      "description": "This feature layer, utilizing data from the U.S. Environmental Protection Agency (EPA), displays regional offices. The EPA began operation on December 2, 1970 and it inherited two regional systems from predecessor agencies. The Federal Water Quality Administration which used a nine region system and the Environmental Health Service which had adopted the ten Standard Federal Regions suggested by the Office of Management and Budget (OMB). In order to facilitate easier operations with local and state governments as well as other federal agencies the EPA chose to adopt the OMB Standard Federal Regions which still exist today.<div><br /></div><div><div><img src=\"\" /><br /></div><div><i>Regional Office locations</i></div><div><br /></div><div>For more information: <a href=\"\" target=\"_blank\">About EPA</a></div><div>For feedback, please contact: <a href=\"\" target=\"_blank\"></a></div><div><div><br /></div><div><div>EPA sites of interest<b><br /></b></div><div><b><br /></b></div><div><img src=\"\" /> <a href=\"\" target=\"_blank\">ArcGIS Online Organizational Homepage</a><b><br /></b></div><div><b><br /></b></div><div>Other Federal User Community federally focused content that may interest you</div><div><b><br /></b></div><div><img src=\"\" /> <a href=\";t=content&amp;restrict=false\" target=\"_blank\">U.S. Environmental Protection Agency</a>           <img src=\"\" /> <a href=\";sort_by=relevance\" target=\"_blank\">Open Data: U.S. EPA</a> </div></div></div></div>",
