Boston Logan International Airport Boil Water Order Standard Operating Procedure (SOP)
Brenda L. Enos CHMM, REM Assistant Director Capital Programs &
Environmental Management
April, 2014
Presentation Outline
Discussion Topics:
• Massport’s Past Experience & Future Approach
• Standard Operating Procedure (SOP) Elements
• SOP Development Considerations
Prior Experience: 2010 MWRA Boil Water Order
• Major water pipe break west of the Airport – Boil Water Order Issued from May 1st-4th
• No established Boil Water Order procedures at the time
• Airport Actions – “Tenant Advisories” – Automated notification system -situational
awareness messages (SAMs) – Daily briefing with airlines – Massport Environmental Unit took lead on
water quality issues and testing
Moving Proactively Forward:
• Develop Standard SOP within Massport’s
Environmental Management System (EMS)
4
Regulatory Framework
• Public Uses
– MassDEP/MWRA
• Retail Food Establishments – FDA/MassDEP/DPH
• Watering Points – FDA
• Aircraft Water
– EPA
Boil Water Order Timeline & SOP Key Elements
• Communications Plan
• Response Actions
• Restore/Close Out Procedures
6
Notify Impacted Parties
Manage Contaminated Water & Users
Restore Normal Use
Communications Plan
• Many internal and external stakeholders, including public
• Response Action Plan Flow Chart – Utilizes existing Emergency Response Plan – Ongoing contact with Logan, Local/
Regional Water Supplier, Regulatory Agencies, stakeholders, and public
Communications Plan Continued
• Mass Communication Methods – Tenant advisories – SAMs – Airport Signage – Physical Controls – Intercom announcements
Coordinated Response Actions
• Operate valves/tanks to isolate contamination • Implement equipment controls and signage • Supplement/supply alternate drinking water • Water quality sampling
Physical Controls
• Manage locations where people drink/use water – Post signage
– Bag water fountains/hydrants
– Provide hand sanitizer
Prioritization of Water Use
• Fire suppression systems • Non-potable Uses in
Terminal Areas and Other Public Areas
• Alternate Sources for Drinking Water and Filling Planes
• Potential Reductions or Bans
Drinking Water Distribution
• Boil water orders may last up to 7 days + • Airport has storage for 2 days • Distribution plan to bring water in from external
sources
Water Quality Sampling
• Sampling and analysis plan – Bacteria (total coliform and e.coli.)
– Chlorine
– Standard heterotrophic plate counts
• Field kits – Immediate Results
• Lab testing – 6 hour hold time, rush for 24-hour TAT
Restore Service/Close Out
• Boil water order lift notifications
• Water line flushing
• Water quality sampling
• Physical controls removal
• Localized repair and maintenance
• Specific requirements for food establishments
• Documentation – response summary & lessons learned
SOP Development Considerations
• Communications – Coordinate/integrate with established Emergency Response Plan and existing protocols
• Impacted parties and stakeholders – MANY players
• Infrastructure – water distribution and fire suppression mapping/knowledge is critical for isolation & sampling
SOP Development Considerations Continued
• Water Needs – use, capacity , prioritization & alternate supply
• Sampling – location accessibility & lab TAT
• Physical controls – #, procure, store, deploy & remove
• Responsible parties – who, what & coordinate
