A
summary of the Implementation Schedule of Environmental Mitigation Measures
(EMIS) is presented in Appendix E. All
necessary mitigation measures at this stage of works were implemented properly.

With
implementation of the recommended environmental mitigation measures, the
contract¡¦s environmental impacts were considered environmentally acceptable.
The weekly environmental site inspections ensured that all the environmental
mitigation measures recommended were effectively implemented.
