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. 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 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

The 5 NTU trigger value was exceeded at MP7, MP8 and MP12 on a number of occasions. o Severe storm conditions were observed on a number of occasions during this month.

Peaks in recorded turbidity align with the most severe weather events. Recorded rainfall is presented in Section 3.2 below and complete records attached at Appendix C.

o During storm events, turbid water was generated upstream of the site and flowed through site stormwater channels into the ocean. Inbound water quality results are presented in Section 3.2 below.

o Rough seas were observed over a number of days during storm events. This further impacted turbidity levels.

o Site impacts on water quality were minimal. Site environmental controls performed well during the storm events. Dirty water within the site storage pond, open excavations and other construction areas did not breech into the site clean water system. Some damage to site controls such as silt fences was observed and has been repaired as soon as possible.

Water quality in the beach zone rectangular pond has been consistently good and water level stable at around RL 1.0m.

o There was an elevation of turbidity recorded on 26/08/14 and 27/08/14. It was observed that some coastal waters were entering the pond from the south-east due to rough seas. This water was contained within the pond and turbidity settled over the following days. There was no breach of the constructed sand wall along the eastern edge of the pond.

Comments on Results

Discharge of the main storage pond: o Commenced 11/08/14 and ended 15/08/14 o Commenced 19/08/14 and is ongoing.

Swamp entrance: o Was mechanically opened on 11/08/14 and 13/08/14. o Opened naturally on 18/08/14 due to heavy water flows from upstream during storm

conditions and remained open as of the end of the month.

Notable Rainfall Events: o 11mm rainfall recorded 13/08/14 o Total of 136.5mm recorded from 18/08/14 – 22/08/14:

(18/08/14 – 85mm, being rainfall over the weekend, 19/08/14 – 42mm, 20/08/14 – 4mm, 21/08/14 – 1mm, 22/08/14 – 4.5mm)

o Total of 97mm recorded from 25/08/14 – 29/08/14: (25/08/14 – 21mm, being rainfall over the weekend, 26/08/14 – 12mm, 27/08/14 – 52mm, 28/08/14 – 9.5mm, 29/08/14 – 2.5mm)

High turbidity was recorded in inbound streams during heavy rainfall events. The most significant source of these flows was at Monitoring Point 10, measuring water inbound from west of the site. A significant volume of inbound water was observed at MP10 during rainfall events.

Turbid inbound flows were observed coming from the Stage 10D2 Subdivision site during these rainfall events. A sample of this water taken on 26/08/14, at the point where it enters the project site, showed a turbidity of 544 NTU.

*Tests undertaken on site by Coastwide Civil Remarks

Discharge commenced on 11/08/14 and ended 15/08/14. o All monitoring results are compliant with discharge criteria. o The water sample taken on 18/08/14 had high turbidity, indicating that total suspended

solids were likely to exceed the EPA discharge criteria. As a result, discharge was not permitted on that day. This decision was justified following the receipt of lab results.

Discharge commenced 19/08/14 and is ongoing. o On 28/08/14, total suspended solids exceeded the 50 mg/L discharge criteria. Discharge was

permitted on the day due to a recorded turbidity of 33.60 NTU. Using site correlation data, it was not expected that total suspended solids would exceed 50 mg/L. Turbidity/TSS levels in the storage pond had lowered significantly by the next day.

Comments on Results

At MP17, weekly LAeq exceeded the trigger value in the first week of the month.

At MP18, weekly LAeq exceeded the trigger value in the first and second weeks of the month.

At MP19, weekly LAeq did not exceed the trigger value.

Consultation with the community about the project has been ongoing. A community newsletter is being distributed monthly, explaining current works on site. A signboard has been erected at the site entrance providing a general explanation of the project. Both the newsletter and signboard contain contact information to allow any residents to communicate concerns about noise levels.

No complaints have been received in this month about noise levels.

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 sampling time information is not provided by the client, sampling dates are shown without a time component. In these instances, the time component has been assumed by the laboratory for processing purposes.

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

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.
