Panera Bread Stormwater Management Report Everett,WA <br /> 6. Store pesticides in enclosed areas or in covered impervious containment. Ensure that <br /> pesticide contaminated stormwater or spills/leaks of pesticides are not discharged to storm <br /> drains. Do not hose down paved areas to a storm drain or conveyance ditch. Store and maintain <br /> appropriate spill cleanup materials in a location known to all near the storage area. <br /> 7. Cleanup any spilled pesticides and ensure that the pesticide contaminated waste materials <br /> are kept in designated covered and contained areas. <br /> 8.The pesticide application equipment must be capable of immediate shutoff in the event of an <br /> emergency. <br /> 9. Do not spray pesticides within 100 feet of open waters including wetlands; ponds; and <br /> streams, sloughs, and any drainage ditch or channel that leads to open water, except when <br /> approved by Ecology or by the City.All sensitive areas including wells, creeks, and wetlands <br /> must be flagged prior to spraying. <br /> 10. As required by the City or by Ecology, complete public posting of the area to be sprayed <br /> prior to the application. <br /> 11. Spray applications should only be conducted during weather conditions as specified in the <br /> 4label direction and applicable local and state regulations. Do not apply during rain or <br /> immediately before expected rain. <br /> Suggested BMPs for the Use of Pesticides <br /> 1. Consider alternatives to the use of pesticides such as covering or harvesting weeds, <br /> substitute vegetative growth, and manual weed control/moss removal. <br /> 2. Consider the use of soil amendments, such as compost,that are known to control some <br /> common diseases in plants, such as Pythium root rot, ashy stem blight, and parasitic <br /> nematodes.The following are three possible mechanisms for disease control by compost <br /> addition (USEPA publication 530-F-9-044): <br /> a.Successful competition for nutrients by antibiotic production <br /> b. Successful predation against pathogens by beneficial microorganism; and <br /> c.Activation of disease-resistant genes in plants by composts. <br /> Note:Installing an amended soil/landscape system can preserve both the plant system and the <br /> soil system more effectively. This type of approach provides a soil/landscape system with <br /> adequate depth, permeability, and organic matter to sustain itself and continue working as an <br /> effective storm water infiltration system and a sustainable nutrient cycle. <br /> 3. Once a pesticide is applied, its effectiveness should be evaluated for possible improvement. <br /> Records should be kept showing the applicability and inapplicability of the pesticides <br /> considered. <br /> 4.An annual evaluation procedure should be developed including a review of the effectiveness <br /> of pesticide applications, impact on buffers and sensitive areas (including potable wells), public <br /> concerns, and recent toxicological information on pesticides used/proposed for use.
