Soil Cleanup

Site Remediation

If petroleum contamination is discovered, cleanup of the petroleum contamination may be needed, depending on the severity. Filco Environmental Tank Services uses several methods to clean up petroleum contaminated soil including digging the material out and replacing it with clean material. Another method is bioremediation, where we will inject the ground with oil-eating microbes which can be effective over a period of time in some soil conditions. When it comes to soil sampling, soil testing, or remediation, Filco Environmental Tank Services is the finest professional company in your community that provides the latest technology in serving your environmental needs for evaluation and site remediation.

The Heating Oil Loan and Grant (HOLG) Program

The Heating Oil Loan and Grant (HOLG) Program is run by the Washington State Pollution Liability Insurance Agency (PLIA). It helps owners of heating oil tanks with money to assess, clean up, and upgrade or replace heating oil systems, especially if there’s a leak or risk of future leaks. This program is taking the place of the former PLIA Insurance program. For more information, please visit the PLIA HOLG website: https://plia.wa.gov/heating-oil-loan-and-grant-program/

Heating Oil Pollution Liability Insurance Program (HOIP)

Heating Oil Pollution Liability Insurance Program (HOIP) — Past Coverage
Until recently, PLIA offered a no-cost pollution liability insurance policy that:

Provided up to $60,000 in coverage per claim for cleanup costs not covered by other insurance if an active, registered heating oil tank leaked.
Covered cleanup on your property and nearby neighboring property if contamination occurred.
Required registration of your tank before a leak occurred to qualify.
Was funded by fees paid by heating oil dealers.
Important changes as of 2025:
✔ The insurance policy expired on June 30, 2025 and PLIA stopped accepting new registrations and new claims after July 31, 2025.
✔ If you had a claim filed for a leak reported before July 1, 2025, PLIA will continue to administer it (i.e., they’ll process existing claims until closed or funds are used up)
