A schedule, if required for theimplementation of the contingency planning forthe replacement capacity in the event the longterm waste disposal site is not operational, whenthe site has reached the final contours asindicated in condition 3.11.2.9 A summary of the occurrences or incidentswhere this Certificate was not complied with, thereason for non-compliance and the measures tobe implemented to ensure that future noncompliancedoes not occur.Report Reference and Summary• The City is undertaking post closure of the site.• In early 2008, a blockage in the pipe that connects the old mainstation to the main pump station was removed and the pipe wasflushed and video inspected. The old main pump station wasalso cleaned and a high level alarm was installed. No complaintswere received (Section 2.6 and 2.7).• There are no proposed changes in the operation of the site.(Section 2.8).• The waste transfer station was completed in mid 2003 andcommissioned in November 2003. The City now hauls nonrecyclable waste to the Green Lane Landfill in St. Thomas,Ontario. (Section 1.5)• The Conditions of the Certificate were reviewed by City staff andreported to AECOM (formerly Gartner Lee Limited). Theoperation of the site is consistent with the C of A in 2008(Section 9.0).Ambient Air MonitoringC of A Reporting Requirement14.2.1 The results of the monitoring program, includingany off-site exceedances.14.2.2 Any predicted off-site exceedances, based uponthe monitoring results and upon the anticipatedwaste to be landfilled in the next year.Report Reference and Summary• The highest measured ½-hour vinyl chloride concentration was0.29 µg/m 3 , measured on December 27, 2008 in the residentialarea adjacent to the landfill. Measured concentrations weremuch less than the MOE’s ½-hour POI standard (1µg/m 3 ). The½-hour limit can be found in Schedule 1 of O. Reg. 419/05. Atotal of eight samples were collected in 2008.• The 2008 survey included measured concentrations ofpolychlorinated dibenzodioxins (PCDDs) and polychlorinateddibenzofurans (PCDFs) from which the total toxicity equivalent(TEQ) concentrations were determined. The highest measured24-hour TEQ concentration was 0.0434 picograms toxicequivalent per cubic metre (pg TEQ/m 3 ) measured on December11, 2008. Measured concentrations were much less than theMOE’s 24-hour air quality standard (5.0 pg TEQ/m 3 ). Thissurvey was included to measure the downwind impact from thelandfill gas powered generators (Section 7.1.2).• It is recommended that same sampling program be continued in2009. Eight ½-hour samples should be collected to allow fordirect comparison with applicable MOE guideline limits for vinylchloride. The MOE’s final guideline document “Operating Manualfor Point Source Air Quality Monitoring” should again be(111414_2ra_apr29-09_city_of_guelph.doc) - iii -
