COR-030000 Stormwater Management Plan <br />7. SWMI' REQUIREMENTS (§I.D.S) i <br />a) SWMP Implementation (§I.D.S.a): <br />The SWMP will be implemented prior to commencement of earth-disturbing activities. The <br />SWMP will be kept accurate and up-to-date, and will reflect the actual on site ground <br />conditions. Only changes in site conditions that require new or modified BMPs need to be <br />addressed in the SWMP. <br />b) SWMP Retention (§I.D.S.b): <br />A copy of the SWMP must be retained on site unless another location, specified by the <br />permittee, is approved by the Division (§I.D.10). <br />c) SWMP Revisions (§I.D.S.c): <br />The SWMP will be revised: <br />1) When there is a change in design, construction, operation, or maintenance of the site, <br />which would require the implementation of new or revised BMPs; or <br />2) If the SWMP proves to be ineffective in achieving the general objectives of <br />controlling pollutants in storinwater discharges associated with earth-disturbing • <br />activity; or <br />3) When BMPs are no longer necessary and are removed. <br />SWMP changes will be made prior to changes in the site conditions, except as noted below <br />under "responsive SWMP changes." SWMP revisions may include, but are not limited to: <br />potential pollutant source identification; selection of appropriate BMPs for site conditions; <br />BMP maintenance procedures; and interim and final stabilization practices. <br />The SWMP changes may include a schedule for further BMP design and implementation, <br />provided that, if any interim BMPs are needed to comply with the permit, they are also <br />included in the SWMP and implemented during the interim period. <br />d) Responsive SWMP Changes (§I.D.S.d): <br />The majority of SWMP revisions to address changing site conditions can be made <br />immediately with simple field revisions to the SWMP. In the less common scenario where <br />more complex development of materials to modify the SWMP is necessary, SWMP revisions <br />will be made in accordance with the following requirements: <br />• <br />Denison Mines (USA) Corp.
