Vapor Recovery 101

Stage I Vapor Recovery is the capture and control of gasoline vapors that would normally be released into the atmosphere during the storage of gasoline at a terminal or bulk plant or during the loading of a gasoline delivery vessel and the subsequent delivery and unloading of a gasoline delivery vessel into another storage tank, usually at a Gasoline Dispensing Facility, or GDF.

Stage II Vapor Recovery is the capture and control of gasoline vapors that would normally be released into the atmosphere during the refueling of motor vehicles at a GDF. When you refill your automobile gas tank, the fresh gas forces out the vapors left in the tank from the last tankful into the atmosphere. Stage II Vapor Recovery, recognized by the black boots on the gasoline nozzles at St. Louis area stations, captures the vapors from the automobile tank and returns these vapors to the underground storage tank at the GDF. Infared demonstrations of fuel vapors escaping are available online. The storage tank holds the vapors until a gasoline delivery vessel using Stage I Vapor Recovery refills the tank. These vapors are then returned, by way of the gasoline delivery vessel, back to the terminal for processing or destruction. Currently only Balance Vapor Recovery systems are approved in Missouri. Diagrams of both systems are available online.

Areas Required to Maintain Vapor Recovery Systems

Stage I and Stage II Vapor Recovery are required by Missouri Regulation 10 CSR 10-5.220, "Control of Petroleum Liquid Storage, Loading and Transfer,"and are required in the St. Louis Ozone Maintenance Area. This area includes St. Louis City, St. Louis County, St. Charles County, Franklin County and Jefferson County.

Stage I Vapor Recovery, required by Missouri Regulation 10 CSR 10-2.260, "Control of Petroleum Liquid Storage, Loading and Transfer," is currently used in the Kansas City Ozone Maintenance Area. This area includes Kansas City, Jackson County, Platte County and Clay County. For more information on these regulations see the Code of State Regulations.

A nonattainment area is an area that has failed to attain the health-based National Ambient Air Quality Standards or NAAQS set by EPA for certain air pollutants, in this case ground-level ozone. In comparison, a maintenance area is an area that records air pollutant concentrations at levels at or near the health-based standard and the air quality must be maintained to ensure that the area stays in attainment for the ozone standard. EPA requires the state to develop a maintenance plan for the area as well. This plan outlines what actions the area will take to stay in compliance with ground-level ozone standards. For more information visit www.epa.gov/airprogm/oar/oaqps/gooduphigh/.

Vapor Recovery is also required in several outstate areas due to recent promulgation of federal Maximum Achievable Control Technology standards. For more information on these requirements see subparts 6B and 6C on the Area Source Standard page.

Other state and federal regulations may also apply to your facility. For more information on any additional regulations contact the Missouri Department of Agriculture's Division of Petroleum Quality and Inspection at 573-751-4278 for state safety regulations and Hazardous Waste Program's Tanks Unit for Underground Storage Tank regulations at 573-751-3176. Further information can also be obtained from the Hazardous Waste Program's newsletter Tank Wise.

The Stage I and Stage II Vapor Recovery programs in St. Louis and the Stage I Vapor Recovery program in Kansas City have been very effective in reducing gasoline vapor emissions. These emissions are a type of volatile organic compound. These compounds, in combination with nitrogen oxide compounds or NOx and sunlight, contribute to the formation of ground-level ozone. The department is committed to improving the effectiveness of these volatile organic compound control programs. Over the years, the department has developed these programs to control gasoline emissions. Improvements include:

By conducting MOPETP testing on vapor recovery systems and components we have increased our knowledge of vapor recovery systems that work and systems that need improvement. We have protected the majority of our GDF owners from purchasing expensive vapor recovery systems that fail to meet efficiency and durability requirements (e.g.. vapor assist systems). Vapor assist systems seemed innovative early in the history of vapor recovery, but later were found to be ineffective and in need of costly improvements. The department has been instrumental in discovering problems with individual components and component systems. The MOPETP process provides the department with the data and experience needed to help ensure that the vapor recovery systems purchased by the retail GDF owners meet efficiency and durability requirements.

Missouri Performance Evaluation Testing Procedures

The department established the MOPETP program to ensure the efficiency and overall performance of vapor recovery systems and equipment installed in Missouri. The California Air Resources Board or CARB certifies vapor recovery equipment under California's climatic conditions. In contrast to California’s steady climate, Missouri’s varying climatic conditions require further testing to ensure that vapor recovery systems and equipment will function properly throughout the seasons.

The MOPETP is a bank of individual test procedures that apply to manufacturers of vapor recovery systems and components. The department uses these test procedures to evaluate the overall efficiency and performance of the various types of gasoline vapor recovery equipment and systems. Gasoline delivery facilities or GDFs use these systems to control the emission of gasoline vapors during the fueling of automobiles and during gasoline deliveries. Only vapor recovery systems and components with CARB certification and current MOPETP approval can be used by GDFs in the St. Louis nonattainment area.

The Technical Review Committee is a creation of MOPETP. The intent of the this committee is to provide a panel of qualified experts to listen to the requests of vapor recovery system and component manufacturers and petroleum equipment contractors. The panel collects information and advises the staff director on technical decisions involving the applicability of the various tests needed to demonstrate compliance with Missouri requirements for control efficiency. The Technical Review Committee is comprised of representatives from various air pollution control agencies, vapor recovery equipment manufacturers and other interesting parties from within the St. Louis area. Currently, committee meetings are announced via the Vapor Recovery listserv and all interested parties are invited to attend.

Permit Application Timeline
GDF owners or operators in the St. Louis nonattainment area should apply for a permit to construct at least 60 days before beginning construction. The application should include:

Construction permits applications may be obtained by contacting the appropriate air pollution control agency above. GDFs must display the permit to construct in a prominent location on-site during construction. GDFs must also notify the appropriate air pollution control agency seven calendar days before the anticipated completion of the underground piping in order to schedule an inspection date. GDFs must not cover underground piping before local air pollution control agency staff inspects it. GDFs must conduct and pass final leak decay tests, dynamic back pressure/liquid blockage tests and stet valve bench tests within 30 days of completion of construction. GDFs must then obtain a current operating permit and maintain it on-site in a prominent location.

Note icon. This is a limited summation of the requirements. See 10 CSR 10-5.220 for all applicable regulations concerning construction and operating permits for GDFs in the St. Louis nonattainment area.

Gasoline Bulk Loading Plant Requirements

Stage I Vapor Recovery Requirements for Gasoline Bulk Loading Plants
Both the Kansas City and St. Louis area regulations require Stage I Vapor Recovery on the storage tanks and the delivery vessels that transfer gasoline into them. Bulk plants must have Stage I Vapor Recovery on loading racks and delivery vessels that deliver fuel to customers as well. Gasoline delivery vessels are also required to have a valid annual Missouri tank tightness sticker. This sticker is obtained by submitting an annual tank tightness sticker application (U.S. EPA Method 27 Tank Tightness Test - Pressure/Vacuum Test Certification Application) to the Air Pollution Control Program.

Note icon.If the bulk plant has an average monthly throughput of less than 120,000 gallons per month, the plant can apply for a Low Throughput Exemption from the requirement for Stage I Vapor Recovery on its loading rack and outgoing delivery vessels. This exemption does not apply to the incoming delivery vessels or to the vapor recovery on its storage tanks.

The application for a Low Throughput Exemption must be completed and arrive at the Missouri Department of Natural Resources' Air Pollution Control Program, P.O. Box 176, Jefferson City, MO 65102, before February 1 of each year.

Compliance Testing and Inspection Requirements

St. Louis Vapor Recovery Compliance Requirements
GDFs must conduct a pressure leak decay test, p/v valve bench test and either a backpressure blockage test or an Air/Liquid (A/L) test depending on the type of vapor recovery system employed. This testing is required when a GDF renews its operating permit (every five years) and at the completion of any construction on the facility. The vapor recovery system used by the GDF must have current CARB certification and be MOPETP approved.

Kansas City Vapor Recovery Compliance Requirements
GDFs must conduct an initial pressure leak decay test and p/v valve bench test. Thereafter, the GDF must complete a pressure leak decay test once every five years and a p/v valve bench test once every two years.

Vapor Recovery Systems or Components Certification in Missouri
All vapor recovery systems and components installed in Missouri must be first CARB-certified and then MOPETP-approved.

Vapor Recovery System Inspections and Tag Out Procedures
The department and local air pollution control agency staff inspect Stage II vapor recovery GDFs twice a year. These inspections look for defective equipment, required permits and general compliance with Stage I and Stage II vapor recovery regulations. If defects are found that would significantly affect the efficiency of the vapor recovery system, the GDF is issued a Notice of Violation for the defects and the equipment will be "tagged out" of service by the inspector. If GDF equipment is tagged out, the station owner or operator needs to immediately repair or replace the defective equipment. Once repairs or replacements are complete, the station owner or operator should contact the department or appropriate local agency to re-inspect. Inspectors must re-inspect and remove “tag outs” before the equipment can be put into service. It is the GDF owner or operator's responsibility to ensure the defective equipment remains “tagged out” until cleared by the department or local agency inspector.  If the GDF allows dispensing from the tagged out equipment prior to re-inspection, the department may pursue further enforcement action, including monetary penalties, in order to penalize the GDF for this illegal dispensing. Generally, the department does not pursue monetary penalties for Notices of Violation issued for defective equipment unless this illegal dispensing occurs. However, there are certain violations which automatically trigger monetary penalties, such as the use of unapproved equipment, or failure to apply for or comply with a construction or operating permit. Depending on the location of the GDF one of the following offices should be contacted for reinspection:

Enforcement Memos and Guides

Gasoline Delivery Vessel Requirements

Due to budget constraints, the Missouri Department of Natural Resources’ Air Pollution Control Program will temporarily cease the issuance of Missouri tank tightness certifications until further notice. This change is effective immediately and applies statewide to all affected facilities and companies. Please note, a copy of the vessel’s current Tank Truck Tightness Test results (tested in accordance with 40 CFR Part 63, Subpart R, Section 63.425(e)) is still required to be kept with the delivery vessel at all times and made immediately available to the department upon request. We thank you for your patience and cooperation.

Stage I Vapor Recovery Requirements for Gasoline Delivery Vessels
If the owner or operator of a gasoline delivery vessel wishes to operate a gasoline delivery vessel that is loaded or unloaded in the St. Louis or Kansas City ozone maintenance areas, the delivery vessel must be equipped with proper Stage I Vapor Recovery. Further, if the gasoline delivery vessel loads at a bulk plant or terminal regulated by 40 CFR Part 60, Subpart XX or Part 63, Subpart R, the vessel must be equipped with Stage I Vapor Recovery. Also, all gasoline delivery vessels operating in the St. Louis or Kansas City ozone maintenance areas must have a valid tank tightness sticker for Missouri. Tank tightness stickers are attached to delivery vessels and provide proof that the gasoline delivery vessel has passed all necessary Federal Testing Regulations concerning gasoline delivery vessels equipped with Stage I Vapor Recovery. The APCP issues tank tightness stickers. See testing requirements below for further information on tank tightness stickers.

Testing Requirements for Gasoline Delivery Vessels
Gasoline delivery vessels that operate in the St. Louis and Kansas City ozone maintenance areas are required to test annually to demonstrate compliance with the test method specified in 40 CFR Part 63, Subpart R, Section 63.425(e). Once a gasoline delivery vessel successfully passes annual testing, the owner or operator of the vessel must submit the results to the department's Air Program on the Delivery Vessel Pressure Test Certification Application, Form--MO 780-1262. The Air Program will review the application and will issue a sticker.

Note: Missouri also accepts pressure/vacuum test certificate application from other states as long as that state uses method 27 as the standard. However, the delivery vessel must still have a Missouri sticker.

Illegal Drops and Enforcement Actions
An illegal drop is when a gasoline delivery vessel unloads gasoline at a GDF inside the St. Louis or Kansas City Ozone Maintenance Areas without properly using Stage I Vapor Recovery. Drivers must use one vapor return line per gasoline product line during Stage I Vapor Recovery bulk gasoline deliveries. Vapor return lines must be no smaller than three inches in inside diameter and product lines must be no larger than four inches in inside diameter.

The department will take enforcement against gasoline delivery company drivers that fail to properly use Stage I Vapor Recovery when unloading gasoline at a GDF. Gasoline delivery vessel drivers and GDF owner or operators may also be held responsible for illegal drop violations and enforcement action may be taken. Enforcement actions will also be taken for failure to have method 27, method 27 paperwork and a Missouri sticker on the truck.
