Information

Referral History:

On March 24, 2019, the Public Works Department – Airports Division (Airports) received a letter from the San Francisco Bay Regional Water Quality Control Board, relative to Order WQ 2019-0005-DWQ (Order), for determination of the presence of PFAS substances at Buchanan Field Airport (Buchanan Field). PFAS substances have been used in the production of many products (such as dental floss, water repellent clothes and goods, and textiles). PFAS exposure through drinking water has become an increasing concern due to the tendency of PFAS to accumulate in groundwater.

Buchanan Field was identified as a facility that has accepted, stored, or used materials that may contain PFAS substances. Aqueous Film-Forming Foams (AFFF) foam used for Aircraft Rescue and Firefighting (ARFF), as required by the Federal Aviation Administration for commercial airports, contains PFAS substances.

The Airports must prepare a response to the State Water Resources Control Board related to determining the presence or absence of PFAS substances at Buchanan Field Airport. The response includes completion of a questionnaire that was included in the Order to determine whether PFAS compounds have been used or stored at Buchanan Field and, if so, identify locations where they were used or stored. To comply with the Order, a preliminary soil and groundwater investigation work plan must be developed and submitted within sixty days from receipt of the letter. Subsequent actions, not included in the current work scope and cost, will include implementing the field investigation identified in the work plan and preparation of a final sampling and analysis report.

Referral Update:

None.

Recommendation(s)/Next Step(s):

Discuss the PFAS Order and response requirements relative to Buchanan Field Airport.

Fiscal Impact (if any):

The cost to prepare a response to the Order, including a completed questionnaire and work plan, is $67,302 which will be paid from the Airport Enterprise Fund.
