*Access to historical sources such as city directories, fire insurance maps, and aerial photographs have been somewhat affected, but there are alternate sources and much data already digitized which will satisfy immediate needs.

*Federal websites such as the US Geological Survey (USGS) have been shut down. This hurts our research, but we have identified alternate non-federal (private) options that suffice for the interim.

*Suspended access to the Environmental Protection Agency's (EPA) federal databases and hazardous substances records will prove to be our greatest challenge. Thankfully, the requirement to physically review records pertaining to hazardous substances is usually satisfied on a local (City and County) or State level, and as such won't be affected by the federal shutdown too much.

In cases where required documents are not accessible, Environmental Professionals (EPs) will have to document and address these data gaps as limitations in the report, recommending review of these documents once the agencies are back up and running.

For now, environmental due diligence services can be provided (almost) as normal. However, accessing up-to-date information will become increasingly difficult the longer the shutdown continues. I believe I speak on behalf of the entire due diligence industry when I say I hope the Government reopens as soon as possible!
