Chapter 4 – Mitigation Monitoring and Reporting Program
4.1 INTRODUCTION
Section 15097 of the California Environmental Quality Act (CEQA) requires all State and local agencies to establish monitoring or reporting programs for projects approved by a public agency whenever approval involves the adoption of either a “mitigated negative declaration” or specified environmental findings related to environmental impact reports.
The following is the Mitigation Monitoring and Reporting Program (MMRP) for The Rockaway Quarry Reclamation Plan Project (proposed project). The intent of the MMRP is to ensure implementation of the mitigation measures identified within the Environmental Impact Report (EIR) for the proposed project. Unless otherwise noted, the cost of implementing the mitigation measures as prescribed by this MMRP shall be funded by the applicant.
4.2 COMPLIANCE CHECKLIST
The MMRP contained herein is intended to satisfy the requirements of CEQA as they relate to the EIR prepared for the proposed project. This MMRP is intended to be used by City of Pacifica staff and mitigation monitoring personnel to ensure compliance with mitigation measures during project implementation. Mitigation measures identified in this MMRP were developed in the EIR.
The EIR presents a detailed set of mitigation measures that will be implemented throughout the lifetime of the project. Mitigation is defined by CEQA Guidelines, Section 15370, as a measure that:
• Avoids the impact altogether by not taking a certain action or parts of an action; • Minimizes impacts by limiting the degree or magnitude of the action and its implementation;
• Rectifies the impact by repairing, rehabilitating, or restoring the impacted environment; • Reduces or eliminates the impact over time by preservation and maintenance operations during the life of the project; or
• Compensates for the impact by replacing or providing substitute resources or environments.
The intent of the MMRP is to ensure the implementation of adopted mitigation measures. The MMRP will provide for monitoring of reclamation activities as necessary and in-the-field identification and resolution of environmental concerns.
Monitoring and documenting the implementation of mitigation measures will be coordinated by the City of Pacifica. The table attached to this report identifies the mitigation measures, the monitoring action for each mitigation measure, the responsible party for the monitoring action, and timing of the monitoring action. The applicant will be responsible for fully understanding and effectively implementing the mitigation measures contained within the MMRP. The City will be responsible for monitoring compliance.
