Black-tailed prairie dogs won't be getting any protection under the federal Endangered Species Act, but comments on the review of a blood-thinning poison are now starting to flow in to the Environmental Protection Agency.

The number of comments aren't big, but now exceed 100, with nearly half those filed this week.

The deadline for submitting comments on the EPA's registration of Rozol is noon Monday.

It's uncertain when a decision might be made on the review.

The issue before the EPA involves the registration and use of Rozol, a blood-thinning poison containing chlorophacinone, to control prairie dogs.
