Using Low Impact Development to Address Heavy Metals in Stormwater Runoff at Industrial Facilities and High Density Commercial Areas

Date / Time:
Tuesday, Sep 13 11:30am to 12:00pm
Location:
Sunset I & II
Track / Session:
Industrial General Permit / No Discharge, NONAs, and Low Impact Development Strategies
Description/Abstract: 

The presentation will focus on the application of Low Impact Development (LID) design strategies, techniques, and research for industrial and high density development. The presentation will include an overview of recent guidance documents and manuals developed by the Navy for treatment of Heavy Metals, a presentation of on-going research and emerging technologies for the treatment of heavy metals being conducted by Universities and the Department of Defense, and the process of developing and implementing pilot projects that support the research and application of LID in order to meet permit requirements along coastal areas. Session participants will gain knowledge of new resources that will help them develop strategies for compliance that can be integrated into existing operations. The session is developed for compliance managers, planners and engineers, regulators, researchers, and operations personnel.

The information on the guidance documents will provide the participant with a solid foundation on how to incorporate LID non-structural and structural retrofits into existing industrial facilities with minimal or no impacts to operations. The guidance documents include extensive literature reviews, sampling and modeling techniques, fact sheets on technologies, and fact sheets and guidance on how to successfully integrate low maintenance LID designs into projects so that they can have a significant impact on pollutant load reduction. Case studies and flow charts will be used in the presentation to illustrate the use of the manuals. The information on current research will focus on several pilot projects that are being led by the University of Maryland along with several BMP research and manufacturing companies and at Navy industrial facilities and other coastal industrial facilities. The research focuses on the treatment of zinc, copper, lead, phosphorus, and total suspended solids through the use of compost based media. The existing research on the technology has shown excellent results from laboratory and field testing at inland industrial facilities. This phase of the research will be on unique industrial applications that will demonstrate the flexibility and effectiveness of media based systems. The final part of the presentation will be on how to develop pilot and research projects that can be used to demonstrate and justify the retrofit of high density urban commercial land use and parking areas with LID BMPs. Pilot and research projects are often used to demonstrate the effectiveness of LID but there are institutional and regulatory challenges for using the results to develop retrofit programs. Projects must be developed that can represent typical as well as unique conditions. Issues of replicability and the ability to scale up to the watershed level, and constructability must be considered. At the institutional level the process also needs to address procurement and contracting considerations, construction oversight, challenges associated with unforeseen conditions, and strategies to make sure LID can be incorporated across the board for new and retrofit opportunities that involve multiple organizations for implementation and maintenance. The experience and recommendations of the project team on a high density commercial area at Naval Base San Diego will be presented. This will include recommended solutions and guidance for the development of pilot and research projects that will be discussed with the audience.
