Volume2E – Mines and Quarries thatpropose a management objective of erosion controlover sediment control. The focus of the WamboErosion and Sediment Control Plan is primarilysediment control. The control measures proposed insection 3 of the ESCP lack appropriate detail fordispersive soils/spoils observed at the Wambo site anddesign standards for erosion and sediment controlstructures at Wambo nominated in the ESCP section 4are not consistent with the requirements of Table 6.1 ofSoils & Construction. Volume2E – Mines & Quarries.(b) The Plan identifies activities that could cause erosionand generate sediment and refers to Figure 1B in theMining Operations Plan for the location of erosion andsediment control structure on the site.(c) Section 4 Erosion and sediment control plans Table 4and Figure 2 provide location, function, and capacity oferosion and sediment control structures(d) The Plan describes measures to minimise soil erosionand potential for sediment migration to downstreamwaters in section 3.3. Section 4.5 Mine WaterManagement describes measures to minimise soilerosion but does not address the main mechanism forerosion risk and sediment migration on site which issoil dispersion.4/33 The Surface Water Monitoring Program shall include:(a) detailed baseline data on surface water flows and quality inthe Wollombi Brook, and North Wambo, South Wambo, andStony Creeks;(b) surface water impact assessment criteria;(c) a program to monitor surface water flows and quality in theWollombi Brook; and North Wambo, South Wambo, and StonyCreeks;(d) a program to monitor bank and bed stability in North Wambo,South Wambo, and Stony Creeks;(e) a program to monitor the quantity and quality of the vegetationin the riparian zones adjacent to North Wambo, SouthWambo, and Stony Creeks; and Surface Water MonitoringProgram, Aug 2005 Environmental MonitoringProgram, Mar 2006 Surface Water MonitoringProgram, Nov 2009 Erosion and SedimentControl Plan, Feb 2010(a)Yes(b)Yes(c )YesThe Surface Water Monitoring Program was initially submitted toDoP and approved in 2005. The Site Water Monitoring Programwas revised in November 2009 and the Plan approved by DoP on28 April 2010.(a)(b)(c)Section 4 Baseline Surface Water Data – providesdetailed baseline data on surface water flows andquality in the Wollombi Brook, and North Wambo,South Wambo, and Stony CreeksSection 5 Surface Water Quality Criteria – providesSurface water impact assessment criteriaSection 6 Surface Water Monitoring Program - aprogram to monitor surface water flows and quality intrevor brown & associates 62applied environmental management consultants
