The chair of the meeting Garry West said the decision to relocate the 10 megalitre dam to a location further north on the site was passed unanimously by all four members on the panel.

The development application documents outlined CTK Natural Resources proposed to change the location of the water storage dam associated with the Lookout Road quarry within Bago State Forest.

"Significant engineering and ecology issues were apparent with the previous approved dam location on the southern side of Milligans Road," the document stated.

According to the Environmental Impact Study conducted for the relocation, the proposed (modified) location of the dam is "superior to the originally approved location".

"On the grounds of geology, dam safety, increased catchment, reliability, constructability, preservation of hollow bearing trees, reduced noise to residents in the region, reduced visibility to residents in the region, accessibility, and closer proximity to the quarry that it is designed to serve," it states in the conclusion.

According to the ecological assessment conducted by Biodiversity Australia, the new site is situated within an existing forestry plantation which is due to be harvested in the near future.

"The new dam location would have a much lower ecological impact than the previous dam site due to the absence of hollow-bearing trees and poorer quality habitat," the report said.

"No threatened fauna species were recorded on site.

"The vegetation on the site would only provide a very minor foraging resource which occurs extensively in surrounding vegetation.

"The removal of vegetation is not predicted to place any species at risk of further decline."

The development application for the hard rock quarry was initially passed in February 2017, where the meeting of the Northern Joint Regional Planning Panel was hosted at Wauchope's Rotary Youth Centre.

The quarry would extract approximately 200,000 tonnes of material per year for 20 years.

The total land area for the project is 188ha (465 acres). The land area for the quarry and processing plant is approximately 20ha (49 acres).

A number of passionate residents addressed the meeting in 2017 to voice their concerns about the quarry, including Helen McCready.

"I'm also concerned about the construction of a water storage dam and the flow-on affect to Herons Creek," she said in her 2017 address.

"The report says the water in the creek is already downgraded, wouldn't this make it worse?"
