(1) Any user which has any unusual discharge that could cause problems to the POTW must immediately notify the Public Works Director by telephone of the incident. This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user to control and curtail the discharge. Such discharges may include spills, slug loads, accidental discharges, or other discharges of a nonroutine, episodic nature. Problems to the POTW which require reporting under this section include violating pretreatment prohibitions, treatment standards, or other requirements of PMC 13.90.050 through 13.90.140 such as vapor toxicity and explosivity limits.

(2) Within five days following such discharge, the user shall submit a detailed written report describing the cause(s) of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW, natural resources, or any other damage to person or property; nor shall such notification relieve the user of any fines, penalties, or other liability which may be imposed pursuant to this chapter.

(3) Regardless of whether the user has been required to submit a slug discharge control plan (per PMC 13.90.170), all users shall post notice in a prominent location advising employees whom to call at the POTW to inform the Public Works Director of a potential problem discharge (subsection (1) of this section). Users shall provide that all employees who may cause or witness such a discharge are advised of the emergency notification procedures.

(4) All users must immediately notify the Public Works Director of any changes at their facility which might increase their potential for a slug discharge. This includes increasing the volume of materials stored or located on site which, if discharged to the POTW, would cause problems. Users required to prepare a slug discharge control plan under PMC 13.90.170 shall also modify their plans to include the new conditions prior to or immediately after making such changes.
