Coalbed Methane (CBM)
CBM projects will require the dewatering of coal seams to assist with methane production. If the groundwater is saline (> 4,000 ppm total dissolved solids (TDS)), Alberta Environment and Protected Areas (AEPA) authorization is not required.
If the project requires the diversion of non-saline groundwater (< 4,000 ppm TDS) from the coal seam, AENV authorization is required, and the Guidelines for Groundwater Diversion for CBM Development must be followed.
A) Complete a Preliminary Groundwater Assessment Report, including:
- A description of the CBM investigation
- The results of a field-verified water well survey
- A detailed assessment of the geology of the project area
- A description and discussion of the hydrogeologic conditions of the project area
- A conceptual Water Management Plan
- This report must be submitted to and approved by AEPA prior to drilling / re-completion or groundwater diversion.
B) Complete a technical report supporting an Application Under the Water Act, including:
- An overview of the existing hydrogeologic information supported by field-verified water well survey data
- Aquifer testing data
- Groundwater quality data
- An operational Water Management Plan
- A cumulative impact assessment
- Groudwater monitoring data recommendations
HCL has prepared and submitted hundreds of technical reports to AEPA to support groundwater diversions in Alberta.
