The plan <br />shall identify areas which, due to <br />topography, activities, or other factors, <br />have a high potential for significant soil <br />erosion, and identify structural, <br />vegetative, and/or stabilization measures <br />to be used to limit erosion. <br />(i) Management of Runoff. The plan shall <br />contain a narrative consideration of the <br />appropriatenes's of traditional storm water <br />management p=actices (practices other than <br />those which control the generation or <br />source(s)/of pollutants) used to divert, <br />infiltrate, reuse, or otherwise manage <br />storm water runoff in a manner that reduces <br />pollu ants in storm water discharges from <br />the qq~te. The plan shall provide that <br />men ~irea that the permittee determines to <br />be~easonable and appropriate shall be <br />isg~ lemented and maintained. The potential <br />of various sources at the facility to <br />contribute pollutants to storm water <br />discharges associated with industrial <br />activity (see Part I.C.4.d.(2) (description <br />of potential pollutant sources) of this <br />permit) shall be considered when <br />determining reasonable and appropriate <br />measures. Appropriate measures may <br />include: vegetative swales and practices, <br />reuse of collected storm water (such as for <br />a process or as an irrigation source), <br />inlet controls (such as oil/water <br />separators), snow management activities, <br />infiltration devices, and wet <br />detention/retention devices. <br />(4) Comprehensive Site Compliance Evaluation. <br />Qualified personnel shall conduct site <br />compliance evaluations at appropriate intervals <br />specified in the plan, but, except as provided <br />in Part I.C.4.d.(4)(d) (below), in no case less <br />than once a year. Such evaluations shall <br />provide: <br />(a) Areas contributing to a storm water <br />discharge associated with industrial <br />activity shall be visually inspected for <br />evidence of, or the potential for, <br />pollutants entering the drainage system. <br />Measures to reduce pollutant loadings shall <br />be evaluated to determine whether they are <br />adequate and properly implemented in <br />accordance with the terms of the permit or <br />
