921.21 ACCIDENTAL DISCHARGES.
   (a)    Users shall notify the Chief, I.P.P. immediately upon the occurrences of a slugload or accidental discharge of wastes in violation of this Chapter to enable countermeasures to be taken to minimize damage to the sewage works and the receiving waters.
   (b)    This notification shall be followed, within five (5) days of the date of occurrence, by a detailed written statement describing the causes of the accidental discharge and the measures being taken to prevent future occurrences.
   (c)    Such notification shall not relieve the user of liability for any expenses, loss or damage to the sewer system, treatment plant, or treatment process, or for any fines imposed on the City on account thereof.
   (d)    In order that employees of users be informed of City requirements, users shall make available to their employees copies of this Chapter together with such other wastewater information and notices which may be furnished by the City from time to time directed toward more effective water pollution control. A notice shall be furnished and permanently posted on the user's bulletin board advising employees whom to call in case of an accidental discharge in violation of this Chapter.
   (e)    Any direct or indirect connection or entry point in a user's system where deleterious or prohibited wastes could potentially enter the sanitary sewer system shall be eliminated. However, if in the judgment of the Engineer, it is impractical to eliminate said connection or entry point, the user shall appropriately label such points to warn against the discharge of such wastes.
