21 Mr O'Hare, the defendant's Group Engineering Manager, prepared an affidavit. He was notified of the incident at about 8.35pm on 30 January 2006 and attended the premises at about 9.30pm that night. He inspected the break in the pipeline and the clean up and returned the next day for the same purpose. Mr O'Hare observed that the wastewater in the pipeline was not raw effluent, but had been subject to primary treatment removing the majority of solids and fats. The slaughtering ceases at 4.20pm and the boning by 5.00pm. Outside these hours the activities generating wastewater are cattle washing, hygienic wash down and rendering, the majority being generated by cattle washing. Hence, the volume and constituents of the wastewater change significantly after the slaughtering and boning operations cease, with a lower concentration of fat and biochemical oxygen demand. When the ruptured pipeline was discovered, slaughtering and boning operations had ceased. The rupture was located about 40m from the "save all" in a section of pipeline about 1.5m underground. The previous breaks were in an effluent irrigation paddock, which drains to a tailings dam about 400 to 600m from the "save all". After one break in 2001 an internal camera inspection did not reveal any sign that the pipeline would rupture again. The defendant intended to replace the pipeline, but other matters received priority, so the pipeline was scheduled for replacement in mid 2006. The defendant manages capital funds for environmental management on a "highest environmental impact first" basis so issues which may affect the community or are required to achieve compliance receive priority. At the time of the incident, six dams would have operated to receive any effluent from a break in the pipeline except for a 70 metre section between the "save all" overflow basin and the truck access road, which was not protected by a surface water containment structure. The break occurred in that unprotected section. The defendant had been planning to capture all surface water within a first flush system. It submitted a development application for this system on 10 November 2005. That system has now been installed. Had it been in place at 30 January 2006, it would have prevented the wastewater flowing off the premises. These works were completed in October 2006. The defendant has an ongoing commitment to invest in environmental improvement and implementing best practice environmental management. It has also set resource efficiency goals to be met by 2010. Mr O'Hare was not cross-examined.
