Panera Bread Stormwater Management Report Everett,WA <br /> Suggested BMPs <br /> 1.Avoid the activity when rain is occurring or expected. <br /> 2. If possible, portable asphalt mixing equipment should be covered by an awning, a lean-to, or <br /> another simple structure to avoid contact with rain. See BMP S.4 in Chapter 4 for further details <br /> on cover structures. <br /> 3. Recycle broken concrete and asphalt. Look under Recycling Services in the Yellow Pages of <br /> the phone book to find the nearest recycler. <br /> 3.6: Landscaping and Vegetation Management Activities, Including Vegetation Removal, <br /> Herbicide and Insecticide Application, Fertilizer Application, Irrigation,Watering, <br /> Gardening,and Lawn Care <br /> Description of Pollutant Sources: Landscaping can include grading, soil transfer, vegetation <br /> removal, pesticide and fertilizer application, and watering. Stormwater contaminants include <br /> toxic organic compounds, heavy metals, oils, total suspended solids, coliform bacteria, <br /> fertilizers, and pesticides. <br /> Lawn and vegetation management can include control of objectionable weeds, insects, mold, <br /> bacteria, and other pests with chemical pesticides and is conducted commercially at <br /> commercial, industrial, and residential sites. Examples include weed control on golf course <br /> lawns, access roads, and utility corridors and during landscaping; sap stain and insect control on <br /> lumber and logs; rooftop moss removal; killing nuisance rodents;fungicide application to patio <br /> decks; and residential lawn/plant care.Toxic pesticides such as pentachlorophenol, carbamates, <br /> and organometallics can be released to the environment by leaching and dripping from treated <br /> parts, container leaks, product misuse, and outside storage of pesticide contaminated materials <br /> and equipment. Poor management of the vegetation and poor application of pesticides or <br /> fertilizers can cause appreciable stormwater contamination. <br /> Pollutant Control Approach: Control of fertilizer and pesticide applications, soil erosion, and <br /> site debris to prevent contamination of stormwater. <br /> Develop and implement an integrated pest management plan and use pesticides only as a last <br /> resort. Refer to Appendix D for an example. If pesticides/herbicides are used they must be <br /> carefully applied in accordance with label instructions on U.S. EPA registered materials. <br /> Maintain appropriate vegetation, with proper fertilizer application where practicable,to control <br /> erosion and the discharge of stormwater pollutants. Where practicable, grow plant species <br /> appropriate for the site, or adjust the soil properties of the subject site to grow desired plant <br /> species. <br /> Required BMPs for Landscaping <br /> 1. Do not dispose of collected vegetation into waterways or stormwater drainage systems. <br /> 2. Use mulch or other erosion control measures when soils are exposed for more than 1 week <br /> during the dry season or 2 days during the rainy season. <br /> Core States Group Page 30 <br />
