Part II <br /> Page 46 of 67 <br /> Permit No.COG500000 <br /> ii) Two hundred micrograms per liter(200 µg/I)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 µg/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 before <br /> the date of the bypass,to the Division. The bypass shall be subject to Division approval and limitations imposed by the Division. <br /> 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.S. <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 /> d. The permittee may allow a bypass to occur which does not cause effluent limitations to be exceeded,but only if it also <br /> is for essential maintenance or to assure optimal operation. These bypasses are not subject to the provisions of <br /> paragraph(a)above. <br /> e. The Division may approve an anticipated bypass,after considering adverse effects,if the Division determines that the <br /> bypass will meet the conditions specified in paragraph (a)above. <br /> 8. Upsets <br /> a. "Upset"means an exceptional incident in which there is unintentional and temporary noncompliance with permit <br /> effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include <br />
