X Project Location

A. Background – existing plant

Mahaffey, Pa

Curwensville Dam

Barnes & Tucker filed bankruptcy in 2001 – Cleans

Streams Foundation takes over operation of the

Dumans Plant

DEP explores long-term operation alternatives.

…a Win – Win Scenario

www.srbc.netwww.dep.state.pa.us

more efficient treatment needed existing pumping costs are high trust fund is limited mine pool resource recovery

agricultural consumptive use demands approx. 25 miles of stream restored allows for increased low flow releases

from the Curwensville reservoir SRBC, through a PA General Assembly

grant, will contribute $3.9 milliontowards long-term O&M.

B. Project Assessment - Inter-basin Transfer

OSM: Hawkins,Perry

x

Inter-basin Transfer (IT)

1. PA law requires projects involving IT to have a NPDES permit.

2. Assessment of watershed basins’ (Susquehanna and Ohio )

West Branch Susquehanna Ohio River Basin

> restore ~25 miles stream > BAMR commitment to treat the Red Mill, Vinton #6,

> addresses water demand issues and Wehrum discharges

> continue AML and AMD remediation projects

WHAT’S THE SOLUTION?

• Reclaim and remediate the refuse piles at Colver.

• Continue AMD remediation efforts in the South Branch Blacklick
