RECOMMENDATION(S):

APPROVE and AUTHORIZE the Director of Airports, or designee, to execute a contract amendment with Mead & Hunt, Inc. to extend the term from June 30, 2021 to September 30, 2021 with no increase to the payment limit. (District IV)

FISCAL IMPACT:

There is no impact on the General Fund. Costs incurred under the contract are paid by the Airport Enterprise Fund and the payment limit on the contract has not increased.

BACKGROUND:

In March 2019, the California State Water Resources Control Board (State Water Board) issued Order WQ 2019-0005-DWQ (Order), which requires certain airports, including Buchanan Field Airport, to

BACKGROUND: (CONT'D)

(i) conduct a “one-time preliminary site investigation” regarding the storage and use of Per- and Polyfluoroalkyl Substances (PFAS), and (ii) obtain a preliminary understanding of PFAS concentrations in soil and/or groundwater resulting from the use of PFAS at the airport. PFAS is a family of more than 3,000 man-made and mostly unregulated chemicals that are resistant to degradation in the environment. PFAS are manufactured globally and have been used in the production of many industrial and household products such as dental floss, non-stick cookware and products, waterproof products, cleaning products, and fire-fighting foams. The Order applies to Buchanan Field because Buchanan Field operates pursuant to 14 CFR Part 139. As a result of the Order, the County was required to submit an investigation work plan and final report to the local Regional Water Quality Control Board (Regional Water Board).

The County engaged Mead and Hunt to prepare the required work plan and final report through a contract dated August 1, 2019. The contract has already been amended once to extend its terms and increase the payment limit in order to permit Mead and Hunt to perform additional work that was required by the Regional Water Board following its review of the preliminary work plan. Mead and Hunt completed all the work initially required by the Regional Water Board prior to the deadline. The Regional Water Board formally accepted the required work plan on December 19, 2019.

The Regional Water Board is now requesting a new work plan more focused on the lateral and vertical extent of PFAS found on the Airport during previous soil and groundwater sampling. Because the contract with Mead and Hunt was to expire on June 30, 2021, and more time is needed to complete the work required by this new request from the Regional Water Board, the contract was extended for an additional three months with no increase in the payment limit. The purpose of this board order is to obtain approval of the contract extension.

CONSEQUENCE OF NEGATIVE ACTION:

Failure to complete the work being done by Mead and Hunt under this contract would expose the County to a potential daily fine (up to $5,000) and criminal penalties.
