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
