New York State’s Approach to the Remediation of Former
Manufactured Gas Plant Sites
(link at bottom)
- Introduction by
Professor Hatheway
New York State, through its
Division of Environmental Remediation, of the Department of Environmental
Conservation (NYSDEC) has, since the early 1990s, developed an outstanding
program of clean-up of Former Manufactured Gas Plants. In this undated overview
(apparently released in 2008), DEC provides the lay person with an excellent
summary of the manner in which New York State is meeting the human health and
environmental protection challenges of toxic gas manufacturing residuals and
wastes yet remaining in the ground and waters of the State.
Of the FMGPs, DEC has this to
say:
"Most towns in New York State
with populations of more than 5,000 had at least one gas plant. To date, more
than 200 MGP sites have been found statewide, and it is estimated that up to 300
may exist. Smaller MGPs also operated during this time period, providing gas for
individual factories or institutions. A trend toward regional consolidation took
hold in the 1930s, in which small town MGPs often closed and were replaced by
short-distance pipelines to neighboring plants a few miles away. As World War II
approached, longer interstate pipelines were built, making cheaper natural gas
from the Midwest more widely available. Most New York MGPs had closed by
the1950s, but a few remained in operation on standby status in areas where the
pipelines could not meet peak demand. The last MGP in New York State ceased
operations in 1972.
Of its own Lessons Learned since
the early 1990s, DEC has this to say:
"While the existence of former
MGPs was known, the potential numbers of these plants became apparent in the
early 1990s. Initially, the New York State Department of Environmental
Conservation (Department) viewed the remedial program for former MGP sites as
consisting of limited removal actions or interim remedial measures, similar to
the removal of underground petroleum storage tanks. With the passage of time the
Department’s understanding of the complexity of these sites grew, as
investigations identified the extent of the contamination problems associated
with many MGPs.
Accordingly, the Department
program was restructured. In 2000, additional staff were dedicated to the MGP
remedial program and the focus shifted from the limited removal based approach
to the more traditional Superfund site remedial approach, for nearly all MGP
sites. The process starts with a site characterization, progresses to a remedial
investigation, then to a feasibility study and continues into the design and
construction of the remedy. This approach has proven successful. Projects
continue to move forward through the remedial process, while the total number of
sites under order or agreement has increased steadily from approximately 90 to
more than 200 today.
The dedicated MGP group reflects
a recognition of the need for a consistent approach between the eight utilities
and MGP sites in general. This need is highlighted by the reality that most
utilities have sites in two or more of the Department’s regions. This group, in
addition to fostering a consistent approach and decision-making, has developed a
high level of expertise in the investigation and remediation of these sites.
Staff are frequently consulted by other states and participate in conferences
and work groups at national and international levels."

These files will be in one or more of the following formats:
"PPT":
MicroSoft Office 2003 PowerPoint - these files tend
to be quite large but will run on both
MAC and PC systems with both newer and older versions of the PowerPoint
software.
"PPTX":
MicroSoft Office 2007 PowerPoint XML file - PC only
(?) - much smaller in size than the
older PPT file format. Unfortunately they require the 2007 software in
order to view them.
"PDF":
Adobe Acrobat "Portable Document Format" file -
readable on both MAC and PC.
Files tend to be larger than PPTX and slightly smaller than PPT. Most
original special effects
will not be visible in this format. Free "Reader"
software available.
