PROJECT:

Analysis of DNPH Aldehyde Cartridges and Non-

Methane Organic Compounds

PROPOSALS DUE BY: 5:00 PM on Friday, February 13, 2026

OVERVIEW

The San Joaquin Valley Unified Air Pollution Control District (District) collects ambient

air samples that can be analyzed for specific aldehyde compounds and specific Non-

Methane Organic Compounds (NMOC). Air samples are collected during the period of

June-August 2026, and sent a laboratory that will analyze and upload to EPA’s Air

Quality System (AQS) using AIRS parameter codes.

The District is issuing this Request for Proposal (RFP) to solicit laboratories for

analyzing air samples for acetaldehyde, acetone, and formaldehyde using

dinitrophenylhydrazene (DNPH) loaded cartridges as well as EPA’s list of PAMS

Compounds (Attachment C) as the targeted species for analysis of NMOC’s. For

appropriate DNPH samples laboratories must operate using test method TO-11 or TO-

15. Additionally, all analyses for NMOC’s be performed in adherence to the 1998 EPA

PAMS Technical Assistance Document (TAD), EPA method TO-15, or other methods

as appropriate for PAMS analysis in accordance with US EPA’s AQS database

requirements.

To be considered for this project, contractors must meet the minimum eligibility

requirements and submit a cost-effective proposal that satisfies the Proposal

Requirements in this RFP. For the analysis of DNPH cartridges, the District will pay on

a per cartridge basis. For NMOC analysis, the District will pay on a per canister basis.

Payments will be made subsequent to proper verification of completed monthly data

submission to EPA’s AQS database and District evaluation of EPA Quality Control

Reports, confirming that the work was completely and satisfactorily carried out.

Because District funding for the project may include federal funds:

 The contractor shall comply with all federal and state laws, statutes, and

regulations, which apply to performance of this Agreement and shall be

applicable to all parties, beneficiaries and any officer, agent, or employee of all

parties under this Agreement

 The contractor shall comply with all federal and state conflict of interest laws,

statutes, and regulations, which shall be applicable to all parties, beneficiaries

and any officer, agent, or employee of all parties under this Agreement.

 The contractor must not be presently debarred, suspended, proposed for

debarment, declared ineligible, voluntarily excluded from participation or

regarding entities debarred, suspended, proposed for debarment, excluded, or

otherwise declared ineligible from receiving Federal contracts. Access to the

EPLS is available at www.sam.gov.

 The contractor certifies by signing the signature page of the original copy of the

submitted proposal and any amendment signature page(s) that the proposer is

The contractor will provide certification that commercial general liability insurance

coverage ($1,000,000 per occurrence) for bodily or personal injuries or for property

damage as well as Workers Compensation Insurance as in accordance with the

California Labor Code are obtained and are in full force.

The District reserves the right to reject any and all proposals, and to make no awards.

DNPH Analysis:

1. At any time the District may require that the contractor successfully complete an

analysis of an Audit Sample or Performance Evaluation in order for the District to

evaluate the performance of the lab.

2. The contractor will supply the cartridges necessary for any Audit Sample or

Performance Evaluation.

3. In 2026, there will be approximately 350 samples sent to the contractor for

analysis. This number may increase or decrease depending on the number of

samples collected. Sampling is scheduled for June, July and August of 2026.

4. The contractor shall perform DNPH aldehyde cartridge analyses using TO-11 or

TO-15.

5. The three compounds to be analyzed are acetaldehyde, acetone, and

formaldehyde.

6. The contractor will supply new cartridges with DNPH loaded on a silica gel

substrate. The contractor will ship 350 cartridges to the District as soon as

possible after signing of the contract. The contractor will contact and coordinate

with the District with regards to shipping locations and addresses (Fresno and

Bakersfield). The contractor is responsible for all record keeping and costs

regarding shipping and handling costs of the cartridges, and other materials being

sent to the two locations and/or the audit laboratory for this project; recording the

number of cartridges sent, the manufacturer’s cartridge lot number being sent to

each location, and the shipment’s date.

7. The District is responsible for recordkeeping and shipping costs to return

exposed cartridges to the contractor.

8. If warranted, the contractor shall provide to the District specific instructions

detailing the specific procedures for handling the cartridges. If the contractor

prefers that the collected samples be returned to them using a specific kind of

container and/or cooling material, other than what the District proposes to use,

then the contractor must supply these materials to the District as part of the

contract. The containers/shipping materials must meet all Department of

Transportation and Federal Aviation Administration requirements for safe

handling and transport provided by shipping companies like UPS or FedEx. If

the contractor desires the District to use a particular written form for tracking the

exposed sample (i.e., a chain of custody (COC) form other than the form the

District provides), the contractor will supply a sufficient quantity of these forms for

use by District staff.
