These guidelines are intended to be used in conjunction with the flowchart in Figure 1 which conceptually illustrates procedural steps to be considered by applicants for new substation construction and for existing substation modifications.
Each question is to be answered with: yes, no, not applicable (N/A), or explain accordingly:
Development of new substations
The following sections apply only if the project involves the development of a new substation.
General:
1) Have you described the existing (i.e. pre-construction) environmental and land-use conditions on the substation site and in the local study area?
2) Does your project incorporate the guidelines contained in Alberta Environment and
Parks’ (AEP) Environmental Protection Guidelines for Transmission Lines (R&R/11-03) document, and if not, have you described what aspects of the project do not incorporate the guidelines?
3) Have you described the potential adverse effects of the substation on the environment, including, as applicable, terrain and soils, surface water bodies and hydrology, groundwater, wetlands, vegetation species and communities, wildlife species and habitat, aquatic species and habitat, air quality, environmentally sensitive areas and land use?
4) Have you described the approach to manage stormwater runoff on the substation site to protect on-site and off-site terrain, soils, surface water quality, groundwater, and land use?
5) Have you submitted a project-specific environmental protection plan or otherwise itemized and described the mitigation measures and monitoring activities that you will implement during construction and operation to minimize any adverse effects of the substation on the environment?
6) Have you identified the government agencies or departments that you consulted with as part of your site selection phase, described any prescribed guidelines and stated in the application how the guidelines will be followed?

7) If the substation is being developed on Crown lands, have you consulted with the regional approvals program area of AEP on the project, regarding siting and the potential disturbance by the project of land with protective notations on the land title and any other surface activity dispositions and described any specific mitigation measures that you will incorporate into the project as a result of that consultation?
8) Have you determined if the proposed development is compatible with any area restrictions and ensured the project is not in an area where development of new transmission facilities is prohibited under federal or provincial authority such as the
Wilderness Areas, Ecological Reserves and Natural Areas Act, Provincial Parks Act or
Willmore Wilderness Park Act ?
9) If the substation site occurs on or is bordered by agricultural land, have you developed procedures and consulted with the landowners and appropriate local municipalities with respect to rules and procedures on preventing the spread of weeds and pests 1 on agricultural land?
10) If the substation site is located on land where soils or vegetation have not been previously disturbed, did you obtain Historical Resources Act approval from Alberta Culture and
Tourism for the project?
Wildlife and aquatic species:
11) If the substation is proposed within or adjacent to a wetland or potential fish and wildlife habitat:
(a) Have you described consultation with AEP in regard to any Water Act or Wildlife Act related aspects of the proposed substation, described any AEP prescribed guidelines and stated how the guidelines will be followed?
(b) Have you described the results of a self-assessment under Department of Fisheries and Oceans Canada (DFO) guidelines or, if necessary, have you described the results of a DFO review of the project?
(c) Have you described any outstanding wildlife, vegetation, or aquatic issues identified by AEP or DFO biologists regarding the proposed development, which have not yet been fully addressed?
12) Have you described any mitigation measures you will implement during operation of the substation to minimize the electrocution of birds and animals by substation equipment?
1 Pests are defined in the Alberta Agricultural Pests Act RSA 2000, Chapter A-8.

Substation modifications
Released: October 19, 2015
Page 3 of 6
The following sections apply to the non-emergency salvage, modification or repair of existing substations where soil excavation or disturbance, on or immediately adjacent to a substation site, is proposed.
Basic substation information:
1) Have you provided the substation name with a unique identification number?
2) Have you provided the legal land description, as well as the latitude and longitude or municipal address of the substation?
3) Have you indicated the date the substation commenced operations?
4) Have you described the existing environmental and land-use conditions on the substation site and in the local study area?
5) Have you described the potential adverse effects of the substation modification on the environment, including as applicable, terrain and soils, surface water bodies and hydrology, groundwater, wetlands, vegetation species and communities, wildlife species and habitat, aquatic species and habitat, air quality, environmentally sensitive areas and land use?
6) Have you described how any potential environmental effects of the project will be mitigated?
Operational history to determine the detail and type of information needed:
7) Was any electrical equipment containing insulating oil installed with underlying secondary containment on the existing substation site? If “yes” – ensure you complete line 12 Adequacy Of Secondary Containment.
8) Have you described the duration of any polychlorinated biphenyls (PCB) use on-site and indicated both the maximum and the current PCB content of all fluid-filled electrical equipment that is not hermetically sealed?
9) Was a secondary containment system installed after the substation commenced operations? If “yes” – ensure you complete line 11 Substations Operated for a Time
Without Secondary Containment.

10) For substations currently operating without underlying secondary containment, or in cases where the history of the secondary containment is unknown, have you:
(a)
Completed the steps in Figure 1 Process Flowchart for New Substations and Existing
Substation Modifications
and provided the date that the environmental evaluation was completed?
(b) Described the methodology and summarized the conclusions of the environmental evaluation conducted to assess the likelihood of encountering contamination and any need for further assessment?
(c) Complied with Alberta release reporting requirements (if needed)?
2
(d) Described any additional contaminant assessment or remediation proposed during the proposed work (if needed)?
(e) Described any soil sampling or further environmental evaluation to be undertaken during the proposed work?
(f) Briefly described plans to safely manage, transport and dispose of any used insulating oil during the proposed work?
(g) Briefly described plans to assess and, if needed, transport and dispose of soil affected by releases of regulated fluids?
(h) Described any public health and safety measures to protect the public from environmental hazards during the proposed work?
(i) Described how contaminated or potentially contaminated soil and groundwater is being managed to prevent the migration of contaminants off the substation site?
2 The Environmental Protection and Enhancement Act RSA 2000 Chapter E-12 requires any release of substances that may cause, is causing or has caused an adverse effect to the environment to be reported to
Alberta Environment. An adverse effect is impairment of, or damage to, the environment, human health or safety, or property. The Release Reporting Regulation sets out what must be reported, when, how and to whom reports must be made.
Table 1 of Alberta Tier 1 Soil and Groundwater Remediation Guidelines contains maximum contaminant levels for various compounds. Individual approvals and codes of practice may also have requirements for reporting contraventions of the terms and conditions of the approval or code of practice, monitoring results and sampling programs.
