COR-040000 Stormwater Management Plan <br />0 5. COMPREHENSIVE INSPECTIONS (COR-040000, §I.B.5 AND §I.D.5): <br />Denison will conduct comprehensive inspections at least twice a year (spring and fall) in <br />accordance with the requirements of the general permit in order to ensure that the facility is <br />complying with the requirements and guidelines prescribed in the SWMP and that the SWMP <br />reflects current conditions and operations at the facility. The Comprehensive Inspections will be <br />conducted by qualified personnel possessing the knowledge and skills to assess conditions and <br />activities that could impact stormwater quality at the facility and who can evaluate the <br />effectiveness of BMPs selected. These qualified personnel will be selected by the SWMP <br />Administrator. <br />a) Active Mining Operations <br />In addition to the inspections required by the preventive maintenance program in Section 4.c, <br />qualified personnel identified by the SWMP Administrator will make a thorough inspection <br />of the stormwater management system at the Van 4 Shaft site, at least twice per year (spring <br />and fall). Where semi-annual site inspections are shown in the plan to be impracticable <br />because an employee is not stationed at or does not routinely visit the site, inspections will be <br />conducted at appropriate intervals that will be specified in this Plan, but never less than once <br />in two years. These inspections will be documented and summarized in the Annual Report <br />(see Section 8). <br />• b) Inactive Mining Operations <br />If the Van 4 Shaft becomes inactive, then the following inspection procedures will apply: <br />Qualified personnel identified by the SWMP Administrator will make a thorough inspection <br />of the stormwater management system at the Van 4 Shaft site, at least once per year. Where <br />annual inspections are shown in the plan to be impracticable, because an employee is not <br />stationed at or does not routinely visit the site, an inspection will be conducted at least once <br />every three years by a Registered Professional Engineer. The inspector will certify that the <br />site is in compliance with the plan. If the site is not in compliance with the plan, it will be <br />brought into compliance, reinspected, and plan compliance then certified by the inspector. <br />These inspections will be documented and summarized in the Compliance Report (see <br />Section 8). <br />c) Inspection Requirements for All Operations <br />Inspections for active and inactive mining operations will include the following: <br />1) Disturbed areas, areas used for material storage or handling that are exposed to <br />precipitation, and other potential sources of pollution identified in this plan will be <br />inspected for evidence of, or the potential for, pollutants entering the drainage system. <br />Erosion and sediment control measures and other structural pollution prevention <br />• measures identified in this plan will be observed to ensure that they are operating <br />correctly. <br />Van 4 Shaft SWMP 16 Denison Mines (USA) Corp.
