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

REQUIRED RESPONSE RESOURCES FOR VESSEL RESPONSE PLANS

Using DMP2

The DMP2 software includes a link to detailed

• documentation. In addition, the download

includes sample exercises that guide the user in the use of this software.

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

• bservers 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.
