Decontamination Preparedness and Assessment Strategy Water Security Division ASDWA Webinar Series for the State Security Coordinators August 23, 2017
Outline Explain the purpose and benefits of the Decontamination Preparedness and Assessment Strategy Provide Tool Overview State- EPA Partnerships 2
Think About this…. Do utilities in your state incorporate the remediation process in their Emergency Response Plan (ERP)? 3
Decontamination Preparedness and Assessment Strategy (DPAS) • Designed as a interactive preparedness tool • Provides information on the remediation process of a contamination event at a water utility • Provides an efficient process for utilities to address the complexities of remediation 4
DPAS Includes: • Information on water and wastewater treatment and infrastructure decontamination • Worksheets, checklists and other resources to aid the remediation process • Information on key statutes and regulations relevant to remediation. • The principal roles and responsibilities to increase understanding of the Incident Command System (ICS) 5
DPAS - Benefits for States and Utilities v Explains the steps involved in the remediation process v Provides utilities with a printable strategy, including actions that can be taken prior to an event to increase preparedness v Provides a list of resources and other tools available to help prepare for an event v Provides an overview of statutes and regulations applicable to contamination incidents v Provides an overview of important public health and environmental safety considerations during an remediation event. 6

Characterization Phase Key Decisions q What is the extent of the contamination? q Is treatment needed? 9
Characterization Phase 1. Characterize the Impact of the Contamination 2. Determine Clearance Goals 3. Develop Characterization Strategy 4. Implement Characterization Strategy 10
Characterization Phase Decision Framework Proceed to Clearance Proceed Phase to Decontamination Phase 4. Is natural attenuation adequate to eliminate the public health impacts based on exposure assessment, water and infrastructure impacted, contaminant information, and effectiveness of public notification? NO YES 11

Clearance Phase Key Decisions q Have the clearance goals been met? q What incident reports need to be completed and records retained? 17
1. Develop and Implement the Clearance Strategy Clearance Phase 2. Evaluate Results and Decide if the System Has Been Cleared 3. Develop and Implement Final Remediation Activities 4. Complete Incident Report and Perform After-Action Review 18
Clearance Phase Decision Framework Have the clearance goals been met? YES Are there other concerns, such as aesthetic issues or public perception? NO Decision “not cleared” Could the Clearance Goals be too strict? Decision “cleared” 19

22 Preparedness Checklist
23 Decision-Making Framework Checklist
Case Studies Objective is to highlight challenges and the approaches utilities take during the remediation process. Ø Case Study 1 − Drinking water plant affected − Highlight the complexity of the determination of clearance goals and agency (e. g. , CDC and the Public Health Department) roles Ø Case Study 2 − Wastewater treatment plant affected − Highlight the benefits of developing an SAP 24
SCENARIO DEMO
Scenario ØA utility confirmed gasoline contamination within the finished water storage tank located within the distribution system. ØOdor in water and consumer complaints led to identification of gasoline contamination at the 200, 000 gallon ground level finished water storage tank. ØConfirmed high concentration in storage tank and lower concentration in distribution system 26

STATE- EPA PARTNERSHIP 30
States- What Can you Do? q Promote the strategy to utilities/partners q Provide support to utilities as they develop plans § e. g. , Standard Operating Procedures, Waste Management Plan, Sampling Analysis Plan, Remediation Action Plan, etc. q Identify additional resources that can aid utilities during the remediation process q Identify trainings & opportunities for utilities § Encourage and participate in emergency preparedness training and exercises § Provide continuing education credits (CEUs) 31
EPA’s Next Steps • Finalize Strategy – Tentative Fall Publication • Partner with states and EPA regions to promote the strategy • Partner with states and other stakeholders (NRWA, RCAP, AWWA Sections, etc. ) to assist small/ medium size utilities • Conduct DPAS training 32
