Gain a thorough understanding of the basic elements of construction stormwater management including general permit requirements and enforcement; creating an Erosion and Sediment Control Plan (ESCP); proper sampling techniques; and the most common Best Management Practices (BMPs) in construction settings.

A Tier One Corrective Action Report must be prepared if site conditions indicate that the Stormwater Pollution Control Plan (SWPCP) is not being followed and sampling confirms that effluent benchmarks have been exceeded or if visual observations show evidence of stormwater pollution. Hear from experts responding to these Tier One corrective actions about the compliance timeline, volume reduction, treatment options, system effectiveness, and long-term strategies for staying out of trouble.

A new 1200-Z permit was issued in March and becomes effective July 1st. This session will focus on making sure you understand the most impactful changes in the permit including Tier Two corrective action requirements, numeric effluent limits, monitoring waiver eligibility, mass reduction certifications, and conducting monthly visual observations. There will also be plenty of time reserved to answer your questions.

This session will go beyond what is typically understood through guidance design manuals or treatment BMP specifications by sharing real-world case studies and hands-on experience to be used by designers and end-users alike. Whether you are looking to get more out of your existing treatment BMPs, or implementing new treatment BMPs, participate in a candid discussion on how to make common treatment BMPs more effective at industrial sites.

Tier II corrective action is triggered when effluent benchmark levels on an industrial site are regularly exceeded. Facilities facing Tier II corrective action must develop a response which requires a Stormwater Pollution Control Plan (SWPCP) and ultimately the installation of a stormwater treatment system. Panelists will present an informative set of case studies that illustrate treatment of varied, challenging, and problematic pollutants in industrial settings that are facing Tier II corrective action. Panelists will address site conditions; contaminant characterization; treatment selection process and alternatives; installation and operational results, and O&M costs.

As stormwater community decision-makers focus on incorporating sustainable, long-term solutions into ongoing stormwater management, many turn to green infrastructure and the utilization of other green resources in their projects. These techniques may take many forms and encompass a variety of disciplines in their efforts to slow down, capture, treat, or remove stormwater runoff. Speakers will demonstrate case study projects that incorporate green stormwater resources and technologies, and discuss how these integrated approaches contribute to more sustainable management of our environment.

Infiltration is a great way to manage stormwater, but it doesn’t work everywhere and poor planning, testing, analysis, and design can lead to failed infiltration systems. Speakers will present a holistic process for planning infiltration systems, then dive into the details on field testing and how field testing data can support design.

Now that infiltration has become a more common stormwater management strategy, much is being learned about the broad range of systems and installations. Panelists will present a set of case studies that delve into site assessment; system design; and construction.
Kathryn Thomason from Old Castle Infrastructure will present on deep infiltration and how Oregon’s geologic history can give us clues about where deep infiltration makes sense. She will focus on a local Portland project that utilized deep drywells and how this solution helped meet the client’s needs. The installation of the deep drywells and lessons learned from the post installation percolation test will also be discussed.
Jose Avina and Aaron Poresky from Geosyntec Consultants will discuss the use of alternative delivery methods to streamline stormwater infiltration projects. Mechanisms such as “contract manager at risk” (CMAR) can reduce the risk to project proponents, shorten timelines, and reduce costs compared to traditional design-bid-build methods. They will present a case study where distributed rain gardens and dry wells were delivered using the CMAR mechanism to capture runoff from more than 100 acres of urban land. From this project, and similar experiences, they will distill the lessons learned, how the CMAR approach improved project outcomes, and key factors in determining whether this delivery approach may be a good fit for a project.

Flooding can occur during storm events on low relief topography, and develop quickly in some cases, causing high velocity flooding which can load surface water with sediment and debris, and can sometimes take unpredictable flood paths. Traditional stormwater infrastructure has sought to contain flooding and maximize land for development, relying mainly on channelization and piped infrastructure leaving a legacy of environmental challenges and unrealized urban amenities contained within riparian corridors. This session will explore sustainable stormwater approaches involving riparian corridors as well as engineered systems designed to control stormwater peaks which support flood risk planning.

Per- and polyfluoroalkyl (PFAS) substances, sometimes referred to as “forever chemicals”, are a category of thousands of man-made chemicals (including PFOS, PFOA and GenX). These chemicals don’t break down and can accumulate over time, so their presence can be extremely persistent in the environment. Amid mounting health concerns, regulations moved swiftly in 2020 and are expected to continue in 2021 with both state-level and EPA rulemaking in progress. Speakers will discuss methods for treating PFAS in stormwater applications, including pre-treatment, activated carbon, ion exchange, and ozofractionation.

Clean Water Act lawsuits brought by citizen groups continue to be an effective enforcement tool for stormwater permit compliance. What triggers a Third-Party lawsuit? How does it begin and what’s its life cycle once it’s in motion? Join our panel of regulators and industry representatives as they shed light on causes, timing, and what you can expect if you receive a Notice of Intent (NOI).
