Pollution prevention practices for PSH operations
Summary of common pollution prevention practices for PSH operations (Source: Scheuler et al., 2004).

| PSH operation | Profile sheeta | Pollution prevention practices |
|---|---|---|
| Vehicle maintenance and repair | H-1 | Drip pans, tarps, dry clean-up methods for spills, cover outdoor storage areas, secondary containment, discharge washwater to sanitary system,proper disposal of used fluids, disconnect storm drains, automatic shutoff nozzles, signs, employee training, spill response plans |
| Vehicle fueling | H-2 | |
| Vehicle washing | H-3 | |
| Vehicle storage | H-4 | |
| Loading and unloading | H-5 | Cover loading areas, secondary containment, storm drain disconnection or treatment, inventory control, dry cleaning methods, employee training |
| Outdoor storage | H-6 | |
| Spill prevention and response | H-7 | Inventory materials, employee training, spill planning, spill clean up materials, dumpster management, disconnect from storm drain or treat. Liquid separation/containment |
| Dumpster management | H-8 | |
| Building repair and remodeling | H-9 | Temporary covers/tarps, contractor training, proper cleanup and disposal procedures, keep wash and rinse-water from storm drain, dry cleaning methods |
| Building maintenance | H-10 | |
| parking lot maintenance | H-11 | |
| Turf management | H-12 | Integrated pest management, reduce non-target irrigation, careful applications, proper disposal of landscaping waste, avoid leaf blowing and hosing to storm drain |
| Landscaping/grounds care | H-13 | |
| Swimming pool discharges | H-14 | Varies, depending on the unique hotspot operation |
| Other unique hotspots | H-15 |
aDue to the volume of material, the reader is referred to Scheuler et al. (2004) to see the profile sheets. Each profile sheet explains how the practice influences water quality and lists the type of PSH operation where it is normally applied. The sheets also identify the primary people at the hotspot operation that need to be trained in pollution prevention. Next, each sheet reviews important feasibility and implementation considerations and summarizes available cost data. Each profile sheet concludes with a directory of the best available internet resources and training materials for the pollution prevention practice. To access this information go to this link and find Urban Subwatershed Restoration Manual Series Manual 8: Pollution Source Control Practices to open the document as a pdf. Hotspot prevention profile sheets are found on pages 109-158. A discussion of stormwater hotspots is found on pages 13-24.
It should be noted that the profile sheets developed by Scheuler et al. (2004) are written primarily from the perspective that the site(s) in question is an existing site and pollution prevention measures are recommended as a retrofit approach. Designers of new sites, however, can still use the guidance effectively.
Wright et al. (2004) provide a detailed description of the rapid field assessment protocol for identifying PSHs and the appropriate pollution prevention practices for the activities causing pollution. The protocol is known as the Unified Subwatershed and Site reconnaissance (USSR) and the PSH assessment is called a Hotspot Site Investigation. These methods are not directly applicable to greenfield development or redevelopment situations; however, they have significant application for NPDES Phase II communities that are working towards compliance with Minimum Control Measures 1, 2, 3, and 6 (public education and outreach, public participation/involvement, illicit discharge detection and elimination, and pollution prevention/good housekeeping, respectively).
