1. 1 Baseline Practices for Storm Water Protection ©2002 Dr. Bradley C Paul

2. 2 Step #4 Best Management Pract.  Identify areas where storm water may contact contaminant materials  Select Best Management Practices for those areas

3. 3 Types of Best Management Pr.  Baseline Practices –Involve operations and handling practices usually cheaper  Structural Practices –Involve building something to control –Problems with Building Structures in Wetlands Impoundment may be considered discharge to groundwater Erosion control may overlap soil conservation Construction permits may get into Zoning Issues

4. 4 Baseline Management Pract.  Good Housekeeping –Round up Crud before it contacts storm water –Keep Floors and Ground Surfaces Clean –Sweeping Shoveling and Vacuuming are major accepted removal practices Don’t hose it down - you just contaminated water Don’t wait till after it has rained - use a schedule –Front end loaders and bobcats may clean up larger spills - hand shoveling can be labor intensive –Vacuum equipment may produce recycle

5. 5 Operations and Maintenance  Have regular trash pick-up and debris removal  Use Rapid Recycling Collection  Inspections for leaks in chemicals and fuel storage or even rock bins –Try to search and fix during regular maintenance –Lots of people try short-cuts here  Store in Proper Durable Containers  Train Crews in Spill Clean-up Methods

6. 6 Materials Storage Practices  Provide Adequate Isle and Maneuver Space for Handling (so they don’t bash in all the drums trying to handle them)  Maintain an Inventory of What You Have –Often can save money on inventory –Walk Through and See What you have –Check Last Years Invoices –Keep up Labels - people toss mystery stuff –Keep MS Data Sheets file for everything

7. 7 Chemical, Lube, Fuel Drums  Keep in contained or curbed areas so leaks can’t go anywhere  Keep out of direct traffic routes to reduce accidents from people unable to drive  Store off of ground to avoid corrosion around base  Have a lot of people trained in clean up - but only a few responsible for inventory

8. 8 General Source Materials  Store Indoors - works for chemicals but probably not aggregate piles  Cover the pile and put diversion berm around to route storm water away from the evil contaminant  Look for Guidelines that may exempt your coarser rock from being an evil contaminant –You may not be able to cover everything but maybe you only need to guard your finer material

9. 9 Other Cover Applications  Often feasible to have covered refueling depots - your employees may actually think you were setting up a convenience for them  Look at use of tarps for things temporarily outside

10. 10 Include Employee Participation  Have Regular Training and Review  Put up Bulletin Boards and Posters  Include Treatment in Meeting Agendas

11. 11 Dust Control  Settled Dust may get you out of Clean Air Regs but it can get you nailed in Storm Water  Avoid Denuded Areas - vegitation makes you look more environmental friendly anyway  Use Wind Breaks Like Trees  Have coarser material at surface so water can’t run off with fines

12. 12 More Dust Control  Do look at wetting down but not enough to produce run-off  Do consider surfactants –don’t use oils because they are evil contaminants of soils –use in drier areas where water cannot carry off –keep away from traffic so tires can’t spread  Look at Dry Collection –especially if a recycle opportunity exists

13. 13 Use Preventative Maintenance  Regularly Inspect and Maintain Storm Water Handling Facilities –Keep onsite records of own - not necessarily sent in –Be careful with sensitive information - public access not well defined  Regular Maintenance of Things that could release contaminants –Hydraulics on Equipment

14. 14 More Preventive Maintenance  Have a list of everything that needs inspection  Have a schedule for those inspections  Have records of Results of Inspections  Have records of Timely Corrective Actions taken as result of those inspections  Maintenance may save you down time on production –Accident could trigger prosecution from unexpected statutes

15. 15 EPA Itemizes for Inspection  Pipes  Pumps  Storage Tanks and Bins  Pressure Vessels  Pressure Related Valves  Pressure Release Valves  Process and Materials Handling Equipment  Storm Water Management

16. 16 Have Facilities Inspections  Look for things that could cause discharge of priority chemicals  Things that could cause contact with finished or unfinished goods (rock in a quarry)  Bins and related dust patterns  Lot of things can be added to inspections to avoid equipment failures

17. 17 Lots of Inspections  Most inspections can be visual  Need to have “qualified personnel” do inspections –Should be a responsible person who keeps a record of finding and response actions –Need to be familiar with SWPPP –Some have suggested surveillance and security people  Occasionally need chemical and acoustic weld tests
