Optional review of consent Not exercised N/A N/A = not applicable During the year, the Company demonstrated a poor level of environmental performance and compliance with the resource consents. During the year under review there were 5 unauthorised incidents, all of which related to air emissions. 1 of the incidents was considered to cause objectionable odours outside the site boundary and had significant effects on neighbouring properties downwind of the plant. This incident resulted in the issuance of an infringement notice, and it is this that has pushed the compliance rating from ‘improvement desirable’ to ‘poor’, and therefore no apparent improvement from the previous few years. What this doesn’t acknowledge however, is the significant improvement achieved on site during the preceding one and a half years. This is best illustrated by the 80% reduction in incidents recorded against the site, when compared with the previous monitoring period. The wastewater treatment ponds continue to perform poorly, and during the monitoring year under review, the discharge from this system has resulted in raised levels of BOD5 and nutrients in the Kahouri Stream. These changes in water quality are likely to have been the primary factor in the changes recorded in the biological survey. This survey found a significant decrease in MCI and SQMCIS scores downstream of the confluence with the abattoir tributary. This is likely to be due to the impacts from the abattoir (rather than the Ballance Agri Nutrients site), but this is unclear without further monitoring. Therefore it is recommended that additional sites be included in subsequent surveys to assess the impact of the abattoir discharge on this unnamed tributary. Nevertheless, it is also suggested that the consent holder continues further investigations into improving this treatment system to ensure the wastewater is treated effectively. The new consent 6570 to bury raw degenerating material to land in emergency situations requires a waste burial management plan to be submitted to the Council by June 2005 (special condition 5). Although there are details of the requirements of this consent in the contingency plan provided by the Company, this does not address all the matters defined in special condition 5 of consent 6570. The contingency plan should be reviewed to include all requirements of the Waste Burial Management Plan. 2.6.4 Recommendations from the 2005-2006 Annual Report In the 2005-2006 Annual Report, it was recommended:
