The first European settlers, Scottish and Irish soldiers, and early farmers were met with the harsh terrain of the Canadian Shield. It is this rocky shoreline that makes Tay Valley such a spectacular destination for lakeside living. Pristine swimming, mature forests and steep rock faces create the feeling of true Canadiana. To recognize these assets, heritage plaques now mark significant trees, legacy cottages and historic farm properties that have remained in the same families for generations.
As an employer, OMYA has a credible track record. It acquired the former Steep Rock Resources properties in 1988, and made a long-term capital commitment to upgrade and expand the facilities. It earned both its ISO 9001:2000 and ISO 14000:1996 certificates. The plant meets environmental regulations for noise, air and effluent.
The company operates an open pit mine at Tatlock and a mill in Perth. The calcium carbonate it produces is slurried and either railed or trucked to customers. It is used in the manufacture of paper, paints, plastic, food and pharmaceuticals and a variety of other industries. OMYA has about 100 employees of its own and provides another 150 jobs for local trucking and mining contractors. It is providing a reliable source of income for them and pumping about $20 million annually into the local economy.
Little has been said about the fact that water for the plant now comes from seven deep wells. They tap into the groundwater and are licensed to pump up to 800 L/min. The wells will be reduced to standby status. The net effect on the river, given that the underground aquifer is not being depleted, may be close to zero. Time will tell. Read more here.. click

Exploration and Mining History
Originally opened by Angelstone Ltd (1962/3-1971/2), producing ‘ Temple White ‘ dimension stone from 2 quarries on lots 4 and 5. W. R. Barnes reopened the quarry on lot 4 in 1977 and produced decorative stone chips and calcium carbonate filler. They also built a processing plant in Perth. In 1981 the plant and quarry were purchased by Steep Rock Resources Inc. (a subsidiary of Pluess-Staufer A.G.) The quarry has been operated on a seasonal basis , producing 250,000 tonnes per year for year round operations of the mill (1992). Increased levels of production were expected in 1993 as stripping to the N and S of the present quarry was carrried out at that time. Plant capacity was increased above its previous 250, 000 tonnes limit. The Perth mill produced (1992) : high-grade calcium carbonate filler for the paper industry, decorative aggregate, terrazo chips, poultry grit, agricultural limestone, stucco mix and fine-grained filler for floor tile, wall joint compounds, paints and plastics. Diamond drilling was done by Steep Rock Resources Inc. at Lot 5, Con. 4, see assessment file #19, Darling Twp.
08/14/2000 (C Papertzian) – The quarry lies in the W part of a 17.7 km wide marble belt with minor paragneiss and metavolcanics. The quarried rock is white, coarse-grained (2.8 mm) calcitic marble; one of the purest and brightest (>95 %) of its kind. The units being quarried occur in an 85 m wide zone which contains reserves for over 50 years (1992).
Lanark Residents, Cottagers Battle
Giant Swiss Mining Corporation
By Michael Cassidy,
Tatlock and Ottawa
My wife Maureen and I bought a small cabin at Tatlock three years ago with plans to build an addition, keep things simple, and enjoy Lanark’s rural peace and the clean waters of Rob’s Lake. Little did we know what was brewing just down the road, where a giant Swiss corporation was preparing a huge expansion of a quarry to feed a world-scale processing plant for calcium carbonate products located near Perth.
Three years later we are one of eight individuals or groups who have passed a major procedural hurdle and are appealing the expansion plans of OMYA (Canada) Ltd., which is probably the largest single producer of calcium carbonate products in the world. OMYA’s expansion could have serious adverse impacts on the Tay River near Perth; in the vicinity of the OMYA quarry at Tatlock; and for Lanark residents along the Highway 511 corridor and in Lanark village, because of a projected flow of 40 ton trucks from the quarry travelling the corridor every two or three minutes, 24 hours a day and seven days a week.
Besides ourselves the appellants include Lanark residents from Glen Tay, Perth and McDonald’s Corners; cottagers from Bob’s Lake; an environmentalist from Stittsville; and the Council of Canadians, whose particular concern is OMYA’s plan to ship water out of the Great Lakes watershed despite stated Ontario government policy to the contrary.
The issue we are appealing is a permit issued by the Ontario Ministry of the Environment to allow OMYA to take up to 4.5 million litres of water per day out of the Tay River at Glen Tay, 7 km. west of Perth, to be mixed with calcium carbonate to form a slurry that paper companies and other industries are eager to buy at prices of $150 and up per ton.
Calcium carbonate, better known as limestone or marble, is a major product in industry used in everything from paper and plastics to toothpaste and diet supplements. The former Steep Rock quarry at Tatlock that OMYA acquired in the 1990s has an exceptionally large and pure deposit of this mineral.
Ontario has given OMYA a permit to mine up to 4 million tons a year of calcium carbonate, or calcite and another permit to pump up to 3.6 million litres of water per day out of the quarry for dewatering as its operations move below the level of surrounding lakes. The company has invested hundreds of millions to transform its processing plant at Glen Tay, just off Highway 7, into a state of the art facility.
Apart from one Ontario Municipal Board appeal relating to the Glen Tay plant, OMYA’s preparations for expansion have attracted little notice. While permit applications relating to the quarry were posted on Ontario’s electronic Environmental Registry, few of us have time to be so vigilant as to have seen the posting and responded within 30 days. The permits passed through almost unopposed.
That situation changed when OMYA set out to put the final piece in place for its expansion plan – taking water from the Tay because it had outrun the capacity of local groundwater sources to meet its needs for water. When the permit application was posted to the Environmental Registry, an astonishing 283 letters of concern were sent to the Ontario Ministry of the Environment. Ninety per cent of these letters called for some kind of environmental assessment.
There was universal concern that OMYA wanted water from the Tay before adequate information had been collected about its ability to meet OMYA’s needs. The Tay watershed is already stressed because it serves as a reservoir of water to help maintain the Rideau Canal at navigation levels during the summer months. Water levels in Bob’s Lake, the chief reservoir lake, drop by four or five feet every summer as water is drawn for the Rideau system.
This concern was compounded by the lack of current data. The last consistent measurement of water flows along the Tay was made over a dozen years ending in 1927. At some times in the year, the Tay is a river of rocks with a flow so low that almost no water gets through to Perth– read the rest here click
