Cleanup Rules for Leaking Petroleum UST Systems: Numeric Soil Cleanup Standards

(1)

If the Matrix Score evaluated in OAR 340-122-0330 (Cleanup Rules for Leaking Petroleum UST Systems: Evaluation Parameters) is:

(a)

Greater than 40, the site must be cleaned up to at least the Level 1 standards listed in section (2) of this rule;

(b)

From 25 to 40, inclusive, the site must be cleaned up to at least the Level 2 standards listed in section (2) of this rule;

(c)

Less than 25, the site must be cleaned up to at least the Level 3 standards listed in section (2) of this rule.

(2)

The following table contains the required numeric soil cleanup standards based on the level of Total Petroleum Hydrocarbons (TPH) as measured by the analytical methods specified in OAR 340-122-0218 (Cleanup Rules for Leaking Petroleum UST Systems: Sampling and Analysis). [View a PDF of the table by clicking on the “Tables” link below.]

(3)

A sample of contaminated soil must be collected from each separate release area and used to identify the petroleum product contamination present at that location. The Hydrocarbon Identification test specified in OAR 340-122-0218 (Cleanup Rules for Leaking Petroleum UST Systems: Sampling and Analysis)(1)(c) (NWTPH-HCID) must be used for that purpose. The NWTPH-HCID test is not required for petroleum product identification for releases from residential heating oil tanks. The results of the NWTPH-HCID test must be used to determine which analytical method or methods are required for verifying compliance with the Matrix cleanup levels. At locations where the soil is contaminated with both gasoline and diesel or other non-gasoline fraction hydrocarbons, the gasoline contamination must be shown to meet the appropriate gasoline cleanup standard and the diesel or other non-gasoline fraction contamination must be shown to meet the appropriate diesel cleanup standard.
