Appendix 4 – Proposed changes to the activities and planning controls by activity classification Activity classification Land use (residential, rural residential etc) Activity Testing requirements requirements Change from status quo? Permitted Any land use All except disposal of soil (which is controlled) DSI – finds contamination is below soil contaminant standards or Tier 1 soil acceptance criteria Copy of DSI to be provided to council For soil disturbance and fuel tank removals, controls in place to prevent discharges to environment and minimise exposure to people Yes Soil disturbance – small scale None Soil disturbance can be undertaken as a permitted activity without testing up to a volume threshold Yes – minor changes to wording to clarify application Soil disturbance – network utility operators No testing required up but results of testing undertaken during course of works to be provided to council No volume or timeframe limitations A site management plan (SMP) must be prepared and available on site, including: an unexpected discovery protocol sediment and dust control controls for handling and transport of soil, including testing to be carried out to inform disposal description of the condition in which land will be left on completion. Disposal must be to an appropriate location – council must be notified of location, and provided with testing results. Notification to council prior to works. Yes Subdivision and change of use PSI – demonstrates that the activity is highly unlikely to increase risks to health (if Option 2 of proposal 5.3 is adopted) PSI is provided to council etc. See NESCS – no changes proposed. Yes – change test to ‘increase in risk’ Fuel tank removal None See NESCS – no changes proposed. No Soil sampling None See NESCS – no changes proposed. No Soil disposal None Small volumes of soil disposed of to an appropriate location. No – except will sit as a separate activity
Restricted discretionary Residential and rural residential Subdivision, change of use DSI – has that soil contaminants on a site exceeds the applicable soil guideline value for a TOSMP. Matters of discretion will be same as existing restricted discretionary matters. Yes Any Subdivision, change of use DSI – has found soil contaminants that exceed the soil contaminant standards or Tier 1 soil acceptance criteria. Matters of discretion to be same as existing restricted discretionary matters. No Any Fuel tank removal, soil disturbance No DSI provided Matters of discretion linked to effects of the proposed activity, not wider HAIL site. Yes Any Soil disposal No DSI provided Matters of discretion: the approach to managing the soil disposal including soil testing requirements, disposal location, transport method monitoring and reporting of disposal duration of consent timing and nature of review of conditions requirement for and conditions of a financial bond. Yes Discretionary Any Subdivision, change of use None – landowner has chosen not to test their property N/A – council have full discretion – they will determine what the requirements are No (except now only applies to subdivision and change of use).
