Permit, Part II <br />Page 30 of 47 <br />Permit No. C00000213 <br />All existing manufacturing, commercial, mining, and silvicultural dischargers must notify the Division as soon as they know <br />or have reason to believe: <br />a. That any activity has occurred or will occur which would result in the discharge, on a routine or frequent basis, of any <br />toxic pollutant which is not limited in the permit, if that discharge will exceed the highest of the following "notification <br />levels": <br />i) One hundred micrograms per liter (100 µg/1); <br />ii) Two hundred micrograms per liter (200 µg/1) for acrolein and acrylonitrile; five hundred micrograms per liter (500 <br />µg/1) for 2.4-dinitrophenol and 2-methyl-4.6-dinitrophenol; and one milligram per liter (1.0 mg/1) for antimony; <br />iii) Five (5) times the maximum concentration value reported for that pollutant in the permit application in <br />accordance with Section 61.4(2)(g). <br />iv) The level established by the Division in accordance with 40 C.F.R. § 122.44(f). <br />b. That any activity has occurred or will occur which would result in any discharge, on a non -routine or infrequent basis, of <br />a toxic pollutant which is not limited in the permit, if that discharge will exceed the highest of the following <br />"notification levels": <br />i) Five hundred micrograms per liter (500 pg/1); <br />ii) One milligram per liter (1 mg/1) for antimony; and <br />iii) Ten (10) times the maximum concentration value reported for that pollutant in the permit application. <br />iv) The level established by the Division in accordance with 40 C.F.R. § 122.44(f). <br />6. Bypass Notification <br />If the permittee knows in advance of the need for a bypass, a notice shall be submitted, at least ten (10) calendar days <br />before the date of the bypass, to the Division. The bypass shall be subject to Division approval and limitations imposed by <br />the Division. Violations of requirements imposed by the Division will constitute a 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, 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, retention of <br />untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if <br />adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to <br />prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and <br />iii) Proper notices were submitted in compliance with Part II.A.5. <br />c. "Severe property damage" as used in this Subsection means substantial physical damage to the treatment facilities <br />which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably <br />be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by <br />delays in production. <br />
