Protocol Development Preventative and Reactive Defined
Gasoline Ethanol/Water Phase Separation

Preventative Protocols
define processes and procedures to be followed primality to prevent fueling system down time, customer inconveniences and or value loss of products being stored and marketed. As well to define preventative processes and procedures to insure fueling system component design optimum operation and reasonable expected safe operation.

Reactive Protocols
define processes and procedures to be followed when situations or events expected or unexpected arise causing un-warrantied system component failures, customer inconveniences, loss of stored product value, volume contract commitments, damage or potential damage to the surrounding environment.

Philosophy often accepted is that defined preventative methods and procedures generally are more economical than reactive, unmeasured, irregular or inconsistent methods addressing issues or problems inevitable or unexpected. Economic and or operational and number of site scopes typically dictate and define interim and or term preventative and reactive service and maintenance protocol.
Incident or situations where a problem or component failure becomes catastrophic in effect might and overall should be considered rare. Preventative protocol program cost economics can typically be determined by incident numbers in regions over time. The number of operational sites with probable event statistical formulation will determine the associated risk and economics of a prevention over reaction response program. Simply a larger number of operational sites typically and statistically will allow accurate forecast of minor and catastrophic events. Event forecasts and associated costs if reasonably accurate often suggest only established and well defined reactive protocols and measures. Regardless of choice, preventative or reactive, it is important that within company operating policy both be well detailed and defined.

As we see more unexpected product formulation changes, fueling system containment boundary integrity and component corrosion failures it should be considered wise to aggressively prepare and develop adequate incident prevention and reaction protocols.

Preventative protocols when established and implemented require uniformed procedural understanding. It is assumed that primarily selected and preferred servicing contractors reasonably understand the basic operational and fundamental design dynamics of a fueling system dispensing and storing motor fuels.

Basic preventive measures are typically established and defined by industry consensus, the sites operation management and a selected servicing contractors experience preventing and resolving other than minor fuel delivery and fuel storage quality issues expected or unforeseen. Adequate preventive measures typically identify potentially negative fuel storage tank and fuel delivery practices and operating scenarios effecting quality and or marketability of motor fuel.

It is important to establish a basic and regular preventive inspection routine to identify possible fuel quality damage and contamination conduit paths. Regularly scheduled site, tank top fitting tightness and vent riser position inspections should be basically and fundamentally a priority. All site equipment servicing contractors, store personnel and site operation management for whatever reason on site must be conscience and noteworthy of equipment operation conditions or customer complaints that might signal slow or irregular fuel flow and a potential fuel quality issue.

Reactive protocols when established and implemented are based on the assumption that a fuel quality issue probably exists.

On site store personnel are often first to become aware of problem issues either by customer complaint, a regulatory inspection or by required acknowledgment of an electronic tank monitoring alarm. Though customers tend to complain it is wise to take seriously any customer questioning dispenser slow fuel flow, vehicle over flow (fuel spill) when fueling or customer fueled vehicle drivability issues. These scenarios can and should justify an immediate stop sale of product being dispensed at all fueling points. An electronic fuel monitoring alarm requiring acknowledgement especially during or just after heavy rain and or just after a bulk fuel delivery should as well be taken seriously. Electronic monitoring equipment alarm signaling “WATER, HIGH WATER or TANK OVER FILL” justifies an immediate stop sale of product being dispensed at all fueling points.

For onsite responding to possible issue service personnel it is important to understand initially what set of conditions exist causing electronic monitoring device in alarm, slow fuel flow, customer complaint or actual fuel quality issues.

The common fuel quality problem causing scenarios are:
Normally occurring and or unmonitored naturally resident water volumes in the fuel storage tank that has reached a level high enough to be sensed by electronic monitoring equipment. Resident water can exist as water or a water/ethanol heavy phase in any gasoline or diesel fuel storage tank. The difference in relative weight causes this contamination constituent to accumulate at the lowest point in the tank. Depending on the slope of the tank the accumulation of contamination over time may remain undetected until contamination volume reaches monitoring and sensing in tank probe.

Contamination conduits are typically loose tank top fittings, missing fill tube adapter and or cap gaskets, missing or broken fill and vent caps, damaged vent riser swing joints, damaged or dirty fill and vent containment over fill container drains. More problematic contamination conduit paths are fill, vent, ATG and motor risers loose, corroded or disconnected below grade. As well turbine sumps often contain sufficient volumes of water covering tank ullage connecting ports and turbine head packer o-rings. With the installation of tank pressure vacuum valves to control hydrocarbon fugitive emissions tank empty space atmosphere negative pressures through loose system component grade and sub grade fittings encourage water ingress.
