CRRT OIL SPILL RESPONSE SUMMARY MAP
Dispersant Mission Planner (DMP2) • The new Dispersant Mission Planner 2 (DMP2) is a tool that spill responders and planners can use to assess dispersant application system performance. • DMP2 is an update to the Dispersant Mission Planner that was originally part of the Spill Tools software collection.
DMP2 new features: • DMP2 enables Oil Spill Removal Organizations (OSROs) to evaluate Effective Daily Application Capacities (EDAC) for different dispersant application systems, using DMP2's EDAC Mode. This allows OSROs to evaluate compliance with the dispersant application requirements in new Coast Guard rules.*
DMP2 new features: (cont) • In Operational Mode, DMP2 provides general performance estimates for the application of dispersants involving a specified oil spill concentration, application platform, and scenario. It can be used to refine and optimize system configurations and to examine staging and logistical support.
NOAA Dispersant Mission Planner 2 (DMP2) • EDAC Mode – Cited in recent USCG final rule – Enables vessel and facility response plan holders to evaluate Effective Daily Application Capacity for aircraft platforms (no vessel EDAC data in DMP2) • Operational Mode – Provides general performance estimates for the application of dispersants involving a specified oil spill concentration, application platform, and scenario
From Final Rule, page 45010 for facilities • "The applicability requirements for facility response plans are found at 33 CFR 154.1015. These applicability requirements specify that a facility response plan is required to be submitted for approval if a facility is capable of transferring oil or hazardous materials to a vessel that has a total capacity of 250 bbls or more."
8.1.1 • A facility owner or operator must plan either for a dispersant capacity to respond to a facility’s worst case discharge (WCD) of oil, or for the amount of the dispersant resource cap as required by § 154.1045(i)(3) of this chapter, whichever is the lesser amount.
Vessels • For vessels see page 45027 § 155.1035 Response plan requirements for manned vessels carrying oil as a primary cargo...and • § 155.1040 Response plan requirements for unmanned tank barges carrying oil as a primary cargo. • See also page 45028 § 155.1050 Response plan development and evaluation criteria for vessels carrying groups I through IV petroleum oil as a primary cargo. • for Worst Case Discharge see page 45029 • APPENDIX B TO PART 155 — DETERMINING AND EVALUATING REQUIRED RESPONSE RESOURCES FOR VESSEL RESPONSE PLANS

DMP2 and the new CAPS Final Rule • 33CFR Parts 154 and 155 Vessel and Facility Response Plans for Oil: Removal Equipment Requirements and Alternative Technology Revisions, Final Rule (effective date September 30, 2009). • Vessel Response Plan compliance with CAPS must be on or before February 22, 2011. • Plan holders can download the DMP2 and other spill tools from the Internet at the following URL: http://response.restoration.noaa.gov/spilltools. • While the Coast Guard will use this calculator to assess plan holder dispersant plans, plan holders are not obligated to use it as a planning tool.
Highlights of new final rule… • Plan holders operating in areas that are pre-authorized for dispersant use are required to have dispersant resources available. • At least 50% of dispersant capability for each tier is required to be by fixed- wing aircraft. • Dispersant application must begin within 7 hours of Federal On Scene Coordinator’s approval of dispersant use. • Aerial tracking capability must arrive on-scene prior to the arrival of Tier 1, Tier 2, and Tier 3 response resources and will: – Provide info on spill location, size, and trajectory – Provide guidance to response assets, including recommendations for response tactics – Evaluate effectiveness of dispersant application – continuous aerial tracking is appropriate to track dispersant operations (see Dispersant Application Observer Job Aid from NOAA and USCG web sites)
Final Rule-monitoring • Another commenter recommended that plan holders be required to have the equipment and capability necessary to implement the special monitoring of applied response technologies protocols for dispersant monitoring.
Con’t • The Coast Guard agrees. By requiring training in protocols outlined in ASTM F1779 – 08, including NOAA’s ‘‘Open Water Oil Identification Job Aid for Aerial Observation’’ and ‘‘Characteristic Coastal Habitats,’’ aerial observers should be prepared to fulfill all three roles. See 155.1050(l)(2)(iii).”

EDAC Settings in the DMP2 • The Dispersant-to-Oil Ratio (DOR) is 1:20. • Five gallons of dispersant will be applied to each acre (46.8 liters/hectare). • The oil slick to be treated is 4 nautical miles (7.4 km) long in the direction of spraying. • Aircraft platforms have 12 hours of time available for Tier 2 and Tier 3. • Aircraft platforms will be allowed to apply dispersants in both directions. • Check-in time of 10 minutes with spotter aircraft occurs at the beginning of each sortie. Spotter aircraft are assumed on- scene waiting for dispersant spray aircraft.

Planning and Requirement Summary Effective September 30, 2009, the Coast Guard's rules for facility and vessel owner plan holders will require dispersant capability. ( Vessel CAPS compliance – Feb 2011) To demonstrate this capability, planholders will need to make manual calculations of EDAC for each dispersant application platform they intend to use, or use DMP2.
