Oil & Gas
Oil & gas in Alberta has a special system to speed up clearance of the installation of well sites. Oil & gas companies can use the Public Version of the Significant Historical Sites and Areas Listing to see if the location of the proposed well site has an HRV. If there is no HRV for the proposed area, the project can proceed. If there is an HRV for the proposed area, the company can either try to submit an HRA Clearance themselves or contact an archaeological consultant. The archaeological constulant has a copy of the Restricted Version of the Significant Historical Sites and Areas Listing, which is more complete than the public version. The consultant can determine if there is likely to be an impact on any historical resources. The consultant will complete an HRO and HRA Clearance form if they feel there is no potential for adversely affecting historical resources. If there is a strong possbility that the wellsite will disturb a known historical resource, an HRIA is required before construction of the well site can begin.
The fieldwork for a single to few well pads with short gathering systems can be completed in a day. Large-scale pipelines and oil sands projects may take the bulk of the summer months.
