That any activity has occurred or will occur which would result in the discharge, on a routine or frequent <br />basis, of any toxic pollutant which is not limited in the permit, if that discharge will exceed the highest of <br />the following "notification levels': <br />i) One hundred micrograms per liter (100 pg/l); <br />ii) Two hundred micrograms per liter (200 pg/t) for acrolein and acrylonitrile; five hundred micrograms <br />per liter (500 pg/t) for 2.4-dinitrophenol and 2-methyl-4.6-dinitrophenol; and one milligram per liter <br />(1.0 mg/l) for antimony; <br />iii) Five (5) times the maximum concentration value reported for that pollutant in the permit application <br />in accordance with Section 61.4(2)(8). <br />iv) The level established by the Division in accordance with 40 C.F.R. S 122.44(f). <br />b.

Bypass Notification <br />If the permittee knows in advance of the need for a bypass, a notice shall be submitted, at least ten (10) <br />calendar days before the date of the bypass, to the Division. The bypass shall be subject to Division approval <br />and limitations imposed by the Division. Violations of requirements imposed by the Division will constitute a <br />violation of this permit. <br />7. Bypass <br />a. "Bypass' means the intentional diversion of waste streams from any portion of a treatment facility. <br />b. Bypasses are prohibited and the Division may take enforcement action against the permittee for bypass, <br />unless: <br />i) The bypass is unavoidable to prevent loss of life, personal injury, or severe property damage; <br />ii) There were no feasible alternatives to bypass such as the use of auxiliary treatment facilities, <br />retention of untreated wastes, or maintenance during normal periods of equipment downtime. This <br />condition is not satisfied if adequate back-up equipment should have been installed in the exercise of <br />reasonable engineering judgment to prevent a bypass which occurred during normal periods of <br />equipment downtime or preventive maintenance; and <br />iii) Proper notices were submitted in compliance with the NOTIFICATION REQUIREMENTS section of this <br />permit. <br />c. "Severe property damage" as used in this Subsection means substantial physical damage to the treatment <br />facilities which causes them to become inoperable, or substantial and permanent loss of natural resources <br />
