Chapter 17 - Hazardous Substances and Facilities Policy 1.2 Promote the rehabilitation of contaminated land with effective site control measures, including monitoring, prior to future redevelopment, change of use, or occupation. There are a number of known contaminated sites in the Marlborough Sounds resulting from past activities involving the use of hazardous substances. The identification and investigation of all contaminated sites is a priority, along with the establishment of a monitoring programme for the more seriously contaminated sites. Contaminated sites need to be managed to avoid adverse effects on the environment. This management is especially important before redevelopment takes place. Any clean up activities need to avoid or mitigate any adverse effects on the environment and be appropriate to the end use of the site. 17.2.6 Methods of Implementation Rules Rules require site management practices which ensure that risks to the environment and community health are avoided, remedied or mitigated. Resource consent for a discretionary activity will be required before any contaminated site is redeveloped, or the use or occupation of the land changes. The Council will require all users of hazardous substances and producers of hazardous wastes to adopt measures aimed at minimising quantities of waste produced and controlling the adverse effects on the environment of discharges and disposal of any such materials (particularly to avoid creating future contaminated sites). Guidelines The Council will promote the use of the Australia and New Zealand Environment and Conservation Council (ANZECC) guidelines for the management of contaminated sites. Information The Council will compile a database of contaminated sites and prioritise them in terms of degree of contamination and associated risk to the environment and community health. Risk assessment procedures for identified contaminated sites will be carried out in conjunction with owners and occupiers and other interested parties. Monitoring The Council will monitor seriously contaminated sites and determine the need for any special rehabilitation and site control measures. The establishment of a database listing and ranking contaminated sites is a prerequisite to the management of those sites. Contaminated sites must be managed and cleaned up in a manner that prevents adverse effects on the environment and community health. Monitoring seriously contaminated sites is a priority for assessing the adverse effects of those sites. 17 - 7
