- W2308487926 abstract "In many situations where TMDLs need to be developed to control exceedances of water quality standards, the regulated constituents exist in a variety of chemical forms, only some of which are toxic/available. The development of TMDLs for constituents of this type requires evaluation of an appropriate TMDL goal that will protect the beneficial uses of the listed waters without significant unnecessary expenditures for constituent control. This discussion focuses on the appropriate approach for regulating copper in urban area street and highway stormwater runoff (runoff) within the TMDL framework where receiving waters for this runoff contain copper above the US EPA national water quality criterion or a site-specific water quality standard/objective. The concentrations of copper in runoff frequently exceed the US EPA national water quality criterion for fresh and marine waters for total and dissolved copper. NPDES-permitted runoff managers will, under current regulatory approaches, be required to control the copper concentrations in the runoff so that they do not cause or contribute to violations of water quality standards by any amount more than once every three years at the point of discharge for the runoff. Under the California Toxics Rule (CTR) (US EPA, 2000), copper will be regulated based on dissolved concentrations in the ambient receiving waters. If the dissolved copper, either directly or through a translator, in the runoff waters exceeds the water quality standard (objective), then the stormwater runoff can be judged to be a contrib utor to the water quality standard violation and may require a load allocation as part of TMDL implementation. Some groups, such as Sustainable Conservation (2000), are advocating that the use of copper in automobile brake pads be eliminated in order to reduce the copper in runoff. This approach is not based on an evaluation that shows that the copper present in the runoff is in a toxic/available form. It has evolved out of a mechanical comparison between the concentrations of copper in runoff to natio nal water quality criteria and state standards. From the information available, it appears that the elimination of copper from automobile brake pads will not eliminate the exceedance of the copper criterion at the point of discharge of runoff to receiving waters. A number of studies of runoff (see review by Lee and Taylor, 1999) have shown, however, that the heavy metals in this runoff are in nontoxic/non -available forms. Therefore, from the substantial evidence available, it appears that the exceedance of the national or site" @default.
