Marlborough, including: • background concentrations of PM in Picton are 10 established; • records of agrichemical use allow the cumulative effects of agrichemical use to be established through modelling; and • a monitoring programme to determine the extent of agrichemical spraydrift is established. 15.AER.8 The biological, chemical and physical The values of the following soil parameters for soils state Marlborough’s soils enables safe routinely monitored fall within target ranges, as defined and productive use of the soils on an by Landcare Research (Landcare Research, 2003): ongoing basis. total carbon; • • total nitrogen; • minerisable nitrogen; • soil pH; • Olsen phosphorus; • bulk density; • macro porosity; • aggregate stability; and • trace elements. All potentially contaminated sites recorded on the Listed Land Use Register as at 9 June 2016 are screened for risk within 5 years of the MEP becoming operative. All high risk sites on the Listed Land Use Register identified as a result of screening are investigated. A spill response contingency plan is completed within one year of notification of the MEP. 15 – 49
