Script for Module 2: What is a SWPPP



Script for Module 4: Materials Management

Slide 1: Welcome back to our training session.

Slide 2: We’ve looked at the concept of watershed and concern over runoff. We’re familiar with our SWPPP, and we’ve addressed spill prevention and response. Today our focus is on materials management.

Slide 3: Our review today will cover three broad areas: purchasing, storage and usage of materials.

Slide 4: Let’s start with some basic suggestions on purchasing to minimize stormwater pollution.

Slide 5: Order what you need in appropriate amounts. This can avoid having to throw out anything that has an expiration date. You can also avoid having to figure out what to do with all the material that won’t fit into your storage area.

Now maybe this isn’t what it looks like, but the whole purpose of building all of those salt sheds is to get the supply under cover…

Slide 6: Inspect any containers you receive immediately upon delivery. Make sure that they are not damaged or leaking

Slide 7: And, if feasible, look for alternative products that can do the job with less potential for damaging the work environment and the surrounding area.

Slide 8: So, you’ve carefully selected the materials you need, and ordered in quantities that you can handle. Now what do you do with it?

Slide 9: DPW facilities need 2 broad categories of materials. The first, that I’ll call “little stuff”, is the typical materials any facility that has vehicles and machinery would have. Then, there’s the “big stuff”; the bulk materials we need to maintain roads and the waste materials we collect from that maintenance.

Slide 10: There are lots of tips and training materials out there on storing the little stuff, because some of it is hazardous material. The most basic tip is to keep it indoors and out of contact with stormwater, which is the main concern of these modules. So, we’ll only briefly touch on indoor materials storage. Which is not to imply we’re all doing a great job of getting things under cover!

Slide 11: Identify areas where spilled products could enter the outdoor environment: such as drains, doorways and loading docks. Keep materials out of those points as much as possible.

Slide 12: Keep an inventory of the materials on hand, and know where they are. If a product comes in a container, keep it there until it’s used.

Slide 13: When storing wastes from the “little stuff”, make sure the containers are clearly labeled as to what’s in there, when contents were first added and what the hazard is, if any. Used batteries are among the wastes that can be recycled – they should be stored in a single layer, on pallets that have a non-corrosive base

Slide 14: If you must store bagged or boxed products outdoors, get them up on a pallet and make sure they’re covered. Routinely check for leaks.

Slide 15: And make sure the dumpsters have lids, and that they’re out of any identified flow paths

Slide 16: Now for the big stuff. We touched on many of these points in the module on spill prevention; if some of these slides will look very familiar, its because you saw them in the last module.

Slide 17: For instance, this picture, where it was suggested that we don’t put our salt/sand pile right next to the flow path.

Slide 18: One of the requirements of the MS4 General Permit (remember that from the SWPPP module?) is that salt and salt/sand piles MUST be enclosed or covered by a storm-resistant shelter. Thanks to some grants and reallocations of money, Rhode Island is starting to get a handle on enclosing the salt piles. (Watch those spillage points!)

Slide 19: Eventually, it would be best to get all the bulk materials under some sort of cover.

Slide 20: At the very least, we should contain materials with berms or dikes, or create a sump so runoff from the pile slows down and drops its load. This illustration from the Salt Institute’s Salt Storage Handbook shows both containment dikes and collecting basins or sumps. Plus, the piles are covered.

Slide 21: Does anyone want to suggest the differences between this picture and the Salt Institute’s illustration?

(Elicit answers from group: no cover, inadequate dike, no sump)

Slide 22: This might be a good time to talk about sweepings, one of the bulk materials that seem to be a poser at a number of sites in RI.

Slide 23: You spend most of the winter mixing sand and salt and applying it to the roads and then you have to go back and sweep up what’s left, along with whatever else folks dropped onto the road. Then you haul it back to the facility, and then what? Well, according to the Rules & Regs for Composting Facilities and Solid Waste Management, perhaps along with Freshwater Wetlands Regs, you shouldn’t be doing this.

Slide 24: According to the Solid Waste regs, we can use sweepings for landfill cover, as a base course, or as backfill in drainage projects, without having to get it tested.

Slide 25: But if we want to use it as clean fill, we have to first submit a sampling plan to RIDEM’s Office of Waste Management, then conduct the testing, and submit results to Waste Management for approval before it can be used for fill.

Slide 26: So, in the ideal world, each facility might have two storage areas for sweepings – one for the amount we estimate we’ll need during the year for backfill, etc. and the other that’s only there until the next truck goes to Central Landfill.

Slide 27: Now let’s take a brief look at using materials in a manner that minimizes exposure to stormwater runoff. Once again, if this process sounds a lot like spill prevention to you, it’s because it is very similar.

Slide 28: Most of these tips focus on the small stuff, like keeping containers closed except briefly while in use. And that includes the dumpster.

Slide 29: Make sure any fluids you use have self-closing spigots and nozzles. And place drip pans beneath any hose or pipe connections.

Slide 30: Pour and mix products in a well-ventilated area over a spill pallet

Slide 31: Pallets won’t work so well with the bulk materials, now will they? So designate an area away from runoff paths, and keep it clean.

Slide 32: Use as few spray cans at a time as feasible for carburetor cleaners, lubricants, etc. Check the cans for proper disposal.

Slide 33: Make it a habit to get the empties to their proper final destination before breaking out new materials. Drums & containers should be sealed and labeled.

Slide 34: And always make sure spill cleanup materials are nearby before you start an activity.

Slide 35: Clean up when you’re done, using dry cleanup methods.

Slide 36: And that wraps up the materials management training module.

Note: Power Point continues with slides for the exercise.
