(1-2) These questions relate to the Water Resources Management Plan (WRMP), approved under the Mine Management Plan conditions issued by the Minister for State Development and administered by the Department of Energy and Economic Diversification (DEED). The question should therefore be referred to Hon Roger Cook MLA.
