COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT, Water Quality Control Division <br />Rationale, Page 8, COG-0500000 Sand and Gravel General Permit <br />b) Description of Potential Pollutant Sources/Material Inventory <br />c) Stormwater Quality Controls <br />1) SWMP Administrator <br />2) Materials handling and spill prevention <br />3) Erosion and sediment controls <br />4) Other pollution prevention measures <br />5) Preventive maintenance <br />6) Good housekeeping <br />7) Identification of discharges other than stormwater. <br />2. Other Requirements <br />a) Facility Inspections: The permittee will be required to make a thorough inspection of their stormwater management <br />system, at least twice per year (in the spring and fall). (See Part LD.4 of the permit for alternate schedules.) These <br />inspections must be documented and summarized in the Annual Report to the Division. <br />b) Employee Education: The permittee shall develop and implement employee education programs to inform personnel at <br />all levels of responsibility of the components and goals of the SWMP. This section has been expanded; from the previous <br />permit to include contractor and temporary personnel, in keeping with other stormwater permits. <br />E. Stormwater Management Plan (SWMP) <br />The SWMP Contents section has been modified. Some of the changes are limited to organization of information, which does not <br />require modification of an existing permittee's current SWMP. Most of the SWMP changes involve clarifications, reformatting, or <br />adopting requirements from the Division's Stormwater Construction general permit (e.g., BMP installation specifications). For <br />existing permittees (i. e., those with permit coverage prior to the reissuance date of this permit), their SMWP must be amended to <br />include the new required items: <br />For existing permittees, any SWMP changes based on the change in permit requirements must be completed within 5 months of the <br />effective date of the certification. The plan is not to be submitted to the Division unless requested, but must be available on site as <br />outlined in Part LD.5(b) of the permit. <br />1. Terms and Conditions, General Limitations and Design Standards: This section reiterates the requirement that facilities <br />select, install, implement, and maintain appropriate BMPs, following good engineering, hydrologic and pollution control <br />practices. In addition, requirements to adequately design BMPs to prevent pollution or degradation of State waters (see Part <br />LD.2 of the permit) have been revised and are discussed below. <br />2. Site Map: The list of items needed for the Site Map has been expanded, in order to adequately characterize the site. A list of <br />items and factors has been added to the section on identifying potential stormwater pollutants, in order to clarify the <br />Division's intent in this area. This requirement may necessitate changes to existing permittees' SWMPs. <br />3. Description of Potential Pollutant Sources: The requirement to identify Potential Pollutant Sources has been expanded to <br />include more details for the evaluation of such sources. This evaluation allows for the appropriate selection of BMPs for <br />implementation at a facility or site. This requirement may necessitate changes to existing permittep' SWMPs. <br />4. Stormwater Management Controls: See Part I.C.1 of the permit. <br />a) This section has been modified to require identification of a SWMP Administrator. The SWMP Administrator is a specific <br />individual(s), position or title who is responsible for the process of developing, implementing, maintaining, and revising <br />the SWMP. This individual serves as the comprehensive point of contact for all aspects of the facility's SWMP. This <br />requirement may necessitate changes to existing permittees I SWMft <br />b) Sections have been added requiring that preventive maintenance and good housekeeping measures be included in the <br />SWMP. Preventive maintenance is critical to ensuring the success of the BMPs at a site. Good housekeeping measures <br />are a common sense means of increasing compliance. This requirement may necessitate changes to existing permittees' <br />SWMP& <br />5. Permit Termination: A section has been added on additional SWMP items for sites seeking perriiit termination. This section <br />provides more guidance to permittees than has been available in the past, on the steps needed to inactivate a site's permit
