Professional Services Agreement <br /> Risk and Resilience Assessment <br />Page 1 of 12 <br /> <br />Version2.1 02212019 <br /> <br /> <br />THIS AGREEMENT is between CITY OF ARDEN HILLS (hereafter “CLIENT”) and HR GREEN, <br />INC. (hereafter "COMPANY"). <br /> <br />1.0 Project Understanding <br />1.1 General Understanding <br />The America’s Water Infrastructure Act of 2018 (AWIA) requires community water <br />systems serving more than 3,300 people to conduct a Risk and Resilience Assessment <br />(RRA). The communities have to submit a certification to the U.S. Environmental <br />Protection Agency (U.S. EPA) for each RRA. In general, the AWIA considerations for RRA <br />include: <br /> <br />RRA <br />• Risks to the water system from malevolent acts and natural hazards <br />• Resilience of system components <br />• Monitoring practices for such things as operations, water quality, energy, and security <br />• Financial Infrastructure of the Utility <br />• Use, storage, and handling of various chemicals <br />• Operations and maintenance <br /> <br />In response to the requirements of AWIA, CLIENT seeks assistance with conducting an <br />RRA. Based on the population served by the CLIENT, the RRA needs to be completed <br />and certification submitted to U.S. EPA by June 30, 2021. Subsequent to the RRA an <br />Emergency Response Plan (ERP) needs to be completed within 6 months of the RRA, but <br />no later than December 30, 2021. Following completion of the RRA we will work with you <br />create a new agreement to complete that work given that the scope and schedule will be <br />determined by what is learned during the course of completing the RRA. The RRA will be <br />accomplished in a collaborative manner in which COMPANY and appropriate <br />representatives of the CLIENT would participate. The CLIENT has retained COMPANY to <br />complete an RRA for the water facilities listed below: <br /> <br />1. Two (2) Elevated Storage Tanks <br />2. One (1) Booster Pump Station (Located on Same Site as One Elevated Storage Tank) <br /> <br /> <br />1.2 Design Criteria/Assumptions <br />• The project will follow the Risk Assessment Methodology detailed in AWWA J-100- <br />10: Risk and Resilience Management of Water and Wastewater Systems to <br />complete the Risk and Resilience Assessment (RRA). <br />• According to the AWWA J-100 methodology, the steps to be completed are as <br />follows: <br />1. Asset Characterization – identify critical assets <br />2. Threat Characterization – select appropriate threats and hazards <br />3. Consequence Analysis – calculate consequences for each threat-asset pair <br />4. Vulnerability Analysis – estimate effectiveness of existing mitigation measures <br />5. Threat Likelihood Analysis – calculate threat likelihood
