I. Introduction
II. NPL Deletion Criteria
III. Deletion Procedures
IV. Basis for Intended Partial Site Deletion

I. Introduction

    EPA Region 7 announces its intent to delete the Callahan property, 
OU3 of the Ellisville Superfund Site, from the National Priorities List 
(NPL) and requests public comment on this proposed action. The NPL 
constitutes appendix B of 40 CFR 300, which is the National Oil and 
Hazardous Substances Pollution Contingency Plan (NCP), which EPA 
promulgated pursuant to section 105 of the Comprehensive Environmental 
Response, Compensation and Liability Act (CERCLA) of 1980, as amended. 
EPA maintains the NPL as those sites that appear to present a 
significant risk to public health, welfare, or the environment. Sites 
on the NPL may be the subject of remedial actions financed by the 
Hazardous Substance Superfund (Fund). This partial deletion of the 
Callahan property, OU3, is proposed in accordance with 40 CFR 
300.425(e) and is consistent with the Notice of Policy Change: Partial 
Deletion of Sites Listed on the National Priorities List. 60 FR 55466 
(November 1, 1995). As described in 300.425(e)(3) of the NCP, a portion 
of a site deleted from the NPL remains eligible for Fund-financed 
remedial action if future conditions warrant such actions.
    EPA will accept comments on the proposal to partially delete this 
site for thirty (30) days after publication of this document in the 
Federal Register.
    Section II of this document explains the criteria for deleting 
sites from the NPL. Section III discusses procedures that EPA is using 
for this action. Section IV discusses the Callahan property, OU3 of the 
Ellisville Superfund Site and demonstrates how it meets the deletion 
criteria.

II. NPL Deletion Criteria

    The NCP establishes the criteria that EPA uses to delete sites from 
the NPL. In accordance with 40 CFR 300.425(e), sites may be deleted 
from the NPL where no further response is appropriate. In making such a 
determination pursuant to 40 CFR 300.425(e), EPA will consider, in 
consultation with the State, whether any of the following criteria have 
been met:
    i. Responsible parties or other persons have implemented all 
appropriate response actions required;
    ii. all appropriate Fund-financed response under CERCLA has been 
implemented, and no further response action by responsible parties is 
appropriate; or
    iii. the remedial investigation has shown that the release poses no 
significant threat to public health or the environment and, therefore, 
the taking of remedial measures is not appropriate.

III. Deletion Procedures

    The following procedures apply to deletion of Callahan property, 
OU3 of the Ellisville Site:
    (1) EPA consulted with the State before developing this Notice of 
Intent for Partial Deletion.
    (2) EPA has provided the state 30 working days for review of this 
notice prior to publication of it today.
    (3) In accordance with the criteria discussed above, EPA in 
consultation with the state, has determined that no further response is 
appropriate.
    (4) The State of Missouri, through the Missouri Department of 
Natural Resources, has concurred with the deletion of the Callahan 
Subsite property, OU3 of the Ellisville Superfund Site, from the NPL.
    (5) Concurrently, with the publication of this Notice of Intent for 
Partial Deletion in the Federal Register, a notice is being published 
in a major local newspaper, Eureka-Wildwood Patch. The newspaper 
announces the 30-day public comment period concerning the Notice of 
Intent for Partial Deletion of the Site from the NPL.
    (6) The EPA placed copies of documents supporting the proposed 
partial deletion in the deletion docket and made these items available 
for public inspection and copying at the Site information repositories 
identified above.
    If comments are received within the 30-day comment period on this 
document, EPA will evaluate and respond accordingly to the comments 
before making a final decision to delete the Callahan property, OU3. If 
necessary, EPA will prepare a Responsiveness Summary to address any 
significant public comments received. After the public comment period, 
if EPA determines, in consultation with the State, it is still 
appropriate to delete the Callahan property, OU3 of the Ellisville 
Superfund Site, the Regional Administrator will publish a final Notice 
of Partial Deletion in the Federal Register. Public notices, public 
submissions and copies of the Responsiveness Summary, if prepared, will 
be made available to interested parties and included in the site 
information repositories listed above.
    Deletion of a portion of a site from the NPL does not itself 
create, alter, or revoke any individual's rights or obligations. 
Deletion of a portion of a site from the NPL does not in any way alter 
EPA's right to take enforcement actions, as appropriate. The NPL is 
designed primarily for informational purposes and to assist EPA 
management. Section 300.425(e)(3) of the NCP states that the deletion 
of a site from the NPL does not preclude eligibility for future 
response actions, should future conditions warrant such actions.

IV. Basis for Partial Site Deletion

    The following information provides EPA's rationale for deleting the 
Callahan

[[Page 14815]]

property, OU3 of the Ellisville Superfund Site from the NPL:

Site Background and History

Site Location
    The Ellisville Superfund Site (Site) (EPA ID MOD980633010) is 
located in St. Louis County, approximately 20 miles from downtown St. 
Louis, Missouri. The Site is comprised of three non-contiguous operable 
units the Bliss property, OU2 (11.6 acres), the Callahan property, OU3 
(8 acres), and the Rosalie property, OU1 (85 acres). The population of 
St. Louis County is 998,954 people, according to the 2010 census. The 
counties that surround St. Louis County are Saint Charles, Franklin, 
and Jefferson Counties. The area immediately around the Site is 
comprised of single-family detached residential dwellings. The Site is 
located in the watershed of Caulks Creek, a tributary of Bonhomme Creek 
that enters the Missouri river. The geology of the Site is underlain by 
unconsolidated deposits that rest on the Mississippian-aged Osagean 
Series limestone bedrock with solution-enlarged joints. Below the 
Mississippian-aged Osagean Series limestone lies the Maquoketa 
Formation that provides a relatively impermeable shale aquitard.
National Priorities List Designation
    The Site was proposed for inclusion on the NPL on December 30, 1982 
(47 FR 58476). It was listed for final inclusion on the NPL September 
8, 1983 (48 FR 40658-40673).
Operable Units (OUs) Descriptions Not Proposed for Deletion
    The Rosalie property, OU1 is an 85-acre tract of land in which four 
acres were contaminated. The Rosalie property, OU1 was discovered in 
1980 when a sewer worker encountered buried drums during an excavation. 
Drummed liquid and solid wastes were disposed of in and near Caulks 
Creeks. The Rosalie property OU1 cleanup remedy included the excavation 
of drums from four locations and the removal of contaminated soil from 
two of these locations. The drums and contaminated soils were disposed 
of at an EPA approved hazardous waste facility. Over 200 drums 
including one and five gallon buckets of chemical wastes were removed 
from the property. Of the 200 drums, only 45 contained suspected 
hazardous waste materials. Confirmation soil samples were collected to 
verify the effectiveness of the cleanup and the excavated areas were 
backfilled with clean soil and reseeded.
    The Bliss property, OU2 is located at 149 Strecker Road in the city 
of Wildwood, Missouri. Features on the Bliss property include a 
residential house, one mobile home, an enclosed horse arena with 
associated buildings and stables. The MDNR began investigating the site 
in 1980, when an informant reported illegal dumping of hazardous waste 
at the property. Russell Bliss owned and operated the Bliss Waste Oil 
Company during the 1960s and 1970s at the site. The business engaged in 
the transportation and disposal of waste oil products, industrial 
wastes, and chemical wastes. These wastes were disposed of in pits, 
buried in drums, and liquid wastes were dumped on the surface of the 
ground. Cleanup activities began February 6, 1996, and the permit for 
the incinerator at Times Beach was issued March 15, 1996, for the 
treatment of dioxin contaminated waste. Dioxin contaminated soil was 
removed according to the approved health-based action levels of 1 ppb 
at the surface and 10 ppb at a depth of 12 inches, except fill areas 
where the action level was 1 ppb at all depths. In the creek, the 
dioxin action levels were 1 ppb to 2 feet, depths greater than 2 feet 
were cleaned up to 10 ppb. Air monitoring and temporary containment 
structures were erected to ensure and prevent airborne contaminants 
from migrating off-site. At the end of the cleanup on the Bliss 
property OU2, 480 drums were removed and 252 soil confirmation samples 
were collected. A total of 24,478 tons of dioxin contaminated soil were 
excavated, removed, and incinerated at the Times Beach incinerator. 
Another 581 tons of non-dioxin contaminated soil were also excavated 
and removed to either LWD, Inc. landfill or Rollins Environmental 
Services landfill both Resource Conservation and Recovery Act (RCRA) 
permitted landfills. Groundwater investigations at the Bliss property, 
OU2 are ongoing.
Operational Unit Description Proposed for Deletion and Historic 
Activities
    The Callahan property, OU3, is located at 210 Strecker Road in the 
city of Wildwood, Missouri. Features on the Callahan property include a 
small pond and barn. The small pond receives drainage from the northern 
portion of the parcel and is located above the former drum burial area 
(fill area). The terrain at the Callahan property slopes downward to 
the south from Strecker Road forming two drainage ways (below the fill 
area) that intersect at an intermittent Caulks Creek tributary near the 
southernmost property boundary.
    In August 1980, the MDNR received an eyewitness report that drums 
were being buried near a barn on the Callahan property. A follow up 
investigation revealed a disposal area of approximately 150 feet x 150 
feet. During additional investigations, several drums were unearthed 
and sampled. Sample results determined that the drums contained paint-
related wastes and solvents. The MDNR subsequently requested assistance 
from the EPA to address the buried drums, and a removal action (RA) was 
immediately initiated. Under section 104 of CERCLA, the RA took place 
during December 1981 to February 1982, when 1,205 drums were removed 
from the disposal area. Of these 1,205 drums, 613 contained hazardous 
waste, which were over packed and staged in two areas on the site for 
off-site disposal. Approximately 500 cubic yards of excavated soil was 
returned to the excavated drum burial area as backfill (Tetra Tech EM 
Inc. 2005).

Remedial Investigation and Feasibility Study (RI/FS)

    The Remedial Investigation field activities on the Callahan 
property, OU3 occurred in 1983 in which seven soil samples (ELL-21--
ELL-25, ELL-31, ELL-32) and two surface water samples (ELL-26 and ELL-
27) were collected. Soil results exceed the EPAs current residential 
RSLs at ELL-31 and ELL-32 for methylene chloride and oxirane. Surface 
water results were non-detect for contaminants of concern.
    The Feasibility Study identified remedial action objectives that 
were to control the erosion and stabilize the fill area where drums had 
been excavated. In addition, the plastic cover, blocks, barbed-wire 
fence, the drum storage areas, and gravel from the previous response 
action were also to be removed and properly disposed.

Selected Remedy

    On July 10, 1985, the Record of Decision for the Ellisville site 
was signed. The remedy selected for the Callahan property, OU3 was to 
control erosion and slippage of the fill area, remove the plastic 
cover, blocks, barbed-wire fence, drum storage areas, and gravel and 
properly dispose of them. The shallow groundwater beneath the Callahan 
property is a non-potable water bearing zone due to insufficient yield. 
There is no reasonably anticipated use of site groundwater and no 
available groundwater exposure route for receptors. The ROD did thus 
not require any groundwater response.

[[Page 14816]]

    In December 1999, James Properties hired Brucker Engineering to 
conduct a Phase II Environmental Assessment on the Callahan property. 
During that investigation, five composite samples were collected and 
analyzed for dioxin, polychlorinated biphenyls (PCBs), pesticides, and 
metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, 
and silver). All sample results were non-detect for contaminants of 
concern. A magnetic survey was also conducted during the investigation 
that showed no evidence of buried metal drums. A Site Removal 
Evaluation was conducted by the MDNR on January 31, 2005, to determine 
if any residual soil contamination remained at the Callahan property at 
concentrations that would warrant further response. A total of 29 soil 
and five sediment samples were collected during January 31, 2005 
through February 2, 2005. All samples were analyzed for base neutral/
acid extractables, pesticides/herbicides, PCBs, metals (arsenic, 
barium, cadmium, chromium, lead, mercury, selenium, and silver), and 
dioxin. Results exceeded the EPA's current residential Regional 
Screening Levels (RSL's) for soil at monitoring location EU-6 for 
ethylbenzene, tetrachloroethene, and 1,2,4-trimethylbenzene.
    The EPA conducted an expanded site review in September 2011 on the 
Callahan property. A total of 34 soil samples were collected. Dioxin, 
metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, 
and silver), PCBs, SVOCs, and VOCs were analyzed on one or more 
samples. Results exceeded the EPA's current Residential RSL's for soil 
at soil borings SB-25 (lead), SB-26 (bis-(2-ethylhexyl)phthalate), SB-
27 (lead), SB-44 (benzo(a)anthracene, benzo(b)fluoranthene, 
ethylbenzene), and ditch grab #1 (arochlor 1248). Shallow groundwater 
was also investigated with no detections of contaminants of concern 
being identified.

Time Critical Removal Action (RA)

    Based on the 2011 expanded site review, on September 13, 2012, the 
EPA issued an Action Memorandum authorizing funding for a Time Critical 
Removal Action at the Callahan property, OU3. Specific actions were 
undertaken at the site to eliminate the threats to human health and the 
environment from contamination found remaining in place. These actions 
included the excavation, transportation, and disposal of VOCs, 
polycyclic aromatic hydrocarbons, and lead-contaminated waste/soils 
from the Site to a permitted disposal facility and restoration of the 
Site. The factors from the NCP that justified a removal action at the 
Site detailed in the Action memorandum are outlined below.
    1. 300.415(b)(2)(i)--Actual or potential exposure to nearby human 
populations, animals or the food chain from hazardous substances, or 
pollutants, or contaminants.
     The Site is located within 50 feet of a residential home 
that is located in a residential neighborhood. If the soils were to be 
brought to the surface, perhaps during a future housing development, 
the chances of this waste being spread across an area could expose 
current and future residents to these contaminants.
    2. 300.415(b)(2)(ii)--Actual or potential contamination of drinking 
water supplies or sensitive ecosystems;
     The EPA placed a monitoring well in the area where the 
buried waste was located. Groundwater results from the monitoring well 
were non-detect for contaminants of concern. However, due to the karst 
topography, at the site, one monitoring well would not be sufficient to 
identify if contamination had or had not migrated to the groundwater. 
If the contamination had not migrated to the groundwater, given time, 
contaminants could have leached and migrated to groundwater. Given that 
the bedrock is karst, it was in the EPA's best interest to prevent 
contamination from entering the groundwater system.
    3. 300.415(b)(2)(v)--Weather conditions that may cause hazardous 
substances or pollutants or contaminants to migrate or be released;
     Contaminated soils at the Callahan property had the 
potential to erode/leach from its current buried location. The 
contaminated soil was buried between a pond and the top of a drainage 
way that emptied into Caulks Creek. Caulks Creek is a major creek that 
runs through multiple sub-divisions in the area. It was foreseeable, 
since the waste was buried at shallow depths, that heavy rains could 
cause the hillside to become unstable releasing the buried waste into 
the drainage way.
    4. 300.415(b)(2)(vii)--The lack of other appropriate Federal or 
state response mechanisms to respond to the release.
     No other Federal or state authorities existed that would 
be able to provide response actions at the Site.
    The RA was conducted during November 27, 2012, through December 6, 
2012. Contaminated soil was removed by an excavator and then placed 
directly into dump trucks for disposal at the Milam Landfill in East 
St. Louis, Illinois. During the removal action, a PID photoionization 
detector (PID) was used for real-time air monitoring to ensure that 
VOCs generated during the excavation activities were below acceptable 
criteria levels within the immediate area surrounding the excavation 
pit, as well as along the site perimeter adjacent to residential 
properties bordering the site. A personal air sampler was also used to 
measure lead concentrations in the breathing zone of workers during 
excavation activities. Elevated levels of lead in the breathing zone 
were not observed during the removal action.
    Excavation activities proceeded first by visual observation, once 
visual indicators were no longer observed, the soil was then screened 
using a PID for VOCs and an x-ray fluorescence (XRF) spectrometer for 
metals (lead in particular). At the completion of the excavation, seven 
confirmation soil samples and one stockpile confirmation sample (CA-SW-
01, CA-EW-01, CA-EW-02, CA-WW-01, CA-WW-02, CA-NW-01, CA-NW-02, and CA-
OVRSTK-01) were collected for laboratory analysis. All confirmation 
samples were analyzed for VOCs, SVOCs, metals (arsenic, barium, 
cadmium, chromium, lead, mercury, selenium, and silver), and PCBs. 
Analytical results for all confirmation samples were compared to the 
current EPA RSLs. All results were below RSLs except those for arsenic. 
However, arsenic results were below the average background 
concentration of 10.561 ppm for St. Louis County soils (USGS 2012), and 
no additional cleanup was required.
    The excavation of contaminated soil on the Callahan property, OU3 
was completed on December 6, 2012. A total of 2,056 tons of 
contaminated soil and debris, including drum fragments and metal 
pieces, were excavated and transported to the Milam Landfill for proper 
disposal as non-hazardous ``special waste.'' The landfill accepted the 
waste based on disposal characterization sampling results (from 
November 2012), which had indicated that contaminated soil at the site 
did not contain hazardous constituents above acceptable levels or leach 
constituents above corresponding regulatory toxicity characteristic 
leaching procedure limits. The final excavated area was approximately 
21 feet long on the south wall, 75 feet on the east wall, 70 feet on 
the north wall, and 82 feet on the west wall. The depth of the 
excavated area ranged from 5 to 15 feet.
    Following completion of the soil excavation, the excavation was 
backfilled and the site restored. One grab sample of off-site backfill 
material

[[Page 14817]]

(CAL-BF-1) and one grab sample of off-site topsoil (CA-TPSL-01) were 
collected to confirm that the backfill material and topsoil did not 
contain contaminants above levels of concern. The samples were analyzed 
for VOCs, SVOCs, and metals (arsenic, barium, cadmium, chromium, lead, 
mercury, selenium, and silver). Laboratory results demonstrated that 
the backfill and topsoil samples did not contain any contaminants above 
current EPA RSLs.
    Following completion of backfilling, the site was restored in 
accordance with verbal agreements between the EPA and the property 
owner. The excavated area was completed with a swale that included rip-
rap to serve as a drainage route, while the remaining portion of the 
site property was restored by hydro-seeding. The swale was 
approximately 8 feet wide by 150 feet long, and the rock used for rip-
rap was 6 to 8 inch Gabien stone. Following completion of site 
restoration activities, the removal action was considered complete.

Cleanup Levels

    The cleanup levels for the Callahan RA were the current EPAs RSLs. 
The process used during the RA was to excavate all visibly stained and/
or odorous soils then field screen the excavation walls using an XRF 
and a PID. Once completed, confirmation soil samples were collected and 
submitted for analysis to ensure that all contaminants above RSLs had 
been excavated and removed from the site. Once the confirmation 
analytical results confirmed that levels were below RSLs, the excavated 
area was backfilled with clean material.

Community Involvement

    The EPA has worked extensively with the Wildwood community through 
a variety of communication vehicles including but not limited to local 
speaking engagements, city council meetings, conducting public 
meetings, coverage on radio, television, and in local and national 
newspapers. The EPA also prepared letters and fact sheets that were 
distributed to mailing list recipients as well as hand-distributed to 
residences including information on the EPA Web site.
    The EPA has been performing outreach to Wildwood citizens, elected 
officials, the media, and others since becoming involved in the project 
in 1980 in an effort to convey information about the hazards and 
activities of the Site. The EPA has participated in numerous formal and 
informal meetings to explain the EPA's role and commitment in Wildwood 
to convey information about the Superfund process and to provide 
general information about the site and its contamination.

Determination That the Criteria for Deletion Have Been Met

    In accordance with 40 CFR 300.425(e), Region 7 of the EPA finds 
that the Callahan property, OU3 of the Ellisville Superfund site (the 
subject of this deletion) meets the substantive criteria for partial 
NPL deletions. Activities at the Callahan property were completed 
consistent with the Action Memo and the Statement of Work, and the EPA 
policies and procedures. The EPA analytical methods were used for all 
investigations, including confirmation sampling and various levels of 
data validation as appropriate. The QA/QC program was rigorous and in 
conformance with the EPA standards. The EPA has determined that all 
analytical results were accurate to the degree necessary to assure 
satisfactory execution of the investigation and removal activities. All 
confirmation analytical results for soil samples were compared to the 
current EPA RSLs. All results were below the EPA RSLs except those for 
arsenic; however, all arsenic results were below the average 
concentration of 10.561 ppm for St. Louis County soils (USGS 2012).
