RECOMMENDATION:
Approve and authorize the Purchasing and Contracts Manager to enter into a one (1) year Sole Source Service Contract with The Regents of the University of California on behalf of its San Diego campus' Scripps Institution of Oceanography, for a total amount not to exceed $40,000, with two (2) optional one (1) year renewals at $40,000 per renewal, for a total amount not to exceed $120,000 for the three-year period, to develop best practices and analyze seawater for pH in compliance with permit mandated data quality requirements and regional comparability as recommended by the Bight'13 Nutrients Study.

BACKGROUND
The Orange County Sanitation District (Sanitation District) is required to measure acidity/alkalinity (i.e., pH) in order to comply with the California Ocean Plan (COP). However, commercially available pH sensors for oceanographic instrumentation (CTD - conductivity, temperature, depth) are not currently capable of achieving the required data quality. Thus, the Sanitation District participated in the Bight'13 Nutrients Study to explore improvements for oxygen, pH, and transmissivity sensors that would provide consistency across all ocean discharges and increase sensor stability and precision. The Bight'13 Nutrients Study recommended a follow-up project for Bight'18 to develop best practices for pH measurements and enhance data quality.
RELEVANT STANDARDS
* Comply with environmental permit requirements
* Listen to and seriously consider community input on environmental concerns
* Build brand, trust, and support with policy makers and community leaders
PROBLEM
The Sanitation District's ocean discharge permit mandates that we meet compliance standards with physi...
