Management Program 1.0 INTRODUCTION The Department of Conservation and Recreation (DCR) is committed to maintaining the important recreational, historical and water resources available to the people of Massachusetts at DCR parks, reservations, forests, beaches, rinks, pools and parkways. DCR understands the importance of storm water to all of these facilities and the threat of pollution from storm water and erosion. To ensure that DCR is taking all measures necessary to address these threats, they have produced the following Storm Water Management Plan (SWMP) and associated Notice of Intent (NOI) to fully comply with the National Pollutant Discharge Elimination System (NPDES) Phase II General Permit for Municipal Separate Storm Sewer Systems (MS4s). The plan outlines the many existing programs currently employed by DCR to address storm water and the additional programs that will be implemented in the next three years. 1.1 Department Organization The Legislature created the Department of Conservation and Recreation (DCR) in July 2003 by merging the Metropolitan District Commission (MDC) and the Department of Environmental Management (DEM). DCR now includes four main divisions – the Division of Urban Parks and Recreation, Division of State Parks and Recreation, the Division of Water Supply and the Division of Planning and Engineering. DCR’s organizational set-up is summarized in Figure 1 DCR Organizational Chart and described below. The Division of State Parks and Recreation (DSPR) maintains nearly 300,000 acres of the state’s forests, beaches, mountains, ponds, riverbanks, trails, and parks outside of the Greater Boston area. The Division protects land and resources on privately and municipally held land through technical assistance, grant and planning programs, policy development, and other services. The Division of Urban Parks and Recreation (DUPR) has broad management responsibilities for the preservation, maintenance, and enhancement of the natural, scenic, historic, and aesthetic qualities of the environment within the Greater Boston area. The Division of Water Supply Protection (DWSP) manages and protects the drinking water supply watersheds for Greater Boston. The Division provides technical support to other state agencies, monitors lakes and ponds, dam safety, well drillers, and rainfall throughout the state. The Division is made up of two sections - the Office of Watershed Management manages and protects the drinking water supply watersheds for approximately 2.2 million residents of Massachusetts, primarily in Greater Boston. The Quabbin Reservoir, Ware River, and Wachusett Reservoir watersheds are the sources of drinking water for distribution by the Massachusetts Water Resources Authority (MWRA). The Office also manages and protects the Sudbury 1-1 July 2007 Department of Conservation and Recreation NPDES Storm Water Management Program Reservoir system, which is the reserve drinking water supply for Greater Boston. The Office of Water Resources promotes water quality and conservation through several functions. The Division of Planning and Engineering provides professional planning, engineering, design and construction management services in support of DCR’s state parks and forests, urban parks and reservations, and water supply divisions. The Department’s facilities are comprised of urban, suburban and rural open space; forests; parks; reservations; recreational facilities; waterways; parkways; water bodies; and coastlines that are managed and maintained on behalf of the public for the purposes of natural, historic, and cultural resource protection, sustainable recreation, and education. 1.2 NPDES Phase II Storm Water Regulations The U.S. Environmental
