Proposed Total Maximum Daily Load (TMDL) for Levittown Lake, Bucks County, PA

   The Department of Environmental Protection (Department) is holding a public meeting on Wednesday, November 15, 2000, from 3 p.m. to 5 p.m. at the Southeast Regional Office, 555 North Lane, Suite 6010, Conshohocken, PA 19428. The Department will discuss and accept comments on a proposed TMDL, established in accordance with the requirements of section 303(d) of the Clean Water Act. The Department listed Levittown Lake in 1996 and 1998 under section 303(d) of the Clean Water Act as impaired due to an excessive level of PCB found in fish tissue, resulting in the issuance of a consumption advisory. The proposed plan provides a calculation of the lake's capacity to absorb PCB without violating the water quality criterion of 0.00004 micrograms per liter. The calculated maximum amount of PCB that Levittown Lake can safely absorb under design conditions is 0.0108591 grams. The Department expects natural attenuation to, in time, reduce the concentration of PCB to an acceptable level.

   The data and all supporting information used to develop the proposed TMDL are available from the Department. To request a copy of the proposed TMDL and an information sheet, contact Allen Whitehead by phone at (610) 832-6057, by mail at 555 North Lane, Suite 6010, Conshohocken, PA, 19428, or e-mail at whitehead.allen@ dep.state.pa.us.

   The TMDL can be viewed and printed on the DEP Website, http://www.dep.state.pa.us, by typing the acronym TMDL in the direct link field, and clicking GO.

   The Department will accept written comments postmarked by November 29, 2000 at the above address. Persons who plan to make a presentation at the public meeting should notify the Department no later than 4 p.m. on Monday, November 13, 2000. The Department will consider all comments in developing the final TMDL, which will be submitted to the Environmental Protection Agency (EPA) for approval.

Proposed Total Maximum Daily Load (TMDL) for PCB and Chlordane for the Schuylkill River

   The Department of Environmental Protection (Department) is holding a public meeting on November 15, 2000 beginning at 10 a.m. and ending no later than 12 p.m. at the Southeast Regional Office, Lee Park, Suite 6010, Conshohocken, PA to discuss and accept comments on a proposed TMDL, established in accordance with the requirements of section 303(d) of the Clean Water Act. The Schuylkill River, from Felix Dam in Berks County to Fairmount Dam in Philadelphia was listed in 1996 and 1998 under section 303(d) of the Clean Water Act as impaired because excessive levels of PCB and chlordane were found in fish tissue, resulting in fish consumption advisories. The proposed plan provides calculations of the river's total capacity to absorb PCB and chlordane without violating the water quality criteria of 0.00004 micrograms per liter for PCB and 0.0005 micrograms per liter for chlordane. The maximum amount of PCB that can be safely absorbed by the Schuylkill River under design conditions is 0.00030313 lbs/day. The maximum amount of chlordane that can be safely be absorbed by the Schuylkill River under design conditions is 0.00378917 lbs/day. Remediation activities, including the excavation of stream sediments, along with bans on use and natural attenuation, are expected to reduce concentrations of PCB and chlordane to acceptable levels.

   The data and all supporting information used to develop the proposed TMDL are available from the Department. To request a copy of the proposed TMDL and an information sheet, contact Laurel Ateyeh at (610) 832-6075 or by writing to her at Department of Environmental Protection, 555 North Lane, Lee Park, Suite 6010, Conshohocken, PA 19428 or e-mail her at ateyeh.laurel@dep.state.pa.us.

Proposed Total Maximum Daily Load (TMDL) for West Branch Brandywine Creek, Chester County Business Route 30 in Coatesville to Confluence of Buck Run

   The Department of Environmental Protection (Department) is holding a public meeting on November 15, 2000 beginning at 12:30 p.m. and ending no later than 2:30 p.m. at the Southeast Regional Office, Lee Park, Suite 6010, Conshohocken, PA to discuss and accept comments on a proposed TMDL, established in accordance with the requirements of section 303(d) of the Clean Water Act. This TMDL applies to PCB and chlordane in the main stem of West Branch Brandywine Creek, from Business Route 30 in Coatesville to the confluence of Buck Run. This segment was included on the 1996 and 1998 section 303(d) lists in State Water Plan Watershed 3-H. Anglers were first advised to limit consumption of American eel downstream from Coatesville on December 12, 1979 due to a PCB concentration of 2.37 ppm, even though that value did not exceed the 5 ppm FDA action level in effect at the time. A ''Do Not Eat'' advisory was issued June 26, 1986 as part of a Statewide release due to PCB at 2.6 ppm (above the revised 2.0 ppm Action Level) and chlordane of 1.0 ppm. This advice remained unchanged until application of the Great Lakes protocol for the 1998 advisory. As a result, eels are to be eaten no more than one meal every 2 months due to PCB. The most recent chlordane data show concentrations below the Action Level (0.217 ppm in 1994 and an estimate 0.110 ppm in 1995). The proposed plan provides calculations of the stream's total capacity to absorb PCB without violating the water quality criterion of 0.00004 ug/l (micrograms per liter) for PCB and 0.0005 ug/l for chlordane . The maximum amount of PCB that can be safely absorbed by West Branch Brandywine Creek under design conditions is 0.0000231 lbs/day and chlordane is 0.0002887 lbs/day. The levels of PCBs and chlordane are expected to decline over time to acceptable levels due to bans on use, through natural attenuation, which includes flushing of sediments during periods of high stream flow and covering of contaminated sediments with newer, less contaminated materials. Natural attenuation involves less habitat disturbance/destruction than active removal, such as mechanical or vacuum dredging.

   The data and all supporting information used to develop the proposed TMDL are available from the Department. To request a copy of the proposed TMDL and an information sheet, contact William Goman at (610) 832-6074 or by writing to him at Department of Environmental Protection, 555 North Lane, Lee Park, Suite 6010, Conshohocken, PA 19428 or e-mail him at goman.william@dep.state.pa.us

   Written comments will be accepted at the above address and must be postmarked by November 29,2000. Persons who plan to make a presentation at the public meeting should notify the Department no later than 4:00 p.m. on Monday November 13, 2000. The Department will consider all comments in developing the final TMDL, which will be submitted to the Environmental Protection Agency (EPA) for approval.

Proposed Total Maximum Daily Load (TMDL) for a segment of the Shenango River

   The Department of Environmental Protection (Department) is holding a public meeting on October 27, 2000 beginning at 1:30 p.m. and ending no later than 4 p.m. at the Northwest Regional Office, 230 Chestnut St., Meadville, PA to discuss and accept comments on a proposed TMDL, established in accordance with the requirements of section 303(d) of the Clean Water Act. The Shenango River from the Shenango Lake dam (River Mile 33.1) to the mouth (River Mile 0.0) was listed in 1996 under section 303(d) of the Clean Water Act as impaired because excessive levels of PCBs and chlordane were found in fish tissue, resulting in a fish consumption advisory. The proposed plan provides calculations of the stream's loading capacity for PCBs and chlordane. The loading capacity is the greatest amount of loading that a water body can receive without violating water quality standards. The water quality criterion is 0.00004 micrograms per liter for PCBs and 0.0005 micrograms per liter for chlordane. The maximum amount of PCBs and chlordane that can enter the water column without violating the water quality criteria is 0.000099469 lbs/day and 0.001243365 lbs/day respectively. Remediation activities, which may include the excavation of stream sediments, along with bans on use and natural attenuation, are expected to reduce concentrations of PCBs and chlordane to acceptable levels.

   The data and all supporting information used to develop the proposed TMDL are available from the Department. To request a copy of the proposed TMDL and an information sheet, contact Donald Luttman at (814) 332-6685 or by writing to him at Department of Environmental Protection, 230 Chestnut Street, Meadville, PA 16335 or e-mail him at luttman.donald@dep.state.pa.us.

   Written comments will be accepted at the above address and must be postmarked by November 29, 2000. Persons who plan to make a presentation at the public meeting should notify the Department no later than 4 p.m. on October 23, 2000. The Department will consider all comments in developing the final TMDL, which will be submitted to the Environmental Protection Agency (EPA) for approval.

Proposed Total Maximum Daily Load (TMDL) for Ohio River, Monongahela River, Beaver River and Chartiers & Little Chartiers Creek

   The Department of Environmental Protection (Department) is holding a public meeting on November 14, 2000 beginning at 9 a.m. and ending no later than 12 p.m. at 400 Waterfront Drive, Pittsburgh, PA 15222 (Waterfront Rooms A & B) to discuss and accept comments on a proposed TMDL, established in accordance with the requirements of section 303(d) of the Clean Water Act.

   Segments of Ohio River, Monongahela River, Beaver River and Chartiers/Little Chartiers Creek, have been listed in 1996 and 1998 under section 303(d) of the Clean Water Act as impaired because excessive levels of PCB were found in fish tissue, resulting in a fish consumption ban. The proposed plan provides calculations of the stream's total capacity to absorb PCB without violating the water quality criterion of 0.00004 micrograms per liter. The maximum amount of PCB that can be safely absorbed (lbs/day) by each stream under design conditions is listed in the attached Table 1. Remediation activities, including the excavation of stream sediments, along with bans on use and natural attenuation, are expected to reduce concentrations of PCB to acceptable levels.
