(1)   Large existing facilities. Existing in-ground or above-ground septage storage facilities constructed before September, 1987 and with a capacity of greater than 25,000 gallons shall be allowed as long as they meet the provisions of ch. NR 110 , the department has accepted in writing the plans and specifications and the storage facility has received a specific WPDES permit. Storage facilities installed under ch. SPS 383 are allowed if the owner obtains a specific WPDES permit.

(2)   New large facilities. No person may construct any septage storage facility, which singly or when added together, provides capacity equal to or greater than 25,000 gallons without first obtaining department plan and specification approval. All storage facilities shall be designed in accordance with the appropriate requirements of ch. NR 110 . No storage facility with a capacity equal to or greater than 25,000 gallons may operate until a specific WPDES permit is issued and an inspection and adequacy of sealing report is submitted and accepted by the department.
