4-2 SOURCE CONTROL BMP SPECIFICATIONS In this section,details and specifications are given for two different types of source controls-those appropriate for construction sites and those for other urban land uses,such as businesses. The City may require any source control BMPs which are appropriate for a particular business or construction site. The construction site source control BMPs are organized by the activities found in the 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 control 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. 4-2.1 CONSTRUCTION SITE SOURCE CONTROL BMPS ` 1 BMP C1.10 PESTICIDE CONTROL The "pesticide" includes herbicides and rodenticides as well as those chemicals used to control insect populat Pesticides s' . • ly be used in conjunction with Integrated Pest Management(see BMP S1.90).
