Implementing a SWPPP - Easy, right?

The design is complete, the permits have been obtained, and contracts are in place for contractors. It's time to get construction started! What could possibly go wrong? A SWPPP, stormwater pollution prevention plan, is a best guess about how the construction site will begin, progress and finish based upon the information that the design has before construction. However, it is rare that construction progresses as the designer envisioned. When implementing a SWPPP, expect to encounter the following: - The contractor will have a different - and possibly better - way of grading the site, along with a different construction sequence. - The unforeseen will be uncovered and it will impact the construction schedule. - Not all parties on the construction site will agree on E&SC or stormwater management for the site. When implementing the SWPPP, the inspector/site manager must adapt to these issues while still meeting the intent of all permits. SWPPP modifications. There is no perfect SWPPP. All SWPPPs will need revision and modification during construction. Some states do not require that plans be resubmitted when modifications are required. Other states do require plan submittal and approval. Know your state's requirements - and any professional requirements. In most states, professional engineers are the only people licensed to design pipes and embankments (think sediment basins and culverts). The SWPPP must reflect what's on the ground and vice versa. For example, when silt fence or check dams are removed when they are no longer needed, the SWPPP should be modified to show that these measures have been removed. Inspection documentation should also indicate that the measures have been removed and why they were removed. Together, the modified SWPPP and inspection documentation should clearly tell the story of the site conditions at the time of the inspections. Take photos of the site as well to confirm site conditions. Documentation. As the SWPPP is revised or modified, document the changes on the SWPPP sheets, in inspection reports and with photos. Documentation is critical to show compliance. The construction general permit allows time for a contractor/developer to respond to problems found on a construction site, and if the problems are resolved within that timeframe, the site is in compliance. Note that some states have additional regulations governing construction sites and off-site sedimentation can be considered a violation of the regulation, regardless of storm size. Besides SWPPP modification and inspection reports, a site manager/inspector must also keep good documentation of rain events. The Construction General Permit requires that measures be designed for the 2yr, 24hr rain event. To determine the return interval for each storm, document the time a storm started and ended and the depth of rain. That information can be compared to rainfall information provided on NOAA's Atlas 14 Point Precipitation Frequency Estimates website (https://hdsc.nws.noaa.gov/hdsc/pfds/pfds_map_cont.html) to determine the storm's return interval. Site managers/inspectors should use the rainfall data to make decisions about the failed measures. If measures failed in a storm that exceeded the 2 year storm equivalent intensity, the measures were adequate and should be reinstalled. If measures failed in a storm that was less than or equal to the 2 year storm event, the measures should be upgraded. can be compared to the rain fall information on NOAA's Atlas 13 site to determine the equivalent intensity storm. As a final good practice on a construction site, provide feedback to the designer about the site: what worked well, what didn't work well. If that information is not conveyed to the designer, the same issues may occur on other construction sites.

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.

Maintenance of Permanent Best Management Practices (BMPs)

As more permanent stormwater best management practices (BMPs) are being installed across the nation, performing ongoing maintenance has been a challenge. Permanent stormwater BMPs are now required in most urban developments across the country and it is crucial that these BMPs be maintained correctly. All permanent stormwater BMPs require regular maintenance to remain operating as designed. Maintenance has been neglected in the past due to a failure to understand who is responsible for maintenance, failure to budget for maintenance, and from a lack of knowledge on appropriate maintenance practices. In this webinar, we teach participants to recognize permanent stormwater BMPs in the field, identify maintenance needs and activities, and to perform maintenance correctly. This webinar will provide attendees a broad introduction to the needs and application of permanent stormwater BMP maintenance.

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.

Soil Health and Erosion Control

Today, more than ever, we understand the importance of soil health. Soil health is quickly becoming a topic of international concern. Internationally, lack of soil health negatively effects the quality of life in many countries due to reduced food production, decreased water quality, and increased soil erosion issues. The effects of poor soil health can be lessened or eliminated through education, awareness, and ultimately the adoption of Soil Health Best Management Practices (BMP). In this webinar, Rhett K. Kerby, M.S. will offer real world examples of soil health identifiers and discuss how Soil Health BMPs can be implemented to improve soil health and reduce erosion.

Stormwater Low Impact Development Practices • Part 1

This is part 1 of the Stormwater LIDs 2-hour course. Low Impact Development (LID) practices are Best Management Practices (BMPs) developed for managing stormwater runoff from land development sites. LIDs are used (1) to facilitate infiltration of site runoff and (2) to provide treatment of the runoff, thus improving the quality of the runoff entering the local streams and the groundwater. Many LIDs have been developed and are being prescribed by designers and installed by contractors on land development sites. Each has advantages and disadvantages that must be considered if the LID is expected to perform properly. This series will focus on the design and expected function of Bioretention Cells (Rain Gardens) and Green Roofs.
