1. Preliminaries 1.1. Background

This project involves the construction of a boat harbour consisting of inner and outer harbour basins located behind an existing beach dune system in what is currently a degraded swamp, and an access channel across the beach. Included in the boat harbour project are:

• inner and outer harbour basins; • boardwalk/promenade surrounding the inner and outer harbours; • regional boat launching ramp located in the outer harbour; • 470m long rock breakwater on the northern side of the access channel; • 282m long rock groyne on the southern side of the access channel; • dune construction and beach nourishment; • land platform works for hotel, shopping centre, residential development, marina support facilities

and dry boat storage surrounding the boat harbour; • a staged 300 berth floating marina in the inner harbour; • vessel fuelling facilities and sewage pump out facilities in the outer harbour; and • a boat lift and hardstand area for vessel maintenance.

The works are to be conducted over multiple stages. Coastwide Civil have won the contract to conduct Stage 2 works. In addition, Coastwide Civil have also won the contract to construct the breakwaters for the boatharbour. The environmental management plan and practices in place for the Stage 2 project have broadened to also cover the breakwater works. The main components of Stage 2 works are:

Excavation of the remainder of the Boatharbour which was not excavated in Stage 1

Surcharging (and removal) of the P2B Surcharge Area and any incomplete portions of the P3 Surcharge Area

Removal of the surcharge material from Surcharge P1A, P1B and P2A

Construct edge treatment for the Boatharbour

Install boardwalk piles

Construct boat ramp in the Outer Harbour The main components of the Breakwater works are:

the construction of a 470m long breakwater north of the channel

280m groyne (smaller breakwater) south of the channel

full excavation of the entrance channel

Installation of navigation aids (navigation lights and buoys)

Construction of permanent access roads along the breakwater and groyne

1.2. Introduction

This document provides a summary of monthly environmental performance on site. It includes the following:

Section 2 outlines monitoring requirements as per the conditions of the Environmental Protection Licence (EPL), the Site Environmental Management Plan (SEMP) and the Construction Environmental Management Plan (CEMP);

Sections 3 to 5 detail the results of environmental monitoring undertaken on site; and

Results of any lab testing are included as Appendix B. A copy of rainfall monitoring results for the month is attached as Appendix C.

Comments on Results

Since the commencement of breakwater construction in the ocean on 07/09/16, a red and amber alert system has been implemented. As part of this system, an exceedance of 15 NTU at MP8 or MP9 triggers an amber alert, as detailed in Section 11.4 of the Site Environmental Management Plan.

Amber alerts were triggered on thirteen days in this month at MP8 or MP9. o Investigation showed these were due to stormwater flows through site, not as a result of

breakwater works. During construction works, a localised plume is often visible at the face of works on the breakwater; however this does not extend to monitoring points MP8 or MP9. As the plume is generated by agitated sand, the discolouration drops out of the water quite quickly.

o Amber alerts are more commonly triggered at the southern ocean point, MP8, rather than the northern point, MP9. This shows that the construction of the breakwater has had a positive effect in protecting the bathing area of the beach from the impact of stormwater flows through site.

While turbidity at MP8 and MP9 regularly exceeded the 5 NTU trigger value, exceedances were typically minor. The maximum recorded turbidity at either point was 36.28 NTU, despite ongoing rainfall throughout the month.

The 5 NTU trigger value was exceeded regularly at MP20. o Turbidity at MP20 remained below 30 NTU on approximately half of all readings this

month, but was often elevated during and after rainfall. o With rainfall recorded on 18 out of 23 workdays, stormwater flows through site were

significant and resulted in turbid flows through MP20. Turbidity peaked at 80 NTU on 17/03/17; a day where 107.0mm rainfall was recorded on site.

o Ongoing wet conditions throughout February and March have meant the site has not had a chance to thoroughly dry out. The effect of smaller amounts of rainfall has been exacerbated as a result, as the ground has less capacity to soak up water.

The northern stormwater channel remained closed to the ocean for the entire month, except on the four days listed in the table above. On these occasions, the northern channel was mechanically opened in preparation for expected heavy rainfall and the resulting stormwater flows. Turbidity was measured at 87 NTU on 17/03/17 at this point, but was otherwise low.

Comments on Results

Northern channel opening (MP12): o Was closed for most of the month, except for four days where the channel was mechanically

opened. These dates are noted in Section 3.1. The opening was conducted prior to heavy rainfall, to mitigate against flooding risk upstream.

Southern channel opening (MP20): o Channel remained open naturally for the entire month.

Inbound streams: o MP10 was flowing for the majority of the month. Turbidity was typically low, but spiked

during days of high rainfall. Turbidity peaked at 89 NTU on 17/03/17. o MP11 was observed to be flowing on two occasions. Turbidity was elevated on both dates. o MP14 flowed on five occasions, during periods of high rainfall. Turbidity was high on each

occasion. o MP21 was flowing on eleven occasions. Turbidity was high on days of heavy rainfall. This is

attributable to runoff from upstream subdivision and house construction sites, which currently appear to be the primary source of turbid runoff reaching the clean water system. During drier weather, there is typically a small trickle of water present, which is of too low volume to sample.

Notable Rainfall Events: o 11.0mm recorded on 11/03/17 o 30.0mm recorded on 03/03/17 o 22.0mm recorded on 06/03/17 o 11.0mm recorded 15/03/17 o 106.0mm recorded 17/03/17 o 24.0mm recorded 20/03/17 o 18.0mm recorded 23/03/17 o 23.0mm recorded on 31/03/17 o Rainfall has been recorded on site on 18 out of 23 weekdays this month for a total of

304.0mm rainfall. o 11 other occasions of <10.0mm rainfall recorded, full rainfall records included in Appendix C

Some data from February was not received in time for inclusion with the February report and has been presented above.

Remarks – MP23

On 01/03/17, a sample leaked during transport to the lab and was unable to be analysed. Turbidity results indicated that TSS levels would be below the discharge criteria. pH levels were within the EPA discharge criteria.

Discharge was undertaken on the above listed days. All site based monitoring and received lab testing results are compliant with discharge criteria

General Comments

The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house

developed procedures are employed in the absence of documented standards or by client request.

Where moisture determination has been performed, results are reported on a dry weight basis.

Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis.

Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

When no sampling time is provided, the sampling time will default 00:00 on the date of sampling. If no sampling date is provided, the sampling date will be assumed by the laboratory and displayed in brackets without a

time component.

Where a result is required to meet compliance limits the associated uncertainty must be considered. Refer to the ALS Contact for details.

CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.

LOR = Limit of reporting

^ = This result is computed from individual analyte detections at or above the level of reporting

ø = ALS is not NATA accredited for these tests.

~ = Indicates an estimated value.

Key :

Analysis as per AS3580.10.1-2003. Samples passed through a 1mm sieve prior to analysis. NATA accreditation does not apply for results reported in g/m².mth as sampling data was provided by the client.l

Sample exposure period is 27 days which is outside the typical exposure period of 30 +/- 2 days as per AS3580.10.1.l
