The Interior Department's of Bureau of Land Management has a long set of proposals that would according to the Washington Post roll back environmental reviews on public lands. As part of the proposals, BLM has, among other things proposed battling FOIA requesters by attempting to limit the number of requests one individual or entity can make and attempt to narrowly construe fee waiver requests. Muckrock has this write up on the proposals as they relate to FOIA.
BLM proposes to make these changes by either legislation or regulation. Obviously, legislation requires the House and Senate to go along with these proposals and it would be a major feat if one component of one agency can get a FOIA carve out to allow public lands to be given over to corporate interests without any transparency.
As to regulation, regulation is based on law. There is no law that allows an agency to limit requests by an entity as it relates to BLM. Further, FOIA fees do not go back to the agency, they go to the general treasury. BLM proposes charging as much as possible to requesters to recover its FOIA costs. If BLM knew anything about the FOIA process, they would know that this is not allowed by law - thus regulations can't be implemented to do it.
If BLM really wants to lessen their FOIA costs, I would propose the following:
1. Hire serious individuals who are FOIA professionals and understand how the system works. These employees should be able to work well with submitters and requesters in a non-adversarial manner.
2. Send employees to FOIA training- if the person writing this memo had gone to training I and others presented on FOIA fees, they would know that the FOIA fees provision is unworkable.
