BACKGROUND/INFORMATION/SCHEDULE OF EVENTS

South Coast AQMD is a regional governmental agency responsible for meeting air quality health

standards in Orange County and parts of Los Angeles, Riverside and San Bernardino counties and

the Coachella Valley portion of the Salton Sea Air Basin.

South Coast AQMD has the need to procure compressed EPA protocol calibration gases, pure

gases, other specialty gases, and cryogenic liquids used in the sampling and analysis of ambient

air pollutants. The data from these analyses are required to satisfy Federal Air Monitoring program

requirements and are reported to the US EPA. South Coast AQMD also uses EPA protocol

calibration gases, ultrapure air, pure gases, and specialty gases in the sampling and analysis of

ambient air pollutants for AB617, special monitoring, laboratory operations, R1180, AQ-SPEC and

quality assurance purposes. The cost for these compressed gases and associated demurrage

costs are to be included in the quotation. The funds for the purchase of these gases are funded in

part by the U.S. EPA.

SECTION IV:

EVALUATION AND SELECTION CRITERIA

Award will be made to the vendor submitting the lowest cost quotation which is fully

responsive to the specifications set forth in the RFQ, and/or providing the best value to

the South Coast AQMD in accordance with the South Coast AQMD Procurement Policy

and Procedure.

Vendors that have a specialty gas point of contact, such as a specialty gas manager

and sales representative, will be given extra consideration during the selection

process. Indication of this on the quote is very important.

It is the policy of the South Coast AQMD to receive at least as favorable pricing, warranties,

conditions, benefits and terms as other customers or clients making similar purchases or receiving

similar services. To this purpose, formal bidding procedures, sole source awards, and RFP/RFQ

processes will include a certification for “most favored customer” status. South Coast AQMD will

give preference, where appropriate, to vendors who certify that they will provide “most favored

customer” status to the South Coast AQMD.

Quotes will be evaluated by a panel of three to five South Coast AQMD staff members familiar with

the subject matter including gas quality requirements and past South Coast AQMD supply, billing,

and general customer service histories with vendors. The panel shall be appointed by the

Executive Officer or his designee. In addition, the evaluation panel may include such outside public

sector or academic community expertise as deemed desirable by the Executive Officer. The panel

will make a recommendation to the Executive Officer and/or the Governing Board of the South

Coast AQMD for final selection of contractors and negotiation of contracts.

Each member of the evaluation panel shall be accorded equal weight in his or her rating of

proposals. The evaluation panel members shall evaluate the quotes according to the specified

criteria and numerical weightings set forth below.
