On October 5 and 19 the Chesapeake Stormwater Network in partnership with the Chesapeake Bay Foundation and the Healthy Waters Round Table offered two ½-day workshops on Inspection, Maintenance and Retrofits geared toward managers, planners and field operators on the Eastern Shore of Maryland. Both workshops covered the same technical content but were offered at two different locations to address the geographic limitations and time constraints of our workshop participants. The resources from the workshops can be downloaded below.

On February 10, 2016 the Chesapeake Stormwater Network conducted a half-day training workshop on the Inspection, Maintenance and Retrofitting of Stormwater BMPs. There were 17 people there from the Maryland Environmental Service, a quasi-public agency which inspects or maintains many BMPs across the state of MD. Below you will find the agenda and workshop resources, including the compiled slideshows that were presented that day.

This Technical Bulletin presents a visual method to assess the need for stormwater pollution practices, retrofits and stewardship at existing industrial, institutional, federal and municipal facilities. Tens of thousands of these facilities exist across the Chesapeake Bay watershed, each of which has the potential to be severe stormwater hotspots, which are defined as a site that generates higher loads of pollutants and toxics, and/or has a higher risk of leaks, spills or illicit discharges. Despite the impact of stormwater hotspots on the receiving waters of the Bay, they have not been effectively regulated or managed for several reasons.
While as many as 30,000 facilities in the Bay are technically regulated under EPA’s industrial or municipal stormwater permit programs, most individual permits do not contain specific monitoring requirements or numeric limits on effluent quality. Thus, at many sites, all that is needed to comply with the permit is to make sure you have a paper document known as a stormwater pollution prevention plan present on your site. The chances that a local or state regulator will inspect your site are vanishingly small (National Research Council, 2008). Even if sites are inspected, the permits do not require any site specific or quantitative measurements to determine whether runoff is dirty or reasonably clean, which makes it difficult to trigger enforcement actions.
A second key issue is that many property managers and environmental compliance officers simply don’t understand that much about stormwater, in comparison with more traditional environmental health and workplace safety issues they must deal with every day (e.g., hazardous waste storage and disposal and spill response). Few good training materials have been developed on site-based stormwater pollution prevention techniques, and even fewer tools exist to diagnose the actual stormwater pollution problems present at a site. Consequently, there is a strong need for a quantitative diagnostic tool to assess stormwater pollution problems and identify site-specific and cost-effective solutions.

Over the last two decades, the Chesapeake Bay states have pioneered new techniques for finding, designing and delivering retrofits to remove pollutants, improve stream health and maintain natural hydrology in developed watersheds. Several important regulatory drivers such as local MS-4 permits, local TMDLs and the Chesapeake Bay TMDL are likely to increase the amount of future stormwater retrofit implementation across the Chesapeake Bay watershed. The webcast will profile CSN’s and the Chesapeake Bay Program’s soon-to-be-released Expert Panel Final Recommendations on Retrofitting for Nutrient Reduction in the Chesapeake Bay Watershed. This training is for anyone who would like a better understanding of the newly developed retrofit crediting process.

A new publication by Water Environment & Technology (WE&T) Magazine discussing creating a market for stormwater retrofits to harness self-interest, leverage river protections, and promote sustainable development in the District of Columbia.Making Stormwater Retrofits Pay (.pdf)
“If retrofitting your property with a stormwater best management practice (BMP) paid dividends, would you do it? How about someone who’s not particularly environmentally conscious or concerned about the impacts of stormwater on local waterbodies?”

Over the last two decades, the Chesapeake Bay states have pioneered new techniques for finding, designing and delivering retrofits to remove pollutants, improve stream health and maintain natural hydrology in developed watersheds. Several important regulatory drivers are likely to increase the amount of future stormwater retrofit implementation across the Chesapeake Bay watershed. Some communities need to install retrofits to meet pollutant reduction targets under recently issued municipal stormwater permits or meet local TMDLs. In addition, each of the seven Bay states are considering greater use of urban stormwater retrofits as part of an overall strategy to meet nutrient and sediment load reduction targets for existing urban development under the Chesapeake Bay TMDL.
In the Fall of 2011, an Expert Panel was convened to review all of the available science on the pollutant removal performance and runoff reduction capability of BMPs that can be used to derive methods or protocols to derive nutrient and sediment removal rates for individual retrofits. On October 9, 2012 the final recommendations were approved by the Water Quality Goal Implementation Team! The recommendations with or without appendices can be found below. Great job to the panelists!!
Also, don’t forget to check out our newly developed Urban Stormwater Retrofits “Fact Sheet” which breaks down the practice and the expert panel recommendations into delicious bite-size pieces …yum, yum, enjoy!

Presented by the Chesapeake Stormwater Network and Center for Watershed Protection.
A combined effort between CSN and the Center for Watershed Protection with special guests from Montgomery County, MD, Arlington County, VA, and Seattle Public Utilities. This webcast introduces a retrofitting practice hierarchy and describes how to find, prioritize, and build the most effective retrofits. The webcast also discusses how much land area in a watershed can feasibly be retrofitted and at what cost based on dozens of retrofit studies conducted in urban, suburban, and rural watersheds.

Stormwater retrofitting is providing stormwater treatment on existing development that is currently untreated by any BMP or is inadequately treated by an existing BMP. Here you will find multiple resources that define stormwater retrofits, explain the process behind finding potential retrofit opportunities as well as the challenges that stormwater retrofitting may pose.

Presented by Chesapeake Stormwater Network.
Local stormwater managers will need to play a greater role in enhancing public involvement, expanding stormwater education and delivering residential stewardship practices. This webcast will focus on how local governments and watershed groups can engage the public to improve the quality of runoff from their homes and yards. The webcasts will feature the lessons learned in implementing programs to build rain gardens, disconnect roof leaders, install rain barrels and plant trees to restore the Bay. Learn about the tricks for reaching out to the public and providing meaningful incentives to motivate homeowners to keep stormwater on their property. Case studies will be featured from several local demonstration projects across the Bay watershed.

New report by the Natural Resources Defense Council on Financing Stormwater Retrofits in Philadelphia and Beyond.
The paper begins with a discussion of Philadelphia as a case study. It evaluates their new stormwater fee structure and assesses its relative ability to create a potential market for financing stormwater retrofits. The paper then goes on to discuss alternative ways to financing retrofits in the private market in Philadelphia and beyond and demonstrates how policy frameworks can play a crucial role to attracting private investors.
