  SITE NAME AND LOCATION.
  South Cavalcade Street Site
  2001 Collingsworth Street
  Houston, TX

  STATEMENT OF BASIS AND PURPOSE. This decision document presents an amendment to
  the selected remedial action for the South Cavalcade Street She which was chosen in accordance with
  the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA),
  as a nended by the Superfund Amendments and Reauthorization Act of 1986 (SARA) (42 U.S. Code,
  Section 9601, et seq.), and, to the extent practicable, the National Contingency Plan (NCP) (40 CFR
  Part 300).  This decision is based on the Administrative Record for this site. The State of Texas
  concurs with this amended remedy.
  ASSESSMENT OF THE SITE. Actual or threatened releases of hazardous substances from this
  site, if not addressed  by implementing the response action selected in this Amended Record of
  Decision,  present  an  imminent  and substantial  endangerment to public health, welfare or the
  environment.
  DESCRIPTION OF THE REMEDY. This amendment fundamentally changes the Record of
  Decision (ROD) executed by the Regional Administrator on September 26, 1988. This amended
  remedy will seal and contain soils contaminated with greater than 700 ppm carcinogenic polyaromatic
  hydrocarbons (cPAH) beneath a six inch thick reinforced concrete cap.
  STATUTORY DETERMINATION. The selected remedy is  protective of human health and the
  environment, complies with Federal and State requirements that are legally applicable or relevant and
  appropriate to the remedial action, and is cost-effective. This remedy utilizes a permanent solution
  and alternative treatment technologies to the maximum extent practicable. The questionable success
  of soil washing, the previously selected remedy, and the comparable risk off-site preclude selecting
  a remedy which treats the contaminants of concern.  Since contamination at the site prese *s only
  low level threats, and treatment of the contaminated soil at the she was not found to be practicable,
  this remedy does not satisfy the statutory preference for remedies that  employ treatment as a principal
  element. However, as described in the folio ving Amended Record of Decision a reinforced concrete
  cap will sever the exposure pathway and thus protect human health and the environment.
  Because this remedy will result in hazardous substances remaining onsrte above health-based levels,
  a review will be conducted within five years after commencement of remedial action to ensure that
  the remedy continues to provide adequate protection of public health, welfare, and the environment.
                                                                   6-27-

-------
 I.      INTRODUCTION. In 1988. EPA issued a Record o: Decision iROD) for the South Ovalcade Street Superfund Site
 which selected  soil flushing and soil washing as the remedies to remediate wood treating wastes in the soil.  However, us
 discussed below, following a soil washing pilot study, it became apparent to EPA that the selected remedy would not achieve
 the remedial action  'oals established in the ROD. Consequently. EPA decided to propose u change :o the remedy at the site
 dirough this ROD amendment to cover the contamination with a concrete cap.
        i.      Site Name and Location. The South Cavalcade Street site was once '.he site of a former coal tar distillation and
 creosote wood preserving facility The contaminants of concern in on-site soils are seven carcinogenic compounds' released
 from the creosote wood preservative prior to 1962. when wood treating operations ceased  The site is located in urban northeast
 Houston, Texas about one mile southwest of the intersection of Interstate Loop 610 and U.S. Route 59 < figure I &. 2). The
 boundaries of the 66 acre site are Cavalcade Street to die north. Collingswonh Street to the south, and the Houston Belt and
 Terminal (HB&T) lines to the  east and west. The site is generally flat and is drained by two storm water drainage ditches
 flanking the east and west sides. These ditches discharge into Hunting Bayou, a  Houston Ship Channel tributary.
       The site is presently used by three commercial freight truck companies:  Trucking Properties. Nations Way Transport
 Service, and Palletized Trucking. These companies erected terminal, office and maintenance buildings on the northern and
 southern pans of the site. The centrj pan of the site remains vegetated and vacant.  Surrounding the site are commercial.
 industrial and some residential properties.  The nearest residential area is directly to the west and across the HB&T railroad
 traces; however, (here are no residential properties jdjaccm to a site boundary.  EPA anticipates the site will continue to be used
 as commercial freight truck terminals for the foreseeable future.
       b.      Lead and Support Agencies.  EPA is the lead agency overseeing she remediation under the terms of a Consent
 Decree executed by Beazer East. Inc. ("BET), and entered yy the VS. District Court for the Southern District of Texas on
 March 14.1991 (Civil Action No. H-90-2406).  Under the Consent Decree terms. BEI is responsible for remediating the site
 in accordance with the remedy selected by EPA, as reflected by the ROD executed by EPA on September 16.1988. A copy
 of the ROD is included in the  Administrative Record as explained in the paragraph below.  The. Texas Natural Resource
 Conservation Commission (TNRCQ provides EPA remedial action support on the site.
       c.      Administrative Record.  This ROD  amendment wiD become pan of the Administrative Record  file in
 accordance with the National Contingency Plan  (NCP). 40 CFR }300.825(aK2).   The Administrative Record contains
 documents such as the "Remedial Investigation/Feasibility Study* (RI/FS) and ROD. that form the basis for selecting the
 remedial action.  In  arlrlirion rinnimm^ alTytM-H K> "f fff»T«< in tfrit ^ffnltr^ ttrrrwrt nf rWitinn am inrr»pn"t«-rf into

       d.      Explanation of Difference- In lieu of using the soil washing and soil flushing remedies originally selected in
 Ac ROD, the remedy described in this amendment is to seal areas where surface contamination exceeds the ROD established
 soil cleanup goal - 700 ppm total carcinogenic polyaromabc hydrocarbons  (cPAH): - with a reinforced concrete cover. The
 ROD established 700 ppm as die soil cleanup goal to "._  prevent against an excess lifetime increased cancer risk of S  x 10*
 for likely on-site exposure to soil"1  Site risk is further discussed in this amendment under the title "Summary of Rationale
 lor Changing the Remedy Selected in the ROD."  This amodmenl affects only the soil remedial action whereas on site
fToandwaUr remedial action remains unchanged.
1 The carcinogenic compounds are benzo(a)artthracene. benzo(a)pyrene. benzo(b)fluoramhene. benzo(k)fluoranthene.
chrysene. o%enzo(a.h)antnracene and ideno(1.2.3-cd)pyrene.

         Since capping contamination changes the remedial approach originally established in the ROD. EPA considers this
  a  "fundamental" change and must amend the ROD  in accordance with the  Comprehensive Environmental Response.
  Compensation and Liability Act (CERCLA). Section I  I7(c>. 42 U.S.C. 5 96I7(c). and the 1990 National Contingency Plan
  (NCP) at 40 CFR § 300.435(cX2X»).  However, as explained in the following paragraphs. EPA believes this change will
  continue to protect human health within the acceptable  risk range defined in the N'CP at 40CFR § 300.430

 contain the wastes at the site. EPA considered the May 25, 1995. Land Use in The CERCH Remedy Selection Proces
 (OSWER Directive 9355.7-04). As described in the NCP. 40CFR § 300.430.1 a)< 1 MiiiXA). EPA prefers permanent solution
 to reduce the toxiciry. mobility, or volume of the wastes and the treatment of all principal threats. However, in 1 991 . three yea/-
 after the ROD was signed, EPA published guidance defining "principal threat."10  In accordance with that guidance.  EPA doe:
 sot consider the contamination on site to be a principle threat since the base line risk assessment did not identify any health ri«J
 from any of the soil contaminants on site greater than 1 in 1000 ( 1 x 10 V Therefore, since the waste on site is not considers
 * principal threat the NCP 40 CFR § 300.430.(aXIXi"XB) now allows  EPA to use "... engineering controls, such  a-
 Containment, for waste that poses a relatively long term threat "i: EPA believes a concrete cover will provide reliable protection
        As a result of BEI's proposal. EPA re-evaluated the reasonably anticipated land use and the potential  exposur.
 pathways (see Table 1 ) for the designated land use from the original Record of Decision.  Using the aforementioned land us«.
 directive EPA developed future land use assumptions with information such as population  growth patterns, accessability to tfv
 site, institutional controls in place and site location."  This evaluation lead EPA to conclude that the current land use. freight
 truck terminals, will continue to be the land  use for the foreseeable future and will  remain nothing other than industrial use
 because of population growth patterns, accessability to the site, msuruaonal  controls and its location.  This is a change from
 EPA's original land use assumptions.
        At  the time   that  the  site  was  under
 investigation, inadvertent ingestion, dust inhalation, and
 direct contact by utility or construction workers were
 likely exposure assumptions. However, as a result of an
 Administrative Order on Consent, entered in 1992, each
 landowner has placed a deed notice on file to alert
 future landowners that contamination remains on site.14
  The  order also prevents landowners from drilling
 water wells on site; requires landowners to  preserve,
 protect,  repair  and  maintain  existing  concrete
 foundations and paved areas: and provides notice mat
 residential  use of the site  is  inappropriate.
 Consequently, this  pathway  is no longer realistic
 because  future owners are forewarned and  can take
 measures to protect utility or construcdon workers from
 inadveneir ingestion, dust inhalation and direct contact
 with contaminants on the site.
                                              "
EXPOSURE PATHWAYS
•      Inadvertent ingestion, dust inhalation, and
       direct contact with surficiai soils by utility or
       construction workers;
•      Inadvertent ingestion and direct contact with
       drainage ditch sediments by trespassing
       children; and
•  .    Inadvertent ingestion and direct contact with
       surface soils by future residents if the site
       were ever developed.
•      Inadvertent ingestion and direct contact with
       surface soils by on-site commercial
       occupants
                                                 Table 1 Four Exposure Pathways Assumptions.
        Although inadvertent ingestion  and direct
contact with drainage  itch sediments by trespassing
Children was considerec a potential exposure according
to the remedial investigation studies, this exposure had a maximum noncarcinogenic hazard index of less than 0.01 and a
maximum excess lifetime cancer risk of 1 x 10"*.  The risk estimate for this exposure pathway is within the acceptable range
defined in the NCP. 40 CFR § 300.430
-------
 SOl'TH CAVALCADE SUPERFUND SITE.
 AMENDED HOD NO. 1
 MAY 16.1996. Page*

         bi addition, since the site is a potential brownfield'7 bordered by two railroads, above ground petroleum product storage
 tanks, warehouses and other light industries, future residential development is unlikely.  Therefore, inadvertent ingestion and
 direct contact with surface soils by future residents is also unlikely. Furthermore, as previously mentioned, the notice recorded
 pursuant to the AOC states that residential land use is inappropriate.  Therefore, this pathway does not present an unacceptable
 risk to hur^ar health and the environment
         The Iburth exposure pathway,  'inadvertent ihgestion and direct contact with rurfacr >oils by on-site commercial
 occupants"" is the most realistic and probable exposure pathway. However, this pathway cart be severed with a concrete cap
 covering all known contaminated areas, effectively severing the contaminant exposure pathway  for on-siur commercial
 occupants. Consequently. EPA believes that a concrete cap will be protective of human health and the environment, and as long
 as the cap remains in place the risk will remain less than 1 x 10"* because there will not be an exposure pathway.
         EPA does not anticipate population growth within die area because this area of Houston is "built out** indicating thai
 population growth has mostly peaked. Access from two major freeways. IH 610. and U.S. 59 make the site ideal for continued
 trucking terminal operations. Furthermore, an administrative order on consent provides an institutional control to discourage
 residential land use.
         Lastly, the site's location within an existing industrial corridor, bordered by railroad tracks and next door to a fuel
 distributor as well  as a meat rendering plant, most likely will ensure the site will remain industrial. Consequently. EPA
 concluded that unrestricted site use is not probable and since there is no principal mreat on site, EPA no longer believes
 treatment is appropriate because it can not cost effectively achieve EPA's remediation goals. Therefore. EPA has amended the
 ROD for this site because it believes die BEI arguments for covering the contaminated areas with a concrete cap have merit.1*
        To summarize the reasons for amending the ROD. the soil washing pilot study did not conclude that soil washing would
 provide overall protection of human health and the environment because  the pilot test demonstrated that forty percent of the
 soil volume could not be washed to meet die remedial goal Instead. BEI proposed permanently covering contaminated areas
 with a concrete cap. EPA evaluated the land use and concluded (hat given the current and most reasonably anticipated land
 use, the concrete cap could adequately protect human health and die environment by severing exposure pathways.
 3.      DESCRIPTION OF THE NEW ALTERNATIVE. The concrete cap described in this Amended ROD will seal and
 contain contaminated soils beneath at least six inches of sted reinforced concrete designed to withstand the current and
 anticipated freight truck traffic,
        a.     Design Parameters. To ensure die cap will withstand track traffic EPA will ensure the cap is designed in
 accordance with die design practice specified by Amereart Concrete Institute Code 330. "Guide for Design and Construction
. of Concrete Parking Lots." The cap will be designed to provide positive drainage to eliminate standing rainwater and win cover
 all presently known contaminated surface soils. Site drawings showing the areas requiring cover are included as Appendix B.
 In addition, when the cover is completed a survey plat will be prepared showing the exact location and dimensions of each
 contaminated area  with respect to premanendy surveyed benchmarks.  The plat must be prepared by and certified by a
 professional land surveyor. The plat will  become part of the institutional control used to alert subsequent owners that
 contamination is left on site.
     •   Although the concrete cap will not treat contaminated soil  it will provide a barrier preventing on site commercial
 occupants from inadvertently ingesting, inhaling or directly contacting contaminated soik.
        b.     Closure and Post Closure Care. As pan of die remedy closure and post closure care will be provided. Closure
 and post closure care includes the 40 CFR  §264.119(bXIMiii) requirement cited in Table 3 and those requirements in die
 following paragraphs.
 " A brownfield is an abandoned, idled or under-used industrial and commercial facility where expansion or redevelopment
 is complicated by real or perceived environmental contamination.

               i.      Groundwaier Monitoring System.  In accordance
 with the original Record of Decision, if the monitoring system indicates
 that contaminants  left in place are leaching from the soils now under
 existing  structures  EPA will have to determine if further remediation is
 necessary.^ Consequently, the current groundwater remedial action must
 consider the effects of leaving this soil contamination in place and ensure
 it does not adversely affect the selected groundu-ater remedy.
               n.      Post Closure Plan. After the contaminated soils
 are covered a post closure plan that describes the maintenance activities*
 that will be carried on after the contaminated soils are covered will be
 prepared and executed.
 4.      MAJOR  ARAR'S.   CERCLA, Section  121(dX2) requires
 temediai actions to at (cast attain ARAR's. 42  U.S.C § 9621(dX2).
 Applicable requirements are those cleanup standards, standards of control
 and other substantive environmental protection requirements, criteria, or
 limitations promulgated under Federal  or  State law that specifically
 address  a hazardous substance at a Superfund  site.   Relevant  and
 appropriate requirements are standards, which while not 'applicable" at a
 CERCLA site, address problems or situations sufficiently similar to those
 encountered at the site that their use is warranted. EPA recognizes the
 tfiree ARAR categories defined in Table 1 While EPA does not believe
 (here are any requirements applicable to the remedy outlined in  this
   1 Chemical Specific.  Those requirements
    which establish the acceptable amount or
    concentration of a chemical that may be
    found in. or discharged to the  ambient
    environment

Amended ROD. the requirements in Table 3 are relevant and appropriate.
5.     EVALUATION OF ALTERNATIVES. To properly consider a ROD amendment EPA has traditionally evaluated
(he originally selected remedy and the amended remedy by comparing them against the nine criteria identified in Table 4 to
ensure that the amended remedy reflects the scope, purpose and a long term comprehensive response for the  MIC after
discovering significant new information to support an amendment.-'' In addition, in the case of this Amended ROD. EPA also
considered the presumptive remedies described in "Presumptive Remedies for Soils. Sediments, and Sludges at Wood Treater
Sites." EPA/5407R-95/I2*.
       a.      Overall Protection of Human Health and the Environment. The concrete cap will adequately protect human
health and (he environment by severing the most realistic and probable exposure pathway: inadvertent ingestion ant! direct
contact with surface soils by on-site commercial occupants. Consequently, as long as the land use remains similar to the present
use and the concrete cap remains in place, the amended remedy will be protective, cost effective and efficient. Since the soil
washing  pilot test  study did not conclude that soil washing would provide overall protection of human health .md the
environment as described above, capping provides greater overall protection than the remedy selected in the ROD.

        b.      Compliance With Applicable or Relevant and Appropriate Requirements. It is possible to construct a concrete
 cap which will meet the requirements of the ARAR's identified above which require the remedy to minimize the need for further
 maintenance and control post-closure escape of hazardous waste, hazardous constituents, leachate. contaminated run-off, or

        d.     Reduction of Toxicitv. Mobility or Volume Through Treatment. While EPA recognizes this criteria applies
 only to treatment, a concrete cap will reduce toxkiry by severing the most likely potential exposure pathway.  In addition, since
 water is  the only medium most likely to mobilize the contaminant, a concrete cap will greatly reduce die amount of water
 contacting the contaminant. Although the remedy does not provide soil treatment, since EPA believes mat the current land use.

 benefit.
       e.     Short-Term Effectiveness.  When compared to the originally selected remedy, the amended remedy will provide
 equal or better short-term effectiveness.  With either remedy there is. albeit small, a probability that remedial action workers
 could receive a harmful exposure from fugitive dust  generated during construction.  However, this potential threat will be
 minimized by implementing appropriate worker health  and safety procedures.  Constructing die originally selected remedy was.
 expected to take up to five years, whereas constructing a concrete cap is expected to take less than one year.
       f.      hnplementdbilitv.  In comparison to the originally 'ttected remedy, die concrete cap is impiementable whereas
 soil washing was not impiementable. Although the feasibility i-t-jdy indicated soil washing was impiementable, the full scale
 pilot test demonstrated that soil washing could not consistently and efficiently meet remediation goals. The amended remedy
 is impiementable since it is easy to construct with readily available skills and materials, and is reliable and is easy to maintain.
       g.     Cost.  When comparing present worth costs constructing a concrete cap will cost approximately S697.000
 whereas the soil washing is currently estimated to cost in excess of S6.800.000. There will be no operation costs associated
 with the concrete cap. Since the cap will serve as truck terminal pavement the fact that die cap covers contaminated soil will
 not add to the pavement maintenance normally required for terminal operations. Therefore operation and maintenance are not
 considered in the cost of this concrete cap.
       The originally selected remedy did little to control clean up cost. As demonstrated during the soil washing pilot project.
 successful treatment was uncertain because die final volume and disposal of remaining contaminated soil could not be estimated
 with any acceptable certainty. Uncertainty increases the financial risk for contractors bidding the remedial work, and srcjter
 financial risks will increase the bid price.  By eliminating the uncertainly of treatment success, the financial risk is reduced and
costs are kept under control

remedy. Consequently, a cap will encourage economic development by returning the property to its full potential.

 originally used to calculate the number of sample  collected,  BEI
 vill consider  the  average  soil  pile  concentration  above  the
 remedial action level and BEI vill  wash the entire soil pile.   In
 either  case  if field  standard deviation is  greater  than  that
 originally used to calculate tne number of samples  required,  BEI
 vill recalculate the number of samples using the field  standard
 deviation.    BEI  vill  continue  sampling  until  a  field  sample
 standard deviation correlates with the number of samples  collected.
 Once no additional samples are required, BEI can assume  the  sample
 average  is the average soil pile concentration and use the average
 to determine if  the pile requires r*oedlal action.

 Dear Mr.  Radel:

      Ibis letter is in response to Beazer'a August 18,  1995,
 latter and the August 28,  1995,  meeting between KPA and Beazer.
 As  discussed in  the August 8,  1995, KPA letter to  Beazer,  the
 consent decree executed by Beazer on or about  June 11,  199O,
 gives SPA the authority to pursue further investigation to ensure
 that  human health is protected from an actual  release of a
 hazardous substance (CD p.  2).   Current aite conditions give  EPA
 reason to believe that there may be additional contamination
 deeper than shown in the August  1992 soil delineation study.
 However,  if there is little chance that humans will actually  be>
 exposed to  contaminated soils deeper than two  feet below th*
 ground surface, EPA is willing to reconsider the risk those)
 deeper contaminated soils pose to human health.

     Although EPA la willing to  reconsider the risk posed  by
 potentially contaminated soils deeper than two feet, in ih«
 Consent Decree, Appendix I, Statement of Work,  EPA represented to
 the public  and current landowners that contaminated sell would be
 remediated  to a maximum depth of eix feet; therefore, the  EPA
muat notify the public that it may not continue remedial action
below two feet.   Consequently, EPA intends to  notify the public
of its decision to cease excavation at two  *eet rather  than at
aix.

     EPA will consider public comments when it determin«a  if
there are unforeseen risks  to human health  from any contamination
deeper than two feet.   If,  after reviewing  any public comments,
 EPA determines that there  is minimal risk to human health  posed
 by contamination  two feat deep,  EPA will instruct  Beazer to
 commence excavation.

-------
     Lastly, since EPA  is considering changes  to  the  remedial
action it agrees to suspend the current construction  schedule
until it determines if  there is any need to further pursue
investigating soil contamination below two feet.

     If you have any questions please call me  at  (214) 665-8523.

                                   Sincerely,

 Re    Contemplated Soil Remedial Action Revision
       South Cavalcade CERCLA Site
       Houston, Texas
Dear Glenn:

This letter has been prepared in response to the United State's Environmental Protection
Agency's (EPA) letter of September 7, 1995 regarding EPA's  contemplated revision to the
soil  remedy at the South Cavalcade CERCLA Site (Site) located in Houston, Texas.
Specifically, EPA, stales in the subject letter that "if there is little chance that humans will
actually be exposed to contaminated soils deeper than two feet below the ground surface,
EPA is  willing to  reconsider the  risk those deeper contaminated soils pose to  human
health." Further, EPA "intends to notify the public of its decision to cease excavation at two
feet Bather than at Six" in order to inform the public of changes in the soil remedy and allow
public comment   If EPA determines after a review of public comments "that there  is
minimal risk to human health posed  by contamination  two feet deep, EPA will instruct
Beazer to commence excavation."

Beazer agrees with the EPA that soils at or near the ground surface represent the greatest
potential exposure  pathway to on-site commercial workers.  Therefore, EPA's above
referenced  recommendation will mitigate the potential  risk of exposure to these surface
soils. However, Beazer believes that an alternate approach will effectively mitigate this
potential risk of exposure as well or better than EPA's recommended alternative  This
approach consists of a concrete cover over the identified areas of concern. The concrete cap
will  in fact be more protective  than EPA's alternative because a permanent, impermeable
barrier will be constructed in  the designated areas of concern.  This approach is also
consistent with EPA's determination that the existing pavement and buildings effectively
mitigate potential exposure to  soils beneath these barriers.  The following constitutes a

-------
 Page 2
 Mr. Glenn Cderier
 September 27,  1995

 summary of  the primary issues which  support  Beazer's  recommendation  to install  a
 concrete cover in the designated areas of concern.

 Beazer believes that surface soils, defined in the ROD as the "upper six inches of soil"
 constitute the primary risk to human health, not a'l soils within the two foot depth as stated
 in LPA's September 1,1995 letter. The Final Puouc Health and Environmental Assessment
 ("Risk Assessment", August 1968) identified the primary soil exposure pathways  for the
 Site as dermal contact and inadvertent ingestion  for on-site commercial occupants and
 utility workers (see below). It is unlikely that on-sifc commercial occupants win ever be
 exposed to COCs below six inches in depth via the principal exposure pathways of direct
 contact with  soils  and  ingestion.    On-site commercial  activities include primarily
 tractor/trailer rig storage, loading and unloading. Therefore, on-site occupants would not
 be exposed to soils below six  inches in depth during normal day-to-day activities. Only
 invasive activities at the Site related to  the installation of structures and  supporting
 underground utilities would potentially expose on-site construction workers to impacted
 soils below six inches in depth. Accordingly, Beazer believes that the primary risks to on-
 site commercial occupants and construction workers is limited to the upper six inches of
 soil. Excavating an additional eighteen inches to the two foot level provides no additional
 reduction in risk yet adds significant increase ii cost

The  principal  exposure pathways and human  receptors were identified in the Risk
Assessment and summarized in the ROD.  The mitigation of human health risks via the
identified  exposure pathways for EPA's contemplated  soil remedial  alternative  and
Beazer's proposed concrete capping remedy is summarized below.  For each exposure
pathway, Beazer's proposed alternative, concrete capping, is equally or more protective
than EPA's contemplated alternative

•  Inadvertent ingestion and direct contact with surface soils by on-site commercial
   occupants.  The risks associated  with  impacted rirface sods to on-site commercial
   occupants is  primarily related to contact with airborne dust or with  surface soils
   impacted with potentially carcinogenic potynudear aromatic hydrocarbons (pcPAHs)
   and ingestion of these constituents. EPA's proposed remedy eliminates direct contact
   with soil to a depth of two feet However, the Risk Assessment did not foresee any risk
   via this exposure pathway for soils deeper than six inches. Beazer's proposed concrete
   cap remedy removes any risk associated with this exposure pathway by providing a
   physical barrier to human contact

•  Inadvertent ingestion and  direct contact with drainage ditch  sediments  by
   trespassing children.   The  primary  transport  mechanism  for migration of  soils
   impacted with pcPAHs is  sediment  in stonnwater runoff. Through excavation and
   treatment of soil to'two fleet EPA's contemplated alternative remedy would eliminate
   the migration of any impacted surface soils in stonnwater sediments. However, soils
   below six inches in depth are not susceptible to stonnwater runoff. Beazer's proposed

-------
 Page 3
 Mr. Gienn Cderier
 September 27, 1995

    concrete cap eliminates storm wa^er contact with surface  soils  thus eliminating  the
    transport mechanism and associated risks for this exposure pathway.

 •   Inadvertent ingestion, dost inhalation, and direct contact with smfitial  soils by
    utility or construction workers. The Risk Assessment addresses risks associated with
    future construction worker invasive activities such as new construction and associated
    utility installation which may expose workers to surfkial soils impacted with pcPAHs.
    By providing a robust barrier which must  be broken prior to any invasive work,
    Beazer's proposed concrete cap remedy is more protective of human health via this
    exposure pathway than EPA's proposed two foot excavation remedy.  Both proposed
    remedies also rely on using institutional  controls, as referenced in the HOD and
    recommended in EPA's Land Use Directive (OSWER Directive No. 9355.7-04; Land Use
    in the CERCLA Remedy Selection Process), to control these risks.

    The ROD already provides for institutional controls to minimize the potential exposure
    to Site construction workers. EPA requires that "site owners add a notice to their deeds
   expressing that hazardous substances are located under concrete and buildings.  EPA
   will require this to notify any potential  purchaser of the Site about this contamination"
   (Page A-7 of the ROD). This notice can be modified to include areas of the Site that
   Beazer proposes to cap.  The ROD  and the Consent Decree further  require that
   landowners provide notification to EPA of any proposed development in any area
   containing impacted soil Further, access agreements are in-place between Beazer and
   all the Site landowners, and this agreement requires landowners to notify Beazer of any
   development at the Site which may involve invasive activities in impacted areas of the
   Site;

»  Inadvertent ingestion and direct contact with surface soils by future residents if the
   site is ever developed. As stated in the Land  Use Directive, EPA expects that the vast
   majority  of Superfund sites will continue to be used as industrial sites.  Future
   residential use at the South Cavalcade Site is highly unlikely. All three parcels of land at
   the Site are being used for trucking operations and it is expected that this type of land
   use will continue  In fact NW Nations Way Transport Service, Inc. recently purchased
   the Site's northern tract from the Baptist Foundation of Texas with plans to expand the
   trucking  terminal.  Additionally, industrial sites surround nearly the entire 64-acre
   South Cavalcade  Site, and  active  railroad  tracks  border  both the east and  west
   boundaries, making it extremely unlikely a  tract of land such as this will  ever be
   developed for residential use Deed restrictions can be obtained from the land owners
   which win allow  only future indusbial/commerdal utilization of  the Site.   Both
   Beazer's  proposed capping  and EPA's proposed two  foot excavation  soil remedies
   properly assume continued commercial/ industrial use of the Site, acknowledging the
   insignificantly small risk associated  with this exposure pathway.

»  Ingestion of groundwater if contamination continues to migrate or if water supply
   wells are ever installed on-site.  Beazer has shown in extensive testing and analysis of

-------
 Page 4
 Mr. CHenn Celerier
 September 27. 1995

    soil leaching potential that the COCs in the Site soils do not leach,  To support the
    absence of risk to groundwater presented by leaving impacted soils in-place, over 250
    soil samples have been collected and analyzed using TCLP to determine any leaching
    potential for soils impacted with pcPAHs. None of the more than 250 samples analyzed
    have shown leaching potential Thus, diere exists no risk of impact to groundwater
    associated with leaving any impacted soil in-place at the Site.  The Site constituents
    simply do not  leach from soil  and this risk exposure pathway is  a  non-issue for
    impacted soil

    Further, the Site and surrounding areas are provided city water and water supply wells
    are not required or Jesirabie.

    Beazer's proposed concrete cap remedy  provides even  further  assurance that this
    exposure pathway is  a  non-issue for impacted soil at  the site by providing an
   * impermeable barrier to rainfall infiltration.  By removing the transport mechanism, the
    concrete cap eliminates all arguable risks, if any,  that could be associated with this
    exposure pathway.

Beazer's proposed concrete cap would provide many benefits  beyond those provided by
EPA's proposed two foot excavation remedy. They  include  consistency with the ROD-
seJected soil remedy for existing paved areas of the  Site, reduction of the time frame for
implementation of  the soil remedy, elimination of potential exposure  to construction
workers during implementation of the soil remedy, and allowance of minimum disruption
to ongoing trucking operations while more promptly providing hppgfiriaj land use to the
community in full compliance with EPA's Land Use Directive Each of these additional
benefits are discussed below.

•   Establish 9 consistent soil remedy throughout the Site.  In the ROD, approximately
    60%  of potentially impacted soils were noted to  be present beneath existing concrete
    and buildings in the southeast portion of the Site based on data collected during the RL
    Per the ROD, these areas do not require remediation because the risks of dermal contact
    or inadvertent  ingestion  are mitigated by  the  barrier (the  buildings  anu  paving)
    between occupants and the impacted soiL  Likewise, placing Beazer's proposed concrete
    cap over the remaining impacted areas provides  the same mitigation of risk to on-site
   Qimtnate  potential  expocnrc  to  construction  woocen  """"g  sou  remedy
   implementation. The EPA's proposed revision to this remedy win require excavation,
   handling, hauling and processing of impacted soils; storm water run-on and  runoff
   control and treatment and  residual  materials handling and disposal,   m addition,
   residual materials may require off-site disposal at an approved TSD facility, and there
   are additional risks of human exposure during loading, transportation, off-loading,
   disposal and decontamination activities.

-------
 PageS
 Mr. CHenn Cdeher
 September 27, 1995

    Beazer's proposed cap will practically eliminate these risks. Nearly all areas of the
    proposed cap will be designed for installation at or above the existing exposed ground
    surface, therefore, invasive activities will ve limited.  Dust control measures will be
    implemented to ensure a minimal amount of worker exposure during construction of
    the concrete cap.

 •  Reduce the time frame for soil remedy complet' ~m and provide beneficul land use
    for the community.  The cap remedy is consistent with the ROD and EPA's Land Use
    Directive in  p.uviding a preference for continued  beneficial use of the property.
    Implementation of the current remedy and EPA's revision of this  remedy will require a
    one to two acre Site area for the construction and  operation of  the EPA approved
    bioremediation cells.  Bioremediation of impacted Site soils pursuant to EPA's proposed
    two foot excavation remedy may take up to five years to complete. During this time
    frame, the one to two acre bioremediation cell area will be unusable.  Capping of the
    impacted soil areas pursuant to Beazer's proposed remedy will require only months to
    complete thereby greatly  reducing remedial operations related exposure  risk and
    promptly placing the Site back into a productive and beneficial commerciai/industrial
    use.

    Beazer's proposed concrete cap has the additional benefit of providing a structure
    which enhances the use of the Site for trucking operations.  EPA's Land Use Directive
    considers land use in  making remedy selections under CERCLA and can be applied to
    remedy modifications as  well.  EPA acknowledges in this guidance the importance of
    continued land use in remedy selection.  As stated on Page 1 of the Land Use Directive,
    "EPA acknowledges the  importance of lanJ  use  in determining cleanup levels and
    remedies...   and  expects  that   the  vast  majority   of sites  with   current
    industrial/commercial uses (70% of all  Sup°rfund sites) will continue to be used as
    commercial or industrial  sites...".   Beazer's proposed concrete cap remedy provides
    beneficial continued  commercial/industrial  utilization of the Site  to the maximum
    extent possible while minimizing risks to human health and the environment

In conclusion, Beazer supports EPA in its effort to effectively mitigate risks at the Site and to
minimize the time frame required for soil  remediation.  While  EPA's  proposed  two foot
excavation soil remedy effectively addresses all contemplated risks to Site occupants and
construction workers, Beazer's proposed capping remedy provides equal or improved risk
reduction and the  additional benefits associated  with a more prompt efficient and
consistent remedy as described above.  The ROD already acknowledges the equal to  or
unproved risk  reduction provided by concrete capping through its allowance for leaving
impacted soils  in-place at the Site  under existing concrete and buildings.  Further, legally
binding documentation in the form of deed restrictions, as referenced in the ROD, access
agreements,  the ROD,   and the  Consent Decree  require that land owners  provide
notification to EPA and Beazer of any invasive activities that may conceivably disrupt the
integrity of such a cap. Finally, Beazer has already implemented an extensive groundwater
remediation and monitoring program at the Site and will closely monitor the progress of

-------

groundwater remediation at the Site to ensun» that the remaining exposure pathway, if any,
is controlled.

Beazer agrees with EPA that revisions such as those discussed herein will require public
notification and comment   Beazer is confident that afl community cunnans can  be
addressed promptly and adequately and will provide EPA with any support required. We
look forward to EPA's positive response to Beazer's proposed concrete cap.

RE: Contemplated Soil Remedial Action Revision, South Cavalcade
Superfund Site, Beazer Ltr dated September 29, 1995

Dear Mr. Slenska:

     We reviewed the referenced letter in which Bedzer proposes capping
"areas of concern" with concrete and believe the proposal has merit
However, before we can consider this proposal further we would like
additional information. Consequently, we request Beazer provide the
following information:

           -  Define the "area of concern" referenced in Beazer's letter

           -  Provide a conceptual cap design (plan and cross section
           dimensions, location, general specifications, and construction
           quality assurance)

                                  RE    Concurrence with Site Capping
                                         South Cavalcade CERCLA Site
                                         Houston, Texas
 Dear Monte
This letter is a follow-up to our telephone conversation during the last week of September, 1995,
in which we discussed the possibility of placing a concrete cover over the impacted soil areas of
the South Cavalcade CERCLA Site (Site)  As we discussed, this concrete cover would be in lieu
of bioremediation for the impacted Site soils.  This letter is intended to confirm in writing your
verbal concurrence with the proposed concrete cover as a modified soil remedial action.

On Sept. 29,  1995 Beazer East, Inc. (Beazer) submitted a letter to the United States
Environmental Pr•••>. Action Agency (EPA) which sets forth the risk analysis and rationale in
support of concrete capping as the most cost effective and preferred alternative soil remedy for
the Site  That letter is attached for your review.  In response to Beazer's submittai, the EPA
requested that we provide additional information concerning the proposed concrete cap.  EPA's
Oct. 5, 1995 request ietter is also attached for your review.  Included in the EPA letter U a
request that Beazer "Provide assurance that the land owners do not object to a cap in lieu of
bioremediation."

There are two impacted soil zones located on the grassy area just south of the maintenance shop
on Nations  Way Transport Service, Inc. (Nations Way) property which cover a total area of
approximately 1,750-square feet.  As we discussed, this is a relatively small area and Beazer
believes that the most appropriate remedial action may be to excavate and dispose of this material
ai an oIT-sue disposal facility  However, this remedial option for the soils on your property has
not been finalized. In the event that alternate plans are necessary, Beazer will develop plans and
specifications to place a concrete cover over the impacted soil areas at an elevation above the
existing grades

Beazer is preparing a conceptual design submittai to provide the EPA with the requested
additional information, and in that submittai Beazer will propose excavation and off-site disposal

-------
for the impacted soils on your property.  However, should the EPA require the concrete cover to
be placed over all impacted soil areas, the conceptual design will be revised to include sketches of
the concrete cover arrangement consistent with the configuration described above. Additionally,
it is Beazer's hope to include the above referenced assurance of landowner concurrence with the
conceptual design submittal.

Beazer believes that the signed Access Agreement alread" in existence between Beazer and Nations
Way provides any requisite authorization needed for Beazer to implement the Record of Decision
(ROD) selected remedy, whether amended or modified to provide for alternative remedial action such
as conciete capping. Nevertheless, as a courtesy to Nations Way, and in order for Beazer to provide
to EPA the above noted assurance, and to ensure that open communications are maintained between
Beazer and Nations Way, Beazer is forwarding this request for written confirmation of our previous
discussions. To confirm your pi .or verbal  concurrence »ith using an alternative soil remediation plan,
including excavation and off-site disposal or a concrete concrete cover, in lieu of bioremediation please
sign on the space provided below and return the original to my attention using the enclosed self-
addressed overnight envelope, retaining a copy for your files. A copy of this sighed letter will be
included in  our conceptual concrete coyer  design suunrittai to the EPA, Should Beazer receive EPA
approval to proceed with a detailed design of the concrete cover, or excavation and "ff-site
disposal of the impacted soils on your property. Beazer will work with Nations Way to
accommodate any reasonable comments  or concerns regarding the  design.

If you should have any questions or require additional information please contact me at (412) 227-
2174.

Dear Bob:
This letter is a follow-up to our Sept. 21, 1995 meeting in which we discussed the
possibility of placing a concrete cover over the impacted soil areas of the South Cavalcade
CERCLA Site (Site)  As we discussed, this concrete cover would be in lieu of

United States Environmental Protection Agency (EPA) which sets forth the risk analysis
and rationale in support of concrete capping as the most cost effective and preferred

also attached for your review. Included in the EPA letter is a request that Beazer
"Provide assurance that the land owners do not object to a cap in lieu of bioremediation."

For the impacted soil areas located on Trucking Properties, Inc. (TPI) property the
concrete cap would cover approximately sixty percent of the small grassy area located just
south of the warehouse.  We anticipate that the concrete cover would be placed above the
existing grades in this area, and would include a small ramp making the cover accessible
for personal vehicle parking.

-------
 Beazer is preparing a conceptual design submitul to provide the EPA with the requested
 additional information.  This conceptual design will include sketches of the concrete cover
 arrangement consistent with the configuration described above  Additionally, it is
 Beazer's hope to include the above referenced assurance of landowner concurrence with
 the conceptual design submittal.

 Beazer bdieves that the signed Access Agreement already in existence between Beazer and
 TPI provides any requisite authorization needed for Beazer to implement the ROD selected
 remedy, whether amended or modified to provide for an alternative remedial action such as
 concrete capping. Nevertheless, as a courtesy to TPI, and in order for Beazer to provide to
 EPA the above noted assurance, and to ensure tliat open communications are maintained
 between Beazer and TPI. Beazer is forwarding this request for written confirmation of ~ur
 previous discussions.  TV. confirm your prior verbal concurrence with using a concrete cover ir
 lieu of bioremediation please sign on the space provided below and return the original to my
 attention using the enclosed self-addressed overnight envelope, retaining a copy for your files.
 A copy of this signed lettsr will be included in our conceptual concrete cover design submittal
 to the EPA.  Should Beazer receive EPA approval to proceed with a detailed design of the
 concrete cover, Beazer will work with TPI to accommodate any reasonable comments or
 concerns regarding the design.

       Re:   South Cavalcade CERCLA Site, Houston, Texas
             Property Owner Consent to Concrete Capping Proposal

Dear Mr. Celerier:

       Beazer East, Inc. has provided us with a cooy of the final conceptual design report for
its proposal of concrete capping as the remedy for contamination located on our property at the
South Cavalcade CERCLA site in Houston, Texas. Beazer East, Inc. has asked us to give you
our written consent to the concept of concrete capping.  Our concerns about the proposal can
be grouped generally into two types of issues, one of which is whether the proposal protects
human health and the environment,  and the other of  which is how the new cap will affect the
use and enjoyment of our property long term.

       Based on my telephone conversations  with  you previously, we understand  thai the
Environmental Protection Agency will appi  ve the concrete capping proposal as a remedy for
this CET.CLA site oniy if you conclude tLtt this remedy will protect human health and the
environment as long as the contamination remains on this property. Therefore, we are deferring
to the Agency with regards to these health and environmental considerations.

       Beazer has given us certain assurances that it will address our other concerns about the
concrete capping proposal, relating to the impact of the new concrete cap on a permanent basis
as it affects our existing improvements and the operations on our property, by incorporating our
reasonable comments and modifications  into the final design, plans and specifications for the
concrete cap, and by accommodating us on various issues relating generally to the construction
process.  In reliance upon those assurances,  we are  giving you this letter as evidence of our
consent to the concept of concrete capping as a remedy for the contamination existing on this
property.

APPENDIX B - CONCEPTUAL DESIGN OF CONCRETE CAP
       SOUTH CAVALCADE SUPERFUND SITE

-------
                              1.0  INTRODUCTION

 On September  29, 1995, Beazer East,  Inc. (Beazer) submitted a letter to the United  States
 Environmental  Protection Agency (EPA) which describes the risk analysis and rationale in
 support of concrete capping as the most cost effective and preferred alternative soil remedy for
 the South Cavalcade CERCLA Site (Site) located in Iloustcn, Texas. On October J, 1995, in
 response to Beazer 's submittal, the EPA requested that Beazer provide additional information
 concerning the  proposed concrete cover.

 This Conceptual Design Report presents the requested additional information and includes: a
 general description of the proposed concrete cover configuration including preliminary drawings
 and  specifications, a discussion  of the additional tasks required to complete the proposed
 concrete cover detailed design, an economic evaluation comparing the proposed concrete  cover
 to washing of the Site soils, documentation of property owner concurrence with using a concrete
 cap  in lieu of  ROD  selected soil remedies, and  a preliminary  schedule for the design and
 construction of the proposed concrete cover.

                          2.0   CONCEPTUAL DESIGN

 Beazer has developed  a  conceptual design configuration for each of the four  main soil
 remediation areas of the Site. These four main areas, as shown on Figure 1 , are the Southeast,
 Southwest, and Northeast Areas  and the Groundwater Treatment Plant Area  of the Site as
 described in the Soil Remedial Design - 100% Design Submittal, Dames & Moore, December,
 1994.  Several specific design criteria  were used to develop the  proposed concrete cover
 conceptual designs for  each of the four soil remediation areas.  These design criteria are
presented below:

       •   Cover the Impacted  Zones - As  determined by  the recently completed soil
          Confinnational Sampling Program, the impacted soil zones have been delineated and
          confirmed for each of the four main areas. The proposed concrete cover should, at
          a minitpupt  cover at least these impacted zones.
          Provide a Useable Concrete Cover - The concrete cover should be designed to allow
          use of the covered areas which is consistent with the current property operations.

-------
                     Impacted Soil  Excavation - The design should minimiyg the amount of
           impacted soil requiring excavation during construction of the concrete cover.  Any
           cut and fill required for construction of the concrete cap should achieve a balance
           such that excavated impacted material can be placed as fill over other impacted zones
           thereby limiting the need for off-site disposal of impacted material.

       •   Provide Adequate Drainage -  The surface contours of the concrete cover rhould
           provide for positive drainage of the cover, and wherever possible remain consistent
           with the existing drain^e patterns of the Silt.

The following discussion presents the concrete cover conceptual design for each of the four Site
areas described above.

2.1  SOUTHEAST AREA

The Southeast Area is a narrow strip of land located on the east side of Palletized Trucking,  inc.
(Palletized) property.  There are six impacted soil zones in this area which cover a total area of
approximately 35,500 square feet.

The existing surface  of the  Southeast  Area consists of an assortment of materials, but is
predominantly  covered  with crushed concrete.   Material  excavated during Coafirmational
Si,.,.pling Plan (CSP) activities was  backfilled with no nechanral compaction and presently
exists in  a  loose  state,  while  material not disturbed  by CSP activities  remains in a well
compacted state.

The Southeast Area is relatively flat with slightly higher elevations located approximately in the
middle of this narrow area. This high point divides the Southeast Area into  northern  and
southern drainage areas.  Both areas have a general easterly slope; therefore, runoff from these
areas flows to the  HB&T Railway ditch located to the east of the Site.  In addition to its own
surface runoff, the northern drainage area includes surface runoff  from the easterly sloping
existing concrete located to the west of this area.

2.1.1 Concrete Cover Configuration

The concrete cap for the Southeast Area will cover the majority of the narrow strip of land on
the east side of Palletized  property,  which will provide a suitable  tarmac for truck use.  The
general layout for the concrete cover is shown in Figure 2. Additional details for the Southeast
Area concrete cover are shown in Figures 3 and 4.  The following text describes  bow the
concrete cover configuration shown in Figures 2, 3, and 4 satisfies the design criteria described
above in Section 2.0.

      •      v
          -  To provide Palletized with a continuous pavement for operations the concrete cap
             will be constructed over both impacted and nonimpacted zones.

      •   Provide a Useable Concrete Cover

          -  The slope of the concrete tarmac will be minimal to enable trailers to be parked.
          -  Abrupt changes in grades will be avoided. Grade transitions will be achieved by
             utilizing ramps as shown in Figure 5.
          -  The concrete cap will be wide enough along the entire length to accommodate
             Palletized's trailer sizes of 40 and 48 feet lengths.
                        %

                            Soil Excavation
          -  Cross-Section A as shown in Figur*  3  is a  typical cut section.   Impacted
             excavation from this area will be placed as fill material  over other imparted
             zones.  Cross-Section A is typical of approximately 20 percent of the Southeast
             Area.
          •  Cross-Section- B as shown in Figure 3  is a typical fill section.  Excavation of
             impacted or nonimpacted material  is expected not to be required in the fill
             sections. Cross-Section B is typical of approximately 80 percent of the Southeast
             Area.
          •  Cross-Section C as shown in Figure 3 is cut through all the Southeast impartrrl
             zones.   Inspection of mis cross-section reveals the volume  of fill within die
                      zones  is greater than the expected volume of imrMr'*'5 excavation.

-------
-  Earthwork quantities associated with the presented cross-sections are as follows:

          Fill Required Over Impacted Zones	   510 cubic yards
          Cut Required Over Impacted Zones	93 cubic yards
          Balance	417 cubic yards of fill

          Fill Required Over Nonimpacted Zones	   680 cubic yards
          Cut required Over Nonimpacted Zones	   170 cubic yards
          Balance	510 cubic yards of fill

   The reported quantities are approximate and are subject to slight modifications
   during final  design.
•  The existing soil stockpiles located onsite will be used as fill material.  These
   stockpiles have been tested following the methods contained in the EPA approved
   Stockpile Sampling Plan,  included a:, pan  of Appendix A-l  of the  Remedial
   Action Work Plan.  Test results have demonstrated  that these soil stockpiles do
   not contain potentially carcinogenic polynuclear aromatic hydrocarbons (pcPAHs)
   above the Record of Decision (ROD) goal of 700 ppm.
-  The impacted soil excavated in the Northeast Area will be used as fill over  the
   impacted zones of the Southeast Area.

Provide Adequate Drainage

-  In the northern drainage area runoff from the existing westerly concrete pavement
   will be intercepted at the constructed ramp and directed to the north end of  the
   cap or to a drainage swale formed into the cap -s shown on Figure ? and Cross-
   section C of Figure 3.
-  In the northern drainage area the concrete cap will have a cross drainage slope
   to the east which will flow into a swale formed into the cap as shown on Cross-
   section A and B  of Figure 3.  The runoff from the northern end of die cap will
   be directed to an  unpaved area in die northeast corner of Palletized and ultimately
   routed to the existing HB&T Railway ditch.
-  In the southern drainage area the concrete cap will  have a cross drainage slope
   to the east which will flow into a swale formed into the cap as shown  on Cross-
   section A and B  of Figure 3.  The runoff from die southern end of die cap will

              cap in the southeast corner of Palletized.
 2.1.2  Concrete
 Due to the nature of properly designed and constructed concn.c pavements iMintemneg for the
 proposed cap will be limited. By designing properly spaced expansion joints in the concrete cap
 cracking of the cap will be controlled at the joints.  Expected minimi^ joint spacing is 1 J to
 25 feet.  The expansion joints will be designed to be liquid tight to minimiM- infiltration of storm
 water.

 2.2  SOUTHWEST AREA

 The Southwest Area is a relatively square piece of land located at the south entrance of Trucking
 Properties. Inc. (TPI) property.  There are two impacted soil zones in this area which cover a
 total area of approximately 8,300 square feet.

 The existing surface of ihe  Southwest  Area  consists of grass.  Material  excavated  during
 Confinnational Sampling Plan (CSP) activities was backfilled with no mechanical compaction
 and presently exists in a loose state, while material not disturbed by CSP activities remains in
 a well compacted state.

 The Southwest Area is relatively flat with a slight crown ii. the noddle on a north and south axis.
 Drainag- in this area is to the east and west away from the slight crown described above.

2.2.1  Concrete Cover Configuration

The concrete cap for the Southwest Area will cover approximately 60 percent of the square piece
of land located at the south entrance of TPI property. The concrete cap will (unction as suitable
space for future employee parking.  The general layout of the concrete cap is shown  in Figure
6.  Additional details for the Southwest Area concrete cover are shown in Figure 7.  The
 following text describes how the concrete cover configuration shown in Figures 6 and 7 satisfies
the design criteria described above in Section 2.0.

           •  To promote drainage away from the cap in the Southwest Area the cap will be
             constructed at a slightly higher grade but at a slope similar to the existing grade.
             A crown will be formed near the middle of the area and the cap will be sloped
             towards the existing curb whereupon surface runoff will discharge to the existing
             paved areas surrounding the Southwest Area.

2.2.2 Concrete Cover Maintenance

Maintenance for the concrete cap in the Southwest Area will be similar to mat described for the
Southeast Area.          ,

2.3 NORTHEAST AREA

The Northeast Area is a relatively s^we piece of land located north of the maintmince shop
on die eastern side of Nations Way Transport Service, Inc. (Nations Way) property.  There are
two iapacaed soil zones in this area which cover a total of approximately 1.845 square feet.
These two imuarinl zones  result in an in-place volume of approximately 140 cubic yards.
Due 10 Nation Way's expiesaed interest to expand their trucking optrariom. and the relatively
mt". impf***' •»*• ^H moTh!*** tiril "^"Bft in «hf Nimfr^i* ATT*.
appropriate remedial action for this area is to excavate this material and backfill the excavation
with dean fill.  The in place volume of 140 cubic yards of excavated nnpacted material from
die Northeast Area would be used asfill over nnpaoed zoo« in the Southeast Areas.  This will
allow for final remediation of this area without introducing a small cimi'rtt cover which may
evenmaDy need to be incorporated into a larger paved area.

-------
2.4    GROUNDWATER TREATMENT PLANT AREA

The undefined impacted area located on the north and east side of the GWTP. as shown on
Figure 1. will be capped consistent with the type of concrete cover proposed for the Southeast
and Southwest areas. During implementation of ihe detailed design the extent of this area win
be defined, in part, using existing analytical soil data which was previously collected.
                            3.0 DETAILED DESIGN

3.1  ISSUES TO BE RESOLVED

As described in Section 2.0 above there are four design constraints to be addressed as part of
the final design. These design constraints are: cover the impacted zones, provide a useable
concrete cover, minimize impacted soil excavation, and provide adequate drainage. Issues whkh
must be resolved to complete the final design include:

       •  Obtain approval from the EPA of this Conceptual Design Report.

       •  Confirm the proposed ramps in the Southeast and Southwest are suitable for use with
          the expected vehicles.

       •  Assess the existing moisture content and density characteristics of the subgrade
          materials m both the  mipMtpfl and mrnimpacml  zones without performing ait
          extensive mm rove gcocfchmcal uivf uigttioa.

       •  Develop methods to density the by-place materials sufficientry to support me intended
          dead and live loads with minimal disturbance of die subgndet
                         •

       •  Develop pavement design parameter! such at a California Bearing Ratio (CBR) or
          > modulus of subgrade reaction (k) for the  supporting subgrade.
          Determine the thickness, maintaining a minimum tmcknen of six "y*1^*!  and)
                                              rete cap.

      Dear Ms. Balandran:

      Palletized Trucking, Inc. is writing to provide die United States Environmental Protection
      Agency wim comments on the proposed Record of Decision (ROD) Amendm^ which would
      allow die use of concrete capping as a soil remedy at die South Cavalcade Superfund site.

      As yon are aware, we are a property-owner at this site, and have even signed a Consent Order
      with die USEPA regarding this site.  We are very pleased to see the USEPA finally move
      forward with allowing Beazer to place a concrete cap as die final remedy for impacted soils at
      this site. It has been nearly two years since Beazer started full scale remediation activities,
      which required us to vacate a signifkant portion of our traikrosildng area. Vacating mat area
      for such a long period of time has hindered our opcntionsi effickncy and costs us a significant
      sum of money. The delay has also prevented us from proceeding wsth our tire shop
                                            in an area of the proposed concrete cap.

                               ROD Amendment No. 1
    This Responsiveness Summary has been prepared to provide written responses to comments submitted
regard;-ig the Proposed Plan of Action for the South Cavalcade Superfund Site in Houston. Texas.


EPA received public comment for the South Cavalcade Site Proposed Plan during a 30 day comment
period from February 9 through March  12,1997. During that period, EPA received comments from each
land owner and Beazer East Each land owner and Beazer East supported the proposed amendment in
writing.  The landowners' comments are included with this amendment as Appencix E and do not require
a response. Beazer East's comments and EPA's response are provided below. In addition, on February
20, 1997, EPA held a meeting at which the public was allowed to comment on this proposed plan. A
public notice announcing the public comment period and public meeting was printed in the Houston
Chronicle on February 9,1997.   No comments opposing the plan were received from the general public
during the comment period.


Beazer East Inc. Comments


1.  General Comments


    a.  Soil Washing


       Comment: The 1993 Soil Washing Pilot Study conclusively demonstrated that soil washing *ould
       not successfully reduce constituent concentrations to meet the remedial goals in forty percent
       (40%) of the impacted soil. Consequently, the Pilot Study indicated that soil washing would be
       neither protective of human health nor cost-effective. Beazer recommends that the Proposed ROD
       Amendment be revised to more clearly reflect this point Specific suggestions are set forth in the
       Specific Comments section below.


       EPA Response: EPA considered the comment and agrees that the soil washing pilot test failed to
       conclude that soil washing could successfully remediate contaminated soils on site and made
       changes to paragraph 1 .e, and 4.a. to "more clearly reflect this point" However, since soil
       washing cost effectiveness was not the principal criteria for deciding to amend the ROD, EPA
       does not believe a revision is necessary to "more clearly reflect" the reasons for this amendment
       EPA believes it adequately addressed the impact cost-effectiveness had on the decision to amend
       the remedy in Section 5(g) of the ROD Amendment

-------

    b.  Applicable and Relevant and Appropriate Standards ("ARARs")


       Comment: The proposed revised remedial alternative is a cap consisting of at least 6 inches of
       steel reinforced concrete. Beazer concurs with EPA's conclusion that there are no federal or state
       requirements which are applicable to the proposed cap.  However, the draft Proposed Amended
       ROD states that certain requirements contained in 40 CFR Part 264, Standards for Owners and
       Operators of Hazardous Waste Treatment, Storage, and Disposal Facilities, are "relevant and
       appropriate."  The Proposed Amended ROD states that "relevant and appropriate" standards are
       those which address situations or problems sufficiently similar to those encountered at the site that
       their use is warranted.  Beazer does not believe that the hazardous waste regulations listed as
       "relevant and appropriate" address situations or problems sufficiently similar to those at this site,
       given the proposed revised remedy, such that their use is warranted.  Basically, although a concrete
       cap has been proposed for the amended remedy, the remedy is not analogous to those employed to
       accomplish closure of hazardous waste landfills.


       Each of the regulations cited relates to the closure, post-closure and/or post-closure maintenance of
       a hazardous waste disposal facility. Generally speaking, these regulations assume that the media
       surrounding the disposal facility has not been impacted and include measures to prevent and
       monitor the potential for such  an impact In addition, these regulations include technical
       construction standards which have not been proposed or evaluated for this site. For example, one
       of the requirements of 40 CFR §264.310(b), which is one of the sections referenced as "relevant
       and appropriate," is that the owner/operator continue to operate the leachate collection and
       removal system until leachate  is no longer collected. Clearly, such a requirement is not "relevant
       and appropriate" with respect to the Proposed Amended ROD. Moreover, reference to the cited
       sections of the RCRA standards on closure of hazardous waste landfills as "relevant and
       appropriate," is not only incorrect, it may prove confusing to other parties in terms of the
       requirements to be contained in the Amended ROD.


       In sum, Beazer believes that the listed sections of 40 CFR Part 264 are not relevant and
       appropriate standards to the proposed amended soils remedy of this site. Therefore, Beazer
       requests that the Proposed Amended ROD be revise*? by deletion of the reference to these
       regulations as "relevant and appropriate", and that a sentence be included that EPA has concluded
       that there are no federal or state standards that are "relevant and appropriate" to the proposed
       amended soils remedy.


       EPA Response:  EPA considered the comment and agreed that the relevant and appropriate
       standards proposed required clarification. However, EPA believes specific landfill requirements
       are relevant and appropriate because landfilling and capping the contaminated Superfund soils in
       place (the remedy described in this Amended ROD) are sufficiently similar.  They are similar
       because in either case untreated contamination essentially remains below the surface. EPA must
       clearly assure the public it is adequately mitigating exposures to this contamination and it believes
       there are existing RCRA ARAR's that can provide such assurance. Having established there is
       just cause to list some ARAR's, EPA agrees that it should list only very specific ARAR's which
       describe specific performance as well as closure and post closure and care requirements.
       Consequently, to clarify which requirements are relevant and appropriate, EPA removed ARAR

-------
ROD Amendment No. 1
Appendix 0
Responsiveness Summary
Page 3

       citations that referenced RCRA requirements which were beyond the scope of this remedial action.
       However, there were specific requirements in those removed ARAR's which are relevent and
       appropriate.  Those requirements are groundwater monitoring as well as closure and post closure
       care actions. Therefore, in lieu of citing specific ARAR's EPA added specific groundwater
       monitoring and post closure requirements to the "Description of the New Alternative" text found
       in the Amended ROD.


    c.  Consistency with the 1988 ROD


       Comment: In the 1988 ROD, EPA concluded that those affected soils on the site that were
       covered by existing concrete did not pose an unacceptable risk to human health and the
       environment.  Thus, the selection of steel reinforced concrete to cap the currently uncapped areas
       of the site where affected soils contain constituents of concerns at levels in excess of the remedial
       goals, is consistent with the approach of the 1988 ROD.  Beazer believes that it may be
       appropriate to highlight this point further in the Proposed Amended ROD.


       EPA Response: EPA agrees the current ROD does not require excavating soil beneath existing
       structures and pavements at this time. However, the ROD states that if monitoring shows
       contaminants are leaching from beneath existing structures EPA may require additional remedial
       action (see ROD p.  32). Therefore EPA has not concluded that soils on the site covered by
       existing concrete will never threaten human health or the environment  Therefore in response to
       this comment EPA did not believe any changes to the proposed plan were required.


    d.  Remedial Approach


       Comment: Beazer would like to clarify that the aifected soil on site is not a hazardous waste
       unless it is actively managed. Moreover, much ot the soil would not qualify as a listed hazardous
       waste and does not exhibit a characteristic of a hazardous waste and, thus, would not be a
       hazardous waste, even if actively managed. Therefore, Beazer believes that it is more appropriate
       to refer to a "remedial approach" rather than a "hazardous waste i.^anagement approach" in the
       Proposed Amended ROD.


       EPA Response:  In  response to actively managing affected soil, a waste is not defined by how it is
       "actively managed."  In any event EPA agrees it is appropriate to modify references to "hazardous
       waste management approaches" to remedial approach.


2.   Specific Comments


    a.  Page 3, paragraph l.d.


       Comment: Beazer believes that, for purposes of the Proposed Amended ROD, it is more accurate
       to state:

ROD Amendment No. 1
Appendix D
Responsiveness Summary
Page 4

           In lieu of using the soil washing and soil flushing remedies originally selected in the
           1988 ROD, EPA proposes that the areas where surface contamination exceeds the
           1988 ROD established soil cleanup goals - 700 ppm total carcinogenic polynuclear
           aromatic hydrocarbons (cPAH)2 - be sealed with a reinforced concrete cover


       EPA Response: EPA agreed with Beazer's comment and made the suggested change.


    b.  Page 4, paragraph 1 .d, second subpangraph.


       Comment: Beazer recommends that this subparagraph be revised to state "Since capping
       contamination changes the remedial approach originally established in the ROD..."
       EPA Response: EPA agreed with Beazer's comment and made the suggested change.


    c.  Page 4, paragraph I.e. second subparagraph


       Comment: Beazer recommends that this subparagraph be revised to state:


           In 1993, during the remedial design phase BEI conducted a soil washing pilot study.
           The study's results conclusively demonstrated that forty percent (40%) of the soil
           volume could not be washed to meet the remedial goals contained in the ROD.
           Consequently, soil washing: (1) could not provide the level of protection required by
           the ROD; (2) failed to demonstrate short or long term effectiveness; (3) would not
           reduce toxicity, mobility or volume of COCs for forty percent of the volume; (4) is
           not implementable; and (5) is not cost-effective. Thereafter, BEI repeated its belief
           that any contamination beneath the surface does not pose a realistic health risk.
           Beazer requested that EPA reconsider the risk calculations, revising them to take into
           account reasonably foreseeable exposure pathways given the current and anticipated
           industrial site use.


       EPA Response: EPA reviewed Beazer's comment and, although it did not use the suggested
       revision, it agreed to rewrite the paragraph to clarify the point that the test did not provide
       sufficient information to conclude full scale soil washing operations would provide any benefit


    d.  Page 5, paragraph 2.b., lines 6-9.


       Comment:  Beazer recommends revising these lines to state:


           design effort BEI conducted a soil washing pilot study; however, the study
           conclusively demonstrated that forty (40%) percent of the soil volume could not be
           washed to meet the remedial goal.

       EPA Response: See response to comment 2(c), referencing Page 4, paragraph I.e. second
       subparagraph.


   e.  Page 5, paragraph 2.b., Line 21.


       Comment: Insert a new sentence and revise the last sentence:
           When preparing the 1988 ROD, EPA determined that existing concrete and structures
           provided sufficient protection against reasonably foreseeable exposure to soils affected
           by COCs at levels in excess of remedial goals. Similarly, based upon the revised EPA
           principal threat guidance, EPA believes BETs proposed concrete cover over
           previously uncapped areas affected by the same COCs at similar levels will provide
           reliable and sufficient containment and protection against reasonably foreseeable
           exposure pathways, and provide greater overall protection to human health and the
           environment than the 1988 ROD remedy


       EPA Response: See response to comment 2(c), Consistency with the 1988 ROD, above.


   f.  Page 6, Exposure Pathway, Table 1.


       Comment: We could not locate a reference to Table 1 in the text. In addition, we found Table I
       potentially to be confusing because it appears to include exposure pathways which are no longer
       viewed by EPA as "realistic".  Therefore, Beazer recommends that Table 1 be deleted.
       Alternatively, if it is not deleted, it should be labeled as "Four Exposure Pathway Assumptions
       Considered in Original RI/FS" and a corresponding textual reference thereto should be inserted.


       EPA Response: EPA included the reference to Table 1 in the second full paragraph of section 2(b),
       "Reasons for Amending the ROD." The purpose of Table 1 was to provide the potential pathways
       designated in the ROD.


   g.  Page 6, second paragraph, last sentence.


       Comment: Beazer recommends that the last sentence be revised to state:  "Therefore, this pathway
       does not present an unacceptable risk to human health and the environment


       EPA Response: EPA agreed with the suggested revision and included the revision in the
       amendment

       Comment: Beazer recommends that the last sentence be revised to state, "Furthermore, the deed
       restrictions imposed as a result of the administrative orders on consent with the property owners
       provide institutional controls to inhibit residential land use."
                                 i

       EPA Response:  EPA considered the comment but decided not to modify the proposed plan since
       the Administrative Order on Consent states residential land use is "inappropriate."


   i.   Page 7, first paragraph


       Comment:


          Beazer recommends that the first sentence be revised to state, "To summarize the reasons for
          amending the 1988 ROD, the soil washing pilot study conclusively demonstrated that soil
          washing was not cost-effective and would not achieve the remediation goals set forth in the
          1988 ROD."


          Beazer recommends that the last sentence be revised to state "EPA evaluated the land use and
          concluded that, given the current and most reasonably anticipated future land use, the concrete
          cap adequately would protect human health  and the environment by severing exposure
          pathways, just as the pre-existing concrete and structures were deemed to do in the  1988
          ROD."


       EPA Response:  See EPA Response to comment on 2(c), referencing Page 4, paragraph 1 .e,
       second subparagraph above.

    j.  Page 7, paragraph 3


       Comment:  As Beazer has previously discussed, it does not believe that the RCRA regulations
       listed in Table 3 are "relevant and appropriate" with respect to the proposed concrete cap.
       Therefore, Beazer requests that the last sentence be revised to state "EPA does not believe that
       there are any ARARs with respect to the proposed amended capping remedy." In addition, Table
       3 should be deleted.


       EPA Response: See EPA Response to comment "Applicable and Relevant and Appropriate
       Standards ("ARARs")"


    k.  Page 8, paragraph 4.a


       Comment:  Beazer believes that the list of potential exposure pathways may be confusing to the
       reader since the previous discussions indicated that: (1) the administrative order requirements
       imposed upon the property owners has eliminated the first category; (2) the second pathway
       category was determined not to pose an unacceptable risk; and (3) EPA has concluded that
       residential use is not a reasonably foreseeable future use of the property. Therefore, the only
       exposure pathway which remains is "inadvertent ingestion and direct contact with surface soils by
       on-site commercial occupants." Thus, it would be clearer to eliminate the first three exposure
       pathways included in the list or eliminate the list entirely.


       EPA Response: EPA considered the comment and agreed that the proposal could be clarified.
       The proposal was clarified by refering to only the most probable pathway identified in the
       "Summary of Rational for Changing the Remedy Selected In the ROD." See paragraph 5.a. in the
       Amende j ROD.


       Comment:  In addition, Beazer believes that it would be helpful to amend the sentence following
       the list of exposure pathways to state "Consequently, as long as the laud use remains similar to the
       present use, which is the only reasonably foreseeable use of the property for the many reasons
       discussed above, and the concrete cap...."


       EPA Response: EPA considered the comment but did not believe changing the proposed plan was
       warranted.


    1.  Page 8, paragraph 4.b


       Comment:  As discussed above, Beazer does not believe that the regulations listed on page 7 are
       ARARs. Thus, Beazer requests that this paragraph be revised to state:

-------

Pages

           The previous remedy, soil washing, will not meet the ARAR's. While there are no
           ARAR's with respect to the soils remedy set forth in the Proposed Amended ROD, the
           concrete cap will be designed so as to minimize the need for further maintenance.


       EPA Response: See EPA Response to comment l(b), "Applicable and Relevant and Appropriate
       Standards ("ARARs")."


    m.  Page 9, paragraph 4.d


       Comment: Beazer recommends that this section be revised to include an explanation that the pilot
       study did not conclusively demonstrate that the soil washing remedy would not adequately reduce
       toxicity, mobility or volume for forty percent (40%) of the affected soil.


       EPAResponse: EPA considered the response but concluded revising the proposed plan  was not
       necessary.


    n.  Page 9, paragraph 4.g, second subparagraph


          Comment:  Beazer requests that the first, second and third sentences be revised to state:


              As demonstrated by the soil washing pilot project, forty (40%) percent of the
              affected soils could not be remediated to the remedial goals through use of the soil
              washing remedy selected in the 1988 ROD. This would increase the financial risk
              for bidders because the final volume of soil which could be treated and the
              volume whid-  vould have to be disposed is uncertain. Such uncertainty will
              increase the bid cost of the soil washing remedy. Elimination of the uncertainty
              improves cost control.


          EPAResponse: EPA considered the response  but concluded revising the proposed plan was
          not necessary.

      RE: Proposed ROD Amendment
           Sooth Cavalcade CERCLA Site
           Houston Tx

      Dear Ms. Balandras

      Palletized Trucking, Inc. is writing to provide the United States Environmental Protection
      Agency with comments on the proposed Record of Decision (ROD) Amendment which woul(f
      allow the use of concrete capping as a soil remedy at the South Cavalcade Superrand site.

      As you are aware, we are a property-owner at this site, and have even signed a Consent Order
      with the USEPA regarding this site.  We are very pleased to see the USEPA .oially move
      forward with allowing Beazer to place a concrete cap as the final remedy for impacted soils a!
      this site.  It has been nearly two years since Beazer started full scale remediation activities',
      which required n« tnvarafc a tignifiranf portion of am trailer parting area  Vacating that area
      for such a long period, of time has hindered our operational efficiency and costs us a significant
      sum of money. The delay has also prevented us from proceeding with our tire shop
      improvement project, which would be located in an area of the proposed concrete cafk.

      By approving the proposed ROD Amendment and allowing Beazer to proceed with the
          rete cap installation, the USEPA will be taking a positive step toward returning this
      property to its full business potential.  Additionally, the new concrete cap will provide us with
      an improved working surface versus the crushed concrete surface formerly used along the
      eastern side of our property.  We have agreed with Beazer to accept responsibility for the
      maintenance of this new concrete surface, which is consistent with our own Consent Order
      requirements to properly maintain the existing concrete areas on our property.

      Dear Ms. Balandriac

      NW NationsWsy Transport Service, Inc. is writing in support of the United States Environmental
      Protection Agency's proposed Record of Decision (ROD) Amendment to allow concrete capping
      as the soil remedy for the South Cavalcade Supcrfund sit*

      NadonsWay recently purchased the northern portion of tLLi site.  Since that purchase we hav*
      been exploring several facility expansion alternatives.   Several of these expansion alternatives
      would "K^wte aAfitjftnai tarmac areas overlying the "iy^r*<^f soil area on our property.  The
      removal of this soil from our property as proposed in Beazer*s January. 1996 Conceptual Design
      would provide the dearest path for any of our potential facility expansion projects, and  allow us
      to completely irtifo* the property's trucking terminal potential  ft is our understanding that the
      USEPA's approval of the proposed ROD Amendment will iDow this soil removal to happen in a
      timely manner,  therefore we support the proposed ROD Amendment
