4 BIOPHYSICAL STRAGTEGIC AGRICULTURAL LAND ASSESSMENT

This BSAL assessment has been conducted in accordance with Interim Protocol. The BSAL status was determined on the dominant soil type within each Soil Unit. The BSAL assessment and limitations for each soil sample site is shown in Table 5.

Only one Soil Unit was identified and mapped with the Study Area, and was verified as non-BSAL due its failure of Criteria 9 (poor soil drainage). There are 108 ha of land verified as non-BSAL within the Study Area based on the soil survey results (Table 12).

Additionally, with 551 ha excluded as BSAL due to greater than 10% slope or being an area less than 20 ha. Therefore the total Study Area has been mapped as non-BSAL (Figure 5).

5 CONCLUSION

This BSAL Assessment for the Mandalong Transmission Line TL24 Relocation Project was undertaken by SLR Consulting. The Study Area for this BSAL Assessment is the entire Project Application Area, plus a 100 m buffer totalled 659 ha and partially mapped as BSAL according to the NSW Government (DP&I, 2012).

In summary the results of this BSAL Assessment are:

• An Exclusion Zone of 519 ha based on land greater than 10% slope was identified and excluded from the soil survey.

• An Exclusion Zone of 32 ha on land less than 20 ha contiguous area was identified and excluded from the soil survey.

• Only one Soil Unit was identified during the soil survey and was considered to be non-BSAL as it failed Criteria 9: Soil Drainage due to poor drainage in the soil profile.

• The two sub-dominant soil types also failed Criteria 9 due to poor subsoil drainage (Chromosol and Sodosol) and Criteria 7 due to moderately poor fertility (Sodosol).

• Eight of the nine sites which underwent laboratory analysis also failed Criteria 12, with either pH in CaCl2 being less than 4.5 and/or having a calcium to magnesium ratio less than 0.1.

Therefore it can be concluded that there is no qualifying BSAL within the Study Area.

Appendix C Soil Salinity Criteria Calculations

The Interim Protocol requires soil salinity to be evaluated using saturated extract data values (ECe). In accordance with Section 7 of the Interim Protocol, ECe can be measured indirectly using EC (1:5) values and applying an approximate ‘conversion factor’ based on soil texture.

The conversion factors for each soil texture are shown in Table A1.
