Underground Gasoline Storage Tanks and Enhancements to Gasoline Dispensers
January 17, 2005
Like an Energizer battery, California regulations on the environment keep on goin and goin and goin. The state of California has enacted new environmental regulations for underground storage tanks for gasoline and related dispensers. By April 1, 2005, all gasoline facilities dispensing with underground storage tanks will have to make significant equipment upgrades costing typically in the range of $8,000-10,000 (depending upon your current system). Briefly, the requirements are as follows:
The local AQMD will require submission of permit application for all major modifications to the dispenser equipment or the vapor recovery system. For all the facilities with aboveground tank(s) for gasoline, the nozzle dispenser rules and the tank vent system rules apply as well. It will be difficult, if not impossible, for the average facility manager to discern the current level of compliance. Hence, it is imperative that the facility contacts a licensed contractor (ICC Certified) in the field to determine the level of upgrades required and the associated costs.
ALL YOU WANTED TO KNOW ABOUT DISPENSERS AND NOZZLES BUT WERE AFRAID TO ASK
1. What are considered Major Modifications? Major Modification is defined as:
2. What happens if I don’t meet the April 1, 2005 deadline?
The owner/operator of the GDF will be in violation of State law and AQMD Rule 461. Penalties of $40,000/day or more, Order of Abatement, and court injunctions can be imposed on a GDF if found to be in non-compliance.
3. What kind of Phase I EVR systems can I install at my facility?
Only California Air Resources Board (CARB) certified equipment could be installed, so your choice must be an approved system. Currently there are four systems available that are CARB certified:
4. Are there any additional or specific vapor recovery performance tests required with EVR systems?
Yes. Your certified Tester should be familiar with the appropriate test for each system. These tests are:
5. What is ORVR?
ORVR stands for Onboard Refueling Vapor Recovery. This refers to the vapor collecting devices on some late model (1998 or newer) passenger vehicles. ORVR systems are not compatible with some existing Phase II vacuum assist vapor recovery systems and this has been found to lead to excess emissions at the GDF.
6. What system can I install that are ORVR compatible and CARB certified?
The following system is currently ORVR compatible and CARB certified:
7. What is nozzle liquid retention?
This is the amount of gasoline remaining in a nozzle spout per 1000 gallons of gasoline dispensed. It is a measure of how a nozzle can minimize vapor emissions. Nozzles that currently meet this requirement are listed under Executive Order G-70-199-AI. Please refer to CARB web site (www.arb.ca.gov/vapor/vapor) for more information.
8. How do I begin to update my system to meet CARB Phase I EVR and Phase II ORVR requirements?
