See Civil Action No. 6:240-cv-81.The Complaint challenges a rule promulgated by the Service entitled:Endangered and Threatened Wildlife and Plants; Endangered Species Status With Critical Habitat for Guadalupe Fatmucket, Texas Fatmucket, Guadalupe Orb, Texas Pimpleback, Balcones Spike, and False Spike, and Threatened Species Status With Section 4(d) Rule and Critical Habitat for Texas Fawnsfoot (“Final Rule”).See 89 Fed. Reg. 48,034 (June 4, 2024).The referenced species are collectively referenced in the Complaint as “Central Texas Mussels”.The Final Rule lists the Central Texas Mussels as threatened or endangered and promulgates a Section 4(d) regulation to protect the threatened species and establishes a critical habitat for all seven species.The AG alleges that the Service made errors in its promulgation of the final listing determination.The alleged errors are stated to have violated the ESA and the Service’s policies by:Failing to recognize and give consideration owed to Texas’s comprehensive statutory, regulatory, and programmatic conservation efforts to protect the Central Texas Mussels.Failed to provide sufficient specificity in describing what may or may not result in a take of the Central Texas Mussels.The determination was procedurally deficient because it was published nearly three years after the proposed rule which is alleged to be in excess of the one-year publication deadline established by the ESA.The Complaint
