PSC Y1NC

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies products and services in procurement records. PSC codes support consistent FPDS/SAM reporting, spend analysis, and category management; the Product and Service Code Manual is the authoritative maintenance and policy reference for PSC use.¹

PSC Y1NC appears on the federal PSC master list as "CONSTRUCTION OF POLLUTION ABATEMENT AND CONTROL FACILITIES." The consolidated PSC list provides the short-form label but does not publish a detailed scope, itemized inclusions/exclusions, or a canonical NAICS crosswalk for this entry; contracting officers should consult the PSC Manual and the current PSC master list when assigning codes.²

Contracting considerations

• Use-case guidance — When assigning PSC Y1NC, treat the code as the short-form label for construction of pollution abatement/control facilities and apply the PSC Manual selection rules: choose the PSC that best describes the procurement’s primary purpose and document that determination in the contract file.¹

• Scope determination — If the procurement’s primary requirement is construction (site work, civil/structural installation, erection of systems whose main purpose is pollution abatement or control), consider a construction PSC consistent with the PSC Manual; coordinate with contracting specialists to document the primary purpose and scope. Not specified by official sources for exhaustive system-level inclusions/exclusions.¹

• NAICS crosswalk and solicitation drafting — The PSC master list does not publish a canonical NAICS crosswalk for Y1NC; identify the NAICS code(s) that best describe the construction or professional services being procured and justify the choice in the procurement record.²

• Contract types and clauses — Typical vehicles for construction of pollution-control facilities include firm-fixed-price, cost-reimbursement (where appropriate), and design-build arrangements when design and construction are procured together; apply applicable construction clauses, wage determinations, environmental permits, and bonding as required by statute and agency policy. The PSC master list does not specify contract-type guidance; follow agency acquisition regulations and the PSC Manual for assignment practices.¹

• Documentation and reporting — Record the selected PSC on FPDS and retain rationale (scope statement and primary purpose) in the contract file to support auditability and spend-analysis consistency; the PSC Manual and PSC master list are the governing references for PSC use.¹
