    (B) For submerged areas, either:
      (i) a shot in excess of 20 pounds of dynamite equivalent; or
      (ii) a shot hole less than 120 feet below the mud line.
  (3) With respect to energy-related activities not covered within the scope of a hard mineral plan of operations, the GLO's or SLB's issuance of a surface lease (pursuant to the Texas Natural Resources Code, §51.121), or a coastal easement (pursuant to the Texas Natural Resources Code, §33.111), exceeds the threshold only if the instrument authorizes:
    (A) permanent disturbance of five acres or more of a critical area or removal of more than 10,000 cubic yards of material from a critical area, except with respect to submerged aquatic vegetation and tidal mud or sand flats in the lower coast; or
    (B) permanent disturbance of ten acres or more of submerged aquatic vegetation or tidal mud or sand flats in the lower coast.
(d) A miscellaneous easement issued pursuant to the Texas Natural Resources Code, §51.291, exceeds the threshold for potential referral if the miscellaneous easement authorizes:
  (1) permanent disturbance of five acres or more of a critical area or removal of more than 10,000 cubic yards of material from a critical area, except with respect to submerged aquatic vegetation and tidal mud or sand flats in the lower coast; or
  (2) permanent disturbance of ten acres or more of submerged aquatic vegetation or tidal mud or sand flats in the lower coast.
(e) Any GLO or SLB action described in §16.1 of this title (relating to Definitions and Scope) that may adversely affect a CNRA that has not been specifically addressed in this section, exceeds the threshold if the action would adversely affect greater than 40 acres of any such CNRA.
