Mississippi

Mississippi's Department of Environmental Quality administers the state's Brownfields program. A key
element of the program is the Brownfields Agreement, which offers liability protection to prospective
redevelopers.

In April of 2005, the state legislature passed the Mississippi Brownfields Voluntary Cleanup and
Redevelopment Incentives Act, implementing several incentives for site assessment and remediation.
The new incentives include:

A Mississippi income tax credit equal to 25 percent of the remediation costs at a Brownfield
Agreement site for the tax year in which the costs are incurred;

A job tax credit for taxes equal to the remediation costs of commercial or industrial property
owners who clean up a contaminated property. This credit is offered in lieu of the 25 percent
income tax credit described above;

Inclusion of brownfields remediation as a "capital improvement" under the Mississippi
Development Authority's Local Governments Capital Improvements Revolving Loan Program;
and

A new Local Governments Brownfields Redevelopment Grant Fund, which will also be
implemented through the Mississippi Development Authority.

application constitutes an application for the purposes of Section 49-35-7(2).

Cost effective, when applied to remediation requirements, use restrictions, or
engineering controls, means that these measures are economically and
technically feasible and practicable in protecting human health or the
environment for the intended use of a Brownfield Agreement Site.

Cumulative excess cancer risk means the upper bound on the estimated
cancer risk above the background risk associated with exposure to multiple
hazardous substances or multiple exposure pathways.

Cumulative site risk means the summation of risks to a human receptor or

algorithm to calculate the risk (dependent variable) posed by independent
variables (such as exposure factors and exposure point concentrations that
produce the intake).

4


-------
Final Brownfield Regulations
February 28, 2002

DNAPL means dense non-aqueous phase liquid.

Ecological receptor of concern means specific ecological communities,
populations, or individual organisms protected by federal or state laws and/or
regulations, or those local populations which provide important natural or
economic resources, functions and values.

Ecosystem means an integrated, self-functioning system consisting of
interactions among both the biotic community and abiotic environment within a
specified location in space and time.

Effective Solubility means the solubility of a compound that will dissolve from a
chemical mixture (e.g., gasoline). The effective solubility of a compound from a
chemical mixture is less than its aqueous solubility.

Engineering control means an existing condition or modification to a Brownfield
Agreement Site that reduces or eliminates the potential for exposure to
contaminants. These conditions or modifications may include, but are not limited
to, physical or hydraulic control measures (such as groundwater recovery
trenches and leachate collection systems), groundwater treatment systems,
engineered caps, liner systems, slurry walls, or permanent structures, but shall
not include the exclusive use of security fencing.

constituents that pose unacceptable risks to the environment, humans, or
ecological receptors.

EPA means the United States Environmental Protection Agency.

Executive Director means the Executive Director of the Mississippi Department
of Environmental Quality.

Exposure means contact of an organism with a chemical or physical agent.
Exposure is quantified by exposure point concentration in an exposure medium
(such as soil, sediment, air, groundwater, and surface water) and the intake of
the medium (expressed as the amount of the medium taken into the body by the
organism per unit body weight per day).

Exposure factors means values used to estimate exposure in risk assessment,
such as the number of days per year, number of years that exposure is expected
to occur, the amount of contaminated media that a person or an organism might
contact per day, the extent of uptake or absorption of the medium contacted, and
the body weight.

Exposure pathway means the manner by which a person or an organism may
be exposed to a chemical of concern or contaminant. A complete exposure

5


-------
Final Brownfield Regulations
February 28, 2002

pathway consists of a source, a release from a source, a migration and transport
mechanism, an exposure medium (e.g., air) or media (in cases of intermediate
transfer), an exposure point, and an exposure route.

Exposure point concentration (EPC) is the amount of CoC available at the
exchange boundaries of the organism (e.g., skin, lungs, gut) for absorption by
humans.

Exposure route means the portal of entry which results in the intake of a
contaminated medium into the human body or an organism (e.g., ingestion,
dermal contact, and inhalation).

Fate and Transport means the behavior and movement of a chemical through
an environmental media. The movement is affected by many factors such as
sunlight (UV radiation), wind-blown or wave actions, microbial activity,
groundwater and surface water flow, chemical properties (e.g., solubility,
density), physical-chemical properties of the medium (e.g., grain size, porosity,
permeability, and organic carbon content), and presence of solubility-enhancing
solvents or buried piping and utilities.

Free product means a discharged hazardous substance or environmental
pollutant that is present in the environment as a floating or sinking non-aqueous
phase liquid. Free Product is considered present if (1) measurable using best
available technologies, or (2) for groundwater, the concentration of the chemical
of concern is at or above the aqueous solubility limit for that pure compound or
the effective solubility limit for that compound in a chemical mixture, or (3) for
soils, the concentration of the chemical of concern is at or above the soil
saturation limit for that compound for all chemicals with a melting point less than
30 degrees Celsius.

Groundwater quality standard means the chemical-specific numerical value
published by EPA as Maximum Contaminant Level (MCL). Where the
groundwater intersects surface water, ambient water quality criteria values
identified in the "Mississippi Water Quality Criteria for Intrastate, Interstate, and
Coastal Waters" or other values determined by the MDEQ to be protective will be
applicable.

Habitat means the area or type of environment to which an organism or
biological population is indigenous.

Hazard index means the sum of the hazard quotients for multiple substances
and/or multiple exposure pathways.

Hazard quotient means the value which quantifies non-carcinogenic hazard for
a single chemical for an individual receptor over a specified exposure period.
The hazard quotient is equal to the ratio of an intake of a chemical to the

6


-------
Final Brownfield Regulations
February 28, 2002

chemical's reference dose. Hazard quotient shall be based on similar-acting
non-carcinogens, i.e., systemic toxicants that act on the same organ or organ
system.

Hazardous substance mean any substance which is a hazardous substance as
defined in Section 101(14) of the Comprehensive Environmental Response,
Compensation, and Liability Act of 1980, and any substance which is designated
as a hazardous substance under Section 102 of such Act.

Integrated Risk Information System (IRIS) means the database system of that
name developed and maintained by EPA.

Land-use restriction or institutional control means the limitation on use of or

access to a Brownfield Agreement Site to reduce or eliminate the potential for
exposure to contaminants. These restrictions may include, but are not limited to,
deed restrictions, use restrictions, restrictive covenants, or restrictive zoning.

Legal and Equitable Interest Owners mean persons who have a legal or
equitable interest in the Brownfield Agreement Site and may include, but are not
limited to, property owners, tenants, or lending institutions.

LNAPL means light non-aqueous phase liquid.

Local government means a county or municipality within the State of
Mississippi.

is monitored to determine achievement of remediation goals over a specified time
period.

7


-------
Final Brownfield Regulations
February 28, 2002

Natural Attenuation means the reduction in the concentration or mass of a
substance and its breakdown products in an environmental medium (such as
groundwater), due to naturally occurring physical, chemical, and biological
processes without human intervention or enhancement. These processes
include, but are not limited to, dispersion, diffusion, sorption and retardation, and
degradation processes such as biodegradation, abiotic degradation and
radioactive decay.

NAPL means non-aqueous phase liquid, which can be heavier or lighter than
water. NAPL that is lighter than water is called light non-aqueous phase liquid
(LNAPL) or a floater. NAPL that is heavier than water is called dense non-
aqueous phase liquid (DNAPL) or a sinker.

Remediation means action to cleanup, mitigate, correct, abate, minimize,
eliminate, control, treat, remove, or to implement institutional and/or engineering
controls in order to prevent the spreading, migration, leaking, leaching,
volatilization, spilling, transport, exposure, or further release of a contaminant to
the environment in order to protect public health or the environment.

Remediation goal (RG) means the target cleanup level or objective that is cost-
effective, implementable, and protective of human health and the environment.
The RG can be quantitative, i.e., numerical cleanup level (generally expressed in

exposure to carcinogens) or noncarcinogenic (from exposure to noncarcinogens,
i.e., systemic toxicants).

Risk assessment or "site-specific risk assessment" means a site-specific
characterization of the current or potential threats that may be posed to human
health and the environment by contamination migrating to or in groundwater or
surface water, discharging to the air, leaching through or remaining in soil,
bioaccumulating in the food chain, or other complete and significant exposure
pathways identified in the Site Conceptual Exposure Model (SCEM). Key
components of a risk assessment are the identification of hazard (i.e., identifying
site-related chemicals and their concentrations in the exposure media), exposure
assessment (identifying complete and significant exposure pathways and
quantifying intake), toxicity assessment (identifying the toxic effects and dose-
response [toxicity value]), risk characterization, and discussion of uncertainties.
For the purposes of these regulations, a Tier 3 Risk Assessment is considered a
"site-specific risk assessment."

10

Risk-based remediation requirement means remediation a requirement based
on public health and environmental risks specific to a Brownfield Agreement Site.

Risk Management means the evaluation of options or measures to reduce risk,
including, but not limited to, such options as no further action, monitoring only, or
gathering additional data before making a decision.

Sediment means particles in surface waters or wetlands or on the bottom of
surface waters or wetlands that are derived from the erosion of rock, minerals,
soils and biological materials, as well as chemical precipitation from the water
column. Sediment particles are transported by, suspended in or deposited by
water.

Sensitive environment means an area of exceptional environmental value,
where a discharge or release could pose a greater threat than a discharge to
other areas, including but not limited to: wetlands; habitat used by state or
federally designated endangered or threatened species; national or state fish and
wildlife refuges and fish and wildlife management areas; and state and federal
designated wild and scenic rivers.

Site Conceptual Exposure Model (SCEM) means a graphical presentation of
actual or hypothetical conditions, based on current data and understanding of the
Site, under which the chemicals of concern or contaminants from a Brownfield
Agreement Site may be released from a source, moved (migration/transport) in
the environment, present in the exposure media, and absorbed by the receptor
through the exposure routes. The SCEM will be used to identify data needs to
assess risk and may be modified to consider new data in determining whether an
exposure pathway is incomplete or complete. The SCEM is used in the
development of remediation goals and identification of remedial options.

Slope factor means the upperbound estimate of probability in the occurrence of
excess cancer risk (increase in cancer risk over the background risk) associated
with a specific carcinogen for an individual who is exposed to a unit of intake over
lifetime. The unit for a slope factor is the probability per unit intake, i.e., the
inverse of milligram per kilogram body weight (mg/Kg/day)"1.

SPLP means Synthetic Precipitation Leaching Procedure, an EPA analytical
method (Method 1312) published in SW-846.

SSL means a soil screening level developed by EPA in the Soil Screening

toxicity value used for risk characterization of the chronic effect for a systemic
toxicant is the reference dose (RfD).

Target remediation goals (TRGs) mean risk-based media concentrations
utilized in the Tier 1 evaluation of human health and environmental impacts in
these regulations. Soil TRGs are soil concentrations developed by MDEQ for
individual chemicals to address the soil ingestion and inhalation exposure
pathways and environmental risks. Groundwater TRGs are either the
groundwater quality standards (current MCLs published by EPA) or risk-based
remediation goals derived by MDEQ. Soil and groundwater TRGs are provided
in MDEQ's Risk Evaluation Procedures developed for these regulations. Surface
water TRGs are the water quality criteria published by the MDEQ. TRGs are to
be compared with the exposure point concentrations. TRGs alone do not always
trigger the need for response actions or define unacceptable levels of
contaminants n soil or groundwater. The Tier 1 TRGs may either be used as
"default" remediation goals or as screening values that will initiate a Tier 2
Evaluation or Tier 3 Evaluation.

Target risk means a de minimis or insignificant risk to humans below which
further action (remediation, institutional control, monitoring, etc.) is not warranted.

Technical Impracticability or "Technically impracticablei" means the inability
to achieve certain remediation requirements and is based on engineering
feasibility and reliability, cost-effectiveness, and risk-based considerations. For
the purposes of these regulations, EPA's OSWER Directive 9234.2-25:
"Guidance for Evaluating the Technical Impracticability of Groundwater
Restoration," dated September 1993 may be utilized in developing a
demonstration of technical impracticability with regard to groundwater and soil
remediation, free product removal, and other site-specific conditions approved by
MDEQ.

Tier 1 Evaluation means a comparison of CoC exposure point concentrations in
soil or sediment with chemical-specific TRGs for the evaluation of human health
and environmental impacts and an evaluation of ecological impacts through
completion of an Ecological Checklist. Ecological evaluations are used to
determine whether ecological receptors of concern are present and may include,
but are not limited to, the collection of field observation data for any readily
apparent harm on the ecological receptors of concern.

12

Final Brownfield Regulations
February 28, 2002

Tier 2 Evaluation means a more in-depth evaluation of site-specific conditions
beyond the Tier 1 Evaluation methodology. The Tier 2 Evaluation may include,
but is not limited to, an evaluation of site-specific conditions by (1) comparing the
UCL of the Mean for a CoC applying statistical methods to the Tier 1 TRGs, (2)
comparing EPCs to calculated background chemical concentrations, (3)
comparing EPCs to calculated regionally prevalent chemical concentrations, (4)
utilizing site-specific variables (i.e., exposure frequency, exposure duration, etc.)
to calculate site-specific RGs, (5) eliminating/minimizing exposure routes, (6)
conducting an analysis of Petroleum Hydrocarbons using TPH Fractioning, or (7)
other methods approved by MDEQ.

Tier 3 Evaluation means a site-specific risk assessment (Risk Assessment).
The Tier 3 human health risk evaluation is the characterization of the risks of
cancer and adverse non-cancer health effects in humans in accordance with

assessment guidance published by EPA including, but not limited to, the Adult
Lead Model and the Integrated Exposure Uptake Biokinetic Model (IEUBK) for
lead. The Tier 3 ecological risk evaluation is the characterization of
environmental effects qualitatively or quantitatively in accordance with the EPA's
Framework for Ecological Risk Assessment guidance, as amended.

Treatability study means the testing and documentation activities to evaluate
the effectiveness of a proposed remediation method (remedial action) prior to full
scale design and implementation. Treatability study includes, but is not limited
to, bench scale studies and pilot scale studies, and may be required by the
Corrective Action Plan if the remediation method has not been evaluated by EPA
or an independent consultant or trade association to be capable of treating the
medium (or medium of similar physical and chemical characteristics) at the
Brownfield Agreement Site.

Unacceptable risks mean that the carcinogenic risks, non-carcinogenic
hazards, or ecological risks posed by the CoCs at the point of exposure,
according to a Tier 1, Tier 2, or Tier 3 Evaluation, have exceeded established
target risk levels for humans or ecological receptors. The term can also be
applied qualitatively if there is a sufficient basis to conclude that the likelihood of
impact to the ecological receptors of concern or the sensitive environment is high
based on findings of an ecological risk assessment.

Unrestricted site, relevant to a Brownfield Agreement Site, means that the use
of the property is not restricted by an applicable Brownfield Agreement.

Volatile Compounds means those compounds with a Henry's Law Constant
greater than 1 x 10"5 and a molecular weight less than 200 g/mole, for all media.

(3)	The proposed uses of the Brownfield Agreement Site after all
remediation required by MCEQ is complete.

(4)	A schedule for administration of the Brownfield Agreement by MDEQ.

(5)	Requirements, as deemed appropriate by MCEQ, for reporting on the
progress of remediation conducted on or under the Brownfield
Agreement Site.

(6)	Requirements as deemed appropriate by MCEQ for reporting on the
status of the Brownfield Agreement Site following completion of all
remediation including the status of the institutional controls,
engineering controls and monitoring.

(7)	Any other provisions deemed necessary by MCEQ to implement the
Brownfield Agreement.

(c)	Prior to approval of the Brownfield Agreement by the Commission, the
Brownfield Party shall submit to MDEQ, on a form prescribed by MDEQ, a
statement of consent signed by all owner(s) of interests in the Brownfield
Property (other than the Brownfield Party) stating that such owners have
read and understand the Brownfield Agreement and that they consent to
the inclusion of their property interest in the Brownfield Agreement Site.

(d)	Prior to execution of the Brownfield Agreement, and with thirty days
written prior notice to MDEQ, the applicant may withdraw the Brownfield
Agreement application. The applicant shall be required to pay all costs
associated with the processing of the Brownfield Agreement application
prior to the effective date of withdrawal. Failure to pay all accrued costs
shall subject the Brownfield Party to remedies contained in Mississippi
Code Annotated Section 49-17-43. In addition, MCEQ may proceed with
any and all remedies available to it with regard to the Brownfield Property
and/or Brownfield Applicant.

Section 302. Risk-based Remediation Requirements and Land-use
Restrictions

(a) A Brownfield Agreement shall establish remediation requirements that are
based on public health and environmental risks specific to the Brownfield
Agreement Site and in accordance with Mississippi Code Annotated
Section 49-35-7. In establishing the risk-based remediation requirements
in a Brownfield Agreement, MCEQ shall consider the use of appropriate
land-use restrictions and/or engineering controls proposed by the
Brownfield Party. MCEQ may determine that permanent engineering
controls in conjunction with appropriate land-use restrictions satisfy the
remediation required by MCEQ in the Brownfield Agreement. These risk-

23


-------
Final Brownfield Regulations

February 28, 2002

based remediation requirements may include contaminant-specific, state-
specific, site-specific and/or likelihood-of-risk methodologies for the
implementation of these risk-based remediation requirements. Any party
to a Brownfield Agreement who complies with the requirements of a
Brownfield Agreement may rely on these risk-based remediation
requirements, land-use restrictions and engineering controls as governing
the extent of remediation required to be performed by the Brownfield Party
on or under the Brownfield Agreement Site for all purposes of the Act.
Any risk-based remediation requirements, land-use restrictions and
engineering controls implemented under a Brownfield Agreement shall be
conducted in a cost-effective manner, consistent with projected future
uses of the Brownfield Agreement Site.

(b)	Remediation options include, but are not limited to, the use of appropriate
land-use restrictions, engineering controls, monitored on-site containment,
excavation, monitored natural attenuation, soil vapor extraction, dual-
phase extraction, pump & treat, phytoremediation, landfarming, and/or any
other remediation option or combinations thereof approved by MCEQ.

(c)	The three procedures for determining risk-based remediation
requirements follow:

(1)Tier1 Evaluation

i.	The Tier 1 human health and environmental evaluation consists of
comparing the maximum or high-end concentrations or Minimum
Quantitation Limits (MQLs) (if results are presented as not detected
[ND]) of site-related chemicals (Chemicals of Concern [CoCs]) in
soil or sediment (and groundwater or leachate, as necessary) with
chemical-specific Target Remediation Goals (TRGs) for the
assessment of potential risks to humans. Human health TRGs,
except for surface water TRGs, are presented in MDEQ's Risk
Evaluation Procedures developed for use with these regulations.
The Tier 1 TRGs may either be used as "default" remediation goals
or may be used as a screening tool that will trigger a Tier 2
Evaluation.

ii.	The Tier 1 ecological risk screen is performed to determine whether
ecological receptors of concern are present and potentially
impacted. If they are present and potentially impacted, a Tier 3
assessment of ecological risk shall be performed to assess the
potential ecological impact. A Tier 1 Evaluation is applicable for
Sites with no known ecological receptors of concern present.

24


-------
Final Brownfield Regulations
February 28, 2002

(2) Tier 2 Evaluation

A Tier 2 Evaluation is a more in-depth evaluation of site-specific
conditions beyond the Tier 1 Evaluation methodology. The Tier 2
Evaluation may include, but is not limited to, an evaluation of site-
specific conditions by (1) comparing the UCL of the Mean for a CoC
utilizing statistical methods to the Tier 1 TRGs, (2) comparing EPCs to
calculated background chemical concentrations, (3) comparing EPCs
to calculated regionally prevalent chemical concentrations, (4) utilizing
site-specific variables (i.e., exposure frequency, exposure duration,
etc.) to calculate site-specific RGs, (5) eliminating or minimizing
exposure to contaminants, (6) conducting an analysis of Petroleum
Hydrocarbons using TPH Fractioning, or (7) other methods approved
by MDEQ.

i.	Statistical Methods - If the Brownfield Applicant can demonstrate
to the satisfaction of MDEQ that the Upper Confidence Level (UCL)
of the Mean for a CoC utilizing statistical methods is less than the
Tier 1 TRG for that CoC, then the Brownfield Applicant shall have
the option of using the UCL of the Mean instead of the highest
concentration on-site using Tier 1 Methodologies. The Brownfield
Applicant must demonstrate to the satisfaction of MDEQ that the
data are statistically normal or can be statistically normalized.

ii.	Site Background - CoC concentrations may be compared to site
background chemical concentrations to evaluate appropriate
remedial actions at the Brownfield Agreement Site in accordance
with MDEQ's Risk Evaluation Procedures. To establish
background chemical concentrations, the Brownfield Applicant may
collect samples from locations outside of the influence of known
contaminated areas and regionally prevalent chemicals and must
analyze these samples using the same analytical methods as the
CoC analyses. Sites where the concentrations of CoCs are at or
below background chemical concentrations are subject to Sections
105(e) and 202(e) of these Regulations.

iii.	Regionally Prevalent Chemicals - CoC concentrations may be
compared to regionally prevalent chemical concentrations to
evaluate appropriate remedial actions at the Brownfield Agreement
Site in accordance with MDEQ's Risk Evaluation Procedures. To
establish regionally prevalent chemical concentrations, the
Brownfield Applicant may collect samples from locations throughout
a substantial geographic region and outside the influence of known
contaminated areas and must analyze these samples using the
same analytical methods as the CoC analyses. Sites where the

25


-------
Final Brownfield Regulations
February 28, 2002

concentrations of CoCs are at or below regionally prevalent
chemical concentrations are subject to Sections 105(e) and 202(e)
of these Regulations.

iv.	Site-Specific Variables - If the Brownfield Applicant can
demonstrate to the satisfaction of MDEQ that site-specific variables
(i.e., exposure duration, exposure frequency, moisture content,
etc.) are more representative of site conditions than the default
variables utilized in the development of the Tier 1 TRGs, the
Brownfield Applicant may utilize site-specific variables to develop
RGs for the CoCs.

v.	Eliminate/Minimize Exposure Routes - If the Brownfield Applicant
can demonstrate to the satisfaction of MDEQ that land-use
restrictions and engineering controls at the site will eliminate all
complete exposure pathways or will minimize contamination
exposure to levels that will be protective of human health and the
environment, MDEQ may determine that further remediation is not
required. The Commission considers the presence of free product
to be an unacceptable potential risk to public health and the
environment because it is considered to be a continuing source of
contamination that may increase the level of risk that is the basis
for the remediation requirements, may reduce the margin of safety
provided by the remediation design, or may jeopardize the
permanence of the Brownfield Agreement. Therefore, free product
must be removed unless it can be demonstrated to the satisfaction
of MDEQ that removal of the free product is technically
impracticable. The Applicant must also demonstrate to the
satisfaction of MDEQ that the contamination is confined and will
remain confined within the site boundaries. Any monitoring plan
must be approved by MDEQ.

vi.	Tier 2 TPH Fractioning - For sites that do not meet the Tier 1 TPH
TRGs, the Brownfield Party may either (1) conduct a more detailed
evaluation of petroleum hydrocarbons using the methodology
outlined in MDEQ's Risk Evaluation Procedures or (2) conduct
another TPH risk evaluation of approved by MDEQ.

vii.	Other Approved Methods - MDEQ may approve other risk
evaluation methodologies under Tier 2.

(3) Tier 3 Evaluation

A Tier 3 Evaluation is a site-specific assessment of the baseline risk of

the Site (risk posed by the Site without remediation) based on current

EPA risk assessment guidance, specifically those published by the

26


-------
Final Brownfield Regulations
February 28, 2002

Office of Emergency and Remedial Response (Superfund program),
the Risk Assessment Forum, and selected EPA Regional Offices. In
this evaluation, an assessment of risk for all completed exposure
pathways to humans and/or ecological receptors must be calculated.

i.	Human Health Evaluation - For human health, the remediation
goal (RG) for each individual contaminant which is a carcinogen
must be calculated to attain a Risk Level of 10"6 (i.e., 1 in a million).
For a systemic toxicant, the remediation goal must be calculated to
attain a total hazard quotient of not more than 1, except with regard
to a background chemical concentration or a regionally prevalent
chemical concentration. In cases where contaminants with
corrective action concentrations established through federal and/or
state programs (i.e., Safe Drinking Water Act maximum
contaminant levels (MCLs)) are present, the MDEQ will determine
the appropriate corrective action concentration on a contaminant -
by-contaminant basis. MDEQ may consider an alternative
quantitative or qualitative remediation goal (RG) for each individual
contaminant, provided the Applicant can demonstrate to the
satisfaction of MDEQ that the attainment of a Risk Level of 10"6 for
each individual carcinogenic contaminant or a total hazard quotient
of not more than 1 for each individual systemic toxicant is
technically impracticable, except with regard to a background
chemical concentration or a regionally prevalent chemical
concentration. In no event, except with regard to background
chemical concentrations, may either the cumulative (total) site
carcinogenic risk exceed 1 x 10"4 for carcinogenic CoCs or the site
hazard index (summation of hazard quotients) exceed 3 for non-
carcinogenic CoCs affecting the same organ or organ system.

ii.	Ecological Evaluation - For the assessment of ecological risk, the
maximum or high-end soil, sediment, or surface water data must be
compared with threshold or benchmark values for the protection of
the ecological receptors of concern. The Brownfield Applicant must
demonstrate either that the concentration of the affected media is
below the threshold or benchmark values or that the hazard
quotient for the individual CoCs is below 1 utilizing the quotient
method.

(d) Risk-based remediation goal - The risk-based remediation goal (RG)
may be qualitative or quantitative. A qualitative RG involves the exclusion
of exposure pathways by engineering controls. A quantitative RG involves
calculating the maximum numerical CoC(s) concentration in a medium
which would not exceed the acceptable baseline risk at the exposure
point. The numerical risk-based RG may be adjusted upward or

27


-------
Final Brownfield Regulations

February 28, 2002

downward depending on risk management considerations as approved by
the MDEQ.

(e)	Free Product - Free Product refers to the presence of a hazardous
substance or an environmental pollutant in the environment as a floating
or sinking non-aqueous phase liquid. Free Product is considered present
if measurable using best available technologies or if the concentration of
the chemicals of concern in groundwater or soils is at or above the
solubility limit for all chemicals or soil saturation limit for all chemicals with
a melting point less than 30 degrees Celsius. On a site-specific basis,
MDEQ may require either the effective solubility or the aqueous solubility
to be utilized. Free product must be removed from the Brownfield
Agreement Site, unless it can be demonstrated to the satisfaction of
MDEQ that removal of the free product is (1) technically impracticable and
that (2) the contamination is confined and will remain confined within the
site boundaries.

(f)	Historical data - Historical data approved by MDEQ may be submitted in
lieu of collecting new data provided the Site characterization data
requirements are summarized and presented in accordance with the Site
Characterization Work Plan and Report Formats and the data was
collected in a manner consistent with appropriate sampling protocols. All
detailed information must be referenced in the reports including sampling
protocols. In any event, relevant historical Site characterization reports
shall be submitted with the application.

(g)	Site Conceptual Exposure Model (SCEM) - The Brownfields Applicant
must complete a BASELINE SCEM and a REMEDIAL SCEM on the forms
prescribed by MDEQ as described in MDEQ's Risk Evaluation
Procedures.

(h)	Petroleum Hydrocarbons - Brownfield Agreement Sites impacted with
petroleum compounds must assess the area(s) and media of impact for
petroleum hydrocarbon compounds (e.g., benzene, toluene,
ethylbenzene, total xylenes, and polynuclear aromatic hydrocarbons). In
areas where the concentration of these constituents cannot be determined
due to dilution, and/or interference, the Brownfield Applicant may either (1)
use the petroleum hydrocarbon methodologies as established in MDEQ's
Risk Evaluation Procedures or (2) another TPH risk evaluation
methodology approved by MDEQ.

(i)	Land-Use Restrictions - Before conducting the risk-based evaluation
and/or corrective action, if applicable, land-use for the Brownfield
Agreement Site shall be proposed by the Applicant, in consultation with
MDEQ, as either restricted or unrestricted.

28


-------
Final Brownfield Regulations
February 28, 2002

(1)	Unrestricted land-use - The unrestricted land-use designation is
available to property with contaminant concentrations at or below the
Tier 1 table concentrations (provided in MDEQ's Risk Evaluation
Procedures) for unrestricted land-use.

(2)	Restricted land-use - Brownfield Property that has contaminant
concentrations that exceed the unrestricted contaminant concentration
values in the Tier 1 table provided in MDEQ's Risk Evaluation
Procedures are classified as restricted. A Brownfield Agreement
regarding restricted property must require the creation of a land use
restriction referenced in the Brownfield Agreement and in the deed
notice, entitled the Notice of Brownfield Agreement Site. The
Brownfield Agreement, any required Consent Forms, and the Notice of
Brownfield Agreement Site must be filed by the Brownfield Party in the
appropriate county courthouse. The Notice of Brownfield Agreement
Site must identify the contaminant(s) present at the Site above the Tier
1 table for unrestricted land-use, the media affected, and delineate the
vertical and horizontal extent of the contaminant(s) on the Brownfield
Property. If the contaminant(s) concentration is at or below the Tier 1
table concentration for restricted land-use, or at or below the site-
specific Tier 2 or Tier 3 calculated concentration for restricted land-use,
specific restrictions including, but not limited to, property access,
property use, or property activities (with an acceptable human
exposure duration) shall be stated in the Notice of Brownfield
Agreement Site. In addition, the description, location, and
maintenance, if applicable, of any engineering controls shall be
included in the Notice of Brownfield Agreement Site.

Chapter 5. DECISION ON BROWNFIELD AGREEMENT

Section 501. Decision on Brownfield Agreement

(a)	The approval of a Brownfield Agreement shall be based on a complete
application which MDEQ determines to contain all information required
under the Act or these regulations. If MCEQ finds that the proposed
Brownfield Agreement complies with the Act and these regulations, the
MCEQ, by order, shall approve the proposed Brownfield Agreement. After
approval of the Brownfield Agreement, the Executive Director and the
Brownfield Party shall execute the Brownfield Agreement.

(b)	MCEQ may consider an Applicant's financial resources, technical
resources, managerial resources and compliance history in determining
whether or not to approve a Brownfield Agreement.

(c)	Prior to approval of the Brownfield Agreement, MCEQ may require the
applicant to demonstrate to the satisfaction of MCEQ that contamination
(the source of which is not environmental contamination or activities on or
under the Brownfield Property that is the subject of the application but
which is contributing or potentially contributing to contamination on or
under the Brownfield Property that is the subject of the application) will not
migrate onto the Brownfield Property or otherwise compromise the level of
remediation of the Brownfield Property required by the Brownfield
Agreement. This demonstration may include institutional controls,
engineering controls or other preventive measures. In the event
information is presented to MCEQ that migration of contamination has
occurred or the level of remediation required under the Brownfield
Agreement is being compromised, MCEQ may reopen the Brownfield
Agreement.

(d)	MDEQ shall consider all environmental contamination on or under the
Brownfield Property that is the subject of the application to be attributed to
activities on or under said Property, unless the Brownfield Applicant can
demonstrate to the satisfaction of MDEQ that (1) the source of
environmental contamination is off-site and (2) that conditions on or under
said Property have not and will not exacerbate or contribute to the
contamination. MCEQ may, as it deems appropriate, inspect or require
inspections; investigate or require investigations; evaluate or require
evaluations; and/or issue orders regarding properties which are a source
of contamination on or under the Brownfield Agreement Site.

(e)	MCEQ may enter into a Brownfield Agreement as proposed by MDEQ or
may modify that agreement before entering into it. MCEQ subsequently
may modify any Brownfield Agreement by entry of an order. The MCEQ

regulations, the seller of Brownfield Property shall disclose in the contract
for the purchase of the Brownfield Property that the property is Brownfield
Property and subject to a Brownfield Agreement.

Section 503. Notice by Brownfield Party of Conveyance of Brownfield
Property

Until the Executive Director issues a "no further action" letter under Section 702
of these regulations, the Brownfield Party shall submit written notice to MCEQ at
least thirty days prior to any sale, conveyance or other change in surface
ownership of any portion of the Brownfield Agreement Site. Approval from
MCEQ shall be required for any sale, conveyance or other change in surface
ownership of any portion of the Brownfield Agreement Site owned by the
Brownfield Party desiring to make the change in ownership, if the new surface
owner will be required to or will assume an obligation to perform any obligations
under the Brownfield Agreement. In that case, the Brownfield Party and the new
surface owner jointly shall provide information satisfactory to MCEQ that the new
surface owner has the financial, managerial and technical resources to complete
performance of the Brownfield Agreement obligations to be transferred and that
the new surface owner agrees to complete this performance. The new surface
owner shall also submit a statement to MDEQ on a form prescribed by MDEQ
which sets forth the requirements of the Brownfield Agreement for which it
accepts responsibility. The Brownfield Party shall remain responsible for the

contamination that has not been remediated to standards required
applicable federal or state law other than these regulations. The
Brownfield Agreement may be amended to include remediation of any
previously unknown contaminants and any additional areas in the
same Brownfield Agreement Site;

(3)	The level of risk to public health or the environment resulting from the
Brownfield Agreement Site is increased beyond the level that forms a
basis for the risk-based remediation requirements in the Brownfield
Agreement due to changes in exposure conditions, including:

i.	A change in land-use at the Site or contiguous to the Site
that increases the probability of exposure to contaminants on
or under the Brownfield Agreement Site; or

ii.	The failure of remediation to mitigate risks to the extent
required to make the Brownfield Agreement Site fully
protective of public health and the environment as provided
in the Brownfield Agreement.

SUBPART II. RISK EVALUATION PROCEDURES
Chapter 1. GENERAL
Section 101. Introduction

(a)	The Mississippi Brownfields Voluntary Cleanup and Redevelopment Program
(Brownfields Program) utilizes risk-based criteria for Site evaluation and
remediation. The risk-based procedures and rationale for evaluating environmental
contamination on or under a Site are presented in this Subpart II. This evaluation is
necessary to develop remediation requirements that are protective of human health
and the environment. All remediation and/or corrective actions must be approved
by MDEQ.

(b)	In considering the risk-based evaluation of conditions on or under a Site, the
following must be addressed:

(1)	complete the Site Conceptual Exposure Model (SCEM) to evaluate site-
specific risk and exposure conditions before and after remediation;

(2)	conduct a Site Characterization to delineate the nature and extent (vertically
and horizontally) of contamination found on or under the Site;

(3)	complete the Site Ecological Checklist to determine whether an ecological
risk assessment is necessary; and

(4)	conduct a Risk-Based Evaluation of the Site utilizing the Brownfields
Program three-tiered approach.

(c)	The cornerstone of the Brownfields Program is a three-tiered risk-based process for
evaluating human health and environmental risks. These tiers are referred to as
Tier 1, Tier 2, and Tier 3. These tiers are designed to allow the Applicant to
evaluate and determine appropriate remedial options for site specific conditions. A
description of each tier is discussed below.

(1)	A Tier 1 Evaluation is the comparison of site-specific data to a "look-up"
table of chemical-specific target remediation goals (TRGs). Specific TRG
concentrations have been determined to be protective of human health and
the environment for restricted use and unrestricted use of a Site. The Tier 1
TRG Table is presented in Appendix A.

(2)	A Tier 2 Evaluation provides the Applicant the option of performing a more
in-depth evaluation of site-specific conditions to develop site-specific
Remediation Goals (RG) and/or to better define site-specific data to be used
for a Tier 1 Evaluation.

1


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

(3) A Tier 3 Evaluation is a site-specific risk assessment to evaluate the

potential human health and ecological risks at the Site that will result in the
development of site-specific Remediation Goals (RGs).

(d)	Land use plays an integral role in the three-tiered approach and in the development
of the SCEM. Land-use restrictions may reduce or eliminate the potential for
exposure to contaminants and risk.

(e)	Specific criteria for evaluating Sites impacted with petroleum hydrocarbons is
contained in Chapter 7 of this Subpart II.

Chapter 2. BROWNFIELD SITE EVALUATION

Section 201. Site Conceptual Exposure Model (SCEM)

(a)	The SCEM is a graphical representation of actual and potential Site conditions
based on available data and an understanding of those Site conditions. A
BASELINE and a REMEDIAL SCEM must be completed and are provided in forms
prescribed by MDEQ. The BASELINE SCEM represents the risk and exposure
conditions that exist prior to the implementation of remediation. The REMEDIAL
SCEM represents the risk and exposure conditions that exist or are expected to
exist after the implementation of remediation. Items to be identified in the SCEM
include the following:

(1)	chemical of concern (CoC) sources;

(2)	CoC movement (migration/transport);

(3)	the actual or potential exposure pathways; and

(4)	the actual or potential receptor populations.

(b)	Based on the results of the completed BASELINE SCEM, exposure point
concentrations (EPCs) must be identified for CoC(s) with completed and potentially
completed exposure pathways. EPCs are the concentrations of site-related
compounds in a specific media that a human or environmental receptor will contact
(Complete) or may potentially contact (Potentially Complete) through ingestion or
inhalation at the point of exposure.

(c)	All four elements identified in the SCEM must be complete for exposure to occur. It
is important to note that the BASELINE SCEM should be developed early in the
process (i.e., Brownfield Application and/or work plan stage) and identified as
"draft" if additional information is pending. The BASELINE SCEM can be updated
and modified as the site investigation progresses and more site-specific information
becomes available. BASELINE SCEM should be identified as "final" once the Site
Characterization is complete.

(d)	If additional issues of concern pertaining to exposure at the site (additional
pathways, media, sources, transport mechanisms, receptors, etc.) are not

2


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

specifically addressed in the SCEMs, the Applicant should provide an
attachment(s) to the appropriate SCEM discussing the additional issues.

(e)	The BASELINE and REMEDIAL SCEM worksheets must be included as part of the
Site Characterization Report and the Corrective Action Report.

(f)	The procedures for completing the SCEMs follow:

(1)	Identify the Primary Sources (on-site and off-site) of contamination that exist
or are believed to have existed.

(2)	Identify the Secondary Sources. Mark the media (soils, groundwater,
sediments, or surface water) that have been impacted (Complete) or could
potentially be impacted (Potentially Complete) by a release from a primary
source.

(3)	Identify the Transport Mechanisms by which the contaminants may move
through the environment.

(4)	Identify the Exposure Pathway that is the medium (soil, groundwater, air,
sediments, or surface water) that a receptor will contact (Complete) or may
contact (Potentially Complete).

(5)	Identify the Actual (Complete) and the Future (Potentially Complete)
Receptors for restricted and unrestricted land-use.

Section 202. Criteria For Completing The SCEMs

(a) BASELINE SCEM - The following sections describe the criteria for evaluating the
completeness and potential completeness of contaminant exposure for the Site. All
potential exposure pathways should be evaluated for completeness, as identified in
the SCEM worksheets. The Applicant should provide as much detail as possible.
Indicate all sources, transport mechanisms, pathways and receptors that are
complete or potentially complete. If information is not available to support a
pathway as incomplete then that pathway should be considered to be potentially
complete and should be identified for evaluation until such information becomes
available. A description of each of the BASELINE SCEM criteria is provided in the
following sections.

(1) Sources can be defined as either Primary Sources or Secondary Sources.
Primary Sources are those present or past storage units (i.e., tanks,
impoundments, piles), distribution systems (i.e., piping, manifolds, lines,
pumps), operations (i.e., wash areas, repair bays, water treatment, blending
tanks, formulation areas), waste management units (i.e., burn pits, disposal
units, dumps) and other on-site and off-site sources of actual or potential
contamination that have or may have leaked, leached, spilled, or otherwise
been released and may have impacted the Site. Several categories of
potential primary sources are included on the SCEM worksheet and can be
identified by filling in the appropriate boxes on the worksheet. If the sources

3


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

listed do not pertain to the Site, then use "Other". The Applicant should be
as specific as possible about the source of contamination. Supporting
documentation (i.e., analytical results, product storage/transmission
information, tank information, etc.) of the primary source of contamination
should be provided in the appropriate section(s) of the Work Plan and/or Site
Characterization Report.

Secondary Sources are defined as transport media (i.e., surficial soils,
subsurface soils, groundwater, sediments, or surface water) that have been
impacted or potentially impacted by the primary (release) source. Identify all
media that may serve as secondary sources of contamination. For the
purposes of this Subpart II, surficial soil is defined as extending to 6 ft. below
ground surface (bgs). The presence of CoCs that cannot be attributed to
background should be identified as "complete," and any secondary source
that is potentially affected by an on-site or off-site primary source should be
identified as "potentially complete." The Applicant must provide adequate
documentation to demonstrate that a secondary source has not been
affected in order to remove that medium from further consideration. If such
documentation has not yet been gathered to support the exclusion of a
secondary source, then that medium must be identified as "potentially
complete" until such time as such information becomes available. The
BASELINE SCEM can be updated as additional site-specific data are
gathered.

(2) Transport Mechanisms are means by which the CoC release can migrate
from the identified secondary sources and result in actual or potential human
exposure. A variety of potential transport mechanisms are generally
applicable to a site. Indicate on the BASELINE SCEM Worksheet those
transport mechanisms that are applicable or potentially applicable to the site.
Those transport mechanisms identified as applicable or potentially
applicable should be marked "complete" or "potentially complete,"
respectively.

i. Surficial Soils - If surficial soil has been identified as a secondary
source, then the following transport mechanisms must be identified as
"complete" or "potentially complete":

(A)	Wind Erosion and Atmospheric Dispersion (For Non-Volatile
Compounds Only)

(B)	Volatilization and Atmospheric Dispersion (For Volatile Compounds
Only)

(C)	Volatilization and Enclosed-Space Accumulation (For Volatile
Compounds Only)

(D)	Leaching and Groundwater Transport

4


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

Note: The Soil Exposure Pathway must also be identified as
"complete" or "potentially complete" if surficial soil has been identified
as a secondary source.

ii.	Subsurface Soils - If subsurface soil has been identified as a secondary
source, then the following transport mechanisms must be identified as
"complete" or "potentially complete":

(A)	Volatilization and Enclosed-Space Accumulation (For Volatile
Compounds Only)

(B)	Leaching and Groundwater Transport

iii.	Groundwater - If groundwater has been identified as a secondary
source, then the following transport mechanisms must be identified as
"complete" or "potentially complete":

(A)	Volatilization and Enclosed-Space Accumulation (For Volatile
Compounds Only)

(B)	Leaching and Groundwater Transport

iv.	Sediments or Surface Water - If sediment or surface water has been
identified as a secondary source, then Surface Water Runoff or Surface
Water Transport must be identified as "complete" or "potentially
complete."

(3) Exposure Pathways are the processes by which human uptake or
exposure to site-related compounds may occur. Identify all "complete" or
"potentially complete" exposure pathways at the Site that may provide a
means for human exposure. All exposure pathways should be identified as
potentially complete if supporting information for the exclusion of the
pathway is not currently available.

i.	Soil - If surficial soils are affected, then direct exposure through
incidental ingestion must be indicated as complete or potentially
complete. Contamination in surface and subsurface soils may be
available for exposure through direct contact during intrusive activities,
such as construction. The future use of the site and any plans for
construction should be considered when evaluating the completeness of
direct contact to subsurface soils.

ii.	Air - Contamination of surface soil provides the potential for human
uptake or exposure through inhalation of vapor from volatile compounds
and through inhalation of non-volatile compounds that have adsorbed to
surface soil particulates. Contamination of subsurface soil provides the
potential for human uptake or exposure through inhalation of vapor from
volatile compounds (i.e., migration into basements or during intrusive
activities such as construction) and through inhalation of non-volatile
compounds that have adsorbed to subsurface soil particulates during

5


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

intrusive activities, such as construction. In addition, the presence of
volatile compounds in groundwater at the site produces the potential for
volatilization into air (i.e., migration into basements, depth to groundwater
is less than six (6) feet or intrusive activities).

iii.	Groundwater - Contamination of groundwater requires that the
Groundwater Exposure Pathway be marked as "complete" in the
BASELINE SCEM. Surface and subsurface soils capable of leaching
into groundwater at levels above the Groundwater TRG require that the
Groundwater Exposure Pathway be marked as "complete" in the
BASELINE SCEM. The presence of CoCs in surface and subsurface
soils requires that the Groundwater Exposure Pathway be marked as
"potentially complete" in the BASELINE SCEM. The Applicant must
provide adequate documentation to demonstrate that CoCs in surface
and subsurface soils will not leach into groundwater in order to remove
that medium from further consideration. If documentation has not been
gathered to support the exclusion of exposure pathway, that pathway
must be identified as "potentially complete." The BASELINE SCEM can
be updated as additional site-specific data are gathered.

iv.	Surface Water - The exposure pathways applicable to surface water are
included in the SCEM Worksheet in order to protect surface water bodies
that may be used for domestic or recreational purposes. The presence
of site-related compounds in soils, sediments, surface water, or
groundwater provides the potential for migration or discharge to either
on-site or off-site surface water bodies that may be used for recreational
purposes, for a potable water supply, or for livestock watering. If
contaminants are present in onsite media and such a surface water body
is present within 500 ft. of the Site boundary, the pathway should indicate
"potentially complete." Provide documentation in the Work Plan and/or
the Site Characterization Report that a water body is not associated with
or affected by the Site.

(4) The identification of Potential Receptor populations at the site is an

important part of the completion of the BASELINE SCEM. It is important to
know as much about the current and potential future use of the site and
receptor populations, as possible. The receptor populations and the planned
future use of the site are integral in supporting the remedial options at the
site. Any and all potential receptor populations that could be exposed to
site-related compounds should be identified on the BASELINE SCEM.

(b) REMEDIAL SCEM - Once the BASELINE SCEM has been completed, remedial
options (i.e., institutional controls, engineering controls, or active cleanup) for the
Site that can "shut off" or eliminate exposure to contamination should be evaluated.
Those complete and potentially complete exposure routes linking sources to
receptor populations must be remediated using one or a combination of options.

6


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

Free product must be remediated in a manner consistent with Section 601(d)(4) of
this Subpart II. The REMEDIAL SCEM includes shut-off valves to graphically
depict "open" or "closed" pathways between contaminated media and the receptor
population. Shut-off valves are marked (shut) to indicate the remedial action that
has been taken or proposed for the Site. A description of the types of remedial
actions follow:

(1)	Institutional Controls - The use of institutional controls (land use restrictions
and agreed order with MDEQ) can serve as barriers in preventing future contact
with subsurface soils and groundwater. Site land-use may be "unrestricted" or
"restricted" that relates generally to residential and industrial/commercial,
respectively. The potential to restrict the future use of the site (example: use of
the site to a defined industrial use only, or the limitations of future construction
activities, prohibiting groundwater use) can be considered in the remediation of
the Site. If no restrictions for future use will be placed on the property by the
Applicant, the identified remediation goals will be based on the future
unrestricted (residential) use of the Site. Documentation of the institutional
controls must be provided to support the proposed site remediation. A land use
restriction and agreed order with MDEQ shall be used for "restricting" the Site.
Institutional controls are to be used to "shut off" exposure to contamination. The
Site Characterization Report and/or Corrective Action Plan must document the
appropriate restrictions to be implemented. The Institutional Control Shut-off
Valve on the REMEDIAL SCEM should be marked to reflect this option. An
institutional control by itself cannot be used if there is further migration and/or
expansion of the contamination.

(2)	Engineering Controls - The use of engineering controls can reduce or
eliminate the potential for exposure to contaminants through containment.
Engineering Controls may include, but are not limited to, physical or hydraulic
control measures (such as groundwater recovery trenches and leachate
collection systems), groundwater treatment systems, engineered caps, liner
systems, slurry walls or permanent structures, but shall not include the
exclusive use of security fencing. Ingestion and dermal contact of soil
contamination that exists under a building may be considered "shut off"
provided the institutional control restricts the removal of the slab, thus
eliminating the future potentially complete exposure route to soil contamination
via ingestion or dermal contact. If an engineering control is used to "shut-off"
exposure to contamination, the Site Characterization Report and/or Corrective
Action Plan must document the appropriate engineering control and/or
institutional control to be implemented. The Engineering Control Shut-off Valve
on the REMEDIAL SCEM should be marked to reflect this option. An
institutional control must be coupled with the engineering control to ensure the
engineering control is maintained until the site is remediated to an unrestricted
level.

7


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

(3) Active Cleanup - The active cleanup (i.e., removal, treatment) of contamination
to levels that are protective of human health and the environment can reduce or
eliminate the potential for exposure to contaminants. If active cleanup is used to
"shut off" exposure to contamination, the Site Characterization Report and/or
Corrective Action Plan must document the active cleanup activities and/or
institutional control to be implemented. The Active Cleanup Shut-off Valve on
the REMEDIAL SCEM should be marked to reflect this option. An institutional
control may be necessary, depending upon the projected length of the cleanup,
particularly if groundwater has been impacted (e.g., pump and treat system has
been installed and projected to continue for 30 years).

Section 203. Site Characterization

(a)	A Site Characterization must be conducted to delineate the nature and extent
(vertically and horizontally) of contamination on and under the Site. Site
characterization data should be collected and presented in accordance with the
Quality Assurance Project Plan (QAPP) and Site Characterization Report formats.
In general, the Applicant must demonstrate that the data are representative of the
actual and/or potential contamination conditions at the Site. Collected data must
include information describing and delineating the contaminant source area.
Information pertaining to the characteristics of the CoCs, including the chemical
and physical properties as well as the potential of the CoCs to migrate and
transport to receptor locations through or in the affected media, must also be
provided.

(b)	The degree of contamination in surface and subsurface soil should be determined
by performing soil boring(s) down to the depth of groundwater in the saturated
zone. Surface soil is defined as the soil located at the surface and extending to a
depth of six (6) feet below the ground surface. The subsurface soil depth is any
depth beyond six feet. The Applicant must address ingestion, potential dermal
contact, and inhalation (through volatilization and particulates) of hazardous
chemicals present in the surface soil. In addition, CoCs in the surface soil may be
transported off-site through precipitation runoff.

(c)	The Applicant must demonstrate that groundwater is not impacted by the site-
related contaminant; or that if groundwater is impacted, the impacted groundwater
is confined and will remain confined within the Site. Groundwater contaminant
concentrations should be determined by collecting groundwater samples.

(d)	Measured data are those data collected from temporary or permanent (monitoring)
wells. The Applicant should install wells, as necessary, to delineate the vertical and
horizontal extent of groundwater impact and to determine flow direction and
groundwater quality. Wells must be installed, developed, purged, and sampled in
a manner consistent with EPA Region IV, Science and Ecological Support Division,
Environmental Investigations Standard Operating Procedures and Quality

8

Final Brownfield Regulations
Subpart II
February 28, 2002

Assurance Manual, May 1996, as amended, or other procedures approved by
MDEQ. Measured groundwater data must be based on unfiltered groundwater
samples.

(e)	The site characterization data should be collected in accordance with data quality
objectives (DQOs) stipulated in the QAPP. The DQOs shall, at a minimum, identify
the number of field and quality control samples, quantitation limits, analytical
methods, and sample collection, preservation, and handling methods. Matrix
interferences shall be minimized to the extent feasible by modified sample
extraction and preparation methods in accordance with EPA or MDEQ approved
analytical methodologies.

(f)	The data collection strategy should be based on the Site Conceptual Exposure
Model (SCEM) that hypothesizes or describes how the source chemicals or CoCs
are released, transported, and exposed to the receptors.

(g)	The Applicant must demonstrate that the analytical laboratory data have been
reviewed for compliance with the DQOs. In the Site Characterization Report, the
Applicant shall identify data that meet DQOs.

(h)	To establish background chemical concentrations, the Applicant may collect
samples from locations, as approved by MDEQ, outside of the influence of known
contaminated areas and regionally prevalent chemicals and must analyze these
samples using the same analytical methods as the CoC analyses.

(i)	To establish regionally prevalent chemical concentrations, the Applicant may collect
samples from locations, as approved by MDEQ, throughout a substantial
geographic region and outside the influence of known contaminated areas and
must analyze these samples using the same analytical methods as the CoC
analyses.

(j) Historical data approved by MDEQ may be submitted in lieu of collecting new data
provided that: (1) the Site characterization data requirements are summarized and
presented in accordance with the Quality Assurance Project Plan and Site
Characterization Report Formats; and (2) the data was collected in a manner
consistent with appropriate sampling protocols, as approved by MDEQ. All detailed
information must be referenced in the reports including sampling protocols. In any
event, relevant previous site characterization reports should be submitted along
with the application. Deviations from the required methodologies in the Quality
Assurance Project Plan, Site Characterization Report, or Corrective Action Plan
formats must be presented to and approved by MDEQ.

Section 204. Site Ecological Checklist

The Ecological Checklist is used to determined if ecological receptors of concern are
present and potentially impacted (See Appendix D). If such receptors are present, MDEQ
will make a determination as to whether a Tier 3 assessment of ecological risk should be
performed to assess the potential ecological impact. Tier 1 and Tier 2 Evaluations are
applicable for Sites with no known ecological receptors of concern.

Chapter 3. TIER 1 EVALUATION

Section 301. Tier 1 Evaluation Target Risk Level

The TRGs presented in the Tier 1 TRG table, Appendix A, are based on either (1) a 1x10"6
target risk level for each carcinogenic chemical, (2) a hazard index not to exceed 1 for
each systemic toxicant, or (3) constituent TRG concentrations established through
federal/state programs (i.e., Safe Drinking Water Act). The values presented in the Tier 1
TRG table will be modified periodically based on EPA updates of toxicity values obtained
from the sources presented in Section 502(c)(2) of this Subpart II.

Section 302. Tier 1 Evaluation Procedures

(a)	The basic methodology for a Tier 1 Evaluation shall be the comparison of the
highest concentration of each contaminant in each media to the TRGs provided in
the Tier 1 TRG table. Results of the comparison will be used to determine if the
site specific data are:

(1)	at or below the unrestricted risk value;

(2)	above the unrestricted risk value, but at or below the restricted risk value; or

(3)	above the restricted risk value.

(b)	Sites that do not require an ecological evaluation beyond the Site Ecological
Checklist and that exhibit chemical concentrations that are at or below the
unrestricted TRGs do not require further evaluation or action. Such sites are not
eligible for the Brownfields Program since remediation is not necessary as required
in Section 49-5-5(b) of Mississippi Code Annotated, as amended.

(c)	Sites with chemical concentrations in soils that are greater than the unrestricted
TRGs but below the restricted TRGs may:

(1)	clean-up and/or remove the affected media to a value at or below the
unrestricted TRG values resulting in an unrestricted land-use site;

(2)	implement appropriate institutional controls (i.e., land use restriction and agreed
order with MDEQ) resulting in a restricted land use site; or

(3)	perform a Tier 2 Evaluation.

(d)	Sites with chemical concentrations in soils that exceed the restricted TRGs may:

(1)	clean-up and/or remove the affected media to a value at or below the
unrestricted TRG values resulting in an unrestricted land use site;

(2)	clean-up and/or remove the affected media to a value at or below the restricted
TRG values but above the unrestricted TRG values resulting in a restricted land
use site and implement appropriate institutional controls (i.e., land use
restriction and agreed order with MDEQ); or

(3)	perform a Tier 2 Evaluation.

(e)	Sites with chemical concentrations in groundwater that are greater than the
unrestricted TRGs may:

(1)	clean-up the affected media to a value at or below the unrestricted TRG values
resulting in an unrestricted land-use site;

(2)	implement appropriate institutional controls (i.e., land use restriction and agreed
order with MDEQ) resulting in a restricted land use site; or

(3)	perform a Tier 2 Evaluation.

(f)	MDEQ may consider utilizing the Method Detection Limit (MDL) in place of the
Target Remediation Goal (TRG) on a case by case basis.

(g)	In areas of a site where chemical concentrations of petroleum hydrocarbon
indicator compounds (e.g., BTEX, PAHs, MTBE) are not quantifiable to the Tier 1
TRGs (e.g., dilution and/or matrix interference) may:

(1)	use the Tier 1 TRGs for TPH-GRO/DRO for performing a Tier 1 Evaluation; or

(2)	perform a Tier 2 TPH Fractioning Evaluation.

Chapter 4. TIER 2 EVALUATION

Section 401. Tier 2 Evaluation Target Risk Level

For human health, the remediation goal (RG) for each individual contaminant which is (1)
a carcinogen must be calculated to attain a Risk Level of 10"6 (i.e., 1 in a million) and (2) a
systemic toxicant must be calculated to attain a total hazard quotient of not more than 1
except with regard to a background chemical concentration or a regionally prevalent
chemical concentration. In cases where contaminants with corrective action
concentrations established through federal and/or state programs (i.e., Safe Drinking
Water Act maximum contaminant levels (MCLs)) are present, the MDEQ will determine
the appropriate corrective action concentration on a contaminant by contaminant basis. In
no event, except with regard to a background chemical concentration, may either (1) the
cumulative (total) site carcinogenic risk exceed 1 x 10"4for carcinogenic CoCs or (2) the
site hazard index (summation of hazard quotients) exceed 3 for non-carcinogenic CoCs

Subpart II
February 28, 2002

affecting the same organ or organ system without the use of both an engineering control
and an institutional control.

Section 402. Tier 2 Evaluation Options

(a) Tier 2 Evaluation is a more in-depth evaluation of site-specific conditions beyond
the Tier 1 Evaluation methodology. The Tier 2 Evaluation may include, but is not
limited to, an evaluation of site-specific conditions by (1) determining the Upper
Confidence Limit (UCL) of the Mean for a CoC utilizing statistical methods and
comparing the UCL to the Tier 1 TRGs, (2) comparing EPCs to calculated
background chemical concentrations, (3) comparing EPCs to calculated regionally
prevalent chemical concentrations, (4) utilizing site-specific variables (i.e., exposure
frequency, exposure duration, etc.) to calculate site-specific RGs, (5) eliminating or
minimizing exposure to contaminants, (6) conducting an analysis of Petroleum
Hydrocarbons using TPH Fractioning, or (7) utilizing other methods approved by
MDEQ.

(1)	Statistical Methods - If the Applicant can demonstrate to the satisfaction of
MDEQ that the UCL of the Mean for a CoC utilizing statistical methods is
less than the Tier 1 TRG for that CoC, this calculated value may be used
instead of the highest CoC concentration. The UCL of the Mean is then
compared to the Tier 1 TRG to evaluate remedial options. The Applicant
must demonstrate to the satisfaction of MDEQ that the data are statistically
normal or can be statistically normalized.

i. The methodology used to determine the UCL of the Mean should be
conducted in accordance with the EPA's Supplemental Guidance to
RAGS: Calculating the Concentration Term (EPA, 1992a), or another
method approved by MDEQ.

(2)	Site Background - CoC concentrations may be compared to site
background chemical concentrations to evaluate appropriate remedial
actions at the Site.

i.	To establish background chemical concentrations, the Brownfield
Applicant may collect samples from locations outside of the influence of
known contaminated areas and regionally prevalent chemicals (both
vertically and horizontally), as approved by MDEQ and must analyze
these samples using the same analytical methods as the CoC analyses.

ii.	If the Applicant can establish that the background chemical concentration
of a CoC is higher than the Tier 1 TRG concentration for that CoC listed
in Appendix A, the Applicant shall have the option of using the
background chemical concentration as the Remedial Goal (RG).

12


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

iii.	Remediation of a CoC above its established background chemical
concentration will not be necessary.

iv.	The methodology used to determine background chemical
concentrations in soil shall be conducted in accordance with EPA's
Engineering Forum Issue: Determination of Background Concentrations
of Inorganics in Soils and Sediments at Hazardous Waste Sites
(EPA/540/S-96/500), December 1995, or another method approved by
MDEQ.

v.	The methodology used to determine background chemical
concentrations in groundwater shall be conducted in accordance with
EPA's Guidance Document on the Statistical Analysis of Ground-Water
Monitoring Data at RCRA Facilities (EPA/530/SW-89/026), April 1989, or
another method approved by MDEQ.

(3) Regionally Prevalent Chemicals - CoC concentrations may be compared
to regionally prevalent chemical concentrations to evaluate appropriate
remedial actions at the Site.

i.	To establish regionally prevalent chemical concentrations, the Brownfield
Applicant may collect samples from locations throughout a substantial
geographic region and outside the influence of known contaminated
areas, as approved by MDEQ, and must analyze these samples using
the same analytical methods as the CoC analyses.

ii.	If the Applicant can establish that the concentration of a CoC is higher
than the concentration of a regionally prevalent chemical, the Applicant
shall have the option of using the concentration of the regionally
prevalent chemical as the Remedial Goal (RG) provided (1) the
cumulative (total) site carcinogenic risk does not exceed 1 x 10"4for all
on-site carcinogenic CoCs and (2) the site hazard index (summation of
hazard quotients) does not exceed 3 for all on-site non-carcinogenic
CoCs that affect the same organ or organ system.

iii.	The methodology used to determine regionally prevalent chemical
concentrations in soil shall be conducted in accordance with EPA's
Engineering Forum Issue: Determination of Background Concentrations
of Inorganics in Soils and Sediments at Hazardous Waste Sites
(EPA/540/S-96/500), December 1995, or another method approved by
MDEQ.

iv.	The methodology used to determine regionally prevalent chemical
concentrations in groundwater shall be conducted in accordance with
EPA's Guidance Document on the Statistical Analysis of Ground-Water

13


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

Monitoring Data at RCRA Facilities (EPA/530/SW-89/026), April 1989, or
another method approved by MDEQ.

(4) Site-Specific Variables - If the Applicant can demonstrate to the

satisfaction of MDEQ that site-specific variables (i.e., exposure duration,
exposure frequency, moisture content, etc.) are more representative of site
conditions than the default variables utilized in the development of the Tier 1
TRGs, the Applicant may modify site-specific variables in the risk calculation
to develop RGs for the CoCs. Chemical-specific values (i.e., Henry's law
constant, diffusivity in water, etc.) must be taken from EPA's Soil Screening
Guidance: Technical Background Document (EPA/540/R-95/128), May
1996, unless otherwise approved by MDEQ. The Applicant shall not adjust
the following variables in the development of site-specific RGs in Tier 2:

i.

Oral cancer slope factor;

ii.

Inhalation cancer slope factor;

iii.

Oral chronic reference dose;

iv.

Inhalation chronic reference dose;

v.

Target excess individual lifetime cancer risk;

vi.

Target hazard index;

vii.

Body weight, adult; or

viii.

Body weight, child.

(5)	Eliminate/Minimize Exposure Routes - If the Applicant can demonstrate to the
satisfaction of MDEQ that land-use restrictions and engineering controls at the
site will eliminate all complete exposure pathways or will minimize
contamination exposure to levels that will be protective of human health and the
environment, MDEQ may determine that further remediation is not required.
The Commission considers the presence of free product to be an unacceptable
potential risk to public health and the environment because it is considered to
be a continuing source of contamination that may increase the level of risk that
is the basis for the remediation requirements, may reduce the margin of safety
provided by the remediation design, or may jeopardize the permanence of the
Brownfield Agreement. Therefore, free product must be removed unless it can
be demonstrated to the satisfaction of MDEQ that removal of the free product is
technically impracticable. The Applicant must also demonstrate to the
satisfaction of MDEQ that the contamination is confined and will remain
confined within the site boundaries. Any monitoring plan must be approved by
MDEQ.

(6)	TPH Fractioning - In areas where concentrations of Tier 1 petroleum
hydrocarbon indicator compounds are not quantifiable to the Tier 1 TRGs and
where the concentrations of TPH exceed the Tier 1 TRG for TPH-GRO/DRO,
the Brownfield Applicant may either (1) conduct a more detailed evaluation of
petroleum hydrocarbons using the methodology outlined in Chapter 7 of this

14


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

Subpart II or (2) conduct an evaluation of TPH utilizing another methodology
approved by MDEQ.

(7) Other Approved Methods - MDEQ may approve other risk evaluation
methodologies or combinations thereof under Tier 2.

(b)	MDEQ may consider utilizing the Method Detection Limit (MDL) as the site-specific
Remediation Goal (RG) on a case by case basis.

(c)	References for any fate and transport models used for the exposure point
calculations (EPA-approved model or models that have been peer reviewed by
experts in the modeling field) and all input values and assumptions for the models
must be provided to and approved by MDEQ.

Chapter 5. TIER 3 EVALUATION

Section 501. Tier 3 Evaluation Target Risk Level

(a) Human Health

(1)	The remediation goal (RG) for each individual contaminant which is a
carcinogen must be calculated to attain a Risk Level of 10"6 (i.e., 1 in a million) or
which is a systemic toxicant must be calculated to attain a total hazard quotient
of not more than 1, except with regard to a background chemical concentration
or a regionally prevalent chemical concentration. In cases where contaminants
with corrective action concentrations established through federal and/or state
programs (i.e., Safe Drinking Water Act maximum contaminant levels (MCLs))
are present, the MDEQ will determine the appropriate corrective action
concentration on a contaminant by contaminant basis. In no event, except with
regard to a background chemical concentration, may either (1) the cumulative
(total) site carcinogenic risk exceed 1 x 10"4 for carcinogenic CoCs or (2) the site
hazard index (summation of hazard quotients) exceed 3 for non-carcinogenic
CoCs affecting the same organ or organ system.

(2)	The MDEQ may consider an alternative quantitative or qualitative remediation
goal (RG) for each individual contaminant, provided the Applicant can
demonstrate to the satisfaction of MDEQ that the attainment of (1) a Risk Level
of 10"6 for each individual carcinogenic contaminant or (2) a total hazard
quotient of not more than 1 for each individual systemic toxicant is technically
impracticable, except with regard to a background chemical concentration or a
regionally prevalent chemical concentration.

(3)	The Site risk levels shall be based on high-end exposure (use of high-end
values for the exposure point concentration and exposure duration parameters)
in the intake calculation of a deterministic risk assessment or 90th percentile of
the risk presented in the probabilistic risk assessment. The Site hazard indices

15


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

and/or quotients shall be based on high-end exposure in a deterministic risk
assessment or 90th percentile of the exposure presented in the probabilistic risk
assessment.

(b) Ecological

(1) For a Tier 3 Ecological Evaluation, one of the following must be satisfied:

i.	High-end CoC concentrations in the impacted media must be below their
respective threshold concentrations or regulatory values that are protective
of the ecological receptors of concern or the valued resources to be
protected;

ii.	Findings from a field survey indicate that there is no readily apparent harm at
the site or notable difference (at 95% confidence level) between the site and
the potentially impacted ecological receptors;

iii.	Individual hazard quotients estimated for the ecological receptors of
concern, valued natural resources, or their surrogate species are below unity
(1) for each CoC; or

iv.	Additional ecological risk evaluations performed under the MDEQ approved
work plan conclude that the potential ecological risk is insignificant or readily
recoverable.

Section 502. Tier 3 Evaluation (Risk Assessment) Procedures

(a)	The Applicant may choose to conduct a site-specific risk assessment (Tier 3),
develop and meet site-specific RGs, and have the site-specific RGs approved by
MDEQ. This Tier 3 option may entail additional costs to the applicant for MDEQ to
subcontract the review of the toxicological and/or risk assessment evaluation.

These additional costs shall be paid by the Applicant.

(b)	For a human health evaluation of the site or areas within the site (if the site
characterization data support such area delineations), the Applicant shall perform
risk characterization and present information on risk assessment uncertainty in
accordance with the following options:

(1)	Deterministic risk assessment according to RAGS - Part A methodology (high-
end risk and hazard).

(2)	Deterministic risk assessment according to RAGS - Part A (high-end and
average risk and hazard).

(3)	Probabilistic risk assessment according to EPA's Guiding Principles for Monte
Carlo Analysis (EPA/630/R-97/001) or RAGS - Part E methodology to provide
probability density function [PDF] for identifying mean, median, and 90th
percentile risk and hazard.

16


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

(4) Population cancer risk characterization based on the product of average site
carcinogenic risk for an individual and the projected number of exposed
individuals. Population non-cancer hazard characterization will be based on the
projected number of individuals who are likely to be exposed resulting in the
hazard index for each specified systemic effect exceeding one (1).

(c)	The human health evaluation report shall include, at a minimum, four components:
hazard identification, toxicity assessment, exposure assessment, and
characterization of risk and uncertainty.

(1)	Hazard identification - This component presents the site history, area(s) where
releases have occurred, and the identified site-related chemicals (i.e., CoCs).
Site data shall be compiled at the 95% UCL of the mean and compared with the
95% UCL of the mean background data to establish whether the concentration
for a detected chemical is above or below background level.

(2)	Toxicity assessment - This component requires the identification of CoCs as
carcinogenic, non-carcinogenic (causing systemic effects), or both. Toxicity
values used in the risk assessment are slope factors and reference doses and
must be obtained from:

i.	EPA's Integrated Risk Information System (IRIS),

ii.	Health Effects and Assessment Summary Tables (HEAST),

iii.	Toxicological Profiles prepared by the Agency for Toxic Substances
and Disease Registry (ATSDR), and

iv.	other peer-reviewed reference sources or literature approved by
MDEQ.

(3)	Exposure Assessment - This component estimates the type and magnitude of
exposures to the CoCs that are present at or migrating from the Site. The
results of the exposure assessment are combined with chemical-specific toxicity
information to characterize potential risks. The general procedure for
conducting an exposure assessment is outlined in Chapter 6 of RAGS.

(4)	Characterization of Risk and Uncertainty - This section describes the final
step of the health risk assessment process. In this step, the toxicity and
exposure assessments are summarized and integrated into quantitative and
qualitative expressions of risk. Major assumptions, scientific judgments, and, to
the extent possible, estimates of the uncertainties embodied in the assessment
are also presented.

(d)	Non-carcinogens that act on the same organ systems can be identified in Table 2,
EPA's Soil Screening Guidance: Technical Background Document (EPA/540/R-
95/128) or Appendix A, Tables E, Title 35 Illinois Administrative Code Part 742, as
amended. The Applicant must identify the uncertainty associated with each toxicity

17


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

value. Toxicity values with a high degree of uncertainty should not be used in the
risk assessment.

(e)	The Applicant shall provide information on the CoC exposure point concentrations
(EPCs), activities, and exposure routes that lead to exposure. Site-specific
information in combination with relevant information found in EPA's Exposure
Factors Handbook (Volumes I, II, and III, EPA's National Center for Environmental
Assessment, March 1998), AlHC's Exposure Factors Sourcebook, or other peer-
reviewed literature approved by MDEQ may be used to assess exposure. At a
minimum, the exposure assessment shall include:

(1)	a SCEM to provide the basis for determining which exposure pathways are
complete; and

(2)	specific input values and their basis (references) for exposure parameters such
as the exposure frequency (days per year), duration (number of years), and
absorption factors.

(f)	Carcinogenic risk and non-carcinogenic hazard posed by the CoCs shall be
estimated for the Site or areas within the Site where past releases have occurred.
Risks from all complete exposure pathways (i.e., incidental ingestion, dermal
contact, inhalation of volatiles or particulates), and contaminated on-site food
sources (indirect exposure) shall be characterized, as identified in the SCEM.

(1)	Carcinogenic risks from individual CoCs for all complete exposure pathways
shall be summed to provide the total site carcinogenic risk (cumulative excess
lifetime cancer risk to an individual).

(2)	Non-carcinogenic hazards (hazard quotients) from individual CoCs that act on
the same organ or organ system for all complete exposure pathways shall be
summed to provide the site hazard indices.

(g)	The following risk assessment protocols shall be followed for assessing special
chemicals or categories of chemicals, unless otherwise approved by MDEQ:

(1)	Chlorinated dioxins and dibenzofurans - The evaluation of chlorinated
dioxins and dibenzofurans must be consistent with EPA Region IV's Human
Health Risk Assessment Bulletins: Supplement to RAGS

(http://www.epa.gov/region04/waste/ots/healtbul.htm).

(2)	Lead and lead-based compounds - For the assessment of risk to children (if
such receptors are reasonably anticipated to be present under the current
and future use scenarios), the EPA's Integrated Exposure Uptake Biokinetic
Model (IEUBK) (EPA/540/R-93/081) shall be used. If adults are the
receptors, the Adult Lead Model published in the "Recommendations of the
Technical Review Workgroup for Lead for an Interim Approach to Assessing
Risks Associated with Adult Exposures to Lead in Soil" (December 1996) by

18


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

the EPA Technical Review Workgroup (TRW) shall be used to assess the
hazard of lead exposure.

(3)	Polycyclic aromatic hydrocarbons (PAHs) - The evaluation of PAHs must be
consistent with EPA Region IV's Human Health Risk Assessment Bulletins:
Supplement to RAGS

(http://www.epa.qov/reqion04/waste/ots/healtbul.htm).

(4)	Polychlorinated biphenyls (PCBs) - A slope factor of 7.7 (mg/kg/day)"1 shall
be used for total PCBs. If congener-specific or group-specific (mono-
through deca-chlorinated) biphenyls are analyzed and quantified using
Modified EPA Method 1668, the slope factor to be used will be 2.0
(mg/kg/day)"1 for tri-, tetra-, penta-, hexa-, and hepta-chlorinated PCBs.

Slope factors lower than 2.0 (mg/kg/day)"1 may be used if there are low
concentrations of 2,3,7,8-substituted PCBs). The lowest slope factor of 0.4
(mg/kg/day)"1 can be used if 2,3,7,8-substituted PCBs are not present. The
Applicant shall bear the burden of providing documentation to MDEQ to
justify using slope factors lower than 7.7 (mg/kg/day)"1 in the risk
assessment report.

(5)	Radioactive materials or radionuclides - The risk assessment of radioactive
materials shall be in accordance with Chapter 10 of RAGS - Part A. Other
methodologies (e.g., dose reconstruction for exposure assessment) shall be
approved by MDEQ on a case-by-case basis.

Section 503. Tier 3 Ecological Risk Evaluation Procedures

(a) For the entire Site or areas within the Site (if the site physical characteristics

support delineations of different ecosystems), the Applicant shall perform screening
and/or more in-depth ecological risk evaluations and present uncertainty associated
with the evaluations in accordance with the following options:

(1)	Identify the ecological receptors of concern and compare CoC concentrations in
the potentially impacted media with their respective benchmark or threshold
values that are protective of the receptors of ecological concern. The initial
screening levels and procedures are available in the EPA Region 4 Ecological
Risk Assessment Bulletins- Supplement to RAGS

(http://www.epa.qov/reqion04/waste/ots/ecolbul.htm).

(2)	Additional ecological benchmark values are available from EPA (e.g., Office of
Technical Services Supplemental Guidance to RAGs: Region IV), U.S. Fish and
Wildlife Service, the National Atmospheric and Oceanic Administration, or other
values in peer-reviewed literature, as appropriate.

19


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

(3)	Conduct biological field surveys for species diversity and abundance in the
potentially impacted area and a reference (background) area and compare both
survey results to determine whether there are significant differences at 95%
level of confidence.

(4)	Identify assessment and measurement endpoints and perform a deterministic
risk evaluation on the receptors of ecological concern or their indicator species
by the hazard quotient method.

(5)	Perform additional ecological risk evaluations based on an MDEQ-approved
work plan submitted by the Applicant that is consistent with the EPA's
Framework for Ecological Risk Assessment guidance and its subsequent
update.

(b) A deterministic risk evaluation shall include a minimum of four components:

problem formulation, ecological effects assessment, exposure assessment, and

characterization of risk and uncertainty.

(1)	Problem formulation - This component presents the site history (including
documented incidents of readily apparent harm), physical characteristics,
area(s) where releases have occurred, and identified site-related chemicals
(i.e., CoCs). This component also proposes and provides the rationale for
identifying any ecological receptors of concern and valued resources present on
site that may be impacted by the CoCs. The basis for assessment and
measurement endpoint(s) selection should be provided to MDEQ.

(2)	Ecological effects assessment - This component requires the identification of
potential or known acute and chronic toxic effects of the CoCs on the ecological
receptors of concern, valued resources, and any surrogate species proposed as
the measurement endpoints. Dose-response data shall be obtained from EPA
data bases or other federal/state databases approved by MDEQ.

(3)	Exposure assessment - This component presents the SCEM and explains
how the CoCs are released, transported, bioconcentrated or biomagnified in
organisms, and exposed to the ecological receptors of concern or valued
resources to be protected. Where appropriate, behavior patterns or reasonable
assumptions should be used to estimate daily intake of the CoCs.

(4)	Characterization of risk and uncertainty - This component shall present the
risk assessment results and the underlying uncertainty associated with the
assessment method employed. If a quotient method is used, the hazard
quotients shall be estimated for the ecological receptors of concern or their
surrogates. Risk may be characterized qualitatively by the weight-of-evidence
approach based on professional judgment. This component should identify
types and magnitude of potential effects anticipated, the spatial and temporal

20


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

extent of the effects, significance of the effects on the ecosystems, and recovery
potential.

(c) A Tier 3 ecological risk evaluation shall be presented in the following report format:
problem formulation, approach and rationale, and presentation of results,
uncertainties, and recommendations. In interpreting these evaluation findings, the
Applicant should consider the effects of natural succession, non-site related
impacts (e.g., farm or urban runoff), and seasonal changes on the data or
observations collected. The report format may vary based on MDEQ requirements
of the ecological risk evaluation work plan.

Section 504. Tier 3 Risk Assessment Data Requirements

(a) The basic procedure for the assessment of human health and ecological receptors
of concern for a Tier 3 risk assessment shall be to obtain representative site
characterization data in order to perform a screening or more in-depth risk
assessment. Specific requirements for performing a Tier 3 risk assessment
include, but are not limited to, the following:

(1) Site characterization data shall be obtained in accordance with the MDEQ-
approved Quality Assurance Project Plan (QAPP). The Applicant must
demonstrate that the Site has been adequately characterized to delineate the
nature and extent of contamination. The scope of the site investigation shall be
based on the considerations set forth below.

i.	Previous field investigations should be used to define the SCEM and
identify data gaps or uncertainty for the nature and extent of the site
characterization under this site investigation phase.

ii.	Field analytical data may be used to identify areas of contamination and
to supplement fixed-laboratory analyses if the Applicant can demonstrate
that the field analytical data are comparable to fixed laboratory data by
regression or co-relational analyses and meet DQO requirements for
precision, accuracy, and reproducibility. A minimum of 10% of the
collected samples shall be fixed-laboratory data to demonstrate
correlation. Samples must be collected from the areas exhibiting the
highest field concentrations and analyzed at a fixed laboratory.

iii.	Areas with distinct high concentrations of site-related chemicals shall be
segregated from other areas for data compilation purposes. Additional
field characterization of high-concentration areas or areas with buried
wastes is necessary to support remedial design.

iv.	The RAGS procedure for the selection of CoCs shall be followed to
properly characterize the Site. The Applicant should exclude background

21


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

chemicals, laboratory and field contaminants or artifacts, and chemicals
that are essential nutrients present at or below the recommended daily
allowance intake levels.

v. All reported data shall be in compliance with the DQOs established in the
QAPP. In addition to data review, the data will be validated by a qualified
technical individual, familiar with data validation, at the rate of at least
10% or as otherwise specified by MDEQ. The Applicant shall provide
data review and validation summaries in the Site Characterization
Report.

Chapter 6. RISK-BASED REMEDIATION
Section 601. Risk-Based Remediation Goals

(a)	Risk-based remediation goals (RGs) may be quantitative for chemical-specific RGs
or qualitative for remedial action-specific RGs. The methodology for quantifying the
chemical-specific RGs involves solving for the concentration term given a defined
risk level in a deterministic or probabilistic risk assessment and shall be proposed
for the principal threat chemicals or all CoCs if the principal threat chemicals cannot
be identified. The chemical-specific RG may be modified upward or downward
based on risk management considerations by MDEQ. A qualitative RG is
established by describing the objectives for engineering controls that reduce site
risk to an acceptable level. Risk-based remediation goals shall accompany the
proposed remedial action(s) in the Site Characterization Report and/or the
Corrective Action Plan (CAP).

(b)	Quantitative RG - Site-specific information that is relevant to the future use of the
Site shall be used in the risk methodology.

(1) The derived value shall not be higher than the soil saturation limit (Csat) for the
soil or sediment RG for a CoC with a melting point less than 30 degrees
Celsius. The derived value shall not be higher than the solubility limit (Csol) for
the groundwater RG for groundwater. At sites where a mixture of contaminants
is present (e.g., gasoline), the effective solubility limit may be used if required by
MDEQ. Values for Csat and Csol may be found or derived from equations in
EPA's Soil Screening Guidance: Technical Background Document (EPA/540/R-
95/128), May 1996 or other reference approved by MDEQ.

(2) The derived chemical-specific RG for a carcinogen for the protection of human
health shall be (1) the MCL value, (2) a value derived using the acceptable
carcinogenic risk level of 1 x 10"6, or (3) a value defined in state/federal
programs and approved by MDEQ.

(3) The derived chemical-specific RG for a non-carcinogen for the protection of
human health shall be (1) the MCL value, (2) a value derived using the

22


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

acceptable hazard quotient level of unity (1), or a value defined in state/federal
programs and approved by MDEQ.

(4)	The MDEQ may consider an alternative quantitative or qualitative remediation
goal (RG) for each individual contaminant, provided the Applicant can
demonstrate to the satisfaction of MDEQ that the attainment of (1) a Risk Level
of 10"6 for each individual carcinogenic contaminant or (2) a total hazard
quotient of not more than 1 for each individual systemic toxicant is technically
impracticable except with regard to a background chemical concentration or a
regionally prevalent chemical. In no event, except with regard to a background
chemical concentration, may either (1) the cumulative (total) site carcinogenic
risk exceed 1 x 10"4 for carcinogenic CoCs or (2) the site hazard index
(summation of hazard quotients) exceed 3 for non-carcinogenic CoCs affecting
the same organ or organ system.

(5)	Any of the following methods may be used to derive chemical-specific
quantitative RGs in soil or sediment to protect human health:

i.	algorithms or methodology employed by MDEQ in deriving the TRGs in
Appendix A of this Subpart II;

ii.	algorithms or methodology employed by EPA Region III (Technical and
Program Support Branch, 3HW70) to derive the Risk-Based Concentrations
(RBCs);

iii.	algorithms or methodology employed by EPA (Office of Solid Waste and
Emergency Response) to derive the SSLs using EPA's Soil Screening
Guidance: Technical Background Document (EPA/540/R-95/128), May
1996;

iv.	algorithms or methodology employed by the American Society of Testing
and Materials (ASTM) to derive the Risk-Based Screening Levels (RBSLs)
(Emergency Standard Guide ES 38-94); or

v.	other EPA published or peer-reviewed methodologies that have been
reviewed and approved by MDEQ.

Note: All input/default values must be approved by MDEQ prior to employing any

of the above methodologies.

(6)	Fate and transport modeling and/or the use of a dilution-attenuation factor
(DAF) to determine migration-to-groundwater soil RGs approved by MDEQ may
be used to demonstrate that the concentrations of CoCs at the source area
provide adequate protection of human health and the environment at the Site
boundary, except when it appears that free product is present.

23


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

(7)	The acceptable level of a CoC in groundwater at the Site boundary is its
groundwater RG or if the boundary is a surface water body, the water quality
criteria published by MDEQ, whichever is lower.

(8)	Any of the following methods may be used to derive chemical-specific
quantitative RGs in groundwater:

i.	algorithms or methodology employed by MDEQ in deriving the TRGs in
Appendix A of this Subpart II;

ii.	algorithms or methodology employed by EPA Region IX (Technical Support
Team, DFD-8-B) to derive the Preliminary Remediation Goals (PRGs); or

iii.	other EPA published or peer-reviewed methodologies that have been
reviewed and approved by MDEQ.

(9)	The quotient method may be used to derive quantitative RGs for the protection
of an ecological receptor of concern.

(10) The following methods may be used to derive chemical-specific quantitative
RGs in soil and sediment for protection of an ecological receptor of concern:

i.	algorithms or methodology described in the Risk Assessment Handbook,
Volume 2 - Environmental Evaluation (EM 200-1-4) developed by the U.S.
Army Corps of Engineers; or

ii.	other EPA published or peer-reviewed methodologies that have been
reviewed and approved by MDEQ.

(c) Qualitative RG - A qualitative RG shall define objectives and describe how land-
use restrictions and/or engineering controls are expected to reduce site risk to an
acceptable level. The following information shall be presented:

(1)	complete exposure pathway that contribute to human health or environmental
risk;

(2)	the CoC or principal threat chemical and its background concentrations;

(3)	physical, chemical, and fate and transport properties of the CoC or principal
threat chemical (including the potential for adsorption and monitored natural
attenuation);

(4)	presence of any man-made or natural conveyances, conduits, or transport
routes from the source to the receptor location;

24


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

(5) Potential engineering controls that will exclude the exposure pathway based on
treatability study data and/or practical experience may also be considered.
Engineering controls may include physical or hydraulic control measures, but
shall not include the exclusive use of security fencing. Typical engineering
controls are presented below and the Applicant may propose alternative
controls for MDEQ approval.

i.	groundwater recovery trenches and leachate collection systems;

ii.	groundwater extraction (pumpage) and treatment systems;

iii.	engineered caps with or without liner systems;

iv.	slurry walls, funnel-and-gate barrier walls, bio-polymer walls, or any
modifications thereof; and

v.	permanent structures such as building, driveways, and paved roads.

(d) No further action at the Site shall be based on obtaining either the quantitative or
qualitative RGs, or both, and/or other terms and conditions stipulated by MDEQ
(i.e., Brownfield Agreement, Corrective Action Plan). The Applicant has the option
to propose either type of RGs or a combination of the two for delineated areas of
the Site, depending on the site-specific factors, chemical data, and risk
management considerations approved by the MDEQ. The following criteria shall
be met for this determination:

(1)	The remedial action has achieved the chemical-specific RGs based on
verification sampling and analyses at the point of exposure or at the
contaminated source area. The 95% UCL of the normalized verification sample
data must be less that the chemical-specific RG.

(2)	The engineered control measures proposed by the Applicant and approved by
MDEQ are completed.

(3)	The groundwater quality at the Site boundary shall not exceed MCLs or risk-
based TRGs for groundwater identified in Appendix A. The Point of Compliance
is the Site Boundary.

(4)	Free product must be removed from the Site, unless it can be demonstrated to
the satisfaction of MDEQ that removal of the free product is technically
impracticable and that the contamination is confined and will remain confined
within the Site boundaries. Free product is considered to exist if:

i.	concentrations in soil exceed Csat for CoCs with a melting point of less than
30 degrees Celsius;

ii.	concentrations in groundwater exceed Csol for any CoC or the effective Csol
or

iii.	measurable using best available technologies.

Chapter 7. PETROLEUM HYDROCARBONS
Section 701. Introduction

(a)	Specific procedures and evaluation criteria have been developed for sites with
petroleum hydrocarbon contamination. This criteria has been developed to simplify
the contaminant analyses required to characterize the site and to establish site-
specific remediation goals (RGs). Petroleum hydrocarbon indicator compounds
(i.e., Benzene, Toluene, PAHs, etc.) may not be quantifiable at the Tier 1 TRG
Table concentrations because high petroleum hydrocarbon concentrations in the
sample may cause analytical interferences resulting in either of the following:

(1)	Dilution of the extract, which would cause elevated detection limits and useless
surrogate recovery data; and/or

(2)	Inaccurate compound identification and quantification, due to a poor peak
separation or an elevated baseline during chromatography.

(b)	In addition, of the 250 individual compounds identified in petroleum, only 95 have
toxicity data. Of these 95 compounds with toxicity data, only 25 have sufficient
data to develop toxicity criteria. The interactive effects of all compounds present in
TPH cannot be determined by data on 25 individual compounds. Therefore, to
account for these unknowns, as well as to account for instances as described in
Section 701(a), these procedures have been developed.

(c)	To evaluate human health and environmental risks specific to a Site under the
circumstances in Section 701(a)(1) and (2), MDEQ has developed procedures for
petroleum hydrocarbon contaminated Sites.

Section 702. Petroleum Hydrocarbon Evaluation Procedures

(a)	The Applicant shall utilize the procedures presented herein for the evaluation of
potential human health and environmental risks from petroleum hydrocarbons in
soil and groundwater.

(b)	A Tier 1 Evaluation of indicator compounds of petroleum hydrocarbons and TPH is
required to establish the vertical and horizontal extent of indicator compound
concentrations and TPH below the unrestricted values of the Tier 1 TRG Table.

(c)	A Site Ecological Checklist must be completed.

(d)	Petroleum-impacted soil and groundwater shall be assessed using the petroleum
hydrocarbon indicator compounds, TPH-GRO, and TPH-DRO as presented in
Appendix B, Table 1. Petroleum hydrocarbon categories presented in Appendix B,
Table 1 represent typical hydrocarbon products. The Applicant shall correlate the

26


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

site-specific hydrocarbon release and/or knowledge of the released hydrocarbon
product to the appropriate category listed in Appendix B, Table 1. If the specific
product that has been released is unknown, then a complete analytical evaluation
must be conducted.

(e)	The Applicant shall perform soil and groundwater laboratory testing for the following
indicator compounds:

(1)	Volatile Organic Compounds, including MTBE by SW-846 Method 8260B, or
other Method approved by MDEQ.1

(2)	Polycyclic Aromatic Hydrocarbons (PAHs) by Method 8310, with appropriate
sample extraction, clean-up and instrumental finish. Analysis to be conducted
for the PAHs listed in Appendix B, Table 1, or other Method approved by
MDEQ.

(3)	Metals2 by SW-846 Method 6010, 6020, or the appropriate 7000 series, or other
Method approved by MDEQ.

(4)	Methyl ethyl ketone2 by SW-846 Method 8260B, or other Method approved by
MDEQ.

(5)	Methyl isobutyl ketone2 by SW-846 Method 8260B, or other Method approved
by MDEQ.

Note:	1 All soil samples collected for VOC analysis must be collected in a manner consistent with MDEQ's

Guidance for Collecting Volatile Organic Compounds in Soil, unless otherwise approved by MDEQ.
2 When suspected to be present

(f)	Although lead (organic and inorganic) has not been used as a gasoline additive for
some time (since the late 1970's to early 1980's), there may be sites where lead
(organic and inorganic) may be present due to historical activities on the Site. At
sites where lead is suspected to be present as a potential site-related compound,
inorganic lead and organic lead (specifically tetraethyl lead) must be identified as
target analytes by appropriate analytical methods approved by MDEQ.

Section 703. Tier 1 Petroleum Hydrocarbon Evaluation

(a)	A Tier 1 Evaluation of indicator compounds of petroleum hydrocarbons, TPH-GRO,
and TPH-DRO is required to establish the extent of indicator compound
concentrations and TPH-GRO/DRO below the Tier 1 TRG Table.

(b)	Results of the indicator compound analysis, TPH-GRO, and TPH-DRO shall be
compared with the TRGs presented in the Tier 1 TRG Table in Appendix A utilizing
the Tier 1 Evaluation Procedures outlined in Section 302 of this Subpart II.

27


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

(c)	The Applicant shall address a hydrocarbon release using TPH analyses using SW-
846 Method 8015B or other Method approved by MDEQ and by analyzing the
indicator compounds as described in Section 701.

(d)	In areas of the site where the indicator compounds cannot be quantified to the Tier
1 Target Remedial Goal concentrations, the Applicant has the option of either:

(1)	conducting a Tier 1 Evaluation utilizing the Tier 1 Evaluation Procedures
outlined in Section 302 of this Subpart II for TPH-GRO and TPH-DRO;

(2)	conducting a Tier 2 Evaluation using TPH Fractioning; or

(3)	conducting a Tier 3 Evaluation using methods approved by MDEQ.

Section 704. Tier 2 Petroleum Hydrocarbon Evaluation - TPH Fractioning

(a)	A Tier 2 Petroleum Hydrocarbon Evaluation is primarily utilized in cases as
described in Section 701 of this Subpart II where indicator compound
concentrations cannot be determined due to dilution and interference and where
the concentrations of TPH-GRO/DRO exceed the restricted Tier 1 TRG levels for
TPH-GRO/DRO. Along with the required comparison of indicator compounds as
described in Section 703(b) of this Subpart II, the Applicant shall have the option of
utilizing the TPH Carbon Fraction TRGs in Table 2 of Appendix B.

(b)	Massachusetts Method

(1)	The Massachusetts Department of Environmental Protection (MADEP)
VPH/EPH Approach may be utilized to evaluate petroleum hydrocarbons under
Tier 2. This method quantifies the total petroleum hydrocarbon fractions into
collective aliphatic and aromatic ranges. To account for the hydrocarbon
ranges present in contaminated media, MADEP's Volatile Petroleum
Hydrocarbon (VPH) method and Extractible Petroleum Hydrocarbon (EPH)
method have been developed. A detailed description of the MADEP VPH/EPH
Approach may be found on the MADEP Web Site at

(http://www.state.ma.us/dep/bwsc/vph eph.htm).

(2)	The following principles form the basis for this approach:

i.	Petroleum products are comprised mainly of aliphatic/alicyclic and aromatic
hydrocarbon compounds.

ii.	Aromatic hydrocarbons appear to be more toxic than aliphatic compounds.

iii.	The toxicity of aliphatic compounds appear to be related to their carbon
number/molecular weight.

28


-------
Final Brownfield Regulations
Subpart II
February 28, 2002

(3) Under this approach, the non-cancer toxicity of petroleum contaminated soil or
water has been established by (1) determining the collective concentrations of
specified ranges of aliphatic and aromatic hydrocarbons, and (2) assigning a
toxicity value to each range. Well-characterized compounds within specified
ranges have been selected as "surrogate" indicators to define the toxicity of the
entire range.

(4)	Carcinogenic and additional non-carcinogenic effects must be evaluated for
the indicator constituents listed in Table 1 of Appendix B.

(5)	The EPH method separates the TPH Carbon Ranges (Fractions) into 3 sub-
fractions and indicator PAH compounds. The VPH method separates the
GRO Carbon Ranges (Fractions) into 3 sub-fractions and indicator
compounds (i.e., BTEX, MTBE and naphthalene).

(6)	The VPH Method is a Purge and Trap, GC/PID/FID procedure and the EPH
Method is a solvent extraction/fractionation GC/FID procedure.

(7)	The unrestricted TRGs listed in Table 2 of Appendix B have been adopted
by MDEQ and correlate with the GW-1 groundwater zone the S-1 soil zone
as defined by MADEP.

(8)	The restricted TRGs listed in Table 2 of Appendix B have been adopted by
MDEQ and correlate to the GW-1 groundwater zone and the S-3 soil zone
as defined by MADEP.

(9)	The Applicant must ensure and provide documentation to MDEQ that the
Laboratory conducting the MADEP VPH/EPH Methodology is equipped to so

29


-------

February 28, 2002

do and will utilize appropriate Standard Operating Procedures (SOPs) as
required by this methodology.

(c) MDEQ may approve other TPH risk evaluation methodologies (e.g., TPHWG
Methodology) or combinations thereof under Tier 2.

Section 705. Tier 3 Petroleum Hydrocarbon Evaluation

(a) Alternative petroleum hydrocarbon Remedial Goals (RGs) may be established
using a Tier 3 Risk Assessment approach. The alternative RGs shall be reviewed
and approved or disapproved by MDEQ on a case-by-case basis.

of controls.

! Reduction of Mobility, Toxicity, or Volume: Degree to which CoCs in
source zone media are irreversibly destroyed, converted to a non-toxic state,
or immobilized.

! Near-Term Effectiveness: Control of workers and community
exposure/safety and environmental impacts duirng period of remedy
installation or implementation; time period required to achieve corrective
action objectives.

! Implementability: Ability to construct, operate, and monitor the performance
of the remedial option; associated permitting requirements; availability of
required equipment and services.

! Cost Efficiency: Life-cycle capital and operating costs relative to degree of
risk reduction achieved.

Page 8 of 14


-------
The evaluation should include remedial options that would meet Tier 1 Unrestricted
and Restricted TRGs, and the Tier 2 Remediation Goals (RGs), when appropriate.
Utilize the BASELINE SCEM to define the proposed remedial action in terms of the
targeted exposure points and the remedial options to be applied. Remedial options
may include, where appropriate, deed restrictions and engineering controls.

9.2	Describe the remedial option that has been selected and the rationale for its
selection. Complete the REMEDIAL SCEM and describe the actions that will be
taken to minimize and/or eliminate risk to the public health and the environment.

MISSISSIPPI DEPARTMENT OF ENVIRONMENTAL QUALITY
BROWN FIELDS CORRECTIVE ACTION PLAN FORMAT

General: This guidance presents the recommended content and format for the Brownfield
Corrective Action Plan. Please note that this guidance is comprehensive and does not
segregate report content or format based on the varied media impacted. Also note
that many of the content items are common for all impacted media. The primary difference
is whether the contaminated media are soil, sediment, surface water or groundwater only
or a combination thereof and whether contamination is on or off site. This format is
designed to advise a person, prior to submitting an application, of the information
necessary to achieve the adequate and cost-effective remediation of a Site. The guidance
should be used and adapted as appropriate for the specific property being addressed.
Strict adherence to this format and inclusion of the suggested contents will lessen the
overall review time needed by the Mississippi Department of Environmental Quality
(MDEQ) staff.

-------
SECTIONS

1.0	Introduction

1.1	Objectives/Rationale

Provide a general overview of the objectives and rationale for the Corrective Action
Plan.

2.0 Conceptual Design

Present the conceptual design and identify the design elements (i.e., extraction
flowrate, discharge limitations, radius of influence, limits of excavation, elimination
of exposure routes, etc.). The conceptual flow design should be described and a
schematic of the system should be presented. Include the acceptable ranges for
the design elements, if applicable. Based on conclusions from Section 8.2 of the
Site Characterization Report, prepare a detailed description of proposed remedial
activities and describe how corrective actions will eliminate or reduce risk to human
health and the environment. Remedial actions may include, where appropriate,
deed restrictions and engineering controls.

3.0 System Components

Identify the system components (i.e., extraction well orientation, placement, and
construction; manifold piping; vapor treatment equipment; instrumentation &
controls, etc.) and design criteria.

4.0 Schedule

Prepare a detailed schedule for initiation and completion of all remedial actions.

5.0 Remedial Goals (RGs)

Describe the Remedial Goals (RGs) and how they will be met and measured.

6.0 Operation and Monitoring (O&M) Plan

Include a system operation and monitoring plan for both the system start-up phase
and for long-term operations.

Page 2 of 3


-------
7.0 Performance Monitoring Plan

Include a performance monitoring plan that will be utilized to evaluate the
effectiveness of the remedial action, particularly for active remedial options such as
the installation of a pump and treat system. The performance monitoring program
must include a list of indicators (i.e., hydraulic head monitoring for containment in
a pump and treat system, etc.), and an acceptable range of values for each
indicator. Include any verification sampling methodologies, procedures, frequency,
number of parameters and Quality Assurance/Quality Control(QA/QC)
considerations.

8.0 Compliance Monitoring Plan

Prepare a Compliance Monitoring Plan that addresses groundwater monitoring to
ensure that the contamination has stabilized and/or will not migrate off-site.
Typically, groundwater monitoring must begin with quarterly sampling for two years
to account for seasonality and to provide enough data points to determine whether
statistically significant trends are present. Proposals for a reduction in frequency
of monitoring after the initial two years may be presented and approved on a site-
specific basis.

9.0 Contingency Plan

Prepare a contingency plan that will be implemented should the proposed
Corrective Action Plan not meet its goals. A set of performance measures should
be proposed that would be utilized to "trigger" the implementation of the contingency
plan. For example, Monitored Natural Attenuation is proposed, and downgradient
sentinel wells currently exhibit non-detectable concentrations of a contaminant.
The "trigger" would be to activate the contingency plan should a sentinel well reach
a concentration of 0.005 mg/L of the contaminant. A schedule for implementing the
contingency plan must be included. A contingency plan that does not adequately
address potential site contaminant exposure scenarios, may require the Brownfield
Party to modify the Brownfield Agreement.

Section 4 - Criteria for Further Assessment

If the Area of Impact (AOI) meets all of the criteria presented below, then typically no further
ecological evaluation shall be required. If the AOI does not meet all of the criteria, then a screening
level ecological risk shall be conducted. The Submitter should make the initial decision regarding
whether or not a screening level ecological risk assessment is warranted based on compliance of the
AOI with criteria listed below. After review of the ecological checklist and other available site
information, the Mississippi Department of Environmental Quality will make a final determination on
the need for a screening level ecological risk assessment. If site conditions at the AOI change such
that one or more of the criteria are not met, then a screening level ecological risk assessment shall
be conducted.

The criteria for exclusion from further ecological assessment include:

The area of impacted soil is approximately 1 acre or less in size;

There is no current (or potential) release (via runoff or groundwater discharge) of COCs from
the AOI to a surface water body;

Recreational species, commercial species, threatened or endangered species, and/or their
habitats are not currently being exposed, or expected to be exposed, to COCs present at or
migrating from the AOI; and

There are no obvious impacts to ecological receptors or their habitats.

Section 5 - Site Summary

Program Description
(VCP, brown fields, or related)

During the 2005 legislative session, House Bill 1341 was
passed by the Mississippi legislature and signed by the
governor. The Mississippi Brownfields Voluntary Cleanup
and Redevelopment Incentives Act contains a number of
financial incentives for property owners and local
governments to clean up and redevelop brownfields
properties. The legislation also provides additional financial
assistance to counties and municipalities. The Act expands
eligible projects for financial assistance under the Local
Governments Capital Improvements Revolving Loan
Program to include remediation of brownfields sites and
created the Local Governments Brownfields
Redevelopment Grant Fund to include financial assistance
for identification of brownfields sites, site assessments and
development of remedial action plans.

Brownfields definition: Real property, the expansion,
redevelopment, or reuse of which may be complicated by
the presence or potential presence of a hazardous
substance, pollutant, or contaminant.

•	Uncontrolled Site definition—Site, facility, plant, or
location where hazardous or toxic wastes have been
released to the environment and, due to existing
regulations, there is no federal program that can handle
the problem.

•	Voluntary Evaluation Program (VEP)—Uncontrolled site
that is voluntarily participating in the Voluntary
Evaluation Program.

Program titles:

•	Mississippi Brownfields Program

•	Uncontrolled Sites Program

•	Voluntary Evaluation Program

Liability relief provisions: Brownfields parties who
execute a brownfields agreement shall be relieved of
liability to all persons, including MDEQ (other than the
United States) for remediation of the brownfields

agreement site other than the remediation required by the
brownfields agreement, and all costs reasonably related to
the remediation other than the remediation costs required
by the brownfields agreement or the regulations. For sites
cleaned up to unrestricted levels, a No Further Action letter
is issued.

Uncontrolled Sites/VEP Program—For sites with
contamination left in place above unrestricted levels, a
Restrictive Use Agreed Order has the following
language: (a) the staff of the Commission has evaluated
this Restrictive Use Agreed Order and believes once the
requirements of it have been completed that 1) the site will
be protective of the public health and the environment and
2) no further corrective action will be required at this time;
(b) for sites cleaned up to unrestricted levels, a No Further
Action letter is issued.

Financial incentives (grants, loans, tax provisions, etc.):

MDEQ conducts limited assessments (Phase I
Environmental Site Assessments (ESAs), limited Phase II
ESAs) for eligible entities (See federal Brownfields Law
Subtitle A definition) on a competitive basis.

Legislative or program site eligibility requirements: A

brownfields party must provide MDEQ with information
necessary to demonstrate that: 1) the proposed remediation
will result in a suitable use for the property (as stated in the
application) and will protect public health and the
environment; 2) the party can obtain the financial,
managerial, and technical resources to complete the
proposed remediation and assure the safe use of the
brownfields property; 3) the current owner of the
brownfields property is an applicant or has given written
approval for submission of the application; 4) the
brownfields party will comply with all applicable procedural
requirements; and 5) the brownfields party will agree to pay
for MDEQ oversight costs.

Financial Elements

Assessment and cleanup funding (source, amount,
relationship to VCP/brownfields programs, application
process, eligibility requirements, dedication to special
types of sites such as petroleum, dry cleaners,
abandoned drug labs, etc.): MDEQ conducts limited
assessments for eligible entities on a competitive basis.
There is EPA funding to MDEQ for environmental
assessments at brownfields sites throughout the State of
Mississippi under the Targeted Brownfields Assessment
Program.

The Brownfields Voluntary Cleanup and Redevelopment
Incentives Act expands eligible projects for financial
assistance under the Local Governments Capital
Improvements Revolving Loan Program to include
remediation of brownfields sites and creates the Local
Governments Brownfields Redevelopment Grant Fund to
include financial assistance for identification of brownfields
sites, site assessments and development of remedial action
plans. The maximum grant under this program is $100,000,
and requires a 25 percent local match. In addition, the
legislation authorizes $2.5 million in state general

62

State Brownfields and Voluntary Response Programs:


-------
obligation bonds to be used by local governments for
remediation of identified properties

Tax incentives (abatements, credits, etc.): The

Brownfields Voluntary Cleanup and Redevelopment
Incentives Act provides an income tax credit for a property
owner equal to 25 percent of the costs of remediating a
brownfields property, with the annual credit capped at
$40,000, and the total credit not to exceed $150,000. Any
unused portion of the tax credit may be carried over into
succeeding tax years. In lieu of the state income tax credit,
the property owner may claim a job tax credit for each new
employee created as a result of the cleanup and
redevelopment of a brownfields site.

Other forms of support (environmental insurance,
brownfields redevelopment authorities, etc.):

No information available

Program Elements
Technical Elements

Methods/standards/controls: The brownfields program
uses a three tiered risk-based approach to remediation. Tier
1 evaluation compares site-specific data to a table of
chemical-specific Target Remediation Goals (TRGs). Tier 2
provides the applicant the option of performing a more in-
depth evaluation of site-specific conditions to develop site-
specific Remediation Goals (RGs). Tier 3 is a site-specific
risk assessment to evaluate the potential human health and
ecological risks at the site that will result in the
development of site-specific RGs.

Contaminants covered/excluded: Asbestos, lead paint,
polychlorinated biphenyls (PCBs), and petroleum are
covered.

Use of long-term stewardship and institutional controls
(tracking, oversight, monitoring, re-openers): The state
statute promotes evaluation of institutional controls, and
other remedial options for a site that can shut-off or
eliminate exposure to contamination.

Management & Implementation Elements

Voluntary Cleanup Program MOA with EPA: No

Costs to enter program or fees for service: At the time a
Brownfields Agreement application is filed, the applicant
agrees to pay MDEQ all reasonable and direct costs
associated with the administration of the application at the
rate of $75/hour, and must attach a $2,000 application fee.
An applicant under the Uncontrolled Sites VEP, must also
agree to pay MDEQ all reasonable and direct costs
associated with the administration of the application at the
rate of $75/hour.

Funding source for administrative costs and staff: The

Brownfields Cleanup and Redevelopment Trust Fund pays
for reasonable direct and indirect costs associated with the
processing of the Brownfield Agreement applications and
the administration of Brownfields Agreements. Money in the
Uncontrolled Site Evaluation Trust Fund shall be utilized to
pay reasonable direct and indirect costs associated with

the administration and evaluation of uncontrolled sites,
including, but not limited to, the reasonable costs of
reviewing plans, specifications, engineering reports
and other documents related to site assessments;
establishing cleanup levels; and preparing
requirements and guidance.

Cleanup Activities

Sites currently in VCP: 206

Sites completed under VCP: 34

Benefits (incentives to participate in theVCP,
covenants not to sue, etc.): Uncontrolled Site VEP
allows accepted parties the opportunity to participate in
a program that will expedite the evaluation of site
information. The brownfields program offers liability
protection before cleanup (at the point that a
brownfields agreement is reached) eliminating the
need for a No Further Action letter typically used after
cleanup to unrestricted use. Six sites are currently in
this program and have received such liability
protection.

Public Participation

Public participation requirements (notice, comment
periods, etc.): If the department and a brownfields
party reach a proposed agreement for the remediation
of a brownfields agreement site, MDEQ must publish a
public notice in a newspaper of general circulation in
the county or counties in which the Brownfields
Agreement site is located. The public notice shall: 1)
describe the proposed agreement and site; 2) request
public comment on the proposed agreement; and 3)
provide the date and location of the commission's
consideration of the proposed Brownfields Agreement.
A copy of the proposed Brownfields Agreement shall
be filed for public inspection.

Public participation activities (hearing, meetings,
etc.): MDEQ may conduct a public hearing on the
proposed Brownfields Agreement. MDEQ shall publish
a notice of the hearing in a newspaper of general
circulation in the county or counties in which the
proposed Brownfields Agreement site is located.

MDEQ shall provide to the commission for review
before its consideration of the proposed Brownfields
Agreement all public comments and the transcript of
any public hearing on the proposed Brownfields
Agreement.
