Work proceeds at Penny Park with the installation of crumb rubber pads under some of the play equipment. The rubber pad above is about 3/4 complete; wood chips and dirt have been scraped away for the pad and some dirt will have to be removed to smooth the areas between pads. When the rubber crumbs are dry the pads will be a light gray as seen in the bottom photo. But the pads are not rolled out, they are poured much like a very dry concrete.

Image
The ground up rubber from old tires comes in large paper sack like ready mix but bigger. The bags are emptied into a box shaped cement mixer and glue is added then mixed for a very long time, wheelbarrow to the location and spread and smoothed.

The projects cost is $27,233.98 and is being funded by a $25,397 "Recycle and Illegal Dumping Grant" from the NM Environment Department and $1,836.98 from the Town of Silver City.

There's no doubt this material is an example of a recycling success story, and it prevents thousands of broken bones that would otherwise result from falls on playgrounds and athletic fields. It's far better than wood mulch in that regard and way better than pea gravel or dirt making it a wonderful ground treatment for Penny Park. However, among other things, it's available in a whole rainbow of colors. Okay, so light gray is nice, but we could have done something like this,

and I'll bet our local artist community would have had a blast creating a design for it.

Saturday the workers ere back to place the color /sealer coat on the base, a solid forest green. Expecting to finish Saturday they will be back to top coat a few other pads and fix the landscape.

For those interested in the product, MSD's (Material Safety Data), installers dangers (interesting), toxic fumes from Di-phenylmethane Di-isocyanate that are claimed to dissipate making the play area safe and more. Click Here To Find The Documents.

forgot to mention, when we arrived at the park Saturday afternoon the smell was remarkably noxious.

Isn't that the same aroma that diminishes into what's commonly called, "new car smell"? Most polymer based products smell pretty strong when they're first being formed. We're actually painting the inside of our house right now with latex paint, talk about a benign material, but man what an aroma it off gases while it's curing. That's just the nature of the beast. And in any case, while the smell at the park won't last long the final product will protect fragile little bones for a very long time. And that seems like a really good trade off to me.

Glad to hear they're at least laying down a green surface coat. I still think they could have been a bit more creative but the green looks nice. Better than gray.

What's really heartening about this is knowing that when the City found out they had an opportunity to further improve the park they took advantage of it. In that regard they're doing exactly what we hoped they'd do when we elected them. And when you put this all in context it really seems to me the Town deserves kudos. Consider the fire(s) that turned the park into ashes, followed by the CCA eradication debacle, plus the various skate park debacles, and that the entire facility was basically dumped on the City without warning, and that the City had zero budget, planning, or resources to attend to any of this, and from that entire mess created what's there today, and continues to improve upon it. Can you imagine our Federal Government being run as well!

Thanks for the update on this Crow.

Thanks Kevin, it was not the polymer that we were smelling but rather the Top Coat which contains something called N-Methyl-2-Pyrrolidone a toxic chemocal as outlined in its MSDS attached below and partly quoted next. Note the parts in bold for this Toxic Chemical.

"TSCA: All components in this mixture are included in the TSCA Inventory.
US EPA Emergency Planning and Community right to Know Act (EPCRA) SARA Title III:
Section 302 Extremely Hazardous substances (40CFR 355), Appendix A: None
Section 313 Toxic chemicals (40 CFR 372.65): CAS # 872-50-4 N-Methyl-2-Pyrrolidone 3.45% by weight."

By their own admittance the company says the jury is still out on any long term problems with these products or ingredients.

Latex is not a benign material, millions are highly allergic to both the fresh paint and latex cloves hence the development of latex free cloves especially for the medical/dental profession.

If you've never walked on these Crumb Rubber Pads you should visit the park if for no other reason than to try it out, it's sort of akin to walking on a mattress. But if you suffer asthma or are especially sensitive to toxic fumes wait a couple of more days. The park was opened this morning and I stopped by about 10:30 am and in spite of the wind the smell was powerful, by 4:30 pm the smell was less but still there. I would suppose by tomorrow afternoon only the most sensitive people should detect an odor.
