PART I <br /> Permit No.: COR400000 <br /> (27) Significant Materials - Include, but not limited to, raw materials; fuels; materials such as solvents, <br /> detergents, and plastic pellets; finished materials such as metallic products; raw materials used in <br /> food processing or production; hazardous substances designated under section 101(14) of CERCLA; <br /> any chemical the permittee is required to report under section 313 of Title III of the Superfund <br /> Amendments and Reauthorization Act (SARA); fertilizers; pesticides; and waste products such as <br /> ashes, stag and sludge that have the potential to be released with stormwater discharges. <br /> (28) Small Construction Activity - The discharge of stormwater from construction activities that result in <br /> land disturbance of equal to, or greater than, one acre and less than five acres. Small construction <br /> activity also includes the disturbance of less than one acre of total land area that is part of a larger <br /> common plan of development or sale, if the larger common plan ultimately disturbs equal to, or <br /> greater than, one acre and less than five acres. <br /> (29) Spill - An unintentional release of solid or liquid material which may pollute state waters. <br /> (30) State Waters - means any and all surface and subsurface waters which are contained in or flow in <br /> or through this state, but does not include waters in sewage systems, waters in treatment works of <br /> disposal systems, waters in potable water distribution systems, and all water withdrawn for use <br /> until use and treatment have been completed. <br /> (31) Steep Slopes: where a local government, or industry technical manual (e.g., stormwater BMP <br /> manual) has defined what is to be considered a "steep slope", this permit's definition <br /> automatically adopts that definition. Where no such definition exists, steep slopes are <br /> automatically defined as those that are 3:1 or greater. <br /> (32) Stormwater - Precipitation runoff, snow melt runoff, and surface runoff and drainage. See 5 CCR <br /> 1002-61.2(103). <br /> (33) Total Maximum Daily Loads (TMDLs) -The sum of the individual wasteload allocations (WLA) for <br /> point sources and load allocations (LA) for nonpoint sources and natural background. For the <br /> purposes of this permit, a TMDL is a calculation of the maximum amount of a pollutant that a <br /> waterbody can receive and still meet water quality standards, and an allocation of that amount to <br /> the pollutant's sources. A TMDL includes WLAs, LAs, and must include a margin of safety (MOS), and <br /> account for seasonal variations. See section 303(d) of the CWA and 40 C.F.R. 130.2 and 130.7. <br /> (34) Upset - an exceptional incident in which there is unintentional and temporary noncompliance with <br /> permit effluent limitations because of factors beyond the reasonable control of the permittee. An <br /> upset does not include noncompliance to the extent caused by operational error, improperly <br /> designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, <br /> or careless or improper operation in accordance with 40 CFR 122.41(n) and Regulation 61.2(114). <br /> F. MONITORING <br /> The division may require sampling and testing, on a case-by-case basis. If the division requires <br /> sampling and testing, the division will send a notification to the permittee. Reporting <br /> procedures for any monitoring data collected will be included in the notification. <br /> If monitoring is required, the following applies: <br /> 1. the thirty (30) day average must be determined by the arithmetic mean of all samples <br /> collected during a thirty (30) consecutive-day period; and <br /> 2. a grab sample, for monitoring requirements, is a single "dip and take" sample. <br /> Page 20 of 33 <br />
