Controlling Turbidity: Getting Flocculation to Work on Your Site

While the US EPA has withdrawn its proposed turbidity limit on construction site runoff, there are still many states have or are proposing their own enforcement levels. Construction site owners and managers are also looking for ways to avoid public outcry and potential lawsuits over muddy water leaving their site. In most cases, typical and even more advanced erosion and sediment control practices will not prevent discharges that look like chocolate milk. This two-part seminar will explore the principles behind chemical treatments to rapidly settle suspended solids and reduce turbidity in runoff from construction sites. In the second part, he will then go over a variety of methods to apply those principles to greatly reduce turbidity. After conducting research on this subject for over 10 years in both laboratory and active construction site setting, McLaughlin has a lot of data to back up his recommendations! He will wrap up with a discussion of suggested chain of command options to avoid failures.

Erosion Control in Arid Climates

When constructing in arid environments erosion and sediment control is often overlooked. Emphasis is on dust control and wind borne erosion with erosion from water and runoff left as an after-thought all too often. In arid environments when a rain storm occurs contractors are left scrambling while being reactive and developers are left exposed to risk and unaccounted for costs. Learn how to successfully stabilize soils in areas with less than 10 inches of annual rainfall (on average), as well as how to establish vegetation in such extreme climatic conditions in a proactive manner.

Hydromodification - Causes, Effects, and Mitigation

As professionals in erosion and sediment control we are often focused on on-site erosion and sediment controls. When considering changes in runoff rates and volumes, however, it is essential to look downstream of the site to understand how changes in hydrology may adversely affect downstream receiving waters from the standpoints of degradation, aggradation, and aquatic habitat. This presentation will focus on the causes and effects of hydromodification, the roles of peak flow rates and runoff/streamflow volume, and the fundamentals of mitigating these effects. The presentation will provide examples of strategies to mitigate impacts of hydromodofication including the importance of stormwater volume reduction, control of frequently occurring events that form channels, and bed and bank stabilization.

Lessons in LID Construction

Low Impact Development (LID), an innovative stormwater management approach that treats, infiltrates, filters, and retains runoff at the source, is quickly becoming the new norm in Ontario. Construction of LID practices involves techniques and specifications that differ from traditional stormwater management construction practices. Failing to follow proper LID construction methods can result in barren bioretention landscapes, clogged infiltration practices, uneven permeable pavements, and ultimately costly post-construction repairs.

Municipal Good Housekeeping Effectiveness Utilizing Facility

Meeting MS4 Program compliance requirements for Good housekeeping & Pollution Prevention can be difficult without a well-executed plan. Conducting Municipal Facility “Hot Spot” Assessments to properly identify facility exposure to pollutant runoff risk is an effective starting point for any regulated MS4. For facilities identified as “Hot Spots”, Facility Runoff Control Plans (FRCP) can one tool used by MS4s to comply with these requirements. J.B. Dixon and Allison Sambol of Felsburg, Holt & Ullevig will discuss the genesis of the FRCP approach, and how it has been successfully implemented in several Midwest large and small MS4s. Kent Holm, Environmental Coordinator with Douglas County, Nebraska, will share his MS4 program’s successful approach to municipal facility good housekeeping by implementing FRCPs in the most populated county in Nebraska.

Permeable Pavement Design and Construction

Stormwater drainage technology has evolved to the point where it is now possible to create permeable pavements that allow stormwater drainage to occur almost immediately. The benefits to permeable pavements include having rainwater drain directly into soil, decreasing urban heating, and reducing overall stormwater runoff. This concept is gaining acceptance through studies conducted in the United States, the United Kingdom, and Australia. This webinar focuses on what constitutes permeable pavement, design tools and methodologies in designing permeable pavement, the structural and hydrological capacities, and design traffic characterization.

Post-Wildfire Remediation on Federal Lands

The wildfires of 2017 were monumental in their expanse, severity and cost to suppress- and the damage doesn't always end when the fire is put out. Loss of vegetation and fire-induced water repellent soils can trigger increased runoff which causes erosion, flooding or debris flows many miles downstream of the fire. This presentation will provide an overview of the effects of wildfires on natural resources and describe the post-fire emergency response (BAER) program implemented by the Forest Service and other federal land management agencies. Typical emergency response actions and treatment examples will be described along with examples of longer-term post fire remediation needs and costs.

Rain Water Harvesting: Applications and Maintenance

As pressure mounts on domestic water supplies and stormwater runoff from impervious surfaces becomes more of a problem, rain water harvesting can lessen pressure on water supplies and reduce stormwater runoff. Rain water harvesting has been used for centuries. In ancient Rome and Byzantium water was stored in huge underground cisterns to help walled citied withstand sieges. In climates with alternating wet and dry seasons water can be stored in cisterns to provide supply in the dry season. Rainwater harvesting can provide economical irrigation water as well as non-potable water for domestic toilet flushing, clothes washing, and car washing if plumbing codes allow.
