MHB_BeachWastewaterOutfalls is a subset of WASTEWATER_OUTFALLS created for the Maine Healthy Beach Program. It contains the locations of the ends of active outfall pipes and the locations of the ends of active Combined Sewer Overflow (CSO), associated with the treatment facilities licensed under the National Pollution Discharge Elimination System (NPDES) that occur near beaches on the Maine coast. WASTEWATER_OUTFALLS data was collected under two separate contracts and was overseen by the Maine Department of Environmental Protection (MEDEP). Part 1 was from 1998 to 1999 under a Geo-graphics contract and Part 2 was from 2000 to 2001 under a contract with Northern Ecological Associates. The list of NPDES facilities was taken from sites within the EPA's Permit Compliance System (PCS) database with "active outfalls". Data was gathered at facilities that were known to be active as of June 2000. All data was collected using Trimble Pro-XR GPS receivers that have corrected accuracy of +/- 1 meter.

Throughout the course of Mapping Working Waters interviews, data was collected about various place names in the marine environment. This information is presented as an un-aggregated data layer – if we heard somebody apply a name to a certain piece of bottom, we added it to the data layer. Place names identified represent either features on the ocean bottom (Death Trap, New Bank), features on nautical charts or GPS plotters (Hot Dog Shoal, Gull Wing), or landmarks used for line-of-sight navigation (House in the notch) . It is worth highlighting that there are more than one area referred to as “pasture” and “rolling eighties” so depending on where along the coast you are or what fishery you are talking about, they refer to very different parts of the bottom. Place names are not only useful for navigation and referencing marine areas, but also in preserving traditional knowledge seascapes of and historical stewardship of marine areas.
