- [stablishine iniurv levels: An injury or tolerancc level is used to detertnine if the problem is serious <br /> enough to justify somc kind of trcatment. A trade-off needs to be made betH•een the amount of damage <br /> done versus the cost of control. An injury level should be detcrmined for each potential pest,and that <br /> Ievel should be compared with fieid samples or observat'.ons before any action is taken. <br /> - Rccord-keenine: Rccords arc kept of what is scen,decisions made, actions taken, and results. <br /> - Selectin¢ least-toxic treatments: Trcatmen[strategies are chosen that are the least disruptivc of namral <br /> controls, least hazardous to human or non-target organisms health, least damaging to the general <br /> environment,the most likely to produce a pertnancnt reduction in the em�ironment's ability to support <br /> that pest,and the most cost-effectivc in the short and long tertn. The most eners,y and cost-effective pest <br /> management strategy in thc long tertn is to redesign the system to eliminate the life support systems <br /> required by thc pcsts. <br /> - Evaluation and adiustm^nt: Inspection is done after thc trcatment action has been taken to detem�ine if <br /> tlie trcatment was wonhwhile and how the whole process can be improved to achieve the overall <br /> objec.ives ef the program. <br /> Pesticides are used oniy where other techniques are not adequate or possible to use. Prcvention is a major <br /> component of IPM and can be best addressed at the program design stage. <br /> Scouting can regularly be done by work and road crews for insect and weed infestations so that carly action c�n <br /> bc taken. Prompt action against a pest before it becomes established means that less toxic methods of control, <br /> such as hand weeding, can be used instead of an herbicidc or pesticide. <br /> BMPs FOR THE• USE OF PESTiCIDCS <br /> 1. A pesticide-use plan shou►d be fomtulatcd and should include at a minimum: a list of selected pesticides <br /> and their specific uses; brands, formulations,application methods and quantities to be used; equipmcnt <br /> � use and maintenance procedures; safety, storage, and disposal mctfiods; monitoring and record keeping <br /> procedures and public notice procedures. All procedures shall confortn to the requ�rcments of Ch. 17�1 <br /> RCVI'and Cb. 16-225 WAC(see R.S in Section 4-3). <br /> �. Any control used should be donc at the life stagc when the pest is most vulnerable. Any method used <br /> should bc site-speci�c und not used wholesale ovcr a wide area. Oncc an application is made, its <br /> eflectivcness should be evaluated so that future treatment can be more finely[uned. <br /> 3. Thc pcsticide chosen shall be the least toxic pesticide available tha[ is capable of reducing the infestation <br /> to acceptable levels. The pesticide should readily degrade in the environment and/or have properties that <br /> stronglq bind it to soil particles. <br />� 4. Documented evidence shall be provided showing the inapplicability of available altematives. �I <br /> 5. An annual evaluation procedure should be developed and include a review of the effectiveness of <br /> trcatments, buffers and sensitive areas,public concems and complaints, and recent toxicological <br /> information on pesticides uscd or proposed for use. <br /> 6. Pesticides shall not be sprayed within 100 feet of open�•aters including wetlands, ponds,streams, <br /> sloughs and any drainage ditch or channel that Icads to open water. <br /> 7. If required or recmnmended by the Cit��, public posting of the area to be sprayed shall be done prior to <br /> the application. All sensitive areas including wells, creeks, and wetlands shall bc flaF�a� nrior to <br /> spraying and a buffer strip of approximately ]00 feet shall be used. <br /> 8. Spray application shall not occur during weather conditions indicated in the applicable 1rn�s. <br /> 9. Spreadedstickers used shall be tl�c Icast toxic and/or most mrget specific available. <br /> 4-2-15 <br />
