County 1, Texas 2018 – 2019 Petroleum Fuel Sites Evaluation Project

Fuel Analysis, Coupon Project and Field Notes September 2019

County 1 Project Overview

Fueling priorities are different for different sectors of the petroleum fueling industry. For example,

for a retail chain, having fuel consistently available along with quick access, clean bathrooms and

quick checkout for commuters may be the most important day to day priorities.

Federal, state, and other governmental organizations and agencies, and power sensitive businesses

and organizations have highly sensitive fueling priorities. While some are concerned about day to

day fleet fueling operations where high quality fuel keeps vehicles available, operational and

reduces maintenance costs, some are more concerned about even more stringent standards for

primary and backup power generator fuel. At these facilities, failure means loss of operations at

hospitals, data centers, security loss at jails / prisons and public buildings, fuel availability for

natural disasters including hurricanes, floods, ice storms, snowstorms, earthquakes, and other

needs not listed here.

The County 1 Texas project is designed and intended to:

• Identify fuel site locations that have fuel quality issues causing fleet and equipment damage.

• Detect and identify precursors of aggressive corrosion in fueling systems.

• Detect sites that have internal corrosion. Corrosion that, while not visually detectable externally, is causing fuel system degradation.

• Once identified, tools to measure the mm per year of pitting / corrosion deterioration. This is useful to predict potential future infrastructure failure and prioritize asset

management and protection.

• Provide information on proactive and reactive measures to stop or prevent infrastructure damage.

In developing this program, Vaporless Manufacturing Inc. (VMI) brought together years of

multidisciplinary field experience. Ranging from lead personnel in construction, maintenance,

system development for fuel transitions from gasoline and diesel to biofuels, and from one fuel

type such as gasoline to a compressible fuel (diesel or similar fuel group) – to fuel cleaning and

fuel testing specialists, biocide manufacturers, equipment manufacturers, equipment installers,

chemists, research and development engineers, equipment certification organizations – to

regulators and personnel working with and advising both water and air quality personnel.

3

VMI has included ideas and concepts that have been vetted through field research, laboratory

research and other interested parties including tank and equipment manufacturers to bring new

standard practices to find hidden dangers. By partnering with a leading lab, we are able to provide

field tests that reduce costs and provide a means to identify hidden dangers including the presence

of low pH fuels and water.

In particular, sites without visible damage, but with hidden damage are the most troublesome.

These sites are most concerning as they represent the ones that start causing problems without

being obvious. Treating the symptom of this type of problem is common. The constantly clogging

filters, the reduced flow in-between filter replacement, the chemical, labor, equipment

replacement, downtime for cleaning and labor costs for cleaning, the reduced lifespan for tanks

and other equipment including dispenser valves and meter drift. The list goes on. These sites may

have little or virtually no visible signs of aggressive corrosion until fuel is running out of the sump,

or if not tight, into the soil or water supply. It includes sites where there is undetectable damage to

flex connectors, until they rupture, where the dispenser shear valves and overfill prevention valves

are rendered inoperable, and where the fuel gauging equipment sensitivity and operability is being

affected until it is under-reporting the fuel in a tank, then unable to identify the overfill danger.

This is a standalone program, in addition to the EPA and state inspection guidelines, not a

replacement program for any required governmental regulation. The program recommendations

herein will complement and enhance the intent of state and federal inspection guidelines to reduce

the possibility of fuel leaks.

Program Description

As part of the County 1 project, baseline fuel analysis of all fuels was conducted by two methods

that included field tests and lab analysis. These fuel samples will be pulled on all identified tanks

by County 1 and their fuel contractor. Once test samples were secured, A36 Steel and C122 Copper

coupons were positioned in the vapor space or ullage of the tanks and in the correlating sumps.

The placement of these coupons allowed County 1, County 1 Consultants, “A” Petroleum

Contractor and Vaporless Manufacturing to examine the activity inside the tanks and sumps for

degradation, corrosion and metal contamination effecting both types of coupon (Copper and Steel)

over a period of ninety days.

Coupons and Material utilized in the sampling consisted of the following:

• VT-CC1010 - C122 Copper Coupon

o 2-7/8” x 7/8” x 1/8” C122 Copper Coupon, Glass Bead Finish, Weighed, Printed

VCI Envelope, Serial Numbers

• VT-CS1010 - A36 Steel Coupon

o 2-7/8” x 7/8” x 1/8” A36 Steel Coupon, Glass Bead Finish, Weighed, Printed VCI

Envelop, Serial Numbers

• Jellas Universal Test Paper – pH-14 Test Strips (field test)

• AWS-600 Digital Scale – Field weight measurement

• General IRT Infrared Thermometer

• Extech Instruments RH100 Hygro-Thermometer & InfraRed Thermometer

• Bundle Cable Ties 14” - #CB14 to secure coupons placement

• All Coupons to be placed in “Vapor Space” or “Ullage” of the tanks unless otherwise noted.

Field review and periodic weighing was scheduled for every thirty days from the date of install for

a ninety-day period. Coupon weights and photos of the process were captured in the field and

recorded in field notes to track the progress of the project. Once the ninety-day period was

5

completed, on the ninetieth day, final weights and photos were taken. At the time of the termination

of the ninety-day study, the coupons were collected and placed in their original protective

packaging from the lab, sealed, labeled and returned to lab by VMI for cleaning, weight change,

pit evaluation/analysis and coupon photo analysis.

Lab analysis will be sent to Vaporless Manufacturing for initial review. Once initial review is

completed, Vaporless will schedule meeting to deliver results and review findings with “A”

Petroleum Equipment Contractors and County 1 Consultants. County 1 Consultants will deliver

and review results with County 1.

VMI Field Tests Consist of:

• VT-001 – Water Exceeding 500 ppm (Parts per Million)

• VT-002 – Microbial Growth 72 hr. culture

• VT-013 – Acid Test indicating lower than .5, between .5 to 1.0, or greater than 1.0

January 23, 2019

County 1 project was started. We mobilized to the County Toll Road Site located at 12345 County

Road, County 1, Texas. Participants in the initial project were, Vaporless Manufacturing,

Consultant to Vaporless Manufacturing, “A” Petroleum Equipment Contractor, County 1

Consultant and Engineering Firm and County 1 officials.

County Toll Road Site Review Conditions

Once on-site, analysis was completed. The analysis of location, sumps, tanks, vent stacks was

completed.

The beginning of the process was the initial review of the diesel and gas sumps. Upon removal of

the cover of the diesel sump, we found that the sump was fully submerged in water. Upon removal

of the cover of the gas sump, we found that the sump was fully submerged in water.

We started removing the water from the diesel system sump to gain access to the UST. We

removed the ATG and noted the contamination on the existing cap of the ATG riser.

County Toll Road Vent Caps

The ATG components were replaced in July 2018 but not the cap. The cap was showing signs of

copper sulfate and corrosion. It appeared that the corrosion was leeching back into the top of the

ATG riser.

7

We completed (3) field pH samples on

the exposed metals in the sump and

recorded those samples (6.2 +/-). We

continued to examine the condition of

the submersible and all components.

We were unable to place coupons in

submersible due to excessive water.

We completed the exact same process

for the gas tank (AST). We pulled the

ATG and examined all the

components within the gas system. It

is noted that that Stage 1 was holding

vacuum. We proceeded to place

coupons in the gas tank, using the

ATG support fixture. We were unable

to place coupons in submersible sump

due to excessive water (results below).

County Toll Road Field Test Results 1-23-19

“A” Petroleum Equipment Contractor filled fuel sample tests containers at the County Toll Road

Site. The first samples were pulled from the middle of the diesel tank and field sample tests were

conducted. Samples appear to be clean and tested negative for water exceeding 500 ppm (parts per

million). Acid field test were conducted which appeared to be below .5. We will wait for the results

of the field microbial test (72 hr test, managed by County 1 personnel).

Upon completion of the middle of the tank diesel fuel samples, we took bottom samples from the

same tank. The bottom samples tested immediately for water exceeding 500 parts per million, acid

over .5 and again we will wait for the microbial test to be returned (managed by County 1

personnel).

We proceeded to test the gas tank with the field tests as well. We tested the middle of the tank for

acids and microbials. These field tests appeared to be clean and passed not to exceed .5 of acids.

As we tested at the bottom of the tank, the acid appeared to be positive exceeding .5 and we will

await the test for microbials to be completed (managed by County 1 personnel).

We proceeded to move forward to the next location initiating the same procedure. Upon arrival we

removed the covers of the submersible and fuel delivery sumps. Inspected both gas and diesel

sumps.

Both sumps showed signs of a mild to severe degradation. We proceeded to pull the ATG probes

and noted the degradation inside the ATG riser in the diesel tank. We completed (2) pH field tests

on exposed metals which resulted in a 6.2 +/- pH.

Once completed, we pulled fuel samples out of the middle of the tank, which appeared to be clean.

We perform a field test on the middle samples, and they appeared to pass water not exceeding 500

ppm, acids appearing to be negative and again awaiting the results managed/controlled by County

1 personnel.

Bottom samples were taken out of the diesel tank and immediately tested positive for water

exceeding 500 ppm. Field acid test was positive for acids in the fuel and waiting for the microbial

test to be completed (controlled by County 1 personnel). We completed the placement of coupons

in the ATG riser as well as placing coupons in the sumps.

We moved to the gas tank and completed the same process by pulling fuel samples out of the

middle of the tank. Acid and microbial field tests were completed. Field water tests (PPM) for

12

gasoline are not available. Field acid test showed no signs of activity, and again completed the

microbial testing awaiting results (controlled by County 1 personnel).

Once again, we pulled field samples off the bottom of the unleaded gas tank and noted acid testing

positive for high acid content and again awaiting microbial test to be completed (controlled by HC

personnel). We proceeded to place C122 copper coupons and A36 steel coupon in the ATG riser

as well as in the sumps. All coupons will be reweighed at the 30, 60 and 90-day intervals.

The unleaded gas tank and gas sump showed very little signs of degradation or copper sulfate.

Most of the appearance of the coupons were decent. Coupon weights and pictures were taken.

Diesel tank and diesel sump coupon weights and pictures were taken. The copper coupon

appearance was slightly covered in micro activity or contaminants. The steel coupon, on the other

hand, was showing signs of aggressive corrosion and contamination.

A field pH level was taken, and it measured at 5.5. There seems to be a correlation between the

aggressive corrosion on the steel in the tank and the pH level on the material in the sump.

County 1 Jail, County 1 Texas (E-Gen Site/Red Diesel).

Pulled diesel fuel samples out of underground tank. Field test were performed on-site from the

samples pulled. Sample will be sent in for lab analysis and will perform VT-004 w/Stability.

** Should be noted that the diesel fuel sample was pulled from the bottom of the tank. **

This sample visually indicated that there was a substantial amount of water in the bottom of the

tank. More than 70% of the fuel collected in the 16 oz container was water. This amount of water

is highly unusual and could/will result in generator failure. It was highly recommended that the

contaminated tank be cleaned, water removed, fuel polished and treated to prevent future failure

during an emergency.

Field fuel test conducted included;

• VT-001 Water appeared to exceed 500 ppm.

• VT-013 Acid appeared to exceed .5.

• VT-002 Microbial tests were completed and given to Sean to control and will wait 72 hours

for result.

Lab Comments:

• Water and Sediment exceeded acceptable limits. Sediment can cause clogged filters and

may lead to failed fuel injectors.

• Acid Number - The unknown substance caused by a phase separation is suspected to

contribute to the high acidity of the sample.

• Water suspended by Karl Fischer - Phase separations interfere with the accuracy of

determining entrained water.

County Service Center Precinct #4 After Analysis C007 & C005

Conclusions and Recommendations

VMI was invited to conduct fuel quality testing and analysis for County 1 , Texas . We tested and

studied several County 1 fueling systems, ullage or headspace and sumps in Aboveground Storage

Tank (AST) and Underground Storage Tank (UST) structures. Test sites included County 1 Toll

Road, County 1 Park, County 1 Jail, County 1 Data Services Center and County 1 Service Center

Precinct #4A. VMI took a three-pronged approach to study – Field Test, Lab Test and Coupon

Analysis. In the beginning of the process, we completed field fuel test that included:

Field Testing

• VT-001 - Water Exceeding 500 ppm

• VT-002 - Microbial Growth 72 hr. culture

• VT-013 – Acid Test indicating a pH lower than .5, between .5 to 1.0, or greater than 1.0

Lab Testing

We pulled fuel samples for VT-003 expanded fuel analysis that included:

• Acid Number ASTM D974-08

• API Gravity by Hydrometer ASTM 1298-99

• Cetane Index ASTM D976-01

• Distillation – 90% ASTM D86-08a

• Flash Point ASTM D93-10

• Microbial Growth Micro/Culture Medium

• Particulate Contamination ASTM D6217-08

• Water by Karl Fischer ASTM D6304-07

• Water & Sediment ASTM D2709

• Appearance ASTM D4176

Coupon Analysis

A36 Steel and C122 Copper coupons were installed in the ullage and sumps of the tanks, where

possible, to learn how fast degradation starts to occur. 30, 60 and 90-day intervals were set to pull

the coupons and complete field observation, monitoring and measurement of the coupons. On the

90th day, we pulled for a final weigh-in and packaged for transport to the lab for analysis.

By conducting this study, we were able to determine corrosion type and rate as well as levels of

water, acid, microbial growth, particulate contamination, and sediment as well as other items based

on petroleum industry standards and ASTM specifications.

55

It is impossible to determine fuel quality and increased potential system failure by sight. Evidence

of poor-quality fuel requires controlled testing and analyzing of the results to determine where the

fuel and the system have broken down. Based on the fuel tests and coupon tests performed, we

found microbial growth, lowered pH (acidic) coupon degradation representative of the loss of tank

shell thickness between 0.068 ml per year to 2.035 ml per year. The evidence of cupric oxide

appeared to be on the copper coupons we pulled from several of the tanks.

Acidified water and fuel are the foundational cause of component failure. Component failure

includes both infrastructure, vehicle components and systems, and emergency systems. The

presence of water, oxygen and food sources allows microbes to thrive. The excretion, or waste, of

the acetobacter is acetic acid. This acidified fluid is a cause of increased system degradation,

particulate contamination and acidic water and fuel. Systems and component failures include but

are not limited to, tank failure, erosion of electrical conduit, submersible motor failure, motor

column detachment, impact or shear valve failure, flex connector and leak detector degradation to

the point of failure without warning. The effect of increased particulate contamination (coffee

ground type sediment / particulate) can lead to increased filter changing, nozzle stickage, leaking

and failure, blender valve failure, sheer valve failure, meter drift, injector wear (poor performance

and lower mpg) and injector failure. Obviously, tank degradation and fluid component failure such

as flex connectors and line leak detection failure can lead to catastrophic releases of fuel into the

environment as well as the release of saturated acidified hydrocarbons while tanks are under

pressure. All these possible points of failure will lead to increased maintenance costs.

First, the good news, there are sites that show little or no corrosion. These sites should continue a

quarterly fuel monitoring program, continued fuels tests from the nozzle of dispensers looking for

changes in pH, water content and biologicals. Additionally, we believe any tank that is “breathing”

high humidity air should also have a bottom fuel sample taken quarterly to see if a water bottom

is present. Current recommendation for water in tanks is NONE. If no water is detected from fuel

testing and water bottom check, no fuel samples of vehicle gasoline or diesel need to go to a lab.

Any tanks with water indicators should have lab fuel analysis and the tank system evaluated for

tightness to determine how water is accumulating in the tank.

Corrective actions for tanks that have issues today or in the future should follow basic industry

recommended practices:

• ensure the tank top is liquid / vapor tight

• removing the water bottom

• treat the fuel with biocide

• clean the fuel

• clean the tank

This is always the first course of action, no matter what the second course of action is.

With the information gathered, we can state that there are sites with significant issues. Two sites,

County Toll Road diesel tank and County Park diesel tank, are experiencing accelerated corrosion.

56

This accelerated deterioration will cause a premature containment breach. There are low pH and

high particulate issues that are adversely affecting fleet performance.

There is emergency generator equipment (County 1 Jail) in danger of not being able to perform

under full load for extended periods of time. Genset fuel tanks have a higher threshold (200ppm)

of cleanliness and specific fuel properties to maintain. The fuel should be tested by lab analysis on

a quarterly basis. Day-tank fuels should be polished on at least a weekly basis. Day-tanks and

diesel fuel tanks for gensets should have quarterly bottom sampling to detect for water bottom.

Out of specification genset fuel, particularly the reoccurring presence of water / acidified fuel are

indications that additional methods of protecting the systems and the fuel are required. See

Nitrogen recommendations below.

By recognizing the causes and effects in the current infrastructure, facility operators have the

ability to be proactive with a solution that is a comprehensive approach compared to the fail and

fix concept of system management. Introducing a consistent and ongoing fuel testing program,

both field and lab analysis approach, along with Nitrogen Blanketing as a replacement for the

moist air being pulled into tank systems now, where appropriate to the fuel system, will help reduce

costs by stopping the penetration of atmosphere. This will stop the intrusion of water. By

blanketing the fuel system, microbial growth will be inhibited, and the cycle of destruction will be

stopped. By reducing O2 & H2O atmosphere in the tank and controlling the tank environment, the

utilization of Nitrogen extends the life of equipment and maintains fuel quality. When Nitrogen is

released upon positive pressure, we know we are not destroying the environment with

hydrocarbons or benzenes.

Nitrogen gas blanketing of the headspace of tanks has proven to have many benefits. One such

benefit is how the NBS changes the tank’s environment to prevent the conditions that provide

water for germination and oxygen for respiration for colonies to grow. Eliminating water and

oxygen prevents serious damage that has led to failure of fuel storage containment boundaries.

API 2000 6th and 7th Editions address environmental corrosion control for large fuel tanks. These

protocols are in use at refineries, bulk fuel storage facilities, bulk fuel transfer terminals and

airports worldwide. The consensus of a group of state regulators, fueling system component

manufacturers, and operators of retail and commercial fueling sites is that the conditions causing

corrosion damage to fueling system components in retail market fuel storage equipment can best

be addressed by adapting API environmental corrosion control (API 2000 6th and 7th editions)

protocols. These adapted protocols should be one part of a comprehensive program that seeks to

identify corrosive environments and prevent or stop damage to retail and commercial fueling

equipment.

It is highly recommended that, where appropriate, County 1 utilizes VMI’s Nitrogen Blanketing

Equipment in their fuel farm systems including emergency generators to maintain a quality fuel

program. The NBS system is designed to prevent the formation of corrosive, damaging

atmospheres in commercial fuel storage tanks. The system is an intrinsically safe Environmental

57

Corrosion Control method that inhibits or prevents the growth of bacteria, molds and yeasts that

may occur in the ullage of tanks and produce acidic deposits that cause serious

damage and failures to tank equipment.
