With the proposed Hidden Quarry property zoned Greenlands, why does JDCL still want to destroy this environmentally sensitive land?

JDCL argues that aggregate supply is paramount, that a ‘close to market’ source trumps all concerns, and that they will rehabilitate the site when extraction is complete.  Their rehabilitation plan attempts to show that the effects of mining will not be detrimental to the environment.  The plan provides for some tree planting, but the significant result will be two lakes deep in the bedrock in what is now a valuable water recharge area in the Paris Galt Moraine which produces clear, cold water an increasingly rare commodity in southern Ontario.  The fact that excavation would break into the ground water system means that the new lakes would be ‘surface water’ and that the local ‘groundwater’ system would be permanently subject to surface water pollutants.
