In the 2022 Federal CGP, the term ‘qualified inspector’ was defined to include a required minimum certification level for all sites operating under the federal CGP. To support this, the EPA has created a national certification program, and has approved other certifications that also meet this standard. Currently, some states have state-focused certifications that have been approved as meeting the new EPA standards, which allows state-based (delegated authority states) inspectors to gain greater knowledge of the NPDES permit, practices, BMPs and requirements that affect the projects they are inspecting.

Developing your eye as an inspector. A review of common BMPs, specific strengths/weaknesses, product quality considerations, proper installation, inspection, and maintenance. A practitioners perspective including quantity estimating tips.

This webinar is presented by Storm Water Solutions and the International Erosion Control Association (IECA). This webinar will present recent work to update runoff coefficients in the metropolitan Denver area within the Mile High Flood District. Many of the runoff coefficients included in local, regional, and national guidance documents were developed decades ago and do not necessarily represent current types and densities of development. This work involved analysis of recent developments to compare measured imperviousness with guidance on imperviousness that is used to calculate runoff coefficients to assess current density of developments relative to imperviousness assumptions in current criteria. We also searched the literature and performed analysis to develop criteria for runoff coefficients for different types of waterwise land cover from western desert rock mulch landscaping to landscaping with native grasses. In addition, we performed modeling analysis to evaluate the effects of disconnected impervious area and panel orientation on runoff coefficients for solar installations.

Learn the basics of an active water treatment process and how it applies to the construction industry. This presentation will review basic treatment system design standards (specific to Washington State) and give an educational overview of how a sand filtration system works. It will also cover how to properly integrate flocculants and coagulants and provide an understanding of standard treatment system configurations.

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.

Part one of this presentation will provide an overview of the Project 1007 work being conducted under the 2018 3M Settlement with the state of Minnesota. Part two will review what we know about the abundance and forms/mobility/treatability of PFAS in urban stormwater relative to emerging regulatory thresholds, and the effectiveness of source and treatment control strategies for PFAS in stormwater.

March is the month designated to celebrate women and their achievements. IECA is blessed to have some amazing women achieving amazing things in the erosion and sediment control (ERSED) industry. In this webinar you will hear from women in Australia, New Zealand and America, their work in the ERSED field, how they came to be in the industry and their vision for the future of the industry.

Following the success of the inaugural "GSI Designer Survey" conducted by Mr Woodman in 2021 engaging GSI designers up and down the east coast, a new survey was developed - the 2023 GSI Designer Survey to ask civil engineers and landscape architects engaged in GSI a series of new questions not covered by the original survey to take a deeper dive into some of the more notable results from the first survey.

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.

This presentation gives an understanding of what the Infrastructure Sustainability Council is, what makes up the ISC scoring and how the ESC industry can be involved and contribute to increased sustainability practices within their business, services and products.

This presentation will be an overview of US EPA’s Trash Free Waters (TFW) program, including program goals, TFW’s role in helping implement provisions in the Save Our Seas 2.0 Act of 2020, and a description of recently completed or active program projects.
