<br />, <br /> <br />Irrigation Per~~!0Applications <br />.' ~tl::/ <br />00281:1 '. <br /> <br />tiW) <br /> <br />Pa ge 2 <br /> <br />,. <br /> <br />It is the individual or organization who actually has control <br />of or responsibility for the di.scharge of irrigation return flows <br />who must apply for the permit. Additionally, if an irrigated area <br />which does not fall within the criteria mentioned above is determined <br />to be a significant contributor of pollution by the state water pollution <br />control, agency or the EPA, the owner or operator must comply with the <br />NPDES filing requirements. <br /> <br /> <br />Numerical 1 imits on the amount of pollutants allowed in irrigation <br /> <br /> <br />return flows have not yet been established. The FWPCAA requires the <br /> <br /> <br />application of the best practicable control technology economically <br /> <br /> <br />achievable for irrigation return flows. <br /> <br />..-.:-.,.~ <br /> <br /> <br />~t.~f <br />'J:-;~f,~ <br />~~;:-:~. <br />~~t~?; <br />~::'2,:', <br />...."..- <br /> <br />EPA has an extensive research and demonstration program underway <br /> <br /> <br />whi ch wi 11 provi de gui dance in defi ni ng the level of di scharge. The <br /> <br /> <br />level of technology will determine the level of pollutant that could <br /> <br /> <br />reasonably be expected to be discharged using available water application <br /> <br /> <br />,methods, scheduling and other on-farm management techniques. <br /> <br />Because minimum technological and water quality requirements <br />have not been defined, it is proposed that discharge conditions <br />included in irrigation permits will initially require minimal monitoring <br />and reporting and the submittal of a plan to abate any high.levels of <br />pollutants that are identified as a result of the monitoring. <br /> <br />. <br /> <br />END <br /> <br />'$'"?'< <br />t:-&;~ <br />(<,<iff' <br /> <br />~ <br />til~;i <br /> <br />':,.-;.-;.z": <br />.........-.. <br />~._;_:;,.--; ~:~::: <br />;\tf;,' <br /> <br />"", . <br />~:~~~\~~.~o~ <br />... <br /> <br />
