Abandoned mine discharge; Emanates from an abandoned oil well; Located along Blacks Creek, downstream of stream point BC14.1; upstream of Porter Road and BC15 discharge. There appears to be some confusion/discrepency between sample point location maps and water quality data of discharge BC14 and BC15. There is a possibility that the water quality and flow rates have changed, but the data listed in the TMDL for BC14 and BC15 seem to be switched based upon existing monitoring. Therefore, the data listed for BC14 includes PA DEP BC15.

Abandoned Mine Discharge; located upstream of Porter Road close to road and behind the house that is located across the street from BC16 treatment system. There appears to be some confusion/discrepency between sample point location maps and water quality data of discharge BC14 and BC15. There is a possibility that the water quality and flow rates have changed, but the data listed in the TMDL for BC14 and BC15 seem to be switched based upon existing monitoring. Therefore, the data listed for BC15 includes PA DEP BC14.

AMD; Seep zone forming an AMD impacted wetland located below previous surface mine activities; Discharges to unnamed Tributary #18 near an old tree stand; BMI sampling point; Includes Beran Environmental sampling point DSCH BC7.2 which is assumed to be similar.

Abandoned Mine Discharge; Emenates from an abandoned surface mine pit; Confluences with Abandoned Mine Discharge 906-5to form unnamed headwaters tributary #18 to Blacks Creek; Upstream of 906-2 which feeds into the AMD impacted wetland; BMI sampling point

Abandoned Mine Discharge; Initially emanates at toe of spoil at base of large rock (Latitude 41.176048928 Longitude 79.931784324); Uncertain if source is underground or surface mine; Discharge seems to emanate from a more diffuse area than it appears and picks up additional mine water as it flows in channel; Starting on 12/15/15, the monitoring point location was changed to a culvert where the water discharges to and forms the stream channel. Therefore flow data before 12/15/15 may not be truly accurate especially during low flow doncidtions; Confluences with Mine Discharge 906-4 to form unnamed headwaters tributary #18 to Blacks Creek; Upstream of 906-2 which feeds portion of the AMD impacted wetland; BMI sampling point

Abandoned Mine Discharge; Possibly emanating from old deep mine or oil well; Mixes with other seeps, discharges and other
sources of water which is then sampled at 906-7A and then further downstream at 906-6; BMI sampling point

"Stream" consisting of water from various mine discharges, seeps, springs, etc. Sampled downstream of 906-7, 906-8, and 906-9 and upstream of 906-6; This point was established as an alternative to sampling every source of water on the hillside; located not far from the nearby reclaimed surface mine and old strip pit pond

Abandoned Mine Discharge; Probably emanates from an abandoned deep mine; Numerous subsidence features in vicinity; Mixes with other seeps, discharges and other sources of water which is then sampled at 906-6; BMI point

Abandoned Mine Discharge; Close proximity to 906-8; Emanates from small pond like depression; May be hydrologically connected to deep mine; Mixes with other seeps, discharges and other sources of water which is then sampled at 906-7A and then 906-6; BMI sampling point

Seep; Small alkaline iron seep near old strip mine located north of County Line road along side of unnamed tributary #17 to
Blacks Creek; Seep appears to have minimal impact to unnamed tributary #17; BMI sampling point

Abandoned Mine Discharge; Emanates along County Line Road, flows along ditch, through wetlands and enters unnamed
tributary #17 to Blacks Creek; Source may be strip mine, but uncertain; BMI sampling point

Effluent of sediment pond on reclaimed surface mine; Forms unnamed tributary #16 to Blacks Creek; Source of water includes surface runnoff as well as mine discharges 906-17 & 17b; Flow and quality quite variable; Brief heavy rain while collecting 5-17-06 sample; BMI sampling point

Abandoned Mine Discharge; Possibly from a deep mine; Flows down into and across reclaimed strip mine and mixes with
surface flow before entering sediment pond (906-16); BMI sampling point

Abandoned Mine Discharge; Located in close proximity to (~20 feet away) and probably related to 906-17; Assumed to be of
similar quality as 906-17; BMI sampling point

Abandoned Mine Discharge; Located just upstream of 906-19 along unnamed tributary #7 to Blacks Creek; BMI sampling point

Abandoned Mine Discharge; Sampled near RT58; Confluences with Abandoned Mine Discharge 906-23 to form unnamed
tributary #7 to Blacks Creek; BMI sampling point

Abandoned Mine Discharge; Sampled near Rt 58; Confluences with Abandoned Mine Discharge 906-22 to form unnamed
tributary #7 to Blacks Creek; BMI sampling point

Settling Pond located on a reclaimed surface mine; Discharge of the pond forms headwaters of unnamed tirbutary #6 to Blacks Creek; BMI sampling point

Abandoned Mine Discharge; Appears to be bubbling up from an old oil well; Flows into Blacks Creek; BMI sampling point

Unnamed tributary #18; sampled just below confluence of 906-2 and upstream of giant wetland complex; Downstream of discharges 906-4 and 906-5; Sampled as potential source water of passive system
