The team discovered that they would need
to install lift stations to pump the collected
AMD to the treatment plant as opposed to
relying on a gravity-fed system. “It definitely
was not an out-of-the-box approach,” said
Cavazza. “CEC developed every spec for the
conveyance system individually.”

The Phase II design was complete in July
2007, but there was much to be done before
construction could begin, as right-of-way
and surface access had to be acquired from
28 private landowners and construction
funding needed to be lined up.

The Hollywood centralized AMD treatment
plant (named after the nearby town) went
online under the operation of the Bureau
of Conservation and Restoration in 2012.
Water is collected at 20 separate discharges
from four abandoned underground mines
and sent for treatment along nearly four
miles of conveyance lines. The plant covers
41 acres and treats an average of 4,000
gallons per minute with a design flow
capacity of approximately 7,000 gallons
per minute.

In April 2013, as part of the Pennsylvania
Fish and Boat Commission’s Cooperative
Nursery Program, 1,000 trout were stocked
in the waters upstream and downstream
from the plant for the very first time. “In less
