All GPS collection was done following NJDEP GPS Data Collection Standards. The GPS data was processed and checked by NJDEP using Trimble Navigation Pfinder GPS processing software, and Arc/Info GIS. GPS base data used to perform differential corrections on the GPS data was collected by NJDEP with its base station in Trenton. The dataset was built in Arc/Info GIS by appending datasets into a final regional dataset. In decreasing order of accuracy, the other locations were derived from digitizing the locations as shown on site plans, copies of topoquads and other maps, and/or address matching. As the outfalls are GPSed, these other points will be replaced with the more accurate locations.
Data was updated with the addition of the SWID and PREFIX attribute fields. New sites were also added. Some locational coordinates were updated and some entries were updated for Statcode, Ptermdates and other fields as deemed necessary due to input received from staff and permitees/consultants.
Data was updated along with the addition of the PI_NUMBER attribute and the removal of the PCAT attribute.
Data was updated to add new sites, some locational coordinates were updated and some entries were updated for Statcode, Ptermdates and other fields as deemed necessary due to input received from staff and permitees/consultants.
Update included basic corrections in data, and the addition of new discharge points, most of which were under the B4B, BGR, and CG general permit discharge categories.
Update included basic corrections in data.
Updates included basic changes such as corrections to facility names, outfall designations and locations, changes to status codes, corrections to coordinates of outfalls, corrections to NJPDES numbers and prefixes, additions of SI and PI numbers, and changes to discharge types. Outfalls that have been transferred to the Bureau of NonPoint Pollution Control and are no longer under the jurisdiction of the Bureau of Surface Water Permitting have been removed from the layer and archived. Combine Sewer Overflow (CSO) outfalls have also been removed from the layer and archived. A new attribute called “DISCHTYPE” has replaced the existing “DISTYPE” and a new attribute called “DISCHCLASS” has been added along with the relevant values of “Major” and “Minor”. The attribute values of IMI, IMJ, MMI, MMJ, and CSO have been removed from the layer. The attribute called “PSPREG” has been removed from the layer as it is no longer relevant. For the attribute of “STATCODE”, the values of A, C, and W have been removed.
Updates included basic changes such as corrections to facility names, outfall designations and locations, changes to status codes, corrections to coordinates of outfalls, corrections to NJPDES numbers and prefixes, additions of SI and PI numbers, and changes to discharge types.
Updates included 10 additional features and basic changes such as corrections to facility names, outfall designations and locations, changes to status codes, corrections to coordinates of outfalls, corrections to NJPDES numbers and prefixes, additions of SI and PI numbers, and changes to discharge types.
Updates included 15 additional features and basic changes such as corrections to facility names, outfall designations and locations, changes to status codes, corrections to coordinates of outfalls, corrections to NJPDES numbers and prefixes, additions of SI and PI numbers, and changes to discharge types.
Updates included 53 additional features, 1 removed, and basic changes such as corrections to facility names, outfall designations and locations, changes to status codes, corrections to coordinates of outfalls, corrections to NJPDES numbers and prefixes, additions of SI and PI numbers, and changes to discharge types.
Note: Attribute headings may be truncated in Shapefile format. Additionally, the attribute OBJECTID is changed to FID in the Shapefile format.
