The Comptroller's Office routinely tests the quality of motor fuels sold in Maryland. If you have a question or complaint about fuel quality, call 410-260-7388.

Maryland's testing program checks fuel quality at all points along the distribution chain, and stops the sale of fuel that does not meet accepted quality standards. The comptroller maintains a petroleum testing laboratory, which is consistently recognized as a leader in its field. Samples representing about two billion gallons of gasoline, diesel fuel, home heating oil, and other fuels are tested each year. Only about 1 percent of the fuel tested is found to be substandard.

The Inspection Program is comprised of Enforcement Agents and Compliance Inspectors who work as a team in their efforts to enforce and regulate the revenue laws involving alcoholic beverages, motor fuels, tobacco products, transient vendors and vendors at flea markets and other venues. Samples of the various grades of motor fuels sold in the state are collected daily to assure their compliance with state and federal regulations, as well as to assure that applicable taxes have been paid. Any substandard product is removed from the marketplace until the problem is corrected.

The transportation and storage of motor fuels is constantly monitored to verify that regulations governing pricing, labeling and registration are being followed. Investigations are conducted to identify and locate unlicensed fuel sellers, unregistered IFTA motor carriers and users who illegally use untaxed dyed fuel in highway vehicles.

Licensed alcoholic beverage retailers are likewise inspected to confirm their compliance with related laws, including efforts to defraud customers by altering the contents of more expensive beverages with less expensive brands while selling these products at the higher price. Investigations of unlicensed sellers are conducted across the state, resulting in arrests and confiscations of illegally sold items.

The sale of tobacco products are also monitored, with inspections of licensed establishments, as well as investigations of unlicensed sellers which result in arrest and confiscation of the items sold illegally (either without a license, or involving contraband untaxed cigarettes).

In addition, as mentioned, the agents and inspectors constantly look for unlicensed Transient Vendors, such as those selling furniture along our roadsides without licenses and not collecting related taxes, as well as vendors at sporting events and at flea markets who likewise do not possess the proper licenses and do not collect or remit related taxes.

The Field Enforcement Bureau of the Comptroller of Maryland's Office is responsible for checking the quality of petroleum products sold in Maryland. Motor fuel inspectors cover every region of the state. They enforce provisions regulating containers and vehicles used to transport and store all motor fuels, signs advertising prices for gasoline and special fuels, and waterborne movements of motor fuels - interstate, intrastate and/or all points of the supply chain, from terminal or ship to bulk plant, to distributor, to retail service station.

At retail service stations, the inspector will look for the price posted, brand identification, pump price display, pump decals that show octane ratings, color coded fills, the four most recent delivery tickets, registration certificate and any appropriate special fuels tax exemption certificate. The inspector will draw and pay for each grade of product to be tested at the Comptroller's petroleum testing lab in Jessup, although some tests are conducted on site.

The inspector will want to see the trader's license and retail sales tax license for the business, and will inspect all cigarette inventory for proper stamps as well as reviewing all delivery invoices for cigarettes, other tobacco products and alcoholic beverages.

At bulk locations

The inspectors will check the vehicles for Department of Transportation markers, compartments, loading documents, transfer documents, name on tanks and color coding.

On The Spot Tests

On site testing includes tests for water and sediment in storage tanks, and a screening for octane.

Testing At The Lab

Once initial tests are done, samples are taken to the comptroller's petroleum testing lab. Samples are chilled before testing to preserve the integrity of the testing process. The testing lab conducts quality control tests to make sure petroleum products meet Maryland specifications. Routine tests include vapor pressure, distillation, octane ratings, water and sediment, oxygen content and percentage and type of oxygenate, if any, in gasoline.

Special fuels

Fuel oils, diesel fuels and kerosene are tested for flash point, distillation, sulphur content, API gravity, and, if applicable, viscosity, color and cetane index or cetane number.

Sample locations are randomly selected for analysis. The laboratory participates in national and regional exchange groups as part of its quality assurance program.

The inspector will leave a warning, noting the problem discovered and the time permitted to correct the problem.

The lab targets for a 24-hour turnaround. If a sample fails a test, a field inspector is immediately dispatched to issue a "stop sale" order for the fuel that does not meet specifications. The "stop sale" will be removed when the problem is corrected. Inspectors work with the distributor to discover the source and correct the problem.

We will tell you the problem with the fuel. You must contact the supplier to find out if the problem is correctable on site or if the product must be removed. You must contact the Field Enforcement Bureau at 410-260-7388 to discuss the proposed remedy. Once you receive authorization and the remedy is performed, contact us and we will re-sample the product promptly.

No. It's illegal to sell motor fuel that fails to meet quality standards. Penalties for not complying with the motor fuel inspection law and the stop sale order include a fine of up to $5,000 and/or one year in jail, a court ordered injunction prohibiting sale of the product and suspension of your registration.

The Comptroller's Motor Fuel Testing Lab in Jessup, Maryland began operation in 1974. The primary function of the lab is to analyze all incoming petroleum products for their quality and to make sure the fuel is in compliance with state regulations, as well as federal EPA guidelines. The laboratory is also equipped to run analysis of alcoholic beverages for proof verification using Gas Chromatography procedures. Gasoline and petroleum products are collected at the retail stations and bulk terminals throughout the state by the Comptroller's compliance inspectors also take monthly samples from bulk terminals at nearby Virginia and Pennsylvania locations, as fuels from these locations regularly enter the Maryland market.

The Comptroller's Enforcement Program, is staffed with Enforcement Agents who are sworn police officers. The agents work individual investigations and also joint cases with inspectors. Enforcement Agents are charged with investigating violations of state revenue laws pertaining to tobacco, trader's and transient vendors license, sales and use tax, alcoholic beverage violations and IFTA and motor fuel violations.

Investigations conducted by the agents may result in a physical arrest or the violator receiving a criminal citation. FED Agents also work closely with other state law enforcement agencies and Federal law enforcement agencies such as, ATF, FBI, and Immigrations and Customs Enforcement, to monitor and arrest individuals that live in the state and individuals that live outside the state who enter Maryland to commit revenue crimes.

The agents pay special attention to large organized groups that ship contraband or counterfeit cigarettes and alcohol into the State in violation of state laws. Agents fan out across the state visiting retail businesses to ensure they are properly licensed and in compliance with state record keeping laws. Enforcement agents are constantly on the lookout for Transient Vendors that set up business on the side of the road or in parking lots. Since many of these vendors work without proper licenses, they are checked when they are observed, to ensure they comply with all State and County laws and requirements.

Agents routinely meet with business owners that have failed to pay the state, sales and use taxes they have collected. They meet with these individual businesses in an effort to collect monies owed the state.

By enforcing state laws and regulations that pertain to license and taxes the Enforcement Program the Comptroller's Office works hard to ensure a level playing field for all citizens and retail businesses in the state of Maryland.
