4 The maximum penalty applicable to offences under s 64(1) of the POEO Act is $1 million for a corporation. The penalty for this offence was increased to $1 million from $250,000 in May 2006.
Background
5 The parties agreed a Statement of Agreed Facts (SOAF) which provides as follows:
Background
…
5) Forgacs operates a floating dry dock facility ('floating dock') at its premises located at 81 Denison Street, Carrington ('the Premises') for the purpose of carrying out maintenance work on ships.
6) The Premises are located on the eastern side of the Throsby Basin within the Port of Newcastle, in the Newcastle Local Government Area.
7) The principal business carried out at the Premises operated by Forgacs is ship repair, and this involves docking ships, and the associated blasting (including abrasive grit blasting), painting, structural repairs, electrical and some mechanical repairs. All the major repair work is carried out within the floating dock itself on both commercial ships and ships of the Royal Australian Navy.
8) The floating dock is a vessel itself. Raising and lowering the dock involves using the harbour's salt water. To sink the dock, valves are opened to sink the dock in a controlled fashion. The ship to be repaired then moves into the dock. The dock and ship are then raised by pumping the salt water out of the dock tanks and into the harbour.
9) The vessel in the floating dock at the time of the incident was the "Searoad Mersey", which was a commercially owned vessel trading in Australian waters. The scope of work included abrasive grit blasting and spray painting of the external hull. There was some structural repair work inside, some minor electrical repair and some mechanical repair work.
10) Abrasive grit blasting is a process undertaken to remove the paint which coats the hulls of vessels and involves air blasting the hull of a vessel with an abrasive medium such as copper slag.
11) The marine paint removed through the abrasive grit blasting process can sometimes contain "anti-fouling" components such as Tributyltin ('TBT') which are included in the paint to prevent the build up of marine organisms on the hulls of vessels.
12) TBT is a very highly toxic chemical which has both acute and chronic effects on marine organisms at very low microgram per litre levels. TBT bioaccumulates in tissues of many organisms, especially molluscs and it is particularly detrimental to marine organisms such as oysters and mussels, resulting in shell deformities, reduced growth and mortality of juveniles. It also severely affects marine snails (gastropods) causing "imposex" which is when female snails develop male characteristics, leading to a lack of reproductive capacity. These toxic effects resulted in an International Maritime Organisation ban on the use of TBT on vessels which became effective in 2008.
13) Although the use of TBT has been banned, it can enter the environment when the hulls of ships, treated prior to the international ban, are blasted through the abrasive grit blasting process described above in paragraph 10. TBT can be leached from paint flakes if the material falls onto water surfaces and, because the flakes have a high surface area, the leaching rate will be greater than when the paint was as coating on the hull.
Background to incident
16) In recent years the Department of Environment and Climate Change ('DECC') has received a number of complaints regarding particulate emissions and painting overspray from activities carried out on the floating dock at the Premises.
17) On 29 October 2001 DECC issued a Notice of Variation of Licence that included PRP Condition U1 (Paint and Abrasive Material Drift) that required Forgacs to implement works outlined in the report titled "Prevention of Paint and Abrasive Blast Material Drift from the Floating Dock Muloobinba Report" dated 9 March 2001('the Report'). The works outlined in the Report required Forgacs to make improvements to the encapsulation system, which was not considered satisfactory. The required work was carried out by Forgacs.
18) On 26 February 2003 DECC issued a penalty notice to Forgacs for breaching Licence Condition O6.1 on 5 January 2003. In this instance, several boats moored at Newcastle Cruising Yacht Club ('NCYC'), 91 Hannell Street, Wickham, were affected by particulate matter originating from abrasive grit blasting activities conducted at the floating dock.
19) On 28 November 2003 DECC issued a Notice of Variation of Licence that included the removal of PRP Condition U1 as the required works had been carried out.
20) On 29 December 2003, DECC's Environment Line received 2 reports of excessive dust levels coming from sandblasting a ship in the dry dock at the Premises. At NCYC, a number of boats moored at NCYC and surrounding waters were affected by the particulate emission originating from the Premises. On 29 March 2004 DECC issued a penalty notice in response to this incident for breaching Licence Condition O6.1.
21) Consistently with Forgacs' obligations under the Licence, the Premises have a range of environmental control measures to control any dust emissions from grit blasting. The gap between the vessel and the floating dock is encapsulated with a shade cloth type material. Such encapsulation has been the practice at the Premises for a number of years. The encapsulating material was in place prior to the Incident involving the Searoad Mersey occurring and is referred to variously in the evidence as "shade cloth", "green shade cloth", "shrouding", "shade cloth shroud" and "green shade-cloth cover" ("shade cloth shroud").
Events of 30 December 2007
22) On 30 December 2007 at about 7.30am, Paul Booth, Dock Manager at NCYC, conducted an inspection of berths and vessels at the NCYC marina.
23) NCYC operates a marina adjacent to the Premises, and is located on the western side of the Throsby Basin within the Port of Newcastle. A map which shows the location of NCYC and its proximity to the floating dock at the Premises is included at Tab 2 in the Tender Bundle.
24) During his inspection of the NCYC marina Mr Booth observed a black brown coloured grit substance deposited on most of the vessels in the marina including his own boat which was moored at Finger wharf "B". He hosed down his boat to remove the grit substance. During the day he also received a number of complaints from other boat owners advising of deposits on their boats.
25) After being advised by Mr Booth that boats in the marina and marina walkways were covered with fine black grit, on 30 December 2008 Mr Ernest Keegan, Club Captain and Company Secretary of NCYC, drove to NCYC at approximately 9.00am to inspect the boats and marina.
26) Mr Keegan observed that the whole marina complex, including marina fingers, shore-based buildings and boats moored at the marina were covered with a black dust. He could see that there was a ship in the floating dock at the Premises and heard the sound of grit blasting machinery operating. He observed that there were gaps in the shade cloth shroud covering the ship in the floating dock and could see fine particles being emitted from the floating dock at the Premises and being driven across the water towards NCYC by wind.
27) Later that day Mr Keegan phoned Forgacs to report the incident and lodge a formal complaint.
28) Also on 30 December 2007 DECC's Environment Line received a report (Reference No. 104013) from a representative of NCYC advising that Forgacs was abrasive grit blasting a ship and that residue from the activity had escaped, contaminating the water and boats moored at the NCYC's finger wharves. A copy of the Environment Line report No.104013 is included at Tab 3 in the Tender Bundle.
29) DECC Officer Hamish Rutherford received details of the Environment Line report and at approximately 7.15pm he attended the NCYC premises.
30) From the NCYC premises Mr Rutherford saw a vessel docked in the floating dock, most of which was shrouded in a green shade cloth shroud. He did not see any work being carried out at the floating dock and left the premises as a result of the fading light.
Events of 31 December 2007
31) On 31 December 2007 DECC's Environment Line received another seven pollution incident reports alleging that dust emissions blown across the harbour from the floating dock were impacting vessels moored at the NCYC marina. Copies of these reports are included at Tab 4 in the Tender Bundle.
32) These pollution incident reports were referred to DECC's Newcastle Office for investigation.
33) On 31 December 2007 at approximately 10.30am, DECC Officer Grahame Clarke arrived at the NCYC marina. Mr Clarke observed a heavy coating of particulate matter on the decking, cabin and rigging of various vessels moored at berth "C". He proceeded to collect samples from a vessel named 'Plastic Toy' berthed at mooring C17 and a vessel named 'Funnel Web' berthed at mooring C27. The granular material sampled from the surfaces of the boats was black, fine grained and gritty to touch.
34) Photographs were taken of the surfaces before the dust sample was collected. Some of these photographs are included at Tab 5 in the Tender Bundle.
35) Mr Clarke observed and took samples of a floating red/black slick on the surface of the water around finger wharf "C" and elsewhere at the marina. The slick extended from the western side of the floating dock at the Premises to the NCYC marina. Sample analysis indicates that the solid material in the water contained high levels of tin and titanium which is consistent with paint material containing tin. Analysis also showed levels (greater than) > 5000ng Sn/g for each of TBT and its break down products, Dibutyltin ('DBT') and Monobutyltin ('MBT') in the solid material, consistent with the presence of antifouling paint. Analysis of the liquid component of the slick sample indicated that the material contained 23,000 ng/L of TBT 27,000 ng/L of DBT and 860 ng/L of MBT.
36) Mr Clarke took several photos of the material he observed floating on the surface of the water in the marina which are included at Tab 6 in the Tender Bundle.
37) While standing on finger wharf "C" Mr Clarke could see clearly that particulate matter was escaping from a green shade cloth shroud fixed over a vessel docked in the floating dock at the Premises. The prevailing light breeze was blowing the visible particulate matter from the mid section of the floating dock at the Premises towards the marina. Activities identifiable as abrasive grit blasting were clearly audible at this location above the low background noise at the NCYC marina.
38) Mr Clarke contacted a representative of Forgacs at approximately 12.00pm to arrange to inspect the floating dock. He left NCYC shortly thereafter.
39) At approximately 12.15pm Mr Clarke inspected the floating dock at the Premises in the company of two Forgacs representatives, Ms Sarah Neil and Mr Michael Sweeney. At this time, no abrasive grit blasting or other works were taking place. Ms Neil advised that work had stopped at approximately 12.00pm and was not due to commence until the following day.
40) Upon inspecting the shade cloth shroud covering the 'Searoad Mersey', the boat docked in the floating dock, Mr Clarke noted the shade cloth shroud covering the vessel was not contiguous for the length of the vessel and there were substantial gaps through which particulate matter could escape the shade cloth shroud. Ms Neil acknowledged that there were gaps in the shade cloth shroud. He also observed that there was a heavy layer of gritty black material along the upper deck of the floating dock. Mr Clarke sampled this material using a new paintbrush and glass sample jar.
41) Mr Clarke noted the similarity in appearance and touch of this material to the material he had sampled on the two vessels at the NCYC marina. Ms Neil advised Mr Clarke that Forgacs were using copper slag material to grit blast paint from the vessel.
42) Before leaving the Premises, Mr Clarke instructed Forgacs to submit a written report, within 14 days, to DECC in accordance with condition R3.1 of the Licence.
3 January 2008 DECC inspection of NCYC and Premises
43) On 3 January 2008 a team of DECC officers including Hamish Rutherford, Christy Groves, Sian Harris and Peter Hughes, attended NCYC to collect samples of particulate matter from the decks of vessels moored at the NCYC finger wharves.
44) Vessels moored along the various NCYC finger wharves were visually inspected for the deposition of particulate matter on their exterior. Varying amounts of particulate matter were observed on the exterior of the majority of vessels moored at the time of the inspection.
45) The officers observed that the particulate matter on the vessels was black. The quantity of particulate matter deposited on a particular vessel varied depending on where it was moored. In general, the deposition of particulate matter appeared to be more concentrated on boats moored along finger wharves "C", "D" and "E" and increased from west to east along the finger wharves as the proximity to the floating dock at the Premises increased. The map included at Tab 2 of the Tender Bundle shows the relative proximity of the floating dock to NCYC. NCYC is denoted on the map by the yellow shaded area labelled "Marina Yacht Club" and the floating dock is denoted on the map by the yellow shaded area labelled "Floating Dock".
46) Where possible, samples were collected from each vessel that was observed to have a deposition of particulate matter on the exterior decking. Particulate samples were collected from the decks of a total of 48 vessels moored at NCYC. The samples were collected by using a paint brush to sweep particulate matter from the vessel's deck into a sample container. Photographs were taken of each vessel moored at the marina at the time of the inspection. Some of these photographs are included at Tab 7 in the Tender Bundle.
47) Following the sampling procedure at NCYC, Mr Rutherford, Ms Groves and Ms Harris attended the Premises. At the time of the inspection the vessel 'Searoad Mersey' was still docked in the floating dock and was enclosed in a shade cloth shroud, with the dock raised out of the water. There were four abrasive blasting crews in operation. Samples were collected of the spent grit blasting material which was deposited on the floor of the dock underneath the vessel and from the upper dock on the external side of the shade cloth shroud.
48) Analysis results have confirmed that the particulate matter collected from the decks of the vessels moored at NCYC (samples #200800559 - 570) had a high degree of similarity with material collected from Forgacs (samples #200800571-574). Both groups of samples contained high levels of TBT (greater than 5000 ng/g) which is consistent with the presence of antifouling paint.
49) Whilst standing on the edge of the dock on its upper level, it was observed that particulate emissions of fine grit blasting material were passing through the shade cloth shroud and escaping into the atmosphere and away from the Premises. As a result of these emissions Ms Groves, Ms Harris and Mr Rutherford became covered in fine grit blast material. Photographs were taken of the Premises during the inspection and some of these are included at Tab 8 in the Tender Bundle.
50) On 3 January 2008 Mr Alan Evans, a representative of Forgacs, contacted Mr Clarke by telephone and advised him that Forgacs had installed a second layer of shade cloth and would station observers with water sprays on the upper deck of the floating dock to hose down any particulate matter escaping the shade cloth shroud. Mr Evans advised that if these measures were unsuccessful Forgacs would suspend abrasive grit blasting operations until weather conditions were more favourable to preventing dust from the floating dock escaping the Premises.
51) After the Incident, Forgacs liaised with NCYC and had officers attend the NCYC wharf. On or around 5 January 2008, Forgacs provided a work team to NCYC to clean up the grit blast material deposited on the marina walkways and the vessels moored at the marina. Over the following days Forgacs staff cleaned the affected vessels and the finger wharves of the NCYC marina. NCYC wrote to Forgacs to say that the clean up had been carried out to their satisfaction.
52) On 29 January 2008 Forgacs sent DECC an incident report in relation to particulate emissions from the Premises occurring on 31 December 2007. A copy of the incident report is included at Tab 9 in the Tender Bundle. In the incident report Forgacs explained:
· "During a routine grit blasting activity on the floating dock grit blast medium escaped from the environmental encapsulation erected over a vessel which was at the floating dock";
· The particles escaped the Premises because "the blasting of one area of the vessel intensified the concentration of grit blast medium in that area and fine dust particles passed through the encapsulation and were blown towards the marina by the wind";
· Upon notification by DECC, Forgacs took immediate action to prevent further escape of particulate emissions from the Premises; and
· Long term actions to ensure effective encapsulation of dust particles.
53) On 4 June 2008 DECC conducted a recorded interview with Mr Stephen Morley, Operations Manager at Forgacs.
54) During that interview Mr Morley:
· Stated that the name of the vessel in the floating dock at the time of the Incident was named the 'Searoad Mersey';
· Admitted that the paint on the 'Searoad Mersey' contained TBT;
· Admitted that Forgacs does not test the paint of vessels to determine if the paint contains TBT;
· Acknowledged that the blast medium used by Forgacs is a copper slag product; and
· Admitted that the encapsulation in place at the time of the Incident did not cater for the finer particles escaping through and that resulted in the outfall.
55) Also on 4 June 2008 DECC conducted a recorded interview with Mr Michael Sweeney, Dockyard Operations Manager at Forgacs.
56) During that interview Mr Sweeney:
· Admitted that at the time of the Incident there were holes in the shade cloth shrouding the 'Searoad Mersey'; and
· Outlined the procedures undertaken by Forgacs to prevent the further escape of particulate matter from the Premises.
