NR 216.27(3)(d)(d) The SWPPP shall summarize any results of available storm water sampling data or other observations that characterize the quality of storm water discharges or identifying sources of storm water contamination. Available data that characterizes the quality of storm drainage discharges under dry weather flow conditions shall also be included, except when the data has been or will be reported to the department under another WPDES permit.
NR 216.27(3)(e)(e) The SWPPP shall identify all potential source areas of storm water contamination including:
NR 216.27(3)(e)1.1. Outdoor manufacturing areas.
NR 216.27(3)(e)2.2. Rooftops contaminated by industrial activity.
NR 216.27(3)(e)3.3. Industrial plant yards.
NR 216.27(3)(e)4.4. Storage and maintenance areas for material handling equipment.
NR 216.27(3)(e)5.5. Immediate access roads and rail lines.
NR 216.27(3)(e)6.6. Material handling sites including storage, loading, unloading, transportation, or conveyance of any raw material, finished product, intermediate product and by-product or waste areas.
NR 216.27(3)(e)7.7. Storage areas for raw materials, finished and intermediate products including tank farms.
NR 216.27(3)(e)8.8. Disposal or application of wastewater.
NR 216.27(3)(e)9.9. Areas containing residual pollutants from past industrial activity.
NR 216.27(3)(e)10.10. Areas of significant soil erosion.
NR 216.27(3)(e)11.11. Refuse sites.
NR 216.27(3)(e)12.12. Vehicle maintenance and cleaning areas.
NR 216.27(3)(e)13.13. Washing areas for equipment, vehicles, containers or other material.
NR 216.27(3)(e)14.14. Shipping and receiving areas.
NR 216.27(3)(e)15.15. Manufacturing buildings.
NR 216.27(3)(e)16.16. Residual treatment, storage and disposal sites.
NR 216.27(3)(e)17.17. Any other areas capable of contaminating storm water runoff.
NR 216.27(3)(f)(f) Specific pollutants likely to be present in storm water as a result of contact with source areas identified in par. (e) shall also be listed.
NR 216.27(3)(g)(g) The SWPPP shall identify all contaminated and uncontaminated sources of non-storm water discharges to the storm sewer system and indicate which are covered by WPDES permits. The SWPPP shall contain the results of the non-storm water discharge monitoring required by s. NR 216.28. If monitoring is not feasible due to the lack of suitable access to an appropriate monitoring location, the SWPPP shall include a statement that the monitoring could not be conducted and an explanation of the reasons why.
NR 216.27(3)(h)(h) The SWPPP shall rely to the maximum extent practicable, and to the extent it is cost effective, on the use of source area control best management practices that are designed to prevent storm water from becoming contaminated at the site. Source area control best management practices that are either proposed or in place at the facility shall be indicated on the facility drainage base map. The SWPPP shall provide for the use of the following applicable source area control best management practices:
NR 216.27(3)(h)1.1. Practices to control significant soil erosion.
NR 216.27(3)(h)2.2. Good housekeeping measures, preventive maintenance measures, visual inspections, spill prevention and response measures and employee training and awareness.
NR 216.27(3)(h)3.3. Covering or enclosing salt storage piles so that neither precipitation nor storm water runoff can come into contact with the stored salt; or, for facilities that use brine and have salt storage piles on impervious curbed surfaces, a means of diverting contaminated storm water to a brine treatment system for process use.
NR 216.27(3)(h)4.4. Use of a combination of precipitation control, containment, drainage controls or diversions to control section 313 water priority chemicals potentially discharged through the action of storm water runoff, leaching or wind.
NR 216.27(3)(i)(i) The SWPPP shall maintain best management practices necessary to maintain compliance with the performance standards in s. NR 151.12 for those areas that are described in s. NR 151.12 (2).
NR 216.27(3)(j)(j) The SWPPP shall identify pollutants that are likely to contaminate storm water discharges to waters of the state following implementation of source area control best management practices. Past sampling data collected at the facility or at sufficiently similar outfalls at other facilities may be used in making this determination. At a minimum, all of the following pollutants shall be considered for their potential to contaminate storm water:
NR 216.27(3)(j)1.1. Any pollutant for which an effluent limitation is contained in any WPDES permit issued to the facility by the department.
