It was found that there were recently placed green waste material around the center of site. There was some
leachate/contaminated stormwater runoff observed due to the heavy rainfall at the time of inspection. It was
noted that the discharges were contained in the center of the site, and no discharges were observed off site.
There was some odour noted off site, however it was deemed to be minor at the time of inspection. The
Company was advised that there were no issues …
The site was
found to be generally well maintained and tidy during inspections, and all consent conditions were being
complied with. No objectionable dust or odour effects were observed, bunding was well maintained and site
contouring was adequately directing all quarry runoff to the stormwater settlement ponds. Discharges after
heavy rainfall were clear.
