Irving Oil’s refinery in the Canadian province of New Brunswick spewed an excessive amount of ash-like catalyst into the surrounding city of Saint John at least a dozen times since 2010 as regulators launched and later abandoned a study of its health impacts, according to filings reviewed by Reuters. The previously unreported documents from Irving and provincial regulators, obtained by Reuters under the province’s Right to Information Act, raise fresh questions over the company's environmental record and the province’s capacity to regulate industry. Such concerns have come into sharper relief since the company agreed in 2013 to become a partner in TransCanada’s proposed Energy East oil pipeline project, which would bring more than 1 million barrels of oil daily from Alberta to the Saint John shoreline in eastern Canada.
