Copper concentrate is shipped by truck from the Bisha Mine to the Massawa Port and goods and supplies transported by truck to site; to increase efficiency, trucks carry loads in both directions, as far as practicable. There were 11,723 one way trips in 2015 with no significant environmental incidents associated with this transport.
Transportation impacts include:
- Energy use: included in the overall energy consumption
- GHG emissions: included in the overall emissions
- Noise and emissions: mitigation measures include using new trucks (with lower noise and emissions) and enforcing speed limits.
- Spill control: copper concentrate is shipped in sealed containers to minimize potential impacts such as spillage and dust. In the event of a spill, the contractor cleans up lost material including potentially contaminated soil under the supervision of mine HSE personnel. Recovered material is returned to the process plant.
- Road accidents: represent a risk due to the number of trips. The contracting company (Transhorn Trucking Ltd.) does implement mitigation measures including using new trucks, managing driver fatigue and enforcing speed limits and other traffic safety measures. BMSC undertakes close scrutiny to minimize impacts once these trucks arrive on Bisha property.
