STATEMENT OF BASIS AND PURPOSE

This  Record of  Decision Amendment  presents  the  United  States
Environmental  Protection   Agency's   (EPA's)   selection   of   a
modification to  the  remedial  action for the G.E.  Wiring Devices
Superfund Site (the "Site"), in accordance with  the requirements of
the  Comprehensive   Environmental   Response,   Compensation,  and
Liability Act of 1980, as amended (CERCLA),  42  U.S.C. S9601-9675,
and  to  the extent practicable,  the National  Oil and Hazardous
Substances  Pollution Contingency Plan,  40  CFR  Part 300.   This
Record of Decision Amendment explains the factual and legal basis
for  selecting  the modified  remedy  for  the  Site.    The original
remedial action was  selected  in  the Record  of  Decision issued by
EPA on September 30,  1988.

The attached index (Appendix 1) identifies the  items  that comprise
the Administrative Record upon which the  selection of the remedial
action is based.
ASSESSMENT OF THE SITE

Actual  or  threatened releases  of  hazardous substances  from the
Site,  if  not  addressed  by  implementing  the  response  actions
selected in the September 30, 1988 Record of Decision, as revised
by this Record of Decision Amendment, may present an imminent and
substantial  threat   to   the  public  health,   welfare,   or  the
environment.


DESCRIPTION OF MODIFICATION TO THE SELECTED REMEDY

The  modification  to the selected  remedy  implements the off-site
disposal of all excavated mercury-impacted materials in a Subtitle
C  (hazardous waste) landfill in the mainland United  States without
additional treatment,  in place of the on-site hydrometallurgical
treatment using the G.E.  Mercury Extraction  Process  (GEMEP)  system
and  subsequent backfill.

-------
  The components of the modification to the  selected  remedy consist
  of the following:
o    Elimination

t?eatednmaterial
of
                        the   on-site   hydrometallurgical  treatment
                          includin9  the on-site backfilling of the
 o    Complete excavation of remaining mercury impacted materials,
 including the clean washed coarse materials  (mercury concentration
 below  the residential   remediation  goal  (RG)  of 39  parts per
 million  or  ppm)  that  were  backfilled  in the  West  Field and
 contaminated materials  remaining underneath structures  in three
                                       electrical substation pads,
                                              °f

 o    Placement of  approximately 1,600  tons of clean,  oversized
 material currently in the West Field into Lift  Liners.

 Li-  Trfn?port of the approximately 11,600  tons of  containerized
 material to a permitted RCRA Subtitle  C hazardous  waste landfill
                 e*pected that the specific  landfill  that  will  be
                  located in Pinewood,  South Carolina;  the wastes
 p      f  tran;P°rted via  truck to Ponce,  by  covered barge  to
 Charleston,  and by truck to Pinewood.

revegetation, and to make  it  available  for productive  future use.

All the other components of the original remedy as  selected in the
September  1988  Record  of Decision  are  NOT  affected  by this
modification.  These components are:

o    Limited groundwater monitoring (i.e., for a minimum of three
^!ar!i' u9^Veu    ^  additional  groundwater  investigation  has
established that there is no need for groundwater remediation.

o    Confirmatory  air  monitoring  and   re-sampling  of  soil  in
residential yards.

-------
EXPLANATION OF FUNDAMENTAL CHANGE

The   September   1988   Record  of   Decision  addressed   mercury
contamination  in the  waste-fill area  known as  the West  Field,
including the waste-fill materials, contaminated near-surf ace soils,
and  perched  ground water expected  to  be encountered in  the  West
'Field having mercury concentrations above the health-based cleanup
levels  specified  by  EPA.     Major remedy  components  were  (1)
excavation of wastes from the West Field  and the contaminated near-
surface soils,  (2) on-site hydrometallurgical treatment of materials
containing mercury in excess of 39 ppm,  (3)  on-site backfilling of
the treated materials having mercury levels  less than 39 ppm in the
West Field,  and  (4)  installation of  a two-foot thick  clean  soil
cover over the backfilled area.

The conceptual hydrometallurgical treatment component described in
the  1988  Record of  Decision  differs  from the  specific  GEMEP
hydrometallurgical treatment  system which was ultimately designed
for the Site in two significant ways.

1)   The  1988  Record  of Decision did  not consider  a  physical
separation  treatment  step  that  would remove  both clean,  coarse
material and high concentration metallic debris from the materials
to be treated hydrometallurgically.

2)   The  1988  Record  of Decision envisioned  use  of  a  readily
available leaching agent, such as  cyanide,  hypochlorite or nitric
acid, which  were subsequently determined to be  ineffective based
upon treatability study results.   It also assumed the need for only
one batch of leaching agent.  The GEMEP uses  iodine, which was never
evaluated or even considered as a leaching agent.

During initiation of remedial activities,  excavation of waste-fill,
and implementation of the physical separation treatment step,  G.E.
encountered Site conditions that significantly differed from those
which served as basic assumptions in developing the 1988 Record of
Decision.  These  changed  conditions make the original  remedy less
implementable and more costly than  other  remedial alternatives.

The significant changed conditions  include  a 250  percent increase
in  the waste  volume;  significant  differences   in  the  physical
characteristics  of  the waste (e.g.,  clay  content); and  serious
concerns regarding the inability  to  procure the additional quantity
of   chemical   extraction  agent    (iodine)   needed  to   complete
hydrometallurgical treatment of the  expanded waste volume using the
                                -3-

-------
  GEMEP system.   These variations  and  their impact on the original
  remedy are described as follows:

  Waste Volume  - The  estimated volume  of  contaminated  materials
  excavated to date  has increased from  5,005 tons calculated in the
  1994  Preliminary Design report to 11,700  tons. The estimated volume
  of  contaminated material requiring GEMEP  treatment  has  increased
  from  4,105  tons, calculated in the 1994 Preliminary Design Report
  to  10,000  tons.  The difference between  these two sets of volumes
  represents  the clean coarse materials and  the  high  concentration
  materials  which were disposed  off-site.  The  majority  of  these
  additional wastes consist of fine-grained clay soils, which are not
  conducive to GEMEP  treatment.   Moreover,  the  amount  of soil  to be
  excavated  as part  of the  remedy has more than quadrupled  from
  original estimates.

  The major increase  in waste volume will  cause the GEMEP  treatment
  system, which is based on mass, to run  significantly longer and cost
  significantly more  than anticipated in 1988.  The increased tonnage
  from  the West  Field has  already  contributed to  a  significant
  increase in the duration of the excavation  and  physical  treatment
 components.    Also,  the  available  space  on-site  to  stockpile
 materials awaiting  treatment is limited.

 Waste  Composition - The content of fine soils  (i.e., clay) in  the
 materials from  the  West Field is much greater than anticipated in
 the  remedial design,  which assumed that 34 percent of  the  materials
 would  consist of fines.  Recent  grain-size analyses indicated that
 the  wastes actually consist of  85 percent fines.   The tests also
 showed that about 63 percent of the  material is  clay-sized.

 These  changes in waste composition will cause a significant increase
 in  the  amount  of  clay  materials requiring treatment,  which is
 expected to  result  in substantial materials  handling difficulties
 The new waste characteristics already have caused the excavation  and
 physical  treatment   components to far exceed  the original  time
 schedule.   For  example,  the physical  separation  process took 34
 weeks  to  complete, in  comparison to the projected 4-week  schedule
 High clay content coupled with increased volume caused plugging  and
 fouling  of the  physical separation treatment  equipment.   Similar
 setbacks  to  the  GEMEP  time frame are now expected due to materials
 handling  and dewatering difficulties.

 Iodine Usaqe  -   The  GEMEP  treatment  system uses  iodine,  a limited
 commodity on the world market, as an extraction agent.  Laboratory
 tests indicated a conservative consumption rate of iodine equal to
 1 percent of the treated soil/waste.   Based on the projected waste
volume at that time, G.E. procured 40 tons of iodine.   At  present
                                -4-

-------
assuming the 1 percent consumption rate, at least 100 tons of iodine
will be needed by GEMEP because of the 250 percent increase in waste
volume.   The additional 60 tons of  iodine now required for   the
GEMEP system will be difficult, time consuming and costly to obtain,
given that the majority of  the global  iodine production is sold out
for the next two years.

Two major  operational  factors,  the significant increase in waste
volume and the uncertainties associated with the iodine consumption
rate in a full-scale GEMEP  treatment system, further exacerbate the
situation.  G.E. would need to procure the additional  iodine prior
to system  start-up to provide  an  adequate supply for  continuous
operation.

Based on iodine  losses of 1 percent and the  treatment of 10,000 tons
of material,  the estimated total  cost of the GEMEP remedy is now
estimated at  $8.8 million, assuming  the treatment  system runs 'for
52 weeks.    Four other scenarios  were developed  in the  Focused
Feasibility  Study,  illustrating the  cost  impact associated  with
higher  and lower treatment  rates,  higher  iodine  losses,   and  an
increase in the total quantity of material'.  These  estimated total
costs ranged from $7.9 to $11.4 million.

In light of  these  factors,  EPA proposed to eliminate the  on-site
treatment  component of  the original  remedy in favor of off-site
disposal in a permitted-RCRA Subtitle C hazardous  waste landfill.
EPA is NOT proposing to  change the mercury cleanup level it  adopted
for  the  Site  in  1993,  which  remains  at 39  ppm.    The  only
modification  to the  remedy  involves  the off-site  disposal  of
materials greater than 39 ppm mercury,  including the three areas of
waste deposition yet to be excavated.   In  comparison  to the GEMEP
treatment  approach  described  above,  off-site  disposal  has  an
estimated cost of less than $3.5 million.  Thus, the modified remedy
will also result in a significant cost savings.
DECLARATION OF STATUTORY DETERMINATIONS

The original remedy,  as revised by the selected modification, meets
the requirements for remedial actions set forth in CERCLA §121,  42
U.S.C. §9621 in that  it:  (1) is protective of human health and the
environment;  (2)  attains a  level  or standard  of control  of  the
hazardous substances,  pollutants and contaminants,  which at least
attains  the  legally   applicable  or   relevant  and  appropriate
requirements under federal and state laws;  (3)  is cost-effective;
(4)   utilizes   alternative  treatment   (or  resource   recovery)
technologies to the  maximum  extent practicable;  and (5)  satisfies
the  statutory  preference  for  remedies  that  employ treatment  to

                               -5-

-------
reduce  the   toxicity,   mobility,   or  volume  of  the  hazardous
substances,   pollutants   or   contaminants   at  a  site.   Physical
separation treatment, consisting of dry screening, wet soil washing,
and magnetic  separation  of the mercury  contaminated  materials to
remove both clean coarse material and high concentration materials
containing "free" mercury was conducted.

Because the modified remedy will not result in hazardous substances
remaining on-site above health-based levels, the five-year remedial
action review will not apply to this action.

                   RECORD OF DECISION AMENDMENT
                G.E.  Wiring Devices Superfund Site
                     Juana Diaz, Puerto Rico

I.   INTRODUCTION

The G.E. Wiring Devices Site is located in the  south central  part
of the island of Puerto Rico on Calle Carrion Maduro Final  (Carr.
149,  Km.  67)  in  the municipality  of Juana  Diaz.    The Site  is
northeast of Ponce, close  to the intersection of Routes 14 and 149.
See Location Map  (Figure  1).  The General Electric  Company  (G.E.)
operates a wiring devices plant  at the Site,  manufacturing various
residential, institutional, and commercial electrical devices,  such
as night lights, wall outlets, and switches.  The plant covers about
six acres, and includes a 1.1 acre waste-fill area,  referred to as
West Field, that is the source of mercury contamination.   See Site
Map  (Figure 2) .   G.E.  has not  used mercury in its  manufacturing
process at the Juana Diaz plant since 1970.

Several residences are  located  about 400 feet  south of  the  West
Field area. Ground water  in the area is used as a source of potable
water.  A public supply well is located about  1,500 feet west of the
waste-fill area.

From 1957 until 1969, G.E. used the  waste-fill  area  known as West
Field to dispose of defective electrical components, including parts
from silent mercury switches.  Each switch contained a hermetically
sealed,  stainless-steel  button  that  encased  a   ceramic  core
containing elemental  mercury.  At the Site, G.E. broke open buttons
that did  not meet  quality specifications to reclaim the mercury.
G.E. then discarded the steel button shells,  with residual mercury
and  ceramic cores,  in  the  waste-fill  area,  along  with  other
defective switch parts and plastic scraps.

Test pit excavations  indicated that the waste-fill area was roughly
1  to 4 feet  thick and  covered 1.1  acres.   Site  investigations
confirmed that  the mercury is tightly bound to the components in the
waste-fill area and has not migrated or entered the  ground  water.
Based on available data, including sampling and analysis by EPA in
April 1982, the Site was  included  on the National Priorities List
of hazardous sites in December 1982.
                                -7-

-------
  II.  G.E. WIRING DEVICES SUPERFUND SITE                             ^^

  Throughout the mid- to late-1980s, EPA and G.E. conducted numerous
  field  studies to  determine the  extent of  contamination and  to
  evaluate cleanup alternatives.   In 1987, Law Engineering performed
  a remedial investigation/feasibility study (RI/FS) of the West Field
  for G.E.

 After review of the FS, EPA directed the U.S. Bureau of Mines (BOM)
 to evaluate additional treatment technologies that could achieve a
 permanent remedy.  BOM evaluated hydrometallurgical treatment, using
 a variety of  chemical  reagents, such as acid and chlorine,  to leach
 mercury from  a generic host material.  BOM concluded that additional
 studies of leaching using  Site-specific' waste materials would  be
 necessary.

 In September 1988,  based on an Addendum FS, EPA  selected a  remedy
 and issued the ROD  for the Site.  This remedy called for excavation
 of wastes from West Field and the  contaminated  near-surface  soils
•on-site hydrometallurgical  treatment of  the materials,  backfilling
 of the excavated area with  treated materials,  and placement of a
 two-foot thick  cover  of clean soils over the  backfilled  area
 Hydrometallurgical   treatment   involves  mixing   on-site   waste
 containing mercury  with  a  leaching  agent  to create  a solution
 containing the mercury.   The solution is filtered,  and  the mercury
 is then removed by  precipitation or  cementation.   The mercury can
 then be recovered.

 EPA revised the Baseline Risk Assessment  for the Site in 1993.  The
 Risk Assessment calculated a residential  remediation goal (RG) of
 39  parts per  million (ppm) for mercury levels in soil at the  Site
 The residential RG  is based on  a residential  exposure scenario
 involving ingestion of  soil  and waste.  This meant  that all material
 with mercury concentrations  above the residential RG of  39 ppm would
 be  removed, and that treated materials returned to the West Field
 would be  required to have mercury concentrations  of  less  than 39
ppm.  The ROD also included a groundwater component that consisted
of  the  installation of monitoring wells and groundwater sampling.

 In late 1988,  G.E. took over the treatability studies from the BOM
with EPA oversight.  From 1994  to  1997,  under EPA oversight,  G.E!
patented  a  mercury  removal process  called  the  G.E.   Mercury
Extraction Process  (GEMEP)  treatment  system.   GEMEP uses  a  water
solution of iodine  and iodide to extract mercury  from  waste-fill
components and soil, leaving behind clean materials.   The  mercury
and iodine and iodide are then recovered and recycled.
                               -8-

-------
In  June  1994,  based  upon  successful  laboratory  studies,  G.E.
designed the final conceptual treatment process for the Site, which
consisted of  excavation of  wastes  having mercury  concentrations
above the residential RG of 39 ppm from the West Field,  followed by
a two-step treatment process:

1) physical separation treatment,  consisting of dry screening,  wet
soil washing, and magnetic separation of the materials  to  remove
both  clean  coarse  material  and  high  concentration  materials
containing "free" mercury,  and

2) hydrometallurgical (GEMEP)  treatment of remaining residual wastes
containing non-mobile mercury at concentrations greater than 39 ppm.
Treated materials would be backfilled  in the West Field and covered
with a soil' cover.

In mid-1996,  G.E.  contracted with Metcalf  & Eddy,  Inc.  (M&E)  to
design,  fabricate,  and  operate  the  system,  including  the  waste
separation  (screening/washing)  component  (using (M&E's  Hydrosep
process) and  the  GEMEP treatment  component.  This  contract would
represent the first full-scale application-of the GEMEP technology.

In June  1997,  G.E. initiated excavation  of wastes from the West
Field for physical separation, and construction of the dry screening
and Hydrosep treatment systems.   The physical separation treatment
(screening/washing) of  excavated wastes occurred in conjunction with
the excavation activities.

The estimated duration of the physical separation treatment step of
the  remedy  was  approximately 4  weeks.   However,  the  physical
separation  treatment extended  34 weeks  due  to two  significant
variations  between  the  design  conditions  and  the  conditions
encountered during its implementation at the Site:

1)  The  quantity  of  material that   actually  underwent  physical
treatment was more  than double  the amount originally expected
(11,700 tons versus 5,005 tons),  resulting in an associated increase
in the duration of the physical treatment step, and

2) The actual clay content of the material that underwent treatment
was  much higher  than  expected  (63  percent  versus 18  percent),
resulting in  major production delays  related to  various equipment
operational difficulties.

From June 1997 to  April 1998,  excavation of waste-fill and impacted
soils in  the  West Field and on PRIDCO  property west of the G.E.
facility was completed concurrent with the physical treatment step.
Excavations on PRIDCO property were backfilled with clean off-site


                               -9-

-------
                                                                     *
                                                                       •
 soil,  and  the backfilled area was graded, compacted,  and seeded.
 Clean  (less  than the residential RG of 39 ppm  mercury)  oversized
 material from the physical separation (screening/washing)  treatment
 process  was  returned to the  West Field.   This material,  washed
 plastic components and small stones, was spread along the west wall
 of the West Field excavation and  leveled to an average thickness of
 4 feet.  The excavated slopes  along the east side of the West Field
 and around the cold storage building were  backfilled with off-site
 soil, which was compacted and seeded to protect the slope from water
 erosion.  A new chain link fence  was installed along the  west Site
 boundary between the G.E. facility and the PRIDCO property.

 During physical  separation,  material less  than 1/4-inch,  called
 fines, was stored in piles on a  concrete pad and in  a  second pile
 near the pad while the system was  operational.  After completion and
 demobilization of the physical separation process,  these stockpiles
 were consolidated on the concrete pad.  The settled  fines from all
 three modu-tanks were removed and added  to  the  fines pile on  the
 pad.   Oversized material, greater than 2  inches,  that was  separated
 during physical separation was added to the fines pile on  the  pad
 and surrounded  with concrete barriers  at the  toe.   The entire
 stockpile was then  covered with  four  100-foot by 100-foot tarps,
 which were  secured to the concrete pad around the perimeter of  the
 pile  outside  of the concrete barriers.

 Over   the  34-week   period,   approximately  100  tons  of  high
 concentration wastes containing free mercury were generated from the
 separation  stage.  This waste was  packaged  and transported off-site
 for treatment  in the mainland  United States.

 In May  1998, as a result of the two significant changed conditions
 noted above, EPA and G.E. suspended all Site activities.   The GEMEP
 treatment  system, which was  near completion at  that time,  was
 decommissioned.  Consequently,  no  residual  wastes from the physical
 separation  (screening/washing)  treatment process were treated in the
 GEMEP system.

 At  present,   the  Site  is   in   a  standby  condition   pending
 identification of the final remedial  alternative.    In addition,
 three areas of waste deposition remain to be excavated on the Site.
Access  to material  in these  areas will require either significant
modifications  to  or demolition  (and  relocation)   of   various
 structures, as follows:

o  A small  deposit of material underneath  the  northwest corner of
the cold storage building in the West Field.
                               -10-

-------
o  Two small areas underneath the electrical substation pads on the
eastern side of West Field.

o  A small  area near the northwest corner of  the  maintenance  shop
under the road and plant access ramp.

III. HIGHLIGHTS OP COMMUNITY PARTICIPATION

The Post-Decision Proposed  Plan (PDPP) for the Site was released to
the public  on  April 26,  1999.   The  PDPP,  along with  other Site-
related  documents,   is  available  to  the  public  at  both   the
administrative record and the information repository locations.  A
summary of  the PDPP and  a  notice  as to the availability of those
documents and  the administrative  record was published in  the  San
Juan Star daily newspaper  April 26,  1999,  and in the  El Nova  Pi a
daily newspaper on  May 10,  1999.   A copy of  the public  notice  is
included as an attachment to this  Record of Decision Amendment.

The public comment period began on April 26, 1999  and ended on May
26, 1999.   A public meeting was held on May  13, 1999  at the  City
Hall in  Juana Diaz.   The purpose of the  public  meeting  was  to
discuss  the proposed  changes  to  the  September   1988  Record  of
Decision.

The responses  to  the comments  received during the  public  comment
period as well as those expressed  orally at  the public meeting are
stated in the Responsiveness Summary,  which is  an attachment to  this
Record of Decision.

This Record of Decision Amendment presents the selected modification
to  the  original  remedial  action  for the  disposition of  mercury
impacted materials  located  at  the  Site.   The modification to  the
original remedial action is chosen in accordance  with CERCLA  and,
to the extent practicable, the National Oil and Hazardous Substances
Pollution Contingency Plan  (NCP) , 40  CFR Part  300.   The decision as
made for the Site is based upon  the administrative record. An index
for the administrative record is included as an attachment  to  this
document.   This  Record  of  Decision will  become  a  part  of  the
administrative record file.

The administrative  record file,  containing the information  upon
which the modification to the original remedy is based, is available
at the following locations:

 IV.  REASONS FOR ISSUING THE RECORD OF DECISION AMENDMENT
 GEMEpthni'E' CTfUCted laboratory studies which indicated the
 GEMEP technology would meet ROD requirements.  G.E. added a physical
 ^£art£°^tr?atment Step Pr±0r t0 hydrometallurgical treatment to
 remove both clean coarse material and high concentration materials
             free" mercury.   GEMEP would then treat  the  remaining
            Waf^eS containing non-mobile mercury at  concentrations
      ~     n    Ppm"  Treated materials  would be backfilled  in the
 West  Field and covered  with 2 feet of clean soils.

 During initiation of remedial activities, excavation of waste-fill
       imP  menuati(?n   °f   the   Physical  separation   treatment
                1^ pr,ocLess'  G'E-  encountered Site conditions  that
               differed  from  the  conditions which  served as basic
 assumptions  in developing the 1988 ROD.   These changed conditions
 made  the original remedy less implement able,  and more costly  than
 other remedial  alternatives.

 The significant changed conditions include a 250 percent increase
 in  the  waste  volume;  significant  differences in  the  physical
 characteristics of the  waste  (e.g.,  clay content);  and serious
 concerns regarding the inability to procure the additional quantity
j* J =hemical  extraction   agent   (iodine)  needed   to   complete
rpM^S J   iUrgiCal treatment of the expanded waste volume using the
GEMEP treatment system.   These variations and their impact on the
original remedy are described as  follows:
                               -12-

-------
Waste  Volume  -  The  estimated volume  of  contaminated  material
requiring GEMEP treatment has increased from 4,105  tons  calculated
in  the 1994  Preliminary Design  Report,  to  10,000 tons.    This
increase is  2.5  times  the original estimate of tonnage requiring
hydrometallurgical treatment.  Additional areas to the north,  east,
and  south of  the  originally anticipated  waste  footprint  were
discovered during  excavation activities in  the  West Field.   The
majority of these additional wastes consisted of  fine-grained clay
soils, which are  not conducive to this type of treatment.  Moreover,
the amount of soil to be excavated  as part  of  the  remedy  has more
than quadrupled from the original estimates.

This major increase in the  amount  of material  requiring treatment
will cause the GEMEP treatment system, which is based on  mass,  to
run  significantly  longer   and  cost  significantly   more   than
anticipated.  The increased  tonnage  from the West Field has already
contributed  to  a  significant increase  in  the  duration of  the
excavation  and  physical  treatment  components   of the   remedy.
Furthermore,' the available   space  on-site  to  stockpile materials
awaiting treatment is  limited,  and has required the placement of
residual  materials  in  overflow  storage  areas  outside  of  the
containment pad  for the treatment system.

Waste Composition - The  content of  fine  soils  (i.e., clay)  in the
materials from the West  Field is  much  greater  than anticipated in
the  remedial design.    While the  remedial design assumed  that
approximately 34 percent of  the materials would  consist of fines,
grain-si.ze analyses performed during implementation of the physical
treatment indicated  that the  wastes  consist of approximately 85
percent fines.  The tests also showed that about  63 percent of the
material is clay-sized.

The overall impact of these changes is a significant increase in the
amount of clay materials requiring treatment, which is  expected to
result in substantial materials handling difficulties.  These new
waste  characteristics  have  already  caused  the  excavation  and
physical treatment components to far exceed the original schedule.
For  example,  the physical  separation  (screening/washing-)  process
required 34 weeks to complete, in comparison to  the projected 4-week
schedule.  The high clay content coupled with the increased volume
caused  plugging and  fouling  of  the dry  screening and  Hydrosep
process component  of  the physical separation treatment  equipment.
These materials handling problems lead to an increase in time spent
on  equipment maintenance,  resulting  in  project delays.   Similar
setbacks to the  GEMEP time frame are now expected due to materials
handling and dewatering  difficulties.

The  comprehensive  Environmental  Response,   Compensation
Liability Act  (CERCLA)  requires that  each selected li^erem'e
protective of human health and the environment, be cost^eflScve
comply with other laws,  and use permanent solutions and \?ternatlve
treatment technologies  and resource recovery  alternatives  to
maximum  extent  practicable.    in  addition!  CERCLA  includes
                               -14-

-------
preference  for  treatment  as  a principle element for the reduction
of toxicity, mobility, or volume of the hazardous substances.

The present-worth costs presented below for each alternative include
capital costs and operation  and maintenance (O&M)  costs.   The O&M
costs are for post-remediation monitoring of the Site over a three-
year period.

ALTERNATIVE  1  - EXISTING REMEDY IN THE SEPTEMBER 1988 RECORD OF
DECISION

Hydrometallurgical Treatment and Subsequent On-site Replacement of
the Treated Material

This alternative is defined as the selected remedy in the September
1988 Record of  Decision.   The original remedy addresses  mercury
contamination  in  the  waste-fill  area  known as  the West  Field,
including the waste-fill materials, contaminated near-surface soils,
and perched ground water expected to  be encountered in the  West
Field having mercury concentrations above the health-based  cleanup
levels specified by EPA.  Major remedy components are:

o  Further treatability studies during remedial design to insure the
implementability  of  hydrometallurgical  processes,   as well  as
continued study of other treatment alternatives.

o  On-site hydrometallurgical treatment of the waste-fill materials
(approximately 4,000 cubic yards), perched water (approximately 0.5
million gallons) ,  and contaminated near surface soils (approximately
1,500 cubic yards).

o   Treatment of  the  material  to  below  health-based levels  and
backfilling the waste-fill area with  the treated materials.   The
area would then be covered with 2  feet of clean soil.

o  Additional investigation  of the  ground  water to  determine the
extent of groundwater contamination.

o  Limited  groundwater monitoring (i.e.,  for  a minimum of  three
years),  provided  that  the  additional  groundwater  investigation
establishes that there is no need for groundwater remediation.

o    Confirmatory  air  monitoring   and  re-sampling  of soil  in
residential yards.

The hydrometallurgical treatment component is described in  further
detail in the 1988 ROD on pages 18  and 19 as follows:
                               -15-

-------
 "This alternative  involves  putting the mercury  into  solution by
 using a leaching agent such as cyanide, hypochlorite or nitric acid.
 The mercury would  then be recovered from  the aqueous  solution by
 using various  metallurgical  techniques  such  as  filtration  and
 cementation/precipitation.    The waste  would be  mixed  with  the
 leaching  agent until the desired level of mercury  is extracted from
 the waste  and  put into  solution.    The  process  stream  from  the
 leaching  stage would then be filtered.  The residue from filtering
 would be  disposed  of in the former waste-fill area and capped with
 two feet  of clean  soil.   The process would be designed to achieve
 treatment of mercury  from the waste to below health-based levels.
 Since it  is  anticipated  that  the treatment  process could attain
 treatment  of  mercury  to  below acceptable  levels,  the  actual
 performance standard for the treatment process would be determined
 by the maximum removal efficiency  associated with  the  technology
 with  due  consideration  to  the corresponding  incremental  cost
 involved  in achieving further removal.  The  mercury-laden liquid
 from the  filtering  stage would then be subjected to cementation or
 precipitation.   This  process  is achieved  by passing the liquid
 through  a  material such  as  stainless  steel,   zinc,  copper  or
 aluminum.

 During cementation the mercury  is   exchanged with  the metal  and
 precipitated out.   The liquid  would then  be recycled back through
 the  process.  It is anticipated that only one batch of  leaching
 agent  would  be  needed.   Upon  completion  of  the  process,  the
 remaining  liquid would be  treated on-site  prior to  discharge to a
 POTW.  Further treatability studies  will be conducted during design
 to optimize  the treatment process.   The process would be  designed
 to meet or exceed levels protective of public health."

 The  conceptual  hydrometallurgical  treatment  component  described
 above  in  the   1988   ROD  differs   from   the  particular  GEMEP
 hydrometallurgical  treatment system  which  was ultimately  designed
 for  the Site in two significant ways:

 1)   The ROD  did not consider a physical separation  treatment step
 that would remove both clean,  coarse  material and high concentration
metallic    debris    from    the    materials   to   be    treated
hydrometallurgically.

2)   The ROD  called  for use of a  readily available leaching agent,
 such   as   cyanide,  hypochlorite or  nitric  acid/5  which  were
subsequently determined to be ineffective  based upon treatability
study results. The GEMEP uses iodine, which was never evaluated or
even considered in the ROD as a leaching agent.
                               -16-

-------
The  estimated incremental  cost  of implementing Alternative  1 is
$8,810,3191,  including  the   cost  of  post-closure  groundwater
monitoring.  This estimate considers the on-site treatment of 10,000
tons of residual material and its subsequent backfill over a 52-week
period,  and iodine losses  equivalent to one percent of the total
feed material.

ALTERNATIVE  2 -  MODIFIED  REMEDY  AS SELECTED  IN  THIS RECORD OF
DECISION AMENDMENT

Off-site Disposal of all  Remaining Site  Wastes  in a  Subtitle  C
(hazardous  waste)  Landfill  in the Mainland United  States  Without
Further  Treatment

This alternative is defined as the  selected remedy in the Record of
Decision Amendment.    It  does  not  modify the remediation  goal
established  by  EPA in the  1993  Baseline Risk Assessment  for the
Site, which calculated a residential RG of 39 ppm for mercury levels
in soil.

This alternative eliminates the on-site hydrometallurgical treatment
component of  the  remedy, including the on-site backfilling of the
treated material.  All remaining  mercury- impacted materials at the
Site will be excavated, including the clean, washed coarse materials
(mercury concentration below the  residential RG of 39 ppm) that were
backfilled  in the  West, Field  and contaminated  materials remaining
underneath  structures  in  three  discrete  areas    (cold  storage
building, electrical substation pads, and maintenance shop).

Approximately 10,000 tons of mercury impacted fines and 1,600 tons
of clean, oversized material  currently in the West  Field  will be
placed into containers called Lift Liners.  It is currently expected
the 11,600 tons of containerized material will  be  transported to a
permitted RCRA  Subtitle  C hazardous waste landfill  in Pinewood,
South Carolina (via truck to Ponce, by covered barge to Charleston,
and by truck to Pinewood).

Excavation  areas  will  be  backfilled   with  imported  clean  fill
material.  The backfilled areas will be  graded and seeded to support
revegetation, and will be made  available for productive future use.
      xThis cost is in addition to the costs GE'has spent on the
 physical  separation  treatment  and off-site disposal  of highly
 concentrated wastes.

                               -17-

                                                                     •
                                                                       «•
 The estimated total cost of Alternative 2 is $3,447,522',  based on
• 11,600 tons of material to be loaded into Lift Liners at a rate of
 20 containers per day.

 VI.  EVALUATION OF ALTERNATIVES

 In  accordance with  the NCP,  this  section presents  a  detailed
 analysis  of  the.  original  remedy  and  the  alternative  remedy
 considered in the preceding section.  The detailed analysis consists
 of an assessment of the two alternatives against each of the NCP's
 nine evaluation criteria and a comparative  analysis  focusing upon
 the relative performance of each alternative against those criteria.

 The  following  "threshold"  criteria  must   be  satisfied  by  an
 alternative to be eligible for selection:

 1.   Overall  protection  of  human  health   and  the  environment
 addresses whether or not a  remedy provides adequate protection and
 describes how risks posed through  each exposure pathway (based on
 a reasonable maximum exposure scenario) are eliminated,  reduced, or
 controlled through treatment, engineering controls, or institutional
 controls;

 2.   Compliance  with  applicable  or  relevant   and  appropriate
 requirements (ARARs) addresses whether or not a remedy will meet all
 of the applicable  or relevant and appropriate federal and  state
 environmental  statutes  and requirements  (i.e..  those  federal  or
 state  laws that  'specifically   address   a   hazardous   substance,
 pollutant or  contaminant,  remedial  action  or other circumstance
 found at a  CERCLA  site,  or which  address problems or  situations
 sufficiently similar to those encountered at  a  site that their use
 is well  suited  to the  site)  or  provide grounds  for  invoking a
 waiver.

 The   following  "primary  balancing"  criteria  are used  to  make
 comparisons  and  to   identify  the   major  trade-offs  between
 alternatives:

 3.    Long-term effectiveness and permanence refers to  the ability
 of a remedy to maintain reliable protection of human health and the
 environment over time,  once cleanup goals have  been met;

 4.    Reduction of  toxicity,  mobility, or volume through treatment
 refers to the degree to which remedial alternatives employ recycling
                                -18-

-------
 *
•»•
      or treatment  that  reduces the  toxicity,  mobility, or  volume of
      hazardous substances at a site;

      5.   Short-term effectiveness addresses the period of time needed
      to achieve protection and any adverse impacts on human health and
      the environment  that may  be posed  during the  construction and
      implementation periods until  cleanup  goals  are achieved;

      6.   Implexnentability refers to  the  technical and administrative
      feasibility of a remedy, including the availability of the materials
      and services  needed to implement a  particular  option;  and,

      7.   Cost includes  estimated  capital  and operation  and maintenance
      costs, and net present-worth costs for alternatives expected to last
      more than two years.

      The following "modifying" criteria are considered  fully after the
      formal public comment period  on  the Post-Decision Proposed  Plan is
      completed:

      8.   State acceptance indicates whether, based on its review of the
      remedial  investigation/feasibility  study  (RI/FS), and  the proposed
      plan,  the State  supports,   opposes,  and/or  has  identified any
      reservations  with the preferred  alternative; and,

      9.   Tribal/Community acceptance refers  to the  public's  general
      response  to the alternatives described in the proposed  plan and the
      RI/FS reports;  factors of community acceptance to  be discussed
      include support, reservation,  and opposition by the tribe/community.

      The  following  section  presents a comparative  analysis  of the
      alternatives  based  upon these evaluation criteria.  The comparative
      analysis   focuses  upon  the   essential  differences   in   the two
      alternatives:

      Alternative I - Hydrometallurgical Treatment Using the  GEMEP System
      and Subsequent On-site Replacement  of the  Treated Material, and

      Alternative 2 -  Off-site Disposal of  all Site  Wastes in a  Subtitle
      C (hazardous  waste) Landfill  in  the Mainland United States  Without
      Further  Treatment.

      1.   Overall  Protection of Human Health &  the  Environment

      Both alternatives  would be  protective of  human  health  and the
      environment by preventing direct exposure  to  mercury-contaminated
      materials.   Alternative 1 would permanently  reduce  the  mercury
      concentration in residual materials to less than the residential RG


                                     -19-

-------

 of 39 ppm by treating the materials on-site using the  GEMEP system.
 The treated materials would then be backfilled in the West Field.
 For Alternative 2,  all materials containing mercury in excess of 39
 ppm would be disposed off-site at an EPA-approved, RCRA-permitted
 (Subtitle C) disposal  facility.

 2.   Compliance  with  Applicable,  or  Relevant  and Appropriate
 Requirements (ARARs)

 Both  alternatives  would  achieve  Applicable  or   Relevant  and
 Appropriate Requirements  (ARARs),  which include all federal  and
 Commonwealth regulations and public health regulations that address
 a  hazardous  substance,  pollutant,  contaminant,  remedial action,
 location,   or  other  circumstance   at  a - site.     Three  ARAR
 classifications exist:

 o    chemical-specific  ARARs,   which 'are  health-  or  risk-based
 concentration  limits  of  chemicals which  may  be  found in,  or
 discharged to,  the  ambient  environment;

 o   location-specific, which are based on the geographical location
 of a site  and its surroundings; and

 o    action-specific,  which  are  typically  technology-based  or
 activity-based requirements or limitations on  actions  taken with
 respect to hazardous substances, pollutants, or contaminants.

 No chemical-specific ARARs were  identified for Alternative  1  or
 Alternative 2.  Both alternatives would achieve the residential RG
 of 39 ppm for  mercury  by  removing  materials  that  exceed  this
 criterion  from  the  Site by on-site treatment or off-site disposal,
 respectively.

 No location-specific ARARs  have been  identified for  Alternative 1
 or Alternative  2.

Action-specific ARARs  for Alternatives 1 and 2 would include  air
 emissions and OSHA health and safety requirements.  In  addition,  the
RCRA guidelines for facility operation  would  apply to Alternative
 1,  and the RCRA guidelines for generators, land disposal and waste
 transportation  would apply to Alternative 2.

3.    Long-Term  Effectiveness and Permanence

Both  alternatives  would   achieve  long-term  effectiveness  and
permanence.
                               -20-

-------
For Alternative  1,  approximately  10,000 tons  of  stockpiled  and
unexcavated residual materials would be  treated on-site using  the
GEMEP system to achieve the 39 ppm cleanup goal, and then backfilled
in the West  Field and covered with a  clean soil cap.  Hazardous
GEMEP process residuals,  including elemental mercury and spent iron
filings,  would be sent off-site to an EPA-approved facility  for
recycling or disposal.

For  Alternative   2,   all  residual  materials  containing   mercury
concentrations in excess of  39 ppm -and clean coarse materials
previously backfilled  in  the  West  Field would be  transported  off
site  to  an  EPA-approved,  RCRA-permitted  (Subtitle  C)   disposal
facility,  which   is  specifically  designed  to  provide long-term
effectiveness and permanence for disposal of RCRA-hazardous wastes.
Most  of  the materials  requiring off-site disposal  under this
alternative have undergone physical treatment to remove any mobile
mercury,  rendering the materials as non-hazardous.

4.    Reduction in Toxicitv.  Mobility,  or Volume Through Treatment

The toxicity, mobility,  and volume of mercury  contamination were
reduced at the Site  as a  result of prior remedial activities, which
included excavation and physical treatment to remove mobile mercury.

Alternative  1 would achieve  further reductions  in  waste  toxicity,
mobility, and volume by using the on-site GEMEP treatment system to
remove mercury from residual materials to concentrations  below  the
39  ppm RG.   The clean  soil cap  would  also  reduce  mobility by
preventing  erosional   transport  of  backfilled  materials, which
contain residual mercury below 39 ppm.

Alternative  2 would achieve  a further  reduction in waste  mobility
by transporting residual materials containing mercury in excess of
the 39 ppm RG to an off-site, RCRA-permitted (Subtitle C)  disposal
facility without  further  treatment, which is  designed to effectively
and permanently contain RCRA hazardous wastes.  Waste toxicity and
volume would not be effectively reduced; however,  the contaminated
materials would  be  removed  from the Site as a  result  of  off-site
disposal.

5.   Short-Term Effectiveness

Both alternatives involve short-term  risks  during the performance
of remediation work, which are considered to be manageable through
the  implementation of standard  administrative,   procedural,  and
engineering  controls.  However, from a comparative standpoint,  the
short-term,risks associated with Alternative 2 are  considered to be
                               -21-

-------
 lower than Alternative i based upon the anticipated duration of work
 and the controls required to prevent exposure.

 Short-term  risks  associated  with  Alternative  1  include  worker
 exposure to hazardous chemicals required for GEMEP treatment system
 operation.  Risks  associated with residential  exposure  would also
 exist to a lesser extent due to potential  emissions  resulting from
 GEMEP  treatment  system operation.    Standard administrative  and
 procedural  controls  would  be  employed  to  prevent   accidents
 associated with handling of process  chemicals and residual  wastes.
 Exposure to treatment system emissions and dust would be prevented
 by the implementation of engineering controls, such as water sprays.
 These risks would exist for an extended period of one to two years
 to  implement  the  remedy,  based   upon   the  anticipated   system
 maintenance requirements  (intensive),  increased  waste volume  for
 treatment,  and  waste  characteristics (higher  clay  content,less
 suitable for treatment).

 Short-term risks associated with Alternative 2 include worker  and
 residential exposure to waste materials and wind-blown particulate
 during off-site handling and transport. Engineering  controls,  such
 as the use  of secure  shipping  containers and methods,  would be
 implemented to prevent exposure  to wastes during  their off-site
 transport.    Dust  controls,  such as  water  or  foam  sprays,  and
 standard procedures would also be implemented to prevent exposure
 associated with any off-site handling  of waste.   These risks  would
 exist for a duration of approximately three months  to  implement this
 alternative.

 6.   Implementability

 Alternative  1 would be  difficult  to implement  based  upon  the
 following factors:

 o   treatment of  the increased  volume of residual material would
 require the procurement of 60 tons of iodine,  in addition  to the 40
 tons (32 tons  of  iodine and 8  tons  of potassium iodide)already in
 G.E.'s possession, which would be difficult based upon its limited
 availability on the  world market;

 o   uncertainties  associated with iodine consumption  by  the GEMEP
 treatment process could require subsequent procurement of
 additional iodine above the 60-ton estimate; and

 o  the  increased  clay content would cause frequent fouling of GEMEP
 system  filters,   centrifuges,  filter presses,  and  downstream
processes in general.
                               -22-

-------
Alternative 2 could be readily implemented using standard equipment
and services associated with transporting residual  materials  to a
RCRA-permitted  (Subtitle  C  landfill),  off-site disposal  facility
approved by EPA.

7.   Cost

Cost estimates  for implementing  each  alternative  were  developed
considering  direct capital  costs,   indirect  capital  costs,   and
operation and maintenance costs in accordance  with EPA's "Guidance
for Conducting Remedial Investigations and Feasibility Studies Under
CERCLA."

The  estimated  total  cost  of   implementing Alternative  1  is
$8,810,319.  This estimate considers the on-site treatment of 10,000
tons of residual material and it's subsequent backfill over a 52-week
period, and  iodine  losses equivalent to  one percent of  the total
feed  material.     It  also   includes  the  cost   of post-closure
groundwater  monitoring.   The  following four  cases  illustrate the
cost impact associated with varying key assumptions:

o  Case 1 - 10,000  tons of material, 52 weeks,  and 2 percent iodine
            loss.   Estimated total cost:   $10,696,319

o  Case 2 -. 10,000  tons of material, 40 weeks,  and 1 percent iodine
            loss.   Estimated total cost:   $ 7,884,433

o  Case 3 - 10,000  tons of material, 70 weeks,  and 1 percent iodine
            loss.   Estimated total cost:   $10,199,045

o  Case 4 - 13,000  tons of material, 52 weeks,  and 1 percent iodine
           , loss.   Estimated total cost:   $11,431,002

The estimated total cost of  Alternative 2 is  $3,447,522.   This
estimate considers the off-site disposal  of 11,600 tons of residual
material at a RCRA-permitted,  Subtitle  C landfill.  It  was assumed
that the residual materials would be loaded into  Lift  Liners  at a
rate of 20  containers per day.   The following three cases -illustrate
the cost impact associated with varying key assumptions:

o  Case 1  -  11,600 tons at 10 Lift Liners per day.
            Estimated total cost:  $3,609,897

o  Case 2  - 11,600 tons at 30 Lift Liners per day.
            Estimated total cost:  $3,393,811

o  Case 3  -  14,600 tons at 20 Lift Liners per day.
             Estimated total cost:  $4,150,802


                               -23-

  8-   Commonwealth Acceptance

  The Commonwealth of  Puerto Rico concurred with the off-site disposal
  alternative in November 1998.

  9-   Community Acceptance

  Community Acceptance is addressed in the Appendix 2 Responsiveness
  Summary.  In general, the community appears  to have no objections
  to Alternative 2.

 VII. SELECTED REMEDY

 Based on considerations of the requirements of CERCIA,  the detailed
 analysis of the alternatives,  and the  comments received during  the
 public comment period,  EPA has determined that Alternative 2, off-
 site disposal of  mercury impacted materials  in  a permitted RCRA
 Subtitle C hazardous waste landfill, is the most appropriate remedy
 for the Site.  As described, Alternative 2 would replace Alternative
 1,   hydrometallurgical  treatment  using  the  GEMEP   system   and
 subsequent on-site replacement of the  treated material.   All other
 components of  the original remedy will remain the same.

 Alternative  2  encompasses  the  complete excavation  of  remaining
 mercury-impacted materials on the Site, including  the washed coarse
 material that  was determined to be below the residential RG of 39
 ppm and was  backfilled  in  the  West  Field,   as well  as   the-
 contaminated materials  remaining underneath  the  cold  storage
 building,  electrical substation pads,  and maintenance  shop.

 Off-site disposal provides the best balance of trade-offs  among  the
 two alternatives with respect  to  the NCP  evaluation criteria.   EPA
 believes  Alternative   2   will   provide   comparable    overall
 protectiveness  of   human  health and  the  environment,   greater
 implementability,  fewer short-term risks, and significantly lower
 costs  when  compared to the  GEMEP treatment system  and  on-site
 disposal  of  treated materials.    Alternative 2  also  could  be
 implemented within a  few months and is consistent with Site-specific
 cleanup  levels.

VIII. STATUTORY DETERMINATIONS

Under CERCLA and the NCP, EPA's responsibility at Superfund sites
is to undertake remedial actions  that  achieve adequate protection
of human health and  the- environment.   In addition,  Section 121  of
CERCLA  establishes  several   other  statutory  requirements   and
preferences  that  the selected remedy  must  meet.    Section  121  of
CERCLA specifies that when complete, the  selected remedial action


                               -24-

-------
for the Site must comply with ARARs established under  federal  and
state environmental laws unless  a statutory waiver  is  justified.
The selected remedy also must be  cost-effective and  use permanent
solutions  and  alternative  treatment  technologies  or  resource
recovery technologies to the maximum extent  practicable.  Finally,
the statute includes a preference for remedies that employ treatment
that permanently and significantly reduces the volume, toxicity,  or
mobility  of hazardous  wastes  as their principal element.    The
following  sections  discuss how  the modified  remedy meets  these
statutory requirements.

1.    Protection of Human Health and the Environment

The modified remedy maintains a comparable  level  of  protection of
human health and the environment  as the original  remedy set  forth
in  the  1988  Record  of  Decision.   Complete  excavation  will  be
performed  to  remove  all  remaining  mercury-impacted  materials,
thereby achieving the residential RG of 39 ppm,  as calculated in the
Baseline Risk Assessment for the Site  in 1993.  The modified remedy
includes the excavation  of  clean,  washed coarse materials that were
backfilled in the West  Field and  contaminated materials remaining
underneath  structures   in  the  three  aforementioned areas.    The
removal of all Site contaminants  to the established  cleanup  level
will mitigate the health threats  posed  at the Site,  primarily the
i.ngestion  of soil and  waste by  local residents,  by  minimizing
exposure to the mercury-impacted materials.

The off-site landfilling of all  materials  containing  mercury in
excess of  39  ppm at  an EPA-approved, RCRA-permitted (Subtitle C)
disposal facility where adequate engineering controls are  provided
will  permanently remove  those  contaminants  from  the Site  and
encapsulate them in a secure and monitored containment  system.

2.    Compliance  with  Applicable.  or  Relevant  and  Appropriate
Requirements  (ARARs)

The original  analysis with respect  to ARARs,  as  contained in the
1988 Record  of Decision, held that  the  original  remedy did comply
with all federal and state ARARs.

The key element which is changed  in the modified remedy will also
comply with federal and  state  ARARs.  The modified  remedy will
comply  with  air emissions  and  Occupational Safety   and  Health
Administration  (OSHA)   requirements.   In addition,  the  modified
remedy will comply with  applicable or  relevant  and appropriate RCRA
requirements  and/or  corresponding  state  requirements  for  the
identification, transportation,  storage, treatment and disposal of
hazardous waste  (40 CFR Parts 261 through 264  and  268).


                               -25-

-------
 The off-site  disposal  facility which  is expected to  be used is
 located in the State of South Carolina; those State requirements for
 hazardous wastes will be met by the disposal facility  to the extent
 applicable.    All necessary approvals  will be  obtained prior to
 disposal to  ensure the excavated materials meet  the  facility's
 permit restrictions.

 3.    Cost-Effectiveness

 Cost-effectiveness  is a critical component used in the balancing of
 the evaluation  criteria.   With the  250  percent  increase  in the
 estimated volume of waste  requiring hydrometallurgical  treatment,
 the estimated total  cost  of  the  original remedy  increased  from
 $1,912,870  (in 1988 dollars) to $8,810,3192 (in  1999 dollars).  The
 cost savings associated with off-site disposal,  rather than on-site
 treatment,  was  therefore  a  factor which  eventually led  to the
 selection of  the modifications  as  opposed to the original remedy.

 The estimated total cost for the modified  remedy,  also based on the
 revised  waste  volume estimates,  is $3,447,5222.

 4-    Utilization of  Permanent  Solutions and Alternative Treatment
 Technologies  (or Resource Recovery Technologies) to  the Maximum
 Extent Practicable

 This  statutory   determination  is  satisfied   by the  selected
 modification.

 EPA believes that, based on the  information that was available when
 the  Record  of Decision was  issued  in  1988,  the  original  remedy
 represented  the  maximum extent  to which permanent solutions and
 treatment technologies  could have  been used in  a  cost-effective
 manner at the Site.  We also believe that the modified remedy uses
permanent solutions and alternative treatment  technologies  to the
maximum extent practicable after consideration  of the most  recent
volumetric and cost estimates and mitigating factors associated with
the  implementability of the GEMEP  treatment system.

5-   Preference  for Treatment as a  Principal Element

For the modified remedy, the preference for treatment  is satisfied
since most of the materials  requiring off-site disposal have already
      2This cost is in addition to the costs GE has spent on the
physical  separation  treatment  and off-site disposal  of highly
concentrated  wastes.
                               -26-

      undergone the physical separation phase o£ GEMEP treatment to remove
      mobile mercury.  Additionally,  all  residual  materials  containing
      mercury  concentrations   in  excess  of  39  ppm  and  clean  coarse
      materials  previously  backfilled  in  the  West  Field  will   be
      transported off-site to  an EPA-approved, RCRA-permitted (Subtitle
      C)   disposal  facility,  designed  to  effectively  and  permanently
      contain RCRA-hazardous wastes.

      IX.  DOCUMENTATION OP SIGNIFICANT CHANGE

      There are no  significant  changes from the preferred alternative,  as
      presented in  the  Post-Decision Proposed Plan released to the public
      on April 26,  1999.

                      RESPONSIVENESS SUMMARY

                G.E. WIRING DEVICES SUPERPDND SITE
                      JUANA DIAZ,  PUERTO RICO
 In accordance  with Sections  113 and  117 of  the  Comprehensive
 Environmental Response, Compensation and Liability Act, as amended,
 EPA has conducted  community involvement  activities at the  G.E.
 Wiring Devices Superfund Site  (the  "Site")  to solicit  community
 input  and  ensure that  the public  remains  informed about  Site
 activities.  EPA's Post-Decision Proposed Plan was released to the
.public on April 26, 1999.   A  copy of the Post-Decision  Proposed
 Plan was placed in the  Administrative Record and was made available
 in the information repository at the Press Office  at  the  Mayor's
 Office, Juana Diaz City Hall. A public notice was published in the
 San Juan Star in San Juan, Puerto Rico on April 26,  1999,  advising
 the public  of  the availability  of  the Post-Decision Proposed  Plan
 and the Focused Feasibility Study,  and the date of  the  upcoming
 public meeting.   The public notice also was published in El Nuevo
 Dia in San  Juan on May 10,  1999.

 During the public  comment  period, EPA held  a public meeting  at
 Juana  Diaz City  Hall  on May  13,  1999,  to  answer  questions  and
 receive comments  on  the   Agency's preferred alternative   for
 addressing Site contamination.   Comments received during the public
 meeting were recorded in an  official  transcript; a copy is included
 in the Administrative Record  and information repository.    The
 public comment  period  opened on April 26, 1999 and  closed on May
 25, 1999.

 This   responsiveness   summary  provides  information  about   the
 community's views regarding EPA's proposed action,  documents  how
 the Agency has considered  public comments  during  the  decision-
 making process,  and provides answers to  major comments  received
 during the public  comment  period.   EPA  received many  comments
 regarding  issues  unrelated  to EPA's proposed remedy change.   All
 comments  are summarized in this  document;  however,  only those
 comments  related  to  the  proposed  remedy  change  for  off-site
 disposal have been considered in EPA's final decision for selection
 of a remedial alternative for the  Site.

 These  sections  follow:

 o    Overview:  This section discusses  the  recommended action for
     the Site and  the  public reaction to  this alternative.

-------
 o    Background on Community Involvement:  This section provides a
      brief history of community interest in the Site and identifies
      key public issues.

 o    Summary of Comments Received During the Public Comment Period
      and Agency Responses:   This section provides  EPA's responses
      to oral  and  written  comments submitted during  the  public
      comment period,  and  is divided into two parts,  as  follows.

           Part I:   Summary and Response to Local Community Concerns
           Part II:  Comprehensive Response  to Specific  Legal and
           Technical Questions

 o    Remaining  Concerns:    This  section  discusses issues and
      concerns that EPA was unable to address during the remedial
      planning activities.

 o    Attachment A - Community Relations  Activities at G.E.  Wiring
      Devices Superfund Site:  This attachment contains  a list of
      community relations activities conducted at the  Site to date.

 A.    OVERVIEW

 At  the time of  the public comment period,  EPA  had  identified  a
 preferred  alternative for  the  Site,  which  would  replace only  a
 focused portion  of  the September 30, 1988 Record  of Decision.  EPA
 documented  this change in its Post-Decision Proposed Plan, dated
 April 26, 1999.  The recommended alternative  involves the off-site
 disposal of all remaining Site wastes at a permitted RCRA Subtitle
 C hazardous waste  landfill  located on the mainland United States,
 in  place  of on-site  treatment and backfill  of  processed  wastes
 using the G.E. Mercury Extraction Process treatment system, which
 was a part of  the  original  remedy.

 This modification  is in direct response to significant variations
 in  Site conditions which were encountered during  excavation and
 construction phases of the original remedy.   These variations made
 the original,  remedy less  effective,  less implementable, and more
 costly  than other  remedial  alternatives.  EPA has not changed the
 mercury cleanup level  it   adopted  for  the  Site in  1993,  which
 remains at the residential preliminary remediation goal  (PRG) of 39
parts per million  (ppm).

Judging  from  the  comments  received during  the  public comment
period,  local residents  and  other  concerned parties   generally
 support the Post-Decision  Proposed Plan,  and agree that off-site
disposal provides  equivalent protection of  human  health and the
environment, greater implementability, fewer  short-term risks, and
significantly  lower costs  when compared  to  the  original remedy.

-------
The public also understands that the preferred alternative would be
accomplished within  a few  months and  is  consistent  with Site-
specific cleanup requirements.

B.   BACKGROUND ON COMMUNITY INVOLVEMENT

Since discovery  of environmental problems  at the Site,  EPA has
worked closely with residents in the affected  community to solicit
their concerns  and answer  their questions  on a  regular basis.
Based upon community  reaction,  EPA  has  revised its  Community
Relations  Plan  for  the  Site  twice,   prior  to  the  Remedial
Design/Remedial Action  phase in  July 1992 and  at the start  of
Remedial Action activities in May 1997.

During community interviews conducted in April 1992,  residents in
the neighborhood  adjacent to the Site  expressed  their concerns
about three main issues:   1)  lack of sufficient information on the
Superfund  process  and how it applies to the  Site,  2)  potential
effects  of the  Site  contamination  on public  health and  the
environment, and 3) their reaction to sampling activities.

In March 1997,  issues and concerns solicited during the community
interviews  were  focused on  issues related  more closely  to the
Remedial Action.  These included:

o  Off-site migration of contamination
o  Cleanup technology and schedule
o  Current monitoring activities
o  Public health and safety
o  Ongoing communication efforts.

In August  1997, EPA prepared and distributed  a fact  sheet to the
community in English and in  Spanish which directly addressed these
community concerns in a special question-and-answer section.
The major concerns and how EPA addressed them  are presented below:

(1)  Residents were concerned that Site  contamination could reach
the ground water and migrate to  their  properties during heavy rain
and flood conditions.

     EPA Response:  Mercury has not migrated from  those areas where
plastic and other  scrap materials were  deposited.   Surface water
runoff from the fill  area is controlled, and will continue to be
controlled throughout the cleanup. Run-off to adjacent residences
is  from  the  south  field,   an  area  of  property which   is  not
contaminated.

-------
  (2)    Residents  requested  more   information  on  the  cleanup
 technology, an explanation of the term "clean soil," and an overall
 time frame for the cleanup process.

      EPA Response:  EPA described the cleanup technology in basic
 language in  the August 1997  fact  sheet.   EPA also defined  its
 established  cleanup  level for mercury  in soil  as  39 parts  per
 million.   The fact sheet  presented a  project schedule  with major
 milestones and anticipated completion dates.   In addition, EPA held
 an informational meeting with the community  on September 23,  1997
 to 'discuss the cleanup technology and answer questions.

 (3)  Residents expressed some confusion  about sampling  events  and
 requested their soil  sampling results.

      EPA Response:  In May 1997, EPA prepared  letters and sent them
 to residents on Calle  #2  whose properties were sampled  in 1993.
 The letters presented the sampling results and compared the mercury
 concentrations  found  in  the samples with  the  cleanup  levels
 considered by EPA to  be safe for human health.  The  letters also
 contained information on the  potential health effects of  exposure
 to mercury.

 (4)   The^community wanted  to  know if G.E. Wiring  continued  to  use
 mercury in  its manufacturing  process?

      EPA  Response:   G.E.  Wiring  has not  used  mercury  in  its
 manufacturing process  at the  Juana  Diaz facility  since  1970.

 (5)  Residents wanted  to know  the whereabouts and contents of drums
 that  were once located  near G.E.  property.

      EPA Response:  Drums  were used to contain  materials produced
 during soil sampling and well installation activities.  The drums
 were  sent off-site for proper disposal.

 (6)   Residents asked about the purpose of red markers observed in
 back  of the G.E. facility.

      EPA  Response:    The  red markers   identify  soil  sampling
 locations.

 (7)  Residents wanted  to know what steps would be taken to minimize
disturbances to residents and their  properties during  the cleanup.
In particular, during the excavation and construction activities,
they were concerned about the spread of rodents to nearby houses.

     EPA Response:   G.E.  will take precautions normal  to  other
construction projects  in Puerto  Rico,  including  the  use of silt

-------
 fencing,  control of working hours,  etc.   In addition, G.E.  will
 provide temporary visual barriers and take steps to minimize noise.
 G.E.  will  hire  a local  exterminator  to control  rodents.

 (8)   The community asked about specific measures G.E.  will  take  to
 maintain the  formerly contaminated site.

      EPA  Response:   G.E.  will  replant  the Site  with grass and
 maintain  a cover on the former  waste-fill  area.   G.E. will  also
 maintain a fence around the Site.

 (9)   The community expressed concern about a possible  link  between
 the  Site  contamination and various  illnesses  in their families.
 They  wanted to  know whether  mercury exposure  could  cause human
 health problems, such  as  cancer, Parkinson's Disease, asthma,  or
 allergies,  and asked about available studies on the subject.   They
 also  were  concerned about health risks to current G.E. employees.

      EPA Response:   There is no clear medical evidence  that  mercury
 can cause  cancer, allergies, or  Parkinson's  Disease in humans.
 Extreme  exposure to  mercury  can cause  harmful  effects  on the
 central nervous system and kidney.  Lung  reactions  can also result
 from  inhalation exposure to mercury vapors,  while stomach problems
 may  follow significant swallowing of  organic  mercury compounds.
 Body  levels of  mercury  can be accurately determined using  either
 blood or urine samples.

 The potential risk associated with mercury exposure to GE  factory
 employees  and neighboring residences resulting from  the  cleanup
 work  to be  completed and the residual mercury level, (below the  39
 ppm PRO) to be  left in placed is  considered to be minimal.  EPA
 will use cleanup methods at this  site that are designed to  prevent
 environmental releases.

 (10)   Residents,  local officials,  and other interested  parties  were
 eager to receive information on  cleanup activities, and suggested
 a variety of techniques  to stay informed of Site news.   The Mayor's
 Office in cooperation with the Press Office expressed a willingness
 to distribute  information  to  the  community, and  to relocate the
 information repository to Juana  Diaz City Hall.

     EPA Response:  Residents will be kept  informed  through the
 information repository, which  was relocated to the Mayor's Press
Office  at   Juana Diaz  City Hall,  and  through distribution  of
periodic newsletters and fact  sheets.   EPA will inform the local
community  of  completion of the  cleanup  project through a public
notice.    (See Attachment A for  a complete  listing of community
relations activities at the Site.)

 C.    SUMMARY OF COMMENTS RECEIVED DURING THE PUBLIC COMMENT PERIOD
      AND AGENCY RESPONSES

 The public  comment  period  on the  Focused  Feasibility Study and
 Post-Decision Proposed Plan was held from April 26, 1999 to May 25,
 1999.   The following correspondence was  received  during that  time
 period:

 o     Letter from  Rene R. Rodriguez  (citizen) dated May 17,  1999
 o     Letter from  the General  Electric Company dated May 22, 1999

 A summary of the  comments  contained in the above  letters  and the
 comments provided by the public at the May 13, 1999 public meeting,
 as  well as EPA's  responses  to those comments,  is  provided below.
 Part  I  of  this  section addresses  those community  concerns and
 comments that are non-technical in  nature.   Responses to specific
 legal and technical questions are provided in Part II.  Comments in
 each  Part  are categorized by  relevant topics.

 Part  I  - Summary  and Response to Local Community  Concerns

 Public  Participation Process

 (1)   A  resident  of  the community  requested that EPA review the
 translation of  the  public  meeting.  He was concerned  that the
 facilitator did not  translate word  for word.

     EPA Response:   EPA contracted  to have an interpreter  at the
     public meeting  to  assist with communications  between the
     community  and EPA.  A court reporter also was at the  meeting
     to  record the entire meeting proceedings.  The court reporter
     recorded comments  and  responses of both the public  and the
     interpreter  spoken in Spanish.   An audio recording  of the
     meeting was used to translate into Spanish those comments and
     responses  given in English.   A copy  of the transcript is
     available  for  review in the   information repository  at the
     Major's  Press Office in  Juana  Diaz  and at  the EPA Caribbean
     Division Office located at 1492 Ponce  DeLeon Avenue, Suite
     207, Santuce, Puerto Rico. EPA has reviewed the transcript to
     assure  that  EPA's  Responses  are accurate in addressing the
     comments received.

 (2)   One  citizen  expressed   concern  that  EPA  did not   present
sufficient technical data for citizens to make an  informed  choice.
He proposed that EPA  hold another public meeting in the near future
to present  technical data to  support the decision-making  process
for the preferred alternative.

-------
     EPA Response:  EPA presented the  technical reasons  for the
     proposed change  at  the May  13,  1999 meeting.   The  primary
     technical reasons relate  to  significant  differences  between
     the actual site conditions encountered during construction and
     the conditions which served as basic assumptions in developing
     the 1988 ROD.  The significant  differences are:  1)  increased
     waste volume  and 2)  increased  composition of silt and clay
     materials  (fines)  in  the waste.   EPA  also presented the
     impacts  of  the   changes  in   both   waste  volume   and
     characteristics to the existing ROD remedy as reasons for the
     proposed change to off-site disposal.  EPA feels that  another
     public meeting is not warranted.  However, we are available to
     discuss this further with any citizen who is interested.

Preferred Alternative

(1)  Residents raised questions regarding the permeability of the
clay layer and the permeability of the clean material proposed as
backfill.  They are concerned about  the potential adverse  impacts
of backfilling the excavated area  (West  Field) with clean material
that  is  more permeable  than  the underlying clay layer.   They
reported that clay fill materials,  which are  less permeable and are
comparably priced  to  other imported clean material,  are  readily
available in Juana Diaz.

     EPA Response:  The  1987 Remedial Investigation and additional
     sampling data collected in 1988 indicated the permeability of
     the clay layer to be in the range of  10'4 to 10'5 cm/sec.  EPA
     considered   these   values    as    demonstrating   moderate
     permeability.   The risk-based  cleanup goal  of 39  ppm was
     calculated  assuming  that  the  site would  be developed for
     residential use  at some  future  point  in  time,  considering
     relevant exposure pathways. The cleanup goal does not consider
     placement of a low-permeability  cap  (e.g.  clay,  HDPE liner)
     over soils containing  residual levels  of mercury below this
     concentration.   The residential  exposure  scenario  is more
     conservative than  the scenario associated with  the  current
     industrial/commercial use for the  site.  Any consideration of
     industrial/commercial  future site use  or  installation of a
     protective cap in the risk-based calculation would result in
     a higher cleanup goal.   The 39 ppm cleanup goal is considered
     by EPA to be protective of human health and the environment.

(2)  A citizen suggested that EPA  evaluate the use of a HOPE  cover
system, if material more permeable than the underlying clay  layer
is used as backfill.

     EPA Response: EPA  selected and described in the Declaration
     Statement of EPA's  1988 ROD  the major  components  of the

-------
      selected remedy.   One  of the major components of the selected
      remedy was the  treatment  of material to  below health-based
      levels (39 ppm of mercury)  based on residential use  of the
      property and backfilling the area with treated materials.  The
      area would then be covered with 2 feet of clean imported soil,
      which was considered suitable as an added physical barrier to
      prevent  exposure  to backfill  material  containing  residual
      levels of mercury.   Under the new proposed remedy, the entire
      waste area would be backfilled with clean imported soil. EPA
      believes  that there is insufficient  technical basis to support
      the need  for  an  HDPE cover system,  since,  under the proposed
      remedy,  the entire  excavated area  will  be backfilled  with
      clean imported fill material.

 (3)   The community is  concerned about runoff from  the  excavated
 area during rain events.  In particular,  residents  are  concerned
 that the excavated area  will be subject  to overflow  conditions,
 causing  the migration  of  any remaining residual  contamination.

      EPA Response:  Existing data  from soil  samples collected  at
      neighboring  residential  properties  do  not   support   that
      significant amounts of mercury were  transported  off-site  by
      runoff during historic storm events.  Presently,  runoff  from
      the excavation and  stockpile  areas  is  fully  contained  and
      treated on-site.   Upon completing excavation work,  the  area
      will be backfilled, graded, and vegetated to conform with the
      pre-existing  topography  and  runoff flow characteristics.
      Soils  containing residual mercury concentrations below the 39
      ppm cleanup  goal  will  be  predominantly  located underneath
      several feet of clean fill material and will not be exposed to
      off-site  transport by erosion, runoff, or other mechanism.

 (4) ^  The community is  concerned  about  the potential  for mercury to
infiltrate  into drinkable  ground  water.   They reported that a
municipal supply well  is located 500 feet to the  west of the Site.
Therefore,  the community  questioned why the preferred  alternative
specifies groundwater monitoring for three years and not a longer
period of time.

     EPA  Response:    In  the   1988   ROD,  EPA   included  limited
     groundwater monitoring (i.e.,  for a minimum of three years),
     provided that additional groundwater  investigation  established
     that there was no need for groundwater remediation.   In 1993,
     additional monitoring wells were installed, and groundwater
     sampling  was  performed to  address   this  requirement.   The
     analytical results from groundwater samples did not indicate
     the presence of unacceptable risks associated with groundwater
     exposure.   Therefore,  EPA  believes 3 years of groundwater
     monitoring following the  completion  of the remedial action

-------
     work  (e.g.  off-site disposal  and  backfilling  with clean
     material) to be sufficient for protection of human health and
     the environment. The remedy selected at this Site will allow
     for unlimited use and unrestricted exposure. EPA will oversee
     the removal of contaminated soils and will review  three years
     of ground water sampling results to  insure the protectiveness
     of the remedy.

 (5)  Several residents expressed frustration regarding the length
of time to solve  environmental problems  at  the Site and complete
the cleanup process.  They noted  that 10 years have passed since
the original ROD and wonder how much longer the process will take.

     EPA Response:  EPA plans  to advise  G.E.   to begin  off-site
     removal of waste materials after the ROD Amendment is issued.
     It is hopeful that  all material from the Site will be removed
     by (or before)  the end  of the year.  Groundwater monitoring
     will continue for at least 3 years.   A

Risks to Human Health and the Environment

 (1)  A worker  wanted  to know if mercury could permeate her lungs or
get into her blood.  This worker also reported  finding mercury in
the bottom of her  toilet  bowl  and was concerned about how it got
there.

     EPA Response: The potential for airborne emissions currently
     does  not exist.   In  1997,  G.E.   removed all the  run-off
     materials  from  the  South  Field  and  processed  all  the
     contaminated  materials.    Currently,  all  the  materials  are
     under tarps to  prevent  runoff  and airborne migration.  G.E.
     performed some testing during the remedial investigation and
     confirmatory air monitoring was a major component  of the 1988
     ROD.  Confirmatory  air  monitoring was also performed during
     excavation and  physical treatment work completed from June
     1997 to May 1998 to document  that unacceptable levels of dust
     and mercury did  not become airborne during the course of work.
     Confirmatory air monitoring will resume and continue through
     completion of the remedial action work.

     Ginger M. Rossy, Environmental Quality Board representative,
     is investigating the potential presence  of mercury  in this
     worker's home.

 (2)  A community member reported  anecdotal  material about deaths
and illnesses of people who  lived in Juana  Diaz and were in some
way connected to G.E. He  was concerned that these illnesses might
be related to mercury contamination at G.E.  and was disappointed

-------
 that no  medical personnel  were at  the meeting  to address  his
 concerns.

      EPA Response:  Refer to  EPA's  response to Question No.  9  on
      page 5 .

 (3)   Residents on Calle #2 are worried  that the duration  of  time
 that has passed since Site  discovery may increase  their risks for
 Site-related health  problems.   They are  concerned about  future
 health problems, because of long-term exposure to mercury waste at
 the  G.E.  facility.

      EPA Response:  EPA included re-sampling of soil in residential
      yards  as  a component of  the remedy  selected in the 1988  ROD.
      Residential soil sampling was performed in 1993, and again in
      April  and May  1998.   All results were below  the residential
      remediation goal of  39 ppm. The predominant  exposure  routes
      for this  site are ingestiori and inhalation.  As existing  data
      do  not support  that significant quantities  of mercury  have
      migrated  off-site via  air,  surface  water, or  other transport
      mechanisms,  EPA  believes  that   the  potential  exposure
      associated with occupying neighboring  residences   to   be
      minimal.

 (4)   Residents of Calle #2  stated  that  during Hurricane George,   flB
 their property was  flooded and residual  mud was  left on their  ^^
 property.  They wanted a guarantee that their yards  did not contain
 any  contamination related to  the G.E. Wiring Site.

      EPA Response: Runoff from the excavation and  stockpile areas
      is  fully  contained and treated on-site, preventing off-site
      transport  of  contaminated  materials.    Tarps  blown  off  of
      stockpiled materials  were also replaced and re-secured  by G.E.
     within one month of the  storm.  However, G.E.  indicated that
      it will collect soil  samples from the neighboring residential
     properties.  A notice will  be  sent in advance  of the sampling
     events to ensure that the affected residents will be at home.

Extent of Site Contamination

 (1)   Residents  wanted to  know if mercury contamination is moving
off-site and, if so,  in what direction to determine  the safety  of
their neighborhood.   Also, will  the contamination migrate off-site
in the future?

     EPA Response: Mercury has not migrated  from those areas where
     plastic and other scrap materials  were  deposited.  Surface
     water  runoff  from  the  excavation  and  stockpile  areas   is
     contained  and   treated on-site.    It  will  continue   to   be


                                10

-------
      controlled  until  the  remedial  action  work  is  completed.
      Historic  runoff to  adjacent  residences was  from the  south
      field,  an area of property which  is not contaminated.   EPA
      believes  the  Site  contamination will  not affect  the  adjacent
      or distant  residential  neighborhoods.

 (2)    Residents  wanted   to know  to  what  depth   the   mercury
 contamination  was  found at the Site.

      EPA  Response: Sampling conducted  for the  1988 ROD  detected
      mercury contamination in on-site soils approximately within
      six  inches of  the  surface.   At  depths below  six  inches,
      mercury concentrations were  below health-based levels  and
      approached  background levels.   In the waste  fill  (West Field)
      area, contamination was originally  detected to depths of  about
      4  feet.    However,  excavation depths  up  to  17  feet  were
      required   during   construction    (June   1997)    to  obtain
      confirmatory  soil  sample  results  below the required cleanup
      goal of 39  ppm.

 (3)   A resident  reported  that mercury waste was found off-site at
 an abandoned landfill in Juana Diaz. He questioned what was  being
 done  to investigate other potentially contaminated sites.

      EPA Response:  Carlos O'Niell,  Superfund Branch Chief for  the
      EPA Superfund Division in San Juan,  Puerto Rico explained that
      his office  was aware of this abandoned landfill.   His office
      is in the process  of classifying and  undertaking preliminary
      investigations of landfills in Puerto Rico  (including the  one
      in Juana Diaz) for possible Superfund action.

 (4)  The community  is concerned about long-term impacts of residual
mercury-containing material of up to 39 ppm left at the Site.

      EPA  Response: The  risk-based cleanup  goal of  39  ppm was
      calculated  assuming  that  the  site  would be  developed  for
      residential use  at some future point in  time.   It does not
      consider the  placement  of a low  permeable cap or  clean fill
      material  over soils  containing  residual levels  of mercury
      below this  concentration.  The residential exposure scenario
      is more conservative than the scenario  associated with  the
      current industrial/commercial  use  for the  site.   The 39 ppm
      cleanup goal  is considered by  EPA  to be protective of  human
     health  and  the  environment,  considering  relevant exposure
     pathways.             ,                e

 (5) . A worker at  G.E. reported that he had  buried  mercury waste  on-
Site at his supervisor's direction.  He is concerned  that EPA  did
not find all the mercury at the Site.


                                11

-------
      EPA Response:   Sampling conducted for the  1988  ROD detected
      mercury contamination in on-site soils within six  inches  of
      the  surface.      At  depths  below   six  inches,   mercury
      concentrations  were below health-based levels and approached
      background levels.   In  the  waste fill  (West Field)  area,
      contamination  was originally detected  to depths of  about  4
      feet.   However, excavation depths up to 17 feet were required
      during  construction (June 1997)  to obtain  confirmatory soil
      sample  results below the required cleanup  goal of 39 ppm. EPA
      believes that sufficient sampling and excavation was performed
      at  the  Site to locate and remove all waste materials above  39
      ppm.
Part  II  - Comprehensive Response to Specific Legal and  Technical
Questions

Future Site Liability

 (1)   The community would  like to  know who will  assume  future
liability for the Site.  The community is concerned that  once G.E.
closes  its Juana  Diaz  facility,  G.E.  will no longer  be held
responsible for cleanup at  the  Site.  The community wants  to know
when  G.E.'s responsibility  for  the Site  ends.

      EPA  Response:  EPA, under  the enforcement authorities of the
      Comprehensive  Environmental   Response,  Compensation,  and
      Liability Act (CERCLA), as  amended,  holds the G.E.  Company, as
      owner and operator of the G.E. Wiring Devices Site, liable for
      the  cleanup of the contamination at  the Site.  G.E. must meets
      all   cleanup  conditions  of  the   ROD,   including  long-term
      monitoring.  All of G.E.'s work at  the  Site  will be  performed
      under EPA  oversight.  At some point  in the  future,  once the
      Site has been cleaned up to the satisfaction of EPA,  it may be
      deleted from the National  Priorities List.

Proposed  Remedy

(6)  G.E.  requested that EPA not place restrictions  in  the  Amended
ROD which prevent or pose obstacles to alternative transportation
routes to the  Port  of Ponce  in the event  that the  responsible party
can not obtain  rights  to transport  Site materials across  PRIDCO
property.

     EPA  Response: The ROD Amendment does not state what route is
     to be used to transport the waste to the Port of  Ponce.

(7)  G.E.  requested that EPA not place restrictions  in  the  Amended
ROD which preclude or obstruct .the possible  need  to move  some bags

                                12

-------
of Site material  to an alternative location outside  of the Site
area pending  arrival of  the  barge for  transport to  the United
States.   This  request  is  based  on  the  large  volume  of  Site
materials to be bagged and transported and the relatively limited
space remaining on-Site to maneuver vehicles.

     EPA Response:  To  the extent that G.E. wishes to use such a
     temporary alternative storage location for this purpose, G.E.
     should discuss the location with EPA in advance.
D.  REMAINING CONCERNS

o  Members  of the community raised many health  questions.   They
want  to  know  if residents  who  live  close to the  Site  are
contaminated with mercury.  They want to know if EPA is planning to
do medical tests  of Juana Diaz residents.   If some residents are
found  to  be  ill,   they   want   to  know   if   G.E.   will  take
responsibility.

     EPA Response: The Federal agency responsible for this type of
     investigation is the Agency for Toxic Substances and Disease
     Registry (ATSDR).  There is  a provision in the CERCLA law for
     individual persons or local physicians to petition ATSDR to
     perform a health  assessment if the probable source of exposure
     is  a  release.   Further information  on this procedures  is
     available  from the  ATSDR Regional Office in New  York City.
     Mr.  Arthur  Block,  Regional  ATSDR  representative  can  be
     contacted at  (212)  637-4307.

     Residents  who want  a blood  test for  mercury levels  should
     contact the  local Health Department or their own physicians.
     G.E. officials suggested that anyone  who was tested and had
     high levels of mercury in the blood report that to G.E. on an
     individual basis.
                                13

Dear Ms. Kwan:
This letter is to provide further comments on the project of reference and to emphasize on
questions that were not properly answered during the public meeting of May 13, 1999, in Juana
Diaz. I am writing as a resident of Juana Diaz who is concerned with the safety and health of the
community. My questions or comments are as follow:

 1.     Please make sure that the translation of the proceedings in Juana Diaz are properly
       addressed. EPA provided a translator to facilitate communication with the community
       during the meeting The court reporter was only typing the comments and responses in
       Spanish and used an audio tape recorder for the duration of the meeting. The audio tape
       needs to be reviewed carefully because the translator was doing interpretation instead of
       translation. The translator put things on her own way and did not convey the information
       exactly as it was presented by EPA, GE and the public. It is very important that these
       proceedings be translated correctly since it was obvious that the translator is in favor of
       the project and not a neutral party. She added many comments of her own that were not
       expressed by EPA or GE.

 2.     As expressed and confirmed in the meeting there will be some residual mercury
       contamination (less than 39 ppm) left at the site. We were also informed that because the
       clay layer at the site is 'Very impermeable" there would not be a concern with
       groundwater contamination. No technical data on the permeability of the clays at the site
       was available. GE nor EPA were able to provide a specific answer on the permeability.
       Please provide this information.

 3.     We were informed at the meeting that the excavated area will be filled with permeable
       clean material. There was no justification or explanation provided for this action. EPA and
       GE must justify the rationale for the decision to backfill the excavated area with clean soil
                                                                                . *

       that is more permeable than the underlying clay layer. Even under the Subtitle D
       regulations there is a requirement for installation of a protective cap that has the same or
       lower permeability as the underlying soil. Clay materials are readily available in Juana Diaz
       and the cost of this clay would probably be similar to any other imported clean material.
       EPA should also evaluate the use of an HDPE cover system if more permeable material is
       used as fill material.

4,     Based on the explanation of how the contaminated soil was removed and the presence of
       'Very impermeable" clay one must conclude that at the end there will be a clay bowl filled
       with permeable material. We must also assume that rain water will not migrate away from
       this bowl and will remain there for extended periods of time. What will happen with the
       water when this bowl overflows? Where will it go? Will the water cany mercury
       contamination with it? Is the remaining mercury in a form that it could leach? Please
       explain.

5.     The question on long term liability on GE was asked several times and was never
       answered. Once the project is completed and GE closes the operations in Juana CHaz, what
       happens with the site? Does GE continue to be responsible and liable or is GE released
       from all liability? If after GE is gone there is an environmental incident at or near the site
       involving GE's mercury, who is responsible for the remediation? Please explain.

6.     Please explain and justify the decision to stop ground water monitoring only after three
       years. The only answer we heard at the meeting is that nothing has happened in 30 years
       and nothing should happen in the future. Should there be ground water monitoring  for a
       longer period of time?

7.     I respectfully request that EPA and GE conduct an additional public meeting as soon as
       practicable. The people that  conducted this meeting were not properly prepared for it.
       There should have been immediate answers to the questions that were presented. One
       could tell that the attitude of some of the presenters was not the best one and were
       uncomfortable with the questions being asked. The body language of the gentleman
       representing EPA's Region II in New York said it all. Too many times people asked him
       questions directly and his response would be "Who me? "  or "Why are you asking me? ".
       One did not need to hear what he said, his gestures said it all.

       A new meeting needs to be conducted since the people left the meeting on May 13  feeling
       that the presenters did not know what is going on. No clear answers were provided in
       many cases. Former GE employees at the meeting are not confident that all mercury has
       been removed. We were expected to just accept the general information in good faith. At
       a new  meeting EPA and GE should present technical data that supports the decisions
       made regarding this project.  There should be diagrams depicting the hydro-geology of the
       site and its surroundings, surface water management, ground water analytical data,  and
       analytical data of the contaminated soil remaining onsite. In general the meeting should

       contain sufficient technical information justifying the project so the citizens of Juana Diaz
       feel comfortable with the remedy selected. At this time I am not convinced that this
       remedy is fully protective of the environment and the surrounding community.
I trust that GE and EPA will provide us with the information that we need for our peace of mind

               COMMENTS OF THE GENERAL ELECTRIC COMPANY
         ON THE MARCH 1999 POST-DECISION PROPOSED PLAN FOR THE
        GE WIRING DEVICES SUPERFUND SITE, JUANA DIAZ, PUERTO Rico


The General Electric Company (GE) submits the following comments on the
March 1999 Post-Decision Proposed Plan for the GE Wiring Devices Superfund
Site, Juana Diaz, Puerto Rico. GE strongly supports EPA's recommended
remedy change to allow for the off-site disposal of mercury impacted materials in
a permitted RCRA Subtitle C hazardous waste landfill in the United States.
These comments provide additional details regarding GE's support for this
proposed remedy change.

GE SUPPORTS EPA'S POST-DECISION PROPOSED PLAN
As stated above, GE provides its unequivocal support for EPA's Post-Decision
Proposed Plan.  The change, in remedy recommended by EPA provides the best
balance and is the most suitable remedy with respect to the NCP evaluation
criteria.  It will provide complete protection of human health and the environment,
greater implementability, fewer short-term risks and significantly lower costs as
compared to waste treatment in the GEMEP treatment system with on-site
disposal of treated materials. The chosen remedy satisfies not only the statutory
and regulatory criteria, but also is the best option for the people of Juana Diaz
and Puerto Rico. Off-site disposal will completely remove the contaminated
waste fill materials from the island of Puerto Rico and dispose of them in a
permitted, RCRA Subtitle C landfill in the US. Thus, not only will the
contaminants will be removed from the site, but there will be no backfilling of
treated, iodine and mercury containing residuals as was contemplated under the
original  remedy.


GE SUPPORTS THE LIMITED SCOPE OF THE COMMENT PERIOD
As explained by EPA in the Proposed Plan,

      "EPA is soliciting comment only on a focused portion of the 1988 ROD for
      the site. This change deals only with the off-site disposal of mercury
      impacted material at a permitted RCRA Subtitle C hazardous waste landfill
      on the mainland Uninted States, as an alterative [sic] to  on-site treatment
      using the GEMEP treatment system and subsequent backfill. EPA is not
      proposing to change the established site-specific cleanup goals."

 (Emphasis in original.)

 Commants on Juana Diaz
 Poet-Oacisfon Propo«»d Plan

-------
 GE fully supports the limited purpose and scope of the comment period, since
 the only issue subject to review, and therefore open to public comment, is EPA's
 recommended remedy change to off-site disposal instead of GEMEP treatment.

 Due to recent events at GE's plant in Juana Diaz, there may be comments
 submitted to EPA which seek to open issues unrelated to EPA's proposed
 remedy change (e.g., issues  related to the plant closure, or requests for
 additional investigation activities). Any such comments are not germane to the
 limited purpose of the public comment period, and should not properly be
 considered in EPA's decision-making process. EPA has clearly and carefully
 delineated the limited scope and purpose of the public comment period, and
 comments received which do not relate specifically to the proposed change of
 remedy should not be entertained by  EPA.  GE strongly encourages EPA not to
 address or include such unrelated or irrelevant comments in its deliberations
 relative to this Proposed Plan.
GE BELIEVES NO FURTHER SITE INVESTIGATION IS NECESSARY,
ABSENT NEW INFORMATION ABOUT THE SITE
As mentioned above, some commenters may request additional investigations at
or around the Juana Diaz site, or even at other locations in the Juana Diaz area,
perhaps due to GE's announced plant closing. However, the site was the subject
of numerous investigations in the 1980's and 1990's, and the remedial
investigation was formally completed and approved by EPA in 1993.  In addition,
since commencing on-site remediation in 1997, GE has excavated to the edges
of the waste fill area, and documented, through hundreds of confirmatory
samples, that the residential cleanup standard has been achieved. Therefore, in
the absence of new information dictating a need to reopen past investigations,
GE hereby states its opposition to conducting any additional investigations on, at
or around the Site.

GE NOTES THAT THE PROPOSED PLAN WILL RESULT IN LESS RESIDUAL
MERCURY-CONTAINING MATERIAL AT THE SITE
GE supports the Proposed Plan and the removal and off-site disposal of Site
waste materials since that will result in less residual mercury-containing material
remaining at the site. While both the GEMEP remedy and the proposed off-site
remedy would reduce mercury concentrations at the site to the residential
cleanup standard of 39 ppm, the off-site remedy will nmov* all of the washed,
oversized material from the site, whereas the GEMEP remedy would have this
material - which still contains low concentrations of mercury - backfilled on-site.
In addition, the off-site remedy will completely remove the approximately 10,000
tons of untreated fines from the site, whereas the GEMEP remedy would also
have had this material backfilled on-site following treatment, when it also would
contain low concentrations of mercury and high concentrations of iodide.

Comments on Juana Diaz
Post-Decision Proposed Plan

-------
GE RECOMMENDS FLEXIBILITY IN THE PROPOSED PLAN TO ALLOW FOR
EFFECTIVE IMPLEMENTATION OF THE REMEDY
As GE begins preparations for implementation of the remedy, it has become
apparent that a reasonable degree of flexibility in the logistics for completing the
remedy will be necessary.  Consequently, GE recommends that any change to
the ROD allow sufficient flexibility for alternative logistical requirements, if
necessary. For example, GE is currently negotiating with its neighbor, PRIDCO,
to obtain rights to transport Site materials across a portion of PRIDCO's property
to access an appropriate transportation route to the Port of Ponce. This right of
access route ren.i.ns to be negotiated. If GE is unsuccessful in obtaining access
rights to PRIDCO property, it may be necessary to follow an alternative route
from the GE Site. Any amendment to the ROD should not prevent or pose
obstacles to such alternative routes.

In addition, due to the large volume of site materials to be bagged and
transported and the relatively limited amount of space remaining on-srte to
maneuver vehicles, GE's contractor, Safety-Kteen, has suggested that it may be
necessary to move some bagged material to an alternative location pending
arrival of the barge for transport to the US. This potential eventuality also should
not be precluded or obstructed by any amendment to the ROD.

In summary, GE strongly supports EPA's recommended decision in the Post-
Decision Proposed Plan, and provides these comments in the spirit of
cooperation and a desire to have the off-site remedy completed as smoothly and
efficiently as possible.  If you have any questions regarding these comments,
please contact any of the undersigned.

 RE:   FOCUSED FEASIBILITY STUDY (FFS)
       G.E. WIRING DEVICES, NOVEMBER, 1998

 Dear Mr. Hauptman:

 The two remedial alternatives presented by GE for the completion of the remedy at General Electric
 Company Wiring Devices Superfund Site in Juana Diaz, Puerto Rico are the following:

       I.     GE Mercury Extraction Process (GEMEP)
       2.     Off-Site Disposal in a Subtitle C Landfill on Mainland United States

 After a thorough evaluation of the alternatives suggested, the Puerto Rico Environmental Quality
 Board (PREQB) does not agree with the GEMEP alternatives for the following reasons:

       •      High costs
       •      Delays
             Plugged Pumps,  Eroded Pipes, and Inadequate Mixing
       •      Reduced Clay Removal
       •      Poor Filter Press Performance
             Overloaded Polishing Filters
             Plugged Iron Filing Bed
       •      Ineffective Mercury Removal
             Incomplete Iron Removal
       •      Incomplete Iodide Oxidation (Iodine Loss)
       •      Inadequate Recovery of Iodine Crystals (Iodine Loss)
      •      Personnel Exposure to Process Chemicals

Additionally, this alternative will require 21 months or more to complete along with a long term
monitoring.

 On the contrary, the Off-Site Disposal in a Subtitle C Landfill on Mainland US alternative is favored
 by the PREQB because it only requires 6 months or so to complete, long term monitoring is not
 required, relatively low costs,  and finally, as indicated on page 3-18 of the Focused Feasibility
 Study (FFS) of April, 1998, off-site transportation of contaminated material represents only a
 minimal risk.

                        RECORD OF DECISION


 SITE  NAME AND LOCATION

 GE Wiring Devices, Juana Diaz, Puerto Rico

 STATEMENT OF BASIS AND PURPOSE

 This  decision document presents the selected remedial action for
 the GE Wiring Devices  Site, in Juana Diai, Puerto Rico, developed
 in accordance with CERCLA, as amended by SARA, and, to the extent
 practicable, the National Contingency Plan.  This decision is
 based on the administrative record for this site.  The attached
 index identifies the items that comprise the administrative
 record upon which the  selection of the remedial action is based.

 The Commonwealth of Puerto Rico has concurred in the selected
 remedy.

 DESCRIPTION OF THE SELECTION REMEDY

 The remedial action would remediate the waste-fill area, perched
 water, and the mercury contaminated near-surface soils to levels
 which would be protective of public health.  With respect to
 contaminated soils downgradient of the waste-fill area, since the
 mercury is primarily in the upper six inches of soil, the remedial
 action would include remediation of the upper six inches of soil
 at a minimum.  Since groundwater data is limited, further investi-
 gation and monitoring will be conducted during design to determine
 the extent of groundwater contamination.

The major components of this remedial action are:

 0 Further treatability studies during remedial design to insure
  the implementability of hydrometallurgical processes, as well
  as continued study of other treatment alternatives.

 0 On-site hydrometallurgical treatment of the waste-fill materials
  (approximately 4000 cubic yards),  perched water (approximately
  1/2 million gallons) and contaminated near surface soils
  (approximatedly 1500 cubic yards);

 0 Treatment of the material to below health-based levels and
  back-filling the waste fill area with the treated materials.
  This area will then be covered with two feet of clean soil.

0 Additional investigation of the groundwater to determine the
  extent of groundwater contamination;

-------
                               - 2 -
   Limited groundwater monitoring (i.e. for a minimum of three
   years), provided that the additional groundwater investigation
   establishes that there is no need for groundwater remediation-
   and  •                                                  •      '

 0 Confirmatory air monitoring and re-sampling of soil in residential
 DECLARATION

 Consistent with the Comprehensive Environmental Response,  Com-
 pensation, and Liability Act of 1980 as amended by the Superfund
 Amendments and Reauthorization Act of 1986,  and the National Oil
 and  Hazardous Substances Pollution Contingency Plan,  40 CFR Part
 300,  I  have determined that the selected remedy is protective of
 human health and  the environment, attains Federal  and State
 requirements that are applicable or relevant and appropriate for
 this  remedial action, and is cost-effective.   This remedy  satisfies
 555»!ia *to?y Preference for remedies that employ  treatment that
 reduces toxicity,  mobility,  or volume as a principal  element and
 utilizes permanent solutions and alternative  treatment (or resource
 recovery)  technologies to the maximum extent  practicable.

 Because this remedy  will not result in hazardous substances
 remaining  on-site  above  health-based  levels,  the five-year remedial
 action  review will not apply to this  action.                ™eaiax

£ite  Background


The G.E- Wiring Devices Site is located in the south central part
of the  Island in Juana Diaz, Puerto Rico.  The Site is northeast of
Ponce,  close to the intersection ot Routes 14 and 149 (See, Figures
1 and 2).  The General Electric Company (G.L.) operates a wiring
devices plant at this site that occupies approximately 5 acres ot
land.   The property was originally leased from the Puerto Rico
Industrial Development Company (PRIDCO)j the property is now owned
by G.E.

The source of contamination at the site is the waste-fill area
where defective parts from silent mercury switches were discarded.
These switches were assembled at the plant from 1957 until 1969.
Each  switch contained a hermetically sealed stainless steel button
that  encased a ceramic core, containing elemental mercury.  Off-
specification buttons were generally broken to reclaim the mercury.
The steel button shells, with residual mercury and ceramic cores,
were then discarded in the on-site waste-fill (pile) area where
other defective switch parts and plastic scraps were also discarded.
Based on test pit excavations, the waste-fill area is approximately
1 to 4  feet thick 110 feet wide and 440 feet long.  As calculated
in the  Remedial Investigation, it is probable that roughly halt a
ton of  mercury was discarded in the waste-fill area, based on
mercury switch production and rejection documentation.

Several residences are located approximately 400 feet south ot the
waste-fill area.  A concrete retaining wall and fence exist between
the site and the residences.  Groundwater in the area is used as a
source of potable water.  A public supply well is located approximately
1500 feet west of the waste-fill area.

Site History

The site was proposed for inclusion to the National Priorities list
in December 1982.   The original scoring was changed in June 1983
based on public comment.  A Remedial Investigation and a Feasibility
Study (RI and FS)  were conducted by the General Electric Company
(GE) through its contractor Law Environmental Services at the G.E.  .
Wiring  Devices Site.  These activities were performed pursuant to
an Administrative Consent Order II-CEkCLA-30301 dated January 16,
1984.   An RI report was submitted to the U.S. Environmental Protection
Agency  for review in October 1986.  EPA determined that additional
investigation was  necessary in order to further define the nature
and extent of contamination at the Site.  A Supplemental RI and an
FS report were submitted to EPA in draft in October and November
1987,  respectively.  The data collected during the RI were reviewed
for conformance with EPA data validation requirements.  Subsequently,
EPA concluded that the quality of the data did not meet EPA specifi-
cations.  Accordingly, in August 1986 £PA in cooperation with G.E.,
collected additional samples to complete the RI activities.  Maps
depicting sampling locations and a summary of results are presented
in figure 3 and 4 and Table 1, respectively.

-------
                                - 2 -
  The draft PS did not fully evaluate treatment alternatives tor
  remediation of  the Site and did not fully conform with the criteria
  set forth in the Comprehensive Environmental Response, Compensation
  and Liability Act of 1980, as amended (CtRCLA).  As a result, EPA
  entered into an agreement with the U.S. Bureau of Mines to evaluate
  additional treatment technologies.  The objectives of this evaluation
  were to identify and assess additional treatment technologies which,
  if implemented, could result in achieving a more permanent remedy by
 reducing the toxicity, mobility or volume ot the contaminant.  EPA
 then prepared an PS Addendum to further comply with CERCLA.

 Community Relations

 EPA has kept the local citizens and officials advised throughout
 the Superfund process.  Several public meetings were held in Juana
 Diaz to discuss site developments.  Specifically, a public meeting
 was held in February 1984 to discuss the provisions of the
 Administrative Order,  as well as,  to receive and respond to comments
 concerning the site.   In April 1987, a public meeting was held to
 solicit comments on and discuss the findings of the RI.   In September
 1988,  a public meeting was held to discuss and receive comments on
 the studies  and EPA's  proposed remedial action plan.   Questions ana
 comments with  their  corresponding  responses are summarized in the
 attached Responsiveness Summary.

 Site Characteristics

 A silty clay  to clayey  silt unit exists immediately beneath the
 waste-fill materials.   This unit is believed to  be  continuous as
 evidenced  by  its presence  at 103 test  pit  excavations.   The unit
 appears to be  from  1 to 4  feet  thick based on monitoring well logs.
 The permeability of  the unit is in the range ot  6.0 x 10-4 to
 8.0 x  10~5.  However, roots were observed  in the shallow  soils
 which  could increase the permeability  of  the soil by  developing
 channels through which  contaminated leachate could  flow.   The silty
 clay unit overlies  the  holocene alluvial sediments  deposited  by the
 Rio Jacaguas River as illustrated  schemetically  in  Figures 5  and 6.
 This alluvium  is divided into  four strata  (See Figure 6);  a  very
 silty  fine to coarse sand,  a sandy clayey  silt,  a silty  sand  and a
 sand and gravel  unit.   Results  of  a resistivity  survey  indicate low
 resistivities at depths  of  up to 12 feet in  the  central and western
 portions of the  waste-fill.  This  may  be indicative  that  a zone ot
high moisture content is present in the alluvial  sands which  underlie
 the clay stratum  in some areas  of  the  waste-fill.

 This moisture could be the  result  of slow  downward migration  of
perched water through the  silty clay stratum.  Groundwater was
encountered within the alluvial sand and gravel  formation  at  a
depth of about 45 feet below the existing  grade.  The  groundwater
potentiometric gradient has been reported  to be on the order  of 0-01
to 0.006 ft./ft., with a groundwater flow  direction to the west
towards the Rio Jacaguas River.

-------
                                 - 3 -


  Perched water accumulates within the waste-fill area as a* result of
  precipitation/recharge; the perched water generally consists of a
  few  feet of water perched above the top of the above-referenced
  clay layer.   The depth to the  top of the perched water is approx-
  imately 2 feet below the existing grade at the waste-fill surface.

  The  primary route for migration of mercury appears to be through
  surface runoff from the waste-fill area.  This results in the
  contamination of surface soils to the south of the waste-fill area
  (downgradient).  The waste-fill area formerly received storm-
 water runoff directly from the plant area, the runoff has since
 been diverted by the construction of a drain pipe in 1982.   The
 potential for vaporization of the mercury also exists.  In addition,
 as stated above,  the permeability of the clay underlying the fill
 area is moderate and roots were observed in these soils.  Also, the
 resistivity data suggests  that the migration of perched water
 through the silty clay stratum has occurred.

 Furthermore,  groundwater sampling suggests that the mercury has
 migrated to the water table.   The highest concentration of  mercury
 in the deeper  groundwater  (i.e., 2.2 ppb)  is slightly above the
 Maximum Contaminant  Level  (2.0 ppb).   However,  this result  was
 obtained only  in  one sampling round approximately 50 feet away  from
 the waste-fill  area.   The  location,  number and depth of monitoring
 wells are  inadequate to fully characterize the  extent  of groundwater
 contamination  at  the site.  Therefore,  further  investigation of the
 groundwater  will  be  conducted during  design of  the remedial  action
 to determine the  nature and extent  of groundwater contamination.
 This  work will  include installation of  additional groundwater
 monitoring  wells  and groundwater sampling.   Additional remedial
 action may be necessary pending  the results  of  this  investigation.

 The data collected during  supplemental  sampling indicates that
 mercury  was  found in  the following  areas:

      1)  In an on-site surficial waste-fill  (pile)  area.  This  area
      is approximately 110  feet in width and  440 feet  in  length  and
      about 4 feet deep, containing  roughly  4000 cubic  yards  of
      contaminated waste.  The highest concentration observed  in the
      waste-fill area  is 1400 parts per million  (ppm) 'of  mercury.

      2)  In perched groundwater  within the waste-fill  area.   Approx-
      imately 1/2 million gallons of contaminated  water  is found at
      shallow depths  (approximately 2 feet below the ground surface).
      The highest concentration of mercury detected  in  the perched
      water is 6.917 ppm.

      3)  In soils found approximately within the  upper six  inches
      of the surface   (hereinafter referred to as  "near-surface


    In general,  mercury concentrations decreased with depth in these
soils.  Ac depths below six inches mercury concentrations were
below health-based levels  and approached background levels.

                                - 4 -
      soils") in an area which is in the direction of surface water
      runoff from the waste-fill area (i.e., south or downgradient).
      Since the number of valid soil samples is limited, the volume of
      contaminated soil has been calculated by multiplying the
      estimated areal extent of contamination  by a depth of six
      inches.  The volume of contaminated soil has been estimated at
      1500 cubic yards using this conservative approach.  The highest
      concentration of mercury detected in soils is 61.630 ppm.


 Site Risks

 An endangerment assessment was conducted to determine exposure
 routes  and concentrations of mercury which may pose a risk to human
 health.  The endangerment assessment evaluated the baseline public
 health  risks associated with the site in the absence of any remedial
 action.  The primary exposure routes of concern which were evaluated
 were ingestion of contaminated soils/waste-fill material and inhalation
 of mercury vapors.    Data gathered for  the EPA Mercury Health Effect
 Update  (1984)  indicates that diet and ambient air inhalation yield
 an intake of methyl  mercury that is 18% of the Reference Dose (the
 Reference dose  is 0..0003 mg/kg-day).  Therefore,  in evaluating  the
 risks posed by  ingestion of contaminated soils/waste-fill material,
 the daily intake  which  would result in  exceedence of 82% of  the
 reference dose  was calculated using various assumptions.  This—-,s
 analysis  indicates that mercury  concentrations in excess of  BB.8/ppm
 may result in exceeding the reference dose.   The  sampling   ^—^
 data indicates  that  the concentrations  of  mercury in the soils  and
 waste-fill area exceed  this value.   In  addition,  air modelling  was
 conducted to predict  the  concentration  of  mercury vapors which
 could be  emitted  given  the  concentration of  mercury detected in
 the  soils and waste-fill  materiaLa-r-->O?he modelling showed that
 soil concentrations  in  excess  of(l6.4\ppm  may cause the EPA
 National  Emission Standard  for a  Haxa-tdous Air Pollutant (NESHAP)
 to be exceeded.  The  NESHAP for  mercury is  1  ug/m3.   The
 modelling also .indicates  that  there  is  a potential  risk associated
 with vaporization of  mercury from the waste-fill  area.   Additional
 air  sampling will be  conducted during the design  to verify
 whether the NESHAP is being exceeded.


 Scope of  Response Action

The  objectives of the remedial action are, in  general,  to achieve
clean-up  levels of mercury  in  the waste-fill area  (including perched
water) and downgradient soils  which: adequately protect human'health

.^ -^ _l___^^__,
  As discussed previously,  the groundwater database  for the  site      4fe
  must be supplemented in order to fully characterize ground-         IV
  water  contamination.  Therefore, a supplemental groundwater
  investigation will be conducted during design.  Consequently,
  the risks posed by groundwater contamination will be  evaluated
  after  completion of the investigation.

 and the environment/ are cost-effective/ and utilize permanent
 solutions and alternative treatment technologies (e.g./ those which
 reduce the toxcity, mobility or volume of a hazardous substance)
 to the maximum extent practicable.   The remedial action must also
 substantively comply with applicable or relevant and appropriate
 requirements.

 The remedial action would remediate the vaste-fill area and the
 mercury contaminated near-surface soils to levels which would be
 protective of public health.   With  respect to contaminated  soils
 downgradient of the waste-fill area, since the mercury is primarily
 in the upper six inches of soil,  the remedial action would  include
 remediation of the  upper six  inches of soil,  at a minimum.   This
 conservative approach should  ensure the removal of all soil with
 mercury concentrations above  health-based levels.   Since ground-
 water  data is limited, further investigation  and monitoring will  be
 conducted  during design to determine the  extent of groundwater
 contamination. •'•••••

 Description of Alternatives

 A  total  of nine  remedial  alternatives  were identified  in the
 Feasibility Study and  addendum for  dealing with the mercury
 contamination at the G.E.  Wiring  Devices  site.   They were numbered
 as  follows:

     1  No  Action
    *2  Cap with  Extraction Wells
     3  Fixation
     4  Cap,  Cut-off  Walls  and  Extraction  Wells
    *5  Separate  Waste  by Mechanical  Screening
    *5a Alternative  5 with  Only Off-site Disposal
    *6  Separate  Wastes  by  Mechanical Screening  and  Washing
    *6a Alternative  6 with  Only Off-site Disposal
     7  Excavation and  Redisposal On-site
     7a Alternative  7 with  Off-site  Disposal
     8  Thermal Treatment
     9  Hydrometallurgical  Treatment

The six alternatives that  EPA considered  in greatest detail are
summarized below.   Each alternative  addresses remediation of approx-
imately 4000 cubic yards of waste-fill material, 1/2 million gallons
of contaminated  perched water and 1500 cubic yards  of contaminated
near-surface soils.
  Although evaluated in the FS, Alternative 2 was eliminated
  because it is ineffective compared to Alternative 4.
  Alternatives 5, 5a,  6 and 6a were eliminated based on technical
  feasibility since the waste is not amenable to physical
  separation.

-------
                               - 6 -


  Alternative 1
  NO ACTION - This alternative is used as a baseline for comparing
  other alternatives and consists of leaving the site as it  is.  No
  response actions would be implemented other than long-term monitor-
  ing which would include a minimum of three wells hydraulicallv
  downgradient of the waste-fill area and three  wells south  of the
  waste-fill area (i.e.,  in the area where contaminated  soils have
  been detected).  Because the waste is left on-site EPA must
  review the remedial action no less than each 5  years after the
  initiation of such action to ensure that the remedial  action
  remains  protective of public health and the  environment.  This
         of the remedial  action is  required under Section 121 of
           Land use restrictions  would be required.
 Alternative  3

 FIXATION  -   This alternative consists of physically fixing the
 waste with cenent to resist erosion.  Trenches would be duq
 within the waste-fill area to facilitate drainage towards a sump.
 The sump, along with a leachate extraction well, would be installed
 a* *he downgradient end of the waste-fill area.  Perched water
 within the waste-fill area would be pumped, via one extraction
 well and would be pretreated on-site prior to disposal at a
 publically owned treatment works (POTW).  Treatment would
 consist of filtration then carbon adsorption.  Contaminated
 near-surface soils will be excavated and consolidated in the       Jfr
 waste-fill area.  The soils and waste-fill material would then be  W
 mixed with cement to blend into an aggregate solid waste.   A soil
 cap would be placed over the waste-fill area.  This alternative
 does not  require any long-term pumping of leachate.   Long-term
 groundwater monitoring would be conducted to verify the long-term
 performance of  this  remedial alternative.   Such monitoring would
 be consistent with the description provided in Alternative 1,  the
 No Action Alternative.   In addition,  the remedial  action would be
 reviewed  every  five  years  as with Alternative 1.   Land use restrict-
 ions  would be required  for this  alternative in order  to ensure
 that  the  integrity of  the  remedial  action or the function  of any
 ot the monitoring  systems  are not disturbed where  contaminated
 materials  are left on  site.

 Alternative 4

 CAP, CUT-OFF  WALL WITH EXTRACTION WELLS  -  This alternative  consists
 of providing  a multilayer  impervious cap,  slurry wall  and  leachate
 collection system.   Trenches would  be dug  within the waste-fill
 area to facilitate drainage towards a sump.  The sump  with  a
 leachate extraction  well would be installed  at  the downgradient
 end of the waste-fill area.  Perched water within the waste-fill
 area would be pumped, via  one extraction well  and would  be  pre-
 treated on-site prior to disposal at a POTW.  Contaminated near-
 surface soils will be excavated and consolidated in the  waste-fill  A.
 area.  The cap and slurry wall would then be installed.  The cap    •!
would be constructed of clay underlain by a  synthetic membrane

-------

  liner to further reduce infiltration,  sand  to promote drainage,
  and top soil to promote vegetation and mininmize  erosion.  The
  slurry wall would surround the landfill and would be keyed into
  fjf.??1 stratum-   Pumping and treatment of leachate from the
  landfill would  be conducted on an  as-needed basis and may be
  required for an indefinite period  of time.  The treatment system
  constructed for the treatment  of perched water would be used to
  treat the leachate and  -ould consist of filtration followed by
  carbon adsorption.   The treated leachate would also be disposed
  of  at a POTW.   Long-term groundwater monitoring,  consistent with
  the description provided in Alternative 1,  will be conducted
  to  assess  the long-term effectiveness  of this remedial alternative
  Since  waste  remains  on-site above health-based levels the remedial
  action must  be  reviewed avery  five years as with Alternative 1.
  Land  use restrictions would be  required  for this alternative.
 EXCAVATION AND CONSOLIDATION ON-SITE - This alternative proposes to
 rencve the contaminated material from the site and consolidate them
 in a newly constructed on-site landfill to be located in the area
 of contamination.  The perched water would be pumped from the
 waste-fill area in the same manner as in Alternative 4.  The waste-
 fill area would then be excavated and an impervious liner (i.e.,
 with a 10-' permeability) would be placed on top of the clay
 stratum.   The waste and contaminated soils would then be placed on
 the liner.   A cap,  slurry wall and leachate collection system
 would be  installed as with the preceding alternative.   Pump'ng
 and treatment of leachate from the landfill would be conducted on
 an as-needed basis and may be required for an indefinite period
 of time.   The treatment system used for treating the perched
 water would be used to treat the leachate and would consist  of
 filtration  followed by carbon adsorption.   The treated leachate
 would also  be disposed of at a POTW.   Long-term groundwater
 monitoring,  consistent with the description provided in Alternative
 1,  will be  conducted to assess the long-term effectiveness of
 this  remedial alternative.   Since  waste remains  on-site above
 health-based levels,  the remedial  action must be reviewed every
 five  years  as with  Alternative 1.   Land use restrictions would  be
 required  for this alternative.

 Alternative  7a

 ALTERNATIVE  7 WITH  OFF-SITE DISPOSAL -  This  alternative is the
 same  as Alternative  7  except  that  the soils  and  waste  from the
 waste-fill area would  be  shipped to a RCRA  Subtitle  C  hazardous
 waste landfill in the  mainland  U.S., since  there are currently
 no permitted  Subtitle  C  disposal facilities  in Puerto  Rico.

 Confirmatory  sampling  would be  necessary to  verify that
contaminated  materials left on  site were below health-based  levels
 If further investigation of the groundwater  confirms that there
 is no significant health risked posed by groundwater,  then limited
long term monitoring would be conducted  (i.e., a minimum of three

-------
                               -  3 -                              ,

  years  consistent with the  description provided in Alternative 1).
  Land use restrictions would  not be  required.

  Alternative  8

  THERMAL TREATMENT - This alternative proposes to treat the contami-
  nated  material  on-site by  heating the waste until all the mercury
  is  vaporized.   Mercury has a  relatively low boiling point (375*C)
  and  most of  its compounds  decompose into metallic mercury readily
  upon heating.   The mercury could  then be recovered and recycled.
  This material may have to  be  reclaimed in the mainland since
  currently there are no facilities on the island which recover
  mercury.  There is a  range of temperatures at which a thermal
  treatment system for  recovery of mercury from the waste could be
  operated.  At the high end of the range is incineration of the
  waste.   Since a high percentage of mercury is adsorbed to the
 plastic materials  in the waste-fill area,  the low end of the range
 would be a temperature at which the mercury could be recovered
  from the plastic  without decomposing the plastic (between 375 *C
 and 850'C).   The  optimal operating temparature of the thermal
 treatment system  would be evaluated during design.   Another
 potential thermal treatment option is vacuum distillation.   In
 this process the waste would also be heated to drive-off the
 mercury and a vacuum would be applied to extract the mercury out
 of the  plastic.   With either type of thermal treatment the mercury
 vapor would be trapped and condensed.   If  selected,  this process
 would be designed to achieve levels  protective of public health.
 The residue from the process would be disposed of on-site in the
 former  waste-fill area.   A two foot  soil cap would  then  be placed
 over the former  waste-fill area.  Since  the source  of  contamination
 would be treated and the  residuals left  on-site would  be below
 health-based levels,  no land use restrictions would  be necessary.
 In addition,  if  further  investigation  reveals no  significant
 ground  water contamination, then only  limited groundwater monitoring
 would be conducted with  this  alternative (i.e., a minimum of  three
 years consistent with  the  description  provided in Alternative 1).

 Alternative  9:
HYDROMSTALLURGICAL TREATMENT  - This  type  of  treatment would be
utilized  to  treat  the  contaminated near-surface soil, perched
water and waste-fill materials.  This alternative  involves putting
the -nercury  into solution by  using a leaching agent such as
cyanide,  hypochlorite  or nitric acid.  The mercury would then be
recovered from the  aqueous solution by using various metallurgical
techniques such as  filtration and cementation/ precipitation.
The waste would be  mixed with the leaching agent until 'the desired
level of  mercury is extracted from the waste and put into solution,
The process  stream  from the leaching stage would then be filtered.
The residue  from filtering *ould be disposed of in the former
waste-fill area and capped with soil as in Alternative 8.  The
process would  be designed to  achieve treatment of  mercury from
the waste to below health-based levels (i.e., less then 16.4 ppm).
Since it  is  anticipated that  the treatment process could attain
treatment of mercury to below acceptable levels,  the actual

-------
                                - 9 -


   performance standard for the treatment process would be determined
   by the maximum removal efficiency associated with the technology
   with due consideration to the corresponding incremental- cost
   involved in achieving further removal.  The mercury-laden liquid
   from the filtering stage would then be subjected to cementation
   or precipitation to remove the mercury.  This result is achieved
   by bringing the liquid in contact with materials such as stainless
   steel, zinc, copper or aluminum.

   During cementation,  the mercury is exchanged with the metal and
   precipitated out.   The liquid would then be recycled back through
   the process.  It is anticipated that only one batch of leaching
   agent would be needed.  Upon completion of the process,  the
   remaining liquid would be treated on-site prior to discharge to a
   POTW.  Further treatability studies will be conducted during
   design to optimize the treatment  process.   The process would be
   designed to meet or exceed levels protective of public health.
   Since the source of  contamination would be treated and the residuals
   left on-site would be below health-based levels,  no land use
   restrictions would be necessary.   In addition,  if further investi-
   gation reveals no  significant ground water contamination, then
   only limited groundwater monitoring would be conducted with this
   alternative (i.e.,  a minimum of three years consistent with the
   description provided in Alternative 1).

 Analysis of Remedial Action Alternatives

 The  remedial  action  alternatives  described above,  were then
 evaluated in  accordance with the  requirements of the National
 Contingency Plan (NCP)  and the Comprehensive Environmental  Response,
 Compensation  and Liability Act as amended by the Superfund  Amendments
 and  Reauthorization  Act of 1986 (CERCLA).   Nine  criteria relating
 directly to the  factors mandated  in Section  121  of  CERCLA,  including
 subsection  121(b)(1)(A-G)  and  EPA's Interim  Guidance on  Selection
 of Remedy (December  24,  1986 and  July 24,  1987)  were utilized for
 this evaluation  and  are as follows:

            Protection  of  human health and the environment
            Compliance  with  applicable or  relevant  and appropriate
            requirements  (ARARs)
            Long-term effectiveness and permanence
            Reduction of  toxicity,  mobility  or volume
            Short term  effectiveness
            Implementabi1ity
            Cost
            Community acceptance
            State acceptance

PROTECTiqN_qF_HlMAN__HEALTH AND THE  ENVIRONMENT

Protection of human health and the  environment is the  central.
mandate of CERCLA.  Protection  is achieved primarily by  taking
appropriate action to ensure that there will be no  unacceptable
risks to human health or the environment.

-------
                                - 10 -
 Except for the No Action Alternative each of the alternatives
 affords adequate protection of public health and the environment.*
 Alternatives 4 and 7 afford protection by providing a combination
 of engineering (cap, slurry wall, etc.) and institutional  controls
 (land use restrictions).  Alternative 3 provides protection by
 fixing the waste which limits the availability of mercury  for human
 exposure.  Alternative 7 provides protection by removing the contam-
 inated material from the site.  Alternatives 8 and 9 provide protection
 through treatment of the waste which reduces the concentration of
 mercury down to or below health-based levels.

 COMPLIANCE WITH ARARs

 Section 121(d)  of CERCLA requires that remedial actions comply with
 all  applicable  or relevant and appropriate Federal and State require-
 ments for the hazardous substances,  pollutants or contaminants that
 are  present on  site, as well  as any  action-specific and locational
 requirements.

 Applicable requirements refer to those situations where the specific
 legal or regulatory jurisdictional prerequisites of a particular
 statute or regulation are met.   Relevant and appropriate requirements
 apply only to on site portions of remedial actions and are  those     jBk
 which were developed to address problems similar to those  encountered^P
 at a  site.   A relevant and appropriate requirement must be  complied
 with  to the same extent as if it were applicable.

 With  respect to requirements  which are chemical-specific for mercury
 contaminated soil  and debris,  there  are no applicable or relevant
 and appropriate requirements  (ARARs).**  Therefore, an Endangerment
 Assessment   was performed to  determine the concentration of mercury
 that  would  result  in an acceptable risk level  if left on-site.  All
 of the  alternatives  evaluated,  with  the exception  of  the No Action
 Alternative, will  result in site remediation which would minimize
 exposure  to mercury  concentrations above  acceptable health-based
 levels.   Air modelling indicates that 16.4 ppm is  the lowest con-
 centration  of mercury which would pose a  risk  to public health.
   Note, any potential risks posed by groundwater contamination
will be addressed following the supplemental  investigation to be
conducted during design.

   Note, there are chemical specific ARARs for groundwater contarnin
ated with mercury (i.e., the Maximum Contaminant Level promulgated
pursuant to the Safe Drinking Water Act), however, the risks posed
by groundwater contamination will be addressed using the data
obtained during the additional groundwater investigation to be
conducted during the design of the remedial action.

-------
                             <   - 11 -

 Air sampling will be conducted during remedial  design to confirm
 the results of this air modelling.   If the monitoring verifies this
 value,  then 16 ppm will be  the cleanup level  for  remedial action.
 However,  if the air monitoring indicates that there are no levels
 exceeding the NESHAP, then  21  ppm,  the lowest concentration of
 mercury which would pose a  risk to  public health  through ingestion,
 will be used as the site cleanup level.

 Potential action-specific ARARs were identified for the remedial
 alternatives which were evaluated.   A discussion  of such potential
 ARARs and the rationale for determining  whether the requirement
 should  be considered as an  actual ARAR is presented below.

 With respect to locational  ARARs, the site appears  to be in close
 proximity to known historic sites.   A Stage IA  survey will  be
 conducted during  design to  identify any  potential undocumented
 resources on or eligible for nomination  to the  National  Register
 of  Historic Places.

 For the alternatives which  involve  landfill closure (Alternatives 4
 and 7)  the RCRA closure regulations  would be  relevant and appropriate.
 For Alternatives  4 and  7, the  landfill would  be closed in conformance
 with  40 CFR Part  264, Subpart  N which describes the closure  requirements
 for a RCRA hazardous waste  landfill.   Alternatives  3,  8  and  9  which
 treat the  contaminated  materials to  below health-based levels  would
 be  closed  consistent with a RCRA clean closure  regulations.

 For  alternatives  which  involve  discharge  of perched water to a
 POTW, guidance  from  the EPA memorandum entitled "Discharge  of
 Wastewater  from CERCLA  Sites into POTWs"  would  be used,  as  well as
 the  permit  requirements for the specific  POTW.  The guidance would
 preclude  the use  of  a POTW  which is  out of compliance  with  its
 permit  requirements.  Accordingly, the treated  perched water may
 only be discharged to a  POTW that is  permitted  to accept such  wastes
 and  is  operating  in  compliance  with  that  permit.  The  on-site
 pretreatment must  achieve the levels  set  forth  in the  POTW's permits.

 The applicablity,  relevance  and  appropriateness of  the Land  Disposal
 Restrictions  (LDRs)  under RCRA  were considered  with  respect  to the
 remedial  alternatives evaluated.  The LDRs would not  be  applicable
 since the contaminated  materials are  not hazardous  wastes.  With
 respect to  relevancy and appropriateness, currently  the  only LDR
 treatment standards which have been promulgated are  for  non-soil
 and debris  wastes.  Treatment standards for soil and  debris wastes
are currently being developed by EPA.  In the interim, because there
are no  treatment standards  for  soil and debris  wastes  and since
the contaminated materials  found at the site are not sufficiently
similar to  those for which  such standards exist, the £DRs are  not
considered relevant and appropriate.

-------
                                - 12 -


 Section 121(d)(3) of CERCLA requires that if a remedial action
 involves off-site disposal at a RCRA hazardous waste landfill,
 such disposal may only take place if releases are not occuring
 from the unit which would receive the waste and any other releases
 from the disposal facility are controlled under a corrective action
 pursuant to RCRA.  Alternative 7a, which provides for off-site
 disposal, will comply with this requirement.

 While permits are not required for on-site remedial actions at
 Superfund sites, any on-site remedial action must meet the
 substantive requirements of the permitting process.  Therefore,
 any alternative which includes on-site treatment (i.e., all
 alternatives except No Action) would be designed and implemented
 so as to comply with the substantive requirements of applicable
 permitting processes.

 LONG-TERM EFFECTIVENESS AND PERMANENCE

 Long-term effectiveness and permanence addresses the long-term
 protection and reliability of  an  alternative.   This is a relative
 term and is therefore expressed in the degree of long-term
 effectiveness  and permanence associated with an alternative in
 comparison to  other alternatives  being evaluated.

   Alternative  1   The No Action Alternative offers no long-term
   protection to  human health or the  environment.   The potential
   for direct contact with  contaminated materials  still exists.
   Furthermore, erosion from the waste-fill area would continue  to
   contaminate  downgradient (south  of  the waste-fill  area)  soils.
   This  alternative  will require long-term monitoring indefinitely.
   This  alternative  does not  offer  any  degree of permanence.

   Alternative  3   The Fixation  Alternative would be  somewhat effec-
   tive  in  the  long  term in that contamination  in  excess  of acceptable
   health-based levels  would  be bound up in the cement and  thus
   exposure  pathways  (e.g.,  ingestion,  inhalation) would  be eliminated
-^•However,  the ability  of  this alternative^ tp_ effectively  prevent
   the migration of mercury" from the fixed material  indefinitely_~is
  jjncertain_._  Therefore, long-term monitoring  would  be necessary"
   and tKe" possibility  exists that other  remedial  actions may also
   be needed.  Although  quality control  problems could be minimized
   by removing the waste and  then processing  it  instead  of  in-situ
   fixation  the waste  remaining  on-site would be above heal_thr.based
   levels.  Therefore, this alternative would not  be  more permanent
  ^TfajT-RTt e rna t i v e s  la",  B  and  9.  The  degree of permanence associated
  "with this alteTnaTlve  iff-gteater than  that which would be  achieved
   by Alternatives 1,  4, and 7  since the  durability of cement is
   greater than the construction material  which  would  be  used to
   implement Alternatives 4 and  7.

-------
                              -  13  -
Alternative 4  The Impervious Cap with Extraction Well Alternative
is of limited effectiveness  in the  long term with respect to the
reliabilty of the remedial action.  There is the potential  for
remedy failure since the clay unit  and underlying clay may  not be
adequate barriers to mercury migration.  This potential appears
to be further substantiated  by the  detection of mercury in  the
groundwater.  Since the waste is left on site untreated, this
alternative would require monitoring and maintenance  indefinitely.
As stated above, this alternative is considered less  permanent
than Alternative 3.

Alternative 7  The Excavation Alternative is of limited effective-
ness in the long term with respect  to its ability to  function
indefinitely.  Although less likely, the potential for remedy
failure exists, as with Alternative 4.  The potential for leakage
through the clays is mitigated relative to Alternative 4 by the
installation of a synthetic  membrane liner under the  contaminated
material and above the clay  stratum.  As with Alternative 4, this
alternative would also require indefinite monitoring  and maintenance,
With respect to the degree of permanence, although this alternative
offers a greater degree of permanence relative to Alternative 4,
it is far less permanent than Alternative 3.

Alternative 7a  Alternative  7 with Off-Site Disposal, calls for
contaminated materials to be excavated down to acceptable health-
based levels.  Since all wastes in  excess of health-based levels
would be transported off site there would be limited  groundwater
monitoring to confirm that the action was satisfactorily completed
and no long-term operation or maintenance.  With respect to the
site this alternative offers a higher degree of permanence  than
does Alternative 3.

Alternative 8  The Thermal Treatment Alternative is effective in
the long term in that it reduces toxicity of contaminated material
on site and decrease the concentration of mercury found on  site
to acceptable health-based levels.  As with the preceding altern-
ative, there would be limited confirmatory groundwater monitoring
and no long term operation or maintenance.  Since the toxicity and
the concentration of mercury in the waste is reduced  to health-
based levels, this alternative offers a higher degree of permanence
than does Alternative 3.  With respect to the site, the degree of
permanence associated with this alternative is equivalent to
Alternative 7a.   However, in a broader perspective this alternative
is more permanent than Alternative  7a because the waste is  treated
instead of being relocated.

Implementability addresses how easy  or  difficult,  feasible  or
infeasible it would  be to carry  out  a given alternative.  This

   Alternatives  which  involve  the  off-site  disposal  of  contaminated
   perched  water at a  POTW may pose  implementation problems  with
   respect  to  the availability of  a  POTW which  complies with EPA's
   guidance Memorandum entitled "Discharge  of Wastewater from CERCLA
   Sites  into  POTWS",  dated April  15,  1986.  In addition,  permission
   from the-POTW to accept the waste may be necessary.

   Alternatives  8 and  9 are considered  to be implementable.   Both
   the data collected  by  the U.S.  Bureau of Mines in their screening
   of potential  treatment  alternatives  and  available information on
   similar  industrial  processes suggest that these alternatives are
   viable options.   However, further bench  and  pilot scale studies
   would  be necessary  prior to design  and construction  to  further
   evaluate the  effectiveness  of these  alternatives  and to optimize
   the operating and design parameters  of the treatment process.


COST

The cost evaluation of each alternative is based on the capital
cost (cost  to construct),  long term monitoring, operation and
maintenance cost (O&M) and present  worth costs.

Present worth analysis was used so  that the cost of  each  alternative
could be compared  on  the  same  basis.   The  present worth value
represents the  amount of money, if  invested in the  base year and
then expended as needed, would be sufficient to cover  all costs
of the remedial  action over its planned  life.

The capital, O&M and  present worth  value for each alternative is
provided in Table  2.

COMMUNITY ACCEPTANCE

This evaluation  criterion  addresses the degree to which members of
the local community might  support the  remedial alternatives being
evaluated;  and  is  addressed in the  responsiveness summary.

COMMONWEALTH ACCEPTANCE

This criterion  addresses the concern and degree of  support  that the
commonwealth government has expressed  regarding the  remedial altern-
atives being evaluated.  Puerto Rico's  Environmental Quality Board

 Selected Remedy

 The selected remedial action is Alternative 9: Hyrometallurgical
 Treatment.

 This general type of treatment would be used for the contaminated
 near-surface soil, perched water and waste-fill materials (approxi-
 mately 1500 cubic yards, 1/2 million gallons and 4000 cubic yards,
 respectively).  This alternative involves putting the mercury into
 solution by using a leaching agent such as cyanide,  hypochlorite or
 nitric acid.  The mercury would then be recovered from the aqueous
 solution by using various metallurgical techniques such as filtration
 and cementation/precipitation.   The waste would be mixed with the
 leaching agent until the desired level  of mercury is extracted from
 the waste and put into solution.  The process stream from the
 leaching stage would then be filtered.   The residue  from filtering
 would be disposed of in the former waste-fill area and
 capped with two feet of clean soil.   The process would be designed
 to achieve treatment of mercury from the waste to below health-
 based levels (See ARAR discussion).   Since it is anticipated
 that the treatment process could attain treatment of mercury to  below
 acceptable levels, the actual performance standard for the treatment
 process would be determined by  the maximum removal efficiency
 associated with the  technology  with due consideration to the corres-
 ponding incremental  cost involved in achieving further removal.
 The mercury-laden liquid from the filtering stage would then be
 subjected  to cementation or precipitation.  This process is achieved
 by  passing the liquid  through a material such as stainless steel,
 zinc,  copper or aluminum.

 During  cementation the mercury  is exchanged with the metal and
 precipitated out.  The liquid would  then be recycled back through
 the process.   It  is  anticipated that only one batch  of leaching
 agent  would  be needed.   Upon completion of the process, the remaining
 liquid  would be treated on-site prior to discharge to a POTW.
 Further treatability studies will be conducted during design to
 optimize the treatment process.   The process would be designed to
 meet or exceed levels  protective of  public health.   The estimated
 cost  associated with Alternative 9 is $1,912,870.

 As  discussed  above,  the location and number of existing monitoring
 wells are  inadequate to fully characterize the extent of groundwater
 contamination  at  the site.   Therefore,  further investigation of  the
 groundwater  will  be  conducted during design of the remedial action.
This work  will  include  installation  of  additional  groundwater
monitoring wells  and groundwater sampling.   Additional  remedial
 action  may be  necessary pending  the  results of this  investigation.
 If  further groundwater investigation determines that there are no
 current or future  risks  posed by groundwater contamination,  then
 limited groundwater monitoring would be conducted  to provide further
 verification  (i.e.,  a  minimum of  three  years).   In addition,  air

-------
                                - 19  -
 modelling  was used  in  the endangerment  assessment  to predict the
 concentration of mercury vapors  which could  be emitted given the
 concentration of mercury detected in the  soils and waste-fill
 materials.  The modelling showed that the concentration of mercury
 in  soils and in the waste-fill area may cause the  NESHAP to be
 exceeded.  The NESHAP  for mercury is 1  ug/m3.  Therefore, confirm-
 itory air  sampling will be conducted during  the design to verify
 the whether the NESHAP is being  exceeded.  During  design, confirmitory
 soil samples will also be collected from  residential yards which
 are downgradient in terms of surface water runoff  from the site.

 Statutory Determinations

 Section 121 of CERCLA mandates that EPA select a remedial action that
 is protective of human health and the environment, cost-effective,
 and utilizes permanent solutions and alternative treatment technologies
 or resource recovery technologies to the maximum extent practicable.
 Remedial actions in which treatment which permanently and significantly
 reduce the volume, toxicity or mobility of a hazardous substance is
 a principal element are to be preferred over remedial actions not
 involving such treatment.

 Based upon the analyses presented herein the following conclusions
are reached:

   0 Overall  Protection of Public Health and the Environment

     Alternative 9 provides protection through treatment of waste
     above health-based levels for mercury

   0 Compliance  with ARARs

     Alternative 9 would be designed to meet or exceed ARARs.   As
     stated above,  this alternative  would  reduce  the  concentration
     of  mercury  down to or below health-based levels  in the absence
     of  chemical  specific ARARs for  soils  and debris.   The  residuals
     will  be  deposited  on site and  covered with clean soil  consistent
     with  a RCRA clean  closure.

   0 Utilization  of  Permanent Solutions and Alternative Treatment
      Technologies  to  the Maximum Extent Practicable
                                 »

     Alternative  9  is  considered  to  be  a permanent remedial action
     since  the concentration  of mercury remaining  on  site would be
     below  health-based levels.  For this  reason Alternative 9
     has a  greater degree  of  permanence  relative  to Alternatives 1,

-------
                                - 20 -


      4 and 7 where wastes are left on-site, untreated, in concentrations
      exceeding health-based levels.  Although Alternative. 3 uses
      treatment to reduce the mobility of the waste (and possibly
      the toxicity) the concentration of mercury in the waste
      remaining on-site would be above health-based levels.   Therefore,
      Alternative 9 is preferred over Alternative 3 because  it does
      not require indefinite management and monitoring of the site.

      The degree of permanence associated with Alternative 9 is
      equivalent to Alternatives 8 and 7a with respect to the site.
      The degree of permanence associated with Alternative 7a is
      limited in that it only addresses permanence in terms  of on-site
      conditions.   Alternatives 8 and 9 would be permanent with
      respect to off-site as well as on-site conditions.

      Alternative  9 uses alternative treatment technologies  to the
      maximum extent practicable since it includes treatment of
      all waste with mercury concentrations in excess of  health-
      based levels.   The other treatment alternatives (i.e.,
      Alternatives  3 and 8)  also require the treatment of  all waste
      with mercury  concentrations in excess of health-based  levels.
      However,  Alternative  3  does not provide for recovery of mercury
      from the waste.   Thus,  Alternatives 8 and 9 have the added
      benefit  of using  alternative treatment technologies  to the
      maximum extent practicable while recovering mercury  from the
      waste thereby  resulting in the conversion of a  waste into a
      usable material.

    0  Preference for Treatment as a  Principal Element

      Alternative 9  satisfies the  statutory preference for treat-
      ment as  a principal element of a remedial action since it
      provides  for treatment  of organic  mercury to inorganic mercury
      which significantly reduces the toxicity of the wastes.

    0  Cost-Effectiveness

      Although  Alternative 9  is not  the  least costly  treatment
      option  it  is cost-effective.   The  costs are reasonable in
      light of  the relatively small  incremental (approximately
      1 million  dollars) cost associated with attaining a  permanent
      remedial  action, with limited  monitoring,  no land use  restrictions
      and  which  utlizes treatment  as  a principal  element.

In  summary, Alternative 9 is the  selected  alternative, it is  protec-
tive  of public  health, is cost-effective,  and  utilizes treatment
as  a  principal  element.  Alternative  9  would provide  protection of
public health by using treatment  to  reduce  the  concentration  of
mercury on site to  below health-based levels (See ARAR discussion).

     The treatment process employed would reduce the toxicity of the
     waste by converting organic mercury into a less toxic inorganic
     form and would reduce the volume of contaminated materials which
     are above health-based levels.  Since the residua.1 mercury concen-
     tration in materials left on site would be below "health-based
     levels, this alternative is considered a permanent remedial action.
     Studies conducted by the U.S. Bureau of Mines and available infor-
     mation on related industrial processes suggest that this alternative
     could be implemented.  Further bench and pilot scale studies would
     be required to optimize the treatment process and minimize any
     potential short-term impacts.  Alternative 9 would be designed to
     meet or exceed ARARs.  The estimated cost for implementing Alternative
     9 is $1/912,870, which is reasonable in light of the degree of pro-
     tection, treatment and permanence afforded by this alternative.

     Currently,  Alternative 9 appears to provide the best balance of
     trade-offs among the alternatives examined in detial with respect
     to the nine evaluation criteria.  In addition to satisfying the
     statutory preference for remedies which utilize treatment as a
     principal element and for permanent remedies.  EPA believes that
     Alternative 9 is implementable based on current information.
     However, since this alternative has not been fully demonstrated and
     further treatability studies are necessary, EPA believes that it is
     prudent to  conduct additional treatability studies on other treatment
     options concurrently with those to be performed for Alternative 9.
     This approach would minimize any delay in remediating the site, in
     the event that hydrometallurgical treatment is not implementable.

     A.    OVERVIEW

          On September  i,  1988,  the  U.S.  Environmental  Protection
     Agency  (EPA)  Region  II  began  a  public  comment  period on  the
     proposed remedial action plan (PRAP) and  supporting information
     for the G.E. Wiring  Devices  Superfund site  in Juana Diaz, Puerto
     Rico.    Prior to the  public  comment period, EPA had proposed an
     alternative  for  cleanup  of  the  G.E. Wiring  Devices site.    The
     preferred  alternative outlined  in the PRAP is hydrometallugical
     treatment, which involves mixing on-site waste containing mercury
     with   a leaching agent  to  create  a  solution  containing  the
     mercury.   The solution is  filtered, then the  mercury is removed
     by  precipitation  or  cementation.   The  mercury  could  then  be
     recovered.

         This responsiveness summary  addresses  questions and comments
     about  the  G.E.  Wiring Devices  site  received during the  public
     comment period.  These sections follow:

                   (Spanish Version).

    B.   COMMUNITY INVOLVEMENT IN THE SELECTION PROCESS

         On  the   evening  of September 15,  1988,  EPA  held  a public
    meeting  in  the  Municipal Assembly Office  in  Juana  Diaz, Puerto
    Rico,  to present the  PRAP  and supporting documents  for  the G.E.
    Wiring  Devices site.   Because Spanish is the  primary language of
    the  majority of the  local  residents, the  meeting  was  held  in
    Spanish  and  English to foster public involvement.   A member of
    the EPA Caribbean Field Office staff translated  questions to  and
    responses  for non-Spanish  speaking  EPA representatives  at  the
    meeting.   In addition  to  being  available at  the  information
    repositories, copies  of the  PRAP and mercury  contamination fact
    sheets,  in English and Spanish, were  distributed  at the meeting.
    The  two^-and-one-half hour  public  meeting  was  attended   by
    approximately 25 persons.

         Earlier  in  the day, EPA  held  a briefing for  Commonwealth  and
    local  officials  that was attended by approximately 15 people.
    Questions raised during both  the  public meeting and the  briefing,
    as well  as written  questions and comments received  by EPA during

 C.   SUMMARY  OP  COMMENTS  RECEIVED  DURING  THE  PUBLIC  COMMENT
      PERIOD

      Comments  received  during the  G.E.  Wiring  Devices public
 comment  period  on   the  PRAP  and  supporting  documents  are
 ?ummaraL2ed below-   Tne comment period was held from September 1
 1988,  to September 26,  1988.   The  comments  are  categorized by
 topic   and  similar   questions  have   been  consolidated  and
 summarized.

 Site Remediation Schedule

      1.   A  local  official  asked about the  schedule  for  site
           remediation.

           PA.  Response;    EPA  expects  to  sign  the  Record  of
           Decision  (ROD)  for the  G.E. Wiring Devices site at the
           end of  September.    After the ROD  is  signed,  six  to
           twelve  months  of   treatability  studies   will  be
           performed;  therefore,  it will  be  about  one year before
           the remedial  action is undertaken.

      2.    Several  people  asked how  long  remedial  action would
           take  once the treatability studies were completed.

           EPA Response:    The  time  frame  for remediation  will
           depend  greatly  on the  volume of  waste  that  can  be
           treated  at any particular time.    It  is  difficult  to
           make  an  accurate prediction as to  the  actual length of
           time  for remediation  until  the  treatability studies are
           completed.

Rationale  for Selection of the Preferred Alternative

      1.    A local official  asked if Alternative 9  was proposed  by
           EPA  because   it  was   one  of   the  least   expensive
           alternatives.

           EPA Response;   Although  Alternative 9 is  less expensive
           than Alternatives 7a  and 8, it is more  expensive  than
           all  of  the  other  alternatives.    EPA  believes  that
          Alternative  9  is  the most effective  method  of  site
          remediation  and  did   not  select  it  purely on  a
          lower-cost basis.

Past Sampling

     1.    It  was  asked if the  residential  yards  near the  site
          were sampled.


                               - 2  -

-------
           EPA Response?   Yes,  but the data were  not validated.
           Further sampling will be  performed  during the remedial
           design phase  to  attempt  to confirm these data.

      2.    One citizen asked what steps EPA took to talk to people
           who live near  the site.   She stressed that  she lived
           near the site and her yard was not sampled.

           EPA Response;  Not all of the houses near the site were
           sampled.   The  decision  to sample or not  was  based on
           the probability of finding contamination.   Houses that
           had  the  highest  probability  of  contamination  were
           sampled  —that   is  those  houses  which  are  in  the
           direction of  surface  ground-water runoff,   with respect
           to  keeping local residents informed  as to the status of
           the site, EPA has held  several public meetings  in the
           area.    A public  notice  in the  newspaper was used to
           announce  the  recent  meeting.     In  addition,   local
           officials are kept informed of the current site status,
           and they in turn,  inform their constituents.

Health Effects

      1.    Several  people  asked  if EPA had  considered the effects
           of  the site on health of local residents.

           EPA Response;   An Endangerment Assessment was conducted
           by  EPA which indicated  potential emissions of mercury
           vapor   above  health-based  levels.    With  respect  to
           worker   exposure,  no   exposure   levels  above   the
           Occupational  Safety  and  Health  Administration  (OHSA)
           standard  were   found  or  predicted  at  this  site.
           Although  General  Electric  (G.E.)  performed some testing
           during the  Remedial   Investigation,  EPA  will  perform
           more air  sampling  during remedial design.

      2.    Several  people  wanted  to know  if  EPA  will perform  a
           health assessment  on  the  site  community  and  plant
           workers.

           EPA  Response;   The Federal agency responsible  for this
           type  of  investigation  is  the   Agency  for   Toxic
           Substances  and  Disease  Registry  (ATSDR).    There  is  a
           provision  in  the  law  for  individual  persons  or  local
           physicians  to  petition  ATSDR   to   perform  a  health
           assessment  if the probable  source  of  exposure  is  a
           release.    Further information   on  this  procedure  is
           available from the EPA Regional Office or the Caribbean
           Field  Office.

Volatile Organic/Waste Water Contamination

            the plant were inconclusive  regarding the existence of
            the sump.   EPA followed up  with more  monitoring well

 Public Notice
      1.    A concern  was raised  that adequate  public notice  was
           not given for the meeting.
               Response;   EPA used several methods  to inform  the
           public of the  meeting.   EPA published  a public  notice
           iS a»r£tWSpa?er announci«9 the  meeting  and  summarizing

           due  to  construction  at  the  Mayor's  Office, it   was
           necessary  to   change  the  meeting  location  to   the
           temporary  Municipal  Assembly  meeting  room   down   the
           street.   A member of the  Mayor's  staff was posted at

One citizen  asked for information concerning the years
that  G.E.  disposed  of  contaminated  materials  at  the

r-
   D.  The following comments from General  Electric were i-ece*ved  in
   writing during the  public comment  period.

   Comment 1;

   The data relied upon does not  fully  characterize the site.
   Specifically,  there is  a  lack  of data with  respect  to air releases,
   groundwater conditions  and the nature of mercury in the waste.

   Response;

   Data collected by G.E.  during  the  remedial  investigation was
   reviewed by EPA for conformance with EPA quality assurance/quality
   control  protocols.   The data was determined to  be unusable because
   it  did  not  meet EPA specifications.  In addition, the groundwater
   monitoring  wells at  the site are insufficient and improperly located.

   In  August 1988,  EPA collected  additional samples with the objective
   of  obtaining data which would  be in  accordance  with  EPA guidelines
   and  representative  of the  nature and degree of  contamination in
   the  waste-fill  materials,, perched  water and contaminated near-surface
   soils.  Groundwater  samples were also collected  and  analyzed from
   existing wells  to provide  some  valid data on groundwater conditions
   (Because it was recognized the  number and placement  of monitoring
   wells is limited, EPA was  aware that this data  could  not be used to
   conclusively demonstrate  that  no groundwater contamination exists
  at the site.  However,  if  positive results were obtained, they
  could provide a basis for  determining whether leakage had occurred
   through the waste-fill area through the underlying strata and
   into the aquifer.)

  While EPA recognizes that  the database is somewhat limited with
  respect to  air and groundwater sampling, we believe that the data
  is sufficient to characterize the nature and extent of contamination
  in the waste-fill area and with reasonable interpretation the con-
  taminated near-surface soils.  The  waste-fill area and contaminated
  soils may pose unacceptable risks to public health if unremediated.
  Rather than delay the remediation of these areas pending additional
  study of the groundwater,  EPA believes  it  is more prudent to
  address the risks posed  by these areas  since selection and imple-
  mentation of a remedial  alternative for  these  areas is not contingent
  upon the results of  the  groundwater investigation.

  In EPA's endangerment assessment an air  model  was used to calculate
  the  concentration of mercury in soils and  the  waste-fill area which
  could result in exceeding  levels protecive  of  public health.   The
  model predicted that a concentration of  16.4 ppm would result in
  exceeding health based criteion. The model  provides a reasonable
  indication  of actual field conditions.   However, confirmatory air
  sampling  will  be conducted during design to  verify the results  of
  the  model since the  confirmatory air monitoring  will affectd  the

  ?™~ fesPfct to limited groundwater data,  the need for further
  investigation is substantiated by, among other  things, the
  s!e?S S10n ?  mercury in one sample of the groundwater above  health-
  based levels (i.e.,  the Maximum Contaminant Levels promulgated
  dS?nanLt(? the ?afe Drinkin9 Wat®r Act).   This work  will be conducted
  during design.   As stated  above, the remediation of the waste-fill
  area and  contaminated soils is not contingent upon the results of
  tnis investigation.

  In  regard  to the data defining the nature  of  mercury  in the
  wastes, EPA found that  the  mercury in the  perched  water, near-
  ?™aCeJ!01r,Soand> 9roundwater is predominantly  in  an  inorganic
  form.  The  U.S.  Bureau  of Mines  analyzed the  plastic portion  of
 Thl  ~f,t;?,.ln.tS? WaS^fi11  3rea for Or9anic  forms of  mercury
 The  results  indicated low levels  of  organic mercury in  the plastic.

 Comment 2:

 EPA used air modelling  results from  its endangerment assessment
 for determining cleanup levels.  Adequate air monitoring has not
 been conducted and therefore  the cleanup level has not been defined.
 Response
 EPA has used the air modelling results in the endangerment assess-
 ment as a tool for determining preliminary cleanup levels for the
 site,  confirmatory air modelling will be conducted during design
 to refine this value.  Since EPA has demonstrated in its endanger-
 £!!?^aSfKSS:neut.that the site may P°se unacceptable risks to public
 health through ingestion pathways, confirmatory air sampling
 would not negate the need for site remediation.  The air sampling,
 however,  could affect the volume  of contaminated material which is
 remediated.

 Comment  3:

clarification.

Response;
EPA encourages public  involvement, comment  and participation  in
the remdy selection process.  Accordingly,  it is standard Agency
practice to publish draft RI/FS reports and endangerment assess-
ments so that EPA may  solicit public input  prior to the finali-
                              - 6 -

-------
zaticn of these documents.  For this particular siter these
documents have undergone continued agency review concurrent with
the public comment period.  Although the endangerment assessment
has been modified somewhat as a result of this review it continues
to establish a need for site remediation.  Specifically, the
modifications have resulted in a reduction of the acceptable
mercury exposure level due to ingestion of contaminated materials
from 38 ppm to 21 ppm.  Moreover, for reasons stated above, such
changes do not affect the evaluation or selection of remedial
alternatives.


Comment 4:

"The A[ddendum] FS applied unfounded or improper assumptions
regarding the potential (emphasis added) risk to human health and
environment..."  Specifically, "the possibility of leakage through
the clay layer to the groundwater is the basis of rejecting other
alternatives [in particular Alternative 4 which is basically on-
site containment].  Without the data confirming such an assumption,
that conclusion is unsupported."

Response;

EPA's determination that the potential for current and future
groundwater contamination exists is based in part on the work
conducted by G.E. and statements contained in their RI report.
In particular, the RI indicates that the permeability of the clay
layer is in the range of 10~4 - 10~5 cm/sec.  EPA considers these
values as demonstrating moderate permeability.  (Model RCRA
specification would require a 10"' cm/sec permeability for an
"impervious" liner).  In addition, the RI reports that roots were
observed in this unit, which would further facilitate the migration
of mercury through the clay by providing channels for the contam-
ination to flow through, and thus increase the permeability of
the soils.  Furthermore, the RI finds low resistivity readings in
portions of the waste-fill area.  The report then explains that
these readings may be indicative of a zone of high moisture
content underlying the waste-fill area.  The report states that
this moisture could be the result of slow downward migration of
perched water through the silty clay stratum.

Notwithstanding the information provided by G.E., the inability
of the clays underlying the waste-fill area to act as an adequate
barrier to contaminant movement to the groundwater appears to be
evidenced by the detection of mercury in the groundwater.

 Response;

 One of  the deficiencies of the GE draft FS was that it did  not
 op;i^COnr°rm  Wiirh  ^he  criteria  set  forth  in Section 121  of
 CERCLA.  in particular,  the alternatives were not evaluated with
 respect to;  long-term  effectiveness  or permanence;  reduction of
 toxicity,  mobility  or volume; and short-term effectiveness.   In
 addition,  due  consideration was  not given  to alternatives which
 utilize permanent solutions and  alternative treatment technoloqies
 or resource recovery technologies to  the maximum extent practicable
 as directed by CERCLA.   Furthermore,  CERCLA mandates that remedial
 actions in which treatment  that  permanently and  significantly
 reduces the volume, toxicity or  mobility of a hazardous substance
 is a principal  element are  to be  preferred  over  remedial actions
not involving such  treatment.  The GE draft FS did  not address
evaluation of the alternatives with respect  to this  preference.

          EPA believes that Congress* intent is clear with regard to this
          issue.  We disagree with the assertion that this criterion was
          given undue weight to the exclusion of all other criteria.
          It is self evident that EPA in the addendum FS fully considered
          all of the criteria while giving the prcper preference (as mandated
          by law) to remedial actions which involve treatment and which
          permanently and significantly reduce the toxicity, mobility or
          volume of a hazardous substance.

          As stated above, the criterion which involves reduction of
          toxicity, mobility or volume was applied to the pertinent alter-
          natives (See language and discussion in FS).

          Comment 7:

          The process proposed by EPA has not been demonstrated as being
          viable.  Although some processes identified may be practiced in
          the extraction industries,  no location has been identified where
          wastes similar to that at the Site has been successfully processed
          on a scale similar to that required at the Site.

          Response:

          EPA believes that hydrometallurgical treatment is a viable
          process.   It appears to be  implementable based upon laboratory
          studies conducted, as well  as, other work performed by the U.S.
          Bureau of Mines and published literature.  As stated above,
          aspects of the process are  currently and routinely practiced in
          the extraction industries.   However, EPA recognizes that further
          treatability studies are necessary and has committed to conduct
          such studies during design.   With respect to the concern that no
          location  has been identified where wastes similar to that at the
          Site has  been successfully  processed on a scale similar to that
          required  at the Site,  Section 121 of CERCLA clearly allows EPA to
          select remedial actions with alternative treatment technologies
          which meet the objectives of the evaluation criteria, whether or
          not such  action has been achieved in practice at any other facility
          or site that has similar characteristics.

          Comment  8:                                              .

          The degree of reduction of  mercury is highly speculative.   All
          of the assumptions are based on processing cinnebar ores,
          generally containing higher concentrations of mercury.  The
          wastes found at the site may not pose the same processing issues
          as ores.
                                        - 9 -

-------
 Response;

 Again, Section 121 of CERCLA allows EPA to select remedial
 actions with alternative treatment technologies which meet the
 objectives of the evaluation criteria, whether or not such
 action has been achieved in practice at any other facility or
 site that has similar characteristics.  EPA is aware that the
 wastes found at the site may not pose the same processing issues
 as ores which is among the reasons for performing further
 treatability studies during design.  In addition, the percent
 reduction achieved in current industrial extraction processes
 should not be used as a basis for determining the upper  limits
 of the selected treatment alternative.  These are commercial
 processes where the extraction goals are primarily based on
 cost and benefits of further treatment verses value of recoverd
 materials.  EPA's treatment goals are based on attaining conformance
 with the criteria specified in CERLCA.  EPA's objective  is to select
 a  remedial action which provides the best balance in terms of
 tradeoffs with respect to such criteria.  While cost-effectiveness
 is a criterion which is considered, it does not necessarily drive
 EPA's decision making process.

 Comment  9;

 The  short-term effectiveness has not been addressed with respect
 to hydrometallurgical treatment.

 Response;

 The  short-term effectiveness was assessed and short-term impacts
 were  noted  in  the  addendum  FS for each alternative  including
 hydrometallurgical  treatment.   This criterion was applied
 consistently  to each  alternative.   That  is,  potential  short-term
 impacts during implementation were identified for each alternative.
 A  conservative approach  was  taken in  identifying  such  potential
 impacts.   For  example,  the  formation  of  picric acid  is possible
 when  concentrated nitric  acid reacts  with phenols  in the presence
 of sulfates.   Although  there is  nothing  in  the waste  that  suggest
 that  there are high  levels  of sulfates or sulfite,  since the
 plastic materials contain phenolic compounds,  the  potential formation
 of picric acid was  flagged.   Moreover, in laboratory tests  the
 waste was analyzed  using  concentrated  nitric  acid,  and picric  acid
 was not formed.  Potential short-term  impacts  were  also  addressed
 in the same manner  for each  alternative.  That is,  EPA believes
 that  the issues raised can be addressed  in  the  site health  and
 safety plan for construction.  EPA also  believes  that  any  short-term
 impacts associated with hydrometallurgical  treatment can be
addressed through data collected  during  the  treatability studies.
                              -10 -

Comment 10:

"With all the uncertainties associated with this process
[hydrometallurgical treatment] any cost estimates are at best an
educated guess."  "Cost could easily balloon to half again or
more."

Response:

EPA's goal when developing cost estimates for the FS is to achieve
a level of accuracy between + 50% to - 30%.  EPA realizes that this
goal may not be pratical for remedial actions which entail excavation
and treatment of wastes.  EPA believes that the assumptions made
in the cost estimates are reasonable.  However, the cost estimates
will be further refined upon completion of the treatability
studies and subsequent design.

Comment 11:

"The Fixation Alternative was rejected without adequate evaluation.
Although it would meet the necessary requirements for human health
and environmental protection, there appears to be some concern
over its permanence.  Some of this is traced back to the erroneous
assumptions that this would be performed in situ."  The
resultant material from fixation "has a high degree of permanence
and no specific evidence was presented in the A[ddendum] FS to
the contrary."

Response;                                                .

The evaluation of the degree of long-term effectiveness or permanence
associated with the Fixation Alternative was not solely dependent
upon the difficulties encounted with respect to in-situ treatment
processes.  Quality control concerns, such as achieving proper
mixing of the waste, may be addressed by removing the waste for
processing and then returning it to the waste-fill area.  And,
these activities may also increase the degree of permanence
associated with this alternative.  However, the degree of permanence
is still uncertain.  Although acid leaching tests have been
performed on a fixed sample from the waste-fill area, and these
tests give a good indication of the initial short-term effectiveness
of fixation.  However, the tests offer no information with respect
to the long-term ability for this alternative to be effective
under a variety of in-situ conditions.  Processing the waste
outside of the waste-fill area would still not make the Fixation
alternative a more permanent solution than the chosen alternative,
since wastes would remain on-site above health-based levels.

  hHi*  ™  ?  H  ?  Alternatives  5,  5a,  6  and  6a were eliminated
  based  on  technical  fesibility  since the  waste is not amenable
  to  physical  separation;  this appears  to  directly contradict Law
  Environmental's report of November 1987  which references a
  Granulametnc  Study Report of  November  1986 which indicates
  that some  physical  separation  can be  achieved by screenino.
  EPA provides no supporting documentation for their rejection of
  Alternatives 5,  5a, 6 and 6a."
 Response:
 Because no mass balance was performed, the work conducted bv
 Law Environmental with respect to the above-referenced altern-
 atives is inconclusive.  The data presented in the Bureau of
 Mines report demonstrates that some physical separation of the
 mercury from the waste materials could be achieved.  However
 these physical separation methods do not achieve sufficient
 S*?*C*i?n-a2d are.thefef°re inefficient and impractical.  The
 data and information is presented in the Bureau of Mines report
 which is an attachment to EPA's addendum FS.


 Comment 13:

 "EPA does  not indicate in their summary that extensive safety
 features would need  to be designed into a temporary facility
 because of the use of hazardous leaching materials, nor do they
 state  that the leachates  would require treatment  and disposal
 after  removal of  the mercury."

 Response:

 The  addendum  FS does provide  for  neutralization of  the leaching
 agent  prior to disposal at a  POTW.   As stated  in  the addendum
 FS,  safety concerns  will  be addressed  in the design and  health
 and  safety plan.

 Comment 14;

 "There  is  no  supporting data  to demonstrate  that  the hazardous
 leaching materials (cyanide,  nitric  acid, or hypochlorite) can
 themselves be removed sufficiently that  the  soil will  meet
 relevant disposal criteria".

Response:

See response to Comment 7.  The remedial action will be designed
to meet relevant disposal criteria.

Comment  15:

"Treatment of perched water  is based on an estimated 500,000
gallons  already in the area; no allowance appears to be made
for recharge due to nine months percipitation over a 1.16 acre
area, which would amount to an additional 1,140,000 USgal over
the nine month period, assuming 48 inches of percipitation per
year."

Response:

EPA used the same value (i.e., 1/2 million gallons) for the
volume of perched water to be treated when assessing each and
every alternative.  The amount of time estimated for implement-
ation of each alternative is sufficiently similar (between 18 to
24 months) and therefore, the incremental amount of perched
water generated should be roughly equivalent.  Consequently,
each alternative would be affected in a similar manner if
rainfall increases the volume of perched water to be treated.


Comment 16:

"EPA states that the mercury could be recovered from plastic by
low temperature retorting between 375°C and 850°C, implying
that this is an established process.  However, the U.S. Bureau
of Mines letter of August 22, 1988, states only that additional
tests are being run to determine if this could be achieved."

Response:

The first statement in the comment is part of a sentence The
sentence in the addendum FS is explaining the range of possible
temperatures which should be explored to determine the optimal
operating temperature for a thermal treatment process.  EPA
does not state or imply that low temperature retorting for this
waste is an established process; this is an inference drawn by
the commentor by taking a statement contained in the addendum
FS out of context.

Comment 17:

"EPA has proposed using cyanide, hypochlorite or nitric acid
to leach mercury from the waste materials and soils based on
the August 22, 1988 letter from the U.S. Bureau of Mines (USBM).
However, the USBM eliminated nitric acid as a leaching medium
because of the hazard of forming potentially explosive nitrated
organic compounds from the phenolic plastics present in the waste*
"Although USBM rejected cyanide as a leaching medium, cyanide
leaching of gold and silver ores is a commercial process '

        These process streams, as well as their ultimate disposal were
        identified in the addendum FS.  Hydrometallurgical treatment
        consists of leaching mercury from the waste with a leaching
        agent.  This generates a liquid-sludge stream.  This stream is
        then filtered.  The concentration of mercury in the residual
        material (sludge) from the filtering stage is below health-based
        levels.  The residuals are then rinsed to ensure that all of
        the leaching material is removed.  The rinsate is treated
        on-site, prior to discharge to a POTW.  Treatability studies
        will determine the design parameters which will ensure that the
        residuals will be below health-based levels and not contain
        hazardous byproducts from the leaching stage.  The residuals
        will then be disposed of on site.  The liquid stream separated
        from the sludge during the filtration stage will then undergo
        precipitation/ cementation to remove the mercury.  This process
        consists of passing the liquid through a material such as
        stainless steel, copper, aluminum or zinc.  The mercury is then
        removed from the solution, and sent to a reclaimer or proper
        disposal in accordance with its characteristics.  The liquid is
        then recycled back to the leaching reactor.  When the processing
        of all waste is completed the leaching agent is neutralized and
        sent to a POTW for disposal.
