An Ottawa company mining a quarry in Kanata says it will lose millions of dollars in business if a planned business park is built next door.

Taggart and Shenkman Corporation have a plan to develop 75 hectares of land into a business park at Highway 417 and the Huntmar Drive interchange, near the site of the future Tanger Outlets mall.

To do so, they’d be building into a 500-metre, provincially-required buffer zone around the quarry owned by Karson Aggregates because of the blasting that happens there.

That company said the plan is for construction to happen within four metres of their quarry, taking away a chunk of what they could work on.

"We have to mitigate 500 metres into our quarry, we have to start this mitigation process," said Erwin Schultz, vice-president of Karson Aggregates, which he added would cost the company $69 million.

Plan goes to council next month

The developers said there will be at least 75 metres between the business park and the quarry, following other city rules.

"They are not proposing being four metres from the quarry operation," said spokesman Miguel Tremblay.

"I don't want the committee to leave here thinking we're actually proposing buildings within four metres of the quarry blasting."

Members of Ottawa’s planning committee recommended city council approve the business park plan, which would mean changing its zoning bylaws and official plan.

Barrhaven Councillor Jan Harder said she’s concerned noise and floor vibration from the quarry will affect businesses in the new park.

"There will be noise, will the ground shake? Yes," said Danny da Silva, a consultant hired by the developers. "But these are not levels we should fear in terms of damage."

Ottawa city council will vote on the plan Sept. 10.
