Therefore, proper and careful <br />development and implementation of the plan will maximize the potential benefits of pollution <br />prevention and sediment and erosion control measures. Your permit consists of specific <br />requirements for the plan, including deadlines and certain storm water control measures. This <br />Chapter provides a step-by-step explanation of how to develop and implement your Storm Water <br />Pollution Prevention Plan. <br /> <br />The process of developing and implementing a Storm Water Pollution Prevention Plan for <br />construction activities has been divided into six phases which are indicated in Figure 2.1. These <br />phases are: <br /> <br />1. Site Evaluation and Design Development <br />2. Assessment <br />3. Control Selection/Plan Design <br />4. Certification/Notification <br />5. Construction/Implementation <br />6. Final StabilizationlTermination. <br /> <br />The following sections describe the processes involved in each of the phases listed above. The <br />pollution prevention plan is developed during the first three phases listed above. <br /> <br />Your NPDES storm water permit may specify deadlines for plan development and implementation. <br />The sequence in Figure 2.1 assumes that pollution prevention plans will be completed and <br />implemented at the time the project breaks ground and revised (if necessary) as construction <br />proceeds. Your plan should be in place before project initiation because construction operations <br />pose environmental risks as soon as activity begins. The initial rough grading activities may <br />contribute a significant amount of pollutants to storm water runoff. Be sure to read your permit <br />closely to see what dates and deadlines apply to your site. <br /> <br />The planning for pollution prevention measures should be done while you develop the site <br />construction plan. The best Storm Water Pollution Prevention Plans are developed at the same <br />time as the design of the site plan. However, if you have completed your site plan design before <br />you begin to prepare the Storm Water Pollution Prevention Plan it is not necessary to start the <br />process all over again. Much of the information needed for the plan should already be included in <br />vour design documents. A Storm Water Pollution Prevention Plan can be prepared for most <br />construction projects by using information from the existing design, and modifying the design to <br />accommodate the controls. <br /> <br />Responsibility for developing a Storm Water Pollution Prevention Plan typically lies with the owner <br />of the property that is being developed, or with the owner and operator (e.g., General Contractor) <br />of the construction project. <br /> <br />September 1992 <br /> <br />2-1 <br />
