The meeting was called to order by David Bracken, Chairman, with the Pledge of Allegiance to the flag.
Board Roll Call was taken with all three Supervisors present.
Public Comments Concerning Agenda Items:
Charles Merlo of Merlo General Contractors Inc. said they were building a treatment system for the Webster Mine discharge under contract with the US Army Corp. of Engineers. He said the job would involve building two large ponds and a wetlands taking the water from Webster from a pH of 3 which is very acidic and by the time it would discharge back into Blacklick Creek it would be 6 or 7 which is neutral. He said this would be one of the largest improvements to Blacklick Creek that the Corp. has on its agenda. Mr. Merlo said the people involved in this project are the Army Corp. in Pittsburgh, the PaDEP and that the sponsor is the Cambria County Conservation & Recreation District headed up by Dee Columbus, Executive Director. He said he was here to get the right-of-entry signed on her behalf. He said there was an outlet pipe that relieves the mine and comes out of the entry where they would have to go into. He said the flow currently is about 1500 gallons per minute. He said they had to go into that entry, build a seal and re-seal it and tap into a pipe with valves and run it under Route 271 through existing pipe placed by PennDOT and into the wetlands for the water to be improved. He said the Corp. didnít anticipate the level of the "mine pool" and that in the mid 90's there was a blow-out there and 24" pipe was placed there to fix the problem but it is about 7 feet above where they need to enter the mine. He said there had to be at least 7 feet of water or about 8 million gallons in the mine pool. He went on to say there was no risk to their knowledge to any residents in Nanty Glo but before they could get into the entrance which is totally filled with water they would have to lower it by about 10 feet to have a safe operation to install the pipe and build the seal. The idea is to relieve the water before they begin work. After looking at the old Webster Mine maps, it was determined that there were two places where they could sink bore holes and not hit a mine pillar. If a mine pillar would be hit, more than one hole would be necessary. The one location where the bore hole would go is on Jackson Township Property about 30 feet above the Nanty Glo Borough line on Loraine Road. He said the other bore hole would be on Lloyd Street. Merlo estimated it could take 6-7 months depending upon the weather. The bore holes would establish where the mine pool is and then an 18" hole would be dug down about 130 feet to the mine pool. He said the water level would then come up into the bore hole about 30 feet and a vertical surface pump would be installed with an on-site generator with a discharge line into Pergrim Run. He said there was probably about 1000 gallons a minute coming into the mine plus they had to lower the mine pool by about 8 million gallons. He said it would take about 2-4 weeks to draw down the pool and then maintain the lower level until a new seal could be built. He said they were asking for permission to go on Township Property to drill one bore hole and then an 18-24" hole to put pumps in to pump the mine down until the entry can be fixed. He added that after the work was completed, the hole would be sealed and ground would be restored to the same or better condition than before. Will Michaels said there could be a danger of roof falls and asked if there was any way to know if the mine roof was made from Sand Rock or Slate? Merlo said it may be necessary to drill multiple holes until the water came up the hole. He said the roof of the mine was down about 1608' elevation and they would be at 1780' surface elevation. He said if there was a roof fall down there it shouldnít affect the project as long as they hit an entry and the water comes up. Chairman Bracken said when talking to the Project Foreman, he was a little concerned about the water. Merlo replied if the pool was lowered, everyone working should be working in a dry, safe area.
