                                 INTRODUCTION



     This report documents the development of checklists for the review of

Superfund Air Pathway Analyses (APAs).   Under the Comprehensive Environmental

Response, Compensation, and Liability Act (CERCLA) and the recent Superfund

Amendments and Reauthorization Act (SARA),  EPA has the responsibility for

assessment and cleanup of Superfund sites.   Because air emissions pose a

potential human health risk at these sites, the EPA developed a four-volume

set of procedures for evaluating these risks entitled Procedures for Conduct-

ing Air Pathway Analyses for Superfund Applications (hereafter referred to as

the NTGS volumes).



     The task of ensuring that all aspects of determining the effects of

airborne pollutants from hazardous waste sites is very complex and therefore a

systematic approach is necessary.  The Checklists presented here are designed

to assist reviewers of EPA documents in systematically applying the proced-

ures. The checklists contain questions on all important aspects of the APA

process to ensure that all significant risks are evaluated.



     Four separate checklists were drafted sequentially and revised according

to EPA comments.  Each checklist coincides with one of the major deliverables

of the Superfund Remedial Action process.  Air pathway assessment techniques

were applied to the Superfund remedial action process to develop the set of

questions which make up each checklist.  Information for the content of the

checklists was drawn from Superfund documents, the NTGS series, other check-

lists, and Radian's experience in  the field.



     This report presents Radian's work under EPA Contract 68-02-4392, Work

Assignment 61.  The report discusses the background, summarizes related

documents, discusses the use of the checklists, summarizes the contents of

-------

          each checklist and provides the final versions of the checklists in the
V        appendix.  A reproducible master set of checklists is provided separately.

                                  BACKGROUND



     Although the methods of air pathway analyses of environmental air

pollutants are reasonably well understood,  the application of these methods to

hazardous waste sites is fairly new.  In addition the problems of estimating

the emissions from the hazardous waste sites are complex because the source

contamination level is rarely known with great precision.  The APA problems

encountered at hazardous waste cleanup sites require techniques specifically

designed for hazardous waste sites.  The NTGS volumes were therefore completed

in 1989 to provide the required techniques.



     The NTGS volumes contain four volumes of detailed procedures for the

following:



     •    An overview and general APA procedures;



     •    Emission estimates from uncontrolled Superfund sites with an

          emphasis on landfills and lagoons;



     •    Emission estimates from remedial activities such as material moving

          and sources such as incinerators and strippers; and



     •    Dispersion modeling and air monitoring methods.



     Technical resources are provided for  the design of measurement programs,

dispersion estimates, emission controls, and impact assessments.  The series

is designed to be used by EPA remedial project managers, enforcement project

managers, air experts, and contractors involved in Superfund remediation

activities.

                       PURPOSE AND USE OF THE CHECKLISTS

     The checklists are intended for use by EPA air reviewers when they are
performing the tasks of reviewing the APAs submitted with Superfund remedial
action documents.  The format of the APAs has been known to vary significantly
from one project to the next.  The organization and presentation of informa-
tion dealing with air pathway analyses can vary.  In some cases, the reviewer
must review large volumes of data to find the required information.  In
consideration of the above variations and difficulties, the checklists are
designed to organize the process of review and to ensure that all necessary
components of the APA are evaluated.

     The APA procedures provide a systematic approach which involves applica-
tion of modeling and monitoring methods to estimate emission rates and
concentrations of air contaminants.   The procedures are designed to be
flexible, allowing professional judgment to vary the performance of the APA.
The checklists reflect the flexibility of the procedures while providing a
systematic format of review.  The checklists are not intended to prescribe the
content and format of the APAs.  They are designed to be applied to many
different styles of Air Pathway Analyses.  It should be possible to apply the
checklist to all Superfund projects, although some projects will not require
application of all the sections of the checklists.

     With a few exceptions,  the checklists do not provide reference data
because the volume of data required would be too great.  Reference data may be
found in the NTGS volumes, in Applicable or Relevant and Appropriate Require-
ments (ARARs), and other engineering and scientific manuals.

     It is expected that the checklists will be reviewed and revised as
regulations and procedures vary and as experience in the use of the checklists
becomes instructive.

     The diversity in Superfund remedial activities require versatility in the

procedures while at the same time the pathway of all known toxins must be

evaluated as accurately as is possible.  The nature of the air pathway

analyses which must be reviewed by the EPA therefore vary significantly from

one project to another.  Therefore a concise but versatile review guidance is

required to help the reviewer determine whether all necessary factors are

evaluated.  This guidance is provided as a set of questions contained in the

checklists which the reviewer can apply to the submitted Superfund documents.



     The EPA has developed a checklist for the review of PSD applications.

The PSD checklist asks specific questions regarding measurements of air

quality parameters.  The four Superfund APA checklists differ from the PSD

checklist  in that they are more general in nature.  This generality is

necessary  because these checklists must deal with the high variability in

Superfund  projects and criteria and non-criteria pollutants while the PSD

checklist  deal with  criteria pollutants.

                     CONTENT AND FORMAT OF THE CHECKLISTS



     The four checklists developed for the review of Superfund documents are

directed towards the deliverable documented results of Superfund projects.

The individual checklists contain an identification section, an instruction

section, some brief information, and sectionalized sets of questions related

to specific portions or the required Superfund process.  The four separate

checklists are titled as follows:



     •    Review Criteria Checklist for the Workplan of the Superfund Remedia-

          tion Process (WP Checklist);



     •    Review Criteria Checklist for the Remedial Investigation Phase of

          the Superfund Remediation Process (RI Checklist);



     •    Review Criteria Checklist for the Feasibility Study Phase of the

          Superfund Remediation Process (FS Checklist); and



     •    Review Criteria Checklist for the Remedial Design Phase of the

          Superfund Remediation Process (RD Checklist).



     The WP checklist prompts the air reviewer to ensure that all the neces-

sary aspects of the remedial investigation and the feasibility study are

contained in the workplan.  Questions concerning existing data on site

conditions, preliminary site measurements, safety, planned analyses, and

scheduling are included in the checklist.



     The RI Checklist presents questions which prompt the reviewer to evaluate

the completeness of the data presented to characterize the baseline conditions

of the site.  Sections on the physical characteristics of the site, the

characterization of the contamination, emission estimates,  dispersion esti-

mates, and ambient monitoring results, and exposure assessments are included.



     The FS checklist includes questions on the physical site characteristics,

site characterization, data quality, and a table for evaluation of each

remedial alternative in respect to the above questions as well as ARARs,

emission controls, waste disposal, emission monitoring, long-term effective-

ness, storage and handling, and overall protection of the environment.



     The RD Checklist contains questions on physical site characteristics,

contaminant characterization, emissions, modeling, monitoring, and a table for

results of questions on particular aspects of the APA for each contaminant

being remediated.  An additional table providing sources of potential ARARs is

provided as a resource.

 INSTRUCTIONS  TO THE REVIEWER:   This  checklist  is  formatted  along  the  lines  of

 the  Air  Pathway Analysis process.  Each work plan section contains  a  number of

 questions indicating what air-related information to  look for.  Each  question

 should be marked according to  the  quality of the  information presented in the

 work plan submission.  We recommend  a scale  of one to four  for  the  quality

 rank (1  - Very Thorough, 2 - Acceptable,  3 - Needs Revision,  4  -  Missing).

 The  deficiencies may then be compiled and summarized  by the reviewer  in a

 format of his/her choice.  Tables  1  and 2 are  attached to assist  the  reviewer

 in checking off requirements for multiple contaminants.


 Section  I relates to the presentation of the site conditions affecting the

 level of contamination and the air pathway.


 Section  II asks questions related  to preliminary  site measurements  which may

 have been made in order to adequately characterize the contamination  at the

 site for the purpose of scoping and  planning.   These  preliminary  measurements

 may  or may not have actually been  performed.


 Section  III contains questions on  the characterization of the contamination

 with air pathway potential. Amounts, concentrations, risk  analyses,  and

 emission descriptions are examined.   This section examines  the quality of the

 information that the RPM is using  as a basis for  the  RI.


 Section  IV includes questions  which  will help  determine whether or  not the

 planned  measurements and analyses  will provide sufficiently accurate  and

 complete information to assess the risks to  the environment due to  the

 baseline site conditions and the remedial activities.

           REVIEW CRITERIA CHECKLIST FOR THE REMEDIAL INVESTIGATION
                  PHASE OF THE SUPERFUND REMEDIATION PROCESS

                                (RI CHECKLIST)
                              SITE  IDENTIFICATION

Site Name:	Account No.j_
Operable Unit:	County/State:	
Project Manager:	Branch:	Phone:
Air Reviewer:	Branch:	Phone: _
Date Document Received:	Date Review Completed:	
INSTRUCTIONS TO THE REVIEWER:  This checklist is formatted along the lines of
the Air Pathway Analysis process.  Each work plan section contains a number of
questions indicating what air-related information to look for.  Each question
should be marked according to the quality of the information presented in the
work plan submission.  We recommend a scale of one to four for the quality
rank (1 - Very Thorough, 2 - Acceptable, 3 - Needs Revision, 4 - Missing).
The deficiencies may then be compiled and summarized by the reviewer in a
format of his/her choice.

Tables 1, 2, and 3 are provided to aid the reviewer in tracking the
performance of the RI for each contaminant.  If the potential air contaminant
is identified in the work plan it should be tracked in the RI report through
the stages of the APA.  The reviewer may want to assign an identification
number to each contaminant of interest and use the same identification in each
table.  The reviewer may enter a 'Y' on 'N' in appropriate cells to indicate
sufficiency of the submission, or she/he may choose to enter values for easy
access later in the review process.

Part A contains the baseline risk assessment review under the following
sections:

     I    PHYSICAL CHARACTERISTICS OF THE SITE
     II   NATURE AND EXTENT OF CONTAMINATION
     III  EMISSION ESTIMATES
     IV   ATMOSPHERIC DISPERSION ESTIMATES
     V    AMBIENT AIR MONITORING RESULTS
     VI   EXPOSURE ASSESSMENT

 Part B contains a question on the estimates of disturbed site emissions.

1.   [Note:  Question 1 is of critical importance.]   Have
     the level and extent of contamination of surface-water,
     sediment, soil, and ground-water been determined?        	  	
     Has the uncertainty of estimates been sufficiently
     defined?
NOTES:
     Does the analysis sufficiently characterize volatiles
     or hazardous inorganics with air release potential?
     A contaminant characterization matrix is attached
     which will aid the reviewer in checking that all
     required data on each contaminant is addressed.
NOTES:
3.   Has the source of the waste been identified?  (Sources
     may include petroleum refining, pesticide production,
     petrochemical or chemical manufacturing, etc.)

_             deemed necessary, were in-depth survey technologies
•             then implemented?
          NOTES:
          7.   If the screening study was deemed to sufficiently
               •characterize the air pathway, does the reviewer concur
               (i.e., decision to terminate the APA due to lack
               of impact)?

8.   Does the emission model fully describe the waste
     characteristics:


     a.   Volatiles -  vapor pressure, Henry's Law constant,
          water solubility, temperature?
     b.   Particulates - rainfall, wind speed, physical
          state of waste, porosity and density of soil,
          moisture content of soil?
NOTES:
     How were the indicator chemicals selected (also
     called "target compounds")?  Did the contractor follow
     the methodology for selecting these compounds for
     assessing human health risks as described in the
     "Superfund Public Health Evaluation Manual"
     (U.S.EPA, Oct. 1986)?
NOTES:
10.  Does the report relate the selection of indicator species
     to the ideal indicator as described in Volume II, NTGS
     APA manual (p. 36)?
NOTES:
11.  After selection of the indicator chemicals,  is there
     discussion of a final check to be made during remedy
     selection to ensure that the proposed strategy will
     address risks posed by the full range of contaminants
     at the site?
NOTES:
12.  Do the emissions rates correlate with information
     available on the types of waste contained at the site
     (i.e., presence of waste solvents resulting in
     volatile emissions, presence of asbestos waste
     resulting in particulate emissions)?

Potential Routes of Migration


13.  Did the report consider all soil/waste characteristics
     which would affect migration (i.e., adsorption or
     absorption properties of the soil, solubility in
     water, microbial action of soil, moisture content
     of soil)?

II.    SITE CHARACTERIZATION


The nature and extent of the contamination at the site should be defined in
sufficient detail for calculation of the rates and duration of remedial
operations for each of the alternatives evaluated.  Table I of the RI Check-
list may be of assistance in evaluating the submission in more detail.
Following are the key items:
                                                             N/A  Page I   R
1.  Distribution, volumes, and concentrations
    of contaminants.


2.  Physical, chemical, and toxic properties
    of contaminants.


3.  Media descriptions and properties.


4.  Physical location and containment.


Comments:	
III.   DATA QUALITY


The confidence of estimates should be maximized by the use of the highest
quality data available.  The following guidelines apply:
                                                             N/A  Page 4   R
1.  Are site-specific measurements used whenever
    possible?


2.  If models are used, are site-specific measurements
    used for inputs whenever available?


3.  Are tabulated default values (used only when
    measured data are not available) supported by
    literature?


4.  Is the data quality sufficient for the feasi-
    bility study?

INSTRUCTIONS TO THE REVIEWER:    The controls required to protect health and
environment should be determined and any deficiencies in the RD should be
identified.  The extent of the modeling and monitoring (process and ambient)
must be evaluated to determine the adequacy of environmental protection
defined in the RD.  We recommend a scale of one to four for the quality rank
(1- Very Thorough, 2- Acceptable, 3- Needs Revision, 4- Missing).  A space is
provided for the page number in the document where the relevant information is
found and N/A-Not Applicable.  The deficiencies may then be compiled and
summarized by the reviewer in a format of his/her choice.


A table is provided to track the completeness of the remedial design APA
(Table 1).


A table of sources of potential Superfund ARARS is attached (Table 2).


The checklist contains the following sections.


     I.    Physical  Site  Characteristics


     II.   Characterization of  Contamination


     III.  Emissions


     IV.   General


     V.    Modeling

I.   PHYSICAL SITE CHARACTERISTICS
The features of the site and vicinity should be described in sufficient detail
to enable a thorough Air  Pathway Analysis (evaluation of modeling, monitor-
ing, and risk assessment if necessary) for the remedial design.  The features
which should be described are:
                                                        N/A     Page#      R


1.   Contour and land use maps of waste area and        	     	     	
     surroundings?


2.   Schematic diagrams of facilities and other         	     	     	
     data relevant to emissions  (location, height,
     temperature, velocity of emissions, and
     structural measurements?


3.   Distance and direction  to susceptible receptors    	     	     	
     (as determined  from modeling results) (eg.
     nearest residences and  population centers,
     especially schools, hospitals, retirement homes,
     and farms, transportation routes, endangered
     species) from potential emission sources?


4.   Meteorological  and climatological factors.         	     	     	
     (Seasonal wind  roses, precipitation temperature,
     and description of severe weather and topographic
     effects.)

II.  CHARACTERIZATION OF CONTAMINATION:
The nature and extent of the contamination at the site should be defined in
sufficient detail for calculation of the rates and duration of remedial
operations.  The physical and chemical characteristics of the waste and the
contaminated media should also be described and grouped to ensure proper
assessment techniques are applied.  The descriptions should be directly
related to the risks that the contamination poses to exposure via the air
pathway.
                                                        N/A     PageV/      R
1.   Are the physical characteristics of the
     contaminated media described (e.g., soil &
     geology, surface water, size and distribution
     of contaminated or potentially contaminated
     media, possible routes of migration to the
     atmosphere)?


2.   Are the contaminants described in sufficient
     detail to determine the best method of
     measurement and estimation  (e.g., separation
     of contaminants into volatile, semi-volatile,
     liquid and particulate groups)?


3.   Is the description consistent with site history?


4.   Are other contaminants expected even though
     they have not yet been identified?


5.   Are contaminants prioritized according to
     relative risk potential?

     quantified sufficiently?


3.   Are the control methods and control efficiencies   	     	
     defined?


4.   Engineering Design Criteria:
     •    Are air emission-related parameters           	     	
          sufficiently defined for each control
          technology (maximum and average design
          emission rates, stack dimensions, exit
          velocity, design load, operating
          conditions)?
     •    Has sufficient information been included      	     	
          to check the quality of the designs
          (P&ID, PFD, operational descriptions)?
     •    Will sufficient operational monitoring        	     	
          data be collected?
     •    Are acceptance testing and trial runs         	     	
          with sufficient testing planned?

14. SPONSORING AGENCY CODE

The EPA has responsibility for assessment and cleanup of superfund sites. Because
air emissions pose a potential human health risk at these sites, the EPA has developed
a set of procedures for evaluating these risks. The four checklists presented in
this report provide a systematic approach for air reviewers to apply the air pathway
assessment procedures. The background, prupose, and application of the checklists
are discussed.
