3 1. INTENT Provide monthly updates of environmental performance and assess compliance against specific consent conditions. To keep the company and stakeholders informed of the mine s environmental performance and maintain a transparent and accountable reporting system to inform all relevant stakeholders. 2. SCOPE This report covers various environmental conditions that are monitored at Integra Underground. These conditions, where applicable, are measured against consent criteria to determine compliance. Including; Water monitoring; Noise monitoring (quarterly); Air quality monitoring; and Environmental conditions over the month. 3. DEFINITIONS TSP Total Suspended Particles PM 10 Particulate Matter less than 10 microns in diameter HVAS High Volume Air Sampler SWL Standing Water Level, the groundwater level measured from the top of the piezometer casing. 4.
