4-2 SOURCE CONTROL BMP SPECiFICATIONS In this section, details and specifications are given for hvo different types of source controls-those appropriate for construction sites and those for other urban land uses, such as businzsses. The Ciry may require any source control BMPs which are appropriate for a particular business or construction site. The construction site source control BMPs are or�anized by the activities found in !he Construction Site Activities Checklist (Table 1-4.1, Section 1-4). These BMPs are mostly presented in the form of guidelines and should be implemented on all construction sites where the described activities will occur. The urban land use source contrcl BMPs are organized by the activities found on the Land Use Activities Checklist (Table 1-4.2, Section 1-4). Specific recommendations for each business are not made since the activities for each vary widely. 42.1 CONSTRUCTION SITE SOURCE CONTROL BMIPS 4-2.1.1 BMP C1.10 Pk:STICIDE CONTROL The word "pesticide" includes herbicides and rodenticides as well as those chemicals used to control insect populations. Pesticides shall only be used in conjunction with Integrated Pest Management (see BMP S 1.90). Integrated Pest Management utilizes a needs assessment which determmes which method to use and the necessity of controlling a pest population. Pesticides should only be used after methods which are less disruptive to the environment and to human health are used first. If pesticides must be used, clearance is often required by restrictive federal anc� state regula[ions. All pesticides should be stored and applied in accordance with regulations of the State Department of Agriculture, WAC 16- 228-185. The DOE Stormwater Management Manual gives additional i:�fortnation regarding these regulations. When using pesticides, recommendations for dosages, type of application equipment, time of application, application rates, and cleaning of application equipment should be adhered to. Many pesticides are considered "Dangerous Wastes" and must be disposed of properly. Disposal of excess pesticides and pesticide-related wastes should conform to all applicable federal, state and local regulations. General disposal procedures are: - Dispose of excess pesticides and pesticide-related wastes through a licensed waste management firnt or treatment, storage and disposal company (TSD). - Use up all products, or give them away to garden centers, landscape services, etc. - Triple rinse containers before disposal and re-use rinse waters as product. Pesticide storage areas on the construction site should be protected from the elernents, from vandals, and from unauthorized personnel. Waming signs should be placed in areas recently sprayed or treated with dangerous pesticides. Other appropriate procedures are: Set aside a locked, weather-resistant storage area. Use plastic sheeting to line the storage area. Regularly monitor storage areas for leaks and repair as necessary. - Keep pesticides in a cool; dry place with a list of the products in storage. - Tightly close lids and check containers periodically for leaks or deterioration. In case of a leak, put Ihe original container into a larger container and label it properly. - Require applicTtors to follow the notification requirements of the State DeNartment of Agricul,ture. Neighbors on properties adjacent to the one being sprayeri should also be notified prior to spraying. 4-2-I
