Protocol established for assigning coordinates to effluent discharge
| Satellite imagery revealed . | Coordinates were assigned . |
|---|---|
| A visible effluent discharge pipe | To the pipe location |
| Chlorination pond | Selected 25 meters (m) from the shoreline closest to the pond in the waterway. For small streams (<50 m wide), the center of the stream was selected |
| No visible chlorination ponds or UV structures | The settling tanks were used as the point of reference to measure 25 m out from the shoreline closest to the tanks to select the point in the water. For small streams (<50 m wide), the center of the stream was selected |
| More than one waterbody was near the WWTP | The closest body of water was selected |
| Satellite resolution was poor | The discharge was assigned to the largest waterbody within 1.61 km (1 mile) of the plant |
| More than one waterbody equidistant from the WWTP | The discharge was assigned to the largest waterbody within 1.61 km (1 mile) of the plant |
