The TCEQ did not have a comment about the pending lawsuit, and Vulcan did not immediately respond to a request for comment.
Errors in the legal process and unaccounted emission sources are among several grievances listed in the lawsuit.
The lawsuit, filed in Travis County, is the latest in the battle over an air permit that was issued for a rock-crushing facility at the quarry.
A water pollution abatement permit must also be issued before Vulcan can begin mining operations.
Vulcan plans to mine 40% of its 1,500-acre property at the intersection of Hwy. 46 and FM 3009 over the next 80 years.
