If landfills are an issue in your area, you should find the
|
||
|
following information of interest:
|
||
|
|
||
|
|
||
|
|
||
|
"Disposal of "nonhazardous" solid waste is regulated under
|
||
|
Subtitle D of the Resource Conservation and Recovery Act (RCRA).
|
||
|
These Subtitle D wastes include many different types of waste
|
||
|
streams, such as municipal solid waste, industrial waste, and oil
|
||
|
and gas waste."
|
||
|
"More than 11 Billion Tons of Subtitle D Waste Are Produced
|
||
|
Annually in the United States. Of this total more than 95 percent
|
||
|
are industrial nonhazardous waste, oil and gas waste, mining waste,
|
||
|
and municipal solid waste. Each type of waste presents unique
|
||
|
management problems and risks."
|
||
|
"There are 226,732 Subtitle D units in the United States.
|
||
|
Eighty-four percent of this total are surface impoundments, 8
|
||
|
percent are land application units, 6 percent are landfills, and 2
|
||
|
percent are industrial waste piles. Of the nearly 13,000 landfill
|
||
|
units identified, 6,584 are municipal solid waste landfill units."
|
||
|
"Shortages of Municipal Solid Waste Landfill Capacity are
|
||
|
Occurring in Some Areas of the Nation. The shortages are due to
|
||
|
several factors: (1) 83 percent of the municipal solid waste
|
||
|
generated in 1986 was landfilled; (2) 45 percent of all municipal
|
||
|
solid waste landfills will close by 1991; (3) some States have not
|
||
|
conducted long-term planning; and (4) siting of new disposal
|
||
|
facilities is difficult."
|
||
|
"Municipal solid waste landfills have degraded and may continue
|
||
|
to degrade the environment."
|
||
|
"... the data indicate that releases to the ground water from
|
||
|
municipal solid waste landfills present potential risks to human
|
||
|
health."
|
||
|
"Acute human health impacts associated with methane releases have
|
||
|
been documented."
|
||
|
"... the limited available data on industrial Subtitle D
|
||
|
facilities indicate that there is cause for concern and a need for
|
||
|
further study. Current findings include: (1) the use of design
|
||
|
controls at industrial facilities is very limited; (2) the number of
|
||
|
industrial facilities is large and the amount of industrial
|
||
|
nonhazardous waste generated annually dwarfs the amount of municipal
|
||
|
solid waste; ..."
|
||
|
"Waste tires, infections waste, and municipal waste combustion
|
||
|
ash are examples of special Subtitle D wastes. The special
|
||
|
management concerns posed by these waste streams arise from the
|
||
|
unique characteristics of these wastes. Current data are not
|
||
|
sufficient to estimate reliably the risks posed by these wastes."
|
||
|
"Federal and some State solid waste regulations lack the
|
||
|
following essential requirements: location criteria, appropriate
|
||
|
design criteria, ground-water monitoring, corrective action, closure
|
||
|
and post-closure care, and financial responsibility."

|

|
requires EPA to revise the current criteria for facilities that may
|
||
|
receive household hazardous waste or small-quantity generator
|
||
|
hazardous waste."
|
||
|
"... the Subtitle D waste stream is very diverse. Such different
|
||
|
waste types as waste tires, infectious waste, industrial
|
||
|
nonhazardous waste, and municipal solid wastes are all regulated
|
||
|
under Subtitle D of RCRA. .. the industrial nonhazardous waste
|
||
|
category includes waste from the pulp and paper industry, the
|
||
|
organic chemical industry, the textile manufacturing industry and a
|
||
|
variety of other industries."

"Each Subtitle D waste type presents unique problems and risks."

"This study estimates that there are 226,732 Subtitle D units
|
||
|
located at approximately 128,000 establishments. (An establishment
|
||
|
may have more than one unit.) Of these units, 84 percent are
|
||
|
surface impoundments, 8 percent are land application units, 6
|
||
|
percent are landfills, and 2 percent are industrial waste piles ...
|
||
|
More than half the units are oil and gas surface impoundments.
|
||
|
Municipal solid waste landfills account for nearly half of the
|
||
|
landfills and more than two-thirds of the land application units
|
||
|
are municipal sewage sludge units."
|
||
|
"Most of the Subtitle D facilities are privately owned. This is
|
||
|
because of the overwhelming number of privately owned oil and gas,
|
||
|
industrial, and mining waste facilities. In addition,
|
||
|
approximately 17 percent of municipal solid waste landfills are
|
||
|
privately owned. However, municipal solid waste landfills are
|
||
|
predominantly publicly owned. Nearly 78 percent of municipal solid

waste landfills are owned by local governments, approximately 4

percent by the Federal government, and 1 percent by State

"Approximately 83 percent of the municipal solid waste generated

in 1986 was disposed of in landfills, while only 11 percent was
|
||
|
recycled, and only 6 percent was combusted."
|

"Nearly three-fourths (74 percent) of all municipal solid waste
|

landfills are expected to close within 15 years, with 45 percent

expected to close in 5 years .... These shortages are becoming

critical in densely populated areas of the country, particularly in

the Northeast."
|
||
|
"Municipal solid waste landfills and the waste they receive have
|
||
|
been characterized reasonably well, and some impacts associated with
|
||
|
municipal solid waste landfills have been identified. However,
|
||
|
leachate and gas data for these facilities are limited."
|
||
|
"Comparatively less is known about industrial wastes and
|
||
|
facilities. Specific industrial waste streams have not been well
|
||
|
characterized and little is known about the hazards they may pose."
|
||
|
"... the data indicate that some municipal solid waste landfills
|
||
|
present potential risks to human health. Human health impacts from
|
||
|
exposure to contaminant releases to ground water from municipal
|
||
|
solid waste landfills are difficult to isolate due to the complex
|
||
|
interaction of factors that affect human health."
|
||
|
"With regard to air emissions from municipal solid waste
|
||
|
landfills, acute impacts associated with methane releases have been
|
||
|
documented. The Agency is currently determining the extent of human
|
||
|
health risks that may result from emission of volatile organic
|
||
|
compounds, which have been estimated to be in the range of 200,000
|
||
|
megagrams per year."
|
||
|
"The number of industrial facilities is very large, as is the
|
||
|
amount of waste they handle. Because current data are limited, it
|
||
|
is not possible to draw conclusions regarding the risks posed by
|
||
|
these facilities. Existing data however, do suggest that these
|
||
|
facilities need to be further investigated to determine the need for
|
||
|
additional regulatory action."
|
||
|
"Data on post-1980 facilities [solid waste landfills] are very
|
||
|
limited. (These newer sites represent only 30 percent of the
|
||
|
municipal solid waste landfills in existence today)."
|
||
|
"... on a national basis, EPA found little difference in the
|
||
|
location, design, and operation of newer municipal solid waste
|
||
|
landfills versus older landfills."
|
||
|
"Some large-quantity [hazardous waste] generators may also be
|
||
|
illegally disposing of their hazardous wastes in municipal solid
|
||
|
waste landfills."
|
||
|
"... environmental impacts and threats to human health have been
|
||
|
documented at 163 municipal solid waste landfills."
|
||
|
"Ground-water and surface water quality were adversely affected
|
||
|
at 146 and 73 municipal solid waste landfills, respectively. While
|
||
|
the impacts identified range in severity, 33 sites have contaminated
|
||
|
drinking water resources, and three other sites pose a threat to
|
||
|
water supply systems. For example, one active municipal solid waste
|
||
|
landfill has contaminated a square mile of a sole-source aquifer and
|
||
|
has closed a major community well field. ... Elevated levels of
|
||
|
organics, including pesticides, and metal contaminants have been
|
||
|
found in ground water and/or surface water at many sites."
|
||
|
"Impacts on fish or other aquatic life have been documented at 13
|
||
|
sites. ... this small number of cases does not likely reflect the
|
||
|
actual number of occurrences."
|
||
|
Superfund Statistics
|
||
|
"To be listed on the NPL [Superfund National Priorities List], a
|
||
|
site must present or be capable of presenting significant
|
||
|
environmental and/or human health impacts. Of the 850 sites listed
|
||
|
or proposed for listing on the NPL in May 1986, 184 sites (22
|
||
|
percent) were identified as municipal solid waste landfills."
|
||
|
"Halogenated organics, aromatics, and metals were found at most
|
||
|
|
||
|
|
||
|

||
|
|
||
|
|
||
|
|
||
|
|
||
|
|
||
|
|
||
|
of these sites. Releases of hazardous materials to ground water
|
||
|
were documented at nearly 75 percent of the sites. Forty-three
|
||
|
percent had releases to surface water, and 16 percent had
|
||
|
significant air emission problems."
|
||
|
Methane Damage
|
||
|
"Methane is produced in municipal solid waste landfills through
|
||
|
anaerobic decomposition of organic waste, and is explosive at
|
||
|
sufficiently high concentrations (the lower explosive limit). ...
|
||
|
where methane is not controlled, it can cause fires and explosions."
|
||
|
Ground-Water Risk Assessment
|
||
|
"To characterize typical leachate from a municipal solid waste
|
||
|
landfill, the AGency chose eight constituents from more than 200
|
||
|
chemical constituents found in municipal solid waste leachate. ...
|
||
|
The eight constituents and the effect of concern for each are as
|
||
|
follows:
|
||
|
- Vinyl Chloride human health risk (cancer)
|
||
|
- Arsenic human health risk (cancer)
|
||
|
- Iron resource damage (taste and
|
||
|
odor)
|
||
|
- 1,1,2,2,-Tetrachloroethane human health risk (cancer)
|
||
|
- Methylene chloride human health risk (cancer)
|
||
|
- Antimony human health risk (systemic
|
||
|
poisoning)
|
||
|
- Carbon Tetrachloride human health risk (cancer)
|
||
|
- Phenol resource damage (taste and odor)"
|
||
|
The analysis estimates human health risk for the maximum exposed
|
||
|
individual and the total population using ground water as a drinking
|
||
|
water source within one mile of the facility. ... Current data
|
||
|
indicate that 54 percent of existing municipal solid waste landfills
|
||
|
have no downgradient drinking water wells within one mile."
|
||
|
"For the subgroup of landfills located within one mile of a
|
||
|
drinking water well (46 percent of all landfills), nearly 40 percent
|
||
|
have risk exceeding 10(-6), with 14 percent posing risk in the 10(-
|
||
|
5) to 10(-4) range."
|
||
|
"The overall risk distribution changes significantly if it is
|
||
|
assumed that all drinking water wells are located at the facility
|
||
|
boundary (assumed to be 10 meters from the landfill unit). This
|
||
|
scenario, although certainly very conservative, helps to identify
|
||
|
the number of landfills that may contaminate the ground water
|
||
|
beneath the facility above health-based limits. Making this
|
||
|
assumption, over 67 percent of the landfills would hypothetically
|
||
|
pose risks exceeding 10(-6), with approximately 35 percent posing
|
||
|
risks in the 10(-5) to 10(-4) range."
|
||
|
"In present-value terms, the Agency estimates that resource
|
||
|
damage from municipal solid waste landfills ranges from $0 to more
|
||
|
than $4 million per site. The model predicts that nearly a third of
|
||
|
the landfills would have resource damage exceeding $200,000, and
|
||
|
about 13 percent have resource damage in excess of $1 million."
|
||
|
"The model estimates that the resulting total plume area from
|
||
|
6,000 new facilities placed in existing landfill locations would be
|
||
|
roughly 1,114 square miles (an area slightly smaller than the state
|
||
|
of Rhode Island) over the 300-year modeling period."
|
||
|
"Municipal solid waste landfills receive a variety of wastes ...
|
||
|
While the overall waste stream is considered to be less hazardous
|
||
|
than that received at RCRA Subtitle C (hazardous waste) facilities,

|
|
||
|
it nevertheless is a source of concern. By far, the majority of
|
||
|
waste disposed of at municipal solid waste landfills is household
|
||
|
waste (72 percent of the total waste stream). Household waste
|
||
|
is primarily made up of nonhazardous materials such as paper. Some
|
||
|
nonhazardous material, however may contain hazardous constituents,
|
||
|
such as, lead in newsprint. In addition, within a landfill, some of
|
||
|
these nonhazardous materials may degrade biologically and/or
|
||
|
chemically and form more toxic constituents. ... Also, about 0.35 to
|
||
|
0.40 percent of the overall household waste stream includes
|
||
|
hazardous components. Constituents of concern in household
|
||
|
hazardous waste include solvents, pesticides, other organics, acids,
|
||
|
bases, medicines, and inks ...

all the carcinogens (nine constituents) were above the health-based
|
||
|
criteria for these compounds. In a number of cases, the median
|
||
|
concentrations of all the carcinogens (nine constituents) were above
|
||
|
the health-based criteria for these compounds. In a number of
|
||
|
cases, the median concentrations would take more than a 1000-fold
|
||
|
dilution in order to meet the health criteria."

"... leachate quality tends to change over time as the landfill
|
||
|
moves through the stabilization process. However, where leachate
|
||
|
data are available for both pre- and post-1980 landfills, no trend
|
||
|
is apparent. Median concentrations for leachate from post-1980
|
||
|
landfills are higher than those for pre-1980 landfills for
|
||
|
approximately 50 percent of the constituents."
|
||
|
"Landfill gas adds to the potential for impacts from municipal
|
||
|
solid waste landfills ... Methane, which is explosive, accounts for
|
||
|
about 50 percent by volume of the total gas stream. ... trace
|
||
|
constituents (up to 2 percent) of volatile organic compounds (VOCs)
|
||
|
and toxic constituents also may be present. Toxic constituents
|
||
|
commonly found in municipal solid waste landfill gas include vinyl
|
||
|
chloride, benzene, trichloroethylene, and methylene chloride."

MSW Disposal on Indian Lands
|
||
|
"At present there are 314 Federally recognized Indian Tribes and
|
||
|
198 Alaskan Native villages in the United States covering an area of
|
||
|
approximately 87,000 square miles ... The total population of this
|
||
|
land is approximately one million. The Indian Health Service (IHS)
|
||
|
has identified 576 municipal solid waste disposal sites on Indian
|
||
|
lands."
|
||
|
"Several EPA-sponsored surveys indicate that Indian Tribes
|
||
|
perceive municipal solid waste disposal as current and future
|
||
|
environmental problem. One survey reported that on half of the
|
||
|
reservations surveyed (24) "community dumps" were used for disposal.
|
||
|
Another reported 66 open dumps on Indian lands in EPA's Region 5
|
||
|
alone. Roadside dumping and other illegal dumping were also
|
||
|
reported. Landfill leachate was cited several times by the Tribes
|
||
|
surveyed as the potential source of water pollution.
