Indian Oil and Gas Surface Lease Environmental Audits

The primary purpose of Indian Oil and Gas Canada (IOGC) Environmental Audit requirements is to ensure that the surface lease meets IOGC’s Environmental Protection Terms Letter (Terms Letter) that was appended to the original surface agreement and other applicable provincial and federal Acts, Regulations, Directives, Guidelines and Information Letters pertaining to upstream oil and gas sites. The audit must be completed and signed by an independent Environmental Professional. The audit must be carried out under snow-free conditions, preferably during the growing season when vegetation has leafed out. For wellsite an independent audit is required the first year and then every five years thereafter and for batteries and compressor station an audit is required every three years.

Envirotech offers a team of highly qualified individuals with IOGC Audit expertise. Please feel free to Contact our Upstream Liability Management Division for more information or a quote.
