(EP Act) for ERA16 Extractive and screening activities, (1)(a) dredging 1,000t to 10,000t in a year, and
must comply with section 115(1)(c) to (3) of the EP Act as if—
   (a) a reference to the application were a reference to a development application; and
   (b) a reference to the applicant were a reference to an applicant for a development application.

Section 125 (1)(l) of the EP Act requires that the environmental values, associated environmental risks
and the likely magnitude of impacts on the environmental values, management practices to be
implemented to prevent or minimise adverse impacts and a description of the proposed measures for
minimising and managing waste generated by each relevant activity are considered.

It is understood that construction works are expected to take 16 weeks and would require temporary
closure of the area. The dredge footprint is partially located within the resident and migratory shorebird
habitat (sand shoals and intertidal habitat) that are utilised for feeding/ foraging (with roosting occurring in
supratidal habitat around Noosa Spit and the northern banks of the river). Migratory shorebirds are
present from October to April and include a range of nationally and internationally important species.
Further information about the dredge campaign, specifically the potential impacts to high ecological value
waters and shorebird habitat is required.

Response requested:
Please provide:
    1. scaled operational plans showing all relevant places including:
            a. boundaries of the dredging operation, including cross sections with batters and estimated
                or modelled zone of influence of sediment plumes/designated impact zone
            b. the location of the proposed sunken pipeline for transport of dredge material and
                designated disposal sites
            c. a pre-works survey plan that identifies the existing beach profile and cross-sections of the
                proposed nourishment locations relative to tidal environment (HAT and MHWS etc.)
                including the expected post-nourishment beach profile
            d. sensitive receptors and all monitoring locations)
    2. information on potential impacts to the receiving environment, including but not limited to:
            a. turbidity impacts
            b. water quality degradation
            c. potential smothering of benthic communities/ seagrass
    3. a detailed risk assessment for the activity that includes mitigation measures and management
       actions, including a detailed description of the assessment methodology to provide data in
       relation to trigger values that will define alert levels and sediment plume-associated monitoring
       (sampling regime and monitoring sites)
    4. the proposed months when the dredge campaign will be carried out and whether these coincide
       with migratory shorebird seasons. Provide information on why the dredge footprint cannot avoid
       the shorebird habitat and how the activity will minimise/mitigate impacts on the species that utilise
       the habitat.

The following technical guidelines detail the minimum information that should be supplied:
   1. Air: Application requirements for activities with impacts to air
   2. Land: Application requirements for activities with impacts to land
   3. Noise: Application requirements for activities with noise impacts
   4. Water: Application requirements for activities with impacts to water
   5. Waste: Application requirement for activities with waste impacts.
