Utilizing Geoscience Principles: Application of a Web‐Based Mapping Tool to Optimize Environmental
Protection and Regulatory Compliance on a Mega‐Project
Submitted by: Nalcor Energy‐Lower Churchill Project
Project Description
The Lower Churchill Project (LCP) began construction in 2012 and comprises approximately 1600 km of
transmission line and 1500 km of access roads to numerous work fronts. LCP includes two major
projects with the Labrador Transmission Line and Labrador‐Island Link as well as the Muskrat Falls
hydroelectric generation project that span the province from Churchill Falls in western Labrador to
Soldiers Pond on the Avalon Peninsula in eastern Newfoundland.
LCP utilizes intensive front‐end planning with a comprehensive Environmental Management System
(EMS), a collaborative regulatory framework and project environmental awareness to ensure optimal
environmental protection, as well as, maintain compliance with environmental assessment
requirements and commitments, existing legislation and Nalcor Energy’s Environmental Policy.
The use of geoscience technology has proven to be the integral tool allowing LCP to achieve
requirements of the EMS, maintain compliance and fulfill goals of environmental protection. A
comprehensive web‐based, geospatial tool was developed identifying all environmental restraints and
potential land‐use conflicts. This has been augmented with near real‐time updates via reports from a
hand‐held device in the field.
LCP Powerline Project
LCP Powerline is a web‐based mapping application that provides online maps, geographically referenced
data and hyperlinked documents to project staff, contractors, regulators and stakeholders of LCP. The
primary objective of the application is to support environmental monitoring of construction and clearing
activities associated with LCP and provide a tool for regulatory and other stakeholders to obtain
information with respect to all aspects of the project. It is the concept of allowing invested and
interested stakeholders to access the tool and therefore near real‐time data that is particularly
innovative. This has garnered significant attention when presented at conferences, workshops and
presentations. An additional benefit of the Powerline project is the ability to minimize project
interactions with sensitive habitat to ensure optimal protection of the environment throughout
construction. Finally, this tool allows LCP to demonstrate the application of regulatory best‐practices
and compliance with permit conditions so regulatory stakeholders can monitor project activities from
their desktop.
As with any large‐scale construction project, management of data and in this context, spatial data, is
critical. The following key principles were applicable to the application and the process by which it was
developed:
i. Internet‐based solution ‐ due to the large spatial extent of LCP and the fact that project
stakeholders and participants are located in a variety of geographic locations and work in a
variety of computer networks, an internet‐based web application was considered the best
solution to meet the various needs of the users.
ii. Phased approach ‐ a phased approach was utilized to develop the tool. Successful
completion of each phase provided the opportunity to incrementally assess the technical
feasibility and utility of the technology. It also allowed users to become familiar with its
potential and to provide further input into upcoming phases and future development.
iii. Consultation – consultation with a range of users was carried out at various development
stages to ensure the application met as many of the needs of the various users as possible.
iv. Automation – wherever possible reporting and data population processes have been
automated. With the large volumes of data and strict timelines associated with LCP,
automated processes would minimize data errors and improve efficiencies.
The layers available to be added to Powerline include:
Up‐to‐date construction activities
By developing a direct link from the main transmission contractor internal “plan‐of‐the‐day”
data layers to Powerline, the time, effort and potential for error that would have been involved
in acquisition, processing and upload of this data to LCP Powerline was eliminated.
Examples of construction‐related layers are transmission infrastructure, work camps, quarries,
access roads and trails, and clearing progress.
Environmental constraints
Layer obtained from baseline data acquisition and construction monitoring activities include
constraints related to water bodies, historic resources, avifauna, vegetation, protected wildlife,
socioeconomic considerations.
Regulatory constraints
Powerline has a direct link to mapping layers on the Government of NL websites.
Examples of regulatory layers are protected public water supplies, land grants, roads, planning
boundaries, quarry permits, and municipal boundaries.
Users are able to move around the map, click on map features (e.g., transmission towers, stream
crossings) to view details and documents associated with each, and measure distances on the map.
In addition, it is possible to link to related documents in other project cloud‐based services (e.g., stream
crossing reports and photographs). Data updates occur in near real‐time as the on‐site environmental
monitor inputs data via the standardized forms, plots a location or uploads a photograph. For example,
efforts are currently underway to remove much of the manual effort and paper involved with inspection
of stream crossings. Using iPad field data collection software, linked directly to an intermediate web‐
mapping system and from there, directly to Powerline, it is expected that the lag time between field
inspection and stakeholder access to maps, data and document control management system will be
reduced from months to days. These tools improve data quality and availability for all users, as well as
the effectiveness of environmental monitoring. This benefit results in wider coverage and therefore,
better environmental protection.
LCP personnel provide periodic updates to all users and stakeholders to keep them up‐to‐date on
additions and improvements to the system.
This powerful tool provides a number of benefits in facilitating LCP environmental management and
compliance. Powerline allows for regulatory agencies to monitor progress and construction activities
from their computer and assists personnel in completing reports and processing approvals. Powerline
also provides up‐to‐date and continual access to information for construction personnel regarding
environmental constraints. An overview screen shot of the LCP Powerline tool is below, followed by
more specific screen shots of specific layers.

Electronic Reporting
LCP’s on‐site environmental monitors utilize a standard electronic form that allows users to collect data in the field and submit customized forms complete with text, mapping and photos in real‐time. Once submitted these forms can be distributed to a pre‐set distribution list.
The form utilized for LCP has the following features:
• Pre‐set template
– text boxes and drop down menus for contracts, permit conditions, environmental protection procedures, etc.
• Mapping function
– reporter drops pin(s), then reader can click link and be directed to pinned location through Google Maps
• Photo section
– includes automatic date, time, and GPS stamp
• Immediate distribution
– When “send” button is hit – the daily report is automatically sent to all relevant project personnel

A summary of the benefits of using this system includes the following:
• Streamlining and adding flexibility to environmental communications
• Significant time savings due to information availability and automated processes
• Less equipment requirements with improved construction approaches, streamlined reporting and desk‐top monitoring
• Simplifying and standardizing the collection of field data
• Improving the quality of field data
• Immediate distribution among colleagues and stakeholders (opportunity for real‐time data)
• Identification of unique constraints for a location (e.g., permit condition, sensitive environmental area)
• Improved availability to interested parties seeking information
Increased efficiency with on‐site reporting allows for improved resource allocation. This coupled with improved quality of reports results in a highly effective monitoring protocol.
The use of Powerline has resulted in improvements in safety and quality, and a reduction in paper waste and energy use. Powerline provides a real time electronic connection between the project office and the field inspectors. This provides a paperless connection whereby a complete library of information is immediately accessible to field staff anywhere with internet connectivity. Powerline has also been made available to the many project stakeholders and regulators. This has significantly reduced the number of hard copy reports as the report information is available in near real time through the
internet. Online mapping allows inspectors to use GPS coordinates to locate sensitive environmental resources. Travel times and gasoline consumption have been reduced, as well as a reduction in paper copies of field data.
Significant productivity improvements have been realized by the online reporting and information transfer components of Powerline. Daily inspection reports are uploaded to the Powerline GIS and are available immediately for regulatory and stakeholder review. Historically, project reporting was only submitted monthly and quarterly, and required a significant amount of staff time to compile the hardcopy reports and summarize the results. The detailed mapping database available through Powerline allows field staff to know the exact locations of the work front, ensuring a safe travel plan is prepared beforehand. Improvements with quality have also occurred as Powerline allows inspectors to locate, and record GPS coordinates of sensitive environmental features; including rare and endangered species, and historic resources. The mapping is provided directly to the construction contractors who then upload the mapping into the equipment GPS systems. This has proven very successful as the operators in remote areas know exactly where these sensitive features are, relative to their positions. This significantly reduces the risk of encroachment in these areas. Improvements in awareness from regulators and other stakeholders have also been achieved. Powerline is shared with many project stakeholders and aboriginal groups. The information available on‐line through Powerline provides groups and organizations information on project activities as well as progress, including detailed mapping of environmental features and constraints. On‐line access to Powerline provides for the transparent sharing of project information with government and stakeholders. Perhaps the most significant attribute of Powerline is its online availability to project regulators and stakeholders. A unique and robust GIS platform was proactively driven to effectively manage the large volume of spatial data required to implement the Muskrat Falls Project Environmental Management System (EMS). For example, the number of bridges and culverts on the transmission line exceeds 2000, normally each bridge and culvert requires its own permit under the provincial Water Resources Act. The Province does not have the capacity to process this volume of work so Powerline was developed to provide the regulators direct access to data on each watercourse, as a result a single authorization was granted for all watercourses. The tools also provided contractors direct access to detailed environmental mapping, allowing early, proactive, planning of work fronts. To our knowledge, LCP Powerline is the first project designed GIS application used specifically to report
directly to Provincial and Federal Regulators in real‐time and therefore exceeds the standards of
industry peers.
