Comments are as follows:
1. A Bushfire Asset Protection Zone needs to be provided round the pumping station structure, essentially on Penrith Lakes Development Corporation land. Asset protection also needs to be afforded to overhead power supply connections to the pumping station.
2. The river intake and intake pipe are proposed on a currently deep section of the Nepean river. In circumstances at present or in the future where dredging the river is required around or associated with operation of the intake, then a licence would be required from Crown Lands for the dredging works, subject to appropriate environmental assessment.
3. Given the potential erodability of river bank (likely comprised essentially of a fine sand), construction of the intake works, pumping well and access facilities need to ensure that the structural stablility of the river bank is maintained and enhanced as practical in accommodating these works.
4. Noxious aquatic and land-based weeds upstream of and in the vicinity of the intake works need to be eliminated with ongoing monitoring and management provided.
5. Degraded aquatic and terrestrial habitat upstream of and in the vicinity of the intake works needs to be restored as practical, particularly to River-flat Eucalypt Forest in the riparian zone.
6. While treated sewage will likely be benign component of flows pumped into the lakes scheme, a potential consequence in drier times will be the build-up of nutrients in the lakes, possibly contributed to by recreation uses. If nutrient build-up posed a serious problem then this potentially may require flushing of the lakes, possibly at the expense of guaranteed environmental flows in the Nepean-Hawkesbury system.
