No.: 7210-003 March 26, 2019 Executive Summary The Glamorgan waste disposal site operates as a waste transfer station under the Ministry of the Environment, Conservation and Park Provisional Certificate of Approval No. A330401, most recently amended April 5, 2011. The Glamorgan landfilling operation was officially closed in July 2002, with final capping of the mound having occurred in 2006, and now operates as a transfer station. The Glamorgan waste disposal site is on Lot 30, Concession V, in the geographic township of Glamorgan, in the Municipality of Highlands East, County of Haliburton, approximately 3.0 km east of the Hamlet of Gooderham, south of Highway 503, at 1070 McColls Road. Groundwater elevations recorded in 2018 indicated that the overburden groundwater flow was to the south-southwest in the shallow overburden layer and to the south in the deep overburden, towards the Irondale River. Based on the water quality results from 2018 there was a dilute leachate plume emanating from the waste mound towards the south. Due to site closure and natural attenuation, the leachate plume was weak and did not extend laterally much beyond the actual waste pile. The 2018 water quality data confirmed that the surface water quality in the Irondale River downstream of the Glamorgan waste disposal site is similar to background surface water conditions and was not adversely impacted from the waste disposal site. The site compliance was determined in 2018 by completing an assessment of the water quality at groundwater monitoring wells OW8, OW8B, OW9, and OW9B using the Provincial Water Quality Objectives and the Ministry of the Environment, Conservation and Park Guideline B-7 Reasonable Use Concept. Based on the assessment completed to date, the Glamorgan waste disposal site was interpreted to be in compliance with both the Reasonable Use Policy and the site-specific Trigger Mechanism. It was estimated by the Municipality of Highlands East that 111.84 tonnes of blue box materials and waste electrical and electronic equipment were diverted from the site. In addition, Cambium Inc.
