  1. 9/15/16 Prince William Sound Dispersants Monitoring Protocol: Implementation and Enhancement of SMART (Special Monitoring of Applied Response Technologies) DRAFT July 2016 The Need for a PWS Dispersants Use Protocol • PWSRCAC volunteers and staff saw the need for: * additional biological information, especially pre-spill * additional pre and post-spill monitoring * using lessons learned from BP Deepwater Horizon Spill * enhanced decisions to be made: - about starting and/or continuing applications - based on a more complete and accurate understanding of the ~ biological resources and ~ the efficacy of the application 1

  2. 9/15/16 Developing the PWS Dispersants Monitoring Protocol • Initial research and work gathering and reviewing existing protocols * Merv Fingas, Spill Science and SAC Review • Taking Fingas’ technical review document and using it to build on the SMART protocol w/a focus on PWS via: * Project Team and Stakeholders * Nuka Research and Planning * SAC Review What is a Monitoring Protocol? • Specific process used to collect information and make decisions about whether to start or stop applications, and to document effectiveness, fate, and effects. * guidance * surveys * testing * checklists * verification 2

  3. 9/15/16 The Existing Protocol – Special Monitoring of Applied Response Technologies (SMART) • Developed by federal agencies to inform decision-making during dispersant applications •PWSRCAC saw the opportunity and need to include: * additional biological information (esp. pre-spill), * lessons learned from BP Deepwater Horizon Spill - driven by the widespread and sustained use of dispersants during that spill PWS Dispersants Monitoring Protocol • Enhancements: * Adding to pre- & post-application data collection * Emphasizes adding biological monitoring parameters * Identifying thresholds for dispersant efficacy & effects in Alaska * Incorporating long-term monitoring • SAC thinks this is an important advancement for the concept of dispersants monitoring and decision making, both before and after the application process. 3

  4. 9/15/16 Summarizing the monitoring enhancements to SMART MONITORING SMART PROTOCOL PWS ENHANCEMENT Survey and data collection on background Not included Pre-application conditions and ecological sensitivities to surveys inform dispersant use decisions and design of enhanced monitoring process Recommend use of bottle test to improve No method specified Field efficacy accuracy and simplify/expedite process tests Visual assessment of efficacy by trained Establishes thresholds for timing of visual Tier 1 observer based on qualitative evaluation assessment (w/in 30-60 minutes of application) and quantitative threshold for min. effectiveness determination at 50% Real-time instrument monitoring using Use of integrated fluorometer/particle size Tier2 fluorometry, supplemented by sample analyzer to evaluate effectiveness against collection and analysis. No quantitative quantitative thresholds for concentrations thresholds. Recommends additional data collection to Specifies additional monitoring and analytic Tier 3 expand evaluation of dispersant techniques to evaluate hydrocarbons. effectiveness and explore fate and behavior Specifies toxicological assessment of oil. Biological/toxicological monitoring techniques and equipment, and identifies Fitting into the into the response and decision-making framework • Developed for use in PWS, but could be applied in other regions • Accommodated into the broader response and decision-making framework when an oil spill occurs by: * adding additional processes coordinated with SMART organization * nesting within established SMART Tier monitoring procedures * using this document as a companion to the SMART Protocol 4
