CITY OF EVERETT STORMWATER MANAGEMENT MANUAL Pollutants of concern include toxic organic compounds,oils and greases, heavy metals,nutrients, suspended solids, chemical oxygen demand(COD),and biochemical oxygen demand(BOD). Pollutant Control Approach: Store wastes in suitable containers with leak-proof lids. Sweep or shovel loose solids. Educate employees about the need to check for and replace leaking containers. Required BMPs The following BMPs are required of all businesses and public agencies engaged in storage of non- dangerous solid wastes or food wastes: 1. All solid and food wastes must be stored in suitable containers. Piling of wastes without any cover is not acceptable. 2. Storage containers must be checked for leaks and replaced if they are leaking,corroded,or otherwise deteriorating. 3. Storage containers must have leak-proof lids or be covered by some other means. Lids or covered must be kept closed at all times except when material is being placed in the storage container. This is especially important for dumpsters,as birds can pick out garbage and drop it, promoting rodent,health, and stormwater problems,OR If lids cannot be provided for the waste containers, or they cannot otherwise be covered, a designated waste storage area must be provided. The designated waste storage area shall have a containment berm, dike, or curb,and the designated area must drain to a sanitary sewer(contact the City's Industrial Pretreatment Program at(425)257-8874 prior to any connections)or holding tank for further treatment. See BMP S.7 and S.3 in Chapter 4 for more information. 4. Employees must be trained to frequently check storage containers for leaks and to ensure that the lids are on tightly. 5. The waste storage area must be swept or otherwise cleaned frequently to collect all loose solids for proper disposal in a storage container. Do not hose the area to collect or clean solids. 6. If containers are cleaned,all rinse water from cleaning must be disposed of in a sanitary sewer, process treatment, or dead-end sump with appropriate disposal at a later date. 7. Catch basins on the property that receive drainage from the waste storage area shall be cleaned out. See BMP S.9 in Chapter 4 of this volume for details on catch basin cleaning. Suggested BMPs 1. If the amount of waste accumulated frequently exceeds the capacity of the storage container,then another storage container must be obtained and utilized. 2. Store containers such that wind will not be able to knock them over. 3. Designate a storage area,pave the area,and slope the drainage to a holding tank to prevent stormwater run-on or run-off. If a holding tank is used,the contents must be pumped out before the tank is full and properly disposed of See BMP S.2 in Chapter 4 of this volume for more information on disposal options. 4. Compost appropriate wastes. Contact the City at(425)257-8800 for more information on composting. 5. Recycle solid wastes.The Industrial Materials Exchange program facilitates the transfer of excess materials and wastes to those who can use them.
