Sonic receives permit for demonstration tests of PCB destruction process

VANCOUVER, BC-Sonic Environmental Solutions has received its air emissions permit from the Greater Vancouver Regional District (GVRD) for demonstration testing of the company's PCB destruction process. This completes the regulatory approvals process for the demonstration stage which must be carried out before Sonic can have its proprietary PCB destruction process approved for commercial use in British Columbia. Sonic will commence the demonstration tests as soon as the required bodies involved in the testing are co-ordinated. Three tests will be monitored and results reported to the Ministry of Water, Land and Air Protection (WLAP) as part of a formal request for approval of the process for commercial use. Much of the core process is already at full scale and has been proven in development. Exhaustive emissions and treatment samples will be taken for analysis to replicate the results previously obtained and independently validated. Sonic completed commissioning of Plant One (the demonstration facility) last month, on schedule, and is now able to conduct monitored treatment of PCB contaminated soils as required by the Ministry. "Although it has taken longer to receive the GVRD permit then we expected, we are still on track for commercial operation this year," said Sonic president and CEO Adam Sumel.
