Concerns were also raised that the green light would allow other companies to explore quarrying other areas near Templeton.
Fulton Hogan's South Island Manager, Craig Stewart, said the company "took on board" what the community and experts said during the consenting process, and the new conditions reflect a "comprehensive assessment" by ECan staff.
“We believe this is the best place for a quarry and we plan to earn the trust of the community by putting our plans into operation and delivering on the consent conditions," Stewart went on to say.
Selwyn MP Amy Adams was "hugely disappointed" by today's decision.
"While the Commissioners have imposed some conditions around the consents, I know this will be cold comfort to the local community, which has worked so hard."
There are 15 days for residents to appeal the decision, however the time and effort required might be too much for the community.
"They have said we can appeal the decision but we're fighting a bloody huge conglomerate with so much money they will keep tipping the money in, there is no way we will beat them."
