Automatic Tank Gauge (ATG) certification refers to the process of ensuring that automatic tank gauging systems used in fuel storage tanks are properly installed, maintained, and functioning according to regulatory standards. These systems are crucial for monitoring tank levels, detecting leaks, and preventing overfills, which helps in maintaining safety and compliance with environmental regulations.

In Texas, companies that operate aboveground storage tanks (ASTs) and underground storage tanks (USTs) are typically required to have their ATG systems certified. The certification process involves:

1. Installation Checks: Verifying that the ATG system is installed according to manufacturer specifications
and regulatory requirements.
2. Functionality Testing: Conducting tests to ensure the system accurately measures and reports tank
levels, detects any leaks, and provides reliable data for inventory control.
3. Maintenance Guidelines: Establishing a maintenance program to ensure the ATG system remains in
good working condition.
4. Training Requirements: Ensuring that personnel who operate and maintain the ATG systems are trained
and knowledgeable about their operation and the relevant regulations.
5. Documentation: Keeping detailed records of the certification process, any maintenance performed, and test results, which may be required for regulatory compliance inspections.

Certification helps to ensure environmental protection by minimizing the risks associated with fuel storage and ensuring compliance with federal and state regulations. If you are looking for specific details about ATG certification processes in Texas, it is advisable to consult the Texas Commission on Environmental Quality (TCEQ) or relevant local authorities.
