Description:
This User's Guide is the result of a series of EPA sponsored research tasks to develop a procedure to investigate non-stormwater entries into storm drainage systems. A number of past projects have found that dry-weather flows discharging from storm drainage systems can contribute significant pollutant loadings to receiving waters. If these loadings are ignored (e.g., by only considering wet-weather stormwater runoff), little improvement in receiving water conditions may occur with many stormwater control programs. These dry-weather flows may originate from many sources, the most important sources may include sanitary wastewater or industrial and commercial pollutant entries, failing septic tank systems, and vehicle maintenance activities. After identification of the outfalls that contain polluted dry-weather flows, additional survey activities are needed to locate and correct the non-stormwater entries into the storm drainage systems. This User's Guide contains information to allow the design and conduct of local investigations to identify the types and to estimate the magnitudes of these non-stormwater entries. This report was submitted in partial fulfillment of contracts numbered 68-03-3255 and 68-C9-0033 and cooperative agreement CR-816862 under the sponsorship of the U.S. Environmental Protection Agency. This report covers a period from October 1, 1990 to, September 30, 1992, and work was completed as of September 30, 1992. This report was prepared under subcontract to Foster-Wheeler Enviresponse, Inc. of Edison, New Jersey, and the Urban Waste Management and Research Center of the University of New Orleans.
