TXR150000

TXR150000: The General Permit

TXR150000 is the Texas Pollutant Discharge Elimination System (TPDES) General Permit that governs the discharge of stormwater runoff associated with construction activities.

This permit sets forth the conditions and requirements that constructors must meet to discharge stormwater legally.

KEY POINTS:

  • Effective for 5 years, after which it must be renewed.
  • Addresses both small and large construction activities.
  • Requires the development and implementation of a Stormwater Pollution Prevention Plan (SWPPP).

Notice of Intent (NOI)

Submitting a Notice of Intent is the first formal step you’ll take to notify the Texas Commission on Environmental Quality (TCEQ) that you intend to discharge stormwater.

This document identifies key aspects of your construction project and outlines your commitment to adhering to state and federal water quality standards.

WHAT TO INCLUDE:

  • Project name and location
  • Operator details
  • Estimated timelines
  • Type of construction activity
  • Receiving waters information

Notice of Change (NOC)

Changes are inevitable in construction.

Should there be any significant alterations in your project that affect your discharge characteristics, you’ll need to file a Notice of Change with TCEQ.

This ensures that all data are up-to-date, and your project remains in compliance with the TXR150000 permit.

WHEN TO FILE:

  • Change in operator
  • Addition of new discharges
  • Modifications to construction plans affecting stormwater management

Notice of Termination (NOT)

Once your project is complete, and all land-disturbing activities have ceased, you’ll need to submit a Notice of Termination.

This informs the TCEQ that you no longer require coverage under the TXR150000 permit.

PREREQUISITE:

  • Final stabilization of the construction site
  • No further need for stormwater discharge
  • All temporary measures removed or made permanent

Wrap Up

Understanding the NOI, NOC, NOT, and the TXR150000 General Permit is vital for ensuring your construction project complies with Texas’s environmental regulations.

While the process may seem complicated, each step provides a structured approach to manage stormwater discharges effectively, protecting both your project and the environment.
