Turbidity Reduction Techniques for Pumping Operations on Construction Sites




Have you ever sampled and measured turbidity numeric levels for pumping or dewatering operations on your construction site? How turbid is your discharge from your work zone while working on a borrow site or pipe culvert near a stream? Will your discharge meet effluent limits prior to entering jurisdictional waters? This webinar will cover a number of techniques to reduce turbidity levels from pumped effluent. Learn about new technologies, design strategies, and case studies to maintain water quality near your construction operation.

EPA to Reconsider Key Aspect of Construction Stormwater Rule

Nearly a year after finalizing its construction stormwater rule, in response to objections from industry groups, EPA has conceded that the controversial numeric turbidity limit in the rule is flawed. EPA issued the final construction stormwater effluent guidelines rule[1] (the “Rule”) in December 2009, for the first time establishing a numeric limit on the turbidity of stormwater discharges from large construction sites and requiring monitoring to ensure compliance with the numeric limit. The Rule also required nearly all construction sites that obtain stormwater permits after February 1, 2010 to implement a range of erosion and sediment controls and pollution prevention measures. EPA’s Rule elicited immediate criticism, including a lawsuit brought by industry groups in the Seventh Circuit,[2] and a petition for administrative review by the Small Business Administration (“SBA”) Office of Advocacy. A primary element of these challenges was the claim that EPA’s numeric turbidity limit is flawed. (more…)

Original WSDOT Erosion Control Web Pages

Filed under: Web Site — Sheetflow @ 12:52 am

The Washington State Department of Transportation (WSDOT) began their Construction Erosion and Sediment Control program in 1996 when they hired their first State-wide Erosion Control Coordinator, whose responsibility was develop and implement a contractor certification program, write and publish contract specifications, and provide state-wide, consistent, technical expertise. These are the early web pages developed for the program:

Controlling Fugitive Dust at Construction Sites-Air Quality in Idaho


What is Fugitive Dust?

It’s Air Pollution. Dust is particulate matter (PM) consisting of very small particles. Fugitive dust is PM suspended in the air primarily from soil that has been disturbed by wind or human activities, such as earthmoving and vehicular/equipment traffic on unpaved surfaces.

EPA Watershed Academy

Welcome to the Watershed Academy’s Distance Learning Program — Watershed Academy Web. This Web site offers a variety of self-paced training modules that represent a basic and broad introduction to the watershed management field. The modules are organized by the six themes listed below. Modules vary in the time they to complete, from ½ hour to 2 hours. Fifteen of them (marked with asterisks * below) are the core modules for the Watershed Academy Certificate Program.

Guide to Meteograms, Part 2

Meteograms: Messages in Time

As an apprentice forecaster, you will learn that sometimes it’s advantageous not to display weather data “spatially” (on a map), but, instead, to display weather data with respect to time. In these instances, weather forecasters focus their attention on a specific weather station or airport and watch how atmospheric variables on the station model unfold in time (usually over a 24-hour period). Such a “time display” is called a meteogram (a sample meteogram appears below, courtesy of Unisys Corporation). It represents the evolution of a series of weather observations taken at the Pittsburgh International Airport. More…

Prominent Pierce County Developer Sentenced To Prison For Criminal Violations Of Clean Water Act

Prominent Pierce County Developer Sentenced To Prison For Criminal Violations Of Clean Water Act

One of First Prosecutions in the Nation for Stormwater Violations

FOR IMMEDIATE RELEASE

October 10, 2012

A prominent Sumner, Washington developer was sentenced to prison today in U.S. District Court in Tacoma for a felony violation of the Clean Water Act. BRYAN STOWE, 65, was sentenced to six months in prison, one year of supervised release, and a $300,000 fine for knowingly violating a national pollution discharge elimination permit. In addition, STOWE will make a $100,000 payment to the National Fish and Wildlife Foundation for environmental projects targeting resources impacted by the illegal discharges. STOWE, as president and co-owner of Stowe Construction, Inc., admitted knowingly violating the Construction General Storm Water Permit for the Rainier Park of Industry project, located on West Valley Highway in Sumner. Permit violations contributed to two major landslides at the site in 2010 and 2011. Both slides forced closure of the West Valley Highway. This case is one of the first storm water pollution criminal cases brought in the United States. At sentencing U.S. District Judge Ronald B. Leighton referenced the Clean Water Act saying, “These regulations serve a broad and useful purpose. You violated them persistently. You were wrong.” MORE…
