PSC M1MC — Operation of EPG Facilities - Geothermal

Overview

The Product Service Code (PSC) system is a government-wide procurement taxonomy used for reporting the goods and services acquired by federal agencies; PSCs appear in FPDS/SAM entries and are maintained through the PSC Manual on Acquisition.gov.¹

PSC M1MC — Operation of EPG Facilities - Geothermal — sits under category M1: Operation of Structures and Facilities and is the designated FPDS code for actions described as “Operation of EPG Facilities - Geothermal.” The PSC Manual provides the code label but does not define the specific activities encompassed by “EPG Facilities” or expand the label into an operational checklist; therefore the exact scope beyond the code title is not specified by official sources.¹

What this PSC covers

• Operation of geothermal EPG facilities — activities not specifically defined in the PSC Manual.¹
• On-site facility operations (general descriptor; specific tasks not specified by official sources).¹
• Plant-control and monitoring activities (label implies operations but manual gives no task-level definition).¹
• Routine operations related to energy production at geothermal sites (manual provides only the code label).¹
• Reporting and classification of procurement actions where the predominant service is geothermal facility operation (selection guidance in PSC Manual).¹

How this code is used in FPDS and reporting

The PSC is entered in FPDS data element 8A and should represent the predominant product or service purchased on the reported contract action; environmental attributes are recorded in data element 8L for cases where applicable. The PSC Manual instructs selection by predominance but does not provide a task-level definition for M1MC.¹

Frequently asked questions

• When is M1MC the appropriate PSC to report on a contract?
  Use M1MC when the predominant service purchased aligns with operation of geothermal EPG facilities as labeled in the PSC Manual; selection must follow FPDS data-element guidance to reflect the primary product or service on the action. The manual does not list task-level boundaries for this code.¹

• Does the PSC Manual define “EPG” or list specific operational activities under M1MC?
  The PSC Manual lists the M1MC code and its title but does not expand the abbreviation “EPG” or enumerate the specific operational activities covered by the code; therefore the precise scope is not specified by official sources.¹

• Are there NAICS codes formally mapped to M1MC in the PSC Manual?
  The PSC Manual landing and supporting files host alignment spreadsheets and mapping tools; the static PDF code list does not include a full NAICS-to-PSC crosswalk for every code, so consult the Acquisition.gov PSC Manual resources or FPDS exports for mappings.²

• How should environmental attributes for geothermal operations be recorded?
  Environmental attributes (energy-efficient, biobased, environmentally preferable, etc.) are reported in FPDS data element 8L while the PSC is recorded in data element 8A; agencies should follow the FPDS definitions and reporting guidance in the PSC Manual and FPDS help resources.³
