All Appropriate Inquiries  Rule:
                   Reporting Requirements and Suggestions on
                   Report Content
 WHAT is "ALL APPROPRIATE INQUIRIES"?
  "All appropriate inquiries" is a process of evaluating a property's environmental conditions
 and assessing potential liability for any contamination.  All appropriate inquiries must be
 conducted to obtain certain protections from liability under the federal Superfund Law
 (CERCLA).

 WHY DID EPA ESTABLISHING STANDARDS FOR CONDUCTING ALL APPROPRIATE
 INQUIRIES?
 The 2002 Brownfields Amendments to the Comprehensive Environmental Response
 Compensation and Liability Act (CERCLA ) require EPA to promulgate regulations
 establishing standards and practices for conducting all appropriate inquiries.

 WHEN is THE ALL APPROPRIATE INQUIRES RULE EFFECTIVE?
 The final rule is effective on November 1, 2006, one year after its publication date in the
 Federal Register.

 WHAT ARE THE DOCUMENTATION REQUIREMENTS FOR ALL APPROPRIATE INQUIRIES?
 The final rule requires that the results of an all appropriate inquiries investigation be
 documented in a written report. The specific reporting requirements for all appropriate
 inquiries are provided in 40 CFR §312.21 (Results of Inquiry by an Environmental
 Professional) and §312.31 of the final rule and  include:

  I. An opinion as to whether the inquiry has identified conditions indicative of releases or
    threatened releases of hazardous substances on, at, in, or to the subject property.

 II. An identification of data gaps (as defined in §312.10) in the information collected for the
    inquiry that affect the ability of the environmental professional to identify conditions
    indicative of releases or threatened releases of hazardous substances on, at, in, or to the
    subject property, as well as comments regarding the significance of these data gaps.

III. Qualifications and signature of the environmental professional(s). The environmental
    professional must place the following statements in the document and sign the document:

     ' '[I, We] declare that, to the best of [my, our] professional knowledge and belief, [I, we] meet the definition
    of Environmental Professional as defined in §312.10 of this part.''

     ' '[I, We] have the specific qualifications based on education, training, and experience to assess a property of
    the nature, history, and setting of the subject property. [I, We] have developed and performed the all
    appropriate inquiries in conformance with the standards and practices set forth in 40 CFR Part 312.''

IV. In compliance with §32.3 l(b), the environmental professional must include in the final
    report an opinion regarding additional appropriate investigation, if the environmental
    professional has such an opinion.

-------
Is THERE A REQUIRED FORMAT FOR REPORTING RESULTS OF ALL APPROPRIATE INQUIRIES?

The final rule requires no specific format, length, or structure of the written report. However,
EPA offers the following suggestions regarding the potential content of a written report.  The
following suggestions generally are consistent with recommendations published in ASTM
El 527-05, Standard Practice for Environmental Site Assessments: Phase I Environmental
Site Assessment Process.  The ASTM E 1527-05 standard is consistent with the requirements
of the final rule and may be used to comply with the provisions of the rule. The following are
suggestions regarding format and content of an all  appropriate inquiries written report. Please
note that the suggestions below do not represent regulatory requirements.  Prospective
landowners and environmental professionals may design their own format for a written
report, as long as the report contains the four documentation requirements listed above (and
as noted below).

>  Introduction. An introduction could include descriptions of: the purpose and objectives of the
    assessment; scope of services provided; methodology used to  complete the inquiry; any
    significant assumptions made; limitations and exceptions; any modifications or deviations from
    the final rule requirements or from the ASTM E 1527-05 process; special terms and conditions;
    and information obtained from the landowner or user. The environmental professional and the
    person(s) who conducted the site reconnaissance and interviews may be identified.

>  Site Description. This section may describe the property location; site and vicinity characteristics;
    structures, roads, site improvements, and utilities; current and historic use(s) of the property; site
    topography, geology, and surface/ground water resources; and current and historic use(s) of
    adjacent properties.

>  User-Provided Information. The report may describe any information provided by the
    prospective landowner, or user, to the environmental professional. This information may include:
    title records; information of recorded environmental cleanup liens; recorded activity and use
    limitations (e.g., engineering controls, land use restrictions, institutional controls); specialized
    knowledge or experience held by the user related to the property or nearby properties; commonly
    known or reasonably ascertainable information; and relationship of the purchase price to the  fair
    market value of the property, if it were not contaminated.

>  Records Review. The written report may include a section that summarizes the information found
    during the records review.  This section may describe records that were reviewed to complete the
    inquiry including: physical setting sources (e.g., topographic maps); historical use sources (e.g.,
    aerial photographs, fire insurance  maps, street directories, newspaper archives); federal, state,
    tribal, and local records or databases of government records; and other environmental record
    sources (e.g., prior investigation reports, tank/transformer inventories, spill records, permits,  etc.).

>  Site Reconnaissance. The written report may include a section dedicated to describing the
    methodology used to conduct the visual inspection  of the subject and adjoining properties. The
    description may include: when and who performed  the reconnaissance; physical imitations (e.g.,
    snow-covered ground, limited access, safety concerns, etc.); general site setting; exterior
    observations; and interior observations. Additional  information on evidence of staining, spills,
    odors, stressed vegetation, corrosion, pools of liquids, discolored water, ground surface
    alterations, and other conditions that might suggest a release or threatened release of hazardous
    substances also may be provided.

>  Interviews. A summary of the interviews conducted could include a description of when and with
    whom the interviews were conducted (e.g., current  property owner and occupants, site manager,
    attorneys, financial manager, local/state/federal government officials, past site owners and

-------
    occupants) and the method used to conduct the interviews (e.g., in person, written, telephone). If
    property is abandoned, this section may describe which neighboring property owners were
    interviewed and if applicable, which past owners and occupants were interviewed.

>   Findings. A findings section could describe the results of the assessment including the identified
    known or suspected recognized environmental conditions, historical recognized environmental
    conditions, and de minimis conditions. This section also may include findings related to, but not
    limited to: current and historic site usage; adjoining and nearby properties; hazardous substances
    and petroleum products; non-hazardous, solid, and hazardous waste management; water
    pollution; pits, ponds, and lagoons; drains and sumps; waste water; wells; septic systems; spills or
    releases; air emissions; storage tanks and drums; soil and groundwater contamination,
    poly chlorinated biphenyls (PCB) contaminants, or other contaminants.

>   Opinion of the Environmental Professional.  In compliance with the all appropriate inquiries
    final rule at §312.21(c)(l), the written report must include the environmental professional's
    opinion(s) as to whether the inquiry identified conditions indicative of releases or threatened
    releases of hazardous substances on, at, in, or to the subject property. The opinion likely will be
    based on  conditions identified during the inquiries (and potentially noted in a findings section),
    and include a discussion of the logic, reasoning, and rationale used by the environmental
    professional in developing the opinion. The  environmental professional also must include in the
    final report an opinion regarding additional appropriate investigation to detect the presence
    of contamination at the property, if the environmental  professional has such an opinion.

>   Data Gaps. As required in  §312.21(c)(2) of the final rule, the  report should document and
    discuss significant data gaps that affect the ability of the environmental professional  to identify
    conditions indicative  of releases or threatened releases.

>   Conclusions. A conclusions section may be included that summarizes all identified conditions
    indicative of releases or threatened releases of hazardous substances (or recognized
    environmental conditions) connected with the property. The final rule does not require that any
    specific statements be made regarding these conditions, however, ASTM E 1527-05  requires that
    the report include one of the following written statements:

       o   "We have performed a Phase I Environmental Site Assessment in conformance with the scope and
           limitations of ASTM Practice E 1527 of [insert address or legal description], the property. Any
           exceptions to, or deletions from, this practice are described in Section [ ] of this report. This
           assessment has revealed no evidence of recognized environmental conditions in  connection with
           the property," or
       o   "We have performed a Phase I Environmental Site Assessment in conformance with the scope and
           limitations of ASTM Practice E 1527 of [insert address or legal description], the property. Any
           exceptions to, or deletions from, this practice are described in Section [ ] of this report. This
           assessment has revealed no evidence of recognized environmental conditions in  connection with
           the property except for the following: (list). "

>   Additional Services. If applicable, it may be useful to include a description of any additional
    services performed as part of the assessment that are beyond the scope of the final rule, and were
    contracted for between the user and the environmental professional. Additional services could
    include, but are not limited to: non-scope considerations (e.g., lead-based paint, mold, radon,
    asbestos,  regulatory compliance assessment, indoor air quality, etc.); broader scope of
    assessment; liability or risk evaluations; Phase II sampling and analysis; health and safety;
    evaluation of remediation techniques; etc.

>   References. A reference section may be included that lists the published sources relied upon to
    complete the assessment.

-------
>  Signature(s) and Qualifications of the Environmental Professionals). Include the statements
    and environmental professional(s) signature required by §312.21(d), as discussed above in "What
    are the Documentation Requirements for All Appropriate Inquiries?"

>  Appendices. Appendices could include: regulatory records documentation; environmental
    database report; site map/plan; vicinity maps; site photographs; historical source documentation
    (building department records, local street records, chain of title documents, property tax records,
    zoning/land use records, aerial photos, fire insurance maps, USGS topographical maps); interview
    documentation; and qualifications of the environmental professional(s).
