Tier 1 401 Certifications are for small projects that affect
less than 1,500 linear feet of stream and/or 3 acres of waters of the
United States
(HTML) with a few exceptions. A list is provided of best management
practices (BMPs) (PDF / Word
Perfect / MS Word)
for the applicant to include in their project plans. (Help with downloading files.)
If the applicant incorporates the BMPs and other requirements of
the Tier 1 Checklist, the 404 permit can proceed with no further
review by the Texas Commission on Environmental Quality (TCEQ).
These BMPs and other requirement in the project will generally
result in substantial compliance with state water quality
standards. Certain rare and
ecologically significant wetlands are not eligible for the Tier
I processing and must be reviewed under the Tier II process.
