SEA TEAM 
Overview
• Material availability continues to be impacted by domestic and         
international environmental health and safety (EH&S) regulations, 
industrial pollution prevention goals and related vendor economics
• SEA is an integrated team that works to identify communicate and        ,   
address safety and environmentally driven materials obsolescence 
issues and pollution prevention opportunities
– Proactively identifies potential problems, makes efficient use of resources         
and expertise in mitigation 
– Uses a systems focus on issues driven by current or future EH&S drivers

CHALLENGES TO NASA   
PROGRAM ENVIRONMENTAL ASSURANCE
• Increase in US and State regulations, complex environment
• Increase in EU regulation and potential for impact to vendors
• Direct impact of regulations on vendors and sub-tier suppliers        
• Industry decisions to proactively replace hazardous materials even 
before regulation, sometimes with little or no notice
• Difficult to identify drivers and evaluate risk      
• Change in assumptions and direction due to SSP 2010 retirement
• Supporting Missions: operational vs. development; SOMD vs. 
ESMD lti l j t lif t; mu p e pro ec  e s ages

ENVIRONMENTAL ASSURANCE
IMPLEMENTATION CHALLENGES
• Confusion: environmental tasks, roles and responsibilities
1.  Environmental Assurance vs. Environmental compliance and NEPA
2.  Environmental Assurance Roles (Program/HQ/RRAC/TEERM/Centers)
3.  Materials vs. Environmentally driven materials obsolescence
• Confusion: SEA work/ownership of issues vs. SEA facilitated communication and 
discussion
• Many unique environmental assurance products 
• Some difficulty getting contractors to share data, SSP elements report relevant 
work
• Sometimes team is out of the loop until something becomes an issue
• SSP focus is obsolescence – hard to justify Pollution Prevention work (depends 
on project life cycle)
• Difficulty in identifying if and where an at risk material is used in SSP
• Proactive identification of drivers is difficult (particularly industry drivers)
• Application of risk assessment scorecard and SIRMA process to multiple element          , 
multiple impacts, multiple opinions, long term risk with high uncertainty
• Uncertainty concerning SEA future makes planning difficult 9

SUCCESSES
• SEA Team: available expertise to address materials and environmental issues, 
provide technical feedback to SSP, CxP and HQ
• Face to face meetings: communication, data sharing, interfaces, team building
I t f HQ RRAC TEERM EMO AFSC• n er aces: , , , s, 
• Communication: Notices, products, meetings
• Reporting:  annual report, status report, monthly updates 
• Risk Management approach: standard approach to risk assessment, SIRMA
• Success using technical sub-teams to address specific issues
• Success working with HQ on regulatory input and reviews
• Team is comfortable bringing up any issue; success in communicating to risk 
owners outside of SEA team    
• SEA Issues
-- HFC 141b: reporting and coordination with HQ, RRAC, CxP, Primes
-- Lead free electronics: identified SSP risks, element specific mitigation 
t t is ra eg es
-- PFOA: identified vendor-driven risk, sub-team working with industry to 
evaluate risk

BENEFITS
SEA is reducing risk to the SSP associated with environmentally driven materials 
obsolescence by:
• Identifying regulatory impacts
• Working with regulators to minimize the adverse impact of regulatory restrictions
• Maintaining essential use exemption
• Providing notice and technical support concerning vendor changes and materials 
concerns
• Sharing material replacement data and working mitigation efforts
• Communicating potential issues and risks to management and other technical 
forums
Interfacing with DoD and other agencies to share data/collaborate•         
• Identifying and mitigating environmental and material obsolescence concerns
Constellation, ISS and other Projects have benefited from established SEA activities          
• HCFC 141b process and products greatly supported CxP exemption
• Regulatory matrix and review process in place
• Common issues and risk assessments
• Established team of expert contacts

• Expanding interfaces 
• Major risk assessment process improvements

LESSONS LEARNED
• Effective program environmental assurance requires:
– established requirements and management processes
– management support and adequate resources
– proactive, action orientation
– committed and strong program management environmental   , , , 
material, and regulatory team
– ongoing documentation 
• Effective approach includes:   
– systems focus and dedicated interdisciplinary team
– risk management approach
– proactive regulatory processes
– effective communication and active interfaces
– materials and environmental technical expertise
– integrated technical and project management expertise
13
SPACE SHUTTLE PROGRAM
Shuttle Propulsion Office (MSFC)
NASA Marshall Space Flight Center, Huntsville, Alabama
LESSONS LEARNED
• Multiple programs with interdependent and overlapping issues should 
coordinate to avoid mission impacts and ensure cost-effectiveness
• All stages of a project life cycle should consider environmental 
discipline, including design
• Programs should be encouraged to reduce environmental footprint
• SEA identified materials to avoid or address include:       
-- HCFC 141b Blowing Agent
-- 1,1,1 Trichloroethane
-- Cadmium Replacement in Plating Applications
-- Hexavalent Chromium Replacement in Conversion Coatings and Primers
L d F El t i-- ea - ree ec ron cs
-- Perfluoroalkyl Sulfonates/Perfluorooctanoic acid
-- Brominated Flame Retardants

SEA FUTURE
• SSP and CxP both carry risks related to loss of SEA capability
• Have had discussions with MSFC Engineering, RRAC, TEERM, HQ 
Environmental, CxP, SSP Propulsion Office, PSE&I, SSP Transition Team 
and CxP Transition Manager on need and approach to transition 
• Also considered HQ or SOMD/ESMD-level team
• All agree on need for SEA like team to support CxP 
• Provided PPBE input to CxP and Human Space Flight Capability exercise
• No current CxP or HQ funding support or commitment
