Preliminary Rulemaking Activity
- Revising the in-station diagnostics (ISD) system overpressure alarm criteria, improving and clarifying ISD report content, and providing more options for ISD communication ports, such as USB or Bluetooth, in addition to the currently required RS232 port;
- Making the nozzle spillage standard more stringent to preserve superior performance achieved by currently certified equipment, and avoid backsliding;
- Revising Phase I drop tube compliance test procedures to allow for remote fill configurations for gas stations equipped with underground storage tanks;
- Requiring vapor recovery equipment manufacturers to provide physical samples of the system or components that successfully comply with applicable performance standards or specifications; and
- Various administrative changes to clarify and improve the certification and test procedures for better regulatory certainty and enforceability.
