Chapter 8: Local Road Environmental Safeguards: 240 and enforcement of recommended mitigation measures, (3) implement the EMP, (4) monitor and evaluate EMP implementation, and review EMP implementation; c. Implementation. The EMS measures designed to control and manage the environmental impact of road projects are implemented in conjunction with the EMP developed for a particular project; d. Environmental Compliance Monitoring (ECM) and evaluation. The monitoring and evaluation of EMS and EMP implementation should be built into the EMPs. This process requires performance indicators for assessing environmental performance. Ideally, such monitoring and evaluation should be carried out by the managing contractor throughout project implementation; The general provisions of DAO 03-30 and its revised manual of procedures, which spell out the monitoring requirements and the format of reports, guide the monitoring of the EMS and its implementation in roadworks. Besides the conditions stated in the ECC issued for the project, further details can be found in the multi stakeholder participation handbook developed under the World Bank–funded Strengthening the Environmental Performance Monitoring and Evaluation System of the Philippine Environmental Impact Statement System project; and e. Review. Management measures contained in the EMS must be periodically reviewed for suitability, adequacy, and effectiveness in managing any issues and impact identiifed. The review is generally informed by the ifndings of environmental performance assessments, reviews, and audits; changes in legislation or policy and strategic priorities; and the need for continuous improvement.
