Structure of the Low-Threat Closure Policy

In order to qualify for low-threat UST case closure using this Policy:

• A site must satisfy all of the General Criteria, and

• A site must also satisfy the Media-Specific Criteria for

Groundwater, Vapor Intrusion to Indoor Air, and Direct Contact

and Outdoor Air Exposure by either:

– Meeting the ‘Tier One Criteria’

(Classes, Scenarios/Appendix 1-4, Table 1); or

– A Site-Specific Assessment/Analysis; or

– Controlling Exposure; or

– Qualifying for an Exception

• Notification Requirements, Monitoring Well Destruction

Requirement, and Waste Removal Requirement

LTCP General Criteria

General criteria that must be satisfied by all candidate sites:

1. The unauthorized release is located within the service area of public

water system;

2. The unauthorized release consists only of petroleum;

3. The unauthorized (“primary”) release from the UST system has been

stopped;

4. Free product has been removed to the maximum extent practicable;

5. A conceptual site model that assesses the nature, extent, and

mobility of the release has been developed;

6. Secondary source has been removed to the extent practicable;

7. Soil or groundwater has been tested for MTBE and results reported

in accordance with Health and Safety Code Section 25296.15;

8. Nuisance as defined by Water Code section 13050 does not exist at

the site.

LTCP Implementation

• LTCP has been in effect for 1 year (August 2012)

• Each agency reviewed all of their cases to determine if

the LTCP closure criteria were met

• 1400 cases (25%) met the LTCP Criteria with existing data

• Roughly 50% of cases seem to be stuck in the regulatory

process

– No RP, no funding, etc.

• A path to closure will be developed for each case

Summary

• The UST cleanup program, as we know it, will be winding down over the next few years

• The likely sunset of our cleanup fund means that the remaining UST cleanup cases will be more dependent on the federal grant than in previous years

• We need to work on stuck cases to prevent a legacy of brownfield sites

• Other water quality issues are more pressing than petroleum
