A university employee posts a warning sign by Strawberry Creek after a diesel fuel spill closed…

BERKELEY — Emergency crews from five different agencies spent Sunday cleaning up a diesel fuel leak that closed UC Berkeley’s Stanley Hall and seeped into nearby Strawberry Creek.

A pump valve failure for a diesel fuel storage tank for an emergency generator in the basement of Stanley Hall is being blamed for 1,700 gallons of fuel leaking into the basement and eventually into Strawberry Creek and the San Francisco Bay, according to university spokeswoman Janet Gilmore.

A campus police officer noticed an odor of diesel fuel coming from Strawberry Creek around 7 p.m. Saturday, Gilmore said. After an investigation, employees from the Office of Environment, Health and Safety discovered the leak and closed the building, which is the largest research building on campus and home to the university’s bioengineering department.

The leak was contained by 9 p.m. Saturday but an unspecified amount of fuel seeped into Strawberry Creek through pumps in the basement of Stanley Hall.

The emergency generator tank needs to constantly hold enough gas to power the building for 24 hours should there be an emergency, Gilmore said. It’s regularly tested to be sure it’s working, and as those tests use fuel, a dedicated storage tank sends the generator a top-off.

If the tank was equipped with our simple Overfill Alarm, this spill would have been detected sooner or possibly avoided altogether.  A 110 DB alarm would have signaled a problem, and helped to bring attention to the equipment failure.

According to the New York State Department of Environmental Conservation, 400 gallons of chemicals spilled last week at the Crowley Foods plant in LaFargeville.

No chemicals were released into the environment.

The DEC said it received a report of the spill on December 2.

The following materials leaked:

- Sodium Hydroxide
- Sulfuric Acid
- Nitric Acid

The DEC said two doublewall aboveground storage tanks leaked their chemical product into the secondary containment of their respective tank.

Plant personnel plan to pump product back into the original tanks, use the chemical up, then replace the tanks, the DEC said.

Above Ground Tank Installation- NFPA 30- Tank Storage

The following PDF is the NFPA Code for above ground storage tank (AST) installation.

Above-Ground-Tank-Installation-Relevant-NFPA-Code

On page 4, Section 4.3.2.3.3, letter C the code states the following:

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 delivery of liquid to the tank when the liquid level in the tank reaches 95 percent of capacity. In no case shall these provisions restrict or interfere with the proper functioning of the normal vent or the emergency vent

Our Overfill alarms, when mounted to our standard liquid level gauge (Therma Gauge), provide a 110 DB alarm to warn that the tank is reaching capacity.  The following documents provide testing results and ordering info:

  • 90% Overfill Gauge Ordering
  • Intrinsically Safe Documentation on the gauge alarm
  • Recommended Maintenance and Installation Procedure on liquid level tank gauges

In cases where liquids are flammable and fire protection is paramount, adding the Glass Calibration and the Aluminum Lock Nut to the gauge should eliminate the plastic from the gauge and provide a glass and metal barrier between the inside of the tank and the outside.  For additional protection, upgrade the Aluminum Nut to the Gauge Guard.

Already have a Krueger Gauge and want to get it up to code.  If the gauge is fully functional, just order our upgraded Fire Protection Gauge Repair Kit  and an overfill alarm.  In the case of the kit, we will need to know what gauge type you have.  Example part number is (-”gauge type”-Kit-GLC-ALN). Both the kit and the alarm are easily retrofitted to existing Krueger Tank Gauges.

DEF Storage Tank Regulation

DEF STORAGE TANK REGULATION

Source: PEI Journal | Written by Rick Long

REGULATION OF TANKS CONTAINING DEF

BACKGROUND

Nitrogen oxide (NOx) is a major air pollutant that contributes to smog, asthma and respiratory and heart diseases. It’s a by product of diesel fuel’s high combustion temperatures, which results from the high frictional heat levels created by compressing air in the cylinders to the point at which it can ignite diesel fuel without a spark. This is unlike a gasoline engine, which uses spark ignition to burn gasoline.

Beginning in January 2010, no new on-road vehicles can be sold without meeting EPA’s tougher Tier 2 Emission Standards
for Light Duty and Heavy Duty Vehicles. The new standard is 0.2 grams of nitrogen oxide (NOx) per brake horsepower. This regulation will reduce allowable nitrogen oxide levels by 90 percent from today and by 96 percent from 1994.

While gasoline engines have no problem meeting the new standard, vehicles with diesel engines have to utilize new technology to achieve the more stringent emission regulations.

The technology most vehicle and engine manufacturers will rely on is Selective Catalytic Reduction (SCR), which uses a urea-based diesel exhaust fluid (DEF) and a catalytic converter to change smog-forming nitrogen oxides into harmless nitrogen and water vapor. SCR treats exhaust gas downstream of the engine. Small quantities of DEF are injected into the exhaust upstream of a catalyst, where it vaporizes and decomposes to form ammonia and carbon dioxide. The ammonia (NH3) and SCR catalyst then convert the NOx into nitrogen and water.

COMPOSITION OF DEF

Current DEF formulations are a nontoxic, colorless and nearly odorless mixture of 32.5 percent chemical urea and 67.5 percent deionized water. Urea is the nitrogen-containing compound that transforms into ammonia when heated. Similar urea/water compounds are used in various industries, including extensive application as an agricultural fertilizer.

DEF is not a fuel; it also is neither flammable nor combustible. The product is also extremely heavy—at just over nine pounds per gallon.

STORAGE OF DEF

The industry expects diesel exhaust fluid (DEF) to be stored in small-size containers, drums, totes and intermediate bulk
containers (IBCs), as well as in bulk from both aboveground and belowground tanks.

While the initial supply of DEF will most likely be in packaged containers, larger-scale bulk storage and dispensing is just around the corner. One example suggests why: New truck models will have onboard DEF tanks capable of storing up to 20 (or more) gallons of DEF. A driver with even a mid-sized 13-gallon DEF tank would have to cart and pour almost 120 pounds of packaged DEF for a complete fill-up (13 gallons x 9.2 pounds per gallon = 119.6 pounds).

Given such realities, our industry must understand as quickly and authoritatively as possible how the federal government and
the states plan to regulate larger-scale bulk storage and dispensing of DEF. Good information will be crucial if businesses are to make sound decisions and commitments in the design of their DEF refueling operations.

ABOVEGROUND DRUMS, TOTES, IBCS, AND TANKS

Most people associated with the petroleum marketing and equipment industries know that aboveground tanks (ASTs) storing “oil” are regulated by EPA under the Spill Prevention, Control and Countermeasure (SPCC) rule. Since DEF is composed of aqueous urea which does not meet the SPCC definition of “oil,” ASTs containing DEF (including drums, totes, IBCs and tanks) are not regulated by EPA.

However, a word of caution is necessary here: Some states develop and enforce regulations that are more stringent than the federal rules. Check your state’s aboveground storage tank regulations before installing any AST containing DEF.

OVERVIEW OF FEDERAL UST PROGRAM

The federal underground storage tank (UST) regulations apply only to underground tanks and piping storing either petroleum or certain hazardous substances.

Today, the federal EPA estimates that approximately 617,000 underground storage tanks at close to 233,000 facilities operate under the federal UST program. Nearly all these USTs contain petroleum. Most estimates are that less than 10,000 tanks hold hazardous substances covered by the UST regulations.

Just as DEF does not qualify as an “oil” under EPA’s AST program, aqueous urea is not a “petroleum” substance under EPA’s UST program and therefore is not regulated as a petroleum product.

By itself, aqueous urea also falls outside of EPA’s definition of a “hazardous substance.”

Some confusion in the regulatory community develops, however, because DEF may contain up to 0.2% ammonia, and ammonia is one of about 1,200 substances identied as a hazardous substance under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). That becomes important because UST systems that store substances identied as hazardous under CERCLA are subject to the same requirements as petroleum UST systems, except that hazardous substance tanks must have secondary containment and interstitial monitoring. That means hazardous substance USTs must meet the same requirements as petroleum USTs concerning correct installation, spill, overll and corrosion protection, corrective action, and closure.

DE MINIMIS CONCENTRATION?

But another wrinkle may come into play in determining whether CERCLA will apply to UST systems containing DEF.

The federal rules exempt from federal UST regulations “any tank system that contains a de minimis concentration of regulated substances.” Rather than dening de minimis, the rules permit EPA to determine de minimis levels on a case-by-case basis. In the past, EPA has used the de minimis exception to exempt materials with very small, trace amounts of hazardous substances.

Since the amount of ammonia present in DEF USTs is very small, it is very possible that EPA will determine the level of ammonia would be regarded as de minimis and therefore exempt from federal UST regulations.

The industry has two other things going for it which may lead EPA to exempt DEF. First, the DEF manufacturers and others are very concerned not only with incompatible equipment materials causing the DEF to degrade and/or be contaminated, but also with DEF causing corrosion or somehow reducing the integrity of the equipment that can cause risk to the environment.
That, coupled with the willingness of various groups within the DEF community to insist on secondarily contained underground tank systems with interstitial monitors, might help the decision makers at EPA determine that the environmental risk from DEF USTs will be minimized, even absent EPA regulations.

WHAT HAPPENS NEXT?

The ball is now in EPA’s court. EPA is in the process of developing an official interpretation on whether DEF USTs will qualify for the de minimis exemption. We anticipate an answer soon—most likely this summer—but we don’t have one yet. Once EPA issues its interpretation, PEI will let you know.

Please note: As with ASTs, state UST regulations may be more stringent than EPA’s. Check your state’s UST regulations before installing an UST containing DEF. State UST program contact information is available at EPA’s website www.epa.gov/oust/states/statcon1.htm.

    Remote Liquid Level Gauge Monitor- Extreme Tests

    LED At A Glance Remote Monitor – Liquid Level

    The LED At A Glance, a remote display accessory for the Krueger line of liquid level gauges, has been put through some rigorous weather tests and has passed with flying colors.

    Early in the winter season, we set up some liquid level gauges outside the shop mounted to some 55 gallon drums.  The wires for the remote level monitors were then run over to the wall and the LED At A Glance remote level gauge displays were then set up in exposed areas.

    LED At A Glance Remote Monitor – Liquid Level

    Luckily, (for our testing purposes anyway), we got hit with a major snow storm. (18 inches of snow, 20 below zero with windchill).

    Pictured above (the first picture) you can see the exposed remote display wire encased in ice.

    Pictured directly above, you can see how the remote liquid level monitor itself was totally buried in snow and then dug out.

    Although we do suggest placing a hood or some other sort protection over the level monitor, in all testing cases the remote liquid level monitor still worked great after the storm went through.
