Extensive sampling was conducted for all outfalls and submitted with the permit renewal application in 1992. Outfalls A through G indicated low levels or less than detectable amounts of pollutants. Based on this documentation, the State decided that stormwater sampling would only be required from Outfall 001. For ease of accessibility, this sample is taken from the manhole designated SW -I, which is immediately upstream from Outfall 001.
