For tanks installed after April 11, 2016, is continuous in-tank monitoring an allowable form of release detection?

  1. Yes

  2. No

  3. Only with additional equipment

  4. Only if monitored by a third-party service

The correct answer is: No

Continuous in-tank monitoring is not an allowable form of release detection for underground storage tanks (USTs) installed after April 11, 2016. This is because regulatory standards put in place require more stringent and reliable methods of monitoring to ensure that any potential releases of hazardous substances are detected promptly. The regulations emphasize the need for more comprehensive detection methods that can effectively minimize environmental risks associated with USTs. Newer installations must typically adhere to enhanced requirements that incorporate various monitoring techniques, which may include interstitial monitoring, which provides a higher level of assurance against potential leaks. Continuous in-tank monitoring may not meet these updated compliance demands or offer the reliability that regulatory authorities are seeking. As a result, while continuous monitoring methods may be used in older systems or under certain conditions, for tanks installed after the specified date, the regulations specifically disallow it as a standalone method of release detection.
