Assessing Environmental Attributes and Legacies of Our Erosion and Sediment Control Materials

Marc S. Theisen, M.Sc., CPESC, CPSWQ, CESSWI – Vice President - Business Development and Technical Services, Profile Products LLC
The Erosion and Sediment Control (E&SC) industry has seen many changes over the past several decades in response to increased regulatory requirements. E&SC has gone from a “nice to have” typically at the completion of a project to an embedded requisite for regulatory compliance. Relevant technologies were initially developed to accomplish two interrelated objectives – erosion control and sediment control, in the context of compliance with landmark legislation including the United States Environmental Protection Agency (US EPA) Clean Water Act, National Pollution Discharge Elimination System (NPDES) and other federal and regional regulatory provisions.

Erosion and Sediment Control Fails, and Alternatives

Paul Mueller, CESSWI – Erosion Control and Stormwater Inspector, St Charles County Government

You’ve paid the engineer to design a stormwater pollution prevention plan, you’ve paid the supply company 1000’s of dollars for erosion and sediment control (ESC) devices, and you've paid for the installation of the ESC devices. So, why now are the regulatory agencies threatening to fine you? With over two decades of experience in inspecting land disturbance sites and providing technical assistance, Mr. Mueller will present photos of drastic best management practice (BMPs) failures and explain why they failed. The discussion will be related back to the U.S. Environmental Protection Agency (EPA) Fact Sheet and EPA’s Construction General Permit requirements in Sections 2.1, 2.3, and 2.4. Photos will demonstrate what to look for during your site inspection to ensure that BMPs were installed correctly.


Basics of BMP Installation
Sonny Johns, MS, CPESC – Senior Stormwater Specialist, Cardinal Strategies

This presentation on the basics of proper Best Management Practices (BMPs) installation will look at some of the industry’s most common BMPs. We will explore both erosion control BMPs and sediment control BMPs. This presentation will reference BMP standards from a non-profit organization in Texas, dedicated to helping our industry. The name of the organization is the North Central Texas Council of Governments or NCTCOG. 


BMP Maintenance for Dummies (That Includes Me)
Paul Chellsen, CPESC, CPSWQ – Supervising Stormwater Technician II, Minneapolis Surface Waters and Sewers

This paper will take you step by step through writing a complete O and M plan that anyone can understand. From the Engineer who designed it to the Condominium Association President that is now left to manage the device.
We will begin by creating a Site and BMP specific plan that clearly details the BMP as it lives. Nearly any BMP can plan can fit on two sides of an 8/12 X 11 Sheet of paper if its done right.


Erosion and Sediment Control on Long Slopes
Bob R. Marshall, CPESC RLA – Erosion & Sediment Control Program Leader - Oregon Dept. of Trans., Oregon Dept of Transport

This presentation offers the story of the US20 safety bypass project through the eyes of the erosion and sediment control designer. US20 is a busy route between Oregon's Willamette Valley and the central coast. The old road, along the Yaquina River was a narrow twisty route constrained by steep canyon walls and the river. This road was the site of frequent and severe accidents. The bypass route was engineered to go over the ridges of the Coast Range. True to its reputation, the location is among the wettest regions in one of the wettest states in the US, with the regional ecosystem considered temperate rain forest. T


Site-Specific Erosion & Sediment Control

Steven Grice, PMP – Director, Precision Dewatering, LLC

Dewatering and stormwater management should not be approached with a one-solution-fits-all plan. Site conditions and seasonality call for a variety of construction plans that support an efficient and environmentally compliant dewatering project. This major project case study will discuss how the variety of challenging terrain in Northern Minnesota meant multiple stormwater and dewatering plans through multiple seasons had to be developed.


My Erosion Control Failed: How Bad Is It? Sediment Characterization and Forensic Wetland Delineation
Daniel DeJoode, PhD – Senior Project Manager, SWCA
Kyla J. Iwinski-Wood, PhD – VP Research and Development, Applied Polymer Systems, Inc.

This paper will present a technique for quantifying and documenting released sediment that is explicit and repeatable. It can be used as a basis for discussion of the severity of the release with regulatory agencies, to plan and prioritize remediation, and to demonstrate remediation success. The techniques presented will include soil characterization from sediment sources and depositions, line intercept sampling, replicated samples, and incorporation of GPS and GIS to document findings. 


Chemical Treatments for Erosion and Turbidity Control: A Review

Richard A. McLaughlin, PhD – Professor and Extension Specialist, Crop and Soil Sciences, North Carolina Stare University

We all strive to reduce erosion and to discharge the best quality water we can from construction sites. There has been a fair amount of research on the use of chemical treatments to enhance erosion control and to help reduce turbidity in construction site runoff. For erosion control, most of the focus has been on polyacrylamide, but there are other chemicals which have been tested, either as a stand-alone product or to augment traditional products such as straw, erosion control blankets, and hydromulch. 

Advanced Stormwater Treatment Considers Deicing Salts’ Impact on Heavy Metals

Jim Merchlewitz, MBA – Water & Wastewater Business Development Manager - US Operations, Shawcor
Co-Presenter:  Carsten Dierkes, Dr Eng 
– Managing Director, H2O Research GmbH

Ongoing research reveals the extent to which heavy metals in runoff is damaging the environment. A little-considered component of the damage is how the addition of deicing salts to roadways and parking lots impacts the mobility of heavy metals. The problem occurs when heavy metals trapped in soil or stormwater treatment systems during the summer are released back into stormwater during the winter. Addressing this issue is of paramount importance, especially for snowbelt states throughout North America.


A Tale of Two Filters: Amending Filtration Media with Biochar to Remove Bacteria from Urban Stormwater

Edward Matthiesen, PE, MCE, MBA – Principal Engineer, Stantec
Co-Presenter:  Justine Dauphinais, MA 
– Water Quality Coordinator, Coon Creek Watershed District

Elevated bacteria levels in the nation’s surface waters is a public health issue that has led to sick pets, beach closures, and may pose an immediate health risks to anyone who recreates in or consumes the water. The culprit is often pet, wildlife, and human waste carried by storm sewers, untreated, to nearby lakes, streams, and rivers. There are numerous Best Management Practices designed to remove conventional pollutants from stormwater, but very few that target bacteria. Biochar, a charcoal-like substance made via pyrolysis of organic material, has recently been gaining attention as a potential filter media amendment for removing bacteria. 


Biofiltration Media: What to Choose and Why
Andy Erickson, PhD, PE – Research Associate, St. Anthony Falls Laboratory, University of MN

Biofiltration is a common stormwater treatment practice throughout the state of Minnesota, particularly in urban areas. However, professionals continue to face design challenges pertaining to media mixes, particularly those containing compost which have been shown to export phosphate which can cause algal blooms in lakes. This study consists of 30 outdoor biofiltration mesocosms comprising nine different media mixes compared to clean washed sand (three replicates of each mixture). 


Cameron Peak Post Fire Restoration

 Chuck Herrmann, CPSS – Principal Environmental Scientist, Stantec Consulting Services, Inc., Denver Raemisch – Marketing Manager, Silt Sock Inc., Beau Lane – Sales Manager, Silt Sock Inc.

This will be a case study showing post fire restoration efforts after the Cameron Peak Fire that occurred in Colorado at the end of 2020. Erosion and sediment control practices and products will be discussed with supporting photos, videos, and data. The Cameron Peak Fire of 2020 was the largest wildfire in Colorado history. The watersheds affected have concerns over water quality as they provide drinking water to a large urban area (Fort Collins, Greeley, Loveland, etc).

After stints as commercial fisherman and ski area bartender I buckled down and became a landscape architect. I worked for 25 years as a consultant for David Evans and Associates, a mid size multi disciplinary consulting firm as a Project Landscape Architect on a wide range of projects. I worked on schools, hospitals, cemeteries, parks and residences but my primary focus was streetscapes and roadsides where I designed the landscapes and erosion and sediment control.. These were not glamorous projects but big and important work that was viewed in passing by millions of travelers. In 2016 I became the Project Landscape Architect for a huge and failed project that cut through the temperate rain forest of the Oregon Coast Range. After providing a design that stabilized roadside soils in the Coast Range I was offered a position with Oregon Department of Transportation where I now sit as the Roadside Development Program leader and also the Erosion and Sediment Control Program Leader. Again, this work is not glamorous, but big and important and affords me the opportunity to work with a great team in a beautiful state.
