Managing Construction Projects to Prevent Sediment Trackout

I originally submitted this abstract for the 2019 IECA Denver conference . It was not accepted as a presentation but as an article in the October 2018 edition “Environmental Connection Magazine”.

Abstract
Sediment tracking from construction sites onto public roads and highways is a continual source or frustration for both regulators and contractors. The standard best management practices (BMPs) available, such as stabilized construction entrances and sweepers, often don’t work at all and, at best, only reduce total sediment by 30-50% which is inadequate for preventing water quality violations. In addition to water quality problems, sediment tracking onto roadways can generate dust, which may violate clean air standards and cause unsafe conditions, especially on highways.
This paper will discuss BMPs, methods, and procedures, which can be used by contractors to prevent sediment from being tracked onto roadways in the first place. In addition, ways to significantly reduce sediment loss will be presented. Some of these methods include:

• Passive tire baths
• Various tire washes
• Keeping vehicles of dirt
• Vacuum vs. mechanical sweepers
• Road washing
• Contract specifications

Each method will be discussed with pros and cons, design information and contract specifications.

Polymer Use and Testing for Erosion and Sediment Control on Construction Sites
By Scott Tobiason, David Jenkins, Ed Molash, Stacey Rush

Tested in the soggy La Niña weather conditions of the Pacific Northwest, chemical polymers promise a cost-effective, safe way to prevent soil erosion and remove suspended sediments from construction-site runoff.
