CITY OF EVERETT STORMWATER MANAGEMENT MANUAL <br /> Required BMPs <br /> The following BMPs or equivalent measures are required of all businesses engaged in building repair, <br /> remodeling,and construction: <br /> 1. Employees must be educated about the need to control site activities to prevent stormwater <br /> pollution,and also trained in spill cleanup procedures. <br /> 2. Spill cleanup materials,appropriate to the chemicals being used on site, must be available at the <br /> work site at all times. <br /> 3. The work site must be cleaned up at the end of each workday,with materials such as solvents put <br /> away indoors or covered and secured so that vandals will not have access to them. <br /> 4. The area must be swept daily to collect loose litter,paint chips,grit,and dirt. <br /> 5. Absolutely no substance can be dumped on pavement,on the ground,or in or toward storm <br /> drains,regardless of its content,unless it is water only. <br /> 6. For wood treating activities drop cloths must be placed where space and access permit before the <br /> work begins. Additional drip pans must be used in areas where drips are likely to occur that <br /> cannot be protected with a drop cloth. <br /> 7. Ground or drop cloths must be used underneath scraping,sandblasting work. Ground cloths, <br /> buckets,or tubs must also be used anywhere that work materials are laid down. <br /> 8. Incidental cleaning of paint brushes and other tools that are covered with water-based paints must <br /> be cleaned in sinks connected to sanitary sewers or in portable containers that can subsequently <br /> be dumped into a sanitary sewer drain. Brushes and tools covered with non-water-based finishes <br /> or other materials must be cleaned in a manner that enables collection of used solvents for <br /> recycling or proper disposal and cannot be discharged to the sanitary sewer. See BMP S.2 in <br /> Chapter 4 for disposal options. <br /> 9. Storm drain covers or similarly effective devices must be used if dust,grit,washwater,or other <br /> pollutants may escape the work area. This is particularly necessary on rainy days. The cover or <br /> containment device shall be placed over the storm drain at the beginning of the workday,and <br /> accumulated dirty runoff and solids must be collected and disposed of before removing the cover <br /> at the end of the day. <br /> Suggested BMPs <br /> The following BMPs are not required, but can provide additional pollution protection: <br /> 1. Materials should be recycled whenever possible. <br /> 2. Light spraying of water on the work site can control some of the dust and grit that can blow away. <br /> Oils must never be used for dust control. Never spray to the point of runoff from the site. <br /> 3. Activities such as tool cleaning should occur over a ground cloth or within a containment device <br /> such as a tub. <br /> Volume IV—Source Control <br /> 3-40 <br />
