Locate fill pipe such that the delivery operator can perform tank fueling without climbing or walking on tank.

Means shall be provided to prevent overfilling by sounding an alarm when the liquid level in the tank reaches 90 percent of capacity and by automatically stopping the delivery to the tank when the liquid level in the tank reaches 95 percent of capacity. Overfill prevention equipment must not interfere with the proper operation of either normal or emergency tank vents.

Fill pipes that enter the top of the tank shall terminate within six (6) inches of the bottom of the tank.

All tanks storing flammable liquids shall have a drop tube installed on the fill line that terminates within six (6) inches of the bottom of the tank.

Fill lines shall not drop below the top of the tank, unless they are connected to a remote fill assembly.

All tank-top fill connections shall be made within a spill catchment basin.

All fill lines on aboveground storage tanks shall be fitted with a quick-connect adaptor that provides a positive locking connection between the delivery hose and fill connection.

10.4.6 Fill Lines


Design Criteria


10. All fill lines shall have a liquid-tight cap, which shall be properly identified, closed, and/or locked when not in use.

11. Means shall be provided to determine the level of liquid in the tank. This means shall be accessible to the delivery operator.

10.4.7 Remote Fill Assemblies

1. In the event a remote fill assembly is required, it shall be installed in a convenient grade-level access to the tank delivery point.

2. The remote fill assembly shall consist of a liquid-tight spill container capable of contacting any drips or spill that occur during the fuel delivery process. A manual pump or other means shall be provided to transfer any released product back into the tank. A manual drain must also be located in the bottom of the remote fill assembly to permit manual draining of liquids, if necessary.

3.4. The delivery hose connection must be positioned so that that is maintained at a

lower elevation than the discharge hose on the delivery truck.

5. The delivery hose connection point shall be equipped with a quick-connect adaptor, check valve (to prevent backflow), and a block valve / ball valve. If space is limited, the check valve and block valve may be located outside the spill container, but must be as close to the quick-connect adaptor as possible.

10.4.8 Collision Protection

1. Where a tank, piping, or dispensing unit might be exposed to vehicular impact, protection shall be provided to prevent damage to the equipment.

2. For all permanent aboveground storage tanks, pipe bollards shall be provided around all sides of tank from which traffic could possibly approach. Space bollards at intervals not greater than four (4) feet on center. Pipe bollards shall be installed in accordance with NFPA 30A, section 4.3.7.2.

3. Dispensing devices shall be mounted on a concrete island or shall be otherwise protected against collision damage.

4. For aboveground piping installed near roof lines, piping shall be protected from damage caused by falling ice.

10.5 STORAGE TANKS ASSOCIATED WITH GASOLINE DISPENSING/MOTOR VEHICLE REFUELING FACILITIES (GD/MVRFS)

Please see Chapter 4.8 titled “Environmental Coordination,” Section 4.8.5 regarding the Gasoline Dispensing/Motor Vehicle Refueling Facilities Permitting Process and Design Requirements.

For the purposes of this section and all subsequent subsections, “Owner” refers to the Maryland Aviation Administration (MAA), or either of BWI Marshall and/or Martin State Airports as determined by the context. “Designer” refers to any entity commissioned to design and/or specify equipment described herein for construction and/or installation at any MAA facility or location within the BWI Marshall and/or Martin State Airports.

Owner must ensure that proper procedures are followed during product transfer from cargo tanks to storage tanks to minimize vapor releases, such as minimizing gasoline spills, expeditiously cleaning up gasoline spills, using gasketed seals for gasoline containers and storage tank fill pipes, and minimizing product being sent to open waste collection systems that collect and transport gasoline to reclamation and recycling devices such as oil/water separators. Owner must not permit cargo (delivery) trucks/tanks to unload gasoline into a storage tank unless proper connections in the vapor balance system are established, vapor-tight equipment and connections are used, and the tank truck vapor return equipment/hatches/seals are vapor- tight and compatible with the storage tank vapor balance equipment. Additionally, the cargo tank must carry documentation that it has met specifications of EPA method 27.

Owner must comply with general requirements pertaining to permit duration, availability of permit at permitted location, modifications, inspections, right of entry, violations, and penalties as outlined in Part III of MDE/ARMA’s Air Quality General Permit to Construct Application Package fo r Motor Vehicle Refueling Facilities.

In addition, the following recordkeeping, testing, notification, and reporting procedures are required for GD/MVRF storage tanks:

1. Recordkeeping

a) For tanks with a monthly throughput of less than 100,000 gallons and Stage I vapor recovery equipment, owner must make gasoline throughput, gasoline spills and cleanups, and maintenance records available within 24 hours of a Maryland Department of the Environment’s Air and Radiation Management Administration (MDE/ARMA) request.

b) For tanks with monthly throughput of 100,000 gallons or more and Stage I vapor recovery equipment, owner must make those records outlined in item l.a., above, as well as records of all tests performed and all notifications or reports submitted to the EPA or MDE/ARMA available within 24 hours of a MDE/ARMA request.

c) All records must be kept by owner for a period of five years.


Design Criteria


d) Additional recordkeeping requirements are outlined for tanks with Stage II vapor recovery equipment (required for all new sources at BWI Marshall and Martin State Airports) in Part II, Section E(2) of MDE/ARMA’s Air Quality General Permit to Construct Application Package fo r Motor Vehicle Refueling Facilities.

2. Testing

a) For tanks with a monthly throughput of 100,000 gallons or more and Stage I vapor recovery equipment, owner must demonstrate compliance at the time of installation and every three years thereafter with those tests outlined in Section 4.8.5.2, subsection 5(d-g) and in Part II, Section B(l)(c) of MDE/ARMA’s Air Quality General Permit to Construct Application Package fo r Motor Vehicle Refueling Facilities.

b) Testing frequency as well as additional testing requirements for tanks with Stage II vapor recovery equipment are outlined in Part II, Section B(2) of the Application Package.

c) Owner must ensure that all Stage II equipment is inspected at least daily, and that at least one employee shall be trained to conduct inspections through an approved training course.

3. Notifications

a) Regulatory notifications are required for tanks with monthly throughput of 10,000 gallons or more and Stage I vapor recovery equipment. Notification types include Initial, Compliance, Change in Information, and Performance Test, and requirements increase for tanks with a monthly throughput of 100,000 gallons or more. These notification requirements and procedures are outlined in Part II, Section C of the Application Package.

b) Except for Performance Test notifications, there are no other notification requirements for tanks of any size with Stage II vapor recovery equipment (see Part II, Section C(2) and Section D(2) of the Application Package). Owner must notify MDE/ARMA of any Stage II vapor recovery equipment performance tests at least 5 days before conducting the test. Copies of all test results and reports of test failures must be forwarded to MDE/ARMA within 45 days per Part II, Section D(2) of the Application Package.

4. Reporting

a) There are no reporting requirements for tanks with monthly throughput of less than 100,000 gallons and Stage I vapor recovery equipment. For tanks with monthly throughput of 100,000 gallons or more and Stage I vapor recovery equipment,
