The headwaters of Clearfield Creek are located inside the northern border of Cambria County, a few miles south- west of Loretto, Pa. The watershed is located on the U.S. Geological Survey 7.5 minute quadrangles of Ebensburg, Cresson, Carrolltown, Ashville, Altoona, Hastings, Coalport, Blandburg, Tipton, Westover, Irvona, Ramey, Houtzdale, Mahaffey, Curwensville, Glen Richey, Wallaceton, Clearfield and Lecontes Mills, Pa. The stream flows north-northeast from northern Cambria County into central Clearfield County, where it joins the West Branch Susquehanna River. The major tributaries to Clearfield Creek include: Roaring Run, Morgan Run, Upper Morgan Run, Muddy Run, Beaverdam Run, Powell Run, Potts Run, North Witmer Run, Brubaker Run, Little Laurel Run, Burgoon Run, Laurel Run, Bradley Run and Little Clearfield Creek. The largest municipalities include Cresson, Gallitzin, Ashville, Coalport, Irvona, Glen Hope, Madera and Clearfield. State Highway 53 travels parallel to the creek through the entire watershed, and State Highways 36, 253, 865, and 729 bisect portions of the mainstem of Clearfield Creek. Numerous township roads provide access to Clearfield Creek and its tributaries (Attachment A). 1 Segments Addressed in this TMDL The Clearfield Creek Watershed is affected by pollution from abandoned mine drainage (AMD). The AMD has caused high levels of metals and low pH in the mainstem of Clearfield Creek upstream of Clearfield, Pa. Strip mining and deep mining of bituminous coal in the watershed account for most of the AMD inputs. Muddy Run, Morgan Run, Bradley Run, Roaring Run, Brubaker Run, Little Laurel Run, Powell Run, and Upper Morgan Run are some of the larger tributaries that contribute AMD pollution to Clearfield Creek. Sanbourn Run, Blue Run and Brubaker Run have TMDLs completed for their watersheds. In 1958, the Pennsylvania Fish and Boat Commission (PFBC) surveyed Clearfield Creek and determined that the creek was highly degraded; for this reason, PFBC no longer recommended trout stocking (Trembley, 1962). In 1975, both PFBC and the Pennsylvania Department of Environmental Resources (PADER) performed investigations of the aquatic life in Clearfield Creek. The PFBC surveyed the stream from Ashville to Frugality and found that macroinvertebrate populations were depressed and noted that fish were very scarce due to AMD (Hollender, 1975). The PADER surveyed the stream in the Glen Hope area and found satisfactory water quality, but very low numbers of aquatic organisms (Hasse, 1975). An additional study was completed by Pennsylvania Department of Environmental Protection (PADEP) from 1998 to 2004 in Clearfield Creek. The study identified the larger sources of AMD and determined that water quality and macroinvertebrate populations could not recover while AMD was being produced by those sources (Spyker, 2002). Other examples of studies completed within the Clearfield Creek watershed include: The Clearfield Creek Scarlift Report completed in 1972, Muddy Run Scarlift Report complete in 1972, and Clearfield Creek Assessment Report completed in 2004. Table 1 provides a list of the impaired waters addressed by this TMDL. The stream designations for Clearfield Creek, defined by Pa. Title 25 Chapter 96, can be found in Table 2. 2 Table 1. 303(d) Listed Streams Addressed by the TMDL Segment Year Stream Stream Source Cause Miles ID Listed Name Code 990819- 1996 Clearfield Creek 26107 AMD Metals 24.3 1030-LMS 990819- 1996 Clearfield Creek 26107 AMD Metals 3.4 1020-LMS 990824- 1996 Clearfield Creek 26107 AMD Metals 7.5 1445-LMS See Attachment B, Excerpts Justifying Changes Between the 1996, 1998, 2002, and 2004 Section 303(d) lists. Table 2. Stream Designation Stream Name/Number Water Uses Exceptions To Zone County of Segments Protected Specific Criteria Clearfield Creek Main stem Clearfield WWF none Active mining operations with discharges are found in the watershed. Some permits are for remining operations that are not contributing to point source pollution because they have not created any new discharges and have not caused degradation of pre-existing discharges. The discharges in the watershed are from a combination of active and abandoned mines. Active discharges are treated as point sources and abandoned discharges are treated as nonpoint sources. The distinction between point and nonpoint sources in this case is determined on the basis of whether or not there is a responsible party for the discharge. Where there is no responsible party the discharge is considered to be a nonpoint source. Each pollutant on the 303(d) list will be addressed as a separate TMDL. These TMDLs are expressed as long-term average loadings. Due to the nature and complexity of mining effects on the watershed, expressing the TMDL as a long-term average gives better representation of the data used for calculations. A map showing the impaired waters of the Clearfield Creek Watershed is shown in Figure 1. 3 Figure 1. Impaired Waters in the Clearfield Creek Watershed 4 CLEAN WATER ACT REQUIREMENTS Section 303(d) of the 1972 Clean Water Act requires states, territories, and authorized tribes to establish water quality standards. The water quality standards identify the uses for each waterbody and the scientific criteria needed to support that use. Uses can include designations for drinking water supply, contact recreation (swimming), and aquatic life support. Minimum goals set by the Clean Water Act require that all waters be “fishable” and “swimmable.” Additionally, the federal Clean Water Act and the U.S. Environmental Protection Agency’s (USEPA) implementing regulations (40 CFR 130) require: • States to develop lists (Section 303(d) lists) of impaired waters for which current pollution controls are not stringent enough to
