Flocculants are powerful tools that have been used for decades to control erosion, stabilize soil, and remove harmful contaminants from water. Flocculant treatments can meet very low discharge limits, allowing sites to stay in compliance, meet regulations and improve stormwater quality and clarity. Applied Polymer Systems introduced flocculants to the erosion and stormwater industries in the 1990s, drawing from decades of research and use in mining effluent treatment. Anionic polyacrylamide is the most widely accepted and commonly used flocculant due to being both safe for aquatic life, and highly effective.

flocculant (Floc) Logs and Polymer Enhanced BMPs to the industryFREE EVENT
Part One Presenter: Seva Iwinski, Vice President - Applied Polymer Systems
Part Two Presenters: Kyla Wood, Head of Research and Development & Eddie Snell, Technical Specialist - Applied Polymer Systems
Flocculants are powerful tools that have been used for decades to control erosion, stabilize soil, and remove harmful contaminants from water. Flocculant treatments can meet very low discharge limits, allowing sites to stay in compliance, meet regulations and improve stormwater quality and clarity. Applied Polymer Systems introduced flocculants to the erosion and stormwater industries in the 1990s, drawing from decades of research and use in mining effluent treatment. Anionic polyacrylamide is the most widely accepted and commonly used flocculant due to being both safe for aquatic life, and highly effective.
PAM use is rapidly expanding across the US and world thanks to its safety for environmental applications and effectiveness at targeting and removing difficult and common pollutants like clay, sediments, and metals. In our Let’s Talk Floc Part 1 webinar we detailed the movement and growth of PAM use for erosion and sediment control from its introduction in the 1990s to its widespread and growing adoption in the US today. We also spoke about the important factors that influence how we use flocculants safely and effectively. In Let’s Talk Floc Part 2, we will build on this important information and focus on case studies and examples of how PAMs were, and currently are being utilized to successfully manage erosion, sediment, metals, and stormwater on multiple projects across the United States and Canada. Join Applied Polymer Systems, the company who brought flocculant technologies to this industry 25 years ago, in the second part of our two series Let’s Talk Floc webinar, as we cover how to effectively, safely, and efficiently use flocculants in the field to meet stormwater and erosion and sediment control goals and requirements.
Thanks to years of education and concerted effort by universities, companies, and organizations like the IECA, flocculant use has evolved from sparse use of what many deemed mysterious “fairy dust”, to widespread adoption and a push towards standardized flocculant training, use and application. With many states recently adopting, preparing to adopt, or considering adopting anionic polyacrylamide into their toolboxes (i.e. pre-approved flocculant lists, QPLs/APLS, or erosion control and stormwater manuals) interest in flocculants and demand for training and information has reached levels never seen before in our industry. Despite expanded use and interest, confusion and questions still exist, and education is needed to ensure flocculants are used safely and effectively. Join Applied Polymer Systems, the company who brought flocculant technologies to this industry 25 years ago, as we cover how to effectively, safely, and efficiently use flocculants to enhance traditional best management practices to meet stormwater and erosion and sediment control goals and requirements.
Part One Learning Objectives:
- Understanding the basics of flocculant technologies and how to select safe and effective flocculants for treatment systems
- Understand what anionic polyacrylamide is, how it works, and why it is the standard flocculant used for erosion and sediment control and stormwater treatment in the industry
- Gain a basic knowledge and understanding of the steps needed to apply, maintain, and troubleshoot flocculants in field applications
- Recognize how traditional BMPs may be enhanced using anionic PAM to improve sediment control and water treatment
Part Two Learning Objectives:
- Review how to select appropriate flocculants for projects based on specific project goals and site characteristics.
- Learn components needed to plan and implement effective PAM treatments for Erosion and Sediment Control and Stormwater Management.
- Understand common management and use requirements for PAM applications through real world examples and case studies of PAM treatments.

Balancing Roadways with Vegetated Systems: Seeking Resilient Stormwater Management in a Linear Environment to Meet MS4 Requirements
Brenda Macke, PE, PMP, CFM Project Manager Burns & McDonnell Kansas City, Missouri, United States
Co-presenter: Kylie Clark, MUP, AICP, ENV SP Urban Planner Burns & McDonnell, United States
Co-presenter: Dale Kirmer, Professional Engineer (he/him/his) Engineer Kansas Department of Transportation Topeka, Kansas, United States
The Kansas Department of Transportation (KDOT) was issued six new MS4 permits in 2020, applicable to the state-maintained roadway in six urbanized areas. The new format of the MS4 permit issued by the Kansas Department of Health and Environment (KDHE) requires permittees to accumulate a required number of points in each permit year, based on a defined menu of Best Management Practices (BMPs) listed for each of the minimum control measures. This predefined menu of BMPs is centered around municipal stormwater implementation, presenting challenges for application in the linear highway environment. This paper and presentation will explore how KDOT is addressing these challenges, with a focus on post-construction stormwater management implementation and how KDOT is addressing other BMPs that are more municipal focused.Chemical Treatment of Sediment Retention Ponds in an Ever-Changing Climate Landscape
Chris Wilcox, PhD, BSc(hons), CPESC (he/him/his) Senior Environmental Advisor HEB Construction, Auckland, New ZealandNew Zealand, and in particular Auckland City, has soils with high concentrations of clays lurking just beneath the topsoil. Being relatively close to the surface, any earthworks activity results in the exposure of these soils to the erosive effects of nature, in particular rainfall. Out of the three soil constituents’, clays are the hardest to erode, however once eroded clays are the most difficult to remove from water owing to their small particle size and surface charge. Auckland, and now the majority of New Zealand, have attempted to tackle the problem of sediment generation from construction sites and the resulting sedimentation of waterways and the environment by trapping sediment on site. The industry and regulators have lent heavily into sediment control by designing robust sediment retention ponds (SRP) and enhancing their treatment efficiency with chemical coagulants and flocculants.
Considerations When Permitting Construction Projects at Existing Facilities
Kenneth A. Gouvion, MS Biology, CISEC, CPESC Senior Environmental Scientist Burns and McDonnell Engineering, Inc. Olathe, Kansas, United StatesConstruction projects that are on existing and operating facilities can pose additional concerns not associated with greenfield construction. These facilities may have existing permits, with specific sampling parameters outlined, that your project will have to consider. There may be the potential for contamination on-site, and special waste handling procedures that will have to be addressed. It may even affect how you permit the project. These items may come into play when developing your Stormwater Pollution Prevention Plan (SWPPP) and how waste material is handled.
Improving the Design and Performance of Double Row Sediment Barriers
Jarrell B. Whitman, PhD, PE, CPESC Assistant Professor Middle Tennessee State University Murfreesboro, Tennessee, United StatesSediment barriers (SBs) are stormwater management devices often installed along the perimeter of a construction site to intercept and treat overland sediment-laden flow prior to discharge into the surrounding environment. Effective SB practices remove stormwater pollutants by creating a temporary impoundment upstream of the practice which facilitates sediment capture via sedimentation. Controlling agencies and design practitioners often specify the installation of two SB practices (i.e., primary and secondary SB) in areas where enhanced stormwater treatment is critical due to downstream environmental concerns (e.g., impaired waters). This study sought to identify the overall performance of a commonly specified double row SB (i.e., double row silt fence), as well as six alternative designs that utilized various secondary SB practices that could be easily paired with a primary silt fence SB.
Largely Unchanged 1990s Sediment Treatment Design in the Context of a Changing Climate and an Ever-changing Landscape of Construction Related Compliance Conditions
Simon N. Cathcart, MSc(Hons) CEnvP CPESC National Environmental Manager HEB Construction Ltd Hamilton, Waikato, New ZealandNew Zealand arguably leads the world in the design, building and operation of the high efficiency sediment retention ponds. While the rest of the globe works to catch up with this highly effective technology the New Zealand leaders in the deployment of this approach have their eyes on the future, a future where changes in climate and compliance standards represent challenges to the success of these 30-year-old design specifications.
Intended to provoke, this opinion piece takes a reflective look at the implications for contractors in 2022 and beyond who have grown up with Auckland Council’s Technical Publication 90 (TP90) and more recently Guidance Document 5 (GD05). As design specification bibles these may now be starting to show inconsistent outcomes in certain circumstances.
Let's Settle It: What Does It Take for an In-channel Sediment Basin to Be Effective?
Jaime C. Schussler, PhD, CPESC IT, EIT Assistant Professor Oklahoma State University Stillwater, Oklahoma, United States
Sediment basins can effectively capture sediment if properly designed and implemented; however, design and installation techniques are greatly variable. In-channel sediment basins were identified as common practices on Iowa DOT construction sites and have been evaluated using field monitoring and large-scale testing techniques since 2018. In the spring of 2022, performance evaluations were completed at the Auburn University Stormwater Research Facility. The current Iowa DOT temporary sediment control basin standard specifies constructing an earthen dam across a conveyance channel to create an impoundment favorable for sedimentation, which is dewatered through a perforated riser pipe and auxiliary spillway. Researchers evaluated sediment basin performance based on the sediment retention volume and turbidity reduction provided by structural and chemical treatments.
Monitoring Construction Site Runoff for BMP Performance
Richard A. McLaughlin, Professor and Extension Specialist North Carolina State University Raleigh, North Carolina, United StatesTesting erosion and sediment control practices is an important part of making recommendations for their use or even their discontinuation. The best way to conduct these tests is under controlled laboratory or field conditions in which the variables are largely controlled. However, it can also be important to see how these practices perform under actual construction site conditions, which may include a wide variety of storm events, non-ideal conditions, and influences of construction site management. This presentation will review how the McLaughlin team has approached construction site BMP testing, the results, and what we learned along the way.
Monitoring Water Quality in and out of Sediment Basins During Highway Construction
Christina Kranz, PhD (she/her/hers) Postdoctoral Research Assistant North Carolina State University Raleigh, North Carolina, United States
Co-presenter: Richard A. McLaughlin, Professor and Extension Specialist North Carolina State University Raleigh, North Carolina, United StatesSediment discharge from construction sites can have harmful effects on aquatic life. Sediment basins are often used to capture runoff with high loads of sediment to settle out the suspended sediments (SS) prior to discharging into adjoining waters. Polyacrylamide (PAM) is widely used as an effective flocculent to improve SS capture. PAM can be placed in channels and pipes leading to the sediment basin to dose the runoff and mix the PAM with the SS. We monitored water quality in seven sediment basins during the construction of I-540 in the Raleigh, North Carolina area over the course of three years.
Reefton's Globe Pit Holistic remediation using the 5 Fundamentals of Successful Rehabilitation
Joe Johnson, Business Development Manager - NZ DuraVeg From PGG Wrightson Turf Christchurch, Canterbury, New Zealand
The former Globe Progress Mine is located just outside of Reefton which is on the West Coast of New Zealand’s South Island. The mine is on it was way to “closure”, its restoration project is in its final years following the extensive mining practices that have now come to an end. Central to the project is the re-establishment of vital ecosystems in the post-mining landscape. The restoration areas predominately include species native to New Zealand. One of the areas located on the site yet to be fully rehabilitated is the “Globe Pit”. As the site was an open pit operation. There was 30 hectares of benches, low organic matter and limited access which would provide unique challenges to obtain vegetation. These challenges were overcome following the five fundamentals.

Consistently demonstrating to our clients, communities and regulators that HEB Construction leads the Tier 1 construction companies that build our Nation's infrastructure in delivering sound, straight forward, and efficient management of environmental performance and compliance across the vast array of environmental matters that require attention when constructing large complex projects in sensitive environments.
Experience allows me to quickly identify and direct Projects and Clients along the most effective and efficient path to address often complex hurdles and roadblocks created by conditions and constraints imposed by resource consents /Designations/wildlife permits/archaeological authorities while my strong understanding of construction methodology, constraints and implications, allows me to find the very best solution for the environment.
I am passionate about and focused on:
1. reducing planning bureaucracy and red-tape that actually has not benefit for the environment by simply ensuring the best environmental outcomes through delivery of industry best practice.
2. reducing the cost for our clients and communities of the ever growing burden of imposed obligations created by consultants who then conveniently solve these unnecessary challenges for a fee.
3. raising the standard of environmental performance within the construction industry.
4. delivering value for money to our clients and our communitiesJaime Schussler, M.S., CPESC-IT

This webinar presents the various needs for grade control measures, the types of grade control structures, how these structures dissipate the water’s energy, their pros and cons, and also presents “low head” grade control structures often used in stream restoration projects.
Two Part Series
Grade Control and Energy Dissipation - Maintaining Natural Channel Bed StabilityOn-Demand
Part 1 - Presented by: David Williams
Part 2 - Presented by: Chris Estes
Natural and human activities can cause unstable changes in stream channel slope. Natural stable stream channels utilize riffle pool sequencing to armor against erosion and dissipate energy. Riffles armor the bed from swift flows while pools dissipate the energy and slow the flow. This is called dynamic equilibrium which can take centuries to evolve. When man made activities interrupt this sequence, a chain reaction begins. Slope change in stable streams can most often result in channel incision when bedrock or similar control is not present. The end result is a streambed and base flow that is significantly lower than its natural floodplain. This in turn produces bank erosion, collapse and deposition when the deeper channel is forced to convey larger storms.
Engineered grade control measures are typically used to mitigate this interruption in stability. Grade control structures can be composed of a variety of materials and configurations such as rock, wood and earth structures placed across the channel and anchored in the streambanks. We have learned to design like nature, mimicking natural conditions and processes, like bedrock outcrops, felled trees, riffles and pools.
Part one of this two part webinar presents typical examples where grade control measures are required, the types of grade control structures, how these structures dissipate the water’s energy, their pros and cons. Part two presents research and practice of pool design for culvert outlets, erosion control and aquatic passage.
