New York State has one of the highest concentrations of aging residential oil tanks in the country — particularly on Long Island and in older Upstate cities. Underground storage tanks are governed by 6 NYCRR Part 613 under the NYSDEC. All contractors performing UST removals must be NYSDEC-registered petroleum contractors.
Costs vary dramatically by region: Upstate NY averages $1,500–$2,800 for a clean underground removal. Westchester and Hudson Valley run $2,000–$3,500. Long Island averages $2,500–$4,500 due to Nassau and Suffolk county permit requirements and groundwater sensitivity. NYC five boroughs can reach $3,000–$6,000, with FDNY permits adding cost and processing time.
New York's Property Condition Disclosure Act requires sellers to disclose known environmental conditions including underground storage tanks. Buyers should always request full tank closure documentation including NYSDEC closure letter and soil test results. Long Island lenders routinely require proof of clean closure before underwriting.
New York's Spill Fund provides cleanup assistance for qualifying releases. Report petroleum spills immediately to the NYSDEC Spill Hotline at 1-800-457-7362.
