CALEDON OFFICIAL PLAN, CHAPTER 5, SECTION 11 - MINERAL RESOURCES

The current Caledon Official Plan (OP) outlines the Town's policy on aggregate development in Chapter 5, Section 11: Mineral Resources. Section 11 incorporates an amendment, OPA 161, that took several years to produce and involved many stakeholders. The amendment resulted in the map that became Schedule L CHPMARA Prioritization Plan. (CHPMARA stands for Caledon High Potential Mineral Aggregate Resource Area.) In it available aggregate resources were reduced from what had appeared in maps attached to the earlier Caledon Aggregate Resources Inventory Paper (ARIP). Mapping was fine tuned with the elimination of tertiary sources of aggregate: aggregate found within environmentally sensitive areas, wetlands, and core woodlands, as well as deposits too insignificant to licence. Schedule L prioritized the development of aggregate deposits into two classifications: as resource lands for aggregate extraction in the immediate time frame and as reserve lands that are available for future licensing.
Consultants Hardy Stevenson and Associates (HSAL) were retained by the Town to assist with this work and wrote a succinct account of the achievement in the HSAL Spring 2005 Bulletin.

CTC* SOURCE PROTECTION COMMITTEE UPDATED & AMENDED ASSESSMENT REPORTS APPROVED BY THE PROVINCE 2012 *(Credit Valley, Toronto and Region, Central Lake Ontario)

Ontario's Clean Water Act established Source Protection Regions with Committees that monitor and ensure the quality and quantity of municipal water supplies within the Regions. Credit Valley Conservation is one member of the CTCSPA (CTC Source Protection Area).
The CTC report on Caledon municipal wells has reassessed water in the area of Well#3, a source of drinking water for Caledon Village, Alton, Mono Mills, McLeodville, and Skywood Park, as highly vulnerable because of the removal of the aquifer's protective layer which occurred during the extraction of aggregate. While this does not mean that the water in the well is unsafe, the water supply is compromised. High vulnerability ratings require additional alertness and rigorous application of filtration techniques such as chemical treatment including chlorination and coagulation with alum.
An aquifer that is stripped of its sand and gravel protective jacket can accelerate the movement of contaminated water to the well. 
"Aggregate operations were identified in the WHPAs of Caledon Village Well 3 and in Alton Wells 3 and 4. The aggregate operation in the WHPA of Caledon Village Well3 consists of several pits that extend below water table, covering an area of approximately 20 hectares. Within the footprint of the sand and gravel pits, the entire overburden layer has been removed, resulting in the opening up of the underlying overburden, and the loss of the protective layers overlying the aquifer across the gravel pit. Based on this, the vulnerability rating within the area of the gravel pits was increased from medium to high." Section 4.8.5: Assessing Vulnerability of Drinking Water Sources

ALTON/CALEDON VILLAGE ADDITIONAL WATER SUPPLY ASSESSEMENT

The Alton/Caledon Village, Additional Water Supply, Municipal Class Environmental Assessment, Phase 1 and 2 Report , April 2015 from the Region of Peel documents and updates 20 years of studies in Alton and Caledon Villages on the availability of municipal water supplies. It produces projections of the impact of available municipal wells on future population and development demands to 2031. It includes a review of various unsuccessful searches for more municipal water, the most recent in 2015.

CALEDON VILLAGE NEW WELL CLASS ENVIRONMENTAL ASSESSMENT REPORT 

This report is on a compressive Region of Peel Region Groundwater Investigation Program to locate a site for a new, much needed municipal well for Alton and Caledon Villages. Alton receives some of its water supply jointly from Caledon Village area wells. It's a thorough and detailed account of the process that's conducted during a class environmental assessment. It contains all supporting correspondence and documents relevant to recommendations ultimately made by the consultants.
It concludes: "
Unfortunately, for the reasons summarised in Table X below, none of the sites are viable or further development and the Region was forced to abandon the search for a new production well."

STATE OF THE AGGREGATE RESOURCES IN ONTARIO 2010 STUDY: CONSOLIDATED REPORT (SAROS REPORT)  

This consolidated report was prepared by Ministry of Natural Resources and is a summary of information from a series of six studies. Over a 3 year period these studies had input from many stakeholders including representatives from the aggregate industry and community advocacy groups in order to update Ontario aggregate policy after a period of 20 years of administrative changes.
