ACCELL CLEAN® DWD 2.0

(6) PRODUCT STORAGE [§ 300.915(a)(6)]
1. Maximum storage temperature (e.g., ^oF and/or ^oC): 130^oF
2. Minimum storage temperature (e.g., ^oF and/or ^oC): 15^oF
3. Optimum storage temperature (e.g., ^oF and/or ^oC): 30^oF to 120^oF
4. Humidity (e.g., g/kg): Relative humidity will have no impact on a sealed container of the product.
Optimal humidity for chemical storage is between 30% to 95% relative humidity. Relative humidity would only have an effect on the product if the liquid were exposed to the environment for more than 12 hours.

• Maximum humidity: should not exceed 95%
• Minimum humidity: should not be lower than 15%
• Optimal humidity: 75%

5. Other relevant conditions for product storage: The ambient air temperature around the liquid has little effect on the product unless the liquid reaches these minimum or maximum temperatures beyond 12 consecutive hours.
6. Description of the consequences to performance if product is not stored within these limits: If the product were exposed to extreme heat (above 150^oF) or extreme cold (below -20^oF) the product may exhibit phase separation. In some cases, the product can be reblended or re-agitated to re-establish a homogeneous solution. Advanced BioCatalytics can provide technical support in such an extreme instance to advise and assist on product performance evaluation and the re-blending process if deemed feasible.

(10) RECOMMENDED PRODUCT USE PROCEDURES [§ 300.915(a)(10)]

1. Application Method:

• Aerial application: Aircrafts provide the most rapid method of applying dispersants to an oil spill and a variety of aircraft can be used for spraying. For aerial spraying, Accell Clean^® DWD 2.0 is applied undiluted. Typically, application altitudes of 30 to 50 feet are recommended, although higher the altitudes may be effective under certain conditions. Actual effective altitudes will depend on the application equipment, weather, and aircraft. Careful selection of spray nozzles is critical to achieve the desired dose levels, since the droplet size must be controlled. A quarter-inch open pipe may be all that is necessary if the aircraft travels at 120 mph (104 knots) or, more, since the air shear at these speeds will be sufficient to break the dispersant into the proper sized droplets. Agricultural spray delivery systems may not be suitable because too fine spray and too little delivery of Accell Clean^® DWD 2.0 to affected area. Companies that are considering the use for this product from aircraft or vessels should consult the American Petroleum Institute’s Technical Report 1148, Aerial and Vessel Dispersant Preparedness; and for subsea use, American Petroleum Institute's Technical Report 4791, Industry Guidelines on Requesting Regulatory Concurrence for Subsea dispersant Use, which both describe the process and application of dispersants in a marine environment.
• Boat application: Accell Clean^® DWD 2.0 may also be applied from boats equipped with spray booms mounted ahead of the bow wake or as far forward as possible. The most effective method of application from a boat is to apply Accell Clean^® DWD 2.0 using a low-volume, low-pressure pump so Accell Clean^® DWD 2.0 can be applied undiluted. Accell Clean^® DWD 2.0 should not be fogged or atomized. Natural wave or boat wake action usually provides adequate mixing energy to disperse the oil. Application at sub-freezing temperatures may require a larger nozzle, supply lines, and orifices due to higher product viscosity.
• Subsea application: Accell Clean^® DWD 2.0 may also be applied subsurface at the well head using submarine equipment.

2. Concentration / Application Rate: A treatment rate of about 5 gallons per acre, or a dispersant to oil ratio of 1:20 is optimal for aerial or vessel application, however, application rates of 1:10-1:50 can be used based on the type of oil, degree of weathering, temperatures, and thickness of the slick. For subsurface application a 1:100 dispersant to oil ratio use has been proven to be an effective ratio.
3. Conditions for Use: Accell Clean^® DWD 2.0 can be used in salt water, brackish waters, open ocean or subsurface ocean waters with limitations as specified by the Federal On-Scene Coordinator in consultation with the NOAA Scientific Support Coordinator.
