Gasoline Dispensing Facilities

40 CFR 63 Subpart CCCCCC covers all facilities that dispense gasoline into:

on- and off-road street or highway motor vehicles
lawn equipment
boats
test engines
landscaping equipment
generators
pumps
other gasoline-fueled engines and equipment

The requirements under this rule are based on average monthly throughput and are broken up into three tiers:

Less than 10,000 gallons monthly throughput;
Between 10,000 and 100,000 gallons;
Greater than 100,000 gallons monthly throughput.

Control Requirements

Control requirements under this regulation are:

Monthly Throughput *	Requirements
Under 10,000 gallons Between 10,000 and 100,000 gallons Greater than 100,000 gallons	Minimize spills Clean up spills expeditiously Cover gasoline containers & storage tank fill pipes with gasket seal Minimize gasoline sent to open collection systems All of the above, plus: For storage tanks greater than 250 gallons capacity, load storage tank using submerged fill with discharge that is no more than the following from the bottom of the tank: 12 inches for pipes installed on or before 11/9/2006 6 inches for pipes installed after 11/9/2006 All of the above, plus one of the following:** Operate vapor balance system during storage tank loadings using the follow management practices Equipment connections & lines with seal closures Vapor tight line from storage tank to cargo tank Cargo Tank pressure remains below specified settings Designed to prevent over tight/loose fittings Gauge well provided with submerged drop tube extending specified distance from tank bottom, in keeping with Item 5, above Use vapor tight caps for liquid fill connections Install pressure/vacuum vent valves on tank vent at specified setting, and test initially and every 3 years Vapor balance system must meet static pressure test initially and every 3 years Dual-point (no coaxial) vapor balance systems for new GDF or tanks, and reconstructed GDF Vapor balance system demonstrated to achieve a reduction of 95% or better.

Monthly Throughput *

Requirements

Under 10,000 gallons

Between 10,000 and 100,000 gallons

Greater than 100,000 gallons

Minimize spills
Clean up spills expeditiously
Cover gasoline containers & storage tank fill pipes with gasket seal
Minimize gasoline sent to open collection systems

All of the above, plus:
For storage tanks greater than 250 gallons capacity, load storage tank using submerged fill with discharge that is no more than the following from the bottom of the tank: **

12 inches for pipes installed on or before 11/9/2006

6 inches for pipes installed after 11/9/2006

All of the above, plus one of the following:

Operate vapor balance system during storage tank loadings using the follow management practices

Equipment connections & lines with seal closures
Vapor tight line from storage tank to cargo tank
Cargo Tank pressure remains below specified settings
Designed to prevent over tight/loose fittings
Gauge well provided with submerged drop tube extending specified distance from tank bottom, in keeping with Item 5, above
Use vapor tight caps for liquid fill connections
Install pressure/vacuum vent valves on tank vent at specified setting, and test initially and every 3 years
Vapor balance system must meet static pressure test initially and every 3 years
Dual-point (no coaxial) vapor balance systems for new GDF or tanks, and reconstructed GDF

Vapor balance system demonstrated to achieve a reduction of 95% or better.

* - Monthly throughput is defined as either the total volume of gasoline loaded into or dispensed from all storage tanks at a GDF each month. It is calculated by summing the total gasoline loaded into or dispensed from all storage tanks each day with the previous 364 days, then dividing by 12.

** - Facilities complying with Nebraska Fire Marshal Underground Storage Tank regulations are already in compliance with this regulation.

Compliance Dates:

Existing Facilities	January 10, 2011
New Facilities	At startup
Facilities that dispense gasoline into tanks other than those in motor vehicles	January 24, 2011

Reporting Requirements

While 40 CFR 63 Subpart CCCCCC requires initial notification and notification of compliance only for those facilities with monthly throughput over 100,000 gallons (since facilities in Nebraska dispensing between 10,000 and 100,000 gallons are already complying with the State Fire Marshal requirements for submerged filling and are thus exempt from notification requirements), the City of Omaha requires all facilities subject to this rule to submit notifications.

Notification Schedule:

Notification Type	Due Date
Initial Notification	Existing Facilities: May 9, 2008 New Facilities: Within 15 days of startup Facilities that load gasoline into tanks other than those in motor vehicles: May 24, 2011
Notification of Compliance	Existing Facilities: March 11, 2011 New Facilities: 60 Days after startup Facilities that load gasoline into tanks other than those in motor vehicles: January 24, 2014
OAQC Annual Notification of Compliance	March 31st of each year
Other Notifications	Vapor Balance Test: 60 days prior to test Vapor Balance Test Results: 180 days after test

For further explanation of the requirements in this rule, please watch this EPA produced video. Please do note that the City of Omaha has notification requirements that differ from those stated in the video (see above).
