CDPS Permit No.: CO-0000396 Pitkin County Dear Ms Delaney, The Division has reviewed your letter of February S, 1991. It is not clear whether vour question was whether the areas described fell under the "Small Area Exemption" or if we aqreed that the sources were not point sources. There is not adequate information supplied to answer either question. In order for the Division to make a determination, a description of the area must me submitted. The tons of sediment appear low, however I do not feel comfortable making a decision on such limited information relative to the Small Area Exemption. Concerning whether such areas are non-point sources, additional information is also needed. The definition of point source is so broad that a decision may not be possible without a site visit. At a minimum a topographic map and a description of the area is needed. It should not be assumed that if an area falls under the "Small Area Exemption" it is a non-point source. It is assumed that part of the reason for your questions may be the new NPDES stormwater regulation. I have included a copy of the regulation for you information. Also included is a document which describes the industries impacted by the regulations. The last two pages discusses point sources.
