About this file
This is a Questions and Answers document dated June 10, 2026, issued by Contract Officer Joseph Kirk for the MORU Replace Propane Tank Farm Components contract. The document addresses six technical clarifications regarding the scope and requirements for replacing propane tank farm infrastructure.
The responses confirm that the scope includes replacement of buried impressed current cathodic protection (ICCP) anodes and insulated wiring in addition to the inoperable rectifier, as these components have exceeded their service life per industry standards (NACE, API, NFPA). The existing vaporizer burner gas meter should continue to be used unless inspection reveals failure or damage. Dielectric unions must be installed at the two-vaporizer inlet liquid lines to isolate the vaporizer from the ICCP rectifier system and prevent corrosion. The vaporizer first-stage outlet regulator, approximately 30 years old, must be replaced as part of the vaporizer assembly replacement to ensure reliability and compliance with modern safety standards. A temporary propane vapor supply plan is required only if overnight temperatures are predicted to fall below 32 degrees Fahrenheit for more than five consecutive hours and remain below freezing for more than three hours during daylight hours; given the anticipated July/August work start, this requirement is likely not applicable. Finally, the incorrectly installed ¾-inch back-check valve in the liquid supply must be removed and replaced with a properly oriented three-way valve to comply with NFPA 58 requirements and improve safety and serviceability.

MORU Replace Propane Tank Farm Components
Questions and Answers
Date: Jun 10, 2026
# Question Response 1 Is replacing the existing buried impressed current anodes and insulated wiring part of the scope, or only the inoperable rectifier?
Based on widely accepted industry practice and engineering standards (NACE, API, NFPA-related design norms). the ICCP Anodes have exceeded their service life and replacement is required and within the scope.
2 Should the vaporizer burner gas meter continue to be used?
Yes, the existing burner gas meter should continue to be used unless inspection reveals mechanical failure, inaccurate readings, or damage. It remains appropriate for monitoring gas flow to the vaporizer burner.
3 Should missing isolation dielectric unions be installed between the underground liquid services and above-ground equipment to isolate the vaporizer from the rectifier system?
Yes. Installing dielectric unions at the two-vaporizer inlet liquid lines is recommended. This prevents unintended current paths from the ICCP system into above-ground equipment, reduces corrosion risk, and aligns with standard practice for isolating mixed above-ground/buried systems.
4 The vaporizer first-stage outlet regulator is ~30 years old. Should it be replaced as part of the vaporizer replacement?
Yes. Given its age and the fact that the vaporizer assembly is being replaced, replacing the first-stage outlet regulator at the same time is recommended to ensure reliability, pressure control accuracy, and compliance with modern safety standards.
5 Should we plan to supply propane vapor to the facility during vaporizer replacement using temporary service or hoses?
At the time of replacement, If overnight temperatures are below freezing 32 degrees Fahrenheit for more than consecutive 5 hours and are predicted to last more than 3 hours during daylight hours, then yes A temporary vapor supply plan will be required. This ensures continuity of operations and allows the vaporizer replacement to proceed without service interruption. (The anticipated work is to start in July/August).
6 There appears to be an incorrectly installed ¾-inch back-check in the liquid supply. Should it be removed and replaced with a three-way valve to comply with NFPA 58?
Yes. Removing the incorrectly installed back-check valve and replacing it with a properly oriented three-way valve would bring the installation into alignment with NFPA 58 requirements and improve both safety and serviceability.
