REFERENCES

All factual information presented in the report should be documented with reliable sources such as: letters from owners/operators and government agencies; reports on past waste management practices; records of communication with site owners and state and local government; and first-hand observations by qualified government personnel. Information from other sources, such as past employees or nearby residents, can be presented in the report but should not be accepted as fact unless the information has been confirmed.

Attach a complete list of references used to prepare the report. List only those references that document information in the report. Each reference on the list should include (as applicable), the author, or conversation or letter participants, title or subject, date, pages, publisher, and journal name. Include with the report a copy of those references that are site-specific, such as record of communication, letters, or journal articles that are needed to understand the report. Do not attach common references, but identify them and indicate that they are not being included with the report. For books and other publications that are less common, copy title pages and pages referenced.

Photographs are a good way to document releases and other relevant site conditions. Either make color copies of photos, or digitize them. Black & white photocopies of color photos are not useful.

Finally, include a Site Visit Summary in the references. This is a written summary of information gathered during the site visit and should include area measurements of sources (ponds, landfills, etc.), information obtained during the interview, and observations made during the site tour.
