CSR's response and the defence case
28 In the 2007 annual report, CSR Limited's Chairman points to the Group's commitment to sustainability, and its "SHE" ("Safety, Health and Environment") management programme, which is said to have commenced in the 1980's. In the year ended 31 March 2007 there was an overall fall (15.8%) in environmental incidents, compared with 2006. Level 1 is "minor", Level 2 "significant", and Level 3 "serious". There were no Level 3 incidents reported in respect of either year. There was a drop in Level 1, but a slight increase in Level 2 in the year ended 31 March 2007.
29 In his affidavit (par 47) Mr Juno has a 4th level of incident at the top of the scale, Level 4 "severe". Before this prosecution commenced (after the reporting period ending 31 March 2007) the subject spill was classified Level 1, but Mr Juno says it has since been upgraded to Level 3. In his oral evidence he could not tell the Court when and by whom that "upgrade" was made, nor when the estimate of the volume spilt was increased to the now agreed amount (T22 L8-20).
30 The annual report (at p21ff) outlines a programme of changing to water-based coating of cement roof tiles - at p23 CSR Limited states its expectation that water-based coating would be in place, instead of GEP2 coating, at all concrete roof tile plants by March 2008, but the evidence indicates delays, which the EPA apparently accepts, as its April 2008 licence renewal allows a further three years for the conversion.
31 Ms Birch was recruited from outside CSR on 11 July 2005 as part of the company's programme to "reinvigorate their environmental performance". Her remit was to drive change in this largely autonomous role and align that change with the commercial imperatives of the company. In her affidavit she deals at some length with the evolution and administration of SHE and annexes the SHE management system document dated December 2003 (running to 134 pages). She reports to the Executive General Manager, who reports to the Managing Director of CSR. She was consulted by Ian Stott and attended the Rosehill site on Monday 17 July. She took part in the decision that the spill should be reported to the EPA by Stott. The SAF also records (par 109) the appointment in February 2007 of a Mr Peter Truasheim as National Environment Manager, CSR Bricks and Roofing.
32 Neill Evans had been Executive General Manager of the CSR roofing business since 2002. It amalgamated with the bricks business in November 2006. He reports directly to the Managing Director of CSR. The company has 14 operational manufacturing sites in Australia and New Zealand, four of them in New South Wales. He says he is "deeply upset and concerned that this incident occurred", and (in his affidavit sworn on 28 May 2008) he says that the Rosehill operation will be converted to water-based "within 18 months". Mr Evans did his best (at T26 LL17-35) to explain away the delay in making the conversion. He undertook (T28 LL4-11) that the information in the 2007 annual report regarding the incident, its classification, and the conversion, will be updated in the 2008 report. On the question of remorse he said (at T27 LL15-25):
" I think everyone at CSR takes their safety and environmental obligations and responsibilities very seriously. It is one of the core values of CSR that we look after employees and the environment, and for our systems and our training to have broken down we take that very seriously. I've had a significant number of conversations with our Managing Director, with the Chairman of the Board, with other Board members on this topic, and all are deeply disappointed that whatever we have done is not enough to have prevented this from occurring."
33 Mr Juno sets the procedures for his subsidiary in line with the parent company's corporate guidelines. He confirmed that there was not enough senior level consultation before the decision was taken to change the connections on the Friday evening. He also conceded that his earlier decision to authorise the temporary arrangement reflected a primary concern to allow production of concrete tiles to continue. He admitted that he made the ultimate decision to place the Schultz container outside the bunded area, and that the hoses were too short, but he opined that it represented the least risky way to empty the Palecon tank. He admitted not considering the risk of a spill (see his affidavit pars 24-26). He put in the "near miss" report dated 17 July (SAF par 112, Exhibit P2 tab 1).
34 In par 54 of Mr Juno's affidavit there appears the following list of actions taken by CSR "to ensure a similar event does not occur again" (see also SAF pars 106, 108-111):
"(a) The bunded area was expanded in November 2007 at a cost of approximately $30,000 so that other items could be stored in it.
(b) We are working on ceasing the use of GEP as a coating for our roof tiles. A water based, rather than solvent based, replacement is currently being investigated and developed. While this decision was based on a number of factors, the potential harm to the environment from the use of GEP was one of the main reason (sic) to discontinue its use. As a CSR (sic) will replace plant and equipment at a cost over $1 million.
(c) I conducted a Toolbox Talk about the incident, what corrective actions were taken and how to avoid this type of incident in the future. Toolbox Talks have also been formalised and now have a set agenda and recorded attendance.
(d) External consultants were hired to provide further spill response training for all employees. In addition, we hire external environmental training consultants regularly and our site specific training register ensures every employees training is up to date. This costs approximately $20,000 per annum.
(e) I now conduct monthly work place audits on parts of the Rosehill Site which includes an environmental component. …
(f) We realised as a result of this incident that along with training, the maintenance and testing of our equipment and procedures required attention. Accordingly, a maintenance register is now in effect….
(g) During the interim period while we investigate a replacement product for GEP, we have implemented a procedure whereby the stormwater system gates (which prevent any stormwater from leaving the site) are to be closed during all deliveries of GEP to ensure that, should any spill occur, it cannot leave the premises."
35 Ms Schroeder's affidavit deals with actions taken following the service of the EPA's evidence on 29 June 2007. On 18 September 2007 the inventor of GEP2, Mr David McKay, provided CSR with a preliminary report denying that the product removed from the Parramatta River was, in fact, GEP2. She says (par 11) "this finding support CSR's genuine belief that it was not responsible for the spill that occurred in the Parramatta River". However, on or about 20 December 2007, Dr Rivett and Mr McKay expressed the revised opinion that the material in the Parramatta River was "a probable match with GEP2". There was then a delay over Christmas before the company's officers could consult the Board on the plea to be entered in this prosecution. The Board did not meet to consider the position until 11 February 2008, and she personally gave instructions to the lawyers in the week of 10 March to plead guilty (SAF pars 126-129).
Consideration
36 The Prosecutor accepts that the spill was accidental, but submits that the evidence shows that the accident was caused by a "fundamental system failure", compounded by human error. A seriously inadequate temporary system of operation was adopted, to ensure continued production, without any (or any adequate) consideration being given to the possibility of a spill occurring outside the bunded area. An employee then failed to complete, in a safe way, the reversion of the production process to its normal state. A spill was foreseeable, even if not considered likely, and no precautions (such as temporary bunding) were put in place.
37 The Prosecutor also accepts that the Defendant developed and maintained an honest belief that only a relatively small amount of pollutant was spilt (a maximum of 365 litres - SAF par 43). However, a spill having occurred, the Defendant's licence required it to notify the EPA "as soon as practicable", by phone to the EPA's Pollution Line, and, then, in writing within 7 days (Licence condition R2 - see Exhibit P2 tab 5 p20). The on-site spill occurred overnight on 14-15 July, and relevant senior managers were notified by/at about 8am on 15 July, but no report was made to the EPA until about noon on Monday 17 July.
38 A more timely notification of the on-site spill, regardless of any corporate ignorance of the condition of the river prior to the TV news on the Sunday night, almost certainly would have assisted the authorities in investigating, tracing, and dealing with the pollution incident in the river.
39 Section 241 of the POEO Act lists a series of factors to be taken into account in sentencing for an offence under that Act, and other relevant considerations are prescribed (with some overlap) by the Crimes (Sentencing Procedure) Act 1999 ("CSP Act"), especially sections 3A, 21A, 22 and 23.
Environmental Harm
40 As noted above, there is substantial agreement between the Prosecutor and the defence regarding the potential and actual harm (see par [12] and SAF pars 90-99). Such harm is a relevant factor under s.241(1)(a) of the POEO Act, and an aggravating factor under s.21A(2)(g) of the CSP Act. See Environment Protection Authority v Waste Recycling and Processing Corp (2006) 148 LGERA 299. There was actual harm occasioned to the riverside mangroves and the habitats of invertebrates, albeit that there were no signs of dead or dying mangroves or biota (SAF pars 90 and 92). It is also agreed that it is likely, even very likely, that other harm occurred (see SAF pars 91, 92, 96, 97, 98).
41 For present purposes the following statements (from SAF 98-99) summarise the position to be weighed in arriving at sentence:
" 98. The spill of between 2,250 to 3,250 litres of GEP2 on Saturday, 15 July 2006, caused a change in the chemical composition of waters in a localised area in Parramatta River. The tides and environmental conditions in the River on Saturday, 15 July 2006 had very likely caused the split GEP2 to seriously impact on parts of the inter-tidal mangrove swamp, for example the crabs in the sediment holes, during the initial stage of the spill. This adversely affected sediment-dwelling organisms in the mangrove by physically trapping and/or smothering them. The affected organisms would have had difficulty recovering from the direct contact with they hydrocarbon solvent component of GEP2. The environmental conditions during the incident would have facilitated the weathering of GEP2 in the River that continued until Monday, 17 July 2006. The weathering of GEP2 left residues described as 'white gluey material' floating on water and hanging like 'thick spider web' on mangrove root system. Further, there may also have been components that dissolved into the water column….
