Environmental Management System Integration of EMS into Project Execution – All Components • Design Requirements • Technical Specifications • Procurement Packages • Bidder Evaluation • Kick-Off Meeting Support • Weekly Reports to Stakeholders • On-Going Field Monitoring • Use of Powerline by all stakeholders 16
Collaborative Regulatory Framework Blanket Permits • – Water crossings (>1900) – Quarries (>500) – Historic resources – Vegetation clearing Proactive Reporting • – Online reporting – Powerline updated constantly – Weekly report to all regulators Monitoring Tools • – Electronic forms (iPad) – Real-time field reports and constraint monitoring 17
HVac/HVdc Construction Monitoring • Dedicated on-site environmental monitors at each work front • Real-time access to all EMS components via satellite and internet connections • All monitors use an interactive prontoform database and iPad that provide inspection forms and direct connection to Powerline and the project office • Dedicated environmental permit coordinators, engineers and planners 18
Real-Time Internet Reporting • Pre-set Prontoform templates • GIS / GPS Mapping functions • Real-time photograph transfers • Immediate distribution to project office coordinators and engineers • Field (Camp) access to Powerline database and constraint mapping 19
Environmental Effects Monitoring Program Purpose is to monitor the overall project • effects and to confirm the predictions of EA and fulfill EA commitments LCP has implemented more than 15 • comprehensive environmental effects monitoring programs Key programs include: • RWM caribou – MM caribou – Newfoundland marten – Newfoundland caribou – Avifauna – HHRA – 20
