                    Periodic Walk-Through Inspections
To quickly detect and prevent releases, you should conduct basic walk-through inspections of
your facility frequently to make sure that your essential equipment is working properly and that
you have emergency response supplies on hand. Make sure any problems you find are fixed.
Your initials in each box below the date of
the inspection indicate that the device/
system was inspected and was in working
order on that date.
Release Detection System: Inspect for
proper operation.
Spill Buckets: Make sure spill buckets are
clean and empty and have no cracks or
holes.
Overfill Alarm: Inspect for proper operation.
Can a delivery person hear or see the alarm
when it goes off?
Impressed Current System (if installed):
Inspect to make sure it is on and operating
within normal voltage and amperage values.
Fill And Monitoring Ports: Inspect all
fill/monitoring ports and other access points
to make sure that the covers and caps are
tightly sealed and locked.
Spill And Overfill Response Supplies:
Inventory and inspect the emergency spill
response supplies. If the supplies are low,
restock them. Inspect supplies for
deterioration and improper functioning.
Dispenser Hoses, Nozzles, And
Breakaways: Inspect for loose fittings,
deterioration, obvious signs of leakage, and
improper functioning.
Dispenser And Dispenser Sumps: Open
each dispenser and inspect all visible piping,
fittings, and couplings for any signs of
leakage. If any water or product is present in
the sump, remove it and dispose of it
properly. Remove any debris from the sump.
Piping And Piping Sumps: Inspect all
visible piping, fittings, and couplings for any
signs of leakage. If any water or product is
present in the sump, remove it and dispose of
it properly. Remove any debris from the
sump.

                                    Preamble

This document constitutes a model manual that the United States Environmental Protection
Agency (EPA) has prepared to assist states in adopting an Environmental Results Program
(ERP) where they choose to do so.  EPA has based this model manual on its federal
underground storage tank regulations that appear in 40 C.F.R. Part 280.  States that choose to
participate in ERP (either as a voluntary or mandatory program for their regulated community)
and wish to use this model manual may need to revise it, as appropriate, to reflect their state
underground storage tank regulations.

In this model manual, EPA describes federal regulations that already exist. This  model manual
does not create or impose any new requirements. The references to language such as "must"
or "shall" throughout chapter 4 of the document do not create or indicate any new requirements
or obligations for the regulated community, but merely reflect the existing requirements that are
currently contained in 40 C.F.R.  Part 280.

This model manual includes some suggested sample tools for  an ERP program that are not
existing requirements under federal law (for example, the model certification of compliance form
in appendix A and the model return to compliance plan form in appendix B).  States may choose
to require such tools under state law.

Since this is a model manual only, states may depart or vary from it. EPA intends for this
manual to serve as a model tool to assist states in developing their own ERP manual. In this
spirit, EPA fully expects that many states may make numerous revisions to this manual in
developing their state ERP manual. Each state will have to implement its own state law to
impose any requirements associated with its own ERP.  Depending on each state's law, states
may need to modify language  in this manual. The regulated community then may be required to
follow the final ERP manual that its state has modified and adopted. The regulated community
is not required to follow this EPA model manual.

EPA has written this model manual in a format that serves as a sample for states to use in
developing their own manual.  The language, structure,  and  organization of the manual provide
one example of how a state manual might read.  Depending on actual requirements under state
law, states may need to revise the language and structure of this sample document.  For the
convenience of the states in referring to this model manual, EPA has written this  document in a
format  that uses sample language directed to members of the regulated community.  EPA has
also written this document in such a manner that assumes a state's adoption of an ERP.
Therefore, this model manual will only be relevant to those states that have chosen to adopt,
implement or require an ERP in their state and are now interested in preparing their own state
ERP manual by using the EPA manual  as a model.
                                    **Disclaimer**

    The Environmental Protection Agency and {state} do not endorse any companies or
    names that are mentioned or shown in this workbook.  Any companies, names,
    facilities, services, or commercial products in this workbook are shown only as a written
    or visual example.

          Chapter 1:  Does This Workbook Apply To Your Facility?

     This workbook is designed to help owners and operators of underground storage tanks comply
     with {state} environmental underground storage tank regulations.  These tanks, along with any
     connected underground piping, are called USTs in this workbook. The workbook uses the term
     tank when the underground tank is the only thing being discussed. This workbook describes
     requirements and best management practices (BMPs) for your USTs and helps you determine
     whether they are in compliance with the law.

     •   If you have underground storage tanks at your facility that meet the criteria described
         below, this workbook applies to you.
     •   If, after reading this section, you determine that the workbook does not apply to you,
         fill out the non-applicability form, if required, and send it to {state}. This will inform
         {state} that you do not have any USTs that fall under this  program. A model non-
         applicability form is in appendix C.

     To determine if this workbook applies to you, read and answer the following questions:
Question 1. Do you have any USTs at your facility?
Yes
No
 An underground storage tank or LIST is an:
   underground tank and underground piping.
   underground tank and aboveground piping (if at least 10% of the total volume of the tank and piping are
   underground).
   aboveground tank and underground piping (if at least 10% of the total volume of the tank and piping are
   underground).  This scenario is not common.

An underground storage tank is not an aboveground tank and aboveground piping.

• • If you answered yes, continue to question 2.
• • If you answered no, this workbook does not apply to you. If required, fill out a non-applicability form
   and send it to {state}.
Question 2. How many USTs at your facility meet at least one of the following criteria?
These are types of USTs that are covered by this workbook.
   contain petroleum or used oil (that will be recycled) at public gasoline stations or repair shops.
   contain heating oil that is not used (or consumed) on the premises where it is stored.
   are farm or residential motor fuel tanks greater than 1,100 gallons used for noncommercial purposes.
   are petroleum tanks owned by a federal, state, or local entity.
   are private petroleum tanks used for fueling of business vehicles (for example: bus terminals).
   contain a hazardous substance listed under the Comprehensive Environmental Response,
   Compensation, and Liability Act (CERCLA). An example of a hazardous substance is antifreeze.
   Contact {state} if you are not sure if you have a hazardous substance tank.
   store product for use by emergency power generators.
           Number
           of USTs
• • If you have at least one UST that meets the criteria above, continue to question 3.
• • If you have no USTs that meet the criteria above, you do not have any USTs covered by the
   Environmental Results Program. This workbook does not apply to you. If required, fill out a non-
   applicability form and send it to {state}.
                                                                                  Chapter 1

-------
Question 3. Of the number of USTs you identified in question 2, how many meet at least
one of the following criteria?
USTs that meet at least one of the criteria below are not covered by this workbook.
If you received this workbook, it would be unusual for all of your tanks to meet at least one of
the criteria below.
USTs are not included in this workbook if they meet one of the following:
   total tank and piping volume is 110 gallons or less.
   LIST with a tank that was constructed or built in the field (field-constructed).
   tank situated in an underground area, but situated on or above the surface of the floor.
   heating oil  tank that is used (or consumed) on the premises where it is stored.
   hazardous waste tank (in general, a hazardous waste is a hazardous chemical that cannot be reused
   in some way).
   tank containing radioactive materials.
   flow-through process tank (a tank that forms an integral part of a production process where there is a
   steady, variable, recurring, or intermittent flow).
   airport hydrant fuel distribution system.
   tank located at pipeline facility regulated under the Natural Gas Pipeline Safety Act of 1968 or the
   Hazardous Liquid Pipeline Safety Act of 1979 [or an intrastate pipeline facility regulated under
   comparable state laws].
   tank that is a part of machinery that contains product for operational purposes such as a hydraulic lift
   tank or electrical equipment tank.
   emergency spill or overflow containment tank that is quickly emptied after use.
   tank located at a nuclear power generation facility used for an emergency power generator.
Number
of USTs
  • If you have no USTs that meet the criteria in question 3, this workbook applies to you.  Begin using
   this workbook by reading chapter 2.
  • If you have at least one UST that meets the criteria in question 3, continue to question 4.
Question 4. What is the difference between the total number of USTs in question 2 and question 3?
Subtract the number of USTs in your answer to question 3 from the number of USTs in your answer to
question 2.
                                        Answer to question 2:
                                        Answer to question 3:
                                        The difference between the two:
   1 If the difference between question 2 and question 3 is "1 or greater," this workbook applies to you.
   Begin using the workbook by reading chapter 2.
   If the difference between question 2 and question 3 is "zero," you do not have any USTs covered
   by the Environmental Results Program. This workbook does not apply to you. If required, fill out a non-
   applicability form and send it to {state}.
      If you are not sure whether the workbook applies to you, call {state} at {XXX-XXX-XXXX}.
      If you are required by {state} to participate in the Environmental Results Program and you
      intentionally falsify your applicability, you may be subject to fines and penalties.
                                                                                    Chapter 1

                          Chapter 2:  Introduction

2.1  What Is The Purpose Of This Workbook?

This workbook is designed to:

   clearly explain {state} environmental, record keeping, and operation and maintenance
   requirements for USTs contained in existing {state} regulations;
   clearly explain voluntary actions that you can take to improve environmental performance
   and reduce financial risk regarding your LIST; and
   help owners  and operators of regulated USTs determine if they are in compliance with
   existing {state} LIST regulations through compliance checklists.

2.2  What Is The Environmental Results Program?

The Environmental Results Program (ERP) focuses on educating owners and operators of
USTs about the  existing {state} environmental regulations that apply to them and encourages
stewardship of the environment around UST tanks and piping systems. It allows users of the
workbook to understand and determine their compliance with existing {state} UST requirements.
Understanding the requirements and best management practices in this workbook and
complying with UST regulations will help you be more proactive in protecting the environment
around your USTs.  {State} environmental laws already require that you follow the requirements
described in this workbook. {State} will perform inspections with UST owners and operators
participating in the {state} ERP to ensure that compliance statements are accurate and that
environmental standards are being met.

As a participant  in {state} ERP, you will:

   use this workbook to understand the {state} requirements and best management practices
   for your USTs and determine compliance for USTs at your facility,

   be able  to attend workshops to learn about the {state} ERP  program;

   complete, sign, and send in the {state} certification of compliance form to {state}. On this
   form you will certify the current compliance status of your facility and acknowledge that the
   facility must  comply with all applicable environmental regulations. A model certification of
   compliance form is in appendix A;

   submit {state} return to compliance plan forms to {state} if there are compliance problems
   identified in the process of filling out the certification of compliance form that cannot be
   corrected at  that time.  The return to compliance plan describes what you will do so your
   facility meets requirements and when you will do it. A model return to compliance plan form
   is in appendix B; and

   be subject to {state} audits/inspections to confirm the accuracy of the certifications and
   compliance with {state} UST regulations.
                                                                            Chapter 2

-------
2.3 Why Participating In The UST ERP Is Important

There are several reasons why your participation in this program is important.

You are helping to protect public health and the environment.  Releases from USTs - spills,
overfills, leaking tanks and piping - can contaminate groundwater.  Your local community may
depend on that groundwater as a source of drinking water.  In addition, leaks from USTs can
result in fires or explosions, which threaten public safety.

You are protecting your economic investment. It is important to quickly detect, report, and
clean up releases, as required by the  UST regulations.  Preventing releases protects your real
estate investment. Any product that is lost in a release may cost you in terms of cleanup costs,
potential penalties, the lost revenue of product not sold, and resale value of your property.  By
responding quicky and containing a release,  you may be able to reduce cleanup costs and
environmental damage.

You are required to follow environmental laws  by complying with UST regulations.  If you are
the owner or operator of one or more USTs, you are legally responsible for preventing
and quickly detecting releases from your  USTs. You are also responsible for reporting and
cleaning up any releases that occur. You will be held accountable if your UST leaks.
Therefore, you should make sure releases do not occur.

This document is not a substitute for {state} law  and regulations, nor is it a law or regulation
itself.  For a comprehensive and complete understanding of the law and regulations, please
refer to [insert state statutory and regulatory  citations and state website here].

[Depending on whether state law requires member of the regulated community to  submit a
certification of compliance and return to compliance forms, the following suggested
language in section 2.4 is an example of what states can insert in this section, if applicable.]

2.4 Your ERP Requirements

Under state law [insert citation], you are required to submit a certification of compliance form to
{state} every year (appendix A).  Under state law [insert citation], you also must submit return to
compliance plan forms (appendix B) to {state} if  you are not in compliance when you submit the
certification of compliance form.

If you do not:
   meet the environmental requirements;
   send in  the certification of compliance form (and any return to compliance plan forms); or
   give accurate information on your certification of compliance form (and any return to
   compliance plan forms),

you could trigger an  inspection that may result in fines or other enforcement action by {state}.

If you have any questions as you go through this workbook, please refer to appendix F for other
resources or call {state} at {XXX-XXX-XXXX}.
                                                                            Chapter 2

                Chapter 3: How To Use This Workbook


This chapter will tell you:

    the organization of the workbook,
    how to complete chapter 4,
    how a person would fill out a section of chapter 4, and
    what the symbols in chapter 4 mean.

3.1.   Organization Of The Workbook

You have already read chapters 1 and 2. Chapter 1  showed you that you have at least one
regulated LIST and that this workbook applies to you. Chapter 2 explained what the
Environmental Results Program is and why it is important to comply with the existing {state}
regulations. This chapter will help you understand the rest of the workbook. There are two
remaining parts of the workbook, chapter 4 and the appendices.

Chapter 4 will help you understand what you have to do to comply with existing {state} LIST
regulations and to improve the environmental performance of your facility.  Chapter 4 contains
an introduction and 13 sections. The introduction includes a table to help you identify the USTs
at your facility. Each of the 13 sections covers a  different part of the existing {state} LIST
requirements. Read the beginning of each section and fill out a short checklist to determine the
parts of that section that apply to your facility. Then  read and complete the checklists that apply
to your facility.
 Do not be concerned about the size of chapter 4. You will only need to complete the
 parts of each section in chapter 4 that apply to your facility. Each section in chapter 4
 provides clear directions on which section parts you need to complete.
The appendices contain information and checklists to help you understand the workbook and
comply with existing {state} regulations. They include: Model Environmental Results Program
forms, other sample forms and checklists that can help you stay in compliance, and a list of
definitions for technical words used in the workbook.
 If you have any problems filling out the workbook, consult the outside back cover to
 find {state} contact information.
3.2. Steps For Completing Each Section In Chapter 4
 Directions: Important directions are provided in gray boxes like this one. There are
 specific directions to follow in each section of chapter 4.  Make sure you read the
 directions before starting a section.
                                                                           Chapter 3

-------
The steps for completing each section in chapter 4 are:

1.   Read the beginning of each section to understand if it applies to your facility. If you are
    sure it does not apply, you can skip that section. If it does apply, complete the section.
    The section may ask you to fill out a table to identify which compliance options are used for
    each of your USTs.  This table will help you understand which parts of the section you will
    need to fill out (if there is no table, complete that section). Use the LIST identification table
    at the beginning of chapter 4 to keep track of the USTs at your facility.

2.   Go to the parts of a section that apply to your facility and read the information on {state}
    requirements and best management practices. Next, complete the checklist as follows:
      Circle the "UST Number" at the top of the checklist for each UST that uses the option or
      meets the characteristics of this checklist.
   •  Answer the questions in the checklist for USTs that you circled at the top. Circle "Y" for
      yes or "N" for no in the column below each UST that you circled.  If you do not know
      the answer to a question, you will need to look up the relevant information in your
      records or call the contractor who worked on your site. Appendix E contains a list
      of definitions to help you understand the technical terms used in chapter 4. Answer
      either "Y"  or "N" for each question that applies to your facility.
      Leave all  questions blank for USTs that you did not circle.
 DIRECTIONS: Sometimes a question will tell you to complete a different section first to get
 the answer for the question. After you complete the other section, make sure you return to the
 original section you are working on.
3.   Answer the summary of compliance question at the bottom of the checklist page. This
    question summarizes your compliance with the option on that page. Read the instructions
    below the summary of compliance question to determine how to answer the question. If
    you answer "no" to the summary of compliance question, fill out a return to compliance plan
    form for each area of non-compliance and submit it with your certification of compliance
    form as required by {state regulatory cite}.

4.   Answer the final summary of compliance question for your facility on the last page of each
    section. The final  summary of compliance question asks whether all of your USTs are in
    compliance with the requirements discussed in that section.  If you answered "no" to any
    previous summary of compliance questions in the section, you must answer "no" to this
    question. As required by {state regulatory cite}, fill out a return to compliance plan form for
    each area of non-compliance and submit it with your certification of compliance form.

5.  After you have filled out the workbook, transfer your answers from the final summary of
   compliance questions in  chapter 4 to the certification of compliance form as required by
   {state regulatory cite}. Please note that the federal regulations hold owners and operators
   responsible for compliance.  Therefore, the owner or operator of the facility must sign the
   certification of compliance form {states  may need to modify this}.
                                                                             Chapter 3

-------
3.3 Example: Joe And The A&B Gas Station

The next few pages tell the story of Joe, the owner of a gas station, and how he filled out a few
parts of chapter 4 in this workbook. Joe is not a real person; this is a fictitious story to help you
understand how to fill out the information in chapter 4. Joe's story does not tell you everything
he did to fill out chapter 4, but will help you get started. If you already understand how to
complete the workbook, you may skip this section.

Joe's example is explained in dark, bold letters over the next few pages. Try to read the whole
story, because it will  help you understand how to:

1.   fill out the tables in chapter 4,
2.   complete the compliance checklists in chapter 4, and
3.   answer the summary of compliance questions in chapter 4.

Joe's Story

Joe is the owner of A&B Gas Station on the corner of Elm and  Main Streets. He also
owns Y&Z Gas on the corner of Maple and State Streets.  Joe is completing this
workbook for A&B Gas.  He will use the information he writes in the workbook to
correctly fill out his certification of compliance form for A&B Gas. He will need to fill out
a separate workbook and a certification of compliance form for Y&Z Gas.

Joe received the workbook in the mail from his state LIST program and began working on
it.  He knows starting early will help make sure he has time to collect the right
information and accurately complete the workbook.

Joe has three underground storage tanks at A&B Gas. One LIST holds gasoline, one
holds kerosene, and one holds used oil. The gasoline LIST is compartmentalized.  This
means the tank is divided into different sections or compartments. (Usually, each
compartment will have a different product in it.)  This tank has a compartment for regular
gasoline and a compartment for premium gasoline.

The three tanks are lined up in a row from east to west. Joe  usually calls the gasoline
tank the east tank. He calls the kerosene tank the middle tank and the used oil tank is the
west tank.  Joe's kerosene tank is  a lot older than his other two tanks, so he does not
know as much about that tank as he does about the gasoline tank and the used oil tank.

After reading chapters 1, 2 and 3, Joe feels he has a pretty good idea of how to fill out the
workbook.  He turns to chapter 4.
                                                                        Chapter 3

-------
Joe Identifies The USTs At His Facility

Before Joe can begin filling out any of the checklists in chapter 4, he has to complete the
table at the beginning of chapter 4; this helps him keep track of his tanks.  He will use the
numbers he gives to each tank in the table to identify them in the rest of chapter 4. He
follows the directions in the workbook to put the information for each tank into the table.
You can see a copy of Joe's completed table at the bottom of this page.

Even though the premium and regular gas are stored in the same tank, the directions tell
him to enter each compartment as a separate LIST. So Joe calls the premium section of
his gasoline tank LIST 1.  Joe knows the registration number of this tank, so he puts that
in the Identification Number column. He knows how many gallons the tank holds, so he
fills out the Size column. Joe also fills in the type of product contained in this
compartment and the size of the compartment. In the column called Other Identifying
Information, Joe writes that this tank is the east tank, since that is how he thinks of it.

Joe calls the regular compartment of the gasoline tank LIST 2 and fills in the registration
number and location. These are the same as for the premium compartment.  He also fills
in the size of this compartment and the type of product it holds.

Joe calls his kerosene tank LIST 3.  He does  not know this tank's registration number, so
he leaves that blank. He writes in the type of product and size and that this is the middle
tank.

Joe calls the used oil tank LIST 4 and fills in  the information for this tank. He calls this
tank the west tank.

Joe has a total of four USTs (since the premium and regular gasoline compartments
count separately). So he does not put anything in the fifth row of the table.

Now that Joe has identified all of his USTs, he is ready to look at the other sections in
chapter 4.  Joe reads the directions and fills out sections 4.1 and 4.2. He did not have
much trouble with these sections because he read the directions. We join Joe again
when he starts section 4.3. This section is a lot like the other sections in the workbook,
so seeing how Joe fills it out will help you.
                                                                       Chapter 3

-------
Joe Identifies The Types Of Overfill Protection He Has

First, Joe reads the instructions in section 4.3. He learns that overfill protection is
equipment on USTs to prevent tanks from overflowing when they are being filled. He
also learns that to be in compliance most USTs must have at least one type of overfill
protection.

Joe sees there  are three kinds of overfill protection the regulations allow: overfill alarms,
ball float valves, and automatic shutoff devices. An overfill alarm activates when a tank
is close to being full; this alarm can be seen and/or heard.  An automatic shutoff device
is located at the fill pipe of a tank; it stops product from flowing into a tank that is close
to full. A ball float valve is located inside a tank; it slows the rate of product flowing into
a tank that is almost full.

Joe already knows that he has an alarm for his gasoline tank. The information at the
beginning of section 4.3 helps him figure out that he has an automatic shutoff device on
his kerosene tank and no overfill protection for his  used oil tank.

At the beginning of section 4.3, Joe fills out a table that asks about the kind of overfill
protection on each of his USTs. This table tells him which checklists in 4.3 he needs to
fill out.  A copy of Joe's table is at the bottom of this page.

Using the UST numbers from the identification table he filled out at the beginning of
chapter 4 (see the previous page of this story), Joe marks that USTs 1 and 2 have overfill
alarms. (Remember that Joe was told to treat each compartment of his gasoline tank as a
separate UST.)  He also marks that UST 3 (his kerosene tank) has an automatic shutoff
device, and UST 4 (his used oil tank) has no overfill  protection. From this table, Joe sees
that he has to fill out checklists in sections 4.3.1, 4.3.2, and 4.3.4.  He will complete these
checklists next. None of Joe's USTs have ball float valves, so he can skip section 4.3.3.

Joe Completes The Overfill Alarm Section For His Gasoline Tank

Joe knows he needs to fill out section 4.3.1 because USTs 1 and 2 have overfill alarms
and the table at the beginning of 4.3 directed him to go to section 4.3.1. Joe turns to
section 4.3.1 and reads about the requirements and best management practices for
USTs with overfill alarms. Using that information, he answers the questions in this
checklist.
 A copy of Joe's checklist and summary of compliance question are on the right hand
 page, so you can follow along.  The next few paragraphs will tell you why he
 answered the questions the way he did.
At the top of the checklist, he circles the numbers 1 and 2, to show that these two tanks
have overfill alarms. He will not answer any questions on this checklist for USTs 3 and
4, since they do not have overfill alarms.

Since both UST 1 and UST 2 regularly receive more than 25 gallons of gasoline at a time,
Joe answers yes to the first question.

Joe recently had a technician check his overfill alarms, so he knows that they are
working according to the requirements he sees in the workbook.  He answers yes for
both tanks to questions 2 and 3.

The question at the bottom of the page is a summary question. Because Joe answered
yes to all of the questions on this checklist for his two USTs with  overfill alarms, he
answers yes to this question.
                                                                      Chapter 3

Joe Completes The Automatic Shutoff Device Section For His Kerosene
Tank

Joe knows he needs to complete section 4.3.2 because the table at the beginning of 4.3
told him to fill out this section for his kerosene tank, which has an automatic shutoff
device.  He reads the information about automatic shutoff devices before he answers
the questions.  The questions about automatic shutoff devices are like the questions
Joe answered about overfill alarms.
 A copy of Joe's checklist and summary of compliance question are on the right hand
 page, so you can follow along. The next few paragraphs will tell you why he
 answered the questions the way he did.
Joe starts by circling LIST 3 at the top of the checklist, since that is the only tank with an
automatic shutoff device. He does not circle the other tanks and will not answer any
questions for them.

Because his kerosene tank regularly receives more than 25 gallons of kerosene when it
is filled, he answers "yes" to the first question.

Joe's kerosene tank overflowed when it was filled last month. So Joe does not think his
automatic shutoff device is working and circles no for question two. He realizes he will
need to hire a qualified person to fix his automatic shutoff device so he can be in
compliance with the requirements for automatic shutoff devices.

At the bottom of the page, Joe reads the directions in the summary of compliance
question. He can only answer yes if he is in compliance with all overfill protection
requirements. Because he answered no to question 2, he answers no to the summary of
compliance question. He turns to appendix B and fills out a return to compliance plan.
The return to compliance plan tells the state how and when Joe will fix the problem.  Joe
will submit the return to compliance plan with his certification of compliance form.

Joe does not have any tanks with a ball float valve and the table at the beginning of
section 4.3 tells him he can skip section 4.3.3.  Next he turns to section 4.3.4 to answer
questions for his tank with no overfill protection.
                                                                      Chapter 3

Joe Completes The No Overfill Protection Section For His Used Oil Tank

Joe knows he needs to complete section 4.3.4 because the table at the beginning of 4.3
told him to fill out this section for his used oil tank, which has no overfill protection. He
reads the information about tanks with no overfill protection before he answers the
questions. The questions in section 4.3.4 are like the questions Joe answered for
overfill alarms and automatic shutoff devices.
 A copy of Joe's checklist and summary of compliance question are on the right hand
 page, so you can follow along. The next few paragraphs will tell you why he
 answered the questions the way he did.
Joe circles LIST 4 at the top of the checklist, since that is the only tank with no overfill
protection.  He does not circle the other tanks and will not answer any questions for
them.

Joe stores only used oil in this tank and he never puts in more than 25 gallons at one
time. So Joe answers yes to the question in the checklist.

At the bottom of the page, Joe reads the directions in the summary of compliance
question that tell him how to answer it.  Since he answered yes to the question above,
he answers yes to the summary of compliance question.

Joe is finished answering detailed questions about overfill protection for his tanks. He
is ready to answer the summary of compliance with overfill protection question at the
end of section 4.3. Joe turns the page and looks at the directions and the question.

Joe Answers The Summary Of Compliance With The Overfill Protection
Question

Joe turns to the page that contains the summary of compliance with overfill protection
question. First Joe reads the directions in the gray direction box at the top of the page.
Then he checks to make sure he has completed all the checklists required before he
answers the summary question. Joe filled out the overfill alarm checklist for USTs 1 and
2, the automatic shutoff device checklist for LIST 3,  and the no overfill protection
checklist for LIST 4.  Because he filled out a checklist for each tank, he is ready to
answer the summary question.
 A copy of Joe's summary of compliance question is on the right hand page, so you
 can follow along. The next few paragraphs will tell you why he answered the
 questions the way he did.
Joe reads the summary of compliance with overfill protection question. He knows that
he answered yes to the summary questions for the overfill alarms on USTs 1 and 2 and
for the no overfill protection for LIST 4. But he answered no to the summary of
compliance for the automatic shutoff device for LIST 2. So he answers no to the
summary of compliance with overfill protection, because he is not in compliance with all
overfill protection requirements for his tanks. He knows he has to fill out a return to
compliance plan form for the automatic shutoff device on LIST 2; however, his other
tanks are currently in compliance with overfill protection requirements.

Joe will copy his answer to this summary of compliance with overfill protection question
to his certification of compliance form in appendix A. He will answer no to question 3
on the certification of compliance form.

Joe is ready to move on to section 4.4 and the other sections of chapter 4, which he will
complete the same way as section 4.3.

Joe will continue through the rest of chapter 4 until he has completed all of the sections
that apply to the USTs at his facility. Then he will complete the certificate  of compliance
form in appendix A. Joe will mail this form along with the return to compliance form (if
necessary) to {state}.

Joe has finished the workbook. He will fix any problems and follow through with any
return to compliance plans he has filled  out.


   Now you are ready to fill out chapter 4 in this workbook. If you need help with this

Identifying The USTs At Your Facility
 Complete the table below to identify the USTs at your facility. To help you complete this
 workbook, each LIST at your facility is assigned a number (1, 2, 3, etc.) in the first column of
 the table. Use this LIST number consistently throughout this workbook. For questions
 about completing this table, consult the workbook example in section 3.4.
 •  The total number of USTs you identify should add up to the same number you calculated
    for question 4 in chapter 1 (including temporarily closed tanks).
 •  The Identification Number in the second column could be a common identification you use
    (for example: state tank registration number)
 •  The Other Identifying Information in the fifth column should contain information to help
    further identify each tank, such as:
    -   the location of the UST at your facility (for example: north, east, southwest, etc.)
    -   special  features of the UST (for example: the specific compartment of a
        compartmentalized tank, the specific tank in a manifolded tank system)
Special Instructions - The following are special considerations for cases where your facility
has one or more of the following conditions listed below.
•  More Than Five USTs At Your Facility Covered By This Workbook - You will need to
   make a copy of the table below. Change the UST numbers on your copy to show additional
   tanks (6, 7, 8, etc).  You will also need to make copies of the checklists in chapter 4 and
   renumber the UST numbers at the top of those lists as well.
•  Compartmentalized Tanks - A compartmentalized tank is a tank that has several
   separated  sections to contain different products.  Each section is called a compartment. If
   you have a compartmentalized tank, treat each compartment as a separate UST as you
   complete this workbook. Make sure to clarify which tank you are referring to in the Other
   Identifying Information column in the table below.
   Manifolded Tanks - Manifolded tanks are two or more tanks connected together by piping.
   These tanks contain the same product. The piping connecting the tanks allows the product
   to move from one tank to another as product is added or removed from one of the tanks. If
   you have manifolded tanks, treat each manifolded tank as a separate UST as you complete
   this workbook. Make sure to clarify which tank you are referring to in the Other Identifying
   Information column of the table below.
•  Temporarily Closed USTs - Temporarily closed  USTs do not have to meet the spill and
   overfill requirements  in sections 4.1 and 4.3. Section 4.11 contains requirements and best
   management practices for temporarily closed USTs.

                         Section 4.1:  Spill Protection
                Spill protection devices are used at fill pipes to catch drips and small spills
                that may occur when the delivery hose is disconnected from the fill pipe.
                Many spill protection devices are called spill buckets or catchment basins.
   Sample Spill Bucket/Cross-
   Section
Spill protection is typically not designed to contain
product for long periods of time.

Some spill protection devices are equipped with a drain
valve or manual pump which allows you to drain
accumulated product into your tank. Be aware that
when you drain the contents of a spill bucket into your
tank, water and debris may also enter the tank. If spill
protection is not equipped with a drain valve or pump,
any product or water in your spill bucket will need to be
removed manually and disposed of properly.
                Directions For Completing The Spill Protection Section
 Step 1:  Determine if you have spill protection. (If you do not know if you have spill
         protection, read the information below this box to determine whether or not it has
         been installed).

 Step 2:  Read the requirements and best management practices on the next page.

 Step 3:  Fill out the checklist for spill protection and complete the question at the bottom of
         the last page of this section that summarizes your compliance with spill protection.
Take the following steps to figure out what is at your facility:
   Lift each fill port lid and look to see if you have spill
   protection around your fill pipe.
   Look through your old records to check if you had spill
   protection installed.
•   Ask the contractor who installed your LIST.

Requirements And Best Management Practices For Spill Protection
  •     Any LIST that receives more than 25 gallons in a single delivery must have spill
  J     protection at each fill port where product delivery could occur.
         Spill protection must prevent the release of product to the environment when the
         transfer hose is detached from the fill pipe. The spill protection cannot meet this
         requirement if it is not able to contain liquid or if it is full of liquid or solid debris when
         the tank is being filled.

              Periodically check to see if your spill protection will hold liquid.

              Periodically inspect your spill protection for signs of wear, cracks, or holes.

              Make sure your spill protection is empty of liquid and debris before and after
              each delivery.
         Even though tanks that never receive deliveries of more than 25 gallons of product
         at a time are not required to have spill protection, you should consider using spill
         protection as part of good LIST system management. Many used oil tanks fall into
         this category.
                                                                             Chapter 4

                     Section 4.2:  Correct Filling Practices

Requirements And Best Management Practices For Correct Filling Practices

          As an owner or operator, you are responsible for any releases of product that occur
          due to spilling or overfilling during product delivery.

          •   You must make sure the amount of product to be delivered will fit into the
              available empty space in the tank.

          •   You must make sure the transfer operation is monitored constantly to prevent
              overfilling and spilling.
          A good management practice that will help you meet the correct filling practice
          requirements is to make sure the activities below are performed each time you have
          product delivered to your tank.  The table below describes activities to perform
          before, during, and after product delivery.
                Activities To Perform Before, During, And After Product Delivery
 What To Do
 Before Your
 Tanks Are
 Filled
• •  Determine and record accurate readings for product and water in the tank before
    product delivery.
• •  Order only the quantity of product to fill 90 percent of the tank. Remember, the
    formula for determining the amount of product to order is:

  [tank capacity (gallons) X 90% ] — gallons of product in tank now = amount to order

 Example: You have a 10,000 gallon tank and currently have 2,000 gallons in the tank.
        (10,000 gal X  0.9  ) — 2,000 gal = 7,000 gal (amount to order)

• •  Make sure the delivery person knows which type of overfill device is on the tank
    and what actions to perform if it activates. One way to do this is to post a copy of
    the appropriate sign provided in appendix G where the delivery person will see it.
• •  Review and understand the spill response procedures.
• •  Make sure the spill bucket is empty, clean, and will contain spills.
 What To Do
 While Your
 Tanks Are
 Being Filled
    Have an accurate tank capacity chart available for the delivery person.
    Have a person responsible for monitoring the delivery available each time tanks
    are being filled. The delivery person makes all hook-ups. The person monitoring
    the delivery should be prepared to stop the flow of product from the truck to the
    tank at any time and respond to any unusual condition, leak, or spill.
    Make sure spill response supplies are available in case a spill or overfill occurs.
    Make sure there are safety barriers around the delivery area.
    Make sure there is adequate lighting around the delivery area.
 What To Do
 After Your
 Tanks Are
 Filled
    Have a person available to monitor the disconnection of hook-ups following
    delivery. The delivery person disconnects the hook-ups.
    Determine and record accurate readings for product and water in the tank after
    delivery.
    Verify the amount of product received.
    Make sure fill ports are properly secured.
    Make sure the spill bucket is free of product and clean up any small spills.

                      Section 4.3:  Overfill Protection
            Overfill protection equipment installed on USTs helps prevent your tanks from
            being overfilled during product delivery.  Overfill protection is designed to stop
            product flow, reduce product flow, or alert the delivery person during delivery
            before the tank becomes full and begins releasing product into the environment.

            There are three common types of overfill protection:
               overfill alarms
               automatic shutoff devices
               ball float valves
              Directions For Completing The Overfill Protection Section
Step 1:  Fill out the table on the next page to identify the type of overfill protection you have
        for each UST.

        •    Different tanks at your facility may have different types of overfill
             protection.  Make sure to select the appropriate type of overfill
             protection for each tank at your facility.

             Some of your tanks may have more than one type of overfill protection.
             Only choose one type of overfill protection for each tank for this
             workbook. You only need to meet the requirements for one type of
             overfill protection for each tank.

Step 2:  For each type of overfill protection you checked in the table, go to the
        corresponding section listed in the far-right column. Read the requirements and
        best management practices and fill out the appropriate checklist(s) in that section.
        You may need to go to more than one section and fill out more than one checklist -
        each overfill protection type has a separate checklist.

Step 3:  Once you have completed the checklists for all of your overfill protection type(s),
        turn to  the last page of this section and complete the question that summarizes your
        compliance with overfill protection.
                                                                           Chapter 4

Section 4.3.4
 Take the following steps to figure out what is at your facility.
 •  Read the descriptions below to determine if you have overfill protection.
 •  Look through your old records to see if you had overfill protection installed.  Check for the
   names of the overfill protection type.
 •  Ask the contractor who  installed your LIST.
 Descriptions Of Different Types Of Overfill Protection

 Overfill Alarms - An overfill alarm has a sensor in the tank.
 The sensor is typically connected to a monitoring device such
 as an automatic tank gauge (ATG). An overfill alarm provides
 a warning that can be seen or heard (or both) by the person
 delivering the product when the tank is close to being full.

Automatic Shutoff Devices - An automatic shutoff device is located at the fill pipe of your
tank.  Look down your fill pipe  to see part of this device. You will see what appears to be a line
cutting through your fill pipe (or a half moon shape in your fill pipe).

                           Ball Float Valves -
A ball float valve is located inside the tank where
the vent line exits the tank. You might find it
difficult to determine whether or not you have this
device because of where it is located. You might
be able to find an extractor port for the ball float
valve (see picture below). Otherwise, you will
need to look through your paperwork to
determine whether your tank has this device; or
you should ask the contractor who installed your
tanks.

 4.3.1 Overfill Alarms
            Overfill alarms send a warning that can be seen or heard by the person
            responsible for monitoring the delivery of product to your tank. The warning
            activates when the LIST is approaching tank capacity and warns the delivery
            person to stop delivery.  When the alarm activates, the delivery person should
            immediately stop the flow of product to the tank.
Requirements And Best Management Practices For Overfill Alarms

  £H|   You must have overfill protection (for example, an overfill alarm) for every LIST that
  I      is filled with more than 25 gallons of product at one time.
         The overfill alarm must activate when the product in the tank reaches 90 percent of
   f     the tank capacity or is within one minute of being overfilled.
         The overfill alarm must be located so it can be seen and/or heard from where the
         LIST is filled.  This ensures that the person responsible for monitoring the delivery
         will know when the tank is almost full.
         A qualified LIST contractor should periodically check your overfill alarm to make sure
         it is functioning properly.
         You should inform your delivery person you have an overfill alarm.

         •  You could place a durable sign near each fill pipe. The sign should be in clear
            view of the delivery person. It should say there is an overfill alarm for this tank,
            what occurs when the alarm activates, and indicate the necessary actions to
            take. See the sample sign in appendix G as a reference.
                                                                             Chapter 4

 4.3.2  Automatic Shutoff Devices
             The automatic shutoff device slows down and stops the flow of product during
             delivery when the product has reached a certain level in the tank.
Requirements And Best Management Practices For Automatic Shutoff Devices
          You must have overfill protection (for example, an automatic shutoff device) for every
   •      LIST that is filled with more than 25 gallons of product at one time.
          Automatic shutoff devices must activate when the product in the tank reaches 95
          percent of the tank capacity or before the fittings at the top of the tank are exposed
          to product.
             There must not be anything in the fill pipe that would keep the shutoff mechanism
             from working properly.

             The automatic shutoff device must be placed so the float arm is not blocked and
             can move through its full range of motion.
          A qualified LIST contractor should periodically check your automatic shutoff device to
          make sure it is functioning properly.
          You should inform your delivery person you have an automatic shutoff device.

          •   You could place a durable sign near each fill pipe.  The sign should be in clear
             view of the delivery person. It should say there is an automatic shutoff device
             for this tank, what occurs when the device activates, and indicate the necessary
             actions to take. See the sample sign in appendix G as a reference.
          You should not use an automatic shutoff device for overfill protection if your tank
          receives pressurized deliveries because it might create dangerous situations (such
          as pressure building up in the tank) and result in gasoline spraying onto the delivery
          person or into the environment.
                                                                             Chapter 4

 4.3.3 Ball Float Valves
              The ball float valve (also called a flow vent valve) is installed at the vent line in
              the tank. The valve restricts vapor flow from the LIST as the tank gets close to
              full. As the tank fills, the ball in the valve rises, restricting the flow of vapors out
              of the LIST during delivery.  The flow rate of the delivery will decrease noticeably
              and should alert the person responsible for monitoring the delivery to stop the
              delivery.

Requirements And Best Management Practices For Ball Float Valves

          You must have overfill protection (for example, a ball float valve) for every LIST that
          is filled with more than 25 gallons of product at one time.
          Ball float valves must begin restricting vapor flow out of the tank when product in the
          tank reaches 90 percent of tank capacity or at least 30 minutes before the tank will
          be overfilled. For ball float valves to work properly:

          •  the air hole in the ball float valve must be open,
          •  the ball cage must be intact,
          •  the ball must move freely in the cage,
          •  the ball must seal tightly on the pipe, and
          •  the top of the tank must be air tight during delivery so vapors cannot escape from
             the tank. Everything in the tank (such as other tank access ports, fittings, and
             drain mechanisms on spill buckets) must be tight and able to hold the pressure
             created when the ball float valve engages.

          A qualified LIST contractor should periodically check your ball float valve to make
          sure it is functioning properly.

          You should inform your delivery person you have a ball float valve.

          •  You could place a durable sign near each fill pipe. The sign should be in clear
             view of the delivery person.  It should say there is a ball float valve for this tank,
             what occurs when the device activates,  and indicate the necessary actions to
             take. See the sample sign in appendix G as a reference.

          You should not use a ball float valve for overfill protection if any of the following
          conditions apply because you could create overfills or dangerous situations (such as
          pressure building up in the tank) and result in gasoline spraying onto the delivery
          person or into the  environment.

          Do not use ball float valves if:
          •  Your LIST receives pressurized deliveries
          •  Your LIST has suction piping
          •  Your LIST has coaxial stage I vapor recovery

Requirements And Best Management Practices For USTs With No Overfill Protection
          An LIST that is never filled with deliveries of more than 25 gallons of product at one time
          does not need overfill protection. You must have overfill protection for every
          LIST that is filled with more than 25 gallons of product at one time.
          Consider using overfill protection for USTs that never receive deliveries of more than
          25 gallons of product at one time. Overfill protection is part of good LIST system
          management.

              Section 4.4:  Corrosion Protection For Tanks
            All of your regulated tanks that are underground and routinely contain product
            must be protected from corrosion.

     You can protect your underground tanks from corrosion in several ways.  Your tanks
     may be:

         made of fiberglass reinforced plastic (FRP),
         steel that is coated and cathodically protected,
         steel that is jacketed or clad with a non-corrodible material (such as fiberglass),
         steel that is cathodically protected and/or internally-lined (this option is only allowed
         for older tanks installed on or before December 22, 1988), or
         metal without additional corrosion protection (if specific criteria are met).

     Internal lining and cathodic protection require periodic operation and
     maintenance activities.

         All underground tanks installed after December 22, 1988 need to meet all
         appropriate construction standards and must be installed according to a standard
         code of practice and manufacturer's instructions.

         All tanks must be made of or lined with materials that are compatible with the
         substance stored in the LIST.
         Keep all paperwork related to your corrosion protected tanks (examples include
         paperwork related to: installation, cathodic protection, integrity assessment, repair,
         and internal lining).

        Directions For Completing The Corrosion Protection For Tanks Section

Step 1:   Fill out the table on the next page to identify the type of tank you have for each
         UST.

         If you have compartmentalized tanks, treat each compartment as a separate UST.
         If you have manifolded tanks, treat each tank as a separate UST.

Step 2:   For each type of tank you checked in the table, go to the corresponding section
         listed in the far-right column.  Read the requirements and best management
         practices and fill out the appropriate checklist(s) in that section. You may need to
         go to more than one section and fill out more than one checklist - each tank type
         has a separate checklist.

Step 3:   Once you have completed the checklists for all of your tank types, turn to the last
         page of this section and complete the question that summarizes your compliance
         with tank corrosion protection.
                                                                           Chapter 4

•   Ask the contractor who installed your tank.

Tank Type Descriptions

Fiberglass Reinforced Plastic (FRP) Tank - This tank is made of fiberglass reinforced plastic.
Examples of current and past FRP tank makers include Owens Corning, Xerxes, Cardinal, Fluid
Containment, and Containment Solutions.

Jacketed  Steel Tank - This is a steel tank that is encapsulated (or jacketed) in a non-
corrodible, nonmetallic material such as fiberglass or polyethylene. This tank is secondarily
contained. There is a space between the steel wall and the jacket material.  This space may be
monitored for a breach of either the inner wall or outer jacket.  Examples of jacketed tank
brands include: Permatank®, Glasteel II®, Titan®, Total Containment®, and Elutron®

Clad Steel Tank - This tank is a steel tank that has a thick layer of non-corrodible material such
as fiberglass or urethane that is mechanically bonded (clad) to the outside of the steel tank.
This cladding helps protect the outside of the steel wall from corroding. Examples of clad tank
brands include: ACT-100®, ACT-100-U®, Glasteel®, and Plasteel®

-------
Coated And Cathodically Protected Steel Tank - This is a steel tank that has both an external
coating and cathodic protection.  An example of a coated and cathodically protected tank brand
is the sti-P3® tank. This type of tank is usually installed with galvanic (sacrificial) anodes for
cathodic protection.  However, these tanks may have an impressed current cathodic protection
system if the galvanic (sacrificial) anodes no longer protect the tank from corrosion.  If you are
not sure whether you have a cathodic protection system, see the Determining If You
Have Cathodic Protection section below.

Cathodically Protected  Steel Tank - This is a steel tank that has a cathodic protection system
but does not have an external coating. Typically, this type of tank was originally installed as a
bare steel tank before December 22, 1988 and had cathodic protection installed at some later
date. Tanks installed after December 22, 1988 are required to be both coated and cathodically
protected.  Usually this type of tank will have an impressed current cathodic protection system.
If you are not sure whether you have a cathodic protection system, see the Determining If
You Have Cathodic Protection section below.

Internally-Lined Steel Tank - This is a steel tank with an internal lining.  Typically, this type of
tank was originally installed as a bare steel tank before December 22, 1988 and had an internal
lining installed at some later date.

Internally-Lined And Cathodically Protected Steel Tank - This is a steel tank that has both
an internal lining and cathodic protection. Typically, this type of tank was originally installed  as
a bare  steel tank before December 22, 1988 and had cathodic protection and internal lining
installed at some later date. Usually this type of tank will have an impressed current cathodic
protection system. If you are not sure whether you have a cathodic protection system,  see
the Determining If You Have Cathodic Protection section below.

Metal Tank With No Additional Corrosion Protection - This is a tank made of metal such  as
steel or copper. It does not have cathodic protection, internal lining, or any non-corrodible
material that encapsulates or bonds to the outside of the tank.

Determining If You  Have Cathodic Protection - There are two types of cathodic protection
systems commonly used to protect your steel tank from corrosion - impressed current and
galvanic (sacrificial)  anodes.

Impressed Current  System - If you have an
impressed current system, you will have  a rectifier
(a device for converting alternating current into
direct current) located somewhere at your facility.

                                                 Sample Rectifier
Galvanic (Sacrificial) Anode System -  It is more
difficult to tell if you have this type of cathodic protection system
because the anodes are  buried and attached to the tank. You cannot
see the anodes and  there is no rectifier.  Look at any installation
paperwork you have or ask the contractor who installed the tank or
cathodic protection system to determine  if you have a galvanic
(sacrificial) anode system.  For example, a sti-P3® tank commonly uses
a galvanic (sacrificial) anode system.

 4.4.1: Fiberglass Reinforced Plastic Tanks, Jacketed Steel Tanks, And Clad Steel
 Tanks
              Fiberglass reinforced plastic (FRP) tanks, jacketed steel tanks, and clad steel
              tanks meet the corrosion protection requirements without additional equipment
              or operation and maintenance.
Best Management Practices For Fiberglass Reinforced Plastic Tanks
       Have your fiberglass reinforced plastic tanks
       periodically checked for deflection (deflection is a
       measure of the roundness of your tank). Since
       these tanks are made from materials considered to
       be sensitive to flexing, over deflection may result in
       cracking and  a leak. Allowable deflections vary
       with tank diameters and may be measured by
       following the  manufacturer's installation checklist.
Sample FRP Tank
Best Management Practices For Jacketed Steel Tanks

       Have your jacketed steel tanks periodically tested by a qualified contractor to make sure
       the space between the steel tank and secondary jacket is tight.  This space is known as
       the interstitial space or secondary
       containment area.  If your primary
       tank wall would leak and the
       secondary containment jacket was
       not tight, a release could get into the
       environment and result in cleanup
      that could be costly and time-
      consuming.

Best Management Practices For Clad Steel Tanks

       Some clad steel tanks may also have cathodic
       protection. If you have clad steel tanks that have

       protection system tested periodically to make sure it is
       operating properly.

  4.4.2: Coated And Cathodically Protected Steel Tanks
              This type of tank has both a coating and cathodic protection on the outside wall
              of the tank. The coating is typically applied to the tank at the factory.  The
              cathodic protection may be either impressed current or galvanic (sacrificial)
              anodes. See section 4.4.3 if you have a steel tank that is cathodically
              protected but is not coated.
Requirements For Coated And Cathodically Protected Steel Tanks

          The coating must be made of a suitable dielectric material (a material that isolates
          the tank from the surrounding soil and does not conduct electricity). Coal tar epoxy,
          urethane, and isophthalic polyester resins are examples of generic types of coatings
          used on coated and cathodically protected steel tanks.
          You must comply with specific testing and record keeping requirements for cathodic
          protection.  Descriptions of cathodic protection, requirements and best management
          practices, and checklists for cathodic protection are in section 4.6. Before
          completing the checklist on the next page, you will need to read the cathodic
          protection section and fill out the checklists in that section.
An example of a commonly used coated and cathodically protected steel tank is the sti-P3®
tank.  This tank has a dielectric coating on the outside and has galvanic (sacrificial) anodes
attached to the outside of the tank. You may have had impressed current added to your sti-PS18
tank at some time in the past - this tank is still considered to be coated and cathodically
protected.

                 be either impressed current or galvanic (sacrificial) anodes.  See section
                 4.4.2 if you have a steel tank that is coated and cathodically protected.

Requirements And Best Management Practices For Cathodically Protected Steel Tanks

          Only steel tanks that were installed on or before December 22, 1988 may use cathodic
          protection without a dielectric coating to comply with the corrosion protection
          requirements. If you have a coated and  cathodically protected steel tank, go  to
          section 4.4.2.

          An integrity assessment of the tank must have been conducted before adding
          cathodic protection. Examples of methods of integrity assessment of a steel tank
          include:

          •  An internal inspection of the tank - a trained professional enters your tank to
             determine if it is structurally sound and free of corrosion holes.
          •  A video camera inspection of the tank combined with checking soil
             characteristics around the tank- the tank is emptied and a trained professional
             places a video camera into the fill ports of a tank to determine if the tank has any
             holes. The professional  also takes some soil measurements to determine the
             corrosive characteristics of the soil around your tank. All of the information is
             used to  determine whether the tank is structurally sound and free  of corrosion
             holes.
          •  A detailed site evaluation is performed at your facility - a trained professional
             evaluates the site characteristics and places the information into a model  that
             statistically determines the time it would take a steel tank to corrode through at
             that specific location.  This information is compared to the age of the tank to
             statistically determine whether the tank is structurally sound  and free  of corrosion
             holes.
          A code of practice must be followed when adding cathodic protection to a tank.
          You must comply with specific testing and record keeping requirements for
          cathodic protection.  Descriptions of cathodic protection, requirements and best
          management practices, and checklists for cathodic protection are in section 4.6.
          Before completing the checklist on the next page, you will need to  read the
          cathodic protection section and fill out the checklists in that section.

          Keep records of your integrity assessment and cathodic protection installation.
          These records  may be useful in determining whether your tank is in compliance with
          the corrosion protection requirements.

 4.4.4: Internally-Lined Steel Tanks
     nformation
This tank is made of steel and has a lining attached to the inside wall of the
tank.  See section 4.4.5 if you have a steel tank that is internally-lined and
cathodically protected.
Requirements And Best Management Practices For Internally-Lined Steel Tanks
          Only steel tanks that were installed on or before December 22, 1988 may use
          internal lining alone to comply with the corrosion protection requirements.
          If any repairs are performed when your tank is internally-lined, you must keep all
          records of those repairs for the life of the tank.
          A code of practice must be followed when adding an interior lining to a tank.
          Within 10 years of lining, lined tanks must be internally inspected by a qualified
          contractor and found to be structurally sound with the lining still performing in
          accordance with original design specifications. After the initial 10 year inspection,
          these inspections must be conducted at least every 5 years.

          Keep records of your lining installation and lining inspections. These records
          may be useful in determining whether your tank is in compliance with the corrosion
          protection requirements.

          Even though a tank that has internal lining is not required to have external corrosion
          protection, you should  consider adding cathodic protection as part of good  LIST
          system management. Note that if you add cathodic protection on your internally-lined
          tank, you must meet the inspection and testing requirements in section 4.6.

 4.4.5: Internally-Lined And Cathodically Protected Steel Tanks
    nformation
This tank is made of steel, has a lining attached to the inside wall of the tank
and cathodic protection on the outside wall of the tank. The cathodic protection
may be either impressed current or galvanic (sacrificial) anodes.
Requirements And Best Management Practices For Internally-Lined And Cathodically
Protected Steel Tanks

          Only steel tanks that were installed on or before December 22, 1988 may use the
          combination of an internal lining and cathodic protection without a dielectric coating
          to comply with the corrosion protection requirements. If you have a coated and
          Cathodically protected steel tank, go to section 4.4.2.
          When you combine the use of internal lining and cathodic protection, you must
          meet specific testing and record keeping requirements for cathodic protection, which
          are in section 4.6.  Before completing the checklist on the next page, you will
          need to read the cathodic protection section and fill out the checklists in that
          section.
          You must also meet the lining requirements in section 4.4.4. Before completing the
          checklist on the next page, you will need to read the internally-lined steel tank
          section and fill out the checklist in that section.

          You do not need inspections of the lined tank if both of the following apply to your
          lined and Cathodically protected tank:

          •   the integrity of the steel tank was ensured when cathodic protection was
             installed, and
          •   the method of integrity assessment determined the steel tank shell was
             structurally sound and free of corrosion holes.

          Examples of integrity assessments are provided in section 4.4.3.
          Have your internal lining checked periodically even if the inspections are not
          required.
          Keep records of your integrity assessment, lining, and cathodic protection
          installations. These records may be useful in determining whether your tank is in
          compliance with the corrosion protection requirements.

 4.4.6: Metal Tanks With No Additional Corrosion Protection
               Buried metal tanks with no additional corrosion protection are not commonly
               used to meet the tank corrosion protection requirements.  However, if your
               tanks meet the criteria below, this option may be used.
Requirements For Metal Tanks With No Additional Corrosion Protection

          If you have a regulated underground metal tank without additional corrosion
   f      protection, you must either:

             have the record of a corrosion expert's determination that your LIST site is not
             corrosive enough to cause the tank to have a release due to corrosion during
             the operating life of the tank, or

             have evidence to indicate {state} made a determination the tank construction and
             corrosion protection were designed to prevent the release or threatened release
             of any stored product.
        It is unusual to have a metal tank without additional corrosion protection.

              Section 4.5:  Corrosion  Protection For Piping

            All of your regulated piping that is in contact with the ground and routinely
            contains product must be protected from corrosion - this piping is often
            underground or buried. Note: fill pipes and vent lines do not usually need
            corrosion protection because these components do not routinely contain product.

            You can protect your piping from corrosion in several ways. It may be:
               made of a non-corrodible material (such as fiberglass or flexible plastic),
               steel that is coated and cathodically protected,
               metal that is cathodically protected (this option is only allowed for older piping
               that was installed on or before  December 22,  1988), or
            •   metal without additional corrosion protection (if specific criteria are met).

            Cathodic protection requires periodic operation and maintenance.

        All of your piping that is in contact with the ground and routinely contains product that
        was installed after December 22, 1988 needs to meet all appropriate construction
        standards and be installed according to a standard code of practice and the
        manufacturer's instructions.

        All of your underground piping must be made of or lined with materials that are
        compatible with the substance that is stored in the UST.
         Keep all paperwork related to your corrosion protected piping (examples include
         paperwork related to: installation, cathodic protection, and repair).

       Directions For Completing The Corrosion Protection For Piping Section
Step 1:  Fill out the table on the next page to identify the types of piping you have for each
        UST.

             Your UST may have different types of piping.  For example, part of the
             piping that goes from the tank to the  dispenser may be made of
             nonmetal and part of it may be made  of metal.  In addition, you may have
             piping that goes from one tank to another (such as piping between
             manifolded tanks).  Make sure that you select all types of piping
             associated with each UST.

Step 2:  For each type of piping you checked in the table, go to the corresponding section
        listed in the far-right column. Read the requirements and best management
        practices and fill out the appropriate checklist(s) in that section.  You may need to
        go to more than one section and fill out more  than one checklist - each piping type
        has a separate checklist.

Step 3:  Once you have completed the checklists for all of your piping types, turn to the last
        page of this section and complete the question that summarizes your compliance
        with piping corrosion protection.
                                                                           Chapter 4

If your piping type is not listed above, contact {state} to determine what you must do.

Take the following steps to figure out what is at your facility.
   Read the descriptions below to determine which types of piping you have.
   Look in your dispenser sumps and turbine sumps (these are areas under your dispenser
   and above your tank where piping and other equipment are located) to see if you can
   identify the piping. Some piping  may have metal flexible connectors in these areas. Look
   for the piping beyond the metal flexible connectors.
   Look through your old records to see if they match any of the names in the descriptions.
•   Ask the contractor who installed your piping.
Piping Type Descriptions

Fiberglass Reinforced Plastic (FRP) Piping - This piping is
nonmetal and is made of fiberglass reinforced plastic. It is a
rigid piping (not flexible). Examples of FRP piping makers
include Ameron and Smith Fiberglass Products Inc.  This piping
type may also have metal connectors associated with it.
                                                               Sample FRP Piping
Coated And Cathodically Protected Steel Piping - This is steel piping that has both an
external coating and cathodic protection. If you are not sure whether you have a cathodic
protection system, see the Determining If You Have Cathodic Protection section on the
next page.

Section 4.5

-------
Cathodically Protected Metal Piping - This is metal piping without an external coating that has
a cathodic protection system. Typically, this type of piping was originally installed as a bare
metal before December 22, 1988 and had cathodic protection installed at some later date.
Piping installed after December 22, 1988 must be both coated and cathodically protected.  If
you are not sure whether you have a cathodic protection system, see the Determining If
You Have Cathodic Protection section below.

Metal Piping With No Additional Corrosion Protection - This is metal piping that does not
have any additional corrosion protection.

Flexible Plastic Piping - This type of piping is made of plastic that is flexible.  Examples of
nonmetal flexible piping brand names include: Poly-Tech, Dualoy 3000, EnviroFlex, GeoFlex,
Perma-Flexx, Omniflex, and Co-Flex™. This piping type may also have metal connectors
associated with it.

Determining If You Have Cathodic Protection

There are two types of cathodic protection systems commonly used to protect your metal piping
from corrosion - impressed current and galvanic (sacrificial) anodes.

Impressed Current System - If you have an impressed current system, you will have a rectifier
(a device which converts alternating current into direct current) located somewhere at your
facility. Sample pictures of rectifiers are provided in section 4.4.

Galvanic (Sacrificial) Anode System - It is more difficult to tell if you have this type of cathodic
protection system because the anodes are buried and attached to the piping.  You cannot see
them and there is no rectifier. Look at any installation paperwork you have or contact the
contractor who installed the piping or cathodic protection system to try to determine if you have
a galvanic (sacrificial) anode system.

              requirements without additional equipment or operation and maintenance.
              However, these types of piping may have metal joints and connectors that are in
              contact with the ground and routinely contain product.  These metal components
              must be protected from corrosion.
Requirements For Fiberglass Reinforced Plastic (FRP) Piping And Flexible Plastic Piping

          Any metal piping components associated with these types of piping that are in
          contact with the ground and routinely contain product, such as turbine pump heads,
          metal flexible connectors, and metal swing joints must be protected from corrosion
          by one of the following:

             Isolating the metal component from direct contact with the ground (for example:
             by putting a protective covering or boot on a flexible connector or by moving the
             soil so it is not in contact with the metal component).

             Cathodically protecting metal components in contact with the ground.  If you
             cathodically protect the metal component, you must meet the cathodic protection
             requirements in section 4.6. Before completing the checklist on the next
             page, you will need to read the cathodic protection section and fill out the
             checklists  in that section.

                      Section 4.6: Cathodic Protection
            Cathodic protection is one option for meeting the corrosion protection
            requirements for metal tank and piping components that are in contact with the
            ground and routinely contain product. Components of your LIST that may have
            cathodic protection include: metal tanks, piping, and piping components such as
            turbine pump heads, flexible connectors, and swing joints.

            There are two types of cathodic protection: impressed current and galvanic (or
            sacrificial) anodes. They are described later in  this section.
             Directions For Completing The Cathodic Protection Section

Only complete this section if you are directed to do so by sections 4.4 or 4.5. If you
are not required to use cathodic protection to meet corrosion protection requirements
skip this section.

 Step 1:   Fill out the table on the next page to identify the type of cathodic protection you
          use for each tank and piping run.

Step 2:    Go to section 4.6.1 and read the requirements and best management practices
          and fill out the appropriate checklist in that section. If you have an impressed
          current cathodic protection system, you will be directed to complete section 4.6.2.
          Answer the questions in the checklists for both the tank and piping for each
          LIST that has cathodic protection.
               For example, a facility has a tank with impressed current cathodic protection
               and piping that is fiberglass with a buried metal flexible connector with a
               galvanic (sacrificial) anode. This LIST uses both an impressed current
               system and a galvanic (sacrificial) anode system for cathodic protection.
               For this example the reader would complete section 4.6.1 for both the tank
               and piping.  If the answer to a question in the checklist is no for either
               cathodic protection system (the system for the tank or the system for the
               piping) then the answer to that question will be no.  Since the tank has an
               impressed current system, the reader will also complete section 4.6.2 for the
               tank.

Step 3:    Once you have completed the checklists for each  LIST, go to the Summary Of
          Compliance With Cathodic Protection on the last page of this section and answer
          that question. This is the answer you will use for checklists in sections 4.4  and
          4.5.
                                                                           Chapter 4

Cathodic Protection Descriptions

Impressed Current Systems

An impressed current system uses a rectifier (a device for converting alternating current into
direct current) to provide direct current through anodes to the metal tank, piping, or other
underground components to achieve corrosion protection. The diagram below illustrates
impressed current cathodic protection.

How to tell if you have an impressed current system: You should have a rectifier located
somewhere at your facility. Impressed current cathodic protection systems are typically
installed in the field.

 Sample Impressed Current System Diagram
            Sample Rectifier
Galvanic (Sacrificial) Anode Systems

A galvanic (sacrificial) anode system uses anodes that are buried and attached to metal LIST
components for corrosion protection. The anode is more electrically active and will sacrifice
itself (corrode) to protect the metal component from corrosion. A sample picture of an anode
attached to a tank is shown on the right.

How to tell if you have a galvanic  (sacrificial)
anode system: It is more difficult to tell if you
have a galvanic anode system because you
typically cannot see the anodes and there is no
rectifier. The anodes are attached to the
underground component they are protecting and
are buried.  These anodes are usually installed
on tanks at the factory (such as on the sti-P3®
tank) and can be installed on piping  and other
underground metal components in the field. In
order to determine whether you have a galvanic
system, look at any installation paperwork you
might have or contact the contractor who
installed the cathodic protection system.

 4.6.1: Galvanic Anode And Impressed Current Cathodic Protection
Requirements And Best Management Practices For All Cathodic Protection Systems

           Your cathodic protection system must operate continuously to protect the metal
           tank and piping components in direct contact with the ground.
               If your cathodic protection system is disconnected or turned off, your
               underground LIST components are not protected from corrosion.
               Never turn off your rectifier and never disconnect a galvanic anode,
               unless contractors need to turn off or disconnect your cathodic protection for
               short periods during testing or for repairs.

           All  cathodic protection systems installed in the field must be designed by a
           corrosion expert.  Field installed means the cathodic protection system was not
           installed when the tank or piping was in the factory.  An example of a tank that has
           a factory installed cathodic protection system is the sti-P3® tank.
 A corrosion expert must meet specific qualifications. That person must be either:
    Certified by the NACE International, The Corrosion Society as a Corrosion Specialist or
    Cathodic Protection Specialist, or
    a registered Professional Engineer who has certification or licensing that includes
    education and experience in corrosion control of buried or submerged metal piping
    systems and metal tanks.	
          You must follow a code of practice when adding a cathodic protection system to your
          tank or piping.
          You must have your cathodic protection system tested periodically to make sure it is
          working properly.  The test must be conducted by a qualified cathodic protection
          tester within six months of installation and then at least every three years. In
          addition, if you have any repairs conducted to your cathodically-protected LIST, you
          must have a cathodic protection test conducted within six months of that repair.
          •   You must keep records of the last two cathodic protection tests.  A sample
             cathodic protection test record is in  appendix H.
             If your cathodic protection system does not pass the test, have your cathodic
             protection system evaluated and fixed by a corrosion expert.  Keep all records of
             the corrosion expert's evaluation and repairs to your cathodic protection system.
 A cathodic protection tester is a person who can demonstrate an understanding of the
 principles of all common types of cathodic protection systems as applied to buried or
 submerged metal piping and tank systems.	
          Keep all paperwork related to your cathodic protection system.

          Have cathodic protection tests conducted more frequently. The more often you have
          these tests conducted, the more likely you are to detect cathodic protection problems
          before releases occur.
                                                                              Chapter 4

 4.6.2:  Impressed Current Cathodic Protection - Additional Requirements And Best
        Management Practices
Additional Requirements And Best Management Practices For Impressed Current
Cathodic Protection Systems

          If you have an impressed current cathodic protection system, you must inspect the
          rectifier at least every 60 days to make sure it is on and operating properly.
          •   You must keep records of the last three inspections.  A sample impressed
             current inspection record keeping form is provided in appendix I.
             If your rectifier is not operating properly,  contact a corrosion expert to evaluate
             and fix your cathodic protection system.
Things To Do During Rectifier Inspections
1. Make sure the rectifier is
turned on.
Rectifiers always need to be on to protect your tank and
piping from corrosion. Never turn off your rectifier.
• your rectifier may have a light to indicate that it is
turned on
• your rectifier may have an on/off switch
Your rectifier should be directly wired to a dedicated circuit and not plugged into a wall outlet
or wired to a light switch.
2. Record the values from any
meters on the rectifier. If you
have ammeter and voltmeter
readings, compare them to
operating ranges established by
the corrosion expert.
Some rectifiers may have one or more of the following
meters:
direct current ammeter
direct current voltmeter
hour meter
The person who installed your impressed current system should have provided you with
paperwork to indicate what the normal operating voltage and amperage values are for your
cathodic protection system. If you do not have values for the normal operating voltage and
amperage, contact the person who installed the system and obtain that information.
3. If your rectifier does not appear to be operating properly (such as the rectifier or rectifier
light is not on or meter readings are not within established values), contact a qualified person
to fix the problem. Remember, only a corrosion expert can make changes to the design of
your cathodic protection system.
Warning You should not attempt to fix any problems with your rectifier. The rectifier poses
an electrical shock hazard.
Remember to keep all records of repairs and have a cathodic protection test conducted within
six months of any repair. Make sure the cathodic protection system passes the test.
       Perform inspections of your rectifier more frequently than every 60 days. The more
       often you  inspect the rectifier, the quicker you can detect problems with your cathodic
       protection system.

    Section 4.7:  Release Detection For Tanks

You have several options for meeting release detection (also called leak
detection) requirements for your tanks.  They include:
•   Automatic Tank Gauging
   Interstitial Monitoring (for tanks with secondary containment)
   Groundwater Monitoring
•   Vapor Monitoring
   Inventory Control and Tank Tightness Testing (a temporary method)
   Manual Tank Gauging (for small tanks)
   Manual Tank Gauging and Tank Tightness Testing (a temporary method for small tanks)
   Statistical Inventory Reconciliation (SIR)

Emergency generator tanks are not required to have release detection.

Requirements And Best Management Practices For All Tank Release Detection Methods
          You must keep records of release detection testing for at least one year.
          Your method of release detection must meet specific performance requirements.
          •   You must keep documentation from the manufacturer, vendor, or installer for at
             least five years which shows your release detection equipment can meet
             performance requirements.
                One way to obtain copies of this documentation is to access the National
                Work Group for Leak Detection Evaluations list. This list may be found at:
                http://www.nwglde.org

          Your release detection must be installed, calibrated, operated, and maintained
          according to the manufacturer's instructions.
             Keep all schedules of required calibration and maintenance provided by the
             equipment manufacturer for at least five years.
             Keep all records of calibration, maintenance, and repair for at least one year
             after the activity occurred.

          If you ever suspect or confirm a release, you must take appropriate action and, if
          necessary, report the release.  See section 4.9 for information on what to do.  Never
          ignore release detection alarms or failed leak detection tests. Treat them as
          potential leaks!

          If you have hazardous substance tanks (as defined under CERCLA), you must have
          secondary containment and use interstitial monitoring for release detection unless
          you have obtained a waiver from {state}.
                                                                         Chapter 4

-------
         Make sure your vendor or installer provides you with the information and training
         necessary to make sure your release detection equipment works effectively to detect
         leaks.
         Keep all of your records and paperwork for the life of the tank.
         Periodically have a qualified LIST contractor, such as the vendor who installed your
         release detection system, service your leak detection equipment according to the
         manufacturer's service instructions.
            Components can wear out and must be checked periodically.  Many vendors
            recommend or require this maintenance activity at least once annually.

         Make sure employees who run, monitor, or maintain the release detection system
         know how to run, monitor, or maintain the equipment and to whom to report
         problems. Develop and maintain regular training programs for all employees.
         Directions For Completing The Release Detection For Tanks Section
Step 1:   Fill out the table on the next page to identify the method of tank release detection
         you use for each tank.

            Different tanks at your facility may use different types of release
            detection. Make sure to select the appropriate type of release detection
            for each tank at your facility.

            Some of your tanks may have more than one type of release detection.
            Only choose one type of release detection for each tank for this
            workbook. You only need to  meet the requirements for one method of
            release detection for each tank.

Step 2:   For each type  of release detection you checked in the table, go to the
         corresponding section listed in the far-right column. Read the requirements and
         best management practices and fill out the appropriate checklist(s) in that section.
         You may need to go to more than one section and fill out more than one checklist •
         each release detection type has a separate checklist.

Step 3:   Once you have completed the checklists for all your methods of tank release
         detection, turn to the last page of this section and complete the question that
         summarizes your compliance with tank release detection.

Release Detection Descriptions

Automatic Tank Gauging (ATG) Systems -
An ATG system is a sensor permanently
installed in a tank and wired to a monitor to
provide information such as product level and
temperature. You should have a monitor
(sometimes called an ATG) mounted          	
somewhere at your facility. ATG system         Sample ATG Monitor   Sample ATG Monitor
monitors automatically calculate the changes
in product volume that can  indicate a leaking tank and can be set to activate an alarm when
there is a suspected problem with your tank.

Secondary Containment With Interstitial Monitoring - Secondary containment is an
additional barrier between the portion of an LIST that contains product and the outside
environment.  Hazardous substance tanks must have secondary containment with
interstitial monitoring or a waiver from {state}.  Examples of secondary containment include
the outer tank wall of a double-walled system, an excavation liner, and a bladder inside a tank.
The area between the inner and outer barriers is called the interstitial space and can be
monitored manually or automatically.  You may have interstitial monitoring ports on the
pavement at your facility.

You might perform interstitial monitoring by doing one of the following:
   manually checking the interstitial space for product or water.
   manually checking the interstitial space for the  appropriate liquid level (for interstitial spaces
   designed to be filled with liquid).
   manually checking a vacuum or pressure level  maintained in the interstitial space.
   electronic sensors in the interstitial space that are connected to and  monitored by electronic
   monitoring  equipment.

Groundwater  Monitoring -
Groundwater monitoring uses
monitoring wells placed around your
tank field to look for the presence of
liquid product floating on the
groundwater at the LIST site. You
should be able to see monitoring
well covers at your facility.  There
are two ways you can perform
groundwater monitoring:
                                     Sample Monitoring Well Cover

   Manual - use a bailing device (see picture above) to check each well
   for product at least once every 30 days.
   Bailing A
 Groundwater
Monitoring Well
   Electronic - use an electronic monitor at your facility connected to electronic sensors in the
   monitoring well that check for the presence of product at least once every
   30 days.

Vapor Monitoring - Vapor monitoring uses monitoring wells to look for the
presence of vapors in the soil at the LIST site.  Vapor monitoring will not work
well with product that does not easily vaporize (such as diesel fuel). You
should be able to see monitoring well covers at your facility. There are two
ways you can perform  vapor monitoring:

   Manual - use a hand-held device such as a photo-ionization detector
   (PID) or flame-ionization detector (FID) to check for vapors at each
   monitoring well at least once every 30 days.

   Electronic - use an electronic monitor at your facility connected to
   electronic sensors  in each monitoring well that check for the presence of
   vapors at least once every 30 days.
                                                                        Sample PID

Inventory Control And Tank Tightness Testing - This method involves measuring the
contents of the tank, recording the amount of product pumped each day, and reconciling that
data with measurements and records of product delivery. Typically, a measuring stick is used
to take the measurements.  This combined method also includes tightness testing every five
years.  This method may only be used for up to ten years after installing a new tank or
upgrading an existing tank with corrosion protection.
Manual Tank Gauging - Manual tank gauging alone may be used only for tanks of 1,000
gallons or less capacity. It involves taking your tank out of service for the testing period each
week, during which the contents of the tank are measured  at the beginning and end of the test
period. Typically, a measuring stick is used to take the measurements. The measurements are
then compared to weekly and monthly standards to determine if the tank is tight.
Manual Tank Gauging And Tank Tightness Testing - This method is for tanks of 2,000
gallons or less capacity. Manual tank gauging involves taking your tank out of service for the
testing period each week, during which the contents of the tank are measured at the beginning
and end of the test period. Typically, a measuring stick is used to take measurements. The
measurements are then compared to weekly and monthly standards to determine if the tank is
tight. This combined method also includes tightness testing every five years. This method
may only be used for up to ten years after installing a new tank or upgrading an  existing
tank with corrosion protection.
Statistical Inventory Reconciliation (SIR) - SIR is a method of release detection where
computer software is used to conduct a statistical analysis of inventory, delivery, and dispensing
data you collect every 30 days. A measuring stick or an ATG is commonly used to gather the
inventory data. Depending on the vendor, you may either have to send your data to the vendor
and receive a report or enter the data into a computer program  that provides you with the
results. The result of the analysis may be pass, inconclusive, or fail.

Requirements And Best Management Practices For
Automatic Tank Gauging
                                              Sample ATG
          Use your ATG system to test for leaks at least once every 30 days for each tank and
          keep a record of the result for at least one year. Your ATG system must be able to
          detect a 0.2 gallon per hour leak rate with at least a 95 percent probability of
          detection and no more than five percent probability of false alarm.
             Remember to test each tank.
             Make sure you are properly testing the portion of the tank that routinely contains
             product.
             Make sure the amount of product in your tank is sufficient to run the ATG leak
             test.  The tank must contain a minimum amount of product to perform a valid leak
             detection test (this information should be on the performance certification for
             your leak detection equipment).
          Test your tanks more frequently in order to catch leaks sooner. Testing more
          frequently will also help you ensure a valid test result each month.
          Frequently test your ATG system according to the manufacturer's instructions to
          make sure it is working properly.

             Read your owner's manual and run the appropriate tests to see if your ATG
             system is set up and working properly.
             Most ATG systems have a test or self-diagnosis mode that may run these
             checks.
          Periodically have a qualified LIST contractor, such as the vendor who installed your
          ATG, service all the ATG system components according to the manufacturer's
          service instructions.

          •   Tank sensors and other components can wear out and must be checked
             periodically. Many vendors recommend or require this maintenance activity at
             least once annually.

    4.7.2: Secondary Containment With Interstitial Monitoring
               Secondary containment is an additional barrier between the portion of an LIST
	   that contains the product and the outside environment. Examples of tank
               secondary containment include the outer tank wall of a double-walled system,
               an excavation liner, and a bladder inside  a tank. The area between the inner
               and outer barriers is called the interstitial  space and can be monitored to catch
               problems before product reaches the environment.  Hazardous substance
               tanks must have secondary containment with interstitial monitoring or a
               waiver from {state}.

Requirements And Best Management Practices For Secondary Containment With
Interstitial Monitoring

           Use your Interstitial monitoring system to test  for leaks at least once every 30 days
           for each tank and keep a record of the result for at least one year.
          Interstitial monitoring systems must be designed, constructed and installed to detect
          a leak from any part of the tank that routinely contains product.
             For double-walled tanks, the test method must be able to detect a release
             through the inner wall.
             For a secondary containment barrier in the excavation zone (for example an
             external liner), the following must be met:
             -  the barrier must be thick and impermeable (at least 10~6 cm/sec for the
                product stored),
             -  the barrier must be compatible with the product stored,
             -  the barrier must be installed so that it does not interfere with the proper
                operation of any cathodic protection system,
             -  groundwater, soil  moisture, or rainfall will not make the testing or sampling
                method inoperative so that a release could go undetected for more than 30
                days,
             -  a site assessment is conducted to make sure that the secondary barrier is
                always above the groundwater and not in a 25 year flood plain (unless the
                barrier and monitoring designs are for use under these conditions), and
             -  monitoring wells are clearly marked and secured.
             For tanks with internally fitted liners,  the automated device must be able to
             detect a release between the inner wall of the tank and the liner. The liner also
             must be compatible with the product stored.

          If you have an electronic  system, you should frequently test your interstitial
          monitoring system according to the manufacturer's instructions to  make sure it is
          working properly.

          If you have an electronic  interstitial monitoring system,  periodically have a qualified LIST
          contractor, such as the vendor who installed it, service all the system components
          according to the manufacturer's service instructions.
                                                                          Chapter 4

    4.7.3: Groundwater Monitoring
               Groundwater monitoring uses monitoring wells placed around your tank field to
ls	J  look for the presence of liquid product floating on the groundwater.

Requirements And Best Management Practices For Groundwater Monitoring

   ._   Test each monitoring well for leaks at least once every 30 days and keep a record
   •      of the result for at least one year.
          You must keep all of your groundwater monitoring ports clearly marked and secured.

          •   According to American Petroleum Institute Recommended Practice 1637,
             monitoring well covers should be marked with a solid white circle containing a
             solid black triangle.

          A site assessment must have been conducted at your facility to determine the
          following:
          •   the appropriate number and placement of monitoring wells so that any release
             from the UST will be detected,
             groundwater at your facility is never more than 20 feet below the surface,
          •   the hydraulic conductivity of the soil between your UST and the monitoring wells
             is not less than 0.1 cm/s (i.e., the soil should consist of gravels, coarse to
             medium sands, coarse silts, or other permeable materials),
          •   the product stored in your tank does not mix or blend with water,
          •   the slotted part of the well casing allows product to collect in the well, but does
             not allow surrounding soil to enter under both low groundwater and high
             groundwater conditions,
             monitoring wells are sealed from the ground surface to the top of the filter pack,
             monitoring wells are in the excavation zone or are as close to it as feasible, and
          •   the method used for detection can  determine the presence of at least one-eighth
             of an inch of free product on top of the water in the monitoring well.

          If you have an electronic system, you should frequently test your groundwater
          monitoring system according to the manufacturer's instructions to make sure it is
          working properly.

          If you have an electronic groundwater  monitoring system, periodically have a
          qualified UST contractor, such as the vendor who installed it, service all the system
          components according to the manufacturer's service instructions.

          Check your monitoring wells more frequently in order to catch leaks sooner.
                                                                          Chapter 4

    4.7.4: Vapor Monitoring
               Vapor monitoring uses monitoring wells to look for the presence of vapors in
               the soil at the LIST site. Vapor monitoring will not work well with a product
               such as diesel fuel that does not easily vaporize.
Requirements And Best Management Practices For Vapor Monitoring

          Use your vapor monitoring system to test for leaks at least once every 30 days and
          keep a record of the result for at least one year.
             Remember to check each monitoring well.
         You must keep all of your vapor monitoring ports clearly marked and secured.
          •   According to American Petroleum Institute Recommended Practice 1637,
             monitoring well covers should be marked with a solid white circle containing a
             solid black triangle.

          A site assessment must have been conducted at your facility to determine the
          following:
          •   the appropriate number and placement of monitoring wells so that any release
             from the UST will be detected,
          •   the materials used as backfill must be porous enough to readily allow vapor
             movement from a release (e.g., gravel, sand, crushed rock),
          •   the product stored in the tank or tracer compound can vaporize enough to be
             detected by the monitor,
          •   the measurement of vapors by the monitoring device is not made inoperative by
             groundwater, rainfall, soil moisture, or other interferences that would allow a
             release to go undetected for more than 30 days,
             background contamination in the excavation zone must not cause any
             interference, and
          •   vapor monitors are designed and operated to detect any significant increase in
             the concentration (above the background levels) of product stored in the tank, a
             component or components of that product, or a tracer compound placed in the
             tank system.
          If you have an electronic system, you should frequently test your vapor monitoring
          system according to the manufacturer's instructions to make sure it is working
          properly.

          If you have an electronic vapor monitoring system, periodically have a qualified UST

 4.7.5: Inventory Control And Tank Tightness Testing
Requirements And Best Management Practices For Inventory Control And Tank
Tightness Testing

          You may use this combination method for up to ten years after installing a new LIST
          or for up to ten years after your existing tank met the corrosion protection
          requirements.

          For inventory control you must do the following:
          •   Take inventory and dispenser readings and record the numbers at least once
             each day that product is added to or removed from your tank.
             Reconcile deliveries with delivery receipts by taking inventory readings before
             and after each delivery.
             Reconcile all of your data at least once every 30 days and record your results.
             Keep inventory records for at least one year.

          Your equipment (for example: a stick or electronic monitoring device) must be
          capable of measuring to the nearest one-eighth  inch and be able to measure the
          level of product over the full range of the tank's height.
              Check your measuring stick periodically to make sure you can read the
              markings and numbers, that the bottom of the stick is not worn, and that the
              stick is  not broken, bowed, or warped.

          You must make sure your product dispensers are calibrated according to local
          standards or to an accuracy of six cubic inches for every five gallons of product
          withdrawn.
              Look on your dispenser for a weights and measures sticker or contact your
              local department of weights and measures.

           You must measure the water in your tank to the nearest one-eighth inch at least
           once a month.
           •   You can use a paste that changes color when it comes into contact with water.
           You must have a tightness test conducted at least once every five years.
           •   The test may be conducted by a trained tester or by using a permanently
               installed electronic system.
               Make sure the method of tank tightness testing is certified for the types of tanks
               you have and for the product you store in those tanks.
           •   The tightness test must be capable of detecting a 0.1 gallon per hour leak rate
               from any portion of the tank that routinely contains product.
               Keep the results of your most recent tightness test.
            For more consistent stick measurements, have the same person stick the tank at
            the same time each day.
                                                                          Chapter 4

 4.7.7: Manual Tank Gauging And Tank Tightness Testing
Requirements For Manual Tank Gauging And Tank Tightness Testing
         Manual tank gauging combined with tank tightness testing is a temporary release
         detection method that may be used for up to 10 years after installing a new LIST or
         for up to 10 years after your existing tank met the corrosion  protection requirements.

         Only tanks of 2,000 gallons or less meeting the size and test requirements in the
         table below may use manual tank gauging combined with tank tightness testing.
         See section 4.7.6 if your tank is 1,000 gallons or less and you can use manual
         tank gauging only.

         You must perform weekly testing as follows:
         •   Take your tank out of service for the period of the test to ensure no product is
            added or removed.
            Record two inventory readings at the beginning and end of the test period.
            Reconcile the numbers weekly and keep records of the results.  For the tank to
            pass, the difference between the beginning and ending measurements cannot
            exceed the weekly standard value listed in the third column  of the table above.
            Instructions and a record keeping form are provided in appendix L.

         You must reconcile your records every four weeks to obtain monthly numbers. For
         the tank to pass, the difference between the average of the four weekly beginning
         and ending measurements cannot exceed the monthly standard value listed in the
         fourth column of the table above.  Instructions and a record keeping form are
         provided in appendix L.

         Your equipment (e.g., your measuring stick) must be capable of measuring to the
         nearest one-eighth inch and be able to measure the level of product over the full
         range of the tank's height.
            Check your measuring stick periodically to make sure you can read the markings
            and numbers, that the bottom of the stick is not worn, and that the stick is not
            broken, bowed, or warped.

         You must have a tightness test conducted at least once every five years.
         •   The test may be conducted by a trained tester or by using a permanently
            installed electronic system.
            Make sure the method of tank tightness testing is certified for the types of tanks
            you have and for the product you store in those tanks.
         •   The tightness test must be capable of detecting a 0.1  gallon per hour leak rate
            from any portion of the tank that routinely contains product.
            Keep the results of your most recent tightness test.

 4.7.8: Statistical Inventory Reconciliation
               Statistical Inventory Reconciliation (SIR) is a method of release detection
               where computer software conducts a statistical analysis of inventory, delivery,
               and dispensing data every 30 days. SIR must be able to detect a 0.2 gallon
               per hour leak rate with at least a 95 percent probability of detection and no
               more than 5 percent probability of false alarm or be approved by {state}.
               Depending on the vendor, you may either have to send your data to the
               vendor and receive a report or enter the data into a computer program  that
               provides you with the results. The result of the analysis may be pass,
               inconclusive, or fail.

Requirements And Best Management Practices For SIR

          You must supply inventory data to your SIR vendor (or enter your inventory data
          into a computer software program and generate your leak detection results)  at least
          once every 30 days. If you submit your data, a vendor will provide you with your
          leak detection results after the statistical analysis is completed.  Keep your SIR
          results for at least one year.
             Make sure the vendor provides your results quickly so you know whether or not
             your tank is leaking every  30 days.
             Check with your SIR vendor or computer software to determine what specific
             inventory data is necessary.

          If you receive an inconclusive result, you must correct the problem (the problem
          might be poor measurement techniques or something more serious such as a
          release) and document the results of the investigation.
          •   An inconclusive result means you have not performed leak detection for that
             month.

         Many vendors require you to measure product to the  nearest one-eighth inch (for
         example by using  a stick or electronic monitoring device) and that the equipment  be
         capable of measuring the level of product over the full range of the tank's height.
             If you have a measuring stick, check it periodically to make sure you can read
             the markings and numbers, that the bottom of the stick is not worn, and that the
             stick is not broken, bowed, or warped.
             For more consistent measurements, take measurements at the same time each
             day.

         If you use an automatic tank gauge to gather inventory data, periodically have a
         qualified  LIST contractor, such as the vendor who installed it, service all the system
         components according to the manufacturer's service  instructions.

         Make sure your product dispensers are calibrated according to local standards.
         Look on your dispenser for a weights and measures sticker or contact your local
         department of weights and measures.

          Periodically measure the water in your tank to the nearest one-eighth inch. You can
          use a paste on your measurement stick that changes color when it comes into
          contact with water.


                                                                         Chapter 4

                  Section 4.8: Release Detection For Piping
f           1   When looking at release detection requirements for piping, we must look at how
^—	   product is delivered through the piping. There are several types of product
              delivery systems for piping that could be used with underground storage tanks.
              A product delivery system is piping that delivers product from one tank to another
              tank or from a tank to a dispenser. Product delivery systems may be either
              pressurized or operate by suction. In addition, piping could either be above
              ground or underground.  The release detection requirements apply to piping
              delivery systems that are underground only.  The release detection requirements
              are different depending on whether the piping delivery system is pressurized or
              suction.

              If you have piping associated with an emergency  generator tank, then that piping
              is not required to have release detection.
           Directions For Completing The Release Detection For Piping Section
  Step 1:   Fill out the table on the next page to identify the type of product delivery piping you
           have for each LIST.

              Different piping at your facility may use different types of product delivery
              systems. Make sure to select the appropriate type of product delivery
              system for all of the piping at your facility.

              Do not include fill pipes or vent lines as part of your product delivery
              piping.

              The release detection requirements only apply to the parts of your piping
              that are  underground.  If all piping associated with an LIST is above
              ground, then that piping has no requirements for release detection.

  Step 2:   For each type of piping you checked in the table, go to the corresponding section
           listed in the far-right column.  Read the requirements and best management
           practices and fill out the appropriate checklist(s) in that section. You may need to
           go to more than one section and fill out more than one checklist.

  Step 3:   Once you have completed the checklists for all your types of product delivery
           piping, turn to the last page of this section and complete the question that
           summarizes your compliance with piping release detection.
                                                                             Chapter 4

Product Delivery System Descriptions
Pressurized product delivery pushes product from the
tank to the dispenser through piping.  Pressurized piping
delivery commonly uses a submersible turbine pump
(STP) located inside the tank.  You should be able to tell
if you have a pressurized piping system by looking for a
STP head in a sump above the tank.  These sumps are
usually covered with a lid and may also have a sump
cover under the lid. In rare cases, pressurized piping
delivery may be by gravity feed. Gravity feed  has no
pump and relies on the downward slope of the piping to
transport product.

Suction product delivery pulls product from the tank
to the dispenser through the piping by using a suction
pump located at the dispenser.  You should be able
to tell if you have suction piping by looking for a
suction pump (you may see pulleys and belts) inside
the dispenser. There will not be a STP pump head in
a sump above the tank.

 4.8.1: Pressurized Piping
Requirements For Pressurized Piping

          Pressurized piping must have an automatic line leak detector (LLD) installed. You
          must meet specific requirements for your LLDs. See section 4.8.1.1  for
          information and checklists for LLDs.

          Along with a LLD, each pressurized piping must have one of the following:

             monthly vapor monitoring
             monthly groundwater monitoring
                 If you are using groundwater or vapor monitoring for your tank, you  may be
                 using these methods for your piping too.
             monthly SIR - check your monthly SIR reports to see if this method is also being
             used for your piping.
             monthly interstitial monitoring - to use this method, your piping must be
             secondarily contained and you must be monitoring the interstitial space at least
             once every 30 days for releases. If you have a hazardous substance  LIST, you
             must either use  interstitial monitoring or have a waiver from  {state}.
             annual line tightness test - you must have a line tightness test conducted at
             least every 12 months  for pressurized piping.  See section 4.8.3 for information
             and checklists  for line tightness testing.
          If you use monthly groundwater monitoring (section 4.7.3), vapor monitoring (section
          4.7.4), or SIR (section 4.7.8), the requirements are the same for both tanks and
          piping.  Monitoring wells need to be placed appropriately to detect a release from all
          parts of the piping.

          If you use interstitial monitoring (section 4.7.2), the requirements are the same for
          both tanks and piping.  In addition, if you use sump sensors, you must ensure the
          following for interstitial monitoring for piping:
             Sensors are typically located in the turbine or dispenser sump areas for
             interstitial monitoring. These sumps must be tight and free of leaks for piping
             interstitial monitoring to operate correctly.
             -  Piping should slope to the sump containing the monitoring sensor.
             -  Make sure the rubber boot is pulled back from the outer wall of the piping so
                product will drain into the sump if a problem occurs.
             -  Make sure the sump does not have any water in it.
             -  Make sure the sensors are located near the bottom of the sump so they
                activate quickly when a release occurs.
                                                                             Chapter 4

 4.8.1.1: Automatic Line Leak Detectors
 Sample LLD
 Automatic line leak detectors (LLD) are devices
 designed to detect a catastrophic release from
 pressurized piping. Typically, they are located
 on the submersible turbine pump (STP) head in
 the sump above your tank.

There are two types of automatic LLDs:

   Mechanical LLDs are mechanically
   operated pressure valves that test for piping
   leaks each time the pump is turned on.
   Electronic LLDs have an electronic
   detection element that connects to an
                                                             Sample STP Head With
                                                                      LLD
                  electronic control panel and monitors for piping releases.
Some interstitial monitoring devices may also serve as LLDs or an electronic LLD may also be
able to conduct a line tightness test.  Check with {state} to see if these options apply to you.

Requirements And Best Management Practices For Automatic Line Leak Detectors

          Pressurized piping must have a LLD installed that can detect a release of three
          gallons per hour at a line pressure of ten pounds per square inch within one hour.

          When a leak is detected, automatic LLDs must either:
             shut off product flow;
             restrict product flow; or
          •  trigger an alarm that you can see or hear.

          You must have a test conducted that demonstrates proper functioning on each LLD
          at least every 12  months. The test must be performed according to the
          manufacturer's instructions.
          •  You must keep a record of the LLD tests for  at least one year.

          You must have all records of any calibration, maintenance, or repair of your LLDs
          that were performed in the last 12 months.
          If you have LLDs that are less that five years old, you must have all records of
          performance claims, as well as calibration and maintenance schedules.
          Make sure your LLDs are designed to operate with the type of product your LIST
          stores.  For example, some LLDs are designed to work with gasoline, while others
          are intended to work with diesel.

 4.8.2: Suction Piping
Requirements For Suction Piping

          If you have suction piping, you must meet one of the following:
             monthly vapor monitoring
             monthly groundwater monitoring
                 If you are using groundwater or vapor monitoring for your tank, you may be
                 using these methods for your piping too.
             monthly SIR - check your monthly SIR reports to see if this method is also being
             used for your piping.
             monthly interstitial monitoring - to use this method, your piping must be
             secondarily contained and you must be monitoring the interstitial space at least
             once every 30 days for releases. If you have a hazardous substance LIST, you
             must either use interstitial monitoring or have a waiver from  {state}.
             line tightness test every three years - you must have a line tightness test
             conducted at least every three years for suction piping. See section 4.8.3 for
             information and checklists for line tightness testing.
          •   no release detection and you meet the criteria described in the box below.
 No release detection is required for suction piping that meets the following conditions:
    •   the piping is sloped so product will drain back to the tank when suction is lost, and
    •   there is only one check valve located as close as practical to the suction pump
        beneath the dispenser.
 Piping that meets these two criteria is sometimes called safe suction or European suction.
 Piping that does not meet these conditions is sometimes called U.S. suction or American
 suction.
          If you use monthly groundwater monitoring (section 4.7.3), vapor monitoring (section
          4.7.4), or SIR (section 4.7.8), the requirements are the same for both tanks and
          piping. Monitoring wells need to be placed appropriately to detect a release from all
          parts of the piping.

          If you use interstitial monitoring (section 4.7.2), the requirements are the same for both
          tanks and piping. In addition, if you use sump sensors, you must ensure the
          following for interstitial monitoring for piping:
              Interstitial monitoring sensors are typically located in a sump above the tank or
              the dispenser sump areas. These  sumps must be tight and free of leaks for
              piping interstitial monitoring to operate correctly.
              -  Piping should slope to the sump containing the monitoring sensor.
              -  Make sure the rubber boot is pulled back from the outer wall of the piping so
                 product will drain into the sump if a problem occurs.
              -  Make sure the sump does not have any water in it.
              -  Make sure the sensors are located near the bottom of the sump so they
                 activate quickly when a release occurs.
                                                                             Chapter 4

   Section 4.9: What To Do For Suspected Or Confirmed Releases
r           \   Personnel at your facility should be fully prepared to respond to releases
^	'   before they occur. In addition, employees need to know what to do when
              release detection methods indicate a suspected or confirmed release.

Requirements And Best Management Practices For Suspected Or Confirmed Releases

  ^
  I      You must respond to, investigate, and report suspected or confirmed releases when
         they occur.
         The following steps will assist you in responding to suspected or confirmed releases.
      Step 1. Stop The Release

      •   Take immediate action to prevent the release of more product.
      •   Turn off the power to the dispenser and tie a plastic bag around the nozzle.
         Make sure you know where your emergency shutoff switch is located.
         If necessary, empty the tank.  Be careful to avoid further contaminating the site. You
         may need the assistance of your supplier or distributor.

      Step 2. Contain The Release

      Contain, absorb, and clean up any surface release. You should keep enough absorbent
      material at your facility to contain a spill or overfill of petroleum products until emergency
      response personnel can respond to the incident.

      The suggested supplies include, but are not limited to, the following:

         Containment devices, such as containment booms, dikes, and pillows.
      •   Absorbent material, such as kitty litter, chopped corn cobs, sand, and sawdust.  Be
         sure you properly dispose of used absorbent materials.
         Mats or other material capable of keeping spill or overfill out of nearby storm drains.
         Spark-free flash light.
         Spark-free shovel.
         Buckets.
         Reels of caution tape, traffic cones, and warning signs.
         Personal protective gear.

      Step 3. Identify Any Hazards

      Identify any fire, explosion,  or vapor hazards and take action to neutralize these hazards.


                                                                         Chapter 4

-------
     Step 4.  Call For Help

     Contact your local fire or emergency response authority. Make sure you have these
     crucial telephone numbers prominently posted where you and your employees can
     easily see them.

     Step 5.  Report To Authorities

     If you observe any of the following, contact {state} to report a suspected or confirmed
     release as soon as possible (within 24 hours):
     •   Any spill or overfill of petroleum that exceeds 25 gallons or causes a sheen on
         nearby surface water. Spills and overfills under 25 gallons that are contained and
         immediately cleaned up do not have to be reported. If they cannot be quickly cleaned
         up, they must be reported to your regulatory authority.
     •   Any released product at the UST site or in the surrounding area — such as the
         presence of liquid petroleum; soil contamination; surface water or groundwater
         contamination; or petroleum vapors in sewer, basement, or utility lines.
     •   Any unusual operating conditions you observe — such as erratic behavior of the
         dispenser, a sudden loss of product, or an unexplained presence of water in the
         tank. However, you are not required to report if the system equipment is found to be
         defective, but not leaking, and is  immediately repaired or replaced.
         Results from your release detection system indicate a suspected release. However,
         you are not required to report this if:
         -  The monitoring device is found to be defective and is immediately repaired,
            recalibrated, or replaced and  further monitoring confirms the initial suspected
            release did not happen.
         -  In the case of inventory control, a second month of data does not confirm the
            initial result.

         Keep a list of emergency contacts and make sure everyone at your UST  facility is
         familiar with the  list of contacts.  Appendix D contains a blank list for names and
         phone numbers of important contacts. Fill out this information for your facility so
         you will know who to call  in case  of an emergency. Remove this page from the
         manual,  copy it,  fill it out,  and post it in a prominent place at your facility.
              Summary Of Compliance With Suspected Or Confirmed Releases
Answer the following question:
Yes
No

Requirements For Financial Responsibility Mechanisms

          You must have an appropriate FR mechanism at your facility.  The following mechanisms
          may be used to comply with the FR requirements. You may use one or a
          combination of these mechanisms.

•  Financial Test Of Self-Insurance - A firm with a tangible net worth of at least $10 million
   may demonstrate FR by passing one of the two financial tests listed in the federal
   regulations.
   Corporate Guarantee - You may secure a corporate guarantee from  another eligible firm.
   The provider of the guarantee has to pass one of the financial tests listed in the regulations.
   Insurance Coverage - You may buy insurance from an insurer or a risk retention group.
   Surety Bond - You may obtain a surety bond, which is a guarantee by a surety company
   that it will satisfy FR  obligations if the person who obtained the surety bond does not.
   Letter Of Credit - You may obtain a letter of credit, which obligates the issuer to provide
   funding for corrective action and third-party compensation.
   Trust Fund - You may set up a fully-funded trust fund administered by a third party to pay
   for corrective action and third-party compensation.
   Other State Authorized Methods - You may use additional methods of coverage (e.g.,
   certificate of deposit) authorized in {state}. Contact {state} to find out  if this can apply to you.
   State Financial Assurance Funds - You may be covered by a state  fund that provides all
   or a portion of FR to  the degree it pays for cleanup and third-party compensation costs.

If you are a local government, there are four additional methods that you can use to comply with
the FR requirements:

•  Bond Rating Test -  A local government may demonstrate (or guarantee) FR by passing a
   bond rating test.
   Financial Test - A local government may demonstrate (or guarantee) FR by passing a
   financial test.
   Guarantee - A local  government may obtain a guarantee from another local government or
   the state.
   Dedicated Fund - A local government may demonstrate (or guarantee)  FR by establishing a
   fund.

You may use one or a combination of mechanisms listed above to meet your FR obligations.
Combinations may be used to cover:

   Different sets of tanks - For example, tanks in one state may be covered by a state fund,
   while tanks in another state may be covered by insurance.
   Different scopes of coverage - For example, an owner may use a state fund to cover
   corrective action obligations and a letter of credit to cover third-party liability obligations.
   Different dollar amounts of coverage - For example, an owner may have a letter of credit
   for the first $20,000 (the deductible amount) of coverage and state fund coverage for the
   rest.
                                                                            Chapter 4

-------
Requirements For Financial Responsibility Amount Of Coverage
          Your FR mechanism (or combination of mechanisms) must provide the appropriate
          amount of coverage. The text and table below describe the appropriate coverage.

          The amount of coverage required varies by the type of tank owner or operator and
          the number of tanks owned or operated.  There are two general types of coverage
          required:  per occurrence and annual aggregate.

             Per occurrence means the amount of money that must be available to pay the
             costs for each occurrence of a leaking LIST. The amount of per occurrence
             coverage required depends on the type of facility and, in some cases,  on the
             amount of throughput at the facility.

          •   Annual aggregate means the total amount of FR available to cover all
             obligations that might occur in one year. The amount of annual aggregate
             coverage required depends on the number of tanks that are owned or operated.

          The amount of coverage required is provided in the table below.
                       Required Coverage Of Financial Responsibility
   Group Of LIST Owners And Operators

 Group 1:  Petroleum producers, refiners,
 or marketers

 Group 2:  Non-marketers (Non-marketing
 facilities do not sell or transfer petroleum to
 the public or any other facility that would sell
 the petroleum.  Additionally, non-marketing
 facilities do not produce or refine petroleum.
 An example of a non-marketer is a bus
 terminal.)
       $500,000

Requirements For Financial Responsibility Scope Of Coverage

  £•1    Your FR mechanism (or combination of mechanisms) must provide the appropriate
  I       scope of coverage.
          The scope of coverage your insurance must provide includes different types of
          obligations and releases.

             Types of Obligations - FR must cover the costs of corrective action and third-
             party compensation.  Third-party compensation includes bodily injury and
             property damage.

             Types of Releases - Owners or operators must demonstrate FR for taking
             corrective action and for compensating third parties for bodily injury and property
             damage caused by accidental releases. FR is not required for intentional
             releases. An accidental release may be sudden or non-sudden.  All releases,
             whether sudden or non-sudden, must be covered.  This is necessary to ensure
             adequate coverage for USTs in particular, because it is often difficult to
             determine whether an LIST release is sudden or gradual.  Therefore, to ensure
             adequate protection of human health and the environment, both types of
             coverage are necessary.
Requirements For Financial Responsibility Certification

          You must maintain an up-to-date certification of FR.

          The certification of FR must identify the financial assurance mechanism(s) used to
          demonstrate FR.  For each mechanism, the owner or operator must list the
          following:
          •   type of mechanism,
             name of issuer,
             mechanism number (if applicable),
             amount of coverage,
             effective period of coverage, and
          •   whether the mechanism covers taking corrective action and/or compensating
             third parties for bodily injury and property damage caused by either sudden
             accidental releases or non-sudden accidental releases or accidental releases.

          You must update this certification whenever the financial assurance mechanism(s)
          used to demonstrate financial responsibility change(s).
                                                                            Chapter 4
                                         116                             Section 4.10

-------
Requirements For Financial Responsibility Records And Reporting

          You must maintain the appropriate records.

             In addition to the certification of FR, you must keep evidence of all financial
             assurance mechanisms used.

          •   You must maintain the evidence of all financial assurance at the underground
             storage tank site or the place of work.  Records maintained off-site must be made
             available upon request of the implementing agency.

             In all cases, you must maintain a copy of documentation for your FR mechanism
             as worded in the regulations. Depending upon the mechanism used, various
             other documentation must be maintained as well.
          You must submit appropriate FR documentation to the implementing agency in the
          following circumstances:

          •   Within 30 days after you identify a release from an LIST.

             If you fail to obtain alternate coverage when required.

          •   At any time, as requested by the implementing agency. Many states require
             annual reporting of FR documentation.
                                                                           Chapter 4

             USTs in temporary closure must meet the requirements for corrosion protection
             and, if not emptied, the requirements for release detection.  USTs in temporary
             closure for more than three months must have their vent lines open and all other
             lines, pumps, manways, and ancillary equipment must be capped and secured.

           Directions For Completing The Temporarily Closed USTs Section
 Step 1:  Answer the question below.

 Step 2:  Proceed as instructed by the text in the grey box below the question.
 Do you have at least one LIST that is in temporary closure?   Yes   No  (Circle one)
 Typically, you as an owner or operator would have decided to place an LIST in temporary
 closure.  If you are not sure whether you have an LIST in temporary closure, contact {state}.
  If you answered yes to this question, read the requirements below and complete the
  Checklist For USTs In Temporary Closure questions and Summary Of Compliance For
  Temporary Closure question on the next page for each LIST in temporary closure.

  If you answered no to this question, skip section 4.11.
Requirements For Temporarily Closed USTs

          If your LIST is not empty, it must continue to meet the leak detection requirements for
          both tank and piping.
          •   An empty tank means that no more than one inch of residue (including product,
             sludge, water, etc.) or 0.3 percent by weight of the total tank capacity, remain in
             the LIST. Empty tanks do not require leak detection.

          All corrosion protection systems must remain operational on the LIST and must
          continue to be monitored. Vent lines should remain open.
         If an LIST remains temporarily closed for more than three months, you must leave
         vent lines open but close all other lines, pumps, manways, and ancillary equipment
         by capping and securing them.
         You must respond to any releases from your temporarily closed LIST, just as you
         would from an LIST that you are currently using.
                                                                          Chapter 4

Definitions Developed Or Gathered For This ERP Workbook And Not
Listed In The Federal Regulations

Coating means a layer of dielectric material (a material that does not conduct direct electrical
current) that is applied to the outside wall of steel tanks and piping.

Compliance means that a facility meets the minimum requirements as stated in the regulations.

Corrective Action means activities associated with cleaning up a site where a  release to the
environment has occurred.

Corrosion means the degradation of a material due to a reaction with its environment.  An
example of corrosion is the rusting of steel.

Empty means that all materials have been removed using commonly employed practices so
that no more than 2.5 centimeters (one inch) of residue (including product, water, sludge, etc.),
or 0.3 percent by weight of the total tank capacity of the LIST system, remain in the system.

Field Constructed  Tank is a tank that was not constructed or built in a factory, but rather,
constructed or built  in the field (such as at the  location where it was installed). For example,
very large tanks may be field constructed.

Fill  Pipe is the pipe that extends from the surface to the tank that is used for filling the tank with
substances.

Financial Responsibility is the ability to pay for cleanup  or third-party liability compensation.

Non-corrodible material means a material that will not corrode or degrade  in the environment
where it is placed.  For example, fiberglass material in the soil.

Non-marketing facility  means a facility that does not sell or transfer petroleum to the public or
any other facility that would sell the  petroleum. Additionally, non-marketing facilities do not
produce or refine petroleum.  An example of a non-marketer is a bus terminal.

Pressurized Delivery is a delivery where product is pumped from the delivery truck to the tank.

Secondary Containment is an additional barrier between the part of the tank or piping that
contains product and the outside environment. Examples of secondary containment are double-
walled tanks and piping, tank bladders, tank jackets, and excavation liners.
                                                                          Appendix E

-------
Stage I Vapor Recovery is a system that captures the vapors expelled from an underground
storage tank as a result of being filled by a delivery truck. There are two primary types - coaxial
and two point. Coaxial Stage I  vapor recovery is two concentric channels, one inside of the
other. The inner channel conveys product from the delivery truck to the tank while the outer
channel conveys vapors from the tank to the delivery truck.  Two point Stage I vapor recovery
uses two separate connections, one to deliver product to the tank and the other to deliver
vapors to the delivery truck.

Sump means an underground area such as a hole or pit that is used to house equipment.
Sumps may or not be contained.

(a)    in the case of a turbine sump, it is an area above the  tank over which a cover is placed
      that houses the submersible turbine pump head, line  leak detector, piping and other
      equipment.

(b)    In the case of a dispenser sump, it is the area  beneath a dispenser that houses piping
      and other equipment.

     Appendix G: Examples Of Placards For Overfill Devices
    Delivery Person -  Avoid Overfills

An overfill alarm is used for overfill protection at this
facility.

Do not tamper with this alarm in any attempt to defeat
its purpose.

When the tank is 90 percent full or is within one minute
of being overfilled, the overfill alarm sounds and/or a
light comes on or flashes.

If you hear the alarm or see the light on or flashing,

Stop The Delivery Immediately!

    Delivery Person - Avoid Overfills

A ball float valve is used for overfill protection at this
facility.

Do not tamper with this device in any attempt to defeat
its purpose.

When the tank is 90 percent full, or 30 minutes prior to
when the product would overfill the tank, the ball float
will activate and the flow rate of the delivery will
decrease noticeably.

When you notice a decrease in flow rate,

Stop The Delivery Immediately!

An automatic shutoff device is used for overfill
protection at this facility.

Do not tamper with this device in any attempt to defeat
its purpose.

When the tank is 95 percent full or before the fittings on
top of the tank are exposed to product, the device will
activate and slow down, and then stop the delivery
before the tank is overfilled.

When the automatic shutoff device activates,

Stop The  Delivery Immediately!

Site Sketch: Provide a rough sketch of the tanks and piping, the location of each CP test, and
each voltage value obtained (use space below or attach separate drawing). Voltage readings
through concrete or asphalt do not provide accurate readings and are not acceptable. Perform
sufficient testing to evaluate everything that is cathodically protected.
 If the cathodic protection system fails the test, a corrosion expert must evaluate the
 cathodic protection system so it can be fixed.  A corrosion expert has additional training,
 skills, and certification beyond the corrosion tester who filled out the bulk of this form. A
 corrosion expert must be: accredited/certified by NACE International, The Corrosion Society
 as a corrosion specialist or cathodic protection specialist or be a registered professional
 engineer with certification or licensing in corrosion control.

  Be sure to keep a record for as long as you own the LIST that clearly documents what
                       actions were taken to fix your CP system.

OWNER WAS CONTACTED TO CLARIFY RESPONSES, COMMENTS:
INSTRUCTIONS AND GENERAL INFORMATION ^^^^^^^^^^^^^^^^^^^^^^^^^^^^|
Please type or print in ink. Also, be sure you have signatures in ink for
sections VIII and XI. Complete a notification form for each location
containing underground storage tanks. If more than 5 tanks are owned at
this location, you may photocopy pages 3 through 5 and use them for
additional tanks.
The primary purpose of this notification program is to locate and evaluate
underground storage tank systems (USTs) that store or have stored
petroleum or hazardous substances. The information you provide will be
based on reasonably available records, or in the absence of such records,
your knowledge or recollection.
Federal law requires UST owners to use this notification form for all
USTs storing regulated substances that are brought into use after May
8, 1986, or USTs in the ground as of May 8, 1986 that have stored
regulated substances at anytime since January 1, 1974. The
information requested is required by Section 9002 of the Resource
Conservation and Recovery Act (RCRA), as amended.
Who Must Notify? Section 9002 of RCRA, as amended, requires owners of
USTs that store regulated substances (unless exempted) to notify
designated State or local agencies of the existence of their USTs. "Owner" is
defined as:
• In the case of an UST in use on Novembers, 1984, or brought into use
after that date, any person who owns an UST used for storage, use, or
dispensing of regulated substances; or
• In the case of an UST in use before November 8, 1 984, but no longer in
use on that date, any person who owned the UST immediately before its
discontinuation.
Also, if the State so requires, any facility that has made any changes to
facility information or UST system status, must submit a notification form
(only amended information needs to be included).
What USTs Are Included? An UST system is defined as any one or
combination of tanks that (1 ) is used to contain an accumulation of regulated
substances, and (2) whose volume (including connected underground
piping) is 10% or more beneath the ground. Regulated USTs store
petroleum or hazardous substances (see the following "What Substances
Are Covered").
What Tanks Are Excluded From Notification?
•• Tanks removed from the ground before May 8, 1986;
• Farm or residential tanks of 1 ,1 00 gallons or less capacity storing motor fuel
for noncommercial purposes;
• Tanks storing heating oil for use on the premises where stored;
• Septic tanks;
• Pipeline facilities (including gathering lines) regulated under the Natural Gas
Pipeline Safety Act of 1 968, or the Hazardous Liquid Pipeline Safety Act of
1979, or which is an intrastate pipeline facility regulated under State laws;
• Surface impoundments, pits, ponds, or lagoons;
• Storm water or waste water collection systems;
• Flow-through process tanks;
• Liquid traps or associated gathering lines directly related to oil or gas
production and gathering operations;
• Tanks on or above the floor of underground areas, such as basements or
tunnels;
• Tanks with a capacity of 1 1 0 gallons or less.
What Substances Are Covered? The notification requirements apply to USTs
containing petroleum or certain hazardous substances. Petroleum includes
gasoline, used oil, diesel fuel, crude oil or any fraction thereof which is liquid at
standard conditions of temperature and pressure (60 degrees Fahrenheit and
1 4.7 pounds per square inch absolute). Hazardous substances are those found
in Section 101 (14) of the Comprehensive Environmental Response,
Compensation and Liability Act of 1 980 (CERCLA), with the exception of those
substances regulated as hazardous waste under Subtitle C of RCRA.
Where To Notify? Send completed forms to:
