VI. RECOMMENDED APPLICATION PROCEDURE
1. Application Method: COREXIT® EC9580A contains a balanced formula of specifically selected biodegradable surfactants in a de-aromatized hydrocarbon solvent system. COREXIT® EC9580A has a very low degree of toxicity to marine and shoreline organisms. Shorelines, Mangroves, and Seagrasses - COREXIT® EC9580A is sprayed directly on the oiled rocky shorelines, mangroves or seagrasses full strength as supplied. After a soak time of zero to thirty minutes, rinse the cleaner and the oil released from the shoreline surface into the water where it can be readily recovered by conventional means such as skimmers or absorbents. The soak time may vary with temperature, oil density and degree of weathering. 2. Concentration/Application Rate: The recommended dosage is approximately 1 gallon per 100 square feet but this can vary depending on the amount of weathering and oiling. The product should be applied full strength as supplied. Since it is hydrocarbon-based, the product should not be diluted with water during application as this will greatly reduce effectiveness. 3. Conditions for Use: COREXIT® EC9580A is useful on shorelines in fresh or salt water. It is effective on all types of oil including heavily weathered and emulsified oil ("chocolate mousse") containing up to 50 percent water.
