A Century of Growth…From the “Lean and Many”, to the “Few and Fat”
![Page 10: USTLUST 050315 [Read-Only] - NEIWPCC€¦ · Title: Microsoft PowerPoint - USTLUST_050315 [Read-Only] Author: anyone Created Date: 3/24/2005 4:25:02 PM](https://reader033.vdocument.in/reader033/viewer/2022060100/60b1877b81f7bc37df03060d/html5/thumbnails/10.jpg)

What we knew then…Gas stations have a 100 year history;
Until the mid-80’s, agency records for underground storage tanks were inconsistent;
Site identification and cleanup is largely market or release driven;
Underground storage tanks have a limited lifespan; and,
Somewhere between 50–75% of older USTs have leaked.
![Page 11: USTLUST 050315 [Read-Only] - NEIWPCC€¦ · Title: Microsoft PowerPoint - USTLUST_050315 [Read-Only] Author: anyone Created Date: 3/24/2005 4:25:02 PM](https://reader033.vdocument.in/reader033/viewer/2022060100/60b1877b81f7bc37df03060d/html5/thumbnails/11.jpg)

Abandoned Commercial Tank Project (Project ACT)
GOALS AND OBJECTIVESPrevention: Assess risk and eliminate contaminant source before release occurs;Inventory all former gas station sites and determine compliance history;Develop inventory model for neighborhood Brownfields;Engage stakeholders early
Started in 2003;
Funded by a $230,000 Site Hazard Assessment Grant from WA Dept. of Ecology.
![Page 12: USTLUST 050315 [Read-Only] - NEIWPCC€¦ · Title: Microsoft PowerPoint - USTLUST_050315 [Read-Only] Author: anyone Created Date: 3/24/2005 4:25:02 PM](https://reader033.vdocument.in/reader033/viewer/2022060100/60b1877b81f7bc37df03060d/html5/thumbnails/12.jpg)

Stakeholder InvolvementGoals:
Identify and engage stakeholders earlyIdentify opportunities and potential roadblocksCommunicate department objectives
Objectives:
Meet with state and local agency staff (EPA, Ecology, Planning and Fire agencies)
Convened a series of focus groups:Environmental Professionals (environmental issues and opportunities)Agency Staff (regulatory issues and opportunities)Property Owners (ownership and economic issues and opportunities)

What we learned from property owners:
Reduce the unknowns:Environmental: Identify and communicate risks Government: Understand agency interests, enforcement threshold, and resources for technical assistanceFinancial: Identify resources for assessment, cleanup, and redevelopment
Streamlined permitting will enhance compliance and reduce frustrationGiven a choice, owners want to know about property history

What we’re planning next…(January – June 2005)Prioritize sites:
1. Work with local economic development and health department prevention priority staff to identify sites where environmental sensitivity, environmental justice, and redevelopment potential overlap;
2. Identify public sites eligible for assessment and/or cleanup grants;
3. Identify sites with high environmental priority (evidence of tank presence, station longevity, location in a wellhead protection zone, etc).

29
What we’re planning next…(Longer Term)
Help coordinate technical and financial assistance to property owners – all sites are different;Continue to assess public health role in promoting neighborhood Brownfields redevelopment;Evaluate inventory methodology and apply to other historic business types; andImplement Pilot Neighborhood Brownfields Program.

A Brownfields Primer…
Brownfields recently redefined to include petroleum sites;Grants and loans available to public agencies for inventory, assessment and cleanup;Low interest loans available to (non-liable) private parties for assessment and cleanup; andLeverages environmental public health goals by promoting cleanup and economic development together
