This is a Memorandum for the Record documenting a sole-source acquisition justification under the simplified acquisition threshold.

The acquisition involves a Chloropac Power Supply and Associated Fuses required for delivery by September 5, 2026. The intended use is to replace a C3 C24062 Chloropac controller with a new T-ALT 624. The required source or brand name is Evoqua, specifically the Evoqua W3T346111 model. The document confirms that the required product(s) are not designated as critical ship equipment per COMSCINST 4490.1(series) and SMS Procedure 10.6-002-ALL.

The contracting officer has determined that only one responsible source is available and has selected this justification under section 3.a. The primary basis for the sole-source determination is restrictive rights (section 1), whereby the replacement part identified on N7/PM6 approved T-ALT 624 is only available directly from Evoqua. Additional supporting factors include standardization requirements per COMSCINST 4790.3 to maintain fleet configuration baseline with the Evoqua W3T346111 make and model, and compatibility considerations as the product serves as a direct replacement part for existing equipment. The PID Number is N32205-26-SIMACQ-DSM-N7-0337, and the memorandum is dated April 15, 2026.
