• 4. Till fertilizers into the soil rather than dumping or broadcasting onto the surface.Determine the proper <br /> fertilizer application for the types of soil and vegetation encountered. <br /> 5. Till a topsoil mix or composted organic material into the soil to create a well-mixed transition layer that <br /> encourages deeper root systems and drought-resistant plants. <br /> 6.Use manual and/or mechanical methods of vegetation removal rather than applying herbicides,where <br /> practical. <br /> Required BMPs for the Use of Pesticides <br /> 1. Develop and implement an IPM plan(see information on integrated pest management below) and use <br /> pesticides only as a last resort. <br /> 2. Implement a pesticide-use plan and include at a minimum: a list of selected pesticides and their specific <br /> uses;brands, formulations, application methods, and quantities to be used; equipment use and <br /> maintenance procedures; safety, storage, and disposal methods; and monitoring,record keeping, and <br /> public notice procedures. All procedures shall conform to the requirements of Chapter 17.21 Revised <br /> Code of Washington(RCW)and Chapter 16-228 WAC. <br /> 3. Choose the least toxic pesticide available that is capable of reducing the infestation to acceptable levels. <br /> The pesticide should readily degrade in the environment and/or have properties that strongly bind it to the <br /> soil.Any pest control used should be conducted at the life stage when the pest is most vulnerable.For <br /> example, if it is necessary to use a Bacillus thuringiensis application to control tent caterpillars,it must be <br /> applied before the caterpillars cocoon or it will be ineffective.Any method used should be site-specific <br /> and not used wholesale over a wide area. <br /> 4.Apply the pesticide according to label directions.Under no conditions shall pesticides be applied in <br /> quantities that exceed manufacturer's instructions. <br /> 5.Mix the pesticides and clean the application equipment in an area where accidental spills will not enter <br /> surface or groundwater, and will not contaminate the soil. <br /> 6. Store pesticides in enclosed areas or in covered impervious containment. Ensure that pesticide <br /> contaminated stormwater or spills/leaks of pesticides are not discharged to storm drains. Do not hose <br /> down paved areas to a storm drain or conveyance ditch. Store and maintain appropriate spill cleanup <br /> 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 are kept in <br /> 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 streams, <br /> sloughs, and any drainage ditch or channel that leads to open water, except when approved by Ecology or <br /> by the City. All sensitive areas including wells, creeks, and wetlands 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 prior to the <br /> application. <br />
