• If using self-installed washout facilities, verify plastic liners are intact and sidewalls are not damaged. • If using prefabricated containers, check for leaks. • Washout facilities shall be maintained to provide adequate holdin capacity with a minimum freeboard of 12 inches. • Washout facilities must be cleaned or new facilities must be constructed and ready for use once the washout is 75% full. • If the washout is nearing capacity, vacuum and dispose of the waste material in an approved manner. • Do not discharge liquid or slurry to waterways, storm drains or directly onto ground. • Do not use sanitary sewer without local approval. • Place a secure,non-collapsing, non-water collecting cover over the concrete washout facility prior to predicted wet weather to prevent accumulation and overflow of precipitation. • Remove and dispose of hardened concrete and return the structure to a functional condition. Concrete may be reused on-site or hauled away for disposal or recycling. • When you remove materials from the self-installed concrete washout, build a new structure; or, if the previous structure is still intact, inspect for signs of weakening or damage, and make any necessary repairs. Re-line the structure with new plastic after each cleaning.
