SUFFOLK COUNTY DEPARTMENT OF HEALTH SERVICES
ARTICLE 12--SOP NO. 9-95
PUMPOUT AND SOIL CLEANUP CRITERIA
STATEMENT OF PURPOSE
Article 12 of the Suffolk County Sanitary Code,requires the owner,operator or any other person in
possession or control of an industrial facility to report to the Department of Health Services (the
Department) any unauthorized discharge, leak or spill of toxic or hazardous material within two
hours of knowledge of that discharge, leak or spill. Knowledge of a spill includes information
generated during Phase I and Phase II Environmental Assessments,such as results from groundwater
and soil sampling. In addition,Article 12 requires the owner, or any other person in possession or
control of the source of the discharge,and/or the owner of the property onto which the discharge has
occurred,to immediately cease the discharge and to reclaim,recover and dispose of the discharged
material and to restore the environment to the condition that existed prior to the discharge.
Since it is not always possible to achieve predischarge conditions,this document was generated to
provide guidance when evaluating the potential impact of a discharge on the environment and to
provide assistance when determining if,and to what extent,contaminated liquids and/or solids must
be removed from sanitary systems,storm drains,or other locations at a facility. It was generated to
be applicable to most situations; however, the Department reserves the right to apply additional
requirements when warranted by conditions encountered at a particular site.
This document is not meant to represent approval by the Department of any remedial activities,or to
represent the Department's determination that a site either does or does not require remediation. All
spills, leaks, or discharges of toxic or hazardous materials, as defined by Section 760-1203 of the
Sanitary Code, must be reported to the Office of Pollution Control, which will have the sole
authority to determine what, if any, cleanup will be required.
When assessing the need for cleanup at a specific site, in addition to the potential for migration of
contaminants to groundwater the Department will consider all human health and environmental
factors that are available, including the potential for direct exposure via dermal absorption,
inhalation or ingestion pathways. The soil cleanup objectives contained in this document do not
account for potential soil vapor or soil vapor intrusion impacts.In many cases,site specific cleanup
criteria may vary from the values listed in this SOP.
Be advised that,in addition to meeting the Suffolk County Department of Health Services(SCDHS)
requirements,the responsible party must meet the requirements of the New York State Department
of Environmental Conservation(NYSDEC)and the United States Environmental Protection Agency
(USEPA).

CRITERIA
As stated in Articles 7 and 12 Suffolk County Sanitary Code, it is the policy of the County of
Suffolk to maintain its water resources as near to their natural condition of purity as reasonably
possible. As such,the goal of any remedial action required by this Department is to return the
site to predischarge conditions. If this is not possible, at a minimum, the cleanup must ensure
reasonable protection for public health and the environment.
Appendices A,B and C contain Action Levels and Cleanup Objectives for Volatile Organic
Compounds (VOCs), metals and Semi-Volatile Organic Compounds(Semi-VOCs),respectively.
When the concentration of a single contaminant, or a class of contaminants such as total
petroleum hydrocarbons, meets, or exceeds, the "Action Level", a cleanup, or other action, is
required. Under most conditions,the contaminant concentration in the soil after remediation
should not exceed the values indicated in the "Cleanup Objective" column.
Cleanup Objectives for VOCs and Semi-VOCs were established in a manner consistent with
the New York State Department of Environmental Conservation's Technical and
Administrative Guidance Memorandum, (TAGM) HWR-94-4046. Where measured Soil
Partitioning Coefficients (Kos) could be found, they were used. If not,the Kos was
calculated based on the compound's Octanol/Water Partitioning Coefficient(Kow). If the
Kow was not available, the Kos was estimated based on solubility. Individual VOC and
Semi-VOC Cleanup Objectives were capped at a maximum allowable concentration of
100,000 ppb.
Cleanup Objectives for metals have been revised from those listed in the original document
to more closely conform to the groundwater protection cleanup objectives contained in
6NYCRR Part 375. Cleanup Objectives for metals assume a 20:1 Dilution Attenuation
Factor(DAF), consistent with Part 375. Action Levels for metals assume a DAF of 100.
In order to perform a proper environmental evaluation, the Department may require additional
analysis to be performed based on the chemicals stored, or in use, at a site. This may include
Total Petroleum Hydrocarbons (TPH), cyanides, phenols, PCBs,pesticides and/or a more
extensive list of metals, VOCs and/or Semi-VOCs. Cleanup objectives and action levels for these
additional parameters will be established on a case by case basis.
Although TPH analysis is not normally required by this Department, if the analysis is performed
on a sample and the TPH concentration is greater than, or equal to, 500 ppm,the Department
will require the responsible party to analyze the sample for Semi-VOCs via EPA Method 8270.
The results of this analysis will then be compared with the Semi-VOC values listed in Appendix
C.
Liquid endpoint samples must be collected if groundwater is encountered during a cleanup
operation. If the concentration of VOCs, Semi-VOCs or metals in the sample exceeds 100 times
the contaminant's discharge standard, the Department will require a groundwater sample to be
collected immediately downgradient of the point of contamination to determine if there has been
an impact on the groundwater. If significant groundwater contamination is found, a more
extensive groundwater investigation will be required. The Department reserves the right to
require the installation of monitoring well(s) at lower contaminant levels based on the type
4
of contaminant encountered and other site specific conditions.
Other factors to be considered when evaluating a site
In many instances, additional information is available which the Department will utilize when
establishing cleanup goals, or action levels, for a specific site. Some factors that are considered
when reviewing site specific conditions to decide if cleanup goals should be set higher or lower
than the guidance values listed in this document include, but are not be limited to:
Site history- Past discharge practices, as well as the extent and type of
discharge discovered,will be considered.
Type of Contaminant- Physical and/or chemical characteristics of a contaminant
will be considered. For example,the department may require
groundwater sampling, and/or a soil vapor investigation to
be undertaken, due to high concentrations of
tetrachloroethene and/or its breakdown products detected in
initial samples even though soil cleanup objectives were met
in post remediation samples.
Site location- Facilities located in water sensitive areas or near drinking
water wells may require more stringent cleanup objectives.
Distance to groundwater- Since this guidance document assumes a 100 fold reduction
in contaminant concentrations between the source area and _
the drinking water supply, if the distance between the
contamination and the groundwater is less than three feet, or
a drinking water supply well is located nearby, action levels
or cleanup goals may be lower than the guidance values
listed in this document.
Monitoring well data- If groundwater contamination can be attributed to the
discharge, more extensive remediation or investigation may
be required.
Future use of site- Although it is not this department's policy to allow pockets
of contamination to remain in the ground throughout the
county, in certain cases,where the cleanup objectives listed
in this document can not be achieved, higher concentrations
of contaminants may be allowed to remain in place if the site
can be stabilized in a manner acceptable to the Department.
In these instances, land, or deed,restrictions may be
required.
Direct Human Exposure- If ingestion, inhalation or dermal contact is a concern, other
soil screening guidance documents should be used to
formulate a cleanup goal, especially if that value is lower
than the "Cleanup Objective" listed in this document.

Note: VOC and Semi-VOC contaminants were evaluated in a manner consistent with the New York State Department of
Environmental Conservation's Technical and Administrative Guidance Memorandum(TAGM),HWR-94-4046.
Cleanup objectives were established using the following relationship,subject to a maximum contaminant concentration
of 100,000 ppb. Action levels were generally set at twice the cleanup objective,subject to a maximum contaminant
concentration of 200,000 ppb.Cleanup{{Objectives were calculated using the following:
Cs=(DAF)(f)(Cw)(e)
Where:
C, =Allowable Soil Concentrations(ppb)
DAF =Dilution Attenuation Factor of 100
f =organic fraction in soil(assumed to be 1%,or 0.01)
CW =Water Quality Value(6NYCCR 703.5,or TOGS 1.1.1)in ppb
Ko, =Organic Carbon Partition Coefficient(an approximation of the propensity of
a compound to adsorb to organic matter in the soil)
Metals cleanup objectives were calculated based on the following:
CS=(DAF)(C-.)(Kd)
Where:
C, =Allowable Soil Concentrations(ppm)
DAF =Dilution Attenuation Factor of 20 for Cleanup Objectives and 100 for Action Levels
CW =Water Quality Value(6NYCCR 703.5,or TOGS 1.1.1)in ppm
Kd =Soil Water Distribution Coefficient(partitioning coefficient for inorganics)
