Gasoline Transport Dispensing Guide by olliegoblue36


									                                                   We designed this guide to help Georgia businesses understand
 An overview of Stage I/II                         and comply with environmental regulations concerning the
 rules for Georgia’s
                                                   transport and/or sale of gasoline. Environmental laws are not
small businesses.
                                                   designed to penalize small businesses. Rather they are written
                                                   to help create and maintain a healthy habitat for all of Georgia
                                                   citizens. Pollution affects the lives of millions of Georgians and
                                                   the environment in which they live. However, many Georgians

                                                   filling their automobile fuel tanks. Gasoline vapors combine with
                                                   other compounds in the air to form smog. In addition, gasoline
                                                   vapors contain many known cancer-causing agents. This
                                                   booklet will show in an understandable way how Georgians can
                                                   comply with Stage I and Stage II Vapor Recovery requirements.

                                                   WHAT IS STAGE I VAPOR RECOVERY?

                                                   Stage I Vapor Recovery refers to any system that is capable of
                                                   recovering the vapors generated when gasoline is being
                                                   transferred from a gasoline tank truck into a stationary storage
                                                   tank at a gasoline dispensing facility (GDF). The state of Georgia
                                                   requires that 90 percent of these vapors be reclaimed

                                                   The responsibility for complying with Stage I Vapor Recovery
                                                   requirements fall on both the transporter and the recipient of the
                                                   gasoline. Transporters of gasoline must have their equipment
                                                   pressure and vacuum tested once per year to ensure that there
                                                   are no leaks in the lines or in the dome cover gaskets on each
                                                   compartment. This includes the hoses, piping and connections.
                                                   The deliverer must also ensure that the equipment is properly
                                                   hooked up when transferring gasoline from the transport tank to
                                                   the storage tank.

                                                   A GDF is a site where over 10,000 gallons of gasoline per month
                                                   is dispensed to motor vehicles gasoline tanks from stationary
                                                   storage tanks. It must use one of the approved Stage I systems.
                                                   The systems approved by the Environmental Protection Division
                                                   are dual point and coaxial. These systems ensure the proper
                                                   displacement of vapors in the storage tank and their return to the
                                                   tank truck while gasoline is being transferred.

                                                   A dual-point connection is recommended where any mixture of
                                                   gasoline cannot be tolerated. It typically is the most expensive
                                                   and is easy to install at new sites. However, installation requires
                                                   some site excavation.

                                                   Coaxial connections are relatively inexpensive to install on
  October 1997                                     existing underground tanks because existing three-and four-inch
                                                   tank pipe lines can be converted to coaxial specifications (a pipe
                                                   within a pipe). Coaxial connections slow the delivery rate
                                                   because they reduce the size of the gasoline delivery pipe.
                       Therefore, more time will be required to fill a station's storage

Who Should have a Stage I System?

Operators of gasoline tank trucks, and gasoline dispensing facilities that operate in the
nonattainment area for ozone (Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas,
Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding, and Rockdale counties) and not
exempted by a Rule.


When is a Stage I System Required?

The Georgia Rules require that a Stage I Recovery System be installed and operating in
good condition before April 1, 1995 unless exempted by a rule.

Affected Equipment

Tank trucks that dispense gasoline.

Stationary storage tanks at GDF.

Hose and fittings used to return the storage tank vapors to the tank truck during filling
of the storage tank (vapor collection system).

Summary of Equipment Requirements

Stationary Storage Tank

A submerged fill pipe should be a nominal distance of 6 inches from the tank.

An approved vent at least 12 feet in height above the ground with a pressure/vacuum
vent valve with minimum setting of 8 ounces of pressure and I/2 ounce of vacuum;
unless the facility has a CARB certified Stage II Vapor Recovery System stating the
settings for the vent valve.

A Division approved leak tight vapor return system (hose and fittings) that connects the
storage tank being filled with gasoline to the gasoline tank truck.

Gasoline Tank Trucks

                       The tanks must be able to sustain a pressure change as
                 specified by the Division.

                        The owner of the truck must submit test data within 30 days of
                 the test date.

                        Pass annual leak tests by approved procedures.

                        Display on right front side of tank truck markings that read
                        either P/V TEST DATE or EPA27 and last test date in at least 2
                        inch high characters.

      The tank cannot have visible liquid leaks nor gasoline vapor leaks that can be
      detected by a combustible gas detector.

      Tank truck must be equipped with fittings that will automatically close when fill
      hose and return vapor hose are disconnected from the truck.


A facility in the nonattainment area that dispenses from a stationary storage tank 10,000
gallons or less a month of gasoline into motor vehicle gasoline tanks.

Stationary storage tanks of less than 2,000 gallon capacity and in place before January
1, 1979.

Stationary storage tanks of less than 250 gallons capacity and in place after December
31, 1978.

Stationary storage tanks with submerged fill pipes of less than 550 gallons capacity
and used exclusively for the fueling of gasoline tanks used in the husbandry industry.

Gasoline transport tank trucks that do not load or unload gasoline at bulk gasoline
terminals, bulk plants or GDF.


When you fill your car with gas, the vapors which are in the fuel tank are pushed out
into the atmosphere. Stage II captures these vapors and puts them back into the
underground storage tank (UST). The vapors trapped in the UST are then returned to
the tank truck when it comes to fill the USTs with gasoline. Stage I and Stage II work
together to form the entire vapor recovery system. The Stage II Vapor Recovery System

is designed to capture gasoline vapors that would escape into the air as vehicles are
being refueled.

In Georgia, the systems generally used are the balance system and the assist system.

The balance system operates by creating a sealed loop between a vehicle’s fuel tank
and the site storage tank. This requires a specialized nozzle which both dispenses fuel
and collects vapor. An outer cover or bellows surrounds the nozzle and forms a seal
with the opening to the vehicle’s tank. As gasoline is pumped into the vehicle, fumes
are displaced and flow into the bellows where they are collected and routed (pushed)
into the storage tank.

The assist system uses a vacuum that is mechanically generated to transfer vapors
from the vehicle fuel tank into the site storage tank. Although sometimes fitted with
bellows, this system’s nozzle does not necessarily rely on the bellows for proper
operation. Rather, the fumes are moved by turbines, electrical pumps or jets. Because
of this, there is no need for a tight seal between the nozzle and the vehicle’s tank

Who Should have a Stage II System?

Operators of GDF that operate in the nonattainment area and are not exempt by a rule.

When are you Required to Have Stage II Installed and Operating?

The Georgia Rules require that Stage II recovery equipment be installed and operating
properly at all affected dispensing facilities by November 15, 1995.

Summary of the Stage II Rule

An original certification test on the vapor recovery system is required to be completed
within 30 days and sent to the EPD.

A compliance report is due 12 months after the original certification test and is to be
sent to the EPD.

A compliance report is due annually after the initial compliance report and is to be sent
to the EPD.

A recertification test is due every five years from the date of the original certification or
upon a major system replacement or modification.

Facility is inspected annually by EPD’s Petroleum Industry Regulatory Team (PIRT).

Facility must have at least one employee that has received training and instruction on
the operation and maintenance of the recovery system installed at the facility where he
(she) works.

Specific pump operating instruction must be posted on the pump housing.

Maintain the recovery equipment in proper operating condition as specified by the


All GDF that dispense no more than 10,000 gallons of gasoline per month.

Any gasoline dispensing facility owned and operated by an “independent small
business marketer” (ISBM) of gasoline which was constructed or reconstructed before
November 15, 1995 that dispenses 50,000 gallons or less of gasoline per month. An
ISBM receives more than 50% of his income from the sale or marketing of gasoline.

Summary of Procedures for Maintaining Compliance for Stage I and II

Each gasoline dispensing site is required to:

      Provide training for employees in the use of the vapor recovery equipment

      Inspect and maintain the equipment

      Test equipment regularly in accordance with EPD schedules

      Keep throughput records for two years

      Keep Stage II test records for five years

      Owners/operators should visually inspect Stage II hardware every day

Additionally, owners and operators must perform dynamic back-pressure, liquid
blockage, and leak tests according to the requirements and schedules contained in the
Georgia Air Quality Rules.

Visual Inspection Procedures

The person performing the inspection should:

      Clear the vapor line by raising and extending the hose

      Look for and replace any slit bellows on Stage II system nozzles

      Make sure that at least 3/4 of the faceplate or cone of a bellows is intact to ensure
      proper seal

      Replace any torn, flattened or kinked hoses

      Remove any malfunctioning nozzle from

      Use only approved equipment for the

Record keeping Requirements

      Keep records of gasoline deliveries and

      Stage II systems test and training procedures

      Minutes of training meetings

      Delivery and inventory reports and financial records
