IV. Basis for Intended Partial Site Deletion

I. Introduction

The U.S. Environmental Protection

Agency (EPA) Region 6 announces its

intent to delete Moton Elementary

School, including Mugrauer Playground

(Operable Unit 4) and Groundwater

(Operable Unit 5), two portions of the

Agriculture Street Landfill Superfund

Site from the National Priorities List

(NPL), Appendix B of the National Oil

and Hazardous Substances Pollution

Contingency Plan (NCP), Code of

Federal Regulations, Title 40 (40 CFR),

Part 300, and requests comments on the

proposed deletion. OU Nos. 1, 2, and 3

(undeveloped property, residential area,

and Shirley Jefferson Community

Center) are not the subject of this partial

deletion.

The EPA identifies sites that appear to

present a significant risk to public

health, welfare, or the environment and

maintains the NPL as the list of those

sites. As described in § 300.425(e)(3) of

the NCP, sites or portions of sites

deleted from the NPL remain eligible for

remedial actions in the unlikely event

that site conditions warrant such action.

The EPA will accept comments

concerning its intent to delete OU Nos.

4 and 5 for thirty (30) days after

publication of this notice. The EPA has

also published a notice of the

availability of this Notice Of Intent for

Partial Deletion (NOID) in a major

newspaper of general circulation at or

near the site.

Section II of this notice explains the

criteria for deleting sites from the NPL.

Section III discusses procedures that

EPA is using for this action. Section IV

discusses the Agriculture Street Landfill

Superfund site and demonstrates how

Operable Units 4 and 5 meet the

deletion criteria.

II. NPL Deletion Criteria

Section 300.425(e) of the NCP

provides that releases may be deleted

from, or recategorized on the NPL where

no further response is appropriate. In

making a determination to delete a

release from the NPL, EPA shall

consider, in consultation with the State,

whether any of the following criteria

have been met:

i. Responsible parties or other parties

have implemented all appropriate

response actions required;

ii. All appropriate Fund-financed

response under CERCLA has been

implemented, and no further 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, taking of

remedial measures is not appropriate.

Even if a site is deleted from the NPL,

where hazardous substances, pollutants,

or contaminants remain at the site above

levels that allow for unlimited use and

unrestricted exposure, CERCLA Section

121(c), 42 U.S.C. 9621(c) requires that a

subsequent review of the site be

conducted at least every five years after

the initiation of the remedial action at

the site to ensure that the action remains

protective of public health and the

environment. If new information

becomes available which indicates a

need for further action, EPA may initiate

remedial actions. Whenever there is a

significant release from a site deleted

from the NPL, the site may be restored

to the NPL without application of the

Hazard Ranking System.

III. Deletion Procedures

The following procedures were used

for the proposed deletion of the site:

(1) EPA Region 6 issued a Record of

Decision on September 2, 1997 which

documented that no further remedial

action is necessary to ensure protection

of human health and the environment

for Agriculture Street Landfill’s

Operable Unit 4 and Operable Unit 5;

(2) LDEQ, on behalf of the State of

Louisiana, concurred by letter dated

August 28, 1997, with EPA’s decision

that no action was necessary for

Operable Units 4 and 5 and that

deletion from the NPL was appropriate;

(3) A notice has been published in the

local newspaper and has been

distributed to appropriate federal, state,

and local officials and other interested

parties announcing the availability of

the Notice of Intent for Partial Deletion

and the commencement of a 30-day

public comment period; and,

(4) EPA placed copies of documents

supporting the proposed deletion in the

site information repositories identified

above.

Deletion of a site from the NPL does

not itself create, alter, or revoke any

individual’s rights or obligations. The

NPL is designed primarily for

informational purposes and to assist

Agency management. As mentioned in

Section II of this notice, 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.

This Federal Register notice, and a

concurrent notice in a newspaper of

record, announce the initiation of a

thirty (30) day public comment period

and the availability of the Notice of

Intent for Partial Deletion. The public is

asked to comment on EPA’s proposal to

delete OU Nos. 4 and 5 from the NPL.

All critical documents needed to

5846 Federal Register / Vol. 65, No. 25 / Monday, February 7, 2000 / Proposed Rules

evaluate EPA’s decision are included in

the Deletion Docket and are available for

review at the information repositories.

Upon completion of the thirty (30)

day public comment period, EPA will

evaluate all comments received before

issuing the final decision on the partial

deletion. The EPA will prepare a

Responsiveness Summary for comments

received during the public comment

period and will address concerns

presented in the comments. The

Responsiveness Summary will be made

available to the public at the

information repositories listed

previously, and members of the public

are encouraged to review them. If, after

review of all public comments, EPA

determines that the partial deletion from

the NPL is appropriate, EPA will

publish a final notice of partial deletion

in the Federal Register. Deletion of OU

Nos. 4 and 5 does not actually occur

until the final Notice of Partial Deletion

is published in the Federal Register.

IV. Basis for Intended Partial Site

Deletion

The following information provides

the Agency’s rationale for the proposal

to delete OU Nos. 4 and 5 from the NPL

and EPA’s finding that the criteria in 40

CFR 300.425(e) are satisfied.

A. Site Location

The Agriculture Street Landfill

Superfund Site (site) is approximately

95 acres and is located in the eastern

section of the city of New Orleans. The

site is bound on the north by Higgins

Boulevard, and on the south and west

by the Southern Railroad rights-of-way.

The eastern site boundary extends from

the cul-de-sac at the southern end of

Clouet Street, near the railroad tracks, to

Higgins Boulevard between Press and

Montegut streets. Approximately 48

acres are undeveloped property. The

other 47 acres are developed with

multiple- and single-family residences,

commercial properties, a community

center, and a school.

To effectively investigate and develop

alternatives for the remediation of the

site, EPA divided the site into five

operable units (OUs):

• OU1—The undeveloped (currently

fenced-in) property;

• OU2—The residential development

which consists of the Gordon Plaza

Apartments, single family dwellings

in Gordon Plaza subdivision, and

the Press Park town homes;

• OU3—Shirley Jefferson Community

Center (formerly known as Press

Park Community Center);

• OU4—Moton Elementary School

which includes Mugrauer

Playground; and,

• OU5—Groundwater.

Operable Unit 4 is located in the

southeast corner of the site. Coordinates

for its four corners, beginning in the

northwest are 29°59′ 18.76′′ north

latitude, 90°02′ 20.26′′ west longitude;

29°59′ 17.52′′ north latitude, 90°02′

20.52′′ west longitude; 29°59′ 11.12′′

north latitude, 90°02′ 27.67′′ west

longitude; and 29°59′ 09.63′′ north

latitude, 90°02′ 21.76′′ west longitude.

Operable Unit 5 is designated as the

groundwater beneath the site, within

which no identified plume of

contamination has been specified.

B. Site History

The Agriculture Street Landfill was a

municipal waste landfill operated by the

City of New Orleans. Operations at the

site began in approximately 1909 and

continued until the landfill was closed

in the late 1950’s. The landfill was

reopened for approximately one year in

1965 for use as an open burning and

disposal area for debris left in the wake

of Hurricane Betsy. Records indicate

that during its operation the landfill

received municipal waste, ash from the

city’s incineration of municipal waste,

and debris and ash from open burning.

There is no evidence that industrial or

chemical wastes were ever transported

to, or disposed of at, the site.

From the 1970’s through the late

1980’s, approximately 47 acres of the

site were developed for private and

public uses that included: private

single-family homes, multiple-family

private and public housing units,

Shirley Jefferson Community Center, a

recreation center, retail businesses, the

Moton Elementary School, and an

electrical substation. The remaining 48

acres of the former landfill are currently

undeveloped and covered with

vegetation. Previous investigations on

the undeveloped property have

indicated the presence of hazardous

substances, pollutants, or contaminants

at concentrations above background

and/or regulatory levels.

In 1986, EPA Region 6 conducted a

Site Inspection and prepared a Hazard

Ranking System (HRS) documentation

record package utilizing the 1982 HRS

model. The site score was not sufficient

for the site to be considered for proposal

and inclusion on the NPL. Pursuant to

the requirements of Superfund

Amendment and Reauthorization Act of

1986 (SARA), which amended the

original Superfund legislation, EPA

published a revised HRS model on

December 14, 1990. At the request of

area community leaders, EPA initiated,

in September 1993, an Expanded Site

Inspection (ESI) to support the

preparation of an updated HRS

documentation record package that

would evaluate the site’s risks using the

revised HRS model. Subsequently, on

August 23, 1994, the site was proposed

for inclusion on the NPL as part of NPL

update No. 17, and on December 16,

1994, EPA placed the site on the NPL.

Prior to 1994, access to OU1, the

undeveloped portion of the former

landfill, was unrestricted, allowing

unauthorized waste disposal and

exposure to contaminants of potential

concern such as lead, arsenic and

carcinogenic polynuclear aromatic

hydrocarbons (cPAHs) found in the

surface and subsurface soils. In a timecritical removal action, initiated in

March 1994, EPA installed an 8-foothigh, chain-link fence topped with

barbed wire around the entire

undeveloped portion of the former

landfill.

Concurrent with the time-critical

removal action, EPA performed a

Remedial Removal Integrated

Investigation (RRII) of the entire site.

RRII fieldwork was conducted from

April 4 through June 20, 1994. Samples

of surface and subsurface soil, sediment,

surface water, groundwater, air, dust,

tap water, garden produce, and paint

chips collected during the field

investigation were submitted to

specialized laboratories for analysis.

Aerial photographs, geophysical

investigations and computer modeling

were used to supplement the analytical

data in defining site boundaries and

evaluating migration pathways. These

data were also used to prepare the

Human Health Risk Assessment and the

Ecological Risk Assessment.

Based on information presented in the

RRII report, EPA conducted a second

time-critical removal action at the site in

February 1995, and performed

confirmational air and groundwater

sampling. Through this sampling event,

EPA was able to obtain a second round

of analyses of the groundwater, to

clarify earlier identified ambient air

contaminants, and to verify composition

and magnitude of indoor air

contaminants. In 1995, EPA prepared an

Engineering Evaluation and Cost

Analysis examining response action

alternatives for Operable Units 1–3.

EPA Region 6 issued a Record of

Decision selecting the no action

alternative for Operable Units 4 and 5

on September 2, 1997. On the same day,

EPA signed an Action Memorandum

selecting non-time-critical removal

actions for Operable Units 1, 2, and 3.

C. Characterization of Risk

No further action will be taken by

EPA on Moton School, including the

Mugrauer Playground (OU4) and

Federal Register / Vol. 65, No. 25 / Monday, February 7, 2000 / Proposed Rules 5847

Groundwater (OU5). This decision is

based on the risk assessment that

evaluated Moton School (OU4) and

Groundwater (OU5), which concluded

that no unacceptable risk exists that is

attributable to site related contaminants.

The baseline Human Health Risk

Assessment, conducted as part of the

Remedial Removal Integrated

Investigation for this site, evaluated

potential adverse health effects

associated with site-related

contaminants in the absence of remedial

action. As part of the baseline Risk

Assessment, an extensive evaluation of

exposures to lead was performed, using

EPA’s Integrated Exposure Uptake

Biokinetic (IEUBK) model. For

contaminants other than lead, the

likelihood of adverse public health

impacts associated with long-term

exposure to site-related contaminants

was determined by (a) estimating

potential excess lifetime cancer risks for

carcinogens and (b) by computing

hazard indices (HIs) for noncarcinogens. Federal laws, regulations,

and guidance define a range of

acceptable cancer risks of 1 × 10¥4 (one

in ten thousand) to 1 × 10¥6 (one in one

million), and a Hazard Index of unity (1)

for non-cancer risks.

For Moton School (OU4), the total

excess lifetime cancer risk posed to

children attending the school was

estimated 2 × 10¥5 (or two in one

hundred thousand), which is within the

acceptable risk range specified by

federal law, regulations, and guidance.

Most of this estimated risk was

attributable to inhalation of non-siterelated benzene and chloroform from

indoor and outdoor air. In addition,

none of the HIs exceeded EPA’s

regulatory benchmark of unity.

Given the findings of the Risk

Assessment, no further action for this

operable unit is warranted. Deletion

from the NPL should clear the way for

beneficial utilization of the property of

the City of New Orleans or the New

Orleans School Board.

For the Groundwater Operable Unit,

(OU5), information supplied to EPA by

the Louisiana Department of

Environmental Quality indicates that

the shallow aquifer beneath the site is

not suitable for human consumption, is

not used for any beneficial purpose, and

is not considered a potential future

source of drinking water. Residents at

the site area are connected to the

municipal water supply for domestic

water requirements. There are no on-site

drinking water wells. Site groundwater

presents no other exposure pathway.

Therefore, no further action for this

operable unit is warranted.

Because these no-action remedies will

result in hazardous substances

remaining on-site, a review will be

conducted every five years after

commencement of remedial action in

accordance with CERCLA Section

121(c), 42 U.S.C. 9621(c). Should future

reviews indicate that the site poses an

unacceptable risk to human health or

the environment, then EPA may initiate

response actions under the authority of

CERCLA and in accordance with the

NCP.

D. Community Involvement

Public participation activities have

been satisfied as required in CERCLA

Section 113(k), 42 U.S.C. 9613(k), and

Section 117, 42 U.S.C. 9617. Documents

in the deletion docket which EPA relied

on for recommendation of the Partial

deletion from the NPL are available to

the public in the information

repositories.

E. Proposed Action

The EPA, with concurrence of the

State of Louisiana (LDEQ), has

determined that Operable Unit 4 (Moton

Elementary School, including Mugrauer

Playground) and Operable Unit 5

(Groundwater) pose no significant threat

to public health or the environment;

therefore, no remedial measures are

appropriate. In accordance with EPA

policy on partial deletion of sites listed

on the National Priorities List, EPA

proposes to delete OU4 and OU5 from

the NPL.

SUPPLEMENTARY INFORMATION:

I. Background

On May 20, 1999, the National

Highway Traffic Safety Administration

(NHTSA) published a notice of intent to

establish an advisory committee

(Committee) for a negotiated rulemaking

to develop recommendations for

regulations governing the certification of

vehicles built in two or more stages. The

notice requested comment on

membership, the interests affected by

the rulemaking, the issues that the

Committee should address, and the

procedures that it should follow. The

reader is referred to that notice (64 FR

issues.

On December 14–15, 1999, interested

parties attended a public meeting in

Washington, DC. As part of that

meeting, the schedule of specific dates

for holding meetings of the Advisory

Committee was agreed upon. Meetings

of the Committee will be open to the

public so that individuals who are not

part of the Committee may attend and

observe. Any person attending the

Committee meetings may address the

Committee, if time permits, or file

statements with the Committee.
