  (1) Agency or subdivision--Any state agency, department, board, or commission or political subdivision of the state.
  (2) Adverse effects or adversely affect--Effects that result in the physical destruction or detrimental alteration of a CNRA. Such detrimental alterations are:
    (A) construction in critical dune areas and coastal hazard areas that increase risks to human safety or the potential for damage to property or CNRAs from floods, hurricanes, or other storms;
    (B) alterations that interfere with public use and enjoyment of, or access to and from, those CNRAs to which the public has a right of use, enjoyment, or access;
    (C) alterations that damage or destroy coastal historic areas;
    (D) alterations that harm the functions and values of CNRAs as habitat for terrestrial and aquatic wildlife;
    (E) alterations that disrupt wildlife corridors or fish or bird migratory routes;
    (F) discharges of pathogens, radioactive materials, dissolved minerals or solids, toxic substances, or suspended solids at levels harmful to humans or terrestrial or aquatic life or that significantly impair the aesthetic qualities of CNRAs;
    (G) alterations of salinity regimes, nutrient supply, oxygen concentration, or temperature regimes in coastal waters that are harmful to terrestrial or aquatic life;
    (H) alterations of hydrology, water flow, circulation patterns, water level, or surface drainage that are harmful to humans or terrestrial or aquatic life, impair the aesthetic qualities of CNRAs, or exacerbate erosion of shorelines or river deltas;
    (I) alterations of littoral and sediment transport processes that reduce the supply of sediments available to those processes or would otherwise exacerbate erosion of shorelines or river deltas;
    (J) alterations that increase losses of shore areas or other CNRAs from a rise in sea level with respect to the surface of the land, whether caused by actual sea-level rise or land surface subsidence; and
    (K) emission of air pollutants at levels that are harmful to humans or terrestrial or aquatic life or that significantly impair the aesthetic qualities of CNRAs.
  (3) Avoid and otherwise minimize--To avoid adverse effects to the greatest extent practicable. Adverse effects that cannot be avoided must then be minimized to the greatest extent practicable.

  (14) Pollutant--Any constituent that contaminates or alters the physical, thermal, chemical, or biological quality of any CNRA so as to be harmful, detrimental, or injurious to humans, animal life, vegetation, or property or to the public health, safety, or welfare or that impairs the usefulness or the public enjoyment of CNRAs for any lawful purpose.
  (15) Practicable--Available and capable of being done after taking into consideration existing technology, cost, and logistics in light of the overall purpose of the activity.
  (16) Public beach--Any public beach as defined in Chapter 61 of the Texas Natural Resources Code.
  (17) Secondary adverse effects--Adverse effects which would result from a proposed action and cause significant modifications or alterations to the physical or chemical characteristics of coastal natural resource areas beyond the limit of the immediate project area.
  (18) Water-dependent use or facility--An activity or facility that must be located in coastal waters or on submerged lands or that must have direct access to coastal waters in order to serve its basic purpose and function. Facilities that are water-dependent include, but are not limited to, public beach use and access facilities, boat slips, docks, breakwaters, marinas, wharves and other vessel loading or off-loading facilities, utility easements, boat ramps, navigation channels and basins, bridges and bridge approaches, revetments, shoreline protection structures, culverts, groins, saltwater barriers, navigational aids, mooring pilings, simple access channels, fish processing plants, boat construction and repair facilities, offshore pipelines and constructed wetlands below mean high water.
