SWPPP requirements, and the suggested order of the SWPPP elements have been rearranged (1) to correspond more closely with other storm water permits in effect throughout the country, and (2) to generally follow a more logical patty. Facility operators that have already developed and implemented SWPPPs under previous general permits are required to review the SN PPP's requirements contained in this General Permit and then review their existing SWPPP for adequacy. If the existing SWPPP adequately identifies and assesses all potential sources of pollutants and describes the appropriate BMPs necessary to reduce or prevent pollutants, the facility operator is not required to revise the existing SWPPP. One of the major elements of the SWPPP is the elimination of unauthorized non -storm water discharges to the facility's storm drain system. Unauthorized non --storm water discharges cart be generated from a wide variety of potential pollutant sources. They include waters from the rinsing or washing of vehicles, equipment, buildings, or pavement; materials that have been improperly disposed of or dumped, and spilled; or leaked Admilk materials. Unauthorized non -storm water discharges can contribute a significant pollutant load to recei.vina waters. Measures to control spills, leakage, and dumping car, often be addressed through BMPs. Unauthorized non -storm water discharges may enter the storm drain system via conveyances such as floor drains. All conveyances should be evaluated to determine whether they convey unauthorized nori-storm water discharges to the storm drain system. Unauthorized non -storm water discharges (even when commingled with storm water) shall. be eliminated or covered by a separate NPDES Permit. There are many non --storm water discharges conditions, should not contain pollutants industrial activity (i.e., air conditions water line testing, landscaping overflow, Conditions, provides the conditions where storm water discharges are authorized by Monitorina Proaram that, under certain associated with ng condensate, potable etc.). Item D, Special certain listed non - this General Permit. The General Permit requires development and implementation cf a monitoring program. The objectives of the monitoring program are to (1) demonstrate compliance with the General Permit, (2) aid in the implementation of the SWPPP, and (3) measure the effectiveness of the BMPs in reducing or preventing pollutants in storm water discharges and authorized non -storm water discharges. All facility operators (with the exception of inactive mining operations) are required to:
