 TECHTALK
by Dr. Jim Spotts
TechTalk is a forum for resolving erosion and sediment control and/or construction related problems from a technical perspective. Technical questions are submitted by the reader; suggestions may be from Southeast Environmental Consultants, LLC, (SEC) or other sources. The reader is solely responsible for the results, if the suggestion is implemented.
 Question The recent rain events are causing truck tires and delivery trailer tires to pull large amounts of bare soil from the corners adjacent to my stone exit and onto the paved roadway, which has resulted in several Stop Work Orders. What can I do to keep the trucks onto the exit when they turn?
This is a common problem. Rather than installing barriers in an effort to change the driving behavior of every truck driver leaving your site, you should widen the corners of the pad with nonwoven geotextile and 1.5" to 3.5' stone. |
Remember when Grandpa would spray his used oil on the dirt road in front of his house to keep the dust down. Or better yet, have you been driving on I-85 or I-75 and observed a GDOT roadway project spewing out a HUGE DUST Cloud so thick that your afraid your truck will get totaled when you drive into it....so you quickly roll up your windows and turn your A/C on recirculate to keep your interior from turning into sand box.
Well.....polyacrylamide once again comes to the rescue. Polymers (the lab tested, soil specific, anionic type) are a cost effective and environmentally friendly way to keep everyone happy (GDOT included).
BEFORE AFTER
Silt Stop (a registered trademark) material is designed to agglomerate dust and retain the agglomerate for 1-4 days, while still allowing water to penetrate the soil. This has shown to reduce airborne dust from open areas on construction sites, haul roads, waste dumps, and tailings piles, and will save time, labor and water.

New Bill To Restore Protections for Wetlands
Millions of Acres Threatened
 Washington D.C. (April 2, 2009) America's wetlands would have their Clean Water Act protections restored under a new bill introduced today by U.S. Senator Russ Feingold (Wisc.) and 23 co-sponsors. The Clean Water Restoration Act, which is supported by Ducks Unlimited and other conservation/sportsmen's groups, would restore protection to more than 20 million acres of geographically isolated wetlands at risk of pollution and destruction under current guidance from the Environmental Protection Agency and Army Corps of Engineers.
