2. 3.5 pounds per gallon of coating, excluding water, delivered to a coating applicator in a coating application system that utilizes air or forced air driers;

3. 3.5 pounds per gallon of coating, excluding water, delivered to a coating applicator that applies extreme performance coatings, or

4. 3.0 pounds per gallon of coating, excluding water, delivered to a coating applicator for all other coatings and coating application systems.

2. The use of detergents, high pressure water, or other non-volatile cleaning methods;

3. The minimization of the quantity of volatile organic compounds used to clean lines of equipment; and
