Exhibit A RARC/aDIS flooding, and potential malevolent acts. The Arcadis Team would also include customized Exercise Evaluation Guides (EEGs), one set per scenario, which reflect the T&EP priorities and capabilities chosen at the T&EW. Also included in the T&EP would be after -action and improvement plan (AAR/IP) guidance and templates and a T&E Record for tracking and documented completed trainings and exercises. Optional Task 2 - Wastewater System RRA Arcadis would complete a wastewater system RRA following the AWWA J100 seven step standard methodology. Existing system knowledge would be leveraged, and an initial needs list provided to the Department prior to a brief Kickoff Meeting. Development of the RRA would include an Asset and Threat Workshop to identify mission - critical assets and relevant associated threats (malevolent, accidental, natural, dependency, and proximity). Following the workshop, a 5 -day consecutive onsite visit of select critical and representative assets would be completed by three Arcadis staff. During the site visit, interviews would also be conducted with key staff. A Consequence and Vulnerability Workshop would then be facilitated to identify and quantify potential impacts based on threat -asset scenarios (for up to 150 threat -asset pairs). Associated vulnerabilities to potential impacts would be discussed with input solicited by the Department. Arcadis would complete the Risk and Resilience Analysis using a Risk Model/Power BI Tool. Risks and threats would be prioritized for potential mitigation. Arcadis would then facilitate a RRA Results and Mitigation Workshop to review and adjust results as needed; identify current, ongoing, and planned mitigation projects and initiatives; and select additional recommended mitigation measures designed to reduce system risks and increase resilience. A high-level cost benefit evaluation of mitigation measures would be completed for recommended timeline and potential funding mechanisms for strategic implementation. Arcadis would submit a Draft Wastewater System RRA for review by the Department, address comments, obtain approval for the final report, and submit the Final RRA to the Department. Optional Task 3 — Incorporation of Wastewater System in the ERP Arcadis would provide wastewater response considerations that include a revision of the Water ERP to incorporate the following: • Update the contact list with wastewater personnel information. • Update the Incident Management Team (IMT) organization chart to include wastewater response personnel. • Develop up to five ISRPs for the following, as example: major line break, power loss, loss of SCADA, pandemic response, and malevolent acts. Conduct interviews to obtain information. • Review threats to the wastewater collection and treatment system and identify mitigation actions and response actions. • Incorporate existing sewer system overflow response plans, as determined. • Update of appendices, including contact lists, forms, policies, equipment, and resources (including generator list and evaluation of power provisions). • Develop a wastewater system overview. • Concept of Operations: Review and describe wastewater response related operations. Include procedures in an appendix. • Review and revise Emergency Action Levels and Initial Response Operations. • Spare Parts and Equipment: Update to include Wastewater and Sanitation spare parts and equipment information. • Recovery: Update to include recovery actions for wastewater. • Detection Strategies: Address Detection Strategies specifically for wastewater. 14
