Denver Dirt Pile

Just a nice dirt pile in Denver. Walking around between presentations at the International Erosion Control Conference in February 2019 and saw this. A little utility work in the street, going to reuse the excavated dirt, placed it on plastic, put some berms around base, no rain in the forecast and the dire goes back in the hole later in the day so no need for cover.

Prevent Sediment Trackout

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.
