

• central compressor stations

• water treatment facilities

• dams

• laydown and stockpile areas

• sewage treatment plants

• access tracks

• miscellaneous infrastructure

• workforce accommodation





3. Purpose The purpose of this Program is to document Australia Pacific LNG's framework for monitoring the progress of rehabilitation in the Condabri Gas Fields (PPL185, PPL186, PL265, PL266, PL267 and ATP1178). It also addresses conditions A10(i), A41-46 and H13-H17 within the Condabri Environmental Authority, EPPG00853013, conditions H10-H13 within the Condabri South Extension Environmental Authority, EPPG00904113, and condition F5 within the Fairy Meadow Road Irrigation Pipeline Environmental Authority, EPPG00913213, collectively hereafter referred to as the Condabri EA. Other conditions found within the Condabri EA in relation to rehabilitation are addressed and discussed within the Condabri Rehabilitation Plan Q-4500-15-MP-0002.

A summary of relevant Condabri EA conditions (not repeated if already referred in another EA) and an overview of where they are addressed within this rehabilitation monitoring program are provided in Table 5.

This rehabilitation monitoring program will form part of the Condabri Plan of Operations (Q-4500-15-MP-1025).

This rehabilitation monitoring program addresses both monitoring of final rehabilitation success and progressive rehabilitation monitoring following reinstatement after the installation of infrastructure.

5. Pre-Disturbance Monitoring

5.1. Visual Land Form Monitoring Visual landform monitoring will occur through taking photographs at photo points located at crossings of waterways (third order streams or greater and any smaller streams with defined beds and banks). Photographs will be taken upstream and downstream of each photo point, ensuring that date and location of photographs are accurately recorded.

5.2. Flora Species Of Conservation Significance The following will be undertaken to develop criteria for the management and rehabilitation of individual flora species of conservation significance (as outlined in the Threatened Flora Management Plan, Q-LNG01-15-MP-0108):

• Search routine public databases (e.g. Queensland Museum, Wildnet, and EPBC Protected Matters Search Tool) prior to the field survey to identify the known locations or potential for presence of any threatened flora species populations within proposed development areas.

• Target all ecological field surveys in remnant or re-growth vegetation which contain suitable habitat/REs (as identified above), whether conducted by ecologists or environment field staff, will include a targeted search for all threatened flora species identified within this plan, on a site by site basis.

• All threatened flora individuals identified during the field survey will be avoided by proposed infrastructure, where possible.

• Record important population features (size, health, and substrate) identified during the field survey process, together with any individuals requiring removal. Record digitally (i.e. GPS system) and store this information within the Australia Pacific LNG GIS.

5.3. Native Vegetation

5.3.1. Site Selection

Information on the vegetation structure and species composition, including abundance, and fauna habitat features, will be collected at analogue (reference) sites to compare and monitor the effectiveness of rehabilitation efforts during the life of the Project, and to set rehabilitation goals for each Regional Ecosystem (RE). Analogue sites will be established and guided by the Methodology for the Establishment and Survey of Reference Sites for BioCondition (Eyre et al., 2006). Analogue sites will be selected to be representative of each of the Endangered, Of Concern, Not of Concern and Least Concern RE types to be disturbed (representing remnant vegetation and high value regrowth). Analogue sites will also be located in the component REs of Threatened Ecological Communities (TECs) where these REs are to be disturbed.

Analogue sites will be located once environmental surveys have been completed, all REs have been verified and infrastructure locations are finalised. It is anticipated analogue vegetation site selection will be completed by December 2011.

The Queensland Herbarium’s Methodology for the Establishment and Survey of Reference Sites for BioCondition (Eyre et al., 2006) will be used to guide the selection of survey sites. This methodology requires that a minimum of three analogue sites be set up and surveyed for each RE. Additional analogue sites may be established as necessary where there is a risk of inadvertent disturbance to sites. Areas to be rehabilitated should be compared with an analogue site that occurs as close as possible to the area to be assessed and has similar environmental conditions, i.e. the same RE, vegetation community, similar climate (same subregion), similar landscape conditions (soil, slope, position in the landscape, geology etc.) and similar natural disturbance (such as fire history, cattle grazing). Analogue sites will be selected to be representative of the areas to be disturbed, for example where the vegetation is in a disturbed state, analogue reference site data presenting a similar condition will be selected.





As per Eyre et al. (2006) when selecting an analogue site, where practicable, Australia Pacific LNG will take into account that it must:

• be homogenous with regard to RE and condition status

• ideally, be located within a reasonably large (> 5 ha) intact patch of remnant vegetation (to avoid issues of edge effects)

• be located at least 50 m from a roadside, and

• established at least 3 km apart to account for potential geographic variation.

Analogue sites for each RE will be located in vegetation that is unlikely to be disturbed so that they act as a long-term reference for possible vegetation changes that are not brought about by Project disturbances. Where possible, undisturbed analogue sites will be located within areas of Australia Pacific LNG tenements that will not be disturbed by Project activities, and where there is considered less risk of inadvertent clearing or other human induced disturbance. Where suitable remnant vegetation is not available within Australia Pacific LNG tenements, analogue sites may be located within adjacent areas of remnant vegetation such as State Forests that provide the best examples of the RE.

BioCondition analogue sites will be selected by desktop using EHP mapping and CORVEG data. Data from environmental surveys undertaken before the finalisation of infrastructure locations will be considered in the location of analogue sites in areas adjacent to planned infrastructure. These surveys include Tertiary level surveys in accordance with Nedler et al. (2005) undertaken to verify REs.

Mixed polygons may be included as analogue sites where the area to be disturbed is also a mixed polygon (of equivalent percentages) where the area cannot be distinguished as a single RE.

5.3.2. Survey Methodology

Guided by the Methodology for the Establishment and Survey of Reference Sites for BioCondition (Eyre et al., 2006), at each analogue site the following will be measured:

• flora species richness (for each major life-form group or strata)

• canopy stem density (number of large trees)

• tree canopy height

• weed cover

• recruitment of canopy species

• vegetation cover in major strata (typically tree and shrub layers)

• percentage ground cover, and

• fauna habitat, including number and length of fallen logs (coarse woody debris), and percentage litter cover.

For details of the survey method, refer to Eyre et al. (2006).

Where possible, BioCondition reference site surveys will not be undertaken during dry periods (late winter-spring, except after a wet winter) and ideally will be undertaken between late summer and mid-winter.

All BioCondition reference site surveys will be undertaken by a suitably qualified ecologist.

5.3.3. Photo Monitoring

As part of the BioCondition reference analogue site survey, photographs will be taken at permanent photo monitoring points to be established at the centre of each BioCondition survey transect. These photos will provide a visual benchmark for rehabilitation.

At these photo points, a photo at the start and the finish of the transect will be collected as well as four photographs taken pointing north, south, east and west ensuring that date and location of photographs are accurately recorded.





5.3.4. Pasture Grass Check rehabilitation monitoring will be undertaken based on a stratification of soil and pasture types. Grass Check is a pasture monitoring program developed by the Department of Environment and Resource Management (DERM) for graziers which offers simple ways of checking and recording the condition of pastures, timber and soil, estimating sustainable production rates and providing an early warning of problems. Pasture check measures the cover of grass species including annual, perennial, native and introduced grasses with higher scores for palatable grass species.

5.3.5. Soil And Land Capability

A pre-disturbance soil survey of areas to be disturbed has been undertaken following the methodology outlined in the Australia Pacific LNG Condabri Gas Field Development Area Soil Assessment and Management Plan Q-LNG01-15-MP-0039. This survey and management plan provides soils ground-truthing and mapping at a scale of 1:250,000, including the mapping of soil units within facilities locations at 1:10000 and mapping of soil units through the well and gathering network at 1:100000. Results of soil ground truthing to be considered when setting of criteria for the rehabilitation of agricultural and in particular, cropping land. It will also ensure that sufficient information on soil type and associated limitations is available to guide soil handling including topsoil stripping, stockpiling, ripping, re-spreading and soil amelioration. It will also provide a reference against which to assess the condition of agricultural land after disturbance.





6. Monitoring During Operation

6.1. Visual Land-Form Monitoring The following monitoring regime will be implemented to ensure management actions for the prevention of erosion and sedimentation during vegetation clearing, topsoil stripping, subsoil management, stockpiling activities, rehabilitation activities, weed control, water diversion, erosion and sediment control activities and watercourse protection activities are being implemented and are appropriate for the site conditions.

• Daily visual monitoring using a checklist to ensure all actions are being implemented in accordance with the requirements outlined in this procedure

• Weekly formal inspections using a checklist and photographic records to ensure there are no incidences of soil subsidence or erosion resulting from construction activities and to identify any erosion repair works that might be required.

• Following high rainfall events (where minor flooding or greater may have occurred) all watercourse crossings of pipelines and tracks will be inspected to assess the stability of the channel and banks.

• Record keeping of the above in a database including the recording locations of all monitoring.

6.2. Weed Monitoring The distribution of weeds will be recorded through an active inventory of declared and environmental weeds, including the distribution of weeds within rehabilitated areas. To ensure this is regularly updated, all relevant staff and contractors will be informed in the identification of weeds and required to report their occurrence to the applicable Australia Pacific LNG Field Environment Group/Advisor.

Monitoring of the extent and distribution of weed populations including new infestations and weeds within rehabilitated areas will include the following.

• Weed checks will be conducted prior to and post construction. Monitoring will include previously disturbed and rehabilitated areas, retained vegetation, and buffer areas. This will include recording the location and extent of all Weeds of National Significance and Class 2 and Class 3 declared weeds under the LP Act.

• Updating and maintaining an active inventory of declared and environmental weeds within a weed identification layer in the Project GIS.

6.3. Monitoring On The Completion Of The Rehabilitation Process A sign-off of rehabilitation works is required on completion to ensure rehabilitation has been undertaken to the required standard. The following checklist documents will be completed at different stages of infrastructure development. In the progressive early stages of infrastructure development the FIC Environmental Clean-up and Rehabilitation (Q-LNG01-95-AQ-9218) will be completed. Upon work site transfer the CSG Operations Worksite Environmental Inspection Checklist (OEUP-Q1000-FRM-ENV-012) will be completed for site handover.





7. Monitoring of Rehabilitation Success Monitoring will be required at various intervals for a range of parameters to ensure that success criteria are met. While some success criteria require maintenance of an indicator at a particular level for at least three years, land form stability must be demonstrated for at least five years (Condabri EA Schedule H, H10d). It may, however, take several years for a particular level to be reached before maintenance can then be demonstrated. Further, monitoring must be undertaken for a minimum of five years after rehabilitation is completed as required by Condition H16 of the Condabri EA. Monitoring will take place at a minimum annual frequency as required by Condition H17 of the Condabri EA except for land suitability indicators where there will be a once off monitoring and sign-off after five years.

Details of indicators to be monitored and the frequency of monitoring are provided in Section 7.5.

7.1. Land Form Monitoring

7.1.1. Erosion and Subsidence

Monitoring of erosion and subsidence will occur at areas potentially prone to subsidence or erosion including:

• rehabilitated buried transmission pipeline corridors

• decommissioned ponds or dams (surface area disturbance >10ha will require a monitoring point for every 10 ha area, i.e. 22ha decommissioned pond requires 3 monitoring points); and

• crossings of waterways (third order streams or greater and smaller streams with defined bed and banks).

Monitoring of these areas for subsidence and erosion at least every 20 business days for the first 120 business days after rehabilitation is completed as required by condition D48 of the Condabri EA. After this time, monitoring of erosion and subsidence will be restricted to observations at other monitoring sites (i.e. Photo Monitoring, BioCondition and Grass Check monitoring sites, as outlined in Sections 7.1.2, 7.3.2 and 7.4). Monitoring may need to continue beyond five years if stability is not initially demonstrated in the first few years, since criteria H10 (d) of the Condabri EA requires that the land form is stable (no erosion or subsidence gullies) for at least five years.

The location and details of erosion will be recorded and uploaded to the GIS, including GPS coordinates, type, depth, severity and status as listed in Table 9. These details have been simplified from criteria for assessing erosion in the Australian Soil and Land Survey Handbook (The National Committee on Soil and Terrain, 2009).

Table 9: Erosion Data To Be Recorded

*A severity rank would be assigned based on the assessment of depth and extent

For areas of subsidence, the depth and extent (length and width) would similarly be recorded together with GPS co-ordinates. Photographs of erosion or subsidence areas will also be taken. Where erosion or subsidence is monitored, the land-form, slope class and soil type (using soil management groups outlined in the Condabri Gas Field Development Area Soil Assessment and Management Plan Q-LNG01-15-MP-0039) would be recorded.





7.1.2. Visual Land-Form Monitoring

Ongoing visual landform monitoring will also occur through the taking photographs at permanent photo points. Photo points will be located in the following areas:

• at crossings of waterways to be disturbed (third order streams or greater and smaller streams with defined bed and banks)

• at all decommissioned dams or ponds (surface area disturbance >10ha will require a monitoring point for every 10 ha area, i.e. 22ha decommissioned pond requires 3 monitoring points)

• well leases

• at sites identified as having highly erosive soils, as identified in the Condabri Gas Field Development Area Soil Assessment and Management Plan (Q-LNG01-15-MP-0039)

• at decommissioned gas field facility sites (surface area disturbance >10ha will require a monitoring point for every 10 ha area, i.e. 22ha decommissioned gas field facility requires 3 monitoring points), and

• at 1 km intervals along rehabilitated pipeline corridors, with additional points where slopes are greater than 10%.

Where these situations overlap in existence a single monitoring point is required, not multiple monitoring points.

Photographs will be taken facing north, east, south and west. However for linear infrastructure, photographs may be taken in each direction that the infrastructure runs, while for watercourse crossings, photographs may be taken upstream and downstream of each photo point. In these cases the direction of photograph must be recorded to ensure consistency with repeated photographs.

Should any erosion or subsidence be noted, this will be recorded as per Section 7.1.1.

Photo monitoring will be undertaken every 6 months for the first two years and then annually until stability is demonstrated for at least five years.

7.1.3. Flora Species Of Conservation Significance

Monitoring may be required where populations of EVNT listed flora species are located during construction or rehabilitated after construction. Survey methods will follow the “random meander” method as described by Cropper (1993). Monitoring frequency and methodology will be determined on a case-by-case basis but will need to consider appropriate timing and effort. For known populations of threatened flora species, monitoring of each population will be undertaken to assess whether number of individuals, health or condition of individuals and recruitment are maintained.

7.2. Native Vegetation

7.2.1. Monitoring

Monitoring of vegetation structure, species composition, and fauna habitat features of areas being rehabilitated back to remnant native vegetation will be undertaken using the BioCondition survey methodology (Eyre et al., 2011). The BioCondition survey methodology will enable measurement of the following rehabilitation indicators:

• flora diversity (for each major life-form group or strata)

• stem density (number of large trees)

• tree canopy height

• weed cover

• recruitment of canopy species







• fauna habitat (number and length of fallen logs and percentage litter cover).

Where the rehabilitation involved the re-instatement of an area that is required to remain treeless during project operation, as described in the Remediation, Rehabilitation, Recovery and Monitoring Plan, Q-LNG-01-15-MP-0107 (Australia Pacific LNG 2011a), the assessment will include weed cover, percentage ground cover, and percentage litter cover only. After final rehabilitation of the site, all indicators will be assessed.

Annual BioCondition surveys will be undertaken at the frequency outlined in Section 7.5. Flora diversity can vary during different seasons (i.e. reduced diversity of annuals and perennial herbs during dry periods). As such, BioCondition surveys will not be undertaken during dry periods (late winter-spring, except after a wet winter) and ideally will be undertaken between late summer and mid-winter.

Condition H10 (e) and (f) of the Condabri EA, require that criteria relating to foliage cover and flora species diversity are maintained for at least three years. As such, once criteria are met, monitoring will be required for a minimum of three years. Depending on how long it takes for rehabilitated areas to meet criteria, monitoring may therefore be required for more than five years.

BioConditon surveys will be undertaken by a suitably qualified ecologist.

7.2.2. Photo Monitoring

As part of the annual BioCondition surveys, annual photo monitoring will be undertaken at the centre point of each BioConditon transect, following the methods outlined in Section 5.3.3.

7.2.3. Analogue Site Surveys

Any BioCondition reference sites described in Section 5.3 will continue to be monitored every 5 years or earlier as required using the BioCondition reference site methodology (Eyre et al., 2006). This will enable any changes in vegetation that are not brought about by Project disturbances, such as through drought, to be identified. These surveys will be undertaken at the same time as BioCondition monitoring of rehabilitated sites.

Analogue site surveys will be conducted every 5 years until such time as rehabilitated sites of the same RE meet success criteria for at least three years.

7.2.4. Statistical Analysis

Statistical comparison will involve both the comparison of BioCondition scores and the variables that make up the BioCondition score. The analysis will involve comparison of analogue sites sampled at the same time (outlined in Section 5.3.3).

Comparison of BioCondition scores will involve comparing the rehabilitation site(s) with a minimum of three analogue sites within the same RE using a t-test (a minimum of three sites are required to obtain statistical replication) or similar nonparametric test if a normal data distribution is not obtained.

Testing of all variables that make up a BioCondition score will be undertaken using a multivariate test such as an Analysis of Similarity (ANOSIM) or similar test. This will again involve the comparison of a minimum of three rehabilitated sites within the same RE, with the three analogue sites within the same RE.

To determine whether individual success criteria have been met, variables will be converted to percentages to enable the percentage of each variable to be compared against the mean of the three reference sites. These variables will include:

• flora diversity (for each major life-form group or strata)



• fauna habitat structures (number and length of fallen logs, number of logs with hollows, and percentage litter cover).

All data analyses will be undertaken by a suitably qualified person, as required by Condition A46 of the Condabri EA.





7.3. Pasture To assess the condition of agricultural land, annual Grass Check monitoring of rehabilitated areas will be undertaken. The condition of grazing land will be compared against reference sites adjacent to the disturbance. Grass check monitoring will also be used to assess that adequate grass cover has established on cropping land to prevent erosion. Grass check monitoring will be undertaken on an annual basis with the preference for survey in late summer or autumn (after summer rainfall).

7.4. Soil and Land Capability A final soil and land suitability study will be undertaken after five years to ensure that all agricultural land can be used for its pre-disturbance land use. The results of this survey will be compared to results from the pre-disturbance soil survey outlined in Section 5.3.5, to ensure that soil remains within reasonable parameters. Soil samples taken from agricultural land disturbance areas will be compared to the baseline parameters for soil units found within the Condabri Gas Field Development Area Soil Assessment and Management Plan Q-LNG01-15-MP-0039

Land capability assessment will include a landholder survey of each impacted agricultural properties (grazing and cropping) after five years to ascertain landholder views regarding maintenance requirements are no greater than for surrounding areas.
