3 1. Preliminaries 1.1. Background Coastwide Civil 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. 3 P a g e

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 (SEMP). A discussion of all amber alert events at MP8 and MP9 is included in Section 3.2 Below. Turbidity at MP8 and MP9 regularly exceeded the 5 NTU trigger value, but exceedances were typically minor. The 5 NTU trigger value was exceeded regularly at MP20, however this did not significantly impact upon turbidity levels at near shore points MP8 or MP9. o Turbidity at MP20 typically remained below 20 NTU. There were no significant elevations this month. Turbidity levels are attributable to stormwater flows through site. The northern stormwater channel remained closed to the ocean for the entire month, resulting in the water level at being too low to sample. The lower end of the southern stormwater diversion channel, just upstream of the culvert, was cleaned out in the first week of October. Silt and fine sediment that accumulated in this channel over time, and in particular following the flood event in early June 2016, was removed. 12 P a g e

13 3.2. Real Time Water Monitoring Monitoring Points 24, 25, and 26 Coastwide Civil Test Results Test frequency: Special Method 1 (Using a stationary water quality monitoring buoy that will monitor, record and transmit water quality data at approximately 15 minute intervals) 13 P a g e

14 Coastwide Civil Comments on Results The monitoring buoys were installed in late August and commenced logging data on 17/08/16, three weeks prior to the commencement of ocean based works. The monitors were installed early in order to provide background data prior to the start of works. Ocean based works began on 07/09/16. No legitimate amber or red alerts were triggered due to elevation of turbidity recorded at the monitoring buoys this month. An amber alert was triggered on one occasion at MP8 due to an elevation of turbidity. o 10/10/16 Alert triggered by near shore monitoring at MP8 only. Discolouration appeared to be due to wave action against the excavation at the northern breakwater and placement of rock at the northern breakwater. Turbidity appeared to remain largely localised around the work area. A false alarm amber alert was triggered on 10/10/16 at MP24, the southern monitoring buoy, however this was due to marine fouling. The buoys were cleaned as part of routine maintenance on 12/10/16 and there has been no further fouling issues recorded for the remainder of the month. During this period of fouling, this buoy recorded turbidity of over 200 NTU, despite no visual indications of turbidity. After cleaning, levels immediately returned to typical values. 14 P a g e

35 Page : 2 of 2 Work Order : EW Client : COASTWIDE CIVIL Project : Shell Cove Marina 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. Key : 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. Analysis as per AS 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. Sample exposure period outside AS specifications of 30 +/- 2 days.
