What the government is buying
The U.S. Army Corps of Engineers, Seattle District is soliciting for National Pollutant Discharge Elimination System (NPDES) Laboratory Services for the CJD project. The contract structure includes a base period plus four option years.
NPDES laboratory services typically involve water quality testing and analysis required under the Clean Water Act. Facilities that discharge pollutants into waters of the United States must obtain NPDES permits, which require regular monitoring and reporting of discharge quality. Laboratory work under this type of contract generally includes sampling, analysis of pollutants, and preparation of reports in formats compliant with Environmental Protection Agency and state regulatory requirements. The "CJD" designation likely refers to a specific Corps project or facility requiring these environmental compliance services.

Who can bid
This is a full and open competition with no set-aside program, meaning businesses of any size may compete. The NAICS code 541380 corresponds to Testing Laboratories, which applies to establishments primarily engaged in performing physical, chemical, and other analytical testing services. While this is unrestricted, small businesses certified under SBA size standards for NAICS 541380 should verify their eligibility; see the solicitation for any applicable size thresholds.
To bid, vendors must be registered in SAM.gov and have any required laboratory certifications for environmental testing. NPDES-related work typically demands laboratories accredited under EPA methods or state-equivalent programs, such as Washington State Department of Ecology certification. See the solicitation for specific certification requirements and any mandatory qualifications.
How to put together a competitive bid
Understand the scope depth: The base-plus-four-option-years structure means pricing must remain competitive over a potentially five-year period. Analyze whether your lab can maintain staffing, equipment, and certification continuity across all periods. See the solicitation for the base period duration and option exercise terms.
Verify analytical capabilities: Confirm your laboratory can perform the specific EPA methods required for NPDES compliance monitoring. Common analyses include biochemical oxygen demand (BOD), total suspended solids (TSS), metals, nutrients, and other parameters specified in individual permits. Request the solicitation's technical specifications to match your capabilities exactly.
Address quality systems: Corps contracts for laboratory services emphasize documented quality assurance/quality control (QA/QC) procedures, chain-of-custody protocols, data deliverable formats, and holding time compliance. Prepare to detail your lab's QA manual, proficiency testing records, and electronic data deliverable capabilities.
Price strategically: Labor-intensive environmental testing contracts often weigh technical approach heavily. However, ensure your pricing covers travel to sampling locations in the 9328 ZIP code area, sample preservation, rush analyses, and reporting. See the solicitation for the government's estimated quantity or annual value to calibrate your pricing.
Past performance: Gather relevant contract references for NPDES or other Clean Water Act laboratory services. Corps evaluators value demonstrated experience with federal environmental compliance programs.
