                RESEARCH  REPORTING SERIES

Research reports of the Office of Research and Development, U.S. Environmental
Protection Agency, have been  grouped into five series. These five broad
categories were established to facilitate further development and application of
environmental technology. Elimination of traditional grouping was consciously
planned to foster technology transfer and a maximum interface in related fields.
The five series are:

     1.    Environmental Health Effects Research
     2.    Environmental Protection Technology
     3.    Ecological Research
     4.    Environmental Monitoring
     5.    Socioeconomic Environmental Studies

This report  has  been  assigned to the ENVIRONMENTAL  PROTECTION
TECHNOLOGY series. This series describes research performed to develop and
demonstrate  instrumentation, equipment, and methodology to repair or prevent
environmental degradation from point and non-point sources of pollution. This
work provides the new or improved technology required for the control and
treatment of pollution sources to  meet environmental quality standards.

                             FOREWORD
     Man and his environment must be protected from the adverse
effects of pesticides, radiation, noise, and other forms of pollution,
and the unwise management of solid waste.  Efforts to protect the
environment require a focus that recognizes the interplay between the
components of our physical environment—air, water, and land.  The
Municipal Environmental Research Laboratory contributes to this multi-
disciplinary focus through programs engaged in

     •  studies on the effects of environmental contaminants
        on the biosphere, and

     •  a search for ways to prevent contamination and to recycle
        valuable resources.

     The Solid and Hazardous Waste Research Division contributes to
these program objectives by conducting research to promote improved
solid waste management and the environmentally safe management and
disposal of hazardous wastes.  This report presents results of an
assessment of the technical feasibility for storing nonradioactive
hazardous wastes in mined openings.

                             ABSTRACT
     This study assesses the technical feasibility of storing non-
radioactive hazardous wastes in underground mined openings.  The
results show that a majority of the wastes considered can be stored
underground in an environmentally acceptable manner if they are
properly treated and containerized.  Various mine environments in
the United States are applicable for such storage; room and pillar
mines in salt, potash, and gypsum appear to be the most favorable.
Although the underground storage and management of hazardous waste
is both technically feasible and environmentally sound, further
and more detailed research,  including an economic evaluation, is
recommended.

                              CONCLUSIONS
 1.   Storage in underground mines is an environmentally acceptable
      method of managing hazardous industrial wastes provided the re-
      commended procedures of site selection, treatment, containeriza-
      tion, and waste handling are followed.

 2.   Environmentally suitable underground space for the storage of haz-
      ardous industrial wastes now exists within the United States.

 3.   Room and pillar mines in salt, potash, and/or gypsum offer the
      most suitable containment with respect to the study criteria.

 4.   The first-level chemical interaction of storable hazardous indus-
      trial wastes with each other or with the receiving geological for-
      mations will not create any uncontrollable situations.

 5.   The potential for waste migration out of a properly selected mine
      is slight and can be controlled through proper treatment,  contain-
      erization, and site selection.

 6.   Systems adequate to detect, monitor,  and control waste migration
      can be developed from current technology.

 7.   A need for legislation concerning the storage of hazardous indus-
      trial waste in underground mines is indicated.

 8.   The design and operation of an underground storage facility for
      hazardous industrial wastes is technically feasible.

 9.   Locating regional waste storage facilities at existing mines is
      technically feasible.

10.   Additional and more detailed research is needed to close existing
      knowledge and technology gaps.   It is estimated that  such  research
      would range from 2.3 to 3.2 million dollars.

                           RECOMMENDATIONS
1.   A study of the economic feasibility of  storing and managing haz-
     ardous industrial waste in underground  mines  should be conducted.

2.   A physical and geological evaluation of the environmental suita-
     bility of each potential storage site for  hazardous industrial
     wastes should be conducted according to the criteria and tech-
     niques outlined in this study.

3.   An assessment of public attitudes,  mine owner attitudes, and en-
     vironmental impact must be conducted for each potential waste
     storage site.

4.   A detailed evaluation of the composition,  properties, treatment
     procedures, and volumes of hazardous industrial waste-streams as
     they actually occur from industry should be conducted.

5.   A study should be conducted to  determine the  best type of contain-
     erization or encapsulation to protect the  environment from any
     possible contamination resulting from handling or underground
     storage of hazardous industrial wastes.

6.   Since it was not possible within the scope of this study, to in-
     vestigate beyond the first-level chemical  interaction of the stor-
     able wastes with each other or  with the receiving geological for-
     mations, a study of all possible subsequent chain reactions should
     be conducted.

7.   Due to the unique physical nature of each  mine site, it was not
     possible to investigate the environmental  effects of waste migra-
     tion for particular sites.   Although migration is considered un-
     likely, it is recommended that  such a study be conducted.

8.   Optimum systems should be developed for detecting, monitoring,
     and controlling the wastes.

9.   If the concept of storing and managing  hazardous industrial wastes

-------
      underground is accepted,  safety and controlling legislation will
      be required.

10.   If an economic evaluation is favorable,  a demonstration facility
      should be designed,  constructed and operated to confirm operating
      principles and costs.

                               SUMMARY
The practice of using salt and other deposits to store and securely
isolate many types of industrial products,  especially hydrocarbon li-
quids and gases, has existed for over 40 years.   Absolute containment
of these products is necessitated by both economic and environmental
considerations.  Salt, potash, and gypsum are increasingly attractive
as mediums for safe, long-term isolation of environmentally hazardous
substances.  Recently, salt has been utilized as a repository for low-
level radioactive wastes and it is currently being investigated for
high-level nuclear waste storage.  In addition,  it has received at-
tention as a favorable storage medium for extremely hazardous, chem-
ical warfare munitions.

The potential for hazardous wastes stored underground to be carried
out of a mine in either air or ground water must be minimized to pro-
tect both the surface and subsurface environments.  To accomplish this,
basic criteria were established which had to be met before an accep-
table level of environmental protection could be assured.  These in-
clude:  geologic stability in and around an underground facility; hy-
drologic and surface isolation; chemical compatibility of the stored
wastes with each other and the host-medium; personnel safety under-
ground; and long-term flexibility to meet changing conditions.  The re-
sults and conclusions reached during the course of this preliminary in-
vestigation are summarized below.

Salt is widely distributed in the United States, thus risks resulting
from long distance transport of hazardous material can be reduced.  It
occurs in massive deposits and is readily mined.  In several regions
of the United States large volume underground openings presently exist.
Salt usually occurs in areas of low seismic risk and long geologic
stability.  Salt has good structural properties including high compres-
sive strength (comparable to concrete) and plasticity, which acts to
naturally heal fractures and passively relieve stress.  Salt is es-
sentially impervious and free of circulating ground water.  It is typi-
cally well isolated from all underground aquifers by adjacent thick and
impervious deposits.  Chemically, salt is compatible with nearly all of
the investigated hazardous compounds, and the few exceptions can be
treated or otherwise controlled for acceptable storage.

-------
Mined openings in salt are typically large, nearly horizontal, and
relatively stable.  Problems are rare, usually resulting from exces-
sive extraction which overloads the supporting pillars, or water leak-
age down the shafts; both are controllable using available means.
Temperature and humidity in salt openings are usually moderate and
quite stable.  The present volume of mined space existing in salt for-
mations in the United States greatly exceeds the estimated volume of
hazardous industrial wastes, and new space is constantly being created
in operating mines.

Domal salt has structural qualities similar to bedded salt but occurs
as isolated intrusions primarily in the Gulf Coast Region of the United
States.  Mines in salt domes are typically more susceptible to water
problems, both above and below the surface.

Potash salts are extensively mined in southeastern New Mexico, but
present extraction is accomplished in a manner that leaves little usa-
ble space.

Gypsum would be an excellent host-medium on the basis of chemical com-
patibility with the wastes.  However, most gypsum mines are poorly is-
olated from both the surface and near surface water.   Carefully chosen
existing mines or new mines could be sited to provide acceptable en-
vironmental protection while storing hazardous industrial wastes.

Limestone has good potential as a storage medium by virtue of the many
existing mined openings in widespread regions of the United States.
Underground limestone formations are occasionally well isolated from
ground water; but more commonly, fracture permeability and solubility
allow water to enter openings, especially in wet climatic regions.

Shales could be suitable for hazardous waste emplacement,  provided
they are low in expanding clays.  A potential benefit of shales is
their high ion-exchange capacity which acts both to limit migration
and reduce toxicity.  Shales are not commonly mined and they usually
present certain structural problems.  However, they are widely dis-
tributed, essentially impervious and commonly well isolated from
migrating ground water.

In selected areas presently lacking underground space,  new waste stor-
age mines constructed in granite are feasible.  Granite is exception-
ally strong,  and unless fractured or faulted,  is impervious to water.
Seismicity, local structure,  and present lack of mined space are the
primary limitations to its use as a host-medium for hazardous indus-
trial wastes.  Strongly acidic or basic solutions might be structurally
debilitating to granite over a long period of time.

The hazardous characteristics of wastes found to be unacceptable in the
closed confines of an underground opening include flammability,  explo-
siveness, and gas evolution.   Of the noxious wastes studied,  more than

-------
99 percent of the total volume produced can be safely stored under-
ground after treatment.  Mercury compounds had to be completely re-
jected for underground storage because their toxicity could not be
sufficiently reduced using known treatment procedures; however, it
was found that their use in industry is declining.  Five other wastes
were tentatively rejected pending additional data for evaluation.

Tables showing waste classifications by treatment and acceptability
are presented in Section 6 of this report.

Certain wastes will present less risk if stored separately; the use
of specific areas within a mine for storing compatible waste groups,
plus bulkheads and other special isolation techniques, will eliminate
potential problems of waste interaction.

Encapsulation and/or containerization will additionally insure against
waste migration or interaction, while at the same time, protecting
workers and facilitating placement and/or retrieval of the wastes.

The design and operation of an underground waste facility using se-
lected existing mines or new openings can be achieved using existing
technology.  Methods required to monitor the underground and surface
environments have been reviewed, and available instruments will pro-
vide good control over all critical factors.

Legislation will be needed to control the use and operation of an
underground facility for hazardous waste storage.

Economic studies are needed to assess the practical feasibility of
underground storage.  Such studies will have to include a detailed
cost/benefit evaluation of using either operating mines, new mines, or
abandoned mines, or combinations thereof.

By using a technical/environmental approach, the feasibility of safely
storing, controlling, and managing hazardous industrial wastes in selec-
ted underground openings has been demonstrated.  Underground space can
provide excellent waste isolation and control, with genuine protection
to the biosphere.  The potential for migration under any conceivable
circumstances is essentially eliminated by the natural characteristics
of a carefully selected underground environment.

Many other industrial wastes, which were not included in this initial
study because they were considered less hazardous to the biosphere,
might also become candidates for this type of storage after detailed
cost/risk evaluations are made.  Similarly, the acceptance of greater
risks by reducing treatment levels, less containerization, and/or
storing presently untreatable toxic wastes, could substantially alter
the economics of storing hazardous industrial wastes in mines.  Within
the limited scope of this study, alternatives such as these could not
be specifically addressed; however, this investigation does provide a
basis for development of future options.

                            INTRODUCTION
The use of underground space as a storage medium is receiving  in-
creased attention throughout the United States.  The cost-benefit  ratio
of using a mined facility versus that of a comparative surface facility
is enticing enough that both government and industry are seriously con-
sidering mined space as one answer to their storage problems.  Mined
space is presently being used for the dry storage of movie film, micro-
film, computer tapes, bank records, and civil defense commodities.  In
addition, industry presently uses mined openings for the storage of
liquefied petroleum gas, gasoline, crude oil, natural gas, and anhy-
drous ammonia.

The concept of storing hazardous wastes in mined openings is not new.
The United States Atomic Energy Commission is conducting extensive
studies into the use of underground space for the disposal of  its
radioactive wastes.  The Republic of Germany presently has a radio-
active waste disposal facility in operation at the ASSE Salt Mine in
Germany.  United States industry does not presently use this method
for disposing of its hazardous wastes because cheaper methods  are
available; however, many of these methods are environmentally  unsound.
Growing concern over possible degradation of the environment from cur-
rent disposal methods has led government to seek more acceptable ways
for industry to dispose of its hazardous wastes.  Towards this end,
Fenix & Scisson, Inc. of Tulsa, Oklahoma was awarded a contract under
the sponsorship of the United States Environmental Protection Agency
to perform an initial technical review and assessment into the use of
underground space in salt and other deposits for the emplacement of
hazardous industrial wastes.  This report contains the results of that
study.
OBJECTIVES

The primary objective of this study was to provide an assessment of
the environmental acceptability of emplacing hazardous industrial
wastes in underground mines.  In making this assessment, the following
investigations were necessary:

-------
     1.   The development of geological criteria which can be used to
          select sites providing maximum environmental protection for
          the emplacement of hazardous industrial, wastes.

     2.   The characterization of hazardous industrial wastes to deter-
          mine if they could be placed in underground mines in an en-
          vironmentally acceptable manner.

     3.   The determination of the potential for wastes to migrate from
          the mine environment.

     4.   An evaluation of the capability of existing equipment to de-
          tect, monitor, and control potential waste contamination and
          migration.

     5.   An evaluation of mine design, construction, and operating
          requirements necessary to ensure safe operation and complete
          environmental protection.

The scope of this study was to accomplish these investigations within
allotted time and fund limitations using available literature, profes-
sional experience, and expert opinions.  An economic evaluation of this
concept was not within the scope of this contract.
PHILOSOPHY OF UNDERGROUND STORAGE

The word "disposal" is often used in referring to the emplacement of
hazardous wastes in mines,  and suggests that a waste is permanently
emplaced without provision for controlling its long-term environmental
effects.  Early in this study, it was decided that a different philos-
ophy would be more consistent with the long-term protection of the en-
vironment .

The evaluations made in this study are based upon the concept of both
short and long-term storage and management of the wastes.  In the
short-term, mined storage would allow a hazardous waste to be isolated,
continually monitored, and  controlled to provide complete environmental
protection.  This protective quality of mined storage is augmented by
the ability to retrieve the containerized wastes from storage should
unacceptable conditions develop.  In the long-term, the stored wastes
may be looked upon as a potentially exploitable resource.  As changes
in technology and/or economics develop, a properly stored and managed
waste could be retrieved from a mine and recycled.  This aspect of
mined storage might permit  a facility to return some of its original
investment.

With this philosophy in mind, the storage and management of hazardous
industrial wastes in underground mines, if shown to be environmentally
acceptable and technically feasible, will provide a solution to the

-------
immediate problem of isolating hazardous wastes from  the biosphere
without jeopardizing future options or benefits.
APPROACH

To fulfill the primary objective of assessing the environmental accept-
ability of the concept, this study was divided into the following major
tasks:

     1.   Geological Characterization.
     2.   Waste Characterization.
     3.   Detection, Monitoring, and Control Technology.
     4.   Regulations Assessment.
     5.   Mine Design.
     6.   Proof-Of-Concept.

The relative organization of these tasks is outlined in Figure 1.

The study began with a concurrent review of available literature per-
taining to underground mines, subsurface disposal problems, industrial
waste streams, and current waste disposal or storage techniques.  This
literature review resulted in the identification of three major pro-
blem areas concerning waste isolation:

     1.   The physical and geological environment of an underground
          storage facility.
     2.   The chemical and hazardous nature of the wastes.
     3.   The geochemical compatibility of the wastes with mine en-
          vironments .

These aspects of hazardous waste storage in mines were considered to
be of primary concern in determining the environmental acceptability
of the concept.  However, to provide a. more realistic overall assess-
ment of the concept, it was also necessary to evaluate the following:

     1.   Detection, monitoring, and control technology.
     2.   Regulatory aspects of waste storage in mines.
     3.   Design of an underground waste facility.
     4.   A demonstration of feasibility through a proof-of-concept
          exercise.

Within the scope of this initial study, the economic aspects of this
storage concept were not directly addressed.  However,  in approaching
each area of the study, broad economic considerations were often un-
avoidable when choosing one line of investigation over another.

By an analysis of the environmental and technical problems in each of
these areas,  it will be determined if hazardous industrial wastes can
be stored underground in an environmentally acceptable manner.  Each

                     GEOLOGICAL CHARACTERIZATION
The purpose of the geological characterization was to assess the en-
vironmental suitability of underground space as a potential storage
medium for hazardous industrial wastes,  and to develop geological cri-
teria which can be used to select environmentally acceptable sites.

The literature review produced a considerable amount of relevent infor-
mation pertaining to underground disposal of radioactive wastes.  These
wastes are similar to hazardous industrial wastes because they both
require total long-term isolation from the biosphere.  Additionally,
a review was made of in-house investigations and criteria previously
developed for the storage of many liquid (and liquefied) petroleum pro-
ducts.  Other similar and related research was screened and from all of
these sources certain criteria were developed.  These criteria, if met
completely, would provide an ideal geologic environment for disposing
of hazardous industrial wastes, and were used as a basic research guide
for comparison of various geologic and mine environments.  The criteria
developed and the reasons for choosing each are listed below.

Geologic and Mine Criteria          	Reason for Selection	

Room and pillar design.             Provides maximum usable space, is
                                      easily compartmentalized, has
                                      excellent storage and transport
                                      utility, and mines of this design
                                      meet many of the other criteria.

Dry and impervious.                 Potential for adverse reactivity is
                                      sharply reduced in a dry environ-
                                      ment and potential for migration
                                      of soluble wastes may ultimately
                                      be controlled by permeability of
                                      the surrounding rock.

Structurally stable.                Structural stability is dictated by
                                      personnel safety, long term util-
                                      ity, and the need for total iso-
                                      lation.

                                    A basic  requirement of any storage
                                      site  is  that the wastes must be
                                      transported safely from their
                                      source to the facility  on  a year-

                                      above  the mined facility should
                                      be such  that necessary  above-

in order to arrive at a broad evaluation.

The basic lithologies were selected early in the study on the basis of
known characteristics and physical occurrence.   Salt, having received
the greatest previous attention as a waste disposal medium, was of pri-
mary interest.  Other evaporites (gypsum and potash) were investigated
due to their similarity, occurrence, and development.  Certain other
lithologies were selected on the basis of their proven storage poten-
tial of hydrocarbon products, geographic occurrence, minability, and
general characteristics.

Limestones were considered because they occur in many areas of the
United States, are often mined, and appeared to satisfy many of the
geologic and mine criteria.  In addition, by determining the suitabil-
ity of limestone, certain other related lithologies would also be in-
directly considered, the most important of these being dolomites which
are generally stronger, commonly mined, and widely distributed.

Shales were chosen due to their widespread occurrence and potential
for beneficial reactions (ion exchange capacity) with the wastes.  Al-
though not commonly mined, shales are generally impervious and have
been successfully used for the storage of liquid petroleum products.

Granite, as a. rock type is less uniform (homogeneous) than the other
selected lithologies, is not typically mined by room and pillar methods,
and is often associated with mountainous terrain.  On the other hand,
it is a very competent lithology, and is essentially impervious except
where locally fractured.  It is not easily weathered, which implies
little reactivity to weathering agents, occurs  in large geographic
areas and has been mined by room and pillar methods for hydrocarbon
storage.

When selecting the lithologies, it was recognized that general litho-
logic characterizations are not wholly practical or realistic, but to
best meet the study objectives certain generalizations were required.
The lithologies that have been considered in this study are believed
to be the most promising, however, this list is not restrictive and
other llthologic environments could reasonably  be added as required.

The following discussions analyze each of the selected lithologies in
detail.  An evaluation of their environmental suitability for hazard-
ous waste storage is presented at the end of this section.
SALT ENVIRONMENTS

Major salt deposits occur in many areas of the continental United
States, both as bedded units within large sedimentary basins and as
diapiric domes.  Many of the natural salt deposits have been or are
currently being mined, thus, are considered potential sites for haz-
                                  14

 ardous waste  disposal.  Figure  2  shows  the major United  States  salt de-
 posits and  salt mine  locations.
PREVIOUS  INVESTIGATIONS

Over  the  past  fifteen  to  twenty years, salt deposits have received  in-
creasing  study as possible repositories for very long-term isolation  of
hazardous (nuclear and chemical warfare) wastes.  These investigations
provide volumes of information about natural salt deposits, much of
which is  favorable to  the concept of using salt to store and isolate
hazardous wastes from  the biosphere.  Many of the conclusions reached
in  these  previous studies will be utilized in this report without elab-
oration.

Although  a majority of past research has been oriented to the problems
of  radioactive and military waste storage, the problems of storing  nox-
ious  industrial wastes are similar in that they must also be isolated
from  the  biosphere for very long times.  Furthermore, all of these
wastes have the potential to be carried in migrating ground water,  so
they must be effectively  isolated from aquifers if stored underground.
Finally,  industrial waste streams will very likely contain material
having future  economic value and thus the benefits of long-term retrie-
val must  be considered.

Salt deposits  have been prime disposal site candidates from the incep-
tion of studies conducted to evaluate underground storage of hazardous
wastes.   Certain characteristics of both bedded and diapiric salt de-
posits are very attractive when considering long term isolation.  Gen-
erally, these  can be summarized as:   stability,  strength,  impermeabil-
ity, plasticity, gross volume, and areal distribution.

The stability  of a salt deposit includes consideration of  its seismic
susceptability, faulting,  rock strength,  and rate of dissolution,  plus
any other factors bearing on its potential for future alteration.
Since the geologic environment is not static,  stability is a relative
term for  describing the rates of change for an ar^a or  formation.

Salt deposits  found in the continental United  States are typically
located in "low risk" seismic regions.   Figure 3 outlines  the major
seismic areas and fault zones in the United States.   Faulting in salt
areas is usually a local occurrence  and not directly attributable  to
large regional tectonic zones.  Bedded salt deposits are commonly  lo-
cated in large sedimentary basins which represent millions  of years of
deposition and thus exhibit  good relative  stability.  Salt domes are
associated with younger emergent land and  probably  represent  diapiric
intrusion of originally thick bedded salt  along  weak structural  zones
due to the increasing overburden pressure.   By the  nature  of  their oc-
currence,  salt domes  are more dynamic than bedded salt  deposits, but
they also  occur in areas of  low seismic risk.  Geological  investiga-

tions in the Gulf Coast region indicate that the interior domes are
older and more stable than the coastal domes, many of which may still
be actively rising.

The strength of rock salt in situ, is quite good and has been compared
to the strength of concrete.  Compressive strength values for bedded
and domal salts are consistently much greater than their tensional
strengths when tested in the laboratory.  The plastic behavior of salt
under pressure permits absorption and dispersal of strain and thus is
a very important and beneficial structural characteristic.

The rate of dissolution of salt deposits is controlled by local ground
water conditions.  By being impermeable, salt is a barrier to ground
water, yet it often occurs in proximity to water-bearing strata.  The
major underground hydrologic basins are shown in Figure 4.  The rate
of dissolution is highly variable being dependent on the rate of flow,
carrying capacity of the water (previous saturation), purity, solubil-
ity of the salt formation, etc.  Investigations to determine dissolu-
tion rates of individual salt deposits have been limited to special
area studies and indicate that the major salt deposits retreat at ex-
tremely slow rates.  Other factors which have affected the stability
of salt have resulted from mining and drilling operations.  Drill holes
that penetrate bedded salt deposits and connect aquifers above and be-
low have occasionally been known to permit migration of water with sub-
sequent dissolution of the intersected salt.  Problems that result from
man's activity can be controlled when necessary.

Rock salt is typically mined using room and pillar techniques with re-
covery ratios of 65 to 75 percent being common.  As a general rule,
the greater the recovery ratio, the less stable the mined opening.  At
greater depths, the recovery ratio is usually less because the in-
creased compressive forces of the overburden require additional support.

Mined salt deposits contain very pure sodium chloride with minor
amounts of anhydrite, related salts, and shales.  These contaminants
usually don't exceed five percent of the total composition.  Very minor
amounts of interstitial water and gases (commonly carbon dioxide or
methane) may also exist but do not cause problems in mining.  Salt
domes are generally purer than bedded salt deposits, possibly due to a
natural "refining" of the domal salt during intrusion.  Similarly,
younger coastal domes are purer than the older, and shallower interior
domes.

The purity of naturally occurring salt is in large part responsible
for its highly impermeable nature, thus is important when considering
plastic deformation which acts to close permeable openings.  In general,
contaminants reduce the plasticity of salt and act to reduce its self-
healing potential.  The inherent imperviousness of salt, whether bedded
or domed, is often enhanced by associated impermeable rock either as
discreet intervals above, below, or within bedded deposits or as a cap-
                                   18

rock over salt domes.  For this reason, a review of all surrounding
strata is an integral part of any analysis of the migration potential
of wastes which could be carried in ground water.

The long-range effects of a changing climate might result in either
increased or reduced glaciation and a subsequent rise of ocean levels.
Figure 5 shows the major salt areas which would be affected by extreme
changes in either condition.  Both changes would require thousands of
years to develop at natural rates, and thus their importance is limited
to long-range planning.

Although salt is important economically, there are huge reserves in
several areas of the United States.  The large volume of these reserves,
their widespread distribution, and their related mining operations
means that the potential storage space is enormous, economic value need
not be sacrificed, and future reserves will not be affected by the use
of space in salt for hazardous waste storage.

Conventionally Mined Salt Deposits

There are five major salt producing areas in the continental United
States that are being mined using conventional mining techniques.  For
purposes of this investigation these have been classified as:

     1.   The Appalachian Basin.
     2.   The Michigan Basin.
     3.   The northern Permian Basin.
     4.   The southern Permian Basin.
     5.   The Gulf Coast Embayment.

The Appalachian Basin, underlying parts of New York, Pennsylvania,
West Virginia, and Ohio, contains several salt beds in the Salina for-
mation of Late Silurian age.  Mining of the Salina salts is presently
conducted at three sites in west-central New York State, and at two
sites in northern Ohio.

The Michigan Basin contains contiguous Late Silurian deposits separ-
ated from the Appalachian Basin by the Findley Arch, a northeast
trending uplift extending from Ohio into Canada.  The Salina salts in
the Michigan Basin are mined conventionally at one site in the Detroit
area.  Figure 6 shows the geographic extent and major structural feat-
ures of the Appalachian and Michigan Basins.

The Permian Basin includes the Lower Permian salt bearing formations
in Kansas, southeastern Colorado, western Oklahoma, and Texas Pan-
handle, and the Upper Permian formations in southwestern Texas and
southeastern New Mexico.  The Permian salt units are conventionally
mined for salt in central Kansas, and for potash in southeastern New
Mexico.

 The  fifth major  area  having  conventionally mined  salt  is  known as the
 Gulf Coast  Embayment  which is  divided  into the  interior salt  dome re-
 gion and the  coastal  salt dome region.  The  salt  deposits throughout
 this area occur  as  diapiric  intrusions which originated from  the Louann
 salt bed, a thick unit within  the Jurassic Eagle  Mills formation.   The
 interior dome area  extends from northeastern Texas  through northern
 Louisiana to  south-central Mississippi, and  the coastal dome  area ex-
 tends from  southeastern Texas  to the Mississippi  delta.   Two  conven-
 tional salt mines are located  in Texas, and  five  mines are producing
 in southern Louisiana.

 Each of the basins will be examined in more  detail  on  the following
 pages.  Pertinent features including stratigraphy,  structure,  hydrology,
 and  seismicity will be described.

 Appalachian Basin

 The  Appalachian  Basin is composed of Paleozoic  carbonates,  evaporites,
 shales, and sandstones overlain by Pleistocene  glacial drift.  The  re-
 gional  dip  of the bedded Paleozoic deposits  is  typically  9.5 meters
 per  kilometer (50 feet per mile) to the south.  The elongated  east-west
 basin is bounded by the Adirondack uplift  in  the northeast, the Appala-
 chian structural front in the  southeast, and  the Findley Arch  in the
 northwest.  The  northern boundary is an east-west outcrop zone south of
 and  roughly parallel  to Lake Ontario.  In  central and western New York
 the  combined  thickness of the Paleozoic strata approaches 4,267 meters
 (14,000 feet)  and includes Cambrian, Ordovician, Silurian, and Devonian
 aged rocks  separated  by nonconformable contacts.

 Stratigraphy  and Structure

 The  Silurian  deposits in the Appalachian Basin include the Medina,
 Niagara, and  Cayuga series in ascending order, with the salt bearing
 Salina group within the Cayuga series.   The Salina group is composed of
 five  separate  formations which are,  from oldest to youngest:  the Pitts-
 ford  shale  (sometimes considered a top member of the Niagara Series),
 the Vernon  shale, the Syracuse salt, the Camillus  shale, and the Bertie
 limestone.   The  Salina Group in the  Appalachian Basin is up to 760 me-
 ters  (2,500 feet) thick.   Its greatest thickness is in northeastern
Pennsylvania which is near the center of the  Appalachian Basin.

The Syracuse Formation in New York ranges  from 0 to 395 meters (1,300
 feet) thick and is composed  of up to six distinct  salt units interbed-
ded with gray shales and dolomite.   The maximum aggregate  thickness of
salt approaches 275 meters (900 feet),  but individual beds are not
known to exceed a thickness  of 120 meters  (400 feet).

Structural control is not often recognized on the  surface  of the Appala-
chian Basin except near  the boundaries.   Some local anticlinal folds
and related faults occur in  the south,  but it is uncertain if  these
                                   23

-------
structures extend downward as far as the Silurian salts.  More com-
monly, the basin presents a pancake-type stratigraphy composed of both
contiguous and inter-fingered layers gently dipping and thickening to
the south.

Hydrology

Water used in the Appalachian Basin area is derived primarily from
surface sources including rainfall, streams, lakes, and reservoirs.
The annual rainfall in the basin commonly exceeds 100 centimeters (40
inches) and is sufficient to maintain several regional rivers and lo-
cal streams.  In addition to the surface water, some ground water is
obtained from local shallow wells within the glacial sands and gravels.
The water contained in the glacial drift aquifers is believed to inter-
act with deeper Paleozoic water as a single hydrostratigraphic unit.
The deeper Paleozoic rocks have low porosity and permeability values
and contain only small quantities of ground water.  The salinity of
the water generally increases with depth and the Pleistocene/Paleozoic
contact has been described as the fresh/saline water interface.  How-
ever, near the fringes of the basin where the glacial drift is thinner,
fresh water is obtained from Paleozoic aquifers and where the drift is
thickest, saline waters are found in the lower Pleistocene deposits.

The deep aquifers, including those within the Salina Formation, contain
partially to totally saturated brines with minor amounts of methane gas,
and oil.  The Silurian salts are known to have water bearing strata
above and below them, however, the normally "tight" nature of these
aquifers limits both the quantity of water and its potential to migrate.
Additionally, the thick beds of impermeable shales, anhydrites, and
salts provide an effective barrier to vertical movement.  It seems
reasonable that most short-term potential (less than 100 years) for
fluid migration lies in changes induced artificially by drilling, pump-
ing, or injection within the deep Paleozoic aquifers.  Moderate to
long-term migration (hundreds to thousands of years) is conceivable
however, and both artificial and natural processes may act to determine
its rate, direction, and carrying capacity.

Seismicity

The Appalachian Basin includes both low and moderate seismic risk areas.
The southern portion of the basin bordering the Appalachian Structural
Front is historically more active than the northern portion.  Salt
mines are located in the central area near the boundary of the low and
moderate seismic regions.  The long history of underground mining in
this area, plus the tectonically stable setting, both infer that future
seismicity will be minimal.

Michigan Basin

The Michigan and Appalachian Basins are often considered as one con-
                                   24

tiguous basin due  to  their similar  stratigraphy.  Structurally,  the
basins are  separated  by  the Findley-Algonquin arches which  together
represent a stable basement ridge that remained high during deposition
and depression of  the major sedimentary basins on either  side.

Stratigraphy and Structure

The Michigan Basin is described as  a roughly circular structural de-
pression bounded by the  Canadian Shield on the north, the Cincinnati-
Findley-Algonquin  arches from the southeast to the northeast, and the
Kankekee and Wisconsin arches on the southwest and west.  This large
sedimentary basin  is  centered near  the Saginaw Bay area of  Lake Huron
where it attains a maximum stratigraphic thickness of nearly 3,665
meters (14,000 feet).  The bedded deposits include sandstones, car-
bonates, evaporites,  and shales of  Cambrian, Ordovician, Silurian, and
Devonian ages, overlain by variable thicknesses of unconsolidated
Pleistocene glacial drift.  The Paleozoic strata normally dip at less
than one degree toward the center of the basin.  The glacial sediments
average about 75 meters  (250 feet)  thick, but locally extend down to
305 meters  (1,000  feet).

The Silurian strata deposited in the Michigan Basin includes the Ni-
agaran Series made up of the Cataract, Clinton, Lockport-Guelph, and
Salina Groups and  the Bass Island Formation.  The Cataract Group is
largely carbonates and shales with minor sandstone.   It is approxi-
mately 60 meters (200 feet) thick in the Detroit area.   The Clinton
group is composed  of  shales, carbonates, and thin sandstone, but pro-
bably does  not extend into the Detroit area since it pinches out from
the northeast to the  southwest.  The Lockport-Guelph Group  is composed
largely of  carbonates including dolomitic limestone, dolostone,  and
cherty limestone.  The thickness of the Lockport-Guelph ranges between
30 and 120  meters  (100 and 400 feet) in southeastern Michigan.

The Salina  Group is composed of seven individual members designated
A through G, from  oldest to youngest.  These units include carbonates,
halite, anhydrite, and dolomitic shale.   The A Unit  has been further
divided into two sub-units each composed of a carbonate/evaporite pair
and designated A-l and A-2.

The B Unit  is predominately salt with thin interbedded  anhydrite and
dolostone.   In the Detroit area of southeastern Michigan the B Unit is
encountered  at a depth of 340 meters (1,120 feet)  and is conventionally
mined at 345 meters (1,140 feet).   Throughout much of the Michigan
Basin the B Unit salt is found to be fairly uniform  having an average
thickness of 75 to 85 meters (240 to 275 feet).   Approaching the perim-
eter of the basin  the B Unit thins appreciably,  occurring as noncontin-
uous lenses or not at all.

The C Unit  is composed of gray/green dolomitic to sandy shale.   The
D Unit is largely salt beds separated by thin dolostone deposits.  The

E Unit is a carbonate deposit which separates the D salts from the
overlying F salt Unit.  The F Unit includes up to six distinct salt
beds separated by shales and shaly dolostones.  The F salts attain a
maximum thickness of nearly 365 meters (1,200 feet) in the central
area of the Michigan Basin.  The top Salina Unit is the G Unit composed
of dense dolostone and argillaceous dolostone.  It is sometimes con~
sidered a part of the overlying Bass Island's dolostone which is the
uppermost Silurian formation in the Michigan Basin.

The lower Devonian deposits include the Garden Island and Bois Blanc
Formations composed of interbedded limestones, dolomites, chert, and
cherty limestones.  A maximum thickness of 365 meters (1,200 feet) for
the Garden Island and Bois Blanc Formations is known in the Michigan
Basin although only a 40 meter (125 foot) thickness exists in the
Detroit area.

The Middle Devonian includes the Detroit River Group made up of the
Amherstburg sandstone and carbonates and the Lucas evaporites (salt
and anhydrite).  A thickness of approximately 115 meters (385 feet) for
this group is found in the Detroit area, but its maximum thickness
ranges up to 520 meters  (1,700 feet) in parts of the Michigan Basin.
The Dundee limestone and shale is above the Detroit River Group and
ranges from 20 meters (65 feet) thick in the Detroit area to a maximum
thickness of 135 meters  (450 feet) in the central basin.  In the De-
troit area of southeastern Michigan, the Dundee is the topmost Paleo-
zoic formation and is overlain by approximately 25 meters (75 feet) of
glacial sand and clay.  In other areas of the Michigan Basin additional
Devonian, Mississippian, Pennsylvanian, and Jurassic deposits are known
to occur.

The Michigan Basin, like the Appalachian Basin, is characterized by
sparse structural expression at the surface.  Local structures within
the regional autogeosyncline are predominately broad anticlinal folds
which trend to the northwest.  These are occasionally associated with
small displacement, high-angle, normal faults.  It is probable that
faulting of this type is more prevalent than available evidence indi-
cates, but surface expression is masked by glacial drift.

In southeastern Michigan two fault systems associated with anticlinal
folding have been described.  The first is related to the Howell Anti-
cline which trends N 50°W from the northwest corner of Wayne County
across Livingston County.  The second extends north into Michigan from
Lucas County, Ohio along the Lenawee-Monroe Anticline.  Both structures
have related high-angle normal fault zones parallel to their long axes.

Hydrology

A majority of the fresh water used in the Michigan Basin is derived
from rainfall that averages approximately 100 cm (40 inches) per year
and surface sources including the Great Lakes.  Shallow wells in gla-
                                   26

-------
 cial  sand  and  gravel,  and  surface  springs account  for  the  remaining
 fresh water  resources  of the area.

 Subsurface aquifers  are plentiful  in  the glacial sand  and  gravel  de-
 posits with  fairly large volumes and  a high recharge rate  being com-
 mon.  Contamination  of the ground water increases with depth,  and water
 below the  Pleistocene/bedrock contact is normally saline.

 Impermeable  shale and  salt beds form  natural hydraulic barriers sep-
 arating  individual water-bearing formations within the thick Paleozoic
 sequence.  Local permeability (transmissibility) between isolated aqui-
 fers  depends in large  part on the amount of drilling activity, since
 many  deep  drill holes  penetrate the basin.

 Permeable, water-bearing strata are known to exist above, below,  and
 within the Silurian  salts  over wide areas of the Michigan Basin.  Nat-
 ural  migration of deep ground water is believed to be minimal; however,
 local variations may exist.  Migration due to drilling, injection, and
 solution mining of salt probably occurs on a local basis.

 Seismicity—

 The Michigan Basin is  in a region of  low seismic activity and has ex-
 isted as a stable deposition basin for a long period of geologic  time.
 Except along local fault zones,  the possibility of extreme seismic ac-
 tivity is  remote.

 Permian  Basin

 The northern portion of the Permian salt basin underlies parts of
 southwest  Colorado, most of southwestern Kansas, northwestern Oklahoma,
 the Texas Panhandle, and extreme northeastern New Mexico.  The southern
 portion  underlies much of  southeast New Mexico and West Texas.   The
 total combined area  is approximately 193,080 sq kilometers (120,000
 square miles).  Separating the basin into northern and southern por-
 tions is largely arbitrary, based on conventional mining locations and
 the geological age differences of the mined deposits.

Northern—
  \
The northern Permian Basin contains the Lower Permian Sumner group
which includes the Hutchinson salt Member of the Wellington Formation.
Depth of burial of the salt deposit ranges  from greater than 455 meters
 (1,500 feet)  in the west to about 120 meters (400 feet) in the east.
The beds generally dip to the west at a very low angle.  The thickness
of the salt deposits is locally  variable, but generally increases  to
 the south.  The salt in west-central Kansas is approximately 90 meters
 (300 feet) thick,  while the salt in south-central Kansas often exceeds
 215 meters (700 feet) in thickness.  The purity of  the salt deposits
generally decreases as the thickness increases,  and mining operations
are limited to the purer beds in central Kansas.
                                   27

-------
Stratigraphy— The generalized stratigraphy of the Kansas Permian
Basin includes sedimentary strata ranging from Cambrian to Tertiary
geologic age, and greater than 1,830 meters (6,000 feet) in thickness.

Cambrian and Ordovician rocks overlie a metamorphic and igneous base-
ment complex composed of gneisses, schists, quartzites, and granite
plus other related rock types.  The sedimentary sequence above the
basement is predominately dolomite with some limestone and sandstone.
The aggregate thickness of this sedimentary sequence approaches 455
meters (1,500 feet), but is locally variable.

Unconformably above the Cambrian - Ordovician strata are limestones
and dolomites of Devonian and Silurian age.  These rocks are of lim*-
ited distribution with most occurrences in deep structural basins in
northeastern and south-central Kansas.

Overlying the Silurian - Devonian strata are limestones of Missis-
sippian age.  Occasionally a lower shale unit underlies this predom-
inately limestone sequence.  The Mississippian strata have a maximum
thickness of some 305 meters  (1,000 feet), but are often thinner and
separated from both the underlying and overlying strata by prominant
unconformaties.

Pennsylvanian - Permian strata constitute a thick structural unit
underlying all but the southeastern portion of Kansas.  The aggregate
thickness of these strata increases from negligible in the southeast
to over 1,830 meters  (6,000 feet) in the southwest.  The Pennsylvanian
deposits consist primarily of alternating layers of shale and lime-
stone with minor lenticular sandstone deposits and a few coal beds.
The thickness of the Pennsylvanian strata ranges from less than 305
meters (1,000 feet) to more than three times this thickness in some
areas.

The Permian strata, which contain the bedded salt deposits, are typi-
cally very thick in western Kansas and outcrop in east-central Kansas.
The lowest Permian rocks are primarily of marine origin and include
shales and limestones similar to the underlying Pennsylvanian strata.
The Early Permian strata are composed largely of red beds and evapo-
rites that were probably deposited in a shallow marine basin.  The
main salt horizons are associated with the Elaine, Stone Corral, and
Wellington formations with the conventionally mined beds occurring in
the Hutchinson Salt Member of the Wellington Formation.

The Mesozoic rocks are predominately Cretaceous in age and uncon-
formably overlie the Paleozoic strata westward from central Kansas.
The greatest thickness occurs in northwest Kansas where nearly 915
meters (3,000 feet) of Cretaceous sandstones, clayey shales, and chalky
limestones have been penetrated during drilling operations.  Older
Triassic and Jurassic deposits locally underlie the Cretaceous in south-
western Kansas.  The Triassic sediments include red beds similar to the
                                  28

-------
underlying Permian strata, while the Jurassic sediments  include  shale,
sandstone, and limestone.

Tertiary deposits are fairly widespread in Kansas with the thickest
deposits being confined to the western part of the state.  These partly
consolidated limestones, sandstones, and shales underlie unconsoli-
dated Quaternary alluvium, loess, and dune sand.

The Lower Permian salt-bearing deposits lie in a broad synclinal trough
trending to the northwest.  These deposits are typically thicker on the
limbs of the buried syncline, except where locally deposited over
structural highs associated with the Precambrian basement.  Figure 7
shows the generalized structure of Kansas.  The Permian strata outcrop
along a belt trending roughly north - south across east-central Kansas.
A thickness of approximately 915 meters (3,000 feet) of Permian strata
is exposed.  However, the salt beds, subject to relatively rapid dis-
solution, only extend to within 120 meters (400 feet) of the surface.

The greatest dissolution of the Permian Basin salts in Kansas occurs
underground along the eastern outcrop zone where the salt is retreat-
ing to the west at a rate estimated to be 10 kilometers (6 miles) every
million years.  In the west, the salt is overlain by as much as 455
meters (1,500 feet) of younger strata and dissolution is less active
along this boundary and other deep margins to the north and south.
The high salinity of rivers and streams crossing the basin is probably
indicative of dissolution occurring in thin,  noncontiguous salt beds
interspersed above the major salt deposits.

Hydrology— The Kansas Permian Basin underlies the extensive Great
Plains physiographic Province.  The surface is typically flat,  or
mildy undulating, and drainage is generally to the southeast.  Major
drainage channels include the Arkansas, Saline and Smokey Hill rivers
in western and central Kansas.  The latter two rivers originate in
western Kansas from ground water discharge and intermittent rainfall.
The annual precipitation for this area is approximately 50 to 75 centi-
meters (20 to 30 inches),  with wide variation from year to year being
common.

Potable ground water is confined to the first few hundred feet  of the
sediments, while aquifers in the deeper strata contain only brines.
The shallower aquifers are not generally contiguous and show consider-
able variation in quantity,  quality, recharge capacity,  and depth of
occurrence.  Many of these shallow aquifers are tapped locally for
domestic, livestock,  and irrigation uses.   In some areas, fresh water
from shallow aquifers has migrated downward via old wells,  resulting
in dissolution of intersected salt deposits and subsequent  surface
settlement.

The deeper aquifers occur in interbedded sandstone and carbonate de-
posits below the Quaternary and unconsolidated Cretaceous units.  The

high  salinity  of many  local  springs may  indicate  that both  the  shallow
and deep aquifers behave as  a  single hydrostatic  unit in many areas.
On a  regional  basis, the deeper aquifers are typically  isolated  from
one another by thick impermeable  shale and salt deposits.   The
greatest potential  for vertical transmissibility  lies in artificially
induced passages such  as boreholes.  Many of the  deeper aquifers are
known to have  naturally high confinement pressure which has caused
upward flow, sometimes of considerable height, in drill holes.

The Hutchinson salt bed is known  to be isolated from overlying and
underlying aquifers by very  thick impermeable shales.  The  thorough
studies performed for  the Atomic  Energy  Commission concluded that po-
tential water  problems could be created by local  commercial activities
such  as drilling, solution and conventional mining, fluid injection,
etc.  The possibility  of leaching the salt bed naturally along faults,
or by surface  erosion, dissolution, or fracturing induced by increased
overburden and crustal deformation of advancing glaciers, is remote.

Seismicity— The Permian Basin lies in the stable mid-continent region
of the United  States.  The thick  stratified sediments appear to have
been  little disturbed  since  Precambrian time.  Deposition has been
controlled by  gradual  rising and  falling of structural areas (isostatic
adjustment) and deep seated  faults or intrusions by igneous rocks are
rarely encountered.  The typically flat undisturbed bedding, plus the
low incidence  of historic seismicity, is suggestive of quiescence
and stability  over  long periods of geologic time.

Southern—

The southern Permian Basin underlies parts of southeastern New Mexico
and western Texas.  The thick Permian salt beds extend over approxi-
mately 93,290  square kilometers (36,000 square miles)  from Floyd County,
Texas in the north  to Pecos County, Texas in the south and from Mitch-
ell County, Texas in the east to Eddy County, New Mexico in the west.
The broad, shallow  salt basin is superimposed over three parallel
basement structures probably originating in Precambrian time.   Figure 8
shows the major structural features of this basin.

On the west is the deep Delaware Basin,  a structural trough extending
some  200 kilometers (125 miles) to the southeast from Carlsbad,  New
Mexico.   In general, the bedded deposits in the Delaware Basin dip
gently to the  east from their outcrop zone in the  Guadalupe Mountains.
Approximately  80 to 120 kilometers (50 to 75 miles)  east of the west-
ern boundary there is a truncated fault  zone trending  along the west
flank of the Central Basin Platform.   The deepest  parts of  the Delaware
Basin are found just to the west of this sharply uplifted plateau,  and
the total thickness of the sedimentary strata may  exceed 7,620 meters
(25,000 feet)  in this area.

The elongated Central Basin Platform probably remained high during
most of Paleozoic time as evidenced by relatively  thin overlying strata.

plus several missing intervals within the stratigraphic sequence.  The
Central Basin Platform is about 80 kilometers  (50 miles) wide and  200
kilometers  (125 miles) long.

On the east side and parallel to the Central Basin Platform is the
broad Midland Basin depositional trough.  It extends from near Lubbock
Texas, some 320 kilometers  (200 miles) to the southeast, and is typi-
cally about 95 kilometers (60 miles) wide.  The Paleozoic strata are
well represented, but their total thickness is not as great as in  the
Delaware Basin to the west.  The strata dip gently toward the center
of the trough from the east and west.  The aggregate thickness of  sed-
iments laid down in the Midland Basin exceeds 3,960 meters (13,000
feet).  Little structural control is evident except along the faulted
boundary of the central platform.

Overlying most of the eastern half of the Delaware Basin,  and nearly
all of the Central Basin Platform and Midland Basin,  plus overlapping
a shelf area to the north and east of these basins, are thick Permian
deposits including the Late Permian evaporites.  The Late Permian beds
form a very gentle synclinal trough trending to the northeast and
underlying much of western Texas and southeast New Mexico.

The northern Delaware Basin and adjacent shelf area is of primary im-
portance due to the occurrence of economic potash deposits.   Regional
control of these deposits was due primarily to extensive Permian reefs
developed on the central Basin Platform and the massive Capitan Reef
crossing the northern end of the Delaware Basin.   The Capitan Reef
structure probably acted to entrap seawater during periods when the sea
retreated southward, thus forming local evaporation basins where the
potash deposits were precipitated.   The depositional sequence was
cyclic and of long duration during much of Permian time.

Stratigraphy— The Permian System includes the Wolfcamp and Leonard
series of Lower Permian age, the Guadalupe (Capitan Reef)  of Lower to
Upper Permian age,  and the Ochoa of Upper Permian age.   The primary
evaporite deposits occur in the Upper Permian Ochoa Series which in-
cludes an extensive lower salt-bearing sequence in the Castile,  Salado,
and Rustler formations,  and a thin upper sequence in the Dewey Lake
red beds.   The aggregate thickness of the salt-bearing deposits exceeds
1,220 meters (4,000 feet) with up to 855 meters (2,800 feet)  of salt
in southeastern New Mexico.   Over much of the Permian Basin,  particu-
larly on the higher shelf areas bordering the deep Delaware and Midland
troughs,  the salts  range up from 0  to 185 meters  (600 feet)  thick.

The Castile Formation includes interbedded gray anhydrite  and  gray/
brown limestone plus thick salt beds concentrated near the middle of
the formation.  The Castile pinches out to the north of the Delaware
Basin,  but thickens to over 455 meters (1,500 feet) to the south as it
enters the depositional  trough.
                                  33

-------
The Salado Formation overlies the Castile and is the main salt-bearing
formation in the area.  The Salado Formation is composed of inter-
bedded rock salt including thin anhydrite and polyhalite units, occa-
sional thick sandstone and siltstone beds, and thin seams of claystone
underlying the evaporite units.  Approximately 305 meters (1,000 feet)
of Salado Formation is present on the north edge of the Delaware Basin
with its thickness increasing southward and decreasing to the north.

The Salado Formation has been further subdivided (informally) into the
lower salt member, the middle potassium rich zone (McNutt potash zone),
and the upper salt member.  Sylvite and related potassium and magne-
sium evaporites having economic importance are found in the middle mem-
ber.

The Rustler Formation overlies the Salado Formation and is the upper-
most salt formation of the Ochoan Series.  In the northern Delaware
Basin area it ranges in thickness from less than 60 meters (200 feet)
in the north to greater than 120 meters (400 feet) to the south.  The
salt generally occurs as discontinuous local beds within the predomin-
ately anhydrite formation.

In the mining areas of the Delaware Basin, roughly 50 kilometers (30
miles) northeast of Carlsbad, there is up to 170 meters (550 feet) of
reddish-brown siltstone and fine grained  sandstone overlying the
Rustler Formation.  Collectively these deposits are known as the Dewey
Lake Redbeds and are considered the topmost unit of the Ochoan Series.

The depth to salt varies locally, but in  general the salts are shal-
lower toward the perimeter of the Permian Basin.  The change in depth
is gradual to the north and east in the shelf and Midland Basin areas,
but is more pronounced to the west and south and elsewhere along the
boundary of the deep Delaware Basin.  The commercial potash areas of
New Mexico are on the northern margin of  the Delaware Basin with mining
operations both north and south of the buried Capitan Reef.  The depth
to commercial salt and potash formations  in this area is between 200
meters (660 feet) and 535 meters  (1,760 feet).

Overlying the Paleozoic rocks are undifferentiated Triassic rocks in-
cluding yellow-brown conglomeritic sandstone, sandstone, siltstone and
shale.  The thickness is locally variable, but from 0 to 455 meters
(1,500 feet) are known in southeast New Mexico.

Above the Triassic sediments are unconformable Cenozoic  (Pliocene)
gravels and sands, often cemented with caliche, known as the Ogallala
Formation.  A caliche "caprock" of cemented sandy limestone is also
common in this region and it ranges up to 60 meters  (200 feet) thick.

Hydrology— The Pecos River and its local tributaries provide  the
major surface drainage across  the Permian Basin of southeastern New
Mexico.  Runoff is derived from both meteoric and artesian  sources with
                                   34

-------
a  substantial portion  of  the water originating northwest and northeast
of  the  river basin  area.  Ground water recharge occurs in the Guadalupe
Mountains  to the west  and in the river and stream channels to the north-
west and northeast.

Fresh water is limited to the upper less-consolidated sediments  (Ogal-
lala and Quaternary deposits).  All ground water becomes increasingly
saline  with depth,  and along the western margin near-surface salts are
being slowly removed by dissolution.  Deeper water bearing strata are
known to overlie the Salado Formation as aquifers in the Triassic de-
posits  and the Rustler Formation.  The Triassic sandstones, the Late
Permian dolomites (Rustler Formation), and a basal conglomerate of the
Rustler Formation yield water to wells and springs.   The conglomeritic
base of the Rustler is sometimes referred to as the "brine aquifer" and
it is believed to contribute significantly to the dissolution of the
upper Salado salts.

All of  the aquifers above the Salado Formation appear to behave as a
single  hydrostatic unit over most of the basin area.   A fairly uniform
potentiometric surface, plus several dissolution features on the sur-
face (sink holes and other subsidence features),  are indicative of the
intraformational movement of ground water above the salt.  The ground
water above the commercial potash deposits migrates to the south and
southwest discharging into the  Pecos River.

The Salado Formation salts are typically nonporous and impermeable,  but
they do contain small  isolated brine and gas pockets.

Rocks underlying the thick Salado Formation are known to contain arte-
sian brines,  commonly under high hydrostatic pressure.  Most of the
known Paleozoic aquifers lie in the Capitan limestone and associated
rocks.   In the potash mining area these aquifers are  deeply buried,  as
they are in much of the southeast New Mexico and  West Texas basin area.

Dissolution of salt along the western edge of the basin has resulted
in eastward migration at a rate estimated to be 10 to 13 kilometers
(6 to 8 miles)  per million years.   At this rate,  the  evaporite deposits
presently being mined for potash are assured a future existence of at
least several million years.  Changes in such controlling factors as
diastrophism and meteorological conditions could  speedup or slowdown
the removal process.

Seismicity—  Like the northern  area of the Permian Basin,  the land in
the southern  area has been very stable.   The low-angle bedding and low
topographic relief indicate little tectonic change over a long geo-
logic period.   The last major diastrophic movement probably occurred
at the end of  Paleozoic time.   However,  gradual changes have since
occurred as depression of the basins and uplift of the plateaus.   Ad-
ditionally, the eastward rotation (downward)  of the Delaware Basin
along the western margin of  the Central Basin Platform probably con-
                                   35

tinued into Mesozoic and Cenozoic time.  There is no evidence to indi-
cate a change from the relatively stable conditions which have long
dominated the region.

Gulf Coast Embayment

All of the salt mined in the Gulf Coast region is believed to originate
from the Louann Salt bed which was probably deposited during early
Jurassic time.  The Louann salt has widespread distribution in the Gulf
Coast Region, however most of the bedded sequence is well below 1,220
meters (4,000 feet) in depth.  The salt which is commercially available
occurs as diapiric domes that have formed in response to the extreme
overburden pressure on the thick, deeply buried bedded salt.  Of the
263 known or suspected onshore salt domes, only 7 are presently being
mined using conventional methods.  Two of these mines are in Texas and
five are in Louisiana.

It has been postulated that the interior domes have essentially sta-
bilized since Miocene time, while the coastal domes are still under-
going some degree of diapiric intrusion.  Geologic and hydrologic data
are deficient in many respects despite extensive oil and gas exploration
in the region, thus evidence supporting suspected geological features
is often sparse.

Stratigraphy—

The Gulf Coast Embayment includes an immense stratigraphic sequence of
Late Paleozoic to recent sediments.  Paleozoic shale and slate have
been intersected by drill holes near the interior margins of the basin;
but toward the central and southern areas, older strata, if present,
are deeply buried under thick Mesozoic and Cenozoic sediments.  Gener-
ally speaking, the broad depositional basin is composed of thick inter-
bedded carbonates, evaporites, and elastics of marine and terrestrial
origin.  These post-Paleozoic deposits range from outcrop zones on the
interior perimeter of the embayment to an aggregate thickness estimated
to exceed 15,240 meters (50,000 feet) near the coastal regions.

Two salt horizons are known from drilling operations.  The upper salt
bed occurs in the Buckner formation of Jurassic age and ranges from
0 to 40 meters (130 feet) thick at depths from 915 to 3,050 meters
(3,000 to 10,000 feet).  The second salt bed, and what is believed to
be the "mother" salt for the salt domes, is the Louann salt of Early
Jurassic (?) age.  The Louann salt appears to be highly variable in
thickness, ranging from less than 30 meters (100 feet) to more than
915 meters (3,000 feet) in drill holes.  These extremes might repre-
sent thicker and thinner lenses within an undulating, plastic forma-
tion.

Paleozoic aged rocks outcrop in the folded mountainous zones bordering
the Gulf Coast Embayment on the northwest and northeast, and have been
                                   36

penetrated by  drill  holes  inside  the basin perimeter.  Except for the
peripheral occurrences  of  Paleozoic shale and slate, little informa-
tion about the nature of the  rocks underlying the Mesozoic and Cenozoic
strata  is presently  available due to their extreme depth.

The Eagle Mills formation  of  Early Jurassic (?) age unconformably over-
lies the Late  Paleozoic rocks, and it is composed of red shale, sand-
stone,  anhydrite,  and the  thick Louann salt.  Near the perimeter of
the embayment  in southern  Arkansas, the Eagle Mills formation is un-
conformably  overlain by Late  Cretaceous and Tertiary sediments; but
increasingly older sequences  of Jurassic and Cretaceous strata overlie
the formation  further to the  south.

Structure—

The huge regional structure described as the Gulf Coast Embayment
underlies East Texas, southern Arkansas, Mississippi, Alabama, and
Louisiana.   The gently  sloping continental basin deepens toward the
coast where  it enters the  Gulf Coast Geosyncline which forms the Gulf
of Mexico.   The Ouchita Tectonic  Belt, a zone of folded strata extend-
ing from southern  Arkansas south  across east central Texas is the
western boundary of  the embayment.  The Ouchita folding continues from
southeast Arkansas across  Louisiana into Mississippi, forming the north
and east boundary  of the salt dome basin.  A synclinal extension of the
embayment structure, without  domal salt, continues north along the
Mississippi  River  to extreme  southern Illinois.  The southern or
coastal area of the  continental structure forms the depositional rim
of the  Gulf  Coast  Geosyncline.

The Gulf Coast Embayment structure contains several significant struc-
tural features related  to  salt dome occurrences.  The salt domes which
occur in the Interior Subprovince are primarily located in three deep
synclinal basins separated by structural uplifts.  From the northwest
to the  northeast these  structures are the East Texas Syncline, the
Sabine  Uplift,  the North Louisiana Syncline,  the Monroe Uplift,  and
the broad Mississippi Dome Basin.  Each of these synclinal basins con-
tains salt domes,  and collectively, the area is known as the Interior
Dome Subprovince.  Figure  9 shows the major structural features of
the Gulf Coast Embayment.

The other major subprovince lies closer to the coast and is not known
to be controlled by  large  deep-seated tectonic structures.  Many local
anticlines and synclines do occur, and they are commonly associated
with the diapiric  salt.   Several of the coastal domes appear to be
rooted  in common anticlinal fold structures at depth, and this type
structure may  be essential to the formation of salt domes.   The other
most prevalent structures  found in the Gulf Coast area are widespread
slump faults which typically trend parallel to the coast.   These too
may be  related  to  dome  formation, but a common relationship is not
yet established.

-------
 The formation of the Gulf Coast  Geosyncline  showing  the  growth and
 genesis of salt domes has been graphically illustrated by Hanna using
 a  sequence of four cross sections  each  representing  a different stage
 of development, Figure 10.   Although  highly  idealized, Banna's model
 provides a plausible explanation for  the  interior and coastal  occur-
 rences  of domal salt.

 Recent  laboratory studies have indicated  that large  scale, short-term
 (geologically)  flow of salt  will be initiated upon reaching certain
 minimum conditions.   Given a sufficient thickness and distribution of
 salt, an overburden pressure of  82,735 kilonewtons per square  meter
 (12,000 psi)  and a temperature of  200 degrees centigrade can initiate
 vertical flow.   Once flow is started, the lower density  salt tends to
 continually feed the column  until  the source is depleted.  The salt
 plug will then  end its upward migration when its bulk density  is equal
 to the  density  of the  surrounding  strata.  Since these figures  are the
 result  of idealized  modeling,  they probably represent only part of the
 diapiric mechanism.  The extreme depth of burial of  the Louann Salt
 near the coast  makes it difficult  to  obtain information about  the
 basement structure and deep  stratigraphy which might influence  diapiric
 movement.

 The physical  dimensions of the salt domes are quite variable.   The di-
 ameter  of the domes  range up  to  several kilometers (miles)  and many
 are elongated in one direction.  In vertical section, the shapes range
 from straight to variously inclined walls with rounded,  flat,  and mush-
 room tops.  A few of the younger coastal domes intrude to the surface
 while many others are  found much deeper.  It is possible that many of
 the near surface coastal domes may have risen more than 13,715 meters
 (45,000 feet) from their source.   The interior basin domes  originated
 from a  shallower depth 4,570 meters (15,000 feet) and commonly extend
 to  within 305 meters (1,000 feet) of  the surface.

 The purity of diapiric  salt appears to reflect the vertical distance
 it  has  intruded.   In general, the older interior domes migrated ver-
 tically less  than half  the distance of the coastal domes.  The interior
 domes are typically  92  to 96 percent halite,  while the coastal domes
 range from 95 to  99  percent halite.  This difference in purity has been
 ascribed  to some  type of natural  refining during intrusion,  however,
 the actual process is yet to be explained.

Many shallow  salt  domes  are capped with single or multiple  layers of
anhydrite,  gypsum, and limestone.  Field and  laboratory  studies point
 to  caprock formation resulting from salt dissolution and subsequent
 concentration of  the insoluble constituents carried within  a salt
 diapir.    Since  this mechanism would seem to be self-limiting,  it does
not explain the  cap  rock thicknesses encountered, nor does  it  explain
 the differential  separation (layering) of the multiple lithology cap-
rocks.

-------
Hydrology—

The  Gulf  Coast  Embayment  is a  large hydrologic basin in which both
surface and  subsurface water drains generally southward toward  the
Gulf of Mexico.  The  exceptionally thick sequence of strata, including
several highly  permeable  units, allow large volumes of ground water
to migrate and/or be  contained in subsurface aquifers.

The  recharge areas  are in outcrop zones along the northern perimeter
and  along the many  major  rivers crossing the region.  Rainfall  through-
out  the recharge zone is  in excess of 100 centimeters (40 inches)  annu-
ally, and much  of this amount: undoubtedly finds its way into the per-
meable, southerly dipping strata.  Wherever the strata have been dis-
located by faulting or salt dome intrusion, ground water rises  to  the
surface under natural hydrostatic pressure.

Nearly all of the salt domes are surrounded by water saturated  strata,
often extending to  very great depths and typically quite permeable.
The  hydrologic  setting of every salt dome is unique and in most cases,
despite extensive drilling, information is sparse.

Many salt domes are expressed on the surface as depressed basins which
often contain standing water.   In addition, the overlying sediments
and/or certain units  in the caprock,  are porous,  permeable,  and sat-
urated and this has often caused problems when sinking mine shafts.

The  primary water problem in salt dome mines has historically centered
on water  leakage around the shaft openings.  In a few cases,  the
resulting dissolution has caused the loss of entire mines when uncon-
trolled flooding occurred.

Other major water problems encountered in salt domes result  from large
lenses of water-bearing sandstone which occasionally occur as inclu-
sions within  the salt.  These miniature reservoirs have been known to
discharge significant amounts of water under pressure when encountered
in mines.  Finally,  the potential for rapid flooding is inherent in
the  confined  area of any salt  dome surrounded by permeable saturated
strata.   Penetration of the impervious dome wall,  by whatever means,
can  provide an entry for water, thus the need for excellent  control
when mining near the perimeter often exists.

A long range water  problem which might affect a large portion of the
present Gulf  Coast  area is related to a change in sea level.   If the
present polar ice undergoes appreciable melting,  the subsequent rise
of sea level would  inundate much of  the Gulf Coast Region.   The poten-
tial for  such a sea  level change is  probably not  significant  for short-
term storage  operations,  but might pose a potential hazard hundreds or
thousands of years  from now.
                                  41

-------
Seismicity—

The Gulf Coast region is characterized by low seismic activity during
the historic past.  Two areas of the basin, one in eastern Texas and
the other along the coast of southern Mississippi, are in no-damage
zones of the Seismic Risk Map of the United States.  The remaining
area of the Gulf Coast Embayment is in a zone of low seismic risk.

Local and regional tectonic features are normally attributed to rapid
sediment deposition and salt intrusion, and consist of slump faults
and graben structures.  The seaward migration of the depositional ba-
sin has resulted in zones of down faulting on the landward side.  These
slump fault systems typically trend east-west parallel to the regional
strike.  The salt diapirs commonly exhibit local faulting radiating
away from the domes.

Historically the Gulf Coast Embayment is very stable, while geologi-
cally the area has apparently undergone no major diastrophic change
during a long period of deposition.  This implies that the seismicity
of the region has probably been low, and should remain low for a long
time to come.
OTHER ENVIRONMENTS

Other lithologic environments including gypsum, potash, shale, lime-
stone, and'granite are briefly described on the following pages.

Gypsum

Gypsum, like salt, is an  evaporite mineral deposited during periods of
ocean retreat when basin  catchments held and concentrated saline water
by evaporation.  Over a long period of time, the increasingly concen-
trated minerals fell out  of solution, forming the large evaporite de-
posits.

Gypsum is commonly associated with the other evaporite minerals and
occurs as very pure discreet beds or mixed with anhydrite.  Economic
deposits occur within the evaporite sequences of the major sedimentary
basins and  in the cap rock formations over many salt domes.

The major value of gypsum is derived from its use as plaster and in the
manufacture of wallboard.  It can be described as a large volume, low
value product requiring high purity and easy access to be profitably
exploited.  Due to a combination of its economics and mode of occur-
rence, most gypsum is mined by open-pit methods.  The few underground
room and pillar mines which do exist are typically less than 90 meters
 (300 feet)  deep; however,  they often include a large volume of mined
space.
                                   42

-------
As  a waste storage medium,  gypsum  is  in some respects  superior  to
other rock types.   It  is  essentially  impervious to water,  insoluble,
deforms  plastically, and  is generally nonreactive.  In addition, it  is
widely distributed and easily  excavated, and is often  associated with
other impermeable  rock sequences.

On  the negative  side,  present  mining  operations do not lend themselves
to  waste storage.   The commonly shallow workings are likely to  have
water problems unless  located  in arid regions.  Near-surface deposits
are often interbedded  with  carbonate  and shale deposits due to  dissolu-
tion or  decay of other less resistent evaporites.  Roof and floor con-
trol of  the underground openings is usually maintained in proximity  to
these adjacent sedimentary  rocks,  and consequently the size of  opening
is  limited and the potential for roof falls along shale partings is
increased.

In  summary,  gypsum is  an  excellent rock medium for hazardous waste
storage.   However,  the use  of  current mining operations are question-
able for this purpose  due to stability problems and shallow depths.
Deeper mines, engineered  for stability, could be excellent waste re-
positories.

Potash

Potash is produced  from several mines in southeastern New Mexico.  The
important economic  occurrences are within the thick Permian salt de-
posits as relatively thin discrete beds.  The high concentration of
potassium salts  (potash)  is  a consequence of unique climatic and sa-
linity conditions resulting  in increased precipitation of these salts.
Additional  concentration by  replacement and redeposition may also have
occurred.

The potash bearing  beds extend over thousands of square kilometers, but
are not  contiguous  over large areas.  The deposits are interbedded
through  more  than a hundred meters (1,000 feet) of vertical depth,
and most mines operate  from depths of 215 to 520 meters (700 to 1,700
feet).

Halite and  potash salts are  so similar that properties of salt can, for
all practical purposes, be taken to include potash.  The physical char-
acteristics,  including  plasticity,  strength, structure, permeability
and solubility are  essentially the same.

Potash has  a higher economic value than halite, and this is reflected
in  the mining methods employed.  Room and pillar designs are commonly
used;  however, the  extraction ratios are high,  approaching 90 percent.
This high ratio is achieved  by methodically "robbing"  the pillars so
that the roof collapses under controlled conditions.   The obvious re-
sult of  this mining method is that the remaining space is limited to
haulageways.
                                   43

-------
On the basis of geologic properties, potash appears to be a good stor-
age medium for hazardous chemical wastes, but present mining methods
result in a limited volume of underground space being available.

Shale

Shale is a rock medium in which mined openings for the emplacement of
hazardous wastes could be constructed.  The desirable criteria of
shale are its very low permeability, high ion exchange capacity, mod-
erate plasticity, and wide distribution.

Shale is a laminated sedimentary rock in which the constituent parti-
cles are predominantly clay size.  The average composition of shale is
59 percent clay minerals, 20 percent quartz and chert, 8 percent feld-
spar, 7 percent carbonates, 3 percent iron oxides, 1 percent organic
material, and 2 percent other.  The common clay minerals in shale are
illite, chlorite mica, montmorillonite, and kaolinite.  The very low
permeability of shales would minimize the movement of ground water into
or out of underground openings.  The average porosity of shale is about
13 percent.  In areas of intense deformation of the strata, secondary
permeability resulting from fractures would be higher than the original
shale permeability and should be avoided.

The greatest potential benefit of  storage in shales is the high ion
exchange capacity of these rocks,  which may neutralize waste toxicity
or otherwise limit their migration from the area of emplacement.  The
relatively high plasticity of most shales will also tend to prevent the
movement of waste material from an emplacement site because of its
natural tendency to close minor openings.

Shales are very widely distributed in the earth's  crust.  Sedimentary
rocks underlie about 75 percent of the total land  area of the earth
and approximately 42 to 56 percent of the sedimentary rocks are shales.
Figure 11 indicates those areas of the United States that are underlain
by thick bodies of shale.  Table 1 lists and identifies the important
shale deposits of the United States.

The difficulties of constructing underground openings in shale are
increased by the tendency of the rock to separate  along bedding planes,
and the inclusion of swelling clays such as montmorillonite.  Montmo-
rillonite is abundant in the Mesozoic and Cenozoic sedimentary rocks
of the United  States but rare in the  pre-Mesozoic  rocks.  However, rel-
atively stable openings can be constructed in  shale as shown by the
existence of several underground caverns that  have been mined for the
storage of  liquid petroleum products  in  shale  deposits.

Thick sequences of shale in areas  of  minor or  no  seismic risk,  and
 suitable for underground storage facility construction, occur in many
parts of the United States.  Occasional variations in sedimentation
 sometimes result in interbedded  sandstone or limestone units  to produce
                                   44

-------
locally unacceptable permeability conditions within a generally favor-
able lithologic unit.

Limestone

Limestone can be considered as a potential storage medium due to its
widespread occurrence and exploitation.  Many limestone mines, in-
cluding cement and lime, exist throughout the United States.

Limestone is subject to water dissolution in wet climates which re-
sults in many caverns, sinks, and open water channels.  Therefore, in
these areas its utility for mined storage may be severly limited.  In
arid regions, dissolution is less active although long-term changes
in meteorologic conditions could alter this situation.

The physical characteristics of limestone rock often make it a favor-
able mined medium.  Thick, massive, and widespread deposits are com-
mon in major sedimentary basins and provide very stable openings where
not faulted or fractured.  Water migration typically occurs along
jointed, fractured, and faulted zones.  Limestone is reactive to acid
solutions and this may be a potential problem for its use as a waste
storage medium.

The volume of mined space in limestone is enormous; however, many mines
are relatively close "to the surface.   It seems probable however,  that
a few of these sites will be found suitable for waste storage.

Granite

Another rock medium in which mined space could be created for the stor-
age of hazardous wastes is intrusive igneous rock such as granite.  The
major reasons that granite-type igneous rocks can be considered are
their low permeabilities and high mechanical strength.

The permeability of granites is low due to the manner in which igneous
rocks are formed.  These rocks are formed by the cooling and solid-
ification of a molten rock mass that invades the earth's crust, but
does not reach the surface.  Because of high confining pressures, very
little void space is created in the rock as it solidifies, with the
average porosity of a medium-grained granite being about 1.6 percent.

Secondary permeability resulting from fractures and joints can, however,
be a significant problem in intrusive igneous rocks.  The fractures
and joints are a result of stresses created in the rock as it solidi-
fies and from local tectonic forces.   In some areas, ground water could
enter the mine openings through the interconnected fractures and
joints, but various sealing techniques can be used to control this type
of water inflow.

The high mechanical strength of intrusive igneous rock facilitates the
                                   53

-------
construction of very stable underground openings.  Because of its low
economic value and its many surface exposures, very few underground
mined openings exist in granite, except in those areas where minerals
associated with the intrusive body are concentrated.  A few mined
openings in granite have been constructed for the underground storage
of liquefied petroleum products.

Figure 12 shows those areas of the United States in which intrusive
igneous rocks can be found at or near surface.  This figure does not
show those intrusive igneous rocks that occur within Zone 3 of the
Seismic Risk Map of the United States or would be indurated by a 150
meter (492 foot) rise in sea level.
OPERATING MINES

Each of the major conventional salt mines are described using infor-
mation available in the literature.  In most cases the published infor-
mation was concerned with mining or construction problems with little
regard for the geology except as it was pertinent to a problem.

Two limestone mines are also described.  These were picked to illus-
trate the extremes of underground mining conditions in limestone.  The
last description is a generalized description of hard rock metal mines
in sedimentary lithologies.

This broad overview provides a fair representation of these mining
environments, while at the same time, it indicates the lack of perti-
nent geologic information about the mines.

Retsof Mine

The International Salt Company's Retsof Mine in Livingston County,
New York, is the largest underground salt mine in the Western Hemi-
sphere.  Salt has been mined here since the completion of the first
shaft in 1885.  Salt has been produced in New York State since 1661 by
the evaporation of brine from salt springs.  In 1878, rock salt was
found in the state when a well drilled in Wyoming County by the Vacuum
Oil Company penetrated a 20 meter (70 foot) thick salt bed at a depth
of 390 meters (1,270 feet).  As a result of this discovery, salt was
soon being mined by solution methods.

After drilling an exploratory hole to prove the existence of salt, the
Retsof Mining Company began sinking a 3.7 by 5.5 meter  (12 by 18 foot)
shaft in August of 1884.  The shaft was completed in the fall of 1885
and since then, the Retsof Mining Company has produced salt by room
and pillar mining methods.

Since completion of a second 2.7 by 8.5 meter  (9 by 20 foot) shaft in
1920, a panel system of room and pillar mining has been used.  The
                                   54

panels are 152.4 by 731.5 meters  (500 by  2,400  feet)  with 20 rooms to
a panel.   Seventy percent of  the  salt is  extracted with the remaining
thirty percent left as  pillars  to support the roof.   During periods of
peak demand,  production can reach 4,540 metric  tons  (5,000 tons)  per
8 hour shift.   As of 1967, the  estimated  yearly production was 2,042,550
metric tons (2,250,000  tons).   This  is equivalent to  about 935,000 cubic
meters (33 million cubic feet)  per year.

The salt  bed  mined at the Retsof  Mine is  one of several in the Syracuse
Salt Formation of the Upper Silurian Salina Group.  It is 2.7 to 3
meters (9 to  10 feet) thick.  The mining  level  is 324 meters (1,063
feet) below the surface and 99.4  meters  (326 feet) below sea level.
Immediately above and below the mined salt are  other  less pure salt
beds that contain shale layers.   There is no mention  in the literature
of any folding or faulting in the immediate mine area.  The dip of the
bed is less than one percent  to the  south.  Figure 13 shows a geologic
column through the shaft.  The  crude rock salt  in the salt zone is
grayish-white in color  and 96 to  98  percent sodium chloride in coarse,
well-crystallized grains.  The  remaining  2 to 4 percent consists of
magnesium chloride, calcium chloride, calcium sulfate, and water.

The mine workings are dry except  for water that seeps down the shafts.
Seepage down the shafts is about  1,325 liters  (350 gallons) per hour.
Pumping 20 to 25 hours  per week,  with a  190 liter  (50 gallon) per minute
capacity pump, can remove all the water  that accumulates.  The forma-
tions immediately above and below the mined salt bed  do not produce any
water.  Exploratory drilling  has  revealed a brackish aquifer approxi-
mately 65.3 meters (280 feet) below  the mined  salt bed.  Because of
numerous intervening shale beds though, no fluid communication has been
established except through man-made  openings.

Although there is no report in  the literature of stability problems
in the Retsof Mine, roof falls  and floor  heaving often occurs in mines
with high extraction rates.

The temperature in the  mine remains  nearly constant  throughout the year
at 16°C (61°F).  The relative humidity averages 58 percent.

Examination of the Seismic Risk Map  of the United  States indicates that
possible damage from an earthquake in the Retsof Mine would range from
minor to moderate from earthquake intensities  of V to VII on the Modi-
fied Mercalli Intensity Scale of  1931.

Seneca Lake Mine

Rock  salt is also mined in New  York State by the Morton Salt Company
from  its Seneca Lake Mine in  Yates County.  The salt bed being mined
at Seneca Lake is one of several  in the  Silurian Salina Group.  The bed
is about 3.0 meters  (10 feet) thick and  approximately 610 meters (2,000
feet) below the surface.  Production at  the mine can reach 7,550 metric

tons (8,300 tons)  per day which is equivalent to about 3,400 cubic
meters (120,000 cubic feet)  of mine volume.

It has been stated that there is no stability problem at the salt mine
at Seneca Lake. The only water entering the mine workings is from
seepage,  about 19  liters (5  gallons) per minute, down the two access
shafts.

Seismicity at the  Seneca Lake Mine has not been severe during the his-
toric past.

Cayuga Salt Mine

Cargill Incorporated mines salt near Ithica, New York.  Production can
reach 3,550 metric tons (3,900 tons) per day from a salt bed in the
Silurian Salina Group.  Local thickening and thinning of the salt bed
is present at the  Cargill Salt Mine.

It is reported that there are no problems with water entering the mine
workings at the present time; however, water has in the past entered
through the shaft  when hydro-fracturing operations were underway at
nearby brine wells.

The Cargill Mine is situated near the boundary of the 1 and 2 Seismic
Risk Zones on the Seismic Risk Map of the United States, thus indicat-
ing a Modified Mercalli intensity of minor to moderate surface damage.

Fairport Harbor Mine

The Morton Salt Company produces salt by conventional mining at its
Fairport Harbor Mine located in Grand River, Lake County, Ohio.  Mining
operations began in 1959 and the company now produces over 909,000 met-
ric tons (one million tons)  per year from the mine.  This is equivalent
to approximately 410,000 cubic meters (14.5 million cubic feet) of the
mine volume.

The salt bed being mined by the Morton Salt Company is the second salt
horizon of the Silurian Salina Group.  This horizon is equivalent to
the F-l unit in the Michigan Basin.  The mining level is 585.5 meters
(1,921 feet) below the surface.  No information has been found con-
cerning mine stability or other mining problems at the Fairport Harbor
Mine, but  it is assumed that they would be about the same as problems
encountered in other mines in bedded salt deposits.

The Fairport Harbor Mine  is  situated between the 1 and 2 Seismic
Risk Zones on the Seismic Risk Map  of the United States, indicating
minor  to moderate earthquake intensities during the historic past.

Whiskey Island Mine

The International Salt Company produces over 909,000 metric tons  (one
                                  58

-------
million  tons)  per  year  from  its Whiskey Island Mine located under the
Whiskey  Island industrial district of Cleveland, Ohio.  The working
level  is 539.5 meters (1,770 feet) below the surface with a large part
of the workings extending under Lake Erie.  Rock salt at the Whiskey
Island Mine  is produced from the first salt horizon of the Silurian
Saline Group.   The first salt horizon of Ohio is equivalent to the F-2
unit of  the  Michigan Basin.

Operations at  the  Whiskey Island Mine are unique in that it is the only
salt mine in the United States that is intersected by faults.  One
of the faults  intersecting the mine has a throw of 17.4 meters (57
feet).   Special mining  procedures are followed at the Whiskey Island
Mine to  avoid  problems  created by the faulting and extensive horizontal
exploratory  drilling is done to prevent mining into water filled fault
spaces.

The Whiskey  Island Mine is located in Seismic Risk Zone 1 on the Seismic
Risk Map of  the United  States.  This corresponds to modified Mercalli
Intensities  of  V and VI, indicating minor surface damage.

Detroit  Mine

Although about  25  percent of the United States production of salt is
from the Michigan  Basin, most of- the salt mined in this basin is pro-
duced  by solution  mining.  The International Salt Company's mine near
Detroit  is the  only room and pillar salt mine in the basin.

The International  Salt  Company has mined salt from the B Unit of the
Salina Formation since  the completion of the first shaft in 1910.
The salt bed is a  comparatively flat 6.1 meter (20 foot)  thick bed that
is bordered  on  top and  bottom by limestone beds.   Figure 13 shows a
geologic  column through the  shaft.

The mining level is 313.9 meters (1,030 feet)  below the surface.   Very
little information on the size of the mine workings is available, but
the production  is  about 2,700 metric tons (3,000 tons) per day.   During
construction of the shaft,  four water-bearing intervals were penetrated
before reaching the salt.   The water flow from these intervals into the
open shaft was  estimated to be approximately 7.6 million liters (2 mil-
lion gallons) per minute.

Examination of  the Seismic Risk Map of the United States indicates that
the International  Salt  Company's Detroit Mine is in Zone 1.   Structures
in Zone  1 of the Seismic Risk Map could sustain minor damage from dis-
tant earthquakes.

Kansas Salt Mines

The Hutchinson  salt member of the Wellington Formation (Early Permian
Age)  is  conventionally mined at three sites in central Kansas.   Five

nonoperating mines are also located in this region, however two of
these are known  to be flooded, the status of two others is unknown, and
one is nonoperating but in reasonably good condition.  The nonoperating
mine located at  Lyons is owned by the Carey Salt Company and was most
recently utilized as a model facility for radioactive waste storage.

The present mining activity in Kansas is at the Carey Salt Company
mine in Hutchinson, the Independent Salt Company mine at Kanopolis, and
the American Salt Company mine at Lyons.

Carey Mine—

The Carey mine at Hutchinson excavates salt at a depth of 196.6 meters
from a 3 meter (10 foot) thick bed of high purity halite (95%).  Removal
is through a 4.6 meter (15 x 15 feet)  square shaft.  The estimated
mine volume is in excess of 1.8 million cubic meters (100 million
cubic feet).

The stability of the Carey mine is quite impressive with only occa-
sional signs of deformation being visible.  Weaker areas are routinely
supported by wood pillars; however,  these areas are not common and are
usually attributable to excessive extraction ratios.  Roof and floor
control is maintained along continuous,  parallel and nearly horizontal
shale seams which are natural plains of parting and allow very uniform
openings.  The mine is dry and aquifers above and below the mine are
well isolated by thick salt plus extensive overlying and underlying
shale units.

The Carey mine is unique in that a portion of the older workings are
utilized concurrently for the storage  of valuable documents.   A portion
of the mine excavated some 50 years ago is leased to Underground Vaults
and Storage Incorporated and is operated independently of the salt mine.
The near constant temperature (20.6°C  or 69°F)  and relative humidity
(50%) are almost ideal conditions for  the storage of documents, film,
and other similar material.  A basic requirement for this operation to
be successful is a safe, stable environment since many of the items
stored are irreplaceable.

The Carey mine is not known to intersect any faults and is located in
a tectonically stable region (Seismic  Risk Zone 1).

Independent Salt Mine—

The Independent Salt Company mine in Ellsworth County,  Kansas mines a
3 meter (10 foot) thick salt bed at  a  working depth of 263.7  meters
(865 feet).  The salt is removed through two shafts, one of which is
2.4 by 6.1 meters (8 by 20 feet)  while the other is 2.4 by 4.9 meters
(8 by 16 feet).  It is estimated that  approximately 7.1 million cubic
meters (250 million cubic  feet) of space has been excavated at the
Independent mine.
                                   61

-------
Little information is available concerning the structural and hydro-
logic conditions of the Independent  mine.   However,  they are expected
to be similar to other salt mines, relating primarily to extraction
ratios and engineering design.   Flooding potential is remote due to
the thickness of the salt and shale  sequences which separate the aqui-
fers from the mine opening.   Seismic risk  is low in the mine area, and
historically the region has been tectonically quiet.

American Salt Mine—

The American Salt Company operation, located near Lyons, Kansas, pro-
duces salt by both conventional and  solution mines.   The conventional
mine produces salt from a 2.6 meter  (8.6 foot) thick bed of high purity
salt at a depth of 302.7 meters (993 feet).  Present production is
through a 2.1 by 2.1 meter (7 by 7-foot) shaft.  The volume of mined
space is estimated to be about 2.9 million cubic meters (45 million
cubic feet).  The structural integrity of  the conventional mine is
typically very good except where the extraction has exceeded 75 percent.

Hydrologic isolation is similar to the other Kansas salt mines except
that there are many nearby boreholes.  In  one instance the mine inter-
sected an unsurveyed and abandoned borehole which fortunately was
plugged tight.  Had the plug been ineffective, serious water inflows
might have resulted.  Other old boreholes  in the Lyons area have
been known to allow water inflows which have, in time, resulted in ex-
tensive salt dissolution and surface subsidence.  In addition, the
hydraulic mining operations near the American mine would seem to offer
some low, but indeterminate risk to  the conventional mine.

No faults are indicated in the American mine and seismicity is low in
this region, rating a Zone 1 on the  Seismic Risk Map.

Hockley Mine

The United Salt Corporation mines salt from the Hockley dome in Harris
County, Texas.  The mine site is approximately 50 kilometers (30 miles)
northwest of Houston.  The Hockley salt dome was discovered in 1906 when
an exploratory hole was drilled to  investigate surface occurrences of
sulfur water and natural gas.  During the  years since this first hole
was drilled, over one hundred additional wells have been sunk while
exploring for petroleum, sulfur, and salt.  Figure 15 shows an idealized
cross section of the Hockley Dome.   Salt has been conventionally mined
at Hockley since the completion of the first shaft in 1932 at a depth
of 464.8 meters (1,525 feet).  For a time during World War II, gypsum
was mined from the cap rock overlying Hockley dome and in 1945, a small
oil field was developed.

Information concerning salt production at  the Hockley Mine was not
found in the literature.  Mine design was simply noted as room and
pillar.  The present volume and utility of mined space is unknown, but
                                   62

is assumed to be quite large based on the number of years of operation,
and the large volume economics of salt production.

Drill hole data indicates that the intrusive salt stock is oval shaped
with its long axis trending north-south.  The outside dimensions of
the dome are roughly 5,182 meters by 3,962 meters (17,000 by 13,000
feet).  The top of the salt is nearly flat ranging from 50.3 to 60.9
meters (165 to 200 feet) above sea level in the recorded drill holes.

Overlying the salt stock are Miocene and Oligocene sands and clays and
a thick cap rock formation of brecciated calcite and limestone, gypsum,
and massive anhydrite with local sandy zones.  Figure 16 shows the
stratigraphic column of the mine shaft.

The unconsolidated sand and clay deposits extend to a depth of 23.2
meters (76 feet) at the mine shaft and locally contain water.  The
upper cap rock unit is a brecciated limestone extensively interlaced
with vuggy stringers and veins of calcite.  The unit contains a bottom
layer of less than 1 meter  (30 inches) composed of gray calcitic sand.
The 9 meter (30 foot) thick limestone unit is very porous and yielded
both oil and water during construction of the shaft.  A gypsum unit
underlies the limestone and extends down 5.5 meters (18 feet) where it
grades into the thick anhydrite below.

The anhydrite unit is 270 meters  (886 feet) thick.  Between 243.8 and
274.3 meters (800 and 900 feet) in depth, there exist many thin cal-
careous sandstone bands interbedded with the anhydrite as well as
larger sandstone inclusions.  The sandstone beds are typically less
than 5 centimeters (2 inches) thick while the larger rounded inclusions
reach 10 centimeters  (4 inches) in diameter.  Near the base of the
anhydrite unit, occasional  isolated salt lenses were encountered rang-
ing up to 3 meters (10 feet) long by 1.5 meters  (5 feet) wide by 25
centimeters (10 inches) thick.

The structure of the anhydrite is generally massive with a well devel-
oped, near horizontal joint system.  Lesser jointing at approximately
45 degrees is common and occasional near-vertical joints were noted.
The joint planes are described as smooth and commonly coated with
dark pyrite.  The jointing  often  extends completely across the shaft
giving the appearance of bedding.

The water-bearing limestone cap rock unit has been intersected in drill
holes flanking the dome to  a depth of 320 meters  (1,050 feet) below sea
level, or 640 meters  (2,100 feet) from  the  surface.  The limestone cap
rock has yielded measurable quantities  of fresh water at this depth.
The relatively low contamination  of the ground water at such a depth
may indicate high recharge  and/or good  isolation from the salt stock.
It is possible that the Hockley dome is subject  to only minimal dis-
solution from ground water.

The Hockley Dome is located in a historically quiet seismic area, hav-
ing a rating of 0 on the Seismic Risk Map.   No major mining problems
are evident at the Hockley Mine.

Grande Saline

The Morton Salt Company mines salt from the Grande Saline salt dome
which is located about 105 kilometers (65 miles)  east of Dallas, Texas.
Indians were known to use salt originating  from local brine springs
prior to 1845, but the source of the salt was not discovered until
1888.  The Grande Saline Salt Company discovered the rock salt mass
and produced salt from brine wells until the late 1800's.

In 1930, the Morton Salt Company commenced  sinking a shaft for the
purpose of conventionally mining the salt.   In 1931, the original 4.4
meter (14.5 foot) diameter shaft was completed to a depth just below
the working level at 213.4 meters (700 feet) below the surface.  The
collar of the shaft is 119.5 meters (392 feet) above sea level.  Pro-
duction figures are not readily available,  but a production capacity
of 907 metric tons (1,000 tons) per day was found in the literature.
The volume of mined space is unknown, but is assumed to be quite ex-
tensive.

The Grande Saline salt dome is located in the Interior Subprovince of
the Gulf Coast Embayment, forming in the deep East Texas Syncline
structural trough.  Exploratory drilling has indicated that the dome
is shaped like a truncated cone with a nearly flat top averaging about
64.6 meters (212 fset) below the surface.  The diameter of the dome
is roughly 2,438 meters (8,000 feet) at the top.  Surface expression
of the dome is as a roughly circular depression forming a swampy, sa-
line lake.

Near surface deposits at Grande Saline are Tertiary beds composed of
sand, clay, and shale which grade into a soft sandstone.  At about 57.9
meters  (190 feet) in depth, there is a cap rock formation of cavernous
limestone which contains a large quantity of salt water.  Underlying
the  limestone and immediately above the salt there is about 1.5 meters
(5 feet) of impermeable anhydrite.  Large quantities of ground water
are  available from the sandy and limy formations overlying and lapping
the  Grande Saline salt dome.

The  Grande  Saline Dome lies along the dividing line separating 0 and 1
risk zones  on the Seismic Risk Map.  Both the low seismicity and an
apparent lack of diapiric movement indicate good stability at this
site.   Some difficulties were encountered while sinking the shaft
through the water-bearing strata.  Since completing the shaft, the
mine has been relatively free of major problems related to stability
or flooding.

Cote Blanche

Rock salt is mined from the Cote  Blanche  salt dome by Domtar Chemical
Company.   Cote Blanche Island  is  located  in the western part of  St.
Mary's  Parish,  32 kilometers (20  miles) south of New Iberia, Louisiana.
Exploration for salt on Cote Blanche began as early as 1862 after rock
salt was  discovered on Avery Island.  The Southern Salt Syndicate was
organized in the spring of  1921 to find and mine salt on Cote Blanche.
Fifty-four exploratory holes were drilled during the next year.  The
highest point of the salt was  found to be 90.8 meters (298 feet) below
the  surface and 90.5 meters (297  feet) below water level.  Because of
anticipated water problems  and difficulties with property leases, the
Southern  Salt Syndicate did not attempt to sink a shaft.  The Carey
Salt Company acquired the lease on Cote Blanche and began sinking a
shaft in  1963.   Mining of the  salt has been continuous since operations
began in  1964.

Access  to the mine is through  two shafts,  one 2.4 meter (8 foot) diam-
eter service shaft and one  4.3 meter (14 foot) diameter production
shaft to  a total depth of 427 meters (1,400 feet).  The mining level at
the  service shaft is 415.1 meters (1,362 feet) below the surface.  The
salt is mined in two benches by room and pillar methods.  The com-
pleted  rooms are 15.2 meters  (50  feet)  high and all entries and cross-
cuts in the production areas are  on 45.7-meter(150-foot) centers.

Cote Blanche Island  is the  surficial indication of the underlying salt
dome.   The island rises  to a maximum elevation of about 30.5 meters
(100 feet)  above sea level and is about 3.2 kilometers (2 miles) in
diameter.   It is surrounded by marsh except for the south edge which
opens onto  Cote Blanche  Bay.

Salt at the Cote Blanche dome is over 99 percent sodium chloride; present
as alternating  white and gray bands.   The darker bands of halite result
from small  amounts of  impurities.   Anhydrite (calcium sulphate)  is the
most common impurity found in the salt.

No cap  rock has been found at the Cote Blanche salt dome.   The top
of the  salt is  overlain by alluvial deposits of sand,  gravel,  and clay.
The  dome  is relatively smooth and no indication of severe overhangs have
been found.   A  fault with the downthrown side to the northwest is found
in the  surficial deposit on the south side of the island.   The fault
is believed to  have  formed as a result  of  dissolution of the underlying
salt.

Ground  water is found  in large amounts  in  the alluvial deposits above
the  salt  at Cote  Blanche.  Several water-bearing sands were encountered
while sinking the shafts into the salt.  One water-bearing sand was
found immediately on top of the salt and another sand,  containing ap-
proximately 30  percent water by volume,  was encountered at a depth of
143.3 meters  (470 feet).  Ground water  is  also present in some of the
                                    67

-------
formations that were pierced as the dome formed.   Flooding of the mine
might result if communication is ever established between these water-
bearing formations and the mine workings.

There has been no report of any stability or water inflow problem at
the Cote Blanche mine.  The mine is located in a  low risk seismic zone,
indicating minor damage from earthquakes during the historic past.

Avery Island

The International Salt Company produces salt from Avery Island which
is located about 161.1 kilometers (10 miles) southwest of New Iberia,
Louisiana.  Salt was produced from brine springs  as early as the late
1700's.  The first commercial development of the  salt springs was in
1812 by John C. Marsh, the owner of the island.  Production continued
for several years until competition from imported salt forced the
closing of the plant.  The beginning of the Civil War prompted the re-
opening of the salt works by John Marsh Avery, grandson of John C.
Marsh.  Rock salt was discovered on May 6, 1862 when the brine wells
were being cleaned and deepened.  Following this  discovery, salt was
produced from open pits until April 17, 1863 when Federal forces cap-
tured and destroyed the works.

In 1867 Chouteau and Price sunk the first shaft into the salt.  The
shaft was 27.4 meters (90 feet) deep and extended about 17.7 meters
(58 feet) into the salt.  Operations continued until 1870 when Mr. Price
died and Mr. Chouteau abandoned the mine.  The mining rights were leased
by the Galveston Company in 1879 and in 1880 they were transferred
to the American Salt Company.  Salt was produced from the existing shaft,
until 1885.  Because of the development of sinkholes that connected with
the 27.4 meter (90 foot) level, the shaft was deepened 21.3 meters (70
feet) and new workings were started 48.8 meters (160 feet) below the
surface.  The New Iberia Salt Company replaced the American Salt
Company in 1886.  Salt was produced from the newer working level by
mining rooms 24.4 meters (80 feet) wide and 12.2 meters (40 feet) high.
The pillars that were left to support the roof were 18.3 meters (60 feet)
in diameter.  In 1893, the New Iberia Salt Company subleased the pro-
perty to Myles and Company, of New Orleans.  Water entering the upper
level penetrated to the lower level and forced the abandonment of the
lower level in July,  1895 and the upper level in 1896.

The Avery Rock Salt Mining Company was organized in 1898 to produce
salt  from the old workings and to construct a new shaft.  After ex-
ploratory drilling, a site for a new shaft was selected beyond the
southwest limits of the old mine.  To prevent recurrence of the water
problems  that developed in the old mine, the new shaft was sunk to a
depth of  157.9 meters  (518 feet).  When the new shaft was completed in
 1899,  the International Salt Company acquired the Avery Island salt
mining  operations.
                                    68

-------
The International  Salt Company's production shaft is 6.4 by 3 meters
(21 by 10 feet) and divided into three compartments.  Surface eleva-
tion of the shaft  is 9.4 meters (31 feet) above sea level.  The
present mine level is 161.5 meters (530 feet) below the surface and
152.1 meters (499  feet) below sea level.  A second shaft for ventila-
tion was completed in 1920.

Salt is mined by conventional room and pillar methods.  The working
face is 30.5 meters (100 feet) across and 27.4 meters (90 feet) high.
Total production figures have not been released by the International
Salt Company, but  the annual production has been estimated at over one
million tons, which would be equal to approximately 413,000 cubic
meters (14.6 million cubic feet) of mine volume per year.

The International  Salt Company's Mine at Avery Island is in a typical
coastal salt dome.  In plan view, the dome is nearly oval in shape and
about 2.4 kilometers (1 1/2 miles) in diameter.  Maximum elevation of
the island is 46.3 meters (152 feet).  The island is surrounded by low
lying marshland.   In some areas, the top of the salt is within 4.9
meters (16 feet) of the surface.  The salt stock is fairly flat on top
and there is little indication of major cap rock development.   No cap
rock was found when the first shaft was sunk in 1867.  The salt that is
mined at Avery Island is white to light gray halite, 99 percent sodium
chloride.  It is dense, opaque, microcrystalline, and flow banded.  The
salt contains inclusions of red sandstone and a small amount of other
evaporites.

Oil and gas has been produced from the flanks of the dome.   The oil ac-
cumulated in stratigraphic traps formed by the rupturing of the lower
formations as the  dome formed.  Some of these formations contain con-
siderable amounts  of water and flooding of the mine might occur if the
edge of the dome is penetrated by mining or drilling.  The top of the
salt dome is overlain by water-saturated sand, gravel,  and clay de-
posits.  The water table at the site of the old mine shaft was 7.3 me-
ters (24 feet) below the surface and the top of the salt was 16.5 me-
ters (54 feet) deep.  When salt was mined on the 27.4 meter (90 foot)
level, open fractures were developed between the mine and the overlying
water table.  As a result of water seeping down these fractures, sink
holes were developed as early as 1883, and eventually prevented oper-
ations out of the  original mine shaft.

The Avery Island dome is in seismic risk zone 1, indicating low inten-
sity earthquakes causing only minor surface damage.

Weeks Island

The Morton Salt Company mines rock salt by the room and pillar method
at the Weeks Island salt dome.  Weeks Island is located 24.1 kilometers
(15 miles) south of New Iberia,  Louisiana.

After the discovery of salt on Avery Island in 1862, several unsuccessful
                                   69

-------
wells were dug on Weeks Island in the search for salt.  Salt was not
found on Weeks Island,  however,  until July of 1897,  when Mr. F. F. Myles
had 14 exploratory holes drilled.  The Myles Salt Company was formed
in 1898 and 14 more exploratory holes were drilled to determine the
best area for the mining of the salt.  Construction of the first shaft
was started in July of  1898.   Production did not begin until March of
1902 because of water problems encountered while constructing the shaft.
The Myles Salt Company  merged with the Morton Salt Company in 1948.

The original shaft was  3.5 meters (10 feet) in diameter and 196.6
meters (645 feet) deep.  The floor level of the mine was 163.1 meters
(535 feet) below sea level.  This level, which is now abandoned, had
rooms 18.3 to 27.4 meters (60 to 90 feet) high.  The present mining
level is 231 meters (758 feet below the surface and 208.5 meters  (684
feet) below sea level.   The salt is mined by multiple bench, room and
pillar methods.  Depending on which bench is being mined, the rooms
vary in height from 7.6 to 27.4 meters (25 to 90 feet).

Weeks Island is the top of a coastal salt dome.  It is about 3.2 kilo-
meters (2 miles) in diameter and the maximum elevation is 41.1 meters
(135 feet) above sea level.  Little indication of cap rock development
has been found at Weeks Island.   The salt which rises to within 26.8
meters (88 feet) of the surface is overlain by beds of sand, gravel,
and clay.

The salt is over 99 percent halite.  In some areas, bands of very pure
white salt alternate with darker, less pure salt bands.  The darker
colored bands result from the presence of impurities of 2 to 4 percent
anhydrite.

As in the case of most  salt domes, water could present a serious
problem at the Weeks Island Mine.  Large amounts of water are present
in the surficial sand and gravel beds and in the subsurface beds pene-
trated by the dome.  Flooding of the mine working could result if the
edge of the dome was ever breached.

Weeks Island, like the others in the Five Islands group is in a low
intensity seismic risk zone.

Jefferson Island

The Diamond Crystal Salt Company's Jefferson Island mine is located
about 14.4 kilometers  (9 miles) west of New Iberia, Louisiana.

In reality, Jefferson Island is not truly an island, since it is not
surrounded by water.  The name is derived from its resemblance to the
other domes in the Five Islands group.  The maximum elevation of Jeffer-
son Island is 22.9 meters  (75 feet) above the surrounding plains and
the area of the Island is about 1,212 square kilometers  (300 acres).

The first attempt at mining the salt at Jefferson Island was in 1919
                                   70

-------
when the Jefferson Island Mining Company started sinking a  shaft.   The
shaft was  lost  at  the  top of  the salt when flooding occurred.   In  1920,
a new shaft was started but continuous production did not begin until
1922 when  water leaks  around  the shaft were sealed off.  Production in
1973 was 1,497,870 metric tons  (1,650,000 tons) which is equivalent
to about 680,000 cubic meters  (24 million cubic feet).  The original
shaft entered the  salt 12.2 meters  (40 feet) below sea level and 30.5
meters  (100 feet)  below the surface of the ground.  The diameter of
the shaft  was 7.6  meters (25  feet) and its depth was 274.3 meters
(900 feet).  The working level was 243.8 meters (800 feet) below the
surface.

Jefferson  Island is a  typical coastal salt dome.  Cap rock has been
found in only a few exploratory holes and consists of 45.7 to 60 centi-
meters  (18 to 24 inches) of gray limestone.  The majority of the over-
lying material  is  sand and gravel with a few scattered lenses of clay.
Salt from  domes is very pure, usually over 99 percent sodium chloride.
The salt at Jefferson  Island  tends to be somewhat lighter in color  and
firmer  than salt from  the rest of the Five Islands group.

Possible water  problems might be encountered at the Jefferson Island
salt mine  because  the  top of the dome is overlain by water-bearing
sand and gravel deposits and the north-west edge of the dome is under
Lake Peigneur.

Jefferson  Island is located in zone 1 on the Seismic Risk Map of the
United  States.

Belle Isle

Cargill Incorporated mines salt from the Belle Isle salt dome,  which is
located 30.6 kilometers (19 miles)  southeast of Franklin,  Louisiana.
After the  discovery of salt on Avery and Jefferson Islands,  exploration
for salt was started on the other domes in the Five Islands  group.   Ex-
ploratory  drilling on Belle Isle was started in November,  1896  by
Captain A. F. Lucas.  The first drill hole encountered salt  at  a depth
of 113.7 meters  (373 feet)  in December of 1896.  After drilling fourteen
exploratory holes  during 1896 and 1898,  the Gulf Company began  sinking
a mine shaft in August, 1889.   The shaft was completed to a  depth of
118.8 meters (390  feet) and a heading was driven eastward for 103.6
meters  (340 feet).  At this point,  water poured in and within two hours
completely flooded  the workings.

A second shaft was started 0.4 kilometers (1/4 mile)  southwest  of the
original workings, but it was abandoned at a depth of about  60.9 meters
(200 feet) because of problems with quicksand and soft clay. After the
loss of the second shaft,  an attempt was made to produce salt by solu-
tion mining.  This process  was abandoned because of impurities  in the
salt and the possibility of caving  of the unconsolidated overburden.
No salt was produced again from Belle Isle until 1963,  when  Cargill
                                   71

-------
Incorporated began mining salt from a depth of about 365.7 meters
(1,200 feet).

Belle Isle is roughly triangular in shape and rises to a maximum eleva-
tion of 24.4 meters (80 feet)  above the surrounding marshes and bayous.
The top of the salt at the highest point is 41.8 meters (137 feet)
below the surface and cap rock is 33.5 meters (110 feet) below the
surface.  Salt near the surface at Belle Isle is less pure (approxi-
mately 93-96% sodium chloride) than the salt from the others of the
Five Island group,  (98-99 percent sodium chloride), but the purity
increases with depth.

The cap rock is better developed at Belle Isle than all the other domes
in the Five Islands group.  Some of the holes drilled into the Island
penetrate over 152 meters (500 feet) of gypsum, anhydrite, and sulfur
immediately above the salt.  Surficial deposits, consisting of inter-
bedded sand, gravel, and clay, vary considerably in thickness because
of uneven dissolution of the top of the salt stock.  As is common with
most salt domes, large amounts of water are present in the formations
surrounding the Belle Isle salt dome.

Since Cargill Incorporated began mining operations at Belle Isle, the
most serious problem that has been reported occurred on March 3, 1973
when partial flooding of the mine workings resulted from water inflow
around the No. 2 Shaft.  Subsidence of the surface facilities near
the collar of the shaft occurred due to the great volume of material
removed from around the shaft by the flowing water.  Mining opera-
tions have been suspended at Belle Isle until the No. 2 Shaft can be
rehabilitated.

Belle Isle is also located in a low risk seismic area.

Limestone Mines

In the Kansas City, Missouri area, favorable geological conditions
associated with the Bethany Falls Limestone Member of the Kansas City
group have led to the development of extensive underground space that
is suitable for storage.  There is approximately 11 million square
meters  (120 million square feet) of underground space in an area within
a radius of 40 kilometers  (25 miles) of downtown Kansas City.  Of this
amount of space, 1.4 million square meters (15 million square feet) is
currently being used and another 2.8 million square meters  (30 million
square feet) is suitable and available for use.  Currently, one seventh
of Kansas City's warehouse space is located underground in converted
limestone mines.  Most of  this space is developed  in the Bethany Falls
limestone.

Mining of the Bethany Falls limestone began in  the late 1800's to
supply  construction material for the industrial development of the
Kansas  City area.  The Bethany Falls was initially quarried along the
outcrop  of  the limestone  in the larger stream valleys.  When the
                                   72

-------
thickness of the overburden became too great to be economically
stripped from the top of the limestone, horizontal entrances were con-
structed and underground mining by room and pillar methods was started.

Extensive mining of the Bethany Falls and the use of the mined out
space for storage resulted from a combination of several geological
factors.  Rock has been produced from the Pennsylvanian Bethany Falls
Limestone Member because it is one of the few formations in the area
that contains limestone which will meet the requirements for highway
and other types of construction.  The limestone bed is almost hori-
zontal and is present below most of Kansas City and the surrounding
area.  The dip of the bed is about 2 to 4 meters per kilometer (10 to
20 feet per mile) to the north.

The Bethany Falls is light to dark gray, fine-grained to crystalline,
mottled limestone with massive bedding at the top and thin bedding
near the base.  Joints in the Bethany Falls are tightly closed, nearly
vertical, and discontinuous.  The joints trend N 60°E to N 70°E and the
joint spacing averages 16.5 meters (54 feet).  The joint spacing de-
creases as the outcrop is approached.  A well defined bedding plane,
1.2 to 1.8 meters (5 to 6 feet) below the top of the unit,  eases the
construction of a smooth stable roof for the rooms.   In the metropolitan
Kansas City area an overlying strata thickness of over 61 meters (200
feet) prevents the weakening of the roof by weathering processes.

Ground water is not a serious problem in the mined openings of the
Bethany Falls limestone.  Impermeable shale beds above and below the
Bethany Falls prevent water movement into the limestone.  The only
ground water entering the workings are from small seeps near the out-
crops and from seepage around rock bolts that penetrate the overlying
strata.

The Bethany Falls Limestone in the Kansas City,  Missouri area is cur-
rently being mined by underground methods at about a dozen mines.   New
underground space is being created at a rate of about 485,000 square
meters (120 acres) per year.

An example of a limestone mine that would be less desirable for storage
purposes, because of geological/hydrological factors, is the Kimballton
Limestone Mine of Standard Lime and Cement Company in Giles County,
Virginia.

The Standard Lime and Cement Company produces over 1,545 metric tons
(1,700 tons) per day of high purity limestone from the Ordovician Five
Oaks Member of the Cliffield Formation.   The high-calcium limestone is
burned for conversion to lime.

There are a combination of factors why the Kimballton Limestone Mine
would be less desirable than other mines for underground storage and
these are:
                                   73

-------
     1.    Regional  tectonics have deformed  the Five Oaks  limestone bed
          in the Kimballton area.  The bed  is gently undulated and dips
          about 15  degrees to  the southeast.

     2.    Numerous  interload tension  fractures were formed by the warp-
          ing of the bed.  Many of the fractures have  been healed by
          calcite,  but  some of the fractures are open  and lined or
          filled with red clay or silt.

     3.    Two faults have been excavated  during mining operations at
          the Kimballton Mine.  The total vertical displacement along
          the faults is about  15.2 meters (50 feet).   In  the area of
          the faults the level of the floor had to be  lowered in order
          to continue operations.

     4.    Large amounts of water can  enter  the mine along old water
          channels  shortly after heavy rains.  The existence of a water
          filled channel that  connects with the mine has  forced the
          abandonment of the lower working  of the mine.  The abandoned
          workings  are  now used as a  sump.  Water is almost continu-
          ously pumped  from the sump  to  the surface at a  rate of 13,200
          liters  (3,500 gallons) per  minute to prevent flooding of the
          workings.

"Hard Rock" Mines

There are 30 to  35  mines throughout the  continental United States
presently active in recovering metallic  and industrial minerals by
room and pillar methods.  The  minerals mined  consist of ores for anti-
mony, barite, copper, fluorspar, iron, lead-zinc, silica, and talc.
The most numerous  of the hard  rock mines are  those  from which lead-
zinc ores are recovered.

Most of the detailed information concerning these mines is held, either
in confidential  files or as unpublished  information, by the mining
companies.  However,  some general characteristics of room and pillar
hard rock mines  and the range  of conditions which may  occur can be
described.

Mineral occurrences suitable  for room and pillar mining are bedded de-
posits often in  or associated  with  limestone  or dolomite horizons of
sedimentary basin  structures.  Metallic  element mineralization occurs
as irregular bands, lenses,  and  fine  disseminations  of ore minerals in
limestone or shaly limestone  horizons.   Structure of  these deposits
vary from very complex  to  simple.   Faulting is  commonly present and
developed to any degree,  from occasional gravity  faults with minor
displacement, to major  shear  zone  intersectors where ore has been moved
great distances.

Hydraulic problems vary from minor  to extreme.  Mines  in the Picher
                                   74

-------
field of Oklahoma and Kansas incorporate vast areas of room and  pillar
excavation, now mined out, which have been allowed to flood and  now  are
filled with water.  Quite often the structural features such as  faults,
joints, and bedding plane permeability which allow ore bearing solu-
tions to form the deposit remain open and thus allow ground water  to
invade a mine.

An example of a lead-zinc mine active in 1964 is the Young mine  of
Jefferson County, Tennessee.  The Young mine ore body is a domed sloped
structure varying from 183 to 246 meters (600 to 808 feet) below the
surface and roughly 1.5 kilometers (one mile) in diameter.  The  ore
zone varies from 21 to 30.5 meters (7 to 100 feet) thick and consists
of zinc sulfide-sphalerite.  Between 1955 and 1964 some 4,535,900
metric tons (5,000,000 tons) of ore was mined.  The mining method is
trackless room and pillar development of the ore body with systematic
placement of chutes from the ore body to haulage drifts developed be-
low the ore zone.  Transport on the haulage level is by rail.  All
leakage and drilling water, about 757 liters/minute (200 gallons/min)
of which probably 379 liters/minute (100 gallons/min) is leakage, runs
to a central sump and is pumped to the surface.

As the mine appears in the 1964 report, it is divided into four separate
sections with one or two interconnected passages, thus allowing com-
partmentalization.

It must be pointed out that when considering metal mines having a rela-
tively high product value, a change in the price of metal may alter
the configuration of the future development of a mine allowing the ex-
traction of lower grade ores in times of high metal prices.  Mines are
frequently reopened several times during their existence,  especially
those whose limits are determined by economic cut off ore grades.
EVALUATION OF GEOLOGIC ENVIRONMENTS

The suitability potential of several geologic environments can be aug-
mented by illustrating those areas of the United States which presently
have mined storage of liquid petroleum products.  Figure 17 shows the
location of LP-Gas storage caverns in various rock mediums.  All were
mined using room and pillar methods in lithologies which were found to
be essentially impervious and well isolated.   An important requirement
at most of these sites was that the product be stored under pressure.
The success of these caverns, which have an aggregate volume of more
than 1,700,000 cubic meters (60,000,000 cubic feet),  demonstrates
that secure containment is possible in carefully selected underground
environments.

The investigations of salt and other underground environments have
highlighted many of the characteristics which can be  either beneficial
or detrimental to the underground storage of hazardous chemical wastes.

-------
Following is a summary of these characteristic features, with a  sub-
jective analysis of their significance to underground waste storage.

Salt

Salt deposits are widely distributed and commonly mined using room and
pillar methods.  In general, salt environments are impervious to water
and well isolated from aquifers.  Salt is a competent structural mate-
rial, not often subjected to severe seismicity or faulting.  Bedded
salt deposits are less subject to severe water problems than salt domes.
Natural salt deposits are very pure allowing excellent reactivity anal-
ysis.  Depths, thicknesses, and inclination are all favorable for stor-
age.  Salt is self-healing and behaves plastically, which acts to reduce
mining hazards and allows easy reexcavation and maintenance of mined
openings.  Salt is not subject to alteration, but is readily soluble in
water.  Surface relief and access to bedded salt environments are good.
Certain salt environments should be very good for hazardous waste
storage.

Gypsum

Gypsum deposits are widely distributed and sometimes mined by room and
pillar methods.  Physical characteristics are good, but thin bedding and
near surface occurrences will limit the utility of gypsum environments
by reasons of isolation, structure, maintenance, etc.  Gypsum is soluble
in acids and ammonium salt solutions.   If carefully chosen, certain
gypsum deposits should be found suitable for hazardous waste storage.

Potash

Potash is similar to salt with these exceptions:  limited occurrence,
higher economic value, and greater extraction ratios.  Potash,  like
salt, has a very good potential for storage.

Shale

Shale environments are widely distributed.   Shales are essentially im-
pervious and are effectively isolated  from water when very thick.
Depth and inclination are often satisfactory.   Ion exchange capacity is
a potentially beneficial characteristic of  shales.  Shales have
limited plasticity under stress.   Structural problems are often re-
lated to thin bedding.  Shales are not commonly mined.   Montmorillonite
rich shales absorb fluids and expand,  thus  limiting integrity and sta-
bility.  Shales have limited potential for  mined waste storage.

Limestone

Limestones are widely distributed and  commonly mined using room and
pillar methods.  Limestone environments in  wet climates are often wet
due to solubility.   Plastic behavior is minimal;  however,  competence
and stability are good when bedding is massive and structure is undis-
                                   77

-------
turbed by faulting, fracturing,  etc.   Isolation from water is most
likely in dry climates.   Calcium carbonate in limestones is reactive
with acids, and strong ammonium salts such as ammonium chloride, ni-
trate and sulfate.   Some limestone environments may be found suitable
for hazardous waste storage,  particularly in arid regions.

Granite

Granite and related intrusives occur  in areas where the other lithol-
ogies do not occur.  Strength and impermeability, when not fractured,
are excellent.  Room and pillar mining is possible but is used only for
special purpose storage.  Seismic risk is commonly greater in granite
areas, as are fracturing and  faulting.  Erosion and alteration act
slowly.  Surface relief and access are locally limited.  In certain
areas granite environments should be  found suitable for mined storage
of hazardous wastes.

Preliminary Decision Model -  Waste Storage Mines

To facilitate the evaluation  of these, or other, lithologic environ-
ments and mined openings, a preliminary decision model has been devel-
oped and is presented in Figure 18.  Using this model it is possible
to screen any mined environment for preliminary suitability.  By sub-
jecting all potential underground storage sites to this screening tech-
nique as the information becomes available, it will be possible to
arrive at a listing of the most promising sites.  These sites can be
further evaluated and subjectively compared using the method presented
below.

Value Judgment Rating

The results of the geologic investigation indicate that certain lith-
ologic environments are more  suitable for hazardous waste storage with
respect to the established criteria.   In order to relatively compare
and rank each lithosphere, a  value judgment rating matrix was developed,
and is presented in Table 2.

On the upper half of the two-part matrix the fundamental suitability
criteria and the seven lithologic environments are listed.  In addi-
tion, there is an "ideal" heading which represents a perfect underground
environment for hazardous waste storage.  This "ideal" environment would
fulfill all of the designated criteria 100 percent when mined.

Beneath all of the studied environments, there are numbers assigned to
represent their potential for fulfilling each of the listed criteria.
These are shown as a percent  of the "ideal".  For instance, bedded
salt is listed as having the  potential to be 90 percent of the "ideal"
(dry and impervious) condition when mined, while granite has only 40
percent potential.

The percent values listed would normally be conservative if only
                                   78

considering a single, well-chosen site within a given lithologic  en-
vironment because the environments shown represent a composite of all
the occurrences, and thus include both the best and worst natural con-
ditions .

The lower matrix was developed to subjectively rank the lithologies
as compared to the "ideal".  In this matrix each of the criterion have
been assigned a weighted value to indicate its relative importance to
a complete suitability assessment.  The percent ideal values listed
under each lithologic environment in the upper matrix, times the  "weigh-
ted value" assigned to each criterion gives the "percent suitability"
values shown in the lower matrix.

For instance, bedded salt with a 90 percent of "ideal" in the upper
matrix has a 16.2 "percent suitability" in the lower matrix, which is
90 percent of the weighted value (18) assigned to the criterion,  "Dry
and Impervious."

By totaling all of the "percent suitability" values listed under  each
lithosphere, a total "suitability value" was obtained for each environ-
ment and is shown as a percent of the "ideal" environment.

On the basis of this evaluation,  bedded salt is accorded the highest
percent suitability (89.3 percent),  closely followed by potash,  (88.7
percent).  Domal salt,  (77.2 percent),  and gypsum (74.0 percent)  are
ranked third and fourth followed by granite (63.8 percent),  shale "2"
(55.2 percent), limestone (54.7 percent)  and shale "1" (48.5 percent).
These values indicate the potential for each of these lithospheres to
meet the suitability criteria,  if mined for this purpose.   They do
not represent past or present mining operations,  methods,  or conditions.

All of the assigned values were subjectively selected to reflect  the
relative geologic suitability of  each lithology as an environmentally
acceptable medium for storing hazardous wastes.   Other researchers may
evaluate the geological suitability differently,  however,  it is  un-
likely that the relative rankings will  change significantly.  By  the
addition of economic and other parameters which are not  within the
scope of this study,  this rating  matrix could be developed into  an even
better decision making tool.

                               SECTION 6

                        WASTE CHARACTERIZATION
The characterization of the wastes was primarily concerned with de-
termining the environmental acceptability of the wastes for under-
ground storage according to their hazards.  This determination was ap-
proached from three main viewpoints:

     1.   An investigation of the physical,  chemical,  and hazardous
          properties of the wastes to assess their acceptability for
          underground storage before  and after treatment.

     2.   The control of possible environmental contamination through
          proper treatment and containerization.

     3.   An investigation of possible environmental degradation which
          may occur after storage from the chemical interaction of the
          wastes with each other and  with the geological formations or
          from waste migration.

From a review of existing literature, it quickly became evident that
previous studies have been primarily  concerned with identifying and
analyzing the most hazardous constituents in waste streams rather than
a total waste stream analysis.  This  type of analysis has been called
the "pure-form" approach and assumes  the properties of a total waste-
stream to be identical to those of its most hazardous constituent.  Al-
though the most realistic characterization of wastes will require a to-
tal waste-stream analysis, it was necessary to use the "pure-form"
approach due to the lack of available information on total waste
streams.  However, the methodology for analysis that was developed can
be applied equally well to either "pure-form" wastes or waste-streams.
As additional waste-stream data is obtained, new candidates for storage
in underground mines can be realistically screened using the developed
methods.

The wastes considered as candidates for underground storage were non-
radioactive industrial wastes presenting special problems in treatment
or handling.  A literature review revealed that such wastes had been
identified in a previous study.  This study analyzed over 500 hazardous
                                   82

-------
 industrial wastes  and classified  them by the following disposal
 methods:

      1.    Municipal
      2.    Industrial
      3.    National Disposal  Sites  (NDS)

 Since the  115 wastes  requiring NDS disposal  were  those presenting  spe-
 cial  problems,  they were  considered as the candidate wastes  for storage
 in  a  mined facility.

 The environmental  acceptability of a  hazardous waste underground de-
 pends upon the  level  of hazard it presents prior  to storage.  A waste
 must  be evaluated  with respect to potential  effects on the biosphere
 resulting  from  its handling, treatment,  storage,  or possible migration.
 If  it was  found that  a waste was too  hazardous to the  environment  in
 its pure form,  then its hazards could, in most cases,  be reduced
 through treatment.  The treatment procedures, as presented in this
 report, are theoretical in nature.  Since an investigation of the en-
 gineering  design required to carry out these procedures was not  within
 the scope  of this  study,  it is recommended that this type of work be
 done  to confirm the practicality of the methods presented.

 It  was assumed,  for the purposes of this study, that each waste would
 be  containerized for  storage.  This assumption was based upon many fac-
 tors.  From an  environmental standpoint, the containerization of the
 wastes would provide  maximum safety during handling and storage while
 minimizing the  potential for contain nation of the biosphere through mi-
 gration.   In addition, if it became feasible to recycle a waste or an
 environmental calamity was eminent, containerization would allow a waste
 to  be retrieved from  storage without danger.   For these reasons, it was
 concluded  that  hazardous wastes should be stored in mines according to
 the Bureau of Mines safety requirement 30 CFR, Chapter 1, part 57,
 16-4  which reads as follows:  "Mandatory - Hazardous materials shall
 be  stored  in containers of a type approved for such use by recognized
 agencies;  such  containers will be labeled appropriately."  It is recom-
 mended that  research be undertaken to determine the type of container
 or  encapsulation which would meet the requirements of underground stor-
 age.

 In  order to  further analyze potential hazards to the environment after
 storage, it was assumed that the containers would be ruptured by some
 force allowing  the wastes to contact  the mine environment.   This type
 of  "worst  case" philosophy was continued throughout the investigation
whenever an  assumption as to conditions was to be made.  It should  be
 remembered,  however,  that with proper treatment and containerization,
 the probability of container rupture  or waste migration is very slight.

As  a  final step in characterizing the wastes, the magnitude of the
waste problem was assessed by compiling current volumes of the candidate
wastes from  available literature and  then projecting those volumes  to
                                   83

-------
the years 1975,  1980,  1985.  This  information was  coupled with the
earlier results  on waste acceptability to  determine the percentage of
problem solution offered by  the  concept.

The method of waste characterization developed consists of the follow-
ing steps:

     1.   Review the existing  literature and  obtain a list of hazardous
          industrial wastes  considered as  candidates for regional treat-
          ment and ultimate  deposition underground in mined openings.

     2.   Compile and present  the  physical and hazardous properties for
          the wastes of concern.

     3.   Define and establish the criteria for "ideal" waste form for
          underground storage.

     4.   Develop a Hazard Index rating of the wastes to indicate their
          acceptability as candidates for  underground storage without
          pretreatment.

     5.   Screen and divide  the  wastes according to their Hazard Index
          into those which require:

          A.  No pretreatment
          B.   Optional pretreatment
          C.  Mandatory pretreatment

     6.   Compile and present  the  best waste  treatment procedures avail-
          able for rendering the wastes to their most ideal form for
          underground storage.

     7.   Further screen and divide the wastes into those which:

          A.  Are acceptable  for  underground storage without pre-
               treatment .
          B.  Must be treated and whose  treatment products are toxic,
              but acceptable  for  underground storage.
          C.  Must be treated and whose  treatment products are essen-
               tially nontoxic but acceptable for underground storage.
          D.  Must be treated and whose  treatment requires further
               study.
          E.   Are unacceptable  for underground storage in any form.

     8.   Define and explain any potential reactions that could occur
          between the stored wastes after  they are in place in a mine.

     9.   Define and explain any potential reactions that could occur
          between the stored wastes and the receiving geological for-
          mations .
                                   84

-------
    10.   Assess  the potential for migration of  the wastes.

    11.   Compile projected volumes of  the wastes  that  can be  antici-
          pated for the years 1975, 1980, and 1985.

A schematic diagram is presented in Figure 19 showing the methodology
used for characterizing the wastes.

The following are examples of the waste characterization process util-
izing Figure 19.  The decisions resulting in the classification of the
wastes in Tables  7 through 11, as discussed later  in this section, are
depicted for a representative waste from each Table.  The examples also
indicate whether  storage restrictions are necessary due to chemical
interaction or if a waste occurs in negligible volume.  These  examples
are meant as a guide in the use of the diagram.
CADMIUM

1.   Table 3 lists Cadmium as a candidate waste.

2.   Appendix B-l lists the physical, chemical, and hazardous proper-
     ties of Cadmium.

3.   Appendix B-2 rates Cadmium waste with a Hazard Index of 2.

4.   This Hazard Index places Cadmium on Table 4, Hazard Index = 0-5
     Containerization only.

5.   Since no treatment is necessary, Cadmium was placed on Table 7, as
     acceptable for underground storage in containers without treatment.

6.   Due to its acceptability, Cadmium was analyzed for chemical inter-
     action with other wastes and with selected lithologies and found
     to be storable with any waste in any lithology.

7.   The volume of Cadmium waste was then analyzed and found to be
     sufficient to warrant regional treatment.
ALDRIN

1.   Table 3 lists Aldrin as a candidate waste.

2.   Appendix B-l lists the physical,  chemical,  and hazardous properties
     of Aldrin.

3.   Appendix B-2 rates Aldrin waste with a Hazard Index of 9.

4.   This Hazard Index places Aldrin on Table 5, Hazard Index = 6-9
     Optional Treatment.

5.   The next decision in the screening process is whether  the  hazards
     presented by Aldrin warrant treatment.  Since Aldrin is relatively
     safe at ambient conditions and its treatment would be  costly,  it
     was assumed that the risks of its untreated storage did not war-
     rant treatment.  Therefore, Aldrin was placed on Table 7 as ac-
     ceptable for underground storage in containers without treatment.

6.   Due to its acceptability, Aldrin was analyzed for chemical inter-
     action with other wastes and with selected lithologies and found
     to be storable with any waste in any lithology.

7.   The volume of Aldrin waste was analyzed and found to be sufficient
     to warrant regional treatment.
AMMONIUM CHROMATE

1.   Table 3 lists Ammonium Chrornate as a candidate waste.

2.   Appendix B-l lists the physical, chemical, and hazardous proper-
     ties of Ammonium Chromate.

3.   Appendix B-2 rates Ammonium Chromate waste with a Hazard Index
     of 21.

4.   This Hazard Index places Ammonium Chromate on Table 6, Hazard
     Index = 10-25 Mandatory treatment.

5.   Since treatment is mandatory, the remaining steps classify the
     treatment products of Ammonium Chromate.   It was found that treat-
     ment was available and that the products  of the first level of
     treatment were toxic with a Hazard Index  of greater than ten.  This
     meant that further treatment was mandatory.  The products of the
     second level of treatment were also toxic but had a Hazard Index of
     4 and therefore required no further treatment except volume reduc-
     tion by filtration.  The final product, Chromium Hydroxide and
     water, was then placed on Table 8,  as acceptable for underground
     storage in containers after treatment.

6.   Due to its acceptability,  this treatment  product was analyzed for
     chemical interaction with other wastes and with selected lithol-
     ogies and found to be storable under restrictive conditions due to
     hazardous reactions with some other wastes.

7.   The volume of Ammonium Chromate was then  analyzed and found to be
     sufficient to warrant regional treatment.

ACROLEIN

The analysis of Acrolein is similar to that of Ammonium Chromate.  Due
to its Hazard Index of 22,  the treatment of Acrolein is mandatory.  How-
ever, the treatment products of Acrolein are Carbon Dioxide and water
which are nontoxic.  Therefore, Acrolein was placed on Table 9 as hav-
ing nontoxic treatment products.  The remaining volume screening in-
dicates that the waste volume of Acrolein is negligible and should be
treated at its point of origin.
GOLD FULMINATE

Since information concerning Gold Fulminate is classified, its only
known properties were its explosive and flammable hazards.  These pro-
perties classified its treatment as mandatory.  However, since no pro-
cedure was available, it was placed in Table 10 as requiring further
study.  The volume screening indicated that a negligible amount of Gold
Fulminate waste could be expected and should be handled at its point of
origin.
MERCURY

The process for Mercury is similar to the previous examples.  Due to
its Hazard Index of 10, the treatment of Mercury is mandatory.  However,
since Mercury is an element, there is no treatment for Mercury and
little chance exists of one ever being developed.  Therefore, Mercury
was placed on Table 11 as being not recommended for storage in any form.
Due to its unacceptability the only further screening performed was
that of volume.  It was found that Mercury would occur in volumes suf-
ficient to warrant regional treatment, but its use in industry is de-
clining.  (Although Mercury wastes are not acceptable underground using
the safety criteria of this study, it is possible that other storage
alternatives will hold even greater environmental risk.)

The following discussions are presented to explain each characteriza-
tion step in detail.
STEP 1 - CANDIDATE WASTES

Many wastes which occur from industrial processes present severe hazards
to the environment.  The properties of these wastes are such that nor-
mal industrial treatment may not render them safe for conventional dis-
posal.  A list of hazardous wastes presenting special problems was com-
piled from a previous study.  Subsequent review of the methodology used
in obtaining this list was found to be consistent with the objectives
of this study.  Therefore, this list of 115 candidate wastes was util-
ized as the data base for waste characterization.  In the interest of
                                   90

-------
consistency,  the identification numbers previously assigned  to  the
hazardous wastes were maintained throughout  this  study.

The investigators of this study are basically in  agreement with the
concept of national or regional treatment facilities as suggested  by
previous contractors.  If such a treatment center were located  in  con-
junction with a mine storage facility, then  the hazardous wastes gen-
erated in a region could be handled at a centralized location.   It is
believed that this concept would greatly reduce the dangers  to  the en-
vironment presented by hazardous wastes.

The list of candidate wastes for underground storage is presented  in
Table 3.  This list may require additions or deletions as subsequent
information on waste-streams is generated.
STEP 2 - CANDIDATE WASTE PROPERTIES

Based on the pure-form approach, the physical, chemical, and hazardous
properties of each candidate waste were compiled.  This information,
along with pertinent results of the characterization of each waste, is
presented in Appendix B-l.  The information in Appendix B-l is meant
to serve as a basis for rating the acceptability of each waste for
underground storage.  Although the pure-form approach provides more
information than the waste-stream approach, significant voids in this
data do exist.  Examples of the types of information lacking are:
melting points, boiling points, flammable and explosive limits, sub-
limation temperatures, solubilities, densities, handling precautions,
toxicology, and, in some cases, chemical formulas.  Since information
concerning the properties of the hazardous constituents in waste streams
would be essential to the efficient operation of a waste facility, fur-
ther research in these areas is recommended.  If, at some time in the
future, the recommended information on waste streams per se is gen-
erated, the pure-form approach should be replaced by the waste-stream
approach.  This would necessitate the revision of some of the infor-
mation contained in this section.  However, the developed methodology
of waste characterization would remain unchanged.
STEP 3 - IDEAL WASTE CRITERIA

In considering the factors controlling the storage of hazardous wastes
in mined openings, the elimination of environmental hazards was of
primary concern.   To achieve this goal,  a method of evaluating the ac-
ceptability of each waste was required.   The methodology utilized was
to define and establish criteria for an "ideal" waste form for under-
ground storage and to compare each waste to the ideal.   The criteria
established for an "ideal" waste form are as follows:

     1.   Nonflammable.
     2.   Nonexplosive.
                                   91

-------
     3.    Nonvolatile (will not evolve flammable,  explosive,  or toxic
          gases when exposed to air,  water,  or heat).
     4.    Insoluble in water.
     5.    Nonreactive with other stored wastes or  with the receiving
          geological formation(s).
     6.    In a form which requires  the least amount of available mine
          space for storage.
     7.    Cohesive (will not create a dust),
     8.    Containerized.

These criteria apply strictly to a  theoretical waste in its most accept-
able form for underground storage.

The candidate wastes were evaluated on how closely they approached the
ideal.  It should be stressed that  a particular waste need not meet all
of the above criteria to be acceptable for underground storage.  These
criteria represent the greatest degree of protection to the environment.
Each waste form presents its own particular degree of hazard and each
hazard presents its own degree of acceptability.  The correlation of
these factors determines whether or not a waste is acceptable.  The
method used to evaluate the relationship of hazards versus acceptability
is explained in Step 4.
STEP 4 - RATING OF HAZARDS

To represent the degree of hazard of each waste a numerical rating
system was developed.  The hazards associated with the wastes of concern
were divided into six categories:

     1.   Flammable.
     2.   Explosive.
     3.   Evolve gases in air or water.
     4.   Evolve gases with heat.
     5.   Soluble in water.
     6.   Toxic.

These hazards represent those considered most significant in relation to
approaching the "ideal" waste form for underground storage.  Each cate-
gory was assigned a range of numerical ratings according to its signi-
ficance.  The wastes are then rated within each category according to
the severity of their hazards.  The reasoning used in assigning the
ratings is explained in the following discussion.

Category 1 - Flammable

The flammability hazards associated with each substance were considered
of extreme importance.  The storage of a highly flammable material
would  create a hazard too great for the safety and security of the mine
during handling and storage or in the event of a mine fire.  This
                                   92

-------
rating system was designed to classify all those materials which  pre-
sented significant flammability hazards as unacceptable for under-
ground storage without previous treatment.  Flammability hazards  were
assigned values of 0  through 7 according to their severity.

Materials Given A Flammability Rating Of 7 Include—

     1.   Highly flammable and/or explosive gases, liquids, or solids.
     2.   Materials which evolve highly flammable, explosive, and/or
          reactive gases upon contact with air, water, or slight  heat.
     3.   Materials which are highly reactive and will ignite, explode,
          or react to form highly flammable or explosive substances on
          contact with materials which may be found or stored in  the
          mine.
     4.   Materials forming flammable or explosive dusts or mists when
          dispersed in air.
     5.   Materials spontaneously flammable or explosive in air or water.

An example of a waste presenting a severe flammability hazard is Acro-
lein.

Materials Given Flammability Ratings Of 4 Through 6 Include—

     1.   Moderately flammable and/or explosive gases, liquids, or
          solids.
     2.   Materials which evolve moderately flammable, explosive, and/or
          reactive gases upon contact with air, water, or heat.
     3.   Materials which are less reactive and may ignite, explode, or
          react to form flammable or explosive substances on contact
          with materials which may be found or stored in the mine.

An example of a waste presenting a moderate flammability hazard is
Potassium Chromate which is a good oxidizer.

Materials Given Flammability Ratings Of 1 Through 3 Include—

     1.   Slightly flammable and/or explosive gases,  liquids,  or solids.
     2.   Materials which evolve slightly flammable,  explosive, and/or
          reactive gases upon contact with air, water, or heat.
     3.   Materials which are weakly reactive and could ignite, explode
          or react to form flammable or explosive substances on contact
          with other materials which may be found or stored in the mine.
     4.   Materials which are or form flammable,  explosive, and/or re-
          active substances only under special conditions.

An example of a waste presenting a slight flammability hazard is Aldrin
which is a pesticide that may or may not be flammable depending upon
the solvent used in formulation.

Materials given a flammability rating of 0 presented no significant
flammability hazard.
                                   93

-------
Category 2 - Explosive

The explosive hazards associated with each waste were considered of
extreme importance.   The handling and storage of highly explosive
wastes in an underground facility would present too great a hazard to
be accepted.  Many of the explosive wastes are extremely sensitive to
the slightest mechanical, electrical, or thermal shock and are much
more powerful than common explosives used in mining operations.  For
the purposes of this rating system, an explosive waste was also as-
sumed to be flammable and to evolve gases with heat, therefore, a sub-
stance rated here also received a rating in Category 1 and Category 4.
This rating system was designed to classify all those materials which
presented significant explosive hazards as unacceptable for underground
storage without previous treatment.  Explosive hazards were assigned
values of 0 through 7 according to their severity.

Materials Given An Explosive Rating Of 7 Include—

     1.   Highly explosive and/or violently reactive gases, liquids, or
          solids.
     2.   Materials which evolve highly explosive and/or violently re-
          active gases upon contact with air, water, or slight heat.
     3.   Materials which are highly reactive and will explode, react
          violently, or react to form explosive or violently reactive
          substances on contact with materials which may be found or
          stored in the mine.
     4.   Materials forming explosive dusts or mists when dispersed in
          air.
     5.   Materials spontaneously explosive in air or water.

An example of a waste presenting a severe explosive hazard is Diazodi-
nitrophenol (DDNP).

Materials Given Explosive Ratings Of 4 Through 6 Include—

     1.   Moderately explosive and/or reactive gases, liquids, or
          solids.
     2.   Materials which evolve moderately explosive and/or reactive
          gases upon contact with air, water, or heat.
     3.   Materials which are less reactive and may explode, react
          violently, or react to form explosive or violently reactive
          substances on contact with materials which may be found or
          stored in the mine.

An example of a waste presenting a moderate explosive hazard is Cadmium
Nitrate which is a good oxidizer.

Materials Given Explosive Ratings Of 1 Through 3 Include—

     1.   Explosive materials relatively insensitive to flame, spark,
                                   94

-------
           or  impact.
      2.    Materials which  evolve weakly  explosive  gases  upon contact
           with  air, water  or heat.
      3.    Materials which  are weakly  reactive  and  could  explode or re-
           act to  form explosive substances on  contact with materials
           which could be found or stored in  the mine.
      4.    Materials which  are explosive  or form explosive  substances
           only  under  special conditions.

An  example of a waste presenting a slight explosive hazard is Chlordane
which is a pesticide  that  may or may  not evolve explosive  hydrogen gas
if  heated  to  decomposition without ignition.

Materials  given an explosive rating of 0 presented no significant  ex-
plosive hazard.

Category 3 -  Evolve Gas In Air Or Water

This  category rates the degree of hazard associated with substances
which evolve  flammable, explosive, or toxic gases in air or water.   In
the event  of  a  mine flood  or accidental  container rupture, the  storage
of  these materials would present severe hazards to the safety of the
facility.  Although these  hazards are considered highly significant,
this  rating system was not designed to classify those wastes given the
maximum rating  as unacceptable for underground storage without previous
treatment  strictly on  the basis of this  category.   If the  gas evolved
is  strictly toxic and not  flammable or explosive,  the hazard rating
under this category is also qualified by a rating in Category 6 - Toxic.
However, if the gas evolved is flammable or explosive or both, the hazard
rating under  this category is also qualified by a rating in Categories
1 and 2.   This  means  that a waste with a rating in this category will
be  rated in at  least one other category as well.   For this reason, the
hazard ratings  in this category were valued from 0 through 3.  A hazard
rating of  3 indicates a severe hazard, a rating of 2 a moderate hazard,
and a rating  of 1 a slight hazard.

The ratings under Category 3 are based upon specific properties of a
material which  are:

      1.   The vapor pressure at ambient conditions.
      2.   The flammable and/or explosive limits in air.
      3.   The reactivity with air,  water, or oxidizable materials at
          ambient conditions.
      4.   The estimated 24 hour TLV in air.
      5.   The recommended provisional limit in air.

Materials Given A Hazard Rating Of  3 Include—

      1.   Materials whose vapors are highly flammable,  explosive, toxic,
          and/or reactive and have  high vapor pressures at ambient con-
          ditions .
                                  95

-------
     2.    Materials  which react  upon contact with air or water to
          evolve flammable and/or explosive gases in concentrations
          exceeding  their lower  flammable or explosive limits in air.
          If the data necessary  to classify a material under this cri-
          teria was  not available, the worst case was assumed and the
          material was given a rating of 3.
     3.    Materials  which react  upon contact with' air or water to evolve
          toxic gases in concentrations exceeding their 24 hour TLV in
          air.   If the data necessary to classify a material under this
          criteria was not available, the worst case was assumed and the
          material was given a rating of 3.
     4.    Materials  which react  upon contact with air or water to evolve
          highly reactive gases  which will ignite, explode, or react
          to form flammable, explosive, or toxic substances on contact
          with materials which may be found or stored in the mine.
     5.    Gases which are highly flammable, explosive, toxic, and/or
          reactive.

An example of a waste presenting a severe hazard of evolving a hazardous
gas in air or water  is Potassium Cyanide which will evolve flammable,
explosive, and toxic Hydrogen Cyanide gas on contact with air.

Materials Given A Hazard Rating  Of 2_ Include—

     1.    Materials  whose vapors are flammable, explosive, toxic, and/or
          reactive and have moderate vapor pressures in ambient air.
     2.    Materials  which react  upon contact with air or water to evolve
          flammable or explosive gases in concentrations less than
          their lower flammable  or explosive limits in air.
     3.    Materials  which react  upon contact with air or water to evolve
          toxic gases in concentrations greater than their recommended
          provisional limit but  less than their 24 hour TLV in air.
     4.    Materials which react  upon contact with air or water to evolve
          moderately reactive gases which may ignite, explode, or react
          to form flammable, explosive, or toxic substances on contact
          with materials which may be found or stored in the mine.
     5.    Gases which are moderately flammable, explosive, toxic, and/or
          reactive.

An example of a waste presenting a moderate hazard is Mercuric Sulfate
which evolves toxic fumes of Mercury in air but has a moderate vapor
pressure.

Materials Given A Hazard Rating Of 1 Include—

     1.   Materials whose vapors are flammable, explosive, toxic, and/or
          reactive and have low vapor pressures in ambient air.
     2.   Materials which are weakly reactive upon contact with air or
          water and may evolve flammable and/or explosive gases in con-
          centrations below their lower flammable and/or explosive lim-
          its in air.
                                   96

-------
      3.   Materials which are weakly reactive upon  contact with  air or
          water  to evolve toxic  gases  in concentrations below their rec-
          ommended provisional limit in air.
      4.   Materials which react  upon contact with air or water to  evolve
          weakly reactive gases  which may ignite, explode, or react to
          form flammable, explosive, or toxic substances on contact with
          materials which may be found or stored in the mine.
      5.   Gases  which are weakly flammable explosive, toxic,  and/or
          reactive.

An example of a  waste presenting a slight hazard is Mercuric  Chloride.

Materials given  a hazard rating  of 0 presented no significant  hazard of
evolving gases in air or water.

Category 4 - Evolve Gas With Heat

If materials stored in a mine evolved flammable, explosive, or toxic
gases when subjected to heat, the hazards involved in a mine  fire would
be significantly increased.   If  a flammable and/or explosive  gas were
evolved, a fire  might conceivably spread throughout the mine  in a
relatively short period of time.   If toxic gases were evolved, extin-
guishing a mine  fire would become much more difficult and hazardous.
With  this in mind, the hazard ratings under this category were based
upon  the following criteria:

      1.   The temperatures which would be attained in a mine fire.
      2.   The boiling point of a substance.
      3.   The temperature of decomposition of a substance.
      4.   The vapor pressure of a substance.
      5.   The flammable and/or explosive limits of a substance in air.
      6.   The estimated 24 hour TLV of a toxic substance in air.
      7.   The recommended provisional limit of a toxic substance in air.

The temperatures attained in a mine fire are controlled by  the type of
fuel, the availability of fuel,  and the availability of oxygen.  De-
pending upon the combinations of  these factors,  temperatures ranging
from a few hundred degrees centigrade to well over one thousand degrees
centigrade may be attained.   Due to the complexities and uncertainties
of this situation, temperature ranges were selected as a basis for
ratings in this  category.  The selection of these temperature ranges was
based upon two assumptions:

     1.   The probability of a mine fire attaining lower temperature
          ranges is greater  than  that of attaining higher temperature
          ranges due to the  types of fuel available.
     2.   A mine fire will pass through a low temperature range before
          reaching a high temperature range.

Therefore,  a substance which will evolve a hazardous gas in a low tem-
                                   97

-------
perature fire is classified as more hazardous than a substance which
requires a high temperature fire to evolve a hazardous gas.

Materials which evolve hazardous gases between 40° and 500°C (below
40°C rated in Category 3 - Evolve Gas In Air Or Water) were rated as
severe hazards, between 500° and 1,000°C as moderate hazards, and over
1,000°C as slight hazards.

The hazard ratings in this category were valued from 0 through 3 for
the same reasons of qualification as explained in Category 3.  A
hazard rating of 3 indicates a severe hazard, a 2 rating indicates a
moderate hazard, and a 1 rating indicates a slight hazard.

Materials Given A Hazard Rating Of 3 (Category 4) Include—

     1.   Materials whose vapors are flammable, explosive, toxic, and/or
          reactive and have boiling points between 40° and 500°C.
     2.   Materials which decompose at temperatures between 40° and
          500°C evolving flammable and/or explosive gases in concen-
          trations exceeding their lower flammable and/or explosive
          limits in air.
     3.   Materials which decompose at temperatures between 40° and
          500°C evolving toxic gases in concentrations exceeding their
          recommended 24 hour TLV in air.
     4.   Materials which decompose at temperatures between 40° and
          500°C evolving gases which are reactive and will ignite, ex-
          plode, or react to form flammable, explosive, or toxic sub-
          stances on contact with other materials which may be found
          or stored in the mine.

An example of a waste presenting a severe hazard is Ammonium Picrate
which autoignites at 423°C, evolving toxic fumes of nitrous oxides.

Materials Given A Hazard Rating Of 2 Include—

     1.   Materials whose vapors are flammable, explosive, toxic, and/or
          reactive and have boiling points between 500° and 1,000°C.
     2.   Materials which decompose at temperatures between 500  and
          1,000 C evolving flammable and/or explosive gases in concen-
          trations below their lower flammable and/or explosive limits
          in air.
     3.   Materials which decompose at temperatures between 500° and
          1,000°C evolving toxic gases in concentrations greater than
          their recommended provisional limit but less than their 24
          hour TLV in air.
     4.   Materials which decompose at temperatures between 500° and
          1,000°C evolving gases which are reactive and may ignite, ex-
          plode, or react to form flammable, explosive, or toxic sub-
          stances on contact with other materials which may be found or
          stored in the mine.
                                    98

-------
 An example of  a waste presenting  a moderate hazard is Cadmium.

 Materials  Given A Hazard  Rating Of 1  Include—

      1.    Materials whose vapors  are  flammable,  explosive,  toxic,  and/or
           reactive and have boiling points  above 1,000°C.
      2.    Materials which decompose at  temperatures  above 1,000°C
           evolving flammable and/or explosive  gases  in concentrations
           below their lower flammable or explosive limits in  air.
      3.    Materials which decompose at  temperatures  above 1,000°C
           evolving toxic  gases in concentrations  below their  recommended
           provisional limit in air.
      4.    Materials which decompose at  temperatures  above 1,000°C
           evolving gases  which are reactive  and may  ignite, explode, or
           react  to form flammable, explosive,  or  toxic  substances  on
           contact  with other materials which may  be  found or  stored
           in the mine.

 An example of  a  waste presenting  a slight hazard  is Lead Arsenite.

 Materials  given  a  hazard  rating of 0 presented no  significant hazard
 of evolving gases  with heat.

 Category 5 - Soluble  In Water

 The solubility of  a material in water was considered as a hazard for
 two main reasons:

      1.    A soluble material presented a much greater potential for
           migration out of the mine environment.
      2.    A soluble material would be much more chemically reactive
           with the lithology or with other materials stored in the mine.

Although these hazards are significant,  they do not present as great
a  short term hazard to the environment as do Categories 1 through 4;
hence, the  ratings in this category were given a value of 0 through 2.
A  rating of 2 indicates that a material is soluble above its recommended
provisional limit* in water and presents a severe hazard.  A rating of  1
indicates  that a material is soluble below its recommended provisional
limit in water and presents a moderate to slight hazard.  A rating of 0
indicates  a. material is insoluble  in water and presents no significant
hazard.  It should be noted that solubility in water can be affected by
pH, temperature, agitation,  and other factors.   For the purposes of this
rating, it was assumed that the water was at neutral pH, cool, and slow
moving to  stagnant.
 Equal to drinking water standard (see definitions).

Category 6 - Toxic

A toxic material has three principal methods by which it may enter the
human body:

     1.   Ingestion
     2.   Inhalation
     3.   Absorption through skin

For simplicity,  each of these methods of entry was considered to be
equally significant.  Since this rating system was designed to indi-
cate the degree of hazard, a material toxic by all three methods of
entry was assumed to constitute a greater threat to safety than one
toxic by only two methods, and given a rating of 3 to indicate a
severe hazard.   A material which was toxic by only two of the three
methods was considered a moderate hazard and was given a rating of 2.
A material which was toxic by only one method was considered the
least hazardous and given a rating of 1.  A nontoxic waste was given a
rating of 0.  Although the hazards associated with a material due to
its toxicity are significant, this rating system was not designed to
classify a material as unacceptable underground without pretreatment
strictly on the basis of its toxicity.

After a waste is rated in each of the six categories, the sum of the
individual ratings make up a waste's total hazard or Hazard Index
(H.I.)*  This number indicates the acceptability of a waste for under-
ground storage without previous treatment.  The lower the Hazard Index
the more acceptable a waste becomes.

Appendix B-2, Hazard Index of Candidate Wastes, presents the indivi-
dual ratings of each waste and its total hazard or Hazard Index.  If
data concerning the hazards of a particular waste was not available,
rating the waste became a judgemental decision.  In the event such a
decision was necessary, the worst case was assumed.  Although an at-
tempt was made to make this rating system as objective as possible to
aid in future use, a certain amount of subjectivity was unavoidable
due to a lack of information.  However, when sufficient data on wastes
and waste streams becomes available, such subjective decisions will no
longer be necessary.
STEP 5 - FIRST SCREENING

The purpose of the first screening was to divide the wastes into groups
according to their Hazard Index.  The results of this screening are
presented in three tables:

     1.   Table 4, H.I. = 0-5, CONTAINERIZATION ONLY, lists the wastes
          which require no previous treatment, other than containeri-
          zation, to be acceptable for underground storage.
                                  100

-------
          Table 5, H.I. = 6-9, OPTIONAL TREATMENT, lists wastes which
          are acceptable for underground storage in containers but may
          warrant treatment to a less hazardous form if the risks pre-
          sented by pure-form storage are considered too great.
          Table 6, H.I. = 10-25, MANDATORY TREATMENT, lists the wastes
          which, based upon the criteria adopted for this study, are
          unacceptable for underground storage in containers without
          previous treatment.

STEP 6 - TREATMENT PROCEDURES

Once the wastes had been screened according to the severity of their
hazards, an attempt was made to compile treatment procedures for the
candidate wastes.  The purpose of these procedures was to reduce the
wastes to the level exhibiting the least potential danger to the en-
vironment.  In Appendix B-3, this level is presented as the "Ideal
Form".  Although the waste form attained at this level presented the
least hazard, it was not the only form acceptable for underground stor-
age.  Since the basis of acceptability was a Hazard Index of less than
ten, many of the wastes were acceptable before or during treatment with-
out being in their "Ideal Form".  This level is presented as "Accep-
table Form" in Appendix B-3 and represents the minimum mandatory level
of treatment required for a waste to be acceptable in an underground
environment.  The point at which this level of treatment is reached is
indicated by the heavy line on each form in Appendix B-3.  Since some
hazards are still present in the "Acceptable Form" and treatment to the
"Ideal Form" may be uneconomical, a cost—benefit analysis to determine
the proper level of treatment prior to storage would be required.  How-
ever, since economic evaluations were not within the scope of this study,
it was assumed that the "Acceptable Form" would be placed underground.
Subsequent treatment towards the "Ideal Form" was considered as op-
tional .

It should be noted that volume reduction by filtration was considered
as a mandatory treatment step, except when soluble,  toxic compounds
were present, to provide for the most efficient use of available mine
space.  In addition, two pages have been included in Appendix B-3 for
some explosive wastes to allow for their treatment as obsolete muni-
tions.  Since munitions require primers as well as explosive charges,
they may contain toxic materials not found in explosive manufacturing
wastes.  In accordance with the "worst case" philosophy,  these materials
were assumed to be present and treatment procedures  were postulated ac-
cordingly.


STEP 7 - SECOND SCREENING

The purpose of the next screening process was to obtain a list of all
possible acceptable waste forms for storage whether  they be treated or
untreated.  This screening was based upon the results of the treatment
of the wastes.  The information generated by this screening is presented
in the following tables:

     1.   Table 7, CANDIDATE WASTES WHICH ARE ACCEPTABLE FOR UNDER-
          GROUND STORAGE IN CONTAINERS WITH NO TREATMENT, lists all the
          wastes of concern with a Hazard Index of less than ten.
     2.   Table 8, CANDIDATE WASTES WHICH ARE ACCEPTABLE FOR UNDER-
          GROUND STORAGE IN CONTAINERS AFTER TREATMENT, lists all the
          wastes of concern which must be treated and whose treatment
          products are toxic, but acceptable for underground storage.
                                   103

-------
     3.   Table 9,  CANDIDATE WASTES WHICH MUST BE TREATED AND WHOSE
          TREATMENT PRODUCTS ARE ESSENTIALLY NONTOXIC.   UNDERGROUND
          STORAGE OF PRODUCTS IS OPTIONAL, lists the wastes which must
          be treated and whose treatment products are essentially non-
          toxic, but may present a risk to the environment if disposed
          of freely.  A material such as salt (sodium chloride)  is
          basically nontoxic, but would constitute a threat to the
          environment if it was disposed of in concentrated form with
          no control.  The underground storage of such materials is ac-
          ceptable, but may not constitute the best use of available
          mine space and is, therefore,  considered optional.
     4.   Table 10, CANDIDATE WASTES FOR WHICH TREATMENT WAS UNAVAIL-
          ABLE OR INSUFFICIENT AND REQUIRE FURTHER STUDY, lists  all the
          wastes of concern which must be treated, but which were not
          acceptable for storage utilizing current treatment procedures.
          These wastes might be acceptable at a later date if treatment
          procedures can be developed or improved, or if different risk
          values are assigned.  It is a recommendation of this study
          that research in this area be carried out.

     5.   Table 11, CANDIDATE WASTES WHICH ARE NOT RECOMMENDED FOR
          UNDERGROUND STORAGE IN ANY FORM, lists the wastes which are
          not acceptable for underground storage in either their
          treated or untreated form.

STEP 8 - WASTE INTERACTION AND COMPATIBILITY

Once a waste has been placed underground, the possibility of environ-
mentally hazardous compounds being formed by chemical reactions among
the stored wastes must be assessed.  It was assumed that, in the event
of a mine flood, the containers would rupture allowing the wastes to
go into solution.  Although this situation could be prevented by pro-
per treatment and containerization, the "worst case" philosophy was
employed.  Under these conditions, the number of potential chemical
reactions is staggering.  Due to the enormous number of possible re-
actions, consideration of only the immediate or first level reactions
was within the scope of this study.  However, further research in
this area is recommended.

In an attempt to evaluate the types of reactions which might occur,
a waste interaction matrix utilizing the "Acceptable Form" was devel-
oped and is presented in Figure 20.  The reactions in this figure are
described as hazardous and nonhazardous.  A hazardous reaction is one
in which either of the following might occur:

     1.   The potential for migration of a waste is increased by the
          formation of a more soluble toxic compound.
     2.   Any new substances are formed which present greater hazards
          to the environment than the original substances.

In a nonhazardous reaction the reverse of the above is true.  The
hazardous reactions which may occur are explained in Table 12, Pages
109 through 113.

The arsenites can react with cacodylic acid to
form the cacodylate and arsenic trioxide.  The
greatest hazard associated with allowing these
reactions to occur is that arsenic trioxide is
formed.  This compound has been given a hazard
index of 7 (Appendix B-2) which classifies it as
being optionally acceptable underground in its
pure. form.  The main reasons for its optional
acceptability are that arsenic trioxide sublimes
at 193°C and is soluble in water.

The only hazards associated with the potassium
hydroxide reactions is that the resulting com-
pounds of potassium are toxic,  and are more
soluble in water than the original compounds.
Because of the increased solubility, there is
a greater potential for migration from the mine
or for further reaction with other substances.
These compounds, however, would still be accept-
able for storage if they could be recontainerized.
If not naturally occurring, potassium hydroxide
would occur underground only as a treatment pro-
duct of potassium dinitrobenzfuroxan (KDNBF) (as
munitions) and cadmium potassium cyanide.

The only hazards associated with the sodium hy-
droxide reactions is that the resulting com-
pounds of sodium are toxic, and are more soluble
in water than the original compounds.  This solu-
bility does increase their potential for migration
out of the mine, but does not render them unac-
ceptable as long as they can be properly contain-
erized.  Sodium hydroxide may occur underground as
a product of the treatment of arsenic trichloride
or lewisite.  Since both of these substances re-
quire mixing with a base at some point in their
treatment, either sodium hydroxide or calcium hy-
droxide may be used.  Calcium hydroxide is pre-
ferred since the calcium compounds formed are
less soluble than the sodium compounds, although
both are storable underground.  It is probable,
therefore, that sodium hydroxide would not be
found as a treatment product underground, how-
ever, its possible use is not precluded.

The only hazard associated with these reactions is
that the calcium arsenite formed is more soluble
than the zinc arsenite.  Although calcium arse-
nite is more soluble and has a greater potential
for migration out of the mine, it is still an ac-
ceptable form for underground storage if properly
containerized.  Calcium hydroxide may occur under-
ground as a product of the treatment of antimony
pentafluoride, antimony trifluoride, arsenic tri-
chloride, fluorine, GB, or lewisite.  Calcium sili-
cate occurs only as a treatment product of fluorine
if the fluorine is contaminated with silicon tetra-
fluoride prior to treatment.

Benzene hexachloride is dehydrochlorinated to
trichlorobenzene in the presence of alkali.
The trichlorobenzene is probably less toxic but
it would create a slightly greater flammability
hazard than the benzene hexachloride.  Tri-
chlorobene would be classed as optionally accept-
able for underground storage  in proper containers
due to its slight flammability and potential for
liberation of toxic, flammable, and possibly ex-
plosive gases when heated to  decomposition.

Lead oxide in the presence of water and potassium

These arsenites hydrolize in water to form a strong
base and weak arsenous acid.  The strong base may
react with 2, 4-D to form the more soluble potas-
sium or sodium salt of 2, 4-D.  The strong base
catalyzes the hydrolysis of guthion or demeton
to form a more soluble hydrolysis product.  This
soluble product may be nearly as toxic as the
original compound.
The result of this reaction may be a sodium chlo-
ride-lead oxide complex.  This complex is soluble
and constitutes a greater hazard than the original
PbO.

     Discretion should be used when the substances included as the initial reactants in reactions A through
     SS are being stored underground.  There is a possibility of more hazardous compound being formed if a
     reactant is stored in proximity to some other reactant.  It is therefore recommended that the sub-
     stances mentioned above not be stored in proximity to each other underground.

As a result of this investigation, it was found that most of the
hazardous reactions increased the solubility of the wastes.  The ram-
mifications of this type of reaction are twofold.  In the short-term,
an increase in solubility would result in an increase in chemical re-
activity thereby increasing a waste's potential to take part in fur-
ther reactions.  In the long-term, an increase in solubility would in-
crease the potential of a waste to migrate from the mine environment
by keeping the waste in solution for a longer time.  It should be
stressed that the interaction of the wastes can be controlled through
proper treatment and containerization thereby maximizing the protec-
tion of the environment.
STEP 9 - GEOCHEMICAL INTERACTION AND COMPATIBILITY

The purpose of the geochemical study was to determine the compatibility
of the geological and chemical investigations in a field condition.
Since environmentally unfavorable reactions may occur from the chemi-
cal interaction of the stored wastes with the receiving geological
formations, this evaluation was a necessary step in determining the
environmental acceptability of the concept.  An unfavorable reaction
would be one in which any of the following might occur:

     1.   The potential for migration of a waste is heightened by an
          increase in its solubility through complexing or ioniza-
          tion.
     2.   The structural integrity of the lithology is unfavorably
          altered.
     3.   Any new substances are formed which present greater hazards
          to the environment than the original substances.

In a favorable reaction, the reverse of the above would be true.  If
an unfavorable reaction occurs, a waste is said to be incompatible in
a lithology.  If a favorable reaction or no reaction occurs, a waste
is said to be compatible in a lithology.

The lithologies which have been selected as candidate formations for
storage are:

     1.   Rock salt (Halite)
     2.   Gypsum
     3.   Potash (Sylvite)
     4.   Shale(l) (Relatively high montmorillonite content)
     5.   ShaleC2) (Relatively low montmorillonite content)
     6,   Limestone
     7.   Granite

For the purposes of this analysis, it was assumed these lithologies
were homogeneous in composition and that any impurities which would
normally be found with them would not occur in amounts sufficient to
                                  114

-------
alter the basic reactions between the wastes and the lithology.

In this investigation, the "worst case" analysis was again employed.
In this analysis, the storable wastes were assumed to be in contact
with the selected lithologies under both wet and dry conditions.
These conditions would not be possible unless the waste containers
were ruptured by some calamity such as flooding.  The resulting re-
actions were classed as favorable or unfavorable.  Although the con-
ditions allowing the interaction of the wastes and receiving forma-
tions could be controlled through proper treatment and containeri-
zation, this analysis was performed to ensure the appraisal of all
conditions which might adversely affect the environment.

The discussion of the types of reactions which may occur should be
qualified by stating that all the reactions, with the exception of
chloride complexing, are relatively slow.  Years may be required be-
fore any detrimental effects on the environment are realized.   How-
ever, since both long and short-term effects are within the scope of
this study, these reactions were assessed.

It should be noted that the reactions presented here are only the im-
mediate or first level reactions.  As with the interaction of the
wastes, the enormous number of possible chain reactions precludes
their investigation within the scope of this study.  However,  further
research in this area is recommended.

Rock Salt (Halite) And Potash (Sylvite)

Rock salt and potash are grouped together because of similarities in
chemical behavior.  The principal constituents of rock salt and potash
are readily soluble in water to form a solution of near neutral pH.
If toxic ions are present in this solution,  highly soluble chloride
complexes will form.  The rate at which these complexes are formed
depends upon the availability of the toxic ions which,  in turn, de-
pends upon the amount of the original toxic  compound and the pH of
the solution.  For example, if Lead Oxide (PbO)  were to come into
contact with a solution containing dissolved rock salt  or potash at
neutral pH, the rate of complexing would be  slow because PbO is not
readily ionized at neutral pH.  However,  if  the pH of the solution was
varied from neutral by the presence of another waste,  the rate of
complexing would increase with the degree of variance due to the larger
availability of lead or plumbite ions created by the change in pH.
Since chloride complexing creates toxic compounds which are more sol-
uble than the original toxic compounds and thereby are potentially more
hazardous, wastes which would take part in such reactions are  classed
as being incompatible in rock salt or potash.

Gypsum

Although reactions between some of the storable wastes and gypsum did
                                  115

-------
occur, none were found to be of an unfavorable nature.  For this
reason, all of the wastes found acceptable for storage are compatible
with this lithology,

Shale

Principally, there are two types of unfavorable reactions which may
occur in shales (1) and (2).  In the presence of a solution which con-
tains sodium ion, the montmorillonite in shales (1) and (2) exhibits
thixotropic properties (deflocculates into a jelly-like material) re-
ducing the structural capabilities of the entire shale.  Due to this
unfavorable alteration, wastes having the potential for releasing
sodium ions in solution are classed as incompatible in shale (1) or
(2).  In the presence of a solution of low pH (acidic), the montmoril-
lonite in shales (1) and (2) undergoes a change in composition.  Al-
though the results of this change are not necessarily unfavorable,
potentially unfavorable alterations in the structural stability of
the shale during the change may take place.  For this reason, wastes
with the potential of forming acidic solutions, or which are in them-
selves acidic solutions, are classed as incompatible in shale  (1) or
(2).

The rate of these reactions depends upon the amount of available sur-
face area of shale, the permeability of the shale, the concentration
of ions in the waste solution, and the ion exchange capacity of the
shale.  An increase in these factors will bring about an increase in
the rate of reaction.  Since some of these factors may be increased
by an increase in the montmorillonite content of a shale, shale (2)
may generally be said to be a more favorable lithology for the storage
of hazardous wastes.

Limestone

Unfavorable reactions occur in limestone in the presence of solutions
of low pH (acidic).  The limestone is dissolved by the acid solution
with the liberation of C02.  With an increase in the strength of the
acid, the rate of this reaction increases with a correspondingly greater
amount of CC^ evolvement.  Since dissolving the limestone decreases its
structural capabilities, a reaction of this type would be unfavorable.
For this reason, wastes with the potential of forming fairly strong
acidic solutions, or which are in themselves fairly strong acidic solu-
tions, would be classed as incompatible in limestone.

Granite

In the presence of solutions which are acidic, the potash feldspar
minerals in granite undergo hydrolysis and are changed into different
minerals.  In the presence of solutions which are basic  (above pH 9),
the solubility of  the silica minerals in granite increases abruptly due
to lonization.  These reactions would be unfavorable because the struc-
                                   116

-------
tural capabilities of the granite would be reduced.  For this reason,
wastes which would form strongly acidic or basic solutions or which
are in themselves strongly acid or basic solutions, would be classed
as incompatible in granite.  It should be noted, however, that the rate
of the hydrolysis reaction in granite is very slow.  This rate of re-
action depends upon the pH of the solution and the degree of fractur-
ing in the granite.  The greater the extent of either of these factors,
the greater the rate of reaction.

To illustrate the types of reactions which may occur and the com-
patibility of the stored wastes and lithologies, two matrices have
been developed and are presented in Table 13 and Table 14.
STEP 10 - WASTE MIGRATION

The primary result of the investigation of the potential environmental
effects of waste migration is that migration can be avoided if the
proper techniques of waste treatment and containerization are employed.
Since the goal of underground storage is the complete isolation of the
hazardous wastes from the biosphere, the potential migration of the
wastes must be controlled.  From a chemical point of view, there are
two principle methods by which a waste may migrate.

     1.   Carried by ground water.
     2.   Reacting with host rock.

Both of these methods are primarily controlled by the solubility of a
waste.  Therefore, decreasing the solubility of a waste during treat-
ment should be of major concern.  Perhaps the best method of avoiding
migration is through the use of containers.  If a stored waste is
never allowed to contact the mine environment, there would be no chance
of it escaping.  The disadvantage of containers is that their use could
become economically prohibitive.  It is recommended that research in
the area of the containerization or encapsulation of the wastes be
done to determine the controlling economic factors.

It should be noted that, if a waste should escape the container, the
rate of migration by ground water or reaction with the lithology is
extremely slow, ranging from several hundred to thousands of years.
The tendency of ground water, in most cases, is to move into a mine
rather than out and, as mentioned in Step 9, waste/lithology reactions
do not proceed quickly.  However, the eventual effects of the migration
of a waste once it leaves the mine environment are not known.  The
rate of movement, the distance a waste will travel, and the potential
chemical changes in the waste or environment which may take place
vary from site to site and will require further research.  Research in
this area is a recommendation of this study.

STEP 11 - PROJECTED WASTE VOLUMES

The last step in evaluating the wastes as candidates for underground
storage is to investigate their probable volumes.   This is important
in order to obtain some idea of the magnitude of the problem of waste
disposal and to assess mined storage as a potential answer.  In ac-
cordance with the contract directive, current waste volumes were ob-
tained from available sources and projected to estimate the volumes of
waste in the years 1975, 1980, and 1985.  This work is presented in
Appendix B-4.  The information contained in Appendix B-4 is subdivided
by industries identified by their Standard Industrial Classification
Code (SIC Code).  Under each industry heading are listed the wastes
which are either produced or used by that industry and would probably
appear in its waste streams.  Immediately following is the geograph-
ical percentage distribution of the wastes from that industry as ob-
tained from available sources.

The order in which the wastes are listed under each industry heading is
significant.  The initial group of wastes contains those which are ac-
ceptable for underground storage in containers with no pretreatment.
The second grouping of wastes contains those which are acceptable for
underground storage in containers after treatment.  The third grouping
contains all other wastes.  A lack of reliable information was en-
countered in this task.  Much of the available data was incomplete, and
inconclusive.  Although conclusions were attempted from this data, it
must be noted that these conclusions, may be inaccurate.  Extensive re-
search in this area is sorely needed.  It is a recommendation of this
study that this research be accomplished.

Although distribution data was available in some cases, it was not pos-
sible to quantify the volumes of candidate wastes from the following
industries.

     1.   SIC 10 - Metal mining.
     2.   SIC 24 - Lumber and wood.
     3.   SIC 2834 - Pharmaceutical preparations.
     4.   SIC 32 - Stone, clay, glass, and concrete products.
     5.   SIC 33 - Primary metals industries.
     6.   SIC 3573 - Computers.
     7.   SIC 36 - Battery manufacture, electronics, mechanical, magne-
          tic tape production.
     8.   SIC 49 - Electric, gas, and sanitary services.

One result of the volume study was that some of the wastes did not occur
in significant amounts.  In such cases, it may be more feasible to treat
these wastes at the point of origin.  Table 15 lists the wastes of con-
cern which occur in negligible amounts.  Although these wastes did not
occur in significant volumes, they were screened for acceptability on
the same basis as other wastes to account for the possibility of a fu-
ture increase in generation.

To summarize the results of waste characterization, Figure 21 was de-
veloped.  These results indicate that 99.99 percent of the total
treated and untreated candidate waste volume is acceptable for under-
ground storage.  The volume of unacceptable wastes occurs almost en-
tirely from the use of Mercury and its compounds.   Since the use of
Mercury is presently declining, the percentage of  problem solution
offered by the underground storage of hazardous wastes is believed to
be valid.

                                SECTION 7

                    DETECTION, MONITORING AND CONTROL
The emplacement, storage, and management of noxious chemical wastes in
underground mined openings will require continuous surveillance of the
mine opening, contiguous subsurface areas, and surface environments.
The purpose of mined storage is to safely isolate hazardous wastes from
the biosphere.  The implementation of detection monitoring and control
systems will help insure isolation and safety by providing early warning
of contamination in air and water and will also allow early detection of
structural fatigue.  By these means the potential for waste interaction
with the biosphere can be strictly controlled.
MINE ATMOSPHERE

The basic requirements of a detection, monitoring, and control system
will include the following:

     1.   Continuously monitor, sample, and clean the circulating mine
          air.
     2.   Provide immediate response (alarms, etc.) to critical changes.
     3.   Indicate long-term finite changes.
     4.   Allow source area identification.
     5.   Provide qualitative and quantitative analysis of contaminants
          in air and water.
     6.   Provide high reliability.
     7.   Be adaptable to change and improvement as the technology ad-
          vances .
     8.   Provide decontamination capability.
     9.   Allow recovery and storage of released wastes.

The criterion that wastes be containerized prior to emplacement is due
partly to the problem of safe transport and storage in a closed environ-
ment.  Many of the wastes have very low TLV's; thus, even minor re-
leases are potentially very serious.

The contaminants may occur as particulates or gases and can be monitored
and controlled using several available techniques.  Appendix C lists
some of the instruments and techniques which are commonly used or pres-
                                   133

-------
ently being developed.   Many of these methods may be integrated to pro-
vide a wide range of coverage and control.

In researching the subject,  it was apparent that the state-of-the-art
is rapidly evolving with new and improved instruments and techniques.
It is expected that much of  the future technology will be adaptable to
the special needs of mined waste storage.
PHYSICAL MINE STRUCTURE

The importance of monitoring the short and long-term structural in-
tegrity of a mine used for housing hazardous wastes involves several as-
pects of this storage concept.  Of immediate interest is the safety of
personnel working in the facility.  Such things as roof falls, slabbing,
etc. are hazards which can normally be prevented by good maintenance
practices.  Hazards of a larger consequence would result if such fail-
ures were to rupture containers.  If this occurred, not only would mine
personnel be put in jeopardy, but the entire waste facility might be
lost temporarily, or even permanently.  To guard against such an occur-
rence, mines must be selected with high regard to stability; and to pro-
vide additional insurance, various monitoring instruments and techniques
should be implemented.  Instruments which are presently available can
provide finite measurements of short and long-term changes and thus
allow preventative measures to be taken before failure occurs.

The first step undertaken should be to conduct high-level surveys of the
mined space.  Such surveys can then be used as standards for comparing
future surveys to assess possible alterations.  Modern laser technology
might prove valuable in this type of program; however, specific instru-
mentation and techniques may have to be designed to fit the problem.

Most commonly available instruments are designed to measure finite
changes in stress  (load), strain  (deformation), convergence, and micro-
seismic movement.  Extensometers are proven detectors of low magnitude
deformation of supporting structures.  They can be permanently (or tem-
porarily) installed in any critical area, including roof, walls, pillars,
and floor.  Measurements can be made periodically on location, or they
can be designed for remote telemetry and monitored at any time.  In-
stallation is relatively simple, and the cost is low to moderate de-
pending on the system required.

Other monitoring instruments are capable of measuring finite convergence
between roof and floor, walls, pillars, etc.  There are many such detec-
tors available to  provide several levels of control and most are, or can
be, remotely monitored.

Geophones are used to detect  the minute movements indicative of released
stress and strain.  By noting  changes  in microseismic frequency and
magnitude, potential problems  can be detected early.  All of these de-
vices can be adapted  to remote monitoring telemetry.
                                   134

-------
A complete  structural monitoring system will be vital to a mined storage
facility  from the  standpoints  of safety, containment and retrievability.


AREA HYDROLOGY

The hydrologic environment in  the area of a hazardous waste storage
facility  will require monitoring to assure isolation of the wastes and
protection  to the  environment.  Streams, springs, and wells in the
vicinity  can  be physically sampled using standard methods and the sam-
ples then analyzed in a laboratory.

All significant aquifers in proximity to the mine should be identified
and their physical features established.  Such studies should determine
if subsurface water is migrating and, if so, in what direction and at
what rate.  In addition, natural static pressure, upper and lower lim-
its, and  natural particulate load (salinity) should be determined.   The
salinity  analysis  should be thorough since it will be useful as a stan-
dard for  future analysis.  Once these hydrologic parameters are de-
termined, perimeter monitoring wells can be sited.  The best configura-
tion will depend on the previous investigations, but at least two peri-
meters should be included for adequate control.  The total number of
wells needed  will  vary from site to site.

Most systems  used  to monitor migrating subsurface water include peri-
meter monitoring wells for physical sampling.   Since these wells are
typically small diameter, in-hole instrumentation is limited to small
probes.   Available  instruments which can be used continuously or period-
ically and monitored remotely or in the field were developed to measure
water level changes, conductivity,  PH, and temperature.   Probes to mea-
sure other physical parameters also exist,  or can be developed as the
need is recognized.

High-level monitoring techniques require water sampling for laboratory
analysis.  Many of  the instruments  described in Appendix C can be used
for this  purpose.

Mine water, if  it occurs naturally  might be controlled using sumps.   A
mine opening  will alter the natural hydrostatic environment when aquifer
communication exists.   Since the mine space is at atmospheric pressure,
aquifers  surrounding the opening will tend to drain toward the mine as
long as it is  open.  Should contamination of mine water occur, migration
away from the mine  opening will be  naturally retarded.

that the state-of-the-art is adequate to meet the requirements and con-
ditions of mined waste storage.  Available and developing instrumenta-

                                SECTION 8

                          REGULATION ASSESSMENT
Many existing laws and regulations are related to hazardous and poten-
tially hazardous substances that could affect the quality of our en-
vironment.  The objectives of these laws are, in general, to improve the
quality of the environment and to protect it from further pollution by
establishing national standards.  Some of these laws are related to dis-
posal of waste products, however, no laws or regulations were found to
directly govern the disposal or storage of hazardous waste products in
underground salt deposits and/or mined openings.

The approach to determining what Federal and State laws and regulations
may apply to governing the handling and storing of hazardous waste ma-
terials was to first review the Federal statutes and then identify those
laws relating to the different forms of waste products and hazardous and
poisonous substances.  The state statutes were then reviewed to deter-
mine which states have laws and regulations that relate to the Federal
standards.

The Federal government has passed many laws and regulations to cover
most possible forms of pollution to our environment.  Some of these
statutes and subsequent standards apply to hazardous waste products that
could effect the environment.  The Federal acts that fall within the
scope of this study and apply to hazardous waste disposal or storage are:
the Clean Air Act, The Solid Waste Disposal Act, The Federal Water Pollu-
tion Act of 1972, and the Federal Environmental Pesticide Control Act of
1972.  The Federal agencies responsible for administering these acts
must justify major actions under the National Environmental Policy Act
(NEPA) of 1969.  These five major acts, their objectives, areas and me-
thods of control, and provisions for their enforcement are summarized
in Figure 22.  The NEPA requires that the standards for all federal
statutes relating to governing pollution to the natural environment be
approved or established by the Environmental Protection Agency  (EPA).
This requirement along with the environmental impact statement provide
the EPA with some control over substances which may be hazardous to the
natural environment.  However, the EPA's only method of enforcement is
apparently through their standards and specified regulations for handling
and enforcement through other federal statutes and agencies.  The only
                                    138

method for enforcement found in the four areas of this review is through
the Federal Water Pollution Act, where EPA permit approval requires in-
dustry to report their monitoring data and states to enforce compliance
with the permits, backed by "substantial" civil and criminal penalties.

All of the states have air and water pollution laws, and most have solid
waste and pesticide laws as shown in Table 17.  A detailed study of each
of these laws and regulations is beyond the scope of our review, how-
ever, many of these statutes have been ammended to comply with Federal
s tandards.

In addition to the above statutes and regulations, the Federal Metal and
Nonmetallic Mine Safety Act (30 U.S.C. 725) provides some standards to
protect miners from hazardous materials stored in the mines.  These
safety standards relate to the storage of hazardous solids, liquids, and
gaseous materials that are generally used in the mining operations and
possibly could be applied to waste products.  These specific regulations
are:

                            Underground Mines

     57.16  Materials storage and handling.
                     General Surface and Underground

     57.16-3  Mandatory.  Materials that can create hazards if
     accidentally liberated from their containers shall be stored
     in a manner that minimizes the dangers.

     57.16-4  Mandatory.  Hazardous materials shall be stored in
     containers of a type approved for such use by recognized agen-
     cies; such containers shall be labeled appropriately.

     57.16-12  Substances that react violently or liberate dangerous
     fumes when mixed should be stored in  such a manner that they
     cannot come in contact with each other.

 In  general, federal control of  the storage and/or disposal of hazardous
waste products in mines or underground salt deposits  to protect our en-
vironment is a relatively new concept resulting from  the NEPA.  A  pro-
posed Hazardous Waste Management Act  of  1973 was  introduced in  the U.S.
 Senate  and in the U.S. House of Representatives to provide Federal regu-
 lation  in the treatment and disposal  of  certain hazardous wastes.  Both
 the Senate and the House have referred this proposal  to committees where
 it  is still  in the legislative  process.

 This review  found many  laws and regulations related to hazardous sub-
 stances,  however, none  of  these statutes appear  to  apply directly  to con-
 trolling the  storage  and management of hazardous  waste  in  underground
                                   140

mine openings.  There is a need for legislation to provide guidelines
for controlling the handling, transportation, storage, and management
of hazardous wastes in underground mines on a long-term basis in order
to protect our environment for future generations.

                              SECTION 9

                             MINE DESIGN
The concept of long-term storage of hazardous industrial wastes in
underground mines appears feasible and might be preferred to surface
storage for several important reasons.  Among these are:

     1.   It is well protected.
     2.   It provides permanent, very-long term containment.
     3.   Valuable surface area is not used.
     4.   It provides good security and control of access.
     5.   It requires a minimum of maintenance.
     6.   Storage space can be continuously expanded.
     7.   There is less chance of damage to the environment in case of
          a spill.
     8.   The facility could possibly be designed to survive a nuclear
          blast.
     9.   It is protected from the ravages of the weather.
    10.   A nearly constant temperature exists underground.
    11.   Humidity would not vary excessively.
    12.   The waste would be out of sight.
    13.   It is less subject to sabotage.

There are many different types of mines existing today that have been
excavated using numerous mining methods.  Of the many mining methods
in use, the room and pillar method appears to be best suited to the
storage of wastes underground.  The room and pillar method consists of
mining a number of parallel rooms (drifts) in the formation and con-
necting them by means of another series of parallel rooms (crosscuts)
mined at right angles to them.  The room and pillar mining method is
generally reserved for deposits that can be mined nearly horizontal.

Some advantages of the room and pillar mine as opposed to other types
that could be used for hazardous waste disposal include:

     1.   The mine layout is usually near horizontal or has a low dip
          with the underground workings generally all on one level.  In
          most cases the grade is shallow enough to permit the use of
          rubber tired equipment.
                                  144

-------
     2.   The  rooms  are  generally large.
     3.   Large  equipment  can be used if required to handle heavy
          or bulky loads.
     4.   The  mine is  relatively simple to excavate.
     5.   The  mining plan  provides for considerable flexibility in
          overall layout.
     6.   Mine ventilation is simplified.
     7.   Mine haulage is  simplified.

Room and pillar  mines  have been and can be excavated in several dif-
ferent types of  rock.  Rock types that might be suitable for the safe
underground storage  of hazardous industrial wastes are:  salt, shale,
limestone, dolomite, gypsum, potash, and granite.
IMPORTANT FACTORS TO BE CONSIDERED IN THE
DESIGN OF A HAZARDOUS WASTE STORAGE FACILITY

There are numerous factors which are important in the design of a
hazardous waste storage facility in rock.  Many of these optimal design
criteria would apply no matter what type of mine or rock formation the
facility was constructed in.  Some of the more important factors to
consider are listed below:

Public Acceptance

1.   The public must be informed of the need for a facility.
2.   Public hearings should be conducted both during and after an in-
     formation and education program is conducted.
3.   The general public, politicians, owners and operators of mines,
     and land owners must be convinced that a proposed facility in a
     given area is in their best interest as well as in the nation's
     best interest.
4,   A public information program should be a continuing thing during
     design, construction, and operation of such a facility.

Geological Factors

1.   Depth from the surface to a suitable rock formation.
2.   The type and character of the formation at the mining interval.
3.   Formation thickness in the storage zone.
4.   Permeability and porosity of the formation in the storage zone.
     It is preferable that the rock be dry.
5.   Chemical characteristics of the formation in the storage zone.
     The hazardous waste must not react adversely with the rock.
6.   The character of the rock above the storage zone.
7.   The local citizenry should agree to construction of a hazardous
     industrial waste storage facility in their area.
8.   The mine must have two shafts in order to comply with safety codes.
9.   Adequate ventilation must be provided to the underground facility.
                                  145

-------
10.   The site must be accessible to transportation facilities suitable
     for handling the anticipated volumes  and types of hazardous waste
     to be stored.
11.   It should be possible to construct  relatively large rooms in the
     rock formation selected.  This is necessary in order that large
     equipment and possibly large waste  containers could be handled
     underground.
12.   The site should be provided with an adequate supply of labor, water,
     and power.
13.   The storage operation must not conflict with any other operations
     such as oil and gas wells, and other  mines.
14.   The total quantity of waste to be stored and the rate at which it
     must be accepted by the storage facility must be known.  Those
     factors will determine the size of  the surface plant, shaft hoisting
     facilities, underground haulage facilities, and amount of available
     space.
15.   Means should be provided for removing the waste in the future if
     requested.
16.   In addition, if it is an existing mine:

     A.   Management and owners of any existing mine must agree to in-
          stallation of a hazardous waste  facility on their property.
     B.   The hazardous waste storage area must be completely isolated
          from the producing section of  the operating mine.
DESIGN FACTORS TO CONSIDER FOR AN
IDEAL STORAGE FACILITY

There are several other design factors that, if complied with, would
result in a more ideal underground hazardous waste storage facility.
These are:

     1.   It should be a room and pillar mine.
     2.   It is an operating mine with large mineable reserves.
     3.   The prospects for continued operation of the mine and marketing
          of the product are excellent.
     4.   The rock be essentially homogeneous.
HANDLING AND PLACEMENT OF
HAZARDOUS WASTES

Hazardous waste products can be stored in existing mines, both active
and inactive, or in new mines developed principally for hazardous waste
storage.  In order to convert these mines into waste storage facilities,
many problems will have to be overcome and many basic requirements met.
It is possible that the surface facilities could be quite extensive.
Safe access to the underground workings must be provided.  In addition,
the underground facilities must be adequate to handle the type and
                                   146

volume of waste stored.   Irrespective of what type of mine is selected,
they will all have  several requirements in common.  Most of the surface
handling facilities for hazardous waste will be the same, as will be the
facilities for transporting the hazardous waste from the surface to
underground, and once underground, to its final resting place.  The more
important necessary facilities that would be common to all types of stor-
age sites are listed below.

Subsurface Facilities Required

1.   Unloading the  loading equipment to handle the waste as it is re-
     ceived.  This  equipment must be capable of handling the container
     sizes and waste volumes anticipated.
2.   Possible surface sorting, processing, repackaging, and storage faci-
     lities would be required.  It may be more economical to ship some
     wastes in large bulk tanks and then, once at the storage site, re-
     package them permanently im smaller sealed containers.
3.   Decontamination facilities for men and equipment in case of a
     spill.
4.   Mine ventilation facilities consisting of large surface installed
     fans.
5.   Filters to clean the ventilation air as it is exhausted from the
     mine if necessary.
6.   First aid station.
7.   Standby electric generators in case of a power failure.
8.   Continuous environmental monitoring system.

Facilities Required For Underground Access

1.   Vertical or inclined shaft.  The shaft configuration can be either
     circular, oval, eliptical, or rectangular.   The circular shaft is
     the strongest  configuration and is preferred if the shaft is to be
     sunk through heavy ground and/or it is to be concrete lined.  Fig-
     ure 23 illustrates various shaft configurations which are possible.
2.   Under certain  conditions it may be preferable to gain access to the
     mine via an inclined slope.  The slope could be either a straight
     ramp or a spiral ramp and driven on a shallow grade so that it could
     be negotiated  by rubber tired vehicles.   An inclined slope might be
     suitable for entry into a mine located close to the surface.  An
     advantage would be that waste containers would be transported by the
     same conveyance between the surface and underground storage cell.
     This would eliminate multiple handling.
3.   A minimum of two separate shafts or entries  are required to conform
     with applicable USBM safety regulations and  provide adequate venti-
     lation to the  underground workings.
4.   It is possible that  in some instances, access to the mine could be
     through a tunnel driven into the side of a hill.  In this case,
     waste could be hauled into the mine using a  train or wheeled
     vehicles
5.   If a vertical  or near vertical shaft is used it must be designed to
                                   147

     handle the anticipated waste volumes and container sizes.   The
     headframe and hoist must be designed to lower heavy loads.   This
     could require specially designed hoist brakes and controls  as con-
     ventional hoists are designed to lift rather than lower heavy loads.
6.   The shaft conveyance or cage must be designed to handle special
     shaped waste containers and heavy loads.
7.   The shaft conveyance must also be designed to safely transport
     men and heavy equipment into and out of the mine.
8.   An emergency hoist and man cage should be provided so that  men
     could be removed from the mine or shaft in case the main hoist
     failed.  It should be connected to an emergency power supply.

Basic Underground Facilities And Equipment Required
For A Hazardous Waste Storage Operation

1.   Heavy equipment to unload, haul, and place the hazardous waste stor-
     age containers in their isolated storage cells.  This equipment
     should be rubber tired for increased flexibility and maneuverability
     and especially designed to pick up, move, and place the storage con-
     tainers .
2.   A decontamination station of men and equipment must be provided in
     case of a spill of hazardous waste.  Provision must be made to dis-
     pose of any cleanup waste products.
3.   An air quality monitoring system must be installed in the return
     air passages.  It should be possible to remotely monitor the under-
     ground environment to determine if any waste product is escaping
     from the facility.  The remote monitoring systems should have built-
     in alarms to both visually and audibly alert underground and surface
     personnel.
4.   A rock stability monitoring system should be provided in order to
     verify the long-term stability of the underground structures.  This
     monitoring system could consist of rock extensometers, both manual
     and readout types, and single and multiple position.  The extenso-
     meters should be installed in critical areas to measure roof sag,
     floor heave, and closure between pillars and between the roof and
     floor.  If required, the rock mechanics instrumentation could be
     monitored remotely at a surface station.
5    A fully equipped first aid station, manned at all times by fully
     qualified personnel, will be required underground.
6.   Ventilation booster fans may be required underground; depending on
     the size and complexity of the facility.  The facility must be de-
     signed  so that men are always working in fresh air.  The storage
     cells containing waste must be isolated to prevent personnel ex-
     posure  "air passing through them.  It will probably be necessary
     to install some stoppings, or barriers, In order  to control  the
     direction of the ventilation air.  A considerable number of  stop-
     pings would probably have  to be installed in an  existing mine.
1   In underground  repair shop must be provided  for  maintaining  heavy
     tquipmenfthat  cannot be  easily returned to  the  surface.  An over-
     head crane should be included.
                                   149

-------
 8.  Maintenance equipment will be required underground.  At times it
     will be necessary to clean up loose rock from falls, install ad-
     ditional rock bolts, and grade the roadways.
 9.  If any water is entering the mine it must be collected and pumped
     to the surface.  If the water becomes contaminated with waste pro-
     ducts, it will be necessary to provide handling and treatment
     facilities.
10.  Fire fighting equipment must be provided underground in strategic
     locations.   It must be of adequate size to handle any possible fire
     that might occur.
11.  Adequate bulkheads to separate the intake shaft from the return air
     shaft must be provided.
EVALUATION OF EXISTING AND NEW MINES
AS STORAGE SITES

There are three categories of mines that can be considered for hazardous
industrial waste storage.  These are:  active existing mines, inactive
existing mines, and new mines designed specifically for hazardous waste
storage.  Due to the continuing production of these wastes, the ideal
solution for emplacement of hazardous waste in mines is to obtain a
portion of an operating mine because an operating mine is continually
creating more space.  This concept, however, will require public accept-
ance and industry concurrence.  A generalization of an existing room
and pillar mine is illustrated in Figure 24.  This Figure shows several
of the many room and pillar layouts that now exist.  Less desirable solu-
tions are the use of inactive mines or creating new mines.  Listed below
are some of the more important advantages and disadvantages of existing,
inactive, and new mines as storage sites.

Existing Mines As Waste Storage Sites

Advantages—

 1.  The space is already available.  In some cases, only minor amounts
     of underground cleanup and rock stabilization will be required.
 2.  New storage space is continually being developed for as long as the
     mine is in operation.
 3.  This type of storage should be less expensive than utilizing either
     an inactive mine or a new mine.
 4.  There would be a labor pool experienced in mining operations in the
     area.

D isadvantages—

 1.  The waste storage area must be isolated from the working section of
     the mine by constructing concrete bulkheads.  This would prevent
     possible contamination of the mine and the product being mined.
     Bulkhead construction costs could be quite large depending on the
                                   150

     number of bulkheads required and their design requirements.
 2.  The long-term stability of the section already mined may not be
     good.  This would be due to a high extraction ratio and desire to
     maximize productivity, and could result in extensive remedial
     ground support which may not be adequate over a long period.
 3.  The layout of the section already excavated may be far from ideal
     from a hazardous waste storage standpoint.  This would result in
     extensive new mining and/or loss of storage volume.
 4.  It would probably be necessary to sink new shafts.  It may not be
     possible to do this in the most ideal location due to the require-
     ment for leaving a substantial pillar around the shaft.

Inactive Mines As Waste Storage Sites

Advantages—

 1.  Would not interfere with the operations of an active mine.
 2.  Construction of bulkheads necessary to separate the active mining
     operations from the storage area would not be required.
 3.  It might be possible to use the existing access shafts.  If so,
     this could result in a substantial reduction in total costs for
     converting the mine to waste storage.
 4.  The waste storage operation would not conflict in any way with ac-
     tive mining operations.
 5.  The inactive mine, if sufficiently large and located in the right
     area, could accommodate a particular hazardous waste at its current
     rate of production for a very long time.

Disadvantages—

 1.  A considerable amount of cleanup and repair of the inactive mine
     may be required.
 2.  The mine may not have enough usable space to contain the volume of
     hazardous waste anticipated to be generated over a long period of
     time.
 3.  An older, inactive mine may be less stable due to high extraction
     ratios used while mining.
 4.  The mine could be partly or completely flooded with water, thus re-
     quiring expensive dewatering.
 5.  Original power and railroad facilities may have been removed from
     the site.
 6.  Engineering data such as detailed mine plans and maps may have been
     lost.  This could result in an extensive remapping of the mine.

New Mines As Storage Sites

New mines as sites for hazardous waste storage can be broken down into
two basic categories:

     1.   The mining of an economical mineral commodity occurring con-
                                   152

-------
           currently with  the storage of hazardous waste.  An agreement
           is made with  a  mining company whereby it develops a new mine
           in an  area  suitable for waste storage.  The intent is that a
           mineral commodity, such as salt or potash, could be mined
           profitably  while, at the same time, space for hazardous waste
           storage is  being created.  The mine would be developed in such
           a manner as to  optimize the waste storage facility configura-
           tion.
     2.    Storage space is mined in waste rock having little or no econo-
           mic value.  The waste rock may or may not be sold as fill ma-
           terial, etc.  An example of this type of facility would be one
           mined  in shale, limestone, or granite.

Figure 25  illustrates one concept for a new mine that could be developed
as a storage facility.  First it is necessary to completely mine out one
block or a quarter of the first area involved.  Then, while the mining
of the second block takes place, hazardous wastes can be stored in the
block already excavated.  Once the original 4-block storage facility has
been completed,  a second  4-block storage facility could be constructed
adjacent to the  first,  and so on.

Advantages—

1.   The mine can be  designed specifically for the storage of hazardous
     waste.
2.   The mine could be  designed to be as stable as necessary in order to
     provide for very long-term storage.
3.   There would be essentially no limit to the volume of storage space
     that  could be developed.
4.   There would be considerable flexibility in locating the hazardous
     waste storage facility.  It could be located in a central location
     most  favorable to  the source of waste provided a suitable rock for-
     mation could be  located.

Disadvantages—

The overall mining costs  would probably be greater than those incurred
by using an existing, operating mine.  In the case of a mine producing
a profitable mineral  commodity, more of it would have to be left in the
ground due to a  lower extraction ratio.  If mining space only with no
chance to  sell the material mined, costs will be obviously higher and,
therefore, the storage  costs will be greater.
OPERATION OF A FACILITY

The operation of the underground storage facility will require close con-
trol and monitoring of all phases of waste handling from the time the
waste is received until it is safely stored underground.  Strict atten-
tion must be given to personnel and environmental safety.   It will be
                                    153

necessary  to  provide for the  remote and continuous monitoring of all
critical systems  both above and below ground.

Manpower Requirements

In order to achieve  these goals, a staff of adequately trained people
will be required.  The staff  will probably be somewhat heavy in tech-
nical and  supervisory oriented personnel.  An attempt to quantify the
various labor classifications has been made.  It must be realized,
however, that these  recommended manpower requirements could vary con-
siderably  depending  on such factors as the size of the facility, final
facility design,  facility location, type of waste to be stored,  local
union regulations, etc.

It is anticipated  that the site manager would include among his  staff
personnel, a  health  and  safety specialist having at lease one assistant
and also an instrument technician to help install and service the remote
monitoring equipment.   This department could also be responsible for
monitoring the rock  mechanics instrumentation, and would monitor and
maintain the  mine  ventilation system.  There would also be an office
staff who  would be responsible for inventory control.  Reporting to the
manager, a facility  superintendent would supervise the facility  security
force, the storage foreman, the preparation and cleanup foreman, and
the maintenance foreman.

The storage foreman  would be  in charge of those personnel directly in-
volved in  handling the waste  from its arrival at the site until  it is
safely in  its final  resting place underground.  He would be in charge of
the material  handling specialists who unload the waste when it arrives,
transport  it  to the  shaft, incline slope or tunnel and then unload it
underground.   He would also supervise the hoistman, the shaftman (top
lander), the  surface and underground transporter operators, and  the
underground storage  specialists who oversee waste placement in the
correct storage cells  underground.

The preparation and  cleanup foreman would be in charge of the prep-
aration and cleanup  crew whose duties would include:

     1.    Cleaning up  the storage area and preparing it for waste.
     2.    Cleaning up  falls of rock from the roof and ribs.
     3.    Stabilizing  the roof and pillars by installing rockbolts, steel
           mesh, etc.
     4.    Installing ventilation stoppings (bulkheads).
     5.    Cleaning up  spills  of toxic waste.

The maintenance foreman  would be responsible for the maintenance crew
whose duties  would include grading the underground roadways and  main-
taining the underground  and surface equipment and facilities.
                                   155

-------
Waste Handling Procedure

The overall operation of the storage facility must be well planned and
coordinated.  The more important operations of a hypothetical hazardous
waste storage facility is described in order to point out key operations.

The waste material, as received at the storage site, may be in a storage
container and a form suitable for final storage.  On the other hand, it
may be more economical to ship the waste in large, bulk tank cars to
the storage site where it would then be transferred to smaller containers
for permanent underground storage.  Economics or other conditions may
also dictate that some of the waste products be reprocessed at the stor-
age site prior to being permanently containerized and stored.  These are
variables that would have to be considered in the final design of a haz-
ardous waste storage facility.

Once the waste has been received at the site, careful inventory controls
must be maintained at all times.  This is necessary in order to keep
close check on the waste reprocessing and recontainerizing, if any,
and to verify that each given waste product is stored in the proper
storage cell underground.  Figure 26 is a flow diagram which illustrates
the possible waste handling steps.  The health and safety staff would
monitor the waste handling processes from the time the waste arrives
at the site until it is safely stored underground.

The permanent storage containers should be as large as is feasible and
economical to handle above and below ground.  The maximum container size
will be largely controlled by the size of the access shaft, inclined
slope or tunnel, capacity of the equipment used to transport the waste
underground, and the size of the underground excavation.  More than
likely it will be advantageous to design and build special transporters
for moving the storage containers on the surface and underground.

If access to the underground workings is through an inclined ramp or
horizontal tunnel, it would be possible to use a rubber tired trans-
porter to carry the waste containers from the surface directly to its
storage cell underground.  In the case of a tunnel, a train could also
be used to transport the waste underground.  If access to the mine is
through a vertical shaft, the headframe, hoist, and shaft conveyance
must be designed to safely handle the weight and configuration of the
waste containers.  The braking system on the hoist must be designed to
lower heavy loads.  Normally a hoist is designed to lift heavy loads.
If men are to ride in the shaft for access to the underground workings,
the shaft conveyance (man cage) must be equipped with a safety dog
mechanism.  The safety dogs are designed to stop the man cage in the
shaft should the connection between the cage and the hoist break.

If the waste is lowered down a vertical shaft, provision must be made
to transfer the containers from the shaft conveyance to the underground
transporter.  It will be necessary to install a monorail having an
                                   156

electric hoist in the shaft station to handle heavy equipment and sup-
plies, and possibly waste containers.

Once the waste containers are unloaded at the underground shaft station,
they can be hauled by a rubber tired transporter to their respective
storage cells.  Throughout this operation, careful inventory control
is necessary in order to ascertain that the waste containers are handled
and stored properly.

Preparation Of Storage Cells
For Permanent Waste Retention

Before the waste can be placed in a storage cell underground, the area
must first be prepared to permanently receive the waste.  This would be
the responsibility of the preparation and cleanup crew.  The crew would
repair and mark roadways into the area and bar down any loose rock from
the roof and the pillar ribs.  If required, the roof and ribs would be
stabilized by installing rock bolts, steel mesh, shotcrete, concrete,
or some other form of permanent rock support.

The preparation and cleanup crew would also be responsible for installing
both temporary and permanent ventilation stoppings (bulkheads).  These
are necessary in order to direct sufficient volumes of ventilation air
into the working areas of the mine.  The location of the temporary
stoppings would have to be changed as working conditions warranted it.
This crew would also install the required ventilation booster fans and
ventilation ducts underground.

Should a spill of waste occur, the preparation and cleanup crew would
clean up and decontaminate the area and equipment.  Therefore, it will
be necessary to construct a decontamination room underground where men,
equipment, and materials could be decontaminated.

Health And Safety Environmental Monitoring

It will be the responsibility of the health and safety staff to see that
the health and safety of the work force and people in the surrounding
area is secure, and that the environment is protected from any toxic
effects of hazardous wastes.  This will require setting up and maintain-
ing an adequate safety program that would be mandatory for all employees
to attend.  It would require sensitive sensing devices be installed on
the surface and underground that could be remotely controlled and would
monitor the air and water for toxic substances.  These sensing instru-
ments should be designed to record the data being measured as well as
sounding an audible and visual warning signal when safe limits have been
exceeded.

Rock mechanics instrumentation should also be installed in all critical
areas underground.  This could be in the form of single and multiple
position extensometers, both manual and remote readout types, and devices
                                    158

-------
for measuring  the  rate  of  closure between the roof and floor and between
adjacent pillars.  More sophisticated rock mechanics instrumentation and
measurements would be utilized if necessary.

The health  and safety staff would also have to be prepared to repair
and replace, if necessary, the health and safety monitoring instrumenta-
tion.  It would also be the responsibility of the health and safety staff
to train and maintain a mine rescue crew.  This crew would be on call at
all times in case  of an underground disaster such as a fire, explosion,
cave-in, etc.  and  could include mine workers.

In some instances  it might be necessary to drill vertical wells around
the storage area for verifying that toxic substances were not escaping
from the storage facility  and contaminating the ground water supply.  The
health and  safety  staff would be responsible for monitoring these wells.

Maintenance Of The Storage Facilities

A maintenance  staff will be required to service equipment.  This will re-
quire maintenance  shops to be constructed both on the surface and under-
ground.  The underground shop would service that equipment too large to
be easily transported to the surface for repairs.  The underground shop
must be large  encough to service the waste container transporter.  An
overhead crane will be  required in the underground shop to handle heavy
loads.

The maintenance staff would maintain all of the surface equipment and
facilities.  This  would include the hoists, headframes, electric gen-
erator sets, compressors, surface container transporter,  and all other
vehicles and equipment.  They would also be responsible for maintaining
the surface installed ventilation fans and associated equipment.  In
addition, the  maintenance staff would be responsible for  maintaining all
access roads on the surface and underground.

Site Security

A site security staff would be required in order to control access to
the storage site,  both  during working hours and when the  facility is
closed.  Whenever  a site is closed, for instance during a weekend or
at night, the  security  staff would also water the remote  monitoring
health and  safety  equipment.   If an alarm was sounded,  the site super-
intendent or site  manager could be alerted and the necessary remedial
action commenced.
SUMMARY

There are several factors which must be considered in the design of a
hazardous waste storage facility.  These factors consist of:
                                   159

-------
     1.   Public, political, and owner acceptance of the need
     2.   Geologically secure site
     3.   Facility design
     4.   Operating requirements including safety

Each of these factors have been examined and, in general, acceptable
solutions can be found for any known problems which may occur.

                                SECTION  10

                             PROOF-OF-CONCEPT
In each  section of this  report,  there are stated or inferred conclusions
which were  developed during  the  course of the investigation.  The objec-
tive of  proof-of-concept is  to organize and present these conclusions
and results,  within the  framework of the established criteria and defi-
nitions,  to either prove or  disprove the technical feasibility of stor-
ing hazardous industrial wastes  in mines.  A proof-of-concept approach
was chosen  as the best alternative to a case history study which could
not be performed because no  underground storage facilities of this type
were found  to exist in the United States.
BACKGROUND

The data which  provide  the basis for proof-of-concept are the results of
several primary and  secondary investigations into salient aspects of the
underground storage  problem.  The primary research effort was directed
toward an understanding of the basic technical questions and included
geological, chemical, and geochemical investigations.

The geological  investigation consisted of a physical characterization of
mine areas, including the lithologic, structural, hydrologic, and seismic
environments.   Special  emphasis was placed on those aspects considered
most critical to long-term isolation of the stored wastes.

The chemical study consisted of identifying the wastes,  analyzing the
chemical behavior of each waste compound., determining treatment pro-
cedures to decrease  the hazardous properties of each waste, screening
and classifying the wastes as to hazard potential and chemical compat-
ibility in both pure and treated forms, classifying the  wastes on the
basis of acceptability  underground, and finally determining the present
and future volume of each hazardous waste.

The geochemical study synthesized the results of the geological and chem-
ical investigations.  The seven chosen lithologies, based on mining
activity, physical occurrence, minability, and limiting  and/or beneficial
reactivity, were compared chemically with the waste compounds.  The com-
                                   161

-------
patibility of each waste with each lithology was determined using a
"worst-case" analysis in which the storable wastes were assumed to be in
contact with host rocks under both wet and dry conditions.  The result-
ing reactions would not be possible unless the waste containers were
ruptured by some catastrophic event such as a sudden mine failure, fire,
or flooding.  The possibility of such an occurrence is extremely remote
when all the prestorage criteria are met; however, this approach was
taken to insure that every conceivable interaction which might influence
waste isolation would be appraised.

The secondary studies deal with other pertinent aspects of underground
waste storage which are important to an overall feasibility appraisal,
but are not essential from a strictly technical standpoint.  Included
was a state-of-the-art review of detection, monitoring, and control
technology; an assessment of present and future regulations controlling
underground space; and the development of a conceptual model to illu-
strate the operation of a mined storage facility.

The geological investigation concluded by recommending detailed, site-
specific studies of mines prior to making final recommendations of ex-
isting underground space.  Within the scope .of this study it was not
possible to evaluate mines as rigorously as required; however, AEC spon-
sored investigations of the abandoned Carey salt mine at Lyons, Kansas
for possible use as a radioactive waste repository, provide the types of
detailed information required to make a credible proof-of-concept analy-
sis.
PREVIOUS RESEARCH - LYONS MINE

The inactive salt mine at Lyons, Kansas was worked between 1890 and 1948.
The salt was excavated from the Hutchinson member of the Wellington For-
mation (Permian age) from a depth of 310 meters (1,020 ft).  Room and
pillar mining methods were employed with openings ranging between 2.7 and
4.7 meters (9 to 14 ft) in height.  The total volume of mined space is
approximately 1,019.520 cubic meters (36,000,000 cubic ft), however, the
utility of all the space is uncertain.

The mine area excavated prior to 1940 is described as partly deteriorated
as evidenced by common floor heaves and roof falls.  This area would un-
doubtedly require an extensive rehabilitation and clean-up in order to
be made serviceable.  The areas mined after 1940 at a reduced extraction
ratio (75% prior to 1940 vs. 65% after 1940) are described as showing
only a few minor signs of decay, primarily in the floor.  Minor water
leakage down the shaft has existed for many years, but was never of such
magnitude as to affect the mining operation.  The water problem was de-
termined to be correctable by the mine engineers; however, the need to
implement corrective action never developed.

The bedded salt mined at the Carey mine was typically 95% pure halite
with minor impurities of shale, anhydrite, and water (interstitial).  The
                                    162

-------
anhydrite occurs as discreet zones within  the salt mass, while  the
shales  are usually found as  thin  bedded  layers, partings, and flakes
which give a dark horizontal banded  appearance to the massive salt de-
posit.   The Hutchinson salt  unit  is  approximately 67.1 meters (202.5  ft)
thick at the Lyons Mine site and  is  approximately 85 percent salt  and
15 percent interbedded shale and  anhydrite.  The mined interval  is over-
lain by some 48.8 meters (160 ft) of salt, 168 meters (550 ft) of  shale,
4.6 meters (15 ft) of dolomite and 82.3  meters (270 ft) of mostly  uncon-
solidated sand and clay.  Underlying the mined openings is approximately
10.7 meters (35 ft) of salt  and at least 111.2 meters (365 ft) of  shale.

Significant water-bearing zones occur both above and below the salt;
however,  the mined interval  is effectively isolated by the thick se-
quences  of impervious salt and shale.  The conclusions of the AEC  study
indicate that the most probable threat to the hydrologic isolation of
the Lyons mine is by artificial means such as borehole penetration, or
communication with nearby hydraulic  and  conventional mining operations.
All of  these factors can either be controlled, or eliminated as poten-
tial threats to the integrity of  the mine.

The structural stability of  the mined space was studied intensively,
especially in a limited area of the mine excavated specifically for the
radioactive waste study.   Measurements of pillar load at a 75 percent
extraction ratio indicated that these pillars were under approximately
28,270 kilonewtons per square meter  (4,100 psi) while the load at  a 65
percent  extraction ratio was reduced to  about 19,995 kilonewtons per
square meter (2,900 psi)  and resulted in a much more stable opening.
Plastic  deformation (creep),  slumping, heaving, and rates of closure
were measured using 700 gages,  included were 60 to measure convergence,
and 640  to measure strain (extensometers) variously located in the ribs,
floor, and roof.   Many were  intended to assess the effect of heat on the
structures,  since radioactive wastes generate heat as they decay.  At
temperatures below 200°C.  the transient  and permanent displacements were
typically very slow and predictable.   Core samples tested in a laboratory
at room  temperature and atmospheric pressure gave preliminary compressive
strength  values  of about  19,995 kilonewtons per square meter (2,900 psi)
and tensile strengths  of  2,415 kilonewtons per square meter (350 psi).
This resulted in a calculated creep parameter which would allow complete
closure  in three years.   By  reducing the calculated value by a magnitude
of two,  the closure time  increased to approximately 450 years, which
correlated reasonably well with the field data.

The results  of these investigations indicate that the expected life of
those openings mined at the  65  percent extraction ratio is probably in
excess of 400 years,  and  this  lifespan could be readily extended by
periodic  expansion (remining).  A second option would be to remove the
waste containers,  either  for  recycling or storage in new openings,  on a
periodic  basis as  determined by the rate of closure.   It should  be noted,
however,  that  the  rate  of closure is a natural occurrence which  can be
controlled through reduced extraction ratios, structural supports,  or
remining which would insure  long-term retrievability of the stored wastes.

-------
The effect of heat on the salt formation was found to be significant,
especially above 200°C.  Plastic deformation was seen to increase with
increasing heat until a temperature of 250°C. was reached at which time
the interstitial water was explosively liberated.  The 250°C. temperature
was found to be quite constant even under varied conditions, and the
explosive release was typically powerful and destructive.  On the other
hand, salt was also found to be a reasonably good heat sink capable of
diffusing heat at a rate deemed acceptable for radioactive waste dis-
posal.  Due to the special requirements established for the storage of
chemical wastes underground, heat from reactions or fire will not pre-
sent a significant risk potential.

In addition to the studies of the bedded salt deposit, a qualitative
analysis of the overlying shale unit was conducted.  Generally, this
research showed that montmorillonite and other expanding clays (smectite
group) decreased with depth, while mixed-layer clays and chamosite which
are less expandable increased.  These shale occurrences are significant
in assessing potential waste migration from a salt opening.  Hydrologic
studies to determine the migration potential of contaminants carried in
ground water, confirmed that shale provides an excellent barrier to migra-
tion due to its low porosity and impermeability.  Shales with high mont-
morillonite content have good potential for ion exchange, which causes
these shales to trap toxic ions carried in a ground water solution thus
limiting migration.  In addition, expanding clays have the capacity to
adsorb and hold ground water.  It was found, that adsorbed water commonly
assumes a nonliquid state (quasi-crystalline) which acts to make water
movement in confined argillaceous sediments a self-limiting function.

Results

The original conclusion of the AEC-sponsored study was that the Lyons
mine was a favorable site for the long-term storage and isolation of
radioactive wastes.  Subsequent review, however, concluded that several
potential problems associated with nearby mining operations and the
proximity of the mine to several active oil fields having a high poten-
tial for future exploratory drilling were sufficient to warrant addi-
tional site studies in other areas.  In short, the technical feasibility
of storing radioactive waste was established, but the practicality of
using the Lyons site was questionable.
COMPARISON TO WASTE STORAGE CRITERIA

A comparison can be made of the geologic, hydrologic, chemical and
geochemical criteria developed for the safe storage and management of
hazardous industrial wastes underground to the Lyons mine site.  If a
majority of the criteria can be met, it will be shown that it is techni-
cally feasible to store these wastes at this site, and by inference, at
other sites meeting the established criteria.
                                   164

-------
Homogeneous Lithology

The Lyons mine is in a large bedded salt deposit with approximately
95 percent halite in the mined interval.  Primary impurities are argil-
laceous shales occurring as thin bands plus occasional anhydrite.  Though
typical of bedded salt deposits, this homogeneity is rather exceptional
in nature and is rated as excellent for geochemical analysis because both
the number and types of reactions which could occur between the storable
wastes and the salt formation would be much more predictable.

Competent

Various studies of bedded salt have shown that its strength is comparable
to concrete, but with the added advantage of gradual stress release
through plastic deformation.  The ease of mining, plus its relatively
high structural strength makes salt an excellent mining medium.

Dry and Impervious

Salt is essentially impervious to water, and due to its plasticity it
tends to maintain its imperviousness by healing artificial or natural
fractures.  The Lyons mine is dry except for minor shaft leakage that is
correctable.

LowPorosity

Salt, being crystalline, typically has very low porosity which rarely
exceeds a few percent.  At the Lyons mine the porosity is normally less
than three percent with interstitial water filling most existing pores.

Nonfaulted

The Lyons mine has intersected no known fault displacements and for the
most part the whole Permian Salt Basin in Kansas appears to be free of
large scale faulting.

Isolated From Aquifers

The thick salt deposit plus the thick shale units above and below the
salt effectively isolate the mine from known water bearing strata.

Widespread Distribution

The major salt deposit underlies a large portion of central Kansas.

Thick Deposit

The thickness of the Hutchinson salt at Lyons, Kansas is more than ade-
quate for excavation.  It varies locally, but is generally in excess of
60 meters (200 ft).
                                   165

-------
Low Angle Dip

The inclination of the bedded salt is uniform, and less than 3 degrees
from horizontal.

Dissolution (Alteration)

Dissolution of the salt front, some 58 kilometers (36 miles) east of the
Lyons mine, appears to be progressing west at a rate of 9.7 km/million
years (6 miles per million years).  At this rate, the suitability of
the Lyons site as a storage facility would not be adversely affected.

Low Seismicity

Historic seismicity is rare and of very low magnitude.  Very long tec-
tonic stability is evident.

Slow Surface Erosion

Down cutting by surface streams is generally slow and it is expected that
several million years will be required for them to reach the mine at
present rates of erosion.

Glacial Advance

A study of the consequences of future glaciation indicates that the sta-
bility of the mine should not be effected.

Ocean Inundation

Should present polar ice caps melt, the subsequent rise of ocean levels
would not reach the Lyons, Kansas area.

Low Surface Relief

Kansas is noted for its extremely low relief and the Lyons area is very
flat.

Year-Round Access

Except for brief unusually extreme meteorologic conditions, year-round
access is possible.

Low Economic Value

Salt, due to extensive occurrences, is a high-volume commodity not sub-
ject to sharp economic changes.
                                   166

-------
Mine Depth Less Than 915 Meters  (3,000 ft)

The inactive Carey Mine at Lyons was mined at 310.9 meters  (1,020 ft)
which provides optimum conditions for both access and isolation.

Room and Pillar Design

Various room and pillar combinations were used at the Lyons mine and
all are believed adaptable to fit storage configurations.

Single Level

The mine is single level, ranging from 2.7 to 4.3 meters (9 to 14 ft)
in height with up to 12.2-meter  (40 ft) wide openings thus allowing
easy access and storage.

Large Volume

Approximately 1,019,520 cubic meters (36,000,000 cubic ft) of salt has
been extracted from the Carey mine.  In addition, future reserves totall-
ing 50 percent of the previously mined volume is lease held.  The esti-
mated waste volume in the WNC region (IV) for the year 1975 is approxi-
mately 29,184 cubic meters (1,225,187 cubic ft) or 3.4 percent of the
total mined space.

Two Shafts

The Lyons mine was originally a single shaft operation,  however, a small
access shaft was added for the emplacement of radioactive waste canisters,
It is probable that a second main shaft would be needed to meet present
federal mine safety standards.

Structurally Stable

The pre-1940 mining area is characterized as having undergone moderate
deterioration such as heaving floors,  sagging roof,  etc.  Deterioration
is probably correctable by limited remining, clean-up, and stabiliza-
tion where required.  The post-1940 mine area is described as stable
and in generally good condition.

Operating

The Lyons mine has been inactive since 1948, but the surface facilities
are overseen by a caretaker.   The mine was partly reconditioned during
the 1960Ts for the AEC site investigations.   It is expected that the
mine could be made operable with minimum difficulty.

Accessible to Transportation

The site is convenient to both rail and highway transportation.  Large
                                   167

-------
wheeled vehicles have been used as transporters underground.

Nonreactive to Wastes

The pure-form compatibility of chemical wastes to salt concluded that
none of the geochemical interactions would result in either rapid struc-
tural deterioration or increased migration.  The containerization re-
quirement makes all interactions of the wastes and host rock highly un-
likely.


SUMMARY

A comparison of the inactive Carey salt mine at Lyons, Kansas to the
basic technical criteria requisite to safe storage and management of
hazardous industrial wastes underground has shown that this mine could
be utilized as a safe waste repository.  Certain practical and economic
considerations would require additional review prior to making a final
recommendation; however, all of the purely technical considerations have
been met.

The evaluation of the Lyons mine is not intended to be a recommendation
of that site, but is made only to indicate the feasibility of the re-
gional waste storage concept using suitable mines.

The regional relationship of potentially suitable underground mines to
the volume of hazardous industrial wastes is illustrated in Figure 27.
It is clear that every waste region contains at least a few operating
mines in the lithologies of interest.   Several of these mines can be
expected to meet the criteria for hazardous waste storage.

                   RECOMMENDATIONS FOR NEEDED RESEARCH
The recommendations for research presented in this section are intended
as guidelines in establishing effective programs to enable the storage
and management of hazardous waste in underground mines with maximum pro-
tection of the environment.  This discussion describes the information
needed to close existing gaps in technological data and to complete im-
portant studies recommended in this report.   A general estimate of the
funds and time required to complete this research is presented in the
Table at the end of this section.
ECONOMICS

As a result of this study,  the underground storage of hazardous wastes
appears to be technically feasible.   It is therefore recommended that a
complete economic evaluation of the  concept be conducted.   Such a study
should include the probable cost of:

     1.   The acquisition of land and the construction and maintenance
          of surface facilities including docks,  warehouses, labs,
          offices, housing, outbuildings, etc.
     2.   The acquisition of a mine  and the construction and maintenance
          of underground facilities  including shafts, mine rehabilita-
          tion, bulkheads,  ventilation, etc.
     3.   The acquisition and maintenance of equipment including fork-
          lifts, hoists, hoppers, conveyors, pumps, piping, fans,
          miscellaneous machinery, electronics, etc.
     4.   Containers and containerization facilities.
     5.   Treatment and treatment facilities including chemicals, water,
          equipment, etc.
     6.   Miscellaneous items such as commodities, protective clothing
          and equipment, decontamination facilities, etc.
     7.   The acquisition,  operation, and maintenance of detection,
          monitoring, and control equipment.
     8.   Fuel and power requirements.
     9.   Payroll including labor, inventory, medical, professional,
          technical, administrative,  clerical, security, quality con-
          trol, etc.
                                  170

-------
      10.  Personnel  training  programs  in  safety  and  operation.
      11.  Annual  operation.
      12.  Future  expansion.
      13.  Public  relations and  education.
GEOLOGICAL  CHARACTERIZATION

To fulfill  the  contract  directive, a listing of existing underground
mines in  lithologies  favorable  for waste storage was compiled.  This
list includes available  information as to name, locations, owners, oper-
ators, design,  and  other pertinent data.  Following an intensive search
of existing literature,  it was  found that much of the required informa-
tion was  not available for working mines.  In addition, such information
was almost  nonexistent for nonworking mines.  Without a comprehensive
data base from  which  to  locate  mines favorable for waste storage, the
further study and evaluation of mines with respect to their suitability
as potential sites  is severely  limited.  It is, therefore, recommended
that a list of  working and nonworking mines be compiled including the
following information:

     1.   Name
     2.   Location
     3.   Owner
     4.   Operator
     5.   Mining Methods
     6.   Conditions - number of shafts and levels, depth, age, water
          conditions, general state of repair,  physical dimensions of
          workings.
     7.   Geology - description of deposit,  dip,  visible jointing,  fault-
          ing,  or fracturing.
     8.   Principal minerals mined and their current and expected econom-
          ic value or importance.
     9.   Annual production and extraction ratios.
    10.   Estimated volume.

Once a study of this general type has been completed,  it will be possible
to locate favorable potential sites and perform a detailed geological
evaluation  of their suitability for waste storage.  An assessment of each
mine is necessary due to the unique nature of each mined opening.   Such
a study could be conducted in conjunction with  the more general study
outlined above.   It is recommended that the  detailed investigation in-
clude an analysis of the following:

     1.   Lithology - composition, strength,  chemical properties,  alter-
          ation, size of-deposit.
     2.   Structure - seismic probability,  faults, fractures,  joints,
          stratification, stability.
     3.   Hydrology - water conditions in mine,  location of aquifers in
          proximity to mine,  location of artesian water and other sur-
                                   171

-------
          face water,  drainage patterns,  rate of salt dissolution.
     A.    Geomorphology - stability and relief of surface.
     5.    Complete description of underground workings including dimen-
          sions of openings and supports.   The location of  any abandoned
          or working drill holes, mines,  industry,  towns, houses, farms,
          ranches, etc.  in proximity to the site should also be deter-
          mined .
     6.    A general evaluation of the environmental suitability for
          waste storage.

Once the most favorable mines  have been indicated geographically and
geologically, the final selection of each site should be preceded by an
assessment of mine owner and public attitude towards such a facility and
an environmental impact statement depicting the potential effects on the
environment resulting from the operation of a facility in an area.

The data compiled from these recommended studies would allow the selec-
tion of  sites having the least probability of future environmental or
operational problems.
WASTE CHARACTERIZATION

The purpose of characterizing the wastes was to gain knowledge of their
hazards to the environment and to develop methods of reducing those
hazards to allow their placement underground while ensuring short and
long-term protection of the environment.   As stated previously in this
study, a pure-form method of analysis  was used due to a lack of informa-
tion on waste streams per se.  Since this method of analysis only pro-
vides a limited representation of the  hazards of actual industrial waste
streams, research in this area is recommended.  Such a study should in-
clude the following:

     1.   A complete quantitative analysis of all waste streams contain-
          ing candidate wastes,  including the percentage concentration
          of each constituent and the  physical state of the stream as a
          whole.
     2.   The detailed analysis  of the physical, chemical, and hazardous
          properties of each waste stream.

In attempting to identify the hazards  of waste streams using the pure-
form approach, it was found that some  pertinent information was lacking.
Data concerning the solubilities, densities, boiling points, vapor pres-
sures, flammable or explosive limits in air, volatility, etc. was either
conflicting or nonexistent for many of the candidate wastes.  Since some
industrial waste streams may be  suited to a pure-form analysis, or may
include compounds requiring treatment  in their pure-form, research in
these areas is recommended.  A form similar to that presented in Appendix
B-l of this study, could be used.

As a task of waste characterization, available data on waste volumes was
                                   172

-------
compiled and estimates of the volumes expected by the years 1975, 1980,
and 1985 were made.  In attempting to complete this task, it was found
that significant amounts of information were lacking.  Projection data,
in many cases, were found to be too general for application to a specific
candidate waste.  Much of the information concerning the production and
quantification of the wastes was either conflicting or nonexistent.   In
addition, the pure-form approach complicated matters by prohibiting the
use of general waste stream data when the proportionate concentration
of a candidate waste was unknown.  For these reasons, a detailed study
of the volumes of industrial waste streams is recommended.  Such a study
should include the following information:

     1.   A breakdown of candidate waste production by industry.
     2.   The annual volume of each waste candidate generated by each
          industry.
     3.   The geographic distribution of the wastes showing areas of
          concentration.
     4.   The outlook as to an increase or decrease in waste production.

Since the reduction of the hazards associated with the candidate wastes
is essential for the protection of the environment, treatment procedures
for the wastes were compiled.  These treatment procedures are based upon
the pure-form analysis and may not depict all of the products of treat-
ment which may result from an actual waste stream.  They do however,
represent treatment procedures and products of the most hazardous con-
stituents in waste streams.  Within the scope of this study, it was not
possible to perform tests of these procedures; hence, they are presented
in theory only.  It is recommended that a study be conducted to generate
the following information:

     1.   The development of treatment procedures for the candidate
          wastes whose treatment requires further study (Table 10).
     2.   An evaluation of the compiled treatment procedures for the
          candidate waste streams by the application of appropriate
          chemical engineering principles and tests and amending those
          needing revision.
     3.   An application of the tested methods to actual waste streams
          containing the candidate wastes and amending those needing
          revision.
     A.   A detailed analysis of the physical, chemical,  and hazardous
          properties of the treatment of products.
     5.   The determination of the proper treatment level for storage
          based on a cost/benefit analysis.

It is the understanding of the investigators that many of these recom-
mended studies are presently being conducted under government contract.
However, if the data acquired under these contracts does  not provide all
the information which has been recommended,  the gaps in the technological
information will not be fully closed.   Since this information is essen-
tial to the efficient operation of a waste facility, it is recommended
that these studies be expanded where necessary to provide the recommended
data.
                                   173

-------
Since the use of containers is recommended for the underground storage
of hazardous wastes,  a study should be conducted to determine the proper
type of containerization or encapsulation needed to meet the require-
ments of underground  storage.   An ideal container would have the follow-
ing properties:

     1.   The ability to withstand expected internal and external pres-
          sures .
     2.   The ability to withstand impact loading such as puncture or
          crushing.
     3.   Be of  a size, weight, and shape which would facilitate fabri-
          cation, filling,  handling, and storage.
     4.   Impermeable to liquids or gases.
     5.   Nonflammable.
     6.   Chemically  inert.
     7.   Be of  a material which would lend itself to mass production.
     8.   Be permanently labeled.
     9.   Economical.
GEOCHEMICAL INTERACTION

Within the scope of this study,  it was not possible to investigate be-
yond the first-level chemical interactions of the wastes with each other
and geological formations.   The obvious potential for further chemical
reactions indicates that additional research is needed in this area.
WASTE MIGRATION

Due to the unique physical nature of each mine site, the investigation
of the environmental effects of waste migration at each particular site
was not possible within the scope of this study.  It is recommended that
research be done in this area.   This research should include an assess-
ment of any physical or biological effects on the environment and any
changes in the properties of a waste which may result from waste migra-
tion.
DETECTION, MONITORING, AND CONTROL TECHNOLOGY

It is recommended that research be done to develop existing equipment
into optimum systems to detect, monitor, and control waste migration.
Such systems should be capable of monitoring the air, water, and stabi-
lity in and around a mined opening to provide ample warning of any im-
pending danger.
LEGISLATION

If the concept is accepted, controlling and safety legislation applicable
                                   174

-------
to  the use  of  underground  space  for  the storage of hazardous wastes  will
be  required.
DEMONSTRATION FACILITY

If an economic study supports  the feasibility of the concept, it is
recommended  that  a  demonstration facility should be designed, construct-
ed, and operated  in order  to confirm operating principles and costs.
Such a facility would allow a  more realistic appraisal of the potential
advantages and disadvantages of implementing the concept on a national
scale.
ESTIMATE OF TIME AND FUNDS

A generalized estimate of the time and funds which would be required to
complete these recommendations is presented in Table 18.

                              SECTION  13

                              DEFINITIONS


1.   Acceptable Waste -  Wastes acceptable  for underground storage should
     conform to the following guidelines:
     a.    Nonflammable
     b.    Nonexplosive
     c.    Will not evolve hazardous  gases  when exposed to air, water, or
          heat.
     d.    Containerized
     e.    Unable to be dispersed in  air or water in concentrations ex-
          ceeding the established TLV  for  the material.

2.   Bureau of Census Regions
     a.    NE - New England Region including Connecticut, Maine, Massa-
          chusetts, New  Hampshire, Rhode  Island, and Vermont.
     b.    MA. - Middle Atlantic Region  including New Jersey, New York,
          and Pennsylvania.
     c.    ENC - East North Central Region including Illinois, Indiana,
          Michigan, Ohio, and Wisconsin.
     d.    WNC - West North Central Region including Iowa, Kansas, Minne-
          sota, Missouri, Nebraska,  North Dakota, and South Dakota.
     e.    SA - South Atlantic Region including Delaware, Florida, Geor-
          gia, North Carolina, South Carolina, Virginia, and West Vir-
          ginia.
     f.    ESC - East South Central Region including Alabama, Kentucky,
          Mississippi, and Tennessee.
     g.    WSC - West South Central Region including Arkansas, Louisiana,
          Oklahoma, and Texas.
     h.    M - Mountain Region including Arizona, Colorado, Idaho, Mon-
          tana, New Mexico, Nevada,  Utah,  and Wyoming.
     i.    W - West (Pacific) Region including Alaska, California, Hawaii,
          Oregon, and Washington.

3.   Conventional Mining - Extraction is  accomplished by physically or
     mechanically breaking, loading, and  removing the material.

4.   Environmental Risk - As used in Appendix B-3, Waste Treatment Pro-
     cedures,  this term refers to a toxic waste treatment product which
     is essentially nontoxlc but should not be disposed of in an uncon-
                                   184

-------
      trolled manner.  Such materials are basically nontoxic but might
      create environmental problems if released freely.  Although these
      products are acceptable for underground storage, their placement
      underground may not constitute the best use of available mine
      space if other environmentally acceptable methods are available.

 5.   Hazard Index (H.I.) - The sum of the ratings of individual hazards
      indicating a waste's acceptability for underground storage accord-
      ing to the following criteria:  H.I. = 0-5, containerization only;
      H.I. = 6-9, optional treatment; H.I. = 10-25, mandatory treatment.

 6.   Hazardous Wastes - Waste candidates for underground storage are
      noxious industrial wastes that present special problems in treat-
      ment or handling.  Radioactive and wholly military (D.O.D.) wastes
      are not included.

 7.   Ideal Mine - The following requirements concerning an ideal mine
      for the storage of hazardous wastes are based on experience and
      safety considerations and will be utilized in the screening of
      favorable mines.
      a.  Structurally stable.
      b.  Homogeneous deposit.
      c.  Dry and impervious.
      d.  Nonreactive to waste.
      e.  Flat lying floor or horizontal deposit.
      f.  Room and pillar mining scheme.
      g.  Single level.
      h.  Large volume.
      i.  Not over 915 meters (3,000 feet) deep.
      j.  Accessible to transportation.

 8.   Mine Environment - The elements that occur in and around a mined
      opening which would be subject to contamination.   These elements
      include:
      a.  The surrounding rock (lithology).
      b.  The mine air which takes the form of exhaust.
      c.  The ground water surrounding the mined opening either fresh or
          saline.
      d.  Objects not naturally occurring in a mine such as:   personnel,
          equipment,  and containers.

 9.   Modified Mercalli Intensity Scale - An earthquake rating system
      developed by S.T. Algermissen (NOAA) to indicate relative ground
      motion based on effects observed on people and objects.

10.   Room and Pillar - Mining method whereby large support pillars  and
      level interconnected rooms remain after ore  extraction.

11.   Recommended Provisional Limit - A concept proposed by TRW Systems
      Group which was evaluated and subsequently utilized by the investi-

      gators in this  study.   It  is  a value  indicating  the  concentrations
      of materials  in air  or  water  to which it  is believed the environ-
      ment outside  the physical  boundaries  of processing facilities  could
      be continuously exposed without adverse effects.  In air,  this
      value is  equal  to one-hundredth of  the established TLV.   In water,
      the value is  equal to the  current established  drinking water stan-
      dard or one-hundredth the  lowest reported drinking water study
      level.

12.    Threshold Limit Value (TLV) - Values  set  by the  American Conference
      of Governmental Industrial Hygenists  which indicate  concentrations
      of materials  in air  representing conditions under which  it is  be-
      lieved that nearly all  workers may  be exposed  repeatedly for a
      normal work day over a  working lifetime without  adverse  effect.

13.    Treatment Level - Indicates the points at which  significant change
      in the physical form or Hazard Index  of a waste  occurs during  its
      treatment.

Comments/Description
Filtration  (fiber, paper, activated
charcoal, membranes, etc.).

Fluid flow  through coarse medium de-
posites particulate load.

Submicron and larger - dependent on
type of filter, fluid load, and flow
time.

Limited quantification - poor to no
qualification size-grading.

Very good, with proper maintenance.

Many filtration systems readily avail-
able.

Filtration systems provide excellent
sampling capability and very good
control (cleaning) capability.  It
is necessary to service (clean, re-
place, etc.) the filter media period-
ically for the system to function
well.  Identification of particu-
lates can be made using other tech-
niques .

                        CONTROL/SAMPLING SYSTEMS
Instrument or Technique             Settling (dust jars, adhesives).

Operating Principle                 Gravitational deposition of particu-
                                    lates (usually on a "holding" media
                                    such as liquid or adhesive).

Operating Range                     Particulates commonly greater than
                                    micron size.

Limitations                         Limited quantification, poor quali-
                                    fication.  In a mobile fluid size-
                                    grading is normal.

Reliability                         Excellent, with proper maintenance.

Availability                        Many commercial and "home built"
                                    systems.

Comments/Description                Settling systems provide simple,
                                    cheap, and limited sampling capa-
                                    bility.  Rough quantification is
                                    possible; however, qualification
                                    normally requires other systems.
                                    Problems of separating participates
                                    from "holding" material are inherent
                                    in system.

Comments/Description
Inertial Collectors  (impactors, im-
pingers, cyclones).

Impactors - higher mass particles
lose momentum on contact with de-
flector.  Centrifuges - particulates
spin-out of circular fluid flow.

Generally 0.5-50 micron size - in-
creased effectiveness using multiple
stages.  Dependent on velocity:
increase velocity = decrease particle
size.

Quantifies within range.  Limits
sizing by using multiple stages.

Good - high abrasion of impact sur-
faces common.  Dependent on unit
complexity and maintenance procedure.

Many commercial units of several
designs and efficiencies are avail-
able.

Inertial collectors are good for con-
tinuous sampling/cleaning operations
of particulates in heavy-load fluids.
Problems of efficient recovery and
abrasion are common.

Precipitators

Electrostatic-charged particles in a
strong electric field are attracted
to poles.  Thermal-airborne particles
are driven to cold substrate in a
temperature gradient environment.

All sizes - submicron ranges up to 3
or 4 micron size.

Particles must possess electrical
charge (inherent or induced) small
volume.

High efficiency (up to 98%) good
reliability with maintenance
excellent reliability of perfor-
mance.

Commercially available (several types
& sizes) .

Electrostatic precipitators are high-
ly efficient cleaning/sampling de-
vices up to moderate loads.  In gen-
eral, size, efficiency, and cost rise
together.  Thermal precipitators are
generally slow, low volume separators.

Specific Gas Spectrometer (NASA).

Heliarc combustion of gases pro-
duces unique light emissions.  Com-
ponents of a gas mixture can be
identified using photomultipliers and
spectrometer analysis.

As developed:  detects 02 and H2 in
Argon carrier to less than 5 ppm.

Used to monitor impurities in inert
welding gases.

The technique has proven reliability
as developed.

The technology is available and the
necessary components are commercially
produced.

Although limited as developed, the
technique holds excellent potential
for being expanded to monitor any,
or possibly all components of an
airstream (gaseous elements).  The
addition of photomultipliers re-
sponsive to individual gas emission
lines might make a valuable air-
stream monitor.

 16. ABSTRACT
       This  study assesses the technical feasibility of  storing nonradioactive
  hazardous  wastes in underground mined openings.  The results show that a majority
  of the wastes  considered can be stored underground in  an environmentally acceptable
  manner if  they are properly treated  and containerized.   Various mine environments
  in the United  States are applicable  for such storage;  room and pillar mines in  salt,
  potash, and  gypsum appear to be the  most favorable.  Although the underground
  storage and  management of hazardous  waste is both technically feasible and environ-
  mentally sound, further and more  detailed research, including an economic evaluation,
  is recommended.
