Chapter 12 - Rural Environments mounds up to 18 metres high and from there is processed to cleaned bagged product or refined and processed to specific end products. The solar production of salt does have the potential to cause significant environmental effects. In particular, those with the potential to become issues on surrounding rural land include dust, noise, soil contamination and wind borne salt foam. Performance standards will be applied to avoid, remedy or mitigate these adverse effects and on the salt works operation generally. 12.8.2 Objectives and Policies Objective 1 To enable the production of solar salt at Lake Grassmere in a sustainable manner. Policy 1.1 Recognise the national, regional and district significance of the salt works operation. Policy 1.2 Enable the continuation of the salt works operation provided that any adverse effects on the environment are avoided, remedied or mitigated. Policy 1.3 Ensure appropriate measures are in place to avoid the potential for cross boundary effects. Policy 1.4 Encourage the establishment of a Landcare Group comprising residents, iwi, Department of Conservation and the Salt Works Company to manage the boundary area of the Zone. Policy 1.5 Activities in the coastal marine area will be required to meet standards that will maintain the quality of coastal water at Class NS within 1km radius of the coastal water intake existing at 30 May 2002. 12.8.3 Methods of Implementation Zoning The Lake Grassmere Salt Works Zone is identified on the planning maps and includes the Lake itself, an administration, workshop, salt refining and processing area, and a Pipeline Extension Corridor in the coastal marine area. Rules Rules permit the solar production of salt and associated by-produc and the full range of processes required, subject to standards a nd conditions. Rules require resource consents for certain discharges to air, excavation of land, land based aquaculture and activities in the coastal marine area. Resource consents are also required for activities associated with management of salt water intrusion into Cattle Creek and to manage stormwater entering Lake Grassmere. Performance Conditions are included to protect surrounding rural land Conditions uses from excessive noise, soil contamination, dust and wind borne salt foam. 12 - 25 ts
