THAT monitoring of discharges from Contact Energy Ltd Taranaki combined cycle power plant in the 2006-2007 year continue at the same level as in 2005- 2006. This recommendation was implemented in the 2006-2007 monitoring year. 7.6.5 Alterations to monitoring programmes for 2007-2008 In designing and implementing the monitoring programmes for air/water discharges in the region, the Taranaki Regional Council has taken into account the extent of information made available by previous authorities, its relevance under the Resource Management Act, the obligations of the Act in terms of monitoring emissions/discharges and effects, and subsequently reporting to the regional community, the scope of assessments required at the time of renewal of permits, and the need to maintain a sound understanding of industrial processes within Taranaki emitting to the atmosphere/discharging to the environment.
79 In the case of Contact Energy Ltd, the programme for 2006-2007 was unchanged from that for 2005-2006. It is now proposed that for 2007-2008, a similar level of monitoring is maintained. A recommendation to this effect is attached to this report. 7.6.6 Exercise of optional review of consent There are no consents held by the Company that allow for an optional review of consent in June 2008. 7.7 Recommendations 1. THAT monitoring of discharges from Contact Energy Ltd Taranaki combined cycle power plant in the 2007-2008 year continue at the same level as in 2006- 2007.
