In 1996, Alberta Resource Development (Lands and Forest Services) approved the disposal of drilling fluids on client-controlled access roads and leases. This type of disposal is defined as Disposal On License of Occupation in green areas (DOLOC and MSL).
In 1998, Tansley Associates was the first company to receive approval from the British Columbia Ministry of Water, Land and Air Protection, Agricultural Land Commission and Oil & Gas Commission to land-spray on agricultural lands in British Columbia. Tansley Associates was integral in the development and eventual implementation of guidelines that led to land-spraying on access roads and leases in B.C.
Today, Tansley Associates remains a leader in DOLOC in Alberta and DOALP in B.C. Our team of environmental scientists, planners, biologists, soil scientists and experienced field technicians ensure success for both small and large scale projects.
In conjunction with Wabasca Vacuum Services Ltd, Tansley Associates offers a full range of equipment and services for land-spraying, sump sampling, and environmental project management during winter drilling programs.
