1. Where is your oil tank located: · if it applies
I have a below-ground heating oil tank · I have an above-ground heating oil tank
If you have an above-ground oil tank, please describe where it is located: · if it applies
Please initial one of the four options listed below: · if it applies
1. Option 1: I agree to let the Oﬃce of Housing decommission (remove or clean and ﬁll) my underground heating oil tank by leaving it in place. They will hire a furnace company to remove the oil and ﬁll the tank with a material like sand or foam, making it unusable. By choosing this, I won’t be covered by PLIA for any leaks. I also understand that my oil tank system may have leaked before. If there was a leak in the past, I might be responsible for cleanup costs, impacting my property value. The City won’t do any tests to check for past oil leaks. Finally, I understand that if I have Pollution Liability Insurance under PLIA, it will end 30 days after disconnecting the tank from the furnace, leaving me without coverage if an old leak is found later. · 2. Option 2: I have an above-ground oil tank and to take part in this program, I need to choose to have it taken away from my property. I know that I have 30 days from the day the tank is disconnected from the furnace to ﬁle a claim with PLIA if there is contamination from an oil leak. I understand that the City of Seattle is not connected with PLIA and that I am responsible for any communications and negotiations with PLIA. If there is an oil leak found during the removal of my oil tank, the City of Seattle will not be responsible for any contamination clean-up or related costs. I also understand that any coverage exclusions, policy coverage limits, or liability under my PLIA policy are not the City of Seattle’s responsibility. · 3. Option 3: I choose to remove my below-ground heating oil tank and I have PLIA insurance. I understand I need to hire a furnace contractor to take out my oil tank, and I am responsible for the removal cost. I know that I have 30 days after the tank is disconnected to tell PLIA if there’s contamination from an oil leak. The City of Seattle is not connected to PLIA, and I am responsible for any communications and negotiations with PLIA. If there is an oil leak during the removal, the City of Seattle won’t cover cleanup costs, or anything related. Any issues with my PLIA policy, like coverage limits or exclusions, are my responsibility, not the City’s. · 4. Option 4: I choose to have my below-ground heating oil tank removed, and I am not insured by PLIA. I understand I need to hire a furnace contractor/service provider to take out my oil tank, and I am responsible for the removal cost. If there is an oil leak during the removal, the City of Seattle won’t cover cleanup costs, or anything related.

What you agree to

By signing below, I certify that the information provided in this application and the required documentation is complete and accurate. I understand that I may be subject to criminal prosecution if I have knowingly provided false information. I give the City of Seattle permission to request or release information to other non-profit or government organizations to assist me. This information may include but is not limited to, my application including income and related documentation, photographs showing the before and after condition of my home, and Weatherization’s scope of work. Such information may result in my receiving or being denied other City assistance.

For state weatherization programs: I understand that I may request a Fair Hearing if the information I have provided above is not acted on to determine my eligibility within a reasonable time or if I do not receive benefits for which I am eligible. I give the City permission to enroll me in all City or King County assistance programs for which I am eligible.

The information you provide will be used for the purpose of reviewing your application. The City of Seattle may share the information you provide with City of Seattle departments for the purpose of providing you with information on additional programs for which you may be eligible. If you provide consent to enroll in an additional program for which you are eligible, the City of Seattle may also share the information with City of Seattle departments to enroll you in the additional program. We will not knowingly share your information for enforcement purposes of any kind or for any other reason unless compelled by law. To learn more, please see the Public Records Act (RCW Chapter 42.56). The City of Seattle Privacy Statement explains how we handle the information you give us.

The utility company(s) may release past and future use information on my household to the City of Seattle’s Office of Housing (OH) HomeWise Weatherization Program. If I am eligible for service, I permit OH, its staff, and contractors to gain access to this property for audit, installation, and inspection purposes. In the case that work requires later inspection from Seattle City Light or the State of Washington, I agree to provide access for these audit purposes.

Section 2: Program Agreements I understand that my participation in the Oil-to-Electric Program complies with the following agreement: 1. I understand that the City of Seattle will decommission my below-ground heating oil tank, by filling it in place in accordance with Section 5704.2.13 of the Seattle Fire Code: https://www.seattle.gov/Documents/Departments/Fire/Business/5962CAMDecommisionOilTanks 2. Release and Indemnification: I promise not to hold the City of Seattle, Office of Housing, and/or its agents, officials, and employees responsible for any harm, injuries, or damage that might happen during the work at the home address mentioned. This includes any issues related to the work or any unexpected events that might arise from it. I agree to protect and defend the City and its representatives from any claims or liabilities in connection with the work. This promise is crucial for the City’s decision to hire someone to decommission the tank at the specified address. I acknowledge that the City will cover the costs of the contract and permits for the tank decommissioning; however, the City is not guaranteeing the contractor’s performance, and the City is not accountable for any actions or mistakes made by the contractor during the work. 3. I understand that the city will not go on with the decommissioning of my heating oil tank if there is any evidence of a prior or active oil leak. If that is the case, then my Oil-to-Electric conversion will be put on hold unless I decide that I will have my tank removed along with any contaminated soil. I understand that I will need to handle the tank removal and cover any expenses to fix the contaminated soil. If I am insured, I understand the removal of contaminated soil may be addressed by my PLIA insurance. If I do not have PLIA insurance, and I decide to remove my oil tank, I understand those costs will be my sole responsibility. Grants and loans may be available through the PLIA Loan and Grant program with more information at: www.plia.wa.gov. This is a program administered by the WA State Pollution Liability Insurance Agency and not the City of Seattle.

1. Option 1: I agree to let the Oﬃce of Housing decommission (remove or clean and ﬁll) my underground heating oil tank by leaving it in place. They will hire a furnace company to remove the oil and ﬁll the tank with a material like sand or foam, making it unusable. By choosing this, I won’t be covered by PLIA for any leaks. I also understand that my oil tank system may have leaked before. If there was a leak in the past, I might be responsible for cleanup costs, impacting my property value. The City won’t do any tests to check for past oil leaks. Finally, I understand that if I have Pollution Liability Insurance under PLIA, it will end 30 days after disconnecting the tank from the furnace, leaving me without coverage if an old leak is found later.

2. Option 2: I have an above-ground oil tank and to take part in this program, I need to choose to have it taken away from my property. I know that I have 30 days from the day the tank is disconnected from the furnace to ﬁle a claim with PLIA if there is contamination from an oil leak. I understand that the City of Seattle is not connected with PLIA and that I am responsible for any communications and negotiations with PLIA. If there is an oil leak found during the removal of my oil tank, the City of Seattle will not be responsible for any contamination clean-up or related costs. I also understand that any coverage exclusions, policy coverage limits, or liability under my PLIA policy are not the City of Seattle’s responsibility.

3. Option 3: I choose to remove my below-ground heating oil tank and I have PLIA insurance. I understand I need to hire a furnace contractor to take out my oil tank, and I am responsible for the removal cost. I know that I have 30 days after the tank is disconnected to tell PLIA if there’s contamination from an oil leak. The City of Seattle is not connected to PLIA, and I am responsible for any communications and negotiations with PLIA. If there is an oil leak during the removal, the City of Seattle won’t cover cleanup costs, or anything related. Any issues with my PLIA policy, like coverage limits or exclusions, are my responsibility, not the City’s.

4. Option 4: I choose to have my below-ground heating oil tank removed, and I am not insured by PLIA. I understand I need to hire a furnace contractor/service provider to take out my oil tank, and I am responsible for the removal cost. If there is an oil leak during the removal, the City of Seattle won’t cover cleanup costs, or anything related.

By signing below, I understand the Agreement, and as the legal owner(s) of the property, have initialed the corresponding paragraph with my decision regarding the heating oil tank. If the property is owned by multiple owners, each owner needs to sign below and attach an additional page if necessary.

5. I certify that the information I have provided above is complete and accurate to the best of my knowledge. I understand that I am signing this statement under penalty of prosecution if I knowingly give false information, which results in assistance received for which I am not eligible.

I certify that I know of and have satisfactory evidence that is the person who appeared before me, and said person acknowledged that they signed this document and acknowledged it to be their free and voluntary act for the uses and purposes mentioned in this document.
